P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 1‐7 the Salinas Treatment Plant No.1 (TP‐1), which is now a transfer station1 and approximately 7.7 miles of gravity and force main industrial sewer pipelines.

Flows to the IWCCS are collected and conveyed via gravity main and the Airport Lift Station and force main, which comprise the collection portion of the system upstream of the TP‐1 site. From the TP‐1 site, industrial wastewater flo ws by gravity via a 42‐inch diameter pipeline to the IWTF’s influent pump station to be processed at the IWTF.

The IWCCS accepts flow from 23 different facilities, which are primarily used for agricultural processing, such as fresh produce washing and packaging operations. The wastewater is conveyed to the IW TF site for disposal or recycling. Proposed improvements at the IWTF site and Airport LS site would provide operational and efficiency improvements as well as capacity reliability and redundancy enhancements for the industrial users. The City is evaluating different funding methods for these improvements, including State Revolving Fund (SRF) loans, recycle d water grants, and other State and federal funding options.

Project Background. The IWTF site was a private facility built in 1943 to serve as a vegetable wastewater treatment processing facility that processed agricultural wastewater for civilian and armed forces during World War II. Initially, the “facility” consisted of a series of percolation ponds spanni
ng approximately 20 acres with a 0.75‐million‐gallon per day (mgd) capacity. After the war, ownership was transferred to the City of Salinas. In 1966, the facility was expanded to increase wastewater treatment capacity to 1.5 mgd and included a series of anaerobic settling ponds. The ae ration lagoon was added in 1973, to enhance wastewater treatment and address odor control concerns. The IWTF now consists of 110 acres of percolation ponds and has an average monthly treatment capacity of 4 mgd.

In 1984, the Central Coast Regional Water Quality Control Board (RWQCB) prohibited discharge of IWTF effluent to the Salinas River. Therefore, a pu mp station was added to discharge water from the existing percolation ponds into drying beds rather than discharging to the Salinas River.

In 1987, the RWQCB modified the permit to allow discharge into the Salinas River during wet weather events, provided there is a 10 0 ‐to‐1 river‐to‐wastewater dilution. Since 2002, the City has been prohibited from discharging wastewater into the Salinas River because of historically low flow conditions in the Salinas River. In addition, the discharge of untreated wastewater to the percolation ponds or drying beds is prohibited. Because of recent im provements, the system now can transfer treated effluent for reuse and recycling to the Monterey One Water (M1W) Regional Treatment Plant (RTP).

Currently, the IWCCS accepts wastewater flow from 23 different industrial facilities in the southern area of the City. These industries are primarily performing food processing, which includes vegetable packaging, ice ma nufacturing, produce refrigeration, and manufacturing corrugated boxes. The industrial wastewater flows vary seasonally. Peak flow within the system

1 TP‐1 is the previous site of the City's municipal sewage treatment plant, which has been replaced with the Salinas Area Pump Station that conveys all City municipal wastewater to the Monterey One Water Regional Treatment Plant. TP‐1 also houses the Stormwater Pump Station and diversion structures for both stormwater and wastew ater.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 1‐8 occurs during the summer months, which coincides with the peak harvesting season. Flows are lower in the winter, which coincides with decreased harvesting. Each user operates under an individual industrial waste discharge permit that establishes limitations on wastewater flow and characteristics so that the overall IWTF can meet its permit for the General Wa ste Discharge Requirement (WDR) for Discharges of Fruit and Vegetable Processing Waste and Categorical Waiver of Report of Waste Discharge and Waste Discharge Requirements for Certain Small Discharge of Fruit and Vegetable Processing Waste (Order No. R3‐2004‐0066).

The City has been approached by a private deve lopment entity, which has requested additional flow allocations to serve near‐term development at the existing Merrill Street Campus along with anticipated additional flows from existing dischargers. This area is within the existing planned service area for the IWTF and is included in the City of Salinas General Plan.

Project Pur pose. The IWCCS and IWTF facilities, are approximately 80 years old and in need of improvements. The objectives of the project are listed below:

1. Provide reliability and redundancy to treat planned industrial wastewater and convey to end uses, including:
 Provide redundant equipment and backup power supplies.  Add reliability to transfer water to the IWT F site and to discharge the treated wastewater for reuse.
 Increase permitted average monthly IWTF treatment capacity from 4 million gallons per day (mgd) to 5.5 mgd to better serve existing and future planned customers.  Add reliability associated with transfers of treated wastewater to M1W RTP for reuse.

2. Improve au
tomation and control of the facilities, including more robust monitoring of the aerators, and improve the ability and flexibility to transfer and monitor flow of wastewater between ponds and to adjust treatment as needed.

3. Add energy and operational efficiency features to the IWTF.

The proposed project wo
uld not expand the capacity of the current systems to accommodate or promote population growth or development within the service area. Rather, the proposed project would address existing operational, treatment efficiency and disposal capacity issues to provide sufficient treatment and disposal capacity to accommodate existing and planned agricultural i
ndustrial activities within the City.

Proposed Project. The Industrial Wastewater Treatment Facility Improvements Project (proposed project) is comprised of the following four Capital Improvement Plan (CIP) projects identified in the Capacity and Financial Analysis Report2: (1) the Aeration Lagoon Improvements

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 1‐9 Project; (2) the Pond Automation/Distribution and Pond 3 Pump Station Project; (3) the Variable Frequency Drives (VFDs) and Backup Power Project; and (4) the Airport Lift Station Project. The intent is to package the IWTF improvements under a single contract but would likely deliver the Airport LS project separately. The major elements of each project componen t are described below and shown in Figure 3.

Aeration Lagoon Improvements. The existing Aeration Lagoon has twelve 50‐horsepower (hp) surface aerators installed. The Aeration Lagoon Improvements Project involves replacing three of these aerators with new units of the same capacity as the existing aerators, as the ex
isting units have exceeded their useful design life. An additional four 50‐hp aerators would be installed in the existing lagoon to provide additional treatment capacity. Proposed improvements would also include upgrades to existing electrical and communications systems – including running new electrical wiring, new motor control cent
ers, new electrical building(s), and new transformers. An area of the lagoon berm would be widened to accommodate a new electrical building and equipment. The new Electrical/Control Building is expected to have a footprint of 12 feet by 18 feet by 10 feet in height.

Pond Automation/Distribution and Pond 3 Pump Stat ion. Proposed improvements would include upgrades to provide additional control and automation to enhance flow monitoring and operation, including new concrete structures, piping/valves, water level controls, slide gates, and electrical and instrumentation upgrades. New piping would be provided between ponds and would be buried in the existing berms. The new flow control structures will allo w for portable pumping units to facilitate transfer of water between and around ponds allowing draining and maintenance of each pond. A new berm or sheet pile is being constructed in Pond 3 around the inlet to the Pond 3 Pump Station to facilitate operation and maintenance.

The Pond 3 Pu
mp Station upgrades would include the addition of a new second pump with the same capacity as the existing pump to enhance pumping reliability.

Variable Frequency Drives (VFD) and Backup Power. This project improvement would add new VFDs on the existing and proposed aerators to provide better control and o perational cost savings by reducing energy usage at appropriate times of day or seasons. VFDs would be installed in new electrical control located on the berm between the Aeration Basin and Percolation Pond 1.

The Backup Power project element would include the addition of three fixed standby emergency generators ca pable of generating up to a total of 1.5 megawatts (MW) to increase facility reliability/resiliency and to ensure uninterrupted wastewater conveyance and treatment in the event of power outages. Emergency generators would be installed adjacent to the IWTF influent pump station and an Aeration Lagoon substation with other electrical equipment.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 1‐19 Airport Lift Station (LS). The Airport LS project would increase the reliable capacity of the pump station from 4 mgd to 6 mgd monthly average flow to adequately serve the existing industrial uses that discharge to this pump station. Proposed improvements would include either replacing the existing pumps, expanding the lif t station to incorporate new pumps to provide the increased capacity, or replacing with a new lift station.

Project Construction. For the projects located at the IWTF site, construction would occur on City‐owned land within the boundaries of the IWTF. For the Airport LS project, construction would occur within existing roadway right‐of‐way or within land on which the Ci ty maintains an access easement.

The majority of the proposed improvements would include structural, mechanical, and electrical modifications within existing facilities. Construction of these items would require demolition/removal of some existing structures and equipment and installation of new structural, mechanical, and ele ctrical equipment. Site trenching for new underground piping and utility connections would also be required, not to exceed 12 feet deep. New facilities or structures would be located either in the same location as other structures planned for demolition/removal or in currently undeveloped areas within the boundaries of the IWT F. The maximum depth of excavation required for these facilities would be approximately 15 feet.

Existing structures, mechanical piping, and electrical equipment not incorporated with proposed improvements would be demolished and removed from the site.

The types of equipment that would be used for construction of proposed improvements would include but wou ld not be limited to the following:
 Backhoe
 Crane
 Boom truck
 Bulldozer
 Compactor
 Grader
 Drill rigs
 Haul trucks
The IWTF would continuously operate throughout the entire duration of construction. The IWTF would continue receiving, treating, and disposing industrial wastewater from its service area without inter
ruption for the entire duration of the project.

Construction of proposed improvements is anticipated to begin in July of 2023 and be completed by March 2026. Construction activities would generally be limited to the hours between 7:00 a.m. and 6:00 p.m. on weekdays and between 8:00 a.m. and 6:00 p.m . on Saturdays. No construction activities would be permitted on Sundays or holidays during any construction phases, except for emergencies and for critical work with prior notice to and approval by the City. Construction personnel may arrive on site and depart approximately one hour prior to or after regular constru ction times.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 1‐20 Project construction would require approximately 18,000 cubic yards of cut and 35,000 cubic yards of fill, resulting in approximately 17,000 cubic yards of soil and materials that would need to be imported to the project site.

Prior to construction, temporary contractor staging areas would be identified within the IWTF site and adjacent to the exi
sting Airport LS. Primary access for material hauling for the IWTF would occur along Davis Road.

The on‐site construction workforce would consist of laborers, craftsmen, supervisory personnel, support personnel, and construction management personnel. It is conservatively assumed that a maximum of 20 workers would be on‐site du ring construction activities.

Project Operation. The proposed project addresses operational, treatment efficiency and disposal capacity issues. At completion of the project, the IWTF will seek a permitted capacity increase for the WDR from a monthly average flow of 4 mgd to 5.5 mgd. Upon completion of construction activities, operation of the proposed projec t may require one additional employee, which would generate minimal additional vehicle trips to/from the project sites. Although implementation of the proposed project would improve operational efficiency, new facilities would be installed that would require additional electrical power for IWTF operation.

Alternatives Considered. For the purposes of the potential SRF a pplication, the City is obligated to look at other alternatives that could be implemented in lieu of the proposed project.

Alternatives considered and either dismissed or that merit further study are as follows:
 New Aeration Lagoon in Pond 1. This alternative would provide additional treatment capacity by building up a berm for a ne w aeration lagoon in Pond 1. This alternative would require construction of a new surrounding berm at an elevation above the flood plain due to Federal Emergency Management Agency (FEMA) requirements. It would also necessitate a permit from the Division of Safety of Dams.
 New Aeration La
goon on Agricultural Land adjacent to the IWTF. This alternative would provide additional treatment capacity by building a new aeration lagoon on adjacent property. This alternative would require acquisition of land from private property owners.  New percolation ponds in Agricultural Land adjacent to the IWTF. This alternative would provide addi
tional disposal capacity by creating new percolation ponds in lieu of transferring treated water to M1W RTP for reuse. This alternative would also require acquisition of land from private property owners.

Each of the above project alternatives results in varying temporary and permanent environmental impacts than the propo sed project, and which are compared in the Environmental Alternatives Analysis provided in Appendix A.

9. Surrounding Land Uses and Setting:

Existing conditions on and in the vicinity of the project sites are discussed below.

Existing IWTF. The majority of proposed improvements would be located at the existing IWTF located west of Davis Road, north of the Salinas River. The IWTF consists of an influent pu mp station, an aeration lagoon, percolation ponds, and drying beds. The IWTF design and permitted capacity is a 4.0 mgd monthly average dry weather flow and a 6.8 mgd peak flow.

Industrial wastewater enters the facility by gravity flow, first passing through a 3‐inch bar screen at the Influent Pump Statio n (IPS) to remove large debris. The IPS consists of three vertical, mixed‐flow type pumps. Influent is normally pumped from the IPS to the Aeration Lagoon and then flows by gravity to Percolation Pond 1, then Percolation Pond 2, and then to Percolation Pond 3. Discharge piping is also configur ed to allow for wastewater to be pumped to the Percolation Ponds directly from the IPS, if needed. In the event of pump failure or power outage, a bypass pipe diverts flow from the IPS to an emergency storage basin. Flow is reintroduced to the IPS from the emergency storage basin via a sluice gate loca ted in the IPS.

Pumps and discharge piping allow flows to be pumped from Percolation Pond 3 to the existing drying beds.

The Aeration Lagoon is a 13‐acre, 38 million‐gallon pond that provides biochemical oxygen demand (BOD)3 reduction to meet discharge requirements. Oxygen and mixing are provided through mechanical surface aerators and mixers to aid in treatment. The aerators float on top of the lagoon and provide mixing and oxygen transfer to the wastewater. The level of mixing attained by the aerators is insufficient to maintain solids suspension. As a result, th e solids either settle to the bottom of the lagoon or are carried over to the downstream percolation ponds or drying beds. Wastewater flows by gravity out of the discharge weirs to the percolation ponds or drying beds.

The three Percolation Ponds have a total capacity of 110 acres. W astewater flows by gravity from the Aeration Lagoon into Percolation Pond 1. From Percolation Pond 1, wastewater flows via gravity into Percolation Ponds 2 and 3. Piping from the Aeration Lagoon enables water to travel directly to Percolation Ponds 2 or 3, if needed, via the diversion structure. Water de pths in the ponds range from 8 to 10 feet, exclusive of freeboard depth.4 During normal operation, water flows via gravity through Percolations Ponds 1 and 2 into Pond 3 for treatment and infiltration. Excess water that cannot be treated within the percolation ponds is pumped into the drying beds through the Lift Station at Percolation Pond 3 to a series of 54 shallow ponds that provide addi tional percolation and evaporation capacity for the IWTF. In the

3 BOD represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic (oxygen is present) conditions at a specified temperature. The BOD is an important parameter for assessing water quality because sewage with high BOD can cause a decrease in oxygen of receiving waters, whi ch can affect the health of aquatic organisms. 4 Ponds are required to maintain a 2-foot freeboard or depth from the berm top to the water surface to prevent spills.

Once treated, the industrial wastewater either evaporates, percolates into the groundwater, or is pumped to the M1WRTP where the wastewater is further treated and reused for either agricultural irrigation or as source water for the Pure Water Monterey potable re use facilities.

Airport LS. The City operates one lift station that services industrial users. The Airport Lift Station contains three pumps (25 hp each) and conveys flow via the downstream gravity system to the IWTF.

10. Other Public Agencies Whose Approval is R equired (e.g., permits, financial approval, or participation agreements):
 Central Coast RWQCB
 Monterey Bay Air Resources District

11. Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resource Code section 21080.3.1? If so, is there a plan for consultation th at includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? In September 2022, the City provided formal notification to those California Native American tribes that are traditionally and culturally affiliated with the geographic area within which the proposed project is located pursuant to the consul tation requirements of Assembly Bill (AB) 52.

Letters were sent to all tribal representatives identified by the Native American Heritage Commission. A copy of the AB 52 letter is provided in Appendix B. To date, one tribal contact responded to confirm receipt of the notification; however, no requests for cons ultation have been received.

Except as provided in Public Resources Code Section 21099, would the project:
a. Have a substantial adverse effect on a scenic vista? b. Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?

c. In non‐urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from a publicly accessible vantage point.) If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations gov erning scenic quality?

d. Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?

3.1.1 Discussion
a. Would the project have a substantial effect on a scenic vista? (Less‐Than‐Significant Impact) A scenic vista is defined as a viewpoint that provides expansive views of a highly valued landscape for the benefit of the public. Aesthetic components of a scenic vista generally include: (1) scenic quality, (2) se nsitivity level, and (3) view access. The proposed project is located in an area that is primarily characterized by farmlands and the Salinas River. Development in the project vicinity includes local roads, industrial sites (agricultural warehouses and shipping and receiving buildings) at the Airport Lift Station, and infrastructure associated with the IWT F (e.g., influent pump station, solar panels, fencing) at the IWTF site. The Airport Lift Station site is at the terminus of Airport Boulevard and therefore is not visible from any highly traveled public roads. The IWTF site is only visible from Davis Road and not from surrounding public viewpoints, such as St ate Route (SR‐68).

Furthermore, there are no designated scenic vistas in the vicinity of the proposed project per the Monterey County General Plan (2010).

Project construction activities would include subsurface disturbance and excavation; vehicle and truck trips; use of heavy equipment (e.g., loaders, excavators, backhoes); and building new facilities.

Construction activities at the IW
TF site could be visible to motorists on Davis Road. However, these activities would only be visible temporarily during the construction period.

Implementation of the proposed project would result in the upgrade/replacement of existing facilities and the construction of new facilities. The majority of these faciliti es would be located either within or adjacent to existing facilities (e.g., berms, ponds) or underground (e.g., piping) and

New buildings and pump stations would be consistent with the existing facilities on site (e.g., equal to or shorter than existing structures). Therefore, the proposed project would not have a substantial adverse effect on a scenic vista. b. Would the project substantially damage scenic reso urces, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? (No Impact) SR‐68 is the closest designated State Scenic Highway to the proposed project; it is approximately 2 miles east of the IWTF site. Because of this distance, viewers on SR‐68 do not have views of the proposed project. No historic buildings or rock outcr
oppings are located on or near the vicinity of
the project area. Furthermore, implementation of the proposed project would not result in the removal of or damage to scenic resources. Therefore, no impacts to scenic resources within a State scenic hig
hway would occur.
c. In non‐urbanized areas, would the project substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from a publicly accessible vantage point.) If the project is in an urbanized area, would the pr
oject conflict with applicable zoning and other regulations governing scenic quality? (Less‐Than‐Significant Impact)
The regional landscape establishes the general visual environment of the project area. The character of the landscape in the vicinity of the IWTF site is rural. The land use is agriculture, and large cultivated fields flank both sides of the st
retch of Davis Road near the IWTF site. Overhead utility lines supported by wood poles line the west side of Davis Road. Existing facilities associated with the IWTF, including the influent pump station, dirt access road, solar array and security fencing are visible from Davis Road. Uniq ue or outstanding landscape elements are generally absent, except for the Salinas River Corridor. The Salinas River runs just south of the IWTF site. The river itself is mostly not visible to the public; however, it flows within a channel that contains numerous trees and shrubs. The vegetation in the Salinas Riv er Channel creates a unique visual feature in a primarily agricultural landscape.

Project construction activities for the IWTF improvements include subsurface disturbance and excavation; vehicle and truck trips; use of heavy equipment (e.g., loaders, excavators, backhoes); and building new facilities. Construction activities associated with the IWTF improvements could be visible to motorists on Davis Road. Howe
ver, these activities would only be visible temporarily during the construction period.

Implementation of the IWTF improvements would result in the replacement of existing facilities on site and construction of new facilities, including new aerators within the existing Aeration Lagoon, new electrical wiring, new motor contro l centers, a new electrical building(s), new transformers, a new concrete structure for flow and level monitoring equipment, and new pump stations within each percolation pond. These facilities would be constructed within the IWTF site and all above‐ ground facilities would be consistent in mass and size with the ex isting facilities on site.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐3 The Airport LS site is entirely paved and surrounded by industrial uses. After the completion of construction, proposed improvements at the Airport LS site would be located underground and out of view.

Therefore, the proposed project would not degrade the existing visual character or quality of the project sites and its surroundin gs, and this impact would be less than significant. d. Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? (Less‐Than‐Significant Impact) Streetlights, vehicle headlights and taillights, and lighting associated with the existing IWTF and Airport LS sites are th
e existing sources of light and glare in the project area. Daytime sources of glare include reflections off light‐colored surfaces and windows.

The proposed project would provide operational and efficiency improvements as well as capacity reliability and redundancy enhancements, including installation and replacement of aerators, installation of new pipi
ng and pump stations, and upgrades to existing electrical and communications systems. These improvements would not include a lighting component; therefore, these features would not create substantial light that would adversely affect nighttime views.

The proposed project would not create a substantial new source of daytime glare. Glare is a phenom
enon that exists when there is a very high degree of contrast between bright and dark areas in a field of view that makes it difficult for the human eye to adjust to differences in brightness.

Proposed improvements would be not be visible because they would be un derground, within percolation ponds, and/or enclosed in new concrete buildings, or consist of dull metal with low glare potential; therefore, these features would not create substantial glare that would adversely affect day or nighttime views.

Therefore, the project would not create a new source of substantial light or glare which would adversely affect day or nigh
ttime views in the area. This impact would be less than significant.

3.2 AGRICULTURE AND FORESTRY RESOURCES
In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, i ncluding timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment Project; and the forest carbon measurement methodology provided in Forest P rotocols adopted by the California Air Resources Board.

Common examples include residential, industrial, commercial, institutional facilities, cemeteries, airports, golf courses, sanitary landfills, sewage treatment and water control structures. A small portion of the IWTF site is classified as agricultural by the FMMP. However, thi
s agriculturally designated land is currently part of the IWTF operations, and implementation of the proposed project would not change the use of the agriculturally designated land. Therefore, the proposed project would not convert Prime Far mland, Unique Farmland, or Farmland of Statewide Importance to a non‐agricultural use, and no impact would occur.
b. Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract? (No Impact)
Zoning. Portions of the IWTF site are zoned F/40 (Farmlands), including areas along the Salinas River, as well as the existi
ng Aeration Lagoon. These areas are already developed as part of the existing IWTF; therefore, implementation of the proposed project would not result in any impacts to farmlands zoned F/40. Monterey County Zoning Ordinance Title 21 allows for “public and quasi‐ public uses” as an Allowable Use, subj ect to a Use Permit within areas that are zoned F/40 (Section

21.30.050B). The proposed project would implement improvements within the existing IWTF, which is considered to be an allowable use within the existing land use zoning designation. The proposed project would not conflict with existing zoning for agricultural use, and no impacts would occur.

Williams
on Act Lands. The California Land Conservation Act of 1965 (the Williamson Act) is a voluntary program that incentivizes the preservation of farmland. Monterey County has approximately 735,000 acres of land designated as Williamson Act Preserves, including 32,000 acres of land under the Farmland Se curity Zone (Monterey County General Plan 2010). Neither the IWTF site nor the Airport LS site are under Williamson Act contract. Therefore, implementation of the project would not conflict with existing zoning for agricultural use, or a Williamson Act contract, and no impacts would occur.
c. Would the project conflict with exi sting zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? (No Impact)
The proposed project is not located on forest land or tim berland, and would not conflict with existing zoning for, or cause rezoning of, forest land, timberland, or timberland zoned Timberland Production. Therefore, implementation of the proposed project would not result in impacts to forestland.
d. Would the project result in the loss of forest land or conversion of forestland to non‐forest use? (No Impact)

d. Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?

3.3.1 Discussion
The proposed project is located in unincorporated Monterey County and the City of Salinas, within the jurisdiction of the Monterey Bay Air Resources District (MBARD), which regulates air quality in the North Central Coast Air Basin (NCCAB). Air quality in the planning area is not only affected by various emission sources ( mobile, industry, etc.), but also by atmospheric conditions such as wind speed, wind direction, temperature, and rainfall.

Within the MBARD, ambient air quality standards for ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter (particulate matter less than 10 microns in size [PM10] and particulate matter less than 2.5 microns in size [PM2.5]), and lead have been set by both the State of California and the federal government. The State has also set standards for sulfate and visibility. The MBARD is currently designated as non‐attainment for State O3 and PM10 standards. a. Would the project conflict with or obstruct implementation of the applicable air quality plan? (Less‐Than‐Significant Impact)
An air quality plan describes air pollution control strategies to be taken by counties or regions classified as non‐attainment areas. The main purpose of an air quality plan is to bring a non‐ attainme
nt area into compliance with the requirements of federal and State air quality standards.

The air quality plan uses the assumptions and projections provided by local planning agencies to determine control strategies for achieving regional air quality compliance.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐8 The applicable air quality plans are the 2012–2015 Air Quality Management Plan (AQMP),6 which was adopted on March 15, 2017, and the 2005 Report on Attainment of the California Particulate Matter Standards in the Monterey Bay Region, which was adopted on December 1, 20057. The 2012–2015 AQMP is the most recent MBARD plan for attaining California Ambient Air Quality Standards and addresses attainment of the State O3 standard. The 2012–2015 AQMP also serves as an assessment and update to the 2012 Triennial Plan, which documents the MBARD’s progress towards attaining the State O3 standard. The 2005 Report on Attainment of the California Particulate Matter Standards in the Monterey Bay Region describes State particulate matter requirements and analyzes emission reductions to achieve the State PM10 standard. For a project in the NCCAB to be consistent with these air quality plans, the pollutants emitted from the project must not exceed the MBARD significance thresholds or cause a significant impact to air quality. As discussed below, construction and operation of the proposed project would not result in the gen eration of criteria air pollutants that would exceed the MBARD thresholds of significance. Therefore, the proposed project would not conflict with or obstruct implementation of the MBARD air quality plan. Therefore, the project would not conflict with or obstruct implementation of the applicable air quality plan, and this impact would be less than signifi cant.
b. Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non‐attainment under an applicable federal or state ambient air quality standard? (Less‐Than‐Significant Impact)
The MBARD area is in non‐attainment for State O3 and PM10 standards. Past, present, and future development projects contribute to the region’s adverse air quality impacts on a cumulative basis.

By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in non‐attainment of ambient air quality standards. Instead, it is a project’s individual emissions combi
ned with the emissions of other local and regional projects that together cause cumulatively significant adverse air quality impacts. If a project’s contribution to the cumulative impact is considerable, then the project’s impact on air quality would be considered significant.

In developing thresholds of significance for air polluta nts, MBARD considered the emission levels for which an individual project’s emissions would be cumulatively considerable. If a project exceeds the identified significance thresholds, its emissions would be cumulatively considerable, resulting in significant adverse air quality impacts to the region’s existing air quality conditions. The following analysis assesses whether the proposed project would result in a cumulative ly considerable increase of criteria pollutants during construction and operation of the proposed project.

Construction Emissions. During construction, short‐term degradation of air quality may occur due to the release of particulate matter emissions (i.e., fugitive dust) generated by grading, hauling, and other activities. Emissions from constru ction equipment are also anticipated and would include CO,

Project construction would involve grading, site preparation, paving, and other activities. The disturbance of soils and associated fugitive dust would temporarily generate particulate emissions, and if not properly controlled, would have the greatest construction‐related effects on air quality.

Unless prop erly controlled, vehicles leaving the site would deposit dirt and mud on local streets, which could be an additional source of airborne dust after it dries. PM10 emissions would vary from day to day, depending on the nature and magnitude of construction activity, local weather conditions, soil moisture, silt content of soil, and wind speed. Larger dust particles would settle near the source, while fine particles would be dispersed over greater distances from the construction site. Water or other soil stabilizers can be use d to control dust, resulting in emission reductions of 50 percent or more.

In addition to dust‐related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, O3, NO2, SO2, and some soot particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area, CO and other emissions from traffic would increase slightly while those vehicles idle in traffic. These emissions would be temporary in nature and limited to the immediate area surrounding the construction site.

Construction emissions were estimated for the project using the Ca lifornia Emissions Estimator Model (CalEEMod) version 2020.4.0, consistent with MBARD recommendations. The proposed project is estimated to involve approximately 2 acres of ground disturbance, which was included in CalEEMod. Construction of the proposed project is anticipated to occur Monday through Saturday, beginning in July 2023 and endin g in March 2026, which was also included in CalEEMod. In addition, the CalEEMod analysis conservatively assumed that construction of the proposed project would have a maximum of 20 workers on site during construction activities. Project construction would require approximately 18,000 cubic yards of cut and 35,000 cubic yards of fill, r esulting in approximately 17,000 cubic yards of soil and materials that would need to be imported to the project site, which were also included in CalEEMod. Construction‐related emissions are presented in Table 3.A. CalEEMod output sheets are included in Appendix C.

As shown in Table 3.A, emissions associated with construction of the project would be well below MBARD’s significance thresholds for daily for ROG, NOx, CO, PM2.5, and PM10 emissions. Therefore, construction of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non‐attainment under an applicable federal or State ambient air quality standards, and impacts would be less than significant.

Operational Emissions. Long‐term air pollutant emis sion impacts are typically associated with mobile sources (e.g., vehicle trips), energy sources (e.g., electricity and natural gas), and area sources (e.g., architectural coatings and the use of landscape maintenance equipment) related to a project.

As discussed above, the proposed project would implement improvements to IWTF and the Airport LS, which wo uld include structural, mechanical, and electrical modifications within the existing facilities. Upon completion of construction activities, operation of the proposed project may require one additional employee. In addition, although implementation of the proposed project would improve operational efficiency, new facilities would be installed that would require additional electrical power for IWTF and Airport LS operation.

Emission esti
mates for operation of the project were calculated using CalEEMod. Based on Section

3.17, Transportation, no vehicle trips are anticipated with implementation of the proposed project, which was included in CalEEMod. In addition, the proposed project is expected to consume an additional approximately 3,066,454 kilowatt‐hours (kWh) per yea r, which was included in CalEEMod.

The proposed project would also include the addition of three fixed standby emergency generators capable of generating a total of 1.5 megawatts (MW), which was also included in CalEEMod. Model results are shown in Table 3.B. CalEEMod output sheets are included in Ap pendix C.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐11 The results shown in Table 3.B indicate the project would not exceed MBARD’s significance criteria for daily ROG, NOx, CO, PM10 or PM2.5 emissions. Therefore, operation of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non‐attainment under an applicable federal or State ambient air quality standard.

Impacts would be less than significant.
c. Would the project expose sensitive receptors to sub stantial pollutant concentrations? (Less‐ Than‐Significant Impact)
Sensitive receptors are defined as people that have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds, day‐care centers, nursing homes, hospitals, and residential dwelling units. The closest sensitive receptors to the project sites incl ude residential areas located approximately 2,500 feet north of the project site.

Construction activities can expose sensitive receptors to airborne particulates and fugitive dust as well as a small quantity of construction equipment pollutants (i.e., diesel‐fueled vehicles and equipment). However, as shown in Table 3.A above, project construction pollu tant emissions would be well below the MBARD significance thresholds and once the project is constructed, the project would not be a source of substantial emissions. Therefore, sensitive receptors would not be exposed to substantial pollutant concentrations during project construction and operation, and impacts would be considered less than significant.
d. Would th e project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? (Less‐Than‐Significant Impact) During project construction, some odors may be present due to diesel exhaust. However, these odors would be temporary and limited to the construction period. Once operational, the proposed project would include new percolation ponds at th
e IWTF site; however, the ponds would be
treating wastewater from local agriculture‐based industries not sewage. As such, the proposed project is not expected to generate odors. In addition, the distance to the nearest sensitive receptors from the IWTF site is approximately 2,500 feet, therefor e, any odors generated by the facilities would readily dissipate. Work at the Airport LS involves increasing the capacity of the existing pumps. Pumps do not cause odors. Therefore, the proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substa ntial number of people, any impact would be less than significant.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐13 a. Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special‐status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? (Less th an Significant with Mitigation Incorporated) At the time of the field survey, the IWTF BSA contained wastewater treatment ponds and associated infrastructure (mapped as developed areas), an irrigation canal, cultivated and tilled agricultural fields, a detention basin, disturbed/barren areas, and ruderal (e.g., disturbed, weedy) patches of mostly nonnative/invasive herbaceous plan t species. Riparian woodland associated with the Salinas River is present in the southern portions of the IWTF BSA.

The Airport Lift Station BSA is primarily developed and contains several small patches of ruderal and ornamental vegetation. A total of 38 wildlife species were observed on or near the BSAs during the August 2022 survey. F
requently observed species included barn swallow (Hirundo rustica), mallard (Anas platyrhynchos), and great blue heron (Ardea herodias). Each of the 38 species observed commonly occur in and around the Salinas River watershed.

The literature review identified 47 special‐status plant species that are known to occur wi thin a nine‐quadrangle radius of the proposed project BSAs. The majority of the rare plant species that were identified in the databases have specialized habitat requirements (i.e., wetland habitats, dunes, vernal pools, etc.) that do not occur within the project sites or BSAs. Based on review of th e literature and site observations coupled with the habitat suitability analysis, no special‐status plant species are expected to occur within the project sites or to be adversely affected by the proposed project. Therefore, the proposed project would have no impact on special‐status plants.

The literature review identified 49 specia l ‐status animal species that are known to occur within a nine‐quadrangle radius of the BSAs. Of those 49, 22 special‐status animal species have documented California Natural Diversity Database records within a 5‐mile radius of the BSAs. One special‐status animal species, Monterey hitch (Lavinia exilicauda harengus), has been docu mented in the Salinas River in areas adjacent to the IWTF within the IWTF BSA. No special‐status animal species have been documented within the Airport Lift Station BSA. No special‐status animal species or signs of such species were observed within the Airport LS or the IWTF proje ct sites during the field survey.

While special‐status bird and bat species have potential to forage in the vicinity of the IWTF site, these highly mobile species would be expected to avoid the site during construction activities. As such, construction activities within the IWTF site are not anticipated to result in dire ct impacts to any special‐status animal species. However, construction activities at the IWTF could involve temporary increases in noise, dust, and vibration, which could indirectly impact common and special‐status bird species that have potential to nest within the riparian habitat along the Salinas River adjacent to the IWT F site. Cliff swallows are also known to nest on the pump station within the IWTF, and the IWTF site contains suitable nesting habitat for a variety of ground‐nesting birds and birds that could nest in the ruderal vegetation on the margins of the site or within the irrigation canal. Nesting birds are pr otected under the California Fish and Game Code and federal Migratory Bird Treaty Act. Construction activities that occur during the nesting bird season (typically January 1 through August 31) have potential to result in the direct or indirect take of nesting birds, which

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐14 would be considered a significant impact. With implementation of Mitigation Measure BIO‐1, which recommends avoiding ground‐disturbing activities during the bird nesting season if possible or avoidance measures if ground‐disturbing activities take place during the nesting season, impacts to nesting birds (including special‐status bird species) would be reduc ed to a less‐than‐significant level.

The Airport Lift Station project site is completely developed and does not contain suitable habitat for any special‐status animal species.
b. Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or region al plans, policies, regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? (Less than Significant with Mitigation Incorporated)
One natural community under the jurisdiction of the California Department of Fish and Wildlife, riparian woodland, was mapped along the southwestern border of the IWTF BSA; however, this natural com
munity is outside of the limits of the IWTF site and, therefore would not be directly impacted by proposed project activities. The riparian woodland could be indirectly impacted during project activities, including from an increase or change in off‐site runoff, erosion, noise/vibration, and spread of invasive species. To avoid or minimi ze indirect impacts, Mitigation Measures BIO‐2 and BIO‐3 would be implemented to address proper erosion control and storage of construction equipment and the spread of invasive plant species. With implementation of Mitigation Measures BIO‐2 and BIO‐3, impacts to sensitive natural communities would be le ss than significant.

No sensitive natural communities are located within the Airport Lift Station BSA. The Airport Lift Station project would not directly impact any special‐status natural communities. c. Would the project have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, ver nal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? (Less than Significant with Mitigation Incorporated) The IWTF site contains an irrigation canal and the IWTF BSA includes a portion of the Salinas River.

Proposed improvements to the IWTF would be entirely outside of and some distance from an y aquatic resources associated with the Salinas River (including riparian habitat), and no new encroachment/fill is expected to occur in resources associated with the Salinas River.

Additionally, planned improvements such as the new pipelines between percolation ponds, which are part of the Pond Automation/Distribution would be placed along existing roads/berms and would avoid direct impacts to th
e irrigation canal. Construction of the proposed pipelines could result in indirect temporary impacts to the irrigation canal and Salinas River such as dust, potential fuel spills from construction equipment, construction‐related runoff, and erosion. Construction activities involving ground disturbance could also result in the intr oduction and/or proliferation of non‐native, invasive plant species, which could outcompete and/or displace native vegetation within the irrigation canal or adjacent riparian habitat areas. To avoid or minimize such indirect impacts, proper erosion control and storage of construction equipment would be required, as specified in Mitigation Measure BIO‐2. Furthermore, to avoid the spread of invasive plant species, Mitigation I NITIAL S TUDY /M ITIGATED N EGATIVE D ECLARATION N OVEMBER 2022

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐15 Measure BIO‐3 is recommended. With implementation of Mitigation Measures BIO‐2 and BIO‐3, potential indirect impacts to aquatic resources would be less than significant.

As previously discussed, the wastewater treatment ponds do not meet the definition of a jurisdictional water of the United States or water of the St ate. Therefore, no mitigation is required for any improvements to the wastewater treatment ponds. d. Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? (L ess ‐Than‐Significant Impact) The wildlife species that occur in the project vicinity are adapted to the urban‐wildland interface and ongoing IWTF operations, and the project would not introduce new effects to the areas. The noise, vibration, light, dust, or human disturbance within construction areas would only temporarily deter wildlife from using areas in the immedia
te vicinity of construction activities. These indirect effects could temporarily alter migration behaviors, territories, or foraging habitats in select areas.

However, because wildlife species are already conditioned to the activities associated with the proposed project, they would most likely re‐establish their use of the sites once all tem porary construction effects have been removed. The proposed project would not place any permanent barriers within any known wildlife movement corridors or interfere with habitat connectivity. The impact would be considered less than significant, and no mitigation is required. e. Would the project conflict with any local polici es or ordinances protecting biological resources, such as a tree preservation policy or ordinance? (No Impact) Protected trees within Monterey County are regulated by the County of Monterey Zoning Ordinance, Title 21, Chapter 21.64.260 – Preservation of Oak and Other Protected Trees (tree ordinance). Construction of the proposed project would occur enti rely within existing City facilities and would not require the removal of any trees, including any trees protected by local policies or ordinances. Therefore, the proposed project would not conflict with any local policies or ordinances protecting biological resources. No mitigation is required. f. Would the project conflict with the prov isions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? (No Impact)
The proposed project does not fall in an area with an adopted Habitat Conservation Plan, Natural Communities Conservation Plan, or other approved local, regional, or State habitat conservation plan, and th
erefore would not present a conflict with any such plan. No mitigation is required.

If nesting birds are discovered during preconstruction surveys, the biologist shall identify and delineate an appropriate buffer (depending on the circumstances and specific bird species) where no clearing, grading, or construction activities with potential to have direct or indirect impacts on the nesting birds are allowed to take place unti l after the birds have fledged from the nest, or the qualified biologist has determined that the nest is no longer active.

If a nesting bird survey is required, written results of the survey by the biologist shall be submitted to the City of Salinas (City) prior to the start of g round‐ disturbing activities.

BIO‐2 Erosion Control and Best Management Practices (BMPs). Prior to the start of construction, the Project Contractor shall clearly delineate all construction areas and equipment staging areas. The designated areas shall be located in such a manner as to prevent any loose soil or spill runoff fr om entering the irrigation canal, the Salinas River, or adjacent riparian vegetation communities. All equipment maintenance, staging, and dispensing of fuel, oil, or any other such activities used by the Project Contractor shall occur in these designated staging areas.

Prior to the start of construction, ad equate erosion and sedimentation barriers (e.g., silt fencing) shall be installed around the perimeters of work areas by the Project Contractor and remain in place during project construction to prevent any sediment or debris from entering the adjacent irrigation canal or Salinas River. For work areas adjacent to the Salinas Riv er or irrigation canal, barriers shall consist of a minimum 3‐foot‐tall silt fencing buried to a depth of approximately 3–6 inches below the soil surface (or as otherwise specified in a project‐specific erosion control or spill prevention plan). These barriers shall be inspected by the Project Contractor on a regular basis, and maintai

BIO‐3 Invasive Species Control. Any non‐native plants removed during the course of construction shall be contained and properly disposed of off site. All mulch, to psoil, seed mixes, or other plantings used for erosion‐control shall be free of invasive plant species seeds or propagules. No plant species listed on the California Invasive Plant Council (Cal‐IPC) inventory shall be installed in the project sites, and all plant palettes proposed to be installed on the project sites shall be re viewed and approved by a qualified biologist.

3.5.1 Discussion
The analysis provided in this section is based on background research, a field survey, and additional fieldwork as discussed below.

3.5.1.1 Historical Resources
CEQA defines a “historical resource” as a resource that meets one or more of the following criteria:
 Listed in, or eligible for listing in, the California Register of Historical Resources (California Register);
 Listed in a local register of historical resources;
 Identified as significant in a historical resource survey meeting the requirements of Section 5024.1(g) of the Public Resources Code; or
 Determined to be a historical resource by a project's lead agency.

A historical resource consists of “Any object, building, structure, site, area, place, record, or manu‐ script which a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California . . . Ge
nerally, a resource shall be considered by the lead agency to be ‘historically significant’ if the resource meets the criteria for listing on the California Register of Historical Resources” (California Code of Regulations Title 14(3) § 15064.5(a)(3)). Archaeological resources may also be considered historical resources.

LSA con
ducted background research and a field survey for cultural resources for the project. At LSA’s request, staff of the Northwest Information Center (NWIC) conducted a records search of the project site and a 0.25‐mile radius (NWIC File No. 22‐0231) on August 15, 2022. The NWIC, an affiliate of the California Hi storical Resources Information System, is the official State repository of cultural resource records and reports for Monterey County. As part of the background research, LSA also reviewed local and State inventories for cultural resources, contacted the Native American Heritage Commission (NAHC) in Sacramento, and consulted results of previous archival resear ch

Industrial Wastewater Treatment Facility. The records search did not identify any previously recorded historic period‐built environment resources within the IWTF. The records search identified one previously recorded historic period‐built environment resource within a 0.25‐mile radi us of the IWTF (Bridge No. 44C‐0068), the Davis Road Bridge over the Salinas River. This structure was evaluated by LSA in 2014 as part of the Davis Road Bridge Replacement and Road Widening Project9 and was determined to not be eligible for the National Register.

Background research, previous evaluations by LSA cultural resource staff for an adjacent project, and a field survey indicated that IWTF site is the location of a former Salinas Municipal Dump, a sewage farm, and a site to process wastewater from i ndustrial food canning and related agricultural operations. A description of this historical land use pattern is below.

Disposal of sewage upon open land began in England in the 1850s and was the chief method of sewage disposal until the 1870s. In the United States, sewage farming was a popular method on New Englan
d farms to grow crops; the first municipal sewage farm was operated in Pullman, Illinois, in 1881. Sewage farming was more widespread in the arid western states as a productive use of scarce water, especially in California for growing crops in areas with little rain. In 1898, Maggie McBride gran ted land in the project site (Assessor’s Parcel No 207‐041‐028) to the City of Salinas for use as a sewage farm, beginning the association of the project site with waste management that continues to this day.

The movement for a regional water quality and sewage treatment plant came at a ti me when Salinas Sewage Treatment Plant No. 1, an activated sludge plant built in 1929 on Hitchcock Road

After being processed in the plant, the dried solid waste was transported to the Davis Road facility, spread over the sewage farm parcel near Davis Road, and disced into the soil.

After World War II, rapid population growth required a change in the scope of sewage treatment in the Salinas area and Monterey County. Officials in M
onterey, Pacific Grove, and the Seaside County
Sanitation District sought a regional approach to address the booming population, which required professionally designed treatment facilities with higher capacities. Sewage farming had largely been curtaile
d by the time the Monterey Peninsula Water Pollution Control Agency formed in 1971. After 1971, the cities of Seaside, Del Rey Oaks, Sand City, and Salinas; sanitation districts in Castroville, Moss Landing, and Boronda; the military installation at Fort Ord; and Monterey County joined together to form a regional sewage and wastewater treatment pl ant. In 1977, the newly formed Monterey Regional Water Pollution Control Agency began to purchase existing treatment plants and outfalls of its member entities, including Salinas’s sewage treatment facilities.

Initially designed to process 1.5 million gallons of sewage daily, the demand on Sewage Treatment Plant No. 1 had grown to over five milli on gallons by 1970, the majority of which came from industrial agricultural plants such as canneries. A proposed expansion of treatment capacity system‐ wide called for enlarging the existing ponds and installing aerators to meet the increased demand and prevent raw sewage and industrial agricultural effluent from polluting the Salinas River. By 1977, the over‐capaci
ty situation was so dire that noxious smells were being emitted, forcing the City of Salinas to excavate the dried sewage ponds at Sewage Plant No. 1, transport the soils to the Davis Road site, and dispose of the material through the spread‐an d‐discing method.

According to a review of plans, a field survey, archival research, and other information provided by the City, the existing IWTF has undergone numerous modifications, equipment upgrades, and expansions in response to steady population growth and to comply with current wastewater treatment technology, regulatory wastewater treatment, and odor manage ment standards.

Field survey results indicated the IWTF has the built environment characteristics of a general industrial/utilitarian aesthetic found throughout the Salinas Valley and California with subsequent alterations to several of the core buildings to accommodate increased processing loads, wastewater treatment and odor regulations, and facility personnel levels. Al though the core of this cluster of built environment features meets the general age requirement of 50 years for consideration as historic properties under Section 106 of the National Historic Preservation Act of 1966 (as amended) and as a historical resource under CEQA, and is significant in the context of Salinas’ munici pal development in the mid‐to‐late 20th century, the IWTF does not appear eligible for listing in the California Register due to a lack of historical integrity, nor does it otherwise constitute a historical resource for the purposes of CEQA.

Airport Lift Station. The Airport LS site is at the south end of Airpo rt Boulevard near Hansen Street in Salinas. The records search did not identify any previously recorded historic period‐built environment resources within the Airport LS site. A field survey by LSA cultural resource staff indicates the buildings on the property appear recently built or renovated within the last 15 years.

3.5.1.2 Archaeological Resources
The records search identified one prehistoric archaeological cultural resource within the IWTF project site (P‐27‐000580), and two historic‐period archaeological resources within a 0.25‐mile radius of th e IWTF project site (P‐27‐003057 and P‐27‐003058). No archaeological resources have been identified within or within 0.25‐mile of the Airport LS site. The prehistoric resource that was previously recorded within the IWTF project site was first identified during construction of a portion of the IWTF in 1972 bu t was not formally recorded until 1973.

A pedestrian field survey was conducted on August 22, 2022, to check for surficial archaeological materials within the project site (both IWTF and Airport LS project sites). The field survey was negative for archaeological resources. Subsurface testing (shovel test pits and hand‐auger holes) was condu
cted throughout the IWTF project site in areas of proposed project‐related ground disturbance on September 26, 27, and 28, 2022, to ascertain the presence or absence of subsurface archaeological remnants of the previously recorded prehistoric resource or any previously unrecorded resources. The subsurface archaeological testing, which was cond ucted in P‐27‐000580 and in other areas of proposed ground disturbance associated with the project, was negative for the presence of prehistoric and historic‐period archaeological resources within the IWTF project site.

Four criteria are used for determining whether an archaeological resource is eligible for listing in the California Re
gister. To be eligible for listing, the resource must meet at least one of the four criteria below.
 Associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States (Criterion 1).  Associated with the lives of persons important to local, California or national history (Criterion 2).
 Embodies the distinctive characteristics of a type, period, region or method of construction or represents the work of a master or possesses high artistic values (Criterion 3).  Has yielded, or has the potential to yield, information important to the prehistory or history of the local area, California or the nation (Criterion 4).

As documented in its original site record, P‐27‐000580 is not associated with any specific events, nor is it associated with the lives of specific individuals im portant to local, California, or national history.

Additionally, as the resource is not a built environment in nature, it does not embody the distinctive characteristics of any type, period, region, or method of construction and it does not represent the work of a master. Additionally, the lack of subsurface archaeological remnants (inclu ding a lack of prehistoric midden deposits) associated with the recorded location of P‐27‐000580 suggests that the resource does not have potential to yield information important to the prehistory of the local area, California, or the nation. As such, prehistoric archaeological resource P‐27‐000580 (the only I NITIAL S TUDY /M ITIGATED N EGATIVE D ECLARATION N OVEMBER 2022

Would the project cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? (No Impact)
As describe
d above, the cluster of built environmental features at the IWTF does not appear eligible for listing in the California Register due to a lack of historical significance, nor does it otherwise constitute a “historical resource” for the purposes of CEQA. Additionally, prehistoric archaeological resource P‐27‐000580 (recorded wi thin the IWTF project site) does not appear eligible for listing in the California Register because it does not meet any of the four criteria for listing, nor does it otherwise constitute a “historical resource” for the purposes of CEQA. As such, the proposed project would not cause an advers e change in the significance of a historical built environment or archaeological resource.
b. Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? (Less Than Significant with Mitigation Incorporated) As discussed above, subsurface archaeological testing was negative for the presence of pre historic and historic‐period archaeological resources within the IWTF project site. However, archaeological subsurface testing units were consistently terminated at 150 centimeters (5 feet) or shallower due to lack of artifacts or midden deposits and/or impassable rocks in the units, and project‐related excavation could reach between 12 and 15 feet belo w existing surface for pipeline installation. As such, the absence of archaeological resources in the subsurface testing units is not necessarily indicative of the absence of archaeological resources in deeper sediments of the project site.

As described above, the IWTF site has been previously disturbed as a result of the various ph ases of construction (e.g., 1958 through 1969 and in 1972) and prehistoric archaeological resource P‐27‐ 000580 (recorded within the IWTF project site) does not appear eligible for listing in the California Register because it does not meet any of the four criteria for listing, nor does it otherwise constitu te a “historical resource” for the purposes of CEQA. Nevertheless, the recordation of P‐27‐000580 within the IWTF project site (as well as the recordation of historic‐period archaeological resources P‐ 27‐003057 and P‐27‐003058 within 0.25‐mile of the IWTF project site) suggests that additional, previously unidentifi ed subsurface archaeological cultural resources could be identified during project‐related ground disturbing activities. The Airport LS site contains subsurface geological sediments that partially date to a time period that includes human occupation of the region, but no previously recorded archaeological resources are within the Airport LS site or a 0.25‐mile r adius of the Airport LS site.

To avoid or minimize impacts to previously unidentified archaeological resources that may be determined significant per CEQA, archaeological monitoring of all ground‐disturbing project activities associated with the IWTF project site would be required, as specified in Mitigation Measure CUL‐1. In addition, in the event that cul tural materials are encountered during grading/construction at either the IWTF site or the Airport LS site, all work shall cease until the find has been evaluated and mitigation measures put in place for the disposition and protection of any

With implementation of Mitigation Measure CUL‐1, potential impacts to significant archaeological resources would be less than significant. c. Would the project disturb any humans remains, including those interred outside of formal cemeteries? (Less Than Significant Impact)
As discussed above, subsurface archaeo logical testing was negative for the presence of prehistoric and historic‐period archaeological resources within the IWTF project site, including human remains.

If human remains are encountered at any time during project implementation, State Health and Safety Code Section 7050.5 and State CEQA Guidelines Section 15064.5(e)(1) state that no further disturbance sh all take place in the area of the find until the County Coroner has made a determination of origin and disposition of the human bone pursuant to Public Resources Code (PRC) Section 5097.98. The County Coroner must be notified of the find immediately and shall make a determination within two working days of being notif ied. If the remains are determined to be Native American, the County Coroner shall notify the NAHC by phone within 24 hours, and the NAHC shall then immediately determine and notify a Most Likely Descendant (MLD). With the permission of the landowner or his/her authorized representative, the MLD may ins pect the site of the discovery. The MLD shall complete the inspection and make recommendations or preferences for treatment of the remains within 48 hours of being granted access to the site. The MLD’s recommendations may include scientific removal and nondestructive analysis of human remains and items associated with Native Am
erican burials, preservation of Native American human remains and associated items in place, relinquishment of Native American human remains and associated items to the descendants for treatment, or any other culturally appropriate treatment.

Compliance with Section 7050.5 of the California Health and Safety Code and PRC Section 5097.98 regarding th e treatment of human remains would ensure that potential impacts to human remains would be less than significant.

3.5.2 Mitigation
CUL‐1 Archaeological Monitoring and Treatment of Unanticipated Discoveries. An archaeologist (either an archaeologist who meets the Secretary of the Interior’s Professional Qualifications Standards for Archeology or an archaeologist supervised by such an archaeologist) shall monitor all ground‐disturbing activities associated with project implementation at the Industrial Wastewater Treatment Facility (IWTF) site. In the event that archaeological resources are identified du
ring project activities at either the IWTF site or Airport Lift Station site, work shall be halted immediately within 50 feet of the find until a qualified professional archaeologist can assess the nature and significance of the find and determine if any additional study or trea

The archaeologist shall then develop proper mitigation measures required for the discovery per California Code of Regulations [CCR], Title 14, Chapter 3, Section 15064.5(f)). Additional studies could include, but would not be limited to, collection and documentation of artifacts, documentation of the cul tural resources on State of California Department of Parks and Recreation Series 523 forms, or subsurface testing.

3.6.1 Discussion
a. Would the project result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources during project construction or operation? (Less Than Significant Impact)
The following section describes the proposed project’s construction and operation related to energy consumption.

Construction‐Period Energy Use. The proposed project would r equire demolition, grading, site preparation, building, paving, and architectural coating activities during construction. Construction of the proposed project would require energy for the manufacture and transportation of construction materials, preparation of the site for grading activities, and construction of the proposed park improvements. Petroleum fuels (e.g., diesel and gasoline) would be the pri mary sources of energy for these activities. Construction contracts would be required to comply with applicable California Air Resources Board (CARB) regulations restricting the idling of heavy‐duty diesel vehicles and fuel efficiency. Compliance with State regulations would reduce the inefficient, wasteful, or unnecessary consumption of energy. In addition, con struction activities are not anticipated to result in an inefficient use of energy as gasoline and diesel fuel would be supplied by construction contractors who would conserve the use of their supplies to minimize their costs on the project. Energy usage on the project sites during construction would be temporary in nat ure and would be relatively small in comparison to the State’s available energy sources. Therefore, construction energy impacts would be less than significant.

Operational Energy Use. Operational energy use is typically associated with natural gas use, electricity consumption, and fuel used for vehicle trips associated with the project. The proposed project would not requir
e natural gas; therefore, operational energy use associated with the proposed project would be related to electricity consumption and fuel used for vehicle trips.

As discussed above, the proposed project would implement improvements to the IWTF and Airport LS, which would include structural, mechanical, and electrical modifications within th e existing facilities. Upon completion of construction activities, operation of the proposed project may require one additional employee. Based on Section 3.17, Transportation, no additional trips are anticipated I NITIAL S TUDY /M ITIGATED N EGATIVE D ECLARATION N OVEMBER 2022

In addition, although implementation of the proposed project would improve operational efficiency, new facilities would be installed that would require additional electrical power for IWTF and Airport LS operation. The proposed project is ex
pected to consume an additional approximately 3,066,454 kWh per year. Although operation of the proposed project would result in an increase in the consumption of electricity, the purpose of the proposed project is to implement improvements, that use energy more efficiently to accomplish project operations. The refore, although the proposed project would require additional electrical power, the proposed project would improve its collection, treatment, and disposal activities by improving operational and energy efficiencies and therefore, would not result in the wasteful, inefficient, or unnecessary consumption of energy resources. Impacts would be less than s ignificant.
b. Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? (Less Than Significant Impact)
In 2002, the Legislature passed Senate Bill (SB) 1389, which required the California Energy Commission (CEC) to develop an integrated energy plan every two years for electricity, natural gas, and transport
ation fuels, for the California Energy Policy Report. The most recently adopted CEC energy report is the 2022 Integrated Energy Policy Report Update.10 The 2022 Integrated Energy Policy Report Update provides the results of the CEC’s assessments of a variety of energy issues facing California. Many of these issues will require action if the State is to meet its climate, energy, air quality, and other environmental goals while maintaining energy reliability and controlling costs.

The 2022 Integrated En
ergy Policy Report covers a broad range of topics, including implementation of the Clean Energy and Pollution Reduction Act (SB 350), integrated resource planning, distributed energy resources, transportation electrification, solutions to increase resiliency in the electricity sector, energy efficiency barriers faced by disadvantaged communities, energy demand response, transmission and lands
cape‐scale planning, the California Energy Demand Preliminary Forecast, the preliminary transportation energy demand forecast, renewable gas (in response to SB 1383), updates on California electricity reliability, natural gas outlook, and climate adaptation and resiliency.

As indicated above, energy usage during construction would be relatively small in comparison to the State’s available en
ergy sources, and energy impacts would be negligible at the regional level. Once operational, although the proposed project would require additional electrical power, the proposed project would improve operational efficiency and would not result in the wasteful, inefficient, or unnecessary consumption of energy resources. Because the project would im prove energy efficiency and would not result in an impact on regional energy supplies, the proposed project would not

The project sites are not located within a designated Earthquake Fault Zone.11 Therefore, the proposed project would not expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving the rupture of a known earthquake fault.
ii. Strong seismic ground shaking? (Less Than Significant with Mitigation Incorporated) The project sites are located in a seismically active region subject to strong seismic grou nd shaking.

Ground shaking is a general term referring to all aspects of motion of the earth’s surface resulting from an earthquake, and is normally the major cause of damage in seismic events. The extent of ground‐shaking is controlled by the magnitude and intensity of the earth quake, distance from the epicenter, and local geologic conditions. The magnitude of a seismic event is a measure of the energy released by an earthquake; it is assessed by seismographs that measure the amplitude of seismic waves. The intensity of an earthquake is a subjective measure of the perceptible eff ects of a seismic event at a given point. The Modified Mercalli Intensity scale is the most commonly used scale to measure the subjective effects of earthquake intensity. It uses values ranging from I to XII.12 The closest fault to the project sites is the San Andreas Fault, located approximately 17 miles to the northeast of the project sites. Other active faults that could potentially affect the project area include the Palo Colorado‐San Gregorio Fault Zone and the Monterey Fault Zone, which lie to the west and nor thwest, respectively.13
No habitable structures would be constructed as part of the project. Although seismic ground shaking may occur in the project area, proposed improvements would be designed and constructed consistent with the most current version of the California Building Code (CBC), which includes specifications and design criteria to minimize damage from anticipated grou nd shaking. It is acknowledged that seismic hazards cannot be completely eliminated, even with site‐specific geotechnical investigation/design and advanced building practices. However, the seismic design standards of the CBC have been developed to mitigate seismic hazards and to prevent catastrophic building failure in the most severe earthquakes currently anticipated. Complia nce with the CBC, and other regulatory provisions, as required in Mitigation Measures GEO‐1 and GEO‐2, would reduce potential impacts associated with ground shaking to a less‐than‐significant level. Therefore, the project would result in a less‐than‐significant impact related to increasing the exposure of people or structures to ground shaking compared to existi
ng conditions.
iii. Seismic‐related ground failure, including liquefaction? (Less Than Significant with Mitigation Incorporated)
Liquefaction is the transformation of saturated, loose, fine‐grained sediment to a fluid‐like state because of earthquake shaking or other rapid loading. Soils most susceptible to liquefaction are

The California Geological Survey (CGS) has mapped Seismic Hazard Zones that delineate areas susceptible to liquefaction and/or landslides that require proposed new develop ments in these areas to conduct additional investigation to determine the extent and magnitude of potential ground failure. According to mapping by CGS,14 both the IWTF and Airport Lift Station sites are located in an area that has not been evaluated for liquefaction or landslides. According to the Preliminary Geotechnical Memorandum prepared for the adjacent Davis Road Bridge Replacement and Road Widening Project,15 soil liquefaction potential is relatively high for the loose sands located within the Salinas River Channel, just south of the IWTF project site. Mapping available from the Monterey County Geologic Hazards Map16 indicates that the IWTF and Airport Lift Station project sites are located in an area of low and high liquefaction susceptibility.

As specified in Mitigation Measure GEO‐1, prior to finalizing the design of project improvements, a qualified geotechnical engineer shall conduct a detailed geotechnical investigation to confirm subsurface site conditions. The site‐specific fin dings and recommendations of the geotechnical investigation shall be incorporated into the final design of the project improvements and submitted to the City for review and approval prior to the start of project construction. With implementation of Mitigation Measures GEO‐1 and GEO‐2, the impact of seismic‐re lated ground failure, including liquefaction, associated with construction and operation of the proposed project, would be less than significant.
iv. Landslides? (No Impact)
Seismically induced landslides and other slope failures are common occurrences during or soon after earthquakes in areas with significant ground slopes. Both of the project sites are relatively flat. No substantial nat
ural slopes exist at either project site. According to Geographic Information Systems (GIS) data available from the County, there is low susceptibility for landslides throughout the project area.17 The potential for seismically induced landslides to occur at the project sites would be the same as in the existing condition. There is no potential for the proposed project to expose people or structures to impacts related to landslides.
b. Would the project result in substantial soil erosion or the loss of to psoil? (Less Than Significant Impact)
The potential for soil erosion exists during the period of earthwork activities and between the time when earthwork is completed and new vegetation is established or hardscape is installed. Initial

Additionally, during a storm event, soil erosion could occur at an accelerated rate. The increased erosion potential could result in short‐term water quality impacts as identified in Section 3.10, Hydrology and Water Qual ity. Under the Construction General Permit, a Stormwater Pollution and Prevention Plan (SWPPP) must be prepared prior to any ground‐disturbing activities. The SWPPP would provide the details of the erosion control measures to be applied on the project sites during the construction period, including best management practices (BMPs) for erosion contr
ol that are recognized by the Regional Water Quality Control Board (RWQCB). In addition, the proposed project would be required to comply with the City of Salinas Standards to Control Excavations, Cuts, Fills, Clearing, Grading, Erosion and Sediments, as specified in Chapter 29, Stormwater Management and Discharge Control of the City of Sali nas Municipal Code. A grading permit will also be required, subject to review and approval by the City Engineer to ensure that impacts to topography and soil are reduced to a level of insignificance. Compliance with State and local regulations regarding stormwater during construction, including preparation and implementation of a SWPP P would ensure that the proposed project would result in less‐than‐ significant impacts related to erosion during construction.

Implementation of the proposed project would result in a nominal increase in impervious surface area, which would not substantially increase volume of runoff during a storm that would increase the potential for soil erosion on site. The
refore, implementation of the project would result in a less‐ than‐significant impact related to soil erosion and the loss of topsoil. c. Would the project be located on a geologic unit or soil that is unstable, or that would become unstable as a result of th e project, and potentially result in on‐ or off‐site landslide, lateral spreading, subsidence, liquefaction or collapse? (Less Than Significant Impact) As indicated in Section 3.7.a.iv above, the project sites are relatively flat and, according to the Monterey County Geologic Hazards Map, are not located in an area identified as susceptible to landslides. Th
ere is no potential for seismically induced landslides to occur on the project sites. No mitigation is required.

Liquefaction‐induced lateral spreading is defined as finite, lateral displacement of gently sloping or flat‐laying ground as a result of pore‐pressure buildup or liquefaction in a shallow underlying deposit toward a free face such as an excavation, chan
nel, or open body of water. Lateral spreading is
generally caused by liquefaction of soils with gentle slopes. Although there is a potential for liquefaction at both the IWTF and Airport Lift Station sites, the topography is flat and therefore, there is low potential for la
teral spreading. Furthermore, proposed improvements would be designed and constructed in accordance with standard engineering practices and the CBC, which includes specifications for site preparation. Therefore, potential impacts associated with liquefaction‐induced lateral spreading would be less than significant.

Collapsible soils are defined as any unsaturated soil that goes thro ugh a radical rearrangement of particles and greatly decrease in volume upon wetting, additional loading, or both. Soils subject to collapse do not occur at the project sites. Furthermore, according to the United States Geological I NITIAL S TUDY /M ITIGATED N EGATIVE D ECLARATION N OVEMBER 2022

Therefore, the proposed project would not be located on a geologic unit or soils that would become unstable, or expose people or structures to landslide, lateral spreading, subsidence, liquefaction, or collapse. Impacts would be less than significant. No mitigation is r equired. d. Would the project be located on expansive soil, as defined in Table 18‐1‐B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? (Less Than Significant with Mitigation Incorporated)
Expansion and contraction of volume can occur when expansive soils undergo alternating cycl es of wetting (swelling) and drying (shrinking). During these cycles, the volume of the soil changes markedly. Expansive soils are common throughout California and can cause damage to foundations and slabs unless properly treated during construction. According to the Natural Resources Conservation Service Web Soil Survey,19 the IWTF site contains three soil types: Mf (Metz fine sandy loam), MnA (Mocho silt loam, 0 to 2 percent slopes), and SbA (Salinas clay loam 0 to 2 percent slopes). 20 These soils are primarily silts and loams and are not considered expansive. The Airport LS site is entirely paved but underlain by the following soil type: AeC (Antioch very fine sandy loam, 2 to 9 percent slopes)21, which is not considered an expansive soil.22 The proposed project would be designed and constructed using standard construction methods and in compliance with the CBC, as required per Mitigation Measures GEO‐1 and GEO‐2. Adherence to the CBC requirements would ensure that geotechnical design of the proposed project would reduce potential impacts related to expansive soils. Therefore, expansive soils would not pose a risk to life or property, and this impact would be le
ss than significant with mitigation incorporated.
e. Would the project have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of waste water? (No Impact)
Septi
c tanks and alternative wastewater disposal systems would not be installed at either of the project sites. Therefore, implementation of the proposed project would not result in impacts to soils associated with the use of such wastewater treatment systems. No impact would occur.

The IWTF project site is located primarily on Holocene sediment from the Salinas River, which includes geologic units such as surficial sediments (Qg and Qa) from the Holocene age. Holocene surficial sedi
ment (Qg) consists of stream channel gravel and sand. Holocene surficial sediment (Qa) consists of alluvial gravel, sand, and silt/clay of valley areas and floodplains. Holocene‐age deposits are too recent for paleontological resources to be encountered. Any plant or animal remains that may be present would not have had s ufficient time to fossilize and would also be contemporaneous with modern species; therefore, they are not considered scientifically significant. In addition, the majority of the construction activities associated with implementation of the proposed project would involve minor ground disturbance that would not extend to a depth where fossils occur.

Therefore, the proposed projec t would not directly or indirectly destroy a unique paleontological resource or unique geologic feature. This impact would be less than significant.

Would the project:

3.8.1 Discussion
Greenhouse gases (GHGs) are present in the atmosphere naturally, are released by natural sources, or are formed from secondary reactions taking place in the atmosphere. The gases that are widely seen as the principal contributors to human‐induced global climate change are:
 Carbon dioxide (CO2);
 Methane (CH4);
 Nitrous oxide (N2O);
 Hydrofluorocarbons (HFCs);
 Perfluorocarbons (PFCs);
 Sulfur hexafluoride (SF6); and
 Nitrogen trifluoride (NF3).

Over the last 200 years, humans have caused substantial quantities of GHGs to be released into the atmosphere. These extra emissions are increasing GHG concentrations in the atmosphere and enhancing the natural greenhouse effect, believed to be causing global warming. While manmade GHGs include naturally‐occurring GHGs such as CO2, methane, and N2O, some gases, like HFCs, PFCs, SF6, and NF3 are completely new to the atmosphere.

Certain gases, such as water vapor, are short‐lived in the atmosphere. Others remain in the atmos‐ phere for significant periods of time, contributing to climate change in the long term. Water vapor is excluded from the list of GHGs above because it is short‐lived in the at mosphere and its atmospheric concentrations are largely determined by natural processes, such as oceanic evaporation.

These gases vary considerably in terms of global warming potential (GWP), a concept developed to compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP is based on sev
eral factors, including the relative effectiveness of a gas to absorb infrared radiation and length of time that the gas remains in the atmosphere (“atmospheric lifetime”). The GWP of each gas is measured relative to CO2, the most abundant GHG. The definition of GWP for a particular GHG is the ratio of heat trapped by one unit mass of the GHG to the ratio of heat trapped by one unit mass of CO2 over a specified time period. GHG emissions are typically measured in terms of pounds or tons of “CO2 equivalents” (CO2e).

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐34 For the purposes of this analysis, the stationary source threshold developed by the MBARD (10,000 metric tons [MT] of CO2e per year) is considered to determine the significance of GHG emissions. a. Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? (Less‐Than‐Significant Impact) The following section describes the proposed project’s construction and operational related GHG emissions and con tribution to global climate change. As discussed below, the proposed project would not generate substantial GHG emissions that would have a significant effect on the environment, and this impact would be less than significant.

Construction Emissions. Construction activities, such as demolition, site preparation, site grading, on‐site heavy‐duty construction vehicles, equip ment hauling materials to and from the site, and motor vehicles transporting the construction crew, would produce combustion emissions from various sources. During construction of the proposed project, GHGs would be emitted through the operation of construction equipment and from worker and builder supply vendor vehicles, each of which typically use fossil‐based fuels to operate. The combustion of fossil‐based fuels crea tes GHGs such as CO2, CH4, and N2O. Furthermore, CH4 is emitted during the fueling of heavy equipment.

Exhaust emissions from on‐site construction activities would vary daily as construction activity levels change.

Project construction emissions were analyzed using CalEEMod. Results of the analysis indicate that construction would result in approximately 835.7 MT of CO2e over the construction period. The MBARD does not provide guidance for analyzing GHG emissions during construction; therefore, this analysis amortizes the construction emissions over 30 years (the expected lifespan of the project) and adds the amortized construction emissions to the operational emissions. Based on the 30‐year lifespan of the proposed projec t, the proposed project would result in GHG emissions of approximately 27.9 MT CO2e per year.

Operational Emissions. Long‐term air emission impacts are typically associated with mobile, area, waste, and water sources and indirect emissions from sources associated with energy consumption.

Mobile‐source GHG emissions include project‐generated vehicle trips to and from a project. Area‐ source emissions are typically associated with activities such as landscaping and mainte nance on a project site. Energy source emissions are generated at off‐site utility providers as a result of increased electricity demand generated by a project. Waste source emissions generated by projects include energy generated by land filling and other methods of disposal related to transporting and managing pr
oject‐generated waste. In addition, water source emissions are typically generated by water supply and conveyance, water treatment, water distribution, and wastewater treatment.

As discussed above, the proposed project would implement improvements that would include structural, mechanical, and electrical modifications within the existing facilities. Upon completion of construction activities, operation of the proposed projec t may require one additional employee. In addition, although implementation of the proposed project would improve operational efficiency, new facilities would be installed that would require additional electrical power for IWTF and Airport LS operation.

3.17, Transportation, no vehicle trips are anticipated from implementation of the proposed project, which was included in CalEEMod. In addition, the proposed project is expected to consume an additional approximately 3,066,454 kWh per year, which was in cluded in CalEEMod. The proposed project would also include the addition of three fixed standby emergency generators capable of generating a total of 1.5 MW, which was included in CalEEMod. Model results are shown in Table 3.C. CalEEMod output sheets are included in Appendix C.

As shown in Table 3.C, the proposed project would generate approximately 354.1 MT of CO2e per year, which is well below the MBARD’s stationary source threshold of 10,000 MT of CO2e per year.

As such, the proposed project would not generate GHG emissions that would have a significant impact on the environment. This impact would be less than significant. b. Would the project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse g ases? (Less Than Significant Impact) The County of Monterey adopted the Municipal Action Plan in 2013 and expects to achieve the 2020 goals for emissions reductions. Currently, the County of Monterey is embarking on an effort to develop its Community Climate Action Plan and Adaptation Plan for 2030 to reduce GHG emissions in line with th
e targets set by the State of California. The City of Salinas is also developing its General Plan Update, Vision Salinas 2040, which would include Salinas’ first Environmental Justice Element and Climate Action Plan. In absence of any other local plans to reduce GHG emissions, the proposed project was evaluated against goals un
der AB 32, SB 32, and Executive Order S‐3‐05. As discussed in Section 3.8.a, the project’s short‐term construction and long‐term operational GHG emissions would be minimal and would not exceed the established threshold. In addition, the purpose of the

3.9.1 Discussion
a. Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? (Less Than Significant Impact) Hazardous materials are chemicals that could potentially cause harm during an accidental release and are defined as being toxic, corrosive, flammable, reactive, an irritant, or strong sensiti zer.

Hazardous substances include all chemicals regulated under the United States Department of Transportation23 “hazardous materials” regulations and the Environmental Protection Agency (EPA)24 “hazardous waste” regulations. Hazardous wastes require special handling and disposal because of their potential to damage public health and the environment.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐38 Exposure to hazardous materials during the construction of the project could result from the improper handling or use of hazardous substances or an inadvertent release resulting from an unforeseen event (e.g., fire, flood, or earthquake). The severity of any such exposure is dependent upon the type, amount, and characteristic of the ha zardous material involved; the timing, location, and nature of the event; and the sensitivity of the individual or environment affected.

Project construction would likely require the use of limited quantities of hazardous materials, such as fuels, oils, lubricants, and solvents. The small quantities of hazardous materials that would be transported, used, or disp
osed of would be well below reportable quantities. The improper use, storage handling, transport, or disposal of hazardous materials during construction could result in accidental release exposing construction workers, the public, and the environment, including soil and/or ground or surface water to adverse effects. Construction activities would be condu cted with standard construction practices and in accordance with all applicable California Division of Occupational Safety and Health and other safety regulations to minimize the risk to the public.

Compliance with federal, State, and local hazardous materials laws and regulations would minimize the risk to the public presented by these pote ntial hazards during construction of the project.

Transportation of any hazardous materials generated by excavation is regulated by the federal Department of Transportation and the California Department of Transportation (Caltrans). As such, transportation of hazardous materials off site must be handled by licensed hazardous waste haulers.

The IWTF currently treats i ndustrial wastewater discharges from the City of Salinas, using a biological treatment system including aeration, percolation ponds, and drying beds. Operation and maintenance of IWTF improvements would also involve the transport, use, storage, and disposal of small quantities of common water treatment chemicals (e.g., cleaners, fuels, lubricants, hydraulic fluids) consistent with existing operations. The IWT F discharges treated water back to the Salinas River groundwater sub‐basin under General WDR Order No. R3‐2004‐0066. The WDR requires groundwater monitoring for water quality parameters, including total dissolved solids, nitrate, pH, sodium, chloride, and sulfate. Sampling does not include organic or inorganic hazardous mate rials ‐ related contaminants, such as volatile organic compounds. The City demonstrates WDR compliance through a Monitoring and Reporting Program. Project improvements at the Airport LS include improving or replacing an existing pump. Operation and maintenance activities would be consistent with existing operations and would not involve a change in the existing use or transport of hazardous mat
erials.

Construction and operation of the proposed project would be required to comply with the Uniform Fire Code and local building codes for the storage of hazardous materials and construction of structures containing hazardous materials. Furthermore, construction and operation of the proposed project would comply with exi sting safety regulations and widely‐accepted industry standards, which would minimize potential hazards to the public and the environment from the use or transport of hazardous materials. Therefore, potential impacts associated with the transport, use, storage, handling, and disposal of hazardous materials during operation of the project would be less than significa
nt.

Would the project create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? (Less Than Significant Impact) Hazardous materials most likely to be used during construction include typical construction materials such as gasoline, diesel, motor oil, lubri cants, solvents, and adhesives. Such materials would be kept at construction staging areas, and would be secured when not in use. In the unlikely event of a spill, fuels would be controlled and disposed of in accordance with applicable regulations.

Drips and small spills would be the most likely potential hazardou s materials releases to occur; however, any release that occurs in close proximity to a stream or drainage channel could have a significant impact on the environment, if not properly controlled. The City would be required to prepare and implement a SWPPP for the proposed project in accordance with the St ate Water Resources Control Board (SWRCB) National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (NPDES General Construction Permit)(Order No. 2009‐0009‐DWQ, as amended by 2010‐0014‐DWG and 2012‐0006‐DWQ, NPDES No. CAS000002), which would reduce the pote ntial for hazardous materials releases to impact adjacent aquatic resources (i.e., the Salinas River and irrigation channel), and would reduce the potential for spills to impact sensitive habitat or human health, to a less‐than‐significant level. Therefore, construction of the proposed project would not create a significant hazard to the public or envir onment. This impact would be less than significant.

As described in Section 3.9.a above, operation of the proposed project would involve the use of hazardous materials, which is consistent with existing operations. Use of these materials would be conducted in compliance with federal, State, and local require ments. Therefore, no hazards or hazardous materials impacts related to long‐term operation of the project are anticipated. c. Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one‐quarter mile of an existing or proposed school? (No Impact)
The proposed project is not locate d within 0.25 mile of an existing or proposed school, and there are no schools within the project area. Therefore, implementation of the proposed project would not result in any impacts associated with emitting hazardous emissions or handling hazardous or acutely hazardous materials, substances, or waste within 0.25 mile of an ex isting or proposed school. No mitigation is required.
d. Would the project be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environme nt?

According to the SWRCB Geotracker website,25 several Cortese List sites or other hazardous material release sites are located within 2 miles of the IWTF site but are at such a distance or have a limited extent of contamination such that they do not impact the environmental condition of the IWTF project site.

Four hazardous materials sites are loca ted within 1,000 feet of the Airport LS site. All four of these leaking underground storage tank sites have been designated as “Completed—Case Closed.”26 No significant hazard to the public or environment would be associated with any of these listed sites, which are all closed. A closed site indicates that regulatory requirements for response actions, such as site assessment and remediation, have either been completed or were not necessary and therefore potential migration of residual conta minants in groundwater beneath the project sites (if any) would not likely pose a risk to human health and the environment.

Therefore, implementation of the proposed project would not create a significant hazard to the public or the environment as a result of being on a list of hazardous material sites compil ed pursuant to Government Code Section 65962.5. No mitigation is required. e. Would the project be located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project result in a safety ha zard or excessive noise for people residing or working in the project area? (No Impact) The proposed project involves improvements to an existing industrial wastewater facility and does not include a housing component. The IWTF project site is not located within an airport land use plan, or within 2 miles of a publ ic airport or public use airport. The closest airports to the IWTF site are the Salinas Municipal Airport, located approximately 7 miles to the northeast, and the Marina Municipal Airport, located approximately 3.6 miles to the west of the IWTF site. The Airport Lift Station site is just south of the Salinas M unicipal Airport; however, proposed improvements at the Airport Lift Station would include replacement or rehabilitation of an existing lift station, which is underground and would not create a safety hazard or result in excessive noise. Therefore, the proposed project would not result in a safety hazard or excessive noise for peo ple working at the project sites. No impact would occur.
f. Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? (Less Than Significant Impact) The Monterey County Multi‐Jurisdictional Hazard Mitigation Plan,27 which is currently being updated, is applicable at both the IWTF and Airport Lift Station sites.

Construction of the IWTF improvements would occur within the boundaries of the existing IWTF site. Construction of Airport Lift Station improvements would occur partially within public right‐of‐way, w hich may require portions of public rights‐of‐way to be closed during construction. However, emergency access would still be maintained. Because the proposed project would not alter or block adjacent roadways at either project site, implementation of the proposed project would not be expected to impair the function of nearby e
mergency evacuation routes. Therefore, the proposed project would have a less‐than‐ significant impact on implementation of an adopted emergency response plan or emergency evacuation plan.
g. Would the project expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires?

3.10.1 Discussion
a. Would the project violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality? (Less Than Significant Impact) The IWTF project site is located in the northern half of the Central Coast Region and within the Salinas River Watershed. The Salinas River Watershed covers appro ximately 4,600 square miles and is the Central Coast Region’s third‐largest watershed. There are two subwatersheds that make up the Salinas River Watershed: the Upper Salinas River and the Lower Salinas River. Both the IWTF and Airport Lift Station sites are located in the Lower Salinas River Subwatershed, which encompasses the area from north of Br
adley to Monterey Bay and is entirely within Monterey County. The Lower Salinas River Subwatershed is part of the larger Salinas Hydrologic Unit (HU). The Salinas HU is divided into Hydrologic Areas (HAs). The project area lies within the Salinas HU and the Lower Salinas Valley HA. The Salinas River HU in cludes the Monterey Peninsula and southern coastal area of Monterey Bay, the City of Salinas, agricultural and small urban centers of the Salinas Valley, and recreation developments in the upper watersheds.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐43 The Salinas River runs along the southern boundary of the IWTF and is the primary receiving water in the project area. The Salinas River system drains two major tributaries controlled by dams (i.e., Nacimiento River and San Antonio River).

Construction. Pollutants of concern during construction include sediment, trash, petroleum products, con crete waste (dry and wet), sanitary waste, and chemicals. Each of these pollutants on its own or in combination with other pollutants can have a detrimental effect on water quality.

During construction activities, excavated soil would be exposed, and there would be an increased potential for soil erosion and sedimentation co mpared to existing conditions. In addition, chemicals, liquid products, petroleum products (such as paints, solvents, and fuels), and concrete‐related waste may be spilled or leaked during construction. Any of these pollutants have the potential to be transported via storm water runoff into receiving waters.

Because the project would disturb greater than 1 ac re of soil, the project is subject to the requirements of the State Water Resources Control Board’s NPDES General Permit for Storm Water Discharge Associated with Construction and Land Disturbance Activities (Order No. 2009‐0009‐ DWQ, as amended by Order Nos. 2010‐0014‐DWQ and 2012‐0006‐DWQ, NPDES No. CAS0000 02) (Construction General Permit). Under the Construction General Permit, the Construction Contractor would be required to prepare a SWPPP and implement construction BMPs detailed in the SWPPP during construction activities. Construction BMPs would include, but not be limited to, erosion and sediment control, designed to minimize erosion and retain se diment on site, and good housekeeping practices to prevent spills, leaks, and discharge of construction debris and waste into receiving waters. In addition, the proposed project would be required to comply with the City of Salinas Standards to Control Excavations, Cuts, Fills, Clearing, Grading, Erosion and Sediments, as specified in Chapter 29, Stormwater M anagement and Discharge Control of the City of Salinas Municipal Code. Compliance with the requirements of the Construction General Permit and local regulations would ensure that the proposed project would result in less‐than‐significant impacts to water quality during construction.

The Airport Lift Station site is currently paved. Constr uction of proposed improvements at the Airport Lift Station would not require extensive ground‐disturbing activities; therefore, the Airport Lift Station improvements would not violate water quality standards or waste discharge requirements.

Operation. Development of the proposed project would not result in a significant increase in the amount of impervious surface area within the IWT F or Airport Lift Station project sites. Once constructed, proposed improvements would operate under the existing WDR. Adherence to the WDR would ensure that long‐term operation of the project would not violate any water quality standards or waste discharge requirements; therefore, the proposed project would not violate any water quali
ty standards or waste discharge requirements and impacts would be less than significant.

Would the project substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? (Less‐Than‐Significant Impact)
The proposed project is located within the Central Coast Hydrologic Region as defined by the California Department of Water Resourc es and the Central Coast RWQCB. The project sites are located within the 180/400‐Foot Aquifer Subbasin within the larger Salinas Valley Groundwater Basin. The Salinas Valley Groundwater Basin is identified as having the following beneficial uses in the Water Quality Control Plan for the Central Coastal Basin (Basin Plan): municipal and dome stic supply, agricultural supply, and industrial service supply.29 The 180/400‐Foot Aquifer Subbasin contains two main water‐bearing units that are the basis for the subbasin’s name—the 180‐Foot Aquifer and the 400‐Foot Aquifer—which are named for the average depth at which they occur. The thickness of the 180‐Foot Aquifer varies from 50 to 150 feet, with an average of 100 feet . The 180‐Foot Aquifer consists of a complex zone of interconnected sands, gravels, and clay lenses. The 180‐Foot Aquifer is separated from the 400‐Foot Aquifer by a zone of discontinuous aquifers and aquitards. The 400‐Foot Aquifer has an average thickness of 200 feet and consists of sands, gravels, and clay lenses.

Cons
truction. Temporary excavations for the IWTF improvements may extend to depths of 14 feet below ground surface. If groundwater is encountered during construction activities, groundwater dewatering may be required. If groundwater dewatering is required, water would be returned to one of the ex isting ponds on site and would not be discharged into any surface waters. Surface water discharges, if needed, would be conducted in accordance with the requirements of the SWRCB Statewide General Waste Discharge Requirements for Discharges to Land with a Low Threat to Water Quality (Water Quality Order No. 2003‐0003‐DWQ). This order requir es testing and treatment, as necessary, of groundwater extracted during construction prior to its release into surface waters to ensure that effluent limitations for constituents are not exceeded. As a result, groundwater dewatering during project construction would not introduce pollutants to receiving waters or violate water quality standard s or waste discharge requirements.

Operation. Project operation would not require groundwater extraction. However, implementation of the proposed project would result in a small increase in impervious surface area at the IWTF site.

An increase in impervious surface area decreases infiltration, which can decrease the amount of water that is able to re charge the aquifer/groundwater. However, because of the nominal change in impervious surface area, this decrease in infiltration would be minimal and would not interfere with groundwater recharge. Because the Airport LS site is currently paved, implementation of proposed improvements would not increase in impervious surface area at the Airport LS site. Therefore , operation of the project would result in a less‐than‐significant impact associated with depleting groundwater supplies or substantially interfering with groundwater recharge.

Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
i. Result in substantial erosion or siltation on‐ or off‐site; (Less Than Significant Impact) During constr
uction activities, soil would be exposed and disturbed, and drainage patterns would be temporarily altered during grading and other construction activities, resulting in an increased potential for soil erosion and siltation compared to existing conditions. Additionally, during a storm event, soil erosion could occur at an accelerated rate. As discussed in Se ction 3.10.a above, the Construction General Permit requires preparation of a SWPPP and implementation of construction BMPs to reduce impacts to water quality during construction, including those impacts associated with soil erosion and siltation. Therefore, adherence to the requirements of the Construction General Permit would ensu re that construction of the project would result in a less‐than‐significant impact associated with on‐ or off‐site erosion or siltation.

Implementation of proposed improvements would not result in a significant increase in impervious surface area or an associated increase in the volume and rate of runoff during a storm. Af ter installation of improvements, soils would be compacted and recovered to be consistent with current topography. Therefore, no significant change to the existing drainage pattern would occur resulting in on‐site or off‐site effects from erosion and siltation, and impacts would be less than significant. ii. Substantially increase th e rate or amount of surface runoff in a manner which would result in flooding on‐ or offsite; (Less Than Significant Impact) Construction activities would temporarily alter on‐site drainage patterns and compact soil, which can increase the volume and velocity of stormwater runoff. However, construction activities would be temporary, and the incr ease in runoff would not be substantial. As discussed in Section 3.10.a above, the Construction General Permit requires the preparation of a SWPPP to identify construction BMPs to be implemented as part of the project to reduce impacts to water quality during construction, including those impacts associated with flooding. Therefor e, adherence to the Construction General Permit would ensure that construction activities would not increase the rate or amount of surface runoff in a manner that would result in flooding on‐ or off‐site, and impacts would be less than significant.

Implementation of proposed improvements would not result in a significan t increase in impervious surface area or an associated increase in the volume and rate of runoff during a storm. No significant change to the existing drainage pattern would occur resulting in on‐site or off‐site flooding, and impacts would be less than significant.

g to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map No. 06053C0215G (April 2, 2009), most of the IWTF site is located within a 100‐year flood hazard zone (i.e., an area in which there is a 1 percent chance per year of a 100‐year storm event) and within the regulatory flo
odway and floodplain of the Salinas River. 30 The existing aeration lagoon is located in the 500‐year flood zone. The base flood elevations within the project area range from approximately 38 to 43 feet. The Airport LS site is not located within a designated special flood hazard area.31 Proposed improvements at the IWTF and Airport LS site would rehabilitate and/or replace existing infrastructure and construct limited new facilities within the existing boundaries of the IWTF and Airport LS site or within the adjacent public right‐of‐way. Proposed facilities would be similar to and consistent with existing facilities and wou ld not impede or redirect flood flows. This impact would be less than significant.
d. In flood hazard, tsunami, or seiche zones, would the project risk release of pollutants due to project inundation? (Less Than Significant Impact)
As described above, the majority of the IWTF site is located within a 100‐year flood hazard zone as mapped by FE
MA. Proposed improvements at the IWTF would rehabilitate and/or replace existing infrastructure and construct limited new facilities within the existing IWTF project site to enhance the efficiency and reliability of the existing system. The project site is currently subject to inundation, and implementation of the proposed project involves i mproving the efficiency and reliability of the existing system and would not alter or exacerbate the potential for release of pollutants due to inundation related to a 100‐year flood.

Seiching is a phenomenon that occurs when seismic groundshaking induces standing waves (seiches) inside water r etention facilities such as reservoirs and water tanks. Such waves can cause retention structures to fail and flood downstream properties. The water retention facilities closest to the proposed project are the San Antonio Dam, Lake San Antonio, the Nacimiento Dam, and Lake Nacimiento, which are located over 60 miles south of the project area. Due to the dista nce of the proposed project from the nearest water retention facilities, the proposed project is not at risk of

Tsunamis are generated wave trains generally caused by tectonic displacement of the seafloor associated with shallow earthquakes, seafloor landslides, rock falls, and exploding volcanic islands.

The project sites are no t located in a tsunami inundation area as identified by the California Department of Conservation (DOC) Tsunami Inundation Maps.32 Due to the distance of the proposed project from the ocean (approximately 6 miles) and its location outside any tsunami inundation areas, the proposed project is not at risk associated with possible inundation from a tsunami and there would not be an impact associated with the potential for release of pollutants due to inunda
tion.
e. Would the project conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? (Less Than Significant Impact) As discussed in Section 3.10.a. above, the proposed project would be subject to the requirements of the Construction General Permit during construction activities and the existi ng WDR during project operations. Adherence to the Construction General Permit and WDR would ensure that construction and long‐term operation of the proposed project would not violate any water quality standards or waste discharge requirements. Therefore, the proposed project would not conflict with the Basin Plan.

The California Sustainabl e Groundwater Management Act (SGMA), which took effect on January 1, 2015, established a framework of priorities and requirements to facilitate sustainable groundwater management throughout the State. The intent of SGMA is for groundwater to be managed by local public agencies (e.g., water districts and irrigation districts) and newly formed Groundwater Sustainabili
ty Agencies (GSAs) to ensure that a groundwater basin is operated within its sustainable yield (no long‐term overdraft) through the development and implementation of Groundwater Sustainability Plans (GSPs). The project sites are located within the 180/400‐ Foot Aquifer Subbasin for which the Monterey County Groundwater Sustainability Agency (Monterey County GSA) has adopted a GSP.

As describe
d above, groundwater dewatering may be required for the installation of the proposed improvements. Groundwater dewatering, if needed, would be temporary in nature and would cease following completion of construction. It is not anticipated that the volume of groundwater extracted during dewatering activities would be su bstantial in comparison to the overall volume of the groundwater basin. Additionally, the soils within the Salinas River have infiltration rates ranging from moderate to high, which would allow dewatered groundwater that is discharged back into the Salinas River to infiltrate and offset any localized groundwater depletion.

The proposed project wo uld rehabilitate and/or replace existing infrastructure and construct limited new facilities within the existing boundaries of the IWTF. The proposed project would not require

3.11.1 Discussion
a. Would the project physically divide an established community? (No Impact) The physical division of an established community typically refers to the construction of a physical feature (such as an interstate highway or railroad tracks) or removal of a means of access (such as a local road or bridge) that would impair mobili ty within an existing community, or between a community and outlying areas. Implementation of the proposed project would construct and replace facilities within the boundaries of the existing IWTF and underground/within public right‐of‐ way at the existing Airport LS site. Therefore, implementation of the proposed project would not physically divide an establi shed community. No impact would occur. b. Would the project cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? (Less Than Significant Impact)
The IWTF site is within the boundaries of the Gr eater Salinas Area Plan, which is part of the Monterey County General Plan. The Monterey County General Plan was adopted in 2010. The IWTF project site is currently designated as Public/Quasi‐Public in the Greater Salinas Area Land Use Plan.

The Public Quasi‐Public (PQP) land use designation accom modates publicly or privately owned uses such as schools, parks, regional parks, public works facilities, and hospitals that serve the public at large. The General Plan limits building coverage for this land use designation to 25 percent.

The IWTF site is zoned F/40 (Farmlands) and PQP (Public/Quasi‐Public). Monterey County Zoning Ordinan
ce Title 21 allows for “public utility uses” as an Allowable Use, subject to a Use Permit within areas that are zoned PQP (Section 21.40.050D). “Public and quasi‐public uses” are also an Allowable Use, subject to a Use Permit within areas that are zoned F/40 (Section 21.30.050B). As stated above, the proposed project would be impleme
nted within the existing IWTF site. Implementation of
proposed improvements within the IWTF site would not introduce a new or conflicting land use to the F/40 or PQP zone, and the proposed project would not conflict with the Monterey County General Plan. The proposed project is consistent with all applicable land use pl ans, policies, or regulations adopted, and no conflict/impacts would occur The Airport LS is located within the boundaries of the City of Salinas and is designated as General Industrial in the City of Salinas General Plan.

The primary mineral commodities mined in Monterey County include sand, gravel, and petroleum. The project area is not known to contain any economically valuable mineral resources. Therefore, the proposed project would not result in th e loss of availability of a known mineral resource that would be of value to the region and the residents of the State.

Would the project result in:

b. Generation of excessive groundborne vibration or
groundborne noise levels?
c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to exc essive noise levels?

3.13.1 Discussion
A project will normally have a significant effect on the environment related to noise if it would substantially increase the ambient noise levels for adjoining areas or conflict with the adopted noise policies and regulations of the community in which it is located. The IWTF is located south of the City of Salina s just west of Davis Road and north of the Salinas River in unincorporated Monterey County and the Airport LS is located at the south end of Airport Boulevard near Hansen Street in the City of Salinas. The lead agency is the City of Salinas; therefore, the applicable noise standards governing th
e project sites are the criteria in the City of Salinas General Plan Noise Element and Municipal Code.

Noise impacts can be described in three categories. The first is audible impacts that increase noise levels noticeable to humans. Audible increases in noise levels generally refer to a change of 3. 0 decibels (dB) or greater since this level has been found to be barely perceptible in exterior environments. The second category, potentially audible, is the change in the noise level between 1.0 and 3.0 dB. This range of noise levels has been found to be noticeable only in laboratory environments. The last cat egory is changes in noise level of less than 1.0 dB, which are inaudible to the human ear. Only audible changes in existing ambient or background noise levels are considered potentially significant. For the purpose of this analysis, the proposed project creates a significant noise impact if the project‐related noise increase at an exis ting sensitive receptor is greater than 3 dB and the resulting noise level is greater than the standards cited below or if the project‐related increase in noise is greater than 5 A‐weighted decibels (dBA), yet the resulting noise levels are within the applicable land use compatibility standards for the sensitive uses.

Would the project result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? (Less Than Significant Impact)
The following section des cribe the short‐term construction and long‐term operational noise impacts of the proposed project.

Short‐Term (Construction) Noise Impacts. Project construction would result in an increase in noise in the vicinity of the project sites. Maximum construction noise would be short‐term, generally intermittent depending on the construction phase, and variable depen ding on receiver distance from the active construction zone. The duration of noise impacts generally would be from one day to several days depending on the phase of construction. The levels and types of noise impacts that would occur during construction are described below.

Two types of short‐term noise impacts could o ccur during construction of the proposed project. The first type involves construction crew commutes and the transport of construction equipment and materials to the site for the proposed project, which would incrementally increase noise levels on roads leading to the site. As shown in Table 3.D, there would be a relatively hi gh single‐event noise exposure potential at a maximum level of 75 dBA maximum instantaneous noise level (Lmax) at 50 feet when a pickup truck passes during construction crew commutes.

The second type of short‐term noise impact is related to noise generated during excavation, grading, and construction on the project sites. Construction is performed in discrete steps, or phases, each with its own mix of equipment and, co nsequently, its own noise characteristics. These various (sequential phases would change the character of the noise generated on site. Therefore, the noise levels vary as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction‐ related noise ranges to be categoriz ed by work phase.

Table 3.D lists maximum noise levels recommended for noise impact assessments for typical construction equipment, based on a distance of 50 feet between the equipment and a noise receptor. Typical noise levels range up to 88 dBA Lmax at 50 feet during the noisiest construction phases. The site preparation phase, which includes excavation and grading of the project sites, tends to generate the highest noise levels because the noisiest construction equipment is earthmoving equipment. Earthmoving equipment includes excavating machinery such as backfillers, bulldozers, draglines, and front loaders. Earthmoving and co mpacting equipment includes compactors, scrapers, and graders. Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full‐power operation followed by 3 or 4 minutes at lower power settings.

Construction details (e.g., construction fleet activities) are not yet known; therefore, this analysis conservatively assumes th at scrapers, bulldozers, and water trucks/pickup trucks would be operating simultaneously during construction of the proposed project. As discussed above, noise levels associated with this equipment operating simultaneously would be approximately 88 dBA Lmax at 50 feet.

Certain land uses are considered more sensitive to noise than others. Examples of these include residential areas, educational facilities, hospitals, childcare facilities, and senior housing. The closest sensitive receptors to the IWTF project site include residential areas located approximately 2,500 feet north of the project site. The closest sensitive receptors to th e Airport LS site are approximately 2,800 feet north of the Airport LS site. Based on a reduction in noise of 6 dBA per doubling of distance, there would be a decrease of approximately 34 dBA from the active construction area to I NITIAL S TUDY /M ITIGATED N EGATIVE D ECLARATION N OVEMBER 2022

Therefore, the closest off‐site sensitive receptor may be subject to short‐ term construction noise reaching 54 dBA Lmax when construction is occurring.

Although the proposed project has the potential to increase noise levels associated with construction activities, as noted above, the increase would not exceed the existing noise environment and therefore would not expose sensitive receptors to noise levels in excess of City standards as established in Section 37‐50.180 of the City of Sali nas Municipal Code. Furthermore, construction activities would be temporary in nature and would be confined to daytime hours (e.g., 7:00 a.m. to 10:00 p.m.) as outlined in the City of Salinas Municipal Code Section 5‐12.03. Therefore, the impacts associated with construction noise would be less than signifi cant.

Operational Noise Impacts. A characteristic of sound is that a doubling of a noise source is required in order to result in a perceptible (3 dBA or greater) increase in the resulting noise level. The proposed project would implement improvements, which would include structural, mechanical, and electrical modifications within th e existing facilities and may require one additional employee. Given the nature of the changes, operational noise levels would be similar to existing ambient conditions and would not generate noise levels that would exceed the applicable standards. Therefore, the proposed project would not expose persons to noise levels in excess of local standards. Operational noise impa
cts would be less than significant.
b. Would the project result in generation of excessive groundborne vibration or groundborne noise levels? (Less Than Significant Impact)
Vibration refers to ground‐borne noise and perceptible motion. Ground‐borne vibration is almost exclusively a concern inside buildings and is rarely perc eived as a problem outdoors. Vibration energy propagates from a source, through intervening soil and rock layers, to the foundations of nearby buildings. The vibration then propagates from the foundation throughout the remainder of the structure. Building vibration may be perceived by the occupants as the motion of buil ding surfaces, rattling of items on shelves or hanging on walls, or as a low‐frequency rumbling noise. The rumbling noise is caused by the vibrating walls, floors, and ceilings radiating sound waves.

A significant vibration impact would occur if the project would expose persons to or generate excessive ground‐borne vibration or noi se levels. Common sources of ground‐borne vibration and noise include trains and construction activities such as blasting, pile driving and operating heavy earthmoving equipment. Construction of the proposed project would involve grading, site preparation, and construction activities including heavy earth moving equipment such as an excavator, bulldozer, and du mp trucks. Construction‐related ground‐borne vibration associated with this type of heavy equipment would have the potential to result in annoyance to residents and workers but would not cause any damage to buildings at 25 feet. The IWTF project site is not located within 25 feet of surrounding buildings; therefore, vibration would not be per ceptible, and residents and workers would not be exposed to vibration from construction activities. The Airport LS site is located in proximity to existing industrial buildings; however, construction activities for proposed improvements at the Airport LS would be limited and would not expose workers to vibration fr om construction activities. Additionally, operation of the proposed project would be the same as operation of the IWTF and Airport LS sites in the existing condition and would therefore not result in

c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a publi c airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? (Less Than Significant Impact)
The IWTF project site is not located within an airport land use plan, or within 2 miles of a public airport or pu
blic use airport. The closest airports to the IWTF site are the Salinas Municipal Airport, located approximately 7 miles northeast and the Marina Municipal Airport, located approximately

3.6 miles to the west of the IWTF site. The Airport Lift Station site is located just south of the Salinas Municipal Air
port; however, proposed improvements at the Airport Lift Station would include replacement of existing pumps within the underground lift station. As such, the proposed project would not expose people residing or working at the project sites to excessive noise levels, and impacts would be less than significant.

3.14.1 Discussion
a. Would the project induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? (No Impact)
The proposed project would implement improvements at the existing IWTF and Airport LS to provide operational and e fficiency improvements as well as capacity reliability and redundancy enhancements. The IWTF is bordered to the west and north by agricultural uses, to the south by the Salinas River, and to the east by Davis Road. The Airport LS is surrounded by industrial development.

Development of the proposed project would improve the reliabili ty and efficiency of the current system. The proposed project would not provide additional major infrastructure so as to encourage population growth or new development. Rather, the proposed project would address operational treatment efficiency and disposal capacity issues that are intended to provide sufficient capacity to handle existing uses an d planned agricultural industrial activities within the City of Salinas, as specified in the City’s General Plan. The proposed project would not include any new housing, commercial, or industrial facilities that would directly induce population growth. Therefore, the project would not directly or indirectly induce substantial population growth beyond what is already planned for in th
e City’s General Plan. No impact would occur.
b. Would the project displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? (No Impact) The proposed project would be constructed on City‐owned land within the boundaries of the IWTF site and within exis

i. Fire protection? (No Impact)
Fire protection and emergency medical services for the project area are provided by the Monterey County Regional Fire Protection District (MCRFPD).

The MCRFPD service area covers approximately 361 square miles, including rural areas surrounding the City of Salinas and east of the Cities of Marina and Seaside . The service area extends south past Carmel Valley and east to the community of Chualar. The MCRFPD provides ambulance services to the Carmel Valley residents. In the 2010 to 2011 fiscal year, 59 percent of the calls for service were medical emergency calls, totaling just ov er 1,200 calls. The MCRFPD participates in mutual aid throughout the State and maintains automatic aid agreements with all surrounding fire protection providers, including the City of Salinas and other local, State, and federal fire protection providers.

The IWTF is served by the Toro Station (Station 1), which is locate d at 19900 Portola Drive and is approximately 2 miles to the southeast of the IWTF site. The closest fire station to the Airport LS is Salinas Fire Department Station 3, located at 827 Abbot Place, approximately 0.75 mile from the Airport LS site.

The proposed project would not result in a substantial increase in the use of existing IWTF facilities or the number of employees (the proposed project would require one additional employee during project operations) servicing the facilities and would not include housing units or other structures th at would increase the population in the area or that would generate a higher demand for fire protection services. Therefore, the demand for fire protection services for the project would be the same as under existing conditions, and no impact would occur.
ii. Police protection? (No Impact)
Police protection in uni
ncorporated Monterey County is provided by the Monterey County Sheriff’s Office Enforcement Bureau‐Patrol Division (Patrol Division) and in the City of Salinas is provided by the City of Salinas Police Department.

The Patrol Division provides police protection and emergency‐related response services to a population of approximately 110,000 in dividuals located in unincorporated Monterey County and covers an area of 3,325 square miles. The Patrol Division operates out of three stations: the Central, Coastal, and South County Patrol Stations. The Central Patrol Station is the largest and busiest of the three stations and covers approximately 1,400 square miles and provid es police protection for the project area. The station is located at 1414 Natividad Road in Salinas, approximately 5 miles northeast of the existing IWTF and approximately 3.1 miles north of the Airport Lift Station.33 The City of Salinas Police Department operates out of a station at 312 East Alisal Street, approximately 1.5 miles from the Airport LS site. According to the Salinas Police Department’s Annual Report,34the Police Department has 143 full‐time sworn officers, and 39 full‐time civilian employees.

The proposed project would improve facilities at the existing IWTF and Airport LS and would not include housing units or other structures that would increase the population in the area or that would generate a higher dem and for police protection services. Therefore, the demand for police protection services for the project would be the same as under existing conditions, and no impact would occur.
iii. Schools? (No Impact)
The proposed project would improve facilities at the existing IWTF and Airport LS. The proposed project would require one additional em ployee during project operations and would not include housing units or other structures that would increase the population in the area and generate a higher demand for schools. Therefore, the demand for schools for the project would be the same as under existing conditions, and no impact would occur.

3.17.1 Discussion
a. Would the project conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? (Less Than Significant Impact)
The proposed project would implement improvements at the IWTF and the Airport LS sites.

Proposed improvements would include structural, mechanical, and electrical modifications within these existing City fa
cilities.

Construction of proposed improvements is anticipated to begin in July of 2023 and be completed by March 2026. During this period, temporary and intermittent transportation impacts would result from additional vehicle trips to the project sites from workers and equipment deliveries. However, improvements would only occur on the project sites and no i mprovements would occur at off‐site locations, such as roadway or intersection improvements. The vehicle trips associated with project construction would be limited and temporary, and therefore, would not impede normal traffic flows or circulation in the area, and would not conflict with a program, pl an, ordinance, or policy addressing the circulation system. There are no bicycle or pedestrian facilities on Davis Road in the vicinity of the IWTF site or on Airport Boulevard. Therefore, project construction would not conflict with a program, plan, ordinance, or policy addressing the circulation system, and impacts would be less than si gnificant.

Project operations would not alter current transportation uses or traffic volumes at the project sites.

Upon completion of construction, operation of the IWTF and Airport LS would be similar existing conditions. One additional employee may be required to operate proposed improvements, resulting in negligible additional vehicle trips for project operation. Because th e proposed project involves improvements to existing City facilities and would not permanently affect normal traffic flow or circulation at the project sites during project operations, operation of the proposed project would not conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pe destrian facilities, and impacts would be less than significant.

On December 28, 2018, the California Office of Administrative Law cleared the revised State CEQA Guidelines for use. Among the changes to the guidelines was removal of vehicle delay and level of service from consideration und
er CEQA. With the adopted guidelines, transportation impacts were required to be evaluated based on a project’s generation of vehicle miles traveled (VMT). In October 2020, the City of Salinas adopted the Interim Vehicle Miles Traveled (VMT) Policy35, for use in determining transportation impacts when a project is subject to CEQA. The Interim VMT Policy establishes screening criteria for land use projects that would not exceed an applicable threshold of significance. One of the screening criteria is for local essential services, including utilities. The Interim VMT Policy establishes that local essential se rvices (including public utilities) should be expected to cause a less‐than‐significant impact under CEQA and require no further VMT analysis.

As discussed above, the proposed project is anticipated to generate a low volume of traffic during construction and is not anticipated to result in additional vehicle tri ps associated with project operations once completed. In other words, upon completion of the project, the project will not generate any additional VMT. Because the proposed project would not produce additional VMT, the project meets the screening criteria identified in the City’s Interim VMT Policy and therefore, would neither conflict with nor be inconsistent with State CE QA Guidelines Section 15064.3, and the impact would be less than significant.
c. Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? (Less Than Significant Impact)
The proposed project would no t change the existing roadway design at the project sites. During construction phases, construction vehicles would be staged within an off‐roadway construction area. Additional heavy vehicles may travel along major arterials and freeways during construction.

Construction would not require lane closures and any temporary traffic control to allow construction machinery to access the pr oject sites would be consistent with those published in the California Temporary Traffic Control Handbook.36 Implementing measures contained within the California Temporary Traffic Control Handbook would facilitate safe passage of both construction vehicles and private vehicles. As a result, the proposed project would not substantially increase hazards for vehicles due to a design feature or incompatible uses. This impact would be less than significant.

The consultation provisions of the law r equire that a public agency consult with local Native American tribes that have requested placement on that agency’s notification list for CEQA projects.

Within 14 days of determining that a project application is complete or a decision by a public agency to undertake a project, the lead agency must notify tribes of the op portunity to consult on the project, should a tribe have previously requested to be on the agency’s notification list. California Native American tribes must be recognized by the NAHC as traditionally and culturally affiliated with the project site and must have previously requested that the lead agency notify the m of projects.

Tribes have 30 days following receipt of notification of a project to request consultation with the lead agency.

The purpose of consultation is to inform the lead agency in its identification and determination of the significance of tribal cultural resources. If a project is determined to result in a signifi cant impact on an identified tribal cultural resource, the consultation process must occur and conclude prior to adoption of a Negative Declaration or Mitigated Negative Declaration, or certification of an Environmental Impact Report (PRC Sections 21080.3.1, 21080.3.2, 21082.3).

As described in Section 1.0, Project Information, the City sent le tters describing the project and maps depicting the project site in September 2022 to all tribal representatives identified by the Native American Heritage Commission. A copy of the AB 52 letter is provided in Appendix B. To date, one tribal contact responded to confirm receipt of the notification; however, no requests for consultation have bee

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐69 Water Supply. During construction, water would be required primarily for dust suppression. Water use would cease when construction is complete. Sufficient water supplies are available to provide for the project’s minimal water needs during the construction phase of the project.

Water use for operation of the City’s industrial wastewater facilities would be the same as u nder existing conditions. Therefore, the proposed project would not require the construction of new or expanded water supply facilities or expansion of such facilities.

Wastewater. Proposed improvements would be constructed at the City’s existing IWTF and Airport LS sites, which are part of the City’s IWCCS. The IWC CS accepts flow from 23 agricultural processing facilities that are used for activities such as fresh produce washing and packaging operations.

Proposed improvements would enhance the efficiency of the existing facilities and enable the treatment facilities to more reliably accommodate wastewater treatment demand associated with the existing and planned industrial grow th within the City. As the IWCCS is separate from the City’s sanitary sewer system, the proposed project would have no impact on the City’s wastewater treatment system. Therefore, the project would not disrupt capacity to existing wastewater treatment users or demand an increase in wastewater treatment capacity to serve additiona l customers.

Implementation of the proposed project would not require or result in the relocation or construction of new or expanded wastewater treatment facilities.

Stormwater. Proposed improvements would create minimal impervious surfaces; the majority of the project sites would remain as they are in the existing condition. Therefore, changes to stormwater r
unoff would be negligible. Neither construction nor implementation of the proposed project would significantly affect the amount of on‐site runoff and therefore, would not require the expansion of stormwater facilities. No additional stormwater drainage facilities would be required.

This impact would be less than significant.

Gas, Electricity, and Telec ommunications. The proposed project would implement improvements to improve energy efficiency. Therefore, implementation of the proposed project would reduce the electricity demand at the project sites. No change to existing natural gas or telecommunications usage at any of the project sites are anticipated, as operation of proposed facilities would be similar to current operation. Ther
efore, the proposed project would not require or result in the relocation or construction of new or expanded gas, electricity, or telecommunications facilities, and no impact would occur.

The proposed project would not require or result in the relocation or construction of new or expanded water, wastewater tr eatment, or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects, and impacts would be less than significant.

Would the project have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? (Less Than Significant Impact)
The project would not result in an increase in the existing demand for water used by the existing facilities. New or expa nded water supply entitlements would not be required to serve the proposed project. The proposed project may require potable or reclaimed water for dust suppression during project construction. However, the amount of water required would be small and would only be needed during the construction period. Once complete, operation of the proposed project wou ld demand the same amount of water as under existing conditions. Therefore, the proposed project would have a less‐than‐significant impact related to water supplies. c. Would the project result in a determination by the wastewater treatment provider which serves or may serve the project that it ha s adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? (Less Than Significant Impact) Refer to Section 3.19.a above. Implementation of the proposed project would not result in a change in the demand for wastewater treatment. Impacts related to wastewater treatment would be less than significa
nt.
d. Would the project generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? (Less Than Significant Impact)
Project construction would generate wastes including construction materials, trench spoils, and general ref
use, and these wastes would need to be disposed of in local or regional facilities. Waste generated from construction could include: non‐hazardous metal waste, non‐hazardous non‐metal waste (i.e., concrete rubble, organic waste [vegetation], boxes and crates, refuse from construction workers), and trenching spoils (i.e., rubble, soils, broken asphal t).

The Johnson Canyon Sanitary Landfill is located in Gonzales (approximately 18 miles east of the project site). As of May 2021, the Johnson Canyon Sanitary Landfill had remaining capacity of 12.6 million cubic yards, with a maximum permitted capacity of 18.5 million cubic yards.37 The quantity of solid waste materials associated with construction would be small, limited to the construction period, and would not pose a significant impact upon existing landfills. No additional solid waste would be generated by long‐term operations of the proposed project. Impacts related to solid waste disposal would be less than signifi cant.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐71 e. Would the project comply with federal, state, and local management and reduction statutes and regulations related to solid waste? (Less Than Significant Impact) The California Integrated Waste Management Act (AB 939) changed the focus of solid waste management from landfill to diversion strategies such as source reduction, recycling, and composting
. The purpose of the diversion strategies is to reduce dependence on landfills for solid waste disposal. AB 939 established mandatory diversion goals of 25 percent by 1995 and 50 percent by 2000, and to maintain the 50 percent diversion rate thereafter. The Salinas Valley Solid Waste Authority (also known as Salinas Valley Recy cles [SVR]) is a joint powers agency made up of the following local governments: Monterey County (eastern half of the unincorporated County), and the cities of Gonzales, Greenfield, King City, Salinas, and Soledad. In 2008, the California Integrated Waste Management Board (now part of the DOC’s Division of Re cycling) updated the system for determining diversion goals for each city. At present, per capita landfill disposal limits are determined each year, and SVR works with its member jurisdictions to meet these goals.

As described in Section 3.19.d, implementation of the project would generate solid waste associated with construction activities. To the exte nt possible, solid waste would be recycled either on site or transported to a local disposal center for recycling. Solid waste generation would be limited to the construction period; no solid waste would be generated from long‐term operation of the proposed project. Because the proposed project would comply with federa l, State, and local statutes and regulations related to solid waste, proposed project impacts associated with solid waste would be less than significant.

If located in or near state responsibility areas or lands classified as very high fire hazard severity zones, would the project:

a. Substantially impair an adopted emergency response plan or emergency evacuation plan?
b. Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?

c. Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment?

d. Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post‐fire slope instability, or drainage changes?

3.20.1 Discussion
If located in or near state responsibility areas or lands classified as very high fire hazard severity zones:
a. Would the project substantially impair an adopted emergency response plan or emergency evacuation plan? (No Impact)
The IWTF site is located in an agricultural area and is not adjacent to urbanized areas or areas where residences are intermi
xed with wildlands. The Airport LS site is located in a highly urbanized area and is not adjacent to or intermixed with wildlands. The project sites are not located within any State responsibility areas for fire service and are not within a very high fire hazard severity zo ne (VHFHSZ).38 The proposed project would construct improvements within the existing IWTF and Airport LS sites. The proposed project would not change the existing roadway design within the project area. In the event of an emergency on the site, employees could exit the site via Davis Road, which provides access to Reservation Road and SR‐68 and Airport Boulevard, which provides a ccess to U.S. Highway 101 as they currently would under existing conditions. Therefore, in the event of a fire, the proposed project would not substantially impair the implementation of, or physically interfere with, an adopted emergency response plan, and no impact would o ccur.

P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Initial Study\Final Draft\Salinas IWTF_Final Draft ISMND.docx (11/17/22) 3‐73 b. Would the project, due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? (No Impact)
The IWTF project site is generally level and is bound by agricultural land and the Salinas Rive r. The Airport LS site is flat and is surrounded by urban development. Prevailing winds are typically from the west between March and October and from the north from October to March in the City of Salinas.

The proposed project would implement improvements that would be consistent with and similar in nature to the existi
ng facility. The proposed project would not include any design features that would increase the potential for a wildfire. Therefore, the proposed project would not exacerbate wildfire risks and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire, and no im pact would occur. c. Would the project require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? (No Impact) As discussed above, the pr oject sites are located outside of a VHFHSZ as identified by CAL FIRE. All proposed project components would be located within the boundaries of the project sites.

Therefore, the proposed project would not require the installation or maintenance of associated infrastructure that may exacerbate fire risk, and no im pact would occur. d. Would the project expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post‐fire slope instability, or drainage changes? (No Impact)
The proposed project is located on land that is relatively flat and is surrounded by land tha t is also relatively flat. Based on the location of the proposed project, which is outside of a VHFHSZ, and each sites’ flat topography, the susceptibility of the sites to downstream flooding or landslides associated with runoff from post‐fire slope instability or post‐fire drainage changes would be low. Theref ore, the proposed project would not expose people or structures to significant risks as a result of post‐ fire slope instability or drainage and runoff, and no impact would occur.

Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self‐sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or end angered plant or animal or eliminate important examples of the
major periods of California history or prehistory?

b. Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are
considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.)

c. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?

Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self‐sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the rang e of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? (Less Than Significant with Mitigation Incorporated)
As discussed in Section 3.4, Biological Resources, construction of the proposed Project has the potential to adversely impact migratory birds and raptors prot ected under the Migratory Bird Treaty Act (MBTA) during the nesting season. With implementation of Mitigation Measure BIO‐1, potential impacts to migratory birds and raptors would be reduced to less than significant levels. In addition, adjacent riparian areas could be indirectly impacted during construction activities, including from an increase or change in off‐si te runoff, erosion, noise/vibration, and spread of invasive species. To avoid or minimize indirect impacts during construction, Mitigation Measures BIO‐2 and BIO‐3 would be implemented to address proper erosion control and storage of construction equipment and the spread of invasive plant species. With implementation of Mitigati on Measures BIO‐2 and BIO‐3, impacts to sensitive natural communities would be less than significant.

As discussed in Section 3.5, Cultural Resources, the proposed project is not expected to result in any significant impacts to any examples of the major periods of California history or prehistory.

Subsurface archaeological testing was neg ative for the presence of prehistoric and historic‐period archaeological resources within the IWTF project site and no archaeological resources have been identified within or within 0.25‐mile of the Airport LS site. However, because the proposed project includes excavation, it has the potential to impact unknown buried archaeological resources and I NITIAL S TUDY /M ITIGATED N EGATIVE D ECLARATION N OVEMBER 2022

To avoid or minimize impacts to previously unidentified archaeological resources that may be determined significant per CEQA, archaeological monitoring of all ground‐disturbing project activities associated with the IWTF project site would be required, as specified in Mitigation Measure CUL‐1. In addition, in the eve nt that cultural materials are encountered during grading/construction at either the IWTF site or the Airport LS site, all work shall cease until the find has been evaluated and mitigation measures put in place for the disposition and protection of any find, as specified in Mitigation Measure CUL‐1. With impl ementation of Mitigation Measure CUL‐1, potential impacts to significant archaeological resources would be less than significant. Furthermore, if human remains are encountered during construction activities, the regulatory process outlined in Health and Safety Code (HSC) Section 7050.5 must be followed, which involves coordination with the Native Am erican Heritage Commission and a Native American Most Likely Descendant. Adherence to the HSC and Public Resources Code (PRC) Section 5097.98, which addresses the treatment of Native American human remains, means that the proposed project would not knowingly disturb human remains but would appropriately address any human remains should any be encountere d during project work.

With implementation of Mitigation Measures BIO‐1 through BIO‐3, and CUL‐1 and compliance with HSC Section 7050.5, the Project would not have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or a wildlife species, cause a fish or wildlife popul
ation to drop below self‐sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory.

Impacts would be less than signifi cant with mitigation incorporated. b. Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of proba ble future projects)? (Less Than Significant Impact) Section 15065(a)(3) of the State CEQA Guidelines states that a project’s cumulative impacts are the possible environmental effects that may be cumulatively considerable when considered with other reasonably foreseeable projects. Cumulatively considerable impacts occur when the incremental effects of a particular project or progra m are significant when viewed in connection with the effects of other past, current, or reasonably foreseeable future projects. Section 15355 of the State CEQA Guidelines defines a cumulative impact as an impact which is created as a result of the combination of the project evaluated in the CEQA document toget her with other projects causing related impacts. The proposed project is located within the boundaries of the existing IWTF and within public right‐of‐way. Other improvements proposed within the IWTF, including modifications to divert stormwater flows to the IWTF, could be implemented concurrently with the proposed project.

CEQA documentation has been prepare d for this specific project and identified no project‐level or cumulative impacts associated with implementation of the stormwater diversion project. As discussed above, environmental impacts associated with the proposed project can be reduced to less than significant through project‐specific mitigation or compliance measures. The impacts relevant to th e proposed project are localized and confined to the immediate project area. Given that the potential project‐related impacts would be less than significant and limited to a confined

No mitigation is required.
c. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? (Less Than Significant Impact) The proposed project includes implementation of improvements to the City’s industrial wastewater treatment system to provi de operational and efficiency improvements as well as capacity reliability and redundancy enhancements for the industrial users. As demonstrated throughout this environmental document, impacts associated with the proposed project including those that may have a direct or indirect adverse effect on humans, can be reduced to less than significant thro ugh project‐specific mitigation or regulatory compliance measures. The proposed project would not result in environmental effects which would cause a substantial direct or indirect adverse effect on human beings.

SALINAS INDUSTRIAL WASTEWATER TREATMENT FACILITY
IMPROVEMENTS PROJECT
For the purposes of the SRF application, the City is obligated to look at other alternatives that could be implemented in lieu of the proposed project. Alternatives considered are as follows:
 Alternative 1: No Action. Under this alternative, no improvements would be implemented and the City’s industrial wastewater treatment system wou ld continue to operate as it does under existing conditions.
 Alternative 2: New Aeration Lagoon in Pond 1. This alternative would provide additional treatment capacity by building up a berm for a new aeration lagoon in Pond 1. This alternative would require construction of a new berm at an elevation above the floodplain due to Fe deral Emergency Management Agency (FEMA) requirements. It would also necessitate a permit from the Division of Safety of Dams (DSOD).
 Alternative 3: New Aeration Lagoon on Ag Land adjacent to the IWTF. This alternative would provide additional treatment capacity by building a new aeration lagoon on adjacent proper ty.

This alternative would require acquisition of land from private property owners.  Alternative 4: New percolation ponds in Ag Land adjacent to the IWTF. This alternative would provide additional disposal capacity by creating new percolation ponds in lieu of transferring treated water to M1W RTP for reuse. Th is alternative would also require acquisition of land from private property owners.
 Alternative 5: Proposed Project. This alternative would implement improvements at the City’s existing Industrial Wastewater Treatment Facility (IWTF) and Airport Lift Station. This alternative is comprised of four project components: (1) the Aeration Lagoon Improvements Project; (2) the Pond Automa
tion/Distribution and Pond 3 Pump Station Project; (3) the Variable Frequency Drives (VFDs) and Backup Power Project; and (4) the Airport Lift Station Project.

Each of the above project alternatives results in varying temporary and permanent environmental impacts, which are compared in the attached table. When alternatives have dif fering impacts, the alternative with less impact is marked with a (+) to indicate it is the preferred alternative.

Alternative 1, No Action, was not selected because it would not provide capacity reliability and redundancy and operational and efficiency improvements for existing and planned future agricultural industrial users.

Alternative 2, New Aerati on Lagoon in Pond 1, would have roughly the same project footprint as Alternative 5, Proposed Project because all of the proposed improvements associated with Alternative 2 at the IWTF site would be constructed within the existing IWTF boundaries. However, Alternative 2 would include additional construction activities within Pond 1 to provide for a new aeration lago
on. Alternative 2 would have the potential to result in temporary air quality emissions

It would also necessitate a permit from the Division of Safety of Dams (DSOD).

Both Alternative 3, New Aeration Lagoon on Ag Land adjacent to the IWTF, and Alternative 4, New Percol
ation ponds in Ag Land adjacent to the IWTF, would have a larger footprint than Alternative 5, Proposed Project, because they would include not only the components of Alternative 5, but the acquisition and construction of additional facilities on existing, private agricultural land adjacent to the IWTF
. Both of these alternatives would result in the permanent conversion of agricultural land designated as Prime Farmland1 by the California Department of Conservation. In addition, these alternatives would require more ground disturbance during construction, resulting in the potential for impacts to previously unidentified cultural and paleontological resources, air emissions, and greenhouse gas emissions.

Alternative 5, the Proposed Project, was selected over Alternatives 2, 3, and 4 because it ha s fewer environmental impacts, is less expensive, impacts less land, and would require fewer regulatory permits. All identified impacts that may result from Alternative 5 would be reduced to less than significant by incorporating the mitigation measure identified in the Initial Study/Mitigated Negative Declaration.

Subject: Project Notification and Invitation to Consult under Assembly Bill 52 for the Salinas Industrial Wastewater Treatment Facility Improvements Project in Salinas, Monterey County, California

Please consider this letter as formal notification of a proposed project as required under the California Environmental Quality Act, specifically Public Resources Code (PRC) Section 21080.3.1 and Chapter 532 Statutes of 2014 (i.e., Assembly Bill [AB] 52). Pursuant to PRC Section 21080.3.1(d), please respond in writing within 30 days from receipt of this letter if you would like to consult on this project. If you do not wish to consult for the proposed project, a written response indicating your declination to consult would be appreciated. Please provide a designated lead contact person if you have not provided that information to us already.

The City of Salinas (City) is proposing to implement improvements to its industrial waste treatment system that treats wastewater from local agriculture-based industries. The proposed improvements would be constructed at the City’s existing Industrial Wastewater Treatment Facility (IWTF), which is part of the City’s Industrial Wastewater Collection and Conveyance System (IWCCS). The IWCCS, which is separate from the City’s sanitary and storm sewer systems, accepts flow from 23 different facilities that are primarily for agricultural processing, such as fresh produce washing and packaging operations. The wastewater is conveyed to the IWTF for disposal or recycling. The IWTF is located south of the City of Salinas just west of Davis Road and north of the Salinas River in unincorporated Monterey County. The proposed project would also include improvements to the Airport Lift Station, located at the south end of Airport Boulevard near Hansen Street in the City of Salinas. (Please see the enclosed figures for project locations). Proposed improvements at the IWTF and Airport Lift Station would provide operational and efficiency improvements as well as capacity reliability and redundancy enhancements for the industrial users.

A search of the Sacred Lands Files conducted by the Native American Heritage Commission was positive for the presence of tribal cultural resources within the project site and your tribe was identified to be contacted for additional information.

If you have any questions or concerns about the project, please contact me via email at [email protected] or by phone at (831) 758-7241.

Subject: Biological Resources Assessment for the Salinas Industrial Wastewater Treatment Facility Improvements Project located in the City of Salinas and unincorporated Monterey County, California
Dear Mr. Frus:

The purpose of this Biological Resources Technical Memorandum is to describe and document potential impacts to biological resources associated with the proposed Salinas Industrial Wastewater Treatment Facility Improvements Project (project) in the City of Salinas and unincorporated Monterey County, California (refer to Figure 1; all figures are provided in Attachment B). This technical information is provided for project review under the California Environmental Quality Act (CEQA) and the Environmental Review Process Requirements for the State Water Resources Control Board’s Clean Water State Revolving Fund Program (April 2017). This document provides a biological resources impact analysis that reflects the current environmental setting, project design, and regulatory context.

PROJECT SITES AND SETTING
The project involves proposed improvements at two distinct sites: one site is located within the unincorporated portion of Monterey County (the Industrial Wastewater Treatment Facility) and the other site is located within the City (the airport lift station) (see Figures 1 and 2, Attachment B). The Industrial Wastewater Treatment Facility (IWTF) is located just west of Davis Road, north of the Salinas River, hereinafter referred to as the “IWTF Project Site” (Figure 3). The Airport Lift Station is located in the southeast portion of the City at the south end of Airport Boulevard near Hansen Street (Figure 4).

The project sites are locate
d in Ranges 2 and 3 East, Township 15 South on the 7.5‐minute series United States Geological Survey (USGS) Salinas, California quadrangle. The “project sites” discussed in this memorandum refer to all areas where direct, physical construction‐related disturbance would occur. The Biological Study Areas (BSAs) for the project sites inc lude the direct project disturbance limits plus a buffer of up to 300 feet to account for indirect project‐related effects such as noise and vibration.

The IWTF project site is located adjacent to the floodplain of the Salinas River. The IWTF project site is currently developed with wastewater treatment po nds and associated infrastructure (i.e., pipelines, surface aerators, and pump houses, etc.). Other vegetation and land cover types in the IWTF BSA include agriculture, detention basins, an irrigation canal, disturbed/barren areas, ruderal areas, and riparian woodland associated with the Salinas River (located to the south/southwest of

Extensive soil disturbance from vehicles is evident throughout the IWTF BSA, and portions of the IWTF appear to be regularly disked for vegetation control.

The Airport Lift Station BSA is currently developed and surrounded by commercial/industrial developments in the City of Salinas. Portions of the Airport Lift Station BSA support ruderal areas and ornamental vege
tation.

The BSAs are located within the Central Coast region of the California Floristic Province (Baldwin, et al. 2012) and within the Alisal Creek‐Salinas River watershed (Hydrologic Unit Code #180600051509). The BSAs are relatively flat with almost no topographic variation and are at approximately 26
to 40 feet above mean sea level. Overall, both BSAs are subject to regular anthropogenic disturbance associated with the operations of the existing facilities (i.e., vegetation clearing, facility maintenance, etc.).

Proposed Project
The City of Salinas (City) is proposing to implement improvements to its industrial wastewater treatment system that treats wastewater from local agriculture‐based industries. The proposed improvements would be constructed at the City’s existing Industrial Wastewater Treatment Facility (IWTF), which is part of the City’s Industrial Wastewater Collection and Conveyance System (IWCCS).

The IWCCS, which is separate from the City’s sanitary and storm sew er systems, accepts flow from
23 different agricultural facilities that are primarily for agricultural processing, such as fresh produce washing and packaging operations. The wastewater is conveyed from the agricultural facilities to the IWTF for disposal or recycling. Proposed improvements at the IWTF and Airport Li ft Station would provide operational and efficiency improvements as well as capacity reliability and redundancy enhancements for the industrial users. The City intends to seek State Revolving Fund (SRF) funding for these improvements.

Project Components
The Industrial Waste Treatment Facility Improvements Project (proposed project) includes the following four Capital Improvement Plan (CIP) projects identified in the Industrial Wastewater System Analysis and Revised Rate and Connection Fee Study: (1) the Aeration Lagoon Improvements Package, (2) the Pond Automation/Distribution and Pond 3 Pump Station Package, (3) the VFDs and Backup Power Package, and (4) the Airport Lift Station Package. It is not yet cle ar whether the four
projects would be packaged under a single contract or delivered separately. A map of the IWTF and IWCCS facilities is shown on Figures 1 and 2, with the project areas highlighted. The major elements of each project componen
t are described below:

Aeration Lagoon Improvements. The existing Aeration Lagoon has twelve 50‐horsepower (hp) surface aerators installed. The Aeration Lagoon Improvements Project involves replacing four of these aerators with new units of the same capacity as the existing aerators, because the existing units have exceeded their useful desig n life. An additional three 50‐hp aerators would be installed in the existing lagoon to provide additional treatment capacity. Proposed improvements would also include upgrades to existing electrical and communications systems – including running new electrical wiring, new motor control centers, a new electrical building(s), and new transforme rs. An area of the lagoon berm would be widened to accommodate a new electrical building and

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 3 equipment. The new Electrical/Control Building is expected to have a footprint of 12 feet by 18 feet by 10 feet high.

Pond Automation/Distribution and Pond 3 Pump Station. Proposed improvements would include upgrades to provide additional control and automation to enhance flow monitoring and operation, including a new concrete structure and access for flow and water le vel monitoring equipment, piping/valves, water level controls, slide gates and electrical and instrumentation upgrades. New piping would be provided between ponds and would be buried in the existing berms. New pump stations (with either permanent or portable pumping units) would be provided in each pond to facilitate transfer
of water between ponds. Sheet piles or internal berms would be constructed within the existing percolation ponds to facilitate operation and maintenance of the ponds.

The Pond 3 Pump Station upgrades would include the addition of a new second pump with the same capacity as the existing pump to enhance pumping r eliability.

Variable Frequency Drives (VFDs) and Backup Power. This project improvement would add new VFDs on the existing and new aerators to provide better control and operational cost savings by reducing energy usage at appropriate times of day or seasons. VFDs would be installed in an electrical control building in the Aeration Lagoon area, on the berm
s adjacent to existing electrical equipment.

The Backup Power project element would include the addition of three fixed standby emergency generators capable of generating a total of 1.5 megawatts (MW) of power to increase facility reliability/resiliency and to ensure uninterrupted wastewater conveyance and tr eatment in the event of power outages. Emergency generators would be installed adjacent to the IWTF influent pump station and an Aeration Lagoon substation with other electrical equipment.

Airport Lift Station. The Airport Lift Station project would increase the current firm capacity of the pump station from 4 million gallons per day (mgd) to 6 mgd peak flow to ad equately serve the existing industrial users that discharge to this pump station. Proposed improvements would include either replacing the existing pumps or expanding the lift station to incorporate new pumps to provide the increased capacity.

METHODS
Literature Review and Records Search
LSA Biologist Kelly McDonald conducted a literature review and records search on August 11, 2022, to identify the existence and potential for occurrence of sensitive or special‐status plant and animal species1 in the project vicinity. Federal and State lists of sensitive species were also examined.

1 For the purposes of this report, the term “special‐status species” refers to those species that are listed or proposed for listing under the California Endangered Species Act (CESA) and/or the Federal Endangered Species Act (FESA), California Fully Protected Species, and California Species of Special Concern. It should be noted that “Species of Sp ecial Concern” is an administrative designation made by the CDFW and carries no formal legal protection status. However, Section 15380 of the State CEQA Guidelines indicates that these species should be included in an analysis of project impacts if they can be shown to meet the criteria of sensitivity outlined therein.

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 4 Current electronic database records reviewed included the following:
 California Natural Diversity Data Base information (CNDDB – RareFind 5), which is administered by the California Department of Fish and Wildlife (CDFW), formerly known as the California Department of Fish and Game. This database covers sensitive plant and animal species, as well as sensitive natural communities that occur in California. Records from nine USGS quadrangles surrounding the project area (Marina, Salinas, Natividad, Seaside, Spreckels, Chualar, Moss Landing, Prunedale, and San Juan Bautista), along with a query of records within a 5‐mile radius of the project sites, were obtained from this database to infor m the field survey.  California Native Plant Society’s (CNPS) Electronic Inventory of Rare and Endangered Vascular Plants, which uses four specific categories or “lists” of sensitive plant species to assist with the conservation of rare or endangered botanical resources. Records from the nine USGS quadrangles surrounding the project areas were obtained from this database to inform the field survey.
 United States Fish and Wildlife Service’s (USFWS) Information for Planning and Conservation (IPaC) Online System, which lists all proposed, candidate, threatened, and endangered species managed by the Endangered Species Program of the USFWS that have the potential to occur on or near a particular
site. This database also lists all designated critical habitats, national wildlife refuges, and migratory birds that could potentially be impacted by activities from a proposed project. An IPaC Trust Resource Report (USFWS 2022a) was generated for the project sites.  Designated and Proposed USFWS Critical Habi tat Polygons were reviewed to determine whether critical habitat has been designated or proposed within or in the vicinity of the project sites (USFWS 2022b).
 The USFWS National Wetlands Inventory was reviewed to determine whether any wetlands or surface waters of the United States have been previously identified in th e project sites (USFWS 2022c).
 eBird: eBird is a real‐time, online checklist program launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society. It provides rich data sources for basic information on bird abundance and distribution at a variety of spatial and temporal scales. eBird occurrence records within th
e project sites and a 5‐mile radius around the project sites were reviewed in August (eBird 2022).

In addition to the databases listed above, historic and current aerial imagery, and local land use policies related to biological resources were reviewed.

Field Survey
LSA Biologist Kelly McDonald conducted a general biological survey of the IWTF and Airport Lift Station BSAs on August 12, 2022, to document existing site conditions and the potential presence of sensitive biological resources. The project sites were surveyed on foot, and all plant and animal species observed were recorded. Suitable habitat for any species of interest or concern was duly noted, and general site conditions were photographed (see Attachment C). The field survey took

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 5 place on a clear sunny morning with weather conditions conducive to the detection of plant and animal species.

RESULTS
Vegetation
At the time of the field survey, the IWTF BSA contained wastewater treatment ponds and associated infrastructure (mapped as developed areas), an irrigation canal, cultivated and tilled agricultural fields, a detention basin, disturbed/barren areas, and ruderal (e.g., disturbed, weedy) patches of mostly nonnative/invasive herbaceous plant species. Riparian woodland associated with the Salinas River is presen
t in the southern portions of the IWTF BSA. The Airport Lift BSA is primarily developed and contains several small patches of ruderal and ornamental vegetation. Figures 5 and 6 (Attachment B) show vegetation and land cover types mapped in the BSAs. The acreages of each vegetation community and land cover ty pe occurring within the BSAs are shown in Tables A and B, below.

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 6 A total of 47 vascular plant species were identified within both BSAs during the August 2022 field survey. See Attachment D for a complete list of species identified on the BSAs. The following describes the vegetation and land cover types occurring within the two BSAs:
 Detention Basin: The detention basin is an area that was excavated in uplands and desig ned as an overflow or emergency basin to prevent flooding and erosion from a pump house located within the agricultural fields outside of the IWTF project site.  Ornamental: Ornamental areas consist of introduced trees, shrubs, and flowers, with turf grass and other nonnative
grasses commonly occurring in the understory. Ornamental landscaping is vegetation that is typically planted and maintained within and adjacent to developed areas.  Tilled Agricultural Land: Tilled agricultural land is a previously cultivated area that has been recently tilled and no live vegetation was present in this area at the ti me of field survey.  Irrigation Canal: This is a constructed canal that carries stormwater and agricultural runoff from the adjacent agricultural properties to the Salinas River. Portions of the irrigation canal contain wetland indicator plant species such as cattails (Typha sp.), horsetail (Equisetum sp.), California bulrush (Schoenopl ectus californicus), and nut grass (Cyperus esculentus). The irrigation canal has culverts in two locations (Culvert 3 and 4) that direct surface flows to the Salinas River, making these features potential jurisdictional waters of the State and water of the United States. Culverts 1 and 2 provide a connection to ot her portions of the canal due to breaks in the canal.
 Open Water: Areas mapped under this classification include actively flowing water between the banks of the Salinas River.
 Developed: Developed sites consist of paved areas, buildings/structures, and other areas that are cleared or graded for anthropogenic purposes.
 Disturbed/Barren: Distur
bed/barren areas lack vegetation and contain bare ground or crushed gravel at the time of the survey. Sparse cover of ruderal vegetation is present in portions of these areas with black mustard (Brassica nigra) being the most commonly observed. Several other invasive, pioneering plant species are also present in these areas at low cover.  Riparian Woodland: This area contains a mi
xed canopy of black cottonwood (Populus
trichocarpa), box elder (Acer negundo), arroyo willow (Salix lasiolepis), narrow leafed willow (Salix exigua), and red willow (Salix laevigata). The understory contains California mugwort (Artemisia douglasi ana) and stinging nettle (Urtica dioica), among others. Several nonnative grasses are present in the understory including brome grasses (Bromus sp.) and annual beard grass (Polypogon monspeliensis).
 Agriculture: Areas mapped as agriculture consist of active crops such as a variety of vegetables, lettuce, and strawberries.
 Ruderal: Areas classified as ruderal consist of early s uccessional grassland dominated by pioneering herbaceous plants that readily colonize disturbed ground. Ruderal plants dominant

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 7 within this area include weedy or pioneering species such as black mustard and brome grasses.

These areas appear to have been cleared and/or graded for anthropogenetic purposes in the recent past.
 Wastewater Treatment Ponds: The four ponds are associated with the IWTF and were artificially constructed for the treatment of industrial wastewater. These ponds are treated and routinely maintained.

Wildlife
A total of 38 wildlife species were observed on or near the BSAs during the August 2022 survey.

Frequently observed species included barn swallow (Hirundo rustica), mallard (Anas platyrhynchos), and great blue heron (Ardea herodias). Each of the 38 species observed commonly occur in and around the Salinas River watershed. A list of wildlife species observed can be found in Attachment D.

Resident and migratory bird species utilize the IWTF BSA for foraging. Flocks of migratory waterfowl are routinely documented at the IWTF wastewater treatment ponds (eBird 2022), as are colonial nesting species such as cliff swallows (Petrochelidon pyrrhonota).

Special‐Status Natural Communities
The CNDDB search identified occurrences of seven special‐status natural (i.e., plant) communities within the nine‐quadrangle search area: Central Dune Scrub, Central Maritime Chaparral, Coastal and Valley Freshwater Marsh, Coastal Brackish Marsh, Monterey Pine Forest, Northern Coastal Salt Marsh, and Valley Needlegrass Grassland2. All seven of these special‐status natural communities are absent from the BSAs. One natural community protected under the California Fish and Game Code, riparian woodland, was mapped along the southern portion of the IWTF BSA near the Salinas River.

There are no special‐status natural communities within the IWTF project site. No sensitive na tural communities are located within the Airport Lift Station BSA.

Special‐Status Plants
Attachment E contains tables that identify special‐status species known to occur or that potentially occur in the vicinity of the BSAs and include detailed information about each species’ habitat and distribution, activity period, listing/status designations, and probability of occurrence within the project site boundaries. These species were compiled from the CNPS, the CNDDB, and IPaC records searches from a 5‐mile radius around the project site and from LSA’s extensive knowledge and experience in the region.

The literature review identified 47 special‐status plant species that are known to occur within a nine‐quadrangle radius of the BSAs. The majority of the rare plan t species that were identified in the

2 The CNDDB uses sensitive vegetation community names described in the Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986). No new sensitive natural community records have been added to the CNDDB since the 1990s. Therefore, natural communities mapped by the CNDDB are limited.

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 8 databases have specialized habitat requirements (i.e., wetland habitats, dunes, vernal pools, etc.) that do not occur within the project sites or BSAs.

The project sites are extensively disturbed, developed, and routinely maintained. Such anthropogenic disturbances have greatly altered the natural hydrologic regimes and have either eliminated or greatly impacted the pre‐settlement ha bitats needed to support the special‐status plant species identified in the CNDDB and CNPS queries. As such, the specific habitats, soil substrates, or “micro‐climates” necessary for special‐status plant species to occur are absent within the boundaries of the project sites. Based on site observations coupled with the habitat suitability analysis, no special‐status plant species are expected to occur within the project sites. It is also unlikely that any source populations exist in adjacent or nearby parcels that could be indirectly affected by project‐related activities.

Special‐Status Animals
The historic anthropogenic disturbances and disturbed, developed nature of the project sites and adjacent parcels (i.e., farming, disking, etc.) have greatly altered, eliminated, or impacted the pre‐ settlement habitats needed to support most of the special‐status animal species identified in the CNDDB and USFWS queries. The literature review identified 49 special‐status animal spe cies that are known to occur within a nine‐quad radius of the BSAs. Of those 49, 22 special‐status animal species have documented CNDDB records within a five‐mile radius of the BSAs (refer to Attachment E). One special‐status animal species, Monterey hitch (Lavinia exilicauda harengus), has bee n documented in the Salinas River in areas adjacent to the IWTF. No special‐status animal species have been documented within the Airport Lift Station BSA. No special‐status animal species or signs of such species were observed within the Airport Lift Station or the IWTF project site (see subsections below).

Aquatic
Species
As noted above, the Monterey hitch has been documented in the Salinas River in areas adjacent to the IWTF. However, the Monterey hitch is not expected to occur within the IWTF project site. The wastewater treatment ponds are treated and routinely maintained, and the irrigation canal does not contain permanent water or the substrate necessary for spawning . Therefore, the IWTF project site
is not expected to support Monterey hitch.

Similarly, western pond turtle (Emys marmorata) and California red‐legged frog (Rana draytonii) require permanent aquatic habitat, but the maintained nature and controlled hydrologic regime of the irrigation canal and wastewater trea
tment ponds does not provide suitable habitat for these species. Therefore, western pond turtle and California red‐legged frog are not expected to occur within the IWTF project site. Species such as western spadefoot (Spea hammondii), California tiger salamander (Ambystoma californiense), and California linderiella (Linderi ella occidentalis) require temporary pools and habitat characteristics that are not present within the IWTF project site.

Tricolored blackbird (Agelaius tricolor) may forage/migrate over and around the IWTF project site, but colonial nesting habitat is absent from the project site.

The Airport Lift Station project site does not contain an y aquatic habitat and is not expected to support any aquatic special‐status animal species.

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 9 Annual Grassland Species
The IWTF BSA does not contain any annual grassland habitat that would support northern California legless lizard (Anniella pulchra), coast horned lizard (Phrynosoma blainvillii), or American badger (Taxidea taxus). Additionally, the soils are too dry and compact from longstanding wastewater treatment operations to provide preferred soil conditions for these species. Ther efore, northern California legless lizard, coast horned lizard, and American badger are not expected to occur within the IWTF project site.

No food genera or suitable roosting/nesting habitat used by special‐status bumblebees (Bombus spp.), Smith’s blue butterfly (Euphilotes enoptes smithi), or monarch (Danaus pl exippus plexippus) were observed within the IWTF project site. While it is possible for such insects to pass through the IWTF BSA, habitat features required for the recovery of these species are not present within the IWTF project site.

The Airport Lift Station project site and BSA do not contain any annual grassland habitat and are not expected to support the special‐status animal species listed above.

Roosting Bats
Bat species such as pallid bat (Antrozous pallidus), Townsend’s big‐eared bat (Corynorhinus townsendii), and hoary bat (Lasiurus cinereus) may forage over and around the IWTF project site, but there is no suitable ro
osting habitat present within the IWTF project site limits. Tree‐roosting bat species may roost in the riparian woodland habitat along the Salinas River, outside of the project disturbance limits. The Airport Lift Station project site and BSA do not contain any suitable roosting habitat.

Nesting Birds
No suitable burrowing owl (Athene cunicularia) burrows were observed within the IW TF project site
making nesting unlikely to occur. However, some suitable foraging habitat is present within the ruderal areas of the project site and open agricultural areas in the surrounding BSA.

Suitable foraging habitat and nesting habitat for grou nd‐nesting species such as California horned lark (Eremophila alpestris actia) are present within the IWTF project site. According to eBird, this species was observed within the IWTF project site in August 2022.

The IWTF project site also contains suitable foraging habitat for certain raptors such as Swainson’s hawk (Buteo swainsoni), w
hite‐tailed kite (Elanus leucurus), and Cooper’s hawk (Accipiter cooperii), but nesting is not expected within the IWTF site itself. There are no trees or shrubs present within the IWTF project site that could be used for nesting by raptors, although suitable nesting habitat is present along the Salinas River. Several eBird records docu mented Swainson’s hawk foraging over
the IWTF project site and surrounding lands in 2008, 2011, and 2013.

Several raptor species that are afforded specific protection under the California Fish and Game Code were observed flying over and around the IWTF project site during the August 2022 field survey, including red‐tailed hawk (Buteo jamaicensis). Peregrine falcon (Falco mexicanus) and golden eagle (Aquila chrysaetos) could forage over or within the IWTF BSA, but nesting habitat is absent in the

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 10 project site due to the lack of cliffs, large rock outcrops, or tall buildings. Suitable avian nesting habitat in the IWTF project site is limited to that which supports ground‐nesting species such as killdeer (Charadrius vociferous) and other birds that may nest in the annual herbaceous cover.

Additionally, nesting cliff swallows were observed on the pump house duri ng the August 2022 field survey, and nesting swallow colonies have been documented in the past at the IWTF site by multiple eBird contributors (eBird 2022).

The Airport Lift Station project site and BSA contain limited ornamental vegetation that provides only marginally suitable nesting habitat for most bird species.

Wetlands and Potential Jurisdictional Aquatic Resources An irrigation canal and wastewater treatment ponds are located within the IWTF project site, and the Salinas River is located within the IWTF BSA. No aquatic features are located within the Airport Lift Station BSA.

The Salinas River is located along the southwestern portions of the IWTF BSA. Hydrophytic plants and riparian vegetation wer e observed along the bank such as arroyo willow, red willow, narrow leafed willow, box elder, and black cottonwoods. The Salinas River contains a defined bed/bank and an ordinary high‐water mark. The Salinas River originates in the Los Padres National Forest and flows in a north‐northwest direction wher e it drains into the Pacific Ocean, a traditionally navigable water. As such, the Salinas River is a jurisdictional water of the United States and water of the State, subject to United States Army Corps of Engineers (USACE) and Central Coast Regional Water Quality Control Board (RWQCB) regulation, respectively. Riparian vegetation associated with the Salinas River is also subject to CDFW and RWQCB regulation.

An irrigation canal is located in the IWTF BSA along the edges of the drying beds and wastewater treatment ponds. Surrounding agricultural operations contribute water to the canal, with one inlet observed in the northernmost corner of the BSA and several other drains along the canal. The irrigation canal flows into the Salinas River through two culverts, as shown on Figure 5. The canal was dry at the time of the survey, but soil cracks were present in portions of the canal. Furthermore, portions of the canal support ca ttails and other hydrophytic (e.g., wetland indicator) plant species such as horsetail, California bulrush, and nut grass. Other areas of canal lacked vegetation and were comprised of sparse ruderal/nonnative vegetation like black mustard.

Because the irrigation canal exhibits an ordinary high water mark and connects to the Salinas River, a jurisdictional water of the United St ates, the irrigation canal meets the current regulatory definition of waters of the United States subject to USACE jurisdiction under the federal Clean Water Act. Any discharge of fill or waste material within the canal would also be subject to regulation by the RWQCB as waters of the Sta te. Physical ground or vegetation disturbance within the irrigation canal banks would also be subject to CDFW jurisdiction under Section 1602 of the California Fish and Game Code.

Four wastewater treatment ponds are located within the IWTF project site. These ponds are artificially constructed and are regularly maintained and treated for wastewater manage ment purposes. Each of the ponds contained surface water at the time of the survey and do not contain any connection to the Salinas River or other aquatic features. Under the current regulatory

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 11 definition of Waters of the United States and implementation guidance, the USACE does not assert Clean Water Act Section 404 jurisdiction over active wastewater treatment facilities, or features that lack a significant nexus with traditional navigable waters. In addition, the State Wetland Definition and Procedures for Discharge of Dredged or Fill Material of Wa ters of the State (SWRCB 2019) states that industrial or municipal wastewater treatment or disposal features are not considered jurisdictional waters of the State. Isolated wastewater treatment ponds are also not considered “streams, lakes, or rivers” subject to regulation under Section 1602 of the California Fish and Game Code. As such, the active wastewater treatment ponds within th e IWTF project site are not
considered to be jurisdictional aquatic resources under the aforementioned regulations.

Regional Habitat Conservation Plans and Local Policies
The City of Salinas and Monterey County currently do not have an adopted regional Natural Community Conservation Plan or Habitat Conservation Plan. The 2002 General Plan for the City of Salinas and the 2010 General Plan for Monterey County outline local relevant policies related to biological resources. Below is the list of applicable policies from these plans:
 City of Salina
s General Plan:
o Policy Conservation/Open Space (COS)‐5.1: Protect and enhance creek corridors, river corridors, the reclamation ditch, sloughs, wetlands, hillsides and other potentially significant biological resources for their value in providing visual amenity, flood protection, habitat for wildlife and recreational opportun ities.
 County of Monterey General Plan:
o Policy Open Space (OS)‐5.23: The County shall prepare, adopt and implement a program that allows projects to mitigate the loss of oak woodlands, while also taking into consideration wildfire prevention/ protection. Consistent with California Public Resources Code Section 21083.4, the program shall identify a combination of the following mitiga
tion alternatives:
a) ratios for replacement,
b) payment of fees to mitigate the loss or direct replacement for the loss of oak woodlands and monitoring for compliance; and c) conservation easements.

The program shall identify criteria for suitable donor sites. Mitigation for the loss of oak woodlands may be either on‐site or off‐site. The program shall allow payment of fees to either a local fund established by the County or a state fund.

Until such time as the County program is implemented consistent with Public Resources Code Section 21083.4(b), projects shall pay a fee to the sta te Oak Woodlands Conservation Fund (OWCF). Replacement of oak woodlands shall

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 12 provide for equivalent acreage and ecological value at a minimum of 1:1 ratio.

The program shall prioritize the conservation of oak woodlands that are within known wildlife corridors as a high priority. The oak woodlands mitigation program shall be adopted within 5 years of adoption of the General Plan.

Because there is no tree removal as part of the project, the proje ct would also not be subject to the 2010 Monterey County Zoning Ordinance for tree removals and therefore, the project would not conflict with any local policies or ordinances protecting biological resources.

IMPACT FINDINGS
Special‐Status Natural Communities
One natural community under the jurisdiction of CDFW, riparian woodland, was mapped along the southwestern border of the IWTF BSA; however, this natural community is outside of the limits of the project site and, therefore would not be directly impacted by proposed project activities.

However, the riparian woodland could be indirectly impacted duri ng project activities, including from an increase or change in off‐site runoff, erosion, noise/vibration, and spread of invasive species. To avoid or minimize such indirect impacts, Mitigation Measures 1 and 2 would be implemented to ensure proper erosion control and storage of construction equipment and avoid the spread of invasive plant species.

Special‐Status Species
No special‐status plant species are expected to occur within either project site or to be adversely affected by the proposed project. Therefore, no mitigation is required for special‐status plants.

While special‐status bird and bat species have potential to forage in the vicinity of the IWTF project site, these highly mobile species would be expected to avoid the site during construction activities.

As such, construction activities within the IWTF project site are not anticipated to result in direct impacts to any special‐status animal species. However, construction activities at the IWTF could involve temporary increases in noise, dust, and vibration, which could indirectly impa ct common and special‐status bird species that have potential to nest within the riparian habitat along the Salinas River. Cliff swallows are also known to nest on the pump station within the IWTF, and the IWTF project site contains suitable nesting habitat for a variety of ground‐ nesting birds and birds that could nest in the ruderal vegetation on the margins of the site or within the irrigation canal.

Nesting birds are protected under the California Fish and Game Code and federal Migratory Bird Treaty Act. Construction activities that occur during the nesting bird season (typically January 1 through August 31) have potential to resu
lt in the direct or indirect take of nesting birds, which would be considered a significant impact. With successful implementation of the recommended impact avoidance Measure BIO‐3 (defined below), impacts to nesting birds (including special‐status bird species) would be avoided. No mitigation is re quired.

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 13 The Airport Lift Station project site is completely developed and does not contain suitable habitat for any special‐status animal species.

Critical Habitat
There is no designated or proposed critical habitat for any federally listed species within the BSAs.

The project would not result in any impacts to critical habitat, and no mitigation is required. No oak trees are located within the direct project disturbance limits; therefore, no mitigation is required.

Wetlands and Other Aquatic Resources
The IWTF project site contains an irrigation canal and the IWTF BSA includes a portion of the Salinas River. Based on the current design plans provided to LSA in July 2022, proposed improvements to the IWTF project site are located entirely outside of any jurisdictional areas associated with the Salinas River (including riparian habita t), and no new encroachment/fill is expected to occur in resources associated with the Salinas River.

Additionally, planned improvements such as the new pipelines between percolation ponds included under the Pond Automation/Distribution and Pond 3 Pump Station Package would be placed along the existing roads/berms and would avoid direct impacts to the irri gation canal. If any component of the final site plan would result in any direct modifications (such as grading, the placement of any fill material or structures, etc.) within the banks of the irrigation canal, a formal delineation of the aquatic resources within the proposed development footprint should be conducted, and th e CDFW, USACE, and RWQCB should be consulted to verify jurisdictional status and any potential permitting and/or mitigation requirements.

Construction of the proposed pipeline could result in indirect temporary impacts such as dust, potential fuel spills from construction equipment, construction‐related runoff, and erosion, which could potentially enter the irrigation canal or th e Salinas River. Construction activities involving ground disturbance could also result in the introduction and/or proliferation of nonnative, invasive plant species, which could outcompete and/or displace native vegetation within the irrigation canal or adjacent riparian habitat areas. To avoid or minimize such indirect impacts, the project will require proper erosion co
ntrol and storage of construction equipment, as recommended in Mitigation Measure BIO‐1 (defined below). Furthermore, to avoid the spread of invasive plant species, Mitigation Measure BIO‐2 is recommended. With successful implementation of recommended Measures BIO‐1 and BIO‐2, potential indirect impacts to jurisdictional features would be less than significan
t under CEQA.

Wildlife Movement
The wildlife species that occur in the project vicinity are adapted to the urban‐wildland interface and ongoing IWTF operations, and the project would not introduce new effects to the areas. The noise, vibration, light, dust, or human disturbance within construction areas would only temporarily deter wildlife from using areas in the immediat e vicinity of construction activities. These indirect effects

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 14 could temporarily alter migration behaviors, territories, or foraging habitats in select areas.

However, because these are temporary effects, it is likely that wildlife already living and moving in close proximity to the IWTF, and proposed Airport Lift Station project sites, would alter their normal functions for the duration of the project construc tion and then re‐establish these functions once all temporary construction effects have been removed. The project would not place any permanent barriers within any known wildlife movement corridors or interfere with habitat connectivity. The impact is considered less than significant, and no additional mitigation is required.

RECOMMENDED IMPACT AVOIDANCE, MINIMIZATION, AND MITIGATION MEASURES The following measures are recommended to be implemented to avoid, minimize, and/or mitigate impacts on nesting birds and jurisdictional aquatic resources.

MM BIO‐1 Erosion Control and Best Management Practices (BMPs). Prior to the start of construction, the Project Contractor shall clearly delineate all construction areas and equipment staging areas. The designated areas shall be located in such a manner as to prevent any loose soil or spill runoff from entering the irrigation canal, the Salinas River, or adjacent riparian vegetation communities. All equipment maintenance, staging, and dispensing of fuel, oil, or any other such activities used by the Project Contractor shall occur in these designa ted staging areas.

Adequate erosion and sedimentation barriers (e.g., silt fencing) shall be installed around the perimeters of work areas by the Project Contractor and remain in place during project construction to prevent any sediment or debris from entering the adjacent irrigation canal or Salinas River. For work areas adjacent to the Salinas River or irrigation ca
nal, barriers shall consist of a minimum 3‐foot‐tall silt fencing buried to a depth of approximately 3–6 inches below the soil surface (or as otherwise specified in a project‐specific erosion control or spill prevention plan).

These barriers shall be inspected by th e Project Contractor on a regular basis and maintained and repaired as necessary to ensure that there are no holes or tears that could entrap and pose a hazard to wildlife.

MM BIO‐2 Invasive Species Control. Any nonnative plants removed during the course of construction shall be contained and properly disposed of off site. All mulch, topsoil, seed mixes, or other plantings used for erosion‐control shall be free of invasive plant species seeds or propagules. No plant species listed on the California Invasive Plant Council (Cal‐IPC) inventory shall be installed in the project site, and all plant palettes proposed to be installed
on the project site(s) shall be reviewed and
approved by a qualified biologist.

MM BIO‐3 Nesting Bird Surveys and Active Nest Avoidance. Ground disturbance and vegetation removal shall take place outside of the active nesting bird season (i.e., January 1–August 31), when feasible, to avoid impacts to nestin g birds. Should project activities (such as vegetation removal, initial ground disturbance, or operation of heavy equipment) be initiated during the nesting bird season, a qualified biologist shall conduct a nesting bird survey no more than 30 days prior to any ground disturbance or vegetation removal to ensure tha t birds are not engaged

9/21/22 «P:\CPZ2201 Salinas Wastewater Treatment\PRODUCTS\Bio\Biological Tech Assessment_Salinas Wastewater Treatment_Draft 9‐21‐22.docx» 15 in active nesting within or immediately adjacent to the IWTF project site. If nesting birds are discovered during preconstruction surveys, the biologist shall identify and delineate an appropriate buffer (depending on the circumstances and specific bird species) where no clearing, grading, or construction activities with potential to have direct or indirect impacts on th e nesting birds are allowed to take place until after the birds have fledged from the nest, or the qualified biologist has determined that the nest is no longer active. If a nesting bird survey is required, written results of the survey by the biologist shall be submitted to the City prior to the sta rt of ground disturbing activities.

CONCLUSION
Based on field observations coupled with the habitat suitability analysis conducted for this assessment, the proposed improvements to the IWTF and Airport Lift Station project sites have low potential to impact regionally occurring special‐status wildlife species. The project improvements at both locations are not anticipated to directly impact any special‐status plan t species, special‐status natural communities, the irrigation canal, the Salinas River, or other habitats of concern.

The implementation of the recommended Measures BIO‐1 through BIO‐3 would avoid potentially significant direct impacts on nesting birds and avoid or minimize indirect impacts on the irrigation canal, the Salinas River, and riparian commu nities to a less than significant level.
