Introduction
City of Salinas
November 2022
City of Salinas Industrial Sewer Collection System Overview The City of Salinas is incorporated as a charter City on March 4, 1874 and operates under the Council-Manager form of government. The City is governed by a six-member Council elected by districts for four-year alternating terms and a Mayor elected at large for a two-year term. The Council appoints the City Attorney and the City Manager who is responsible for day-to-day administration of the City under the policy direction of the Council.
The City strives to protect the environment to the greatest degree possible and ensure the collection system is protected and utilized properly. The responsibility includes preventing overflows, which may include restricting or prohibiting the volume, type, or concentration of wastes added to the system.
The City of Salinas operates a unique Industrial Wastewater Sewer Collection, Conveyance & Treatment System. While most municipalities maintain a Storm Sewer and a Sanitary Sewer System only, Salinas maintains a third collection system for a service area on the southern end of the City. The Industrial Wastewater Sewer receives industrial wastewater discharges from 24 industrial users via permitted connections; and conveys the discharge to a 200-acre treatment facility located along the Salinas River. The treatment facility and collection system are solely funded by user fees from the current roster of 24 industrial users. The industrial waste fund is adequate for the immediate operations and maintenance of the treatment facility and collection system.
The City industrial wastewater collection system consists of approximately 0.5 miles of force mains, 6 miles of gravity sewer lines, 90 manholes, and 1 lift station.
City Council meetings are held twice monthly on Tuesdays at 4:00 pm at City Hall located at 200 Lincoln Avenue, Salinas CA, 93901.
The City Council authority and responsibility includes the adoption and approval of the SSMP and any formal updates to the SSMP. The Board Meeting Minutes for the adoption of the 2022 SSMP, Rev.1 should be included with the SSMP on the City’s website after recertification.

EXECUTIVE SUMMARY
The State Water Resources Control Board’s (SWRCB’s) Statewide General Waste Discharge Requirements (WDR) for Sanitary Sewer Systems, Order No. 2006-0003-DWQ, Amended Monitoring and Reporting Program (MRP), Order No. WQ 2008-0002-EXEC, and Order No. WQ 2013-0058-EXEC require the City of Salinas (City) to have and maintain a Sewer System Management Plan (SSMP), which provides “a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system” in order to “help reduce and prevent sanitary sewer overflows (SSOs), as well as mitigate any SSOs that do occur” [Order No. 2006- 0003-DWQ Section D.13 (i)].
The SSMP includes the following eleven (11) Elements:
Goal
City Industrial System goals, which are included in the SSMP, are:
▪ Properly manage, operate, and maintain the wastewater collection system; ▪ Maintain design construction standards and specifications for the installation of new wastewater systems;
▪ Verify the wastewater collection system has adequate capacity to convey industrial wastewater during peak flows;
▪ Minimize the frequency of system overflows;
▪ Respond to system overflows quickly and mitigate the impact of the overflow; ▪ Provide training on a regular basis for staff in collection maintenance and operations;
▪ Develop a closed-circuit televising (CCTV) program for the industrial sewer collection system;
▪ Identify and prioritize structural deficiencies and implement short-term and long-term maintenance and rehabilitation actions to address each deficiency;
▪ Meet all applicable regulatory notification and reporting requirements; and ▪ Provide excellent customer service.
Organization
The Organization Element of the SSMP identifies City and Contract Staff, who are responsible for implementing the SSMP, responding to SSOs, and meeting the SSO reporting requirements, and identifies the lines of authority of SSO responsibilities and chains of communication for SSO response and reporting. The Legally Responsible Officials (LRO) are also designated in this SSMP Element in order to meet the SWRCB requirements for completing and certifying SSO reports in the SWRCB’s online regulatory information database and tracking system, California Integrated Water Quality System (CIWQS).
Sewer System Management Plan – Revision 01
Introduction
City of Salinas
November 2022
Legal Authority
This SSMP Element outlines the City Municipal Code Chapters & Ordinances that provide the City with the legal authority to:
a. Prevent illicit discharges;
b. Require that sewers and connections be properly design and constructed; c. Limit the discharge of fats, oils, and grease (FOG) and other debris that may cause blockages; and
d. Enforce any violation of its sewer ordinances.
Operation and Maintenance Program
City operation and maintenance of its collection system ensures that the system is kept in good working condition, and this SSMP Element outlines the work that is conducted to accomplish the optimal operation and maintenance of the City industrial collection system. This SSMP Element details a:
a. Sanitary sewer and storm drain system maps;
b. Preventative Maintenance Program, which consists of activities such as cleaning of sewer lines and other regular inspections and maintenance; c. Rehabilitation and Replacement Plan, which focuses on sewer pipes at risk of collapse or prone to more frequent blockages due to pipe defects and includes a time schedule for funding and completing the capital improvement plan; d. A plan and schedule to develop a training program and procedures for City Staff and Contractor collection system operation and maintenance activities; and e. Equipment and replacement part inventory with critical replacement parts and equipment identified.
Design and Performance Provisions
The Design and Performance Provisions Element describes the standards and specifications for new construction, repair of the existing sanitary sewer system, and the inspection and testing of these items.
Overflow Emergency Response Plan
The Overflow Emergency Response Plan (OERP) contains the following information in order to protect public health and the environment in the event of a SSO:
a. Notification directives for primary responders and regulatory agencies; b. Notification directives for regulatory agencies and other potentially affected entities for SSOs that potentially affect public health or reach the waters of the State;
Sewer System Management Plan – Revision 01
Introduction
City of Salinas
November 2022
c. A plan and schedule to develop emergency operations procedures for response activities, such as sewer spill volume estimation, sewer spill mitigation, traffic and crowd control; and
d. A plan and schedule to develop a SSO mitigation and impact assessment program.
FOG Control Program
The goal of the FOG Control Program is to reduce the amount of FOG discharged to the sanitary sewer system. The City has determined that FOG is not a problem within the Industrial Sewer Collection and Conveyance System and therefore is not required to meet additional regulatory requirements identified for this Element.
System Evaluation and Capacity Assurance Plan
The City has conducted several studies of the Industrial System between 2001 and 2008 to assess the existing, near term and long-term capacity needs to safely convey wastewater to the Industrial Wastewater Treatment Plant. These analyses indicate that there is adequate capacity under existing conditions for the collection and conveyance system. In the near term, when discharges reach 2 mgd (estimated in 2025), some improvements may be required , however additional analyses will be required to confirm capacity needs. Capacity needs for the long term will depend on the number and size of facilities connected in the future. The City has identified one area for capacity upgrades within the Industrial System. The Airport Boulevard Lift Station is currently undergoing an analysis to upgrade capacity to accommodate existing and future flow additions upstream.
Monitoring, Measurement, and Program Modifications
The City monitors the implementation of the SSMP Elements in order to measure the effectiveness of the City SSMP program in reducing SSOs. This SSMP Element outlines the manner in which each SSMP Element is monitored and evaluated and the schedule with which the City completes this monitoring and evaluation.
Sewer System Management Plan Program Audits
The SSMP Program Audits Element outlines the audit process and identifies City Staff responsible for conducting or participating in SSMP Program Audits and generating the required SSMP Program Audit Report. SSMP Program Audits must occur at a minimum of every two (2) years and are required to evaluate the City SSMP Program, identify program deficiencies, and provide an improvement schedule based on the audit findings.
Communication Program
This SSMP Element describes the manner in which the City communicates the development, implementation, and performance of its SSMP with the public in order to provide them with the opportunity to provide input as the SSMP program is developed and implemented.

2.4 Chain of Communication for Responding to SSOs [WDR D.13(ii)(b)] SSO reports typically begin with a call from an observer to the City Office or 911 dispatchers.
City of Salinas
Business Hours: (831) 758-7233 7am - 3:30pm Monday through Friday, except Legal Holidays
After Hours: 911
During the process of responding to a SSO, the following actions are taken as outlined in Figure 3-1 and described below to verify the report and ensure the safety of the public:
1. During business hours, Wastewater Operators receive the call from an observer, the Police Department or the Fire Department and obtains the location of concern and a description of the problem. The name and phone number of the caller is requested and documented if not anonymous for follow-up information.
2. After hours, the On-Call Staff proceeds to the location to verify the report.
3. If a SSO is verified, the On-Call Staff notifies the CPO and directed to the described location. The Overflow Emergency Response Plan (OERP) is initiated.
4. Operations staff will notify the CPO and Wastewater Manager both during and after business hours.
5. California Office of Emergency Services (CalOES) must be contacted within two (2) hours of a Category 1 SSO, when the SSO is over 1,000 gallons or the SSO reaches a drainage channel or surface water.

4.3.1. CCTV Inspection
The City is planning to conduct contracted CCTV investigations of the entire system between in 2023. This information will be one of the primary methods to identify sewer line rehabilitation and replacement projects in the future. Prior CCTV investigations conducted in 2013 are currently being reviewed to identify areas requiring maintenance and rehabilitation and replacement.
When 2023 CCTV investigations are complete they will be analyzed to; identify, rank and prioritize areas of the sewer system that require rehabilitation and replacement. A summary of these CCTV investigations will be included in Appendix 4E when completed.
4.3.2 Line Cleaning
The City plans to clean the entire system to facilitate a CCTV project which will televise the entire City sewer system in 2023.
The City will be evaluating the frequency at which the entire system is cleaned based on the results of future sewer line cleaning and the results of CCTV data completed in conjunction with this contracted cleaning. The City will complete an analysis of this data and based on the results, develop a new schedule for system wide sewer cleaning which will be included in future revisions to the SSMP. An analysis of sewer line cleaning and CCTV data will be included in Appendix 4A when complete. Areas where SSOs have occurred in the past will monitored and cleaned as warranted based on observed flow conditions until the line cleaning and CCTV assessment is complete and a formal schedule can be determined.
4.3.3 Manhole Inspection
City Manholes will be inspected in conjunction with sewer line cleaning activities. The City utilizes the Manhole Inspection Form for routine documentation of manhole conditions. When significant issues are observed during these routine manhole inspections, a more detailed inspection and assessment is conducted by maintenance staff. Relevant information from these sheets is planned to be maintained for consideration in future rehabilitation and/or CIP. An example of the City Detailed Manhole Inspection Form is located in Appendix 4B.
4.3.4 High Maintenance Areas
The City will identify High Maintenance Areas (HMAs) through CCTV and Line Cleaning observations. HMAs will be added to the City’s HMA list as they are identified. A list of HMAs will be included in Appendix 4C when completed. A cleaning interval for HMAs will be assigned as areas are identified within the Industrial System.
4.3.5 Lift Station Operation and Maintenance

ELEMENT 7 – FATS, OILS, AND GREASE (FOG) CONTROL PROGRAM The City of Salinas does not have a significant number of Commercial Facilities that contribute Fats, Oils and Grease into the industrial sewer system. FOG has not been a contributing factor in any industrial system SSOs.
7.1 Regulatory Requirements
WDR Order No. 2006-0003-DWQ Section D.13(vii) states:
Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification as to why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:
(a). An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG;
(b). A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;
(c). The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;
(d). Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e). Authority to inspect grease producing facilities, enforcement authorities, and whether the Agency has sufficient staff to inspect and enforce the FOG ordinance; (f). An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and (g). Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.

November 2022
7.2 City Determination that a FOG Program is not Required [WDR D.13(vii)(a-g)]
The Cities industrial waste collection system has neither historically nor currently had Fats, oils or grease issues within its collection system. Most of the Industrial Waste Facility (IWF) users are fresh vegetable processors, packers, and coolers. Included in this group are the fresh-pack salad producers that continue to be the fastest growing segment of the City's users. Chlorinated effluent, ammonia refrigerant, solids, and hydraulic oil spills typify the potential concerns with their wastewater discharge. Two box companies comprise the next group of users. These companies manufacture corrugated cardboard containers using prefabricated rolled paper and use ink and waxes in the process of labeling and finishing the boxes. Control of heavy metals, hydraulic oil spills, wax and starch spills, high TDS, varying pH and slug discharges are potential concerns from this group.
Monterey Fish Company is the sole processor of seafood at one facility. Squid, herring, crab and shrimp are among the products prepared at this facility. From this seafood group, the City specifically monitors BOD, screening and sanitation. Although oils from fish processing present a potential concern, the oils, if any, do not present an issue for buildup in the collection system.
Due to the small percentage of flow from this facility this user does not present a fats oils or grease source control problem for the collection system. There are no fats or grease discharged from the facility.
A FOG program is not indicated with the current industrial waste dischargers group.

8.1 Regulatory Requirements
WDR Order No. 2006-0003-DWQ Section D.13(viii) states:
The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
(a). Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape the system) associated with conditions similar to those causing overflow events, estimates of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events;
(b). Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and (c). Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP may include an implementation schedule and may identify sources of funding. (d). Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule may be reviewed and updated consistent with the SSMP requirements as described in [WDR Order 2006- 0003-DWQ] Section D.14.
8.2 System Evaluation [WDR D.13(viii)(a)]
Overview and Background
The City of Salinas IWTF is located south of the City adjacent to the Salinas River. It treats industrial wastewater discharges from industrial customers located in the southeastern part of the City. The industrial wastewater is conveyed from customer sites to the industrial treatment facility by the City’s industrial sewer system. This chapter addresses the industrial sewer system.
The industrial sewer system is completely separate from the sanitary (domestic) sewer system.
All sanitary (domestic) wastewater is collected in a separate sanitary sewer system and conveyed to the M1W RTP located north of Marina. A separate Sanitary Sewer Management Plan addresses the sanitary sewer system.
The City has conducted several studies over the past years to evaluate capacity needs in the industrial sewer system. These studies include:

Existing Industrial Sewer System
The major industrial sewer conveyance system consists of approximately 24,000 feet of 20-, 27, 33, 36 and 42 -inch reinforced concrete and HDPE pipe. The pipeline system conveys industrial flows from the customer locations to the industrial wastewater plant.
The 27-inch pipe originates where Sanborn Road crosses over the railroad tracks, passes through a 60-foot-long inverted siphon at the Abbott Street and East Blanco Road intersection, and then continues downstream for about 1600 feet where it intersects the east 27-inch trunk line. From there, it continues for an additional 2600 feet before it enters the 36-inch pipeline near the intersection of East Blanco Road and La Mesa Way.
The 36-inch pipeline then drains to and through the former Salinas wastewater treatment plant site (TP1 site). At that point, it discharges into a new 42 -inch HDPE pipeline that flows southerly to the IWTF.
Industrial Wastewater Flow Projections
The industrial customers are primarily food processing and related businesses. Many customers conduct fresh vegetable packing operations. Some customers provide related services such as manufactured ice, refrigerated warehousing, and corrugated and solid fiber boxes.
The industrial wastewater facility operates year-round. However, different from a sanitary sewer system, the industrial sewer flows are lower in the winter because some customers, particularly fresh vegetable packing and cooling facilities, move their operations to warmer southern locations. Approximately ½ of the industries remain open year- round.
The industrial system must be able to accommodate the flows during the high use periods, which occur during the summer peak growing/harvesting season. The treatment facility must be able to treat the average monthly flow during the high use periods and have peaking ability to accommodate the high day flows. The conveyance system from customers to the treatment facility must accommodate the high day (peak) flow.
Sewer System Management Plan – Revision 01
Element 8 – System Evaluation and Capacity Assurance Plan
City of Salinas
November 2022
Table 1 summarizes the total projected flows for the existing, immediate, near-term (2021-2025), and ultimate timeframes. The City expects new customer locations will be added to the system in the future and is planning accordingly. Additional future flows will actually be phased in according to actual development schedules.
The average daily and peak daily flows are important for treatment facility design. The estimated instantaneous peak flows are short duration, e.g., 15–minute to hourly peaks, that are used in evaluating pipeline conveyance needs.

(1) Average daily and peak daily flows are important for treatment facility design. (2) Estimated instantaneous peak flows are short duration, e.g., 15-minute or hourly, peaks that may also impact conveyance system design.
Capacity Evaluation
Table 2 shows the maximum capacities of the major existing conveyance pipelines, according to the previous hydraulic analysis of the major industrial wastewater pipeline system. The three segments with the lowest capacity, about 5.6 - 5.9 mgd, are due to flat slope relative to the pipe diameter.
The instantaneous peak flow projections shown in Table 1 were compared with the design capacity of the existing system to determine requirements for additional facility capacity. Then, as discussed below under “Capacity Enhancement Measures”, recommendations were developed for future improvements to accommodate the projected flows.
Based on the hydraulic evaluation, the existing major conveyance system is adequate to meet estimated peak flows for immediate needs. Some additional capacity will be required for near-term and ultimate needs.
The reinforced concrete pipe (RCP) from its upstream end at Sanborn Road to the TP1 site is in good condition for its age. With one segment having been replaced with 36-inch HDPE along Blanco Road. While the 42-inch pipe that conveys flow from the TP1 site to the industrial treatment facility is new and replaced a badly deteriorated 33-inch line.

8.3 Design Criteria
Chapter 36 “Industrial Waste, Wastewater Collection and Discharge” of the City’s Municipal Code specifies the requirements for discharge to the City’s industrial wastewater system. These requirements are applicable to existing and new customers of the industrial wastewater system.
As discussed above regarding the system evaluation, the existing IWWCS was evaluated for its adequacy to convey existing and future peak flows to the IWTF. The estimated instantaneous peak flows are short duration, e.g., 15–minute to hourly peaks, are used in evaluating and designing pipeline conveyance needs.
Unlike the sanitary sewer system, the peak flows for the industrial wastewater system occur during the summer peak growing season months. Winter rainfall (RDII) is not an issue for capacity of the IWWCS, as industrial wastewater flows are very low in the winter months. During the period with high industrial wastewater discharges, there is no or negligible rainfall.
The hydraulic criteria evaluated the pipes adequacy to handle the projected flows without surcharge, i.e., flowing full but no surcharge based on Manning’s equation. Those pipes without adequate capacity to meet the criteria have been identified for improvement.
The City’s Standard Specifications (current version) specify the requirements for sewer pipe materials, installation methods, and testing for new sewer improvements.
Capacity Enhancement Measures
The July 2008 Summary Report “Conceptual Approach for Industrial Wastewater System Expansion” lays out a plan of action for future steps to be undertaken by the City to assure adequate capacity in the industrial wastewater system for existing and future users. The Summary Report addresses the following three major issues at a conceptual planning or “feasibility” level:
o Conceptual plan for industrial waste system facilities – feasible overall approach to meet future capacity needs.
o Conceptual phasing for plan implementation, and conceptual “order-of-magnitude” cost estimates.
o Conceptual identification of potential alternative funding methods.
The Summary Report identifies near-term and ultimate needs while providing a feasible framework for meeting those needs. It is not intended to provide detailed information on specific designs to provide additional capacity. The City will conduct subsequent detailed evaluations to adequately select, design and implement the improvements, including environmental review.
Below is a summary of the recommended capacity enhancement measures. These measures are prioritized for implementation by the timeframe needed.
Sewer System Management Plan – Revision 01
Element 8 – System Evaluation and Capacity Assurance Plan
City of Salinas
November 2022
Immediate Needs to 2020
The City’s industrial wastewater system will require some improvements in order to meet estimated needs. The Industrial Lift Station located at the south end of Airport Boulevard near Hansen Street will require increased capacity to accommodate any additional flows upstream. However, the major industrial pipeline system has adequate capacity for estimated peak flows. Some system redundancy is provided by the Industrial Wastewater Diversion Project which consists of a shunt/bypass to the M1W sanitary sewer system installed at the TP1 site. M1W’s Salinas Area Pump Station (SAPS) is located at the TP1 site which conveys sanitary wastewater from the City to the RTP operated by M1W. The Industrial Wastewater Diversion Project was completed in 2016. This project also included construction of an emergency wastewater bypass system to allow mixed wastewaters to flow to the IWTF instead of to the Salinas River in the event of a catastrophic failure at the M1W Salinas Pump Station.
Near-Term Needs
The near-term timeframe is anticipated to occur sometime from 2021 to 2025, or longer, whenever discharge during high use months increase by 2 mgd on an average daily basis. Recommended near- term improvements were implemented to provide additional capacity for future flows from new customers. However additional studies may be necessary to determine if other improvements are required.
In the near-term timeframe, the majority of additional future flows from future customers are expected to enter the existing major conveyance system at the 36-inch tributary pipeline located at East Blanco Road and Blanco Circle. Upstream of this 36-inch tributary pipeline, the existing minimum capacity is 7 mgd with the exception of a short 70-foot hydraulic bottleneck at Sanborn Road and the railroad with a capacity of 5.9 mgd. It is anticipated that the existing capacity in the upstream portion will be adequate to handle future needs. If needed, the short hydraulic bottleneck could be improved.
The identification of required improvements assumes that some wastewater flows will be diverted to the RTP from the TP1 site.
In addition, there may be improvements needed to the industrial wastewater laterals that connect from the industry sites to the major conveyance pipeline. It is assumed that these improvements would be done by the individual developers as part of the development plans and may consist of both on-site and some off-site improvements depending on the specific connection locations.
Ultimate Needs
The improvements identified above for near-term implementation are sized to accommodate the anticipated buildout total instantaneous peak flows of 12 to 15 mgd reaching the TP1 site and treatment facility.
Ultimately, the need for additional pipeline improvements would depend on future additions of industrial customers, and the City’s decisions in the near-term on the appropriate location for additional treatment capacity. This plan will be updated as needed consistent with future updates to the conceptual expansion plan.

8.4 Schedule and Funding for Capacity Improvements
Table 3 summarizes the timeframe and estimated capital costs for the conceptual improvements to provide additional capacity in the industrial wastewater system. These order of magnitude costs by timeframe are at a conceptual planning level and are based on previous studies. The costs will be updated and refined as part of subsequent detailed studies to refine and select specific improvement projects.

Element 8 – System Evaluation and Capacity District Assurance Plan
City of Salinas
November 2022
The City currently funds the industrial wastewater system through a monthly user rate consisting of: a monthly service charge, total flow charge, and an average BOD charge. The rates cover operations and maintenance expenses, capital improvements and past debt service on any outstanding bonds that have been issued for capital improvements.
Capital improvements to provide capacity for future customers also benefit existing customers by improving the overall function of the IWWCS. the existing treatment facility.
Potential funding methods to cover the costs of these capital improvements are identified below. The potential funding methods must be further evaluated to determine their applicability. While all the options are feasible, some may be more applicable or more desirable for the specific conditions. It is anticipated that a combination of options will be utilized.
As recommended in the conceptual expansion plan, the City is planning to conduct a detailed financing study to determine the preferred approach and appropriate methods for funding the required improvements for both pipeline conveyance (addressed in this chapter) and for treatment facility expansion. It is anticipated a combination of multiple funding sources will be used. Most of the methods are available only to municipalities or other government agencies; however, there are some that could be utilized by the individual industries.
Grant programs from the EDA Public Works and Economic Development Program, the State Water Resources Control Board and others are preferred funding sources for IWWCS upgrades. If grant funding proves to be unavailable other potential funding options may also include:
o User rates
o Connection fees
o Municipal bonds
o Special assessment districts
o Public/private partnerships
o California Infrastructure and Economic Development Bank:
infrastructure state revolving fund program; industrial development bonds
o California State loans and grants: State Revolving Fund (SRF); direct state appropriations
o Federal grants and loans: EDA Public Works and Economic Development Program; direct federal appropriations
The schedule for implementation of future capacity improvements will depend on the available funding and the schedule for future additions and expansion of the IWWCS. As part of its annual budgeting and CIP process, City staff will refine the implementation schedule for specific projects.
As the City refines and implements the “Conceptual Approach for Industrial Wastewater System Expansion”, this plan will be updated accordingly.

Sewer System Management Plan – Revision 01
Element 10 – Sewer System Management Plan Program Audits
City of Salinas
November 2022
SSMP Audits must be conducted continuously on a *two-year interval. *It should be noted that the SWRCB is in the process of updating the WDRs for Sanitary Sewer Systems. It is anticipated that these new regulations will be adopted by the SWRCB in December 2022. Based on a review of these DRAFT WDRs a different schedule for SSMP Updates (6- Years) and SSMP Audits (3-Years) is anticipated. The City must track the adoption of these new WDRs and adjust SSMP Audit and Update schedules according to final adopted WDRs when issued.
To assist in the audit process, the City should consider annual reviews and line revisions (draw a line through what is changed, handwrite in the change, date and initials of person making changes) for minor revisions (ex: staffing) to specific SSMP Elements and associated supporting documents.
These reviews and revisions will ensure current operational practices and procedures are reflected in the SSMP and documentation of these activities is readily available during an audit by the Regional Water Quality Control Board or State Water Resources Control Board.
SSMP Audit Reports must be kept on file with the SSMP and available to regulators and the public upon request. In accordance with the 2013 MRP records are to be kept a minimum of five (5) years. In accordance with that requirement the 2022 City SSMP Audit Report is included in Appendix 10A.
