A. The Work contemplated herein constitutes a public work within the meaning of Labor Code sections 1720 and 1771. It shall be mandatory upon the Consultant and upon any Subcontractor, to pay not less than the said specified prevailing rates of wages to all workers employed by them under the Contract in accordance with Labor Code section 1774. The Director of the Department of Industrial Relations ("DIR") of the State of California has determined the general prevailing rate of wages of per diem wages in the locality in which the work is to be performed for each craft or type of worker needed to execute the Contract. The Consultant acknowledges that it has examined the prevailing rate of per diem wages as established by the DIR. Copies of the current schedules for prevailing wages are on file at City Hall, and the contents of those schedules are incorporated herein as if set forth in full. The Consultant shall post a copy of the applicable prevailing wage determinations at each job site, along with any other work place posters required by law.

B. The City will not recognize any claims for additional compensation because of the payment of prevailing wages. The possibility of wage increases is one of the elements to be considered by the Consultant in determining its proposal, and will not under any circumstances be considered as the basis of a claim against the City.

C. By executing this Contract Consultant warrants that it has registered with the Department of Industrial Relations in accordance with Labor Code section 1725.5.

2. PREVAILING WAGE RECORDS
A. The Consultant and each subcontractor shall keep an accurate payroll record which shows the name, address, social security number, correct work classification (in accordance with the wage decision), both straight and overtime worked each day and week, and hourly rate of pay, gross wages earned, deductions made and net wages paid to each journeyman, apprentice, worker or other employee paid by the Consultant /subcontractor in connection with the Work. These payroll records shall be certified and shall be made available at Consultant's principal office. These records shall be maintained during the course of the Work. The Consultant and all subcontractors shall make the certified payroll records available for inspection by City representatives upon request and shall permit such representatives to interview employees during the work hours on the job site.

B. The City shall notify the Consultant in writing of any discrepancies or violations that are discovered during such inspections. Written notification pursuant to this Section shall include the actions that will be necessary to resolve the discrepancies and/or violations.

often than monthly), with a statement of compliance signed under penalty of perjury. Such certified payroll reports shall be transmitted electronically to the DIR.

D. The City will not recognize any claims for additional compensation because of the payment of the prevailing wages. The possibility of wage increases is one of the elements to be considered by the Consultant in entering into the Contract, and will not under any circumstances, other than delays caused by the City, or the City’s agents, be considered as the basis of a claim against the City.

3. Labor Discrimination
Attention is directed to Section 1735 of the Labor Code, which reads as follows:
“No discrimination shall be made in the employment of persons upon public works because of their race, color, national origin or ancestry, physical handicap, mental condition, marital status, or sex of such person, except as provided in Section 12940 of the Government Code, and every General Contractor for public works violating this section is subject to all the penalties imposed for a violation of this chapter.” 4 Eight-Hour Day Limitation

CITY COUNCIL AGENDA REPORT
MEETING DATE: July 16, 2025 ITEM # 10
SUMMARY:

CONSIDERATION OF RESOLUTION 25-76 APPROVING THE SEWER SYSTEM

MANAGEMENT PLAN (SSMP) UPDATE
INITIATED OR REQUESTED BY: REPORT COORDINATED OR PREPARED BY:
[ ] Council [X] Staff
[ ] Other
Amber Wallace, Senior Civil Engineer

OBJECTIVE
The objective of this report is to provide sufficient information to the City Council for it to adopt Resolution 25-76 approving the Sewer System Management Plan (SSMP) Update.

RECOMMENDED ACTION
Staff respectfully recommends that the City Council approve Resolution 25-76 approving the Sewer System Management Plan Update.

BACKGROUND
The City owns and operates a sanitary sewer system for the benefit of its citizens, businesses, and commercial and industrial customers. The system is regulated by the State Water Resources Control Board (State Water Board) because of threats that spills and overflows may occur. Since December 2006, the City has been enrolled in the Statewide Sanitary Sewer Systems General Order (General Order). The intent of the General Order is to provide a consistent, statewide regulatory approach to address sewage spills.

The first State Water Board adopted General Order, Order No. 2006-0003, was adopted on May 2, 2006. A “Reissued General Order” (Order No. 2022-0103-DWQ) was adopted on December 6, 2022, and became effective on June 5, 2023. The City is currently enrolled in the “Reissued General Order.” The “original” and “reissued” General Order have always required that the City develop, implement, and maintain a Sewer System Management Plan (SSMP) to proactively manage the system, reduce spill frequencies, and respond quickly to any spill that may occur. As the centerpiece for compliance with the General Order, the City has maintained the SSMP as required by the General Order. This is the third SSMP update. The original SSMP was adopted in 2008, revised in 2015, and revised again in 2018.

This SSMP update benefits from the City’s recent SSMP audit, (completed in January 2025 and due to the State Water Board on 2/2/2025) and the recent Sewer Master Plan Update (performed on April 1, 2025). This SSMP satisfies new requirements in the 2022 General Order. The City has updated the required elements in the SSMP. For example, the GIS effort to document (map) City assets is now included in the SSMP, including such items as valves, manholes, pipe diameters, and lift/pump stations. The recent effort to evaluate sewer capacity, assess sewer infiltration and inflow (I/I), and lift/pump station capacity (done in the Sewer Master Plan), provided timely information for this SSMP update.

Items found to be missing in the SSMP audit are now included in the update.

The General Order requires regular reporting, something that City performs regularly. The new General Order now requires reporting on “Category 4” spills. “Category 4” spills are spills below 50 gallons. This is now included in the SSMP, although the City has complied with the requirement for some time now. When such spills (or larger) occur, the City usually recovers all spilled material and disinfects the area according to this SSMP and the City Sanitary Sewer Overflow Response Plan. This SSMP and a GIS map of the sewer system will be uploaded into the State Water Boards reporting system, as required by the General Order.

ANALYSIS
The goal of the Sewer System Management Plan is to provide the City a guiding document to properly manage, operate, and maintain all parts of the sanitary sewer system. This updated SSMP will help reduce and prevent sewer spills and overflows as well as mitigate any spills that do occur within the City service area.

SSMP goals reflect performance, safety, levels of service, resource use, and other considerations that the City is committed to operating the sewer system. A good SSMP preventive maintenance program is one component in keeping a system in good repair and preventing excessive infiltration/inflow (I/I), service interruptions, and system failures. A good SSMP can help in protecting the capital investment in the collection system. 218 CONSIDERATION OF RESOLUTION 25-76 APPROVING THE SEWER SYSTEM MANAGEMENT PLAN (SSMP) July 16, 2025

Strategic Plan Integration
The SSMP supports “Core Services and Infrastructure” by ensuring the sewer collection system is wellmaintained. It also supports “Climate and Energy Resiliency” by protecting our environment.

Environmental Considerations
The current action is not a project that is subject to CEQA because it is not an activity that may cause either a direct or reasonably foreseeable indirect physical change in the environment. (Pub. Resources Code, § 21065; CEQA Guidelines §§ 15060(c), 15378(a).)
Commission Recommendation
Staff plan to share the SSMP with the Environmental and Utilities Commission at their next regularly scheduled meeting.

Strategic Plan Integration
The SSMP supports “Core Services and Infrastructure” by ensuring the sewer collection system is wellmaintained. It also supports “Climate and Energy Resiliency” by protecting our environment.

Alternatives
The City Council may choose among the following alternatives:
1) Approve the recommended actions as stated above.
2) Amend the recommended actions.
3) Decline to approve the recommended actions or cancel the project.

Staff recommend Alternative 1 to approve the SSMP Update to ensure the report is filed with the State of California by the August 2, 2025, deadline.

Coordination and Review
This report was prepared by the Capital Projects Department in coordination with and review by the Public Works Department.

Budget/Cost Impact
The $200,000 budget for the update is in the City’s current Capital Improvement Program (CIP) as CIP 30000:

Sewer System Management Plan Update and was taken from the Sewer Enterprise Fund 501-9410. The future budget impacts to the updated state sewer collection system requirements will be accounted for in the Sewer Rate Study process.

June 2025 1-1 Sewer System Management Plan
City of West Sacramento
Element 1
1 Sewer System Management Plan Goals and Introduction
This is the Sewer System Management Plan (SSMP) for the City of West Sacramento (City). The goals and intent of this plan are to document and improve upon the work this City does to properly operate and maintain its sanitary sewer system. By having this SSMP, the third update which the City has adopted, the City is showing its commitment to reducing and preventing spills and mitigating spills that could not be stopped.

1.1 Regulatory Context
The City owns and operates a sanitary sewer system for the benefit of its citizens, businesses, and commercial and industrial customers. Zoning is shown in Figure 1-1 and Table 1-1. For the protection of those formerly mentioned, the protection of the environment, and for the sake of protecting the sewer system infrastructure, the City implements an operation and maintenance program that is supported by the City budget, City Council, City Department of Public Works, the City’s Environmental Services Division, and community at large.

The City has codified requirements in their municipal code to provide rules and regulations for the use, design and construction of sanitary sewer facilities within the City. Qualified professionals on City staff and contractors hired by the City perform the work to oversee the construction, use, and maintenance of the sewer system.

The City developed this SSMP and applied for coverage under the Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems (WQ 2022-0103-DWQ). The General Order regulates sanitary sewer systems designed to convey sewage including, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure. This is important because compliance with the General Order requires good management practices that result in protecting citizens, businesses and the environment.

As the centerpiece for compliance with the General Order, this SSMP update is the City’s documentation of it’s commitment to maintaining a safe and effective SSMP. This is the third SSMP update. The original SSMP was adopted in 2008, revised in 2015, and revised again in 2018. The City’s audit in January 2025 (due 2/2/2025) and the recent Sewer Master Plan support this SSMP update. This updated SSMP (due 8/2/2025) continues to guide the City to:
• Properly manage, operate, and maintain the collection system. • Minimize the frequency of sanitary sewer spills
• Mitigate the impact of spills.
• Maintain a list of team members that have roles associated with maintaining the sanitary sewers.

GO SSMP Element 1.1.

The Plan Introduction section must provide a general description of the local sewer system management program and discuss Plan implementation and updates.
233

1.2 Sewer System Management Plan Update Schedule
The City Will update this manual as the need arises outside the formal regulatory deadlines: Such updates will occur when:
• Key personnel changes,
• Reporting process changes,
• In reaction to an audit,
• Any action needed to amend the 11 required elements.

The City views the SSMP as a living document needing periodic reconsideration, as required by the General Order. In this revised SSMP, the list of team members has been updated, as well as all the 11 elements. This update benefits from the recent SSMP Audit that occurred in January 2025 (Appendix C) and a recent Sewer Master Plan conducted in 2024 (Appendix F). The audit recommendations were used to guide this update and can be found in Appendix C.

The last audit and this SSMP are the beginning of the next SSMP six-year cycle. At a minimum, the schedule going forward for the coming cycle is estimated as follows:
• Annual Report/SSORP Review February 1, 2026
• Annual Report/ SSORP Review February 1, 2027
• 3-year audit: August 2, 2028
• Annual Report/ SSORP Review February 1, 2028
• Next SSMP Minor Update February 1, 2028
• Annual Report/ SSORP Review February 1, 2029
• Annual Report/ SSORP Review February 1, 2030
• 3-year audit: August 2, 2031
• Annual Report/ SSORP Review February 1, 2031
• 6-year SSMP revision: August 2, 2031
Updates, audits and modifications can be done more frequently, depending upon need and circumstances. The above dates are recommended as the minimum for keeping the SSMP a living document.

Internal audits are not required to be exhaustive. Instead, they are intended as a light review to incorporate staffing, equipment, and other changes that have occurred since the last audit required by the General Order. The result of those internal audits is a minor SSMP update.

GO SSMP Element 1.2.

The Plan Introduction section must include a schedule for the Enrollee to update the Plan, including the schedule for conducting internal audits. The schedule must include milestones for incorporation of activities addressing prevention of sewer spills

1.3 Sewer System Asset Overview
The City encompasses a total area of 14,722 acres, approximately 23 square miles, with about 1.4 square miles covered by water. Located in Yolo County, California, the City is bordered by the City of Sacramento to the north and east, separated by the Sacramento River, which also serves as the County line. West and south of the City are unincorporated agricultural lands, with the western boundary being the Yolo Bypass Wildlife Area.

West Sacramento’s population in 2020 was estimated at 53,915, with projections suggesting a rise to 79,478 by 2035. The City's land use is guided by the 2015-2035 General Plan, with future developments expected to concentrate in Southport and riverfront areas. The City's growth forecasts predict an annual population growth rate of 2.5%, leading to significant new housing and non-residential developments. The general Plan also outlines the City's ability to add up to 30,916 new housing units and 23.6 million square feet of non-residential space at full buildout, primarily focused in specific plan areas like the Washington and Bridge Districts The City’s wastewater collection system (please see Figure 1-2) includes approximately 164 miles of gravity sewers with sizes ranging from 4 to 30 inches in diameter, 30 miles of pressure pipelines, 9 pump stations, and 5 lift stations. It serves nearly all areas within the City limits, except for a small southeastern rural area relying on septic systems. The portion of the sewer system south of the Deep-Water Channel is newer, with the system north of the Deep-Water Channel being older. The system directs wastewater to the Lower Northwest Interceptor (LNWI), a 120-inch pipeline that ultimately leads to the Sacramento Regional Wastewater Treatment Plant. The City does maintain the lower sewer laterals and provides maintenance and repair of sewer laterals, installing cleanouts when needed.

GO SSMP Element 1.3.

The Plan Introduction section must provide a description of the Enrollee-owned assets and service area, including but not limited to:
• Location, including county(ies);
• Service area boundary;
• Population and community served;
• System size, including total length in miles, length of gravity mainlines, length of pressurized (force) mains, and number of pump stations and siphons;
• Structures diverting stormwater to the sewer system;
• Data management systems.
• Sewer system ownership and operation responsibilities between Enrollee and private entities for upper and lower sewer laterals;
• Estimated number or percent of residential, commercial, and industrial service connections; and • Unique service boundary conditions and challenge(s).

Additionally, the Plan Introduction section must provide reference to the Enrollee’s up to-date map of its sanitary sewer system, as required in section 4.1 (Updated Map of Sanitary Sewer System) of this Attachment 238
Element 1 Sewer System Management Plan Goals and Introduction June 2025 1-7 Sewer System Management Plan
City of West Sacramento
Of the collection system gravity mains, 74.9% are 8-inch diameter or smaller. The primary sewer materials are vitrified clay pipes (VCP) and polyvinylchloride (PVC) pipes, with plastic materials used for newer sewer construction and rehabilitation. The earliest installation date of gravity mains in the system database is 1945, although some pipes with unknown dates may predate 1945. Approximately 26% of gravity mains were constructed in the 1950s or earlier, with approximately 38% being constructed between the 1960s and 1990s, and over 35% being constructed in the 2000s or later. Force mains in the system are composed primarily of ductile iron pipes (DIP) and PVC pipes.

Recent updates to the City’s and Computerized Maintenance Management System have helped provide detailed information about the infrastructure, allowing more accurate assessments of system components, including pipe diameters, materials, and installation years. Pump station asset information and work order history is currently managed by the City using a Computerized Maintenance Management System (CMMS). The City has a list of the IDs of assets currently included in CMMS, making tracking and accounting of them relatively easy. Pump station asset information and work order history is currently managed by the city using a Computerized Maintenance Management System (CMMS).

The City is in the process of improving its Geographic Information System (GIS) inventory of the collection system linear assets and maintenance holes. Its GIS-based registry includes asset information such as material, diameter, length, installation date, and a unique numerical identifier. In recent years, assets in the northern portion of the City have been surveyed and added to the registry. The City’s GIS is divided into Geospatial and Schematic portions and is shown in the City of West Sacramento Sewer Map Book (Appendix A).

The Geospatial portion of the GIS generally contains detailed hydraulic attributes (pipeline diameter and invert elevations) and location information for the collection system assets. The Schematic GIS contains general asset location information, such as pipe material and diameter, but does not include all other GIS attributes. The City’s Geospatial geodatabase of sewer GIS data was expanded to include data that was previously only available in the Schematic GIS dataset. The City completed an update in July 2023 that added a significant number of pipes to the Geospatial geodatabase. The City continues to update the GIS database. Many of the City’s gravity mains are not included in the Geospatial geodatabase. Currently, pipes in the Schematic GIS are merged with the Geospatial GIS layer. The Schematic GIS “year installed” attribute was estimated based on an approximate year of the neighboring development and installation date of nearby pipes with known installation dates. The City uses a GIS Correction form for field staff that notice locations that do not match the GIS mapping effort. This level of QA/QC grounds the data confirmed on the GIS map.

The City of West Sacramento is the responsible entity for all stormwater-related conveyances. All internal drainage within the City is collected through gravity storm drains and drainage canals and conveyed by a series of pump stations into either the Sacramento River, the Deep Water Shipping Channel (DWSC), or the Yolo Bypass. The Storm Drain Network Map for the City of West Sacramento is included in Element 4, as required. 239

3 Legal Authority

3.1 Municipal Code
The City has the legal authority to own and operate its sanitary sewer collection system. The West Sacramento Municipal Code establishes this legal authority and is available online (http://qcode.us/codes/westsacramento/).

That authority is specifically contained within Title 13, Chapter 8 and Chapter 9 of the Municipal Code and addresses the listed sections summarized in the GO and listed in Table 3-1.

GO SSMP Element 3.

The Plan must include copies or an electronic link to the Enrollee’s current sewer system use ordinances, service agreements and/or other legally binding procedures to demonstrate the Enrollee possesses the necessary legal authority to:
• Prevent illicit discharges into its sanitary sewer system from inflow and infiltration (I&I); unauthorized stormwater; chemical dumping; unauthorized debris; roots; fats, oils, and grease; and trash, including rags and other debris that may cause blockages;
• Collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure;
• Require that sewer system components and connections be properly designed and constructed; • Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the Enrollee;
• Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures; and
• Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

3.2 Cooperation, collaboration and Easement Agreements for Accessibility The City does not have any tributary or satellite sewer systems connected to its gravity or force main sewer collection system according to the definition of the WDR. So, the City does not need any additional agreements for satellite sewer systems. Similarly, the City owns and operates the storm sewers within the City service area. They, therefore, do not need any agreements for the stormwater conveyance system.

However, the City is a satellite agency to the Sacramento Regional County Sanitation District (Regional San).

Regional San is responsible for operating and maintaining the interceptor sewer system to which the City’s collection systemdischarges to for transport to the regional wastewater treatment plant located southeast of the City near Elk Grove, California. The City is responsible for all collection system facilities up to the point of connection to the interceptor sewer. The City maintains communication with Regional San and the two agencies support emergency response efforts within each other’s systems “to the extent that staff in one agency can help the other agency without jeopardizing the functioning of their own systems” (Wastewater Operating Agreement Between the Sacramento Regional County Sanitation District and the City of West Sacramento) 250

The sewer collectionmaps allow utility crews to determine and locate components, sewer force main and gravity flow directions, pump station locations, and collection system service areas, manhole and valve locations, transition structure and manifold locations, and upper and lower lateral connection locations.

The storm water maps (Figure 4-1) allow crews to determine gutter and pipe flow direction, storm water inlet locations, ditch and drain locations, pump station locations and their drainage-shed areas. The sewer collection, storm water, and water servicemaps are in separate binders using a common grid system. This allows for side by side comparison of a specific area that may be impacted by a spill event.

Figure 1-3 shows gravity segments, pressure segments, and the pump stations of the collection system. Appendix A includes a map book of the complete collection system with more detail, such as valves, manholes, and pipe diameters where such information is available in Geographic Information System (GIS). The GIS is still being updated. Please see Element 1-3 for more discussion regarding the GIS program in the City.

4.2 Preventive operation and Maintenance Activities

4.2.1 CLEANING AND MAINTAINING SEWER SYSTEM COMPONENTS
The scheduling and data collection system for preventive operation and maintenance activities is contained in the City’s sewer system O&M Program. The elements of the City’s sewer system O&M Program include:
• Correctivemaintenance of gravity sewers;
• CCTV inspection program to determine the condition of the gravity sewers; • Rehabilitation and replacement of sewers that are in poor condition; and • Periodic inspection and preventive maintenance for the lift stations and force mains • Documentation of finding and work performed into CMMS.

Force main alignments are inspected on an annual basis, and discharge locations surveyed for possible damage and corrosion from the release of hydrogen sulfide when the force mains discharge to the gravity collection system.

Figure 4-2 shows the City’s cleaning plan that prioritizes to clean the areas of the system with the highest risk of spill first, including City-identified maintenance “hot-spots”. These “hot spots” need to be part of the routine maintenance program requiring O&M frequencies appropriate for each specific “hot spot”.

Based on observation and collected data, The City has developed a 5-year preventativemaintenance cleaning and inspection programfor all gravity sewer mains. This program includes high pressure flushing of the gravitymain followed by closed circuit television (CCTV) inspection. In “hot spot” areas, the CCTV inspections are recommended every 1-3 years. The City also provides corrective maintenance, which is typically the result of service calls from staff or the public. Quick response from Collections staff often prevent potential spills from occurring, since staff can often clear blockages before a spill occurs. Collections staff can also minimize the impact GO SSMP Element 4.2.

A scheduling system and a data collection system for preventive operation and maintenance activities conducted by staff and contractors.

The scheduling system must include:
• Inspection and maintenance activities.
• Higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems.
• Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes.

The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure. 254

City of West Sacramento
entire collection system within the next five years. As of December 2023, the City has cleaned 75.7 miles, or

46.6%, of the gravity mains since the 2017 Master Plan, including most of the gravity mains identified as Priority 1 or 2. During the cleaning process, City staff identified approximately 3,200 feet as blocked, 2,100 feet as damaged, and 25,900 feet as having grease accumulation.

4.2.3 FORCE MAINS
Force mains are currently maintained as problems are identified. A prioritized and focused force main inspection program and preventative maintenance program should be developed in the next five years. City staff has indicated that the preventative maintenance program should initially focus on identification of “hot spots” and regular maintenance for the air relief valves and blow off valves along the force main alignment.

Table 4-1 lists forcemain asset information.Many of the forcemains were installed at the time of the original construction of the associated lift stations. Each of the pump stations discharge to a common forcemain that flows to a transition structure and then north of the Deep Water Channel to the CommonManifold near Southport PS and then discharges to the LNWI. The lengths of this shared force main are shown in Table 4-3 as “Common Force Main.

using the PMC2000 Computerized Maintenance Management System (CMMS). Staff in the Utilities Maintenance and Maintenance divisions perform the tasks described on the preventative maintenance work order (PM). These PMs describe the work that is to be done to the pump stations associated structural, mechanical, and electrical infrastructure and equipment. The frequency of a PM is determined by manufacturer’s recommendations and/or a combination of experience and is intended to extend the life of equipment and to prevent equipment failure. The frequency of these inspections is listeded in Table 4-3. Pump station asset information and work order history is currently managed by the City using a Computerized Maintenance Management System (CMMS). The City has a list of the IDs of assets currently included in CMMS, making tracking and accounting of them relatively easy. 258

4.2.4 PRIVATE SEWER LATERALS
The City is responsible for the operation, repair or replacement of private sewer laterals below the cleanout and the connection to theCitymains. If the connection owner has no cleanout, they can be held responsible for its maintenance for the entire length of the cleanout. However, the City has historicallymaintained those systems too, installing a cleanout above the lower lateral, which includes the portion of the lower lateral from the cleanout at the property line to the City main. The City will continue to install new cleanouts as needed to facilitate cleaning and inspection equipment.

On commercial properties, laterals are the sole responsibility of the property owner.

4.2.5 REHABILITATION AND REPLACEMENT PROGRAM

4.2.5.1 Gravity Sewer.

The City is currently rehabilitating or replacing gravity sewer infrastructure to correct a backlog of condition defects, and/or as a part of other regional improvements. Now that the City has collected CCTV data for a portion of its system, it is time to assess that data for rehab/replacement needs in the coming year.

After CCTV inspection has been completed, rehab/replacement projects can be scoped, and sewers can be assigned a cleaning and inspection frequency appropriate for the maintenance and structural defects observed. In the past, City staffing and equipment resources have been too constrained to both systematically clean and inspect the system, so contractor support is needed.

4.2.5.2 Pump Stations.

The City has begun expanding its pump station capacity by starting with the South Pump Station Capacity Improvement Project, which also includes converting the wet pit/dry pit station to a submersible station. Condition upgrades have been recommended in the Sewer Master Plan (Appendix F) and are summarized in Table 9-4. of the Sewer Master Plan.

4.3 Training
The City provides regular technical, skill, and safety training to Public Works staff. The City is working on annual sanitary sewer spill training that includes developing spill response scenarios that will use the Sanitary Sewer Overflow Response plan and spill estimation procedures. This training will be in addition to professional training that the City provides through APWA, CWEA and other contractor-provided training. On an as needed basis, relevant DS staff will attend CWIQS training, as it comes available.

GO SSMP Element 4.3.

In-house and external training provided on a regular basis for sanitary sewer system operations and maintenance staff and contractors. The training must cover:

The requirements of this General Order;
The Enrollee’s Spill Emergency Response Plan procedures and practice drills; Skilled estimation of spill volume for field operators; and Electronic CIWQS reporting procedures for staff submitting data. 261
Element 4 Operation and Maintenance Program

City of West Sacramento
Training is documented in the Public Works training database. Safety elements and operation and maintenance practices are established in the Public Works Utility Maintenance/Maintenance Division’s Standard Operating Procedures (SOP). New SOP’s or updates to current SOP’s are stored in a computer file and made available in a SOP document binder. The City will require contractors to verify their employee training program.

4.4 Equipment Inventory

4.4.1 CONTINGENCY EQUIPMENT AND REPLACEMENT INVENTORIES The City’s corporation yard provides a central location for the Public Works Utility Maintenance/ Maintenance Division’s housing and storage of bulk materials, equipment, and parts used for routine tasks and emergency situations. Material, equipment, and spare part inventories are monitored and maintained by division staff. A CMMS tracks equipment in the system.

5 Design and Performance Provisions

5.1 Updated Design Criteria and Construction Standards and Specificaions The City’s Sanitary Sewer Design Standards, Standard Plans, and Standard Specifications for sewer main lines, structures and appurtenances like maintenance holes, lift stations, and service laterals (lower laterals) are administered by the Development Engineering Division.

5.1.1 GENERAL
The City has established standards for both new construction and renewal and replacement work associated with the collection system. These standards are periodically reviewed and revised by the Development Engineering Division. Complete versions of the City's Standard Specifications and Details are located on the City's website at:
www.cityofwestsacramento.org/city/depts/comdev/engineering/specs/default.asp.

5.1.2 2024CITY SEWER MASTER PLAN UPDATE
The 2024 City Sewer Master Plan evaluated the sewer collection system using hydraulic model. The City’s sewer system hydraulic model was developed using Innovyze® InfoWorks™ ICM software. The model was originally developed in the 2017 Master Plan, and updated with the latest GIS data, as-built information, and field data collected in 2023. Using the model, the Sewer Master Plan identified capacity issues, including both gravity mains and pump stations. The need to address those issues have been incorporated into the CIP recommendations to address system upgrades. Proposed sewer improvements were tested in the model to confirm that they would eliminate the identified capacity deficiencies and to confirm that sewers and pump stations downstream of the upsized pipes could handle the higher peak flows.

The work done in the 2024 Sewer Master Plan satisfies the Element 5.1 of the 2022 GO modifications addressing Design and Performance Provisions.

GO SSMP Element 5.1.

Updated design criteria, and construction standards and specifications, for the construction, installation, repair, and rehabilitation of existing and proposed system infrastructure components, including but not limited to pipelines, pump stations, and other system appurtenances. If existing design criteria and construction standards are deficient to address the necessary component-specific hydraulic capacity as specified in section 8 (System Evaluation, Capacity Assurance and Capital Improvements) of this Attachment, the procedures must include component-specific evaluation of the design criteria.

5.1.3 LIFT STATIONS
All lift stations are required to be designed and constructed to conform to the City’s Wastewater Pump Station Design Standards, which are maintained by the Community Development Division and which are available from the City. In the 2024 Sewer Master Plan, all lift stations were assessed for hydraulic capacity, including future needed capacity. Those that were found insufficient are included to upgrading in the CIP.

5.1.4 CITY SEWER SYSTEM –AUTHORIZED PIPE MATERIALS
The authorized materials that are currently accepted in the City Sewer System are shown in the City’s Standard Specifications and Details.

Laterals must be of the same material type and designation as that used for the main sanitary sewer pipe.

5.1.5 PRIVATE SEWER SYSTEMS AND PRIVATE LATERALS
All private sewer systems and private sewer laterals are required to be designed, installed, inspected and accepted per the requirements for sewers in Division 1, Section 5 and Division IV, Section 14 of the Standard Specifications except for the following modifications:
• The minimum size of any on-site sanitary sewer main shall be four inches in diameter; • Pipe depth to finish grade and/or subgrade must be in conformance with the specifications of the pipe manufacturer; and
• All on-site sanitary sewer manholes shall be constructed in accordance with the Standard Details.

There are no City requirements for the spacing of on-site sanitary sewer manholes. However, future maintenance and accessibility should be considered. All Sanitary Sewer Design Calculations shall be signed and stamped by a California registered civil engineer prior to approval by the City.

5.2 Procedures and Standards
The City’s Wastewater Collection System inspection and testing criteria are documented in the Standard Specifications and Details, and include:

5.2.1 NEW AND REHABILITATED GRAVITY SEWERS

5.2.2 DESIGN
Engineering calculations to support the sewer system design shall be submitted to the City Engineer for approval.

5.2.2.1 Leakage
Sewer mains must be tested following Standard Specifications Division IV, Section 14.03D Testing of Sewer Lines. After acceptance of the street subgrade and/or trench backfill all gravity sewers must pass a low-pressure air test in the presence of the City Engineer conducted in accordance with the Standard Specifications. If the installation fails to meet this requirement, the Contractor shall, at his own expense, determine the source of leakage. He shall then repair or replace all defective materials and/or workmanship and perform the air test as many times as necessary to achieve an acceptable test.

5.2.2.2 CCTV Inspection
Prior to acceptance of any sanitary sewer line by the City, all six-inch and larger lines shall be inspected internally by television in the presence of the City Engineer as outlined in Division IV, Section 14.03D Testing of Sewer Lines at the Contractor’s expense. Defects such as high and low spots, joint separations, offset joints, chipped ends, cracked or damaged pipe, infiltration points and debris in lines shall be corrected by the Contractor, at his expense.

5.2.3 NEW AND REHABILITATED MANHOLES

5.2.3.1 Inspection during Construction
All new gravity sewers will be periodically inspected during construction to ensure that the sewer is constructed using the specified materials and methods. All sewer line connections to manholes, trunk sewers, main sewers, or side sewers shall be left uncovered until after the inspection has been made.

5.2.3.2 Leakage
Sewer mains and manholes will be tested following Standard Specifications Division IV, Section 14.03D Testing of Sewer Lines. All sewer manholes must pass a vacuum test performed by the Contractor after installation of the manhole but prior to placement of trench backfill. If a manhole fails the vacuum test, repairs shall be made with mortar while the vacuum is still being drawn. Retesting shall proceed until a satisfactory test is obtained.

268
Element 6 Spill Emergency Response Plan
June 2025 6-2 Sewer System Management Plan
City of West Sacramento

6.1 Purpose
The purpose of the City’s Sanitary Sewer Overflow Response Plan (SSORP) (Appendix B) is to provide procedures to effectivelymanage the response and the remediation of a spill when it occurs in an effort to protect public health as well as the environment. The SSORP provides guidelines for City personnel to follow in responding to, cleaning up, and reporting spills that may occur within the City’s service area. This SSORP satisfies the SWRCB Statewide General Waste Discharge Requirements (GWDR), which require wastewater collection agencies to have an Overflow Emergency Response Plan.

6.2 Policy
The City’s employees are required to report all wastewater overflows resulting from the Cityowned/maintained sanitary sewer system found and to take the appropriate action to secure the wastewater overflow area, properly report to the appropriate regulatory agencies, relieve the cause of the overflow, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City’s goal is to respond to sewer system overflows as soon as possible following notification. The City will follow reporting procedures in regard to sewer spills as set forth by the Central Valley Regional Water Quality Control Board (CVRWQCB) and the California State Water Resources Control Board (SWRCB).

6.3 Goals
The City’s goals with respect to responding to spills are:
• Work safely;
• Respond quickly to minimize the volume of the spill;
• Eliminate the cause of the spill;
• Prevent sewage system overflows or leaks from entering the storm drain system or receiving waters to the maximum extent practicable;
• Contain the spilled wastewater to the extent feasible; • Minimize public contact with the spilled wastewater;
• Mitigate the impact of the spill;
• Meet the regulatory reporting requirements;
• Evaluate the causes of failure related to certain spills; and • Revise response procedures resulting from the debrief and failure analysis of spills.

6.4 Spill Detection and Notification
The processes that are employed to notify the City of the occurrence of an spill include: observation by the public, receipt of an alarm, or observation byCity staff during the normal course of their work.

TheCity operateswastewater pump stations. In the event of any pump failure, the high level sensor activates the SCADA alarm system and the City is contacted. To prevent overflow, wastewater fromthe wet well can either be pumped into a vacuumtruck for disposal to a nearby sanitary sewer manhole, or bypassed around the station into the sanitary sewer system. Each pump station has an emergency response plan that can be followed in the event of a pump failure.

City of West Sacramento

6.4.1 PUBLIC OBSERVATION
Public observation is the most common way that the City is notified of blockages and spills. Once the initial call is made reporting the spill, the report is dispatched to the Chief UtilityMaintenance Worker during normal working hours or to theOn-call UtilityMaintenance Worker after hours for response. The responding employee is responsible for determining whether additional city personnel are necessary to aid in containment, clean-up and remediation.

NormalWorkHours. Customers can report sewer problems by telephone at 916-617-4850 during normal working hours (Monday through Friday from 8:00 am to 4:30 pm). The office staff takes the call and notifies the Chief Utility Maintenance Worker.

After Hours. After hours, the Public Works phone system redirects incoming phone calls to 916-617-4850 to the Dispatch Center or this center can be called directly at 916-372-3375. The Dispatch Center will notify the On-call Utility Maintenance Worker.

If an spill occurs within the portion of the sanitary sewer collection system maintained and operated by the Sacramento Regional County Sanitation District the City contacts Sacramento County Central at 916-875-5000.

When calls are received, either during normal work hours or after hours, the individual receiving the call will collect the following information:
• Time and date of call;
• Specific location of potential problem;
• Nature of call;
• In case of spill, estimated start time of overflow;
• Caller’s name, address and telephone number;
• Caller’s observation (e.g., odor, duration, location on property, known impacts, indication if surface water impacted, appearance at cleanout or manhole); and • Other relevant information.

The City’s Public Works Department will be responsible for establishing a communication center in the event of a Category 1 spill. The communication center will consist of one of the following Public Works employees:
• Public Works Operations Manager;
• Utilities Maintenance Superintendent;
• Chief Utilities Maintenance Worker; and
• Public Works Senior Clerk.

The designated employee will be stationed at a predetermined location within the Public Works Administration building. The communication center will be the direct line of communication with outside regulatory and emergency agencies as well as responding city crews.

6.5 City Staff Observation
City staff conducts periodic inspections of its sewer system facilities as part of their routine activities. Any problems noted with the sewer system facilities are reported to appropriate City staff that, in turn, responds to emergency situations. Work orders are issued to correct non-emergency conditions.

6.6 Contractor Observation
The following procedures are to be followed in the event that contractor/plumber causes or witnesses a spill. In the contractor/plumber causes or witnesses an spill they should:
• Immediately notify the City at 916-617-4850;
• Protect storm drains;
• Protect the public;
• Provide information to the Chief Utility Maintenance Worker or On-call Utility Maintenance Worker such as start time, appearance point, suspected cause, weather conditions, etc; and
• Direct ALL media and public relations requests to the Communications and Media Office, at 916-617-4516, who will provide the media with all relevant information.

Element 6 Spill Emergency Response Plan
June 2025 6-7 Sewer System Management Plan
City of West Sacramento
• To follow safe work practices;
• To respond promptly with the appropriate and necessary equipment or call for additional staff assistance;
• To contain the spill wherever feasible;
• To restore the flow as soon as practicable;
• To minimize public access to and/or contact with the spilled sewage; • To promptly notify the Supervisor in event of major spill; • To return the spilled sewage to the sewer system;
• To restore the area to its original condition (or as close as possible); and • To photograph or video field conditions of the spill.

6.7.3 SAFETY
The first responder is responsible for following safety procedures at all times. Special safety precautions must be observed when performing sewer work. There may be times when City personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before starting the job.

6.7.4 INITIAL RESPONSE
The first responder must respond to the reporting party/problem site and visually check for potential sewer stoppages or overflows.

The first responder will:
• Note arrival time at the site of the overflow/backup. • Verify the existence of a sewer system spill or backup. • Determine if the overflow or blockage is from a City-owned/maintained or private sewer. • Identify and assess the affected area and extent of spill. • Contact caller if time permits.
• If the spill is large or in a sensitive area, document conditions upon arrival with photographs. Decide whether to proceed with clearing the blockage to restore the flow or to initiate containment measures.

The guidance for this decision is:
• Small spills (i.e., spills that are easily contained) – proceed with clearing the blockage. • Moderate or large spill where containment is anticipated to be simple – proceed with the containment measures.
• Moderate or large spills where containment is anticipated to be difficult – proceed with clearing the blockage; however, whenever deemed necessary, call for additional assistance and implement containment measures.
• Take steps to contain the spill. For detailed procedures refer to the Sanitary Sewer Overflow Response Plan/Backup Response Packet, included as Appendix B to this report.

In the event of a failure on a sewermain line, sewer forcedmain, pump station or any other portion of the sanitary sewer collection system, it may be necessary to notify upstream industrial dischargers of the situation and request that they reduce their sewer discharge. Additionally, some sanitary sewer pump stations are fed by other sanitary 274
Element 6 Spill Emergency Response Plan
June 2025 6-8 Sewer System Management Plan
City of West Sacramento
sewer pump stations within the system. In these cases, upstream pump stations will need to be turned off so repairs can bemade. Continuous monitoring of pump station wet well levels shall be conducted to ensure that the capacity is sufficient for the time the pump station is off. Large failures may require an extended amount of time for repair. Bypass pumping (manhole to manhole) and/or mobile sewage collection may be necessary with prolonged repair. If necessary, City staff will coordinate with commercial septage haulers for assistance. A listing of septage haulers is shown in Table 6-1.

G&C Septic Tank Service 916-366-1111 Galt, 28 miles from City Yolo Pumping Services, Inc. 530-662-5534 Woodland, 19 miles from City

6.7.5 INITIATE SPILL CONTAINMENT MEASURES
When an spill occurs, all feasible steps must be taken to prevent impacts including controlling or limiting the amount of wastewater to the storm drain system, terminating the discharge and recovering and properly disposing of as much of the spill as possible including wash down water that is used. Standard Operating Procedures (SOPs) have been developed and implemented covering cleanup and remediation of spills. These SOPs are found in Appendix B.

The first responder will attempt to contain as much of the spilled sewage as possible using the following steps:
• Determine the immediate destination of the overflowing sewage; • Plug storm drains using air plugs, sandbags, and/or plastic mats to contain the spill, whenever appropriate. If spilled sewage has made contact with the storm drainage system, attempt to contain the spilled sewage by plugging downstream storm drainage facilities; • Contain/direct the spilled sewage using dike/dam or sandbags; and • Pump around the blockage/pipe failure.

For detailed procedures refer to the Sanitary Sewer Overflow Response Plan/Backup Response Packet, included as Appendix B to this Plan.

6.7.6 RESTORE FLOW
Using the appropriate cleaning equipment, the responding crew will set up downstream of the blockage and hydroclean upstream from a clear manhole. Attempt to remove the blockage from the system and observe the flows to ensure that the blockage does not reoccur downstream. If the blockage cannot be cleared within a reasonable time from arrival, or sewer requires construction repairs to restore flow, then initiate containment and/or bypass pumping. If other assistance is required, immediately contact the Public Works OperationManager. For detailed procedures refer to the Sanitary Sewer Overflow Response Plan/Backup Response Packet, included as Appendix B.

6.7.7 EQUIPMENT
This section provides a list of specialized equipment that may be used to support this Overflow Emergency Response Plan:
• Closed Circuit Television (CCTV) Inspection Unit. A CCTV Inspection Unit is required to determine the root cause for all spills from gravity sewers.
• Camera. A digital or disposable camera is required to record the conditions upon arrival, during clean up, and upon departure.
• EmergencyResponse Trucks. A utility body pickup truck, or open bed is required to store and transport the equipment needed to effectively respond to sewer emergencies. The equipment and tools will include containment and clean up materials.
• Portable Generators, Portable Pumps, Piping, and Hoses. Equipment used to bypass pump, divert, or power equipment to mitigate an spill.
• Combination Sewer Cleaning Trucks. Combination high velocity sewer cleaning trucks with vacuum tanks are required to clear blockages in gravity sewers, vacuum spilled sewage, and wash down the impacted area following the spill event.
• Air Plugs, Sandbags and Plastic Mats
• Portable Lights

6.8 Recovery and Cleanup
The recovery and cleanup phase begins immediately afterthe flow has been restored and the spilled sewage has been contained to the extent possible. The spill recovery and cleanup procedures are:

6.8.1 ESTIMATE THE VOLUME OF SPILLED SEWAGE
Use the methods outlined in Appendix B, and/or the Field Guide to estimate the volume of the spilled sewage.

Wherever possible, document the estimate using photos and/or video of the spill site before and during the recovery operation.

6.8.2 RECOVERY OF SPILLED SEWAGE
Vacuumup and/or pump the spilled sewage and rinse water, and discharge it back into the sanitary sewer system. 276
Element 6 Spill Emergency Response Plan
June 2025 6-10 Sewer System Management Plan
City of West Sacramento

6.8.3 CLEAN-UP AND DISINFECTION
Clean up and disinfection procedureswill be implemented to reduce the potential for human health issues and adverse environmental impacts that are associated with an spill event. The procedures described are for dry weather conditions and will be modified as required for wet weather conditions. Where cleanup is beyond the capabilities of the Field Crew, a cleanup contractor will be used. • Private Property. City crews are responsible for the cleanup when the property damage is minor in nature and is outside of private building dwellings, such as in front, side and backyards, easements, etc.

In all other cases, affected property owners can call a water damage restoration contractor to complete the cleanup and restoration. If the overflow into property is the definite cause of City system failure, the property owner can call out a water damage restoration contractor to complete the cleanup and restoration. In both cases, property owners may obtain a City claim form from the City Manager’s Office.

If an spill in the City’s maintained system resulted in a flooded home or structure the City’s insurance carrier will be the lead on any claims.
• Hard Surface Areas. Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water and/or Deozyme or similar non-toxic biodegradable surface disinfectant until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Take reasonable steps to contain and vacuum up the wastewater. Allow area to dry. Repeat the process if additional cleaning is required.
• Landscaped and Unimproved Natural Vegetation. Collect all signs of sewage solids and sewagerelated material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Either contain or vacuum up the wash water so that none is released.

Allow the area to dry. Repeat the process if additional cleaning is required. • Natural Waterways. The California Department of Fish and Wildlife will be notified by CalOES for spills greater than or equal to 1,000 gallons.
• Wet Weather Modifications. Omit flushing and sampling during heavy storm events (i.e., sheet of rainwater across paved surfaces) with heavy runoff where flushing is not required and sampling would not provide meaningful results.

6.13Post Spill Event Debriefing
Every spill event is an opportunity to evaluate the City response and reporting procedures. Each overflow event is unique, with its own elements and challenges including volume, cause, location, terrain, climate, and other parameters.

As soon as possible after Category 1 and Category 2 spill events all of the participants, from the person who received the call to the last person to leave the site, will meet to review the procedures used and to discuss what worked and where improvements could be made in preventing or responding to and mitigating future spill events.

The results of the debriefing will be documented including attendees, summary of discussions, action items identified and assignments and schedules for completion and tracked to ensure the action items are completed as scheduled.

6.14 Failure Analysis Investigation
The objective of the failure analysis investigation is to determine the “root cause” of the spill and to identify corrective action(s) needed that will reduce or eliminate future potential for the spill to recur or for other spills to occur.

The investigation will include reviewing all relevant data to determine appropriate corrective action(s) for the line segment. The investigation will include:
• Reviewing and completing the Sanitary Sewer Overflow Report and any other documents related to the incident;
• Reviewing the incident timeline and other documentation regarding the incident; • spill start time documentation;
• Reviewing communications with the reporting party and witness; • Reviewing volume estimate, volume recovered estimate, volume estimation assumptions and associated drawings and maps of the impacted area(s);
• Reviewing available photographs and video of the incident; • Interviewing staff that responded to the spill;
• Reviewing pastmaintenance records and SCADA records if utilized; • Reviewing past CCTV records;
• Conducting a CCTV inspection to determine the condition of all line segments immediately following the spill and reviewing the video and logs;
• Reviewing any Fats, Oils, Roots and Grease (FROG) related information or results; 284

7.1 Fog Source Control Program – Reviews & Inspections
The City Environmental Services Division developed a Food Service Establishment (FSE) FOG awareness and outreach activity to prevent FOG related spills. This activity involves visiting FSE in the City and distributing and explaining the FSE FOG Control Program Information kit. This kit is a trainingmodule designed for teaching FSE owners and employees about the proper disposal of FOG.

7.1.1 PUBLIC EDUCATION/OUTREACH
Public education and outreach remains an integral element of the FSE FOG Control Program. Outreach is provided to FSE staff and management. Public education of the general public is also a core element in the FOG GO SSMP Element 7.

The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed.

The procedures must include, at minimum:
• An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe-blocking substances;
• A plan and schedule for the disposal of pipe-blocking substances 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 substances generated within a sanitary sewer system service area; • The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, recordkeeping and reporting requirements;
• Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance; • An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above. 288

program and spill programs. Information can be accessed at: City of West Sacramento/FOG | City of West Sacramento. Information such as where the public can drop off their grease and cooking oil is available. In addition, the City has a “No Wipes in Pipes campaign to reduce sewage restrictions from masks, paper products, and other wipes.

7.1.2 APLAN AND SCHEDULE FOR THE DISPOSAL OF PIPE-BLOCKING SUBSTANCES The City provides for year-round collection and recycling of residential cooking oil and grease. The availability of this collection bin is advertised quarterly in the City’s publication called City Lights and as a footer on its sewer bills.

The collection bin is serviced by a local rendering company. The City prioritizes ‘hot spots’ for cleaning known problem areas in their cleaning schedule.

7.1.3 THE LEGAL AUTHORITY
Municipal Code 13.09, the City has legal authority to prohibit FOG discharges to the wastewater collection system, to establish requirements for grease removal devices, to inspect FOG producing facilities, and to carry out enforcement actions.

7.1.4 REQUIREMENTS TO INSTALL GREASE REMOVAL DEVICES
The City also requires, in Municipal Code Section 13.09.09, that an interceptor shall be installed at businesses where FOG is generated

7.1.5 INSPECTIONS
The City Environmental Services Division developed a Food Service Establishment (FSE) FOG awareness and outreach activity to prevent FOG related spills. This activity involves visiting FSE in the City and distributing and explaining the FSE FOG Control Program Information kit.

7.1.6 AN IDENTIFICATION OF SANITARY SEWER SYSTEM SECTIONS The City has identified the gravity sewer mains and laterals that have had recurring, excessive grease in the past.

The City cleans these mains as part of a routine maintenance program primarily to prevent FOG blockages before they occur. The City reviews the results of these practices to determine if FOG mitigation through preventative maintenance is adequate and acceptable

Element 8 System Evaluation, Capacity Assurance and Capital Improvements June 2025 8-1 Sewer System Management Plan
City of West Sacramento

8.2 Capacity Assessment and Design Criteria
In the 2024 Sewer Master Plan, the City used a model that was originally developed in the 2017 Master Plan, and updated with the latest GIS data, as-built information, and field data collected in 2023. Such information includes inspection spill history, and other data. Additionally, the hydraulic parameters for the City’s pump and list stations were revised to reflect current conditions, including updated to recently replaced facilities. To calculate sewer loads, the wastewater service area was divided into 266 sub-catchments. Wastewater flows were categorized into base wastewater flow (BWF), rainfall-dependent inflow and infiltration (RDII), and groundwater infiltration (GWI) and assigned to each node in the hydraulic model.

To calibrate the model, flow monitoring was performed at 8 sites over 48 days from January 6, 2023, to February 22, 2023, at 15-minute intervals. Precipitation data was downloaded from four Weather Underground stations at GO SSMP Element 8.2.

The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for: • Dry-weather peak flow conditions that cause or contributes to spill events;
• The appropriate design storm(s) or wet weather events that causes or contributes to spill events; • The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.

The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change;
• Increases of erosive forces in canyons and streams near underground and aboveground system components due to larger and/or higher-intensity storm events; • Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities. 293

15-minute intervals. For dry weather flow calibration, BWF was developed using industry-standard unit flow factors and GWI was estimated using industry-standard empirical formulas. The unit flow factors, diurnal patterns, and allocations between BWF and GWI were adjusted until the modeled average dry weather flow (ADWF) and peak dry weather flow (PDWF) base wastewater flow (BWF) were within ten percent of measured data in every metered sewer basin. For wet weather flow calibration, RDII was calculated using the rainfall/time/recession (RTK) method.

The Wastewater Planning Users Group (WaPUG) criteria were used to determine a good match between observed and predicted data for peak flow, volume, and depth. The results are incorporated herein in Appendix F.

8.3 Prioritization or Corrective Action
The City’s 2024 City of West Sewer Master Plan Asset Management Plan has been developed and uses a riskbased approach to prioritize necessary improvements and outlines triggers for when maintenance or upgrades are required. The City’s level of service, as established in the 2017 Master Plan, focus on maximizing efficiency, extending infrastructure life, and ensuring regulatory compliance by eliminating spills. Maintenance activities are managed proactively through scheduled repairs and the use of the PMC2000 system to track pump station assets and work orders. This system was updated in the new Master Plan. Additionally, the City is updating its inventory of linear assets and maintenance holes using the GIS registry.

To further enhance the collection system, the City has developed a preventative maintenance program focusing on routine cleaning, inspections, and repairs. A significant effort is underway to clean and inspect gravity mains, with 46.6% of the system already completed since the 2015 Master Plan. The program also includes plans for pump station rehabilitation and force main maintenance. Additionally, the City is addressing a backlog of condition defects in gravity sewers and expanding pump station capacity starting with the South Pump Station Capacity Improvement Project.

8.4 Capital Improvement Plan
GO SSMP Element 8.4.

The capital improvement plan must include the following items:

Project schedules including completion dates for all portions of the capital improvement program; Internal and external project funding sources for each project; and Joint coordination between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects; and Interagency coordination with other impacted utility agencies.

GO SSMP Element 8.3.

The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills. 294
Element 8 System Evaluation, Capacity Assurance and Capital Improvements June 2025 8-3 Sewer System Management Plan
City of West Sacramento
The City prepares an annual list of capital improvement projects that includes projects to address recently identified wastewater collection system capacity issues. Engineering staff prioritize and select the projects to be included on the annual list.

As a part of the 2024 Sewer Master Plan, the City developed a Capital Improvement Project (CIP) to complete rehabilitation and replacement of collection system assets, as identified through the 2015 Sewer Master Plan. The CIP program has not been incorporated to date. It is expected to be considered after a rate study has been conducted to determine which projects can be funded, incorporated into the 2015 CIP. The 2024 Sewer Master Plan contains the list of objects that the City should consider for the CIP. The 2025 Sewer Master Plan is incorporated herein (Appendix F).

8.5 Implementation
Please see the projects listed in the 2024 Sewer Master Plan (Appendix F).

8.6 Resilience
Element 8 builds resilience by assessing sewer capacity, identifying I/I and planning for future CIP that are risk based and hydraulicly assessed.

Element 9
9 Monitoring, Measurement and Program

9.1 Performance Measures
Effectiveness of a SSMP element in reducing spill’s will be measured by defining, tracking, and evaluating performance indicators for each appropriate element. Each element in the SSMP is intended to contribute to improving the overall program; to cease spills that can be avoided; to respond to those spills that occur, and to manage materials that are naturally the result of owning and operating a municipal sewer. The indicators that the City will use to measure the performance of its wastewater collection system and the effectiveness of its SSMP are:
• Spills: Total number, Number for each cause (roots, grease debris, pipe failure, capacity, lift station failures, and other), spill rate (#/100 miles/year);
• Portion of sewage recovered compared to total volume spilled; • Volume of spilled sewage discharged to Waters of the State; • Track service (lower) lateral maintenance, separately from gravity mains, for mains, and lift stations; • Track progress on prioritized CIP projects for reducing risks of spills; • Maintain the staffing contact information annually in this SSMP to reflect staffing changes; and • Conduct and implement observations found in the 3-year audits.

GO SSMP Element 9.

The Plan must include an Adaptive Management section that addresses Plan implementation effectiveness and the steps for necessary Plan improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate Plan activities;
• Monitoring the implementation and measuring the effectiveness of each Plan Element; • Assessing the success of the preventive operation and maintenance activities; • Updating Plan procedures and activities, as appropriate, based on results of monitoring and performance evaluations; and
Identifying and illustrating spill trends, including spill frequency, locations and estimated volumes. 296
Element 9 Monitoring, Measurement and Program
June 2025 9-2 Sewer System Management Plan
City of West Sacramento

9.1.1 BASELINE PERFORMANCE
The historical, or baseline, performance is shown separately for gravity mains, lift stations, force mains, and public laterals. Overall, the performance of the system can be documented through the spill rate per 100 miles per year, as shown on Figures 9-1. The City maintained an averaged (mean) spill rate of 1.9 spills per 100 miles per year between 2007 and 2015 and 2.1 for the years 2015 to 2023 (Figure 9-1). As such, the rate has remained fairly stable.

Figure 9-1
Number of Spills (SSOs) per 100 Miles
The 2025 SSMP audit included in Appendix C includes much more monitoring and metrics of the program. The City will evaluate the performance of its wastewater collection system at least annually using the performance measures identified in this Element. The City will update the data and analysis at the time of the evaluation and will place the annual performance report in Appendix D of the SSMP.

The City may use other performance measures in its evaluation. The City will prioritize its actions and initiate changes to this SSMP, its operations and maintenance practices, and any related programs based on the results of the evaluation. This will be done as part of the annual self-audit.

9.2 Implementation
Implementation of this element consists of following those performance measures listed a bullets in Sub-element

9.1. 9.3 Resilience
Element 9 fosters resilience by requiring the City to monitor its progress using its own metrics. This will help to improve the program.

10 Internal Audits

10.1 Audits
The City will audit its implementation and compliance with the provisions of this SSMP every three years as required by the WDR. The audit will be conducted and completed no later than every three years following original adoption by the City Council. The audit will be conducted by a team consisting of City Staff selected from the Public Works Department. The audit team may include members from other departments of the City, outside agencies, or contractors. It is also recommended that an audit of the City’s Spill files occur to assure that that the files are complete, contain all required records as stated in the MRP and that the files contain no extraneous or conflicting documents that are not adequately reviewed and explanations provided be conduct.

The results of the audit, including the identification of any deficiencies and the steps taken or planned to correct deficiencies will be included in an Audit Report. Upon completion of the audit, the City will include a copy of the Final Audit Report in the updated SSMP and file the audit with the State Water Resources Control Board using the CIWQS Sanitary Sewer System Database. Modifications and changes to the SSMP will be identified and tracked in
Appendix D.

The audit may contain information about successes in implementing the most recent version of the SSMP, and identify revisions that are needed for a more effective program. Information collected can be used in preparing the audit. Tables and figures or charts can be used to summarize information about these indicators. An explanation of the SSMP development, and accomplishments in improving the sewer system, should be included in the audit, including:
• How the sewer system agency implemented SSMP elements since the last audit; • The effectiveness of implementing SSMP elements;
• A description of the additions and improvements made to the sanitary sewer collection system in the past reporting year; and
GO SSMP Element 10.

The Plan shall include internal audit procedures, appropriate to the size and performance of the system, for the Enrollee to comply with section 5.4 (Sewer System Management Plan Audits) of this General Order. 299

• A description of the additions and improvements planned for the upcoming reporting year with an estimated schedule for implementation.

10.2 SSMP Updates
The City will recertify its SSMP at least every six years from City Council adoption and approval or when substantial changes are made in the SSMP. The City will determine the need to update its SSMP more frequently based on the results of the audits and the performance of its wastewater collection system using information from the Monitoring and Measuring Program in Element IX. In the event that the City decides that an update is warranted, the process to complete the update will be identified, assigned to certain staff and include a schedule for completion. The City will complete the update and take the revisions to the City Council for discussion and approval.

Next Internal Audit is due Aug. 2 2028.

10.3Resilience
Element 10 requires the City to conduct audits. Audits build resiliency by ensuring compliance and indicating what can be improved. This will result in fewer spills, less escaped sewage, and faster cleanups. 300

11 Communication Program

11.1Communication During SSMO Development and Implementation The City maintains a website (www.cityofwestsacramento.org) to inform the public about City activities. The City’s website is an effective communication channel for providing alerts and news to the public. The website provides important announcements, public hearing notices, links to agendas and minutes for City Council meetings, and other key information for City residents. The City will publish the most up-to-date SSMP on the City website.

Other information provided upon request to interested parties includes: brochures and materials regarding collection system operations and maintenance and contact information and/or opportunities for input into the implementation process. The City will also have brochures and information on collection system programs at various department counters in the City as well as available on the City website.

GO SSMP Element 11.

The Plan must include procedures for the Enrollee to communicate with:
• The public for:
o Spills and discharges resulting in closures of public areas, or that enter a source of drinking water, and
o The development, implementation, and update of its Plan, including opportunities for public input to Plan implementation and updates.
• Owners/operators of systems that connect into the Enrollee’s system, including satellite systems, for:
o System operation, maintenance, and capital improvement-related activities. 301

11.2Communication with Regional San
Regional San developed and implemented a communications program with its four contributing agencies, including West Sacramento. Regional San holds meetings with representatives from contributing agencies on an as-needed basis to discuss common issues and provide support during the SSMP implementation process. This program is described in the SSMP for Sacramento Regional County Sanitation District, which is included at www.regionalsan.com.

Regional San and West Sacramento also have policies in place for spill coordination, which are documented in the operating agreement between Regional San and the City:

When an spill is reported, the agency receiving the notification will assign an Incident Responder. The Incident Responder will investigate the spill and take all appropriate steps to respond in accordance with that agency’s Spill Standard Operating Procedures. If it is known that the other agency is the responsible party, a transfer of the incident will be formally made.

SSO Response Plan
Section 1 Introduction

1.1 Introduction
On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Order No. 2006-0003- DWQ (Order). The Order requires all federal and state agencies, municipalities, counties, districts, and other public entities (Enrollees) that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California to comply with the Statewide General Waste Discharge Requirements (WDR). The WDR outlines requirements for Enrollees to ensure that a system-wide operation, maintenance, and management plan is in place to reduce sanitary sewer overflows (SSOs) within the state.

In September 2013, the Monitoring and Reporting Program (MRP), which is Attachment A to the Order, was amended. The revisions have been incorporated into the City’s SSO Response Plan.

Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age, construction material failures, lack of proper operation and maintenance, insufficient capacity and contractor-caused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures, and effective operation and maintenance of the sanitary sewer system.

1.2 Sewer System Management Plan
Under the WDR each Enrollee must develop and implement a Sewer System Management Plan (SSMP). The SSMP must include provisions to provide proper and efficient management, operation, and maintenance of the sanitary sewer systems. Additionally, the SSMP must contain a Sanitary Sewer Overflow Response Plan (SSORP) that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions.

Elements of the SSORP include: proper internal notification procedures, appropriate response to all overflows, procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities, procedures to ensure that appropriate staff and contractor personnel are aware of the SSORP and are appropriately trained. Procedures to address emergency operations such as traffic and crowd control and a program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from an SSO.

1.3 Purpose
The purpose of the SSORP is to satisfy the requirements of the WDR. The ultimate purpose of the SSORP is to provide procedures to effectively manage the response and the remediation of an SSO when it occurs in an effort to protect public health as well as the environment. 346

City of West Sacramento Page 15
SSO Response Plan
Section 5 Impact Mitigation

5.1 Standard Operating Procedures
When an SSO occurs, all feasible steps must be taken to prevent impacts including controlling or limiting the amount of wastewater to the storm drain system, terminating the discharge and recovering and properly disposing of as much of the SSO as possible including wash down water that is used. Standard Operating Procedures (SOPs) have been developed and implemented covering cleanup and remediation of SSOs. These SOPs are found in the Appendix section of this Plan.

5.2 Collection System Failures
In the event of a failure on a sewer main line, sewer forced main, pump station or any other portion of the sanitary sewer collection system, it may be necessary to notify upstream industrial dischargers of the situation and request that they reduce their sewer discharge. Additionally, some sanitary sewer pump stations are fed by other sanitary sewer pump stations within the system. Should this be the case, upstream pump stations will need to be turned off so repairs can be completed. Continuous monitoring of pump station wet well levels shall be conducted to ensure that the capacity is sufficient for the time the pump station is off. Large failures may require an extended amount of time for repair.

Bypass pumping (manhole to manhole) and/or mobile sewage collection may be necessary with prolonged repair. If necessary, City staff will coordinate with commercial septage haulers for assistance. See Appendix G for listing of septage haulers.

5.3 Discharges to Storm Drains or Surface Waters
If an SSO has entered or is entering a storm drain, steps should be taken to prevent further discharge from entering and isolate the impacted portion of the storm drain system to prevent the wastewater from reaching a waterway. It may be possible to isolate the SSO by switching storm water pumps off.

The contained wastewater can then be collected and discharged back into the sanitary sewer system.

Once an SSO reaches surface waters it might not be possible to contain and remove the wastewater.

Focus should be made on limiting the amount entering the surface waters, debris removal and sampling to determine the extent of the contamination.

Procedures for responding to SSO discharges to storm drains or surface waters can be found in Appendix B. The sampling SOP can be found in Appendix D. 357
Impact Mitigation
City of West Sacramento Page 16
SSO Response Plan

5.4 Traffic and Crowd Control
Traffic and crowd control measures vary based on the size of the SSO and its location. When appropriate, local police, fire department and other city personnel should be notified and requested to assist in traffic and crowd control.

5.5 Cleanup
SSO sites must be thoroughly cleaned after the SSO such that no identifiable residue remains, such as rags, sewage solids and other debris. Solids and debris must be collected and disposed of properly. Several actions must be taken to properly cleanup and mitigate potential effects, including but are not limited to:
• Application of absorbent material;
• Removal of contaminated soil and used absorbent;
• Flushing the SSO site with relatively clean water;
• Return of all wash-down water to the sanitary sewer.

5.6 Public Interaction
The public may be present during an SSO. Access to the affected area should be restricted to authorized personnel only. Efforts should be made to warn the public as to the dangers of coming into contact with raw sewage (see Section 4.3 Signage).

5.7 Media Notification
If necessary, when public health could be affected the City’s PIO will issue a news release related to the SSO.

5.8 Residential Claims
If an SSO in the City’s maintained system resulted in a flooded home or structure the City’s insurance carrier will be the lead on any claims.

Appendix C
SSO Flow Estimation Methods
Volume of the SSO can be determined using a variety of approaches. The following sections will discuss two methods that are often employed. The person preparing the estimate shall use the method most appropriate to the SSO in question. Every effort shall be made to make the best possible estimate of the volume.

Method 1 Measured Volume
This method can be used on small spills if it is not raining.

Step 1: Sketch the shape of the spill that is contained.

Step 2: Measure the length and width.

Step 3: Measure the depth in several locations.

Step 4: Convert all dimensions to feet.

Feet = inches/12
Step 5: Calculate the area using the following formulas.

Rectangle Area = Length x Width
Circle Area = Diameter x Diameter x 0.785
Triangle = Base x Height x 0.5
Step 6: Multiply the area times the depth to get the volume.

Volume ft3= Area x Depth
Step 7: Multiply the volume by 7.48 gallons/ft3to convert it to gallons.

Gallons = Volume x 7.48 gallons/ft3
Method 2 Duration and Flow Rate
Duration: The duration is the total elapsed time from when the SSO started until it stops.

Flow Rate: The rate at which the SSO is flowing. Usually expressed as gallons per second (GPS) or gallons per minute (GPM) or gallons per hour (GPH).

Open channel flow: Often overflows run into nearby dry ditches or street gutters.

Total volume, gallons, of flow can be quantified by measuring the cross-sectional area and speed of the flow. Measure a set distance paralleling the SSO flow route.

Measure, in inches, the midway width and depth of the flow over this distance. Then measure the time, in seconds, it takes a float to travel the set distance. Record total time of the SSO flow.
363
Appendix C
Calculate the total SSO volume of the following example:

Example: After measuring off a set distance of 20 feet, it was determined that the float took 20 seconds to travel this 20 feet. The width and depth at the midway point of the flow was 28 inches and 3 inches, respectfully. The total time of the SSO flow was 20 minutes. What is the total volume, gallons, of this SSO event? Total Volume (gal) = Velocity (ft/sec) x Area (ft2) x total time (seconds) x 7.48 gal/ ft3 = 20ft/20sec. x (28 x 3)/144) ft2 x (20min. x 60sec. /min.) x 7.48 gal/ ft3
= 1 x 0.58 x 1200 x 7.48 gal
= 5,220 gallons
Pump Stations: SCADA systems can provide flow or pump run time data for sewer and storm water pump stations. Pump curves may need to be obtained to determine flow rates. The flow rates can be used to determine flow volumes. Contact the city’s Treatment Plant Mechanics to obtain SCADA data.

SSO Flow Estimation Pictures (see next page): Provides pictures of sewage flowing from a manhole cover at a variety of flow rates. Observations by the responding utility maintenance crew are used to select the appropriate flow rate from the chart. 364

SSO Sampling Procedures Sampling for Coliform
(Total & e Coli), BOD and Ammonia
When sampling a SSO a minimum of three separate sample sets must be collected. One upstream of the discharge location, one at the discharge location and one downstream of the discharge location.

What you will need:

Personnel protective equipment including latex/nitrile gloves and eye protection.

Sub Surface Grab Sampler (used for sampling surface waters) *6 – 100 mL sterile plastic containers for coliform analysis. 3 for samples with 3 extra. *6 -1 Liter Poly containers for BOD. 3 for samples with 3 extra. *6 – 500 mL Poly containers preserved with H2SO4 for Ammonia analysis. 3 for samples with 3 extra.
3 – 1 Liter soda lime bottles
3 – 1 Liter glass jars
3 – funnels
Cooler with ice packs
Chain of Custody
*Ensure that there are adequate amount of sample equipment if known more than three sample locations.

Procedure:

1. Put on all required protective equipment including latex/nitrile gloves and eye protection.

2. Use the 100 mL sterile container for coliform, 1-liter poly container for BOD and 500mL poly container for ammonia.
• Three sets of samples are collected for each incident: up stream, entry point, downstream.
• One set is one 1-liter bottle for BOD, one 100 mL container for coliform, and one 500 mL bottle for Ammonia (preservation with H2SO4 required).. • All samples are grabs and are collected at 6” below the surface. Samples shall be placed in coolers on ice packs during transport to the lab.

3. Once the lid is opened, the inside surface of the bottle or lid should not be touched.

Care should be taken with the sample containers that contain a preservative to keep the preservation in the container.

4. Get into position to collect the sample. Try to collect the sample in the middle of the flow.

5. Once in position,

6. Avoid sampling debris or scum layer from the surface. To avoid this, the surface may need to be agitated before sampling.

7. Use a glass jar for spills and flowing material and use the Sub Surface Grab Sampler when sampling surface waters.

8. Rinse the sample collection container (glass jar, soda lime bottles).

9. Collect sample in sample collection container.

10. Transfer sample from sample collection container to individual sample bottle(s). Leave approximately one inch of head space in individual sample bottles. Do not overfill.

11. Immediately, place all samples on ice and cool to 4⁰C.

12. Complete Chain of Custody form and take samples to contracted environmental laboratory.

• An evaluation of the previous audit to ensure deficiencies have been rectified. • Identified compliance gaps/deficiencies in adhering to the requirements of the reissued General Order for all elements and sub-elements, including resilience. • Identified implementation gaps/deficiencies in performing as described in the current SSMP. • Identified effectiveness gaps/deficiencies for all elements (and in some cases the subelements) using key performance indicators in preventing spills and discharges to waters of the State.
• Specific short and long-term corrective actions or enhancements needed to rectify each gap/deficiency and a schedule for each action.

1.0 Introduction
The reissued General Order includes changes and additional requirements for a City to comply with federal and state prohibitions of discharge of sewage to waters of the State; comply with specifications, notification, monitoring, reporting and recordkeeping requirements; proactively operate and maintain resilient sanitary sewer systems to prevent spills, eliminate discharges of sewage to waters of the State through effective implementation of an SSMP; monitor, track, and analyze spills for ongoing systemspecific performance improvements; and report noncompliance with the reissued General Order per reporting requirements.

The City’s SSMP was last updated in June 2018 and the Sanitary Sewer Overflow Response Plan was updated in January 2015.

2.0 Key Regulatory Drivers
While considering that the City’s collection system is relatively small with average complexities, we recommend that the City focus their regulatory compliance efforts on 1) meeting the requirements of the General Order, and 2) avoiding enforcement actions – both of which are highlighted in the following sections.

2.1 SSMP Audit Requirements
The key requirements for SSMP Audits are described in Section 5.4 of the General Order as:

5.4. Sewer System Management Plan Audits
The Enrollee shall conduct an internal audit of its Sewer System Management Plan, and implementation of its Plan, at a minimum frequency of once every three years. The audit must be conducted for the period after the end of the Enrollee’s last required audit period.

Within six months after the end of the required 3-year audit period, the Legally Responsible Official shall submit an audit report into the online CIWQS Sanitary Sewer System Database per the requirements in section 3.10 (Sewer System Management Plan Audit Reporting Requirements) of Attachment E1 of this General Order.

Audit reports submitted to the CIWQS Sanitary Sewer System Database will be viewable only to Water Boards staff.

The internal audit shall be appropriately scaled to the size of the system(s) and the number of spills. The Enrollee’s sewer system operators must be involved in completing the audit. At minimum, the audit must:
• Evaluate the implementation and effectiveness of the Enrollee’s Sewer System Management Plan in preventing spills;
• Evaluate the Enrollee’s compliance with this General Order; • Identify Sewer System Management Plan deficiencies in addressing ongoing spills and discharges to waters of the State; and
• Identify necessary modifications to the Sewer System Management Plan to correct deficiencies.

The Enrollee shall submit a complete audit report that includes:
• Audit findings and recommended corrective actions;
• A statement that sewer system operators’ input on the audit findings has been considered; and
• A proposed schedule for the Enrollee to address the identified deficiencies.

SSMP Audit reporting and recordkeeping requirements are described in General Order Attachment E1, Section 3.10., which states:

3.10. Sewer System Management Plan Audit Reporting Requirements The Enrollee shall submit its Sewer System Management Plan Audit and other pertinent audit information, in accordance with section 5.4 (Sewer System Management Plan Audits) 374
January 24, 2025 | Page 3
City of West Sacramento - Sewer System Management Plan Audit of this General Order, to the online CIWQS Sanitary Sewer System Database by six (6) months after the end of the 3-year audit period.

If a Sewer System Management Plan Audit is not conducted as required: the Enrollee shall:
• Update the online CIWQS Sanitary Sewer System Database and select the justification for not conducting the Audit; and
• Notify its corresponding Regional Water Board (see Attachment F (Regional Water Quality Control Board Contact Information)) of the justification for the lapsed requirements.

The Enrollee’s reporting of a justification for not conducting a timely Audit does not justify non-compliance with this General Order. The Enrollee shall:
• Submit the late Audit as required in this General Order; and • Comply with subsequent Audit requirements and due dates corresponding with the original audit cycle.

The State Water Board transitioned SSMP Update and Audit due dates to align with the changes in the Reissued General Order, and lists them on the State Water Board website here:
https://www.waterboards.ca.gov/water_issues/programs/sso/lookup/. The City’s due dates are shown in Figure 2-1.

2.3 Enforcement Considerations
The City’s Legally Responsible Officials (LROs), managers, and Board of Directors should review and be aware of potential liabilities for noncompliance with the General Order. An excellent practice is to review enforcement language outlined in Specifications 5.17 and 5.18 (page 27) and Provisions 6 (pages 27-31) of the General Order. In addition, the City should also:

1. Keep abreast of the latest Water Board enforcement penalty actions in Region 5 (see CIWQS Administrative Civil Liability ACL Report) and review example enforcements to improve City understanding about the enforcement process and potential ramifications for noncompliance.

Here is one example of a Region 5: Central Valley Regional Water Board Enforcement.

2. Review the most current version of the Water Board Enforcement Policy to understand the specific factors considered by State/Regional Water Boards in assessing civil liabilities with formal enforcement Orders. The most recent Policy was changed in 2017 (potentially affecting the example above). As of June 2024, the State Water Board has proposed additional changes to the Policy. Visit the State Water Board’s Office of Enforcement Water Quality Enforcement Policy Amendments for the latest Policy.

3. Review the list of common violations summarized in Attachment B of this letter. 378

City of West Sacramento - Sewer System Management Plan Audit

3.0 SSMP Audit Methodology
The process used to audit the City’s 2018 SSMP is described below and aligns with the recommendations of the Bay Area Clean Water Agencies Guide for Developing and Updating Sewer System Management Plans.

1. Collect available background information and system performance data from the City.

2. Conduct a desktop review of information provided by the City and publicly available benchmark data.

3. Conduct staff interviews at all levels of the organization - including operations and maintenance staff.

4. Evaluate the existing SSMP for compliance, implementation and effectiveness while addressing system resilience.

5. Develop a draft SSMP Audit Report summarizing findings and a corrective action plan.

6. Review the draft SSMP Audit Report with City staff (including operations and maintenance staff) and document an agreed upon schedule.

7. Finalize the SSMP Audit Report and submit it to the City for certification/upload.

The General Order requires that the audit evaluate the existing SSMP for compliance, implementation and effectiveness while addressing system resilience. These terms are defined as:
• Compliance is the act of meeting regulations. Compliance is the most fundamental aspect of the SSMP as all the requirements in the individual elements must be incorporated and addressed.

Attachment D of the General Order specifies “The City’s development, update, and implementation of an SSMP addressing the requirements of this Attachment is an enforceable component of this General Order.”
• Implementation is the actions or steps taken to accomplish tasks, goals, and objectives. There needs to be a plan and schedule to carry out these actions. To implement a plan, a goal, level of effort, resources, and timeline need to be determined.
• Effectiveness is the degree to which something is successful in producing a desired result. There must be a procedure or method to measure effectiveness so the degree to which something is effective can be determined. A requirement of an internal audit (Element 10 of the SSMP) is to measure the effectiveness of each SSMP element.
• Resilience is the ability to recover from or adjust to adversity or change and grow from disruptions and includes recovering from system failures. Resilience can be built through planning and preparation for, mitigation of, and adaptation to changing conditions.

Key Performance Indicators (KPIs) are used to evaluate the effectiveness of the program. A KPI is a measurable target that indicates how plans and processes are working in terms of obtaining desired results. KPIs provide focus for strategic and operational improvements, create an analytical basis for decision making, and help place attention on what matters most. 379
