Foster City, CA 94404

Dear Mr. Schoening,

We are pleased to present the new 2025 Sewer System Management Plan (SSMP) Update developed in partnership with the management of Foster City and Estero Municipal Improvement District (EMID). The 2025 Update meets and exceeds compliance with the WDR (State Water Board, Water Quality Order No. 2022 -0103-DWQ, Attachment D -10 and Speciﬁcations 5.4). The 2025 SSMP has been completely revised to harmonize with industry standard guidelines and incorporates the City and EMID’s latest SSMP Audit ﬁndings.

The 2025 SSMP is a declaration of what the City and EMID are doing to demonstrate full compliance with the WDR. Attachment A of the WDR (page A-4), states “A sewer system management plan is a living document an Enrollee develops and implements to eﬀectively manage its sanitary sewer system(s) in accordance with this General Order.” We suggest that the City and EMID review the SSMP on a regular basis, and as required by the WDR, continuously document changes to the SSMP in a change log attached to the Plan.

We look forward to assisting the City and EMID wherever necessary to fully implement the 2025 SSMP Update.

Sincerely,

James Fischer, P.E.

OVERVIEW
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for Foster City and Estero MID use only. Page 1 of 57 Introduction
This Sewer System Management Plan (SSMP) or “Plan” has been prepared for the Estero Municipal Improvement District/City of Foster City (jointly referred to as “City”) with technical assistance from Fischer Compliance LLC with the goal of meeting and exceeding compliance with the State Water Resources Control Board 2022 General Waste Discharge Requirements, Order No. WQ 2022-0103-DWQ for Sanitary Sewer Systems (referred to throughout this document as the WDR ). The City provided all details, information and institutional insights for preparation of the SSMP. The document has been developed to meet the size, scale, and complexity of the City, serving as a “living document” used as a tool for managing and operating the City’s sanitary sewer collection system. Additionally, the latest 2024 Sewer System Management Plan Guidance Manual published by the Bay Area Clean Water Agencies (BACWA) was utilized as a model for development of the document to harmonize formatting/content and incorporate recommended suggested guidance wherever possible.

Although the District is in the process of achieving full compliance with the WDR, the summary of spill metrics (below) shows that the City consistently performs better than both the statewide and regional spill rate indices and net spill volumes for all categories of spills from its sanitary sewer collection system.

This SSMP, including Appendix 10, provides a list of items which the City intends to complete such that it will comply with the WDR.

Figure 1 provides key spill metrics, including data comparing the City’s spill record with state and regional system data for the ﬁve-year period of May 2020 through May 2025.

GOAL AND INTRODUCTION

1.3. Sewer System Asset Overview

WDR REQUIREMENTS
Att. D-1.3 (pg. D-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 percentage 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.”

COMPLIANCE
The Estero Municipal Improvement District (EMID) maintains the sanitary sewer collection and pumping system within Foster City. EMID is governed by the Foster City’s City Council /EMID Board of Directors and Foster City provides the staﬀ for EMID. Because CIWQS shows Foster City as the Enrollee under the WDR, this SSMP considers both Foster City and EMID to be one entity and refers to both jointly as “City”.

Foster City is in San Mateo County. The City’s wastewater collection system serves a population of 37,200 people through 13,937 service connections. Due to the City’s ﬂat topography, the existing collection system is designed as a network of lift stations that collect and transport sewage from the outer basins to the inner basins until the wastewater ultimately reaches pump station 59, which is the ﬁ nal and largest capacity station within the City’s collection system. From pump station 59, w astewater is transported to the San Mateo Regional Wastewater Treatment Plant for treatment and disposal. The WWTP is jointly owned by the City of San Mateo and Foster City and is operated by the City of San Mateo. Figure 3, below, shows the area served by the wastewater collection system. The system serves all of Foster City.

The City’s sanitary sewer system includes 63 miles of gravity sewers, 3 miles of force mains, 48 lift stations and one pump station. The 48 lift stations include ﬁve medium size lift stations (125,000 to 500,000 gpd) and 43 small lift stations (less than 125,000 gpd). The largest pump station has a capacity of 9 million gallon per day (mgd) and is in the District’s Corporation Yard. Th is pump station is the last stop before almost 3 mgd of the wastewater is pumped to the San Mateo WWTP. The Corporation Yard pump station and 14 of the lift stations have dedicated standby generators. In addition, the City has two newer and two older portable generators with “quick connect” features to provide power to the other lift stations.

Most of the collection system was installed between 1960 and 1980. Pipe sizes range from 4 to 21 inches in diameter with 88% at 12 inches or less. G ravity sewers are constructed of clay (65%), polyvinylchloride

GOAL AND INTRODUCTION

The City is not responsible for maintenance or repair of sewer service laterals. Each property owner is fully responsible maintenance of their private sewer lateral to the main in the street.

The City does not have any structures that divert stormwater to the sewer system.

The City recently acquired a Computerized Maintenance Management System ( CMMS) to manage its collection system and anticipates deployment by the end of 2026. Currently , the City use s Excel spreadsheets to manage its data. The City keeps its maps up to date.

The percentage of residential, commercial, and industrial service connections is shown in Table 2, below.

The City is unique in that it is a master planned community, constructed by ﬁlling in marshland in the San Francisco Bay. The area has a high groundwater table, potentially leading to inﬁltration of the sewer system during storms or high tides. In addition, the City was constructed around a 5-mile-long lagoon. Two force mains go underneath the lagoon while one force main goes over the lagoon on Shell Blvd bridge.

GOAL AND INTRODUCTION

WDR REQUIREMENTS
Speciﬁcation. 5.2 (pg. 18)
“To facilitate adequate local funding and management of its sanitary sewer system(s), the Enrollee shall develop and implement an updated Sewer System Management Plan. The scale and complexity of the Sewer System Management Plan, and speciﬁc elements of the Plan, must match the size, scale, and complexity of the Enrollee’s sanitary sewer system(s). The Sewer System Management Plan must address, at minimum, the required Plan elements in Attachment D (Sewer System Management Plan – Required Elements) of this Genera l Order. To be eﬀective, the Sewer System Management Plan must include procedures for the management, operation, and maintenance of the sanitary sewer system(s).

The procedures must: (1) incorporate the prioritization of system repairs and maintenance to proactively prevent spills, and (2) address the implementation of current standard industry practices through available equipment, technologies, and strategies.”

COMPLIANCE
The City’s current Sewer System Management Plan (SSMP) has been updated to meet the requirements of Order WQ 2022 -0103-DWQ and addresses the required Elements. The SSMP addresses management, operations and maintenance procedures speciﬁc to the City’s collection system. The City maintains a proactive O&M program to operate its system and identify defects, which are then prioritized for repair, replacement, rehabilitation, or placed on modiﬁed maintenance schedules. (See Elements 4 and 8 and Speciﬁcations 5.19 of this SSMP for more detail.)
The City keeps up with current industry standards, technology and best practices by reviewing industry periodicals, networking , attending training classes, attending CWEA conferences and workshops , and talking to v endors about new products . The City continuously evaluates emerging practices, equipment and technologies for possible implementation to enhance sewer operations.

GOAL AND INTRODUCTION

WDR REQUIREMENTS
Speciﬁcation. 5.7 (pg. 22)
“The Enrollee shall comply with the following requirements:
• Establish and maintain a means to manage all necessary revenues and expenditures related to the sanitary sewer system; and
• Allocate the necessary resources to its sewer system management program for:
• Compliance with this General Order,
• Full implementation of its updated Sewer System Management Plan, • System operation, maintenance, and repair, and
• spill responses.”

COMPLIANCE
The Estero Municipal Improvement District (EMID) is an independent special district of Foster City. Foster City provides the staﬀ for all management and operations of the EMID assets for sewer collection . All services provided to support EMID are billed to EMID and are funded by an enterprise fund managed by the City. The City regularly (annually) conducts evaluations of its sewer program rate and charges to assure full funding of the program, including treatment costs for all dischargers in the service area. The EMID service area is coterminous with the City of Foster City, and all sewage is discharged into assets owned and managed by EMID.

There are two main sources of revenue:
• The Wastewater Enterprise Fund is funded by wastewater rates charged to the City’s customers. This money can be used on operation and maintenance, capital improvement, professional services, and the City’s share of the cost to operate and maintain the San Mateo Regional Water Quality Control Facility.
• “Developer fees” (connection fees) are charged to developers of new projects that will tie into the collection system. This money is used to pay for the project ’s fair share of the existing wastewater treatment and collection infrastructure capacity.

GOAL AND INTRODUCTION

WDR REQUIREMENTS
Provisions 6.1 (pg. 27)
“The following enforcement provisions are based on existing federal and state regulations, laws and policies, including the federal Clean Water Act, the state Water Code and the State Water Board Enforcement Policy.”

COMPLIANCE
The City is aware of the consequences for noncompliance including associated penalties for violations. The City maintains a proactive stance with full implementation of its SSMP.

Noncompliance with requirements of this General Order or discharging sewage without enrolling in this General Order constitutes a violation of the Water Code and a potential violation of the Clean Water Act and is grounds for an enforcement action by the State Water Board or the applicable Regional Water Board.

2.3. Chain of Communication for Reporting Spills
The City may learn of a spill from the public, receipt of an alarm, or observation by City staﬀ.

Public Observation. Public observation is the most common way that the City is notiﬁed of blockages and spills. Contact information for reporting sewer spills and backups is on the City’s website on the Public Works page. The website states “ In the event of a sewer overﬂow or backup during working hours (Monday through Thursday, 7:30 am - 4:30 pm; Friday, 7:30 am - 3:30 pm), please notify the Wastewater Division IMMEDIATELY by calling (650) 286 -8140. After working hours, please contact Police Dispatch at (650) 286-3345. Please do not email or report electronically.” When a report of a sewer spill or backup is made, City staﬀ receives the call, takes the information from the caller, ﬁlls out the ﬁrst section of the Sewer Report Form, and communicates it to the Wastewater Lead Worker who responds to the site and/or dispatches a ﬁeld crew.

The Public Works (PW) Field Crew determines from the information provided if the PW Maintenance Superintendent and/or PW Maintenance Manager need to be notiﬁed and immediately responds to the site.

After hours, the Police Dispatcher receives the call, takes the information from the caller, and communicates it to the PW Standby Person.

Receipt of an alarm. The City’s large ( 9 mgd) p ump station, four medium sized lift stations and remaining 44 smaller lift stations are monitored using SCADA. Alarm conditions are monitored by the City’s administrative staﬀ during normal working hours and Police Dispatch after hours. If an alarm is received, they notify appropriate City staﬀ of the lift station alarms.

City staﬀ observation: City staﬀ conduct periodic inspections of the sewer system facilities as part of their routine activities. Any problems noted with the sewer system facilities are reported to appropriate City staﬀ who, in turn, respond to emergency situations.

Staﬀ respond to the spill using the procedure in the Spill Emergency Response Plan (Section 6) and complete relevant forms. The information is then submitted to the Maintenance Superintendent for review and veriﬁcation of data , including reviewing spill volume ca lculation, prior to submittal to CIWQS.

3. Legal Authority

WDR REQUIREMENTS
Att. D-3 (pg. D-4)
“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.”

COMPLIANCE
The above items are addressed in order below. Regulations pertaining to sewer service are found in Title 8 of the Estero Municipal Improvement District Code, which is a component of the Foster City Municipal Code.

Authority to prevent illicit discharges into the wastewater collection system.

Section 8.37.110 prohibits general discharges of wastewater that may interfere with the POTW or damage the conveyance system. Section 8.37.120 prohibits speciﬁc types of discharges such as explosives, corrosives, solids (including fats, oils, grease), debris, and unpolluted water. Section 8.37.150 prohibits the discharge of groundwater except under certain conditions and with a permit.

Pre-planned collaboration and coordination with storm drain agencies.

In addition to owning and operating the sanitary sewer system, Foster City also owns and operates all storm drains within the City limits. Therefore, City staﬀ can coordinate internally to respond to spills, ensure access to storm drains, and prevent cross connections. There are no County -owned storm drains within the City.

Require that sewer system components and connections be properly designed and constructed.

Section 8.32.010 states that “Design and construction of public sewers, building sewers and sewer laterals shall be in accordance with the standards established by the director of public works.” Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the Enrollee.

The City is not responsible for any sewer laterals. Section 8.32.100 states that “… sewer laterals shall be maintained by the owner of the property served.”
Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures.

LEGAL AUTHORITY
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for Foster City and Estero MID use only. Page 23 of 57 Section 8.04.130 states that a customer’s service may be disconnected for failure to comply with the City’s ordinances. S ections 8.12.230 through 8.12.280 provide escalating enforcement options for failure to comply the City’s ordinances. Section s 8.37.440 through 8.37.470 also describe escalating enforcement options.

Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

Foster City is a master planned community and is completely built out. Therefore, there is no need for the Municipal Code to contain a reference for future easement accessibility agreements. There are a few existing easement agreements which are maintained by the City’s Engineering Department.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring eﬀectiveness of this Element:
• Are the City ordinances and standards adequate for fulﬁlling the SSMP legal requirements? • Does the City have a process in place for periodic review and evaluation of ordinances? • Have there been instances when the code or ordinance did not address a need or circumstance?

4. Operation and Maintenance Program

WDR REQUIREMENTS
Att. D-4 (pg. D-4)
“The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.”

4.1. Updated Map of Sewer System

WDR REQUIREMENTS
Att. D-4.1 (pg. D-4)
“An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staﬀ access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries.”

COMPLIANCE
The City maintains paper maps of its system, as well as computerized maps (ArcGIS) of all mainlines, manholes, and other facilities within the City. The GIS database stores data and enables staﬀ to retrieve information such as pipe type and diameter, the approximate manhole and cleanout locations, the location of drop manholes, pumping facilities, and the length of pipe between manholes.

Field staﬀ have access to the GIS database through their phones or tablets. I f ﬁeld staﬀ ﬁnd an error in a map, they will redline the map and refer the error to management. After internal review and veriﬁcation, management will send the information to the City’s IT Department to make the correction. If a map needs to be changed due to development, the Engineering Department will provide the information to the IT Department.

High priority corrections are completed within 30 days. High priority corrections refer to mapping information that could cause the ﬁeld crews to act in a manner that could cause a spill. Low priority corrections are completed once a year.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring eﬀectiveness of this Element:
• Were all map updates completed in a timely manner?
• Are all staﬀ trained in the procedure for providing map update information? • Are newly installed sewer assets incorporated into the system maps? • Are there terrain features or assets that should be incorporated in future map updates (e.g. exposed pipe, siphons, ARVs, surface water, etc.)

4.2. Preventive Operation and Maintenance Activities

WDR REQUIREMENTS
Att. D-4.2 (pgs. D-4/D-5)
”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.”

COMPLIANCE
The City currently uses Excel spreadsheets to program and track all required inspection and maintenance activities within the collection system. However, the City intends to transition to the Cartegraph CMMS software by 2026. Use of this software will allow the District to make informed decisions regarding its assets and infrastructure by using the data collected from ﬁeld work orders and documented inspections.

Sewer maintenance is currently scheduled using paperwork orders. The work orders cover preventive maintenance program and annual routine cleaning, based on the City’s 48 sewer basins. Completed gravity sewer maintenance is recorded using Excel spread sheets. When problems are found, they are listed on a white board.

City staﬀ clean 85-100% of the gravity system each year, working from the top lines to the bottom lines.

Staﬀ log their work into Excel each day. Operators inspect manholes as they clean and if something unusual is noted, will send a crew out. Most pipe repairs are completed in-house by City staﬀ. Manhole inspections are not currently documented but will be in the future using a form similar to that in Appendix 4.1.

When the City transitions to Cartegraph, the software will issue preventative maintenance, hot spot, and line repair work orders automatically.

The City has not had a CCTV program since the COVID pandemic; however, the City plans to hire a contractor by the end of 2025 and to resume the CCTV program in 2026. It is anticipated that work orders for CCTV inspections will be generated by Cartegraph.

Lift stations are inspected monthly, with results noted on logs maintained at each lift station and on work order request logged into GIS.

The City does not need to implement a root control program due to the high groundwater table.

Speciﬁcation. 5.19 (pg. 27)
“To prevent discharges to the environment, the Enrollee shall maintain in good working order, and operate as designed, any facility or treatment and control system designed to contain sewage and convey it to a treatment plant.”

COMPLIANCE
The City’s sewer system O&M program include:
• Proactive, preventive, and corrective maintenance of gravity sewers; • Rehabilitation and replacement of collection system facilities that are in poor condition; • Periodic inspection and preventive maintenance for lift station and force main facilities; and • Resumption of a CCTV program to determine the condition of the gravity sewers.

Gravity Sewers
The City cleans 85-100% of its sewer system every year, and it preventively cleans sewers with a history of problems (hot spots) every month. One collection system cleaning crew is assigned to these activities. The District’s standard operating procedure for collection system cleaning is similar to that found in Appendix

4.4. Gravity sewer maintenance is currently scheduled using paper work orders. The work orders cover preventive maintenance program and annual routine cleaning, based on the City’s 48 sewer basins.

Completed gravity sewer maintenance is recorded using Excel spread sheets . The City has established monthly and annual goals for production. Actual production is tracked, and corrective actions are implemented when production falls behind the goals. The City has a Hot Spots program, with lines cleaned on a weekly, monthly, and six-month schedule. The Hot Spots list is available upon request.

Prior to the Covid pandemic, the City used CCTV to determine the cause of its gravity sewer blockages and spills. Post COVID, the City lost staﬃng and expertise; therefore, the City intends to hire a CCTV contractor and resume CCTV inspections in 2026.

The City completes emergency repairs and non -emergency repairs using its ﬁeld crews . Repairs are identiﬁed by the sewer cleaning crew and repairs are completed in priority order.

The Collection System staﬀ maintains a list of known structural problems for use in providing input to Public Works Engineering on the Capital Improvement Program.

Manholes
Previously, the City’s CCTV crew inspected manholes. The City intends to contract out the CCTV program in 2026 and the CCTV crew will once again do the inspecting. Until the contractor is hired , the sewer cleaning crew visually inspects the manhole. If a problem is found, a paper work order form is completed and given to the Maintenance Superintendent for follow-up.

Lift Stations
Lift stations are inspected monthly, during the ﬁrst two weeks of each calendar month. Pump current draw is measured during the operational inspection and is used as a diagnostic tool to identify pump operating problems. Facility or equipment problems observed during the operational inspecti ons are noted on logs

DESIGN AND PERFORMANCE PROVISIONS

Page 33 of 57 maintained at the lift stations and on work order reports for follow -up action. Observed facility or equipment problems are also recorded on the whiteboard in the maintenance shop. All observations are transcribed onto the Lift Station Task spreadsheet. Th e completed corrective maintenance activities are also noted on the spreadsheet.

Preventive maintenance activities are completed during the second half of each month. Checklists are used to ensure that all required preventive maintenance tasks are completed.

Emergency generators are exercised monthly.

The results of the operational inspections, preventive maintenance tasks, and any corrective maintenance are recorded on paper work order forms. The completed work orders are recorded by asset in the District’s GIS system. The GIS system maintains a history of completed maintenance by asset.

The City formally inspects the condition of its lift stations annually. The inspection process is used to identify major maintenance and rehabilitation needs. The facility inspection is completed by a team that includes collection system ﬁeld staﬀ and other City employees as appropriate to the size and complexity of the facility and uses a checklist similar to that found in Appendix 4.5. The completed inspection checklists are reviewed by the Superintendent to determine whether repairs, major maintenance, or rehabilitation/replacement are warranted. Repairs and major maintenance are completed by City staﬀ.

Specialty repairs, maintenance, or rehabilitation/replacement are completed by contract.

Force Mains
Force main right-of-ways are inspected yearly to identify leakage and potential incursions associated with nearby construction. Air relief valves are inspected and maintained annually. The City is a member of Underground Service Alert and marks the location of its force mains to prevent damage by others during underground construction.

Non-Routine Maintenance
Non-routine maintenance activities include investigation and response to any complaints regarding a manhole overﬂow, missing or shifted manhole covers, manhole covers that are excessively noisy, residential plumbing troubles, pump station malfunction, une xpected sewer odor, etc. Sewer complaints are investigated, and appropriate actions are taken to resolve the source of the problem.

7. Sewer Pipe Blockage Program

WDR REQUIREMENTS
Attachment D-7 (pg. D-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.”

COMPLIANCE
The City’s FOG Control Program is provided under contract by the City of San Mateo. San Mateo’s FOG Control Program is described in detail in San Mateo's 2021 SSMP. San Mateo ’s Environmental Services Division, Source Control Section administers the FOG source control program while Building Departments of both San Mateo and Foster City issue permits for installation of grease control devices in conformance to requirements of Uniform Plumbing Code.

Foster City will ask San Mateo to provide quarterly updates regarding the work completed under the FOG Control Program.

The WDR’s requirements above are addressed below:

Public Outreach. The City of San Mateo conducts public outreach on behalf of the City of Foster City. San Mateo’s Environmental Compliance Inspectors distribute outreach materials , if necessary , during each commercial FSE inspection; they encourage managers of food service facilities to use the information to train employees upon hire and at least annually thereafter. San Mateo inspectors typically distribute a San Mateo-produced brochure titled Required Best Management Practices for Food Service Facilities that contains information on BMPs for the FOG and Stormwater programs. On the backside is Municipal Code Applicable to Food Service Establishments for reference. The brochure is provided in English, Spanish, and Chinese.

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for Foster City and Estero MID use only. Page 39 of 57 San Mateo inspectors also distribute a one -page handout provided by the San Mateo Countywide Water Pollution Prevention Program (SMCWPPP) titled Best Management Practices for Food Service Facilities. This is available in English, Spanish and Chinese.

A laminated poster for proper grease disposal titled No Grease Down the Drain – Keep Drains Flowing is provided during initial inspections for posting in the dishwash area of the kitchen. The poster is available in English, Spanish, Chinese, Korean and Vietnamese.

Residential outreach materials are on display at San Mateo City Hall and are distributed at the San Mateo Services Academy and other venues. Public service announcements may be published prior to major holidays to remind San Mateo residents of prudent food waste handling practices. A FOG BMP poster and the WEF “Fat Free Sewers” brochure is mailed to apartment complexes as needed, and after ﬁnding a FOG buildup in the sewer at or immediately downstream of an apartment connection. If necessary, the FOG brochure is distributed to all homes upstream of a recurring blockage.

Foster City occasionally attends community events and has door hangars and ﬂiers available to educate the community and local businesses on how to properly maintain their private sewer laterals. The City intends to add FOG control information to its website.

Disposal. FOG which is generated by FSEs is collected in grease interceptors or grease traps which are maintained by the FSEs. The accumulated FOG is pumped out by licensed haulers hired by the FSEs and taken to the haulers’ own facilities. The City’s sewer maintenance crew also removes FOG in the collection system during their routine maintenance activities. This grease is disposed of in drying beds at the City’s Corporation Yard and then taken to the Recology landﬁll, on an as-needed basis.

Legal authority to prohibit discharges. The Estero Municipal Improvement District Code, a component of the Foster City Municipal Code, regulates discharges to the sewer system. Section 8.37.120(E) prohibits the discharge of solids, including FOG, which could obstruct ﬂow within the sewer. Section 8.37.120(H) prohibits the discharge of oil and grease that exceeds speciﬁc concentrations.

Requirement to install grease interceptors, design standards, etc . Section 8.36.040 of the Foster City Municipal Code states that “Grease, oil and sand interceptors shall be provided in accordance to the FOG (fats, oil, and grease) control program and/or when in the opinion of the public works department are necessary…” Section 8.36.050 states that grease interceptors shall be maintained by the owner and shall be “in continuously eﬃcient operation.” Section 8.37.100 states that FSEs shall have a pretreatment system for grease removal and provides design criteria. S ection 8.37.160 reiterates the need for FSEs to install a grease removal system, provides sizing criteria, and states that if there is a grease buildup in the sewer, then additional grease control measures will be required. Section 8.37.340 states that records shall be kept for at least three years.

Authority to inspect and enforce. Section 8.37.350 of the Foster City Municipal Code describes the authority to inspect and monitor, including that an authorized City representative may “conduct all inspection, surveillance and monitoring procedures necessary to assure compliance with these rules and regulations.” FOG-related problem areas. The City has limited FSEs in its collection system. If staﬀ ﬁnd more grease than expected as they clean a line, they will report the location to San Mateo. San Mateo maintains the list of FSEs within Foster City.

Source control measures. San Mateo’s FOG Control Program, which is also implemented in Foster City, emphasizes six BMPs that should be followed by FSEs and other FOG generators within the service area.

These BMPs are summarized as follows:
• Employee Training and Awareness: This BMP recommends that all employees and FOG -producing establishments be adequately trained in activities to reduce FOG disposal into the sanitary sewer system.

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for Foster City and Estero MID use only. Page 40 of 57 • Garbage Grinder Elimination/Limitation: This BMP recommends that FOG generators eliminate garbage grinders or limit their use to the greatest extent possible, thereby reducing the amount of food particles that enter the sanitary sewer system with the potential to clog the system. Additionally, the use of drain screens is recommended by this BMP to capture food and other particles in order to prevent them from being discharged into the sanitary sewer system. These screens should be cleaned frequently and emptied into the trash.
• Spill Cleanup: This BMP emphasizes the use of dry -cleaning methods for cleaning up spills. If dry methods are insuﬃcient, water use and discharge to the sanitary sewer should be limited as much as possible.
• Equipment Cleaning and Maintenance: This BMP recommends that FOG generators limit the discharge of FOG to the sanitary sewer system to the greatest extent possible in the regular cleaning and maintenance of equipment.
• Grease Handling and Disposal: This BMP requires that oils, grease or other oily liquids (such as salad dressing) should not be discharged in large quantities to the sanitary sewer system. These materials should be recycled, if possible.
• Grease Removal Devices: This BMP requires that FOG generators install and maintain grease removal devices.

Because not all FOG problems are caused by food service facilities, residential and private dwelling customers are also urged to adopt the aforementioned BMPs, as applicable.

WDR REQUIREMENTS
Attachment D-8 (pg. D-)
“The Plan must include procedures and activities for:
• Routine evaluation and assessment of system conditions; • Capacity assessment and design criteria;
• Prioritization of corrective actions; and
• A capital improvement plan.”

8.1. System Evaluation and Condition Assessment

WDR REQUIREMENTS
Attachment D-8.1 (pgs. D-7/D-8)
“The Plan must include procedures to:
• Evaluate the sanitary sewer system assets utilizing the best practices and technologies available; • Identify and justify the amount (percentage) of its system for its condition to be assessed each year;
• Prioritize the condition assessment of system areas that:
• Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deﬁciencies;
• Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas;
• Are within the vicinity of a receiving water with a bacterial -related impairment on the most current Clean Water Act section 303(d) List.
• Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection method;

• Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; ﬂooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildﬁres; and increased power disruptions.”

COMPLIANCE
The above requirements are addressed below:

System Evaluation: The City assesses its system as it cleans the pipelines yearly and inspects its lift stations monthly. The City previously conducted CCTV inspections but has not done so since COVID. The City intends to hire a contractor and to resume CCTV inspections in 2026.

Justify amount of system assessed each year: The City has averaged two spills per year since 2020. The City cleans 85-100% of its lines yearly. The City intends to hire a CCTV contractor to inspect the system beginning in 2026, after which the City will evaluate the ﬁndings to determine an optimal inspection interval.

Prioritize condition assessment areas : There is a 5-mile-long lagoon running through the City. The City inspects all its lift stations monthly and inspects its larger lift stations (e.g., 22 and 29) more frequently.

Assess system using visual observations, etc.: The City assesses system conditions using visual observation of manholes and lift stations. The City intends to resume assessing the system using CCTV in 2026.

Evidence of ﬂow exiting from system: The City is not aware of any exﬁltration from its system. However, due to the high groundwater table, inﬁltration is possible. If the groundwater table drops below the sewer pipe, then there is the potential for exﬁltration. The City will continuously monitor for evidence of exﬁltration and if found, will address the issue.

Maintain documents: The City currently maintains paper and electronic (Excel) records. The City intends to transition to Cartegraph, which will allow all data to be tracked and readily available to all City staﬀ. The City intends to have its CCTV contractor use the PACP defect coding for the gravity lines and MACP inspections for the manholes. The contractor will provide video and inspection logs to the City.

Climate change: The City has considered the potential eﬀects of climate change on its collection system.

Given the City’s location along the edge of San Francisco Bay, sea level rise is a major concern. However, in 2024 the City completed a capital improvement project to raise and strengthen its entire levee system which should protect the City from sea level rise for the foreseeable future. Upgrades to the lagoon pumphouse are currently in the design phase. This will include the addition of up to two pumps to the existing 2 pumps, in order to increase the City’s resiliency to Sea Level Rise and heavy storm events . The City has also considered the impact of power outages and has installed permanent emergency generators at 14 lift stations and has two newer and two older portable generators available for the other lift stations. The City has previously experienced power outages and has been able to keep its entire collection system functioning using the permanent and portable generators. The City should not have issues with erosion or wildﬁre.

• 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 above-ground 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.”

COMPLIANCE
The City completed a Wastewater Collection System Master Plan in 2019. Among other items, the Master Plan addresses both dry weather and wet weather ﬂow monitoring, ﬁeld inspections, appropriate design capacity, existing data, impacts of inﬂow/inﬁltration on the system, and redundancy in pumping for an existing lagoon crossing.

The Master Plan identiﬁes and prioritizes capacity and rehabilitation improvement projects and recommends a phased capital improvement program, including budget estimates, for implementing the needed capacity improvements to the wastewater collection system.

The Master Plan includes a n assessment to determine the condition of 20 City lift stations, recommend improvements, and prioritize future lift station CIP projects. These 20 lift stations have exhibited operational problems, shown signs of deterioration, or have other deﬁciencies that need to be corrected.

In addition, the City identiﬁed a list of 20 collection system hot spots that require monthly maintenance to sustain standard operations. The result of the assessment was a comprehensive list of impro vement projects needed to address the deﬁciencies at the lift stations and collection system hot spots.

COMPLIANCE
Spills. When the City experiences a spill, it implements its SERP which includes taking measures to prevent the public from accessing the spill location. Staﬀ will put out barricades and caution tape and remain on site to provide an additional safety factor until appropriate authorities respond and direct otherwise. The City also has the ability to turn oﬀ the force main to stop the spill. The City’s communication team are able to send a “blast” email and make calls to notify residents.

Public participation. There are several opportunities for stakeholders and the public to participate and provide input into the development and update of the City’s SSMP. During its initial development stage, as with each SSMP Audit and update of the SSMP, the SSMP and related documents are presented to the City Council for review and acceptance. Prior to each City Council Meeting, these documents are included in an Agenda packet which are readily available for review on the City’s website.

The City publishes its SSMP, available for public review, on its website on the Public Works wastewater management plan page. The City also maintains a paper copy of the SSMP in its oﬃces which can be made available for inspection during regular business hours.

Satellite systems. The City does not have any satellite system.
