• GOAL EM-7 Effective Wastewater Treatment
Continue to operate and maintain the water pollution control plant, using cost effective methods, so that all sewage and industrial wastes generated within the city receive sufficient treatment to meet the effluent discharge and receiving water standards of regulatory agencies. • POLICY EM-7.1 Monitor water pollution control plant operations and maintenance to meet regulatory standards.
• POLICY EM-7.2 Coordinate operating procedures with the city energy policy to optimize an alternative energy program so that minimum use and reliance are placed on outside energy sources.
• POLICY EM-7.3 Actively participate in the watershed management approach to solving water quality issues of the Santa Clara Basin watershed and the South Bay. • POLICY EM -7.4 Produce quality recycled water and seek to maximize the use of this resource.

1.3 Sewer System Asset Overview
The City is located in Santa Clara County at the south end of the San Francisco Bay. It is an urban, industrial, and residential community serving a population of approximately 157,566 within approximately 23 square miles.

The City maintains a record of its assets within a Geographical Information System (GIS) geodatabase that includes information for wastewater collection system assets including: gravity line segments, manholes, pumping facilities, and pressure pipes (force mains). The City also has GIS information for the storm drainage system. A collection of block maps is maintained on the City’s website that detail the sewer and storm drainage systems, located at the following link:
https://www.sunnyvale.ca.gov/city-services/online-services/maps-and-gis/utility-maps.

The City is in the process of implementing a computerized maintenance management system (CMMS) for purposes such as generating work orders, tracking sewer pipeline maintenance issues, and other operations and maintenance (O&M)-related functions. The new CMMS system is planned to be operational in 2025.

The City provides wastewater service to all customers within City limits as well as portions of the City of Cupertino to the south of the City known as the “Rancho Rinconada” area. In 2022, the City diverted sewer flow from a portion of Rancho Rinconada ( 91 homes) in the area west of E .

Estates Drive and north of Bollinger Road to flow into Cupertino Sanitary District (CuSD)’s collection system. The wastewater previously flowed through an aging pipeline suspended over Calabazas Creek which is slated for removal. A new diversion system was implemented which consisted of construction of 20 feet of new 8-inch pipeline at E. Estates Drive, install ation of a diversion weir in a CuSD manhole to reroute approximately 15% of the combined flow, and refurbishment of existing infrastructure such as repair of an unused 8-inch pipe along S. Tantau Avenue.

A breakdown of the number of service connections by customer type is provided in Table 1-2.

Land Use Type Number of Connections Number as Percentage Residential 28,133 94%
Commercial 1,691 6%
Industrial 28 < 1%
Total 29,852 100%
The sewer service area boundary is presented in Figure 1-1. Wastewater is treated at the WPCP where it is either distributed back to the City for recycled water uses or discharged to the San Francisco Bay (Bay) under NPDES Permit No. CA0037621.

The total collection system is about 310 miles of gravity pipeline – approximately 296 miles within City limits and 14 miles in the Rancho Rinconada area – ranging in size from 4 -inch to 48-inch diameter. Within the City, there are approximately 10,719 feet of force main, 5 pump stations, and 11 active siphons.

Table 1-3 and Table 1-4 provide breakdowns of the existing pipelines by diameter and material, respectively, according to the City’s GIS records. Data regarding the exact age of the City’s sewer system is inexact; however, the average age is estimated t o be over 50 years for City pipelines based on the City’s incorporation in 1902, development records, historical population growth, and GIS records, and 70 years for Rancho Rinconada pipelines based on development records.

In addition, there are nearly 20 miles of privately -owned sewers tributary to the system included in the City’s GIS, plus additional private sewers not in GIS associated with Lockheed Martin and mobile home parks.

A map of the sanitary sewer system is included in Appendix A of the SERP (see Appendix 6).

Sewer Service Laterals: Sewer service laterals within the City’s collection system are owned by, and therefore the responsibility of, the property owner to maintain and assure serviceability.

The City may provide maintenance services to laterals located within the public right-of-way as a courtesy service to City and Rancho Rinconada residents only if a property line cleanout exists, and the cleanout and adjacent area are accessible to City staff and equipment . The City may provide maintenance, repair, rehabilitation, and/or replacement of the “lower” portion of private sanitary sewer laterals within the City that are located within the public right -of-way on a discretionary basis. The City does not install any type of cleanout on private sewer laterals.

Table 1-5 lists the number of laterals within the City and Rancho Rinconada.

Stormwater: Portions of the City’s sanitary sewer system also collect stormwater from two principal sources:

1. A known pipe cross connection from the storm drain system to the sanitary system on Borregas Avenue at E. Weddell Drive; and

2. Direct stormwater discharges from the Northrup Grumman property near Fair Oaks Avenue and E. California Avenue.

While the City cannot accurately quantify the stormwater flows entering the sanitary system from these sources, estimates were developed for evaluating their potential impact on sanitary sewer pipeline capacity as part of the City’s2022 Wastewater Collection System Model Expansion and Capacity Analysis (Capacity Analysis), included as Appendix 8A.

3.2 Coordination
Easement Accessibility Agreements: The City has easement accessibility agreements in order to access collection system infrastructure that is located outside of the public right of way. These agreements are stored on -site for easy access by City staff, as needed, for any necessary emergency repairs and/or O&M work.

Stormwater Agency Coordination: The City owns and operates the storm drain system within the City boundaries. The storm system is maintained and managed by the same crew, which means the crew has immediate access to the drainage conveyance system within City limits and can contain and recover spills immediately without having to coordinate with external agencies.

Should a spill happen in the Rancho Rinconada portion of the collection system or otherwise flow outside of City limits, the spill would cross into the Santa Clara Valley Water District (Valley Water) stormwater service area. In this case, City staff would contact Valley Water to coordinate necessary cleanup activities.

Agreements with Satellite Agencies : The City has informal mutual aid agreements with the neighboring cities of Santa Clara, Los Altos, and Mountain View. The City will continue to assist any surrounding cities when requested, if able.

ELEMENT 4. OPERATION AND MAINTENANCE PROGRAM
This section provides an overview of the City’s sewer system O&M program.

General Order, Attachment D – Sanitary Sewer Management Plan Required Elements

4. OPERATION AND MAINTENANCE PROGRAM
The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.

4.1. Updated Map of Sanitary Sewer System
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.

4.2. Preventive Operation and Maintenance Activities
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.

4.3. Training
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.

4.4. Equipment Inventory
An inventory of sewer system equipment, including the identification of critical replacement and spare parts.

4.1 Updated Map of Sanitary Sewer System
The field crews use GIS database maps on mobile devices . Block maps presenting the data stored in the GIS database are available at the following link:
https://www.sunnyvale.ca.gov/city-services/online-services/maps-and-gis/utility-maps The maps include all wastewater facilities including, but not limited to:
• Pipe material, diameter, and direction of flow for both gravity and pressurized pipes; • Upstream and downstream pipe invert elevations, where available; Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
• Manholes, including rim elevations, where available; and • Pump stations.

The City has developed and implemented an ongoing system for updating sewer asset maps.

Field crews note corrections to the maps which are transmitted to a GIS consultant, and the consultant makes corrections in the GIS maps. The updated maps are then reviewed by City staff before being entered into the production database.

The link provided above also includes detailed block maps for the City’s stormwater conveyance system.

4.2 Preventive Operation and Maintenance Activities
The elements of the City’s sewer system O&M program include:
• Proactive, preventive, and corrective maintenance of gravity sewers; • Pipeline and manhole inspections;
• Rehabilitation and replacement (R&R) of sewers that are in poor condition; and • Periodic inspection and preventive maintenance of pump stations.

Currently, the City has three combination unit crews, one construction crew, one CCTV crew, one on-call personnel, and one utility locating personnel. Table 4-1 summarizes the total length of gravity pipelines cleaned and inspected over the past ten years. It is noted that there are pipelines in identified hot spot areas that are cleaned more than once annually; the lengths listed may include some reaches counted more than once.

Gravity Sewers
The City has three combination (hydro/vacuum) units used for the cleaning or maintenance of its sewer mains which can clean pipelines up to 15 inches in diameter; cleaning of larger pipelines, as well as siphons, must be contracted out. With current funding and staffing levels, the City proactively cleans the sewe r system every three to five years, and preventively cleans sewers with a history of issues on enhanced frequency cleaning intervals of two, three, or six months depending upon the specific condit ions in individual segments . Approximately 270,000 feet or Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
about 17% of the system are currently in the enhanced frequencies category. The City also contracts for the treatment of some lines that have a history of issues with roots. Currently about 35,000 feet are treated annually.

Gravity sewer maintenance is currently scheduled using maps and lists of enhanced frequency cleaning line segments. Completed sewer maintenance is recorded in field crew daily reports. A CMMS is currently in development and is planned for implementation in 2025 . This CMMS will be used to generate work orders, track history for most sewer line maintenance issues, and provide other O&M-related functions. The City’s Standard Operating Procedure (SOP) for sewer cleaning is included as Appendix 4A.

Pipeline and Manhole Inspections
Prior to April 2012, t he City used an outside contractor for CCTV inspection services for both periodic condition assessment and for follow-up after spill events. In April 2012, the City obtained its own CCTV equipment truck . ESD staff now conduct inspections in-house with assistance provided by contractors as necessary. ESD staff have been trained in the use of the CCTV equipment. The City’s SOP for CCTV inspections is included as Appendix 4B. City staff that operate the CCTV equipment are trained and certified in the NASSCO PACP coding system that is used internationally to assess and grade the condition of pipelines.

The past several years, the City has experienced staffing shortages and equipment failures which has hampered their ability to keep up with prior pipeline inspection goals. The City has, however, made strides to improve the quality and quantity of inspections: in early 2018, the City installed new hardware and software (GraniteNet) in the CCTV truck and incorporated the latest improvements to the GIS system which has reduced the time required to complete each CCTV inspection. The City has also teamed with SewerAI to speed up the inspection process, and they have increased the number of NASSCO PACP -certified operators from four to ten. It is anticipated that these improvements will help improve the quality of inspection and inspection capacity. The current inspection cycle is approximately 10-12 years, which has largely minimized spills and successfully mitigated them when they have occurred. The City intends to continue to inspect the entire collection system using CCTV every 10 years . This provides an achievable goal for full inspection of the system that provides adequate data for proactive maintenance of the system while allowing sufficient budget and employee capacity to review and analyze all of the CCTV data and incorporate it into any necessary R&R CIP projects.

In 2011, the City committed to an aggressive schedule of manhole inspections to identify potential cross-connections between the sewer system and the storm drain system. Such connections were historically incorporated into the design of certain manholes a s a means of preventing uncontrolled spills in the event of a backup but are no longer considered acceptable. The City inspected all 7,133 manholes by the end of 2013. As part of this process, the City documented the condition of the manholes and identif ied any other issues (e.g., deterioration, excessive I/I).

Manhole inspections are now performed during routine cleaning of pipelines and as needed.

Manhole rehabilitations are part of the City’s CIP program.

Attachment 2

Rehabilitation and Replacement (R&R)
City crews or contractors correct localized problems identified by CCTV and /or sewer cleaning crews. Large scale repairs and replacements are completed in priority order and are coordinated with the City’s street resurfacing program and annual water main replacement projects. Design, bidding, and construction services for sewer rehabilitation and/or replacement projects are provided by the City’s Department of Public Works though the CIP program.

Funding for the CIP is derived from the City’s Sewer Fund which is an enterprise fund. Sewer fees are established based on projected needs and are updated periodically . The budget and project descriptions in the City’s current CIP are listed in Appendix 8B. Additional funding for special projects may be approved by the City Council on a case-by-case basis.

Pump/Lift Station Inspections and Maintenance
City crews inspect the operation of the five lift stations – Arques, Lawrence, Sunken Gardens, Baylands, and Kifer – weekly. Maintenance activities include inspecting the site, verifying pump operation, and vacuuming out grease and debris or applying de-greasers as necessary. Each pump station ha s gravity bypass capability and can be powered by trailer -mounted generators during power outages. In 2015, the City reconstructed each of the five lift stations; this included mechanical upgrades as well as upgrad es to the electrical and SCADA systems to improve operation efficiency.

4.3 Staff and Training
City staff positions dedicated to the maintenance of the collection system facilities are listed in Table 4-2. These positions also receive administrative and clerical support provided by the ESD.

Staffing and resources are constrained under current budgets but are sufficient to maintain services at an acceptable level and, with careful prioritization, to address long-term needs.

The City uses a combination of in -house classes; on the job training ; California Sanitation Risk Management Authority (CSRMA) site visits and webinars ; and California Water Environment Association (CWEA) conferences, seminars, and other training opportunities to train its Wastewater Collections staff. The City strongly encourages staff to advance their CWEA certification grade, provides financial support for certifications and attending CWEA training, and Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
provides other training and advancement opportunities . Senior staff are actively involved in leadership roles in CWEA and BACWA.

Annual training on the City’s SSMP and SERP is conducted for all wastewater collection employees. The City also maintains an ongoing safety training program that addresses both general and task-specific safety issues. The “Tailgate Schedule for Corp Yard” lists safety training activities for the Water and Sewer Systems Division and is updated annually. The 2024 Tailgate Schedule is included in Appendix 4C.

The City’s contract language requires contractors working in the wastewater collection system to provide training for their employees in the activities that may cause spills and in responding to contractor-caused spills.

4.4 Equipment Inventory
No critical replacement parts are currently warranted. The pump stations have gravity bypasses for emergency situations, and the City has informal agreements with neighboring agencies for equipment support in the event of a sewer maintenance equipment failure.

A list of the major pieces of equipment and vehicles used to support spill responses and maintenance activities is included in Section 5 of the City’s SERP which is included as Appendix

This plan provides a procedure that, when enacted in response to a spill, will reduce or eliminate public health hazards, prevent unnecessary property damage, and minimize the inconvenience of service interruptions. It provides procedures for City staff to follow when responding to, cleaning up, and reporting spills.

General Order, Attachment D – Sanitary Sewer Management Plan Required Elements

6. SPILL EMERGENCY RESPONSE PLAN
The Plan must include an up to date Spill Emergency Response Plan to ensure prompt detection and response to spills to reduce spill volumes and collect information for prevention of future spills. The Spill Emergency Response Plan must include procedures to:
• Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner;
• Notify other potentially affected entities (for example, health agencies, water suppliers, etc.) of spills that potentially affect public health or reach waters of the State; • Comply with the notification, monitoring and reporting requirements of this General Order, State law and regulations, and applicable Regional Water Board Orders; • Ensure that appropriate staff and contractors implement the Spill Emergency Response Plan and are appropriately trained;
• Address emergency system operations, traffic control and other necessary response activities; • Contain a spill and prevent/minimize discharge to waters of the State or any drainage conveyance system; • Minimize and remediate public health impacts and adverse impacts on beneficial uses of waters of the State; • Remove sewage from the drainage conveyance system;
• Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters;
• Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery;
• Implement pre -planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event; • Conduct post-spill assessments of spill response activities; • Document and report spill events as required in this General Order; and • Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update the Plan as needed.

To fulfill the new requirements of the General Order, the City published a Sanitary Sewer SERP in June 2023; it is attached as Appendix 6. Table 1 of the SERP includes a table which lists each of the requirements of the General Order alongside which section of the SERP fulfills that requirement.

The General Order requires that the SERP be reviewed, its effectiveness assessed, and the plan updated, as necessary, annually. The schedule for annual SERP updates and assessments are included in the SSMP implementation and update schedule listed in Table 1-1.

ELEMENT 7. SEWER PIPE BLOCKAGE CONTROL PROGRAM
This section of the SSMP evaluat es the extent and nature of spills related to pipe blockages including FOG, roots, and other debris such as rags, wipes, etc. It outlines the need for and the elements of the City’s Blockage Control Program.

General Order, Attachment D – Sanitary Sewer Management Plan Required Elements

7. SEWER PIPE BLOCKAGE CONTROL PROGRAM
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.

7.1 Nature and Extent of Blockage Problem
Since 2015, an average of approximately 93% of spills in the City have been caused by pipe blockages annually. Further, a majority are caused by roots (64%), FOG (22%), or a combination of both in the sewer line.

As of January 2025, the City has over 462 FSEs which are potential commercial and industrial sources of FOG discharging to the wastewater collection system. FSEs include eating and drinking establishments, cafeterias, bakeries, delis, meat preparation, mobile facilities, and one sausage manufacturer. The largest concentration of commercial FOG sources are FSEs located in the vicinity of Murphy Ave and along portions of El Camino Real. Some are located in older buildings and have undersized grease traps.

7.2 Blockage Control Program
Approximately 17% of the collection system’s pipelines are currently on the enhanced frequency cleaning listings (60-day, 90-day, semi-annual, and bi-annual), which are used by the Wastewater Collections Program (WW Collections) to sched ule sewer line preventive maintenance. The enhanced frequency cleaning listings reside on the City network, are accessible by ESD staff, Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
and are periodically updated based on information collected during maintenance activities (particularly the results of CCTV inspections). Such periodic updating allows the City to adjust cleaning frequencies to the needs of the particular line segment and more effectively utilize maintenance resources.

To address root intrusion, the City deploys both chemical and mechanical methods, as needed.

The City also contracts for the treatment of some lines that have a history of issues with roots .

Currently about 35,000 feet are treated annually. Pipelines that have had FOG-related spills or surcharging, particularly those with multiple instances of FOG -related spills or surcharging , are placed on the enhanced frequency cleaning listings.

ESD Blockage Control Program Elements
Sewer Line Cleaning:

1. Pipe blockage information is shared between WW Collections and the Regulatory Programs Division / Compliance Inspection Group.

2. WW Collections will contact the Compliance Inspection Group for enforcement or outreach support when a spill event is in progress or has occurred.

3. WW Collections provides line blockage information to the Compliance Inspection Group for review and any follow-up.

4. WW Collections will advise the Compliance Inspection Group of any possible grease discharge or other blockages identified during mainline stoppage, follow up or general maintenance flushing, or scheduled televising wastewater segments.

5. The Compliance Inspection Group will advise WW Collections of all findings, all outreach program participants, and their findings of any investigation initiated by WW Collections or caused by concerns identified during the follow up or annual maintenance flushing of wastewater main segments.

Legal Authority – Ordinance: The SMC identifies discharge-related prohibitions and requirements. These include GRD requirements and enforcement actions. Reference to the sections of the SMC that are relevant to the Blockage Control Program and Enforcement are included in Table 3-1.

FSE Permits/Registration: The Compliance Inspection Group has identified all FSEs in the City and performs sampling, inspection, and enforcement to verify compliance with SMC and Best Management Practices (BMPs). New or remodeled FSEs are identified through a review of the Business License list in conjunction with the City’s Finance and Building Departments.

FSE Inspections/Enforcement: Currently, one Senior Environmental Compliance Inspector and six Environmental Compliance Inspectors conduct FOG Program inspections . Since 2011, the Compliance Inspection Group has inspected most FSEs on an annual basis . FSEs that are considered low FOG are inspected at least once every three years . Low FOG facilities include businesses that do not cook and use disposal food ware with no dishwashing. Although unrelated to General Order compliance, the Compliance Inspection Group also inspects FSEs for Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
compliance with stormwater BMPs concurrent with FOG inspections. During FSE inspections, the emphasis is on:

1. GRD installation and maintenance;

2. Process information;

3. Grease management; and

4. BMPs.

Enforcement actions are clearly outlined in the City’s Pretreatment Inspection Enforcement Response Plan which was most recently revised in February 2024 and a copy of which is included in Appendix 7. Elements include:

1. Identifying and investigating instances of noncompliance;

2. Enforcement procedures; and

3. Enforcement response guide.

A summary of inspections and enforcement actions over the past ten years is included in the following table.

Notes:

1. Includes both routine and follow-up inspections.

Grease Interceptor and Trap Installation Requirements : All GRDs installed or cause d to be installed are sized in conformance with the currently adopted edition of the Uniform Plumbing Code (SMC 12.12.026). The Compliance Inspection Group coordinates with the Building Division in the permit review of FSEs.

Grease Interceptor and Trap Maintenance Requirements: In accordance with SMC 12.12.026, all GRDs installed or caused to be installed shall be kept in good repair and shall be maintained in continuous operation. The GRD contents shall be removed every six months at a minimum, and documentation of all grease removal activities shall be maintained . The Environmental Compliance Inspectors inspect FSEs for these criteria . Inspectors review cleaning records for GRDs and if records or other observations indicate insufficient cleaning, inspectors may conduct FOG accumulation measurements of the GRD. The City requires compliance with the 25% rule BMP, that is, FSEs are required to maintain their GRDs below 25% total capacity of measured solids and FOG. Any measurement above 25% indicates that the cleaning frequency of the GRD Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
is not adequate and requires an immediate pump out and, potentially, an increased maintenance frequency.

Grease Hauling and Disposal Requirements : It is unlawful for any person to dispose of any grease by discharge into any sanitary sewer or storm drainage system (SMC 12.12.025).

1. Environmental Compliance Inspectors review the contracted grease hauling and disposal company documents when conducting an FSE inspection.

2. FSEs that conduct self-cleaning of GRDs are provided guidance regarding proper disposal of the FOG.

Grease Hauling and Disposal Facilities : The nearest disposal site for FOG is Silicon Valley Clean Water (SVCW) in Redwood City. Other local facilities that accept FOG from outside their service areas include the East Bay Municipal Utility District (EBMUD) in Oakland and the City of Watsonville Wastewater Treatment Facility.

Kitchen BMP Requirements : Kitchen BMP activities are observed and related questions are asked during inspections of FSEs. All FSEs receive BMP documents regarding FOG reduction, and the BMPs are published in multiple languages.

Residential Program : The Compliance Inspection Group previously conducted surveys and inspections of residential complexes located in FOG “hot spots,” as identified by WW Collections.

These facilities receive information on BMPs, and their effectiveness will be monitored.

Education and Outreach: The Environmental Programs Specialist works with the Compliance Inspection Group in selecting and distributing both FSE and residential complex BMPs related to FOG reduction. In addition, FOG outreach regularly occurs as articles in City newsletters, social media, newspapers, and utility bill inserts.

ELEMENT 8. SYSTEM EVALUATION, CAPACITY ASSURANCE, AND CAPITAL

IMPROVEMENTS
This section outlines the City’s programs and activities to ensure adequate capacity of all facilities by evaluating the condition of the system as well as the hydraulic capacity.

General Order, Attachment D – Sanitary Sewer Management Plan Required Elements

8. SYSTEM EVALUATION, CAPACITY ASSURANCE AND CAPITAL IMPROVEMENTS 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
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:
o Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;
o Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas;
o 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 methods;
• Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State; • Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and
• 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.

8.2 Capacity Assessment and Design Criteria
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;
Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
• 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.

8.3 Prioritization of Corrective Action
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.

8.4 Capital Improvement Plan
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.

8.1 System Evaluation and Condition Assessment
The City’s system evaluation and condition assessment process is detailed in Element 4 as part of the preventive O&M program. This includes pipeline CCTV inspections on a ten -year cycle, manhole inspections, pump/lift station inspections and maintenance, and R&R projects developed as a result of these inspections.

8.2 Capacity Assessment and Design Criteria
To fulfill the requirements of Element 8 of the SSMP, the City conducted a Wastewater Collection System Model Expansion and Capacity Analysis (Capacity Analysis) – included as Appendix 8A – which was finalized in December 2022 as an update to the analysis completed in the 2015 WWMP. The objectives of the 2022 Capacity Analysis were:
• To develop wastewater flow projections for the City’s sewer service area using up -to-date development and land use information and flow monitoring data; • Develop an updated hydraulic model of the trunk sewer system; • Use the model to identify existing capacity deficiencies and future capacity requirements; and • Develop a capacity improvement plan, including project priorities and planning level estimates of construction and capital costs.

8.3 Prioritization of Corrective Action and Capital Improvement Plan The CCTV footage and inspection data is used to develop R&R projects based on pipe condition.

Pipes with severe defects (rated 4 or 5 on the NASSCO PACP rating scale) are prioritized for rehabilitation. Pipes with multiple severe defects are further anal yzed; if there are too many defects and a full manhole-to-manhole replacement is deemed necessary, the pipe is added to a CIP list which goes out for bid every three years.

Attachment 2

City of Sunnyvale
Sewer System Management Plan
April 2025

www.hydroscience.com
As part of the 2022 Capacity Analysis, a set of CIP projects was developed based on hydraulic deficiencies identified in the model in both existing and future development scenarios. Details on the prioritization of projects can be found in Section 5.2 of the Capacity Analysis included as Appendix 8A.

Since the completion of the Capacity Analysis, the City has developed a 20 -year CIP budget projection for sewer capacity enhancement projects. Specific projects were identified, prioritized, and scheduled within the limitations of the budget. The 20-year CIP is reviewed and adjusted on a two-year cycle.

As they are funded by separate accounts, R&R projects based on pipe condition are analyzed and implemented separately from capacity-related hydraulic deficiencies. The current schedule for the City’s R&R and capacity enhancement projects is included in the City’s annual budget which is approved by City Council. Annual funding is also programmed in the budget to address emergency repairs on an as-needed basis. A listing of the annual budgets and project description for Wastewater System CIP projects from the City’s FY 2024/25 approved Budget and Resource Allocation Plan is included as Appendix 8B.

ELEMENT 9. MONITORING, MEASUREMENT, AND PROGRAM MODIFICATIONS This section of the SSMP outlines the process that the City will follow to evaluate the effectiveness of the SSMP and to identify updates that may be needed for a more effective program.

General Order, Attachment D – Sanitary Sewer Management Plan Required Elements

9. MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS
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.

9.1 Performance Measures
The statistics that the City will use to measure the performance of its wastewater collection system and the effectiveness of its SSMP are:
• Total number of spills;
• Volume of sewage spilled, recovered, and reaching water of the State; • Locations with multiple spills;
• Number of spills broken down by cause (roots, debris, FOG, pipe structural issues, etc.); and • Annual pipeline cleaning and inspection lengths (see Element 4).

Table 9-1 summarizes the annual statistics for spills over the past ten years. For this period, the City averaged 5.8 spills annually with a high of 1 1 in 2022, and a low of three in both 2015 and 2016. Though there is fluctuation from year to year, in general, the number of spills has remained relatively low and consistent in both recent years and in the longer-term average. 2021 saw only four spills which is lower than both the recent and longer-term average. The high number of spills in 2022 may be attributed to changes in wastewater discharge patterns and staffing shortages due to COVID-19, preventing the full menu of preventive O&M activities from being implemented.

As of 2024, the City has returned to full staff and has resumed all preventive O&M activities.

In addition to these performance measures, the City internally considers additional measurements such as emergency response times to ensure the best response to a spill.

Figure 9-1 provides a visual representation of spills by volumes: total, recovered, and unrecovered. During the five -year period from 2009 to 2013, the total spill volume averaged 12,624 gallons/year and the percentage of spill volume recovered averaged 88%. Since 201 5, the total spill volume has decreased substantially to 3, 742 gallons/year and the percentage of volume recovered has increased to 100%. The reduction in volume and the increase in overall recovery can be attributed to the programs that the City has implemented as part of the SSMP and speaks to the effectiveness of staff training in spill response and recovery and SSMP programs in general. These changes indicate the success of the City’s SSMP in minimizing the number and volume of spills and implementing proper procedures to respond to and contain spills when they do happen.

It is noted that though the number and volume of spills continues to fluctuate from year to year, no spills have been discharged to surface waters since 2012, and no volume has been unrecovered since 2013.

Figure 9-1: Spills by Volume

The cause of all spills over the past ten years is summarized in Table 9-2 and Figure 9-2. Roots are the most common cause of spills for all years. The City implements regular maintenance of the collection system and deploys both chemical and mechanical methods for addressing root intrusion, as needed.

ELEMENT 10. INTERNAL AUDITS
This section outlines the City’s SSMP auditing program.

General Order, Attachment D – Sanitary Sewer Management Plan Required Elements

10. INTERNAL AUDITS
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.

General Order, Section 5.4 – Sanitary Sewer 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.

10.1 Audits
The City conducted annual audits of the SSMP from calendar years 2008 through 2011; beginning in 2012, the audits were conducted biennially. The latest audit was submitted October 2024, and in compliance with the new requirements of the General Order, SSMP audits will continue every three years moving forward. The schedule for completing SSMP audits is included in the SSMP implementation and update schedule listed in Table 1-1.

SSMP audits are due November of the year following the monitoring period; the monitoring period is the previous three calendar years. Thus, the next audit will evaluate the monitoring period of January 1, 2024 through December 31, 2026 and will be submitted by November 2, 2027. Audits have historically been conducted by the City’s Wastewater Operations Manager and/or an outside consultant with the support of the City’s Wastewater Collections Supervisor; other parties may be added to future audit teams.

An audit checklist, adapted from a document developed by BACWA and based on the requirements of the General Order is used to evaluate each element of the SSMP. The checklist focuses on evaluating the compliance, implementation, and effectiveness of each element with a Attachment 2

set of questions, each answered with a “Yes/No” response and supported by notes to explain any deficiencies and/or provide supporting context or detail. In addition to the checklist, spill data is provided that provides key performance indicators , accompanied by a discussion to measure/evaluate the overall effectiveness of the SSMP during the monitoring period. Finally, a summary of any deficiencies identified is provided , each with a corresponding corrective action and scheduled completion date.

Per the new requirements of the General Order, the audit is submitted to the online CIWQS Sanitary Sewer System Database. Internally, t he Wastewater Operations Manager retains the audit for City records. The audit serves as the primary tool for documenting SSMP effectiveness as described in Element 9.

10.2 SSMP Updates
As part of the audit process, City staff will update critical information in the SSMP per any deficiencies identified in the audit. In general, information expected to require regular routine updating (contact lists, performance statistics, Enhanced Frequency Cleaning lists, etc.) is included in the SSMP as appendices or referenced to external documents to facilitate the update process and reduce the frequency that the body of the SSMP will require updating. All updates to the SSMP will be tracked in a Ch ange Log. Consistent with the audit, t he Wastewater Operations Manager is responsible for maintenance and updating of the SSMP and the Change Log.

The SSMP will be comprehensively updated every six years moving forward per the new requirements of the General Order, i.e., the next major update will be in 2031. This submittal is included in the SSMP Implementation and Update Schedule provided in Table 1-1. Changes made to the SSMP as part of this update are documented in the Change Log located in Appendix 10A.

1. Introduction
The City of Sunnyvale (City) owns and operates the sanitary sewer system within the City boundary as well as a small area in the City of Cupertino. The system consists of about 310 miles of gravity pipes, 2 miles of pressured pipes (i.e., siphons and force mains), over 7,000 manholes, and five pump stations; a map of the system is included as Appendix A of this document . The system is operated and maintained by th e Environmental Services Department ’s (ESD’s) Water and Sewer Division (Division) ; whereas the sewer service laterals are owned by, and therefore the responsibilities of, individual property owners.

Pursuant to the Statewide Sanitary Sewer Systems General Order 2022-0103-DWQ, attached herein as Appendix B, public entities that own and/or operate one or more sanitary sewer systems, such as the City, are required to update and implement a Spill Emergency Response Plan (SERP) within six months of the adoption date of the General Order, which is June 5, 2023. Ta ble 1 provides a summary of the SERP requirements outlined in Attachment D -6 of the General Order. The City is required to keep the SERP on file internally but is not required to submit it to the State. The City is, however, required to certify that the SE RP is up to date in its Annual Report (the next one is due on April 1, 2024), and include it in its Sanitary Sewer Management Plan (the next SSMP is due in June 2026).

Table 1: Required Procedures per Attachment D-6 of General Order 2022-0103-DWQ No. Procedure Section(s)
1 Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner; 2, 4

Attachment 2

2. Sanitary Sewer Spill Notification Procedures
The City is committed to meeting the spill notification requirements outlined in Attachments E1 and E2 of the General Order. To achieve this goal, the City has implemented several measures, including providing multiple platforms for the general public to report potential sewer spills or surcharges, training a crew of qualified staff (aka responders) to respond to spill incidents, and possessing a fleet of vehicles and large equipment to contain and cleanup spills. The City has also appointed three data submitters and two Legally Responsible Officials (LROs) to ensure spill incidents are promptly reported to the appropriate personnel and agencies. Furthermore, the City also maintains one responder on after-hour standby shifts to make sure spill incidents can be addressed promptly even after hours and retains a list of qualified contractors that could assist with emergency response s and repairs on an as needed basis. The City’s responders, data submitters, and LROs responsible for the implementation of the spill notification procedures are identified in Appendix C along with their contact information. A list of qualified contractors is included in Appendix D.

2.1. Informing Potential Spill Incidents to Responders and Local Officials The City can be notified of potential sewer spill s through multiple venues. S pills can be reported by residents or businesses via the City’s Customer Relationship Management (CRM) system, which has a utility services hotline (408- 730-7400) as well as an online portal (https://sunnyvale.dynamics365portals.us/utility/). Sewer staff are also trained to identify spills and surcharges during their daily assignments . The City also has a Supervisory Control and Data Acquisition (SCADA) system that sends alarms to staff if an issue is detected at one of the pump stations.

Once notified, responders are required to report to the site and assess the situation. If a spill is confirmed, staff must report the spill to the Wastewater Collections Supervisor (supervisor), secure the spill area, follow protocol to control or halt the cause of the spill, and clean the spill as soon as possible. Detailed procedures on how to control and clean the spill are included in Section 3 of this document.

If industrial toxic substances are involved, any volume must be immediately reported to the Department of Public Safety (DPS) Hazardous Materials Response Team.

The supervisor will notify the LROs of the incident, who will be responsible for notifying applicable City staff about the incident. This includes, but are not limited to, the ESD director, the Water Pollution Control Plant if the spill would impact the plant, the DPS Communications Team if public notices and media correspondences are needed, and ESD’s Compliance Inspection group if the spill is determined to be caused by fats, oils, and/or grease (FOG).

2.2. Notifications of Spill Incidents to Regulatory Agencies and Potentially Affected Entities Specific notification and reporting procedures depend on the severity and location of a spill. Detailed procedures are included in Section 4 of this document. In general, the LROs are responsible for reporting all spills using the California Integrated Water Quality System ( CIWQS) online platform. Spills greater than or equal to 1,000 gallons that either discharge or threaten to discharge to surface water must also be reported by phone to the California Office of Emergency Services (Cal OES) within two hours of initial knowledge of such incident.

In addition to regulatory agencies, the LROs are also responsible for notifying the following potentially affected entities:
• If spills resulted in a discharge of sewer of any volume to any of the waterways, the LROs will notify the Santa Clara Valley Water District via their Pollution Hotline at 1-888-510-5151. • Sunnyvale shares borders with the City of Mountain View on the west, the City of Santa Clara on the east, and the City of Cupertino on the south . The crew supervisor maintains a contact list of collection system supervisors of these cities. If a spill is determined to have impacted or have the potential of impacting any of the cities, the supervisor and the LROs will contact these entities to coordinate response efforts.

The City owns and operates the storm drain system within the City boundaries . The storm system is maintained and managed by the same crew , which means the crew has immediate access to the drainage conveyance system and can contain and recover spills immediately without having to coordinate with any external agencies. A flow chart illustrating the chain of communications throughout a spill response procedure is included in Figure 1.

3. Sanitary Sewer Spill Emergency Response Procedure
The sanitary sewer spill emergency response procedure s described herein shall be followed for all spills, including those involving discharge from industries into the City’s sanitary sewer or storm systems. An abbreviated version of the procedure is included as Appendix E and a copy of which will be kept in City vehicles.

3.1. Safety
Whenever qualified City personnel respond to a report of a spill, they may encounter an emergency situation that requires immediate action. The most critical aspect of resolving an incident of this nature is to safely and competently perform the actions necessary to return the system or facility to normal operations as soon as possible in order to minimize public health and environmental impacts.

The most important item to remember during this type of incident is that safe operations always take precedence over expediency or shortcuts. Worker and public safety also take precedence over regulatory notifications and reporting.

Upon arrival at a spill site, the responder will conduct a hazard assessment to determine potential safety hazards, including the possibility that a spill may contain unknown hazardous waste or chemicals. On rare occasions, gasoline and industrial solvents have been found in the sewer system. If a hazard is suspected, the responding field crew should notify DPS Communications immediately and request the DPS Hazardous Materials Response Team to assist.

The LROs should also be notified of a spill as soon as possible. Personnel shall stay clear of any hazards and secure the area from the public.

Depending on the nature or cause of the spill, personnel may be required to remove a mainline blockage with a hydro- flusher, repair a damaged section of pipeline, or wash/clean a City s treet. At this point, it is essential that all standard safety procedures and/or duties be followed as deemed appropriate.

Typical responses may require personnel to implement the following types of safety procedures:
• Standard personal protective equipment (PPE),
• Confined space entry procedures,
• Traffic control,
• Heavy equipment operation, and/or
• Adequate communication via two-way radio and/or cellular telephone.

In summary, all personnel must diligently adhere to the following safety protocols prior to commencing any work:
(a) Personal Protective Equipment (PPE): Every individual must confirm that they are equipped with the appropriate personal protective gear suitable for their assigned tasks. (b) Safety Signage and Warning Devices: Prior to initiating any work, personnel must verify that all safety signs and warning devices are correctly installed and operational. (c) Field Observations and Documentation: Upon arrival at the site, personnel are encouraged to conduct thorough field observations, paying special attention to any spills or hazardous incidents. It is advised to capture photographs or other suitable documentation to ensure proper record-keeping.

3.2. Control the Cause of the Wastewater Spill
(a) Set out absorbent materials (e.g., Spill Shark) to contain the sewage overflow and prevent sewage runoff from entering into the storm system.
(b) Do whatever is necessary to correct the origin of the wastewater spill, or, if the overflow is caused by a stoppage in the sewer collection main, call for assistance and use the hydro- flushing truck to rel ieve the stoppage immediately.

Attachment 2

3.3. Main Line Stoppage and Overflow
(a) Check upstream and downstream manholes to determine between which two manholes the stoppage exists. (b) Flush or rod from first clear downstream manhole towards stoppage. (c) Capture and remove all debris if possible. If this cannot be done, check the downstream manholes for any sign of restrictions or the possibility of a second mainline stoppage. Where possible, flush the debris down to a larger main for better access.
(d) Immediately flush the area and wash down manholes and street, contain and remove any solid debris. Wash water is contained and disposed of using the Combo Unit and return to sewer main. (e) Collect as much of the SSO as possible and dispose back into the sanitary sewer system, estimating how much was captured and placed back into the sanitary sewer system. (f) Sanitize affected area if necessary.

3.4. Lateral Stoppage
(a) Check upstream and downstream manholes. If clear, stoppage must be in private sewer lateral or building plumbing.
(b) Check lateral and perform curtesy services if deemed safe . If lateral is clear, advise the property owner that the problem is likely in the building’s plumbing, and therefore their responsibility to correct. (c) When the cleanout is buried, inaccessible, non -conforming, or non-existent, the resident should be advised that the main line is clear and it is the responsibility of the property owner to clear the blockage in the private lateral. This may require the owner providing or installing appropriate access to the private sewer lateral for servicing.
(d) If a right-of-way cleanout exists and is accessible, the City may attempt to rod the lateral to the main and clear any stoppage that may exist as a courtesy service. If City staff cannot clear the stoppage, the property owner should be advised that the City lines are clear and it is the responsibility of the property owner to correct the problem in the private plumbing.
(e) If the stoppage or structural defect is in the portion of the lateral in the public right-of-way, the City may repair the line on a discretionary basis.

If City staff cannot resolve a lateral stoppage or structural defect, the City will turn the project over to the property owner and the property owner will have to complete the project at their expense.

3.5. Clean-up and Mitigation
(a) To minimize health hazards to the public and to protect the environment, start cleaning the wastewater spill area as soon as possible.
(b) Inspect the storm drain catch basins to determine whether wastewater has entered the storm system, and to what extent.
(c) Install air plugs or sandbags in storm lines to contain the discharge and/or wash water. Flush the area with water and vacuum up the excess or pump it back into the sanitary sewer collection system. (d) Remove all debris found in the wastewater spill area by vacuuming the surface area and disposing of the material as appropriate.
(e) Thoroughly inspect and sanitize the spill area before leaving.

Attachment 2

3.6. Sampling and Lab Tests
In the event of a spill reaching surface waters or drainage channels that could cause significant impact on water quality, water samples will be collected per steps and requirements outlined in Attachment E1 of the General Order (Appendix B), as long as staff deem it feasible and safe to do so. Specifically, water quality sampling will be conducted within 18 hours of initial knowledge of the spill if an estimated 50,000 gallons or more are discharged into surface water s or drainage channels. Water samples will be collected by the City’s Regulatory Programs Division (RPD) Laboratory or Compliance Inspection staff, who are trained in field sampling procedures. Furthermore, samples will be collected in accordance with sections 2.3.2 and 2.3.4 of Attachment E1 of the General Order and be analyzed for constituents specified in section 2.3.3 of the same attachment, and at the City's RPD laboratory , which is an Environmental Laboratory Accreditation Program (ELAP) certified laboratory.

Ideally, samples should be collected at the point of discharge and at upstream and d ownstream locations. The upstream location should be far enough from the spill to be unaffected by the spill. The appropriate number and location of downstream samples will depend on various factors including spill volume, volume or flow rate of receiving water, sample access, etc. Ideally, a “near field” downstream sample (e.g., 100 -ft downstream) and one or more “far field” samples (e.g., 500-ft, 1000-ft) should be collected. If tidal conditions are such that it is unclear as to what is “upstream” and “downstream” from the discharge location, analysis for conductivity may be useful.

Samples should be analyzed for ammonia, dissolved oxygen, and a bacterial indicator, preferably Enterococcus (the Laboratory is set up to perform both Enterococcus and total coliform analyses. The enterococcus analysis is preferred to characterize SSO impacts). Field observations should also be made at each sampling location, including any visual evidence of the spill, presence of odor, or evidence of fish kills. Follow-up sampling should be conducted on successive day(s) (or at other appropriate time intervals). Such sampling is used to document when conditions return to normal, or to establish that downstream levels of ammonia and the bacterial indicator are approximately equal or less than upstream levels, or less than the applicable limits for the appropriate beneficial use. Limits for ammonia are identified in the May 2017 Water Quality Control Plan (Basin Plan) for the San Francisco Bay Basin Plan. Applicable bacteriological limits, which supersede the Basin Plan, are identified in the February 2019 Bacteria Provisions for the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries of California. The limits are summarized as follows:
• Un-ionized ammonia: 0.4 mg/l as N, south of the Bay Bridge. • Escherichia coli (E. coli): The ba cteria water quality objective for all waters where the salinity is equal to or less than 1 part per thousand (ppth) 95 percent or more of the time during the calendar year is: a six -week rolling geometric mean of E. coli not to exceed 100 colony forming units (cfu) per 100 milliliters (mL), calculated weekly, and a statistical threshold value (STV) of 320 cfu/100 mL not to be exceeded by more than 10 percent of the samples collected in a calendar month, calculated in a static manner. • Enterococci: The bacteria water quality objective for all waters where the salinity is greater than 1 ppth more than 5 percent of the time during the calendar year is: a six- week rolling geometric mean of Enterococci not to exceed 30 cfu/100 mL, calculated weekly, with a STV of 110 cfu/100 mL not to be exceeded by more than 10 percent of the samples collected in a calendar month, calculated in a static manner Field staff will exercise their best judgment in deciding whether to conduct sampling and consult with the crew supervisor and/or the LROs. Water quality sampling should not be given precedence over stopping the spill, worker safety, or protection of public health. However, if sufficient personnel are available, sampling can be conducted in parallel with the clean-up effort.

3.7. Traffic Control during and after Clean-Up (Sign Posting and Barricading) (a) To limit public interference with clean-up activities or exposure to spills, secure the area with barricades and/or yellow caution tape.
(b) If the spill has entered an open creek, post warning signs and secure the area with barricades and/or yellow Attachment 2

caution tape. Do not remove the signs or barricades until the results of the lab tests show the area to have returned to background levels.

3.8. Recordkeeping and Follow-Up Work
To ensure proper documentation and follow-up work, the responders are required to complete a Spill Response Report (aka "yellow form") for all system blockages resulting in spills or a Surcharge Response Report (aka “green form”) for blockages that do not result in spills. They can be found in Appendix F and Appendix G, respectively. The completed reports should be submitted to the supervisor and LROs for review and determination of appropriate follow-up work.

After each spill or surcharge incident, a follow-up flushing must be conducted and documented in the City's operation and maintenance (O&M) database. Additionally, the affected pipe segment should be scheduled for CCTV inspections to determine any necessary follow -up work required to maintain the segment in a clear condition. Based on the inspection results, the recommended follow-up work will be scheduled, or the line segment will be added to one of the enhanced frequency cleaning lists, such as the 60-day, 90-day, or semi-annual lists, if needed.

For any mainline blockage that causes property damage, an evaluation will be conducted, and appropriate follow -up work will be scheduled, including spot repairs, structural pipe repairs, root sawing, and root foaming, as determined by CCTV inspections.

Responders and supervisor will also reconvene after each spill incident to evaluate the notification and response procedures, including identifying what worked, what did not work, and what can be improved. A Post-Spill Assessment form is attached in Appendix H. Recommended changes will be brought forward to the LROs, who will decide if the changes should be incorporated into future response procedures, at which time the supervisor will update the SOP and the LROs will update the SERP.

All Spill Response Reports, Surcharge Reports, and other related reports will be compiled and maintained in binders and/or a digital O&M database for a period of five (5) years.

4. Sanitary Sewer Spill Regulatory Notifications, Monitoring, Reporting, and Record Keeping In addition to notifying regulatory agencies and potentially affected entities identified in Figure 1, the LROs are also responsible for monitoring and reporting spill incidents according to the category of the spill , which is summarized in Table 2. Specific notification, monitoring, reporting, and recordkeeping requirements for each spill category are summarized in Table 3. Details of these requirements can be found in Attachment E1 of the General Order, which is attached as Appendix B of this document.

In general, responders will document all spill incidents using the City’s Spill Response Report in Appendix F. In the event that the reported incident is determined to be a surcharged manhole but does not result in a spill, the responder will report the incident using the City’s Surcharge Response Report in Appendix G.

Once the report is completed, t he Wastewater Collection S upervisor is responsible for reviewing and verifying the accuracy of the draft and submitting the final draft to the LROs for approval. Once approved, the Data Submitter will report the incident to the online CIWQS Sanitary Sewer System Database, and the LRO will certify the Spill Report within the timeframe specified in Attachment E1 of the General Order.

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
4 1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures.

Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.

Sewage contains high levels of suspended solids, non-digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants.

For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State, and the environment.

This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance improvements; and
• Report noncompliance with this General Order per reporting requirements.

Attachment 2

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
5 An Enrollee is a public, private, or other non-governmental entity that has obtained approval for regulatory coverage under this General Order, including:
• A state agency, municipality, special district, or other public entity that owns and/or operates one or more sanitary sewer systems:
o greater than one (1) mile in length (each individual sanitary sewer system); o one (1) mile or less in length where the State Water Board or a Regional Water Board requires regulatory coverage under this Order; or • A federal agency, private company, or other non-governmental entity that owns and/or operates a sanitary sewer system of any size where the State Water Board or a Regional Water Board requires regulatory coverage under this Order in response to a history of spills, proximity to surface water, or other factors supporting regulatory coverage.

For the purpose of this Order, a sanitary sewer system includes only systems owned and/or operated by the Enrollee.

2. REGULATORY COVERAGE AND APPLICATION REQUIREMENTS

2.1. Requirements for Continuation of Existing Regulatory Coverage To continue regulatory coverage from previous Order 2006-0003-DWQ under this General Order, within the 60-days-prior-to the Effective Date of this General Order, the Legally Responsible Official of an existing Enrollee shall electronically certify the Continuation of Existing Regulatory Coverage form in the online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database. The Legally Responsible Official will receive an automated CIWQS-issued Notice of Applicability email, confirming continuation of regulatory coverage under this General Order. All regulatory coverage under previous Order 2006-0003-DWQ will cease on the Effective Date of this Order.

An Enrollee continuing existing regulatory coverage is not required to submit a new application package or pay an application fee for enrollment under this General Order.

The annual fee due date for continued regulatory coverage from previous Order 2006-0003-DWQ to this General Order remains unchanged.

A previous Enrollee of Order 2006-0003-DWQ that fails to certify the Continuation of Existing Regulatory Coverage form in the online CIWQS database by the Effective Date of this Order is considered a New Applicant, and will not have regulatory coverage for its sanitary sewer system(s) until:
• A new application package for system(s) enrollment is submitted per section 2.2 (Requirements for New Regulatory Coverage) below; and
• The new application package is approved per section 2.2.2 (Approval of Application Package (For New Applicants Only)).

• Acknowledgement that the existing Enrollee is liable for violations occurring up to the ownership transfer date and that the new Enrollee is liable for violations occurring on and after the ownership transfer date.

The Deputy Director will consider approval of the written request. If approved, the Deputy Director will issue a Notice of Applicability letter which serves as an approved transfer of regulatory coverage to the new Enrollee.

3. FINDINGS

3.1. Legal Authorities

3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160).

3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations.

A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(l)(1)).

Attachment 2

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
8 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to “require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region… or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires…In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports.” Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination.

The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports.

Water Code section 13383(a) authorizes the Water Boards to “establish monitoring, inspection, entry, reporting, and recordkeeping requirements… for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section

5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225(c) and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills Attachment 2

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
9 when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills.

3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general waste discharge requirements than individual waste discharge requirements.

Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system-specific design elements and system-specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements.

As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each Regional Water Board and take into account the environmental characteristics of sewer service areas and hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies.

3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003-DWQ also required system-specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length.

Attachment 2

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
10 To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to:

1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and

2. Implement a proactive approach to reduce spills.

The previous Order required Sewer System Management Plan elements for “the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ with Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.

Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills.

3.1.6. Existing Memorandum of Agreement with California Water Environment Association
The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association’s Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers.

On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Association - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations.

On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators.

ORDER 2022-0103-DWQ December 6, 2022
11 3.2. General

3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States.

3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.

More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage.

Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET)
• Agricultural Supply (AGR)
• Estuarine Habitat (EST)

• Groundwater Recharge (GWR)
• Inland Saline Water Habitat (SAL)

3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state.

There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].

A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to:

Attachment 2

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
13 o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events; o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.

3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses.

Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution.

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

ORDER 2022-0103-DWQ December 6, 2022
14 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste).

3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region-specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives. The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives.

3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings.

The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and (2) enhances the ability for Water Board enforcement of violations of the established prohibitions.

3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.

3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of Attachment 2

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.

3.3.4. State Water Board Human Right to Water Resolution On February 16, 2016, the State Water Board adopted Resolution 2016-0010, titled Adopting the Human Right to Water as a Core Value and Directing its Implementation in Water Board Programs and Activities, addressing the human right to water as a core value and directing Water Board programs to implement requirements to support safe drinking water for all Californians.

On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.

Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.

On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.

This General Order supports the State Water Board priority in collecting a comprehensive set of data for California’s wastewater systems, including sanitary sewer systems. Data reported per the requirements of this Order will be used with data from other Water Boards’ programs, to further develop criteria and create a statewide risk Attachment 2

16 framework to prioritize critical funding and infrastructure investments for California’s most vulnerable populations, including disadvantaged or severely disadvantaged communities with inadequate or failing sanitation systems and threatened access to healthy drinking water supplies.

3.3.5. State Water Board Open Data Resolution
On July 10, 2018, the State Water Board adopted Resolution 2018-0032, titled Adopting Principles of Open Data as a Core Value and Directing Programs and Activities to Implement Strategic Actions to Improve Data Accessibility and Associated Innovation, directing regulatory programs to assure all monitoring and reporting requirements support the State Water Boards’ Open Data Initiative.

3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled Comprehensive Response to Climate Change, requiring a proactive response to climate change in all California Water Board actions, with the intent to embed climate change consideration into all programs and activities.

3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements that is exempt from the California Environmental Quality Act (Public Resources Code section 21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14, section 15301, to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in sections 15301 and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.

3.5. State Water Board Funding Assistance for Compliance with Water Board Water Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation of the State Water Board financial assistance programs, per Board-adopted funding policies. Among other funding areas, the Division administers loan and grant funding for the planning and construction of wastewater and water recycling facilities per funding program-specific policies and guidelines. Applicants may apply for Clean Water State Revolving Fund low-interest loan, Small Community Wastewater grant funding assistance, and other funding available at the time of application, for some of the costs associated with complying with this General Order.
