Agenda Item No. 13
CITY COUNCIL STAFF REPORT
TO: Honorable Mayor and City Council DATE: October 11, 2022 FROM: Matthew Bronson, City Manager
PREPARED BY: Greg Ray, Public Works Director/City Engineer Gabriel Munoz-Morris, Senior Engineer
SUBJECT: Adoption of the 2022 Update to the City’s Sewer System Management Plan
RECOMMENDATION
Adopt the 2022 update to the City’s Sewer System Management Plan.
BACKGROUND
The State Water Resources Control Board’s (SWRCB’s) Statewide General Waste Discharge Requirements (WDR) for Sanitary Sewer Systems require the City of Grover Beach to have and maintain a Sewer System Management Plan (SSMP). The SSMP provides a plan and schedule to properly manage, operate, and maintain all parts of the City’s sanitary sewer system to help reduce and prevent sanitary sewer overflows (SSOs) and mitigate any SSOs that do occur.
Updates to the SSMP must be performed every five years and the City is also required to perform an audit of the SSMP every two years to ensure that all information is correct and that any deficiencies in program components are improved.
Staff contracted Wallace Group to provide an audit of the SSMP in 2021 and update the SSMP for 2022. Adopting this 2022 update to the City’s SSMP will ensure that the City remains in compliance with the SWRCB’s requirements for sanitary sewer systems. This update primarily updates the City’s SSMP by updating staff contact and organizational information while also incorporating required regulatory changes to City operations and procedures since the last SSMP adoption.
FISCAL IMPACT
There is no fiscal impact associated with this action.
ALTERNATIVES
The Council has the following alternatives to consider:
1. Adopt the 2022 update to the City’s Sewer System Management Plan; or
2. Provide staff with alternate direction.
PUBLIC NOTIFICATION
The agenda was posted in accordance with the Brown Act.

2.4 Chain of Communication for Responding to SSOs [WDR D.13(ii)(b)] SSO reports typically begin with a call from an observer to the City of Grover Beach or 911 dispatchers.
City of Grover Beach
Business Hours: (805) 473-4530 8am-5pm Monday through Friday, except City Holidays After Hours: Police Dispatch (805) 473-4511
During the process of responding to a SSO, the following actions are taken as outlined in Figure 3-1 and described below to verify the report and ensure the safety of the public:
1. During business hours, the City Public Works Department receives the call from an observer, the Police Department or the Fire Department and obtains the location of concern and a description of the problem. The name and phone number of the caller is requested and documented if not anonymous for follow-up information.

for use by City maintenance staff to track O&M activities and as a record on the status of sewer and storm drain assets.
4.3 Preventative Maintenance Program [WDR D.13(iv)(b)]
All routine preventative O&M and repair work is managed by the Public Works Supervisor.
Maintenance Staff are comprised of ten (10) full time maintenance workers whose time is split between storm water, water distribution, utility work, streets operations. parks maintenance, fleet maintenance, facilities maintenance and sewer operations and maintenance. These staff members are responsible for operating the sewer collection and conveyance system and performing routine preventative O&M and repair work.
As discussed above; City Public Works staff are responsible for systems other than wastewater collection. The City’s routine preventative O&M plan extends beyond the wastewater collection system. The O&M procedures outlined in this section are a summary of the City’s wastewaterrelated O&M Program. A summary of Routine Preventative Operations & Maintenance includes, but is not limited to, the following:
4.3.1. CCTV Inspection
The City is planning to complete contracted CCTV investigations of the entire system. The City has completed CCTV investigations for approximately half of the system (South) and anticipates completing the second half (North) of by June 2022. This information will be one of the primary methods to identify future sewer line rehabilitation and replacement projects in the future.
When these CCTV investigations are complete, they will be analyzed to; identify, rank and prioritize areas of the sewer system that require rehabilitation and replacement. A summary of these CCTV investigations will be included in Appendix 4-B when completed in August/September 2022.
4.3.2 Routine Line Cleaning
The City will be cleaning the Northern section of the system to facilitate the second half of CCTV investigations described above.
The City’s typical schedule for cleaning sewer lines has consisted of High Maintenance Areas or “Hot Spots” which are cleaned bi-annually. The City will be re-evaluating the frequency at which the entire system is cleaned based on the results of contracted CCTV investigations described above. The City will complete an analysis of this data and based on the results, develop a new schedule for system wide sewer cleaning which will be included in in Appendix 4-B when complete.
4.3.3 Manhole Inspection
City Manholes are inspected in conjunction with sewer line cleaning and CCTV activities. The City utilizes the Sewer Line Cleaning and Manhole Inspection Form for routine documentation of manhole conditions. When significant issues are observed during these routine manhole inspections, a more detailed inspection and assessment is requested by maintenance staff to the City Engineering Department. Relevant information from these sheets is planned to be incorporated into the City’s work history system. An example of the City Detailed Manhole Sewer System Management Plan – Revision 04
Element 4 – Operation and Maintenance Program
City of Grover Beach

Inspection Form is located in Appendix 4-C. Applicable information from these inspections is planned to be utilized in the future development of City rehabilitation and replacement projects.
The advent of the asset management system will alter this process and an update will be provided once a new system is in place.
4.3.4 High Maintenance Areas
The City identifies High Maintenance Areas (HMAs) through CCTV and Line Cleaning observations. HMAs are added to the City’s HMA list as they are identified. The current list of approximately twenty three (23) HMAs can be found in Appendix 4-D. City maintenance staff cleans HMAs semi-annually or more frequently based on observed conditions in the field or customer complaints. HMA inspection and cleaning results are documented on the Sewer Line Cleaning and Routine Manhole Inspection Log also located in Appendix 4-D. The advent of the asset management system will alter this process and an update will be provided once a new system is in place.
4.3.5 Lift Station Operation and Maintenance
As previously referenced in the introduction to this SSMP Element, there are three (3) lift stations located in the City's service area. These stations are provided with a minimum of duplex pumping systems for redundancy and reliability.

ELEMENT 6 - OVERFLOW EMERGENCY RESPONSE PLAN
Sanitary Sewer Overflows (SSOs), or spills, can occur due to unforeseen accidents, unusual equipment failures, or other events not controllable by the City of Grover Beach. A SSO response plan is maintained by the City Public Works Department for City maintenance personnel to use as guidance in responding to SSOs. The SSO response plan defines procedures to:
▪ protect public health and the environment
▪ comply with local, state, and federal regulatory agency requirements ▪ provide appropriate customer service
▪ protect City personnel, the wastewater collection system, and private and public properties
The Overflow Emergency Response Plan (OERP) is summarized in this SSMP Element. The City is in the process of developing emergency response procedures to address issues such as SSO response, detection, mitigation, clean up, investigation, documentation, and reporting which are discussed later in this section. These procedures are planned for completion by December 2022. SSO response is documented using the City’s SSO Field Checklist and associated attachments located in Appendix 6-A.
6.1 Regulatory Requirements
WDR Order No. 2006-0003-DWQ Section D.13 (vi) states:
Each Enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, the plan must include the following:
(a).Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;
(b).A program to ensure appropriate response to all overflows; (c). Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification; (d).Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the OERP and are appropriately trained;
(e).Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and
(f). A program to ensure that all reasonable steps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment Sewer System Management Plan – Revision 04

City of Grover Beach
September 2022
ELEMENT 7 – FATS, OILS, AND GREASE (FOG) CONTROL PROGRAM The City of Grover Beach developed a FOG Control Program in July 2007 establishing the legal authority and programmatic requirements necessary to help eliminate sources of FOG in the City’s sewer collection and conveyance system.
There are approximately sixty (60) food service establishments (FSEs) within the City service area. The types of FSEs are graphically portrayed below in Figure 7-1. The City has an active FOG control and inspection program. To date, facilities enrolled in the FOG Program are permitted and inspected twice a year as FOG has been identified as a potential cause of Sanitary Sewer Overflows (SSOs) and maintenance issues.
The metrics that the City uses to monitor the effectiveness of the FOG Control Program are presented in Element 9 – Monitoring, Measurement, and Program Modifications.
The primary goal of the City of Grover Beach’s FOG Control Program is to decrease the amount of FOG entering the sanitary sewer system to minimize the risk of SSOs.

Element 7 – Fats, Oils and Grease Control Program
City of Grover Beach
September 2022
7.1 Regulatory Requirements
WDR Order No. 2006-0003-DWQ Section D.13(vii) states:
Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification as to why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:
(a).An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG;
(b).A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;
(c). The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;
(d).Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e).Authority to inspect grease producing facilities, enforcement authorities, and whether the Agency has sufficient staff to inspect and enforce the FOG ordinance; (f). An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and (g).Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.
7.2 FOG Control Program Public Education and Outreach [WDR D.13(vii)(a)]
7.1.1 FSE Education and Outreach
The City of Grover Beach recognizes that FOG is an ongoing challenge as a source of sewer system backups and SSOs. The City’s FOG Control Program is designed to prevent SSOs caused by FOG. Outreach and Education efforts are conducted through the following FOG Control information sources:
Residential Outreach and Education
• Flyers with residential FOG information at City Administrative Buildings • Door Hangers to notify residential sewer users when FOG is encountered during sewer line cleaning
Sewer System Management Plan – Revision 04
Element 7 – Fats, Oils and Grease Control Program
City of Grover Beach
September 2022
Commercial Outreach and Education
• Issuance of FSE outreach materials, discharge permits and best management practices for FSEs
• Physical FSE inspections two times per year with follow up inspections for facilities demonstrating compliance issues.
Examples of these Outreach and Education materials are included in Appendix 7A.
7.1.2 FOG Control Program
As discussed earlier Grover Beach developed a FOG Control Program in July 2007 establishing the legal authority and programmatic requirements necessary to help eliminate sources of FOG in the City’s sewer collection and conveyance system.
Formal Inspections permitting is implemented for each FSE. The City inspects each site identified on the City of Grover Beach FSE List located in Appendix 7-A twice a year. Enrollment in the City’s program requires a standard FOG Permit application and FOG Discharge Permit to be issued to all FSEs that have the potential to discharge FOG into the sewer system. A Variance Permit is issued to FSEs that have kitchen facilities but do not currently produce FOG in quantities that may impact the City’s sewer system. FSEs with a Variance Permit will be inspected once a year to verify the facility and/or menu has not changed enough to require a standard FOG Permit and Grease Control Device. FOG Discharge Permits require FSEs to follow all Best Management Practices (BMPs), maintain and operate a Grease Control Device and maintain a cleaning log on the premises. A review of the cleaning log and maintenance information is conducted during each inspection.
In cases where a facility does not currently maintain a grease trap or interceptor, installation is required. Installation will be based upon current Uniform Plumbing Code (UPC) and the City’s Municipal Code. The current UPC is utilized to determine the type and size of unit that will be required. Justification for trap versus interceptor installation will be based upon foods served and prepared, number of drains found within the facility, size and history of the establishment.
Dye testing may also be conducted when it is necessary to determine specific drainage.
During routine site visits inspectors provided the FSE owner with a:
• FOG Control Program Flyer;
• FOG Best Management Practices (BMP) Booklet;
• Grease Hauler List;
• Cleaning Record Form;
• Copy of Inspection Report.
FOG Permits are non-transferrable and are re-issued every three years. FSE compliance is tracked, and FSEs are given a specific number of days to correct violations identified during inspections. Re-inspections occur for all FSEs found to be out of compliance with the City’s FOG Control Program until violations of the City’s program are corrected.
7.3 FOG Disposal Facilities [WDR D.13(vii)(b)]
The City does not own or operate a FOG disposal facility. Licensed FOG hauling contractors are available for the Grover Beach area and are required to dispose of grease to a certified disposal Sewer System Management Plan – Revision 04
Element 7 – Fats, Oils and Grease Control Program
City of Grover Beach
September 2022
facility. The frequency of cleaning for a FSE’s grease control device will be on a case by case basis and therefore a schedule for FOG disposal will also be on a case by case basis.
A list of FOG pumping and/or FOG waste hauling contractors in San Luis Obispo, Santa Barbara and Monterey Counties is provided in Appendix 7A.
7.4 Discharge Prohibition Legal Authority and SSO Prevention Measures [WDR D.13(vii)(c)]
The legal authority to prohibit discharges to the collection system and identify measures to prevent FOG-caused SSOs is found in the City’s Municipal Code.
For reference, Element 3 Legal Authority contains additional information and web addresses for this Municipal Code.

Element 8 – System Evaluation and Capacity District Assurance Plan City of Grover Beach
September 2022
ELEMENT 8 - SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN
8.1 Regulatory Requirements
WDR Order No. 2006-0003-DWQ Section D.13(viii) states:
The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
(a).Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape the system) associated with conditions similar to those causing overflow events, estimates of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events;
(b).Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and (c). Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP may include an implementation schedule and may identify sources of funding.
(d).Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule may be reviewed and updated consistent with the SSMP requirements as described in [WDR Order 2006-0003-DWQ] Section D.14.
8.2 System Evaluation [WDR D.13(viii)(a)]
The City completed a 2019 Sewer Master Plan (SMP) which evaluated both physical and hydraulic conditions for assets in the sewer collection and conveyance system. Hydraulic evaluations were conducted to model existing dry weather conditions and future dry weather conditions which represent “worst case scenario” flow conditions. The study identified conditions that were capacity deficient in 2018 and projected areas shown to be capacity deficient in 2050 at which time it was assumed the City would be at or near build out.
There were no wet weather evaluations conducted in this analysis. A prior analysis in 2011 conducted by the South San Luis Obispo County Sanitation District (SSLOCSD) determined; This basin has minimal I/I for the majority of storm events and exhibits inflow only during larger storm events. Additional flow monitoring is not warranted at this time. The potential Sewer System Management Plan – Revision 04
Element 8 – System Evaluation and Capacity District Assurance Plan City of Grover Beach

for inflow may be further studied by conducting field investigations to locate manholes in obvious paths of surface flow.
This SMP identified several projects to correct capacity related issues in City sewer lines.

The 2019 Master Plan is available on the City website at:
https://www.grover.org/DocumentCenter/View/10423/City-of-Grover-Beach-SMP-ReportFinal?bidId= .
The City is planning on completing a system wide CCTV investigation in 2022 which may provide additional information regarding areas of the collection system subject to hydraulic deficiencies. Based on City staff observations and the findings of the 2019 SMP, any areas found to be hydraulically deficient have not resulted in any SSOs in dry or wet weather since 2007.
Sewer System Management Plan – Revision 04
Element 8 – System Evaluation and Capacity District Assurance Plan City of Grover Beach
September 2022
If dry or wet weather capacity related conditions are observed or SSOs are encountered in the future, the City Public Works Director/City Engineer will assess the need for; future rehabilitation projects, flow monitoring, or an update to the 2019 Master Plan.
8.3 Capacity Enhancement Measures and Design Criteria [WDR D.13(viii)(b)] As stated above, the City based the Capital Improvement Projects (CIP) in the 2019 Master Plan on the following design criteria:
o Design criteria used in this report are: Gravity sewers 8" and below we consider at capacity when the d/D is 50% or less. For 10" and above are considered capacity at 75% d/D.
o The current Standards and Specifications for the City of Grover Beach require new developments be designed to handle an average flow of 100 gallons per person per day. Pipes are to be sized to carry double this amount when flowing half full. Recommended slopes are provided so that a velocity of 2 feet per second is achieved when sewers are half full. Minimum acceptable slopes are also given. Minimum diameters of 8 inches are specified, except on short lines where no possibility of extension exists.
8.4 Schedule [WDR D.13(viii)(d)]
All the capacity related projects identified in the 2019 SMP are listed in Table 8.1. The status/schedule for these projects are also identified in this table. These projects are anticipated to address capacity related issues that may contribute to SSOs in the future.
If conditions occur and are noted through staff’s routine observations, data from 2022 CCTV reports or in the event of a SSO determined to be caused by a new hydraulic constraint, the City Public Works Director/City Engineer will take additional steps such as sewer flow monitoring or update to the 2019 SMP to determine the cause and corrective actions necessary to restore or upgrade system hydraulic capacity.

Element 11 – Communication Program
City of Grover Beach
September 2022
ELEMENT 11 - COMMUNICATION PROGRAM
Communicating the objectives of the SSMP and the importance of sanitary sewer system management practices to the public is essential. An informed public can assist and support the City by reducing customer caused blockages, which will potentially decrease SSOs.
11.1 Regulatory Requirements
WDR Order No. 2006-0003-DWQ Section D.13(xi) states:
The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented.
The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee’s sanitary sewer system.
11.2 Communication Program [WDR D.13(xi)]
The purpose of the City sanitary sewer system communication program is to educate stakeholders, which include residential, commercial, industrial, and satellite users of the collection system, about the SSMP.

Amended Monitoring and Reporting Program (MRP) Order No. WQ 2013-0058-EXEC 0B SSMP Adoption Documents (PLACEHOLDER)
STATE WATER RESOURCES CONTROL BOARD
ORDER NO. 2006-0003-DWQ
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS
FOR
SANITARY SEWER SYSTEMS
The State Water Resources Control Board, hereinafter referred to as “State Water Board”, finds that:
1. All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to comply with the terms of this Order. Such entities are hereinafter referred to as “Enrollees”.
2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of domestic wastewater, as well as industrial and commercial wastewater, depending on the pattern of land uses in the area served by the sanitary sewer system. SSOs often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. SSOs may cause a public nuisance, particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. SSOs may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters.
3. 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. 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.
4. Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age and construction material failures, lack of proper operation and maintenance, insufficient capacity and contractorcaused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures and operation and maintenance of the sanitary sewer system.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 2 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06
SEWER SYSTEM MANAGEMENT PLANS
5. To facilitate proper funding and management of sanitary sewer systems, each Enrollee must develop and implement a system-specific Sewer System Management Plan (SSMP). To be effective, SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, an SSMP must contain a spill response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions.
6. Many local public agencies in California have already developed SSMPs and implemented measures to reduce SSOs. These entities can build upon their existing efforts to establish a comprehensive SSMP consistent with this Order.
Others, however, still require technical assistance and, in some cases, funding to improve sanitary sewer system operation and maintenance in order to reduce SSOs.
7. SSMP certification by technically qualified and experienced persons can provide a useful and cost-effective means for ensuring that SSMPs are developed and implemented appropriately.
8. It is the State Water Board’s intent to gather additional information on the causes and sources of SSOs to augment existing information and to determine the full extent of SSOs and consequent public health and/or environmental impacts occurring in the State.
9. Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No. 2006-0003-DWQ, are necessary to assure compliance with these waste discharge requirements (WDRs).
10. Information regarding SSOs must be provided to Regional Water Boards and other regulatory agencies in a timely manner and be made available to the public in a complete, concise, and timely fashion.
11. Some Regional Water Boards have issued WDRs or WDRs that serve as National Pollution Discharge Elimination System (NPDES) permits to sanitary sewer system owners/operators within their jurisdictions. This Order establishes minimum requirements to prevent SSOs. Although it is the State Water Board’s intent that this Order be the primary regulatory mechanism for sanitary sewer systems statewide, Regional Water Boards may issue more stringent or more State Water Resources Control Board Order No. 2006-0003-DWQ Page 3 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of a Regional Water Board’s WDRs for a system subject to this Order, the Regional Water Board shall coordinate its requirements with stated requirements within this Order, to identify requirements that are more stringent, to remove requirements that are less stringent than this Order, and to provide consistency in reporting.
REGULATORY CONSIDERATIONS
12. California Water Code section 13263 provides that the State Water Board may prescribe general WDRs for a category of discharges if the State Water Board finds or determines that:
x The discharges are produced by the same or similar operations; x The discharges involve the same or similar types of waste; x The discharges require the same or similar treatment standards; and x The discharges are more appropriately regulated under general discharge requirements than individual discharge requirements.
This Order establishes requirements for a class of operations, facilities, and discharges that are similar throughout the state.
13. The issuance of general WDRs to the Enrollees will:
a) Reduce the administrative burden of issuing individual WDRs to each Enrollee;
b) Provide for a unified statewide approach for the reporting and database tracking of SSOs;
c) Establish consistent and uniform requirements for SSMP development and implementation;
d) Provide statewide consistency in reporting; and
e) Facilitate consistent enforcement for violations.
14. The beneficial uses of surface waters that can be impaired by SSOs include, but are not limited to, aquatic life, drinking water supply, body contact and noncontact recreation, and aesthetics. The beneficial uses of ground water that can be impaired include, but are not limited to, drinking water and agricultural supply.
Surface and ground waters throughout the state support these uses to varying degrees.
15. The implementation of requirements set forth in this Order will ensure 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 region and take into account the environmental characteristics of 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 State Water Resources Control Board Order No. 2006-0003-DWQ Page 4 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 water quality in the area, costs associated with compliance with these requirements, the need for developing housing within California, and the need to develop and use recycled water.
16. The Federal Clean Water Act largely prohibits any discharge of pollutants from a point source to waters of the United States except as authorized under an NPDES permit. In general, any point source discharge of sewage effluent to waters of the United States must comply with technology-based, secondary treatment standards, at a minimum, and any more stringent requirements necessary to meet applicable water quality standards and other requirements.
Hence, the unpermitted discharge of wastewater from a sanitary sewer system to waters of the United States is illegal under the Clean Water Act. In addition, many Basin Plans adopted by the Regional Water Boards contain discharge prohibitions that apply to the discharge of untreated or partially treated wastewater. Finally, the California Water Code generally prohibits the discharge of waste to land prior to the filing of any required report of waste discharge and the subsequent issuance of either WDRs or a waiver of WDRs.
17. California Water Code section 13263 requires a water board to, after any necessary hearing, prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. The requirements shall, among other things, take into consideration the need to prevent nuisance.
18. California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
19. This Order is consistent with State Water Board Resolution No. 68-16 (Statement of Policy with Respect to Maintaining High Quality of Waters in California) in that the Order imposes conditions to prevent impacts to water quality, does not allow the degradation of water quality, will not unreasonably affect beneficial uses of water, and will not result in water quality less than prescribed in State Water Board or Regional Water Board plans and policies.
20. The action to adopt this General Order is exempt from the California Environmental Quality Act (Public Resources Code §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., tit. 14, §15308). In addition, the action to adopt State Water Resources Control Board Order No. 2006-0003-DWQ Page 5 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in Section 15301, and §15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
21. The Fact Sheet, which is incorporated by reference in the Order, contains supplemental information that was also considered in establishing these requirements.
22. The State Water Board has notified all affected public agencies and all known interested persons of the intent to prescribe general WDRs that require Enrollees to develop SSMPs and to report all SSOs.
23. The State Water Board conducted a public hearing on February 8, 2006, to receive oral and written comments on the draft order. The State Water Board received and considered, at its May 2, 2006, meeting, additional public comments on substantial changes made to the proposed general WDRs following the February 8, 2006, public hearing. The State Water Board has considered all comments pertaining to the proposed general WDRs.
IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the Enrollees, their agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the California Water Code and regulations adopted hereunder, shall comply with the following:
A. DEFINITIONS
1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include:
(i) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States;
(ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and
(iii) Wastewater backups into buildings and on private property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system.
2. Sanitary sewer system – Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility.
Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 6 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 For purposes of this Order, sanitary sewer systems include only those systems owned by public agencies that are comprised of more than one mile of pipes or sewer lines.
3. Enrollee - A federal or state agency, municipality, county, district, and other public entity that owns or operates a sanitary sewer system, as defined in the general WDRs, and that has submitted a complete and approved application for coverage under this Order.
4. SSO Reporting System – Online spill reporting system that is hosted, controlled, and maintained by the State Water Board. The web address for this site is http://ciwqs.waterboards.ca.gov. This online database is maintained on a secure site and is controlled by unique usernames and passwords.
5. Untreated or partially treated wastewater – Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks.
6. Satellite collection system – The portion, if any, of a sanitary sewer system owned or operated by a different public agency than the agency that owns and operates the wastewater treatment facility to which the sanitary sewer system is tributary.
7. Nuisance - California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
B. APPLICATION REQUIREMENTS
1. Deadlines for Application – All public agencies that currently own or operate sanitary sewer systems within the State of California must apply for coverage under the general WDRs within six (6) months of the date of adoption of the general WDRs. Additionally, public agencies that acquire or assume responsibility for operating sanitary sewer systems after the date of adoption of this Order must apply for coverage under the general WDRs at least three (3) months prior to operation of those facilities.
2. Applications under the general WDRs – In order to apply for coverage pursuant to the general WDRs, a legally authorized representative for each agency must submit a complete application package. Within sixty (60) days of adoption of the general WDRs, State Water Board staff will send specific instructions on how to State Water Resources Control Board Order No. 2006-0003-DWQ Page 7 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 apply for coverage under the general WDRs to all known public agencies that own sanitary sewer systems. Agencies that do not receive notice may obtain applications and instructions online on the Water Board’s website.
3. Coverage under the general WDRs – Permit coverage will be in effect once a complete application package has been submitted and approved by the State Water Board’s Division of Water Quality.
C. PROHIBITIONS
1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited.
2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited.
D. PROVISIONS
1. The Enrollee must comply with all conditions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action.
2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be:
(i) Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order or Consent Decree;
(ii) Interpreted or applied to authorize an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code;
(iii) Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for a sanitary sewer system, authorized under the Clean Water Act or California Water Code; or
(iv) Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board.
3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO.
4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains into State Water Resources Control Board Order No. 2006-0003-DWQ Page 8 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains.
5. All SSOs must be reported in accordance with Section G of the general WDRs.
6. In any enforcement action, the State and/or Regional Water Boards will consider the appropriate factors under the duly adopted State Water Board Enforcement Policy. And, consistent with the Enforcement Policy, the State and/or Regional Water Boards must consider the Enrollee’s efforts to contain, control, and mitigate SSOs when considering the California Water Code Section 13327 factors. In assessing these factors, the State and/or Regional Water Boards will also consider whether:
(i) The Enrollee has complied with the requirements of this Order, including requirements for reporting and developing and implementing a SSMP; (ii) The Enrollee can identify the cause or likely cause of the discharge event; (iii) There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in the capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems.
(iv) The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee;
(v) The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for:
x Proper management, operation and maintenance;
x Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, infiltration and inflow (I/I), etc.);
x Preventive maintenance (including cleaning and fats, oils, and grease (FOG) control);
x Installation of adequate backup equipment; and
x Inflow and infiltration prevention and control to the extent practicable.
(vi) The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 9 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) The Enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible.
7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps and necessary remedial actions to 1) control or limit the volume of untreated or partially treated wastewater discharged, 2) terminate the discharge, and 3) recover as much of the wastewater discharged as possible for proper disposal, including any wash down water.
The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan, including the following:
(i) Interception and rerouting of untreated or partially treated wastewater flows around the wastewater line failure;
(ii) Vacuum truck recovery of sanitary sewer overflows and wash down water;
(iii) Cleanup of debris at the overflow site;
(iv) System modifications to prevent another SSO at the same location; (v) Adequate sampling to determine the nature and impact of the release; and
(vi) Adequate public notification to protect the public from exposure to the SSO.
8. The Enrollee shall properly, manage, operate, and maintain all parts of the sanitary sewer system owned or operated by the Enrollee, and shall ensure that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities.
9. The Enrollee shall allocate adequate resources for the operation, maintenance, and repair of its sanitary sewer system, by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenues and expenditures. These procedures must be in compliance with applicable laws and regulations and comply with generally acceptable accounting practices.
10. The Enrollee shall provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the Enrollee’s System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system owned or operated by the Enrollee.
11. The Enrollee shall develop and implement a written Sewer System Management Plan (SSMP) and make it available to the State and/or Regional Water Board upon request. A copy of this document must be publicly available at the Enrollee’s office and/or available on the Internet. This SSMP must be approved by the Enrollee’s governing board at a public meeting.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 10 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06
12. In accordance with the California Business and Professions Code sections 6735, 7835, and 7835.1, all engineering and geologic evaluations and judgments shall be performed by or under the direction of registered professionals competent and proficient in the fields pertinent to the required activities. Specific elements of the SSMP that require professional evaluation and judgments shall be prepared by or under the direction of appropriately qualified professionals, and shall bear the professional(s)’ signature and stamp.
13. The mandatory elements of the SSMP are specified below. However, if the Enrollee believes that any element of this section is not appropriate or applicable to the Enrollee’s sanitary sewer system, the SSMP program does not need to address that element. The Enrollee must justify why that element is not applicable. The SSMP must be approved by the deadlines listed in the SSMP Time Schedule below.
Sewer System Management Plan (SSMP)
(i) Goal: The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system.
This will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur.
(ii) Organization: The SSMP must identify:
(a) The name of the responsible or authorized representative as described in Section J of this Order.
(b) The names and telephone numbers for management,
administrative, and maintenance positions responsible for implementing specific measures in the SSMP program. The SSMP must identify lines of authority through an organization chart or similar document with a narrative explanation; and
(c) The chain of communication for reporting SSOs, from receipt of a complaint or other information, including the person responsible for reporting SSOs to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services (OES)).
(iii) Legal Authority: Each Enrollee must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to:
(a) Prevent illicit discharges into its sanitary sewer system (examples may include I/I, stormwater, chemical dumping, unauthorized debris and cut roots, etc.);
State Water Resources Control Board Order No. 2006-0003-DWQ Page 11 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (b) Require that sewers and connections be properly designed and constructed;
(c) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency;
(d) Limit the discharge of fats, oils, and grease and other debris that may cause blockages, and
(e) Enforce any violation of its sewer ordinances.
(iv) Operation and Maintenance Program. The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee’s system:
(a) Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities;
(b) Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders;
(c) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and longterm rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the
condition of sewer pipes and scheduling rehabilitation.
Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan;
(d) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and

(v) Design and Performance Provisions:
(a) Design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and
(b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for
rehabilitation and repair projects.
(vi) Overflow Emergency Response Plan - Each Enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, this plan must include the following:
(a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner; (b) A program to ensure an appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification;
(d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained;
(e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 13 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) FOG Control Program: Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:
(a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG;
(b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;
(c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;
(d) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements;
(e) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance;
(f) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and
(g) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.
(viii) System Evaluation and Capacity Assurance Plan: The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
(a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs State Water Resources Control Board Order No. 2006-0003-DWQ Page 14 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events; (b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and
(c) Capacity Enhancement Measures: The steps needed to
establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. (d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update
requirements as described in Section D. 14.
(ix) Monitoring, Measurement, and Program Modifications: The Enrollee shall:
(a) Maintain relevant information that can be used to
establish and prioritize appropriate SSMP activities;
(b) Monitor the implementation and, where appropriate,
measure the effectiveness of each element of the
SSMP;
(c) Assess the success of the preventative maintenance
program;
(d) Update program elements, as appropriate, based on
monitoring or performance evaluations; and
(e) Identify and illustrate SSO trends, including:
frequency, location, and volume.
(x) SSMP Program Audits - As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the State Water Resources Control Board Order No. 2006-0003-DWQ Page 15 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 Enrollee’s compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them.
(xi) Communication Program – The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented.
The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee’s sanitary sewer system.
14. Both the SSMP and the Enrollee’s program to implement the SSMP must be certified by the Enrollee to be in compliance with the requirements set forth above and must be presented to the Enrollee’s governing board for approval at a public meeting. The Enrollee shall certify that the SSMP, and subparts thereof, are in compliance with the general WDRs within the time frames identified in the time schedule provided in subsection D.15, below.
In order to complete this certification, the Enrollee’s authorized representative must complete the certification portion in the Online SSO Database Questionnaire by checking the appropriate milestone box, printing and signing the automated form, and sending the form to:
State Water Resources Control Board
Division of Water Quality
Attn: SSO Program Manager
P.O. Box 100

ORDER NO. WQ 2013-0058-EXEC
AMENDING MONITORING AND REPORTING PROGRAM
FOR
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR
SANITARY SEWER SYSTEMS
The State of California, Water Resources Control Board (hereafter State Water Board) finds:
1. The State Water Board is authorized to prescribe statewide general Waste Discharge Requirements (WDRs) for categories of discharges that involve the same or similar operations and the same or similar types of waste pursuant to Water Code section 13263(i).
2. Water Code section 13193 et seq. requires the Regional Water Quality Control Boards (Regional Water Boards) and the State Water Board (collectively, the Water Boards) to gather Sanitary Sewer Overflow (SSO) information and make this information available to the public, including but not limited to, SSO cause, estimated volume, location, date, time, duration, whether or not the SSO reached or may have reached waters of the state, response and corrective action taken, and an enrollee's contact information for each SSO event. An enrollee is defined as the public entity having leg a! authority over the operation and maintenance of, or capital improvements to, a sanitary sewer system greater than one mile in length.
3. Water Code section 13271, et seq. requires notification to the California Office of Emergency Services (Cal OES), formerly the California Emergency Management Agency, for certain unauthorized discharges, including SSOs.
4. On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ, "Statewide Waste Discharge Requirements for Sanitary Sewer Systems"1 (hereafter SSS WDRs) to comply with Water Code section 13193 and to establish the framework for the statewide SSO Reduction Program.
5. Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP) provide that the Executive Director may modify the terms of the MRP at any time.
6. On February 20, 2008, the State Water Board Executive Director adopted a revised MRP for the SSS WDRs to rectify early notification deficiencies and ensure that first responders are notified in a timely manner of SSOs discharged into waters of the state.
7. When notified of an SSO that reaches a drainage channel or surface water of the state, Cal OES, pursuant to Water Code section 13271 (a)(3), forwards the SSO notification information2 to local government agencies and first responders including local public health officials and the applicable Regional Water Board. Receipt of notifications for a single SSO event from both the SSO reporter 1 Available for download at:
http://www.waterboards.ca.gov/board decisions/adopted orders/water guality/2006/wgo/wgo2006 0003.pdf 2 Cal OES Hazardous Materials Spill Reports available Online at:
http://w3.calema.ca.gov/operational/malhaz.nsf/$defaultview and http://w3.calema.ca.gov/operational/malhaz.nsf Monitoring and Reporting Program Order No. WQ 2013-0058-EXEC Statewide Waste Discharge Requirements for Sanitary Sewer Systems
and Cal OES is duplicative. To address this, the SSO notification requirements added by the February 20, 2008 MRP revision are being removed in this MRP revision.
8. In the February 28, 2008 Memorandum of Agreement between the State Water Board and the California Water and Environment Association (CWEA), the State Water Board committed to redesigning the CIWQS3 Online SSO Database to allow "event" based SSO reporting versus the original "location" based reporting. Revisions to this MRP and accompanying changes to the CIWQS Online SSO Database will implement this change by allowing for multiple SSO appearance points to be associated with each SSO event caused by a single asset failure.
9. Based on stakeholder input and Water Board staff experience implementing the SSO Reduction Program, SSO categories have been revised in this MRP. In the prior version of the MRP, SSOs have been categorized as Category 1 or Category 2. This MRP implements changes to SSO categories by adding a Category 3 SSO type. This change will improve data management to further assist Water Board staff with evaluation of high threat and low threat SSOs by placing them in unique categories (i.e., Category 1 and Category 3, respectively). This change will also assist enrollees in identifying SSOs that require Cal OES notification.
10. Based on over six years of implementation of the SSS WDRs, the State Water Board concludes that the February 20, 2008 MRP must be updated to better advance the SSO Reduction Program4 objectives, assess compliance, and enforce the requirements of the SSS WDRs.
IT IS HEREBY ORDERED THAT:
Pursuant to the authority delegated by Water Code section 13267{f), Resolution 2002-0104, and Order 2006-0003-DWQ, the MRP for the SSS WDRs (Order 2006-0003-DWQ) is hereby amended as shown in Attachment A and shall be effective on September 9, 2013.

Program
Protect your sanitary sewer system and prevent sewer system overflows, properly collect and dispose of Fats, Oils, and Greases generated at your facility. Required Permitting: All Food Service Establishments are required to be permitted to discharge into the public sanitary sewer system. Contact the City of Grover Beach Public Works Department or the Environmental Compliance Inspectors if you have any questions regarding the program or how to obtain a permit.
Cease the Grease!

On July 1, 2007 the City of
Grover Beach was required by the California State Water Resources Control Board, Waste Discharge Requirement Order2006-0003 to establish and implement a Fats, Oils and Grease Control (FOG) Program. The purpose of the program is to reduce the number of sewer pipe blockages affecting the sanitary sewer system, and to provide educational outreach to Food Service Establishments (FSE) relating to the proper disposal of fats, oils and greases generated on a daily basis. Meat fats Lard Food Scraps Dressing and Sauces Baking Goods Butter and Margarine Shortening Dairy Products What Can FSEs Do? In order to prevent sewer system overflows, you can follow a few inexpensive “Best Management Practices (BMP’s).” 1. Maintain your grease trap and/or interceptor properly and adhering to assigned cleaning frequencies identified in your FOG User Permit.
2. Keep all service records for cleaning/
pumping for three years.
3. Scrape grease and
food scraps into the trash prior to washing.
4. Do not put grease down the garbage disposal. Allow the grease to harden and dispose of it into the trash or dump the liquid grease into an approved grease barrel.
5. Be cautious of chemicals and additives (including
soaps and detergents) that claim to dissolve grease.
6. Contact us with any questions or concerns, we’re
here to help!
Why is this important? Everyday commercial kitchens produce large amounts of FOG. These by-products of cooking are not good for the health of your sanitary sewer system. Over time the fats, oils, and grease begin to adhere to the sides of sewer lines that connect to your establishment or the public sewer itself. Sewer System backups can cause: Public health hazards Public property damage Expensive fines that may result in higher sewer bills.
Sewer backups may result in the closure of the your establishment until conditions are corrected. In order to prevent this , the City of Grover Beach has established a No Fee permitting and educational program to help you meet the new requirements Regulation: Effective July 1, 2007

Regulatory Compliance Schedule and Compliance Summary Recommendations The following sections describe these findings in detail and address future additions and updates the City is required to make to its SSMP. The table provided above is a summary and is not intended to replace the detailed findings and recommendations identified in the SSMP Audit Report.
The Sanitary Sewer System General Waste Discharge Requirements (SSSGWDRs) have been in place since 2006 with requirements for the City to develop and implement a SSMP since 2010. It is the expectation of the State Water Resources Control Board (SWRCB) that public agencies have comprehensive Sewer System Management Plans in place with associated plans and programs being implemented. Based on the fact that these regulatory requirements have been in place for over 10 years, these SSMP Audit Report recommendations should be implemented in an expedited time frame and should be included as updates to the SSMP to ensure compliance with the SSSWDR Orders as soon as possible.
The ongoing regulatory timeline required the City to conduct formal SSMP Updates every 5 years after this date (August 2014 & August 2019). The City completed one formal update in 2013, missing the requirement in 2019. It should be noted that an update occurred in 2018 but the version of this document (Rev 3) was never finalized and certified. The 2018 is currently in Draft format. After the 2021 Audit, the City should address findings and recommendations listed in the Audit Report, consider future plans for sewer operations and management and integrate these into an updated and certified SSMP.
SSMP Audits were required on a two-year interval by August 2 nd (2011, 2013, 2015, 2017,
2019, 2021). Audits were completed in 2011, 2013, & 2017 with the required 2021 Audit to be completed in 2021. The City is required to conduct their next Audit on or before August 2, 2023, for compliance with this regulatory timeline.
It should be noted that the City’s Sewer System Overflow (SSO) history shows a low incidence of SSOs when compared to State and Regional municipalities for Category 1, 2, & 3 SSOs as shown in the tables below. The volume of SSOs for Category 1, 2, & 3 SSOs are also low when compared to the average SSO volume experienced in State and Local Agencies of similar size.
The majority of the City’s SSO history (2010 – 2021) occurred between 2010 & 2018. The City has not reported a SSO since 2018. This can be attributed to the City’s operations and maintenance activities which are focused on minimizing SSO events.

Sewer System Management Plan – Revision 3
Audit Report by Wallace Group
City of Grover Beach
August 2021
4.0 Operation and Maintenance Program [SSSWDR D.13(iv)] SSSWDR D.13(iv) states:
The SSMP must include those sections listed below that are appropriate and applicable to the Enrollee’s system:
(a).Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities;
(b).Describe routine preventive and operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) Program should have a system to document scheduled and conducted activities, such as work orders;
(c). Develop a rehabilitation and replacement plan to identity and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed to the capital improvement plan; (d).Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and (e).Provide equipment and replacement part inventories, including identification of critical replacement parts.
General Finding:
This Element of the SSMP is incomplete and in draft form. As a result, it is difficult to assess the plan the City has for Operations and Maintenance of the system.
Finding: Section D.13(iv)(a): All sewer assets and appurtenances are identified in the collection system map referenced in the 2018 SSMP. A sewer system map was reviewed at the time of the audit. A method for tracking updates to the City’s maps was identified in the SSMP however it was unclear if the City sewer maps receive physical updates or if the current map set is accurate to include areas of the collection system discovered in the field or that may have been upgraded. Storm Water conveyance maps are included in the SSMP and are available for City staff to reference in the event of a SSO. A revision record should be utilized to identify when sewer and storm water assets are added, repaired or upgraded. These maps will provide Sewer System Management Plan – Revision 3

maintenance staff with an easy reference to identify sewer and storm water conveyance facilities that may be impacted by and SSO.
Conclusion: The section above is in substantial compliance with the above requirements. See recommendations section below.
Finding: Section D.13(iv)(b): The 2018 City SSMP summarizes goals and Routine Preventative Operation and Maintenance (O&M) activities in this section. O&M relating to; sewer line cleaning, CCTV inspections, and manhole inspections are performed by City staff and by contractors.
The SSMP discusses a year-round pipeline maintenance program for system wide sewer line cleaning is on an annual basis to be instituted in 2018. Annual sewer line cleaning activities have historically been performed by contract staff. At the time of this audit, there was no evidence that annual cleaning schedule is being conducted. Evidence of a formal schedule and records for annual cleaning was not available. City staff does complete quarterly Hot Spot/High Maintenance Area cleaning utilizing a trailer mounted jetter. Records for these cleaning activities were reviewed during the Audit.
The SSMP states that the City’s three (3) Lift Stations are inspected 5 days a week by City Staff and that pump hours and observed conditions are entered in a lift station log. The SSMP discusses a lift station checklist, scheduled inspections, maintenance for specific components of these stations however there was no schedule or maintenance records presented at the time of the audit.
Future revision to the SSMP should include; a schedule for maintenance, lift station checklist and work order forms in this appendix.
Manholes receive an informal inspection during routine sewer line cleaning. Manhole inspection forms are not generated as a result of these informal manhole inspections. Serious conditions are documented on a City Incident Report for future maintenance or rehabilitation. There were no formal records demonstrating manhole inspections had occurred in the past 2 years at the time of this audit.
A formal schedule and tracking system should be developed for sewer line cleaning and manhole inspections. Manhole inspection forms should be developed in conjunction with routine sewer line cleaning and incorporated into the inspection process to track flow conditions and the physical condition of each manhole. Examples of sewer line cleaning, manhole inspections and maintenance records should be included in the SSMP.
Conclusion: The section above is in marginal compliance with the above requirements. See recommendations section below.
Finding: Section D.13(iv)(c): The 2018 SSMP states that the City plans to perform a complete video survey of the sewer system in 2017/18 which will be the basis for identification of future sewer line rehabilitation and replacement projects. Furthermore, the SSMP states that CCTV information will be analyzed, and the results will be included in 2018/19 with a CIP Plan include in the SSMP in 2019.
Sewer System Management Plan – Revision 3
Audit Report by Wallace Group
City of Grover Beach
August 2021
City records show CCTV was performed on approximately 50% of sewer lines as of July 2021.
Staff reports that this information is pending assessment. A Capital Improvement Plan and schedule was identified in the City’s 2022 Budget/Capital Improvement Plan for sewer rehabilitation and replacement projects forecasted between 2022 and 2026. This plan allocates $6.6 million dollars for sewer lines within the City service area. The City is also planning to allocate $450,000 for three (3) Lift Station rehabilitation projects between 2022 and 2026. It is unclear if these projects are a result of CCTV investigations as a formal summary of CCTV reports or ranking of defects were not available at the time of this audit. Records demonstrating a formal plan and schedule to conduct CCTV inspections and assess sewer line deficiencies were not available for review. This section should be updated to include a CCTV analysis and summary of planned projects identified as a result of identified defects.
The City SSMP references a Sewer Master Plan (SMP) conducted in 2006 as addressing most of the requirements in this section. This Master Plan provides an assessment of the City’s sewer system; lift stations, force mains, manholes, and sewer line (capacities). CCTV inspections were not conducted as part of the 2006 Master Plan. A Capital Improvement Plan organized in three phases was developed based on the results of the Master Plan. City staff reports that these projects were completed prior to 2013.
This section should be updated to document specific projects planned between 2022 and 2026, based on the newer SMP (2019) and updated annually to discuss the status of current and future projects identified by the City.
The City funds capital projects utilizing sewer user fees and existing Enterprise Fund reserves.
Based on a review of the 2022 Budget, it appears the City has a sewer reserve fund for capital improvements. A summary of City funding mechanisms and specific projects should be included in future SSMP revisions and updates.
The SSMP needs to be updated to discuss planned capital projects and funding mechanisms that meet the requirements of this section. A plan and schedule to conduct CCTV inspections and a system for ranking the condition of sewer pipes and scheduling rehabilitation and replacement needs to be developed and included in the SSMP.
Conclusion: The section above is in partial compliance with the above requirements. See recommendations section below.
Finding: Section D.13(iv)(d): The 2018 SSMP states that Staff receives extensive training in system operations and maintenance. Staff reports that training exercises for Lift Station Operations, Overflow Emergency Response Plan, SSO Response/Spill Prevention/Control, Sewer Jetter Training, and Safety. Records reviewed for Staff’s participation in these training sessions were limited at the time of this audit.
Training procedures for collection system operations, maintenance, and monitoring were not available at the time of this audit. Development of SOPs are discussed in the 2018 SSMP, for completion by September 2018. Procedures should be developed for O&M activities that are specific to the City sewer system and training should be conducted annually at a minimum or when conditions require more frequent training. All training should be documented.
Conclusion: The section above is in marginal compliance with the above requirements. See recommendations section below.

Audit Report by Wallace Group
City of Grover Beach
August 2021
Finding: Section D.13(iv)(e): A list of current collection system critical parts and equipment was provided for maintaining City sewer lines, lift stations, and manholes in Appendix 4I of the SSMP.
The City should review the list of critical parts and equipment for all assets and equipment used in the sewer system and attach a vendor and/or contractor list with contact information for parts, equipment and services that are not easily or reasonably stocked or maintained by the City.
Include an updated list in the next update to this SSMP.
Conclusion: The section above is in compliance with the above requirements. See recommendations section below.
Element 4 Sufficiency: Partial Compliance
Reference: 2018 SSMP and Appendices, City Sanitary Sewer Master Plan (SMP): 2006, 2019 SMP, City Critical Parts and Equipment List, City List of Hot Spots, Capital Improvement Budget 2022, 2021 CCTV Data.
Findings: The 2018 SSMP Element 4: Operation and Maintenance Program has the following deficiencies:
▪ This Element of the SSMP is incomplete (in Draft Form) and should be updated. ▪ The preventative maintenance program is not being implemented as described in the SSMP. Annual cleaning and inspection objectives are not being met. There is no formal process to conduct and document regular manhole inspections and line cleaning. ▪ Lift Station O&M activities and preventative maintenance schedules are not presented or documented in the City SSMP.
▪ The CCTV schedule, how the pipeline segments are assessed, and the plan for rehabilitation and/or repair of those pipeline segments have not been implemented as discussed in the SSMP.
▪ Existing and planned sewer capital projects and rehabilitation efforts that meet the requirements of the Rehabilitation & Replacement Program should be referenced and included in the SSMP. If additional projects have been identified or are in the process of being identified they should be described and referenced in the SSMP. ▪ City records do not demonstrate that a formal training program has been developed as described in the SSMP. Future updates should include a training schedule, procedures, and records to demonstrate City staff is receiving formal training on O&M activities specific to City sewer operations.
Recommendation: Deficient sections of the O&M Program to be created and documented in the next SSMP revision include:
Sewer System Management Plan – Revision 3
Audit Report by Wallace Group
City of Grover Beach
August 2021
▪ Create and implement a formal plan and schedule that outlines sewer line cleaning and manhole inspections in routine and high maintenance areas. Create a tracking system and record for these areas as they are maintained. (Records are required to be maintained for 5 years for compliance with the SSSWDR). Include examples of these records in the updated SSMP. Include the work order form and other log and inspection templates included in the 2018 SSMP in the appendix of the updated SSMP. ▪ Utilize the manhole inspection form included in the appendix of the SSMP to conduct formal inspections and include a section on the City Sewer Line Cleaning Log for routine manhole observations.
▪ Develop a formal Rehabilitation and Replacement (R&R) Plan that incorporates CCTV sewer line condition assessments and future manhole inspection data. Create a proposed short- and long-term CIP completion schedule and document in a table which projects were initiated and/or completed. Update this table as additional projects are completed and/or added as a result of future City investigations. Provide a summary of how these projects will be funded.
▪ Sections of the 2006 Sewer Master Plan (SMP) or recent 2019 SMP (not referenced in the 2018 SSMP) that can be used to meet the requirements of the Rehabilitation & Replacement Program should be referenced and included in the SSMP. ▪ Review existing critical parts and equipment list and contacts for the operation and maintenance of City sewer assets and update as applicable. If some parts and equipment are not planned to be stocked by the City, document the vendors for these items and contact information. If equipment is available through mutual aid agreements with neighboring agencies or through contract services, document/reference these agreements in the SSMP. Track quantities of parts and equipment in stock and replace to keep a rolling stock for future use.
▪ Develop training procedures specific to City O&M activities and train on these procedures annually. A sample list of Collection System O&M Procedures attached to the Audit for an idea of potential procedures. The City should provide evidence that contractors are trained for specific O&M activities and Emergency Operations they perform for the City and that they are aware of City collection system procedures.
Maintain documentation of this training.
