CITY OF HEMET 2024 SEWER SYSTEM MANAGEMENT PLAN UPDATE Page 35  Hamilton – Florida to Kimball (330 feet of 8" pipe)
The following CIP projects are currently in progress:
 Under residential homes between Thompson and Franklin on Central  Devonshire/ Kirby/ Latham/Florida (8” pipe)
The following CIP projects are to be completed:
 Residential backyard between Central/Mayberry Harvard/State (599 feet)  Carmarita between Acacia and Central (240 feet of 6” pipe)  Residential easement from Central to Mayberry between Carmalita and Juanita (527 feet of 6” of pipe)
 Buena Vista From Mayberry 305’ southerly (305 feet of 8” pipe)  Taylor – Whittier 295’ northerly (295 feet of 6” pipe)  Griffith Way-330 feet of 6” pipe
 Santa Fe from Florida Ave. to Acacia 1291 8” pipe
In order to address the high priority CIP projects while also addressing more routine projects to prevent them from entering into an advance state of despair, the City’s 2021 Sewer Master Plan Update recommends bifurcating the CIP into priority projects and routine rehabilitation projects. The City utilizes an established rate system to fund ongoing operation and maintenance of the sewer collection system and ongoing CIP for sewer rehabilitation/replacement. The City’s CIP budget is projected to be $1.5 million per year, with $0.75 million per year towards high priority CIP projects, and $0.75 million per year towards routine rehabilitation projects.

Joint coordination is conducted between City operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects. As previously mentioned, the City also has an interagency agreement with EMWD which establishes interagency coordination.

Order No. 2022-0103-DWQ Statewide General Waste Discharge Requirements

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 or performance evaluations; and
 Identifying and illustrating spill trends, including spill frequency, locations, and estimated volumes.

Performance Indicators
The City of Hemet uses the following performance indicators to monitor the implementation of the SSMP elements:

The technical and monitoring reports submitted by the City through CIWQS are used to evaluate and ensure compliance with the SSMP. Pursuant to SWRCB Order No. 2022-0103-DWQ (Attachment E Section 3.7) Electronic reporting of Spill / No Spill reports to the CIWQS are done on a monthly basis.

Data collected for these reports include:
 Number of spills over the past twelve months
 Volume distribution of spills
 Volume of spills that was contained in relation to total volume of the spills  Spills by cause (e.g. roots, grease, debris, pipe failure, other).  Number of blockages over the past 12 months
 Average time to respond to a spill
 List of repair, rehabilitation, and replacement projects  Plans developed for, or implementation of, activities to target specific problems identified, such as roots, structural deficiencies, or fats, oil, grease, and trash Performance Evaluations / Updating Program Elements
The following steps will be taken by the City to assure the SSMP remains current and useful over time:
 The Water/Wastewater Superintendent shall review the SSMP periodically to check effectiveness and timeliness.

18.A

CITY OF HEMET SEWER SYSTEM MANAGEMENT PLAN Page 37
 The Water/Wastewater Superintendent shall check in with collection systems staff at periodic intervals to review the effectiveness and identify potential areas for improvement, either individually or through meetings.
 Internal audits of the SSMP shall be completed every three years to document effectiveness, potential changes, and summarize program activities.
 City Council approval will be obtained to update the SSMP with specific revisions.  The SSMP shall be updated at least every six years following the original adoption date The City reviews its “No Spill” Reports on a regular basis in an ongoing effort to improve the performance of the City’s SSMP. The City reviews the performance of the sanitary sewer system on an annual basis taking into consideration the number of, category, location, and cause of all spills, and the sewer system cleaning/CCTV efforts in its evaluation to determine if any changes to the SSMP are needed.

Each element of the City’s SSMP was developed to complement and support the other elements. As part of the City’s CIP, the SSMP goals are reviewed and updated, as necessary. The deliverables required to meet the SSMP goals are defined and prioritized, lead and support staff and resources are assigned, and progress is measured and reported to ensure the City is meeting or exceeding the SSMP goals and achieving full compliance with the SSMP requirements. Overall SSMP performance is evaluated and reported to City management following the end of each fiscal year.

Any updates necessary to enhance the SSMP performance are identified and integrated as part of the City’s CIP.

The City uses a variety of techniques to measure the effectiveness of its SSMP components. Data is recorded by each crew daily. Data recorded in the field is compiled into a database and extracted into weekly, monthly, and yearly reports. Spill data is an important measure of sewer system performance. The frequency, location, and volume of spills is often used to determine how resources will be allocated. Data will also be used to recalibrate the frequency of cleaning activities. Sewer system management is regularly evaluated for effectiveness and when needed, protocols are updated to produce more favorable outcomes. In addition, the City utilizes community outreach via the City’s website.

The City maintains and document relevant information needed to establish and prioritize plan activities. This information is entered into a computerized maintenance management system (Cartegraph /OpenGov Asset Management).

Table 3 provides a summary of the performance indicators for tracking effectiveness relative to each SSMP element.

ELEMENT 10 – INTERNAL AUDITS
Order No. 2022-0103-DWQ Statewide General Waste Discharge Requirements

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 the General Order.

Internal Audit Program Description
The City of Hemet will conduct periodic audits focused on evaluating the effectiveness of the City’s SSMP and the City’s compliance with the provisions of the SWRCB Order No. 2022-0103-DWQ for each of the elements of an SSMP, including identification of any deficiencies in the SSMP and steps to correct them. New information regarding the daily operations of the sewer system, staff names and contact information, equipment and supply inventory can be inserted in the documents at this time. The City will audit the SSMP on intervals not to exceed three years. The SSMP will be modified to reflect any new or updated information. The City will have an audit team primarily consisting of City Staff from the Public Works Department and Water/Wastewater Division that will conduct the audit.

The scope of the audit will cover each of the major sections of the SSMP. An audit checklist, based on the requirements in the SWRCB Order No. 2022-0103-DWQ is included as Appendix C.

Within six months after the end of the required 3-year audit period, the Legally Responsible Official shall submit a complete audit report to the online CIWQS Sanitary Sewer System Database that address the following items:
 Evaluate the implementation and effectiveness of the City’s SSMP in preventing spills;  Evaluate the City’s compliance with this General Order;  Identify SSMP deficiencies in addressing ongoing spills and discharges to waters of the State; and
 Identify necessary modifications to the SSMP to correct deficiencies.

A complete audit report shall include:
 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.

18.A

CITY OF HEMET 2024 SEWER SYSTEM MANAGEMENT PLAN UPDATE Page 41 ELEMENT 11 – COMMUNICATIONS PROGRAM
Order No. 2022-0103-DWQ Statewide General Waste Discharge Requirements

11. COMMUNICATION PROGRAM:

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

The City’s Spill Emergency Response Plan (Appendix F) provides procedures on communication with the public on closures, resulting from spills and discharges.

After completing SSMP program audits discussed in Section 10 of this SSMP, the City’s Public Works and Engineering Departments will communicate the results and propose changes to the SSMP.

The SSMP will be available to the public on the City’s website. The public is invited to comment on the SSMP at any time through the website or by calling the City’s Public Works Department.

The City’s website will be the primary source for public information and input on the SSMP. The website will provide the public the ability to review and comment on the SSMP and the SSMP performance reports, and any updates as needed. The City’s website will also provide a current Sewer Master Plan discussing the City’s CIP requirements.

The City is a subagency of EMWD. EMWD maintains all contact information with all affiliated sewer systems within EMWD’s service area informally through collection system field interactions and/or Source Control needs. Additionally, EMWD’s SSMP is available on EMWD’s website for satellite agencies to be able to download and review. While EMWD is contracted to maintain many of its subagencies’ collection systems, EMWD has an open communication with agencies who maintain and operate their own sewer system facilities within EMWD’s service area (e.g. the City).

The City has a good record when it comes to spills. The number of spills is within limits and zero spills have resulted in community health hazards. Therefore, the Communications Program has been designed with an appropriate level of community involvement.

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.

18.A

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)).

18.A

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

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.

18.A

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)

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:

18.A

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

18.A

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

15 Compliance While Maintaining Water Quality Protection. 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

ORDER 2022-0103-DWQ December 6, 2022
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.

17 Section 13477.6 of the Water Code authorizes the Small Community Grant Fund.

The Small Community Grant Fund allows the State Water Board to provide grant funding assistance to small, disadvantaged communities and small severely disadvantaged communities that may not otherwise be able to afford a loan or similar financing for projects to comply with requirements of this General Order. The State Water Board also considers loan forgiveness on a disadvantaged community-specific basis.

For disadvantaged communities’ wastewater needs, the State Water Board places priority on the funding of projects that address:
• Public health;
• Violations of waste discharge requirements and National Pollutant Discharge Elimination System (NPDES) permits;
• Providing sewer system service to existing septic tank owners; and • High priority public health and water quality concerns identified by a Regional Water Board.

3.6. Notification to Interested Parties
On January 31, 2022, the State Water Board notified interested parties and persons of its intent to reissue Sanitary Sewer Systems General Order 2006-0003-DWQ by issuing a draft General Order for a 60-day public comment period. State Water Board staff conducted extensive stakeholder outreach and encouraged public participation in the adoption process for this General Order. On March 15, 2022, the State Water Board held a public meeting to hear and consider oral public comments. The State Water Board considered all public comments prior to adopting this General Order.

Chapter 1 Introduction
The purpose of the Spill Emergency Response Plan is to minimize the impact of sewer sanitary sewer spills on the public and on the environment. Spill containment and protection of public health shall be the highest priority.

This plan shall be reviewed on a regular basis (at least annually) and shall be updated as needed.

1.1 Regulatory Requirements

1.1.1 Statewide General Waste Discharge Requirements (GWDR) The Statewide GWDR for Sanitary Sewer Systems was adopted by the State Water Resources Control Board of California (SWRCB) on May 2, 2006. On September 9, 2013, SWRCB adopted Order No. WQO 2013-0058-EXEC which amended the Monitoring and Reporting Program issued under SWRCB Order No. 2006-0003-DWQ. The amendment included the addition of a spill Category 3 and revised the spill Category 1 and Category 2 reporting requirements. On December 6, 2022, the State Water Resources Control Board adopted Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems (Order No. 2022-0103-DWQ), which amended the SWRCB General Order 2006-0003-DWQ and 2013-0058-EXEC. The amendment became effective June 5, 2023 and included the addition of a spill Category 4 and revised the spill Category 3.

The goal of the GWDR is to provide a consistent statewide approach for reducing spills. The GWDR requires all publicly owned sanitary sewer collection systems in California with more than one mile of sewer pipe to develop and implement a system-specific Sewer System Management Plan (SSMP).

The SSMP must contain a Spill Emergency Response Plan (SERP) that establishes standard procedures for immediate response to a spill in a manner designed to minimize water quality impacts and potential nuisance conditions. The SERP must include procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Plan and are appropriately trained.

Chapter 3 Response to Notification of Spill

3.1 Public Report of Spills
Public observation is the most common way the City is notified of sewer blockages and spills.

There are several ways the public can report spills:  The local phone book and the City of Hemet website (www.hemetca.gov) have contact information for reporting spills. Telephone the City of Hemet Public Works Department at (951) 765-3712.  An online service request can also be made through https://www.hemetca.gov/1112/How-to-Submit-a-Request . (Link on City of Hemet website)

3.1.1 During Normal Working Hours
The regular working hours for the City of Hemet Wastewater Division are Monday through Thursday, from 6:00 AM to 4:30 PM. When a report of a sewer spill or backup is made, staff in the Public Works administration office determines if the spill is in the City service area. If it is, the call is immediately routed to the Wastewater Superintendent or Wastewater Water Supervisor, who takes information from the caller and dispatches a maintenance crew to the spill/overflow site.

3.1.2 After Normal Working Hours
After working hours, a recorded phone message provides callers with an after-hours emergency response number which connects them to the Hemet Police Dispatch (951) 765-2400. Police dispatch obtains information about the incident and notifies the Public Works On-Call Supervisor. The On-Call Supervisor dispatches a maintenance crew to the site. In the case of a major spill, the On-Call Supervisor may contact the Wastewater Superintendent and/or Wastewater Supervisor, to assist in responding to the incident.

3.2 Staff Observation
City field crews perform periodic work on the sewer collection system. Any problems noticed are reported to the Wastewater Superintendent and/or Wastewater Water Supervisor, who will determine the response if the problem is an emergency situation. Corrections for non-emergency conditions are noted and placed on the maintenance work schedule.

WATER QUALITY MONITORING PROGRAM
Last Revision May 2024
WATER QUALITY MONITORING – KEY ELEMENTS
Trigger for Water Quality Sampling  StateWater Resources Control Board (SWRCB) Sampling must be performed for spills that are 50,000 gallons or greater and reach surface water.  RiversideCounty Departmentof Environmental Health (DEH) Sampling must be performed for spills that reach surface water if County DEH staff indicates that sampling is necessary.

Safety and Access

1. Water quality sampling should only be performed if it is safe to do so and access to the surface water is not restricted. Unsafe conditions include, but are not limited to, heavy rains, slippery and/or steep riverbanks, and visibility issues.

2. When sampling is not possible, details of the situation should be recorded in the certified Category 1 Spill Report and the Spill Technical Report submitted to the CIWQS Online Sanitary Sewer System Database.

When to Sample

1. Sampling must be performed (when and if it is safe to do so) within 18 hours after initial spill notification.

2. Water quality sampling should not interfere with stopping the spill.

Optional Follow-Up Monitoring
It may be appropriate to conduct additional monitoring by sampling and/or visual inspection, depending on the original monitoring results. For example, follow-up monitoring could be conducted until the water body has reverted to an estimated baseline condition if an impact from the spill is observed or if directed by County DEH.

WATER QUALITY SAMPLING PROTOCOLS (SWRCB REQUIREMENTS)
Sampling Parameters required for Analyses:
• Ammonia (labeled “A” on sample bottles)
• Fecal coliform bacteria (labeled “B” on sample bottles) Spill Sample Collection Kit Inventory:

SPILL WATER QUALITY MONITORING PROGRAM
APPENDIX D - CITY OF HEMET SANITARY SEWER OVERFLOW RESPONSE PLAN Page 1 Revised May 2024
92 Page 179 of 261

18.A

Sampling Locations:

1. “Upstream” of spill

2. Immediate vicinity where spill enters water body (“source”)

3. “Downstream” of spill
Sample Collection Procedure

1. Retrieve Spill Sample Collection Kit (cooler) from Water Department office.

2. Determine which analyses are required and retrieve the necessary samples bottles (see Spill Sample Collection Kit Inventory).

3. Obtain ice from freezer & place in cooler.

4. Determine the point where spill entered waterway and, if possible, photograph this location. Try to include a reference point in the photo.

5. If sampling is performed after the spill has stopped, estimate spill travel time. a. This may be done by observing or dropping floatable debris in the surface water and timing how long it takes to travel over a measured distance (e.g., 100 feet).

Include sections in the surface water where there are bends, bottlenecks, or other characteristics that may slow down the flow. If the first measurement is uncertain, this time estimate may be performed three to five times, and the values averaged to determine the estimated travel time. The velocity in the upper portion of the water body can then be calculated by dividing the measured distance by the average time.
b. An alternative way to measure the spill travel time is to use a velocity probe to determine the rate of flow in the water body.

6. Determine the “source” location for water quality sampling by accounting for spill travel time.
a. If the spill is occurring, the “source” location is the point where the spill is entering the waterway.
b. If the spill has stopped, calculate the approximate downstream distance from the original spill location by dividing the time since the spill occurred by the estimated velocity. This is the approximate downstream distance from the spill discharge point to the “source” sampling location.

7. Put on safety gloves and safety glasses from the Spill Sample Collection Kit.

8. For each parameter, label the sample bottles with the location names (e.g., “Upstream”, “Source”, and “Downstream”).

Upstream Sample Collection

1. Collect the upstream samples first.

2. Move approximately one hundred feet (100’) upstream of Source location.

3. Label each of the sample bottles marked “Upstream” with the date and time.

4. (If possible) take a photo of the sample location, including a reference point in the photo.

5. Fill the labeled bottles against the direction of the water flow just below the surface in knee deep water, approximately 3 feet deep (full arm’s length), without rinsing. Fill bottle leaving about 1” of air to allow for mixing. If needed, extend the sampling pole to the fullest length to reach deeper water depth. Avoid sampling debris or surface scum and minimize contact with bank or beach bed as water fouling may occur.

6. Immediately place cap securely on bottle to avoid leaks and contamination. Dry bottle.

7. Place each sample bottle in the cooler after collection.

SPILL WATER QUALITY MONITORING PROGRAM
APPENDIX D - CITY OF HEMET SANITARY SEWER OVERFLOW RESPONSE PLAN Page 2 Revised May 2024

18.A

Source Sample Collection

1. Collect the “source” samples next.

2. Move approximately ten feet (10’) downstream of the Source location.

3. Label each of the sample bottles marked “Source” with the date and time.

4. (If possible) take a photo of the sample location, including a reference point in the photo.

5. Fill the labeled bottles against the direction of the water flow just below the surface in knee deep water, approximately 3 feet deep (full arm’s length), without rinsing. Fill bottle leaving about 1” of air to allow for mixing. If needed, extend the sampling pole to the fullest length to reach deeper water depth. Avoid sampling debris or surface scum and minimize contact with bank or beach bed as water fouling may occur.

6. Immediately place cap securely on bottle to avoid leaks and contamination. Dry bottle.

7. Place each sample bottle in the cooler after collection.

Downstream Sample Collection

1. Lastly, collect the downstream sample.

2. Move one hundred feet (100’) downstream of the
source location.

3. Label each of the sample bottles marked
“Downstream” with the date and time.

4. (If possible) take a photo of the sample location,
including a reference point in the photo.

5. Fill the labeled bottles against the direction of the water flow just below the surface in knee deep water,
approximately 3 feet deep (full arm’s length), without
rinsing. Fill bottle leaving about 1” of air to allow for mixing. If needed, extend the sampling pole to the

SAMPLE COLLECTION BEST PRACTICES
Avoid Contamination—
Make every effort not to touch the inside
of the collection bottle or the inner
surface of the lid or bottle rim.

Deliver Samples to Lab Immediately—
All samples need to be delivered to the
laboratory expeditiously due to the
limited hold time required for
maintaining sample integrity.
fullest length to reach deeper water depth. Avoid sampling debris or surface scum and minimize contact with bank or beach bed as water fouling may occur.

6. Immediately place cap securely on bottle to avoid leaks and contamination. Dry bottle.

7. Place each sample bottle in the cooler after collection.

8. If additional sites are required and specified by County EHD, continue to perform sampling at these additional sites according to sampling procedures in the previous step.

Transporting Samples to Laboratory

1. Complete the laboratory requisition slip with requested information: site, bottle number, collector, date and time of collection, type of sample, analyses requested, name and phone number of responsible person for reporting purposes, and deliverer name.

2. Transport the cooler containing the samples for bacterial analyses & the completed laboratory requisition slip to the laboratory as soon as possible after sample collection. The parameter with the shortest holding time is 8 hours (from sample collection to beginning of analysis), but sample analyses should begin as soon as possible after sample collection because that will achieve the most accurate result. Also, the laboratory needs time to process the samples, before beginning the analyses.

Best Practices for Sanitary Sewer Overflow (SSO) Prevention and Response Plan
The formula used to develop Table Cis Q=CcVA, where Q is equal to the quantity of the flow in gallons per minute, Cc is equal to the coefficient of contraction (.63}, V is equal to the velocity of the overflow, and A is equal to the area of the pick hole.2 If all units are in feet, the quantity will be calculated in cubic feet per second, which when multiplied by 448.8 will give the answer in gallons per minute. (One cubic foot per second is. equal to 448.8 gallons per minute, hence this conversion method).

Example Overflow Estimation:

The maintenance hole cover is in place and the height of water coming out of the pick hole seven-eighths of an inch in diameter (7/8") is 3 inches (3n). This will produce an SSO flow of approximately 4.7 gallons per minute.
