LETTER OF COMPLIANCE

City of Chino
Att: Keith A. Martinez, Public Works Services Manager
Legally Responsible Official (LRO)
Sanitary Sewer Collection System (WDID #8SSO20032)
5050 Schaefer Ave
Chino, CA 91710
Dear Keith,
We are pleased to present the new 2025 Sewer System Management Plan (SSMP) Update developed in partnership with City management. The 2025 Update meets and exceeds compliance with the WDR (State Water Board, Water Quality Order No. 2022-0103-DWQ, Attachment D-10 and Specifications 5.4).

The 2025 SSMP has been completely revised to harmonize with industry standard guidelines and incorporates the City’s latest SSMP Audit findings.

The 2025 SSMP is a declaration of what the City is doing to demonstrate full compliance with the Reissued WDR. Attachment A of the Reissued WDR (page A-4), states “A sewer system management plan is a living document an Enrollee develops and implements to effectively manage its sanitary sewer system(s) in accordance with this General Order. ” As a reminder, the WDR requires the City to review and update the SSMP as necessary until its next 6-year SSMP Update is completed.

To support these ongoing review and update requirements, this document includes a sample change log that may be used as a reference if a system is not already in place. We encourage you to share this example with all relevant team members responsible for implementing or documenting SSMP revisions, to help ensure consistency, transparency, and continued compliance.

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

Sincerely,

James Fischer, P.E.

The City of Chino is a general law city bordered by the Cities of Ontario, Pomona, Chino Hills, Eastvale, and Montclair, (see Figure 1-1 below). The City service area covers approximately 30 square miles serving a population of nearly 95,000, including approximately 23,000 individual sewer service lateral connections for residents and businesses. According to the City’s latest 2022 Sewer Master Plan Update (see Appendix

8.1), the City’s sanitary sewer collection system consists of approximately 271 miles of gravity sewer pipelines ranging from 6-inch to 21-inch in diameter, 0.5 miles of 4-inch diameter force main sewers, 5,000 sewer manholes with 23 individual diversion manholes in place , 4 gravity siphons, and three sanitary sewage lift stations. The City is expecting to acquire one additional sewage lift station currently operated by the Inland Empire Utilities Agency (IEUA) in 2029.

Sewage treatment is provided by IEUA, a regional utility agency that provides sewer treatment services for several municipalities, including the City. There are three regional, IUEA -owned and operated sewer treatment plants in the City of Chino, including Regional Water Recycling Plant No. 2 (RP-2), Regional Water Recycling Plant No. 5 (RP-5), and the Carbon Canyon Water Recycling Facility (Carbon Canyon).

GOAL AND INTRODUCTION

© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 7 of 65 The City currently utilizes ACCELA SERVICE REQUEST electronic computerized maintenance management software (CMMS) for managing and tracking all day-to-day service requests and completed work in the sewer system. Accela allows agencies to organize and manage requests and strengthen citizen relations. By automating service requests and providing a centralized database, Accela ensures City staff can access real- time information about the status of all service requests at any time.

In November 2023, the City established a brand-new program for addressing maintenance of lower sewer laterals to improve sewer system maintenance more proactively and systematically address issues specific to these assets utilizing ACCELA to manage work for this program . This effort includes comprehensive repairs of problem assets throughout the system.

GOAL AND INTRODUCTION

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

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

COMPLIANCE
This SSMP has been completed updated to meet the requirements of Order WQ 2022 -0103-DWQ and address all required Elements and Specifications required by the Order. The SSMP addresses management, operations, and maintenance procedures specific to the City’s collection system. The City maintains a proactive O&M program to operate its system and identify defects, which are then prioritized for repair, replacement, rehabilitation, or placed on modified maintenance schedules. (See Elements 4 and 8 and Specifications 5.19 of this SSMP for more detail).

The City keeps up with current industry standards, technology, and best practices by reviewing industry periodicals, networking, and attending industry/vendor trainings at conferences and workshops. The City continuously evaluates emerging practices, equipment and technologies for possible implementation to enhance its sewer operations, including completing regular California Water Environment Association (CWEA) training events and other trainings held by IEUA with other regional area sewer system operators to help improve emergency response coordination and effectiveness.

GOAL AND INTRODUCTION

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

COMPLIANCE
The City maintains various revenue sources to maintain financial stability, meet its operational needs and manage all necessary expenditures to operate its sewer system.

The City receives two types of funding for its sewer operations. The first source is a Sewer Development Impact Fee (DIF), which is assessed on all expansions of capacity needs resulting from new developments as well as all new construction. These funds are used for system expansion projects and are shown in the Capital Improvement Plans for the Sewer Collection System. The City collects Sewer DIF fees from both projects within the City and projects within the Preserve.

The second funding source is through user fees, which are charges assessed to individual users of the system for operations, maintenance, and repairs. Equivalent Dwelling Units (EDU) establishes these sewer fees. 1 EDU= 270 GPD. The permitted industries sewer fees are calculated based on their EDUs as well as a factor for the Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) measured in their sewer flows.

A list of revenue generated from Chino’s residents, businesses, and industries are included in Appendix 1.1 showing City revenue history by fund.

The City has basic staffing and equipment to properly manage the collection system and continuously evaluates its sewer system resources, and funding needs to stay proactive and prevent spills. As part of this effort, the City will complete a new assessment to review its resources and staffing before its next SSMP Audit is due in 2027.

GOAL AND INTRODUCTION

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

3. Legal Authority

WDR REQUIREMENTS
Att. D-3 (pg. D-4)
“The Plan must include copies or an electronic link to the Enrollee’s current sewer system use ordinances, service agreements and/or other legally binding procedures to demonstrate the Enrollee possesses the necessary legal authority to:
• Prevent illicit discharges into its sanitary sewer system from inflow and infiltration (I&I); unauthorized stormwater; chemical dumping; unauthorized debris; roots; fats, oils, and grease; and trash, including rags and other debris that may cause blockages; • Collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure; • Require that sewer system components and connections be properly designed and constructed; • Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the Enrollee;
• Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures; and
• Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

COMPLIANCE
The above items are addressed below:

The City’s legal authority to own and operate a sanitary sewer system is derived from its incorporation as a City in the year 1910. Pursuant to Government Code Sections 50022.1 -50022.8 and 50022.10, the City of Chino Municipal Code Chapters 13.12 and 13.20 provides the City with legal authority to regulate the flow of wastewater into its sewerage system. The Municipal Code meets the minimum legal requirements of the State Water Resources Control Board. The current Municipal Code Sections were principally ad opted through Ordinance 90 -28 in 1990; additional amendments were adopted in 1993 and 1996. While the current ordinance remains adequate to meet the minimum legal requirements, it is anticipated that Municipal Code will be updated within the next 2 -3 years to reflect more current terminology and references as well as to ensure that the Code reflects actual practices and enforcement activities within the City.

Chapter 13.20 sets forth uniform requirements for anyone who discharges wastewater into the sewage system of the city and also sets forth procedures for complying with requirements placed upon the City by other regulatory agencies. This chapter shall be known as the "sewer use ordinance" and will be interpreted with the definitions set forth in Section 13.20.020 . The sewer use ordinance develops procedures to establish quantity and quality limitations on all wastewater discharges that may adversely affect the city's public sewerage system, and/or cause the city to violate its current sewage contract agreement with Chino Basin Municipal Water District currently known as IEUA (Inland Empire Utilities Agency).

LEGAL AUTHORITY
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 22 of 65 The sewer use ordinance also provides for wastewater pretreatment requirements, the issuance of industrial user discharge permits, control of surface discharges of wastewater, and the establishment of penalties for violation of any provision of this chapter. a. Authority to prevent illicit discharges into the City’s sanitary sewer collection system is provided by Ordinance/Code.

In accordance with the Wastewater Discharge Regulation (Sewer Use Ordinance), the City has developed procedures to establish quantity and quality limitations on all wastewater discharges, which may adversely affect the City’s public sewerage system and/or cause the city to violate its sewage contract agreement with IEUA. This chapter also provides for wa stewater pretreatment requirements, the issuance of industrial user discharge permits, control of surface discharges of wastewater, and the establishment of penalties for violation of any provision of this chapter.

Title 13 Sections 13.20.110 “Prohibited Conditions In The Public Sewerage System”, and

13.20.115 “Prohibited Discharges To The Public Sewerage System” prohibit the unauthorized discharge of rain, surface or subsurface water, chemicals, debris, or any hazardous substance or waste, as currently defined by the EPA or Title 22, of the California Administ rative Code. Other sections of the code that prohibit various forms of illicit discharges are 13.20.130 “Limitation On Point Of Discharge,” and 13.20.140 “Dilution Prohibition.”
All industrial users and other users discharging industrial wastewater to the city's public sewerage system, directly or indirectly are evaluated based on the volume, type of industry, characteristics of the wastewater proposed to be discharged and the risk that it proposes to both the collection system and IEUA facilities in order to determine whether a Permit is required. Industrial user discharge permits shall be subject to all provisions of Section 13.20, other applicable regulations, charges for use, and fees established by the city. Conditions of industrial user discharge permits shall be uniformly enforced by the city in accordance with Section 13.20 and applicable federal and/or state regulations.

In Lieu of the Regional Pretreatment Agreement, the City's sewage treatment services are currently provided based on the Authority of IEUA's ordinance #114.

In addition, the Santa Ana Regional Water Quality Control Board has provided IEUA with the authority to regulate discharges into the City’s sewerage system from industrial users. The City of Chino, under the terms of the Regional Pretreatment Agreement, granted IEUA the authority to regulate industrial users within the City. SIU permits are issued through IEUA. Non-SIU permits are issued by the City only. This authority is set forth in the Municipal Code under Chino Basin Municipal Water District.

The City's pre-planned collaboration and coordination with storm drain agencies.

The City owns and operates the storm drain system within the City Limits. Both the sewer and storm drain facilities are within the Streets and Sewer Division. Should sewage discharge to a storm drain facility, City staff has full authority mitigate the impact of the spill. b. Require that sewer system components and connections be properly designed and constructed.

Chapter 13.12, “Sewers—Connections and Extensions,” sets forth the requirements for all new construction within the City and shall be connected to the City’s sewer system. Chapter 13.12 will set forth the requirements for the location of sewer lines, the standards for c onstruction, and the requirements for inspections.

LEGAL AUTHORITY
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 23 of 65 Section 13.12.060 , “Sewer mains and sewer laterals —Construction, Inspection and Acceptance,” requires that the City provide the engineering, let bids and be responsible for the construction, inspection, and acceptance of sewer lines in existing streets. However, if the sewers are to be constructed by the developer, the developer shall be responsible for the engineering and construction. In all cases, the city shall inspect and accept the sewer lines and shall decide the size and type of construction.

While the City is responsible for sewer lines established in the public right-of-way, Section 13.12.150 “Maintenance—Upper Sewer Laterals” establishes that the owner of each parcel of land that is served by a sewer lateral shall be responsible for the cleaning, repair, maintenance, and replacement of that sewer lateral.

In order to assist in the design, construction, and inspection of the sewer system, the City utilizes the current version of Standard Specifications for Public Works Construction (The Green Book), City Engineering Standards as prepared by the City and adop ted in July 2025 , and the most recently adopted version of the California Uniform Plumbing Code. Both the Public Works Department and the Development Services Department have responsibility and authority to review the plans and specifications submitted to the City as related to the installation of sewer c. Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the Enrollee.

City Municipal Code (CMC), Title 13, Section 13.20.200, as adopted by the City, gives the authorized representative of the Director of Public Works the legal right to unrestricted access to the sewer infrastructure located in private property. In accordance with the CMC, no person shall interfere with, delay, resist, or refuse entrance to an authorized and identified City repr esentative attempting to inspect any facility involved directly or indirectly with a discharge of wastewater to the City’s sewerage system. The Director of Public Works shall have the right to set up on the user’s property such devices as are necessary to conduct sampling, inspection, compliance monitoring, and/or metering operations.
d. Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures.

The City Municipal Code, Section 13.20.400 outlines the City’s enforcement mechanisms. This section includes the following enforcement actions as appropriate:
• Verbal Warning - A verbal warning will be given for violations such as housekeeping practices, late reports, etc. Verbal warnings do not apply to violations of any discharge limit or prohibition.

The verbal warning will be documented with a written follow-up letter. • Written Warning - For failure to comply with a verbal warning, a written warning with a compliance date will be issued. Written warnings do not apply to violations of any discharge limit or prohibitions.
• Notice of Noncompliance - A notice of non-compliance shall be issued whenever an industrial user discharge permit violation that does not imminently endanger human health or welfare occurs. The notice of non -compliance shall be served in person by a city representative or by certified or registered mail, return receipt requested, and shall require a response within no more than ten working days. If the permittee claims immediate correction of the violation(s) this shall be verified at the permittee's expens e. However, if the permittee suggests a time schedule to correct the permit violations, and if in the opinion of the Director of Public Works,

LEGAL AUTHORITY
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 24 of 65 a time schedule is required to obtain compliance, an administrative order shall be issued. The determination of noncompliance, for the same violation, shall be made during a consecutive six-month period of time. Such an order may include the appropriate violation assessments:
 The first notice of noncompliance shall have at a minimum a one-hundred-dollar penalty assessment.
 The second notice of noncompliance for the same violation(s) shall have at a minimum a two hundred-fifty-dollar penalty assessment.
 The third notice of noncompliance for the same violation(s) shall have at a minimum a five-hundred-dollar penalty assessment.
• Administrative Orders - The Director of Public Works may require compliance with this chapter, permit conditions, or limitations by issuing administrative orders enforceable in a court of law, or by seeking a direct action. The following lists the types of administrative orders that shall be utilized by the city:
• Cease and Desist Order - Upon finding that a discharge has taken place in violation of prohibitions or limitations of this chapter or the provision of the industrial user discharge permit, the Director of Public Works may issue a cease -and-desist order and direct those persons in violation to comply immediately or comply in accordance with a time schedule. All cease-and-desist orders shall have at a minimum a one-thousand-dollar penalty assessment. • Consent Order - Upon finding that an industrial user will need to install pretreatment equipment in order to come into compliance, the director of public works may require that a compliance time schedule, agreed upon in advance by the industrial user and the city staff, be contained in a consent order. All consent orders shall have at a minimum a five-hundred-dollar penalty assessment.
• Show Cause Order - This order requires an industrial user to appear at City Hall at a certain date and time to show cause to the City as to why criminal and/or civil actions should not be taken against this industrial user. All show -cause orders shall have at a minimum a seven hundred fifty-dollar penalty assessment.
• Compliance Order. This order will direct an industrial user to achieve or restore compliance by a specific date. The terms of the order need not be discussed with the industrial user in advance.

All compliance orders shall have at a minimum a one- thousand-dollar penalty assessment.

In addition, the City reserves the right through Section 13.20.410 “Termination of services” that any industrial user discharge permit may be revoked, and any sewerage service to any industrial user may be suspended by the Director of Public Works, if the industrial user is in violation of any provision of this chapter or of applicable state and federal regulations. In the event the user fails to comply voluntarily with the administrative order, the City shall take such steps as deemed necessary, including but not limited to the immediate severance of the sewer connection, revocation of the industrial user discharge permit, and/or termination of water service, to prevent or minimize damage to the city's sewerage system, POTW and/or endangerment to any individual.

The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valve s, and applicable stormwater conveyance facilities within the sewer system service area boundaries.”

COMPLIANCE
The above items are addressed below:

The City maintains an ARC-GIS-based mapping system in ArcGIS geodatabase format. This mapping system provides up-to-date mapping information of the sanitary sewer system showing all gravity line segments, manholes, pumping facilities, lift stations, pressure pipes, valves, casings, lat erals, and stormwater conveyance facilities. The system has the functionality to access all information related to any sewer asset and can be used to print maps, as necessary.

Historic sewer facility maps, including engineering and construction drawings (blueprints) are stored electronically on a central computer system. All paper originals are stored in a fireproof archive vault.

System maps include gravity mains, force mains, manholes, pu mp stations, property boundaries and addresses, creek locations, and storm drain mapping , and pipe asset information . Field operators utilize paper map books for routine operations and maintenance activities.

The City has a procedure for updating any map errors, omissions, or implementing necessary changes on a continuous basis. Field operators have the option for marking-up paper maps with recommended changes which reviewed by the collection system Supervisor. Any necessary changes are updated online and sent to the City’s GIS department for updating.

All "accepted" areas have plans and permits that have been finalized. These are then turned over to I.T. for adding these locations and information to the GIS however there is a current backlog for implementation.

The City can make its current sewer maps available to Water Board staff upon request.

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

COMPLIANCE
The above items are addressed below:

Gravity Main Cleaning
Sewer Line Cleaning is accomplished through the implementation of a work -order based system. Work is planned in advance. Service Requests are issued to staff to follow-up on any concerns such as odors, blockages, overflows, pests, broken or missing manhole lids, etc.

The City owns and operates two combination trucks which are used to clean sewer mainlines with a goal of cleaning the entire collection system every 6 years.

After a section has been cleaned, Public Work service staff complete a cleaning record which includes the following information:
• Date and time of cleaning.
• Method of cleaning
• Names of collections workers
• Location of the cleaning
• Location and cause of any blockage if found.
• Recommendation(s) of required further actions.

Upon completion of the day’s activities all cleaning information and work orders are returned to the Public Works Services Office for entry by the collection system Supervisor into a database.

Manhole Inspections
The manhole interior and exterior surfaces are inspected on an as- needed basis for any structural defects, sewage flow condition, presence of vermin or rodents, deleterious industrial waste, odors, and any signs of unusual settlement around the manholes and along sewer alignments.

Vermin and Rodent Control
Sewers infested by insects are chemically treated. Those infested by rodents are baited.

OPERATION AND MAINTENANCE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 37 of 65 Sewage Pump Stations
The City owns three pump stations however operates two pump stations at the present time and each are inspected weekly. These pump stations are equipped with alarm systems and are inspected regularly. They also have backup bypass pumps and mobile generators in case of emergency shutdown. All pump stations include emergency signage installed to allow the public to contact the City for any sewer emergencies for these facilities.

Gravity Mainline Inspections
To ensure that these problems are properly mitigated, city staff complete some CCTV inspections and also work closely with outside contractors performing video inspection work on the City’s sewer lines to document gravity mainline pipes and problems. The return interval for inspecting the entire sewer system is currently approximately every 6 years and is currently projected to decrease this frequency due to the addition of a new CCTV van in the City’s fleet expected to be online in summer of 2025.

Easement Maintenance
The City initiated an easement maintenance program starting in early 2025 which includes maintaining roads and difficult to access locations in the collection system.

Pipe Repairs/Rehabilitation
The City’s Rehabilitation and Replacement Plan is comprised of several processes including regular sewer line inspections and CCTV inspections. Public Works services staff and contractors perform sewer line inspection and CCTV inspections and report the conditions of sewer pipes. When a deficiency is identified, a work request is sent to Engineering staff to determine an appropriate remedy. If the problem is designated as an emergency, the necessary resources and personnel are assigned in a timely manner. I f it is not an emergency, the pipeline repair/replacement is prioritized, scheduled, and placed within the CIP in conjunction with other sewer projects. Funding for rehabilitation and replacement projects is another integral part of the Rehabilitation and Replacement Plan. Budget amounts change from year to year based on the expected projects for each year; the Capital Improvement Program (CIP) budget contains funds for miscellaneous sewer repairs.

Lateral Program
In November of 2023, the City amended section 13.12.150 of the municipal code to reflect the City's new responsibility of the lower sewer lateral located in the public right -of-way as it relates to cleaning, repair, maintenance, and replacement. Currently, when notified, City Wastewater staff will respond to issues and or blockages related to residential or commercial properties. If it is determined the blockage or issues are caused by the lower lateral, City Wastewater staff will make the necessary repairs.

The City is actively working on a formal lower sewer lateral maintenance program that can be implemented as a proactive approach to identifying aging infrastructure and utilizing the information in collaboration with the City's CIP team to address these deficiencies, if possible, during a street rehab project.

5. Design and Performance Provisions

5.1. Updated Design Criteria/Construction Standards/Specifications

WDR REQUIREMENTS
Attachment D-5.1 (pg. D-5)
“Updated design criteria, and construction standards and specifications, for the construction, installation, repair, and rehabilitation of existing and proposed system infrastructure components, including but not limited to pipelines, pump stations, and other system appurtenances. If existing design criteria and construction standards are deficient to address the necessary component-specific hydraulic capacity as specified in section 8 (System Evaluation, Capacity Assurance and Capital Improvements) of this Attachment, the procedures must include component-specific evaluation of the design criteria.”

COMPLIANCE
The above items are addressed below:

Written Design Standards: Design standards usually included written documents and standards that tell a design engineer how to design a gravity sewer, pressure sewer, sewage lift stations, and other sewer appurtenances.

For each new sewer project, a properly designed set of plans, consistent with the standard specifications is then submitted to the City for review and approval. This step represents a critical part of the sewer design and construction process in that the plans must be checked for conformance with the design, construction, and manholes standards.

It is optional that each city has its own specific sewer construction standards or specifications.

The purpose of this element is to ensure that all sewers within the City are designed and constructed with generally accepted engineering and industry standards.

As a starting point, all projects will have accurate flow projections, Hydraulics of Sewers, and planning and Design Criteria.

Sewer Materials and Structures: Sewer pipes, reinforced concrete box, sewer pipe joint, sewer maintenance holes, other sewer maintenance structures, spacing, excavations, bedding, backfills, and other specifications are clearly laid out the set of plans.

Sewer Construction: It is the responsibility of the City to ensure that the contractors and engineers follow its construction standards and City provides an oversight for ensuring they are built as per design documents, or “As Built Drawings” are provided to the City. Similar standards are also applicable to sewer rehabilitation projects to improve sewer system performance.

Description of City Process: The City requires that all sewers be designed and constructed are done in accordance with the City Standard Plans and Specifications. The City’s specifications by reference incorporate the most recent edition of the Green Book “Standard Plans and Specifications for Public Works Construction, Special Provisions, and Standard Drawings” and the most recent California Plumbing Code, “California Code of Regulations” Title 24, part 5 issued by The California Building Standards Commission.

The City requires that plans be designed or prepared under direct supervision of licensed engineers and

DESIGN AND PERFORMANCE PROVISIONS
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 40 of 65 provides a thorough review of plans by the City’s plan check staff prior to approval for construction and inspection of the actual construction work.

Since the Green Book and the California Plumbing Code are large documents, they are located in this document’s reference list. The City’s Standard Plans and Specifications address all routine sewer design and construction activities. However, design of specialty facilities such as sewage lift stations and/or large diameter sewer lines are handled on a case-by-case situation.

Once the sewer project is designed properly and the contractor has approved set of construction plans and specifications, the City ensures the new or rehabilitated sewers are properly constructed before the City will accept operation and maintenance responsibility. City staff or outside consultants perform construction inspection as deemed appropriate by the City. It is, however, not required that the inspector be at the construction at all times. The inspector usually provides a written record of each inspection and a final acceptance authorization.

The City provides inspection by utilizing its own staff or outsourcing to qualified consultants and/or contractors for the inspection of new sewer construction projects. The inspection of new sewers and the replacement and/or rehabilitation of existing sewers is conducted by City-trained inspectors. The City requires that “As-Built” sewer plans of the completed projects be submitted prior to final approval for acceptance of sewer facilities for public use. In addition, after completion of any sewer mains, t he City requires a video inspection of the completed sewer to ensure that newly constructed sewer is free from cracks, any foreign objects debris or settlement of debris. If at any point during design or construction stage a dispute arises or if the design engineer or contractor deviated from as approved plans, the dispute resolution process will timely and effectively resolve the matter to the City’s satisfaction.

5.2. Procedures and Standards

WDR REQUIREMENTS
Attachment D-5.2 (pg. D-5)
“Procedures, and standards for the inspection and testing of newly constructed, newly installed, repaired, and rehabilitated system pipelines, pumps, and other equipment and appurtenances.”

COMPLIANCE
Public Works services staff perform many operational and maintenance activities to ensure the reliable performance of the collection system. Sewer lines are cleaned of roots, debris, grease, etc. Sewer cleaning is performed by using high pressure hydro -jetting equipment, specialized root cutters, and other equipment. As the cleaning is performed, Public Works Wastewater Staff is also performing visual inspections of manholes to see if there is evidence of surcharge, vandalism, structural damage, and other infrastructure concerns. The Collections Systems goal is to clean the entire system every 6 years.

The City also contracts to have video inspection for at least 10-miles of its sewer main collection system on an annual basis. During this video inspection, the sewer is also cleaned.

Sewer overflow problem areas known as hot spots are cleaned more frequently, monitored on a monthly basis, and controlled aggressively.

The City owns and operates two vacuum jet trucks which are used to clean the sewer mains, sewer laterals, cleanouts, storm drains and catch basins.

Sewer Line Cleaning is accomplished through the implementation of a work -order based system. Work is planned in advance. Service Requests are issued to staff to follow -up on any concerns such as odors, blockages, overflows, pests, broken or missing manhole lids, etc.

Work orders are issued for all maintenance management activities, inspections, customer service calls, and spill responses. This includes issuing work orders for scheduled and unscheduled inspections, cleaning, and other maintenance activities. Work orders provide staff with a daily schedule and cleaning route. After a section has been cleaned, Public Work Wastewater staff complete a cleaning record which includes the following information:
• Date and time of cleaning.
• Method of cleaning
• Names of collections workers
• Location of the cleaning
• Location and cause of any blockage if found.
• Recommendation(s) of required further actions.

Upon completion of the day’s activities all cleaning information and work orders are returned to the Public Works Services Office for entry into the database. The City uses tracking software to log and track field activities. The following summarizes the City’s preventive maintenance work performed by the City:
• Manhole Inspection - The manhole interior and exterior surfaces are inspected on an as - needed basis for any structural defects, sewage flow condition, presence of vermin or rodents, deleterious

DESIGN AND PERFORMANCE PROVISIONS

• Drop Manholes - These facilities are inspected and cleared of stoppages and flow restrictions on variable frequencies based on prior inspection records. • Sewer Line Cleaning - Sewer lines are cleaned by hydro jet or rodding based on an as- needed cleaning schedule. Additional cleaning and hydro jetting is performed in areas with excessive accumulation of grease, garbage, grinds, or sand build up. Special cleaning is performed based on the history of the sanitary sewer buildup at recurring locations. • Vermin and Rodent Control - Sewers infested by insects are chemically treated. those infested by rodents are baited.
• Sewage Pump Station - The City owns and operates two pump stations at the present time. These pump stations are equipped with alarm systems and are inspected regularly. They also have backup pumps in cases of emergency shutdowns.

7. Sewer Pipe Blockage Program

WDR REQUIREMENTS
Attachment D-7 (pg. D-7)
“The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed.

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

COMPLIANCE
In many sanitary sewer collection systems, Fats, Oils, and Grease (FOG) is known to be a significant cause, and or contributor, of sewer blockages in pipe and the cause of operational disruptions and damage to sewage pump stations . Although service areas that include commercial and institutional food service establishments (FSEs) are obvious sources of FOG, residential communities, especially those of medium and high-density multi-family residences, can also be a significant source of FOG . It is the purpose of the Regional FOG Control Program to ensure all customers in our service area are following the City Ordinance, and state and federal requirements, to prevent sewage overflows caused by FOG related blockages in our sewer collection system.

FOG Control Programs are required to include specific elements in order . The City of Chino has evaluated its sewer service area and determined a FOG control program is needed . The City has, developed the following FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system.

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 46 of 65 Public Outreach
The City developed an appropriate outreach program that includes educating all Food Service Establishments identified by the City through both the FOG Inspection Program as well as the NPDES MS4 Inspection program. Education and outreach materials are provided at each inspection. This education program includes a tri -fold brochure, which provides information on the proper management of an FSE’s grease and oil generation, maintenance, and operation of grease interceptors, how to locate grease collection companies, and what will typically happen during a FOG inspection. A sample of a typical outreach hand-out is available at San Bernardino County Stormwater Program website, shown below:
• https://sbcountystormwater.org/wp-content/uploads/2017/05/Food-Restaurants.jpg Currently, the San Bernardino County Stormwater program has developed an educational program focused on residential cooking oil disposal that includes information regarding the proper disposal of home - generated cooking oils. An English and Spanish version of the handout is available at the following two websites:
• https://sbcountystormwater.org/wp-content/uploads/2018/10/cookingoilenglish.pdf • https://sbcountystormwater.org/wp-content/uploads/2018/10/cookingoilspanish-1.pdf The City will use these materials to provide outreach to the residential communities, through local channels, events, and the City’s periodic newsletter, “Chino Connection.” The information will be in the form of page advertisements within the newsletter.

In addition, both the City’s FOG and NPDES inspection programs will include distribution of appropriate Best Management Practice materials during the routine inspections.

Disposal of Pipe Blocking Substances
The City requires each FSE to make arrangements for the proper disposal of FOG generated by the FSEs.

During periodic inspections conducted under both the FOG and NPDES programs, conducted every 1, 2, or 5 years based on the risk history of noncompliance, each FSE’s FOG disposal records and manifests are reviewed to ensure that the FSE is properly disposing of the FOG. The City inspects for FOG annually for high risk, every other year for medium risk, and also inspects at an i ncreased frequency such as every 4-6 months in cases where FSEs are repeatedly non-compliant.

City will evaluate the records in conjunction with the interceptor to ensure its operating properly and all components are in place. Grease interceptors are regulated at the 25% rule where if 25% of the interceptor’s capacity is remaining, the City will direct the FSE to pump the interceptor immediately.

These manifests should include the grease disposal firm’s name, address, amount of grease removed, and the date of service. In the event that a record is not on-site during the inspection, the City typically will issue a Notice of Correction under either program. Many franchise FSEs will submit these records to a central corporate facility. The City will require that the FSE keeps copy on site or retrieve said inspection record as part of the NOC and will schedule a revisit to review this record.

The City provides a list of local grease disposal companies that are available on the City’s website. In addition, the County of San Bernardino Stormwater Program recommends that FSEs search for grease disposal or rendering services within the telephone directory. The County program provides a phone number (909-386-8401) for additional resources.

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. SSMP licensed for City of Chino use only. Page 47 of 65 Typically, when the City conducts a FOG inspection, the City will open and inspect the grease interceptor on-site and perform a physical measure of the remaining volume. If there is an accumulation of 25% or more of grease and solids within the operating fl uid capacity of the interceptor, a mandatory pumping is required. Usually, the volume of grease present will determine the schedule for interceptor pumping. The grease interceptor is verified to have all components such as inlet tee, baffle tees, outlet tees or walls to function properly. The following is an example of an Interceptor Inspection form, which indicates the required frequency of servicing depending on accumulation, with grease in the sample box requiring interceptor servicing within 24-hours. This form also provides a method for determining if the interceptor requires any type of repairs.

Legal Authority (Prohibit Discharges)
The City’s current ordinance provides the legal authority to prohibit discharges of FOG to the sewer system.

Section 13.20.115 “Prohibited discharges to the public sewerage system,” in which paragraph A identifies as prohibited any “Waste and/or wastewater that contains substances that may precipitate, solidify and/or become viscous at temperatures between fifty degrees Fahrenheit or ninety degrees Fahrenheit.” The City undertakes routine maintenance activities relating to the FOG program, including routine CCTV inspections of sewer lines and line cleaning to prevent the build-up of FOG within the City’s sewer lines.

Based on historical knowledge of the sewer system, the City focuses additional resources in those areas in which FOG buildup may have occurred in the past, or in which a large number of either Food Service Establishments (FSE) or residential apartment complexes are located which, due to the City’s socioeconomic make-up, may have increased cooking oil discharges. The City believes that the low number of spills during the last ten years is evidence that the current management approach has been effective in preventing spills and blockages caused by FOG.

Legal Authority (Grease Control Devices)
Section 13.20.200 “Inspection” of the City’s current ordinance provides adequate authority to the City to conduct inspections of grease removal devices . Currently, the City conducts FOG inspections under two separate programs, the NPDES Program which occurs annually on high priority commercial users and includes a review of grease removal records. Both inspections occur at the same time and frequency typically on an annual basis for FSEs with grease interceptors. The City is proposing to add Section 13.20.220 “Grease, Sand and Oil Interceptor Inspections” in order to further clarify the requirements for maintenance, including standards for servicing. The proposed language of this section is as follows:
“The grease or sand and oil interceptor of any facility shall be properly maintained. It shall be cleaned, as often as is necessary by the owner or user to assure that all grease, sediment, floating material, sand and oil do not accumulate to impair the efficiency of the interceptor. When an interceptor is cleaned, the accumulated sediment and floating material shall be removed and disposed of legally. Under no circumstance shall the material removed from a grease or sand and oil interceptor be discharged into a public sewer collection system, storm drain system, or ground. An interceptor is not considered properly maintained if, for any reason, it is not in good working condition. An interceptor is also not considered properly maintained if grease, sediment, floating material, sand and oil accumulations total more than twenty-five percent of the operating fluid capacity. The owner of any facility, the lessee and sub lessee, if there be such, and any proprietor, operator, or superintendent of such facility are individually and severally liable for any failure or improper maintenance of such interceptor. In addition, the grease,

Page 48 of 65 sand and oil interceptor shall be maintained so that the discharge will comply with all limits contained in the resolution titled "Wastewater Effluent Limitations." Legal Authority (Inspection of Grease Producing Facilities) Section 13.20.215 has inspection requirements allowing the City the right to inspect the user's facility and sample the user's discharge to determine compliance with this chapter. grease producing facilities.

State that City has identified portions of the system subject to FOG and describe how City maintains areas known to be subject to FOG.

The City has an established preventative maintenance program to monitor and inspect sections of sewers impacted by grease and conducts routine sewer mainline cleaning in these sections using jetting and rodding as appropriate.

COMPLIANCE
The above requirements are addressed below:

The assessment of a collection system involves every component of the City collection system, including pipelines, manholes, and pump stations. The assessment of pipeline condition is the most significant condition assessment responsibility the City has. It is of key importance to regularly perform pipeline condition assessments to initially establish a condition baseline and to monitor condition changes over time.

Technologies, Practices, Strategies
The City employs a variety of technologies, practices, and strategies for implementation of its sewer system condition assessment program as follows:
• The City utilizes and maintains an ArcGIS Geodatabase software to manage sewer infrastructure and maps The City conducts Closed -Circuit Television (CCTV) inspections with its own equipment/staff and supplements some sections with outside contracted services . The City’s current CCTV interval for inspection of the entire sewer system is approximately every 9 years. New sanitary sewer construction and/or major sewer reconstructions are completed based on site -specific designed plans and specifications using the “Public Works Standard Plans and Specification” (Green Book) as well as the City’s Standard Engineering Designs. Sewer plans and specifications are designed with sufficient capacity for current and future base, peak, and wet weather flow demands, including evaluation of impacts from proposed projects on the existing sewer system. • The City also relies on modern Master Planning techniques for further evaluation of both capacity and condition assessment of sewers. The city completed an original Sewer Master Plans in 2011 that included evaluating hydraulic and modeling the hydraulic conditions for base flow s, peak flow s, sewer flow velocity, and d/D flow depth to pipe diameter ratio . A 2022 Sewer Master Plan 2 was completed to update the 2011 Plan that included comprehensive assessments of existing and future sewer design capacities due to the expanding growth of residential, commercial, and industrial projects proposed within the City’s sewer service area. The City revised its 2011 Sewer Master Plan in 2022 Sewer Master Plan that includes the following updates:
o Evaluate existing and future sewer system capacity and existing sewer asset condition for development of a phased approach for the City’s sewer capital improvement program with capacity and condition related projects.
o Create a dynamic GIS database for leveraging multiple operational and project planning including integration of data into an asset management system.

The key objectives of the 2022 Sewer Master Plan included the following tasks that were completed:
• Review of the wastewater layer of the City’s GIS including all wastewater lines (excluding laterals) and update as needed.
• Evaluate of whether a survey of sewer manholes is needed and to what extent. • Construction of a sewer model.
• Utilization of the model to identify those portions of the wastewater system that are overloaded under existing and future conditions.

Page 52 of 65 • Development of a capital repair and replacement program that will establish an appropriate rate of renewal and capital investment.
• Preparation of a prioritized Capital Improvement Program that will address identified capacity and condition-related deficiencies.

Justification for Condition Assessment
The City has one CCTV van dedicated to the inspection of sewer mains and lower laterals. Staff assesses the condition of the collection system on an 8-year interval. The City maintains a relatively low spill rate which is continuously assessed to help ensure an optimal inspection cycle. Having the new CCTV van allows staff to inspect laterals and mainlines in a timely manner not relying on contracted services and their schedule therefor improving the efficiency. Prioritize Condition Assessments The City inspects all gravity mains and manholes and is knowledgeable about the performance of its collection system. Staff believes it is appropriate to address all pipe segments in the same manner as the risk and consequence of a spill from any portion of the collection is essentially the same.

The City performs top-down, visual inspections of manholes and video inspections of gravity mains. Level sensors (SmartCovers) are also utilized to monitor flow conditions, pipe performance, and infiltration.

The City is not aware of exfiltration from their collection system.

CCTV Inspections
Data is collected, compiled, and used for the purpose of documenting maintenance efforts, evaluating system performance, and making maintenance and corrective action decisions today and into the future.

Climate Impacts
The City continuously monitors potential impacts due to climate change. The City has determined that flooding is its single most impact that affects the sanitary sewer collection system. To address this issue, the City has identified areas susceptible to flooding and continuously adds composite manhole covers to reduce inflow in targeted areas throughout the collection system. A copy of the City’s 2020 -2030 Climate Action Plan (CAP) can be found at: https://www.cityofchino.org/206/Climate-Action-Plan-CAP

The sanitary sewer collection system capacity enhancement program is based on the Sewer Master Plan, internal inspections, and capacity analysis that are used to compile and prioritize capital projects. The prioritized capital projects are scheduled as part of the five- year CIP budget process. Projects are scheduled based on severity of needs and availability of funding. The five-year CIP program is adjusted annually based on changes in priorities. For FY20 -21, the Sewer CIP includes approximately $4,468,9 39 in planned Sewer System Improvements. The table below shows the list of projects planned from FY19-20 through FY23-24.

Point or immediate repairs are made soon after discovery and are frequently re -prioritized to ensure uninterrupted sewer service. Point repairs are a part of the City’s annual repair and replacement budget.

8.3. Prioritization of Corrective Action

WDR REQUIREMENTS
Attachment D-8.3 (pg. D-9)
“The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills.”

COMPLIANCE
The City relies both on existing CCTV data for identifying issue areas for prioritizing collection system repairs and replacements along with recommendations identified in both its completed 2011 and 2022 Sewer Master Plans.

The 2011 Sewer Master Plan identified individual capacity improvements and individual condition improvements based on flow monitoring and modeling . The 2022 Sewer Master Plan (see Appendix 8. 1) identified a total of thirteen (13) individual capacity improvements (see Appendix 8.1, Table 8.1) and seven (7) individual condition improvements (see Appendix 8. 1, Table 8.4) were identified and recommended based on risk of surcharging.

The City is currently evaluating recommendations specified in its 2022 Sewer Master Plan for potential Capital Improvement Program (CIP) projects. The City anticipates providing an update on these recommendations in its next SSMP Audit due in 2027.

The City is not aware of exfiltration from their collection system. The City has identified many sewage conveyance facilities near surface waters. Approximately 11,000 feet of gravity main runs parallel to creeks and some have been lined. Other pipes located near surface water are located within the public right -of- way, in streets and show no evidence of defects that could lead to exfiltration. The City continuously monitors defects such as cracks, separated joints, and infiltration. Significant findings will be addressed in a timely manner.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Has the City adhered to its system evaluation/condition assessment schedule? • Has the City adhered to its prioritization/corrective procedures for sewer repair and capacity improvement projects?

WDR REQUIREMENTS
Attachment D-9 (pg. D-9)
“The Plan must include an Adaptive Management section that addresses Plan -implementation effectiveness and the steps for necessary Plan improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate Plan activities;
• Monitoring the implementation and measuring the effectiveness of each Plan element; • Assessing the success of the preventive operation and maintenance activities:
• Updating Plan procedures and activities, as appropriate, based on results of monitoring and performance evaluations; and
• Identifying and illustrating spill trends, including spill frequency, locations, and estimated volumes.”

COMPLIANCE
The above requirements are addressed below:

The City maintains accurate and relevant inspection and maintenance records for the collection system .

Much of the documentation today is maintained electronically, which allows for ease of access and analysis.

This helps City staff to make sound decisions and prioritize activities when dealing with the routine and the unexpected.

Monitoring of the City’s SSMP focuses on each element in terms of its implementation and effectiveness.

The SSMP has been designed to include key performance indicators for each element, which are used to measure effectiveness. In addition, implementation responsibilities are included for each element to help ensure the SSMP is being implemented as intended.

The City assesses the success o f maintenance and operation activities by ensuing activities are being performed as expected, by monitoring actual outcomes compared to intended outcomes, as well as monitoring spill trends.

The City is committed to continuous improvement and monitors and evaluates performance of work programs and SSMP elements to ensure intended outcomes are achieved while looking for areas for improvement. Although the SWRCB requires that the SSMP be updated every six years, the SSMP should be considered as a dynamic document and may require updating on a more frequent basis. Routine changes to administrative information, notwithstanding, minor changes will likely be required to address improvements identified through the SSMP Audit or through modifications required as conditions change.

The City monitors spill trends, at a minimum every three years during required audits, utilizing the CMMS database, inspection records, and CIWQS data. These resources are helpful in planning and programing work, and adjusting as needed, enabling the City to be adaptive and capitalize on lessons learned.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Are SSMP Elements being periodically evaluated for effectiveness? • Are work activities and spill events being documented? • Has a plan and schedule been established to address audit findings/deficiencies from the last audit? • Is Trend Analysis being performed on spill causes?

11. Communication Program

WDR REQUIREMENTS
Attachment D-11 (pg. D-10)
“The Plan must include procedures for the Enrollee to communicate with:
• The public for:
o Spills and discharges resulting in closures of public areas, or that enter a source of drinking water; and
o The development, implementation, and update of its Plan, including opportunities for public input to Plan implementation and updates.
• Owners/operators of systems that connect into the Enrollee’s system, including satellite systems, for:
o System operation, maintenance, and capital improvement-related activities.”

COMPLIANCE
When the City experiences a spill, it is standard procedure to secure the affected area and keep the public away. This is generally done using barricades, cones, and caution tape . Should the City experience a spill that may require closure of public areas or enter a source drinking of water, signs will be immediately placed indicating the issue and providing contact information. Staff will remain on site to provide an additional safety factor until appropriate authorities respond and direct otherwise. In all cases, the City will follow the advice of higher authorities, such as the local environmental health department and other regulatory authorities.

There are several opportunities for stakeholders and the public to participate and provide input into the development and update of the City SSMP. During its initial development stage, as with each SSMP Audit and update of the SSMP, the SSMP and related documents are presented to the City Board for approval.

Prior to each Board or Council meeting, these documents are included in Board Agenda packet which are readily available for review on the City’s website. The SSMP is posted on the City’s website, which provides the public several ways to contact the City, via the “Contact Us” feature.

The City does not currently have satellite systems.
