LETTER OF RECOMMENDATION FOR G2 CONSTRUCTION, INC.

G2 Construction (G2) has designed, fabricated, and installed thousands of their trash capture devices in the City of Los Angeles since the bureau of Sanitation and Environment (LASAN) approved their CPS inserts and ARS curb opening screens in 2013. G2’s devices are very effective at capturing trash, their installations are of high quality, and the company is professional and reliable.

In 2023, LASAN awarded G2 Construction a 10-year $8,000,000 contract to fabricate and install Full Capture Catch Basin Inserts and Curb Opening Screen Covers (G2’s CPS-Mod and ARSCL devices). G2 is one of only two approved vendors that LASAN has found acceptable to provide both the catch basin connector pipe screens (CPS) and automatic retractable screens (ARS) in City of Los Angeles public right-of-way catch basins.

G2’s installation crews are highly skilled and communicate well with inspectors, their work is performed on time and within budget, and their project management has been efficient. Their personnel are very good at providing all required documentation and making the process easy.

The approval of G2 devices by LASAN lead to the installation of their CPS-Mod and ARS-CL devices on important City projects such as:

LA World Airports Roadways (LAWA RUE). 2024
LA Metro Westside Purple Line. 2024
LA Metro Regional Connector Corridor. 2023

SUBJECT: G2 Construction, Inc. – Letter of Recommendation To Whom It May Concern:

The City of Lakewood contracted with G2 Construction on three (3) projects to install State Water Board certified CPS-Mod connector pipe screens and GITS grated inlet trash screens.

G2 successfully installed their products in 2016, 2018, and 2023 as part of the City’s FullCapture Catch Basin Insert Program to the satisfaction of the City. G2’s personnel have been very capable, and both projects installed as scheduled.

Our experience with G2 has been very positive, and I can recommend their products and services. Their team has been very professional and responsive to our needs, and they were quick to provide field evaluations of our catch basins and recommendations for our project.

Some of the City’s catch basins were unique and G2 was able to manufacture customized CPSMod devices that allowed us to meet regulations and the City’s water quality objectives.

Please feel free to contact me if you have any additional questions.

TRASH AND DEBRIS CAPTURE DEVICES – RFP# 080-2736403-WH
To Whom It May Concern:

The City of Laguna Hills has contracted with G2 Construction (G2) since 2007 to design, fabricate, and install their ARS-CL and CPS-Mod trash and debris screens throughout the City. Between 2012 - 2024, G2 installed 11 annual City projects that won OCTA Environmental Cleanup Program’s Project X grant funds. They have installed over 2,000 ARS screens and 370 CPS devices in our catch basins.

The City continues to select G2 Construction because their devices successfully prevent trash, debris, and vegetation from entering our storm drain system and watershed. The City plans to work with G2 again this year to install our Phase XII OCTA grant.

For each project G2 has provided a simple end-to-end solution that includes field evaluations and measurements of catch basins, custom design and fabrication of their devices, installation, photos, support documentation, and warranty. G2’s work has always been on schedule, on budget, and performed without any problems.

G2 has also assisted the City with an inventory of catch basin devices, and provided information critical to our Project X applications.

I am pleased to offer this letter of recommendation for G2 Construction. The City finds their trash and debris devices to be very effective and of good value, and their installation work to be of high quality. The company has been very professional and dependable in their interactions with the City. We look forward to working with G2 Construction on future projects.

You may contact me with any questions at [email protected] or 949/707-2655.

Subject: Trash Capture Device Installations by G2 Construction To Whom It May Concern:

I wholeheartedly recommend G2 Construction, Inc. (G2) following the excellent service they provided in the City of San Clemente’s most recent 2024 contract with them for the installation of trash capture devices on 78 storm water inlets.

The G2 team demonstrated expertise in the products they sell and install, as well as a commitment to delivering projects under budget and on a schedule that minimized both traffic impacts to the public and City staff time. In addition to quality, customized products, G2 provided substantial technical assistance that they have incorporated into their contract pricing. As a project manager new to the world of trash capture devices, I especially appreciated the guidance of G2 in ensuring that the work they so efficiently completed would meet the requirements for the OCTA grant funding that we obtained for the project, and also drive us closer to regulatory compliance with the Statewide Trash Amendments.

To date, G2 has installed trash capture devices on 244 inlets within the City’s jurisdiction. Although I did not oversee the previous phases of trash capture devices, I can attest that the City has had no major maintenance or quality issues with the devices constructed and installed by G2 since they first began working under contract for the City in 2022.

If you have any additional questions about G2’s work for the City, please don’t hesitate to reach out to me.

Sincerely,
Niki Beach

SUBJECT: TRASH AND DEBRIS CAPTURE DEVICES – REQUEST FOR PROPOSAL City of Seal Beach – Recommendation Letter
To Whom It May Concern:

This letter of recommendation is in response to Orange County Public Works’ Trash and Debris Capture Devices RFP. In my current capacity as the City of Seal Beach’s Public Works Director, I have had the pleasure of working with G2 Construction, Inc. (G2) for the installation of multiple capture devices.

OCPW’s master agreement in partnership with OCTA’s Environmental Cleanup Program has allowed many local agencies mitigate transportation-related pollutants. Through this, G2 has provided a seamless approach to successful project delivery, which I have no reservations recommending. The following is a recent list of services performed under my purview:
 2023 Seal Beach CPS -Mod (170 systems) + ARS (48 screens)  2020 Seal Beach CPS-Mod (53 systems) + ARS (95 screens)  2019 Seal Beach CPS-Mod (55 systems) + ARS (127 screens) Should you have any questions regarding G2’s performance, please feel free to reach out at (562) 431- 2527, x1322 or [email protected].

Upon 24-hour notice from City, CONTRACTOR shall allow City or City’s agents or representatives to inspect at CONTRACTOR’s offices during reasonable business hours all records, invoices, time cards, cost control sheets and other records maintained CONTRACTOR in connection with this AGREEMENT. City’s rights under this Section 7 shall survive for two years following the expiration or earlier termination of this AGREEMENT.

8. TIME. The term of this AGREEMENT shall be for a period as set forth in a Notice to Commence Work to be issued by the CITY. CONTRACTOR shall complete all those services set forth in its PROPOSAL by that certain date set forth in said Notice to Commence Work or until such time as the services have been completed by the CONTRACTOR and accepted by the CITY, whichever occurs first.

9. TERMINATION OF AGREEMENT.
a. Except as otherwise provided, CITY may terminate this AGREEMENT at any time with or without cause upon providing written notice to CONTRACTOR at least thirty (30) days before the effective termination date. Notice of termination will be in writing. In the event of a termination for convenience, the CITY , based upon work accomplished by CONTRACTOR prior to notice of such termination, shall determine the amount of fees to be paid to CONTRACTOR for such services based upon accepted practices of the CONTRACTOR’S field of work, and such finding by the CITY, and shall be final and conclusive as to the amount of such fee. b. Should the AGREEMENT be terminated pursuant to this Section, CONTRACTOR shall immediately cease work except for work necessary to secure the job site and any materials not yet incorporated into the work. Once the job site is secured, CONTRACTOR shall vacate the premises. CITY may procure on its own terms services similar to those terminated.
c. Upon termination of this AGREEMENT by CITY, CONTRACTOR shall transfer possession of all fixed items, including but not limited to fencing, construction trailers, and any other equipment or materials affixed to the project site, to CITY.

Maintenance Contract $30k or More
-4-
Revised-7.2025
with all necessary documentation related to the fixed items, including warranties, maintenance records, and any other relevant information. CONTRACTOR shall also coordinate with CITY to facilitate the smooth handover of these items.
d. By executing this document, CONTRACTOR waives any and all claims for damages that might otherwise arise from CITY’s termination under this Section.

10. INDEPENDENT CONTRACTOR. CONTRACTOR is and will at all times remain as to CITY a wholly independent contractor. Neither the CITY nor any of its officers, employees, or agents will have control over the conduct of CONTRACTOR or any of CONTRACTOR’s officers, employees, agents or subcontractors, except as expressly set forth in the AGREEMENT.

CONTRACTOR may not at any time or in any manner represent that it or any of its officers, employees, agents, or subcontractors are in any manner officers, employees, agents or subcontractors of CITY.

11. NONASSIGNMENT. This AGREEMENT is not assignable either in whole or in part by CONTRACTOR without the written consent of CITY. Any purported assignment without such consent shall be void and without effect.

12. INDEMNIFICATION. CONTRACTOR shall indemnify, defend with legal counsel approved by CITY—or, at the CITY’s option, reimburse the CITY Indemnitees their costs of defense—and hold harmless CITY, its officers, officials, employees and volunteers from and against all liability, loss, damage, expense, cost (including without limitation reasonable attorney’s fees, expert fees and all other costs and fees of litigation) of every nature arising out of or in connection with CONTRACTOR’s negligence, recklessness or willful misconduct in the performance of work hereunder or its failure to comply with any of its obligations contained in this agreement. CONTRACTOR’s obligations under this section apply regardless of whether or not such claim, charge, damage, demand, action, proceeding, loss, stop notice, cost, expense, judgment, civil fine or penalty, or liability was caused in part or contributed to by an Indemnitee. However, without affecting the rights of CITY under any provision of this agreement, CONTRACTOR shall not be required to indemnify and hold harmless CITY for liability attributable to the sole active negligence of CITY, provided such active negligence is determined by agreement between the parties or by the findings of a court of competent jurisdiction. In instances where CITY is shown to have been actively negligent and where CITY’s active negligence accounts for only a percentage of the liability involved, the obligation of CONTRACTOR will be for that entire portion or percentage of liability not attributable to the active negligence of CITY.

Should conflict of interest principles preclude a single attorney from representing both CITY and CONTRACTOR, or should CITY otherwise find CONTRACTOR’s attorney unacceptable, then CONTRACTOR shall reimburse the CITY its costs of PAGE 302 of 623
Maintenance Contract $30k or More
-5-
Revised-7.2025
defense, including without limitation reasonable attorney’s fees, expert fees and all other costs and fees of litigation. The CONTRACTOR shall promptly pay any final judgment rendered against the CITY (and its officers, officials, employees, and volunteers) with respect to claims determined by a trier of fact to have been the result of the CONTRACTOR’s negligent, reckless, or wrongful performance.

Payment by CITY is not a condition precedent to enforcement of this indemnity. In the event of any dispute between CONTRACTOR and CITY, as to whether liability arises from the sole active negligence or willful misconduct of the CITY or its officers, employees, or agents, CONTRACTOR will be obligated to pay for CITY’s defense until such time as a final judgment has been entered adjudicating the CITY as solely negligent or to have acted with willful misconduct. CONTRACTOR will not be entitled in the absence of such a determination to any reimbursement of defense costs including but not limited to attorney’s fees, expert fees, and costs of litigation.

It is expressly understood and agreed that the foregoing provisions are intended to be as broad and inclusive as is permitted by the law of the State of California and will survive termination of this agreement.

13. NON-DISCRIMINATION. CONTRACTOR shall not discriminate in its recruiting, hiring, promotion, demotion or termination practices on the basis of race, religious creed, color, national origin, ancestry, physical disability, mental disability, medical condition, martial status, sex, age, or sexual orientation in the performance of this AGREEMENT and shall comply with the provisions of the California Fair Employment and Housing Act as set forth in Part 2.8 of Division 3, Title 2 of the California Government Code; the Federal Civil Rights Act of 1964, as set forth in Public Law 88-352, and all amendments thereto; Executive Order 11246; and all administrative rules and regulations issued pursuant to such acts and order.

14. PREVAILING WAGES. CONTRACTOR is aware of and agrees to abide by the provisions of California Labor Code Sections 1720, et seq., as well as 1771, 1773, 1773.1, 1773.6, 1773.7, 1775 and 1776, pertaining to the obligation to pay prevailing wages with respect to the performance of work as described in Paragraph 2 herein. Copies of the prevailing rate of per diem wages and the general prevailing rate for holiday and overtime work for each craft are available upon request from the CITY. A copy of the prevailing rate of per diem wages shall be posted at the job site. CONTRACTOR and its subcontractors must keep accurate certified payroll records showing the name, occupation, and the actual per diem wages paid to each worker employed in connection with this AGREEMENT. If requested by CITY, CONTRACTOR must provide copies of the records at its cost.

15. UNAUTHORIZED ALIENS. CONTRACTOR hereby promises and agrees to comply with all of the provisions of the Federal Immigration and PAGE 303 of 623
Maintenance Contract $30k or More
-6-
Revised-7.2025
Nationality Act (8 USCA 1101, et seq.), as amended; and, in connection therewith, shall not employ unauthorized aliens as defined therein. Should CONTRACTOR so employ such unauthorized aliens for the performance of work and/or services covered by this AGREEMENT, and should the Federal Government impose sanctions against the CITY for such use of unauthorized aliens, CONTRACTOR hereby agrees to, and shall, reimburse CITY for the cost of all such sanctions imposed, together with any and all costs, including attorney’s fees, incurred by the CITY in connection therewith.

16. WAIVER. Waiver by any party hereto of any term, condition, or covenant of this AGREEMENT shall not constitute the waiver of any other term, condition or covenant hereof.

17. ATTORNEY’S FEES. If litigation is reasonably required to enforce or interpret the provisions of this AGREEMENT, the prevailing party in such litigation shall be entitled to an award of reasonable attorney’s fees, in addition to any other relief to which it may be entitled.

18. BINDING EFFECT. This AGREEMENT shall be binding upon the heirs, executors, administrators, successors and assigns of the parties hereto.

19. PROVISIONS, CUMULATIVE. The provisions of this AGREEMENT are cumulative and in addition to and not in limitation of any rights or remedies available to CITY.

20. NO PRESUMPTION RE: DRAFTER. The parties acknowledge and agree that the terms and provisions of this AGREEMENT have been negotiated and discussed between the parties and their attorneys, and this AGREEMENT reflects their mutual AGREEMENT regarding the same. Because of the nature of such negotiations and discussions it would be inappropriate to deem any party to be the drafter of this AGREEMENT; and, therefore, no presumption for or against validity or as to any interpretation hereof, based upon the identity of the drafter, shall be applicable in interpreting or enforcing this AGREEMENT.

21. ASSISTANCE OF COUNSEL. Each party to this AGREEMENT warrants to each other party as follows:
a. That each party either had the assistance of counsel or had counsel available to it, in the negotiation for, and execution of, this AGREEMENT, and all related documents; and,
b. That each party has lawfully authorized the execution of this AGREEMENT.

PAGE 306 of 623
Maintenance Contract $30k or More
-9-
Revised-7.2025
h. Primary/noncontributing. Coverage provided by CONTRACTOR shall be primary and any insurance or self-insurance procured or maintained by CITY shall not be required to contribute with it. The limits of insurance required herein may be satisfied by a combination of primary and umbrella or excess insurance.

CITY’S rights of enforcement. In the event any policy of insurance required under this AGREEMENT does not comply with these specifications or is canceled and not replaced, CITY has the right but not the duty to obtain the insurance it deems necessary, and any premium paid by CITY will be promptly reimbursed by

Enforcement of contract provisions (non estoppel).

CONTRACTOR acknowledges and agrees that any actual or alleged failure on the part of the CITY to inform CONTRACTOR of noncompliance with any requirement imposes no additional obligations on the CITY nor does it waive any rights hereunder.
m. Requirements not limiting. Requirements of specific coverage features or limits contained in this Section are not intended as a limitation on coverage, limits or other requirements, or a waiver of any coverage normally provided by any insurance. Specific PAGE 307 of 623
Maintenance Contract $30k or More
-10-
Revised-7.2025
reference to a given coverage feature is for purposes of clarification only as it pertains to a given issue and is not intended by any party or insured to be all inclusive, or to the exclusion of other coverage, or a waiver of any type. If the CONTRACTOR maintains higher limits than the minimums shown above, the CITY requires and shall be entitled to coverage for the higher limits maintained by the CONTRACTOR. Any available insurance proceeds in excess of the specified minimum limits of insurance and coverage shall be available to the CITY.
n. Notice of cancellation. CONTRACTOR agrees to oblige its insurance agent or broker and insurers to provide the CITY with a thirty (30) day notice of cancellation (except for nonpayment for which a ten (10) day notice is required) or nonrenewal of coverage for each required coverage. If any of the CONTRACTOR’S insurers are unwilling to provide such notice, then CONTRACTOR shall have the responsibility of notifying the CITY immediately in the event of CONTRACTOR’S failure to renew any of the required insurance coverages, or insurer’s cancellation or non-renewal.
o. Additional insured status. General liability, automobile liability, and umbrella/excess liability insurance policies shall provide or be endorsed to provide that CITY and its officers, officials, employees, agents, and volunteers shall be additional insureds under such policies.
p. Prohibition of undisclosed coverage limitations. None of the coverages required herein will be in compliance with these requirements if they include any limiting endorsement of any kind that has not been first submitted to CITY and approved of in writing. q. Separation of insureds. A severability of interests provision must apply for all additional insureds ensuring that CONTRACTOR’S insurance shall apply separately to each insured against whom claim is made or suit is brought, except with respect to the insurer’s limits of liability. The policy(ies) shall not contain any cross-liability exclusions.
r. Pass through clause. CONTRACTOR agrees to ensure that its subconsultants, subcontractors, and any other party who is brought onto or involved in the project/service by CONTRACTOR
(hereinafter collectively “Subcontractor”), provide the same minimum insurance coverage and endorsements required of CONTRACTOR under this AGREEMENT. CONTRACTOR agrees to monitor and
review all such coverage and assumes all responsibility for ensuring that such coverage is provided in conformity with the requirements PAGE 308 of 623
Maintenance Contract $30k or More
-11-
Revised-7.2025
of this section. However, in the event CONTRACTOR’S
Subcontractor cannot comply with this requirement, which proof must be submitted to the CITY, CONTRACTOR may still be able to utilize the Subcontractor provided CONTRACTOR shall be required to ensure that its Subcontractor provide and maintain insurance coverage and endorsements sufficient to the specific risk of exposure involved with Subcontractor’s scope of work and services, with limits less than required of the CONTRACTOR, but in all other terms consistent with the CONTRACTOR’S requirements under this AGREEMENT. This provision does not relieve the CONTRACTOR of its contractual obligations under the AGREEMENT and/or limit its liability to the amount of insurance coverage provided by its subcontractors. This provision is intended solely to provide CONTRACTOR with the ability to utilize a Subcontractor who may be otherwise qualified to perform the work or services but may not carry the same insurance limits as required of the CONTRACTOR under this AGREEMENT given the limited scope of work or services provided by the subcontractor.

ATTACHMENT A - SCOPE OF WORK

1. Scope of Work
The Scope of Work is described as follows.

2. Background
The Orange County Transportation Authority’s (OCTA) Environmental Cleanup Program (ECP) provides a two percent allocation of annual gross Measure M2 (M2) revenues to improve overall water quality in Orange County from transportation-related pollution. The ECP competitive funds can be used to implement water quality improvement projects addressing pollutants originating from or conveyed through transportation systems. These funds will assist Orange County cities and the County of Orange in meeting federal Clean Water Act standards for urban runoff through the purchase and installation of recognized structural best management practices (BMPs). Third parties such as public water and wastewater agencies, environmental advocacy organizations, and homeowners associations may also nominate projects through a municipality that is willing and able to take responsibility for carrying out and maintaining the project.

3. Description of Project
In concert with the M2 Grant Program, this Scope of Work is designed to assemble a panel of Contractors to achieve economies of scale on a list of fixed unit prices for the purchase and installation of equipment and devices designed to remove litter, debris, and other water quality pollutants, herein referred to as “Stormwater Treatment Devices.” Selected Contractors will be part of a Master Agreement with the County of Orange that will allow municipalities to select from a listing of Contractors to provide, supply, fabricate, construct, deliver, and install Stormwater Treatment Devices. Municipalities wishing to use this Contract may purchase BMPs with M2 grant monies or any other funding source.

Accordingly, the goal of this Contract is to achieve strategic savings that would benefit the County and OCTA to act as the purchasing and contract administrators for M2 grant-eligible entities. Awarded ECP entities are not obligated to utilize the selected Contractors. Rather, this process is intended to provide a mechanism for reduced rates for equipment and its installation for Orange County municipalities, including those implementing projects with M2 funding. In addition, if a local agency utilizes this Contract, a separate agreement, city council resolution, or other protocol may be necessary with the selected Contractor(s). The eligible qualifications are discussed below.

4. Eligibility Qualifications
Stormwater Treatment Devices must be capable of handling flows from a design storm of 0.2-inches/hour.

The hydrologic method to be used to calculate the flow associated with LID and water quality design storm flow is:

Frequired = C × I × A
Where Frequired = Flow capacity (cubic feet/sec); C = runoff coefficient (ranges from 0 to 1); I = 0.2 inches/hour; and A = tributary area (acres).

Trash and Debris Capture Devices

Page 27 of 35 ends

File No. 2736403
Treatment devices should also be able to operate in a hydraulic surcharge condition (defined as a condition that exceeds the design discharge) without releasing stored pollutants to the receiving water. Stormwater Treatment Devices which meet this definition and would be eligible for consideration are:

A. Hydrodynamic Separation and Gross Solids Removal Devices Hydrodynamic separators are flow-through structures with a settling or separation unit to remove sediments and other pollutants and are widely used in stormwater treatment. No outside power source is required, because the energy of the flowing water allows the sediments to efficiently separate. Depending on the type of unit, this separation may be by means of centrifugal force or indirect filtration.

Gross Solids Removal Devices (either linear radial or inclined screen) are structural best management practices designed to remove trash, vegetative material, and other particles of relatively large, gross size from stormwater runoff.

B. Catch Basin Inserts
Catch basin inserts are designed to remove oil and grease, trash, debris, and sediment and improve the efficiency of catch basins. Some inserts are designed to drop directly into existing catch basins, while others may require retrofit construction. Several varieties of catch basin inserts exist for filtering runoff.

C. Automatic Retractable Screens
Automatic retractable screens are mounted inside a storm drain inlet and are designed to remain closed to capture debris during the dry season. During storm events, the screens retract, allowing heavy flows to enter the storm drain.

D. Cartridge Filter-type Control Devices
Cartridge filter–type controls typically consist of a series of vertical filters contained in a vault or catch basin that provide treatment through filtration and sedimentation.

E. Biological Treatment Devices
Bioretention devices include raingardens, swales, and filter strips; all use plants and substrate to detain and filter stormwater to reduce excessive runoff from roads and paved surfaces, and provide opportunities for enhancing natural landscape and biodiversity elements in the urban environment.

F. In-line Trash and Debris Capture Devices (Trash Booms and Trash Nets) Trash booms and nets are designed to assist in the control, containment and recovery of floating trash, debris, timber, urban waste or aquatic plants. Typically built as floating structures, these devices are designed to control pollution along the surface of the water.

G. New, Emerging, or Alternative Trash and Debris Devices Upon request, the Contractor shall submit supplemental proposals for new, emerging, or alternative trash and debris removal devices reasonably related to the categories listed within Attachment A Section 4 and to meet the intent of Attachment A Section 3. Contractor must obtain written approval from the County and/or local agency designee prior to commencing any work for these new, emerging, or alternative trash and debris removal devices, which may include but not be limited to design, fabrication, and/or installation of these devices not already included in this scope of work. Upon completion of any work related to these devices, the local agency designee and Contractor will inspect the finished product at no Docusign Envelope ID: 66B81198-7190-4167-9EE0-14B72F061C12 PAGE 342 of 623

READING) AN ORDINANCE OF THE SAN MARINO CITY
COUNCIL AMENDING SECTION 2.05.01 OF THE

MUNICIPAL CODE TO RESTATE INDIVIDUALS EXEMPT
FROM THE CITY’S CLASSIFIED SERVICE

STRATEGIC PLAN CRITICAL SUCCESS FACTORS
Fiscally Responsible and Transparent City Government
Efficient, Responsive, and Effective City Services

BACKGROUND
At the September 10, 2025, City Council meeting, the Council unanimously introduced Ordinance No. O-25-1422 for a first reading. The Ordinance is attached for the Council’s consideration and adoption.

DISCUSSION
Currently, the City does not define which positions and offices are exempt from the Classified Service in its Municipal Code. Rather, the previous version for the Personnel Rules and Regulations stated that “All employees of the City of San Marino except those specified as unclassified or as management personnel” are in the City’s Classified Service. The new version of the Personnel Rules and Regulations, as adopted in Resolution No. R-25-24 (Attachment 1), provides clarity and specifically lists the positions and offices that are exempt from the Classified Service. This list does not change which positions and offices are exempt from the Classified Service, rather it is a mirror reflection of the City’s ongoing practice, consistent with the previous Gretchen Shepherd Romey, Mayor
Tony Chou, Vice Mayor
Hunter Chang, Council Member
John Chou, Council Member
Calvin Lo, Council Member
PAGE 353 of 623
definition in its prior version of the Personnel Rules and Regulations regarding the same.

However, to avoid ambiguity and confusion while implementing the newly revised Rules and any future revisions to the Personnel Rules and Regulations, staff recommends revising the Municipal Code, Chapter II, Article 5, Section

2.05.01 to clearly outline, in the Municipal Code, which positions and offices have been and are currently exempt from the Classified Service.

FISCAL IMPACT & PROCUREMENT REVIEW
There is no anticipated fiscal impact from the attached ordinance.

LEGAL REVIEW
The City Attorney's office has reviewed and approved as to form.

RECOMMENDATION
Staff recommends the Council adopt Ordinance No. O-25-1422, an Ordinance of the San Marino City Council amending Section 2.05.01 of the Municipal Code to clarify which offices, positions, and employments are exempt from the City’s Classified Service. If the City Council concurs with staff’s recommendation an appropriate motion would be:
“I move to approve Ordinance No. O-25-1422, an Ordinance of the San Marino City Council amending Section 2.05.01 of the Municipal Code to restate individuals exempt from the City’s Classified Service.”

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF
SAN MARINO, CALIFORNIA, AMENDING SECTION 2.05.01

OF THE MUNICIPAL CODE TO RESTATE INDIVIDUALS
EXEMPT FROM THE CITY’S CLASSIFIED SERVICE
WHEREAS, the City’s current personnel rules and regulations define the Classified Service as “All employees of the City of San Marino except those specified as unclassified or as management personnel;”
WHEREAS, such definition is unintentionally vague and the City is clarifying the exemption from Classified Service in its newly drafted Personnel Rules and Regulations (“Rules”) as presented to the City Council in Resolution No. R-25-24 and WHEREAS, to formalize the City’s past and present practice as to which individuals are exempt from the Classified Service, the City is amending the Municipal Code as provided in Section 2 of this Ordinance.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF SAN MARINO DOES ORDAIN AS FOLLOWS:

SECTION 1. Recitals. The City Council of the City finds and declares that the recitals set forth above are true and correct and are incorporated herein by this reference.

SECTION 2. Amendment of the City of San Marino Municipal Code Section 2.05.01.

Chapter II, Article 5, Section 2.05.01 is amended to add subsection “E” to read as follows; “E. Classified Service means the offices, positions and employments in the service of the City except the following: 1) Elected and appointed officers; 2) Members of appointed boards, commissions and committees; 3) Persons engaged under contract to supply expert, professional, or technical services for a definite period of time; 4) Volunteer personnel; 5) City Manager; 6) City Attorney; 7) Department Heads; and 8) Employees serving in hourly, temporary, provisional, parttime, or seasonal appointments.” SECTION 3.

BACKGROUND
In May 2006, the State Water Resources Control Board (SWRCB) adopted Order No. 2006-0003-DWQ, titled Statewide General Waste Discharge Requirements (WDR) for Sanitary Sewer Systems. This Order established regulatory requirements for public wastewater collection systems with the primary goal of reducing the frequency and volume of sanitary sewer overflows statewide. Under the WDR, all public agencies in California that own or operate more than one (1) mile of sewer pipeline are subject to regulation and are required to develop a Sewer System Management Plan (SSMP) in accordance with the Order’s guidelines. The SSMP serves as a comprehensive guide for the effective operation, maintenance and long-term planning of the City’s sanitary sewer collection system.

In December 2022, the SWRCB adopted Order No. 2022-0103-DWQ, which updates and supersedes the previous Order No. 2006-0003-DWQ and all amendments thereafter. As with the previous Order, it continues to mandate the adoption and maintenance of an SSMP as a central planning and compliance tool.

The City’s SSMP was last updated in 2019. In accordance with State requirements, the document must be updated at least once every six (6) years to remain compliant with current regulations and operational standards. City staff, in collaboration with Dudek, the City’s on-call stormwater and wastewater engineering consultant, prepared the 2025 SSMP Update to ensure the plan remains current, compliant and aligned with industry best practices.

To support the long-term sustainability of its sewer system, the City Council recently adopted sewer service charges for the first time. These charges provide a dedicated funding source for ongoing maintenance, rehabilitation, and capital improvements, reinforcing the City’s commitment to responsible infrastructure management and directly aligns with the goals and implementation strategies outlined in the SSMP.

DISCUSSION
The SSMP is a critical document that outlines the City’s approach to managing its wastewater collection system. It includes key components required by the SWRCB, including a Spill Emergency Response Plan (SERP) which details the City’s procedures for responding to sanitary sewer overflows (SSOs) and other emergency events. Beyond emergency response, effective management of the City’s sanitary sewer collection system includes:
• Implementing best practices to manage, operate, and maintain all components of the system, including sewer mains, lift stations and manholes
• Conducting routine maintenance, inspections, and condition assessments to ensure system reliability
• Maintaining adequate capacity to handle peak flows and minimize the risk and impact of sanitary sewer overflows (SSOs)
• Planning and prioritizing capital improvements to support long-term infrastructure sustainability
The primary goal of the SSMP is to protect water quality, reduce or eliminate preventable sanitary sewer overflows (SSOs), and safeguard public health and the environment. In addition to serving as a guide for best management practices, the adoption and recertification of the 2025 SSMP is required to PAGE 358 of 623
maintain compliance with State regulations. The updated SSMP reflects current regulatory standards and City operations and will serve as a working document to support staff in effective management of the sanitary sewer collection system over the coming years. In accordance with WDR requirements, the final 2025 SSMP must be formally approved by the City Council to complete the certification process.

FISCAL IMPACT & PROCUREMENT REVIEW
The FY 2025-26 budget includes $40,000 in Account No. 101-44-4104-0000 for contract engineering including the update of the SSMP. There are sufficient funds to complete this work.

There is no direct fiscal impact associated with the approval of the updated SSMP. Implementation of the Plan’s recommendations will be addressed through the City’s Capital Improvement Program and annual budget process.

Procurement review is not applicable.

LEGAL REVIEW
The City Attorney's office has reviewed and approved as to form.

RECOMMENDATION
Staff recommends the City Council approve Resolution R-25-30 adopting the 2025 Sewer System Management Plan (SSMP) Update and authorizing the Legally Responsible Official to certify and submit the SSMP to the State Water Resources Control Board. If Council concurs with staff’s recommendation, an appropriate motion would be:
“I move to approve Resolution R-25-30 adopting the updated Sewer System Management Plan (SSMP) in compliance with State Water Resources Control Board Order No. 2022-0103-DWQ and authorizing the Legally Responsible Official to certify and submit the SSMP to the California State Water Resources Control Board.”

City of San Marino Sewer System Management Plan Page viii

INTENTIONALLY LEFT BLANK
PAGE 371 of 623
City of San Marino Sewer System Management Plan Page ix Purpose and Background
In December 2022, the State of California’s Water Resources Control Board (SWRCB) adopted Order Number WQ 2022-0103-DWQ that updated General WDRs for sanitary sewer systems designed to convey sewage greater than one (1) mile in length. The order became effective on June 5, 2023. This order supersedes the previous Order Number 2006-0003-DWQ and all amendments thereafter (i.e., Order No. WQ 2013-0058-EXEC). The WDR requires that all enrolled agencies develop a Sewer System Management Plan (SSMP) that describes the activities of the enrollee in managing, operating, and maintaining their sanitary sewer collection system. The purpose of the Order is to prevent sanitary sewer spills and to provide a plan and schedule for measures to be implemented for spill prevention including measures to effectively clean up and report spills. A copy of the reissued 2022 WDR is included in Appendix A.

The reissued WDR includes directives for owners and operators of sanitary sewer systems to demonstrate adequate and efficient management, operation, and maintenance of the sanitary sewer system. Generally, the WDR requires that:

In the event of a spill, all feasible steps are taken to control the released volume and prevent untreated wastewater from entering storm drains, creeks, etc.

If a spill occurs, it must be reported to the SWRCB using California Integrated Water Quality System (CIWQS), the online reporting system developed by the SWRCB.

An SSMP with all mandatory elements be developed and approved by the governing body that owns or is responsible for the operation of the sanitary sewer system. The SSMP must include provisions to provide proper and efficient management, operation, and maintenance of the sanitary sewer system.

Spills often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygendemanding organic compounds, oil and grease and other pollutants. Spills may cause a public nuisance and/or a public health hazard particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. Spills may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters.

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), or excessive infiltration and inflow (I/I) which affect the likelihood of a spill. A proactive approach that requires agencies to ensure a system-wide operation, maintenance, and management plan is in place that will reduce the number and frequency of spills within the state.

This approach will in turn decrease the risk to human health and the environment caused by spills.

Element 1: SSMP Goal & Introduction
City of San Marino Sewer System Management Plan Page 2
SSMP Update by the City Council in 2025. The SSMP has been audited in 2024 in compliance with the State Water Resources Control Board’s regulations.

The WDR requires that the SSMP be updated and approved by the agency’s elected governing body every six (6) years after the date of its last Plan Update due date. In addition, the City is to conduct an internal audit every three (3) years of the SSMP in order to assess the City’s progress towards meeting the goals, objectives and requirements set forth in the SSMP. The due dates for the City’s SSMP and SSMP audits can be found here using the City’s WDID (4SSO10428): https://www.waterboards.ca.gov/water_issues/programs/sso/lookup/.

The SSMP along with all references in the document, self-audits, and the adoption documents approved by City Council will be kept on file at City offices, the City’s website and an entry will be made in the California Integrated Water Quality System (CIWQS) database when SSMP updates and audits are completed.

The City has a goal to effectively implement the SSMP, ensuring regular cleaning, CCTV inspections, condition assessments, and rehabilitation to properly maintain the sewer system.

3.2.2 Storm Water Agency Collaboration
The maintenance staff for the City’s sewer and storm systems are under the same Street Maintenance Division at the City and therefore all staff are well informed of both the sewer and storm drain systems. This enables a unified collaboration and flow of information between staff members. Communication and training with all staff ensure they know their part in responding to spills and recognizing areas at risk, develop strategies in containing and preventing spills, and reduce risks of cross contamination. Additionally, the City’s personnel maintain knowledge of the locations of storm water collection facilities that are nearby sewer facilities.

Installation of sewer and storm water facilities are coordinated to prevent unintentional cross connections. To ensure that cross-connections between the City’s sanitary sewer and storm drain systems do not occur, the City maintains records of the alignments of both systems and when they were constructed.

No connections to either system are allowed without a permit being first obtained from the City’s Public Works Department.

All connections to either system are inspected by the Street Foreman and the Public Works Manager to ensure that the connection is made in accordance with established standards.

3.2.3 Proper Design and Construction of Sewers and Connections Regulations pertaining to the design, construction, and inspection of private sewer systems, building sewers, and connections are included in Chapter 13 of the City’s Municipal Code.

Permit Required - A permit is required prior to construction of any private sewage disposal system (plumbing code).

A permit is also required prior to constructing a building or lateral sewer or connecting to a public sewer as discussed in Chapter 16 of the City’s Municipal Code. The permit application may include review of plans and specifications by the City.
• Sections 16.02.02 & 16.04.01 requires a permit for any construction or excavation in the public right of way

Maintenance Program
This chapter describes the City’s ability to properly manage, operate, and maintain all parts of the sanitary sewer system owned and operated by the City, and that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities.

Requirements:

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

4.1. Updated Map of Sanitary Sewer System: An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries.

4.2. Preventive Operation and Maintenance Activities: A scheduling system and a data collection system for preventive operation and maintenance activities conducted by staff and contractors.

The scheduling system must include:
• Inspection and maintenance activities;
• Higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems;
• Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes. The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.

4.3. Training: In-house and external training provided on a regular basis for sanitary sewer system operations and maintenance staff and contractors. The training must cover:
• The requirements of the General Order;
• The Enrollee’s Spill Emergency Response Plan procedures and practice drills; • Skilled estimation of spill volume for field operators; and • Electronic CIWQS reporting procedures for staff submitting data.

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

PAGE 388 of 623
Element 4: Operation and Maintenance Program
City of San Marino Sewer System Management Plan Page 14

4.1 Updated Map of Sanitary Sewer System
The City has created a comprehensive, customized, electronic based Geographic Information System (GIS) sewer collection system map, showing all pipeline segments and manholes within the City’s jurisdictional boundary. Both digital and hard copy versions are maintained, with printed maps stored at the Parks & Public Works Department (PPWD). Additionally, each maintenance vehicle is equipped with printed maps showing the sewer collection system, including pipes, manholes, and pump stations.

Currently, the City does not have a formal process for regularly updating the GIS when new assets are added or existing ones are replaced. Over the past four years, there have been minimal changes to the sewer system assets.

The City will prioritize maintaining an up-to-date GIS by ensuring timely updates when assets are added, modified, or abandoned.

Maintenance crews utilize both GIS and hard copy maps for accessing sewer line information. The City’s current sewer maintenance contractor, Premier Pipe, documents maintenance activities such as repairs, cleanings, and work order history using WinCan software. In July 2025, during the renewal of its contract with Premier Pipe, the City gained full access to WinCan, allowing staff to directly view detailed work order histories. City personnel will receive training on the WinCan platform to ensure effective use and understanding.

The City is responsible for maintaining the stormwater system and does have access to maps of the nearby storm water inlets and pipelines, as these are City-owned facilities.

The City will provide State and Regional Water Board staff with access to the map(s) through submitting the sewer geodatabase to the State and Regional Water Boards as well as including the map within this SSMP Update, which will be submitted to CIWQS once a year. An updated map of the sewer collection system is included in Appendix E.

4.2 Preventive Operation and Maintenance Activities
The City currently relies on their contractors for preventive operation and maintenance activities. This includes periodic cleaning, regular CCTV inspection, and chemical dosing.

4.2.1 Sewer Cleaning & CCTV Inspection
The City currently contracts Premier Pipe to perform preventative maintenance on the sewer collection system.

Under this agreement, the contractor cleans approximately half of the system each year and cleans Enhanced Maintenance Areas (EMAs) on a semiannual basis (every six months). Additionally, Premier Pipe conducts CCTV inspections of half the entire system every two years. Starting in July 2025, the City gained direct access to the contractor’s Wincan software, allowing staff to retrieve CCTV inspection data independently, without needing to request it from the contractor.

When issues are identified during CCTV inspections, they are evaluated and scored using Pipeline Assessment Certification Program (PACP) standards. These scores are stored in the City’s database and used to guide future wastewater condition assessments and updates to the CIP list.

The City plans on implementing a formal procedure for managing Grade 5 pipelines, which are identified through CCTV inspections as having severe structural defects. These pipelines pose a high risk of failure due to the extent of the damage, making timely and consistent action essential. Pipes classified as Grade 5, indicating severe defects, are prioritized for timely repair to prevent potential failure. Moving forward, upon identification of a Grade PAGE 389 of 623
Element 4: Operation and Maintenance Program
City of San Marino Sewer System Management Plan Page 15 5 pipeline, the City will assign a repair deadline ranging from six months to one year. Coordination with Premier Pipe or another designated contractor will ensure that repairs are completed within this timeframe. All Grade 5 pipelines will be maintained in a separate database and monitored regularly to track progress and ensure accountability.

When severe pipeline defects are identified and require emergency repair, Premier Pipe immediately addresses and fixes these defects.

In addition to routine maintenance and emergency repairs, Premier Pipe is responsible for root treatment and emergency repairs within the sewer system. Although the City does not currently track the annual footage of pipeline treated for roots, this service is performed as needed. The contractor, Golden Bell, also applies chemical treatments to manholes to control cockroach infestations, treating approximately half of the City’s manholes each year.

4.2.2 Lift Station Maintenance
The City’s Operations staff does weekly monitoring of the City’s pump stations to assure that they are operating properly. This team consists of four staff members, organized into two crews. All three of the City’s sewer lift stations are maintained through an ongoing contract with Gemini to perform maintenance on all three lift stations, each of which is equipped with a backup generator to ensure continued operation during power outages. Gemini is available 24 hours a day to service the pump stations as needed.

4.2.3 Odor Control
The City has received approximately five odor complaints annually, most of which are investigated and addressed.

Investigations have found that odors typically originate from County trunk lines, especially during extended hot weather.

Upon receiving a complaint, operations staff inspect the line. If a blockage is found, the contractor is called to flush and CCTV inspect the line. Any defects such as sags, cracks, or offsets are flagged and are added to the permanent repair list.

4.2.4 Corrosion Control
Over 87 percent of the pipe material in the City’s collection system is vitrified clay pipe (VCP), which is inert and does not need corrosion control. The remaining portion of the collection system is concrete pipe, cast iron pipe (CIP), or ductile iron pipe (DIP) which is not inert and does need corrosion control. To prevent corrosion, the City undertakes numerous relining projects as part of the Capital Improvement Program.

4.2.5 Investigation of Customer Complaints
The City promptly addresses customer complaints about the sewer system, which are typically related to sewer back-ups. The contractor responds immediately by conducting CCTV inspections of the lines and making necessary repairs to the affected sections or manholes. This response involves assessing the complaint and resolving the issue efficiently.

4.2.6 Data Collection
The City’s contractor, Premier Pipe, currently documents their cleanings and CCTV inspections electronically using WinCan software. With the City now having full access to WinCan, staff can review digital records of these activities.

PAGE 390 of 623
Element 4: Operation and Maintenance Program
City of San Marino Sewer System Management Plan Page 16 This access will also support the City in monitoring system deficiencies by identifying recurring issues based on complaints, field inspections, and CCTV inspection results.

4.3 Training
The City utilizes a variety of training methods for its staff, including in-house classes, on-the-job training, and conferences. The PPWD conducts weekly tailgate meeting, monthly safety meetings, annual SERP trainings, and provides training manuals for various O&M activities. To ensure the sewer system is properly maintained, the City will continuously review its training program. The City is planning on performing annual meetings to review sections of the SSMP. The City will continue to implement training on the Spill Emergency Response Plan procedures and practice drills, skilled estimation of spill volume for field operators, and electronic CIWQS reporting procedures for staff submitting data.

Currently, the City’s active CIP contractor does not conduct formal SERP or SSMP training. The City plans to include formal SERP and SSMP training to its renewed contract with the active contractor.

The City is committed to all trainings being documented and the records kept readily accessible.

4.4 Equipment Inventory
The City’s contractors, Premier Pipe and Gemini, are responsible for maintaining their equipment in proper working condition and ensuring the availability of necessary backup supplies, including spill response equipment. Each contractor is also responsible for maintaining an up-to-date inventory.

5. City personnel involved in the Sewer Spill Response shall forward a report of the incident to their department head. The report shall detail the cause of the spill, actions taken to limit the spill, damage caused by the spill and action taken to remove the waste.

6. The Public Works Division Manager, or his/her designee, shall report the spill event to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services).

Section 6.2 of this Spill Emergency Response Plan details the chain of communication for reporting spills and contact numbers for these points of contact.

Pre-planned coordination and collaboration with the City’s stormwater staff will be implemented prior, during, and after a spill event.

6.7 Initial Spill Response

6.7.1 Site Assessment
City staff shall investigate and assess the site conditions where the spill occurred using the following methods:

1. Determine the Category of the spill. (Refer to Section 6.9, Spill Categories)

2. Determine the size and extent of the spill.

3. Determine any potential hazards, such as vehicle and pedestrian traffic.

4. Identify receiving water that may be impacted by spill.

5. Document and record all pertinent information of the spill.

6. Implement traffic control measures as needed per the WATCH Manual. Should you need traffic or crowd control assistance, call police dispatch at (626) 300-0720 to assist with street closure, traffic diversion, or crowd control.

7. Post warning signs and block contaminated areas with yellow caution tape and/or barricades if spill poses a public threat or it has or will reach Waters of the State.

8. If spill location calls for it, the Public Works Manager will contact the Public Works Director to arrange for a partial activation of the Emergency Operations Center (EOC).

6.7.2 Containment Procedures
Containment of the spill is the top priority. City staff respond initially to spill calls and perform spill containment until the City’s pipeline contractor arrives to correct blockages, perform spill recovery and any necessary emergency repairs. The City’s current pipeline contractor with contact information are listed in this section by the City and are noted below in Table 6.2:

Contractor Premier Pipe, Inc (909) 297-4808
PAGE 397 of 623
Element 6: Spill Emergency Response Plan
City of San Marino Sewer System Management Plan Page 23 The City’s crew will attempt to keep the spill in as small an area as possible. If reasonable, the crew should attempt to keep the spill in the street and out of the storm drain or other surface water bodies. To ensure the spill is contained, the crew will use the following methods:

1. Contain the spill immediately. Contain sewage on the ground using a manmade berm if applicable.

2. Isolate, contain, and/or divert sewage flow from any open channels and storm drain structures using sandbags, inflatable dams, or soil barriers. Sandbags or absorbent material can be used around the spill to collect the sewage and prevent it from spreading.

3. Block the storm drain openings or divert flow with sandbags and plastic sheets, which are available at several locations around the City. If reasonable, keep the flow contained on the street. Pay special attention to blocking storm drain inlets of any kind, both downstream and upstream of the spill. Setup traffic control per the WATCH Manual. Should you need traffic or crowd control assistance, call police dispatch at (626) 300-0720.

4. Should the spill take place in an area not normally accessible to the public (i.e. field, etc.) the crew will use any reasonable means to pool the flow in that area for recovery.

5. Capture the spill.
a. If necessary, berm flow and start pumping into the closest clear and flowing manhole. b. Contact the Public Works Manager at 626-300-0793. If he/she cannot be reached, the Foreman will contact the Public Works Director at 626-300-0787. c. Evaluate the sewer system spill rate. The most senior employee on scene will evaluate the spill rate.

6. Determine the source and/or cause of the spill (i.e., evaluate type and amount of debris, illegal activities, etc.). City staff may need to observe downstream manholes to establish the location of the cause of the spill such as a blockage.

7. Clear the obstruction and restore flow.
i. Restore system flow by hydro jetting, rodding, open cut excavating, or any other means to clear the blockage or failure point.
ii. If necessary, City Staff should set up a hydro jetter downstream of the blockage and jet upstream from a clear manhole.
b. Capture as much of the material causing the blockage as possible. c. If unable to relieve the blockage, request immediate assistance from additional staff and appropriate equipment.
d. If still unable to clear the blockage, request immediate assistance with the establishment of bypass pumping and CCTV support to determine the problem. e. If engineering consultation is necessary, contact the Public Works Manager (or Public Works Director if he/she cannot be reached). He/she shall initiate an emergency work order to the City’s on-call contractor to repair the pipe.
f. Ensure the downstream manholes are clear and flowing.

8. Should the flow be too much to be contained in the street and is identified as a danger to the public the crew will allow the flow to enter the storm drain or catch basin. The crew will plug upstream and downstream portions of impacted storm drains or catch basins and recover it from that point.

9. Upon determining and correcting the source and/or cause of the spill, a sample of the sewage may be taken as evidence for possible analysis.

10. All sewage shall be captured and discharged into the closest clear and flowing manhole. Any contaminated materials unfit for the sewer and likely to cause blockages shall be transported to a local landfill for ultimate disposal. See Section 6.8 for treatment in dry or wet weather conditions and collection instructions.

11. Estimate volume of the spill as detailed in Section 6.14.2.

PAGE 398 of 623
Element 6: Spill Emergency Response Plan
City of San Marino Sewer System Management Plan Page 24

12. Notify regulatory agencies about the spill and follow any additional instructions they may have.

6.7.3 Sewer Bypassing
If the spill involves damage to a pipeline and a by-pass is necessary:

1. By-pass action is to be administered, as soon as conditions safely allow, by City personnel at the location where the damaged pipeline occurs.

2. Place appropriate pumps and hoses to keep sewage in the sewerline. If additional pumps and piping or hoses are required to conduct a by-pass, a list of equipment rental companies and contractors with contact information will be developed and listed in this section by the City. The current equipment rental company and active contractor is listed below in Table 6.3:

Table 6.3: Equipment Rental Companies and Contractors for Spill Response Equipment Rental Stemar Equipment (213) 625-0185
Contractor Premier Pipe, Inc (909) 297-4808

3. Perform repairs to the damaged sewerline as soon as conditions safely allow and as resources are available.

4. If engineering consultation is necessary, the City has a list of On-Call Engineering Firms. Table 6.4 lists the City’s On-Call General Civil Engineering Firm(s):

6.8 Recovery and Clean-Up (Mitigation)

1. If the spill occurs during dry weather conditions:
a. Once the spill has been eliminated, use rakes, brooms, and other applicable tools to scrape up and remove all solids and debris.
b. Any remaining standing sewage shall be vacuum pumped and discharged into the closest manhole (ensure it is clear and flowing).
c. Any contaminated soil shall have free standing sewage or water vacuumed up, lime applied, allowed to dry, and then removed (as necessary) by means of heavy equipment and transported to a local landfill for ultimate disposal.
d. Any contaminated structures such as streets, sidewalks, buildings, etc., shall be disinfected by pressure spraying with a 25 ppm sodium hypochlorite (liquid bleach) solution. After providing a contact time of 1 hour, the disinfected structures shall be rinsed with city water, and the wash water vacuumed and disposed of into the closest manhole (ensure it is clear and flowing). i. BEFORE PRESSURE WASHING CONTAMINATED AREA, ALL CONTAMINATED MATERIALS PAGE 399 of 623
Element 6: Spill Emergency Response Plan
City of San Marino Sewer System Management Plan Page 25 AND CONTAMINATED SOIL MUST BE REMOVED AND CATCH BASINS MUST BE BLOCKED.

VACUUM MUST BE READY TO PICK UP WATER FROM PRESSURE WASHING. No water, sewage, bleach, or containment materials are to be washed into the storm drain system. ii. If the spill occurred in a heavily populated area or is within 100 feet of surface water, bleach should not be used.
e. If wastewater enters the storm drain or catch basin, a vactor truck may be used to vacuum the sump at a downstream catch basin, while clean water is used to flush the curb, gutter, and pipe upstream.
f. Leave the area as clean as possible picking up rags, papers, etc. Emphasis should be placed on removing all materials that are on or around the contaminated area. g. Restore the area to its original condition, or as close as possible. h. Documentation and recording of all pertinent information of the spill shall be completed prior to leaving the site.

2. If the spill occurs during wet weather conditions:
a. Once the spill has been eliminated, use rakes, brooms, and other applicable tools to scrape up and remove all solids and debris.
b. Any remaining standing sewage shall be vacuum pumped and discharged into the closest clear and flowing manhole.
c. Any contaminated soil shall have free standing sewage or water vacuumed up, lime applied, allowed to either dry or sit for an hour, and then removed (as necessary) by means of heavy equipment and transported to a local landfill for ultimate disposal. i. Omit lime application during heavy storm events with heavy runoff, where the surface water cannot be contained.
d. Any contaminated structures such as streets, sidewalks, buildings, etc., shall be cleaned with clean water. Avoid using bleach during wet weather as the bleach can harm the environment. e. If wastewater enters the storm drain or catch basin, a vactor truck may be used to vacuum the sump at a downstream catch basin, while clean water is used to flush the curb, gutter, and pipe upstream.
f. Leave the area as clean as possible picking up rags, papers, etc. Emphasis should be placed on removing all materials that are on or around the contaminated area. g. Restore the area to its original condition, or as close as possible. h. Documentation and recording of all pertinent information of the spill shall be completed prior to leaving the site.
i. If a spill is caused by lack of capacity during wet weather conditions, document the storm event and forward information to the Public Works Manager.

6.9 Spill Categories
Per the Reissued WDR, there are now four (4) categories of spills. Individual spill notification, monitoring and reporting must be in accordance with the following spill categories:

PAGE 400 of 623
Element 6: Spill Emergency Response Plan
City of San Marino Sewer System Management Plan Page 26

6.9.1 Category 1 Spill
A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under this General Order that results in a discharge to:
• A surface water, including a surface water body that contains no flow or volume of water; or • A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly.

Note: Any spill volume not recovered from a drainage conveyance system is considered a discharge to surface water, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility.

A spill from a City-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the City will report all Category 1 spills per Appendices A and B of this document.

6.9.2 Category 2 Spill
A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.

A spill of 1,000 gallons or greater that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system, is a Category 2 spill.

6.9.3 Category 3 Spill
A Category 3 spill is a spill of equal to or greater than 50 gallons and less than 1,000 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.

A spill of equal to or greater than 50 gallons and less than 1,000 gallons, that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 3 spill.

6.9.4 Category 4 Spill
A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.

A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 4 spill.

City of San Marino Sewer System Management Plan Page 37 7 Sewer Pipe Blockage
Control Program
This chapter discusses the City’s sewer pipe blockage control measures, including identification of problem areas, focused cleaning, and source control.

Requirements:

D.7. SEWER PIPE BLOCKAGE CONTROL PROGRAM: The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed. The procedures must include, at minimum:
• An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe-blocking substances;
• A plan and schedule for the disposal of pipe-blocking substances generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of substances generated within a sanitary sewer system service area; • The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, recordkeeping and reporting requirements;
• Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance; • An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and • Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.

The City implements a Sewer Pipe Blockage Control Program, which aims to prevent the discharge of fats, oils, grease, rags, and debris into the sanitary sewer and storm drain systems. The program also aims to prevent spills and illegal discharge into the storm drain, subsequently improving public health and safety and reducing sewer maintenance costs.

Over the last 10 years (2015-2024), there have been zero (0) spills total, and therefore zero (0) spills have been attributed to fats, oils, grease, rags, and debris. The City uses CCTV inspection to identify and monitor preventative maintenance areas that are likely sources of FOG into the sewer system. These areas are cleaned at least every 6 months.

PAGE 412 of 623
Element 7: Sewer Pipe Blockage Control Program
City of San Marino Sewer System Management Plan Page 38 Chapter 14, Article 15 (Fats, Oils, and Greases) of the City Municipal Code provides the legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages. This ordinance also provides guidance on installation and enforcement of grease interceptors.

All new restaurants are required to install a grease interceptor and must receive approval of the design of the grease interceptor by the Engineering Department and/or the San Marino Planning & Building Department through a plan checking procedure. In efforts to standardize the installation of FOG removal devices, the City has created materials on best management practices (BMPs), maintenance requirements, and design standards for the installation of grease removal devices (interceptors/traps) for FOG-producing facilities, all based on the California Plumbing Code.

Additionally, the City requires food service establishments (FSEs) to maintain a grease trap or interceptor cleaning log as part of its permitting program. The City does not provide a list of grease haulers to private businesses or private owners; it is the responsibility of these parties to hire a licensed grease hauler as needed.

LA County Public Health is responsible for performing FSE inspections. These inspections are done one to two times per year, depending on the capacity of the restaurant.

The City recently added educational materials on proper FOG disposal to the Streets, Sidewalks, & Sewer Maintenance section of its website.

PAGE 413 of 623
City of San Marino Sewer System Management Plan Page 39 8 System Evaluation, Capacity
Assurance, and Capital Improvements
This chapter discusses the City’s capacity management measures, including the most recent Master Plan and recommended capacity improvement projects.

Requirements:

D.8. SYSTEM EVALUATION, CAPACITY ASSURANCE AND CAPITAL IMPROVEMENTS: The Plan must include procedures and activities for:
• Routine evaluation and assessment of system conditions; • Capacity assessment and design criteria;
• Prioritization of corrective actions; and
• A capital improvement plan.

8.1 System Evaluation and Condition Assessment: The Plan must include procedures to:
• Evaluate the sanitary sewer system assets utilizing the best practices and technologies available; • Identify and justify the amount (percentage) of its system for its condition to be assessed each year; • Prioritize the condition assessment of system areas that:
a. Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;
b. Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas;
c. Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act section 303(d) List;
• Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods;
• Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State; • Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and
• Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions.

8.2. Capacity Assessment and Design Criteria: The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events; PAGE 414 of 623
Element 8: System Evaluation, Capacity Assurance, and Capital Improvements City of San Marino Sewer System Management Plan Page 40 • The appropriate design storm(s) or wet weather events that causes or contributes to spill events; • The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.

The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change;
• Increases of erosive forces in canyons and streams near underground and aboveground system components due to larger and/or higher-intensity storm events; • Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities.

8.3. Prioritization of Corrective Action: The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills.

8.4. Capital Improvement Plan: The capital improvement plan must include the following items:
• Project schedules including completion dates for all portions of the capital improvement program; • Internal and external project funding sources for each project; and • Joint coordination between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects; and Interagency coordination with other impacted utility agencies.

8.1 System Evaluation and Condition Assessment
The City conducted its most recent wastewater system condition assessment in 2018-2019, covering 20 miles of its 50-mile system. The report included a review of CCTV inspection footage and observations at pump stations to evaluate the system’s condition and identify necessary improvements. A list of Capital Improvement Program (CIP) projects was developed, along with associated costs. This assessment recommended that the City evaluate the remaining 30 miles to complete a full system review. The City plans on schedule and budget for this in the future.

Currently, the City’s contractor performs scheduled CCTV inspections to meet their schedule of CCTV inspecting the entire system every 2 years. If a non-urgent problem is identified in the CCTV inspection by the contractor, this is sent to the Engineering Department so it can be added to a list of flagged pipe segments and efforts are made to schedule their repair over time. If the repairs are not done before the next wastewater condition assessment report, they are then added to the new CIP list, including Grade 5 pipelines.

The City has not yet allocated funding or formally scheduled its next wastewater system condition assessment but plans to initiate the assessment in Fiscal Year 2026-27.

PAGE 415 of 623
Element 8: System Evaluation, Capacity Assurance, and Capital Improvements City of San Marino Sewer System Management Plan Page 41 With the anticipated sewer fund starting in FY26 as proposed by the 2024 Sewer Rate Study, the City will be able to address known issues such as structural damage, corrosion, root intrusion, and manhole degradation.

8.2 Capacity Assessment and Design Criteria
In the 2019 Sewer Condition Assessment Report, it was determined that a hydraulic model was not necessary for capacity assessment, as the City’s system is already fully built-out. However, it was recommended that the City perform flow monitoring in order to reduce I&I issues and to assess capacity. The City plans to schedule and budget this in the future.

The City has not experienced any sanitary sewer spills due to hydraulic deficiencies and/or limited capacity in the sewer system in the past ten years. Should capacity-related spills begin to occur, the City will reevaluate the need for a formal capacity evaluation and hydraulic model development.

8.3 Prioritization of Corrective Action
Previously, the City identified recurring issues identified during CCTV inspections but lacked a formal process for scheduling and tracking future repairs. The City now plans to implement a more consistent and formalized process.

8.4 Capital Improvement Plan
The 2018-2019 wastewater condition assessment found that 13 of the 20 miles evaluated required lining. It is anticipated that additional lining needs will be identified once the remaining 30 miles of the system area is assessed. Although the recommended Capital Improvement Plan (CIP) lining projects have not yet been implemented, the City plans to schedule and budget for them in the future.

The 2018-2019 wastewater condition assessment also recommended implementing a manhole inspection program, which the City began to implement in 2024. This task is now part of the scope of work for the City’s sewer maintenance contractor, Premier Pipe. As part of their routine cleaning and CCTV inspections, Premier Pipe inspects manholes and documents their findings. These reports include defect ratings and are provided to the City for review.

For capital improvements, the City has currently been performing rehabilitation and replacement projects as condition-related issues arise. Pipelines needing immediate attention would be scheduled for rehabilitation or replacement immediately by the City’s contractor. All other rehabilitation or replacements will be generated into a project after City’s review.

The City completed a handful of projects in the past few years including: Del Mar Ave Pipeline Repair project (2024), California Blvd & Allen Ave Sewer Rehab Project (2023), Lorain Rd Sewer Repair project (2023), Virginia Rd Sewer Rehab project (2022), along with 7 manhole rehabilitations (2023). Only two of these projects are part of the 2018- 2019 CIP list. The City plans on completing the rest of the CIP projects by 2035.

On January 10, 2024, the City awarded a contract to CWS Systems, Inc. for the rehabilitation and upgrade of all three lift stations. Due to long lead times for several components, construction is currently underway and is expected to be completed by February 4, 2026.

The City only uses the General Fund for sewer construction and maintenance, including CIP projects. In 2025, the City conducted a Sewer Rate Study to propose a new sewer facility charge to be used for sewer construction and maintenance. The newly implemented sewer unit charges are expected to generate revenue to fund sewer PAGE 416 of 623
Element 8: System Evaluation, Capacity Assurance, and Capital Improvements City of San Marino Sewer System Management Plan Page 42 operating expenses and cover approximately half (49%) of the Capital Improvement Program (CIP). The City is anticipating for this new fund to take effect in FY 25-26.

Once potential projects are identified in the next condition assessment report, which is anticipated for FY 26/27, the City intends to prioritize them based on the urgency of repair or replacement needs. In addition to this new list, any incomplete projects from the previous CIP list will also be incorporated into the new list and prioritized. This priority list will be utilized to determine a schedule for completing these projects. Funding sources will also be identified in the report.

City of San Marino Sewer System Management Plan Page 44 9 Monitoring, Measurement and
Program Modifications
This section of the SSMP discusses parameters the City tracks to monitor the success of the SSMP and how the City plans to keep the SSMP current.

Requirements:

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

In the past, the City did not have a formal process for tracking the success of SSMP elements. As issues arose and elements changed, the City tracked certain segments of each element of the SSMP such as organizational changes and system maintenance. Currently, the City is motivated to be proactive properly maintaining the sewer system and understand how tracking their SSMP elements will improve efficacy of this goal.

The City will perform regular tracking of the SSMP elements and their effectiveness. The City will develop a database, or similar tool, to maintain specific information related to the SSMP, as a central repository for changes to the SSMP and regularly track the success of SSMP elements. As for preventative maintenance activities (shown in Table 9-3, these are to be tracked and provided by the City’s contractor, Premier Pipe, Inc. The City will evaluate whether SSMP elements have changed so that changes can be documented in a Change Log to include the specific change, the date of the change and the name of the person making the change. The Change Log is included in Appendix I. Procedures and activities will be updated based on the tracking and assessment methods described therein. Table 9-1 details a schedule for evaluating the Monitoring, Measurement, and Program Modifications.

The City will use the specific monitoring parameters listed in Table 9-2 and documented on the tracking sheet included in Appendix J to assist in completion of the annual SSMP Audit described in Plan Element 10, Internal Audits. The City will also continue to collect data for all performance measures currently tracked. This additional information that the City collects, such as customer complaints and length of pipe cleaned, will be used to support or further evaluate the success and limitations of the SSMP as needed.

The City’s contractor tracked scheduled preventative maintenance, repairs, and cleaning activities and is committed to improve on the consistency of this tracking, including beginning to track system deficiencies with recurrent issues to further support the success of the SSMP. The City’s contractor has consistently tracked the components listed in Table 9-3 to quantitatively determine the effectiveness of preventive operation and maintenance activities. Using this data and comparing it to spill data shown in Table 9-4, the current preventative operation and maintenance activities appear to be successful in reducing spills.

This chapter discusses the City’s SSMP auditing program.

Requirements:

D.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.

The reissued State Water Resources Control Board’s Order Number WQ 2022-0103-DWQ requires that an agency conduct an internal audit of its SSMP at least once every three (3) years. The audit is to evaluate how the City has developed and implemented each of the eleven elements of the SSMP and how each element is functioning to assist in the prevention of sanitary sewer spills. The audit report shall be kept on file at the City offices and uploaded to the online California Integrated Water Quality System (CIWQS) database within 6 months after the end of the 3- year audit period. Any deficiencies found during the audit are addressed and corrected.

The due dates for the City’s SSMP and SSMP audits can be found here using the City’s WDID (4SSO10428):
https://www.waterboards.ca.gov/water_issues/programs/sso/lookup/ In 2025, the City contracted with Dudek to complete its audit and work closely with the City’s staff to review the SSMP, its implementation, and the effectiveness of the City’s efforts in reducing spills.

The City plans to complete audit requirements and due dates corresponding to the original audit cycle deadlines.

The City’s next SSMP audit is to be completed and uploaded to CIWQS by February 2, 2028. During this next audit, the City will:
• Evaluate the effectiveness of each SSMP element and identify areas of improvement. • Assess progress in implementing the SSMP and preventing sanitary sewer spills. • Review monitoring, measurement, and program modifications under Element 9. • Summarize system improvements completed in the previous year. • Outline planned system improvements for the upcoming year, including a proposed schedule.

Audit findings and recommendations will be incorporated into future SSMP Updates to ensure continuous improvement and regulatory compliance.

11 Communication Program
This section of the SSMP discusses the City’s communications with the public.

Requirements:

D.11. COMMUNICATION PROGRAM: The Plan must include the following items as appropriate and applicable to the Enrollee’s system:

The Plan must include procedures for the Enrollee to communicate with:
• The public for:
d. Spills and discharges resulting in closures of public areas, or that enter a source of drinking water, and e. 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:
f. System operation, maintenance, and capital improvement-related activities.

The City maintains a public website (https://www.cityofSan Marino.net) to share updates, alerts, and news with residents. The homepage provides important announcements, City Council meeting agendas and minutes, and other key information for City residents.

Once approved, the City’s SSMP will be available on the City’s Streets, Sidewalks, & Sewer Maintenance section of the website
(https://www.sanmarinoca.gov/government/departments/parks___public_works_/streets,_sidewalks___sewer_maint enance.php). The SSMP link will include contact information for the Parks & Public Works Department to provide opportunities for public input on plan implementation and future updates. Hard copies of the SSMP are also available at the City office.

The San Marino City Council incorporates opportunities for public input regarding any sewer system concerns at its Board meetings. The Sewer Rate Study has been presented in public meetings, with opportunities for community feedback on its findings and financial implications related to sewer use fees.

The City has not experienced any sewer spills in the past ten years and, therefore, has not needed to notify the public about any incidents. In the event of a spill or discharge, the City will provide timely public notifications based on the location and severity of the incident. Communication methods may include website updates, social media posts, and notices posted in the vicinity of the discharge.

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.

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)).

2.2. Requirements for New Regulatory Coverage
No later than 60 days prior to commencing and/or assuming operation and maintenance responsibilities of a sanitary sewer system, a duly authorized representative that PAGE 435 of 623

2.3. Regulatory Coverage Transfer
Regulatory coverage under this General Order is not transferable to any person or party except after an existing Enrollee submits a written request for a regulatory coverage transfer to the Deputy Director, at least 60 days in advance of any proposed system ownership transfer. The written request must include a written agreement between the existing Enrollee and the new Enrollee containing:
• Acknowledgement that the transfer of ownership is solely of an existing system with an existing waste discharge identification (WDID) number; • The specific ownership transfer date in which the responsibility and regulatory coverage transfer between the existing Enrollee and the new Enrollee becomes effective; and
• 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)).

PAGE 437 of 623

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 PAGE 438 of 623

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

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

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

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

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

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.

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)
PAGE 441 of 623

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
12 • Commercial and Sport Fishing (COMM)
• Subsistence Fishing (SUB)
• Tribal Tradition and Culture (CUL)
• Tribal Subsistence Fishing (T-SUB)
• Aquaculture (AQUA)
• Marine Habitat (MAR)
• Preservation of Biological Habitats of Special Significance (BIOL) • Migration of Aquatic Organisms (MIGR)
• Shellfish Harvesting (SHELL)
• Industrial Process Supply (PROC)
• Industrial Service Supply (IND)
• Hydropower Generation (POW)
• Navigation (NAV)
• Flood Peak Attenuation/Flood Water Storage (FLD)
• Water Quality Enhancement (WQE)
• Fresh Water Replenishment (FRSH)
• Groundwater Recharge (GWR)
• Inland Saline Water Habitat (SAL)

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

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:

PAGE 442 of 623

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 PAGE 444 of 623

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
15 Compliance While Maintaining Water Quality Protection.

SANITARY SEWER SPILL MONITORING PLAN
1 DECEMBER 2024
1 Introduction
The Sanitary Sewer System Spill Water Quality Monitoring Plan (Monitoring Plan) provides technical information for water quality monitoring locations and techniques that may be used to characterize the relative impacts to the receiving water quality in the event of a sanitary sewer spill (spill) within the City of San Marino (City) service area.

In the event of a spill, it is assumed response actions identified in the City’s Spill Emergency Response Plan and Sewer System Management Plan (SSMP) will be implemented to protect public health and the environment. This plan covers details on monitoring receiving water quality separate from the emergency response and cleanup efforts.

Recent updates to the waste discharge requirements general order for sanitary sewer systems1 (WDR) require timely implementation of spill-specific notification, monitoring, and reporting tasks for spill events that exceed certain volume thresholds. In the event of a spill >50,000 gallons, the WDR outlines monitoring requirements generally aligned to estimate spill location and spread as well as receiving water conditions to support impact analysis documented in a spill report. This Monitoring Plan provides technical and procedural details to allow for rapid implementation of water quality monitoring activities that may be used to characterize the extent and magnitude of potential impacts related to a spill. These water quality activities are based on standard procedures implemented as part of municipal and industrial water quality monitoring programs.

Surface runoff in the geographical area served by City flows into both City of San Marino storm drains and Los Angeles County Flood Control District (LACFCD) storm drains. Receiving water quality monitoring has been conducted in these drains as part of various compliance, special study, and third-party efforts over the past two decades.

The City owns and operates the sanitary sewer collection system within its service area. The system is designed to transport sanitary sewage to trunk sewers operated by the Sanitary Districts of Los Angeles County for further transportation, treatment, and eventual discharge. The location of major collection system assets and components, watershed configuration, drainage characteristics, safety, and accessibility shall be used to select a distributed array of water quality monitoring locations that may be used during a spill response event. In the event of a spill, it is recommended that City staff evaluate the spill size, location, duration, volume, and ambient weather conditions to develop a focused water quality monitoring strategy and monitoring plan.

The overall purpose of this document is to provide the following information:
• A geographic overview of City assets
• Guidance on identifying representative water quality monitoring locations for spill response • A summary of water quality monitoring methods and protocols The following sections provide background information and sample collection methodology for identifying monitoring locations.

SANITARY SEWER SPILL MONITORING PLAN
2 DECEMBER 2024
2 Background
Wastewater and stormwater2 discharges from the City are regulated through state issued permits that define management, monitoring, and reporting requirements. These WDRs are created based on evaluation of the City’s threat to water quality and quality of the receiving waters.

The City operates under the Coastal Watersheds of Los Angeles County Phase I municipal separate storm sewer system (MS4) permit (MS4 Permit) and is part of the Upper Los Angeles River Watershed Management Area Group.

Under the MS4 Permit, the City monitors storm drain outfalls during wet- and dry-weather to detect non-storm water discharges to its MS4 and monitoring water quality during storm events as part of the Coordinated Integrated Monitoring Program (CIMP). Non-stormwater discharges may come from many sources including, but not limited to, illicit connections, illicit discharges, and sewage spills. This document pertains to water quality as a result of a sewage spill, however, monitoring results from the regional CIMP are useful for comparison with spill event samples.

2.1 Spill Monitoring Plan Framework
The WDR Attachment E1 (Appendix A) includes spill notification, spill location and spread observations, monitoring, and reporting requirements. Implementation requirements for these elements are summarized below.

Notification
For any spill that discharges in or on any waters of the State, the discharger is to notify the California Office of Emergency Services as soon as possible but no later than two (2) hours after: a) knowledge of the spill; and b) notification can be provided without interfering with cleanup/emergency measures.

Location and Spread Observations
In the event of a spill, the discharger is to visually assess the spill locations and extent using photography, global positioning system (GPS) and other tools. Key documentation:
• The system location where spill originated
o For multiple appearance points of a single spill event, the points closest to the spill origin. • Drainage conveyance system spill entry locations
• Locations where spill discharges to receiving waters
• Extent of spread and locations of cleanup
2 National Pollutant Discharge Elimination System (NPDES) Waste Discharge Requirements (WDRs) for Municipal Separate Storm Sewer System (MS4) Discharges within the Coastal Watersheds of Los Angeles County, Except those Discharges originating from the City of Long Beach MS4 Order R4-2012-0175-A01 NPDES NO. CAS004001 PAGE 546 of 623

SANITARY SEWER SPILL MONITORING PLAN
3 DECEMBER 2024
Additionally, the discharger needs to estimate the spill volume using appropriate techniques, calculations, and documentation for electronic reporting.

Following spill volume estimation, the discharger is required to perform visual observations for spills that discharge to receiving waters. Key documentation includes:
• Estimated spill travel time to receiving water
o For spills entering a drainage conveyance system, this includes travel time from entry into the drainage conveyance system to receiving water discharge • Spill volume entering receiving water
• Photography:
o Waterbody bank erosion (if applicable)
o Floating matter
o Surface sheen (oil and grease)
o Discoloration of receiving waters
Monitoring
A spill estimated at 50,000 gallons or greater discharged to a receiving water requires the discharger to perform water quality monitoring. Monitoring must be conducted no later than 18-hours after the discharger’s knowledge of a potential discharge to a surface water.

Daily samples must be collected at the discharge point to the receiving water and at locations upstream and downstream of the discharge point. If the spill entered the receiving water from a drainage conveyance, a sample must be taken from within the conveyance as well, given spill material is still present. Upstream samples should be taken at a sufficient distance from the discharge point to capture ambient conditions absent of spill material.

Downstream sample point must be taken far enough from the discharge point where the spill material is fully mixed with the receiving water.

Once collected, the samples must be submitted to a certified laboratory in a timely manner for analysis of ammonia and fecal indicator bacteria.

Reporting
Electronic reporting to the California Integrated Water Quality System (CIWQS)3 is required for all spills. For spills greater than 50,000 gallons and discharged to receiving waters, a Spill Technical Report is required within 45 days of the spill end date. The Spill Technical Report must contain the following:
• Spill causes and circumstances
• Discharger’s response to spill
• Water quality monitoring information
• Evaluation of spill impacts, including short- and long-term impact(s) to beneficial uses of surface waters Spill report information is then used by Regional Water Quality Control Board staff to evaluate the relative impact to the environment and to form the basis of potential spill-specific enforcement actions.

2.2 Geographic Setting
The City drains to the south, with elevations ranging from approximately 558 feet above sea level at City Hall, increasing to the north toward the San Gabriel Mountains4. The major drainage areas within the City include Arroyo Seco, Rubio Wash, and Eaton Wash. Generally, these drainage areas flow north to south.

2.3 San Marino Assets
The City operates and maintains a sanitary collection system that provides service to approximately 12,000 residents5. The City operates and maintains approximately 50 miles of gravity pipelines and three (3) pump stations, which serves the majority of the City’s 3.8 square mile City limits, as shown in Figure 1. The City’s sanitary collection system conveys these untreated flows to the Los Angeles County Sanitation District’s (LACSD) trunk sewer system.

There are five (5) LACSD trunk sewers running through the City of San Marino. In general, these assets constitute infrastructure that have potential to contribute to spills that may require a monitoring program and shall be used in the sample location assessment outlined in Section 3.

2.4 Potential Monitoring Locations
Within the context of the City’s geography and sewer system assets, the City shall identify potential spill monitoring locations. The monitoring locations shall be selected to provide core representation of locations where critical sewer infrastructure has potential for a large spill event, adjacent stormwater conveyance and other infrastructure has potential to be impacted by a large spill event, and during/post-event monitoring at the selected locations may provide reasonable capacity to characterize impacts to water quality from a spill. A spill that impacts water quality is likely to be conveyed through the MS4 before reaching the receiving water, however, in limited situations a spill immediately adjacent to a receiving water may discharge directly to the water body. The WDR defines four distinct monitoring location types (Figure 2):
• Flow in MS4 or non-sewer infrastructure conveyance(s) prior to the discharge point • Receiving Surface Water (RSW) discharge point
• RSW upstream of the discharge point
• RSW downstream of the discharge point
A spill event will determine the exact monitoring location(s) needed to be sampled based on discharge point to the receiving water. However, the guidelines for identifying core monitoring locations and methods documented in this Monitoring Plan allow for rapid implementation of a monitoring program that will both meet the requirements of the WDR and provide critical information that may be used to inform the required Spill Technical Report impact analysis.

Accordingly, this Monitoring Plan only provides guidance on identifying potential upstream and downstream monitoring locations. Monitoring in the MS4 or non-sewer infrastructure conveyance(s) as well as RSW discharge point monitoring will require the City to evaluate on a spill-by-spill basis where to setup these locations.

Additional information detailing how to identify upstream and downstream monitoring locations for this Monitoring Plan is presented in Section 3.

2.5 Water Quality Sample Constituents
Attachment E of the WDR lists two required constituents to monitor in surface water impacted by a sewer spill. All water quality samples are required to measure the concentration of ammonia and the concentration of the appropriate bacterial indicator(s) per the applicable Basin Plan water quality objectives. For San Marino, the Los Angeles Regional Board's Basin Plan6 identifies E-coli and Enterococcus as the fecal indicator bacteria for the region. Table 1 identifies the required constituents to sample for and information on the specific requirements for each sample method.

3 Monitoring Site Selection
The City shall conduct an analysis using the location of known City assets, watershed boundaries, and the City boundary. The analysis will result in a suite of potential monitoring locations that are prioritized based on the following characteristics:
• Proximity to City sewer assets
• Ability for a spill to flow to a receiving water
• Potential for monitoring site to serve as a reference point for the City As previously mentioned, the monitoring sites shall be chosen for their ability to characterize water quality conditions before and after being influenced by the City. Due to the transient nature of a spill, the drainage conveyance system and discharge point monitoring locations are spill specific and cannot be identified in preplanning.

Downstream monitoring locations are defined in the WDR as being “a point in the receiving water, downstream of the point of sewage discharge, where the spill is fully mixed with the receiving water.” Receiving waters in the City are defined by three separate watersheds: Arroyo Seco, Rubio Wash, & Eaton Wash. For each channel, the City shall identify all downstream points at the City boundary to use as monitoring locations for sample collection. These points represent where a spill that discharged into the channel upstream either from a storm drain outfall or surface runoff is fully mixed with the receiving water.

The WDR defines an upstream monitoring site as being “a point in the receiving water, upstream of the point of sewer discharge, to capture ambient conditions absent of sewage discharge impacts.” For the Monitoring Plan, upstream monitoring locations shall be selected for each of the major drainage areas upstream of City sewer assets and storm drain outfalls. Upstream monitoring locations shall also be selected based on proximity to major roads and ease of access to the receiving water.

In the event of a spill, it is recommended that City staff evaluate the spill location with respect to these guidelines and determine an appropriate upstream and downstream monitoring location. The drainage conveyance and discharge point monitoring location should be identified by visually inspecting the spill pattern on the ground surface and identifying if any material has flowed into the MS4 and/or directly discharged into a surface water.

4 Monitoring Procedures Overview
In general, monitoring locations shall be located in open stormwater channels and methodology derived from industry standard water quality sample collection procedures shall be used. Standard methods include documenting site conditions and sample characteristics (color, odor, turbidity, etc.), flow estimations, and other observations and activities that may be used to evaluate water quality or sample collection specifics.

Water quality monitoring requires the coordination of both field personnel and the selected analytical laboratory during monitoring events, as well as proper management of field and laboratory data. Monitoring event preparation includes allocating sample collection equipment, bottles, labels, and chain of custodies (CoCs). Activities to be performed during a monitoring event include the proper collection and handling of water samples and the submission of samples within laboratory holding times. In addition to the field effort involved with monitoring, such as travel, parking, sample collection and handling, additional effort is required after a monitoring event to ensure the proper management of field and analytical data.

Monitoring locations should be assessed for representative conditions prior to collecting a water sample. For example, collection of a sample should target flowing water in riverine locations and avoid stagnant pools. If a monitoring location does not offer such conditions, a sample may still be collected, but field notes shall include observations such as pooled water, presence of algae (and volume estimates), and other biological conditions. It is recommended that City staff review available sample collection and handling resources [e.g., Caltrans Monitoring Guidance Manual7 (Caltrans 2020), NPDES Stormwater Sampling Guidance Document8 (EPA 1992)] prior to a monitoring event, and/or consult a water quality professional, as necessary. A brief synopsis of the key monitoring and flow measurement protocol are provided below in Section 4.1 and 4.2.

4.1 Manual Sample Collection
Manual sample collection involves filling a container from a runoff stream or receiving waterbody. This can be done either by collecting the sample directly into laboratory-supplied bottles or by using an intermediate container to pour the sample into the lab bottles. Note that samples for certain constituents, including oil and grease, bacteria, and low-level mercury, are best if collected directly into the appropriate sample bottle without use of an intermediate container, however, in certain situations that might not be feasible and intermediate container is necessary.

An intermediate sample container can be an unused laboratory bottle, and sample collection can be assisted by a device that is extended to dip, lower, or reach the sample container into the waterbody. This method is ordinarily used when the waterbody is difficult to access, and an intermediate container must be lowered into the water or reached 7 https://dot.ca.gov/-/media/dot-media/programs/environmental-analysis/documents/env/ctws-ot-20-350-04-01-monitoringguidance-manual-a11y.pdf 8 https://www3.epa.gov/npdes/pubs/owm0093.pdf

across some distance to collect a sample. Additionally, the use of an intermediate container when filling prepreserved laboratory bottles can be beneficial because it eliminates the risk of accidentally rinsing out the preservative while filling the bottles.

4.2 Flow Rate Estimation via Float Velocity Method
To use this method, first it is necessary to determine the cross-sectional area of the flow at a specific location. This requires estimation of flow depth and width, as well as a general assessment of the bottom channel shape such as rectangular or trapezoidal. Then field technicians mark two places on the bank of the channel at least five feet apart (using a longer distance between the two points will result in a more accurate flow measurement).

When this setup is complete, the flow can be measured by releasing a buoyant object into the channel upstream of the two marked points on the bank and measuring the time it takes to flow between them. The rate of flow can be calculated by the following formula:

Equation 1:

𝐹𝑙𝑜𝑤 𝑅𝑎𝑡𝑒 (
𝑓𝑡3
𝑠𝑒𝑐 ⁄ ) =
𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝐵𝑒𝑡𝑤𝑒𝑒𝑛 𝑃𝑜𝑖𝑛𝑡𝑠 (𝑓𝑡)
𝑇𝑟𝑎𝑣𝑒𝑟𝑠𝑒 𝑇𝑖𝑚𝑒 (𝑠𝑒𝑐)
× 𝐶𝑟𝑜𝑠𝑠 𝑆𝑒𝑐𝑡𝑖𝑜𝑛𝑎𝑙 𝐴𝑟𝑒𝑎 (𝑓𝑡2)
There are some disadvantages to the float method: (1) measuring the cross-sectional area of a large water body can be difficult, and inaccuracies in this value will affect the accuracy of the flow measurement, and (2) the method measures velocity of flow only at the surface of a channel, which may not be representative of the velocity throughout the entire cross section of flow. Therefore, when using this method, multiple measurements should be taken at different points across the channel and the results averaged.

The accuracy of the float method is improved by using an object that has a density similar to water and that tends to float totally submerged. For example, oranges are good floating objects for this method because they are easy to see, remain buoyant, and are environmentally safe.

The float method should only be used if a mechanical flow meter is not available. Mechanical flow meters, such as a turbine flow meter or ultrasonic flow meter, will provide more accurate flow velocity at a given point. The crosssectional area will still need to be estimated to calculate a flow rate, however, flow meters help reduce the time, effort, and potential inaccuracy introduced by the manual float method.

4.3 Monitoring Equipment
The use of proper monitoring equipment is necessary to ensure the safety of personnel collecting the samples and integrity of the samples themselves. Contact with raw sewage can have acute and long-term impacts to human health that can be avoided using the proper personal protective equipment (PPE). Additionally, contamination of the sample may occur if inappropriate equipment or handling methods are used.

Recommended PPE for receiving water monitoring includes:
• Disposable latex gloves
PAGE 555 of 623

SANITARY SEWER SPILL MONITORING PLAN
12 DECEMBER 2024
• Close-toed shoes, long pants, and long sleeve shirt
• Optional Tyvek suit or similar if contact with the spill material is likely • Eye protection (glasses or goggles) and/or face shield • Disinfecting wipes and hand sanitizer
To be ready for a spill, it is recommended the following list of equipment is procured and stored in a centralized location. Store enough sampling bottles to be able to collect up to four days of samples at each of the four monitoring location types described in Section 2.4. In the event that any of the bottles are lost or compromised, it is recommended to also have a full set of backup bottles. • Four days’ worth of sample bottles plus one days’ worth of back-up includes:
o 40 x 100 mL plastic bottles with Sodium thiosulfate preservative o 20 x 250 mL plastic bottles with Sulfuric acid preservative • Sample bottle labels and water-resistant marker
• CoC sheets (Appendix B)
• Visual observation log (Appendix C)
• Cooler for ice to keep samples at or below 4°C
• Grab pole to safely reach into drains as needed
For additional resources, the Caltrans and/or EPA guidance documents referenced at the beginning of this section can serve as a general guide for collecting water quality samples. While these documents focus on stormwater sampling, the safety protocols and handling methods apply to the receiving water monitoring discussed in this plan.

4.4 Water Quality Laboratory
Monitoring samples must be taken to an Environmental Laboratory Accreditation Program (ELAP) certified laboratory for analysis. The closest public ELAP certified laboratory is in Pasadena:
• City of Los Angeles Dept. of Water & Power, Water Quality Laboratory. Located at 555 East Walnut Street, Pasadena.

In the event that the local laboratories are unavailable during a spill event, consult the State Water Resources Control Board ELAP webpage9 for a mapping tool that shows the closest laboratories and their contact information. 9 https://www.waterboards.ca.gov/drinking_water/certlic/labs/ PAGE 556 of 623

SANITARY SEWER SPILL MONITORING PLAN
13 DECEMBER 2024
5 Site Access and Safety Considerations
Access to monitoring locations must be assessed for safety considerations during each visit. Field staff should use caution at all times in evaluating roadway safety and right of way conditions. Specific safety concerns relating to surface water sampling includes potential slip, trip, and fall hazards, biological hazards, and swift water. To reduce safety risks, grab poles should be considered for sample collection at difficult to reach monitoring locations.

Unlike receiving water monitoring locations, drainage conveyance monitoring locations are often located in the street and require some level of traffic control based on the type of road and time of day. Compounding this issue is that spills frequently occur during rain events which make for even more dangerous road conditions. Monitoring locations presented in this plan are intended to represent the most optimal location from a data standpoint, but not necessarily from a personnel safety standpoint. At all times, personnel safety should be the top priority, and monitoring should be delayed or relocated if safety is potentially compromised.

Site-specific access and safety considerations are presented in the following section. 6 Summary
This Monitoring Plan provides the City with technical guidance for monitoring receiving water quality in the event of a sewer spill. Water quality monitoring can help the City determine the relative impact of a spill and help guide management decisions relating to remediation and spill response. These monitoring protocols and site-specific descriptions provide City staff with a detailed guidance document for performing water quality monitoring and assessing impact to waterbodies following a sewer spill.

Guidance on selecting monitoring locations for this Monitoring Plan was provided, focusing on identifying sites based on their proximity to City assets, drainage characteristics, safety, accessibility, and the ability to isolate runoff from a spill that is only influenced by the City. Drainage conveyance and point of discharge monitoring locations will be determined in real time if a spill reaches the receiving water. All monitoring sites chosen by the City are subject to change should a different site be identified as preferable for properly characterizing impacts to water quality from a spill event. It is recommended that the City periodically visit their selected monitoring locations to ensure they remain accessible and safe.
