STAFF REPORT
RE: Resolution of the Board of Directors of the City of Lakeport Municipal Sewer District (CLMSD) adopting the Sewer System Management Plan (SSMP) update, and authorizing CIWQS certification MEETING DATE: 04/21/2026
SUBMITTED BY: Jen Baker, Compliance Officer on behalf of Paul Harris, Utilities Director PURPOSE OF REPORT: Information only Discussion Action Item WHAT IS BEING ASKED OF THE CITY COUNCIL/BOARD:

Adopt a resolution approving the City of Lakeport Municipal Sewer District (CLMSD) Sewer System Management Plan (SSMP) update, and authorize the Compliance Officer to certify the document in the California Integrated Water Quality System (CIWQS) on behalf of the CLMSD Director.

BACKGROUND/DISCUSSION:

The State Water Resources Control Board requires all California public agencies operating sanitary sewer systems to prepare and maintain a Sewer System Management Plan, a program document describing how the agency manages, operates, and maintains its wastewater collection system to protect public health, prevent sewer overflows, and ensure long-term system reliability. CLMSD has maintained an SSMP since 2010. Under the current governing order (Order WQ 2022-0103-DWQ), CLMSD is required to certify an updated SSMP in CIWQS by May 2, 2026.

Staff used this required update cycle as an opportunity to comprehensively review and strengthen each program area, formalize existing practices, establish clear performance frameworks, and align the document with the current governing order and the District's adopted 2025 Sewer Master Plan Update. This SSMP update reflects a more mature and complete picture of how the District operates and provides a stronger foundation for ongoing compliance, system management, and regulatory reporting.

The updated SSMP establishes a formal performance monitoring program with measurable targets and a regular review cadence; modernizes the District's Fats, Oils, and Grease control program with updated inspection authority and outreach materials; strengthens overflow emergency response documentation; and fully integrates the adopted 2025 Sewer Master Plan Update as the District's current capacity and capital improvement planning foundation. The SSMP is structured as a living document with built-in tracking and change management processes to carry the program forward.

Board adoption of the resolution presented with this report is the final step required prior to CIWQS certification of the updated plan by the May 2, 2026, deadline.

Meeting Date: 04/21/2026 Page 2 Agenda Item # IV.F.

List of Key Terms and Definitions
The following terms are used throughout this Sewer System Management Plan. Definitions reflect the requirements and terminology of State Water Resources Control Board Order WQ 2022-0103-DWQ unless otherwise noted.

Term Definition
Authorized
Representative
The person designated by a public agency as either a principal executive officer or duly authorized representative. For CLMSD, this is the CLMSD Director or the Compliance Officer, as designated.

Average Dry Weather
Flow (ADWF)
The average daily flow of wastewater to the treatment plant during dry weather conditions, excluding significant rainfall-driven inflow and infiltration. Used as a baseline capacity metric. This is determined by the total flow for the months of August through October, inclusive, divided by 92 days.

Blockage A partial or full obstruction of wastewater flow through a sewer pipeline.

Causes include debris, grease buildup, root intrusion, or structural collapse.

Also called a stoppage. If not addressed in time, a blockage can result in an overflow.

Capital Improvement Plan
(CIP)
A prioritized, scheduled, and funded program identifying infrastructure projects needed to maintain system capacity, reliability, and compliance. For CLMSD, the current CIP is established in the 2025 Sewer Master Plan Update.

Category 1 SSO A sanitary sewer overflow of any volume that reaches a surface water body or drainage channel leading to surface water, or that is not fully recovered.

Requires immediate notification to regulatory agencies.

Category 2 SSO A sanitary sewer overflow of 1,000 gallons or greater that does not reach surface water. Requires regulatory reporting through CIWQS.

Category 3 SSO A sanitary sewer overflow of 50 to 999 gallons that does not reach surface water. Requires regulatory reporting through CIWQS.

Category 4 SSO A sanitary sewer overflow of less than 50 gallons that does not reach surface water. Requires documentation but not external regulatory reporting.

Corrective Maintenance Unplanned maintenance performed in response to a failure, blockage, or system malfunction. Distinguished from preventive maintenance, which is scheduled and proactive.

Enrollee A public agency enrolled under State Water Resources Control Board Order WQ 2022-0103-DWQ that owns or operates a sanitary sewer collection system greater than one mile in length.

Exfiltration The underground exiting of sewage from a sanitary sewer system through cracks, offset or separated joints, or failed infrastructure. Exfiltration that remains in the subsurface and does not reach surface water is not classified as an SSO under the General Order.
5 / 352
Food Service
Establishment (FSE)
Any commercial establishment that prepares, serves, or otherwise handles food and discharges wastewater containing fats, oils, or grease to the municipal sanitary sewer system.

Grease Interceptor A plumbing device installed underground outside a food service establishment that uses gravity to separate and retain fats, oils, and grease from wastewater before it enters the sanitary sewer system.

Grease Trap A small, indoor plumbing device installed at an individual fixture that captures fats, oils, and grease before they enter the drain system. Typically used where a full grease interceptor is not required.

Inflow and Infiltration (I&I) Inflow refers to stormwater or surface water that enters the sanitary sewer system through direct connections such as roof drains or catch basins.

Infiltration refers to groundwater that enters through cracks, joints, or defects in pipes and manholes. Both increase system flows during wet weather and are a primary driver of peak wet weather flow at CLMSD.

Key Performance
Indicator (KPI)
A measurable target used to evaluate how well a program or process is achieving its intended outcomes. KPIs provide a basis for data-driven decisionmaking and continuous improvement.

Peak Wet Weather Flow
(PWWF)
The maximum rate of flow observed at the wastewater treatment plant during significant rainfall events, reflecting the combined effect of wastewater generation and I&I entering the collection system.

Preventive Maintenance
(PM)
Scheduled, proactive maintenance activities performed to reduce the likelihood of failure, blockage, or SSO. Includes gravity main cleaning, lift station inspections, and equipment servicing.

Private Lateral Sewage
Discharge (PLSD)
A sewage spill that originates from a blockage or failure within a privately owned sewer lateral, not the public collection system. PLSDs are reported separately from SSOs in CIWQS.

Receiving Water A water of the State that receives a discharge of waste. For CLMSD, the primary receiving water of concern is Clear Lake.

Resilience The ability of a sewer system and its operating agency to recover from or adjust to adversity or change, including infrastructure failures, extreme weather events, and regulatory changes.

Residential Unit
Equivalent (RUE)
A unit of measure representing the average wastewater flow generated by a single-family residential dwelling. Used to standardize capacity calculations across different land use types.

Sanitary Sewer Overflow
(SSO)
Any overflow, spill, release, discharge, or diversion of untreated or partially treated wastewater from a sanitary sewer system, including overflows that reach waters of the United States, overflows that do not reach such waters, and backups into buildings caused by conditions within the publicly owned portion of the sewer system.

Sanitary Sewer System A system of pipes, pump stations, sewer lines, or other conveyances upstream of a wastewater treatment plant headworks, used to collect and convey wastewater to a publicly owned treatment facility. Includes laterals owned and 6 / 352
operated by the Enrollee, satellite sewer systems, and temporary conveyance facilities.

Satellite Sewer System A portion of a sanitary sewer system owned or operated by a different entity than the owner of the downstream wastewater treatment facility. LACOSAN operates a satellite system that connects to CLMSD at the southern portion of the service area. These flows enter our collection system and conveyed to the WWTP for treatment.

Sewage 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.

Sewer System
Management Plan (SSMP)
A living document an Enrollee develops and implements to effectively manage its sanitary sewer system in accordance with Order WQ 2022-0103-DWQ.

Includes provisions for management, operation, and maintenance of the system, risk management, and a spill response plan.

System Evaluation and
Capacity Assurance Plan
A required SSMP element that evaluates hydraulic deficiencies in the collection system, establishes design criteria, and provides a prioritized Capital Improvement Plan to maintain hydraulic capacity for dry weather and wet weather flow conditions.

Wastewater Collection
System
See Sanitary Sewer System. Any system of pipes, pump stations, sewer lines, or other conveyances used to collect and convey wastewater to a publicly owned treatment facility.

This introductory section provides background on the regulatory basis for this Sewer System Management Plan (SSMP), describes the organization of the document, and provides an overview of the City of Lakeport Municipal Sewer District's service area and collection system.

Revision History
This document is Revision 5 of the City of Lakeport Municipal Sewer District (CLMSD) Sewer System Management Plan.

The table below summarizes the history of SSMP revisions.

Table 0.1 — SSMP Revision History
Revision Date Description
1 May 2010 Original SSMP adoption. Baseline document prepared by City of Lakeport Utilities Department.
2 March 2018 Updates include modifications to the district's SSO emergency response plan, monitoring and reporting program, and contact info updates 3 December 2022 Minor administrative update. Contact information and appendix materials revised.
4 May 2024 Administrative update. Contact list updated. No substantive program changes.
5 April 2026 Comprehensive update. Revised to comply with SWRCB Order WQ 2022- 0103-DWQ. Incorporates findings and corrective actions from the 2022– 2025 Triennial SSMP Audit. Integrates adopted 2025 Sewer Master Plan Update. New sections added for performance monitoring, FOG program modernization, post-incident review, and operator participation documentation.

Sewer System Management Plan Requirement Background
The State Water Resources Control Board (SWRCB) adopted Water Quality Order No. 2006-0003-DWQ on May 2, 2006, which first required all public agencies in California operating sanitary sewer systems greater than one mile in length to prepare and implement a Sewer System Management Plan and to report sanitary sewer overflows (SSOs) through the California Integrated Water Quality System (CIWQS).

In 2013, the SWRCB issued Order No. WQ 2013-0058-EXEC, amending the 2006 Order to establish a third SSO reporting category (Category 3 — spills fully contained within the collection system) and to clarify recordkeeping and reporting requirements for enrolled agencies.

In 2022, the SWRCB adopted Order WQ 2022-0103-DWQ, a comprehensive update to the Statewide General Waste Discharge Requirements that supersedes both the 2006 Order and the 2013 amendment. Order WQ 2022-0103-DWQ 8 / 352
governs all enrolled agencies, including CLMSD. This Revision 5 SSMP has been prepared to comply with its requirements, including updated SSO reporting protocols, triennial audit requirements, and performance monitoring expectations.

An SSMP describes the activities an agency undertakes to manage its wastewater collection system effectively. At a minimum, it addresses the following:

1. Maintaining or improving the condition of the collection system infrastructure to provide reliable service;

2. Cost-effectively minimizing inflow and infiltration (I&I) and providing adequate capacity to accommodate peak flow conditions; and

3. Minimizing the frequency and impact of sanitary sewer overflows.

This SSMP has been prepared to meet the requirements of both the SWRCB Order WQ 2022-0103-DWQ and the North Coast Regional Water Quality Control Board (RWQCB). It incorporates findings and corrective actions from the 2022–2025 Triennial SSMP Audit completed in October 2025 and integrates the 2025 Sewer Master Plan Update (PACE Engineering), adopted by the Board of Directors in February 2026.

Document Organization
This SSMP is organized into eleven elements as required by Order WQ 2022-0103-DWQ. Each element is presented as an integrated narrative section that describes program requirements, documents current practices, and identifies applicable supporting materials and appendices. The eleven elements are:

All revisions are logged in the SSMP Change Log (Appendix 10.D). 9 / 352
District Service Area and Sewer System
The City of Lakeport Municipal Sewer District (CLMSD or District) provides wastewater collection service to the City of Lakeport and adjacent unincorporated areas to the south and west. The City operates under a council-manager form of municipal government. The District is governed by a Board of Directors whose members also serve as the City Council.

Lakeport is located on the western shore of Clear Lake in Lake County. It was incorporated in 1888 and encompasses approximately 2.7 square miles. The District serves approximately 2,200 connections and over 5,000 customers, representing roughly eight percent of Lake County's total population. Current land use in Lakeport is approximately 76 percent commercial and residential, five percent industrial, and 19 percent open space, governmental, and agricultural.

The District operates and maintains the sanitary sewer collection system up to each private property line, along with eight sewage lift stations and a secondary wastewater treatment and disposal facility. A summary of key system metrics, as documented in the 2025 Sewer Master Plan Update, is provided below:

System Component Metric Source
Gravity sewer mains 30.23 linear miles 2025 SMPU
Force mains (estimated) 2.4 linear miles Distance measured using the system map
and electronic map

2025 SMPU
WWTP design capacity (ADWF) 0.53 MGD 2025 SMPU
Current ADWF (2020–2024 average) 0.36 MGD (68% of capacity) 2025 SMPU The collection system includes pipes ranging from 4 to 24 inches in diameter, with a significant portion of the infrastructure nearly 80 to 100 years old. While the system generally performs adequately under normal conditions, portions of the collection system are subject to moderate to severe surcharging during peak wet weather events due to inflow and infiltration (I&I). Ongoing I&I mitigation and targeted rehabilitation, guided by the 2025 Sewer Master Plan Update, are central components of the District's long-term asset management strategy.

The District's collection system discharges to a secondary wastewater treatment and disposal facility operated by the City.

Wastewater treated at the facility is disposed of through land application at the City's effluent irrigation areas. The Lake County Sanitation District (LACOSAN) maintains a mutual aid agreement with CLMSD, allowing for inter-agency flow exchange in both the northern and southern portions of the service area. 10 / 352
Purpose of This SSMP
The purpose of this SSMP is to provide a structured, continuously improving framework for the management, operation, and maintenance of the City of Lakeport's sanitary sewer collection system. The SSMP is designed to minimize sanitary sewer overflows, protect public health and water quality in the Clear Lake watershed, maintain system reliability, and ensure that infrastructure capacity is adequate to serve existing and future customers.

This plan update reflects a significant program modernization effort. It incorporates the corrective actions identified in the 2022–2025 Triennial SSMP Audit, integrates the adopted 2025 Sewer Master Plan Update as the District's current capacity and capital improvement planning foundation, and enhances formal performance monitoring, documentation, and operator participation frameworks.

This SSMP has been prepared by the City of Lakeport Compliance Officer and reviewed by the Utilities Director. Upon finalization, it will be certified in the California Integrated Water Quality System (CIWQS) by the Compliance Officer, who is authorized to certify SSO reports on behalf of the CLMSD Director.

This document is maintained on file at the City of Lakeport Utilities Department and is available for public inspection upon request. It will be made available to the State Water Resources Control Board or the Regional Water Quality Control Board upon request, consistent with the requirements of Order WQ 2022-0103-DWQ.

Operator input was solicited during the development of this revision, consistent with the participation requirements of Order WQ 2022-0103-DWQ. Documentation of operator participation is retained in Appendix C. 13 / 352
Element I — Goals
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee must develop goals to properly manage, operate, and maintain all parts of its sanitary sewer system in order to reduce and prevent SSOs, as well as to mitigate any SSOs that do occur.

1.1 Purpose and Mission
Safe, reliable, and environmentally responsible sewer service is a core function of the City of Lakeport Municipal Sewer District. The District's mission is to provide these services while protecting Clear Lake and the surrounding environment, maintaining high-quality customer service, and supporting the long-term economic vitality and livability of the City of Lakeport.

The District's mission statement reflects this commitment:
"The District is dedicated to fostering a safe and picturesque environment that enhances the quality of life for our community; it is our responsibility to promote the health and safety of City residents and visitors. We are committed to being responsive to the needs of the community, exercising innovation in sustaining and growing a vibrant place in which to live, work, and do business."

1.2 Program Goals
In support of this mission, the District has established the following goals for the management, operation, and maintenance of its wastewater collection system. These goals reflect both the requirements of Order WQ 2022-0103-DWQ and the District's commitment to continuous improvement in system performance and regulatory compliance. • Minimize sanitary sewer overflows (SSOs) and mitigate the impacts of any SSOs that do occur. • Prevent public health and environmental hazards, with particular attention to the protection of Clear Lake. • Maintain adequate conveyance capacity with a minimum of inflow and infiltration (I&I), consistent with the 2025 Sewer Master Plan Update.
• Implement a risk-based rehabilitation and capital improvement program to address aging infrastructure and extend the useful life of collection system assets.
• Reduce fats, oils, and grease (FOG) contributions to the collection system through active inspection, outreach, and enforcement.
• Respond to SSOs and service interruptions promptly and effectively, minimizing impacts to customers and the environment.
• Use available operations, maintenance, and capital funds in an efficient and accountable manner. • Perform all operations safely to protect the health and wellbeing of District staff, contractors, and the public. • Institutionalize data-driven performance monitoring and continuous program improvement through annual KPI review and triennial SSMP audits.
14 / 352

1.3 Performance Measures and Key Performance Indicators The 2022–2025 Triennial SSMP Audit identified the absence of measurable performance indicators as a primary basis for Element I non-compliance. To address this finding, the District has established a formal Key Performance Indicator (KPI) framework tied directly to the goals listed in Section 1.2. KPIs are tracked using CIWQS data, the District's SSO Tracking Spreadsheet, OpenGov EAM work order records, and the adopted 2025 Sewer Master Plan Update.

KPI performance is reviewed quarterly for incident-level metrics and annually for program-level metrics. Results are documented in the SSMP Change Log and inform adjustments to the preventive maintenance program, CIP prioritization, FOG enforcement, and other program activities. Annual review findings are reported to the Utilities Director.

Note: KPIs 3 and 5 below are based on trend tracking at this time. As the updated SSO Tracking Spreadsheet accumulates additional years of data, specific numeric benchmarks will be established during the annual performance review cycle. KPIs 5 and 6 are most meaningful as multi-year trends given the relatively low annual SSO frequency in the system.

1.4 Performance Review and Adaptive Management
KPI results are reviewed on the schedule described in Table 1.1 and formally compiled in an annual performance summary.

The annual review is conducted by the Compliance Officer and presented to the Utilities Director. Findings from the review directly inform program adjustments, including:
• Modifications to the preventive maintenance program and priority cleaning schedule (Element IV); • Updates to FOG inspection priorities and enforcement activity (Element VII); • Adjustments to CIP project sequencing or scope based on system performance data (Element VIII); • Revisions to SSO response protocols based on response time or recovery trends (Element VI); and • Updates to the SSMP itself, logged in the Change Log (Appendix 10.D).

This adaptive management approach ensures that the SSMP remains a living, responsive document rather than a static compliance artifact. Where KPI data indicates a trend in the wrong direction over two or more consecutive review periods, 16 / 352
the Compliance Officer will initiate a formal program review and document corrective actions in the CAP log (Appendix

10.C).

1.5 Plan Updates
This SSMP is updated following each triennial audit cycle or in response to significant changes in system conditions, organizational structure, regulatory requirements, or planning foundations. The next scheduled update is due following the 2025–2028 triennial audit cycle.

The 2025 Sewer Master Plan Update (PACE Engineering, February 2026) serves as the District's current capital and capacity planning foundation and is recommended by the engineer for re-evaluation within ten years. Any material update to the Master Plan that affects capacity assumptions, CIP priorities, or design criteria will trigger a corresponding SSMP update to Elements I, VIII, and IX.

1.6 Risk Management and Worst-Case Scenario Planning
The District acknowledges the following primary system risks, each of which is addressed through a corresponding program element or capital improvement:

Risk Current Condition Addressed By
High I&I during wet weather
events
PWWF reached 77% of design
capacity (Feb 2019). Flows can
exceed 8x ADWF during peak rain
events.
2025 SMPU I&I reduction

2.5 Training and Documentation
All key personnel identified in this element are trained in the SSO reporting and response communication chain. Training is documented, and sign-in sheets are retained in the Compliance Department records. Personnel responsible for CIWQS certification receive orientation on reporting requirements and authorized representative protocols upon assignment to that role.

The contact list and organizational chart are reviewed annually by the Compliance Officer or immediately upon any staffing change affecting SSMP responsibilities. Any staffing changes affecting SSMP responsibilities are reflected in the contact list and logged in the SSMP Change Log (Appendix 10.D) within 30 days of the change. 20 / 352
Element III — Legal Authority
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee's SSMP must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to: (1) prevent illicit discharges; (2) require proper design and construction of sewer connections; (3) ensure access for maintenance, inspection, and repairs to publicly owned portions of laterals; (4) limit the discharge of FOG and other debris that may cause blockages; and (5) enforce violations of its sewer ordinance.

3.1 Primary Legal Authority — Lakeport Municipal Code Chapter 13.20 The primary legal authority for CLMSD's operation of the sanitary sewer collection system is established under Lakeport Municipal Code (LMC) Chapter 13.20, Sewer Use and Pretreatment Regulations, adopted pursuant to Ordinance No. 872.

Under LMC Chapter 13.20, any residence or facility within the boundaries of CLMSD is required to connect to the municipal sanitary sewer system, with limited exceptions.

LMC Chapter 13.20 defines the authority and mechanisms granted to CLMSD to ensure that discharges to the collection and treatment system are not harmful to the environment or destructive to existing infrastructure. It establishes specific discharge regulations, pretreatment standards, and prescribed enforcement actions, and it provides the legal foundation for the District's Fats, Oils, and Grease (FOG) Control Program and Sewer Lateral Certificate Program. Key provisions include requirements for grease traps and interceptors to be installed and maintained by all users who produce or discharge FOG.

LMC Chapter 13.20 is currently under review for comprehensive revision. The update will modernize FOG enforcement provisions, update penalty schedules to reflect current economic conditions, and clarify inspection and industrial user program authority. A revision timeline will be established upon formal engagement with the City Attorney. The FOG program update is described in further detail in Element VII.

A complete copy of LMC Chapter 13.20 is included in Appendix 3.A. Supporting documents referenced in this element include:
• Fines for Violation of the FOG Program — Resolution No. 2315 (2008) (Appendix 3.B) — currently under review for update
• Utilities Department Policies U-3, U-4, and U-6 (Appendix 3.C) • Mutual Aid Agreement with Lake County Sanitation District — LACOSAN (Appendix 3.D)

3.2 Authority to Prevent Illicit Discharges and Control I&I LMC Chapter 13.20 requires that all identified sources of inflow and infiltration (I&I) be corrected upon discovery. The District actively investigates I&I sources and continuously works to identify and track new sources. While significant fiscal constraints have historically limited the pace of I&I correction, the adopted 2025 Sewer Master Plan Update establishes a prioritized I&I reduction program targeting the highest-impact areas of the collection system. I&I sources and rehabilitation needs identified through CCTV inspection and flow monitoring are tracked in the District's asset management and GIS records.

CLMSD is also granted permit authority under LMC Chapter 13.20 to regulate discharge from nondomestic industrial users, classified as Class I through IV under LMC Section 13.20.290. A formal industrial user survey has not been conducted to 21 / 352
date. Based on a preliminary review of commercial land uses in the service area, the District has identified several nondomestic user categories that may warrant formal classification under the LMC, including auto body and collision repair facilities, automotive service operations, dry cleaning establishments, a local environmental testing laboratory, and potentially metal fabrication or machining operations. These user types may be subject to federal categorical pretreatment standards under 40 CFR Subchapter N, depending on their specific processes and discharge characteristics. As a corrective action from this revision, the Compliance Officer will conduct a nondomestic user survey to identify, characterize, and appropriately classify nondomestic users connected to the CLMSD system. The survey will cross-reference the City's business license database and building permit records against the LMC classification criteria. Any users identified as Class I or II will be notified and required to apply for a wastewater discharge permit consistent with LMC Section 13.20.300. Target completion of initial survey: Q4 2026. Permitting to follow survey completion: target Q2 2027.

3.3 Rights of Entry
LMC Section 13.20.340 provides CLMSD personnel with the legal right to inspect connections, appurtenances, and other components of the municipal sanitary sewer collection system on private property where illicit discharges are known or suspected. Persons or occupants of premises where wastewater is generated or discharged shall allow the District or its authorized representative ready access to all parts of the premises for inspection, sampling, compliance monitoring, and records examination. Users must allow access during regular business hours with appropriate notice.

The Compliance Officer is responsible for ensuring these access rights are exercised appropriately and that the public is informed of their obligations under the ordinance.

3.4 Enforcement Mechanisms
The enforcement mechanisms available to CLMSD for violations of LMC Chapter 13.20 include, in order of escalation:

1. Informal administrative action, including notices of violation and written warnings

2. Administrative orders, compliance schedules, and other corrective action directives

3. Fines and fees

4. Penalties for non-compliance

5. Assessment of charges for damage to CLMSD facilities or operations

6. Suspension or termination of sewer service

7. Civil action

8. Criminal action
Fines related to the general provisions of the Sewer Use regulations can range from $300 to $1,000 per day per violation, depending on the nature of the infraction. The applicability and severity of fines are at the discretion of the Utilities Director or designee. Resolution No. 2315 (2008) (Appendix 3.B) prescribes specific fines and fees for violations or noncompliance with FOG program provisions. This resolution is currently under review for update as part of the LMC Chapter 13.20 revision effort, with the intent to align penalty levels with current enforcement practice and economic conditions.

3.5 Construction and Design Standards
Through resolution and by reference in the Lakeport Municipal Code, the City has adopted the California Plumbing Code (California Code of Regulations, Title 24, Part 5) as its standard for sewer construction and connections. The City has also adopted sewer infrastructure construction and design standards, which are discussed in Element V and referenced in Appendix 5.
22 / 352

3.6 Interagency Agreements
CLMSD maintains a mutual aid agreement with the Lake County Sanitation District (LACOSAN). Under this agreement, wastewater flows in the northern portion of the CLMSD service area can be directed to the County's collection system when needed. Conversely, wastewater flows from County areas south of the CLMSD collection area are accepted by CLMSD.

This agreement supports system resilience and provides operational flexibility during high-flow or emergency conditions. A copy of the agreement is included in Appendix 3.D.
23 / 352
Element IV — Operations and Maintenance Program
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee's SSMP must include: (1) maintenance of up-to-date collection system maps; (2) a preventive O&M program with scheduled cleaning and increased frequency at known problem areas; (3) a rehabilitation and replacement plan to identify and prioritize deficiencies; (4) a training program for staff and contractors; and (5) an equipment and critical replacement parts inventory.

Implementation Status — In Progress
The program framework and standards are documented in this revision. Full field implementation of the GIS edit log, standardized manhole inspection cadence, CCTV-to-asset-record integration, and critical spares tracking program is ongoing. Target: Q4 2026.

4.1 System Description and Asset Inventory

4.2 Collection System Mapping and GIS Records
The District maintains an Esri-based GIS map of its wastewater collection system, including all gravity mains, manholes, lift stations, force mains, pressure pipes and valves, and known stormwater connections. GIS mapping and system record updates are performed by an outside vendor under the direction of the Utilities Department. Field staff submits map correction requests and new asset information directly to the Compliance Officer, who logs each request in the GIS Edit Log and forwards them to the Utilities Director for submission to the GIS vendor. The Compliance Officer records completion on the log once updates are confirmed incorporated.

GIS Map Edit Log
A one-page Map Edit Log is maintained by the Compliance Officer capturing: date, asset ID, description of change, information source, requesting staff, and approver. The GIS vendor incorporates edits quarterly. The log is reviewed each quarter to confirm all pending updates are processed and filed in Compliance Department records.

Emergency Map Pack
An offline Emergency Map Pack of PDF map tiles covering all lift station service areas and high-risk segments is under development for field tablets and mobile devices. Updated at a minimum annually and whenever significant system changes occur, ensuring field access to current maps when internet connectivity is unavailable.

4.3 Preventive Maintenance Program
All preventive maintenance is planned and tracked in Enterprise Assest Management, the District's system of record for work orders, asset condition, and maintenance history. The Utilities Department underground crew or contracted construction crews perform routine and emergency repairs, including sewer replacements, spot repairs, lateral and service tap replacements, and manhole repairs.

Quarterly Priority Cleaning Program
Gravity main cleaning is performed on a routine quarterly basis throughout the collection system. Cleaning is conducted by hydraulic methods; mechanical methods are used where hydraulic cleaning is insufficient. Known problem locations, including areas with recurring root intrusion, FOG accumulation, or prior SSO history, are prioritized within the quarterly schedule. Cleaning activities are tracked in EAM by work order. The priority cleaning list is also maintained as a laminated reference in the crew room. EAM generates work orders automatically when scheduled cleaning is due.

4.4 Inspection and Condition Assessment
Systematic inspection is a core O&M program component. Inspection findings drive maintenance prioritization, rehabilitation planning, and GIS record updates. Three primary inspection methods are used.

Visual Inspections
Performed on manholes and accessible components during routine field activities. Covers: frame and cover condition, flow surcharging, manhole channel condition, structural integrity, I&I evidence, debris or grease in line, and miscellaneous defects. Staff document and report deficiencies to supervisors for OpenGov EAM work order entry.

CCTV Inspection
CCTV inspection is conducted by Utilities Division field staff as a field assessment tool in response to blockages, SSO events, and suspected deficiencies. Between 2018 and 2025 approximately 44,000 LF of the collection system was inspected by CCTV (Source 2025 Sewer Master Plan Update) Findings are documented in OpenGov EAM work orders and SSO reports as narrative observations. Stored video and systematic defect coding are not currently part of the standard inspection workflow. Development of a formal CCTV records retention practice is a program improvement target; see Appendix 10.C.

Manhole Inspection Program
Development of a systematic program targeting ~100 manholes/year for full system-wide coverage of all 568 manholes over five years. Findings will be linked to manhole asset records in OpenGov EAM. The Compliance Officer to maintain a tracking dashboard (inspected / defects found / repaired) reviewed quarterly, with full integration target Q4 2026.

4.5 Lift Station Operations and Preventive Maintenance
The District operates eight sewage lift stations: Lakeshore Boulevard, Rose, Clear Lake, C Street, Martin Street, Lakeport Boulevard, Larrecou, and Linda Lane. All stations have flow meters and one spare backup pump. Stations without stationary generators are equipped with connector plugs and manual transfer switches (MTSs) for rapid portable generator connection.

All stations and the WWTP are monitored via the 2024-upgraded SCADA system with a dedicated server, PLCs, cellularbackup radios, and VPN remote access.

Tier 1 / 2 / 3 Preventive Maintenance
Lift stations follow a rotating Tier 1–3 PM program. Tier 1: alarm test. Tier 2: flows and pump run with float checks.

Tier 3: site housekeeping. Tier 1 and Tier 2 activities are documented on hardcopy forms. Electrical maintenance (EMT) and amp readings are conducted annually by the Electrical Maintenance Technician (EMT) and documented separately. The long-term goal is to migrate all PM records into EAM.

4.6 Rehabilitation and Replacement Plan
The 2025 Sewer Master Plan Update (PACE Engineering, February 2026) serves as the District's rehabilitation and CIP planning foundation, superseding the 2008 Master Sewer Plan. Repair methods include point repairs, CIPP lining, slip lining, and full replacement, selected by defect type, pipe size, access constraints, and cost-effectiveness. 2025 SMPU Near-Term Rehabilitation Priorities
• 53 locations recommended for spot repairs
• 1,300 LF of pipeline recommended for replacement
• 4,500 LF of pipeline recommended for lining
• I&I reduction program — ~$3.2M targeting ~0.9 MGD reduction • Bypass connection installations at all 8 lift stations • Chlorination at Larrecou; dichlorination at Linda Lane 26 / 352
Rehabilitation & Replacement
Rehabilitation and replacement priorities are currently informed by the 2025 Sewer Master Plan Update (PACE Engineering, February 2026), which identifies system deficiencies and establishes long-term capital improvement priorities. Near-term decisions are guided by pipe age and material, SSO history, and field observations documented in OpenGov EAM. A formal risk-based prioritization framework is under development; target implementation Q1 2027, pending completion of systematic CCTV-to-asset-record integration.

Recently Completed Projects (2022–2025)
• 2024: Water/Sewer Main Replacement — 2,760 LF sewer main, 27 service laterals • 2024: SCADA upgrade — dedicated server, updated PLCs/radios, VPN remote access • 2024: Martin Street sewer upgrades
• 2025: Sodium hypochlorite conversion at WWTP (In Progress)

4.7 Training Program
All wastewater collection system personnel, except operator trainees, are required to hold a minimum Grade I (G1) wastewater operator certification. The WWTP is a Grade II facility requiring a chief operator with at least Grade II (G2) certification. All certifications must be maintained without interruption with all continuing education requirements met. As a small agency, Public Works staff from other divisions may assist with major SSO responses and receive applicable training.

Training Program Components
• Injury and Illness Prevention Program (IIPP) — formal safety policies reviewed and updated as required • Workplace safety tracking service — training reminders, completion records, and safety materials • Regularly scheduled Public Works safety meetings with job-specific training for Utilities Division staff • Annual SSO response training: spill volume estimation, cleanup practices, and CIWQS reporting procedures • Confined space entry policy review and CalOSHA compliance • SDS review prior to use of new chemicals
• Operator certification renewals and continuing education • Class B DMV license and CPR/First Aid certification renewals Training Matrix (In Development)
A training matrix identifying roles, courses, and minimum frequency is being developed. It will document annual SSO response and confined space refreshers as baseline requirements. Goal: at least 2 staff holding CWEA Collection System Maintenance Grade I within 24 months of SSMP adoption. Contractor sign-backs for SSO reporting procedures are filed with each project and copied to the internal safety coordinator.

4.8 Equipment, Critical Replacement Parts, and Recordkeeping The District maintains essential equipment, including a vacuum/Vactor truck, CCTV equipment, portable generators, bypass pumps, backhoes, dump trucks, router/snake, gas detectors, confined space entry equipment, and PPE. Smaller tools and PPE are stored in service vehicles for immediate field access. Larger assets including emergency generators are housed at the Corporation Yard.
27 / 352
Critical Spare Parts Program (In Development)
A critical spares list is being developed per lift station and pump model, identifying minimum on-hand quantities and reorder points. Quarterly inventory counts will be recorded in EAM. Where feasible, a monthly standby pump start/swap check is performed and documented. This formalizes what has historically been managed through visual monitoring and vendor account ordering.

Recordkeeping and Documentation
Enterprise Asset Management by OpenGov is the system of record for all asset tracking, PM work orders, inspection findings, equipment inventory, and maintenance history. All O&M records are retained per the District's records retention policy and made available to the SWRCB, RWQCB, or their representatives upon request. The GIS Edit Log (Appendix

4.A) documents a list of all updates to the collection system GIS. 28 / 352
Element V — Design and Performance Provisions
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee must: (1) identify design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations, and other appurtenances, and for the rehabilitation and repair of existing sanitary sewer systems; and (2) identify procedures and standards for inspecting and testing new sewers, pumps, and other appurtenances, and for rehabilitation and repair projects.

5.1 Design and Construction Standards
CLMSD's design and construction standards for the sanitary sewer collection system are established through two complementary frameworks: the California Uniform Plumbing Code (California Code of Regulations, Title 24, Part 5), which sets minimum statewide standards for all sewer construction; and the City of Lakeport's adopted Sewer System Design and Construction Standards (Appendix 5), which provide additional detail and requirements specific to the CLMSD system.

The adopted design standards apply to all new construction, rehabilitation, and improvements that will be dedicated to the public and accepted by CLMSD for maintenance or operation. They are also posted on the City's website for access by engineers, contractors, and property owners. The City Engineer is responsible for maintaining the standards and specifications and for ensuring compliance by both City construction crews and private third-party contractors.

All improvements within City rights-of-way must be installed in accordance with the City's adopted improvement plans and specifications at the City Engineer's discretion. New sanitary sewer system installations, pump stations, and appurtenances are designed and constructed to meet the area’s service needs and conform to these adopted standards.

Standard / Authority Scope and Application
California Uniform Plumbing Code
(CCR Title 24, Part 5)
Minimum statewide standards for all sewer construction, adopted by reference in the Lakeport Municipal Code.

CLMSD Sewer System Design and
Construction Standards (Appendix
5)
City-adopted standards providing additional requirements for new construction, rehabilitation, and improvements including service laterals, cleanouts, manholes, rodding inlets, and private lift station discharge lines.

LMC Section 13.20.190
Connection Requirements
Requires all connections and modifications to the sanitary sewer to be reviewed and approved by CLMSD as a condition of the building permit.

LMC Section 13.20.320.F Sewer
Lateral Certificate Program
Establishes triggering events that require cleaning, inspection, and testing of private sewer laterals before a sewer lateral certificate of compliance is issued.

5.2 Connection Requirements and Approval Process
All connections and modifications to the CLMSD sanitary sewer system require review and approval as a condition of the requisite building permit, consistent with LMC Section 13.20.190. The Chief Building Official is responsible for evaluating proposed new connections and ensuring they meet all applicable design and construction standards prior to approval. This review provides a critical point of control to prevent substandard connections that could contribute to I&I or future SSOs. 29 / 352
Any residence or facility within CLMSD boundaries is required to connect to the municipal sanitary sewer system, with limited exceptions as provided in LMC Chapter 13.20. New public lift stations are designed and constructed to meet the specific capacity and service needs of the area being served.

5.3 Inspection and Testing Procedures
CLMSD employs a combination of inspection and testing methods for new construction, rehabilitation projects, and private sewer laterals. The selection of method is based on the type of infrastructure, project scope, and field conditions. The following methods are used:

Method Application Authority / Notes
Smoke testing Primary method for inspecting public
sewer mains and cleanouts in the public
right-of-way; identifies open cleanouts,
leaking manholes, and damaged sewers.

Routine and I&I investigation use;
conducted by field crews.

CCTV inspection Used for public mains, cleanouts, and
private laterals where further investigation
is required beyond visual or smoke
testing. Also used for post-repair
verification.

Authorized by field supervisor,
Utilities Director, or Compliance
Officer. Follows NASSCO PACP
standards.

Visual inspection Cleanouts in the public right-of-way are typically inspected visually; used as a firstline assessment before escalating to CCTV.

Performed by field crews during
routine maintenance.

Dye testing Used to confirm results from visual
inspection; particularly useful for tracing
suspect connections or I&I sources.

Supplemental method; employed
as needed.

Hydrostatic pressure
testing
Rarely used for sewer components,
private or public. Applied only in specific
circumstances where other methods are
insufficient.

Field crews; limited application.

5.4 Private Sewer Lateral Program
LMC Section 13.20.320.F establishes the framework for a Sewer Lateral Certificate of Compliance program. Under this framework, private sewer laterals are subject to cleaning, inspection, and testing upon the occurrence of specific propertyevent triggers, including building permit applications for significant remodels, change of use, installation of additional toilet facilities, main sewer repair or replacement, and account closures. The program has been in place since Ordinance No. 872 was adopted in 2008.

Few Sewer Lateral Certificates of Compliance have been issued since adoption. Implementation of mandatory trigger-based inspections has been inconsistent due to staffing constraints and limited inter-departmental coordination at the permit counter. Active mandatory enforcement of the program as currently written is not being pursued at this time. 30 / 352
The program framework will be re-evaluated as part of the comprehensive LMC Chapter 13.20 revision described in Element III. That revision will assess whether the current trigger structure, certificate terms, and administrative roles remain appropriate given staffing capacity and program design considerations.

Proactive I&I Education — Permit Counter Fact Sheet
As a proactive interim measure to inform property owners of their lateral responsibilities, a plain-language lateral condition fact sheet is being developed for distribution at the permit counter to all building and plumbing permit applicants. The fact sheet will describe: private lateral owner maintenance responsibilities under the LMC; common signs of lateral failure; the relationship between lateral condition and I&I; and how to request a voluntary inspection. Target completion: Q3 2026.

5.5 Inspection SOPs — Program Improvement
The 2022–2025 Triennial Audit found Element V compliant and noted that the combination of smoke testing, CCTV, visual inspection, and dye testing provides a robust and proactive program. The audit recommended formalizing the specific circumstances under which each inspection method is applied by documenting a Standard Operating Procedure (SOP) for new construction and rehabilitation inspections, to ensure consistency across all projects and field crews.

A Design and Construction Inspection SOP is being developed by the Compliance Officer in coordination with the City Engineer and field supervisors. The SOP will document: the trigger conditions for each inspection method; applicable standards (NASSCO PACP, California Plumbing Code); documentation requirements; and sign-off authority for new construction and rehabilitation project acceptance. Target completion: Q3 2026. 31 / 352
Element VI — Overflow Emergency Response Plan
Regulatory Requirement — Order WQ 2022-0103-DWQ
Each enrollee shall develop and implement an Overflow Emergency Response Plan (OERP) that identifies measures to protect public health and the environment, including: (1) proper notification procedures; (2) a program to ensure appropriate response to all SSOs; (3) prompt notification to regulatory agencies and affected entities; (4) procedures to ensure staff and contractors are trained; (5) procedures to address emergency operations including traffic and crowd control; and (6) a program to contain and minimize adverse environmental impacts from SSOs.

Implementation Status — Compliant with Deficiencies
The OERP framework is well-developed and operationally sound. Corrective actions from the 2022–2025 Triennial Audit address three specific gaps: real-time response time-stamping, formalized annual drill documentation, and a post-spill review process. These improvements are underway and documented in Sections 6.4, 6.5, and 6.6 below.

6.1 Overflow Emergency Response Plan — Overview
CLMSD's Overflow Emergency Response Plan (OERP), effective August 3, 2023, is the District's primary governing document for sanitary sewer overflow detection, response, containment, cleanup, and notification. The OERP is maintained as Utilities Division Policy U-11 and is included in Appendix 6.C. Copies are kept in policy binders at Public Works and Utilities sites and on the City’s Safety SharePoint.

The OERP establishes a 24-hour emergency contact system, delineates the chain of command for internal and external notifications, and provides detailed field guidance covering: first responder assessment; overflow correction, containment, and cleanup; traffic and pedestrian control; water quality monitoring and sampling; and spill volume estimation methods.

The District also maintains a Hazardous Materials Incident Response Plan (Appendix 6.B), which governs response to major emergencies involving chemical spills or uncontrolled releases threatening public health.

Supporting documents referenced in this element include:
• SSO Notification and Reporting Forms (Appendix 6.A)
• Hazardous Materials Incident Response Plan (Appendix 6.B) • SSO Emergency Response Plan — Utilities Division Policy U-11 (Appendix 6.C) • SSO Regulatory Reporting Requirements Reference Guide (Appendix 2.B)

6.2 Notification Procedures
CLMSD staff respond immediately to any report of an SSO or sewer system malfunction. Incident reports may come from any source —resident, business owner, law enforcement, fire, or SCADA alarm—and are typically received by telephone.

A 24-hour public emergency telephone number is maintained and posted on the City's website. 32 / 352

5 For Category 1 SSOs (≥1,000 gallons
reaching a drainage channel or surface
water): CLMSD Director / City Manager
notified immediately
Utilities Director or designee notifies Kevin Ingram
External notification requirements vary by SSO category and are detailed in the SSO Regulatory Reporting Requirements Reference Guide (Appendix 2.B). At minimum, all SSOs are reported through CIWQS consistent with Order WQ 2022- 0103-DWQ. Category 1 SSOs additionally require notification to the Regional Water Quality Control Board, CalOES, the Lake County Environmental Health Department, and any potentially affected water suppliers. The Compliance Officer is authorized to submit all required notifications and reports on behalf of the CLMSD Director.

6.3 Response Program and Field Operations
Upon arrival at the scene, field staff conduct an initial assessment to determine the source, estimated volume, extent of spread, and potential for the spill to reach a drainage channel or surface water. The Field Staff Spill Report form (Appendix

6.A) is completed in the field during the active response and documents key data, including: time of arrival, source location, estimated volume, containment actions taken, and cleanup methods used.

Response activities follow the protocols established in the OERP (Appendix 6.C) and include: source identification and correction; containment using equipment such as vacuum trucks, sandbags, and wattles; cleanup and disinfection of affected surfaces; traffic and pedestrian control; and water quality sampling where the spill has reached or potentially reached a drainage channel or surface water. Field staff are equipped with spill response materials in service vehicles.

All gravity line blockages are followed by CCTV inspection to identify the cause and assess pipe condition. Inspection findings are documented in EAM and used to inform maintenance prioritization and rehabilitation planning.

6.4 Response Time Metrics — Program Improvement
The 2022–2025 Triennial Audit found that while the OERP requires time-based documentation of SSO response, three specific timestamps are not yet consistently captured: (1) initial notification time, (2) first responder arrival time, and (3) CalOES notification time. These parameters are essential for assessing response timeliness and demonstrating compliance with Order WQ 2022-0103-DWQ reporting requirements.
33 / 352
The SSO Tracking Spreadsheet (2025 Edition) has been expanded to include dedicated fields for all three timestamps. This update was implemented as a corrective action from the 2022–2025 audit. Going forward, all three fields are required entries for every SSO event record. The Compliance Officer reviews timestamp data at each quarterly SSO program review for completeness and to identify patterns in response interval performance.

6.5 Training and Drills
All Utilities Division staff and applicable Public Works personnel are required to complete SSO response procedures training.

Training is based on the City's adopted OERP policies, including spill volume estimation methods and reporting procedures.

Spill response activities and procedures are reviewed during regularly scheduled staff meetings.

Contractors performing work on the CLMSD collection and conveyance system are provided with the Sewer Spill Response Instructions for Contractors and are required to ensure all on-site personnel are trained on spill response procedures prior to beginning work. A signed Contractor Compliance Agreement acknowledging receipt of spill response instructions and acceptance of notification requirements is retained in the project file.

Annual Drill Program
A formal schedule for annual overflow response drills has been established, consistent with the 2022–2025 audit corrective actions. The most recent full-staff OERP training was conducted in 2023 with attendance documented via sign-in sheets. A refresher training and full-scale drill are scheduled for mid 2026. Each drill is documented with: scenario description, participant list, and a written lessons-learned summary. Documentation is retained in Compliance Department records and used to inform training updates and procedure refinements.

6.6 Post-Spill Review and Continuous Improvement
Following each SSO event, an after-action review is conducted with all staff who participated in the spill response, as feasible.

The review covers: incident timeline, root cause, containment and cleanup effectiveness, regulatory notification compliance, and lessons learned. Findings are documented in a written after-action summary, which is filed with the original spill reporting documentation in the event-specific project file.

Recurring issues or systemic findings identified through after-action reviews are used to update training content, refine OERP field procedures, and inform maintenance and rehabilitation priorities. Significant findings are discussed with the Utilities Director and incorporated into the annual SSMP performance review under Element IX.

Continuous Improvement Integration
Enhanced response metrics and post-spill review data are incorporated into annual SSMP performance reviews and future triennial audits as evidence of continuous improvement and response efficiency, consistent with the 2022–2025 audit corrective actions. The SSO Tracking Spreadsheet, Post-Spill Review forms, and drill documentation together form the District's continuous improvement record for Element VI.

6.7 Hazardous Materials and Major Emergency Procedures
CLMSD maintains a Hazardous Materials Incident Response Plan (Appendix 6.B) that governs responses to emergencies involving chemical spills or uncontrolled releases. This plan applies to SSO events deemed major emergencies that threaten public health and may require evacuation and public notification. The plan is updated as required by state law, and copies are distributed to the Lake County Environmental Health Department and the Lakeport Fire District. 34 / 352
First responders for major emergencies include the Lakeport Police Department, Lake County Sheriff's Department, Lake County Office of Emergency Services, and the Lakeport Fire District. CLMSD staff are trained to limit their role during a declared major emergency to notification and evacuation only and are not to engage in other emergency response activities.

Copies of the plan are maintained at the surface water treatment plant, the Corporation Yard sewer office, and the wastewater treatment plant, and are available electronically on the city’s Safety SharePoint.

The City also maintains a general Emergency Operations Plan (EOP). The City Manager is responsible for implementing the EOP, managing overall City operations during a major emergency, and ensuring the plan is updated regularly and that staff receive adequate emergency operations training.

Element VII — Sewer Pipe Blockage Control Program
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program including: (1) public education and outreach; (2) FOG disposal plan; (3) legal authority to prohibit discharges; (4) grease removal device requirements and design standards; (5) inspection and enforcement authority; (6) identification of FOG-prone system sections and cleaning schedule; and (7) source control measures for identified FOG sources.

Implementation Status — Non-Compliant, Active Corrective Actions Underway The 2022–2025 Triennial Audit found this element Non-Compliant. The legal authority framework is in place under LMC Chapter 13.20, but the FOG program has been largely inactive due to outdated materials and limited staff capacity.

Significant corrective actions have been completed or are actively underway. This element documents the program framework as rebuilt and identifies commitments for full implementation. Target: operational compliance by Q4 2026.

7.1 FOG Problem Identification
FOG is confirmed as a recurring problem in the CLMSD collection system. During the 2022–2025 audit period, FOG blockages accounted for 22% of all SSOs, the second-leading cause, behind root intrusion (33%). FOG-related blockages are concentrated in older clay pipe sections where grease accumulates on pipe walls, particularly in areas with a high density of food service establishments (FSEs). A FOG control program is therefore required and is being actively implemented.

A preliminary FSE inventory has been compiled for this revision. Twenty-eight food service establishments have been identified in the CLMSD service area at this time. The inventory is being cross-referenced against City business license and connection records and will serve as the foundation for the trigger-based inspection program described in Section 7.8. The FSE compliance tracking spreadsheet is maintained by the Compliance Officer and will be updated as data is collected.

The GIS-based SSO incident map (Appendix 7.D) identifies system sections subject to FOG-attributed spills. FOG-attributed SSOs are flagged in the SSO Tracking Spreadsheet, enabling trend analysis at the quarterly SSO program review. These locations are incorporated into the priority cleaning schedule described in Element IV and are the primary targets for FOG source control measures.

7.2 Legal Authority
CLMSD's legal authority for FOG program regulation and enforcement is established under Lakeport Municipal Code (LMC) Chapter 13.20, Sewer Use and Pretreatment Regulations, adopted pursuant to Ordinance No. 872 (2008). Key provisions include:
36 / 352
LMC Section Authority / Provision
§ 13.20.010 Establishes objectives of the FOG program, including compliance with state and federal environmental protection laws.
§ 13.20.600 et seq. FOG program regulations, including prohibition of untreated FOG discharge to the municipal sewer system.
§ 13.20.610 Requires grease traps and interceptors at all FSEs that produce FOG; establishes design and sizing requirements.
§ 13.20.610.B Requires grease traps/interceptors at facilities producing substances harmful to CLMSD.
§ 13.20.390–13.20.500 Enforcement provisions ranging from informal notices to administrative penalties, civil action, and criminal enforcement.
§ 13.20.650 FOG program variance process for case-by-case exemptions. § 13.20.660 et seq. Wastewater discharge permit requirements for commercial and industrial users.

Ordinance Update — In Progress
LMC Chapter 13.20 is under comprehensive revision as described in Element III. The FOG ordinance provisions (§ 13.20.600 et seq.) will be modernized as part of this revision to ensure they are legally defensible and support current programmatic improvements including updated interceptor sizing standards, enforcement penalty schedules, and inspection triggers. The revised ordinance is being developed in coordination with the City Attorney. A revision timeline will be established upon formal engagement with the City Attorney.

7.3 Grease Removal Device Requirements
LMC Section 13.20.610 requires all FSEs that generate or work with FOG to install and maintain grease traps or grease interceptors. Design, sizing, maintenance, and recordkeeping requirements are established in the ordinance and further detailed in the Grease Trap/Interceptor Inspection Policy (Appendix 7.B).

Interceptor sizing is determined using the California Plumbing Code Section 1014.2 formula. A grease interceptor sizing calculator has been developed and is used by the Compliance Officer and Building Official to verify that proposed interceptor sizes meet the minimum required capacity based on fixture count, drain time, and waste flow rate. This tool replaced an outdated informal sizing process and is now the standard for all new interceptor installations and permit applications.

FSEs are required to maintain a cleaning and service log for their grease traps and interceptors. These records must be made available for inspection by the Compliance Officer, Building Official, or Lake County Environmental Health staff upon request. Cleaning and hauling must be performed by a licensed grease hauler, and disposal receipts serve as the primary documentation of compliance.

7.4 Inspection and Enforcement Authority
CLMSD staff hold the authority to inspect all grease-producing facilities and enforce the FOG provisions of LMC Chapter

13.20. The Compliance Officer and Chief Building Official are the primary administrators of the FOG program. Qualified Utilities Division field staff are available to conduct inspections at the direction of the Compliance Officer or Utilities Director. 37 / 352
FOG Inspector Certification — Complete
The Compliance Officer has completed FOG Inspector Certification, providing in-house inspection and enforcement expertise. This certification enables the District to conduct formal FSE inspections independently, reducing reliance on County Environmental Health coordination for routine enforcement. Certificate is on file in the Compliance Officer's training records.

County Environmental Health MOU — In Progress
A Memorandum of Understanding (MOU) with the Lake County Environmental Health Department is being developed.

Under the MOU, FOG inspections will be triggered when an FSE cannot produce grease disposal receipts at their annual County health inspection. This creates a coordinated enforcement mechanism that leverages existing County inspection activity to identify non-compliant FSEs without requiring a separate CLMSD inspection scheduling system. MOU execution target: 2027

7.5 Public Education and Outreach
CLMSD has operated a public education and outreach program for the FOG program since 2008, targeting both FSEs and residential users. Educational materials have historically been distributed to all FSEs upon application for a City business license and have been made available on the City's website. The City also uses social media platforms to supplement FOG education with reminders about proper grease disposal practices.

The existing educational materials date to 2009 and are being replaced as part of this revision cycle. An updated bilingual (English/Spanish) FOG education package is being developed, consisting of: a plain-language FSE fact sheet describing interceptor requirements, cleaning frequency, and disposal documentation; a residential best practices flyer covering drywiping, proper disposal, and the impacts of FOG on the sewer system; and a permit counter handout summarizing the FOG program for new business applicants. Target completion and launch: Q4 2026. Distribution will occur through the City website, permit counter, utility billing inserts, and direct distribution to FSEs during inspections.

FOG Permit Application and Hauling Log — Updated
A revised FOG permit application and hauling log have been developed as part of this program rebuild. The updated application captures FSE contact information, interceptor specifications, sizing calculations, cleaning schedule, and hauler information. It is designed to serve as both a permit application and an ongoing compliance record, and is available at the permit counter and on the City website. FSEs may also submit hauling records electronically; an online submission portal is under consideration to streamline record collection.

7.6 FOG Disposal
LMC Section 13.20.600 et seq. prohibits the discharge of untreated FOG to the municipal sanitary sewer system. FSEs are required to use licensed grease haulers to service their traps and interceptors and remove collected FOG. Hauling receipts serve as the primary compliance documentation and must be retained and made available for inspection.

FSEs that produce nominal amounts of FOG may be permitted to allow collected grease to solidify and dispose of it in the regular solid waste stream. This exception is limited and is evaluated on a case-by-case basis through the variance process under LMC Section 13.20.650. CLMSD encourages all FSEs and residential users to exercise best management practices 38 / 352
(BMPs), including dry-wiping dishes and cookware before washing and collecting frying oils in sealed containers for proper disposal.

7.7 FOG Identification and Cleaning Schedule
System sections subject to FOG-attributed spills are identified through the GIS-based SSO incident map (Appendix 7.D), CCTV inspection findings, and field crew observations. These locations are incorporated into the priority cleaning schedule in OpenGov EAM, ensuring higher cleaning frequency in FOG-prone segments. The cleaning schedule is reviewed quarterly and updated based on new SSO events, inspection findings, and changes in FSE density or activity in affected areas.

FOG-attributed SSOs are flagged in the SSO incident map and in the SSO Tracking Spreadsheet, enabling trend analysis at the quarterly SSO program review. This data directly informs FSE outreach priorities and cleaning schedule adjustments under the trigger-based inspection program described in Section 7.8.

7.8 Inspection and Enforcement Program
CLMSD is establishing a trigger-based FOG inspection program consistent with the agency's staffing capacity and the requirements of Order WQ 2022-0103-DWQ. The program does not rely on a routine annual inspection schedule for all FSEs. Instead, inspections are initiated by specific triggers that identify FSEs with actual or probable compliance issues, concentrating enforcement resources where they are most needed.

Inspection Trigger Description
County Environmental Health
MOU referral
FSE unable to produce grease disposal receipts at annual Lake County health inspection is referred to CLMSD for follow-up. Primary enforcement mechanism pending MOU execution.

FOG-attributed SSO Any SSO with FOG identified as cause triggers inspection of FSEs in the upstream drainage area.

New FSE permit application All new FSEs applying for a business license or building permit are subject to interceptor review and sizing verification prior to connection.

Complaint referral Complaints from public, other City departments, or County Environmental Health regarding FOG discharge or interceptor maintenance.

Director determination Inspection required by the Utilities Director or Compliance Officer for the protection of public health, safety, or welfare per LMC Section 13.20.290.

Enforcement actions available under LMC Chapter 13.20 range from informal notices of violation and compliance schedules to administrative civil penalties, civil action, and criminal enforcement. Resolution No. 2315 (2008) (Appendix 3.B) prescribes the current fine schedule for FOG program violations; this resolution is under review for update as part of the broader LMC Chapter 13.20 revision.

Element VIII — System Evaluation and Capacity Assurance Plan Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee shall prepare and implement a Capital Improvement Plan that provides hydraulic capacity for dry weather peak flow conditions and appropriate design storm or wet weather events. The plan must include: (1) evaluation of system portions experiencing or contributing to SSOs caused by hydraulic deficiency; (2) establishment of design criteria where deficient or absent; (3) capacity enhancement measures including a short- and long-term CIP with prioritization, alternatives analysis, and funding sources; and (4) a schedule for CIP completion.

Implementation Status — Restored to Compliance
The 2022–2025 Triennial Audit found this element Non-Compliant due to reliance on the outdated 2008 Master Sewer Plan.

The 2025 Sewer Master Plan Update (PACE Engineering) was adopted by the CLMSD Board of Directors in February 2026.

This SSMP revision incorporates the 2025 SMPU as the District's current system evaluation and capacity planning foundation, restoring compliance with this element.

8.1 System Evaluation Foundation — 2025 Sewer Master Plan Update The 2025 Sewer Master Plan Update (PACE Engineering, adopted February 2026) serves as CLMSD's current system evaluation and capacity assurance document. It replaces the 2008 Master Sewer Plan and includes updated flow-monitoring data, hydraulic computer modeling, condition-assessment findings, and a prioritized Capital Improvement Plan. The 2025 SMPU is included in Appendix 8.A is the authoritative source for all hydraulic data, design criteria, and CIP projects referenced in this element.

8.2 System Capacity and Design Criteria
The 2025 SMPU evaluated system capacity under existing, 10-year, and 20-year flow conditions. Key capacity metrics are summarized below:

Parameter Value Source
WWTP design capacity (ADWF) 0.53 MGD 2025 SMPU
Current ADWF (2020–2024 avg.) 0.36 MGD (68% of capacity) 2025 SMPU Peak wet weather flow (PWWF) 2.31 MGD (Feb 2019 peak
event)
2025 SMPU
PWWF:ADWF ratio 6.4:1 (significantly exceeds 3:1
design threshold)
2025 SMPU
Pipeline locations identified for spot repair 53 locations 2025 SMPU CCTV assessment
Pipe replacement recommended 1,300 linear feet 2025 SMPU Pipe lining recommended 4,500 linear feet 2025 SMPU
41 / 352

8.3 Hydraulic Deficiency Evaluation
I&I remains the dominant driver of peak wet weather flows. The PWWF:ADWF ratio of 6.4:1 significantly exceeds the typical design ratio, indicating that I&I reduction is the highest-priority hydraulic improvement. The 2025 SMPU identified 53 pipeline locations for spot repairs, with 1,300 linear feet requiring replacement and 4,500 linear feet recommended for lining.

Approximately 2.13% of the system is not readily accessible for maintenance, representing an ongoing operational constraint. Lift station capacity is generally adequate for existing flows, with targeted improvements needed at specific stations as detailed in the 2025 SMPU.

8.4 Capital Improvement Plan
The 2025 SMPU establishes a prioritized Capital Improvement Plan organized into three implementation periods. All cost estimates are in July 2025 dollars and include a 30% construction contingency and 35% indirect cost allowance.

Period Collection System WWTP Total
Immediate Term 2025–2030 $13,300,000 $710,000 $14,010,000 Near Term 2030–2035 $4,472,000 $165,000 $4,637,000
Long Term 2035–2045 $6,600,000 $31,086,000 $37,686,000
Total $24,372,000 $31,961,000 $56,333,000
The CIP is integrated with the risk-based rehabilitation prioritization framework described in Element IV. Projects are ranked annually by likelihood x consequence and maintained in OpenGov EAM. CIP delivery status and capacity outcomes are tracked quarterly by the Utilities Director and Compliance Officer. Near and long-term project details are provided in the 2025 SMPU Table ES-1 (Appendix 8.A).

8.5 I&I Reduction Program
I&I reduction is the single highest-priority capacity enhancement measure identified in the 2025 SMPU. The recommended I&I reduction program targets the high-I&I areas identified in flow monitoring data. The estimated program cost is approximately $3.2 million, with a projected reduction of approximately 0.9 MGD of I&I from the system, meaningfully reducing the PWWF: ADWF ratio and extending the useful life of existing collection system capacity. The City intends to continue wet-weather flow monitoring to verify I&I allowance estimates and refine rehabilitation priorities as new data become available.

8.6 Funding Strategy
The 2025 SMPU identifies the following primary funding sources for CIP implementation: Clean Water State Revolving Fund (CWSRF), Lakeport qualifies as a severely disadvantaged community, making it eligible for up to 100% grant funding for projects addressing a violation or septic-to-sewer components; Community Development Block Grants (CDBG); and City general fund and sewer enterprise fund revenues. The CIP is reviewed annually as part of the City budget process and updated to reflect project completions, new findings, and changes in grant funding availability.

The 2025 SMPU will be re-evaluated within 10 years, consistent with the recommendation in the plan. The next SMPU update is estimated for approximately 2035, or earlier if system conditions or growth rates change materially. Findings from this update will be incorporated into the subsequent SSMP revision. 43 / 352
Element IX — Monitoring, Measurement, and Program Modifications Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee shall: (1) maintain relevant information to establish and prioritize SSMP activities; (2) monitor the implementation and effectiveness of each SSMP element; (3) assess the success of the preventive maintenance program; (4) update program elements based on monitoring or performance evaluations; and (5) identify and illustrate SSO trends including frequency, location, and volume.

Implementation Status — Non-Compliant, Active Corrective Actions Underway The 2022–2025 Triennial Audit found this element Non-Compliant due to a stale SSO trends table (data only through 2017) and absence of a formalized performance review cycle. Significant corrective actions have been completed: the SSO Tracking Spreadsheet (2025 Edition) has been built and populated with historical data, and a quarterly review cadence has been established. Full integration of performance data into SSMP decision-making is ongoing. Target: full compliance Q3 2026.

9.1 Data Collection and Maintenance Records
CLMSD uses EAM as its electronic asset and operations management system. All preventive maintenance activities, corrective maintenance work orders, CCTV inspection findings, and lift station PM records are tracked in EAM. This system provides the data needed to prioritize activities and evaluate the effectiveness of the preventive maintenance program.

Maintenance records are reviewed by the Utilities Superintendent and field supervisors regularly to refine scheduling and identify emerging problem areas.

The GIS-based SSO incident map (Appendix 7.D) provides a spatial record of all SSO events, including location, cause, volume, and recovery status. The map is updated following each spill event and is used in conjunction with the SSO Tracking Spreadsheet and OpenGov EAM data to identify patterns and inform program adjustments.

9.2 SSO Tracking Spreadsheet
The SSO Tracking Spreadsheet (2025 Edition) is the District's primary tool for collecting, organizing, and analyzing SSO performance data. It captures date, time, location, estimated volume, cause code, recovery status, response timestamps, CIWQS report number, and post-spill review notes for every SSO event. Historical data has been backfilled from 2018 to the present as a corrective action from the 2022–2025 audit. The spreadsheet is the foundation for all SSO trend analysis and KPI reporting described in this element.

9.3 Quarterly Performance Review
The Compliance Officer conducts a quarterly performance review using data from OpenGov EAM, the SSO Tracking Spreadsheet, and program records. The review is documented in a one-page summary filed in the Compliance Department records. The following items are reviewed each quarter:
44 / 352

9.4 SSO Trend Analysis
SSO trend data is compiled annually from the SSO Tracking Spreadsheet and presented in the annual performance summary. Trends are evaluated for: total SSOs per year, SSO volume, cause code distribution (roots, FOG, debris, pump station, other), Category 1 events reaching surface water, and response time intervals. Trend findings directly inform PM program adjustments, FOG inspection priorities, CIP project sequencing, and OERP procedure updates as described in Element I Section 1.4.

9.5 Annual Performance Summary and Program Modifications Each calendar year, the Compliance Officer prepares an annual performance summary compiling KPI results, SSO trend data, and a review of each SSMP element's implementation status. The summary is presented to the Utilities Director and, where significant findings warrant, to the CLMSD Board of Directors. The annual review is the primary input to the triennial SSMP audit and ensures the SSMP remains a living document that accurately reflects current program conditions. 45 / 352

9.6 SSMP Change Log and Document Control
All revisions to the SSMP are recorded in the SSMP Change Log (Appendix 10.D). The log captures: date of change, element affected, description of the change, basis or trigger, and the name of the staff member making the change. Minor changes are approved by the Utilities Director. Significant changes are presented to the CLMSD Board of Directors for review. The Compliance Officer is primarily responsible for maintaining the Change Log. The Change Log is reviewed at each quarterly performance review to confirm completeness.

9.7 Using Performance Data to Drive Program Decisions
SSO trend data, maintenance records, KPI results, and post-spill review findings are actively used to inform decisions across all SSMP elements. The table below summarizes how performance data feeds into program adjustments:

Element X — Program Audits
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee shall conduct periodic internal audits appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every three years and a written report must be prepared and kept on file. The audit shall evaluate the effectiveness of the SSMP, assess the Enrollee's compliance with the General Order requirements, and identify any program deficiencies and steps to correct them.

Implementation Status — Restored to Compliance
The 2022–2025 Triennial Audit found this element Non-Compliant due to the absence of prior audit records on file. The 2022–2025 SSMP Audit Report (prepared October 2025, approved by Utilities Director Paul Harris) re-establishes compliance and provides the foundation for all future audit cycles.

10.1 Audit Program Overview
CLMSD conducts triennial internal audits of the SSMP consistent with Order WQ 2022-0103-DWQ. Each audit evaluates:
the effectiveness of the SSMP in preventing SSOs; compliance with the General Order requirements for each element; and program deficiencies and corrective actions needed. Audit findings are documented in a written report, approved by the Utilities Director, filed with the SSMP, and incorporated into the subsequent SSMP revision.

Operator input is solicited during each audit cycle consistent with Order WQ 2022-0103-DWQ requirements. Field staff, supervisors, and management are given the opportunity to review audit findings and provide input on corrective actions prior to the final report. Documentation of operator participation is retained in the Compliance Department records.

10.2 Current Audit — 2022–2025 Triennial Audit
The 2022–2025 Triennial SSMP Audit was conducted by the Compliance Officer and completed in October 2025. The audit evaluated SSMP compliance for the period May 2022 through May 2025 and identified corrective actions across multiple elements. The audit report was approved by Utilities Director Paul Harris and is on file in the Compliance Department records. All corrective actions identified in the audit are addressed in this SSMP Revision 5.

10.3 Corrective Action Tracking
Corrective actions identified through the triennial audit are tracked in the Corrective Action Program (CAP) Log (Appendix

10.C). The CAP Log captures: audit finding, element affected, corrective action committed, responsible party, target date, and completion status. The log is reviewed at each quarterly performance review and updated as actions are completed.

Significant deviations from committed targets are documented and reported to the Utilities Director.

Element XI — Communication Program
Regulatory Requirement — Order WQ 2022-0103-DWQ
The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The program shall provide the public the opportunity to provide input on the SSMP as it is developed and implemented. The Enrollee shall also create a plan for communicating with owners/operators of systems that connect into the Enrollee's system, including satellite systems, for system operation, maintenance, and capital improvement-related activities.

Implementation Status — Compliant with Deficiencies
The 2022–2025 Triennial Audit found active public communication channels in place but noted they were not described in the SSMP, and that no formal outreach calendar or public feedback intake process existed. This revision documents existing tools and commits to formalizing the outreach calendar and feedback process. Target: Q3 2026.

11.1 Public Communication Platforms
CLMSD communicates with the public about sewer system performance, SSMP content, and spill prevention through the following platforms:

Platform How It Supports SSMP Communication
City Website
(cityoflakeport.com)
Primary repository for SSMP documents, FOG program information, and regulatory notices. SSMP is posted following each revision. Updated by the Compliance Officer and IT Department.

Public Works Facebook Page Used for operational announcements including construction alerts, smoke testing notices, sewer outage notifications, and FOG/I&I educational reminders.

City Hall Facebook Page Supplements Public Works communications with broader city announcements including Board meeting notices and major infrastructure project updates.

Press Releases Issued for major infrastructure projects, regulatory milestones, and significant public notices including SSMP updates and smoke testing programs.

11.2 Public Input and Feedback
CLMSD communicates with the public on the development, implementation, and performance of the SSMP through its existing public-facing platforms, including the City website, the Public Works and City Hall Facebook pages, and press releases issued for major infrastructure projects and regulatory milestones. 49 / 352
SSMP updates are presented to the Board of Directors as action items on publicly noticed meeting agendas, consistent with California open meeting requirements. This process provides the formal opportunity for public input on SSMP content as it is developed and adopted.

The SSMP is posted on the City website following each adoption and is available for public inspection at the Utilities Department during normal business hours.

11.3 Satellite and Tributary System Communication
CLMSD maintains a mutual aid agreement with the Lake County Sanitation District (LACOSAN) as described in Element III. Under this agreement, inter-agency flow exchange occurs in both the northern and southern portions of the service area.

CLMSD communicates with LACOSAN on an as-needed basis regarding emergency operations, planned maintenance activities that may affect flows at shared connection points, and capital improvement projects with potential inter-agency impacts. A copy of the mutual aid agreement is included in Appendix 3.D.

11.4 Annual Outreach Calendar — In Development
A formal annual outreach calendar is being developed to ensure consistent public communication on sewer program topics throughout the year. The calendar will include scheduled outreach on: FOG best practices (distributed with utility bills); I&I awareness (timed to wet season preparation); smoke testing advance notice; SSMP update and public comment periods; and SSO response notification protocols for the public. Target completion: Q3 2026. 50 / 352

Utilities Division
Policy No.: U-4 FOG Program Variances Page 2 of 4
BACKGROUND:

Lakeport Municipal Code (LMC) Section 13.20.610 requires all food service establishments (“FSEs”) within the City of Lakeport Municipal Sewer District to take measures to prevent the discharge of materials that can inhibit the function of, or cause damage to, the sanitary sewer system. Such measures include the installation and maintenance of a grease interceptor to prevent the discharge of fats, oil and grease into the sanitary sewer system. These requirements are components of the City’s FOG Program.

FSE owners or authorized representatives (“Users”) may submit a Variance for Cause request to the City if they feel their situation warrants exception to the requirements. Full details regarding the FOG variance process (applications, review, approval/denial, revocation, appeals, etc.) are set forth in LMC Section 13.20.650.

This policy is written to accomplish the following:

1. Establish guidelines for the review and judgment of a Variance for Cause to vary from the requirements LMC Section 13.20.610; and

2. Establish guidelines for the review and judgment of a Variance for Cause request for grease interceptor installation as set forth in LMC Section 13.20.650

3. Establish procedures which the Department and the public should follow when requesting a variance.

POLICY:

1. The Utilities Superintendent (“Superintendent”), or his/her designee, shall make judgment on any Variance Study, resulting from a Variance for Cause request by an entity subject to the Fog Program.

2. The Superintendent may approve or deny a Variance for Cause request at his/her discretion.

3. The Superintendent or designee shall be available by appointment to speak with any affected User about issues related to the FOG Program.

4. From date of approval of a Variance for Cause request, and receipt of the $500.00 Variance Study fee, the City shall make every reasonable effort to complete a Variance Study and make a judgment on the necessity or feasibility of complying with any part of LMC Section 13.20.610 within ninety (90) days.

5. A Variance Study may be terminated at any time if it is determined that continuation of the Study adversely affects the sanitary sewer collection system or treatment works (LMC Section 13.20.650 A. 2.).

6. Per District Resolution No. 2316 (2008), the $500.00 Variance Study fee is non-refundable.

7. Unless sufficient evidence can be found that the FOG Program requirements create an unreasonable hardship, the Superintendent may deny a Variance for Cause request at his discretion.

8. The Superintendent or designee is responsible to commission and complete variance studies.

9. The Superintendent or designee may approve any variance at his/her discretion based on the results of the Variance Study.

Policy No.: U-4 FOG Program Variances Page 3 of 4

10. Users requesting a variance from the FOG Program must submit a Variance for Cause Request Form within six (6) months of receipt of notice to install a grease interceptor. If a variance is not granted by the Superintendent or his/her designee, the FSE shall have six (6) months from the date of the variance denial notice to comply with the FOG requirements.

11. Users may petition the Superintendent, or his/her designee, to reconsider a decision by the Compliance Officer to deny a variance, if submitted in writing within thirty (30) days of the notice of variance denial.

12. The Superintendent, or his designee, may deny a petition to reconsider a variance decision by not acting on the petition (LMC Section 13.20.650 D. 4.).

13. Granted variances are effective in perpetuity from the date granted by the Superintendent or his/her designee.

14. Any granted variance may be revoked by the Utilities Superintendent at the recommendation of the Compliance Officer, based on one or more of the criteria detailed in LMC Section 13.20.650 C.

PROCEDURE:

1. Variance for Cause requests must be submitted to the City in writing using the Variance for Cause Request Form, attached hereto as Attachment A. The form shall be made available at the Community Development Department at City Hall.

2. Upon receipt of a Variance for Cause Request Form, it shall be date-stamped immediately, entered into the appropriate tracking software application, and submitted to the Utilities Superintendent for review. The Superintendent, or designee, shall have thirty (30) days from receipt of the Form to approve or deny the request.

PROCEED TO NEXT PAGE FOR SPILL VOLUME CALCULAION WORKSHEET

SPILL VOLUME CALCULATION
The purpose of this worksheet is to capture the data and method(s} used in estimating the volume of an SSO. Since there are many variables and often unknown values involved, this calculation is just an estimate. Additionally, it is useful to use more than one method, if possible, to validate your estimate. This information is an important part of the City's SSO reporting requirements.

Check all methods and tools that you used:

D Visual estimate
D Measured surface area and volume
0 Duration and flow rate
Vjsual Estjmate Method- Imagine a bucket(s) or barrel(s) of water tipped over.

Size of bucket(s) or Howmanyofthls Multiplier

Estimated
Measured Volume Method (this may take several calculations as may have to break down the odd shaped spill to rectangles, circles, and polygons}
If the entire spill is settled in one area, calculate the volume of spill in feet (L' X W' X D') and convert to gallons (X 7.5 for gallons in a square area, and X .785 for gallons in a circular area}. It is important when guessing depth to measure, if possible, in several locations and use an average depth.

1. Draw a sketch of the spill on separate page

2. Draw shapes and dimensions used for calculations

3. Use correct formula for various shapes (see table below) SSOShape Volume Calculation formula Volume Result

PERSONNEL TRAINING PROGRAM
New City employees are required to participate in an extensive introduction to City policies and procedures, which include hazardous communications and awareness. Elements of this introduction are reviewed regularly and modified as appropriate. A new employee training binder was created in 2020 and includes all City safety policies and other related training materials. The training binder is provided to new employees as part of their initial orientation.

The Public Works and Utilities Divisions conduct bi-weekly safety/staff meetings and routinely discusses safe handling of hazardous materials with employees.

Employees are trained and certified every two years on refresher CPR & First Aid protocols by certified trainers. The most recent CPR/First Aid training was in February 2026. Lakeport Fire Protection District and private vendors have provided hands-on instruction on the use of fire extinguishers to City staff.

City utilities staff undergo regular training on the use of emergency response equipment and supplies that are under City control, including spill simulations and hazardous material release exercises. These training sessions are documented, noting employees who were in attendance and the subject of discussion. Additionally, the City will work actively to include documentation of training received in employee personnel files.

All personnel stationed at the locations described in this plan shall be trained on the following procedures:
☐ Internal alarm/notification
☐ Evacuation/ re-entry procedures & assembly point locations ☐ Emergency incident reporting
☐ External emergency response organization notification ☐ Location(s) and contents of Emergency Response/Contingency Plan ☐ Facility evacuation (drills are to be conducted annually) Personnel responsible for the handling and use of the hazardous materials described in this plan shall be trained regularly on the following:
☐ Safe methods for handling and storage of hazardous materials ☐ Location(s) and proper use of fire and spill control equipment ☐ Spill procedures/emergency procedures
☐ Proper use of personal protective equipment (PPE)
☐ Specific hazard(s) of each chemical to which they may be exposed, including routes of exposure (i.e., inhalation, ingestion, absorption)
☐ Hazardous Waste Handlers/Managers should be trained in all aspects of hazardous waste management specific to their job duties (e.g., container accumulation time requirements, labeling requirements, storage area inspection requirements, manifesting requirements, etc.) 104 / 352

Background
Sanitary sewers serving the City of Lakeport can occasionally overflow due to breaks or blockages in the sewer lines. These overflows can result in discharges of raw sewage into surface water/storm drains and eventually into Clear Lake.

The City’s sewer system also includes eight lift (pump) stations that are needed to convey the flows to the Wastewater Treatment Plant on Linda Lane in the southwest portion of the City.

In order to protect public health and the environment from raw sewage, a quick, coordinated response is needed to stop the source of any overflow and to eliminate the migration of sewage either downstream or into Clear Lake.

The City is required to comply with numerous regulations related to sewage overflows and spills established by the California State Water Resources Control Board. To provide a consistent, statewide regulatory approach to address sanitary sewer spills, the State Water Board adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. 2022-0103-DWQ (Sanitary Sewer Systems General Order) on December 6, 2022. The Sanitary Sewer Systems General Order requires public agencies that own or operate sanitary sewer systems to develop and implement sewer system management plans and report all sanitary sewer spills to the State Water Board’s online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database.

In 2023 the City adopted a new Sewer Spill Emergency Response Plan (SERP) that outlines the City’s SSO response activities, with the objective of minimizing impact of SSOs to the public and the environment.

In achieving this goal, the SERP and its related Sanitary Sewer Spill/Backup Response Workbook serves as a guideline for City of Lakeport personnel in cleaning and mitigating the effects of sanitary sewer spills, as well as in following proper water sampling and spill reporting procedures. Detailed SSO reporting requirements established by the State’s Sanitary Sewer Systems General Order are included in the SERP.

Overflow Emergency Response Plan
Dispatch Responsibility
When a call is received from the public, dispatch personnel obtain:
x Time and date of call
x Time and date when overflow was first noticed
x Specific location of possible overflow
x Description of problem
x Spill details: Has the spill reached a storm drain or Clear Lake? x Caller’s name and call back number or email contact info for follow up 110 / 352
Rev. 12/19/2023
First Responder Assessment of Overflow
When? Assessment Steps
Immediately Assess failure of equipment or overflow release If needed Call for assistance

Finalize the incident documentation using Sewer Spill Field Report forms in the SERP’s Sanitary Sewer Spill/Backup Response Workbook.

Review overall response with Responding Parties.

Traffic and Pedestrian Control
Traffic and Pedestrian Control Recommendations
• Set up cones and warning signs
• Set up warning signs to inform public of hazards if deemed necessary • Close affected entrances and exits from facilities
• Perform lane closures as necessary
• Use caution tape and barricades to prevent public access • Inform Lakeport Police Department of any roadway closures / traffic control SSO Spill Volume and Estimation Methods
Outlined below are three methods that are most often employed for estimating the volume of sanitary sewer spill. City staff preparing the estimate should utilize the most appropriate method for the sewer overflow in question and use the best information available. Refer to the City’s SERP for more details.

Method 1: Eyeball Method
The volume of small spills can be estimated using an “eyeball estimate.” To use this method, imagine the amount of water that would spill from a container listed on the table below. A jug contains 1 gallon, a bucket contains 5 gallons, and a drum contains 55 gallons. If the spill is larger than 55 gallons, try to break the standing water into 55 gal drums and then multiply by 55 gallons. This method is useful for contained spills up to approximately 220 gallons. The photo illustrations incorporated herein should also be referred to when using the Eyeball Method.

https://www.hayward-ca.gov/file/ssmp-sso-emergency-response-sopspdf Method 2: Measured Volume
The volume of most small spills that have been contained can be estimated using this method.

The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume.

Rev. 12/19/2023
Steps for Volume Calculation
Step 1 Sketch the shape of the contained sewage (see figure above).

Step 2 Measure or pace off the dimensions.

Step 3 Measure the depth at several locations and select an average.

Step 4 Convert the dimensions, including depth, to feet.

Step 5 Calculate the area in square feet using the following formulas:

Rectangle: Area = length (feet) x width (feet)
Circle: Area = diameter (feet) x diameter (feet) x 0.785 Triangle: Area = base (feet) x height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet.

Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons.

Method 3: Duration and Flowrate
Calculating the volume of larger spills, where it is difficult or impossible to measure the area and depth, requires a different approach. In this method, separate estimates are made of the duration of the spill and the flowrate. The methods of estimating duration and flowrate are:

Duration
The duration is the elapsed time from the time the spill started to the time that the flow was restored.

Start Time: The start time is sometimes difficult to establish. Here are some approaches:

1. Local residents can be used to establish start time. Inquire as to their observations. Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed or drainage channel) can be used to estimate the start time.

2. Changes in flow on a downstream flowmeter can be used to establish the start time. Typically, the daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days. This method will likely only be effective with consistent weather.

3. Conditions at the spill site change over time and can be used to establish the start time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a light-colored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time.

These observations can be used to estimate the start time in the absence of other information.

Taking photographs to document the observations can be helpful if questions arise later in the process. This method is valid for spills that have been occurring for a long time and may be used in conjunction with either of the above methods.

4. It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall. 115 / 352
Rev. 12/19/2023
End Time: The end time is usually much easier to establish. Field crews on-site observe the “blow down” that occurs when the blockage has been removed. The “blow down” can also be observed in downstream flowmeters.

Flow Rate
The flowrate is the average flow that left the sewer system during the time of the spill. There are three common ways to estimate the flowrate:

1. City of Chico Manhole Overflow Flowrate Chart: This chart, included herein, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting basis for the flowrate estimate.

2. Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flowrate during the spill.

3. Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection.

For example: 22 upstream connections * 9 gallons per hour per connection = 198 gallons per hour / 60 minutes per hour
= 3.3 gallons per minute
Duration and Flow Rate Calculation
Once duration and flowrate have been estimated, the volume of the spill is the product of duration (hours or days) and the flowrate (gallons per hour or gallons per day).

For example: Spill start time = 11:00
Spill end time = 14:00
Spill duration = 3 hours

3.3 gallons per minute x 3 hours x 60 minutes per hour
= 594 gallons

Water Quality Monitoring Requirements
The SSO Water Quality Monitoring Program is meant to assess impacts from SSOs to surface waters in which 50,000 gallons or greater are spilled into local surface waters such as Forbes Creek and Clear Lake. x Refer to SSO Water Quality Sampling, Testing and Reporting protocols set forth in Section 9 Water Quality of the City of Lakeport SERP.
x All samples being tested for indicators are to be analyzed in an accredited or certified laboratory.
x When analyzing samples, only use monitoring instruments and devices that have been properly maintained and calibrated.

SSO Reporting Requirements and Procedures
Any prohibited discharge or spill of untreated or partially treated sewage/wastewater (SSO) from a public sewer system must be reported to state and local agencies responsible for oversight, abatement and public health and safety. Specifically, those agencies include:
x California State Water Resources Control Board (SWRCB) x Central Valley Regional Water Quality Control Board (RWQCB) x State Office of Emergency Services (OES)
x Lake County Environmental Health Department (LCEH)
x Lake County Air Quality Management District (LCAQMD)
x SSO Investigation and Documentation Forms are included in the Sewer Spill/Backup Response Workbook adopted in 2023 and located on PW Network: S:\Yard Share\Utilities\WASTEWATER\SSMP\1 SERP Update DKF Task 2023\1 FINAL SERP 7.27.23. Also available on the City’s website.

City of Lakeport Internal SSO Reporting Protocol

1. Any active or inactive SSO which occurs within the City’s sewer system (including the treatment plant) and is a result of, but not limited to, a blockage or obstruction, surge, equipment failure or malfunction, or inappropriate connection of a private lateral to a City main must be reported using the protocols and procedures outlined within this policy and the City’s SERP.

2. For purposes of this Policy, an active SSO shall refer to any spill that is in progress at the time identified or observed by City staff. An inactive SSO is any suspected spill positively determined to have occurred by the Utilities Director, or designee.

3. Evidence of any suspected SSO reported to, or identified by, Department staff should be evaluated by the Utilities Director, or designee. That individual shall determine whether a SSO did occur and, if so, the magnitude of the spill.

4. If evidence at a suspected SSO site suggests that a spill occurred, but an exact source, amount of discharge, and destination cannot reasonably be substantiated, the Utilities Director may report the incident to the Compliance Officer at his/her discretion.

5. Unless creating a nuisance (as determined by the Utilities Director), any active, inactive or suspected SSO on private property (PLSD), resulting from a blockage or failure of a sewer lateral from the property to the City right-of-way may not be reported to the Compliance Officer if the source and destination of the spill is determined to be localized to that property.

6. For purposes of this policy, a nuisance shall be defined as anything which meets all the following criteria:
a. Is a health hazard or has the possibility of being a health hazard, or is indecent or offensive to the senses and restricts the free use of the property;
118 / 352
Rev. 12/19/2023
b. Affects the entire community, neighborhood, or any other reasonable number of persons; and c. Occurs during, or because of, the treatment or disposal of sewage or wastewater.

7. Reporting of active or suspected SSOs on private property, deemed reportable by the Utilities Director, shall include ownership information of that property and contact information for that owner.

8. If any active or suspected SSO (as determined by the Utilities Director to be an inactive spill) is observed or suspected of reaching a drainage channel or surface water, the Compliance Officer must be notified immediately.

9. Any SSO deemed reportable by the Utilities Director must be reported to the Compliance Officer.

SSOs shall be reported as required by the State’s Sanitary Sewer Systems General Order using the reporting forms included in the SERP’s Sewer Spill/Backup Response Workbook.

10. Any active or inactive SSO estimated to be over 1,000 gallons in volume must be reported to the Public Works Director and the City Manager.

11. The Utilities Director, acting as the City’s Legally Responsible Official (LRO), shall be responsible for all SSO regulatory reporting to state and local agencies (referred to herein) and is authorized to certify such reporting as the duly authorized representative of the City of Lakeport Municipal Sewer District. The Compliance Officer is a CIWQS Data Submitter. LROs and Data Submitters have different levels of access in CIWQS:
x Data Submitters are authorized to enter data into CIWQS for the facility or collection system to which they have been given access by an LRO.
x In addition to Data Submitter rights, LROs are authorized to certify and submit reports for the regulated facility or collection system. LROs have the additional ability to manage active Data Submitters under their facility or collection system.

12. Individual SSO records, including SSO Investigation and Report Forms, shall be maintained and kept by the Department for five (5) years. The RWQCB may extend this period at their discretion.

When reporting a SSO to the Compliance Officer or Utilities Director, the following procedures shall be followed:

1. As soon as Department staff become aware of an active or inactive SSO (as determined by the Utilities Director), and without substantially impeding cleanup or other emergency efforts, the Sewer System Supervisor, or designee, shall complete, sign and submit a Sanitary Sewer Spill Field Report form (see Section D-1 of the SERP’s Sewer Spill/Backup Response Workbook) to the Compliance Officer.

2. If an active or inactive SSO results in discharge to a drainage channel or surface water, the Sewer System Supervisor shall immediately notify the Utilities Director by phone.

3. Upon receipt of notification of an active or inactive SSO discharging to a drainage channel or surface water, the Utilities Director shall immediately notify the Compliance Officer who shall complete all required notifications and reporting. A separate Illicit Discharge report may be necessary for certain SSOs that impact Waters of the State. An illicit discharge is defined as any discharge to the City's storm drain system, or to natural surface waters, that is not composed entirely of stormwater. See City of Lakeport Public Works SOP PW01 Illicit Stormwater Discharge Detection, Response & Reporting for more information.

4. Category 4 SSO reporting requirements:
a. If, during any calendar month, Category 4 spills occur, certify monthly, the estimated total spill 119 / 352
Rev. 12/19/2023
volume exiting the sanitary sewer system, and the total number of all Category 4 spills into the online CIWQS Sanitary Sewer System Database, within 30 days after the end of the calendar month in which the spills occurred.
b. Upload and certify a report, in an acceptable digital format, of all Category 4 spills to the online CIWQS Sanitary Sewer System Database, by February 1st after the end of the calendar year in which the spills occur.

5. The Compliance Officer shall complete and submit an Annual Report into the online CIWQS Sanitary Sewer System Database by April 1 of each year. The previous year’s Annual Report shall be updated by April 1 of each year after the Effective Date of the 2022 General Order, for each calendar year (January 1 through December 31). See Section 3.9 of Attachment E1 of State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR)

6. If no SSOs have been reported, identified, or substantiated in any given calendar month, the Compliance Officer shall submit a “No Spill Certification Report” to the SWRCB through the CIWQS Database. This report must be submitted no later than 30 days after the end of the month in question.

7. All reports and information submitted to the SWRCB shall be certified as described in State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) referenced above.

8. The Compliance Officer or Utilities Director shall be responsible for notifying the Public Works Director of any spill over 1,000 gallons in volume; the Public Works Director shall notify the City Manager.

9. The Compliance Officer shall report SSOs to all appropriate state and local agencies based on the following criteria and reporting protocols:

CATEGORIES DEFINITIONS
CATEGORY 1 A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under the State Water Board Order No. WQ 2022- 0103-DWQ (SSSWDR) that results in a discharge to:
x A surface water, including a surface water body that contains no flow or volume of water; or
x 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.

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 shall report all Category 1 spills per section

3.1 of Attachment E1 (Notification, Monitoring, Reporting and Record keeping Requirements) of State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR).

CATEGORY 2 A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under the State Water Board Order No.

WQ 2022-0103-DWQ (SSSWDR) 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. 120 / 352
Rev. 12/19/2023

CATEGORIES DEFINITIONS
CATEGORY 3 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 the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) that does not discharge to a surface water. A spill of equal to or greater than SO 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.

CATEGORY 4 A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under the State Water Board Order No. WQ 2022-0103- DWQ (SSSWDR) 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.

PRIVATE

LATERAL

SEWAGE SPILL
Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately-owned sewer lateral connected to the enrollee’s sanitary sewer system or from other private sewer assets. Spills from private laterals that the enrollee becomes aware of may be voluntarily reported to the SSO Database.

The Lakeport SERP includes the following definitions:
x A private sanitary sewer system is a sanitary sewer system of any size that is owned and/or operated by a private individual, company, corporation, or organization. A private sanitary sewer system may or may not connect into a publicly owned sanitary sewer system.
x Private Sewer Lateral: In Lakeport, upper laterals are typically privately owned and maintained. A private sewer lateral is the privately-owned lateral that transports sewage from private property(ies) into a sanitary sewer system.

The reporting deadline for submittal of a SSO report to the SWRCB depends on the classification of the spill as shown in the above table and in the City’s Spill Emergency Response Plan (SERP) and the Notification, Reporting, Monitoring and Recordkeeping Requirements outlined in Attachments E-1 and E-2 of the State’s Sanitary Sewer Systems General Order.

EMERGENCY RESPONSE PLAN (2023) + SERP SEWER
SPILL/BACKUP RESPONSE WORKBOOK (2023) FOR

MORE REPORTING DETAILS AND ALL SSO REPORTING
FORMS
From the 2023 Sewer Spill Emergency Response Plan:

1. PURPOSE
The purpose of the City of Lakeport Spill Emergency Response Plan (SERP) is to support a prompt, orderly and effective response to spills (sanitary), reduce spill volumes, and collect information for prevention of future spills. A "spill" in this document is defined, by State Water Board Order No. WQ 2022-0103-DWQ as 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.

The SERP provides guidelines for City personnel to follow in responding to, cleaning up, reporting, and properly documenting spills that may occur within the City's service area. This SERP satisfies the State Water Board Order No. WQ 2022-0103- DWQ, which require wastewater collection agencies to have a Spill Emergency Response Plan.

Additionally, the SERP outlines procedures for responding to sanitary sewer spill backups into structures as required by the City's insurer. "Backup" is a term typically used by insurers to describe property damage resulting from exposure and contact to untreated or partially treated sewage.

2. POLICY
The City's employees are required to report all spills from agency owned sewer mains and publicly owned laterals found and to take the appropriate action to secure the spill area, properly report to the appropriate regulatory agencies, relieve the cause of the spill, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City's goal is to respond to sewer system spills as soon as possible following notification. The City will follow reporting procedures regarding sewer spills as set forth by the Central Valley Regional Water Quality Control Board and the State Water Board Order No. WQ 2022- 0103-DWQ (SSSWDR).

The Lakeport SERP and Sewer Spill/Backup Response Workbook are located on the PW network: S:\Yard Share\Utilities\WASTEWATER\SSMP\1 SERP Update DKF Task 2023\1 FINAL SERP 7.27.23 and on the City’s website:

CITY OF LAKEPORT

PUBLIC WORKS DEPARTMENT

STANDARD OPERATING PROCEDURE
Illicit discharges can contribute high levels of pollutants to waterbodies. Pollutants commonly found in illicit discharges include raw sewage (viruses and bacteria), heavy metals, toxics, o il and grease, solvents, and nutrients. Pollutant levels from these illicit discharges can be high enough to significantly degrade water quality and threaten aquatic, w ildlife, and human health.

IDENTIFYING ILLICIT DISCHARGES AND CONNNECTIONS:

See attached memorandum that provides details for identifying Illicit Discharges and Illicit Connections to the City's MS4.

LAKEPORT STAFF PROCEDURE:

1. Upon verification of an llllclt Discharge, either during a routine MS4 1nspecr1011 or the result of t he investigation of a complaint or report of a potential discharge, immedia tely report the violation to your supervisor who will evaluate the situation and initiate cleanup procedures if deemed necessary.

2. Take photos of Illicit Discharge and impacted areas prior to initiating clean-up activities.

3. Refer to the attached CASO/\ Spill Prevention and Control BMP for spill control procedures.

Members of the Public Works Department have received advanced HAZWOPER training including specialized water-based HazMat Spill Response training.

4. If deemed necessary, City staff shall use spil l mitigation materials stored in the City's Spill Response Trailer to control the Illicit Discharge. All mitigation materials used in a spill response shall be logged/tracked by City staff and replaced ASAP to m aintain adequate stock in the trailer.

5. Supervisors:
a) Contact Compliance Otficer ASAP who will initiate all required Illicit Discharge reporting tasks.
b) Contact Public Works Director if Compliance Officer is unavailable. c) Refer to the attached Lake County Clean Water Program Illicit Dischar.ge Investigation and Reporti ng Procedures Guide for reporting protocols, including requirement to contact Lake County Environmental Health and the CalOES Warning Center and prepare and submit a written follow up report.

Spill Prevention and Control
Description and Purpose
Prevent or reduce the discharge of pollutants to drainage systems or watercourses from leaks and spills by reducing the chance for spills, stopping the source of spills, containing and cleaning up spills, properly disposing of spill materials, and training employees.

This best management practice covers only spill prevention and control. However, WM-1, Materials Delivery and Storage, and WM-2, Material Use, also contain useful information, particularly on spill prevention. For information on wastes, see the waste management BMPs in this section.

Suitable Applications
This BMP is suitable for all construction projects. Spill control procedures are implemented anytime chemicals or hazardous substances are stored on the construction site, including the following materials:
■ Soil stabilizers/binders
■ Dust palliatives
■ Herbicides
■ Growth inhibitors
■ Fertilizers
■ Deicing/anti-icing chemicals

■ Fuels
■ Lubricants
■ Other petroleum distillates
Limitations
■ In some cases it may be necessary to use a private spill cleanup company. ■ This BMP applies to spills caused by the contractor and subcontractors. ■ Procedures and practices presented in this BMP are general. Contractor should identify appropriate practices for the specific materials used or stored onsite Implementation
The following steps will help reduce the storm water impacts of leaks and spills:

Education
■ Be aware that different materials pollute in different amounts. Make sure that each employee knows what a "significant spill" is for each material they use, and what is the appropriate response for "significant• and "insignificant• spills. ■ Educate employees and subcontractors on potential dangers to humans and the environment from spills and leaks.
■ Hold regular meetings to discuss and reinforce appropriate rusposal procedures (incorporate into regular safety meetings).
■ Establish a continuing education program to indoctrinate new employees. ■ Have contractor's superintendent or representative oversee and enforce proper spill prevention and control measures.

General Measures
■ To the extent that the work can be accomplished safely, spills of oil, petroleum products, substances listed under 40 CFR p.arts 110,117 , and 302, and sanitary and septic wastes should be contained and cleaned up immediately.
■ Store hazardous materials and wa,stes in covered containers and protect from vandalism. ■ Place a stock-pile of spill cleanup materials where it will be readily accessible. ■ Train employees in spill prevention and cleanup.
■ Designate responsible individuals. to oversee and enforce control measures. ■ Spills should be covered and protected from stormwater runon during rainfall to the extent that it doesn't compromise clean lllp activities.
■ Do not bury or wash spills "~th water.

Spill Prevention and Control WM-4
■ Store and dispose of used clean up materials, contaminated materials, and recovered spill material that is no longer suitable for the intended purpose in conformance with the provisions in applicable BMPs.
■ Do not allow water used for cleaning and decontamination to enter stornn drains or watercourses. Collect and dispose of contaminated water in accordance "~th WM-10, Liquid Waste Management.
■ Contain water overflow or minor water spillage and do not allow it to discharge into drainage facilities or watercourses.
■ Place proper storage, cleanup, and spill reporting instructions for hazardous materials :stored or used on the project site in an open, conspicuous, and accessible location. ■ Keep waste storage areas clean, well organized, and equipped with ample cleanup supplies as appropriate for the materials being stored. Perimeter controls, containment structures, ,covers, and liners should be repaired or replaced as needed to maintain proper function.

Cleanup
■ Clean up leaks and spills immediately.
■ Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and absorbent material for larger spills. If the spilled material is hazardous, then the used cleanup materials are also hazardous and must be sent to either a certified laundxy (rags) or disposed of as hazardous waste.
■ Never hose down or bury dry material spills. Clean up as much of the material as possible and dispose of properly. See the waste management BMPs in this section for specific information.
llfittor Spills
■ Minor spills typically involve small quantities of oil, gasoline, paint, etc. which can be ,controlled by the first responder at the discovery of the spill. ■ Use absorbent materials on small spills rather than hosing down or burying the spill. ■ Absorbent materials should be promptly removed and disposed of prope rly. ■ Follow the practice below for a minor spill:
- Contain the spread of the spill.
- Recover spilled materials.
- Clean the contaminated area and properly dispose of contaminated materials.

Semi-Significant Spills
■ Semi-significant spills still can be co:ntrolled by the first responder along: with the aid of other personnel such as laborers and the foreman, etc. This response may require the ,cessation of all other activities.

Spill Prevention and Control WM-4
■ Spills should be cleaned up immediately:

Contain spread of the spill.

Notify the projed foreman immediately.

If the spill occurs on paved or impermeable surfaces, clean up using "dry" methods (absorbent materials, cat litter and/or rags). Contain the spill by encircling with absorbent materials and do not let the spill spread widely.

If the spill occurs in dirt areas, immeruately contain the spill by constructing an earthen ruke. Dig up and pr,operly dispose of contaminated soil.

If the spill occurs during rain, cover spill with tarps or other material to prevent contaminating runoff.

Sig11ijica11tfHazardous Spills
■ For significant or hazardous spills that cannot be controlled by personnel in the immediate vicinity, the following steps should be taken:

Notify the local emergency response by waling 911. In adrution to 911, the contractor will notify the proper county officials. It is the contractor's responsibility to have all emergency phone numbers at the construction site.

Notify the Governor's Office of Emergency Services Warning Center, (916) 845-8911.

For spills of federal reportable quantities, in conformance with the requirements in 40 CFR parts 110,119, and 302, the contractor should notify the National Response Center at (800) 424-8802.

Notification should first be made by telephone and followed up ,-~th a written report.

The services of a spills contractor or a Haz-Mat team should be obtained immediately.

Construction personnel should not attempt to clean up until the appropriate and qualified staffs have arrived at the job site.

Other agencies which may need to be consulted include, but are not limited to, the Fire Department, the Public Works Department, the Coast Guard, the Highway Patrol, the City/ County Police Department, Department of Toxic Substances, California Division of Oil and Gas, Cal/OSHA, etc.

Reporting
■ Report significant spills to local agencies, such as the Fire Department; they can assist in cleanup.
■ Federal regulations require that any significant oil spill into a water body or onto an adjoining shoreline be reported to the National Response Center (NRC) at 800-424-8802 (24 hours).

Use the follo,-~ng measures related to specific activities:

Vehicle and Equipment Maintenance
• If maintenance must oecur onsite, use a designated area and a secondary containment, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills.
■ Regularly inspect onsie vehicles and equipment for leaks and repair immeruately ■ Check incoming vehicles and equipment (inclurung delivery trucks, and employee and subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or equipment onsite.
■ Always use secondary containment, such as a drain pan or drop cloth, to catch spills or leaks when removing or changing fluids.
■ Place drip ?ans or absorbent materials under paving equipment when not in use. ■ Use absorbent materials on small spills rather than hosing down or barying the spill. Remove the absorbent materials promptly and ruspose of properly. ■ Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full drip pans or other open containers lying around
■ Oil filters disposed of in trashcans or dumpsters can leak oil and pollute stormwater. Place the oil filter in a funnel over a waste oil-recycling drum to drain excess oil before rusposal.

Oil filters can also be recycled. Ask the oil supplier or recycler about recycling oil filters. ■ Store cracked batteries in a non-leaking secondary container. Do this with all cracked batteries even if you think all the acid has drained out. If you drop a battery, treat it as if it is r.r.::ir:kP.ci. Pnt 1t 1nto thP. r:ont.::iinmP..nt .1rP;:i until yon .1rP. !.nrP. it 1~ not l~.1klne.

Vehicle a nd Equipment Fueling
■ If fueling must occur onsite, use designate areas, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills. ■ Discourage "topping off' of fuel tanks.
■ Always use secondary containment, such as a drain pan, when fueling to catch spills/ leaks.

Costs
Prevention of leaks and spills is inexpensive. Treatment and/ or rusposal of contaminated soil or water can b~ quite e1.11ensive.

I nspection and Maintenance
■ Inspect and verify that activity- based BMPs are in place prior to the commencement of associated activities. While activities associated "~th the BMP are under way, inspect weekly during the rainy season and of two-week intervals in the non-rainy season to verify continued BMP implementation.
■ Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur.

RE: Identifying Illicit Stormwater Discharges and Illicit Connections to City's MS4 Identifying Illicit Discharges
Lakeport's stormwater conveyance system {"MS4") includes traditional storm drain inlets, pipes and culverts along with other connected conveyances such as ditches, open channels and seasonal creeks or drainages. In Lakeport, all MS4 outfalls drain into Clear Lake.

For a variety of reasons liquids other than stormwater commonly enter the City's MS4.

Sometimes there is a misconception that t he water or other substance that enters the stormwater conveyance system will be treated and cleaned before it reaches our local waterbodies. However, this is not true. Anything that enters our MS4 will go directly to nearest waterbody and ultimately into Clear Lake which may cause serious environmental damage.

State regulations and the a ty's Municipal Code prohibits Illicit Discharges into the aty's stormwater system. Please see t he questions and answers below to learn more about illicit discharges and how to identify an illicit discharge.

What is an "illicit discharge" to a stormwater conveyance system?
An illicit discharge is any discharge to a stormwater conveyance system, drainage ditch, seasonal stream or other waterbody that is not composed entirely of stormwater. An illicit discharge could be the result of someone dumping a pollutant (automobile fluids, paint etc.) into the MS4; the result of an illicit connection into the cor.veyance system, such as a sewer pipe connected to a stormwater pipe; or a pipe that bypasses the sewer connection, producing a direct discharge into open channels or streams.

What is an "illicit connection" to a stormwater conveyance system?
An illicit connection is an improper physical connection of illicit discharges to the stormwater conveyance system. Examples include: a sewer pipe that is connected to the stormwater conveyance system t hat produces a continuous discharge of raw sewage to the conveyance 1 1 Page
150 / 352
xxvi Rev. 1/23/2024
system or a shop floor drain connected to the stormwater conveyance system producing a discharge of wash water or other pollution into the City's MS4.

What are the hazards associated with illicit discharges? Illicit discharges can contribute high levels of pollutants to waterbodies. Pollutants commonly found in illicit discharges include raw sewage (viruses and bacteria), heavy metals, toxics, oil and grease, solvents and nutrients. Pollutant levels from these illicit discharges have been shown in EPA studies to be high enough to significantly degrade water quality and threaten aquatic, wildlife and human health.

So how can you tell a normal stormwater discharge from an illicit discharge?
Dry weather flow is the best indication that the water coming from an outfall pipe is from an illicit connection. If it has not rained in at least three days and there is water coming from a stormwater outfall pipe, chances are that water is from an illegal source.

Although it is a gocd indication, dry weather flow is not always from an illicit source. Sometimes groundwater seeps into the stormwater conveyance system and is discharged through the outfall pipe. This isa natural source and is not illicit .

When should I report dry weather flow?
The best way to tell if the dry weather flow is an illicit discharge, and should be reported, is by examining the characteristics of the water being discharged.

1. Does the discharge have a distinct odor?
Some smells coming from an outfall pipe are an immediate indicator of an illicit discharge - for example~ a sewage~ gasoline, or chemical smell should be reported.

2. Is the water cloudy or full of sediment?
Gray wat er that should be treated at a sewage treatment plant may cause a cloudy appearance in the discharged water. A construction sit e wit hout proper stormwater best management practices could be discharging sediment to a storm drain. These conditions should be reported.

3. Is there anything floating in the discharge?
Soap suds and oil sheens are examples of floatables that may be found in an illicit di scharge.

These conditions should be reported.

4. What color is the discharge?
An abnorma ly colored discharge is a good indicat ion that there is an illicit coonection to t he MS4. However sometimes an abnormal color may have a nat ural cause. For ilst ance~ an orange discharge could be nat urally occurring from groundwater that is high in iron. However, if an abnormal color is coupled with another one of the characteristics listed here (odor~ floatables~ cloudiness, vegetative growth), tt should be reported.

5. Is there excessive vegetation around the outfall pipe? Exce.ssive vegetat ion around the outfall pipe as oppo sed to t he surrounding area is an indication of increased nutrients in the stormwater discharge. This could be from fertilizers or sewage in t he discharge and should be reported.

1. PURPOSE
The purpose of the City of Lakeport Spill Emergency Response Plan (SERP) is to support a prompt, orderly and effective response to spills (sanitary), reduce spill volumes, and collect information for prevention of future spills. A “spill” in this document is defined, by State Water Board Order No. WQ 2022-0103-DWQ as 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.

The SERP provides guidelines for City personnel to follow in responding to, cleaning up, reporting, and properly documenting spills that may occur within the City’s service area. This SERP satisfies the State Water Board Order No. WQ 2022-0103-DWQ, which require wastewater collection agencies to have a Spill Emergency Response Plan.

Additionally, the SERP outlines procedures for responding to sanitary sewer spill backups into structures as required by the City’s insurer. “Backup” is a term typically used by insurers to describe property damage resulting from exposure and contact to untreated or partially treated sewage.

2. POLICY
The City’s employees are required to report all spills from agency owned sewer mains and publicly owned laterals found and to take the appropriate action to secure the spill area, properly report to the appropriate regulatory agencies, relieve the cause of the spill, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City’s goal is to respond to sewer system spills as soon as possible following notification. The City will follow reporting procedures regarding sewer spills as set forth by the Central Valley Regional Water Quality Control Board and the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR).

3. DEFINITIONS AS USED IN THIS SERP
ANNUAL REPORT: An Annual Report (previously termed as Collection System Questionnaire in previous State Water Board Order No. 2006-0003-DWQ) is a mandatory report in which the City provides a calendar-year update of its efforts to prevent spills.

BASIN PLAN: A Basin Plan is a water quality control plan specific to a Regional Water Quality Control Board (Regional Water Board), that serves as regulations to: (1) define and designate beneficial uses of surface and groundwaters, (2) establish water quality objectives for protection of beneficial uses, and (3) provide implementation measures.

BENEFICIAL USES: The term “Beneficial Uses” is a Water Code term, defined as the uses of the waters of the State that may be protected against water quality degradation. Examples of beneficial uses include but are not limited to, municipal, domestic, agricultural, and industrial supply; power generation; recreation; aesthetic enjoyment; navigation; and preservation and enhancement of fish, wildlife, and other aquatic resources or preserves.

CALIFORNIA INTEGRATED WATER QUALITY SYSTEM (CIWQS): CIWQS is the statewide database that provides for mandatory electronic reporting as required in State and Regional Water Board-issued waste discharge requirements.

DATA SUBMITTER: A Data Submitter is an individual designated and authorized by the City’s Legally Responsible Official to enter spill data into the online CIWQS Sanitary Sewer System Database. A Data Submitter does not have the authority of a Legally Responsible Official to certify reporting entered into the online CIWQS Sanitary Sewer System Database. 156 / 352

Page 5 of 43 DRAINAGECONVEYANCE SYSTEM: A drainage conveyance system is a publicly- or privately-owned separate storm sewer system, including but not limited to drainage canals, channels, pipelines, pump stations, detention basins, infiltration basins/facilities, or other facilities constructed to transport stormwater and non-stormwater flows.

ENVIRONMENTALLY SENSITIVE AREA: An environmentally sensitive area is a designated agricultural and/or wildlife area identified to need special natural landscape protection due to its wildlife or historical value.

EXFILTRATION: Exfiltration is the underground exiting of sewage from a sanitary sewer system through cracks, offset or separated joints, or failed infrastructure due to corrosion or other factors.

FOG – Fats, Oils, and Grease: Refers to fats, oils, and grease typically associated with food preparation and cooking activities that can cause blockages in the sanitary sewer system.

HYDROLOGICALLY CONNECTED: Two waterbodies are hydrologically connected when one waterbody flows, or hasthe potential to flow, into the other waterbody. For the purpose of the SWRCB Order, groundwater is hydrologically connected to a surface water when the groundwater feeds into the surface water. See image, right. The surface waterbody in this example is termed a gaining stream as it gains flow from surrounding groundwater.

LATERAL (INCLUDING LOWER AND UPPER LATERAL): A lateral is an underground segment of smaller diameter pipe that transports sewage from a customer’s building or property (residential, commercial, or industrial) to the City’s main sewer line in a street or easement. Upper and lower lateral boundary definitions are subject to local jurisdictional codes and ordinances, or private system ownership. The City is typically responsible for lower lateral maintenance. A lower lateral is the portion of the lateral located between the sanitary sewer system main, and either the property line, sewer clean out, curb line, established utility easement boundary, or other jurisdictional locations. An upper lateral isthe portion of the lateral from the property line, sewer clean out, curb line, established utility easement boundary, or other jurisdictional locations, to the building or property.

LEGALLY RESPONSIBLE OFFICIAL: A Legally Responsible Official is an official representative, designated by the City, with authority to sign and certify submitted information and documents required by State Water Board Order No. WQ 2022- 0103-DWQ (SSSWDR).

MAINLINE SEWER: Refers to City wastewater collection system piping downstream of the sewer laterals that is not a private sewer lateral connection to a building.

MAINTENANCE HOLE OR MANHOLE: Refers to an engineered structure that is intended to provide access to a sanitary sewer for maintenance and inspection
NOTIFICATION OF A SPILL: Refers to the time at which the City becomes aware of a spill event through observation or notification by the public or other source.

NUISANCE: For the purpose of the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), a nuisance, as defined in Water Code section 13050(m), is anything that meets all of the following requirements:
• Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property; Gaining Stream

• Upstream Connections Method
In addition, the following will be documented on the Sewer Spill Report form:

1. Description, photographs, and GPS coordinates of the system location where the spill originated. If a single spill event results in multiple appearance points, provide GPS coordinates for the appearance point closest to the failure point and describe each additional appearance point in the spill appearance point explanation field;

2. Estimated total spill volume exiting the system;

3. Description and photographs of the extent of the spill and spill boundaries;

4. Did the spill reach a drainage conveyance system? If yes:
• Description of the drainage conveyance system transporting the spill; • Photographs of the drainage conveyance system entry location(s); • Estimated spill volume that reached the drainage conveyance system; • Estimated spill volume fully recovered from the drainage conveyance system; • Estimated spill volume remaining within the drainage conveyance system • Estimated spill volume discharged to a groundwater infiltration basin or facility, if applicable; • Estimated spill travel time from the point of entry into the drainage conveyance system to the point of discharge into the receiving water.

5. Estimated total spill volume recovered.

8.2 RECOVERY OF SPILLED SEWAGE
Vacuum up and/or pump the spilled sewage and wash down water and discharge it back into the sanitary sewer system. Thoroughly recover and dispose of sewage and wash down water.

8.3 CLEAN-UP AND DISINFECTION
Clean up procedures will be implemented to reduce the potential for human health issues and adverse environmental impacts associated with a spill event. The procedures described are for dry weather conditions and will be modified as required for wet weather conditions. Where cleanup is beyond the capabilities of City staff, a cleanup contractor will be used.

Private Property
City crews are responsible for the cleanup when the property damage is minor in nature and is outside of private building dwellings, such as in front, side and backyards, easements, etc. In all other cases, affected property owners can call a water damage restoration contractor to complete the cleanup and restoration. If the overflow into property is the definite cause of City system failure, the property owner can call out a water damage restoration contractor to complete the cleanup and restoration. In both cases, property owners may submit a claim form.

Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water and/or deozyme or similar nontoxic biodegradable surface disinfectant until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Take steps to contain and vacuum up the wastewater. Allow area to dry. Repeat the process if additional cleaning is required.

Landscaped and Unimproved Natural Vegetation
Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Either contain or vacuum up the wash water so that none is released. Allow the area to dry. Repeat the process if additional cleaning is required.

Natural Waterways
The Department of Fish and Wildlife will be notified by CalOES for spills greater than or equal to 1,000 gallons. For spills less than 1,000 gallons, contact Lake County Environmental Health for direction.

Wet Weather Modifications
Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Omit flushing and sampling during heavy storm events (i.e., sheet of rainwater across paved surfaces) with heavy runoff where flushing is not required and sampling would not provide meaningful results.

8.4 PUBLIC NOTIFICATION
Signs will be posted and barricades put in place to keep vehicles and pedestrians away from contact with spilled sewage. Lake County Environmental Health instructions and directions regarding placement and language of public warnings will be followed. Additionally, the Utilities Director or designee will use their best judgment regarding supplemental sign placement in order to protect the public and local environment. Signs will not be removed until directed by Lake County Environmental Health or the Utilities Director or designee.

Creeks, streams and beaches that have been contaminated as a result of a spill will be posted at visible access locations until the risk of contamination has subsided to acceptable background bacteria levels. Document the number and location of posted signs. The area and warning signs, once posted, will be checked every day to ensure that they are still in place. Photographs of sign placement will be taken.

In the event that an overflow occurs at night, the location will be inspected first thing the following day. The field crew will look for any signs of sewage solids and sewage-related material that may warrant additional cleanup activities.

When contact with the local media is deemed necessary, the Utilities Director or their designee will provide the media with all relevant information.

9.1 SURFACE WATERS OF CONCERN
The following waters of the State are in the City’s service area:
• Clear Lake
• Forbes Creek

9.2 WATER QUALITY SAMPLING AND TESTING
For sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water, the City or designee will conduct the following water quality sampling as soon as possible but no later than 18 hours after the City’s knowledge of a potential discharge to a surface water. Collect one water sample, each day of the duration of the spill, at:
• The DCS-001 location as described in section 9.5 (Receiving Water Sampling Locations) below, if sewage discharges to a surface water via a drainage conveyance system; and/or • Each of the three receiving water sampling locations in section 9.5 (Receiving Water Sampling Locations) below;
If the receiving water has no flow during the duration of the spill, the City must report “No Sampling Due To No Flow” for its receiving water sampling locations.

The lab staff will collect water quality samples in accordance with State Water Board Order No. WQ 2022-0103- DWQ (SSSWDR).

The lab staff collecting the samples will complete the Chain of Custody prior to transferring ownership of the samples to the Clear Lake Environmental Research Center (CLERC) Lab.

The Clear Lake Environmental Research Center (CLERC) Lab shall analyze the collected receiving water samples for the following constituents:
• Ammonia, and
• E. coli:
o Amendment to the Basin Plan for Bacteria
Updates the water quality objectives for bacteria to use an E. coli pathogen indicator rather than fecal coliform. Status: Adopted by the Regional Board on 6 September 2002 in Resolution No.

R5-2002-0150. This Amendment was not submitted for approvals due to a similar, concurrent state-wide effort. Updated state-wide bacteria water quality objectives are included in the State Water Resources Control Board's Part 3 of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries of California, Bacteria Provisions and a Water Quality Standards Variance Policy (https://www.waterboards.ca.gov/bacterialobjectives/docs/bacteria.pdf), effective 4 February 2019

City of Lakeport
Spill Emergency Response Plan 7-27-23
© 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 19 of 43 Sufficiently Sensitive Methods
Sample analysis must be conducted according to sufficiently sensitive test methods approved under 40 Code of Federal Regulations Part 136 for the sample analysis of pollutants. For the purposes of State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), a method is sufficiently sensitive when the minimum level of the analytical method approved under 40 Code of Federal Regulations Part 136 is at or below the receiving water pollutant criteria.

Environmental Laboratory Accreditation Program-Accredited Laboratories The analysis of water quality samples required per State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) must be performed by a laboratory that has accreditation pursuant to Article 3 (commencing with section 100825) of Chapter 4 of Part 1 of Division 101 of the Health and Safety Code. (Water Code section 13176(a).) The State Water Board accredits laboratories through its Environmental Laboratory Accreditation Program (ELAP).

9.5 RECEIVING WATER SAMPLING LOCATIONS
Receiving water samples shall be collected at the following locations.

Sampling of Flow in Drainage Conveyance System (DCS) Prior to Discharge Sampling Location Sampling Location Description
DCS-001 A point in a drainage conveyance system before the drainage conveyance system flow discharges into a receiving water.

Receiving Surface Water Sampling (RSW)1
Sampling Location Sampling Location Description
RSW-001:

Point of Discharge
A point in the receiving water where sewage initially enters the receiving water.

RSW-001U:

Upstreamof Point of
Discharge
A point in the receiving water, upstream of the point of sewage discharge, to capture ambient conditions absent of sewage discharge impacts.

RSW-001D:

Downstream of
Point ofDischarge
A point in the receiving water, downstream of the point of sewage discharge, where the spill material is fully mixed with the receiving water.

9.6 STREAM VELOCITY MEASUREMENTS
If sampling is performed after the spill has stopped, the velocity of the impacted surface water must be determined to estimate spill travel time and select an accurate Downstream sample location. One way to measure the spill travel time is to use a velocity probe (such as a Global Water FP111-S Flow Probe) to determine the rate of 1 The City must use its best professional judgment to determine the upstream and downstream distances based on receiving water flow, accessibility to upstream/downstream waterbody banks, and size of visible sewage plume. 171 / 352

9.7 SAMPLE TYPES
Grab Samples
Grab samples are appropriate for the characterization of surface waters at a particular time and place, to provide information about minimum and maximum concentrations, and to allow for the collection of variable sample volume.

Grab samples may be collected directly into the sample container, or a clean decontaminated intermediate container may be used if a wading sample is not possible or safe. If an intermediate container is used, when in the field, double rinse the sampling device (bucket, automatic sampler) with sample water prior to collecting the sample and be sure to discard rinse water downstream of where sample will be collected. If samples are collected in a bucket and distributed into a consolidation collection container, swirl the contents of the bucket as it is being poured into the consolidation collection container to avoid settling of solids (and pour in back-and-forth pattern – e.g., 1-2-3-3-2-1).
• Grab Sample: A grab sample is defined as an individual sample collected at a given time. Grab samples represent only the condition that exists at the time the sample is collected (US EPA 1977). • Surface Grab Sample: A sample collected at the water surface (i.e., skimming) directly into the sample container or into an intermediate container such as a clean bucket. A single or discrete sample collected at a single location.

Field Blanks
Field Blanks are used to evaluate the potential for contamination of a sample by site contaminants from a source not associated with the sample collected (e.g., airborne dust, etc.). Sterile, deionized water is taken into the field in a sealed container. This is the stock water. The stock water is then poured into the sample container. The containers and sample submission forms are labeled as “Field Blank.” The same template selected for the test samples should be used. Field blanks are subject to the same holding time limitations as samples. The appropriate FIELD QC box on the sample Chain of Custody form should be checked.

9.8 SAMPLE LABELING AND CHAIN OF CUSTODY PROCEDURES
At a minimum, the following grab samples will be collected:
• Field Blank: See Section 9.7 for discussion.
• Upstream: A point in the receiving water, upstream of the point of sewage discharge, to capture ambient conditions absent of sewage discharge impacts. • Source: A point in the receiving water where sewage initially enters the receiving water. See Section 9.6 for information on determining velocity of the surface water in order to determine the Source sample location.
• “Downstream” of spill: A point in the receiving water, downstream of the point of sewage discharge, where the spill material is fully mixed with the receiving water. This location will vary with the velocity of the surface water to be sampled (see Section 9.6). 172 / 352
City of Lakeport
Spill Emergency Response Plan 7-27-23
© 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 21 of 43 • A point in a drainage conveyance system before the drainage conveyance system flow discharges into a receiving water.

Sample labels shall be completed for each sample, using waterproof ink.

Photos or video of each sample location will be taken, properly labeled with date, time, and view direction and a map of the photo locations completed. Photos and videos shall include relevant landmarks to identify sampling locations and their surroundings.

Due to the evidentiary nature of samples collected during enforcement investigations, possession must be traceable from the time the samples are collected until they are analyzed. To maintain and document sample possession, a Surface Water Sample Chain of Custody Record (see Sewer Spill/Backup Response Workbook) must be completed. A sample is under custody if:
• It is in your possession, or
• It is in your view, after being in your possession, or • It was in your possession and under your control to prevent tampering, or • It is in a designated secure area.

As few people as possible should handle samples. The person taking the samples is personally responsible for the care and custody of the samples collected until they are transferred or dispatched properly.

Samples are accompanied by a chain of custody record. When transferring the possession of samples, the individuals relinquishing and receiving will sign, date, and note the time on the record. This record documents sample custody transfer from the sampler, often through another person, to the analyst at the laboratory. The samples are typically transferred to the sample-receiving custodian at the laboratory.

9.9 SPILL TECHNICAL REPORT: Spill Technical Report for Individual Category 1 Spill in which 50,000 Gallons or Greater Discharged into a Surface Water
For any spill in which 50,000 gallons or greater discharged into a surface water, within 45 calendar days of the spill end date, the Legally Responible Official shall submit a Spill Technical Report to the online CIWQS Sanitary Sewer System Database. The Spill Technical Report, at minimum, must include the following information:

1. Spill causes and circumstances, including at minimum:
• Complete and detailed explanation of how and when the spill was discovered; • Photographs illustrating the spill origin, the extent and reach of the spill, drainage conveyance system entrance and exit, receiving water, and post-cleanup site conditions; • Diagram showing the spill failure point, appearance point(s), the spill flow path, and ultimate destinations;

All complaint records will be maintained for a minimum of five years in Cartograph whether or not they result in a spill. Spill files (field notes, spill/Backup Response Workbook) are kept on the City server.

11. POST-SPILL ASSESSMENTS OF SPILL RESPONSE ACTIVITIES (ref. State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Element 6, ATTACHMENT D, Page D-6) Every spill event is an opportunity to evaluate the City adherence to response and reporting procedures and effectiveness of the response. Each spill event is unique, with its own elements and challenges including volume, cause, location, terrain, climate, and other parameters.

As soon as possible after spill events all the participants, from the person who received the call to the last person to leave the site, will meet to review the procedures used and to discuss what worked and where improvements could be made in responding to and mitigating future spill events. The results of the debriefing will be documented and tracked to ensure the action items are completed as scheduled.

11.1 FAILURE ANALYSIS INVESTIGATION
The objective of the failure analysis investigation is to determine the “root cause” of the spill and to identify corrective action(s) needed that will reduce or eliminate future potential for the spill to recur or for other spills to occur.

The investigation will include reviewing all relevant data to determine appropriate corrective action(s) for the line segment. The investigation may include:
• Reviewing and completing the Sanitary Sewer Spill Report and any other documents related to the incident • Reviewing the incident timeline and other documentation regarding the incident • Reviewing communications with the reporting party and witness • Reviewing volume estimate, volume recovered estimate, volume estimation assumptions and associated drawings
• Reviewing available photographs
• Interviewing staff that responded to the spill
• Reviewing past maintenance records
• Reviewing past CCTV records,
• Conducting a CCTV inspection to determine the condition of all line segments immediately following the spill and reviewing the video and logs,
• Reviewing any Fats, Roots, Oils, and Grease (FROG) related information or results 178 / 352

Key Definitions & Category Determination A-3: Page 1
NOTE: All references to “SSWDR” refer to State Water Board Order No. WQ 2022-0103-DWQ.

DRAINAGE CONVEYANCE SYSTEM: A drainage conveyance system is a publicly- or privately-owned separate storm sewer system, including but not limited to drainage canals, channels, pipelines, pump stations, detention basins, infiltration basins/facilities, or other facilities constructed to transport stormwater and non-stormwater flows.

SPILL: A spill is a discharge ofsewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Exfiltration of sewage is not considered to be a spill under SSWDR if the exfiltrated sewage remains in the subsurface and does not reach a surface water of the State. • 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 SSWDR that results in a discharge to:
o A surface water, including a surface water body that contains no flow or volume of water; or o 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.

A spill from an City-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the City shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Requirements) of SSWDR.
• 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 SSWDR 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. • 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 SSWDR 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. • 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 SSWDR 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.

WATERS OF THE STATE: Waters of the State are surface waters or groundwater within boundaries of the state as defined in Water Code section 13050(e), in which the State and Regional Water Boards have authority to protect beneficial uses.

Waters of the State include, but are not limited to, groundwater aquifers, surface waters, saline waters, natural washes and pools, wetlands, sloughs, and estuaries, regardless of flow or whether water exists during dry conditions. Waters of the State include waters of the United States.

Does the
spill/backup appear
to be due to a problem
in the Cityowned/maintained
sewer line?
This is a Private Spill

1. Photograph the extent of the discharge and the discharge boundaries if possible.

2. Notify the property owner that the blockage is in their lateral and that the City does not have legal authority to maintain or perform work on privately-owned laterals.

3. Give customer the “Your Responsibilities as a Private Property Owner” pages from this Workbook (F-4).

4. Recommend to customer they hire a contractor to clear their line.

5. If customer is not home:
• Complete Door Hanger and leave on customer’s door.
• Leave a message on the customer’s voicemail.

6. If the property owner is unable or unwilling to address the cause of the Spill, immediately contact your supervisor and discuss whether Code Enforcement, the County Department of Environmental Health or Regional Water Quality Control Board should be notified.

7. If you are directed to, break the stoppage and clean up the private spill. Be sure to document City staff time and equipment used for potential billing purposes and take pictures.

1. Document the service call according to City procedures.

2. STOP. Do not continue to PAGE 2

Spill/Backup Response Flowchart C-1: Page 2

BEGIN DIVERSION AND CONTAINMENT, AS NECESSARY

1. DIVERT AWAY FROM SENSITIVE AREAS:
a. Cover unplugged storm drains w/mats, or use dirt/other material to divert sewage away from sensitive areas (e.g., schools, playgrounds, intersections, etc.)
b. ENSURE PUBLIC CONTACT DOES NOT OCCUR. Use cones/barricades to isolate area.

2. CONTAIN SPILL & RETURN TO SYSTEM, IF POSSIBLE:
a. As practical, plug or block drainage conveyance system entry locations or use rubber mats to cover basin inlet and divert flow to a downstream sanitary sewer manhole (barricade manhole if left open and monitor after barricade) or area suitable to capture the spill for later collection.

If any amount has already reached the drainage conveyance system, trace it downstream to a dry manhole and block it from entering surface waters. i.e., plugs, sandbags, or vacuum truck. b. If you are confident that you can capture the spill in the drainage conveyance system, trace it downstream to a dry manhole and then divert the spill to the drainage conveyance system for later recovery and return to the sanitary sewer.
c. Use bypass pumps to pump around blockage until it can be removed. d. Divert to low area of ground where it can be collected later.

3. PHOTOGRAPH each drainage conveyance system entry location.

ADDRESS CAUSE OF SPILL/BACKUP ASAP

1. For spill/backups not related to a pump station, relieve the stoppage. Note the distance of the obstruction from the manhole and catch/remove debris that could cause another stoppage. After flow has returned to normal, clean the pipe thoroughly. Consider televising (CCTV) the affected line.

2. For pump station related spill/backups refer to that station’s Emergency Response Plan.

3. Photograph staff activities while clearing the blockage.

1. Sample surface waters the spill has reached if safe and if the property owner allows (if the surface water access point is on private property):
• If preliminary volume estimates of the spill are 50,000 gallons or greater, begin collecting as soon as possible but no later than 18 hours after becoming aware of the spill.
• If people are fishing or swimming in the waters, collect samples regardless of the volume of the spill.

2. Refer to and follow the sampling standard operating procedure.

Contain/recover/clean up as much of the spill in the waters and shoreline as possible. Contact Utilities Director to request outside assistance, as appropriate.

NO
YES
Is it feasible/practical
to contain/recover any of the spill from

DRAINAGE CONVEYANCE SYSTEM CLEANING SOP

1. Seal or berm the drainage conveyance system immediately downstream of point the spill reached.

2. Photograph impacted drainage conveyance system before cleaning.

3. Vacuum any visible sewage – Record the volume of sewage recovered. Record volume on the spill report.

4. Flush impacted sections of the drainage conveyance system with 3X amount of spill, if possible, and contain. Record volume of flush water used and volume of flush water returned to the sanitary sewer on Spill Report.

5. Ensure all visible signs of sewage have been removed.

6. Photograph drainage conveyance system after cleaning is completed.

YES
NO
Was drainage
conveyance
system impacted?

IMPACTED AREA CLEANUP, AS NECESSARY

1. Assign staff to begin cleanup. If you might use the area measured volume method to estimate the volume, draw a sketch of the spill footprint and capture dimensions before washing it down.

2. Remove all signs of gross pollution with a shovel, broom, rake, and bucket. (toilet paper, solids, grease, etc.)

3. Flush impacted area with 3X amount of spill, if possible, and contain. Record volume of flush water used and volume of flush water returned to the sanitary sewer on the Spill Report (D-1).

4. Setup berm/other means to contain all water so it can be returned to sewer

5. Don’t use disinfectants if they may enter storm drain system and not be fully recovered or if they may enter surface waters.

6. Address saturated soil with removal and/or in-place treatment, depending on the extent of the contamination, the location, and land use. Take measures to prevent accidental contact by the public.

NOTE: addressing saturated soil may involve returning to the site one or more days after the spill event.

Volume Estimation Computations & Examples E-1: Page 1
Miscellaneous Computations & Examples
To convert inches to feet
(NOTE: for the purposes of
this worksheet, the unit of
measurement will be in
feet for formula examples)
Divide the inches by 12 or use the chart on the right.

Example 1: 27" ÷ 12 = 2.25'
Example 2: 1¾" = ?'
1" (0.08') + ¾" (0.06') = 0.14'
Volume of one cubic foot 7.48 gallons of liquid
Area:

Two-dimensional
measurement represented
in square feet (SQ/FT or
ft2)
Square/rectangle: Area = Length x Width
Circle: Area = π x r2 (where π ≈ 3.14 and r = radius = ½ diameter) Triangle: Area = ½ (Base x Height)
Volume:

Three-dimensional
measurement represented
in cubic feet (CU/FT or ft3)
Rectangle/square footprint: Volume = Length x Width x Depth Circle footprint (cylinder): Volume = π x r2 x Depth
(where π ≈ 3.14 and r = radius = ½ diameter)
Triangle footprint: Volume = ½ (Base x Height) x Depth
Depth:

Wet Stain on Concrete or
asphalt surface
If the depth is not measurable because it is only a wet stain, use the following estimated depths:
o Depth of a wet stain on concrete surface: 0.0026' (1/32") o Depth of a wet stain on asphalt surface: 0.0013' (1/64") These were determined to be a reasonable depth to use on the respective surfaces through a process of trial and error. One gallon of water was poured onto both asphalt and concrete surfaces. Once the area was determined as accurately as possible, different depths were used to determine the volume of the wetted footprint until the formula produced a result that (closely) matched the one gallon spilled. This process was repeated several times.

Depth:

Contained or “Ponded”
sewage
Measure actual depth of standing sewage whenever
possible. When depth varies, measure several representative sample points and determine the average. Use that number in your formula to determine volume.

Volume Estimation: Eyeball Estimation Method (for ≤100 gallons) E-2 Spill Date: Location:

This method is invalid if surface conditions are wet (due to rainfall, irrigation, etc.) DO NOT use this method under these circumstances.

STEP 1: Position yourself so that you have a vantage point where you can see the entire spill.

STEP 2: Imagine one or more buckets or barrels of water tipped over. Depending on the size of the spill, select a bucket or barrel size as a frame of reference. It may be necessary to use more than one bucket/barrel size.

STEP 3: Estimate how many of each size bucket or barrel it would take to make an equivalent spill. Enter those numbers in Column A of the row in the table below that corresponds to the bucket/barrel sizes you are using as a frame of reference.

STEP 4: Multiply the number in Column A by the multiplier in Column B. Enter the result in Column C.

Volume Estimation: Area/Volume Method E-4: Page 3
STEP 7: List assumptions made to arrive at the total estimated spill volume. Adjust estimation up for moderate to severe cracking and/or roughness of surface (General Rule 20% to 40%):

Attach and/or reference system map and identify location of spill and buildings contributing to spill.

STEP 1: Determine the number of Equivalent Dwelling Units (EDUs) for this spill: EDUs NOTE: A single-family residential home = 1 EDU. For commercial buildings, refer to agency documentation.

STEP 2: This volume estimation method utilizes daily usage data based on flow rate studies of several jurisdictions in California. Column A shows how an average daily usage of 180 gallons per day is distributed during each 6-hour period. Adjust the table as necessary to accurately represent the actual data.

Complete Column E by entering the number of minutes the spill was active during each 6-hour time period.

Multiply column D times Column E to calculate the gallons spilled during each time period. Add the numbers in Column F together for the Total Estimated spill Volume per EDU.

Customer Information Letter (Backup Only) F-4 (English) Dear Property Owner:

We recognize that sewer backup incidents can be stressful and require immediate response while all facts concerning how an incident occurred are still unknown. Rest assured that we do all we can to prevent this type of event from occurring in the first place. Nevertheless, occasionally tree roots or other debris in the sewer lines causes a backup into homes immediately upstream of the blockage. At this time the City is investigating the cause of this incident.

If the City is found to be responsible for the incident, we are committed to cleaning and restoring your property, and to protecting the health of those affected during the remediation process.

The cleaning contractor provided by the City has been selected because of their adherence to established protocols that are designed to assure to all parties thorough, cost-effective and expeditious cleaning services. You also have the right to select your own cleaning contractor, but the City does not guarantee payment of fees/expenses incurred and reserves the right to dispute fees/expenses deemed not usual and customary.

Depending on the extent of the backup our Sewer Crew may advise you to consider relocating temporarily while the living area is cleaned. In that case, if the City is found to be responsible for the backup you may submit a claim for reimbursement of reasonable lodging for one night. Additional lodging and other expenses may be discussed with Sierra Pacific Loss Management at (800) 413-2999.

To discuss this matter, or to submit a claim, contact the City Clerk at (707) 263-5615.

Sincerely,
The City of Lakeport

Customer Information Letter (Backup Only) F-4 (Spanish) Estimado Propietario:

Reconocemos que los incidentes de la red de alcantarillado pueden ser estresantes y requieren una respuesta inmediata, mientras que todos los hechos relacionados con la forma en que ocurrió el incidente aún son desconocidos.

Tenga la seguridad de que haremos todo lo posible para evitar que este tipo de evento ocurra en primer lugar. Sin embargo, ocasionalmente las raíces de los árboles u otros residuos en las líneas de alcantarillado causan una copia de seguridad en los hogares inmediatamente antes del bloqueo. En este momento el ciudad está investigando la causa de este incidente.

Si se determina que el ciudad es responsable del incidente, nos comprometemos a limpiar y restaurar su propiedad, ya proteger la salud de las personas afectadas durante el proceso de remediación.

El contratista de limpieza proporcionado por el Distrito ha sido seleccionado debido a su adhesión a los protocolos establecidos que están diseñados para garantizar a todas las partes servicios de limpieza exhaustivos, rentables y rápidos. También tiene derecho a seleccionar su propio contratista de limpieza, pero el ciudad no garantiza el pago de los honorarios / gastos incurridos y se reserva el derecho de disputar los honorarios / gastos que se consideren no habituales y habituales.

Dependiendo de la extensión de la copia de seguridad, nuestro Sewer Crew puede aconsejarle que considere reubicarse temporalmente mientras se limpia la sala de estar. En ese caso, si se determina que el cuidad es responsable de la copia de seguridad, puede presentar una reclamación de reembolso de alojamiento razonable por una noche. El alojamiento adicional y otros gastos pueden discutirse con el Sierra Pacific Loss Management al (800) 413-2999.

Para discutir este asunto, comuníquese con el City Clerk al (707) 263-5615. Para presentar un reclamo por daños comuníquese con la City Clerk al (707) 263-5615.

Your Responsibilities as a Private Property Owner (Backup Only) F-5: Page 1 How a Sewer System Works
A property owner's sewer pipes are called service laterals and are connected to larger local main and regional trunk lines. Service laterals run from the connection at the home to the connection with the public sewer. Depending on your location, a portion of the lateral is the responsibility of the property owner and must be maintained by the property owner.

How do sewage spills happen?
Sewage spills occur when the wastewater in
underground pipes spills through a manhole, cleanout,
or broken pipe. Most spills are relatively small and can be stopped and cleaned up quickly, but left unattended
they can cause health hazards, damage to homes and
businesses, and threaten the environment, local
waterways, and beaches. Common causes of sewage
spills include grease build-up, tree roots,
broken/cracked pipes, missing or broken cleanout
caps, undersized sewers, and groundwater/rainwater
entering the sewer system through pipe defects and
illegal connections.

Prevent most sewage backups with a Backflow Prevention Device This type of device can help prevent sewage backups into homes and businesses. If you don’t already have a Backflow Prevention Device, contact a professional plumber or contractor to install one as soon as possible.

Is my home required to have a backflow prevention device? Section 710.1 of the Uniform Plumbing Code (U.P.C.) states: “Drainage piping serving fixtures which have flood level rims located below the elevation of the next upstream manhole cover or private sewer serving such drainage piping shall be protected from backflow of sewage by installing an approved type of backwater valve.” The intent of Section 710.1 is to protect the building interior from mainline sewer spills or surcharges.

Additionally, U.P.C. 710.6 states:
“Backwater valves shall be located where
they will be accessible for inspection and
repair at all times and, unless
continuously exposed, shall be enclosed
in a masonry pit fitted with an
adequately sized removable cover.”

Your Responsibilities as a Private Property Owner (Backup Only) F-5: Page 2 Spill cleanup inside the home:

For large clean ups, a professional cleaning firm should be contacted to clean up impacted areas, If you hire a contractor, it is recommended to get estimates from more than one company. Sometimes, homeowner’s insurance will pay for the necessary cleaning due to sewer backups. Not all policies have this coverage, so check with your agent.

If you decide to clean up a small spill inside your home, protect yourself from contamination by observing the following safety measures. Those persons whose resistance to infection is compromised should not attempt this type of clean up.

Other Tips:
• Keep children and pets out of the affected area.

Sus Responsabilidades Como Propietario de Una Propiedad Privada F-5 Página 1: en español Cómo funciona un sistema de alcantarillado
Las tuberías de alcantarillado de un propietario se denominan servicios laterales y están conectadas a líneas troncales principales y regionales locales más grandes. Los servicios laterales se ejecutan desde la conexión en el hogar hasta la conexión con el sistema de alcantarillado del Distrito. Estos laterales son responsabilidad del propietario y deben ser mantenidos por el propietario.
¿Cómo ocurren los derrames de aguas residuales?
Los derrames de aguas residuales ocurren cuando las aguas residuales en las tuberías subterráneas se desbordan a través de un pozo de acceso, limpieza o tubería rota. La mayoría de los derrames son relativamente pequeños y se pueden
detener y limpiar rápidamente, pero si se los deja
desatendidos, pueden causar riesgos para la salud, dañar viviendas y negocios y amenazar el medio ambiente, las vías fluviales locales y las playas. Las causas comunes de
derrames de aguas residuales incluyen acumulación de
grasa, raíces de árboles, tuberías rotas / agrietadas, tapas de limpieza faltantes o rotas, alcantarillas de tamaño
insuficiente y aguas subterráneas / pluviales que ingresan al sistema de alcantarillado a través de defectos en las tuberías y conexiones ilegales.

Prevenga la mayoría de las copias de seguridad de aguas residuales con un dispositivo de prevención de reflujo Este tipo de dispositivo puede ayudar a prevenir las copias de seguridad de aguas residuales en hogares y empresas.

Si aún no tiene un dispositivo de prevención de reflujo, comuníquese con un plomero o contratista profesional para instalar uno lo antes posible.
¿Se requiere que mi hogar tenga un dispositivo de prevención de reflujo? La Sección 710.1 del Código Uniforme de Plomería (UPC) establece: “Los accesorios de tuberías de drenaje que tienen llantas de nivel de inundación ubicadas debajo de la elevación de la siguiente boca de alcantarilla corriente arriba o la alcantarilla privada que atiende dicha tubería de drenaje deben protegerse contra el reflujo de aguas residuales al instalar un tipo de válvula de evacuación ”. La intención de la Sección 710.1 es proteger el interior del edificio de los desagües o sobrecargas de alcantarillado de la línea principal.

Adicionalmente, U.P.C. 710.6 dice: Las válvulas de aguas residuales deben ubicarse donde puedan ser inspeccionadas y reparadas en todo momento y, a menos que estén continuamente expuestas, deben estar encerradas en un pozo de mampostería equipado con una cubierta removible del tamaño adecuado.

Sus Responsabilidades Como Propietario de Una Propiedad Privada F-5 Página 2: en español Limpieza de derrames dentro de la casa:

Para grandes limpiezas, se debe contactar a una empresa de limpieza profesional para limpiar las áreas afectadas. Si contrata a un contratista, se recomienda obtener estimaciones de más de una compañía. A veces, el seguro del propietario de vivienda pagará la limpieza necesaria debido a las reservas de alcantarillado. No todas las pólizas tienen esta cobertura, así que consulte con su agente.

Si decide limpiar un pequeño derrame dentro de su casa, protéjase de la contaminación observando las siguientes medidas de seguridad. Aquellas personas cuya resistencia a la infección esté comprometida no deben intentar este tipo de limpieza.

Otros consejos:
o Mantenga a los niños y mascotas fuera del área afectada. o Apague los sistemas de calefacción / aire acondicionado o Use botas de goma, guantes de goma y gafas durante la limpieza. o Deseche los artículos que no se puedan lavar y desinfectar (como: colchones, alfombras, cosméticos, juguetes, etc.)
o Retire y deseche los paneles de yeso y el aislamiento contaminado con aguas residuales o aguas de inundación.
o Limpie a fondo todas las superficies duras (como pisos, concreto, molduras, muebles de madera y metal, mostradores, electrodomésticos, fregaderos y otros accesorios de plomería) con agua caliente y ropa o detergente para platos.
o Ayude al proceso de secado con ventiladores, unidades de aire acondicionado y deshumidificadores. o Después de completar la limpieza, lávese las manos con agua y jabón. Use agua que haya sido hervida por 1 minuto (deje que el agua se enfríe antes de lavarse las manos) O use agua que haya sido desinfectada (solución de 1/8 cucharadita de lejía doméstica por 1 galón de agua). Dejar reposar durante 30 min. Si el agua está turbia, use ¼ cucharadita de lejía de uso doméstico por 1 galón de agua. o Lave la ropa usada durante la limpieza con agua caliente y detergente (lave aparte de la ropa no contaminada).

o En áreas de superficies duras como el asfalto o el concreto, es seguro usar una solución de lejía al 2%, o ½ taza de lejía a 5 galones de agua, pero no permita que llegue a un drenaje de tormenta ya que la lejía puede dañar la ambiente.
o Después de la limpieza, lávese las manos con agua y jabón. Use agua que haya sido hervida por 1 minuto (deje enfriar antes de lavarse las manos) O use agua que haya sido desinfectada (solución de 1/8 cucharadita de cloro por 1 galón de agua). Dejar reposar durante 30 min. Si el agua está turbia, use ¼ cucharadita de lejía de uso doméstico por 1 galón de agua. o Lave la ropa usada durante la limpieza con agua caliente y detergente (lave aparte de la ropa no contaminada).
