INTRODUCTION

1.1 Regulation of Sewer System Overflows and Spills
Overview City of San Clemente Wastewater Operations. The San Clemente Water Reclamation Plant (SCWRP) treats wastewater from a service area that covers a significant majority of the incorporated area of the City of San Clemente. SCWRP recycled water treatment and reuse operations are regulated by the Regional Water Quality Control Board, San Diego Region (RWQCB) Order No. R9-2003-0123. In accordance with requirements of RWQCB Order No. R9-2003-0123, SCWRP produces tertiary treated recycled water that is used for irrigation at the San Clemente Municipal Golf Course, the Pacific Golf Course, and other approved sites within the San Clemente Hydrologic Area.

SCWRP secondary effluent flows in excess of recycled water demands are discharged to the South Orange County Wastewater Authority (SOCWA) San Juan Creek Ocean Outfall (SJCOO) via the San Clemente Land Outfall. The SCWRP discharge to the SJCOO is regulated by RWQCB Order No. R9-2022-0005. 1 Sewer System Management Requirements. City of San Clemente wastewater collection operations are regulated under State Water Resources Control Board (SWRCB) Order No. WQ 2022-0103-DWQ.2 Order No. WQ 2022-0103-DWQ establishes state-wide requirements governing sewer collection system operations, management, performance, reporting and notification. The requirements of Order No.

WQ 2022-0103-DWQ are directed toward minimizing the potential for spills from sewer facilities. Order No. WQ 2022-0103-DWQ defines a sewer system spill (also known as a sanitary sewer overflow or SSO) as a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, or infrastructure failure.3 Order No. WQ 2022-0103-DWQ prohibits spills,
requires the reporting of spills through a statewide electronic4 reporting system, and requires sewer agencies to maintain and update Sewer System Management Plans (SSMPs).

In accordance with SWRCB requirements, the City of San Clemente maintains an SSMP that details the systems, operations, and procedures the City has implemented to prevent spills from the City’s sewer collection facilities. The City’s current SSMP was adopted in 2019.5

1 RWQCB Order No. R9-2022-0005 (NPDES CA01007417) was adopted by the RWQCB on March 9, 2022. 2 SWRCB Order No. WQ 2022-0103-DWQ was adopted by the SWRCB on December 6, 2022 and became effective on June 5, 2023. Order No. WQ 2022-0103-DWQ supersedes SWRCB Order 2006-0003-DWQ (as amended by SWRCB Order No. 2013-0058-EXEC) which had previously regulated spills from sanitary sewer systems. 3 Definition of a spill is presented within Attachment A to Order No. WQ 2022-0103-DWQ. Exfiltration of sewage is not considered a spill under Order No. WQ 2022-0103-DWQ, provided that the exfiltrated sewage remains in the subsurface and does not reach a surface water. 4 California Integrated Water Quality System (CIWQS).
5 SWRCB Order No. WQ 2022-0103-DWQ requires SSMPs to be updated by August 2, 2025, and thereafter on a six-year basis.

City of San Clemente Chapter 1
Utilities Division Introduction
Spill Emergency Response Plan Page 1 - 2 May 2023
Spill Emergency Response Plan (SERP) Requirements. Order No. WQ 2022-0103-DWQ also requires the City to maintain and update a Spill Emergency Response Plan (SERP) that details measures to respond to spills in a timely manner, protect public health and the environment and to terminate, intercept, recover, and clean up sewage spills. Order No. WQ 2022-0103-DWQ requires that SERPs identify sewer agency measures and procedures to:
• Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner.
• Notify other potentially affected entities (for example, health agencies, water suppliers, etc.) of spills that potentially affect public health or reach waters of the State. • Comply with the notification, monitoring, and reporting requirements of Order No.

WQ 2022-0103-DWQ, state laws and regulations, and applicable RWQCB Orders. • Ensure that appropriate staff and contractors implement the SERP and that responding spill staff and contractors are appropriately trained.
• Address emergency system operations, traffic control and other necessary response activities. • Contain the spill and prevent/minimize discharge to waters of the State or any drainage conveyance system.
• Minimize and remediate public health impacts and adverse impacts on beneficial uses of waters of the State.
• Remove sewage from the drainage conveyance system.
• Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters.
• Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery.
• Implement pre-planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event.

1.2 Purpose of Spill Emergency Response Plan
This City of San Clemente SERP is implemented by the City of San Clemente to ensure compliance with provisions of SWRCB Order No. WQ 2022-0103-DWQ. 6 To this end, this updated SERP documents emergency measures, policies, procedures, and plans implemented by the City to respond to respond to sewer system spills or threatened spills and to minimize impacts resulting from the spills. The updated Spill Emergency Response Plan presented herein supersedes the City's previous spill emergency response plan (2019 update), and documents policies and procedures used by City of San Clemente Utilities Division staff to:
• Detect sewer system spills or overflows.
• Assess the cause, source, and nature of the spills.
6 This 2023 version of the City’s SERP is developed in accordance with requirements of SWRCB Order No. WQ 2022-0103-DWQ and supersedes the Sanitary Sewer Overflow (SSO) Spill Prevention and Response Plan adopted by the City in 2019, which was developed in accordance with requirements of the prior SWRCB Order No. 2006-0003-DWQ, as amended by Order No. WQ 2013-0058-EXEC.

City of San Clemente Chapter 1
Utilities Division Introduction
Spill Emergency Response Plan Page 1 - 3 May 2023
• Identify equipment and manpower required to respond to the spills. • Take actions to contain the spilled sewage and protect public health. • Comply with the notification, monitoring, reporting, and record-keeping requirements established within SWRCB Order No. WQ 2022-0103-DWQ.
• Perform any necessary posting or public notification. • Take actions to correct the problem causing the spill. • Clean up the spilled sewage and restore affected areas to pre-spill conditions. • Document causes of the spill, preventative measures taken, and impacts associated with the spill. • Assess the cause/source of the spill and modify prevention or response actions to minimize the potential for recurrence.

In addition to addressing notification, reporting, monitoring, and record-keeping requirements established in SWRCB Order No. WQ-2022-0101-DWQ, this updated plan also incorporates experience gained by Utilities Division staff in responding to previous spill events.

1.3 Preparation of Spill Emergency Response Plan

SPILL DETECTION

2.1 Overview of Wastewater Collection System
The City of San Clemente Utilities Division wastewater service area is comprised of approximately 14.3 square miles. The Utilities Division service area represents approximately 84 percent of the total 17.1 square-mile incorporated area of the City of San Clemente. Wastewater service within the remaining portions of the City of San Clemente is provided by the South Coast Water District and Santa Margarita Water District.

The sewer service area tributary to the SCWRP includes land within seven topographic drainage areas.

Key trunk mains serving the seven drainage regions include:
• Camino De Los Mares Trunk (Drainage Region 1).
• Avenida Pico Trunk (Drainage Region 2).
• Frontera Trunk (Drainage Region 3).
• El Camino Real North Trunk (Drainage Region 4).
• San Gabriel Trunk (Drainage Region 5).
• Pacific Coast Highway Trunk (Drainage Region 6).
• Beach Trunk (Drainage Region 7).

Wastewater collected from Drainage Regions 1, 4, 6, and 7 is transported via gravity and force mains to the Main Pump Station (located near Avenida Pico and El Camino Real). Wastewater collected from Drainage Regions 2, 3, and 5 is transported via gravity and force mains to the Los Molinos Pump Station (located along Avenida Pico west of Interstate 5). The Main Pump Station and Los Molinos Pump Station lift the collected wastewater to the SCWRP.

The City maintains eight local pump stations within the SCWRP tributary area which lift wastewater within portions of the seven drainage regions:
• La Pata Pump Station (Drainage Region 2).
• Frontera Pump Station (Drainage Region 3).
• Colina Rodante Pump Station (Drainage Region 3).
• San Gabriel Pump Station (Drainage Region 5).
• Colombo Pump Station (Drainage Region 5).
• Cypress Shores Pump Station (Drainage Region 7).
• La Ramba Pump Station (Drainage Region 7).
• Linda Lane Pump Station (Drainage Region 7).

City of San Clemente Chapter 2
Utilities Division Spill Detection
Spill Emergency Response Plan Page 2 - 2 May 2023
The City also maintains the Liberty Park Pump Station, which is located within the City limits but is outside the tributary area of the SCWRP. The Liberty Park Pump Station conveys wastewater to the Santa Margarita Water District through an interagency agreement between the City and Santa Margarita.

The City maintains an updated atlas that details all sewer collection system facilities. The sewer system atlas shows the location of gravity mains, manholes, force mains, and other facilities. A master electronic version of the City's sewer system atlas is maintained on the City's computer network, and copies are backed up weekly. Copies of the atlas are carried on City response vehicles.

Spill Prevention. As part of its SSMP, the City has developed and implemented an action plan to minimize the potential for spills that includes procedures regarding inspection, preventative maintenance, system operations, public education, capital improvements, monitoring and reporting, forensic assessment, and system audits.

2.2 Potential Spill Sources and Methods of Detection
As part of developing its SSMP, Utilities Division staff assessed prior spills, shared information with other regional agencies, evaluated historic and potential sewer spill causes, and researched state-wide spill reports to identify potential causes of spills. Potential causes of sewer spills within the City's sewer system include:
• Sewer gravity main breaks or failures.
• Sewer gravity main blockages.
• Sewer gravity main surcharging.
• Pressure main rupture.
• Pump station pump/motor/control failure.
• Pump station electrical failure.
• Pump station surcharging.

Gravity Sewer Main Breaks. Spills may be caused by failure (breaks) in gravity sewer mains. Potential causes of gravity sewer main failure may include:
• Penetrating tree roots.
• Corrosion
• Pipe wall or pipe joint failure.
• Inadequate sewer main installation/construction.
• Construction excavation activities.
• Earth slides or earth movement.

Spills resulting from sewer main breaks would result in either wastewater overflowing from the manhole immediately upstream from the break or wastewater flowing to the surface at or downstream from the point of the break. Virtually all City of San Clemente gravity mains are located in City streets. As a result, spills resulting from sewer main breaks are likely to be quickly noticed by the public or personnel within other City of San Clemente Departments. Utilities Division personnel also monitor for breakrelated spills through flow monitoring data generated at wastewater pump stations and at the SCWRP.

City of San Clemente Chapter 2
Utilities Division Spill Detection
Spill Emergency Response Plan Page 2 - 3 May 2023
Gravity Sewer Main Blockages. The potential exists for spills to occur as a result of blockages or clogs within gravity sewer mains or manhole structures. Such blockages or clogs could be caused by • Penetrating roots through pipe joints or pipe walls.
• Penetrating roots through connections with private service laterals. • Grease or other congealing or viscous substances.
• Rags, paper, plastic bags, or other semi-solid debris. • Solid material or debris.
• Pipe wall failure.
• Vandalism.

Spills resulting from sewer main blockages or clogs would result in wastewater overflowing from the manhole immediately upstream from the blockage. Virtually all City of San Clemente gravity mains are in City streets in highly-visible areas. As a result, visual inspection of City wastewater facilities by Utilities Division staff represents a key means of detection for blockage-related spills.

Spills resulting from sewer main blockages are likely to be quickly noticed by the public or personnel within other City of San Clemente Departments. The Utilities Division also monitors for blockage-related spills through flow monitoring data generated at wastewater pump stations and at the SCWRP.

Gravity Sewer Main Surcharging. As documented in the City's SSMP, scheduled City of San Clemente Utilities Division capital improvements have kept pace with development and wastewater flows within the City of San Clemente. As a result, no City of San Clemente sewer mains are at risk for surchargerelated spills during dry weather. Sewer mains are also sized to handle maximum anticipated wet-weather wastewater flows plus infiltration and inflow (I&I).

Spills resulting from sewer main surcharges would result in wastewater overflowing from manholes. As noted, virtually all City of San Clemente gravity mains are located in City streets in highly-visible areas.

Visual inspection of City wastewater facilities by Utilities Division staff and reports from the public or other City of San Clemente departments thus represents a key means of detecting surcharge-related spills.

The Utilities Division also monitors for surcharge-related spills through flow monitoring data generated at wastewater pump stations and at the SCWRP. Additionally, many of the key gravity mains are equipped with telemetered manhole covers which provide City staff with real-time monitoring data on flows and water levels in manholes and provide alerts to City staff when conditions of unusual flow or water levels are detected.

Pressure Main Ruptures. The potential exists for spills to occur as a result of pressure main ruptures.

Pressure main ruptures could be caused by:
• Corrosion.
• Pipe wall failure or joint failure.
• Inadequate installation/construction.
• Pressure build-up from blockages.
• Construction excavation activities.
• Earth movement.

City of San Clemente Chapter 2
Utilities Division Spill Detection
Spill Emergency Response Plan Page 2 - 4 May 2023
Spills resulting from pressure main breaks would result from pressurized wastewater breaking the ground surface in the immediate vicinity of the pressure main break. Since virtually all City of San Clemente pressure mains are located along roads or in areas with high foot and/or vehicle traffic, pressure main breaks would be visually recognizable. In addition to being highly visible, pressure main breaks would be detectable through pump station flow rate and pumping pressure data, and flow data monitored at SCWRP. As a result, pressure main ruptures would typically be rapidly detected.

Pump Station Pump/Motor/Control Failure. To minimize the potential for spills caused by pump station pump or motor failures, each of the City's wastewater pump stations is equipped with multiple pump/motors, with at least one pump/motor combination being on standby for use in the event of failure or maintenance of any of the other pump/motor combinations. To minimize the potential for spills resulting from failure of pump station controls, each of the pump stations can be operated under automatic controls or by manual actuation. Additionally, the City's Supervisory Control and Data Acquisition (SCADA) system allows for remote monitoring of pump station pumps, motors, pressures, flows, wet well water levels, and alarms. The SCADA system also allows for remote operation of pump station equipment and operating parameters.

For a spill to occur as a result of pump station pump, motor, or control failure, such failure would have to be comprehensive and affect multiple pumping units and control systems. Spills resulting from such a comprehensive failure would be detectable to City crews through pump station alarms and remotely accessed pump station performance data. Additionally, all City of San Clemente pump stations are located in highly-visible areas, and visual reports of the spill would be quickly noted by Utilities Division staff, other City of San Clemente personnel, or the public.

Pump Station Electrical Outages. Eight of the City's ten wastewater pump stations are equipped with standby power generators that automatically actuate in the event of power failure. Emergency power is not needed at the two remaining pump stations, as wastewater can be diverted by gravity main around the San Gabriel Pump Station, and wet well capacity at the Columbo Pump station is sufficiently large compared to the small wastewater inflows to negate the need for onsite emergency power.

With the presence of emergency onsite generators at the City's wastewater pump stations, a power failure spill could not occur unless failure of an onsite emergency power generator occurred simultaneously with failure of the local electrical power grid. To minimize the potential for such an occurrence, Utility Division crews routinely perform scheduled checks of onsite emergency power generating equipment, and routinely exercise the emergency power generators to insure that they are in proper working order.

The City also maintains mobile emergency power generators for use in the event of failure of any of the onsite pump station generators.

Simultaneous failure of the power grid and emergency generators would be rapidly detectable to City crews through pump station alarms and remotely accessed pump station performance data. It is probable that Utilities Division crews would be alerted to the power failure in advance of occurrence of any spill. Additionally, all City of San Clemente pump stations are sited in highly-visible areas, and visual reports of any spill would be quickly noted by Utilities Division staff, other City of San Clemente personnel, or the public.

City of San Clemente Chapter 2
Utilities Division Spill Detection
Spill Emergency Response Plan Page 2 - 5 May 2023
Pump Station Surcharging. Major upgrades to several of the City's ten wastewater pumping stations have recently been completed, and scheduled City of San Clemente Utilities Division capital improvements have kept pace with anticipated future development and projected wastewater flows within the City of San Clemente. With these recent upgrades, risks associated with surcharge-related spills are minimized.

Spills caused by pump station surcharging would be expected to occur only during times of comprehensive system failure during wet weather periods (such as the rupture of a gravity main or flood-related infiltration to manholes).

Spills resulting from pump station surcharges would result in wastewater overflowing from the pump station, and would be instantly detectable to City crews through pump station alarms and remotely accessed pump station performance data. Additionally, since City of San Clemente pump stations are sited in highly-visible areas, visual reports of any such surcharge-related spill would be quickly noted by Utilities Division staff, other City of San Clemente personnel, or the public.

2.3 Target Response Times
Figure 2-1 (page 2-6) presents the City's spill response chain of command. City of San Clemente Utilities Division staff monitor telephones 24-hours per day, 7 days per week to receive reports of spills, potential spills, or threatened spills.

Spills Reported During Business Hours. Spill reports received during business hours are instantly forwarded to the Sewer/Storm Drain Collections Chief Operator and the Utilities Manager. The Sewer/Storm Drain Collections Chief Operator is responsible for organizing and mobilizing work crews.

On days or times Sewer/Storm Drain Collections Chief Operator is for some reason unavailable, the Assistant Utilities Manager shall designate an alternate person as being on call and responsible for organizing and mobilizing response crews.

It is the City of San Clemente's goal to respond as rapidly as possible to reports of spills or threatened spills. Response times for Utilities Division staff to reach spill sites will vary by location, day of the week, and time of day. Utilities Division work/inspection crews are routinely on patrol within the City during business hours, and cell phone or radio communications are used to identify the location of available personnel. During business hours, depending upon location, the nearest crew may be able to arrive on the scene of a reported spill site within a matter of a few minutes after the spill report is first received.

If no crew is in the immediate area of the spill, Utilities Division management can immediately mobilize a response crew from onsite staff or staff engaged in offsite activities. The Utilities Division headquarters and yard is located on Avenida Pico at the SCWRP. Because of the central location of the Utilities Division headquarters within the sewer service area, maximum travel time from the Utilities Division headquarters on Avenida Pico to the farthest reaches of the City is approximately 20 minutes. Travel time from the Utilities Division site to either of the two principal wastewater pumping stations (Main Pump Station and Los Molinos) is approximately 5 minutes.

Spill Emergency Response Plan Page 2 - 7 May 2023
Spills Reported During Non-Business Hours. As noted, San Clemente staff monitor telephones 24-hours per day, 7 days per week to receive reports of spills, potential spills, or threatened spills.

During non-business hours (night times, weekends, and holidays), the Sewer/Storm Drain Collections Chief Operator schedules an emergency response crew as being on call and available to respond to spill reports. Spill reports during non-business hours are instantly forwarded via cell phone to the collections system stand-by staff, who then notify the Sewer/Storm Drain Collections Chief Operator and the Utilities Manager. Mobilization times during non-business hours vary, depending upon personnel travel times and time of day.

During non-business hours, the City endeavors to achieve a goal of first response and spill site assessment within 30 minutes. The City further endeavors to achieve a goal of having a response team at the site within one hour of receipt of the spill report. If initial assessment indicates the need for more crews than are on call, Utilities Division collections supervisors are empowered to authorize overtime and mobilize any required off-duty personnel to respond to the spill.

B Normal duties of the listed personnel may also include water system operations, but the personnel are available on call to assist with collection system spill responses.

C In addition to the City of San Clemente Utilities Division staff shown above, Sheriff's Department personnel will be called to assist with site and traffic control. Additional work crews from other City departments may also be called in to assist in the spill effort.

D The City of San Clemente maintains interagency “mutual aid” agreements with adjoining agencies (South Coast Water District and Santa Margarita Water District) which allow agencies in need to call upon emergency support staff and resources from adjoining agencies in the event of need.

When Utilities Division staff arrive at the spill scene in advance of the designated Onsite Supervisor, the senior onsite Utilities Division staff member will assume the duties of the Onsite Supervisor until the Sewer/Storm Drain Collections Chief Operator arrives.

When the Sewer/Storm Drain Collections Chief Operator is on vacation or are otherwise unavailable, the Assistant Utilities Manager shall designate an experienced Utilities Division staff member to serve as the on call Onsite Supervisor responsible for responding to and taking charge of spill response efforts. Any City of San Clemente Chapter 3
Utilities Division Equipment and Personnel
Spill Emergency Response Plan Page 3 - 3 May 2023
received spill reports shall be immediately directed to the designated oncall Onsite Supervisor as well as the Utilities Manager.

Response Teams. All Utilities Department workers are available via cell phone/radio communications during business hours. As discussed in Section 2.3 (pages 2-5 through 2-7), Utilities Department supervisors can quickly mobilize spill response crews by (1) routing crews already in the field to the response site and/or (2) directing crews at Utilities Division offices/yards to the response site.

The Sewer/Storm Drain Collections Chief Operator is to ensure that schedules are maintained so that a senior-level Utilities Supervisor and an emergency response crew is scheduled as being on call and available during all non-business hours.

3.2 Training
Utilities Division personnel spill response training is the responsibility of the Utilities Manager, Assistant Utilities Manager, and Utilities Operations Supervisor - Wastewater. Ongoing Utilities Division training includes:
• Orientation Training and Mentorship. New employees are trained in assigned duties by experienced Utilities Division staff. Supervisors serve as mentors in order to allow newer employees to better understand City wastewater facilities, staffing responsibilities, and wastewater system operations.
• Specialized Training. Using either Utilities Division staff or outside instructors, Utilities Division personnel receive periodic training in such areas as first aid, safety (including confined space entry and ventilation), fire prevention, traffic control, and equipment operation. • Coordination with Storm Drain Staff. Since storm drains with the City of San Clemente are maintained by City, City storm drain and wastewater staff routinely coordinate and cooperate in preparing for and responding to spill events.
• Drills and Test Exercises. Utilities Division drills and training exercises are periodically conducted by senior Utilities Division staff. Table 3-2 (page 3-4) presents the Utilities Division training schedule for drills and tests. Drills and test exercises directed by senior Utilities Division staff include notification tests, equipment tests, communication tests, mobility drills, and troubleshooting training. • Professional Training and Certification. Utilities Division employees are encouraged to achieve professional certifications and participate in such professional organizations as Water Environment Federation and California Water Environment Association. Employees are encouraged to attend training sessions and seminars that relate to sewer system operation, spill prevention, spill containment, and spill recovery.
• Professional Development. Professional promotions within the Utilities Division are, in part, based on employee's work performance, professional certifications, and well-rounded knowledge of all facets of the City's wastewater facilities and operations. Employees seeking advancement are thus encouraged to (1) cross-train in areas beyond their normal duties and (2) increase their breadth of knowledge outside their immediate responsibilities.

Spill Categories
Category A Description
Category 1
A discharge of untreated or partially treated wastewater from sanitary sewer system facilities in any volume that:
• Reaches surface waterB and or reaches a drainage channel tributary to a surface water. • Discharges to a Municipal Separate Storm Sewer System (MS4) and is not fully captured and returned to the sanitary sewer system (unless discharged to a dedicated infiltration basin or percolation pond).

Category 2
A discharge of untreated or partially treated wastewater from sanitary sewer system facilities of 1000 gallons or more resulting from a sanitary sewer system failure or flow condition that does not reach surface water, a drainage channel, or a MS4 unless the entire spill discharged to a storm drain system if fully recovered and properly disposed. B A spill of 1000 gallons or more 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 A discharge of untreated or partially treated wastewater from sanitary sewer system facilities of less than 1000 gallons but more than 50 gallons that does not discharge to surface water. C Category 4 A discharge of untreated or partially treated wastewater from sanitary sewer system facilities of less than 50 gallons that does not discharge to surface water. D Table 4-1 Notes:

A Spill categories are defined within Section 5.13.1 of SWRCB Order No. WQ-2022-0103-DWQ B 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 dedicates stormwater infiltration basin or facility.

C A spill of more than 50 but less than 1000 gallons that is caused by a failure or blockage in the sanitary sewer system is a Category 3 spill.

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

Following the initial notification to OES, the Utilities Division shall provide updates to OES on any substantial changes in the estimated volume of untreated or partially treated wastewater or any substantial changes to known impacts. This notification shall be made by the Onsite Supervisor if such substantial changes are in evidence while City crews are still on the scene responding to the spill. The Sewer/Storm Drain Collections Chief Operator shall make the report to OES if such substantial changes City of San Clemente Chapter 4
Utilities Division Spill Response Actions
Spill Emergency Response Plan Page 4 - 4 May 2023
are determined to have occurred after City response crews have left the site but prior to the time the spill report is logged into the California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database.

Order No. WQ-2022-0103-DWQ encourages (but does not require) sewer system operators to notify OES of discharges to surface waters exceeding 1000 gallons from private lateral sewer discharges (PLSDs).8

In accordance with this directive, the City shall endeavor to notify OES whenever City staff become aware of PLSDs to surface waters that exceed 1000 gallons.

RWQCB Notification. RWQCB Order No. R9-2007-005 establishes spill reporting requirements in addition to state-wide spill reporting requirements established in SWRCB Order No. WQ 2002-0103-DWQ.

RWQCB Order No. R9-2007-0005 requires agencies to notify the RWQCB via telephone or email within 24 hours9 of becoming aware of a spill of 1000 gallons or more from a public sewer system or private lateral that reaches surface waters. The RWQCB notification is to include:
• The name of the sewer agency.
• The name and telephone number of the agency person reporting the spill. • The estimated spill volume.
• The location of the spill and the affected receiving water. • The start time of the spill and (if applicable) the end time of the spill. • Confirmation that the local health agency has been notified.

4.4 Site Perimeter and Traffic Control
Site Perimeter Control. Concurrent with the initial assessment, the Onsite Supervisor shall take immediate actions to isolate the public from the spill. Site control shall be achieved using portable barriers, signs or postings, stakes and tape, existing fencing, parked vehicles, or natural terrain.

The Onsite Supervisor shall contact the Sheriff's department if additional assistance is (1) required for isolating the public from the spill, (2) required for controlling crowds or onlookers, or (3) if members of the public are interfering with efforts of the spill response team.

Traffic Control. If the potential exists for spill response actions (or parked response vehicles) to impact traffic, the Onsite Supervisor shall also take actions to divert traffic around the response site and ensure the safety of traffic, the public, and response crews. Traffic shall be diverted where necessary using traffic cones, portable signs, emergency lights, flag personnel, vehicles, and/or portable traffic-direction light trailers.

City response vehicles routinely carry traffic cones, barriers, and traffic control flags, and signs.

Additional materials required to secure the site perimeter (which include portable traffic-direction light trailers) are stored at the SCWRP and should be secured by the Onsite Supervisor if required. 8 Per Section 5.15 of Order No. WQ 2022-0103-DWQ, reporting of spills from privately-owned laterals or systems is voluntary. 9 Provided that such 24-hour notification can be provided without substantially impeding cleanup or other emergency measures.

City of San Clemente Chapter 4
Utilities Division Spill Response Actions
Spill Emergency Response Plan Page 4 - 5 May 2023
The Onsite Supervisor shall determine if onsite traffic control is adequate, or if law enforcement assistance is required. Sheriff's Department officials should be notified if required to assist in traffic control. Fire Department officials should be contacted if traffic controls could result in fire response delays. Response vehicles and crews are required to maintain current telephone numbers for the Sheriff's Department and Fire Department.

4.5 Spill Containment or Diversion
Upon achieving control of the site perimeter, response crews under the direction of the Onsite Supervisor shall endeavor to contain or divert the spill. To determine the best strategy (or strategies) for spill containment or diversion, the Onsite Supervisor shall evaluate the:
• Spill volume and flowrate of the spill.
• Terrain and natural barriers.
• Locations of downstream manholes or other sewer collection sewer facilities. • Locations or storm drains or streams.

Spill and recovery containment strategies to be evaluated, and (if appropriate) implemented by the response crews include:
• Using Vactor trucks to vacuum the spill.
• Using sandbags rubber dams, or other portable flow barriers to prevent the flow from entering storm drains or drainage channels.
• Diverting the spill by pumping around the overflow point or sewer break point back into the sewer system.
• Diverting the spill by berms or sandbags back into the sewer system. • Diverting or retaining the spill in a hollow, swale, or low area for subsequent recovery. • Constructing a temporary dam or dike to contain the spill for subsequent recovery.

Recovery from Storm Drains. City response vehicles are equipped with maps of municipal storm drain facilities. If the spill enters a storm drain, the Onsite Supervisor shall make all reasonable efforts identify a downstream location(s) where the storm drain can be dammed up to prevent the spill from reaching surface waters. The onsite supervisor will also contact the City’s storm drain supervisor to coordinate any response actions involving City storm drain facilities. Any spilled flow contained within the storm drain facilities shall be subsequently removed by portable pumps or Vactor trucks and discharged to the sanitary sewer system.

Recovery Through Streamflow Diversion Facilities. As a means of minimizing the potential for dry season storm drain flow to impact local beaches, the Utilities Division maintains a program of diverting dry season streamflow back into the sanitary sewer system at the following locations:
• Linda Lane Park Diversion.
• North Beach Diversion.
• M02 Diversion.
• Outlet Diversion.

City of San Clemente Chapter 4
Utilities Division Spill Response Actions
Spill Emergency Response Plan Page 4 - 6 May 2023
• Avenida da la Riviera Diversion.
• San Gabriel Diversion.

The Onsite Supervisor shall determine if the spills are in areas tributary to these streamflow diversion facilities. If so, the Onsite Supervisor shall ensure that streamflow diversion facilities are operational and that spilled flows not otherwise contained are recovered through the streamflow diversion facilities.

4.6 Posting
City response vehicles are equipped with signage for use in warning the public of contact with areas contaminated by spills. In consultation with OCHCA and in accordance with OCHCA regulations, affected areas shall be identified and posted as being contaminated with sewage.

Signage shall be posted in locations so as to maximize public visibility and minimize the potential for public contact with contaminated areas. Signs shall be posted along all routes the public may be reasonably expected use to enter the contaminated area.

Signs shall remain posted for a minimum of five days, unless the Utilities Division is otherwise directed by the OCHCA.

4.7 Spill Termination
Once spill containment is assured, response crews shall focus on eliminating the source or cause of the spill and terminating the spillage.

Gravity Sewer Main Breaks. For spills caused by breaks or failures of gravity sewer mains, the Onsite Supervisor shall determine the location and nature of the sewer main break, and identify equipment and resources required to repair the break. After sewage diversion actions are implemented, excavation equipment shall be called in to expose the break and allow the Onsite Supervisor to determine the appropriate measures for repairing the break. Minor breaks may be resolved with sleeves, patches, or fittings, while major breaks may require replacement of pipe sections.

The Onsite Supervisor shall assess whether the spill or potential repair actions associated with the spill may affect nearby water or stormwater conveyance facilities. The Onsite Supervisor shall coordinate with applicable water or stormwater conveyance operators in making this determination and assessing whether (and how many) water system or stormwater staff are required as part of the spill response effort.

Gravity Sewer Main Blockages. For spills caused by sewer main blockage, the Onsite Supervisor shall determine the location and nature of the sewer main blockage, and identify equipment and resources required to clear the blockage. Once the nature of the blockage is identified, blockages may be removed by a variety of strategies including:
• Sewer main water jetting.
• Application of degreasers.
• Vactor truck pumping.

City of San Clemente Chapter 4
Utilities Division Spill Response Actions
Spill Emergency Response Plan Page 4 - 7 May 2023
• Sewer main rodding.
• Manual removal.

Gravity Sewer Main Surcharging. For spills caused by gravity main surcharging, the Onsite Supervisor shall determine the nature and cause of the temporary surcharging, and direct actions to (1) temporarily divert wastewater flows, and (2) eliminate the cause of the surcharging. Activities required to eliminate the surcharging may include:
• Restoring manhole covers removed by citizens or by force of flow. • Installing temporary dikes or dams to protect facilities from runoff or standing water.

If the sewer system surcharging is caused by inflows of stormwater from flooded streets due to improperly operating storm drains, it may be necessary to eliminate the street flooding by unblocking or cleaning the storm drains to allow storm runoff to flow into the storm drains instead of flowing into the sanitary sewer system.

Pressure Main Ruptures. For spills caused by breaks of failures in pressure mains, the Onsite Supervisor shall determine the location and nature of the break/failure, and identify equipment and resources required to (1) divert flows around the rupture and (2) repair the break. After sewage diversion actions are implemented, excavation equipment shall be called in to expose the rupture and allow the Onsite Supervisor to determine the appropriate measures for repairing the break. Minor ruptures may be resolved with sleeves, patches, or fittings, while major breaks may require replacement of pipe sections.

The Onsite Supervisor shall assess whether the spill, potential repair actions, or erosion effects associated with the pressure main spill may affect nearby water or stormwater conveyance facilities. The Onsite Supervisor shall coordinate with applicable water or stormwater conveyance operators in making this determination and assessing whether (and how many) water system or stormwater staff are required as part of the spill response effort.

Pump Station Pump/Motor/Control Failure. For spills caused by pump station failure, the Onsite Supervisor shall determine the nature of the pump, motor, or control failure, and identify equipment and resources necessary to restore pump station operations. For use in the pump or motor repairs, an inventory of spare pump parts, motor bearings, and electrical controls are available at the Utilities Division the SCWRP site.

If automatic controls fail, Utilities Division staff are to revert to manual operation of pumps until the automatic controls are repaired or restored. If required, the Utilities Division maintains portable pumps and diversion equipment for use until full pump station operations are resumed.

Pump Station Electrical Failure. For spills related to electrical failures, the Onsite Supervisor shall determine the nature and cause of the failure of onsite emergency generators to actuate upon power grid failure, and take actions to restore pump station power. Power restoration response actions shall include:
• Attempt to manually start onsite emergency generators. • Order mobile generators to the site.

City of San Clemente Chapter 4
Utilities Division Spill Response Actions
Spill Emergency Response Plan Page 4 - 8 May 2023
• If onsite emergency generators cannot be manually started, hook up the mobile generators and restore power.
• Determine if onsite repair of the emergency generators or generator controls is possible. • Maintain mobile generators at the site (even after grid power is restored) until the source of problems for the onsite emergency generators is diagnosed and corrected.

Pump Station Surcharging. For spills caused by pump station surcharging, the Onsite Supervisor shall determine the nature and cause of the temporary surcharging, and direct actions to eliminate the cause of the surcharging. Activities required to eliminate the surcharging may include:
• Restoring manhole covers removed by citizens or by force of flow. • Installing temporary dikes or dams to protect facilities from runoff or standing water.

If the pump station surcharging is caused by inflows of stormwater into the sanitary sewer system from flooded streets due to improperly operating storm drains, it may be necessary to eliminate the street flooding by unblocking or cleaning the storm drains to allow storm runoff to flow into the storm drains instead of flowing into the sanitary sewer system.

4.8 Assessment, Cleanup and Restoration
Monitoring. For spills in excess of 50,000 gallons that reach surface water, SWRCB Order No.

WQ 2022-0103-DWQ requires daily receiving water monitoring during each day of the spill for ammonia, total coliform, fecal coliform, E. Coli and enterococcus. Daily receiving water quality monitoring is required at the following locations:
• DSC-001, the point in a drainage conveyance system before the drainage conveyance system discharges into a surface receiving water (representative of the spill quality itself). • RSW-001, the point in the receiving water where the spill initially enters the receiving water. • RSW-001U, a point in the receiving water upstream from the point where the spill enters surface waters (e.g., characterizing unimpacted upstream receiving water conditions). • RSW-001D, a point in the receiving water downstream from the point of discharge where the spill is fully mixed with the receiving water.

Additionally, if warranted after consultation with OCHCA and onsite Utilities Division environmental specialists, the Onsite Supervisor shall direct Utilities Division staff to collect bacteriological water quality samples at additional sites to assess possible impacts to public health and the environment. Samples shall be labeled to show the collection date, time, and site.

The Utilities Operations Supervisor - Wastewater is responsible for (1) developing and implementing protocols for water quality monitoring, (2) determining where monitoring may not be possible as a result of safety concerns or access restrictions, (3) ensuring that monitoring instruments and devices are properly maintained and calibrated, and (4) maintaining records that document instrument maintenance and calibration.

Collection of Photographic/Video Evidence. Where possible and appropriate during and after spill response activities, the Onsite Director shall direct that photographic or video evidence be collected to City of San Clemente Chapter 4
Utilities Division Spill Response Actions
Spill Emergency Response Plan Page 4 - 9 May 2023
document (1) City response actions, (2) spill causes, (3) impacts to public health or the environment, and (4) cleanup and restoration measures. Photographic or video evidence shall be labeled to show the date, location, time, and person recording the event.

Site Cleanup and Restoration. After spill control is achieved, City response crews shall endeavor to return all spilled sewage to the sewer system (or as much as possible) and return the spill site to pre-spill conditions. Site cleanup operations shall be directed by the Onsite Supervisor, in consultation with OCHCA. The City currently maintains a “Hazardous Waste Response, Clean-up, Removal, and Disposal Environmental On-call Contract” for use in safely removing and cleaning chemical & biologically hazardous material such as chemicals spills, or blood and tissue clean-up from accidents.

Where appropriate, Vactor trucks or portable pumps shall be used to recapture spilled sewage and return it to the sewer system. Affected pavements, hardscapes shall be flushed with water, with flush water being recaptured and returned to the sewer system. Affected areas are to be assessed for impact to public health, biological resources, and other beneficial uses. Spill containment measures (barriers, dike, or dams) are not to be removed until the entire site clean-up is complete.

As part of this cleanup effort, City staff will (if storm drains are involved) coordinate with storm drain staff to ensure protection and integrity of storm water collection facilities. Additionally, if potable water conveyance facilities are near the spill site, City wastewater staff will coordinate with water system staff to ensure that repair or cleanup efforts do not endanger or adversely impact potable water conveyance facilities.

4.9 Reporting and Follow-Up Actions
Corrective Actions and Mitigation. After site cleanup, the Onsite Supervisor shall determine if any short-term corrective or mitigating measures are required to prevent spill recurrence. Short-term corrective measures may include:
• Temporarily stationing Utilities Division personnel at the site to monitor conditions and/or equipment after the spill is terminated.
• Stationing response equipment at the site until it can be confirmed that the spill threat is no longer present.
• Ordering additional immediate repair activities to strengthen the integrity of the wastewater collection system.
• Implementing special short-term video inspection of collection mains.

The Onsite Supervisor, in consultation with the Assistant Utilities Manager or the Utilities Operations Supervisor - Wastewater, shall also determine if any long-term corrective measures are required. Longterm measures may include:
• Increased frequency of video inspection of suspect pipe sections. • Replacing suspect pipe sections.
• Replacing or repairing suspect equipment.
• Acquiring additional spill response equipment.
