Item 15.
Coachella Sanitary District Sewer System Management Plan Page 14 4 Operation and
Maintenance Program
This chapter describes the District’s ability to properly manage, operate, and maintain all parts of the sanitary sewer system owned and operated by the District, and that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities.
Requirements:
D.4. OPERATION AND MAINTENANCE PROGRAM: The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.
4.1. Updated Map of Sanitary Sewer System: An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries.
4.2. Preventive Operation and Maintenance Activities: A scheduling system and a data collection system for preventive operation and maintenance activities conducted by staff and contractors.
The scheduling system must include:
• Inspection and maintenance activities;
• Higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems;
• Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes. The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.
4.3. Training: In-house and external training provided on a regular basis for sanitary sewer system operations and maintenance staff and contractors. The training must cover:
• The requirements of the General Order;
• The Enrollee’s Spill Emergency Response Plan procedures and practice drills; • Skilled estimation of spill volume for field operators; and • Electronic CIWQS reporting procedures for staff submitting data.
4.4. Equipment Inventory: An inventory of sewer system equipment, including the identification of critical replacement and spare parts.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 15
4.1 Updated Map of Sanitary Sewer System
The District maintains a comprehensive, customized, electronic based Geographic Information System (GIS) map of its sewer collection system, showing all pipeline segments and manholes within the District’s jurisdictional boundary. While Fieldforce has been the primary platform for GIS mapping, the District is preparing to transition to a new system. The sewer system database is regularly updated, and the District works with Akel Engineering under an on-call contract to keep its sewer hydraulic model current. This includes adding new assets as the City of Coachella approves new projects.
The District’s maintenance crew currently uses Fieldforce to access sewer line information and document activities, such as repairs, cleaning, and work order history. The system also provides mobile alerts when maintenance tasks are due and includes details on the required tools for each task. The District is transitioning to iWorQ software, which is expected to offer the same core functionalities as Fieldforce.
As part of the reissued Wastewater Discharge Requirements (WDR), agencies must collaborate with stormwater agencies to coordinate emergency spill responses. This ensures access to stormwater systems during spill events and prevents unintentional cross connections. To facilitate this, District staff need to know the locations of these facilities. Therefore, the District must maintain accurate, up-to-date maps of these systems within the sewer service area boundaries. Currently, the City’s Public Works Department -- responsible for maintaining the stormwater conveyance system -- does not have the storm drain infrastructure digitized in a GIS database. Instead, stormwater system information is available through record drawings for individual tracts. The District is awaiting the digitization of these as-built drawings in order to create a comprehensive map including both the sewer and stormwater systems. Until this digitization is completed, District sewer staff will continue to access individual tract records provided by the Public Works Department as needed. Once the comprehensive map is created, it will significantly enhance the efficiency and effectiveness of the District’s spill response efforts.
The District will provide State and Regional Water Board staff with access to the map(s) through submitting the sewer geodatabase to the State and Regional Water Boards as well as including the map within this SSMP Update, which will be submitted to CIWQS once a year. An updated map of the sewer collection system is included in Appendix F.
4.2 Preventive Operation and Maintenance Activities
The District currently performs in-house preventive operation and maintenance activities. This includes periodic cleaning, regular inspection of pump stations, and investigation of customer complaints.
4.2.1 Sewer Cleaning & CCTV Inspection
The District’s crew consists of seven operators who are responsible for sewer line cleaning, general maintenance, and treatment plant operations. To reduce the risk of blockages and spills, the District has implemented a hyrdrojetting plan designed to clean the entire system every five years. The District formally tracks sanitary sewer system sections subject to blockages and cleans each segment on a quarterly basis. All maintenance activities, including cleaning and CCTV inspections, are electronically documented using the iWorq system.
Although District staff are trained in CCTV inspection, the District primarily relies on its contractor, CV Pipeline, to perform all CCTV inspections. Currently, inspections are conducted on an as-needed basis rather than on a regular schedule. When issues are identified, CV Pipeline documents the defects and notifies the Collection System Lead.
The Lead reviews all inspection footage and provides repair or rehabilitation recommendations to the
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 16 Superintendent. For urgent situations requiring emergency rehab, the District employs various subcontractors to perform necessary work.
To implement a regular CCTV inspection schedule and meet its broader maintenance goals, the District must increase its staffing levels. This need was highlighted in a 2023 manpower study, which found that the current team of seven operators is insufficient. According to the study, the District requires four additional staff members to effectively carry out its maintenance program. In response, the District is actively planning to expand its workforce to close this staffing gap. To meet this goal, the District also plans to acquire CCTV equipment to increase in-house inspection capacity, while continuing to contract out additional CCTV inspection work as needed. Once the staffing and equipment need are met, the District plans to implement a regular CCTV schedule reaching their goal to CCTV inspect the entire system every (5) to seven (7) years (or approximately 14-20% a year).
4.2.2 Lift Station Maintenance
The District maintains its own lift stations. The operators at the District inspect the lift stations five times a week and use Everon Security Systems to monitor security of their lift stations. This security system alerts the District of an emergency and the need for backup generators or pumps. All District employees that are on standby respond to lift station emergencies and have authority to call other employees for additional support. In the case that this support is insufficient, the District uses a subcontractor to respond to the emergency.
4.2.3 Odor Control
The District receives approximately 3 to 5 isolated odor complaints annually, which are investigated and resolved.
Odor control is treated with the same urgency and safety considerations as a spill response. The following steps are taken to address odor issues:
1. Document the date, time, location and details of the complaint.
2. Investigate nearby manholes for blockages or issues with grease interceptors.
3. Identify the precise source of the odor.
4. Notify the Environmental Compliance Inspector, responsible for restaurant inspections, to assess whether the issue is recurring.
5. Contact the CCTV contractor if further inspection is needed.
6. Deploy a hydrojetting truck to clean the affected sewer line, if necessary.
7. Apply degreasers to the sewer line if the odor persists, to help break down grease and eliminate odors.
4.2.4 Corrosion Control
To prevent corrosion, the District uses CCTV inspections to locate any potentially corroded pipes. If corrosion is found, the District uses their contactor to replace or reline any corroded pipes.
4.2.5 Investigation of Customer Complaints
The District promptly addresses customer complaints about the sewer system. The collection system staff responds immediately by conducting CCTV inspections of the lines and making necessary repairs to the affected sections or manholes. This response involves assessing the complaint and resolving the issue efficiently.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 17
4.2.6 Data Collection
District staff document their cleanings and CCTV inspections electronically, filing them on in the District’s Fieldforce database, which is anticipated to be replaced with an iWorQ software. The District will continue to document and monitor system deficiencies with recurring issues identified through complaints, field inspections, and CCTV inspection results.
4.3 Training
The District has encouraged staff to participate in a continuing education program to meet the demands of maintaining the sewer system. This program offers scheduled in-house trainings, as well as regional training seminars conducted by California Water Environment Association (CWEA). These trainings cover Spill Emergency Response Plan procedures and practice drills and skilled estimation of spill volume for field operators. The District staff also attend trainings throughout the year held by Haaker, MME, Plumber Depot, and Tristate. The staff receive certificates for these trainings. Six (6) of the District’s operation staff are Certified State Wastewater Operators, ranging from Grade I-V. The District plans on performing annual trainings on the SSMP.
4.4 Equipment Inventory
The District is responsible for ensuring that their equipment is kept in proper working condition and that backup supplies are available. The District has backup generators and backup pumps at each lift station site in the case of a power outage.
District staff conduct inventory and inspections on a monthly basis. The District has a designated collection room with spare pipe and spare parts for emergency use. District staff maintain a folder to track current inventory of spare parts and usage. Sewer trucks are also regularly checked.
The District contracts CV Pipeline for CCTV inspection and several other contractors for pipeline repair. All subcontractors are responsible for managing their own equipment inventory.

6.2 Known Collection System Problems
The following are currently known collection system problems within the District’s system:
1. Capacity: The 2015 Sewer Master Plan found sewer system capacity deficiencies.
6.3 Causes of Sewer Spills
The District's sewer system spills were primarily caused by a storm event and debris, rather than common sources such as root intrusion or fats, oils, and grease (FOG).
6.4 Preventative Maintenance
Refer to Section 4.2 of this SSMP for the District’s preventative maintenance program.
6.5 Overflow Detection
The District employs multiple methods to detect spills:
1. Public Reporting: When a member of the public reports a spill, all relevant information is documented, including the date, time, estimated volume, and location of the incident. The District’s on-call standby operator is immediately dispatched to assess the situation. If necessary, additional operators are deployed to assist. The public reports spills through an emergency phone number, which connects to an operator who relays the information to the standby Collection Operator.
2. Automated Monitoring System: All lift stations within the District service area are equipped with level sensors – such as float balls, sonar or air sensors – to monitor water levels. If levels exceed normal thresholds, the District’s SCADA system automatically alerts an operator.
3. Field Observation: District staff or contractors discover spills during routine field inspections. Any such findings are immediately reported to the Sanitary Superintendent or Utilities Director. Operators
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 21 maintain constant communication throughout the day to ensure rapid response. All spill reports are investigated promptly and without delay upon notification.
Pre-planned coordination with the City of Coachella’s Public Works Department will be implemented before, during, and after a spill event to prevent or mitigate contamination of the stormwater system.
6.6 Initial Spill Response
6.6.1 Site Assessment
District staff shall investigate and assess the site conditions where the spill occurred using the following methods:
1. Immediately start a record of the date, time, location, and duration of the spill.
2. Determine the size and extent of the spill.
3. Determine the Category of the spill. (Refer to Section 6.9, Spill Categories)
4. Assess manpower and equipment needed to correct the spill.
5. Determine any potential hazards, such as vehicle and pedestrian traffic.
6. Identify receiving water that may be impacted by spill.
7. Implement traffic control measures as needed.
8. Post warning signs and block contaminated areas with yellow caution tape and/or barricades if spill poses a public threat or it has or will reach Waters of the State.
9. In the event of two simultaneous spills, management will call contractors as backup emergency services.
6.6.2 Containment Procedures
Containment of the spill is the top priority. District staff handle spill calls and containment and contact contractors for general sewer system repair. If additional help is needed, the District’s other contractors provide support with pumping, bypassing, traffic control, spill clean-up, equipment rentals, and generator repair.

The District’s staff prioritize containing spills within the smallest possible area, with a focus on protecting surface water. When practical, they will direct the spill to remain in the street, avoiding entry into storm drains and other water bodies. The following methods will be used to ensure thorough containment:
1. Immediately contain the spill by constructing a temporary berm, if applicable.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 22
2. Isolate, contain, or divert wastewater flow from open channels and storm drains using sandbags, inflatable dams, or soil barriers. Use absorbent materials to prevent further spread.
3. Protect storm drains by blocking openings or diverting flow with sandbags, prioritizing containment within the street. Block all downstream and upstream inlets.
4. Implement traffic control per the District's plan:
a. Know the surroundings and work area location for the safety of the operators and the public. b. Obtain authorization from the appropriate jurisdiction to set up traffic controls. c. Set up the five areas of the traffic control zone: Advance warning, transition, buffer, work, and termination. d. Provide advance warning to motorists and pedestrians. e. Safely route traffic around work areas.
f. Protect workers with vehicles when possible.
g. Use lighted warnings for night work.
h. Isolate the spill area.
5. Should the spill take place in an area not normally accessible to the public (i.e. field, etc.) the crew will use any reasonable means to pool the flow in that area for recovery.
6. Capture the spill:
i. Berm the flow and pump into the nearest clear, flowing manhole, if needed. ii. Contact the Legally Responsible Official (LRO).
iii. Evaluate spill volume using established methods.
7. Determine the spill's source and cause (e.g., debris type, storm event). Inspect downstream manholes for potential blockages.
8. Remove obstructions and restore flow:
i. Restore flow using hydro jetting, rodding, excavation, or other methods. ii. If needed, position a hydro jetter downstream and jet upstream from a clear manhole. iii. Capture all debris.
iv. Request additional staff and equipment for unresolved blockages. v. If still unable to clear the blockage, request immediate assistance with the mobilization of bypass pumping and CCTV support to determine the problem.
vi. Contact District's on-call contractor for pipe repairs. vii. Ensure downstream manholes are clear and flowing.
9. All sewage shall be captured and discharged into the closest clear and flowing manhole. Any contaminated materials unfit for the sewer and likely to cause blockages shall be transported to a local landfill for ultimate disposal. See Section 6.8 for treatment in dry or wet weather conditions and collection instructions.
10. Estimate spill volume as detailed in Section 6.13.2.
11. Notify relevant regulatory agencies per Section 6.10.
12. Safely perform required spill sampling detailed in Section 6.20.
6.6.3 Sewer Bypassing

1. Post warning signs at the site for the public to stay out of the area and block contaminated areas with yellow caution tape and/or barricades if the spill poses a public threat or it has or will reach waters of the State.
2. Use traffic cones, barricades, or warning tape to limit pedestrian and vehicle traffic access to affected areas.
3. In the event of a spill discharging into surface or state waters, closures must be implemented 100 feet upstream and downstream from the spill site, unless alternative instructions are provided by regulatory agencies. Signage must be posted at the discharge point and both upstream and downstream locations.
4. Warning signs and other public notices shall remain in effect until there is no further risk to public health and the environment.
6.8 Recovery and Clean-Up (Mitigation)
1. If the spill occurs during dry weather conditions:
Secure the Spill Site: Restrict public access to the spill area until cleanup is complete.
Solid Waste Removal: After containing the spill, use manual tools (rakes, brooms, etc.) to collect and properly dispose of all solid debris.
Wastewater Removal: Vacuum any remaining standing wastewater and discharge it into a flowing, unobstructed manhole.
Contaminated Soil Remediation:
i. Vacuum any free-standing wastewater from contaminated soil. ii. Apply absorbent product and allow it to dry.
iii. Remove contaminated soil (as necessary) with shovels or front-end loader. iv. Transport the contaminated soil to an approved landfill for disposal.
Contaminated Structure Disinfection:
i. Disinfect contaminated structures (streets, sidewalks, buildings, etc.) by pressure spraying with a 25- ppm sodium hypochlorite solution (liquid bleach).
ii. Allow a 1-hour contact time for disinfection.
iii. Rinse the disinfected structures with water.
iv. Vacuum the wash water and dispose of it into a flowing, unobstructed manhole. v. Important Considerations:
1. Prior to pressure washing, remove all contaminated materials and soil, and block catch basins. Ensure a vacuum truck is ready to collect the wash water.
2. Prevent any water, wastewater, bleach, or containment materials from entering the storm drain system.
3. Avoid using bleach in heavily populated areas or within 100 feet of surface water or storm drain inlets. Consider less hazardous alternatives for surface disinfection.
4. Document the team's standard sidewalk/structure cleaning procedure.

6.9 Spill Categories
Per the Reissued WDR, there are now four (4) categories of spills. Individual spill notification, monitoring and reporting must be in accordance with the following spill categories:
6.9.1 Category 1 Spill
A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under this General Order that results in a discharge to:
• A surface water, including a surface water body that contains no flow or volume of water; or
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 27 • A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly.
Note: Any spill volume not recovered from a drainage conveyance system is considered a discharge to surface water, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility.
A spill from a City-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the City will report all Category 1 spills per Appendix H of this document.
6.9.2 Category 2 Spill
A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water.
A spill of 1,000 gallons or greater that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 2 spill.

6.20 Sanitary Sewer Spill Water Quality Monitoring Plan This Sanitary Sewer Spill Water Quality Monitoring Plan will be implemented immediately upon discovery of any Category 1 spill of 50,000 gallons or more to assess potential impacts on surface waters.
Recent updates to the waste discharge requirements general order for sanitary sewer systems (WDR) require timely implementation of spill-specific notification, monitoring, and reporting tasks for spill events that exceed certain volume thresholds. In the event of a spill >50,000 gallons, the WDR outlines monitoring requirements generally aligned to estimate spill location and spread as well as receiving water conditions to support impact analysis documented in a spill report. This Monitoring Plan provides technical and procedural details to allow for rapid implementation of water quality monitoring activities that may be used to characterize the extent and magnitude of potential impacts related to a spill. These water quality activities are based on standard procedures implemented as part of municipal and industrial water quality monitoring programs.
6.20.1 Sample Collection Timing
Water quality sampling must be conducted no later than 18 hours after discharger’s knowledge of a potential discharge to a surface water.
Daily samples must be collected at the discharge point of the receiving water and at locations upstream and downstream of the discharge point. If the spill entered the receiving water from a drainage conveyance system, a sample must also be taken from the conveyance system. Upstream samples should be taken at a sufficient distance from the discharge point to capture ambient conditions absent of spill material. Downstream sample point must be taken far enough from the discharge point where the spill material is fully mixed with the receiving water.
Sampling will not be conducted if there are access restrictions or any concerns regarding field staff safety. These concerns may include heavy rain events, which compromise access points through flooding and swift currents.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 37 Thunderstorms will also be avoided when lightning occurs. Sampling will only be conducted if there are at least two members of the field staff team available. Provide documentation of access restrictions and/or safety hazards in the corresponding required report.
Once collected, the samples must be submitted to a certified laboratory for analysis of ammonia and fecal indicator bacteria per Section 6.20.4.1 in a timely manner.
6.20.2 Monitoring Equipment
The use of proper monitoring equipment is necessary to ensure the safety of personnel collecting the samples and integrity of the samples themselves. Contact with raw sewage can have acute and long-term impacts to human health that can be avoided using the proper personal protective equipment (PPE). Additionally, contamination of the sample may occur if inappropriate equipment or handling methods are used.
Recommended PPE for receiving water monitoring includes:
• Disposable latex gloves
• Close-toed shoes, long pants, and long sleeve shirt
• Optional Tyvek suit or similar if contact with the spill material is likely • Eye protection (glasses or goggles) and/or face shield • Disinfecting wipes and hand sanitizer
To be ready for a spill, it is recommended the following list of equipment is procured and stored in a centralized location. Store enough sampling bottles to be able to collect up to four days of samples at each of the four monitoring location types described in Section 2.4. In the event that any of the bottles are lost or compromised, it is recommended to also have a full set of backup bottles. • Four days’ worth of sample bottles plus one days’ worth of back-up includes:
o 40 100 mL plastic bottles with Sodium thiosulfate preservative o 20 250 mL plastic bottles with Sulfuric acid preservative • Sample bottle labels and water-resistant marker
• CoC sheets
• Visual observation log
• Cooler for ice to keep samples at or below 4°C
• Grab pole to safely reach into drains as needed
6.20.3 Monitoring Locations
Within the context of the District’s geography and sewer system assets, the District shall identify potential spill monitoring locations. The monitoring locations shall be selected to provide core representation of locations where critical sewer infrastructure has potential for a large spill event, adjacent stormwater conveyance and other
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 38 infrastructure has potential to be impacted by a large spill event, and during/post-event monitoring at the selected locations may provide reasonable capacity to characterize impacts to water quality from a spill. A spill that impacts water quality is likely to be conveyed through the MS4 before reaching the receiving water, however, in limited situations a spill immediately adjacent to a receiving water may discharge directly to the water body. The WDR defines four distinct monitoring location types (Figure 6.1):
• Flow in MS4 or non-sewer infrastructure conveyance(s) prior to the discharge point • Receiving Surface Water (RSW) discharge point
• RSW upstream of the discharge point
• RSW downstream of the discharge point
A spill event will determine the exact monitoring location(s) needed to be sampled based on discharge point to the receiving water. However, the guidelines for identifying core monitoring locations and methods documented in this Monitoring Plan allow for rapid implementation of a monitoring program that will both meet the requirements of the WDR and provide critical information that may be used to inform the required Spill Technical Report impact analysis.
Accordingly, this Monitoring Plan only provides guidance on identifying potential upstream and downstream monitoring locations. Monitoring in the MS4 or non-sewer infrastructure conveyance(s) as well as RSW discharge point monitoring will require the District to evaluate on a spill-by-spill basis where to set up these locations.

6.20.4 Water Quality Sample Constituents
Attachment E of the WDRs list two required constituents to monitor in surface water impacted by a sewer spill. All water quality samples are required to measure the concentration of ammonia and the concentration of the appropriate bacterial indicator(s) per the applicable Basin Plan water quality objectives. Table 6.10 identifies the required constituents to sample for and information on the specific requirements for each sample method.

6.20.5 Sample Collection Methods
Sample collection methods will vary depending on the surface water and the safety of the Field Staff. The following instructions should be taken into consideration by Field Staff:
• Collect all samples against the direction of the water flow (face upstream) • Collect upstream sample first
• Collect samples well away from the bank (preferably where water is visibly flowing) and 6” below the surface • Avoid sampling debris or scum layer from the surface
• Avoid disturbing sediment from the streambed, and do not include it in the sample bottle • Photograph evidence of water quality impacts (debris, dead fish, etc.) • Remove the sample bottle cap immediately before collecting each sample • Do not allow the inside of the sample bottle cap to touch anything • Clean, powder-free, nitrile gloves will be worn for all bottle handling • Samples should be placed on ice immediately after the sample is collected The direct fill sample collection method, per Section 6.20.6.1, is the preferred sampling method since it does not use an intermediate container. In cases where the direct fill method cannot be used due to accessibility or safety, an intermediate bottle and a grab pole can be used, per Section 6.20.6.2.
6.20.5.1 Direct Fill Sample Collection
The direct fill sample collection method will be used in cases where the surface water can be entered safely by the Field Staff. Field Staff will wear waders and ensure that the water level and velocity of the surface water are low enough to provide a safe entry and sampling environment.
Sample bottles will be filled by direct submersion to approximately mid-depth as follows.
Wade to approximately the area of the water body with the highest flow rate and face upstream. This will most likely be midstream but can be in a different portion of the stream, depending on the hydrology.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 40 Submerge the sample bottle with its cap on to approximately mid-depth at a location of significant flow (avoid stagnant water). Hold the bottle upright under the surface while it is still capped.
Open the lid carefully just a little to let the water run in. Fill the bottle and staff the cap tightly while the bottle is still underneath the surface.
Remove the bottle from the stream and place it on ice.
6.20.5.2 Intermediate Container Sample Collection
If the flow, water level and/or access point are deemed unsafe, then an intermediate bottle attached to a grab pole will be used for sample collection. A clean, new intermediate bottle will be used for each sampling event and sampling site.
Ammonia and bacteriological sample bottles will be filled with intermediate container sample collection as follows:
Attach the intermediate bottle to an expandable pole using tape or cable ties and remove the lid.
Submerge the intermediate bottle, attached to an expandable pole, to approximately mid-depth at a location of significant flow (avoid stagnant water).
Remove bottle from water and empty contents downstream. Repeat this twice more, for a total of three rinses.
Once the intermediate bottle is properly rinsed, return it to approximately mid-depth at a location of significant flow (avoid stagnant water).
Using the intermediate bottle, fill the bacteriological sample container and then the ammonia bottle. Ensure that the bottle does not overflow and that the preservative stays in the sample container.
After the bottle is filled, replace the bottle lid, and place it on ice.
6.20.6 Sample Handling and Custody
The Field Staff will ensure that all samples are collected and submitted to the Babcock Labs as soon as possible, but no later than the maximum hold times listed in Table 6.10. If timing or logistics prevents a hold time being met, the Field Staff will contact the LRO or their designee.
6.20.6.1 Sample Bottle Labels
The Field Staff will fill out the labels on all sample bottles with a waterproof pen, which will contain the sample collection date and time, analyte, analysis method, station number and name, and Field Staff names. The station identification protocols are below.

• Sample container type
• Comments/special instructions
• Samples relinquished by (signature, print name, date)
6.20.7 Site Access and Safety Considerations
Access to monitoring locations must be assessed for safety considerations during each visit. Field staff should use caution at all times in evaluating roadway safety and right of way conditions. Specific safety concerns relating to surface water sampling includes potential slip, trip, and fall hazards, biological hazards, and swift water. To reduce safety risks, grab poles should be considered for sample collection at difficult to reach monitoring locations.
Unlike receiving water monitoring locations, drainage conveyance monitoring locations are often located in the street and require some level of traffic control based on the type of road and time of day. Compounding this issue is that spills frequently occur during rain events which make for even more dangerous road conditions. At all times, personnel safety should be the top priority, and monitoring should be delayed or relocated if safety is potentially compromised.
6.20.8 Reporting
Electronic reporting to the California Integrated Water Quality System (CIWQS) is required for all spills. For spills greater than 50,000 gallons and discharged to receiving waters, a Spill Technical Report is required within 45 days of the spill end date. The Spill Technical Report must contain the following:
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 42 • Spill causes and circumstances
• Discharger’s response to spill
• Water quality monitoring information
• Evaluation of spill impacts, including short- and long-term impact(s) to beneficial uses of surface waters Spill report information is then used by Regional Water Quality Control Board staff to evaluate the relative impact to the environment and to form the basis of potential spill-specific enforcement actions.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 43 7 Sewer Pipe Blockage
Control Program
This chapter discusses the District’s sewer pipe blockage control measures, including identification of problem areas, focused cleaning, and source control.
Requirements:
D.7. SEWER PIPE BLOCKAGE CONTROL PROGRAM: The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed. The procedures must include, at minimum:
• An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe-blocking substances;
• A plan and schedule for the disposal of pipe-blocking substances generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of substances generated within a sanitary sewer system service area; • The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, recordkeeping and reporting requirements;
• Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance; • An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and • Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.
The District does implement a Sewer Pipe Blockage Control Program despite the fact that fats, oils, grease (FOG), rags, and debris have not been identified as a significant source of blockages. In the past three years, only one (1) spill was attributed to debris. The District’s maintenance crew targets and cleans the Preventative Maintenance Areas on a quarterly basis, with some areas cleaned monthly.
Annual inspections of food service establishments (FSEs) are conducted by the District’s Environmental Special Programs Manager, with all inspections and violations regularly documented. Each new business must undergo a project submittal process to assess their FOG production potential. New restaurants are required to install a grease interceptor unless exempt based on their FOG production potential, which is determined through the Wastewater Discharge Survey that all new businesses must complete. Businesses that do not need a grease interceptor receive a waiver.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 44 If the sewer maintenance staff detects a FOG issue originating from a restaurant, the Environmental Special Programs Manager is notified to investigate and identify the source. Once confirmed, FOG Best Management Practices (BMP’s) are enforced, with regular follow-ups to ensure compliance.
Areas identified as prone to FOG production are placed on a regular cleaning schedule. These Preventative Maintenance Areas are cleaned quarterly, or monthly, depending on the severity.
During annual routine inspections, the District’s Environmental Special Programs Manager distributes information and brochures to restaurants about the District’s FOG program and proper disposal methods for fats, oils, grease, rags, and debris. The Environmental Special Programs Manager also provides a list of grease hauling companies to the restaurants. The District is working on adding grease interceptor best management practices (BMPs) to the Environmental section of the District of Coachella’s website.
During the audit period, the District collaborated with Coachella Valley Water District to raise public awareness about reducing sewer system blockages through the CV Water Counts website (https://cvwatercounts.com/), which provides information on proper FOG disposal. Additionally, information on proper FOG disposal and grease interceptor BMPs is distributed to businesses during their annual inspections.
The District will be able to address sewer blockage prevention by using the new rates to fund additional staff.
Current staffing levels have been determined to be insufficient to meet the demands of maintaining the sewer system.
Chapter 13, Article III (Wastewater Pretreatment) of the City Municipal Code provides the legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages. Chapter 13, Article IV (Wastewater Pretreatment) also provides the legal authority for site inspections and enforcement of violations of wastewater discharge regulations.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 45 8 System Evaluation, Capacity
Assurance, and Capital Improvements
This chapter discusses the District’s capacity management measures, including the most recent Master Plan and recommended capacity improvement projects.
Requirements:
D.8. SYSTEM EVALUATION, CAPACITY ASSURANCE AND CAPITAL IMPROVEMENTS: The Plan must include procedures and activities for:
• Routine evaluation and assessment of system conditions; • Capacity assessment and design criteria;
• Prioritization of corrective actions; and
• A capital improvement plan.
8.1 System Evaluation and Condition Assessment: The Plan must include procedures to:
• Evaluate the sanitary sewer system assets utilizing the best practices and technologies available; • Identify and justify the amount (percentage) of its system for its condition to be assessed each year; • Prioritize the condition assessment of system areas that:
o Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;
o Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas;
o Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act section 303(d) List;
• Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods;
• Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State; • Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and
• Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions.
8.2. Capacity Assessment and Design Criteria: The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events;
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 46 • The appropriate design storm(s) or wet weather events that causes or contributes to spill events; • The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.
The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change;
• Increases of erosive forces in canyons and streams near underground and aboveground system components due to larger and/or higher-intensity storm events; • Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities.
8.3. Prioritization of Corrective Action: The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills.
8.4. Capital Improvement Plan: The capital improvement plan must include the following items:
• Project schedules including completion dates for all portions of the capital improvement program; • Internal and external project funding sources for each project; and • Joint coordination between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects; and Interagency coordination with other impacted utility agencies.
8.1 System Evaluation and Condition Assessment
The District’s last sewer system master plan was performed in 2015, which included a model of the collection system. Hydraulic simulations were performed for the present (2015) and future build out scenarios, identifying system deficiencies and recommending upgrades for deficient pipe segments.
Currently, the District performs CCTV inspections on an as-needed basis. Any issues identified during these inspections are tracked by the maintenance crew and reported to the Superintendent for immediate rehabilitation or replacement. The District regularly updates and maintains its hydraulic model. When new developments request to connect to the public system, the District conducts a capacity analysis and updates the model based on new connections. The District is currently finding it more efficient to perform ongoing hydraulic analyses rather than budgeting for a new master plan. There is no sewer master plan update scheduled at this time. In the past, the hydraulic model was only used during the master plan creation period and was not updated until the next master plan. The District now finds it beneficial to have ongoing efforts to identify areas of concern and address system deficiencies continuously.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 47 With the anticipated sewer rate increase, the additional funding will support increased staffing levels needed to carry out this work. Furthermore, the District will be able to enhance the frequency of CCTV inspections, enabling more consistent and proactive condition assessments of the sewer system.
8.2 Capacity Assessment and Design Criteria
The 2015 Master Plan included a capacity evaluation and identified capacity-related improvement projects for the collection system. The capacity assessment completed as part of the District’s Sewer Master Plan was based on hydraulic modeling of the District’s collection system under current (2015) and future design flows. Surcharged pipes were identified, and these pipe segments were recommended for upgrade.
The District has not experienced any sanitary sewer overflows due to hydraulic deficiencies in the sewer system in the past ten years. Likewise, modeling of the District’s sewer system conducted during the preparation of the 2015 Sewer Master Plan indicated no overflows were anticipated due to hydraulic deficiencies.
The District plans to regularly update its hydraulic model from the 2015 master plan to continuously evaluate the sewer system’s ability to convey existing and future peak flows. Additionally, this model will continue to identify areas with limited capacity and the need for system improvements and rehabilitation based on any capacity issues identified.
8.3 Prioritization of Corrective Action
Previously, the District assessed problem areas with recurring issues within the sewer system and ensured that they were cleaned regularly.
8.4 Capital Improvement Plan
The District has been implementing capital improvement projects in alignment with the 2015 Sewer Master Plan.
In addition to scheduled CIP projects, the District has been performing rehabilitation and replacement projects as issues arise.
To address deficiencies identified in the 2015 Sewer Master Plan, the District recently contracted Dudek to design targeted improvement projects. This includes a capacity upgrade along Tyler St between Avenue 53 and Avenue
54. Additionally, the District has been undertaking other sewer main extension projects.
Funding for rehabilitation and replacement projects is allocated based on system needs. As budget permits, the District prioritizes projects involving pipelines that have reached capacity, as identified in the 2015 Sewer Master Plan.
Item 15.
Coachella Sanitary District Sewer System Management Plan Page 48 9 Monitoring, Measurement and
Program Modifications
This section of the SSMP discusses parameters the District tracks to monitor the success of the SSMP and how the District plans to keep the SSMP current.
Requirements:
D.9. MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS: The Plan must include an Adaptive Management section that addresses Plan-implementation effectiveness and the steps for necessary Plan improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate Plan activities;
• Monitoring the implementation and measuring the effectiveness of each Plan Element; • Assessing the success of the preventive operation and maintenance activities; • Updating Plan procedures and activities, as appropriate, based on results of monitoring and performance evaluations; and
• Identifying and illustrating spill trends, including spill frequency, locations and estimated volumes.
In the past, the District did not have a formal process for tracking the success of SSMP elements. As issues arose and elements changed, the District tracked certain segments of each element of the SSMP such as organizational changes and system maintenance. Currently, the District is motivated to be proactive about spill prevention and understand how tracking their SSMP elements will improve efficacy of this goal.
The District will perform regular tracking of the SSMP elements and their effectiveness. The District will develop a database, or similar tool, to maintain specific information related to the SSMP, as a central repository for changes to the SSMP and regularly track the success of SSMP elements, including the preventative maintenance activities noted above. The District will evaluate whether SSMP elements have changed so that changes can be documented in a Change Log to include the specific change, the date of the change and the name of the person making the change. The Change Log is included in Appendix I. Procedures and activities will be updated based on the tracking and assessment methods described therein. Table 9-1 details a schedule for evaluating the Monitoring, Measurement, and Program Modifications.

The District will use the specific monitoring parameters listed in Table 9-2 and documented on the tracking sheet included in Appendix J to assist in completion of the annual SSMP Audit described in Plan Element 10, Internal Audits. The District will also continue to collect data for all performance measures currently tracked. This additional information that the District collects, such as customer complaints and length of pipe cleaned, will be used to support or further evaluate the success and limitations of the SSMP as needed.
The District has consistently tracked the components listed in Table 9-3 to quantitatively determine the effectiveness of preventive operation and maintenance activities. Using this data and comparing it to spill data shown in Table 9-4, the current preventative operation and maintenance activities appear to be successful in reducing spills. However, once the District increases staffing levels and establishes a regular CCTV inspection program, they are confident this will ensure spills are further minimized by reaching their goal to CCTV inspect the entire system every (5) to seven (7) years (or approximately 14-20% a year), as well as performing regular rehabilitation and replacement projects to rectify condition- and capacity-deficient pipelines and infrastructure.

Requirements:
D.10. INTERNAL AUDITS: The Plan shall include internal audit procedures, appropriate to the size and performance of the system, for the Enrollee to comply with section 5.4 (Sewer System Management Plan Audits) of the General Order.
The reissued State Water Resources Control Board’s Order Number WQ 2022-0103-DWQ requires that an agency conduct an internal audit of its SSMP at least once every three (3) years. The audit is to evaluate how the District has developed and implemented each of the eleven elements of the SSMP and how each element is functioning to assist in the prevention of sanitary sewer spills. The audit report shall be kept on file at the District offices and uploaded to the online California Integrated Water Quality System (CIWQS) database within 6 months after the end of the 3-year audit period. Any deficiencies found during the audit are addressed and corrected.
The due dates for the District’s SSMP and SSMP audits can be found here using the District’s WDID (7SSO10520):
https://www.waterboards.ca.gov/water_issues/programs/sso/lookup/ In 2025, the District contracted with Dudek to complete its audit and work closely with the District’s staff to review the SSMP, its implementation, and the effectiveness of the District’s efforts in reducing spills.
The District plans to complete audit requirements and due dates corresponding to the original audit cycle deadlines.
The District’s next SSMP audit is to be completed and uploaded to CIWQS by February 2, 2028. During this next audit, the District will:
• Evaluate the effectiveness of each SSMP element and identify areas of improvement. • Assess progress in implementing the SSMP and preventing sanitary sewer spills. • Review monitoring, measurement, and program modifications under Element 9. • Summarize system improvements completed in the previous year. • Outline planned system improvements for the upcoming year, including a proposed schedule.
Audit findings and recommendations will be incorporated into future SSMP Updates to ensure continuous improvement and regulatory compliance.
Item 15.

This section of the SSMP discusses the District’s communications with the public.
Requirements:
D.11. COMMUNICATION PROGRAM: The Plan must include the following items as appropriate and applicable to the Enrollee’s system:
The Plan must include procedures for the Enrollee to communicate with:
• The public for:
o Spills and discharges resulting in closures of public areas, or that enter a source of drinking water, and o The development, implementation, and update of its Plan, including opportunities for public input to Plan implementation and updates.
• Owners/operators of systems that connect into the Enrollee’s system, including satellite systems, for:
o System operation, maintenance, and capital improvement-related activities.
The District maintains its 2015 Sewer Master Plan Update on its website (https://www.coachella.org/departments/public-works-department/sanitation-division), for public review. While the District’s SSMP is not currently available online, it will be published on the website soon. Hardcopy versions of the SSMP are available at the Wastewater Treatment Plant and are also stored digitally on the District’s server.
The District intends to present the updated SSMP at a future Board meeting and incorporate opportunities for public input regarding any sewer system concerns following its publication online. Once approved by the District’s Board on September 10, 2025, the SSMP will be maintained on the Sanitation Division section of the District’s website.
The District utilizes the CV Water Counts website (https://cvwatercounts.com/) to educate the public on proper FOG disposal, spill notification, and other sewer system information. The District is considering adding a link to the CV Water Counts website on their own site to direct the public to more detailed information on FOG disposal and spill notification. The District also communicates to the public regarding spills and discharges using social media and its website.

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
4 1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures.
Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.
Sewage contains high levels of suspended solids, non-digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants.
For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State, and the environment.
This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance improvements; and
• Report noncompliance with this General Order per reporting requirements.

3. FINDINGS
3.1. Legal Authorities
3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160).
3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations.
A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(l)(1)).
Item 15.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
8 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to “require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region… or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires…In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports.” Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination.
The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports.
Water Code section 13383(a) authorizes the Water Boards to “establish monitoring, inspection, entry, reporting, and recordkeeping requirements… for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section
5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225(c) and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills

9 when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills.
3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general waste discharge requirements than individual waste discharge requirements.
Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system-specific design elements and system-specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements.
As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each Regional Water Board and take into account the environmental characteristics of sewer service areas and hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies.
3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003-DWQ also required system-specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length.
Item 15.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
10 To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to:
1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and
2. Implement a proactive approach to reduce spills.
The previous Order required Sewer System Management Plan elements for “the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ with Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills.
3.1.6. Existing Memorandum of Agreement with California Water Environment Association
The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association’s Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers.
On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Association - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations.
On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators.

11 3.2. General
3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States.
3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.
More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage.
Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET)
• Agricultural Supply (AGR)
• Estuarine Habitat (EST)

3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state.
There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].
A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to:
Item 15.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
13 o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events; o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.
3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses.
Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution.
Item 15.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
14 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste).
3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region-specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives. The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives.
3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings.
The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and (2) enhances the ability for Water Board enforcement of violations of the established prohibitions.
3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of
Item 15.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
15 Compliance While Maintaining Water Quality Protection. Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.
3.3.4. State Water Board Human Right to Water Resolution On February 16, 2016, the State Water Board adopted Resolution 2016-0010, titled Adopting the Human Right to Water as a Core Value and Directing its Implementation in Water Board Programs and Activities, addressing the human right to water as a core value and directing Water Board programs to implement requirements to support safe drinking water for all Californians.
On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.
This General Order supports the State Water Board priority in collecting a comprehensive set of data for California’s wastewater systems, including sanitary sewer systems. Data reported per the requirements of this Order will be used with data from other Water Boards’ programs, to further develop criteria and create a statewide risk

16 framework to prioritize critical funding and infrastructure investments for California’s most vulnerable populations, including disadvantaged or severely disadvantaged communities with inadequate or failing sanitation systems and threatened access to healthy drinking water supplies.
3.3.5. State Water Board Open Data Resolution
On July 10, 2018, the State Water Board adopted Resolution 2018-0032, titled Adopting Principles of Open Data as a Core Value and Directing Programs and Activities to Implement Strategic Actions to Improve Data Accessibility and Associated Innovation, directing regulatory programs to assure all monitoring and reporting requirements support the State Water Boards’ Open Data Initiative.
3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled Comprehensive Response to Climate Change, requiring a proactive response to climate change in all California Water Board actions, with the intent to embed climate change consideration into all programs and activities.
3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements that is exempt from the California Environmental Quality Act (Public Resources Code section 21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14, section 15301, to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in sections 15301 and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
3.5. State Water Board Funding Assistance for Compliance with Water Board Water Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation of the State Water Board financial assistance programs, per Board-adopted funding policies. Among other funding areas, the Division administers loan and grant funding for the planning and construction of wastewater and water recycling facilities per funding program-specific policies and guidelines. Applicants may apply for Clean Water State Revolving Fund low-interest loan, Small Community Wastewater grant funding assistance, and other funding available at the time of application, for some of the costs associated with complying with this General Order.
