Compliance is also included for Order No. 2013-0058-EXEC subsection D. 7 (v) of the State Waste Requirements for Sanitary Sewer Systems (SSS) and the Waste Discharges Requirements (WDRs). In cases where Category 1 spills of 50,000 gallons or greater are discharged to surface waters, the City must conduct water quality sampling of the receiving water within 18 hours of the initial knowledge of the spill and submit a Technical Report within 45 calendar days to the Board.
1.1 RESPONSIBILITIES
Field personnel are responsible for collecting samples in accordance with the Water Quality Monitoring Program (WQMP) procedures, and communicating to the Sewer and Storm Water Supervisor, Superintendent of Utilities, and Deputy Director of Public Works/Utilities Manager if any unexpected issues or conditions arise in the field that may cause a significant variation in the sample collection procedures. Samples shall not be collected until the issue(s) is/are resolved.
2.0 SAMPLE COLLECTION
A grab sample should be collected as soon as possible, or within 18 hours of the SSO.
All analysis will be performed on a rush basis (2-day rush) in order to identify possible water quality exceedances to allow for immediate notifications to the appropriate regulatory agencies.
2.1 REQUIRED SAMPLES
Collection of specific samples per Regional Board directives are as follows:
· Ammonia - Nitrogen
· Total Coliform
· Fecal Coliform
· E. Coli
· Enterococcus
2.2 NUMBER OF SAMPLES

2.4 SAMPLE CONTAINER AND PRESERVATION
All sample containers, preservation and holding times shall be based on the USEPA approved standard methods.
Always examine sample containers before sampling. If any of the caps are loose, or cracked, or any foreign particle is observed, discard the container and use a new sample container.
Each container should have a label with the Site Identification, Project, Analysis, Preservative, Date, Time, and Initials.
Constituent Container
Type Sample Volume Preservative Holding Time
Ammonia-Nitrogen Plastic 250 ml H2SO4 48 hours
Enterococcus
Sterile
plastic 125 ml None ASAP - 24 hrs. max

2.5 SAMPLING PROCEDURES
To preserve the integrity of the sampling process and ensure the sampling process is free from pollutants that could bias analytical results, containers that are pre-cleaned or sterilized and with preservatives, will be provided by the City’s contract laboratory (currently Weck Laboratories, Inc.).
· Gloves used during sampling can also be a source of contamination.
Sampler shall use new latex or nitrile gloves when collecting SSO samples.
· Grab samples shall be collected facing upstream. The sample shall be collected directly into the bottle provided and not touch the walls of the outfall.
· Container shall not be rinsed or overfilled. Doing so may wash out the preservatives in the bottle. If this happens, discard the container and take a new sample using a new container.
SOP SSO Sampling Procedures No.SSO01 Effective 4/21/2023
City of Downey Page 4
· Do not set the container cap down! Hold it with fingers away from edges and away from splashing water, and hold the lid in your hand so that the inside of the lid faces down.
· NEVER touch the inside of the cap or the container.
· As soon as the container is filled, remove from the flow, affix the cap on the container and check to make sure that your container is properly sealed, as the sample will leak if not properly closed.
2.6 FIELD TEST KITS
2.6.1 pH
pH concentrations should be measured in the field using the Hach Pocket Pro pH meter or Paper strips.
Hach Pocket Pro pH meter
Conditioning
· Condition, the Hach Pocket Pro pH tester with buffering solution 10, by immersing it in electrode storage solution or tap water for at least 30 minutes before use. Repeat with buffering solution 7 and 4 to ensure proper calibration. Use deionized water to clean probe. Or grab a Hach Pocket pro tester that has already been calibrated which will be much faster.
pH Measurement
· Press the on off button to switch the tester on.
· Dip the probe about 2 to 3 cm into sample. Stir and let the read stabilize. · Note the pH value
· Press on/off to turn off the tester. If you do not press a button for 5 minutes, the tester will automatically shut off to save batteries.
Paper strips – pH strips are made of paper impregnated with pH indicator. pH Measurement
· Immersed paper strip in the sample.
· Wait 10 to 20 seconds.
· Compare color of paper with scale printed on the side of the box.

City of Downey Page 1
STANDARD OPERATING PROCEDURE (SOP) FOR SPILL EMERGENCY RESPONSE
1.0 PURPOSE
To promptly notify City staff and appropriate public agencies of the occurrence of and details related to an unauthorized release of sewage. A sewage spill can be from a private property back-up or from the City-owned sanitary sewer system, which is commonly referred to as a “Sanitary Sewer Overflow” or “SSO”. Responsibility for and response to SSOs from Los Angeles Sanitation Districts (LACSD)-owned trunk sewers within City boundaries would fall on LACSD.
This Spill Emergency Response Plan (SERP) has been prepared to comply with the latest State Water Resources Control Board Order No. 2022-0103-DWQ, implemented in 2023.
The new Board Order updates the requirements into four (4) spill categories as discussed in Section 2.2.1. This Plan supersedes and replaces the City’s previous Sewer Overflow Response Plan (No. SOR01), dated January 2017.
2.0 SPILL CATEGORIES
Individual spill notification, monitoring and reporting must be in accordance with the following spill categories:
• Category 1 Spill - A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under this General Order that results in a discharge to: A surface water, including a surface water body that contains no flow or volume of water; or a drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly. 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 an Enrollee-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the Enrollee shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Requirements) of this General Order.
• 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.
• Category 3 Spill - A Category 3 spill is a spill of equal to or greater than 50 gallons and less than 1,000 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water. A spill of equal to or greater than 50 gallons and less than 1,000 gallons, that spills out of a lateral and is caused by a
SOP Spill Emergency Response Plan No. SER01 Effective Date 4/21/2023
City of Downey Page 2
failure or blockage in the sanitary sewer system is a Category 3 spill.
• Category 4 Spill - A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under this General Order that does not discharge to a surface water. A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 4 spill.
3.0 IMPORTANT REPORTING TIMELINE
Regulatory and other affected agencies require immediate notification for spills generated from City-owned and maintained sanitary sewer system. Los Angeles County Information must be called within 15 minutes when any quantity of sewage enters a storm drain or surface water. California Office of Emergency Services (OES) must be notified within 2 hours when an SSO greater than or equal to 1,000 gallons discharges to surface water or is spilled in a location where it probably will be discharged to surface water. OES will forward the information to the Los Angeles Regional Water Quality Control Board (RWQCB). Once the initial notifications are made the City can provide further updates to such entities in a timely manner.

Sewer and Storm Water Supervisor shall notify the Superintendent of Utilities and Utilities Manager for all sewer spills.
5.0 RESPONDING TO A SPILL DURING REGULAR WORKING HOURS
During regular working hours (Mon – Fri, 6:30 a.m. – 4:00 p.m.) the 3 Utilities Division crew members with the shortest response time and the Sewer and Storm Water Supervisor will respond to the emergency call. Usually, the Sewer and Storm Water Crew Member(s) closest to the site will respond first. This plan assumes that when responding to an emergency call, staff will usually have with them the necessary equipment and/or vehicles. Sewer and Storm Water staff maintain the following equipment and vehicles: Sewer Trailer, Combination Sewer Vacuum Truck, CCTV Inspection Van, Sewer Easement Rodder, safety equipment and emergency response vehicles.
The following procedure is to be followed when responding to all sewer overflow emergencies to prevent the overflow from reaching the MS4 or water bodies of the State:
A. Emergency call received by Utilities Division
B. Crewmember(s) dispatched to emergency
C. Sewer and Storm Water Supervisor and/or Lead Worker responds to call
SOP Spill Emergency Response Plan No. SER01 Effective Date 4/21/2023
City of Downey Page 5
D. First crew member(s), Lead Worker, or Supervisor to arrive at the site evaluates the situation. During evaluation the first person(s) at the site has six duties:
· Contain the spill with sandbags, preventing the spill from entering the catch basin. If sewage has already entered the storm drain system, plug the outlet pipe at the next downstream storm drain manhole or further downstream manholes, until the beginning of the flow/spill is reached.
· Determine a remedy – plan of action and what resources are needed to remedy the situation
· Determine the gallons per minute – eyeball method and times (start, containment, arrival, etc.)
· Take pictures of the overflow to be used to assist with determining spill rate and for documentation purposes.
· Notify Superintendent of Utilities and Utilities Manager whenever a sewer spill occurs
· Sewer and Stormwater Supervisor and/or Lead Worker shall call Los Angeles County Information within 15 minutes for all spills and receive a ticket number. If all information has not been gathered the Sewer and Stormwater Supervisor and/or Lead Worker shall call back and provide the ticket number referring to the case along with all information that has been collected. The Sewer and Stormwater Supervisor and/or Lead Worker shall call the California Office of Emergency Services (OES) within 2 hours when an SSO is greater than or equal to 1000 gallons or has entered the water bodies of the State.
E. Initiate plan of action.
1. As needed, call for additional help, appropriate vehicles and equipment, and/or whatever else is needed.
F. Clear blockage.
2. Once the blockage is cleared, it is very important to investigate the area for any claims of flooded or damaged homes in private lateral backups. If found, take pictures and document carefully.

Each category of spill has a different reporting time.
6.0 RESPONDING TO A SPILL, AFTER NORMAL WORK HOURS
During after-hours (Mon – Fri, 4:00 p.m. – 6:30 a.m. and Sat – Sun) the standby person will respond to the emergency call. The standby person is determined through a weekly rotation of crew members who serve on a one-week “on-call” basis. The standby person will respond to the call and call the Sewer and Storm Water Supervisor immediately. The Sewer and Storm Water Supervisor will request additional help, as needed. Although the standby person drives a Utilities vehicle to the site, he will occasionally need to arrange for additional equipment at the site.
The following procedure is to be followed when responding to all sewer overflow emergencies to prevent the overflow from reaching the MS4 or water bodies:
A. Emergency call received by emergency Standby person
B. Standby person calls the Sewer and Storm Water Supervisor C. Standby person responds to call
D. Standby person evaluates the situation. During evaluation the standby person has five duties:
· Contain the spill with sandbags, preventing the spill from entering the catch basin. If sewage has already entered the storm drain system, plug the outlet pipe at the next downstream storm drain manhole or further downstream manholes, until the beginning of the flow/spill is reached.
· Determine a remedy – plan of action and what resources are needed to remedy the situation
· Determine the gallons per minute – eyeball method and times (start, containment, arrival, etc.)

1.0 INTRODUCTION
This Water Quality Monitoring Program (WQMP) is designed for the immediate implementation of water quality sampling in the event of sanitary sewer spills within the jurisdiction of the City of Downey.
The primary objective of water quality sampling is to identify and assess the impact of contaminants that have potential risk to aquatic life as a result of Sanitary Sewer Overflows (SSOs).
This WQMP has been prepared to comply with the latest Order No. 2022-0103-DWQ, implemented in 2023, and includes enforcement provisions contained in Division 7 of the Water Code. The new Board Order updates the requirements into four (4) spill categories as discussed in Section 2.2.1.
Compliance is also included for Order No. 2013-0058-EXEC subsection D. 7 (v) of the State Waste Requirements for Sanitary Sewer Systems (SSS) and the Waste Discharges Requirements (WDRs).
In cases where Category 1 spills of 50,000 gallons or greater are discharged to surface waters, the City must conduct water quality sampling of the receiving water within 18 hours of the initial knowledge of the spill and submit a Technical Report within 45 calendar days to the Board.
1.1 OBJECTIVES
This WQMP will be used to ensure compliance with the water quality criteria during an SSO. The objectives of this program are as follows:
· Monitor water quality conditions during an SSO.
· Follow communication, response, and documentation procedures in the event of an exceedance(s) of water quality constituents.
This WQMP defines procedures for conducting the water quality monitoring in the event of an SSO.
1.2 MONITORING
The field sampling procedures constitute the water quality monitoring efforts to follow in an event of a Category 1 SSO or spill of 50,000 gallons or greater. · Section 2 includes the procedures to follow in the event of an SSO. · Section 3 describes the field sampling plan.
· Section 4 includes documentation.
2.0 SANITARY SEWER OVERFLOW
A sewage spill can occur from a private property back-up or from the publicly-owned (City) sanitary sewer system, which is commonly referred to as a Sanitary Sewer Overflow (SSO). A spill can also occur as a result of 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.

2.5 SAMPLING PROCEDURES
To preserve the integrity of the sampling process and ensure the sampling process is free from pollutants that could bias analytical results, containers that are pre- cleaned or sterilized and with preservatives, will be provided by the City’s contract laboratory (currently Weck Laboratories, Inc.).
· Gloves used during sampling can also be a source of contamination.
Sampler shall use new latex or nitrile gloves when collecting SSO samples.
· Grab samples shall be collected facing upstream. The sample shall be collected directly into the bottle provided and not touch the walls of the outfall.

· Container shall not be rinsed or overfilled. Doing so may wash out the preservatives in the bottle. If this happens, discard the container and take a new sample using a new container.
· Do not set the container cap down! Hold it with fingers away from edges and away from splashing water, and hold the lid in your hand so that the inside of the lid faces down.
· NEVER touch the inside of the cap or the container.
· As soon as the container is filled, remove from the flow, affix the cap on the container and check to make sure that your container is properly sealed, as the sample will leak if not properly closed.
2.6 FIELD TEST KITS
2.6.1 pH
pH concentrations should be measured in the field using the Hach Pocket Pro pH meter or Paper strips.
Hach Pocket Pro pH meter
Conditioning
· Condition, the Hach Pocket Pro pH tester with buffering solution 10, by immersing it in electrode storage solution or tap water for at least 30 minutes before use. Repeat with buffering solution 7 and 4 to ensure proper calibration. Use deionized water to clean probe. Or grab a Hach Pocket pro tester that has already been calibrated which will be much faster.
pH Measurement
· Press the on off button to switch the tester on.
· Dip the probe about 2 to 3 cm into sample. Stir and let the read stabilize. · Note the pH value
· Press on/off to turn off the tester. If you do not press a button for 5 minutes, the tester will automatically shut off to save batteries.
Paper strips – pH strips are made of paper impregnated with pH indicator. pH Measurement
· Immersed paper strip in the sample.
· Wait 10 to 20 seconds.

· Compare color of paper with scale printed on the side of the box.
3.0 DOCUMENTATION
Field personnel must complete the required sampling form (SSO Sampling Form) and Chain of Custody (COC) forms. All forms should be completed with the name of the sampler, the results of any field-test conducted (e.g. pH and temperature), and note anything unusual about the sample (e.g. strong odors or color, sediments etc.).
