SANITARY SEWER OVERFLOW ONLINE REPORTING
Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by the Order and the attached Monitoring And Reporting Program Order No. WQ 2013-0058-EXEC, are necessary to assure compliance with these waste discharge requirements (WDRs). All information required to be reported into the CIWQS Online SSO Database shall be certified by the authorized individual (designee), having responsibility for the overall operation of the regulated facility or activity. Note:
this requires designee registration with the State in the CIWQS database. This designated person is also known as the legally responsible official (LRO). An enrollee may have more than one LRO.

Appendix D - Water Quality Monitoring Program Plan
WATER QUALITY MONITORING PROGRAM PLAN
To comply with Attachment E1 Section 2 Spill-Specific Monitoring Requirements of the State Water Resources Control Board Order No.WQ 2022-0103-DWQ, the City has developed and implemented this SSO Water Quality Monitoring Program to assess impacts from SSOs to for Category 1 SSOs to surface waters.
The SSO Water Quality Monitoring Program required by the SSS WDR, shall include, at minimum:
1. Contain protocols for water quality monitoring.
2. Account for spill travel time in the surface water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.).
3. Require water quality analyses for Ammonia-N,bacterial indicators, and any other relevant water quality analyses as directed by the local regulatory agency to be performed by an accredited Laboratory certified by the Environmental Laboratory Accreditation Program (ELAP).
4. Require monitoring instruments and devices used to implement the SSO Water Quality Monitoring Program to be properly maintained and calibrated, including any records to document maintenance and calibration, as necessary, to ensure their continued accuracy. i. For sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water, the Enrollee shall conduct the following water quality sampling no later than 18 hours after the Enrollee’s knowledge of a potential discharge to a surfa ce water .
Ammonia-N and any other relevant water quality analyses required by the local regulatory agencies.
Appropriate Bacterial indicator(s) per the applicable Basin Plan water quality objective , including one or more of the following, unless directed otherwise by the regional water board: Total coliform bacteria, fecal coliform bacteria, E.Coli, or Enterococcus.
Additionally, for category 1 SSO the following is required:
1.) Within three business days of the spill a draft spill report will be submitted into CIWQS.
2.) Within 15 calendar days of the spill event a certified spill report for category 1 spill must be submitted into CIWQS.
Note: If category 1 spill is over 50,000 gallons, then a spill technical report must be submitted into CIWQS within 45 calendar days for the SSO end date.
SAFETY
All City staff shall be aware and follow all safety precautions in order to comply with this Water Quality Monitoring Program. Therefore, all staff needs to take into account where monitoring will not be possible which may include:
• Heavy rain / storm events where access points may be compromised; • Flooding around low areas
• Fast moving waters or
• No safe access to site.
Appendix D - Water Quality Monitoring Program Plan
City staff should evaluate and keep safety first when encountering these scenarios and are encouraged to exercise proper judgment to limit health risk.
ESTIMATION OF SPILL TRAVEL TIME
The following method is recommended to estimate spill travel direction:
• Take visual ft/sec measurement from above, based on a floating debris, to estimate the number of feet the debris has traveled in seconds. (Note: If the first measurement is uncertain, this time estimate may be performed three to five times, and the values averaged to determine the estimate travel time. The velocity in the upper portion of the water body can then be calculated by dividing the measured distance by the average time.)
WATER QUALITY SAMPLING
In the event that a Category 1 SSO with an estimated 50,000 gallons or greater reaches surface waters or flowing drainage channel tributary to a larger body of water, City staff should take samples within 18 hours. Environmental Compliance staff and laboratory supervisor are notified.
Laboratory staff will conduct sampling efforts. The purpose of water quality sampling is to determine the nature and extent of the impact of the SSO. Water quality sampling typically includes the following unless otherwise directed by Ventura County Environmental Health Division (VCEHD) or other regulatory agencies:
• Ammonia-N. Performed by Hill Canyon Treatment Plant (HCTP) Laboratory. • Appropriate Bacterial indicator. Performed by Hill Canyon Treatment Plant Laboratory (HCTP).
The HCTP Laboratory is ELAP certified for these tests identified above.
Samples should be collected as stipulated in Water Quality Sampling Procedure below. Lab sample procedures and the locations should be recorded on an area map depicting each location of sampling. The samples should be collected as follows:
• First sample at the point in the receiving water where the sewage initially enters the receiving water.
• Second sample up stream of discharge location approximately 500 feet up stream from the discharge location, or where safe to access.
• Third sample approximately 1,000 feet down stream of the discharge location, or where safe to access. (Note: the third sample should be at the point before the conveyance system flow discharges into the receiving water)
The sampling of each of the three sites will continue daily until laboratory results indicate that the spill is no longer impacting the receiving water. This determination is made in corroboration with regulatory staff after a review and discussion of the collected data and a conclusion that the results received from the HCTP lab show that the downstream sample area has reached upstream baseline levels. It is only at this time that monitoring events at the three sites will cease.
Appendix D - Water Quality Monitoring Program Plan
WATER QUALITY SAMPLING EQUIPMENT
The following guideline describes the equipment and supplies to be stocked and readily available for any water quality sampling event.
a. Sterile sample bottles
b. Ice chest with ice/ blue ice
c. Chain of custody forms
d. Ball point pens and labeling tapes
e. Sampling pole
f. Syringes
g. Gloves
h. Other PPE (i.e. rubber boots, apron, mask, etc.)
Laboratory staff should ensure that there are adequate quantities of sample containers to accommodate sampling locations.
WATER QUALITY SAMPLING PROCEDURE
Call Laboratory Supervisor to notify him/her about the SSO event.
1. Disposable un-powdered gloves are recommended for sample collection to protect you and to assure the integrity of the samples. Disposable gloves should be changed at each sampling location.
2. Determine the correct location for sample collection.
3. Samples for bacteria/coliform analysis shall be collected in a sterile, colilert container. Sampler will submerge container, midstream of the effluent, point top into the effluent, remove cap and fill container to the 100 ml fill line.. Label sample bottle with:
a. sampling site
b. date and time sampled
c. sampler first and last name
4. Keep the samples packed on blue ice or equivalent for delivery to the laboratory.
5. Deliver all samples to the laboratory within 4 hrs.
6. Fill out Chain of Custody (COC) with the same information to match the sample bottles.
Complete the COC as thoroughly as possible and make sure to include any observations made during the sampling event. . Relinquish the COC with your signature, printed name, date, and time.
WATER QUALITY ANALYSIS-PROTOCOLS
Typical monitoring parameters may include: Ammonia-N, total and fecal coliform bacteria, E. Coli Enterococcus or other analyses as required per a discussion with regulatory staff.
Appendix D - Water Quality Monitoring Program Plan
Laboratory:
• All samples will be delivered to the Laboratory. The laboratory methods will be performed according to the laboratory’s Standard Operation Procedures (SOPs).
Maintenance and Calibration of Monitoring Instruments and Devices:
• In order to be accredited and maintain their certification, the HCTP Laboratory follows stringent quality assurance and quality control protocols that includes regular monitoring, calibration and maintenance of their equipment. The frequency of monitoring and calibration varies based on equipment type and method requirements. Records of the calibration receipts are kept on file and readily available up on request.

Upper Unit W Wastewater Interceptor
This intercepto r comprises approximately 6,900 LF of wastewater pipelines and manholes. This interceptor is located in the Conejo Arroyo north of Hillcrest Drive in the City of Thousand Oaks (see location map). The wastewater pipeline follows the Arroyo Conejo Creek, crossing the creek at several locations. In the event of a wastewa ter emergency in this reach, the following steps will be taken to expedite the repairs and eliminate the discharge of wastewater to the Arroyo Conejo Creek.
• City staff inspects the upper reach of Unit W once a month. The wastewater line is also inspected during and after storm events to check the condition of the pipeline including concrete encasements.
• A list of emergency contractors with certificates of insurance is on file in case of emergency. These contractors have been approved by City Council to be used in an emergency. The list of contractors, as well as a list of material suppliers, is located in the back of this plan.
If a wastewater emergency involves the discharge of wastewater, the City’s “Policy for Wastewater Spills and Overflows” is to be followed for agency notification and posting requirements.
The following pages are location maps showing the upper reach of the Unit W Wastewater Interceptor and manholes.

Calle Brusca Lateral
Wastewater Contingency Plan Page 14 H:\COMMON\Wastewater\Wastewater Contingency Plan\Wastewater Contingency Plan 2024 Update.docx
The lateral on Calle Brusca serves four homes on Calle Brusca. The eight-inch H.D.P.E. wastewater line is located behind the homes, drops off the canyon wall, where it then goes across the Arroyo Conejo Creek (encased in concrete) and connects to the Unit W wastewater trunk line.
Wastewater Contingency Plan Page 15 H:\COMMON\Wastewater\Wastewater Contingency Plan\Wastewater Contingency Plan 2024 Update.docx
Calle Brusca Lateral
In the event of failure, the following procedures will be followed to ensure the continuation of service for the residents and to prevent the release of wastewater in the Arroyo Conejo Creek. City staff will inspect the wastewater line during and after a s torm event to check the condition of the pipe and the encasement. This line is currently inspected every month for condition.
Staff will take preventative steps for the plugging and pumping of the line to ensure that wastewater will not be discharged into the Arroyo Conejo Creek. This included the construction of a new manhole that allows the line to be plugged and pumped at its lowest point to capture all the flow. The flow would then be pumped from manhole W15 -1 to manhole W19 -6 at the end of the cul -de-sac on Calle Brusca. Rain for Rent (phone number 525-3306) has worked with staff to provide and set up a temporary pump station.
The station can be operational in one to two days. While waiting for the temporary pump station to be operational, City staff will utilize in-house pumps and generators to start the bypass operations.
To supply a temporary electrical power source for the pumps during the bypass operation, the City will contact Rod King at Southern California Edison, 805 -494-7040, who will facilitate the installation of the temporary power supply.
The following pages show the location of the line and the temporary pump station location.

W-U63 8” Pipe Bridge
Wastewater Contingency Plan Page 22 H:\COMMON\Wastewater\Wastewater Contingency Plan\Wastewater Contingency Plan 2024 Update.docx
The W-U63 Pipe Bridge is an eight-inch wastewater line serving Lynn Ranch. This line runs from Calle Arroyo through an easement and crosses the Arroyo Conejo Creek before connecting to the Unit W wastewater interceptor pipeline at manhole W-U63. The line serves eleven homes and is supported over the Arroyo Conejo Creek by a bridge structure. During high rain flow events it may be subject to damage.
In the event of a wastewater emergency, the following procedures will be followed:
staff will plug the eight-inch line on Calle Arroyo at manhole W38-3. This will facilitate vacuuming of wastewater at this location, which will then be discharged into manhole LR1-11 on Calle Arroyo.
The following pages show the location of the line and manholes of the W-U63 8” Pipe Bridge.

Rancho Conejo Lateral
Offsite Connection to Unit W
Contingency Plan
OBJECTIVE: The purpose of this contingency plan is to provide operational service at the 10” Rancho Conejo Wastewater Lateral in the event of a major slope failure or other emergency. The lateral is located just north of Arroyo View Street and traverses the steep slope down the canyon to the Unit W Interceptor.
The following two options are available for emergency operations; 1) an above ground gravity-operated bypass using 6” flat hose, 2) a diesel operated dri -prime pump that bypasses flow through a 6” force -main then via gravity to the Sappanwood Avenue wastewater line.
(1) PROCEDURES FOR 6” GRAVITY OPERATED BYPASS
1. This option transfers flow from manhole W1-2 to W1-1 via temporary gravity line. (Tract 4366-2/Drawing 10706,
attached)
a. Verify that the line below manhole W1-1 is intact and operational.
b. Retrieve approximately 400 feet of 6” wastewater flat hose from the Municipal Service Center (MSC),
located inside building B.
c. Connect the hose camlock fitting to the vent stack
camlock fitting (1) on manhole W1-2 (see pages 28
and 29). Proceed laying out and connecting flat
hose until manhole W1-1 is reached.
d. Connect end hose camlock fitting to the vent stack
camlock fitting (1) of manhole W1-1. You should
have an unobstructed connection between both
structures at this point.
e. Open the 6” downstream valve (2) located below the
6” tee of the vent stack on W1-1 (see page 29).
f. Return to upstream manhole W1-2 and open the 6”
(2) valve located below the 6” tee of the vent stack.
g. At the W1-2 upstream manhole, begin to close the
10” downstream valve (3) located on the permanent
wastewater line (see page 28). Monitor the 6”
emergency line at both manholes during the charging
process.
Wastewater Contingency Plan Page 29 H:\COMMON\Wastewater\Wastewater Contingency Plan\Wastewater Contingency Plan 2024 Update.docx
h. After the emergency line appears operational, begin
to open the vent stack valve (4) at both manholes
W1-2 and W1-1 to a position of approximately 50%
open.
i. Continue to monitor the emergency line, and retrieve the 6” Dri Pump as alternative #2.
Follow the City’s Wastewater-Related Spills and Overflows Policy for proper reporting and corrective action.
(2) PROCEDURES FOR OPERATING THE 6” DRI PUMP AND
FORCE MAIN
2. This option transfers flow via portable pump from the 10” Rancho Conejo Lateral to the Lawrence Drive 6” force main and the Sappanwood Street gravity line. (See drawing of 6” force main and staging area on page 27, and site plan on page 30.)
a. Retrieve the following from the MSC:
i. Godwin 6” trailer mounted dri-prime pump
(check fuel tank level).
ii. (1) 25-foot non-collapsible Kanaflex suction
hose with strainer and 6” cam lock fitting.
iii. (1) 25-foot non-collapsible Kanaflex discharge
hose with 6” cam lock male and female
fittings.
b. Transport trailer and equipment to the staging area
on Arroyo View Street.
c. Open 32” wet well cover (1) and insert 25-foot
suction hose. Connect suction hose to suction side
of the 6” pump.
d. Connect 25-foot discharge hose to the discharge
side of the 6” pump. Open discharge cover (2) and
connect discharge hose to the discharge cam lock
fitting (3), at the staging site. Verify all fittings are secure.
e. Start the 6” Dri Prime pump and set to idle at
approximately 600-800 rpms.
f. Verify that the 6” return line valve (6A) is closed. g. Open the inlet valve (8A) slowly and monitor inlet
flow from the 10” mainline.
h. Slowly close the 10” main wastewater pipeline valve
(10A). Monitor the flow through the 6” pump and
verify proper operation.
i. Monitor downstream flow at Sappanwood Avenue
manhole W1-2D and verify that it matches the flow
produced at the staging site.
Wastewater Contingency Plan Page 30 H:\COMMON\Wastewater\Wastewater Contingency Plan\Wastewater Contingency Plan 2024 Update.docx
j. After repairs to Rancho Conejo lateral are complete
and bypass pumping is no longer required, open
mainline valve (10A) to establish flow back to Unit W.
After flow is established, lower the pump speed
gradually and shut the pump off. Open 6” return line
valve 6A to allow for force main residual to flow back
into the wet well. With the 8” valve open (8A), allow
residual in the wet well to flow into the main line and down to Unit W.
k. Remove all fittings, wash down wet well with an air- gapped hose, close valves (6A) and (8A), and secure
all covers. Return the pump back to the proper
location at the Municipal Service Center and fill up
fuel tank.
