Attachment 3 — Burbank City Council, April 22, 2025 (part 2 of 2)

Footnotes for Spill Reporting Requirements
1 Spill - 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. Exfiltration of sewage is not considered to be a spill under this General Order if the exfiltrated sewage remains in the subsurface and does not reach a surface water of the State.

See Statewide ORDER WQ 2022-0103-DWQ, page A-4.

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.

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 2 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 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.

See Statewide ORDER WQ 2022-0103-DWQ, page 24 and 25.
2 Private Lateral Sewage Discharges – Private Lateral Sewage Discharges – Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee’s sanitary sewer system or from other private sanitary sewer system assets may be voluntarily reported to the CIWQS Sewer System Database. 3 If there are No Spills or Category 4 Spills during the calendar month, the Enrollee will provide, within 30 calendar days after the end of each calendar month, either a “No -Spill” certification statement, or a “Category 4 Spills” certification statement, in the online CIWQS Sanitary Sewer System Database, certifying that there were either no spills, or Category 4 Spills that will be reported annually for the designated month. Although monthly reporting of individual Category 4 spills is not required, the City is required to report the total spill volume and spill count associated with Category 4 spills. For more information, see footnote 10 for monthly reporting requirements.

Water Quality Monitoring Program

CITY OF BURBANK

PUBLIC WORKS DEPARTMENT

WATER QUALITY MONITORING PROGRAM
To comply with of the State Water Resources Control Board Order No. WQ 2022-0103-DWQ, the City has developed and implemented this Water Quality Monitoring Program to assess impacts from spills.

SAFETY AND ACCESS EXEMPTIONS
All City staff shall be aware and follow all safety precautions to comply with this Water Quality Monitoring Program. Therefore, all staff needs to consider where monitoring will not be possible which may include:

1. Heavy rain / storm events where access points may be compromised.

2. Flooding around low areas; or

3. M oving waters.

City staff should evaluate and keep safety first when encountering these scenarios and are encouraged to exercise proper judgment to limit health risk.

If access restrictions or unsafe conditions are encountered that prevents compliance with spill response requirements or monitoring requirements, documentation of access restrictions and/or safety hazards shall be provided in the corresponding required report.

WATER QUALITY SAMPLING
For sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water, the Cit
y staff shall conduct the following water quality sampling no later than 18 hours after the staff’s knowledge of a potential discharge to a surface water:
• C ollect one water sample, each day of the duration of the spill at :
o T he DCS-001 location as described in Table 1 below if sewage discharges to a surface water via a drainage conveyance system; and/or
o E ach of the three receiving water sampling locations in Table 2.

Table 1: Location for Sampling of Flow in Drainage Conveyance System (DCS) Prior to Discharge Sampling Location Sampling Location Description
DCS-001 A point in a drainage conveyance system before the drainage conveyance system flow discharges into a receiving water.

Water Quality Monitoring Program
Table 2: Locations for Receiving Surface Water Sampling (RSW)1 Sampling Location Sampling Location Description
RSW-001
Point of Discharge
A point in the receiving water where sewage initially enters the receiving water.

RSW-001U:

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

RSW-001D:

Downstream of Point of Discharge
A point in the receiving water, downstream of the point of sewage discharge, where the spill material is fully mixed with the receiving water.
1 The staff must use their best professional judgment to determine the upstream and downstream distances based on receiving water flow, accessibility to upstream/downstream waterbody banks, and size of visible sewage plume.

If the receiving water has no flow during the duration of the spill, the staff must report “No Sampling Due to No Flow” for its receiving water sampling locations.

Per Order No. WQ 2022-0103-DWQ, monitoring for sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water (receiving waters) includes samples from the locations identified in Table 1, if feasible. Analysis of samples collected will include the following constituents:

1. Ammonia, and

2. Appropriate bacterial indicator(s) per the applicable Basin Plan water quality objectives, including one or more of the following, unless directed otherwise by the Regional Water Board:
i. Total Coliform Bacteria
ii. Fecal Coliform Bacteria
iii. E- coli
iv. Enterococcus

The Basin Plan identifies the City of Burbank receiving waters as the Burbank Western Channel (BWC) and Los Angeles River (LAR). The BWC and LAR are further categorized as “REC-1” (“Fresh water designated for water contact recreation). Per the Basin Plan, REC-1 water bodies require E. coli monitoring only. The other bacterial indicators, total coliform, fecal coliform, and enterococcus are applicable to marine waters and do not apply to the BWC and LAR because they are freshwater bodies.

Therefore, in the event of a sewage spill in which an estimated 50,000 gallons or greater is discharged and reaches a designated water body of the State of California (receiving water), the City of Burbank shall monitor for:
i. Ammonia
ii. E.coli
Spill monitoring must be representative of the monitored activity as adhering to the following requirements:

Sufficiently Sensitive Methods
Sample analysis must be conducted according to sufficiently sensitive test methods approved under 40 Code of Federal Regulations Part 136 (eCFR :: 40 CFR 136.6 -- M ethod modifications and analytical
requirements.) for the sample analysis of pollutants. For the purposes of this General Order, a method is sufficiently sensitive when the minimum level of the analytical method approved under 40 Code of Federal Regulations Part 136 is at or below the receiving water pollutant criteria.

The water body that received or will receive the discharge. (b) An estimate of the amount of sewage or other waste released and the (c) amount that reached a surface water at the time of notification.

If ongoing, the estimated flow rate of the release at the time of the (d) notification.

The name, organization, phone number and email address of the reporting (e) representative.

Monitoring b.

For spills, overflows and bypasses reported under section VI.C.6.a, the Permittee shall monitor as required below:

To define the geographical extent of the spill’s impact, the Permittee shall i. obtain grab samples (if feasible, accessible, and safe) for all spills, overflows or bypasses of any volume that reach any waters of the state (including surface and ground waters). For spills that reach freshwaters, the Permittee shall monitor for E. coli density. For spills that reach marine waters, the permittee shall monitor for total coliform, fecal coliform and enterococcus density. For spills that reach fresh or marine waters, the permittee shall also monitor for relevant pollutants of concern, upstream and downstream of the point of entry of the spill (if feasible, accessible, and safe). This monitoring shall be done on a daily basis from the time the spill is known until the results of two consecutive sets of bacteriological monitoring indicate the return to the background level or the County Department of Public Health authorizes cessation of monitoring.

Reporting c.

The initial notification required under section VI.C.6.a shall be followed by:

As soon as possible, but not later than twenty-four hours after becoming aware i. of an unauthorized discharge of sewage or other waste from its wastewater treatment plant to a water of the state, the Permittee shall submit a statement to the Regional Water Board by email at
[email protected]
. If the discharge is 1,000 gallons or
more, this statement shall certify that OES has been notified of the discharge in Attachment 3 - Page 183

The name of the local health officer or director of environmental health (g) representative notified (if contacted directly); the date and time of notification; and the method of notification (e.g., phone, fax, email).

A written preliminary report five working days after disclosure of the incident is ii. required. Submission to the Regional Water Board of the California Integrated Water Quality System (CIWQS) Sanitary Sewer Overflow event number shall satisfy this requirement. Within 30 days after submitting the preliminary report, the Permittee shall submit the final written report to this Regional Water Board. (A copy of the final written report, for a given incident, already submitted pursuant to a statewide General WDRs for Wastewater Collection System Agencies, may be submitted to the Regional Water Board to satisfy this requirement.) The written report shall document the information required in paragraph d below, monitoring results and any other information required in provisions of the Standard Provisions document including corrective measures implemented or proposed to be implemented to prevent/minimize future occurrences. The Executive Officer for just cause can grant an extension for submittal of the final written report.

The mandatory information included in SSO online reporting for finalizing and viii. certifying the SSO report for each spill, overflow, or bypass under the SSO WDR.

Activities Coordination e.

Although not required by this Order, Regional Water Board expects that the POTW’s owners/operators will coordinate their compliance activities for consistency and efficiency with other entities that have responsibilities to implement: (i) this NPDES permit, including the Pretreatment Program, (ii) a Municipal Separate Storm Sewer Systems (MS4) NPDES permit that may contain spill prevention, sewer maintenance, reporting requirements and (iii) the SSO WDR.

Consistency with SSO WDRs f.

The CWA prohibits the discharge of pollutants from point sources to surface waters of the United States unless authorized under an NPDES permit. (33 United States Code sections 1311, 1342). The State Water Board adopted General Waste Discharge Requirements for Sanitary Sewer Systems, (WQ Order No. 2006-0003- DWQ; SSO WDR) on May 2, 2006, to provide a consistent, statewide regulatory approach to address sanitary sewer overflows. The SSO WDR requires public agencies that own or operate sanitary sewer systems to apply for coverage under the SSO WDR, develop and implement sewer system management plans, and report all SSO to the State Water Board’s online SSOs database. Regardless of the coverage obtained under the SSO WDR, the Permittee’s collection system is part of the POTW that is subject to this NPDES permit. As such, pursuant to federal regulations, the Permittee must properly operate and maintain its collection system (40 CFR part 122.41 (e)), report any non-compliance (40 CFR part 122.41(1)(6) and (7)), and mitigate any discharge from the collection system in violation of this NPDES permit (40 CFR part 122.41(d)).

The requirements contained in this Order in sections VI.C.3.b (SCCP Plan section), VI.C.4 (Construction, Operation and Maintenance Specifications section), and VI.C.6 (Spill Reporting Requirements section) are intended to be consistent with the requirements of the SSO WDR. The Regional Water Board recognizes that there may be some overlap between these NPDES permit provisions and SSO WDR requirements, related to the collection systems. The requirements of the SSO WDR are considered the minimum thresholds (see finding 11 of State Water Board Order No. 2006-0003-DWQ). To encourage efficiency, the Regional Water Board will accept the documentation prepared by the Permittees under the SSO WDR for compliance purposes as satisfying the requirements in sections VI.C.3.b, VI.C.4, and VI.C.6 provided the more stringent provisions contained in this NPDES permit Attachment 3 - Page 185
CITY OF BURBANK ORDER R4-2017-0064
BURBANK WATER RECLAMATION PLANT NPDES NO. CA0055531

LIMITATIONS AND DISCHARGE REQUIREMENTS (VERSION: Adopted 03/02/2017) 23 are also addressed. Pursuant to SSO WDR, section D, provision 2(iii) and (iv), the provisions of this NPDES permit supersede the SSO WDR, for all purposes, including enforcement, to the extent the requirements may be deemed duplicative.

7. Compliance Schedules – Not Applicable
VII. COMPLIANCE DETERMINATION
Compliance with the effluent limitations contained in section IV of this Order will be determined as specified below:

A. General
Compliance with effluent limitations for priority pollutants shall be determined using sample reporting protocols defined in the MRP and Attachment A of this Order. For purposes of reporting and administrative enforcement by the Regional and State Water Boards, the Permittee shall be deemed out of compliance with effluent limitations if the concentration of the priority pollutant in the monitoring sample is greater than the effluent limitation and greater than or equal to the reporting level (RL).

B. Multiple Sample Data
When determining compliance with a measure of central tendency (arithmetic mean, geometric mean, median, etc.) of multiple sample analyses and the data set contains one or more reported determinations of DNQ or ND, the Permittee shall compute the median in place of the arithmetic mean in accordance with the following procedure:

The data set shall be ranked from low to high, ranking the reported ND determinations 1. lowest, DNQ determinations next, followed by quantified values (if any). The order of the individual ND or DNQ determinations is unimportant.

The median value of the data set shall be determined. If the data set has an odd number 2. of data points, then the median is the middle value. If the data set has an even number of data points, then the median is the average of the two values around the middle unless one or both of the points are ND or DNQ, in which case the median value shall be the lower of the two data points where DNQ is lower than a value and ND is lower than DNQ.

C. Average Monthly Effluent Limitation (AMEL)
If the average (or when applicable, the median determined by subsection B above for multiple sample data) of daily discharges over a calendar month exceeds the AMEL for a given parameter, this will represent a single violation, though the Permittee may be considered out of compliance for each day of that month for that parameter (e.g., resulting in 31 days of non- compliance in a 31-day month). If only a single sample is taken during the calendar month and the analytical result for that sample exceeds the AMEL, the Permittee may be considered out of compliance for that calendar month. The Permittee will only be considered out of compliance for days when the discharge occurs. For any one calendar month during which no sample (daily discharge) is taken, no compliance determination can be made for that calendar month with respect to the AMEL.

If the analytical result of a single sample, monitored monthly, quarterly, semiannually, or annually, does not exceed the AMEL for a given parameter, the Permittee will have demonstrated compliance with the AMEL for each day of that month for that parameter.

If the analytical result of any single sample, monitored monthly, quarterly, semiannually, or annually, exceeds the AMEL for any parameter, the Permittee may collect up to four additional samples within the same calendar month. All analytical results shall be reported in the monitoring report for that month. The concentration of pollutant (an arithmetic mean or a Attachment 3 - Page 186
