California Code of Regulations › Title 23 - Waters › Division 4 - Regional Water Quality Control Boards › Chapter 1 - Water Quality Control Plans, Policies, and Guidelines › Article 4 - Los Angeles Region › Section 3939.25 - Basin Plan Amendment to Incorporate a Variance Provision for the Groundwater Mineral Quality Objectives

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On March 9, 2006, the Los Angeles Regional Water Quality
					 Control Board (Los Angeles Water Board) adopted Resolution No. 2006-003
					 amending the Water Quality Control Plan for the Los Angeles Region (Basin
					 Plan). The amendment revises Basin Plan Chapter 3, "Water Quality Objectives,"
					 to incorporate a variance provision for groundwater mineral water quality
					 objectives (contained in Table 3-10 of the 1994 version of the Basin Plan).
					 This authority allows the Los Angeles Water Board to approve permit-specific
					 variances for the groundwater mineral quality objectives. The variances are to
					 be limited in geographic scope to coastal aquifers where elevated
					 concentrations of minerals are caused by natural sources due to an aquifer's
					 proximity to the coast.
A discharger must submit to the Executive Officer a written
					 request for a variance from compliance with the mineral quality objectives for
					 groundwater. The Los Angeles Water Board may only grant a variance after a duly
					 noticed public meeting. The Los Angeles Water Board's decision to grant or to
					 deny a variance shall be based on evidence in the record. The Los Angeles Water
					 Board may only grant a variance when it determines that the request satisfies
					 the conditions specified in the amendment and that the variance is in the
					 public interest. In granting a variance, the Los Angeles Water Board must
					 include appropriate requirements in the Waste Discharge Requirements or
					 enforcement order consistent with the State Water Resources Control Board's
					 anti-degradation resolution (State Water Board Resolution. No. 68-16) and other
					 applicable water quality standards specified in regional and statewide water
					 quality control plans.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Resolution No. 2006-022, adopted on November 9, 2006 by the
					 Los Angeles Regional Water Quality Control Board, amended the regulatory
					 provisions of the Water Quality Control Plan for the Los Angeles Region (Basin
					 Plan), by incorporating water-effect ratios (WERs) that modify the copper water
					 quality criteria for Lower Calleguas Creek and Mugu Lagoon in the Calleguas
					 Creek Watershed in Ventura County. The WERs shall be applied as multipliers to
					 the copper water quality criteria contained in the federally promulgated
					 California Toxics Rule (CTR) as set forth in 40 Code of Federal Regulations
					 section 131.38. The WERs modify the
					 current acute (1-hour average) and chronic (4-day average) copper criteria set
					 to protect aquatic life for these waters. The WERs are used to modify the
					 criteria for copper in a manner that considers site-water chemistry, as
					 compared to laboratory water chemistry, to ensure the criteria are as
					 protective of aquatic life as was intended by the CTR. For Mugu Lagoon (Reach
					 1), the site-specific WER for copper is 1.51. For the Lower Calleguas Creek
					 (Reach 2), the site-specific WER for copper is 3.69. The Basin Plan amendment
					 also specifies water monitoring requirements and other provisions relating to
					 the applicability of the WERs.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On October 1, 2009, the Los Angeles Regional Water Quality
					 Control Board (Los Angeles Water Board) adopted Resolution No. R09-006,
					 amending the Water Quality Control Plan for the Los Angeles Region by
					 establishing a Total Maximum Daily Load (TMDL) for polychlorinated biphenyls,
					 organochlorine pesticides (chlordane, dieldrin, DDT and derivatives), and
					 sediment toxicity in McGrath Lake. The TMDL includes numeric targets for
					 sediment based on Effects Range-Low sediment quality guidelines compiled by the
					 National Oceanic and Atmospheric Administration and numeric targets for the
					 water column based on California Toxics Rule criteria for protection of human
					 health. The TMDL includes load allocations for discharges from the watershed to
					 the lake and for internal sources from the lake sediments.
The load allocations for the discharges from the watershed
					 to the lake will be implemented through the Conditional Waiver of Waste
					 Discharge Requirements for Discharges from Irrigated Lands or other appropriate
					 Los Angeles Water Board Orders. The load allocations for the lake sediments
					 will be implemented through a Memorandum of Agreement (MOA) among the Los
					 Angeles Water Board and cooperative parties. The TMDL requires cooperative
					 parties to enter into an MOA with the Los Angeles Water Board within two years
					 of the effective date of the TMDL and to submit a work plan for remediation
					 within three years of the effective date of the TMDL. If an MOA is not
					 established, or the cooperative parties do not comply with the terms of the
					 MOA, or if the MOA otherwise does not result in attainment of load allocations,
					 the TMDL requires the Executive Officer of the Los Angeles Water Board to
					 identify and issue appropriate regulatory orders to responsible parties for
					 contaminated lake sediment remediation. The TMDL requires responsible parties
					 for the load allocations for the discharges from the watershed to submit a
					 monitoring and reporting plan within six months of the effective date of the
					 TMDL.
The TMDL requires the load allocations for the discharges
					 from the watershed to the lake to be attained within ten years of the effective
					 date of the TMDL. The TMDL requires the load allocations for the lake sediments
					 to be attained within 14 years of the effective date of the TMDL.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On July 8, 2010, the Los Angeles Regional Water Quality
					 Control Board adopted Resolution No. R10-006, amending the Water Quality
					 Control Plan for the Los Angeles Region by establishing a Total Maximum Daily
					 Load (TMDL) for indicator bacteria in the Santa Clara River (SCR) Estuary and
					 Reaches 3, 5, 6 and 7. The TMDL sets numeric targets for indicator bacteria
					 based on numeric water quality objectives provided in the Basin Plan. The TMDL
					 establishes final waste load allocations (WLAs) for point source discharges,
					 final load allocations (LAs) for nonpoint source discharges, interim LAs for
					 nonpoint source discharges and interim WLAs for city and county Municipal
					 Separate Storm Sewer System (MS4) discharges. Final allocations to achieve the
					 single sample maximum numeric targets are expressed as "allowable exceedance
					 days" and only apply to days in which single sample limits are exceeded and do
					 not apply to days where geometric mean limits are exceeded. No exceedance days
					 of the geometric mean targets are allowed. Allowable exceedance days are
					 further separated into dry weather and wet weather allowances. The TMDL
					 requires the city and county MS4 dischargers and nonpoint source dischargers to
					 achieve the final WLAs and LAs within 11 years for dry weather and 17 years for
					 wet weather. Other point source dischargers must achieve WLAs upon the
					 effective date of the TMDL.
Compliance with the city and county MS4 WLAs is based on
					 the allowable number of exceedance days, except in wet weather, when compliance
					 can alternatively be based on an allowable load of bacteria. Compliance with
					 the city and county MS4 WLAs is assessed using a combination of in-stream and
					 MS4 outfall monitoring. Compliance with the WLAs assigned to other point source
					 dischargers is assessed through permit requirements. Compliance with nonpoint
					 source load allocations is assessed through compliance with waste discharge
					 requirements, waivers, or prohibitions.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On December 8, 2016, the Los Angeles Regional Water Quality
					 Control Board adopted Resolution No. R16-009, amending the Water Quality
					 Control Plan for the Los Angeles Region (Basin Plan) by establishing an
					 Implementation Plan for two TMDLs previously established by U.S. EPA. U.S. EPA
					 established the Malibu Creek Watershed TMDL for Nutrients on March 21, 2003
					 (2003 TMDL) and the Malibu Creek and Lagoon TMDL for Sedimentation and
					 Nutrients to Address Benthic Community Impairments on July 2, 2013 (2013 TMDL).
					 The 2003 TMDL applies to the whole watershed, while the 2013 TMDL applies to
					 the eastern portion of the watershed below Malibou Lake as well as four lakes:
					 Malibou Lake, Sherwood Lake, Westlake Lake, and Lindero Lake.
The Implementation Plan describes the regulatory tools,
					 implementation alternatives, implementation schedule, and associated monitoring
					 requirements to achieve the load allocations (LAs) and waste load allocations
					 (WLAs) assigned by the two U.S. EPA-established TMDLs. It does not alter any of
					 the technical elements of the two U.S. EPA-established TMDLs. The
					 Implementation Plan specifies that the WLAs will be incorporated into the Los
					 Angeles County and Ventura County MS4 Permits, the California Department of
					 Transportation Statewide Storm Water Permit, and the Tapia Water Reclamation
					 Facility NPDES Permit. The LAs will be incorporated into WDRs or conditional
					 waivers of WDRs consistent with the State Water Board's Policy for
					 Implementation and Enforcement of the Nonpoint Source Pollution Control
					 Program. The Implementation Plan establishes timeframes for achieving the
					 nutrient WLAs and LAs ranging from immediately to 13.5 years depending on the
					 source. The sedimentation WLAs and LAs must be achieved by 2025 if an
					 individual compliance approach is chosen and within 15 years if a
					 watershed-wide compliance approach is chosen. The monitoring program consists
					 of two components:
(1) TMDL
				  effectiveness monitoring to assess implementation progress and attainment of
				  numeric targets, and
(2) compliance
				  monitoring to determine compliance with the WLAs and LAs.
