§ 3939.39. A Total Maximum Daily Load for Polychlorinated Biphenyls, Organochlorine Pesticides, and Sediment Toxicity in McGrath Lake.
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.
