Los Angeles Regional Water Quality Control Board (Los Angeles Water Board) Resolution No. R4-2007-007, adopted on June 7, 2007 by the Los Angeles Water Board, modified the regulatory provisions of the Water Quality Control Plan for the Los Angeles Region by:
The amendment establishes the numeric target with which wasteload allocations for point source discharges and load allocations for nonpoint source discharges are calculated. Wasteload allocations will be implemented through storm water permits via the authority vested in the Executive Officer by section 13267 of the Porter-Cologne Water Quality Control Act (Water Code section 13000 et seq.). Load allocations shall be implemented through either (1) a conditional waiver from waste discharge requirements, or (2) an alternative program implemented through waste discharge requirements or an individual waiver or another appropriate order of the Los Angeles Water Board.
The Regional Board adopted Resolution No. R18-005 on June 14, 2018 revising the TMDL to align the implementation requirements in the existing TMDL with the scope of the "Amendment to the Water Quality Control Plan for Ocean Waters of California to Control Trash" and "Part 1 Trash Provisions of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries," known as the statewide Trash Amendments. In accordance with the statewide Trash Amendments, MS4 permittees assigned WLAs in the Revolon Slough and Beardsley Wash Trash TMDL are only required to address point source discharges of trash in priority land use areas in the MS4. The revised TMDL requires nonpoint source responsible entities to revise their trash monitoring and reporting plans to increase the frequencies and locations of trash collection events to address any trash potentially discharged from non-priority MS4 land use ares.
The revised TMDL also removes the waivers of Waste Discharge Requirements to regulate nonpoint sources of trash and replaces the requirement with language referencing the statewide Policy for Implementation and Enforcement of the Nonpoint Source Pollution Control Program. The revised TMDL also separates requirements for the California Department of Transportation from requirements for other MS4 permittees, consistent with the statewide Trash Amendments.
