Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Los Angeles Regional Water Quality Control Board (Regional
					 Board) Resolution No. R4-2008-007, adopted on May 1, 2008, modified the
					 regulatory provisions of the Water Quality Control Plan for the Los Angeles
					 Region (Basin Plan) by:
(1) revising
				  the Table of Contents,
(2) adding
				  introductory text for Chapter 7 (Total Maximum Daily Loads), and
(3) establishing a Total Maximum Daily Load
				  (TMDL) for Trash in the Malibu Creek Watershed.
In the Malibu Creek Watershed, Malibu Creek from Malibu
					 Lagoon to Malibu Lake, Medea Creek Reaches 1 and 2, Lindero Creek Reaches 1 and
					 2, Lake Lindero, and Las Virgenes Creek have been listed under the federal
					 Clean Water Act section
					 303(d) as not
					 meeting standards due to excessive trash accumulated in water. The amendment
					 establishes the numeric target with which wasteload allocations for point
					 source discharges and load allocations for nonpoint source discharges are
					 calculated. The proposed TMDL establishes an eight-year implementation schedule
					 for point source dischargers. However, the water quality objective of zero
					 trash, as defined in the TMDL, shall be attained in five years for nonpoint
					 source dischargers. In addition to a brief description of the Malibu Creek
					 Watershed and the existing conditions contributing to water quality problems,
					 the Basin Plan amendment also includes numeric targets, source analysis,
					 linkage analysis, wasteload allocations, load allocations, margin of safety,
					 critical conditions, an implementation plan, and compliance schedules.
The Regional Board adopted Resolution No. R18-006 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 Malibu Creek 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 areas.
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.
