Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Los Angeles Regional Water Quality Control Board (Los
					 Angeles Water Board) Resolution No. R4-2007-006, 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:
(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
				  for trash in Machado Lake.
The amendment establishes the numeric target with which
					 zp190 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. R19-004 on March
					 14, 2019 revising the Machado Lake Trash TMDL in light 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.
					 The Los Angeles Water Board determined that the implementation requirements in
					 the existing Machado Lake Trash TMDL should not be aligned with the scope of
					 the statewide Trash Amendments because there is a potential for non-priority
					 land use areas to discharge significant amounts of trash. Additionally, it
					 could not be determined whether the Minimum Frequency of Assessment and
					 Collection (MFAC) program downstream could effectively control trash from these
					 non-priority land use areas. Therefore, storm water dischargers assigned
					 wasteload allocations will still be required to address point sources of trash
					 in all land use areas.
The revised TMDL 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.
