Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Regional Board Resolution No. 01-014, adopted on September 19, 2001 by the Los
				  Angeles Regional Water Quality Control Board, modified the Regulatory
				  provisions of the Water Quality Plan for the Los Angeles Region (Basin Plan) by
				  (1) revising the Table of Contents and the List of Figures, Tables, and
				  Inserts, (2) adding text to Chapter 3 (Water Quality Objectives) to reference
				  specific guidelines for the Ballona Creek and Wetland, and (3) adding text to
				  Chapter 7 (Total Maximum Daily Loads Summaries) which establishes a Total
				  Maximum Daily Load (TMDL) for Trash for the Ballona Creek and Wetland. This
				  TMDL addresses the impairment of water quality due to trash being discharged to
				  the creek via municipal storm drains; and will be implemented through the
				  National Pollutant Discharge Elimination System storm-water permits.
The numeric target of zero trash in the river implicitly
					 incorporates a margin of safety, based on a conservative interpretation of
					 narrative water quality objectives. The TMDL establishes a schedule for
					 progressively reducing the amount of trash discharged by ten percent per year,
					 until the target is reached. California Department of Transportation and the
					 Los Angeles County Department of Public Works and its municipal storm water
					 co-permittees are responsible for trash discharged from the storm drains to the
					 Ballona Creek and Wetland, and have been assigned default waste load
					 allocations. The permittees are required to submit a plan for baseline
					 monitoring to refine the waste load allocations within 30 days of the Regional
					 Board's request as authorized by Section
					 13267 of the
					 California Water Code. After a period of baseline monitoring, the
					 implementation phase of the TMDL is scheduled to begin on October 1, 2003.
					 Compliance with the TMDL numeric target must be demonstrated no later than
					 September 30, 2015.
(b) On
				  March 4, 2004, the Los Angeles Regional Water Quality Control Board adopted
				  Resolution No. 2004-023 amending the Total Maximum Daily Load for Trash in the
				  Ballona Creek and Wetland contained within the Water Quality Control Plan for
				  the Los Angeles Region. The amendment revises the definition of "full-capture
				  device" and would allow for both single devices and treatment trains or
				  "systems." Full capture devices and systems must be sized to handle the flow
				  from a one-year, one-hour storm. The amendment provides the equation and
				  isohyetal map to be used for sizing the full capture devices and
				  systems.
(c) On June 11, 2015, the
				  Los Angeles Regional Water Quality Control Board adopted Resolution No.
				  R15-006, amending the Basin Plan to revise the Total Maximum Daily Loads for
				  Trash in the Los Angeles River Watershed and the Total Maximum Daily Load for
				  Trash in the Ballona Creek Watershed.
The Basin Plan Amendment, adopted by Resolution No.
					 R15-006, revises the TMDL adopted by Resolution No. 01-014 by clarifying and
					 assigning load allocations for nonpoint sources to entities that own and/or
					 operate parks, open space, or recreational facilities located adjacent to the
					 river, estuary, and accompanying tributaries. The TMDL was further revised to
					 provide added flexibility for implementing the TMDL and demonstrating
					 compliance and includes additional receiving monitoring and nonpoint source
					 monitoring.
