Section 3935 - A Total Maximum Daily Load for Trash for the los Angeles River Watershed

(a) Regional Board Resolution No. 2007-012 adopted on August 9, 2007 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 Los Angeles River, and (3) adding text to Chapter 7 (Total Maximum Daily Loads Summaries) which establishes a Total Maximum Daily Load (TMDL) for Trash for the Los Angeles River Watershed. This TMDL addresses the impairment of water quality due to trash being discharged to the river via municipal storm drains; and will be implemented primarily 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 sets baseline waste load allocations for each responsible jurisdiction based on trash generation per land use within its boundaries; and establishes a schedule for progressive reductions from the baseline, over a period of nine years, until the numeric target is reached. California Department of Transportation and the Los Angeles County Department of Public Works and its municipal storm water co-permittees are the responsible jurisdictions under this TMDL. To the extent nonpoint source implementation of load allocations is necessary, it will be accomplished, consistent with the Plan for Nonprofit Source Pollution Control Policy.

Responsible jurisdictions have the option of installing Executive Officer certified full capture systems, or implementing a combination of partial-capture trash best management practices and institutional controls in order to meet compliance requirements. An implementation report, outlining how responsible agencies intend to comply with the TMDL, will be prepared six months after the effective date of the TMDL. The implementation phase of the TMDL is scheduled to begin on September 30, 2008. Compliance with the TMDL numeric target must be demonstrated no later than September 30, 2016.

(b) 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 Load 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. 2007-012 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.
