Section 3936 - A Total Maximum Daily Load for Trash for the Ballona Creek and Wetland(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.
