Section 3939.16 - A Total Maximum Daily Load for Toxicity, Chlorpyrifos, and Diazinon in Calleguas Creek, Its Tributaries, and Mugu Lagoon

California Regional Water Quality Control Board (Regional Board) Resolution No. R4-2005-009 adopted on July 7, 2005 by the Regional Board, 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 Toxicity, Chlorpyrifos, and Diazinon in Calleguas Creek, its Tributaries, and Mugu Lagoon.

The Basin Plan amendment specifies final wasteload allocations (WLAs) for point source discharges and load allocations (LAs) for nonpoint source discharges of chlorpyrifos and diazinon. The Basin Plan also specifies WLAs and LAs for toxicity. The TMDL establishes an implementation plan for reducing toxicity, chlorpyrifos, and diazinon loads from point-sources and nonpoint-sources which includes a monitoring program, special studies, and a compliance schedule to meet final WLAs in 2 years after the effective date of the TMDL for point sources and final LAs in 10 years after the effective date of the TMDL for nonpoint sources.
