§ 3961. Establishment of a Total Maximum Daily Load for Sedimentation/Siltation for the Alamo River.
Regional Board Resolution No. 01-100, adopted on June 27, 2001, by the Colorado River Basin Regional Water Quality Control Board, modified the regulatory provisions of the Water Quality Control Plan for the Colorado River Basin Region (Basin Plan) by establishing a Total Maximum Daily Load (TMDL) for sedimentation/siltation in the Alamo River. The amendment to the Basin Plan requires the farmers/operators discharging agricultural return flows into the Alamo River and its tributary drains to implement best management practices to reduce silt/sediment delivery into the Alamo River, in accordance with a time schedule consisting of four phases. Each phase consists of about a three-year period with interim silt/sediment load reductions for each phase. Implementation of the TMDL does not take place until one year after the U.S. Environmental Protection Agency approves the TMDL. The amendment also requires the Imperial Irrigation District to submit and implement a revised drain water quality improvement plan, with a monitoring program, for the drains discharging into the Alamo River. A net reduction of 47% of the current sediment/silt load in the Alamo River is required by the TMDL.
