§ 3966. Total Maximum Daily Load for Sedimentation/Siltation for the Niland 2, P, and Pumice Imperial Valley Drains and Implementation Plan.
On January 19, 2005, the Colorado River Basin Regional Water Quality Control Board (Colorado River Basin Water Board) adopted Resolution No. R7-2005-0006 to modify the regulatory provisions of the Water Quality Control Plan for the Colorado River Basin Region by establishing: (1) a Total Maximum Daily Load (TMDL) for sedimentation/siltation in the Imperial Valley Drains: Niland 2, P, and Pumice Drains, and Implementation Plan, (2) an implementation plan for all Imperial Valley drains that empty directly into the Salton Sea, and (3) a prohibition for discharge of silt-laden tailwater into the Imperial Valley, including the Imperial Valley drains, New River, and Alamo River.
A net reduction of about 51 percent of sediment/silt in the Niland 2, P, and Pumice drains is required. The implementation plan requires farm landowners, renters/lessees, and operators/growers to implement management practices to reduce silt/sediment delivery into all drains that empty directly into the Salton Sea, in accordance with a time schedule consisting of four phases. Each phase consists of a two- or three-year period, with interim load reductions for each phase. The first implementation provisions begin three months after U.S. Environmental Protection Agency (USEPA) approval of the TMDL. The implementation plan also requires the Imperial Irrigation District to submit and maintain compliance with a revised Drain Water Quality Improvement Plan, to begin six months after USEPA approval of the TMDL.
The prohibition begins three months after USEPA approval of the TMDL and establishes that direct or indirect discharge of sediment will be prohibited unless the discharger is in compliance with applicable sedimentation/siltation TMDLs, has a monitoring program approved by the Colorado River Basin Water Board's Executive Officer, or is covered by Waste Discharge Requirements (WDRs) or a Waiver of WDRs.
