Cal. Code Regs. tit. 23 § 3968
Resolution Order No. R7-2007-0039, adopted on May 16, 2007 and revisions adopted by Resolution Order No. R7-2010-0028 on June 17, 2010 by the Colorado River Basin Regional Water Quality Control Board (Colorado River Basin Water Board), modified the regulatory provisions of the Water Quality Control Plan for the Colorado River Basin Region by establishing a Total Maximum Daily Load (TMDL) and Implementation Plan for Bacterial Indicators in the Coachella Valley Stormwater Channel. The State Water Resources Control Board approved the amendments under Resolution No. 2011-0030, on July 19, 2011.
The TMDL addresses the impairment to water quality in the Coachella Valley Stormwater Channel due to exceedences of bacteria water quality objectives. The TMDL sets numeric targets for E. coli.
The implementation plan is divided into two phases with Phase I actions being implemented within 90 days following U.S. Environmental Protection Agency (U.S. EPA) approval of the TMDL. Phase I actions will take three years to complete and will focus on monitoring and addressing bacteria associated with wastewater discharges from facilities, urban runoff, and stormwater runoff. If the water quality objectives are not achieved by the end of Phase I, Colorado River Basin Water Board staff will implement additional actions in Phase II to control pathogenic sources. Enforcement actions against violators of the TMDL may be taken in Phases I and/or II, if necessary.
