Cal. Code Regs. tit. 23 § 3990
On February 10, 2010, the San Diego Regional Water Quality Control Board (San Diego Water Board) adopted Resolution No. R9-2010-0001, an amendment to the Water Quality Control Plan for the San Diego Region (Basin Plan) that incorporates Revised Total Maximum Daily Loads (TMDLs) for Indicator Bacteria, Project I -- Twenty Beaches and Creeks in the San Diego Region (including Tecolote Creek). The State Water Resources Control Board approved this amendment under Resolution No. 2010-0064 on December 14, 2010.
The purpose of these TMDLs is to restore and protect the recreational beneficial uses of the receiving waters of 12 Pacific Ocean shoreline segments, 2 creek mouths, and 6 creeks. The numeric targets for these TMDLs include the recreational water contact beneficial use water quality objectives for total coliform, fecal coliform, and Enterococcus indicator bacteria prescribed in the Basin Plan, and allowable wet weather and dry weather exceedance frequencies.
The TMDLs will be implemented primarily by reissuing or revising the existing National Pollution Discharge Elimination System (NPDES) waste discharge requirements for the Phase I and Caltrans municipal separate storm sewer systems (MS4s). The Phase I and Caltrans MS4s are required to meet and maintain the water quality objectives in the receiving waters and achieve the TMDLs within the compliance schedules prescribed in the amendment. Other discharges identified as significant sources of bacteria (e.g., agriculture) will also be required to meet and maintain the water quality objectives in the receiving waters. Future actions that may be implemented, as necessary, by the San Diego Water Board include issuing investigative orders, enforcement actions, conditional waivers, and/or waste discharge requirements, as well as developing subsequent Basin Plan amendments to refine the provisions of these TMDLs. The San Diego Water Board will initiate a Basin Plan amendment project to revise the requirements and/or provisions for implementing these TMDLs within 5 years from the effective date of this Basin Plan amendment, unless insufficient data exist to support the initiation of a Basin Plan amendment.
