Cal. Code Regs. tit. 23 § 3989.9
Through Regional Water Board Resolution R9-2008-0027, adopted on June 11, 2008, the San Diego Regional Water Quality Control Board amended the Water Quality Control Plan for the San Diego Region (Basin Plan). On June 16, 2009, the State Water Resources Control Board (State Water Board) approved this amendment under Resolution No. 2009-0053. This Basin Plan amendment incorporates Total Maximum Daily Loads (TMDLs) for indicator bacteria in Baby Beach in Dana Point Harbor and Shelter Island Shoreline Park in San Diego Bay.
The numeric targets for these TMDLs were set equal to the recreational water contact beneficial use water quality objectives for total coliform, fecal coliform, and Enterococci indicator bacteria prescribed in the Basin Plan. Specific segments of San Diego Bay and Dana Point Harbor in the San Diego Region were placed on the List of Water Quality Limited Segments because levels of total coliform, fecal coliform and/or Enterococci at those locations exceeded water quality objectives for water-contact recreation (REC-1) beneficial use.
Since the numeric targets in the TMDLs are equal to the water quality objectives for total coliform, fecal coliform, and Enterococci bacteria, attainment of the TMDLs will ensure attainment of these water quality objectives. Applicable National Pollutant Discharge Elimination System permit requirements for municipal storm water discharges will be re-issued or revised to include requirements that will implement the TMDLs.
