§ 3938. Total Maximum Daily Load for Bacteria During Dry Weather at Santa Monica Bay Beaches.
This basin plan amendment establishes a Total Maximum Daily Load (TMDL) for bacteria for Santa Monica Bay Beaches for summer (April to October 31) and winter (November 1 to March 31) dry weather periods. The TMDL: (1) establishes the loading capacity of the bay beaches as the maximum densities of the four bacterial indicators (total coliform, fecal coliform, enterococcus, and total coliform when fecal-to-total ratio exceeds 0.1) specified in the basin plan as bacteriological water quality objectives for marine water having a water contact beneficial use designation; (2) specifies the maximum number of daily and weekly sampling days per dry period which each of the 67 existing shoreline monitoring stations may exceed any singe sample maximum density water quality objective (no days of exceedance are allowed at any station during the summer dry weather period); (3) provides that all responsible jurisdictions and agencies within a subwatershed are jointly responsible for complying with the allowable number of exceedance days for each associated shoreline monitoring site; (4) establishes zero exceedance days during summer and winter dry weather for the two Publicly Owned Treatment Works discharging into Santa Monica Bay; (5) specifies that the samples are to be collected from the wave wash (the compliance point); and, (6) specifies that the allowable exceedance days, and the geometric bacteria density means (specified in the basin plan as bacteriological water quality objectives) must be achieved within three years for the summer dry weather period and within six years for the winter dry weather period.
The amendment identifies the principal regulatory mechanisms to be used to implement the TMDL as the Los Angeles County Municipal Storm Water NPDES permit, the Caltrans Storm Water Permit, any future Phase 2 Municipal Storm Water NPDES permits within the Santa Monica Bay watershed management area, the General Industrial Stormwater Permit, the General Construction Stormwater Permit, the two NPDES permits for the POTWs, and the authority vested in the Executive officer by Water Code section 13267.
