§ 3918. Basin Plan Amendment to Establish a Total Maximum Daily Load (TMDL) and Implementation Plan for Pathogens in the Napa River Watershed.
Through Regional Water Board Resolution R2-2006-0079, adopted November 13, 2006, the San Francisco Bay Regional Water Quality Control Board amended the Water Quality Control Plan for the San Francisco Bay Region (Basin Plan). The Basin Plan amendment includes new regulatory provisions, summarized below:
1. Numeric water quality targets for the Napa River consisting of:
• Geometric mean and single sample maxima for E. coli density, Fecal Coliform densities, and Total Coliform densities. In addition, a zero discharge of untreated or inadequately treated human waste was included.
2. A TMDL for the Napa River consisting of:
• Geometric mean and single sample maxima for E. coli density, Fecal Coliform densities, and Total Coliform densities. All sources of untreated or inadequately treated human waste have an allocation of zero.
3. Allocations of the total maximum daily load among the various sources of pathogens in the Napa River watershed:
• On-site sewage disposal systems (septic systems)
• Sanitary sewer systems
• Wastewater treatment facilities
• Confined animal facilities
• Grazing lands
• Municipal runoff
• Wildlife
4. The TMDL implementation plan builds upon existing efforts and requires actions by source categories to reduce pathogen loads and achieve allocations. These actions include evaluation of operating practices, development of comprehensive and site-specific pathogen control measures, and submittal of progress reports documenting actions undertaken.
5. A plan and schedule for monitoring and evaluating progress toward meetings targets and implementing proposed actions.
