General Waste Discharge Requirements for Vineyards Discharges in the Napa River and Sonoma Creek Watershed

Present Land Use
Mainly Agriculturally Zoned Land

Document Description
The proposed General Waste Discharge (WDRs) would regulate discharges from vineyards in the Napa River and Sonoma Creek watersheds. The General WDRs would apply to a group of new and existing vineyards (including replants), based on eligibility criteria described in the Notice of Preparation and attached Initial Study. The eligible vineyards would be required to 1) submit a Notice of Intent to comply, 2) prepare a Farm Water Quality Plan that identifies potential sediment sources and management practices to reduce those discharges, 3) implement the chosen management practices, and 4) submit an annual compliance report that would identify what actions were taken to control sediment discharges. The General WDRs would regulate discharges in order to achieve the performance standards for sediment and storm runoff set forth in the sediment Total Maximum Daily Loads (TMDLs) for Napa River and Sonoma Creek with the overarching goals of reducing nonpoint source pollutant discharges from vineyards and protecting and enhancing beneficial uses, including the protection of anadromous fish habitat.
