- General Waste Discharge Requirements for Winery Process Water
- The State Water Board has prepared draft General Waste Discharge Requirements for Winery Process Water (General Order) available statewide to regulate the discharges to land of winery process water with a potential threat to water quality. The General Order will cover discharges of winery process water to land starting at 10,000 gallons per year and can cover larger discharges (e.g., 100,000,000 gallons per year). The General Order includes minimum treatment levels, monitoring, and management practices based on the number of gallons of winery process water discharged per year. The General Order also requires compliance with regional water quality control board water quality control plans (Basin Plans), applicable statewide water quality plans or policies, and mitigation measures required by this General Order and future site-specific CEQA evaluations. The General Order will be used by the regional water quality boards to streamline permitting of wineries discharging process water to land and increase water quality protection from these discharges statewide. The General Order was publicly noticed July 3, 2020 for a public comment period ending August 5, 2020.
