Proposed Statewide General Waste Discharge Requirements (WDRs) for Wineries

The State Water Board is developing General WDRs for winery process water treatment systems (Winery Order) that addresses land discharge of process water from wineries, grape juice storage facilities, and wine distillation facilities (hereafter collectively referred to as wineries). The Winery Order will be applicable statewide and is intended to streamline and improve permitting consistency.

As part of the development process, the State Water Board will hold stakeholder outreach meetings to receive feedback. Meetings will be scheduled in wine producing areas of the state. This website will be updated with meeting dates, times, and locations as meetings are scheduled.
