Hundreds of California wineries will for the first time be governed by statewide wastewater processing rules, a change from the long-held, regional approach that could increase production costs for wineries and protections for waterways while providing consistency for vintners across the state.
The move toward a statewide regulatory framework, a five-year effort championed by industry leaders, was finalized this week by the State Water Resources Control Board, which approved an order setting up guidelines for wastewater processing at most of the more than 3,600 bonded wineries in the state.
The new order promises to bring at least 1,500 of those wineries into a regulatory framework for wastewater disposal for the first time, leading to extra compliance costs. But it also provides flexibility for how, and when, those wineries will be subject to rules meant to safeguard waterways and groundwater from harmful contaminants, including excess nitrogen, salinity and other compounds that deplete oxygen levels.
“I think it was the perfect example of a compromise,” said Don McEnhill, head of the Sonoma County-based group Russian Riverkeeper.
