The California State Water Resources Control Board has released a final draft remand order directing the Central Valley Regional Water Quality Control Board to revise dairy water quality regulations, prompting concerns from industry groups about potential costs and operational impacts on dairy farms. The proposed changes apply only to dairies operating in the Central Valley. … The order focuses on reducing nitrate impacts to groundwater. … A key component of the proposal is a broader whole-farm nitrogen accounting system. Dairies would be required to track nitrogen generated on their operations, applied to cropland and exported off-site, with the goal of reducing nitrogen that could contribute to groundwater contamination.
