The Cannabis Cultivation Waste Discharge Regulatory Program addresses water quality impacts from cannabis cultivation and associated activities on private property in the Central Valley Region.
The program is designed to meet the requirements of the Central Valley's Basin Plans, the California Water Code, and the Clean Water Act. The Water Boards are the principal state agencies with primary responsibility for the coordination and control of water quality. Nonpoint source (NPS) pollution, also known as polluted runoff, is the leading cause of water quality impairments in the Central Valley Region. Many streams in the Central Valley Region are impacted by excess sediment, nutrients and elevated temperatures; and illegal surface water diversions intensify these water quality impacts. The Cannabis Cultivation Waste Discharge Regulatory Program has three main components: A General Order for Discharges of Waste Associated with Medicinal Cannabis Cultivation, Enforcement, and Education and Outreach.
