Cannabis Policy Approved and in Effect;
Live Online Cannabis Regulatory Program Portal

Welcome to the State Water Resources Control Board's (State Water Board) Cannabis Cultivation Regulatory Program webpage. On December 18, 2017 the state's Office of Administrative Law approved and put into the state's regulatory code this program, which is now in effect. The Cannabis Regulatory Program Portal is now live. Visit the Cannabis Regulatory Program's Portal to enroll for coverage under the Cannabis General Order or to file for a cannabis Small Irrigation Use Registration water right.

Background: On October 17, 2017, the State Water Board adopted the Cannabis Cultivation Policy - Principles and Guidelines for Cannabis Cultivation (Cannabis Policy) and General Waste Discharge Requirements and Waiver of Waste Discharge Requirements for Discharges of Waste Associated with Cannabis Cultivation Activities ( Cannabis General Order). The State Water Board is establishing this new regulatory program to address potential water quality and quantity issues related to cannabis cultivation and to meet the directives of Senate Bill (SB) 837 (Statutes 2016, Chapter 32, Committee on Budget and Fiscal Review) and the Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA; Senate Bill 94 [Statutes 2017, Chapter 27, Committee on Budget and Fiscal Review]).
