Press release from the State Water Board…
The State Water Resources Control Board (State Water Board) fine-tuned its pioneering cannabis cultivation policy Tuesday to clarify implementation issues while ensuring growers continue to be environmentally responsible in an industry that has rapidly expanded with urban and rural grow sites throughout much of California.
The updates, focusing on four key issues – onstream reservoirs, tribal buffers, requirements for indoor cultivation sites, and winterization requirements — were incorporated into the policy to increase and simplify compliance. The policy revisions were finalized after months of feedback from stakeholders.
“The updates improve the rules that commercial cannabis growers must follow, while adhering to sound environment protection practices intended to keep waterways and lands from being contaminated, and water resources protected when there is more demand than supply,” said Eileen Sobeck, executive director at the State Water Boards.
The initial policy was approved in October of 2017 in response to Proposition 215, the Compassionate Use Act, establishing the medical cannabis industry, and Proposition 64, which legalized recreational marijuana use for adults 21 and older.
During the public comment period for the updated policy, individual and grower coalitions pointed out that certain requirements in the initial policy, especially those dealing with how grow sites were maintained or prepared during the largely dormant winter months, did not reflect the new realities of an industry that has pushed well beyond its origins along the rugged and rainy North Coast into more established farmlands of the Central Valley and Central Coast.
With the changes in place after a vote of the State Water Board at today’s meeting, the main tenets of the Cannabis Cultivation Policy remain unchanged – to protect water flows and water quality in the state’s rivers and streams. To achieve that, the policy uses a two-pronged approach – statewide requirements detailed in a water quality permit known as the Cannabis General Order, and cannabis-related water rights referred to as Cannabis Small Irrigation Use Registrations (SIUR).
Since voters approved Prop. 64 in November of 2016, the State Water Board anticipated the rapid growth of the recreational cannabis market and made good on its commitment to protect California’s waters from cannabis-related discharges, establish safeguards for riparian areas and wetlands, and protect stream flows.
Here is a summary of the four key updates:
- Onstream reservoirs: This update provides a path for cultivators with pre-existing onstream reservoirs to obtain a Cannabis SIUR water right if the reservoir meets specific conditions – it existed prior to Oct. 1, 2016, and it is determined that the removal of the reservoir and installation of off-stream storage would cause more environmental harm than continuing the use of the existing reservoir.
- Tribal buffers: Provides certain options for Native American tribes to implement cannabis cultivation activities within 600 feet of tribal lands and a 45-day period for tribes to accept, reject, or remain silent regarding a cannabis cultivation request.
- Winterization requirements: Addresses the shift of cannabis cultivation sites from remote locations in rugged terrain that pose a high threat of stormwater runoff towards flatter areas that don’t pose as serious of a runoff threat. The update allows for the Executive Officer or other designee from a Regional Water Board to authorize the use of heavy equipment for routine cannabis cultivation preparation and planting through approval of a site management plan.
- Indoor cultivation site exemptions: For indoor cultivation sites that have a building permit and certificate of occupancy for cannabis cultivation, and that discharge waste to a permitted wastewater collection system, cultivators are exempt from the riparian setback and tribal buffer requirements.
Since 2013, the State Water Board’s Office of Enforcement has worked with the North Coast and Central Valley Regional Water Boards, along with the California Department of Fish and Wildlife, to address the potentially harmful environmental impacts of cannabis cultivation. With the revised and updated Cannabis Policy, the State Water Board will continue its enforcement efforts while engaging with new cultivators to understand the regulations and help them navigate the permitting process and become compliant.
