The state Liquor and Cannabis Board licenses marijuana growing and processing operations, but other environmental regulations may potentially apply, such as:
- Air quality permitting
- State Environmental Policy Act (SEPA)
- Waste management
- Water quality (Wastewater discharge permitting)
- Water right permitting (depending on the size of the operation)
In addition to the information provided here, we recommend you read Regulatory Guidance for Cannabis Operations before you get started.
Some regulations are site-specific
The design and location of your intended project can significantly influence the viability of your marijuana growing or processing operation. For example, marijuana growing is prohibited in some areas of the state due to local ordinances or federal policy.
The need for permits and authorizations for a project depend on zoning rules, location, and operation details. You might want to ask what approvals are needed through your county or city permitting offices.
