Cannabis Operations may consist of cultivation-only operations, cannabis manufacturing or operations that combine both cultivation and manufacturing. Cannabis Manufacturing is subject to District Rule 201 -- General Permit Requirements. In most cases, cannabis cultivation-only is considered agricultural, not subject to a District permit and must utilize utility power or employ electrical generation technologies that are Distributive Generation certified with CARB. Other state and local regulations may apply to cultivation-only operations. Be advised Department of Cannabis Control and City of Sacramento’s definitions or categorization of operation type may differ from those utilized by the Sac Metro Air District. Additional information about regulations and permit requirements for cannabis operations is available on the District's Cannabis Operations Matrix: (Link). Please contact District Staff with any questions you may have regarding your facilities specific equipment and permitting requirements.
Who Needs a District Permit?
Cannabis Manufacturing Operations:
Mechanical Processes (sifting, squeezing, or screening) that have the potential to emit Particulate Matter (PM) emissions greater than 2 pounds per day.
Solvent Extraction Processes (CO2 or Ethanol) or Solvent Cleaning Operations that use and emit solvents in amounts that exceed 2 pounds per day.
Odor/VOC control device venting cannabis manufacturing operations that is necessary to prevent a nuisance; otherwise, if not needed to prevent a nuisance, the odor/VOC control device will be included on other cannabis processing permits.
Internal combustion engines (prime power, back-up power, or considered part of a process):
if the engine is rated at 50 brake horsepower or less and is considered part of a process that would otherwise require a permit, or
if the engine is rated at greater than 50 brake horsepower.
Combustion gas turbines (prime power, back-up power, or considered part of a process):
if the turbine is rated at 3,000,000 BTU's per hour or less and is considered part of a process that would otherwise require a permit, or
if the turbine is rated at greater than 3,000,000 BTU's per hour.
Boilers and Heaters that have an individual heat input rating or an aggregate heat input rating of 1,000,000 BTU's per hour or greater. Only boilers or heaters used in the same process will be accumulated to determine the aggregate heat input rating.
Permit Fees
New Installations:
Mechanical Processes – Use Schedule 1 (see Rule 301 Section 308.2). Fees are based on the cumulative total rated electrical horsepower of all motors in the equipment. Use the Initial Permit Fee column for new installations or equipment not previously permitted.
Solvent Extraction Processes – Use Schedule 9 (see Rule 301, Section 308.10) for an initial permit fee.
Odor/VOC control device – Use Schedule 1 (see Rule 301, Section 308.2). Fees are based on the size of the electrical motor powering the blower. Use the Initial Permit Fee column for new installations or equipment not previously permitted.
Internal Combustion Engine – Use Schedule 7 (see Rule 301, Section 308.8. Fees are based on the total rated horsepower of the engine. Use the Initial Permit Fee column for new installations or equipment not previously permitted.
Gas Turbines – Use Schedule 2 (See Rule 301, Section 308.3). Fees are based on the heat input rating of the equipment. Use the Initial Permit Fee column for new installations or equipment not previously permitted.
Boilers and Heaters – Use Schedule 2 (see Rule 301, Section 308.3). Fees are based on the heat input rating of the equipment. Use the Initial Permit Fee column for new installations or equipment not previously permitted.
Modifications:
Mechanical Processes
- For modifications of existing mechanical processes resulting in an increase in the motor horsepower of the process, the fee is assessed in accordance with fee Schedule 1 (see Rule 301, Section 308.2) based on the incremental increase in horse power resulting from such change (see Rule 301, Section 306.1).
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, but no increase or change is made to the motor horsepower rating of the process, the applicant shall pay a permit fee based on Rule 301, Section 306.2.
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, with no increase in emissions, the applicant shall pay a permit fee based on Rule 301, Section 306.2.
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, with an increase in emissions, the applicant shall pay a permit fee based on Schedule 9 (see Rule 301, Section 308.10) for an initial permit fee.
Odor/VOC control device
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, but no increase or change is made to the motor horsepower rating of the exhaust fan, the applicant shall pay a permit fee based on Rule 301, Section 306.2.
Internal Combustion Engine
- For modifications of existing internal combustion engines resulting in an increase in horsepower of the engine, the fee is assessed in accordance with fee Schedule 7 (see Rule 301, Section 308.8) based on the incremental increase in horsepower resulting from such change (see Rule 301, Section 306.1).
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, but no increase or change is made to the horsepower rating of the engine, the applicant shall pay a permit fee based on Rule 301, Section 306.2.
Gas Turbines
- For modifications of existing Gas Turbines resulting in an increase in heat input rating, the fee is assessed in accordance with fee Schedule 2 (see Rule 301, Section 308.3) based on the incremental increase in heat input rating resulting from such change (see Rule 301, Section 306.1).
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, but no increase or change is made to the heat input rating, the applicant shall pay a permit fee based on Rule 301, Section 306.2.
Boilers and Heaters
- For modifications of existing boiler or heater resulting in an increase in heat input rating, the fee is assessed in accordance with fee Schedule 2 (see Rule 301, Section 308.3) based on the incremental increase in heat input rating resulting from such change (see Rule 301, Section 306.1).
- When an application is filed for a revision of condition on a Permit to Operate or any alteration or addition, but no increase or change is made to the heat input rating, the applicant shall pay a permit fee based on Rule 301, Section 306.2.
