Abrasive blasting is defined as the cleaning or preparation of a surface by forcibly propelling a stream of abrasive material against a surface. "Sandblasting" is also a term that describes this activity and for all purposes means the same as abrasive blasting. Confined abrasive blasting is conducted inside a permanent building. It may require the installation of a high efficiency dust collector device (e.g. a fabric or cartridge filter) in order to comply with Best Available Control Technology requirements.
Particulate emissions from abrasive blasting operations can be a significant source of air pollution. To address this activity, the California Air Resources Board (ARB) adopted air pollution standards and requirements that apply to abrasive blasting operations, of which the District enforces. These standards are found in Title 17 of the California Code of Regulations, sections 92000 through 92520. The general provisions in §92500 require abrasive blasting activities to be conducted within a permanent building. Only under special conditions may abrasive blasting be conducted outdoors.
Who Needs a Permit?
- A permit is required for all confined abrasive blasting operations.
- Non-electric compressors (i.e. combustion engines) will be permitted with the abrasive blasting unit.
- One permit will be required for those abrasive blasting booths vented to a single air pollution control device serving only one booth which vents into the work area by the booth, where the total internal volume of the blast section is less than 3 cubic meters (106 ft3). All other units will require a separate permit for the air pollution control device.
Permit Fees
Abrasive Blasting Units Using a Compressor Powered by an Internal Combustion Engine
New Installations:
For modifications of permitted equipment resulting in an increase in the engine's horsepower, 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.
For modifications resulting in no increase in the engine's rated horsepower, the fee shall be based on Rule 301, Section 306.2.
Abrasive Blasting Units Using a Compressor Powered by an Electric Motor
New Installations:
For modifications of permitted equipment resulting in an increase in the horsepower of the compressor's electric motor, the fee is assessed in accordance with Rule 301, Section 308.2, based on the incremental increase in horsepower resulting from such change.
For modifications resulting in no increase in the horsepower of the compressor's electric motor, the fee shall be based on Rule 301, Section 306.2.
Permit Application Completeness Determination
An application will not be accepted for processing until it is deemed complete. The following will be required in order for the Sac Metro Air District to make a completeness determination.
Completed application Forms G100, G101, and CB100 with the original signature of the owner/proprietor or responsible officer of the company. For units using an air compressor powered by an internal combustion engine (a non-electric air compressor), also submit forms ICE100 and HRA100.
Applicable permit fee in accordance with Rule 301.
Any additional information that may be requested in order to perform a health risk assessment or to better understand the process or the applicability of regulations.
