Aggregate and rock crushing operations involve the handling and processing of nonmetallic mineral products for the construction industries. Nonmetallic mineral products are quarried or mined and are then transported to the processing plant for further classification and/or further size reduction. In addition, some recycled aggregate products (such as concrete and asphaltic concrete) are also processed in these plants. The processing of sand and gravel for a specific market involves the use of different combinations of washers, screens, and classifiers to segregate particle sizes; crushers to reduce oversized material; and storage and loading facilities. The various types of equipment used in these plants include: hoppers, belt conveyors, screens, scrubbers, pumps, storage bins, crushers, jigs, screws, front end loaders, scrapers, trucks, engines, and generators.
Any aggregate and rock crushing operation which would emit any pollutant, without the benefit of an air pollution control device, greater than or equal to 2 pounds in any 24 hours period.
Equipment registered under CARB's Portable
Equipment Registration Program is not required to have a permit unless it is being operated as part of a stationary source as determined by SacMetro AQMD .
Baghouses and Internal Combustion Engines:
For modifications of existing aggregate and rock crushing processes resulting in an increase in the motor horsepower of the aggregate plant, 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 aggregate plant, the applicant shall pay a permit fee based on Rule based on Rule 301, Section 306.2.
An application will not be accepted for processing until it is deemed complete. The following will be required in order for the SacMetro AQMD to make a completeness determination.
