Background Document General Air Quality Permit for New …
As there are no particulate emission factors for wet sand and gravel processing, no upper throughput limit for sand processing can be calculated. The raw materials limits in the General Permit, which are based on the particulate emissions from a specific configuration of rock crushing equipment, have been used for sand and gravel plants.
