Temporary Crushing and Screening Operations

Registration permits are issued to sources where equipment similarities and simplicity remove the need for in-depth site-specific review. Additionally, these permits contain the same emission limits and monitoring requirements as the construction and operating permit for that source category.

Advantages to Registration Permits

  • A standardized permit providing consistency
  • Dual permitting process construction and operating permit combined
  • No construction permit P.E. signature required for registration permits
  • Simplified application and permit issuance
  • Flexibility to construct or modify equipment without a construction permit
  • Pre-determined equipment and emission limit for specific Permit categories

Existing permitted and new sources may request coverage under a registration permit if the permit criteria are met. The BAQ will grant the registration permit to your facility upon your certifying qualification for and agreeing to the conditions and terms of the registration permit applicable to similar sources. Your facility will be subject to enforcement action for operation without a valid permit if the facility is later determined not to qualify for the conditions and terms of the registration permit.

Below is a description of each of the registration permits, a link to the list of the current facilities that have been granted coverage, a copy of each registration permit, and the associated criteria, forms, and other information for each registration permit.

Temporary Crushing and Screening Operations

A qualifying temporary nonmetallic mineral crushing and screening operation may be eligible to receive a registration permit. A temporary crushing and/or screen operation is comprised of one or any combination of the following: crushers that reduce the size of nonmetallic mineral material by means of physical impaction upon the material (including but not limited to jaw, cone, hammermill, or impactor), screens that separate material according to size using mesh screens, conveying equipment that transports material from one piece of equipment or location to another location (including but not limited to feeders or belt conveyors), diesel engines or electric motors to power process equipment, and fuel storage tanks.

Criteria:
  1. The owner/operator of the facility has submitted a timely and complete application for coverage under this registration permit to the Department.
  2. The equipment processes nonmetallic minerals only.
  3. Wet suppression is always used during operation.
  4. The equipment is not being used at the site of an existing facility, in support of the existing facility's primary air-permitted operation.
  5. The equipment is not operated at any one site for more 12 months. A site is one or more contiguous or adjacent properties that are under common control.
  6. The equipment is powered by electricity or diesel engines.
  7. The diesel engines are fired on low sulfur (500 ppm or less) diesel/No. 2 fuel oil.
  8. The diesel engines are certified by the manufacturer to meet EPA's nonroad diesel engine emission standards/tiers (40 CFR 89 and 1039).

If the operations covered by construction permits are located in one of the eight coastal counties of the Coastal Zone under DHEC-OCRM's jurisdiction (Beaufort, Berkeley, Charleston, Colleton, Dorchester, Georgetown, Horry and Jasper), then a coastal zone consistency certification may be required.
