- 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;
- Fuel storage tanks; and
- Sources exempt under S.C. Regulation 61-62.1, Section II(B).

Criteria
Registration Permit
- The plant is portable*.
- The equipment processes nonmetallic minerals only.
- The owner/operator shall operate a wet suppression system except as necessary for elevated material moisture content (i.e. rainfall).
- The equipment is not being used at the site of an existing facility, in support of the existing facility’s primary air-permitting operation, in such a way that the facility’s production capacity will be increased.
- The equipment is not operated at any one site for 12 months or more. A site is one or more contiguous or adjacent properties that are under common control.
- The equipment is powered by electricity or diesel engines.
- The diesel engines are fired on low sulfur (500 ppm or less) diesel/No. 2 fuel oil.
- 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 facility is subject to 40 CFR Subpart OOO and the requirements of an initial performance test, the performance test will be required to be submitted within the allotted timeframe detailed within the Subpart. Please note that out-of-state initial performance tests will be accepted so long as they use the method described within the Subpart.
*For 40 CFR 60 Subpart OOO applicability portable means any processing equipment that is mounted on any chassis or skids and may be moved by the application of a lifting or pulling force. In addition, there shall be no cable, chain, turnbuckle, bolt or other means (except electrical connections) by which any piece of equipment is attached or clamped to any anchor, slab, or structure, including bedrock that must be removed prior to the application of a lifting or pulling force for the purpose of transporting the unit. Any equipment indicated as portable shall not be attached or clamped by cable, chain, turnbuckle, bolt or other means (except electrical connections) to any anchor, slab, or structure, including bedrock.

Application/Forms
If operations, normally 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.
