Fuel Combustion 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.

Fuel Combustion Operations

Facilities that have the following sources: boilers, generators (emergency and non-emergency), storage tanks, ethylene oxide sterilizer (if located at a hospital), and sources exempt as outlined in S.C. Regulation 61-62.1, Sections II(A)(1)(b) and II(B).

Emergency generators that are < 150 kilowatt rated capacity are exempt from obtaining a permit. The emergency generators are still subject to and must comply with S.C. Regulations 61-62.63 and 40 CFR 63, Subpart ZZZZ. These generators may be subject to and shall comply with S.C. Regulations 61-62.60 and 40 CFR 60, Subparts IIII and JJJJ.

Emergency generators that are > 150 kilowatt rated capacity designated for emergency use only, and are operated total of 500 hr/yr or less for testing and maintenance are exempt from obtaining a permit. These generators must have a method to record the actual hours of use such as an hour meter. The emergency generators are still subject to and must comply with S.C. Regulation 61-62.63 and 40 CFR 63, Subpart ZZZZ. These generators may be subject to and shall comply with S.C. Regulations 61-62.60 and 40 CFR 60, Subparts IIII and JJJJ.

Criteria:

The maximum size for a single boiler burning fuels other than natural gas and propane is limited to 30 million BTU/hr heat input capacity

The total capacity of all boilers on site is limited to 100 million BTU/hr heat input capacity.

Sources can only be fired on natural gas, propane, virgin No. 2 fuel oil, virgin diesel, Biodiesel that meets ASTM D6751 or any other Department approved fuels. The use of any non-specification oil, hazardous waste, or any other waste chemical as a fuel or any addition of these items to the fuel shall not be allowed.

Sulfur content of any fuel burned shall be less than or equal to 0.05% by weight.

The non-emergency generators are certified by the manufacturer to meet EPA's nonroad diesel engine emission standards/tiers.

To be exempt from modeling, non-emergency generators are limited to operating no more than 500 hours per year.

Facility wide potential to emit is less than any major source thresholds as defined in Title V and NSR.

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.
