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 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.
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.
