326 IAC 1-2-55 "Potential emissions" defined

Sec. 55. Emissions of any one (1) pollutant which would be emitted from a facility if that facility were operated without the use of pollution control equipment unless such control equipment is (aside from air pollution control requirements) necessary for the facility to produce its normal product or is integral to the normal operation of the facility. Potential emissions shall be based on maximum annual rated capacity unless hours of operation are limited by enforceable permit conditions. Potential emissions from a facility shall take into account the hours of operation per year and shall be calculated according to federal emission guidelines in AP 42-most recent edition-Compilation of Air Pollution Factors, or calculated based on stack test data or other equivalent data acceptable to the commissioner.
