The Indiana Department of Environmental Management (IDEM) now offers an informative Stationary Engine Requirements webpage assisting owners and operators of stationary engines to determine whether or not the engine requires an air permit or is compliant with the federal rules for reciprocating internal combustion engines located at 40 CFR 63 Subpart ZZZZ, the National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines. Stationary engines are typically found at manufacturing, agricultural, municipal utilities, hospitals, retail centers, schools, and other types of businesses.
On December 20, 2012, the U.S. Environmental Protection Agency (U.S. EPA) finalized changes to the rule (40 CFR Part 63, Subpart DDDDD and Subpart JJJJJJ) regulating existing and new industrial, commercial, and institutional boilers located at area and major source facilities. A major source emits or has the potential to emit more than or equal to 10 tons per year (tpy) of any single air toxic or more than or equal to 25 tpy of any combination of air toxics. An area source is a stationary source for hazardous air pollutants that is not a major source. The final rule applies to boilers located at major and area source facilities that burn coal, oil, biomass, or non-waste materials, and for major sources boilers over 10 MMBTU/hr heat input capacity that burn gaseous fuels (including but not limited to natural gas, process gas, landfill gas, hydrogen, LPG).
