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.
