Fuel Combustion Operations

Facilities that only have boilers, emergency generators, and non-emergency generators (for example, peak-shaving generators), fuel storage tanks, and ethylene oxide sterilizers (hospitals) may be eligible for a general permit for fuel combustion operations. These facilities can have exempt sources as well that are not fuel combustion sources.
