    Annual Emission Fees

    Air Emissions refer to air contaminants that exit a facility from a stack, vent, or fugitive source. Air emissions can be monitored by instruments continuously or by analyzing a representative sample. When emissions are voluntarily reduced, it may be possible for a facility to register Emission Reduction Credits that can be marketed. Some facilities are required to report their air emissions annually and some are subject to an annual air emissions fee.
