Businesses that emit pollutants into the air need permits from the New York State Department of Environmental Conservation. Facilities that emit at low levels must register as an Air Facility.
|Pollutant||Air Facility Registration||State Facility Permit|
||emits less than 12.5 tons per year (tpy) of either||emits more than 12.5 tpy of either|
||emits less than 50 tpy of any||emits more than 50 tpy of any|
||emits less than 5 tpy of any one HAP and less than 12.5 tpy total of any combination of HAPs||emits more than 5 tpy of any HAP or more than 12.5 tpy in combination of HAPs|
