The purpose of this Part is to require owners and operators of air contamination sources to obtain a permit or registration from the department for the construction and operation of such sources.

This Part applies throughout New York State. Except as specifically described in Subpart 201-3 of this Part, owners and operators of air contamination sources must comply with this Part. Owners or operators of major stationary sources subject to Subpart 201-6 of this Part must obtain a title V facility permit. Owners or operators of other emission sources must either register, pursuant to Subpart 201-4 of this Part, or obtain a State facility permit pursuant to Subpart 201-5 of this Part. Owners or operators of emission sources subject to applicable requirements, or the requirement to obtain a title V facility permit, may request limitations on such source's potential to emit regulated air pollutants in accordance with Subpart 201-4 or 201-7 of this Part, in order to avoid such applicable requirements. Subpart 201-8 of this Part provides for the issuance of general permits for stationary sources subject to this Part, except for affected sources under the Federal Acid Rain Program, unless otherwise provided in regulations promulgated under title IV of the act.
