Emission Reduction Credits (ERCs)

Emission Reduction Credits (ERCs) are generated when a facility shuts down or voluntarily reduces its permitted emissions by accepting a federally-enforceable emission limit or operating condition. The ERCs can be used to offset emission increases from facilities constructing or modifying air emission sources subject to New Source Review. These provisions are described under 6NYCRR Subpart 231-10 (link leaves DEC's website).

The ERC Registry

ERCs are made available in a registry (PDF) (617 KB, 37 pages) maintained by the Division of Air's Bureau of Stationary Sources pursuant to the New York State Clean Air Compliance Act and 6NYCRR Part 231 (link leaves DEC's website). If you require a historical ERC document or the Use of ERCs Registry, please contact this office.
