State Implementation Plans and State Plans

Pursuant to the Clean Air Act, the U.S. Environmental Protection Agency (EPA) develops National Ambient Air Quality Standards (NAAQS) for six criteria pollutants: ozone, particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead. In areas of nonattainment (i.e., where pollutant levels exceed the NAAQS), State Implementation Plans (SIPs) are developed to demonstrate that the state has appropriate program components in place, and to identify emission control programs that the state will rely on to meet and maintain the NAAQS. State SIPs must also account for pollution that contributes to visibility impairment, otherwise known as regional haze.

The New York SIP is made up of many related actions that have been taken to meet these Clean Air Act requirements, such as infrastructure assessments, attainment demonstrations, and regulations. Whenever a revision to the SIP is required, DEC solicits public comments on a proposed version before a final version is submitted to EPA.

This webpage features those proposed SIP revisions and DEC's submissions to EPA, as well as important SIP-related correspondence. Historical and proposed revisions of SIPs not included on this webpage or the SIP archive webpage are available by request via dar.sips@dec.ny.gov. New York's SIP actions are codified under 40 CFR Part 52 Subpart HH. EPA maintains a webpage summarizing New York's fulfillment of SIP requirements here: https://www3.epa.gov/airquality/urbanair/sipstatus/reports/ny_elembypoll.html
