State Implementation Plans and State Plans

A State Implementation Plan (SIP) is a collection of regulations and documents used by NYS to reduce air pollution in areas that do not meet the National Ambient Air Quality Standards (NAAQS) (leaves DEC website). NAAQS are required by the Clean Air Act and are set by EPA for six principle pollutants considered harmful to public health and the environment. Those pollutants are:

DEC also prepares SIPs and/or State Plans for:

DEC solicits comments from the public on all proposed SIPs before submitting them to EPA for approval. Most recent DEC SIP-related actions are available below; some large appendices are available only upon request. Please note that Federal Register links leave DEC's website. EPA's Nonattainment and Maintenance Area Dashboard (leaves DEC website) is a nationwide searchable database about nonattainment and maintenance areas for current and revoked NAAQS that includes the attainment status of New York designated areas and the status of SIP required elements for NY designated areas. Please contact us for additional information.
