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:

• carbon monoxide (CO)
• lead (Pb)
• nitrogen dioxide (NO₂)
• ozone (O₃)
• particulate matter 2.5 (PM_2.5)
• particulate matter 10 (PM₁₀), and
• sulfur dioxide (SO₂)

DEC also prepares SIPs and/or State Plans for:

• Haze and visibility
• Select regulatory SIP revisions
• Source-specific NO_x and volatile organic compounds (VOC) reasonably available control technology (RACT) determinations
• Large municipal waste combustors
• Existing sewage sludge incineration units
• Municipal solid waste landfills

DEC solicits comments from the public on all proposed SIPs before submitting them to EPA for approval. EPA maintains a status of NY designated areas, status of SIP required elements for NY designated areas, areas of the country that meet or violate NAAQS, and technical air pollution resources (leaves DEC website).

Most recent DEC SIP-related actions are available below. Large appendices are available upon request. Federal Register links leave DEC's website. Please contact us for additional information.
