Assessing and Mitigating Impacts of Fine Particulate Matter Emissions (PM2.5)

Summary: Certain projects regulated by the Department of Environmental Conservation have the potential to emit fine particulate matter, or PM2.5, in quantities that could have a potential for significant adverse health and/or environmental impacts. The methodology set forth in this policy (CP-33, see Related Link at right) is consistent with the State Environmental Quality Review Act, represents a correct interpretation of its mandates, provides guidance on the project-specific assessment of fine particulate matter impacts and details when mitigation of such impacts may be necessary.
