How the MDA implements NEPA


The Missile Defense Agency (MDA) conducts most of its actions on host military installations, military ranges, or other federal properties. Prior to 2010, the MDA relied on the host services’ or agency's National Environmental Policy Act (NEPA) procedures. However, the MDA established agency-specific NEPA implementing procedures and Categorical Exclusions (CATEXs) for our projects and actions, which were published in the Federal Register on Aug. 8, 2014.

- MDA's NEPA Implementing Procedures and CATEX's, Aug. 2014.

- The information that the MDA assembled while developing our CATEXs is described in the Administrative Record for Missile Defense Agency Proposed Categorical Exclusions, Oct. 2013.

- The Council on Environmental Quality’s (CEQ) Aug. 7, 2014 determination that MDA’s NEPA Implementing Procedures and Agency-specific CATEXs were in conformance with NEPA and the CEQ regulations is available here (Federal Register 2014-18730).
