.The IR Program is the DoD's restoration program under DERP to identify, investigate, and clean up contamination at active/operating sites. The IRP focuses on cleanup of contamination associated with past DoD activities. SARA Section 211 and EO 12580 require that the IR Program be conducted in a manner consistent with CERCLA Section 120. The Navy/Marine Corps Installation Restoration Manual provides IR Program policy, guidance, and other information to be used to move an IR site through identification, investigation, and, if necessary, through cleanup and closure. ERAs are discussed in Section 5.9 of the manual, which may be viewed at https://enviro.nfesc.navy.mil/erb/ .
