Readiness and Environmental Protection Integration, U.S. Department of Defense

About the Readiness and Environmental Protection Integration (REPI) Program

Established in 2002 as part of the Fiscal Year 2003 National Defense Authorization Act, the Department of War (DOW) Readiness and Environmental Protection Integration (REPI) Program preserves military missions by supporting cost-sharing agreements between the Military Services, other Federal agencies, state and local governments, and private organizations to avoid land use conflicts near military installations, address environmental restrictions that limit military activities, and increase military installation resilience.

The REPI Program is administered by the Office of the Secretary of War under the Assistant Secretary of War for Energy, Installations, and Environment.
