EA-1747: Final Environmental Assessment

Surface Water Configuration Project at the Rocky Flats Site, Colorado

The RFS is owned by the United States and is located in northern Jefferson County, Colorado, approximately 16 miles northwest of Denver. The RFS was formerly used to process and manufacture nuclear weapons components, but cleanup and closure of Rocky Flats by the U.S. Department of Energy (DOE) was completed in 2005. The Office of Legacy Management (LM) has jurisdiction and control of portions of Rocky Flats. The purpose of the Proposed Action is to reduce or eliminate the retention of surface water to return the RFS surface water flow configuration to the approximate conditions existing prior to construction of the dams.
