Pursuant to a congressional request, GAO reviewed the cleanup program for the Rocky Mountain Arsenal, focusing on the: (1) status of cleanup efforts; (2) completion plans for the cleanup; and (3) cost-sharing plans between the Army and an oil firm that leased a portion of the Arsenal.<p/>GAO found that: (1) installation restoration efforts over the past two decades have been hampered by prolonged and extensive disagreements over costs and alternative remedies; (2) the Arsenal's study phase has cost over $354 million for over 400 studies, primarily due to the large volume of lawsuits, formal disputes, and other disagreements; (3) although final cleanup has not begun, the Army and the oil company have spent about $316 million to mitigate the most critical threats at the Arsenal; (4) a conceptual agreement signed by six key parties in June 1995 should resolve the most significant issues and pave the way for a final settlement in 1996; (5) the Army and the oil company estimate that the final cleanup plan will cost $2.1 billion and will be primarily accomplished by 2012, although groundwater treatment and monitoring will continue for at least 30 years; (6) cost estimates and cleanup dates have changed significantly over the years, and current estimates may be optimistic because of such uncertainties as the impact of budget limitations, cleanup complications, and evolving standards; and (7) the cost-sharing agreement between the Army and the oil company calls for the oil company's share to decrease on a sliding scale from 50 percent to 20 percent as cleanup costs increase. https://www.govinfo.gov/content/pkg/GAOREPORTS-NSIAD-96-32/html/GAOREPORTS-NSIAD-96-32.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-NSIAD-96-32/pdf/GAOREPORTS-NSIAD-96-32.pdf GAO/NSIAD-96-32 https://www.govinfo.gov/app/details/GAOREPORTS-NSIAD-96-32 Letter Report GAO/NSIAD-96-32; Environmental Cleanup: Progress in Resolving Long-Standing Issues at the Rocky Mountain Arsenal; Cost sharing (finance) Pollution control Obsolete facilities Military facilities Atomic energy defense activities Weapons industry Hazardous substances Waste treatment Waste disposal Environment evaluation EPA National Priorities List Colorado Title 42 Section 6901 Title 42 Section 9601 42 U.S.C. 6901 42 U.S.C. 9601
