The Army told the Nuclear Regulatory Commission it could cost $3.2 billion to clean the area for unrestricted use. All manufacturing activities ended in 1982. Soon after, Congress enacted legislation designating the RMA as a future national wildlife refuge. RMA is also one of the few sites that had a stockpile of Sarin gas (aka nerve agent GB), an organophosphorus compound. Today, the Rocky Mountain Arsenal, once some of the most contaminated land in the country, is a cleaned-up nature center. 1989The U.S. Additionally, ordnance (including incendiary munitions) was manufactured and tested, and asbestos and polychlorinated biphenyls (PCBs) were used at RMA. and help keep the future of Westword, Use of this website constitutes acceptance of our, Denver boot puts the lock on the Global Business Travel Association bash.
