BRAC Summary: In October 1992, the Rocky Mountain Arsenal National Wildlife Refuge Act, Public Law 102-402, was passed and signed by then President George H. W. Bush. It stipulates that the majority of the site will become a National Wildlife Refuge under the jurisdiction of the Fish and Wildlife Service when the environmental restoration is completed. Currently, there are no chemicals or chemical weapons produced or stored at the Arsenal and the site s only mission is to complete the safe cleanup and continued transition to one of the largest, urban national wildlife refuges.
