After 23 years and $2.1 billion, the Rocky Mountain Arsenal is ready to be removed from the nation’s Superfund list of environmental disasters.
Environmental Protection Agency officials are transferring a final 2,500 acres at the 27-square-mile site to the U.S. Fish and Wildlife Service. This clears the way for the arsenal’s new incarnation as a national wildlife refuge.
U.S. taxpayers paid for the bulk of the cleanup — done by the Army and Shell Oil under a legal settlement.
For half a century, the arsenal at Denver’s northeast edge loomed as a secretive complex of more than 250 buildings with signs around it warning “Use of Deadly Force Authorized.” There, the Army made chemical weapons and later, Shell made pesticides.
Residential and commercial development gradually encroached on the site. Today, 47 bison roam, raptors circle and badgers burrow on recovering short-grass prairie 10 miles from downtown Denver.
