Rocky Mountain Arsenal is celebrating the end of years of cleanup work to transform it from a chemical weapons-making site for the Army into a national wildlife refuge.
A ceremony Friday marks the end of major environmental cleanup work at the northeast Denver site.
It also marks the formal transfer of 2,500 acres from the Army to the U.S. Fish and Wildlife Service for the refuge, which will then cover more than 15,000 acres.
Interior Secretary Ken Salazar is among those attending the ceremony.
After World War II, Shell Chemical Co. made pesticides and other chemicals at the arsenal site until 1982. It was later designated a Superfund site before Congress in 1992 declared that it be turned into a national wildlife refuge.
