The U.S. Environmental Protection Agency says EnPro Holdings Inc. will install fencing and signs warning residents and visitors of potential radiation exposure at sites in northeastern Arizona near Cameron and Tuba City. The company also will assess for radiation and conduct biological and cultural surveys ea.
The work is expected to cost $500,000 and be complete by the end of the year.
