The Army Corps of Engineers has agreed to pay $85,059 to settle EPA claims that it violated federal regulations meant to protect the public from hazardous chemicals at a research lab in Hanover, N.H., and it has taken action to improve the safety of its operations at the facility. EPA alleged that the Army Corps did not comply with "Risk Management Plan" regulations contained in the federal Clean Air Act in its handling of anhydrous ammonia at its Cold Regions Research and Engineering Laboratory in Hanover. This facility contains about 14,000 pounds of anhydrous ammonia in a closed-loop refrigeration process. Risk Management Plan (RMP) requirements help to protect communities, workers, and emergency responders from accidental releases of hazardous chemicals, including ammonia.
