The Environmental Protection Agency (EPA) is taking final action to approve the Missouri Department of Natural Resource's (MoDNR's) request for delegation of a partial Clean Air Act (CAA) Risk Management Program (RMP) for agricultural anhydrous ammonia facilities in the State of Missouri. The EPA retains authority for any anhydrous ammonia that does not meet the definition of agricultural anhydrous ammonia at these facilities, the RMP for all other regulated chemicals that may be present at these facilities, and for the RMP generally in Missouri for all other facilities.
