Risk Management Plan Executive Summary Clean Air Act Amendment, Section 112r Patrons Mercantile Co-op ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES The owners, management and employees of Patrons Mercantile Co-op are committed to the prevention of any accidental release of anhydrous ammonia. Patrons Mercantile Co-op policy is to adhere to all applicable Federal and State rules and regulation in order to: 1. Prevent unnecessary human exposure, 2. Reduce the threat to employees health, and 3. To reduce the threat to nearby members of the community. Safety depends upon the manner in which an accidental release is handled, combined with the safety devices inherent in the design of the operation, the safe handling procedures used and the training of personnel. Patrons Mercantile Co-op complies with the provision of "Safety Requirements for Storage and Handling of Anhydrous Ammonia, K-61-1", published by The American National Standards Institute, Inc., and the standards of the U.S. Occupational Safety and Health Administration (OSHA), 29 CFR 1910.111, "Storage and Handling of Anhydrous Ammonia". Patrons Mercantile Co-op emergency response plan includes procedures for notification of the local fire authority, the LEPC and any potentially affected neighbors. STATIONARY SOURCES AND REGULATED SUBSTANCES Anhydrous Ammonia At this facility, anhydrous ammonia is stored and distributed for resale to farmers and other customers. Anhydrous ammonia is received by truck, and stored in a 18,000 gallon tank. The anhydrous ammonia is distributed for direct application. The maximum amount of anhydrous ammonia that can be stored in the 18,000 gallon storage tank at this facility is 71,500 pounds (18,000 gallon tank times 4.67 pounds/gallon times 85%). RELEASE SCENARIOS Anhydrous Ammonia Worst case scenario - Failure of the 18,000 gallon tank when filled to 85% capacity would release 71,500 pounds. The anhydrous ammonia would be released as a gas over a 10 min ute period (7150 pounds per minute). The distance to the endpoint under urban conditions using the RMP Comp model (toxic endpoint is 0.14 mg/L) is 3.1 miles. Alternate Scenario - A hose breaks resulting in a release of 11,908 pounds. The release is stopped through human intervention in 2 minutes (5954 lbs/min). The distance to the endpoint under urban condition is 0.5 miles. GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND THE SPECIFIC PREVENTION STEPS This distribution facility complies with EPA's Accidental Release Rule and with all applicable state codes and regulations. The anhydrous ammonia facility has implemented the provision of "Safety Requirements for Storage and Handling of Anhydrous Ammonia, K-61.1", published by The American National Standards Institute, Inc., and the standards of the U.S. Occupation Safety and Health Administration (OSHA), 29 CFR 1910.111, "Storage and Handling of Anhydrous Ammonia".
