Risk Management Plan Executive Summary Clean Air Act Amendment, Section 112r Farmers Co-op Shipping & Supply Association Melrose Ammonia Plant ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES The owners, management and employees of Farmers Co-op Shipping & Supply Association are committed to the prevention of any accidental release of anhydrous ammonia. Farmers Co-op Shipping & Supply Association's policy is to adhere to all applicable Federal and State rules and regulations 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. Farmers Co-op Shipping & Supply Association complies with the provision of "Safety Requirements for Storage and Handling of Anhydrou s 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". Farmers Co-op Shipping & Supply Association's 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 is stored in a 30,000-gallon tank. The anhydrous ammonia is distributed and used for direct application to farm fields. The maximum amount of anhydrous ammonia that can be stored at this facility is 119,000 pounds (30,000 gallon tank times 4.67 pounds/gallon times 85%). RELEASE SCENARIOS Anhydrous Ammonia Worst case scenario - Failure of the 30,000-gallon tank when filled to 85% capacity would release 119,000 pounds. The anhydrous ammonia would be released as a gas over a 10-minute period (11,900 pounds per minute). The distance to the endpoint under rural conditions using RMP-Comp (toxic endpoint is 200 ppm) is 5.6 miles. Alternate Scenario - A hose breaks resulting in a release of 6000 pounds. The release is stopped through human intervention in 2 minutes (3,000 lbs/min). The distance to the endpoint under rural conditions is 1.0 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, "Sto rage and Handling of Anhydrous Ammonia".
