Risk Management Plan Executive Summary Clean Air Act Amendment, Section 112r WS AG ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES The owners, management and employees of WS AG are committed to the prevention of any accidental release of anhydrous ammonia. WS AG 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. WS AG 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". WS AG 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. This anhydrous system was built in the spring of 1998. Inspections were performed by the Department of Commerce on 4/2/98 prior to operation. Anhydrous ammonia is received by truck, and stored in 2 -12,000 gallon tanks. The anhydrous ammonia is distributed for direct application. The maximum amount of anhydrous ammonia that can be stored at this facility in one of the 12,000 gallons tanks is 47,700 pounds (12,000 gallon tank times 4.67 pounds/gallon times 85%). RELEASE SCENARIOS Anhydrous Ammonia Worst case scenario - Failure of the 12,000 gallon tank when filled to 85% capacity would release 71,500 pounds. The anhydr ous ammonia would be released as a gas over a 10 minute 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 2.6 miles. The estimated population within the 2.6 miles was calculated by using the Landview Software. Landview estimated that there would be 1494 persons within the 2.6 miles. Due to the fact that that the Village of Darlington is totally encompassed within the 2.6 miles we believe that the true number to be closer to 2400 persons. 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. Landview estimates that there is 19 persons within the = mile. GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND THE SPECIFIC PREVENTION STEPS This distribution facility complies with EPA's Accidental Release Rule and with all applicab le 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". FIVE-YEAR ACCIDENT HISTORY There have been no accidental releases of anhydrous ammonia in the pas 5 years that have caused any death, injuries, or significant property damage at the facility; nor to our knowledge, have resulted in off site deaths, injuries, evacuation, sheltering in place, property damage or environmental damage. There have been no accidental releases of propane in the past 5 years that have caused any deaths, injuries, or significant property damage at the facility; nor to our knowledge, have resulted in off site deaths, injuries, evacuations, sheltering in place, property damage or environme ntal damage. EMERGENCY RESPONSE PROGRAM This facility emergency response program is written in accordance with OSHA standard 29 CFR 1910.38. WS AG has discussed this program with the LEPC and local fire department. A representative of the local fire department has inspected the site. PLANNED CHANGES TO IMPROVE SAFETY Safety improvement is an on-going process at the facility. Periodic evaluations are performed to assess the maintenance of safe conditions. There are no additional specific safety recommendations for implementation. |
