Risk Management Plan - Executive Summary 
 
Facility:    MFA Agri Service

1. The Facility Policy 
 
   MFA Incorporated, and the employees of the MFA Agri Service near Benton are committed to the prevention of any accidental release of anhydrous ammonia. If an accidental release should occur, the facility is prepared to work with the NBC Fire Protection District, and other authorities, to mitigate any release and minimize the impact of the release to people and the environment. 
 
2. Facility Information 
 
   The primary activity at the facility is the receiving, storage and distribution of bulk dry fertilizer and anhydrous ammonia for direct application as a crop nutrient. 
 
   The maximum quantity stored would be 140,000 pounds in our 30,000 gallon storage tank. The maximum quantity handled would be the unloading of a transport delivery truck holding approximately 50,000 pounds. 
 
3. The worst-case and a 
lternative release scenario. 
 
   a. The worst-case release scenario would be the release of the total contents of the storage tank released as a gas over 10 minutes. The maximum quantity released would be 140,000 pounds, which represents the volume of the storage tank at 85 percent capacity as limited by design standards. The distance to the endpoint (point of dispersion to 200 ppm) is 2.5 miles. 
 
   b. The alternative release scenario based on the most likely potential incident is a release from a break in a 3 transfer hose during receiving operations. This release is assumed to last approximately 2 minutes before automatic or manual shut-off stops the flow. The maximum quantity release would be 26,640 pounds. The distance to the endpoint (point of dispersion to 200 ppm) is 1.2 miles. 
 
4. The Accidental Release Prevention Program. 
 
   The facility has implemented the provisions of "Safety Requirements for the Storage and Handling of Anhydrous Ammonia, K-61.1, 1989", published by The Americ 
an 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". 
 
5. The Five-year Accident History 
 
   The following is a list of accidental releases of anhydrous ammonia in the past five years that have occurred at this facility:    
 
   8/2/97; < 100 pounds; one adjacent house was evacuated as a   
            precautionary measure.  
 
 
6. The Emergency Response Program. 
 
   The facility has; 
 
   a. a written emergency action plan, in accordance with OSHA 
      Standard, 29 CFR 1910.38; 
 
   b. provided State and Local authorities with the emergency 
      planning and community right-to-know information as 
      required under SARA Title III (EPCRA); 
 
   c. a written emergency response program, in accordance with 
      OSHA Standard, 29 CFR 1910.120, including pre-emergency 
      planning and employee training. 
 
7. Planned changes to improve safety. 
 
   Safety improvement is an on-going proc 
ess at the facility. Periodic evaluations are performed to assess the maintenance of safe conditions. There are no additional specific anhydrous ammonia safety recommendations for implementation at this time.
