Risk Management Plan - Executive Summary 
Facility:    MFA Anhydrous Ammonia Plant - Centralia 
Location:    1400 E. Hwy. 22, Centralia, Mo. 
Contact:     Pat Reichert 
Phone:     573-682-2157 
1. The Facility Policy 
   MFA Incorporated, and the employees of the MFA Anhydrous Plant in Centralia 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 Centralia Fire Department, 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 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 alternative  
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 26,638 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 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". 
5. The Five-year Accident History 
   There have been no accidental releases of anhydrous ammonia in the past five years that: have caused any deaths, injuries, or significant property damage at the facility; nor to our knowledge, have resulted in offsite deaths, injuries, evacuations, sheltering in place, property damage, or environmental damage. 
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 process 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.
