Willard Agri-Service of Frederick, Inc. - Executive Summary

| Accident History | Chemicals | Emergency Response | Registration | Source | Executive Summary |

 1. The facility policy 
The owners, management, and employees of Willard Agri-Service are committed to the prevention of any accidental releases of ammonium hydroxide.  If an accidental release would occur, the facility is prepared to work with the Frederick County Emergency Response Coordinator, Fire and Police Departments, or 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 storage and blending of fertilizers. 
      - Ammonium Hydroxide is stored in two separate 22,000 gallon tanks, which are within an enclosed dike.  The dike would allow rapid recovery of any spilled or released ammonium hydroxide liquid. 
      - The maximum quantity stored would be 330,000 pounds in our two-22,000 gallon storage tanks. 
 3. The worst-case release scenario and the alternative release scenario. 
      a. The worst-case release sce 
nario would be the release of the total contents of one of the 22,000 gallon storage tanks released as a liquid into the dike as a pool.  Ammonia gas would then vaporize from that pool for 74.5 minutes, or a lesser time for complete recovery of the liquid.  The maximum quantity released would be 165,000 pounds, which represents the volume of a 22,000 gallon storage tank.   The distance to the endpoint (point of dispersion to 200 ppm) is 0.25 miles. 
      b. The alternative release scenario, based on the most likely potential incident, is a release from a break in a transfer hose.  The distance to the endpoint (point of dispersion to 200 ppm) is 0.09 miles. 
 4. The accidental release prevention program. 
The facility has implemented an accidental release prevention program following generally accepted industry best management practices.   
 5. The five-year accident history  
There have been no accidental releases of ammonium hydroxide 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 written Emergency Action Plan with Frederick Countys Emergency Response Coordinator dated March, 1996. 
 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 ammonium hydroxide safety recommendations for implementation at this time.
