Dumas Coop - Dumas Texas - Executive Summary
1. Facility Policy for Accidental Release Prevention and Emergency Response |
The Dumas Coop Directors, Management, and employees have a strong commitment to providing a safe and healthful workplace and business for all employees, customers, owners, and to the community. These policies are set forth in a policy manual and are provided and explained to each employee prior to an initial assignment. The policies are reviewed periodically and revised and updated as necessary to reflect changes in policy, facilities, processes, regulations, safety requirements, or as new information becomes available.
The Coop is committed to the prevention of accidental releases of anhydrous ammonia and other hazardous chemicals. In the event that an accidental release does occur, the company is prepared to work with the local fire department and/or designated contractors and local authorities to mitigate the release and minimize the impact of the release on the facilities, personnel, and to the commu
nity and environment.
2. Facility Information
The primary activity of Dumas Coop is the purchase, receipt, storage, and sale of grains. Secondary activities include the storage, and sale of some farm inputs and supplies, which include: fertilizers, herbicides, pesticides, equipment, feed, and other farm supplies.
Anhydrous Ammonia is received by transport truck, unloaded into storage tank(s), then distributed seasonally to farm wagons for sale and delivery to local farmers, where it is used as fertilizer to crops such as wheat, corn, and milo.
The maximum quantity stored at Dumas Coops Dumas, Texas, facility is 203,057 lbs. in 30,000 gal. capacity and 12,000 gal. capacity storage tanks. The maximum quantity handled at any one time would be the unloading of a transport truck holding 50,000 lbs. to a storage tank.
3. Worst Case and Alternative Case Release Scenarios
(a) The worst case release scenario would be the release of the total contents of the largest storage tank wi
thin a 10 minute time period. The maximum quantity released would be 145,041 lbs., which represents the volume of the storage tank at 85% capacity, which is limited by regulation due to the expansion of anhydrous ammonia from changes in ambient temperatures. The distance to the endpoint of dispersion under an atmospheric stability class F in an urban environment has been determined to be 4.2 miles.
(b) The alternative release scenario based on the five year accident history and reports of industry incidents, is a release from a break in a transfer hose. The quantity released would be 2,943 lbs. and the distance to the endpoint for a 1 minute release under an atmospheric stability class D in an urban environment has been determined to be 0.28 miles.
4. The Accidental Release Prevention Program
The facility has implemented the provisions of "Safety Requirements for the Storage and Handling of Anhydrous Ammonia, K61.1-1989 published by the American National Standards Institute a
nd the OSHA standards published in 29CFR 1910.111 "Storage and Handling of Anhydrous Ammonia".
5. Five Year Accident History
