Poag Grain, Inc., Verden, Oklahoma - Executive Summary
The owners, management, and employees of Poag Grain, Inc. are committed to the prevention of any accidental releases of anhydrous ammonia. The safety of all employees, citizens, and neighbors is our highest priority. If an accidental release should occur, this facility is prepared to work with the local fire departments, the Grady County LEPC, or any other authorities, to mitigate any release and minimize the impact of the release to people and the environment. |
The primary activity at the facility is a retail location for farm and ranch supplies, as well as the receiving of farmer produced grain. Anhydrous ammonia is received by truck, stored, and sold to farmers for crop production nutrients. The farmer transports his anhydrous ammonia from our facility to his by utilizing a nurse tank that is pulled behind a pickup or tractor.
The maximum amount stored in the 12,000 gallon storage tank is 56,078 pounds and in the 18,000 gallon storage tank is 84,118 pounds. The
maximum amount stored in our large nurse tanks is 6,612 pounds and 4,673 pounds in the smaller ones.
The worst case release scenario would be the total release of the contents of the largest storage tank in a ten minute period, despite the presence of the installed safety devices. The maximum quantity release would be 84,118 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 .89 miles.
An alternate release scenario, based on the most potential incident, is a release from a break in a transfer hose. If the safety check valve failed to operate in the event of a transfer hose rupture, approximately 11,908 pounds would be released in a 2 minute period. With a 3 meter per hour wind, the distance to the endpoint (point of dispersion to 200 ppm) is .41 miles.
There have been no accidental releases of anhydrous ammonia in the past five years that
have caused any deaths, injuries, evacuations, sheltering in place, property damage, or environmental damage.
In order to maintain our record of safety performance, this facility has: a), a written emergency action plan, in accordance with OSHA standard, 29CFR 1910.38; b), provided the state and local authorities 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 191-.120, including pre-emergency planning and employee training.
Safety improvement is an on-going process at the facility. Periodic evaluations are performed to assess the maintenance of safe conditions. If these evaluations point to conditions that can be improved, this facility is committed to make conditions safer when possible.
