1. Facility Accidental Release Policy
The owners, management, and employees of The McGregor Company along with the crew of the Prairie facility located at Rural Route 1, Nez Peirce, Idaho 83543 are committed to the prevention of any accidental release of anhydrous ammonia. If an accidental release should occur, the McGregor Company and the Prairie retail facility are prepared to work with the local fire department, or any other authorities to mitigate any release and minimize the impact of the release to people and the environment. A detailed emergency response plan has been developed and will be implemented in the event of an accidental release.

o Anhydrous ammonia is received, stored, and distributed as an agricultural grade fertilizer to local f
o Anhydrous ammonia is received by truck and stored in one above ground tank(s). The maximum amount of anhydrous ammonia handled is 130,000 lbs.
3. The Worst-Case Release Scenario and Alternative Release Scenario
a. Anhydrous Ammonia Worst-Case and Alternative Release Scenarios
The worst-case release scenario involves the failure of the largest storage tank when filled to 85% capacity as limited by regulations. The scenario at this facility would release 130,000 pounds of anhydrous ammonia. The distance to the endpoint (the point of dispersion to 200ppm) is 1.12 miles. This figure comes from TFI's DEGADIS model.
The alternative release scenario, is based on the most likely potential incident that might occur at this facility. We used the scenario that a 2" transfer hose would break and release 11,908 pounds of anhydrous ammonia for two minutes. The distance to the endpoint (point of dispersion to 200 ppm) is 0.56 miles. This figure comes from TFI's DEGADIS model.
