DESCRIPTION OF THE ANHYDROUS AMMONIA STORAGE/DISTRIBUTION PLANT AND THE REGULATED SUBSTANCE HANDLED AT SWISS VALLEY FARMS COMPANY, CASCADE, IOWA:
This facility is a bulk anhydrous ammonia storage and distribution plant. The anhydrous ammonia that is stored at this facility is distributed to agricultural crop producers in the surrounding area who utilize the anhydrous ammonia for crop nutrient purposes.
The system consists of one (1) 30,000-gallon storage tank with associated piping, valves, liquid pump(s), and other miscellaneous equipment. The anhydrous ammonia plant is only operated on a seasonal basis (Spring and Fall). Full-time equivalent employee numbers were computed on that basis. At a maximum, the plant operates a total of three months (1/4 of the year). T
he FTEs for this company location is two (2).
THE WORST-CASE AND ALTERNATIVE RELEASE SCENARIO:
The worst-case scenario is the failure of the one (1) 30,000-gallon storage tank when filled to the greatest amount allowed (85% of capacity), resulting in the release of the total volume in a gaseous (hazardous ammonia vapor cloud) form. According to EPA's RMP*Comp Program (Version 1.06), the distance to the endpoint is 4.4 miles.
The alternative release scenario involves the transport delivery vehicle pulling away from the intake lines into the storage plant without disconnecting the transfer hoses. The resulting release, according to EPA's RMP*Comp Program has a distance to endpoint of 0.1 miles.
Since this facility is located in relatively close proximity to the Town of Cascade, provisions have been designed to notify all affected persons in Cascade, as well as the locale of Fillmore. An evacuation plan is in place.
