1. Facility Policy.
The owners, management and employees of P & W AG, LLC. are committed to the prevention of any accidental releases of anhydrous ammonia. If an accidental release should occur, the facility is prepared to work with the local fire department, Washington County LEPC, and/or other authorities, to mitigate and minimize the impacts of the release to the people and the environment.
2. Facility Information.
The primary activity at the facility is the storage of fertilizers for sale to farmers. Anhydrous ammonia is received, stored and distributed for direct application as a nutrient for crop production. The maximum quantity stored would be 470,000 pounds in a storage tank and nurse tanks.
3. Worst-Case Scenario and Alternate Release Scenario
a. The worst-case scenario would be the rel
ease of the total contents of a storage tank released as gas over a period of 10 minutes. The maximum quantity released would be 78,000 pounds, which represents the volume of the largest storage tank at 85 percent capacity as limited by design standards and administrative controls. The distance to the end point (point of dispersion to 200 parts per million, or ppm) is 3.30 miles.
b. The alternate release scenario: a 3-inch transfer hose is used as an alternate scenario followed by release of ammonia for 2 minutes before an automatic excess flow shut-down valve/valves intervenes or remote manual shut-off is closed and stops the flow of ammonia. The maximum quantity released would be 28,000 pounds. The distance to the endpoint (point of dispersion to 200 ppm) is .59 mile ( The most likely potential incident, would be a release from a break in a 1-inch transfer hose release scenario followed by release of ammonia for 2 minutes before an automatic excess flow shut-
down valve/valves intervenes or remote manual shut-off is closed and stops the flow of ammonia. The maximum quantity released would be 2,901 pounds. The distance to the endpoint (point of dispersion to 200 ppm) is .22 miles).
