St. John Grange Supply-Diamond Spear - Executive Summary |
|
We are a fertilizer retail facility. The only material considered hazardous at this facility is anhydrous ammonia. The facility has one 12,000 gallon tank, equipment for receiving ammonia by truck, and equipment for transferring ammonia from storage to trucks for delivery to customers. It is our policy to meet, or exceed, all local, state, and national standards relating to handling ammonia. In the past five years, we have not had any accidents or releases with off-site consequences. Specific safety features that we employ to minimize the impact of an accidental release include: 1. Excess flow valves to prevent flow from the tank or trucks if any hose or line breaks. 2. Pressure relief valves on the storage tank to prevent overpressuring and rupture of the tank. To further ensure safe operation of the facility, our employees are trained in procedures for safe handling of hazardous materials, and in safe operating and maintenance procedures. We have also coordinated with the St John Volunteer Fire Department to respond in the unlikely event of an emergency. As required by the EPA, we have analyzed the worst-case release scenario defined by the EPA. This scenario involves a release of the entire contents of the storage tank. According to information supplied by the EPA the impact from this scenario would extend 4.2 miles from our facility, and would impact residences, but would not impact any schools, or commercial areas. It is extremely unlikely that an event such as EPAs worst-case release scenario will ever occur. A more probable, but still highly unlikely event, would be an event like a hose break during a truck pull away. According to information supplied by the EPA, the impact from such a release would only extend 2000 feet and would not impact any residences, schools, or commercial areas. Our registration information indicates no full-time employees at this site. This is because this facility is an unmanned facility, and employees are only at th e site for the brief time it takes to fill a truck. |
