Aredale Farm Center - Executive Summary |
|
Facility: AREDALE FARM CENTER; Aredale, IA Contact:Terry Fliehler Phone: 515-894-3435 1. Facility Policy. The owners, management and employees ofAredale Fram Center (the facility) 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 Aredale Fire Department, Butler County LEPC, 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 and for crop production nutrients. One (1) 30,000 gallon Anhydrous Ammonia storage tank is on site. The maximum quantity stored at 85% capacity would be 131,146 pounds. We have Safety and Emergency Action Plan in place. We provide our employees with appripriate training for handling Anydrous Ammonia and responding to accidental releases. We update our Programs periodically as needed. Maintenance is performed as needed and documented in our files. In order to evaluate potential accidental releases, we performed an off-site consequence analysis using guidance from the Fertilizer Institute. 3.Worst-Case Scenario and Alternate Release Scenario a: The worst-case scenario would be the release of the total contents of the storage tank released as gas over a period of 10 minutes. The maximum quantity released would be 131,146 pounds, which represents the volume of the largest storage tank at 85 percent capacity as limited by design standards. The distance to the end point (point of dispersion to 200 parts per million, or ppm) is 2.40 miles. b: The alternate release scenario, based on the five-year accident history (or the most likely potential incident), is a release from a break in a 3-inch transfer hose followed by release of ammonia for 2 minutes before an automatic excee flow valve or manual shut-off intervenes and stops the flow of ammonia. The maximum quantity released would be 11908 pounds. The distance to the endpoint (point of dispersion to 200 ppm) is .8 miles. 4.Accidental Release Prevention Program The facility has been reviewed for general compliance with the provisions of "Safety Requirements for the Storage and handling of Anhydrous Ammonia, K-61.1", published by The American National Standards Institute, Inc. (ANSI), and the standards of the U.S. Occupational Safety and Health Administration (OSHA), 29 CFR 1910.111, "Storage and handling of anhydrous ammonia". The ANSI Standard has been adopted by reference by Iowa Administrative Code Part 21-Chapter 43-Rule 43.6(200)-Standard for the storage and handling of anhydrous ammonia. The OSHA standard is referenced in the Registration Form Section 8.3.b. 5.Five-Year Accident History. There have been no accidental releases of anhydrous ammonia in the past five years that: have caus ed any deaths, injuries or significant property damage at the facility; nor to our knowledge, have resulted in off-site deaths, injuries, evacuations, sheltering in place, property damage, or environmental damage. 6.Emergency Response Program. The facility has: a. An written action plan, in accordance with OSHA standard 29 CFR 1910.38; b. Provided state and local authorities with the emergency planning and community right-to-know information as required under SARA Title III (EPCRA); c. This facility is included in the Butler County's Emergency Response Plan. 7.Planned Changes to Improve Safety. Safety improvement is an on-going process at the facility. Periodic evaluations are performed to assess the maintenance of safe conditions. There are no additional specific safety recommendations regarding storage or use of anhydrous ammonia for implementation at this time. |
