Risk Management Plan - Executive Summary Facility: Farmers Elevator and Exchange of Wapello, Iowa Contact: Raymond Fisher Phone: 319-523-5351 1. Facility Policy. The owners, management and employees of Farmers Elevator and Exchange of Wapello, Iowa (the facility) are committed to the prevention of any accidental releases of anhydrous ammonia and propane. If an accidental release should occur, the facility is prepared to work with the local fire department, 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 and blending of fertilizers for sale to farmers. Anhydrous ammonia is received, stored and distributed for both direct application and for blending into mixed-grade fertilizers for crop production nutrients. Anhydrous ammonia and propane are stored at the facility in 5 storage tanks the ammonia is stored 30,000 gallons, 18 000 gallons and 2 at 12,000 gallons. The propane is stored in two tanks one at 18,000 gallons and the other at 30,000. The maximum quantity stored for anhydrous ammonia is 258,000 pounds. For the propane the maximum is 177,000 pounds stored. 3. Worst-Case Scenario and Alternate Release Scenario a. The worst-case scenario would be the release of the total contents of a storage tank released as gas over a period of 10 minutes. The maximum quantity released would be 130,000 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 2.4 miles. The worst-case scenario for propane is the maximum quantity released would be 110,000 pounds. The distance to the end point (point of 1 psi overpressure) is 0.4 miles. b. The alternate release scenario, based on the five-year accident history (or the most likely potential incident), is a relea se from a break in a transfer hose. The distance to the endpoint (point of dispersion to 200 ppm) is 1.2 miles. The alternate release scenario for propane is a release from a hose rupture caused by a pull-away and assumes a 25-foot length of a 4-inch transfer hose. The active mitigation devices are assumes to function as designed, limiting the release to the contents of the hose. The maximum quantity released would be 69 pounds. The distance to the end point (point of 1 psi overpressure) is 0.03 miles, or 175 feet. 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 ref erence by Iowa Administrative Code Part 21-Chapter 43-Rule 43.6(200)-Standard for the storage and handling of anhydrous ammonia. The applicable standard for propane is NFPA-58. The standards listed above are referenced in the Registration Form Section 8.3.b. 5. Five-Year Accident History. There have been no accidental releases of anhydrous ammonia or propane in the past five years that: have caused 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. a 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. a written emergency response program, in accordance with OSHA standard 29 CFR 1910.120, inclu ding pre-emergency planning and employee training. 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 and propane for implementation at this time. |
