Risk Management Plan - Executive Summary Facility: Clarinda Co-Op Co. Clarinda, IA Contact: Larry Winters Phone: 712-542-2146 1. Facility Policy. The owners, management and employees of Clarinda Co-Op Co. (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 3 storage tanks, for AA- one at 18,000 and 30,000 gallons; for propane- one at 25,000 gallons. The maximum quantity stored would be 204,000 pounds for AA, for propane, 78,600 pounds. 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 127500 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 for propane would be the release of the total contents of a storage tank. The maximum quantity released would be 78,600 pounds, which represents volume of the largest storage tank at 85 percent capacity. The distance to the end point ( 1.0 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 release from a break in a transfer hose. The distan ce to the endpoint (point of dispersion to 200 ppm) is 1.2 miles. The alternate release for propane is based on a hose rupture caused by a pull- away. The distance to the endpoint (1.0 psi overpressure) is 0.03 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 21Chapter 43Rule 43.6(200)-Standard for the storage and handling of anhydrous ammonia. The applicable standard for propane is NFPA-58. The OSHA standard is referenced in the Registration Form Section 8.3.b. 5. Five-Year Accident History. There have been no accident al 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, including 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 anhydr ous ammonia and propane for implementation at this time. |
