Western Iowa Co-Op - Executive Summary
Risk Management Plan for Western Iowa Coop |
P.O. Box 106, Hornick, Iowa 51026
For Locations at:
Blencoe, Correctionville, Hornick, Moville, Pierson, Sloan, Washta
1. Facility Policy
The owners, management and employees of Western Iowa Coop are committed to the prevention of any accidental releases of anhydrous ammonia or propane. If an accidental release should occur, the facility is prepared to work with the local fire department, or other authorities to mitigate any release and minimize the impact of the release to people and the environment.
2. Facility Information
The primary activity at our anhydrous ammonia facilities is the storage and blending of fertilizers for sale to farmers. The primary activity of our propane facilities is the storage and resale of propane to our member patrons.
Anhydrous ammonia is received, stored and distributed for both direct application and for blending into mixed grade fertilizers for crop production nutrients. Propane is st
ored and delivered to member patrons for use in heating and grain drying.
The maximum quantity of anhydrous ammonia stored (85% of capacity) varies by location:
Tank Size (gallons) Pounds
Blencoe, IA 30,000 131,325
Correctionville, IA 25,000 109,438
Hornick, IA 11,000 48,152
Total 34,000 148,834
Pierson, IA 12,000 52,350
Total 42,000 183,675
Sloan 25,000 109,438
Washta 18,000 78,795
Nurse tanks 24 112,506
The maximum quantity of propane stored (85% of capacity) varies by location:
Tank Size (gallons) Pounds
Blencoe, IA 28,000 99,996
Correctionville, IA 26,000 92,820
Hornick, IA 18,000 64,260
Pierson, IA 18,000 64,260
Total 36,000 128,520
Washta 12,000 42,840
Moville 18,000 64,260
3. The Worst Case Re
lease Scenario and the Alternative Release Scenario.
a. The worst case release scenario for anhydrous ammonia would be the release of the total contents of a storage tank released as a gas over 10 minutes. The maximum quantity release would be 78,795 pounds, which represents the volume of the storage tank(s) at 85 percent capacity as limited by design standards. The distance to the endpoint (point of 200 PPM) is 1.9 miles at the location with the largest storage.
The worst case release scenario for propane would be the release of the total contents of a storage tank released as a gas. The maximum quantity release would be 42,840 pounds, which represents the volume of the storage tank(s) at 85 percent capacity as limited by design standards. The distance to the endpoint (point of 1-psi overpressure) is a maximum of .4 miles at the location with the largest storage.
b. The alternative release scenario based on the five-year history (or the most likely potential incident) is a
release from a break in a transfer hose. The distance to the endpoint for anhydrous ammonia (point of dispersion to 200 ppm) is .83 miles.
The alternative release scenario based on the five-year history (or the most likely potential incident) is a release from a break in a transfer hose. The distance to the endpoint for propane (point of dispersion to 1 psi) is .3 miles.
4. Accidental Release Prevention Program.
Western Iowa Coop has implemented the provisions of "Safety Requirements for the Storage and Handling of Anhydrous Ammonia, K-61.1", published by the American National Standards Institute Inc., and the standards of the U.S. Occupational Safety and Health Administration (OAHA), 29 CFR 1910.111, " Storage and Handling of Anhydrous
Ammonia". In addition, we comply with all applicable federal (EPA), state and local requirements.
Western Iowa Coop has implemented the provisions of "LP-Gas Safety Handbook", part of NFPA-58, 1998 Edition, as well as applicable portions o
f the National Propane Gas Association (NPGA) Certified Training Program and safety bulletins, and the EPA's accident prevention policies. In addition, we comply with all applicable, state and local requirements.
5. The Five Year Accident History
Western Iowa Coop has had one accidental release of anhydrous ammonia in the past five years.
- 12-24-98: 118,450 pounds were released; the town of Blencoe was evacuated. This incident occurred when a railroad car derailed, hitting the anhydrous ammonia tank, shearing off the piping, including the excess flow valve. No deaths, injuries, environmental damage or property damage occurred, except to our storage tank and the railroad car.
Western Iowa Coop has had no accidental releases of propane in the last five years that: have caused any deaths, injuries, or significant property damage; not to our knowledge have resulted in offsite deaths, injuries, evacuations, sheltering place, property damage or environmental damage.
6. The Emerge
ncy Response Program.
Western Iowa Coop has:
a. a written emergency action plan, in accordance with OSHA Standard 29 CFR 1910.38;
b. provided state and local authorities the emergency planning and Community Right to Know information as required under SARA Title II (EPCRA).
c. A written emergency response program in accordance with OSHA standard, 29 CR 12910.120, including pre-emergency planning and employee training.
7. Planned Changes to Improve Safety
Safety improvement is an on-going process at Western Iowa Coop. Periodic evaluations are performed to assess the maintenance of safe conditions. There are no additional new specific anhydrous ammonia or propane recommendations for implementation at this time.
