Central Montana Co-op Liquid Plant - Denton - Executive Summary |
|
The management and employees of Central Montana Co-op - Denton are committed to the prevention of any accidental releases of anhydrous ammonia. If an accidental release should occur, Central Montana Co-op is prepared to work with the local fire department, or other authorities, to mitigate any release and minimize the impact of the release to the people and the environment. The primary activity at Central Montana Co-op 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 fertilizer for crop production nutrients. The maximum quantity stored would be 140,200 pounds in our 30,000 gallon storage tank. The maximum quantity handled would be the unloading of a delivery truck holding 42,000 pounds. The worst-case release scenario would be the release of the total contents of our storage tank released as a gas over 10 minutes. The maximum quantity released would be 140,200 pounds, which represents the volume of the storage tank at 85 percent capacity as limited by the design standards. The distance to the endpoint is 1.63 miles. The alternative release scenario would be the failure of the loading hose which would release 11,908 pounds over two minutes. The distance to endpoint would be .6 miles. Central Montana Co-op has implemented the provisions of "Safety Requirements of 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 ( OSHA ), 29 CFR 1910.111, "Storage and handling of Anhydrous Ammonia". There have been no accidental releases of anhydrous ammonia 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 offsite deaths, injuries, evacuation, sheltering in place, property damage or environmental damage. Centr al Montana Co-op's emergency response program is provided to the state and county under the emergency planning and community right-to-know information as required under SARA Title III (EPCRA). Safety improvement is an on-going process at Central Montana Co-op. Periodic evaluations are performed to assess the maintenance of safe conditions. There are no additional specific anhydrous ammonia safety recommendations for implementation at this time. |
