Chippewa Falls Anhydrous Ammonia Facility - Executive Summary
Risk Management Plan |
Clean Air Act Amendment, Section 112r
ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES
The owners, management and employees of the Cooperative are committed to the prevention of any accidental release of anhydrous ammonia. The Cooperative's policy is to adhere to all applicable Federal and State rules and regulation in order to:
1. Prevent unnecessary human exposure,
2. Reduce the threat to employees health, and
3. To reduce the threat to nearby members of the community.
Safety depends upon the manner in which an accidental release is handled, combined with the safety devices inherent in the design of the operation, the safe handling procedures used and the training of personnel.
This Cooperative complies with the provision of "Safety Requirements for 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 Heath Administ
ration (OSHA), 29 CFR 1910.111, "Storage and Handling of Anhydrous Ammonia". The Cooperative's emergency response plan includes procedures for notification of the local fire authority, the LEPC and any potentially affected neighbors.
STATIONARY SOURCES AND REGULATED SUBSTANCES
At this facility, anhydrous ammonia is stored and distributed for resale to farmers and other customers.
Anhydrous ammonia is received by truck, and stored in a 30,000 gallon tank. The anhydrous ammonia is distributed and used for direct application to customers fields for crop production nutrient.
The maximum amount of anhydrous ammonia that can be stored at this facility is 119,000 pounds (30,000 gallon tank times 4.67 pounds/gallon times 85%).
Worst case scenario - Failure of the 30,000 gallon tank when filled to 85% capacity would release 119,000 pounds. The anhydrous ammonia would be released as a gas over a 10 minute period (11,900 pounds per mi
nute). The distance to the endpoint under urban conditions using the degadis model (toxic endpoint is 200 ppm) is 1 miles.
Alternate Scenario - A hose breaks resulting in a release of 5% of the tank or 5950 pounds. The release is stopped through human intervention in 2 minutes (2975 lbs/min). The distance to the endpoint under urban conditions is 0.3 miles.
GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND THE SPECIFIC PREVENTION STEPS
This distribution facility complies with EPA's Accidental Release Rule and with all applicable state codes and regulations.
The anhydrous ammonia facility has implemented the provision of "Safety Requirements for Storage and Handling of Anhydrous Ammonia, K-61.1", published by The American National Standards Institute, Inc., and the standards of the U.S. Occupation Safety and Health Administration (OSHA), 29 CFR 1910.111, "Storage and Handling of Anhydrous Ammonia".
