It is mandatory to observe safety precautions in handling ammonia to prevent unnecessary human exposure, to reduce the threat to personal health as well as co-workers, and to reduce the threat to nearby members of the community. It is Rio Bravo's policy to adhere to all applicable Federal and state rules and regulations. Safety depends upon the manner in which ammonia is handled. It is also dependent upon the safety devices inherent in the design of this facility combined with the safe handling procedures that are used and the training of our personnel.

The worst-case release scenario and the alternative release scenario, including administrative controls and mitigation measures to limit the distances for each reported scenario. ' Worst-Case Scenario (Amonnia). Failure of large storage tank when filled to the greatest amount customarily experienced would release 52,734 pounds of ammonia. (National Board (or ASTM) regulations limit the maximum filling capacity of this tank to 85 percent). It is assumed that the entire contents are released as vapor. The distance to the endpoint for the worst-case scenario is 4.0 miles. This distance extends beyond the facility boundary and encompasses some residences. ' Alternative Scenario (Ammonia): A truck backs into the tank a nd leaves a 1/4 inch diameter hole in the tank. One half of the contents of the tank are released over a one hour period. The distance to the endpoint for the alternative scenario is 0.2 miles. This distance extends beyond the facility boundary and encompasses an adjacent public road. 4.
