The condensors are located on the roof above the mechanical room which house the compressors, pumps, and receiver. OCA guidance was used as the basis for these scenarios. Results for the worst case scenario of an ammonia release indicates that 9900 lbs. of ammonia would be released in a 10 minute duration at a rate of 545 lbs./ minute. This would be released inside the building with opening to the outside atmosphere. The estimated distance to the toxic endpoint is 0.4 miles with a wind speed of 3.4 miles
