Trident Seafoods Corporation Anacortes Plant - Executive Summary |
|
This Washington processing facility uses anhydrous ammonia as a refrigerant above the threshold quantity of 10,000 pounds to freeze and store seafood products. The quantity of ammonia used at the facility requires an OSHA Process Safety Management Program and an EPA Level 3 Risk Management Program to assure the health and safety of on-site employees, off-site public and environmental receptors. The facility's refrigeration system uses standard materials, components, and industry guidelines which provide overlapping layers of refrigeration system protection through automatic and manual reduction and mitigation of operating deviations. System changes have been changes in kind and have not required Management of Change or Startup Review. No on-site or off-site ammonia related incident resulted in an injury, death, property or environmental damage during the five year accident history period prepared for the Risk Management Plan. A ten minute unmitigated worst case release of 10,000 p ounds of ammonia and a ten minute unmitigated alternative release of 780 pounds of ammonia were scenarios selected from EPA models and data to illustrate ammonia plume dispersion. EPA Risk Management requirements will be integrated into the existing LEPC emergency response plan. |
