Wayne Refrigeration Plant complies with OSHA PSM's prevention program. Furthermore, it is the policy of Cabot Oil & Gas Corporation to adhere to all applicable federal, state, and local laws. If an emergency were to occur, it is our policy to contact the Wayne Volunteer Fire Department and request that they respond to the emergency.
Description of Facility and Regulated Substances Handled
This facility condenses heavy hydrocarbons from a gas stream using a propane refrigeration cycle. These liquid hydrocarbons are stored in a 30,000 gallon tank before being hauled away periodically. The regulated substances in the facility include methane, ethane, propane, isobutane, butane, isopentane, and pentane.
Worst-Case and Alternative Release Scenarios
Our worst-case scenario is the failure of the 30,000 gallon storage tank when filled to the greatest amount allowed (88%), resulting in a vapor cloud explosion. The res
ulting distance to the endpoint extends offsite, and public receptors are within the distance to the endpoint.
Our alternative release scenario is a hose rupture as a result of a truck pull-away, leading to a 10-minute release and explosion. A pull-away can occur if the driver fails to remove the hoses between the storage tank and the transfer vehicle before moving the vehicle. The resulting distance to the endpoint extends offsite, and public receptors are within the distance to the endpoint.
General Accidental Release Prevention and Chemical-Specific Prevention Steps
This facility complies with OSHA's process safety management rule and all applicable state and local codes and regulations.
