NORTH SLIGO REFRIGERATION FACILITY RISK MANAGEMENT PLAN: EXECUTIVE SUMMARY
ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES
Chesapeake Energy Marketing, Inc. (Chesapeake) has a long-standing commitment to workers and public safety. This commitment is demonstrated by the resources invested in accident prevention such as training personnel and considering safety in the design, installation, operation, and maintenance of the facility's processes. The Chesapeake policy is to implement reasonable controls to prevent foreseeable releases of substances.
DESCRIPTION OF THE STATIONARY SOURCE AND REGULATED SUBSTANCES
Chesapeake operates North Sligo Refrigeration Facility (North Sligo) in Bossier Parish, Louisiana. This facility is a natural gas processing plant which removes liquids from a gas stream. Glycol dehydration is used to remove water from the stream. Mixed liquids removed from the gas stream by Refrigeration Unit and are stored in a pressurized bullet tank prior to being shipped off site in tanker trucks. As evidenced in the ensuing text and based on criteria outlined in the Accidental Release Prevention (ARP) Program, North Sligo is a Program 1 process.
North Sligo was evaluated to determine if any regulated flammable or toxic substances were present in the process and if they exceeded threshold quantity. All equipment and vessels are considered to be connected and/or co-located; consequently, for the purposes of the ARP Program, all equipment and vessels are part of a single process. The identification of even a single vessel exceeding threshold quantity of a regulated flammable or toxic substance would subject a process to threshold determination for offsite consequence analysis.
Chesapeake identified one flammable liquid mixture and zero regulated toxic substances. The identification of this exceedance indicates that North Sligo is a covered process with a regulated substance subject to offisite consequence analysis.
North Sligo has not had any accidental releases that meet the criteria for an accidental release as discussed in 40 CFR 68.42.
LOCAL EMERGENCY RESPONSE COORDINATION
Since the facility is unmanned, Chesapeake will not implement a site-specific emergency response plan. Emergency response activities are coordinated with Bossier Parish LEPC as required in 40 CFR 68.12(b)(3).
