Executive Summary

The Plaquemine Natural Gas Plant ("Plaquemine Plant" or "Facility") utilizes more than the threshold quantity of a "regulated flammable substance (10,000 pounds)" in the processing of natural gas, where inlet gas is treated by an amine unit to remove sulfur, is then further treated to remove natural gas liquids (NGL), which are further fractionated, and residue gas (methane) is returned to a transmission pipeline. Therefore, this Facility is subject to the Risk Management Plan (RMP) requirements codified in Title 40 of the Code of Federal Regulations Part 68 (40 CFR 68) administered by the U.S. Environmental Protection Agency (EPA).



No public receptors are located within the worst-case release scenario for the Facility. The Facility has not had an accidental release of a regulated substance which led to off-site death, injury, or response or restoration activities for an exposure of an environmental receptor, and the Facility coordinates emergency response procedures with the local fire department. Therefore, the Plaquemine Plant is subject to Program 1 requirements as stated in 40 CFR 68.10.



The Plaquemine Plant employs twenty-one (21) full-time employees on-site who will ensure the proper operation and maintenance of the Facility.



EnLink Midstream Operating, L.P. (EnLink) last submitted a RMP to the United States Environmental Protection Agency (USEPA) in January 2014. The current RMP includes administrative updates associated with the change from Crosstex Energy to EnLink.



ACCIDENTAL RELEASE PREVENTION AND RESPONSE POLICIES



The Plaquemine Plant maintains a policy of safe NGL extraction and separation operations, reducing to the greatest extent possible hazards associated with the extraction and separation processes, and reducing subsequent risk to the surrounding community, employees, and the environment.



The Plaquemine Plant has procedures in place, including both on-site activities and coordination with off-site responders that a
re to be followed in the event of an NGL, butane, isobutane, ethane, or propane release.



STATIONARY SOURCE AND REGULATED SUBSTANCES HANDLED



The Plaquemine Plant processes NGL in various aboveground vessels and associated piping and valves. NGL is a regulated flammable mixture that is an aliphatic and aromatic hydrocarbon mixture. After additional processing, the Facility also generates and stores for off-site transfer other products extracted from the NGL. Table 1-1 details the Facility inventory of RMP-regulated materials, as well as the largest vessel of each material.

EnLink has completed an assessment of materials stored at the Facility and determined that no RMP-regulated toxics are present above threshold quantities.



GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND CHEMICAL SPECIFIC PREVENTION STEPS



Because the Facility is regulated under RMP Program Level 1, it is not subject to the RMP Prevention Program required under 40 CFR 68. However, the Facility is subje
ct to the Occupational Safety and Health Administration's (OSHA) Process Safety Management (PSM) program. The Plaquemine Plant's PSM Plan is kept on-site as a separate document.



FIVE-YEAR ACCIDENT HISTORY



The Plaquemine Plant has not had an accidental release of NGL, butane, isobutane, ethane, or propane that resulted in deaths, injuries, or significant property damage on-site, or off-site deaths, injuries, evacuations, sheltering in place, property damage or any environmental impact for the life of the Facility.



EMERGENCY RESPONSE PROGRAM



Because the Plaquemine Plant is regulated under RMP Program Level 1, it is not subject to the RMP Emergency Response Program required under 40 CFR 68. However, the Facility does maintain a written Emergency Action Plan (EAP) that provides guidance for emergencies expected at the Facility. In addition, operating procedures and equipment design codes and standards associated with the operations at the Facility are maintained. Furthermore, the Facility has coordinated emergency response with the Iberville Parish Office of Emergency Preparedness (OEP) and the Plaquemine Fire Department, which is also designated as the first responder in the event of flammable material release.



A site map, MSDSs, and a list of chemicals kept on-site are maintained at the Facility, along with their PSM Plan, which is kept on-site as a separate document.



PLANNED SAFETY IMPROVEMENTS



The Plaquemine Plant has a continued commitment to update equipment and improve safety pertaining to the covered process when necessary. The Facility completes maintenance checks, compliance audits, management of change procedures, and incident investigations to identify changes to improve safety.
