Accidental Release Prevention and Response



At Enterprise, we are committed to operating and maintaining all of our processes (especially those using hazardous substances) in a safe and responsible manner. We use a combination of accidental release prevention programs and emergency response planning programs to help ensure the safety of our employees and the public as well as protection of the environment. This document provides a brief overview of the comprehensive risk management activities that we have designed and implemented, including:



* A description of our facility and use of substances regulated by EPA's RMP regulation

* A summary of results from our assessment of the potential off site consequences from accidental chemical releases

* An overview of our accidental release prevention programs

* A five-year accident history for accidental releases of chemicals regulated by EPA's RMP rule

* An overview of our emergency response program

* An overview of planned improvements at the facility to help prevent accidental chemical releases from occurring and adversely affecting our employees, the public, and the environment



Description of the Stationary Source and Regulated Substances



The Burns Point Gas Plant is located in St. Mary parish, Louisiana. The plant is owned by Enterprise Gas Processing LLC and Marathon Oil Company and operated by Enterprise Products Operating LLC



The Gas Plant is a cryogenic expander plant that extracts natural gas liquids from an inlet stream of production natural gas. The Burns Point Gas Plant has regulated flammable mixtures in gas and pressurized liquid form, but it has no regulated toxic substances. The recovered mixed hydrocarbon Y-Grade product is transported from the facility via pipeline. The Plant is subject to the Occ
upational Safety and Health Administration (OSHA) Process Safety Management (PSM) Standard and is classified as a Program Level 3 site under the EPA Risk Management Program rule.



Toxics



No toxic materials to report.



Flammables



Listed flammable substances that are present above the threshold quantities at the Burns Point Gas Plant are natural gas liquids and inlet natural gas.



Offsite Consequence Analysis Results



The offsite consequence analysis will not be reflected in the executive summary but rather is reflected in the data components. There are flammable substances on site and no toxic substances above the threshold quantity.



General Accident Release Prevention Program



The following is a summary of the accident prevention program in place at the Burns Point Gas Plant. The processes at the plant are regulated by the Environmental Protection Agency (EPA) Risk Management Program (RMP) regulation (Program 3), and are also subject to the OSHA's PSM Standard. This summary addresses each of the PSM program elements and describes the management system in place to implement the accident prevention program which is required only by the facility OSHA PSM regulation coverage.



Employee Participation



Enterprise strongly promotes employee involvement in safety issues through existing programs. These programs include regularly scheduled safety meeting, tail-gate safety meetings, hazard communications, a "near-miss" reporting system and special training programs such as emergency response training, first aid training, etc.



Enterprise actively seeks employee involvement in the development and conduct of all accident prevention activities through the appropriate existing safety programs. Employees are encouraged to discuss accident prevention with their supervisors and to bring any questions, comments or suggestions forward for open discussion.



Process Safety Information



Enterprise keeps a variety of technical documents that are used
to help maintain a safe operating process. These documents address chemical properties and associated hazards, limits for key process parameters, specific chemicals inventories and equipment design basis/configuration information. Chemical specific information, including exposure hazards and emergency response/ exposure treatment considerations is provided in material safety data sheets (SDS).



Enterprise also maintains numerous technical documents that provide information about the design and construction of process equipment. This information includes materials of construction, design pressure ratings, temperature ratings and electrical rating of equipment.



Process Hazard Analysis (PHA)



Enterprise primarily uses the hazard and operability (HAZOP) and Checklist method analysis technique to perform these evaluations. The analyses are conducted using a team of Enterprise staff which has operating and maintenance experience as well as engineering expertise. This team identifies and evaluates hazards of the process as well as accident prevention and mitigation measures, and the team makes recommendations for additional prevention and/or mitigation measures when the team believes such measures are necessary.



The PHA team findings are forwarded to local and corporate management for resolution. Implementation of mitigation options in response to PHA findings is based on a relative risk ranking assigned by the PHA team. This ranking helps ensure that potential accident scenarios assigned the highest risk receive immediate attention. All approved mitigation options in response to PHA team findings are tracked until they are completed. The final resolution of each finding is documented and retained.



As part of Enterprise Process Hazard Analysis program, the facility will periodically update and revalidate the hazard analysis results.



Operating Procedures



The Burns Point Gas Plant maintains written procedures that address various modes of p
rocess operations such as; (1) start-up, (2) normal operations, (3) temporary operations, (4) emergency shutdown, (5) normal shutdown and (6) initial startup of a new process. These procedures provide guidance for experienced operators and also provide the basis for training new operators. Operating procedures include applicable safety precautions that must be taken in the operation of the facility. The procedures are periodically reviewed and annually certified as current and accurate. The review and certification process involves both operators and technical staff.



Training



In addition to training on operating procedures, the Burns Point Gas Planthas a comprehensive training program for all employees involved in operating the process. New employees receive basic training in gas plant operations and safe work practices. All operators receive refresher training on the operating procedures at least every three years to ensure that their skills and knowledge are maintained at an acceptable level.



Contractors



The Burns Point Gas Plant uses contractors during periods of increased maintenance or construction activities. Because some contractors work on or near process equipment, the plant has procedures in place to ensure that contractors (1) perform their work in a safe manner, (2) have appropriate knowledge and skills, (3) are aware of the hazards of their workplace, (4) understand what they should do in the event of an emergency, (5) understand and follow site specific safety rules and (6) inform plant personnel of any hazards that they find while performing their work. This is accomplished by providing contractors with an orientation session that covers (1) a process overview, (2) information about the safety and health hazards, (3) emergency response plan requirements and (4) safe work practices prior to beginning their work. In addition, Enterprise evaluates contractor safety programs and performance during the contractor selection process.
Enterprise personnel periodically monitor contractor performance to ensure that contractors are fulfilling their safety obligations.



Pre-Startup Safety Review (PSSR)



The Burns Point Gas Plant conducts a PSSR prior to the startup of all new facilities or any modification that requires a change in process safety information. The purpose of the PSSR is to ensure that safety features, procedures, personnel and equipment are appropriately prepared for startup prior to placing the equipment into service.



Mechanical Integrity



The Burns Point Gas Plant has well established practices and procedures for maintaining process equipment. The basic aspects of this program include (1) training, (2) developing written procedures, (3) performing inspections and tests, (4) correcting equipment deficiencies, when identified and (5) applying quality assurance measures. In combination, these activities form a system that maintains the mechanical integrity of the process.



Safe Work Practices



The Burns Point Gas Plant has safe work practices in place to help ensure worker and process safety. Examples of these include: (1) control of the entry/presence/exit of support personnel, (2) a lockout/tagout procedure to ensure isolation of energy sources for equipment undergoing maintenance, (3) a procedure for safe removal of hazardous substances before process piping and equipment is opened, (4) a permit and procedure to control spark-producing activities (i.e. hot work) and (5) a permit and procedure to ensure that adequate precautions are in place before entry into a confined space. These procedures, along with training of affected personnel, form a system to help ensure that operations and maintenance activities are performed safely



Management of Change



The Burns Point Gas Plant uses Enterprise software-based change approval system to manage change to all covered processes. This system requires that changes to items such as process equipment, technology, procedu
res and other facility changes be properly reviewed and authorized before being implemented to ensure that the safety of the facility is not compromised by the change. Operating and maintenance personnel are provided any necessary training on any changes as part of the change management process.



Incident Investigation



The Burns Point Gas Plant promptly investigates all incidents that resulted in or reasonably could have resulted in, a fire/explosion, major property damage, environmental loss, or personal injury. The investigation team documents its findings, develops recommendation(s) to prevent a reoccurrence and forwards these results to the business management team for resolution.



Compliance Audits



To help ensure that the accident prevention program is functioning properly, Enterprise periodically conducts an audit of the program to determine whether the procedures and practices required by the accident prevention program are being implemented. Compliance audits are conducted at least every three years. Both hourly and staff personnel participate as audit team members. The audit team develops findings that are forwarded to operations or facility management for resolution. The final resolution of each finding is documented, and the two most recent audit reports are retained.



Chemical Specific Prevention Steps



The processes at the Burns Point Gas Plant have hazards that must be managed to ensure continued safe operation. The following is a description of existing safety features applicable to prevention of accidental releases of regulated substances in the facility.



Universal Prevention Activities



The accident prevention program summarized previously is applied to all RMP covered processes at the Burns Point Gas Plant. Collectively, these prevention program activities help prevent potential accident scenarios that could be caused by equipment failures and human errors.



Specialized Safety Features



The Burns Point Gas Plant has s
afety features on many units to help contain/control a release, to quickly detect a release and reduce the consequence of a release. The following types of safety features are used in the covered processes:





Release Detection



* Hydrocarbon (hazardous gas) detectors and alarms

* Fire detectors on gas compression equipment

* Plant video surveillance system



Release Containment and Control



* Process relief valves that discharge to a remote vent away from the process area.

* Valves to permit isolation of the process (manual or automated).

* Automatic shutdown systems for specific process parameters (e.g., high pressure).

* Secondary containment (curbs and dikes) to contain any release of liquid chemicals

* Redundant equipment and instrumentation where advisable

* Dual mechanical seals with seal failure alarms installed on hydrocarbon liquid pumps.

* Atmospheric relief devices





Release Mitigation



* Hand-held and wheeled cart fire extinguishers

* Personnel trained in emergency response and procedures.

* Personnel protective equipment (e.g., chemical protective clothing, hard hats, safety glasses, etc.)



Five Year Accident History



There was a small incident involving a release of compressor fuel gas in February of 2012. The release did not involve any offsite injuries or deaths, and did not require any response to environmental receptors. Additional details on the incident are given in the registration 5-year Accident History section.



Emergency Procedures Information



The Burns Point Gas Plant maintains a written emergency procedure, which is in place to protect worker and public safety as well as the environment. The procedures are for the possibility of a fire or explosion if a flammable substance is accidentally released. The procedures address notification of local emergency response agencies if a release occurs. Employees receive training in emergency procedures. The emergency procedure is updated when necessary based
on modifications made to the plant facilities.



The overall emergency procedure program for the Burns Point Gas Plant is coordinated with the St. Mary Parish Emergency Management organization (LEPC). This coordination includes periodic meetings of the committee, which includes local emergency response officials, local government officials and industry representatives. The Burns Point Gas Plant has around-the-clock communications capability with appropriate LEPC officials and emergency response organizations (e.g., fire department). This provides a means of notifying the public of an incident, if necessary, as well as facilitating quick response to an incident.



Planned Changes to Improve Safety



The Burns Point Gas Plant resolves all findings from PHAs, some of which result in modifications to the process. Other recommendations for possible changes to improve safety come from periodic accident prevention program audits, incident investigations, or employee suggestions and recommendations. The following changes are planned for implementation at the Burns Point Gas Plant.



* Burns Point Plant has recently installed a facility video surveillance systemfor improved operations monitoring and security surveillance.

* The plant has recently installed additional ultraviolet/infrared flame detectors in the gas compressor building for improved detection of incipient fires.

* Enterprise is currently in the process of reviewing and revising the entire safety management / accident prevention program to ensure that the program can be fully administered across the diverse nature of the facilities owned or operated by the company.
