Executive Summary

PetroLogistics Lake Charles Depropanizer Plant, located in Sulphur, Louisiana, has a standing commitment to worker and public safety. This commitment is demonstrated by the resources invested in accident prevention, training of highly qualified personnel, and considering safety in the design, installation, operation and maintenance of our processes. Our policy is to implement reasonable controls to prevent chemical releases. However, if a release does occur, our trained personnel will respond to control, contain, and mitigate the release.

PetroLogistics Lake Charles Depropanizer Plant uses a mixed hydrocarbon gas feed to produce several regulated flammables such as propane, butane and ethane. Chemicals maintained on site at the plant, listed on the EPA's list of flammable chemicals, and are above EPA's threshold quantity are butane, isobutane and propane. Other regulated chemicals used in our process, which are stored below the threshold quantity, may be present but not subject to RMP.

Process Safety Information

The Lake Charles Depropanizer Plant maintains a variety of technical documents that are used to help maintain safe operation of the processes. These documents address chemical properties and associated hazards, limits for key process parameters, specific chemical inventories, and equipment design basis/configuration information. Specific departments within the chemical complex are assigned responsibility for maintaining up-to-date process safety information. Employees are provided training on how to locate the information from various computer terminals located throughout the chemical complex.

Chemical specific information, including exposure hazards and emergency response/exposure considerations, is provided in material safety data sheets (MSDS). This information is supplemented by documents that address known corrosion concerns and known hazards associated within inadvertent mixing of specific chemicals. For the different process are
as, the chemical complex has documented safety related limits for specific process parameters (e.g. temperature, pressure, composition, etc.). The chemical complex insures that the processes are maintained within the limits using process controls, monitoring instruments, protective instrument systems, and highly trained personnel.

The Lake Charles Depropanizer Plant also maintains a database, this accessible by both the employees and contractor supervision, which provides information about the design pressure and temperature ratings, electrical classification, etc. This information in combination with written procedures and trained personnel provides a basis for establishing inspection and maintenance activities as well as for evaluating proposed process and facility changes to ensure that safety features in the process are not compromised.

Process Hazard Analysis

The Lake Charles Depropanizer Plant has a comprehensive program to help ensure the hazards associated with the various processes are identified and controlled. Within this program, each process is systemically examined to identify hazards and ensure that adequate controls are in place to manage these hazards.

The Lake Charles Depropanizer Plant primarily used the What-if/Checklist method for future Process Hazard Analysis. The analysis is conducted using a team of people who have operating and maintenance experience as well as engineering expertise. The team identifies and evaluates hazards of the process as well as accident prevention and mitigation measures, and makes suggestions for additional prevention and/or mitigation measures when the team believes such measures are necessary.

The PHA team findings are made available to people associated with the process for comments and forwarded to local and corporate management for resolution. Implementation of mitigation options in response to PHA findings is based on a relative ranking assigned by the PHA team. This ranking helps ensure
that potential accident scenarios assigned the highest rank receive immediate attention. All approved mitigation options being implemented in response to PHA findings are tracked until they are complete. The final resolution of each finding is documented and retained.

Operating Procedures

Operators, supervisors, and plant engineers work together to develop and maintain operating procedures. These procedures define how tasks related to process operations and safely performed. At the Lake Charles Depropanizer Plant, operating procedures are used to train employees and serve as reference guides for appropriate actions to take during both normal operations and process upsets. Operating procedures include:

- Steps for safely conducting activities

- Applicable process safety information, such as safe operating limits,

- Safety and health considerations, such as chemical hazards, personnel protective equipment required and steps to take if exposed to a particular chemical.

Plant personnel develop and maintain operating procedures that cover all phases of operations, including initial startup, normal operation, normal shutdown, emergency shutdown, startup following a turnaround or emergency shutdown, and temporary operations.


The Lake Charles Depropanizer Plant trains its workers to safely and effectively perform their assigned tasks. The training program includes both initial and refresher training.

All new employees assigned as operators receive comprehensive training before being assigned to a specific operating area. This training includes training on specific types of equipment, such as pumps and compressors, general overview of the process, properties and hazard substances in the process, and detailed review of complex procedures, such as, safe work practices and of emergency response. Oral review and written tests are used to verify that employees understand the training material before a new employee can report to a process u
nit. Once a new employee reports to a particular process area, he receives detailed training with respect to process specific procedures and for specific tasks; he is allowed to begin work in a specific operating area.

Annual refresher training covers a general overview of the process, the properties and hazards of the substances in the process and, a review of the process operating procedures and safe work practices. Oral review and written tests are used to verify that employees understand the training before an employee can resume work in the process. The operators have been consulted in safety meetings and through questionnaires regarding effectiveness and frequency of training. Recommendations are reviewed and changes to the training program are implemented as appropriate.

Management of Change

The Management of Change program for the Lake Charles Depropanizer Plant evaluates and approves all proposed changes to chemicals, equipment, and procedures for covered processes to help ensure that a change does not negatively affect safe operations. Process changes that are determined to be a replacement in kind (e.g. replacing a valve with an identical valve) are allowed without completing a full management of change program. All other changes must be confirmed through a full management of change program to help ensure process safety information and procedures are updated, and affected employees are notified of the change.

Pre-Startup Safety Review (PSSR)

The Lake Charles Depropanizer Plant conducts a safety review of a new or modified process before the process is placed in service. The purpose of the PSSR is to ensure the safety features, procedures, personnel and equipment are appropriately prepared for startup prior to placing the equipment in service. The review provides one additional check to make sure construction of new processes and significant modifications to existing processes are, in accordance with the design specifications and
that all supporting systems are operationally ready. The PSSR review team uses checklists to verify all aspects of readiness. A PSSR involves field verification of the construction and serves a quality assurance function by requiring verification that accident prevention program requirements are properly implemented.

Mechanical Integrity

The Lake Charles Depropanizer Plant has well established practices and procedures to maintain pressure vessels, piping systems, relief and vent systems, controls, emergency shutdown systems, and rotating equipment (pumps and compressors) in a safe operating condition. The basic aspects of this program include (1) conducting training, (2) develop written procedures, (3) perform inspections and tests, (4) correcting identified deficiencies and, (5) applying quality assurance measures. In combination, these activities form a system that maintains the mechanical integrity of the process.

Maintenance personnel receive training on (1) an overview of the process, (2) safety and health hazards, (3) applicable maintenance procedures, (4) emergency response plans, and (5) applicable safe work practices. Written procedures help ensure that work is performed in consistent manner and provides basis for training. Inspections and tests are performed to help ensure that equipment is within acceptable limits (e.g. adequate wall thickness for pressure vessels). If a deficiency is identified, the equipment will be repaired in a timely manner. All outstanding deficiencies are tracked until such time a final solution has been implemented and documented.

Another integral part of the mechanical integrity program is quality assurance. The Lake Charles Depropanizer Plant incorporates quality assurance into equipment purchase and repairs. This helps ensure that new equipment is suitable for intended use and that proper materials and spare parts are used when repairs are made.

Safe Work Practices

The Lake Charles Depropanizer Pla
nt has a safe work program in place to ensure worker safety. Examples of the program include (1) control of the entry/presence/exit of support personnel, (2) lockout/tagout procedures to ensure isolation of energy sources for equipment undergoing maintenance, (3) procedures for safe removal of hazardous materials before process piping or equipment is opened, (4) a permit and procedures to conduct spark producing activities (i.e. hot work), and (5) a permit and procedures 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.

Incident Investigation

The Lake Charles Depropanizer Plant investigates all incidents that could reasonably have resulted in a serious injury to personnel, the public, or the environment so similar incidents can be prevented. Employees at the plant are trained to identify and report any incident requiring investigation. The investigation is initiated within hours of the incident. Depending on the incident, an investigation team may be formed. Results of the investigation are documented and appropriate changes are made.

Employee Participation

The Lake Charles Depropanizer Plant maintains a written employee participation program to help ensure that safety and environmental concerns of the plant workers are addressed. The plant encourages active participation of personnel in safety, health, and environmental activities at the plant. Employees are consulted and/or informed about all aspects of the RMP prevention program including PHA's (Process Hazard Analysis) and operating procedures.

Compliance Audits

The Lake Charles Depropanizer Plant audits the covered processes to be certain that the prevention program is effectively addressing safety, health, and environmental issues. The complex assembles an audit team that includes personnel
knowledgeable in the processes. This team evaluates whether the prevention program satisfies the requirements of the RMP rule and whether the prevention program is sufficient to ensure safe operation of the complex. The results of the audit are documented, recommendations are resolved, and appropriate enhancements made to the operations of the plant.


The Lake Charles Depropanizer Plant has established a program to help ensure that contractor activities are performed in a safe manner. This program reviews the safety record of the contractors to ensure the plant only hires contractors who can safely perform the desired task. The complex communicates to the contractor supervisor the hazards of the process on which they and their employees will work, the plant's safe work practices, and the plant's emergency response procedures. The plant requires that the contractor supervisors train each of their employees on hazards and procedures specific to the complex site.
