Lake Charles Refinery Risk Management Plan Executive Summary AIRI Lake Charles Refinery has a long-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 hydrocarbon releases. However, if a release does occur, our trained personnel will respond to control, contain, and mitigate the release. AIRI is committed to voluntary initiative for safe management of chemicals. AIRI follows an internal code of Management Practice, which is integral to the implementation of the AIRI Environmental and Health and Safety policies. The Community Awareness Code of Management Practice and AIRIs Community Awareness and Emergency Response policies are design ed to assist emergency preparedness and to faster community right to know. The AIRI Lake Charles Refinery, located in Calcasieu Parish, Louisiana, uses crude oil and certain additives as the primary raw materials to produce naphtha, kerosene, diesel fuel and asphalts. The refinery uses or produces several regulated flammables such as propane, butane, methane. There are no chemicals listed in the EPAs list of toxic chemicals which are maintained on site. The WCS (worse case scenario) associated with the release of a flammable substance involves the release of largest inventory, in a single vessel, of mixed propane and butane. Such a release would require a catasatrophic failure of a pressure vessel with overpressure protection in place. No credit was taken for active mitigation measures when evaluating this scenario. Therefore, the maximum allowable single vessel inventory allowed to release under established administrative controls is 161,339 pounds. This inventory is as sumed to vaporize and ignite, resulting in a vapor cloud explosion (VCE) which would result in a maximum distance to the 1-psi overpressure endpoint of .11miles. Process Safety Information The AIRI Lake Charles Refinery 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 treatment 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 areas, the chemical complex has documented safety related limits for specific process parameters (e.g. temperature, pressure, composition, etc.). The chemical complex ensures that the processes are maintained within these limits using process controls, monitoring instruments, protective instrument systems, and highly trained personnel. The chemical complex also maintains a database, that is accessible by both employees and contractor supervision, which provides information about the design and construction of process equipment. This information includes materials of construction, 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 evaluati ng proposed process and facility changes to ensure that safety features in the process are not comprised. Process Hazard Analysis The Lake Charles Refinery has a comprehensive program to help ensure the hazards associated with the various processes are identified and controlled. Within this program, each process is systematically examined to identify hazards and ensure that adequate controls are in place to manage these hazards. The Lake Charles refinery primarily uses the hazard and operability (HAZOP) analysis technique to perform these evaluations. HAZOP analysis is recognized as one of the most systematic and thorough hazard evaluation techniques. The analysis are 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 t he team believes such measures are necessary. The PHA team findings are made available to people associated with the process unit 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 are safely performed. At The Lake Charles Refinery, operating procedures: (1) are used to train employees and (2) serve as reference guides for appropriate actions to ta ke 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. Training The Lake Charles Refinery trains its workers to safely and effectively perform their assigned tasks. The training program includes both initial and refresher training. All new operators receive two weeks of comprehensive training before ever being assigned to a specific operating unit. This training includes training on specific types of equipment, such as pumps an d compressors, general overview of the process, properties and hazard substances in the process, detailed review of complex procedures, such as, safe work practices and emergency response. Oral reviews and written tests are used to verify that employees understand the training material before a new employee can report to a process unit. Once a new employee reports to a particular process unit, he receives detailed training with respect to process specific procedures. Once the new hire has demonstrated, through oral review and written tests, mastery of process specific operating procedures and for specific tasks, he is allowed to begin work in a specific operating unit. Refresher training covers (1) a general overview of the process, (2) the properties and hazards of the substances in the process and, (3) a detailed 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 Refinery 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 (PSSRs) The Lake Charles Refinery 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 is 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 Refinery 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 conditi on. The basic aspects of this program include (1) conducting training, (2) developing written procedures, (3) performing 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 functions as intended, and to verify 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 suc h time a final solution has been implemented and documented. Another integral part of the mechanical integrity program is quality assurance. The Lake Charles Refinery 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 Refinery has a long-standing 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 Refinery 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. The refinery trains employees to identify and report any incident requiring investigation. The investigation is initiated within 48 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 Refinery 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 PHAs (Process Hazard Analysis) and operating procedures. Compliance Audits The Lake Charles Refinery 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 Lake Charles Refinery. Contractors The Lake Charles refinery 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 plants safe work practices, and the plants emergency response procedures. The plant requires that the contractor supervisors train each of their employees on hazards and procedures specific to the complex site. The plant periodically reviews contractors training documents and work performances to help ensure that safe practices are followed. Five Year Accident History The facility has experienced no events in the period of June 1994 to present, which had offsite impact.
