EXECUTIVE SUMMARY FOR GULF STATES PAPER CORPORATION 
 
1.  EXECUTIVE SUMMARY 
Gulf States Paper Corporation (Gulf States) is committed to operating in a manner that is safe for our workers, the community, and the environment.  As part of this commitment, Gulf States has established a system to help ensure safe operation of the processes at this facility.  One component of this system is a risk management program (RMP) that helps manage the risks involved with using hazardous substances at Gulf States and that complies with the requirements of the Environmental Protection Agency's (EPA's) regulation 40 CFR part 68, Accidental Release Prevention Requirements: Risk Management Programs (the RMP rule).  One of the requirements of the RMP rule is to submit an executive summary in the risk management plan (RMPlan) describing the risk management program at Gulf States.  This document is intended to satisfy the executive summary requirement of the RMP rule and to provide the public with a descript 
ion of the risk management program at Gulf States. 
 
The risk management program at Gulf States consists of three elements: 
 
1. a hazard assessment designed to help us understand (a) the potential offsite consequences of hypothetical accidental releases and (b) accidents that have occurred during the last five years associated with the substances regulated by the RMP rule (regulated substances) - see topics 1.3 and 1.5 
2. a prevention program to help maintain and safely operate processes containing significant quantities of substances regulated by the RMP rule - see topic 1.4 
3. an emergency response program to help respond to accidental releases of regulated substances from processes covered by the RMP rule - see topic 1.6 
 
Information further describing these elements is provided in this executive summary. 
 
Although the risk management program at Gulf States helps ensure that our facility is maintained and operated in a safe manner, it is only one component of the safety program.  In  
fact, Gulf States has a comprehensive safety program that establishes many levels of safeguards against accidental releases and against the injuries and damage that could occur from accidental releases. 
 
Gulf States limits the use of hazardous substances.  Before using a hazardous substance, we always consider less hazardous alternatives.  When a hazardous substance is used at Gulf States, we consider the potential for this substance to adversely affect our workers, the public, and the environment and take steps to prevent any such effects. 
 
Gulf States prevents releases of the hazardous substances used at the facility.  When a hazardous substance is used, the equipment used to contain it is carefully designed, built, and operated to reduce the likelihood of an accidental release.  Industry and government standards are closely adhered to in the design, construction, and operation of the equipment. 
 
Gulf States limits damage from a release, if such a release occurs.  We work daily to pr 
event accidental releases from occurring.  However, we also train our workforce to respond to accidental releases and reduce the potential consequences.  In addition, Gulf States works with the local fire department and with the local emergency planning committee (LEPC) to help ensure that all emergency responders work closely together to minimize the impact of the release on our workers and the community. 
 
The safety program at Gulf States consists of a number of elements, only some of which are required by the RMP rule.  This RMPlan is primarily intended to describe those parts of the safety program at Gulf States that are required by the RMP rule. 
 
1.1 Accidental Release Prevention and Emergency Response Policies 
Gulf States is committed to the safety of workers and the public, and the preservation of the environment, through the prevention of accidental releases of hazardous substances.  Gulf States implements reasonable controls to prevent foreseeable releases of hazardous substan 
ces.  These controls include training programs for personnel; programs to help ensure safety in the design, installation, operation, and maintenance of processes at Gulf States; and programs to evaluate the hazards at Gulf States. 
 
In the event of an accidental release, Gulf States will strive to control and contain the release in a manner that will be safe for workers and will help prevent injury to the public or damage to the environment.  Gulf States provides response training to our personnel, designates the maintenance superintendent or his designee to oversee response activities, and coordinates response efforts with the local fire department and/or the LEPC.  Response activities have also been discussed with the LEPC. 
 
1.2 Gulf States Paper Corporation and the Regulated Substances We Use 
Gulf States is an integrated pulp and paperboard mill primarily involved in the manufacture of bleached pulp and related finished paperboard products.  As part of this manufacturing process, Gul 
f States handles two regulated substances in sufficient quantities to be covered by the RMP rule, as shown in the following list of RMP-covered processes at Gulf States. 
 
Process Regulated Substance(s) 
No. 1 Bleach Plant, Chlorine dioxide 
No. 2 Bleach Plant, Chlorine dioxide 
Chlorine Dioxide Plant, including the Cooling Tower, Chlorine dioxide 
Chlorine Railcars, Chlorine, including chlorine to the No. 1 Bleach Plant 
 
1.3 Offsite Consequence Analysis 
Gulf States performed an offsite consequence analysis to estimate the potential for accidental releases of regulated substances that could affect the public or the environment. We evaluated both worst-case release scenarios and more reasonable (but still highly unlikely) alternative release scenarios for both chlorine and chlorine dioxide. 
 
Gulf States does not expect a worst-case release scenario to ever occur.  These scenarios are designed to estimate the maximum possible area that could be affected by a release at our facility, but they  
are not realistic scenarios.  The alternative release scenarios were selected to help the LEPC improve the community emergency response plan.  An alternative release scenario represents a release that might occur at a facility like Gulf States. 
 
The main objective for performing the offsite consequence analysis is to determine the distance at which certain effects might occur to the public because of an accidental release (called the endpoint distance). For exposures to chlorine and chlorine dioxide, most people at the endpoint distance would be able to walk away from the exposure without any long-term health consequences, although some short-term consequences (e.g., strong eye or throat irritation) are likely.  Some people who are particularly susceptible to the substance released could be incapacitated.  At distances less than the endpoint distance, the effects would be more severe; at distances greater than the endpoint distance, the effects would be less severe. 
 
The following info 
rmation summarizes the offsite consequence analyses performed by Gulf States.  
 
1.3.1 Worst-case release scenarios for chlorine and chlorine dioxide 
The worst-case release scenario for chlorine is a failure of a 90-ton chlorine railcar in the Chlorine Railcar process.  This type of scenario is extremely rare, but we further assume, as required by EPA, that (1) the railcar is full at the time of the rupture and (2) all of the chlorine in the tank is released as a gas over 10 minutes.  The distance to the toxic endpoint of chlorine (3 ppm) for this scenario is more than 25 miles from the facility.  The U.S. Census indicates that 44,000 people live within this distance from the railcar unloading area.  There are two environmental receptors within this distance:  the Demopolis Wildlife Management Area and the Kinterbish Wildlife Management Area.  There are also many types of public receptors such as schools, residences, hospitals, public recreational areas, one large jail in the Linden are 
a, and several commercial industrial areas. 
The worst-case release scenario for chlorine dioxide is a failure of a chlorine dioxide storage tank.  Although the storage tank is quite large (132,000 gallons), it contains about 99% water and 1% chlorine dioxide.  Even so, when we assume that (1) the storage tank is full and (2) all the chlorine dioxide is released over 10 minutes, the predicted endpoint distance to the toxic endpoint (1 ppm) is more than 25 miles from the storage tank. The U.S. Census indicates that 44,000 people live within this distance from the chlorine dioxide stoarge tanks. There are two environmental receptors within this distance:  the Demopolis Wildlife Management Area and the Kinterbish Wildlife Management Area.  There are also many types of public receptors such as schools, residences, hospitals, public recreational areas, one large jail in the Linden area, and several commercial industrial areas. 
 
1.3.2 Alternative release scenarios for chlorine and chlorine di 
oxide 
The alternative release scenario for chlorine is an unloading hose rupture on a 90-ton chlorine railcar. Although this is more realistic than the worst-case scenario, Gulf States is aware of the potential for this accident and has put great effort into minimizing the risk associated with this process.  For example, color video cameras, remotely operated block valves, and chlorine sensors that feed into the control room are always monitoring the unloading areas so that our employees can shut off a release quickly.  In addition, the chlorine railcars are equipped with excess flow valves that automatically shut off the release if the release rate exceeds a threshold rate.  In this scenario, we assume it takes 10 minutes to respond to the release, although this is probably longer than would actually be required.  The maximum distance to the toxic endpoint is 1.2 miles.  The U.S. Census indicates that 62 people live within this distance from the railcars.  No environmental receptors a 
re located within this distance; however, there are public receptors within 1.2 miles, including the Tombigbee River (used for recreational purposes), several residences, the McClain of Alabama facility, and one church (the Moscow Providence Church). 
 
The alternative release scenario for chlorine dioxide is a rupture of an expansion joint in an 8-inch pipe designed to transfer chlorine dioxide solution from the storage tank to the bleaching process.  This scenario assumes that the solution is released through the hole for 10 minutes before workers detect the release and isolate the line.  The released chlorine dioxide solution forms a pool and the chlorine dioxide evaporates from the pool, forming a vapor cloud.  The area around the chlorine dioxide storage tank is graded so that any spill is directed toward the mill's process sewer system; helping reduce chlorine dioxide in the area.  The maximum distance to the toxic endpoint is 1.2 miles.  The U.S. Census indicates that 62 people li 
ve within this distance from the railcars.  No environmental receptors are located within this distance; however, there are public receptors within 1.2 miles, including the Tombigbee River (used for recreational purposes), several residences, the McClain of Alabama facility, and one church (the Moscow Providence Church). 
 
1.4 Accidental Release Prevention Program and Chemical-specific Prevention Steps 
Gulf States has always believed that safety is the highest priority.  Beginning in 1992, Gulf States formalized this belief into a prevention program that complies with the OSHA process safety management (PSM) prevention program.  For Gulf States, the prevention program requirements for EPA's RMP rule are nearly identical to the PSM rule.  The following sections briefly describe the elements of Gulf States' prevention program that address the RMP rule prevention program requirements.  
 
1.4.1 Gulf States' Prevention Program 
The Gulf States accident prevention program, consists of the follo 
wing 12 elements: 
 
1. Process Safety Information.  Gulf States maintains a variety of technical documents, including an emergency preparedness plan, to help ensure that our employees and local emergency responders are knowledgeable about the hazards associated with our facility.  These documents address (1) physical properties of the hazardous substances we handle, (2) operating parameters for our equipment, and (3) design basis and configuration for our equipment.  Gulf States ensures that this process safety information is available to all our employees. 
 
2. Process Hazard Analysis.  Gulf States performs and periodically updates process hazard analyses (PHAs) of our covered processes to help identify process hazards and generate recommendations that might improve the safe operation of the process.  A team consisting of personnel with engineering and process operating experience and a leader with PHA experience is assembled to analyze the hazards of our processes.  The team painstakin 
gly addresses the potential hazards associated with each piece of equipment, down to the smallest pipe, that carries hazardous material. The PHA team then prepares a written report describing the results of the analysis, including a list of recommendations.  Responsibility to resolve the recommendations is assigned to unit personnel and, when appropriate, changes to enhance the safety of the process are implemented.  PHAs are revisited every five years to ensure they are current. 
 
3. Operating Procedures.  Gulf States' process engineers, operators, and supervisors work together to develop and maintain operating procedures to define how tasks related to process operations should be safely performed.  The 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 and consequences of process deviations 
? safety and health considerations, such as chemical hazards, personal protective equipment requirements, and actions to take if exposure to a hazardous substance occurs 
 
4. Training.  Gulf States trains workers to safely and effectively perform their assigned tasks.  Our training program includes both initial and refresher training that 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 reviews and written tests are used to verify that an employee understands the training material before the employee can begin or resume work in the process. 
 
5. Mechanical Integrity.  Gulf States maintains mechanical process equipment to help prevent equipment failures that could endanger workers, the public, or the environment.  Our mechanical integrity program includes (1) an inspection and test 
ing program to help identify equipment deterioration and damage before the equipment fails and (2) a quality assurance program to help ensure that new and replacement equipment meet the strict design standards required for service in our processes. 
 
6. Management of Change.  We evaluate and specifically approve all proposed changes to chemicals, equipment, and procedures to help ensure that the change does not negatively affect safe operations. All changes other than replacement-in-kind (e.g., replacing a valve with an identical valve) must be confirmed through the full management of change program.  This helps ensure that inadvertent consequences of process changes are prevented, safety consequences of changes are addressed, affected process safety information and procedures are updated, and affected employees are notified of the changes. 
 
7. Pre-startup Review.  Gulf States recognizes that new or newly modified processes are historically more likely to be involved in accidental relea 
ses.  Therefore, we perform safety reviews of new or modified processes before placing them into service to help ensure their safe operation.  This review confirms that: 
? construction and equipment are in accordance with design specifications 
? adequate safety, operating, maintenance, and emergency procedures are in place 
? employee training has been completed 
? for a covered process, a PHA has been performed if the process is new or management of change requirements have been completed if an existing process has been modified 
 
8. Compliance Audit.  One of the cornerstones of an effective prevention program is a regular, thorough assessment.  We audit our covered processes every three years to be certain our prevention program is effectively addressing the safety issues of Gulf States operations.  We assemble an audit team that includes personnel knowledgeable in the PSM and RMP rules and in our process designs, and this team evaluates whether the prevention program satisfies the requ 
irements of these two rules and whether it is sufficient to help ensure safe operation of the process.  The results of the audit are documented, recommendations are resolved, and appropriate enhancements to the prevention program are implemented. 
 
9. Incident Investigation.  Gulf States investigates all incidents that could reasonably have resulted in a serious injury to personnel, the public, or the environment so that similar accidents can be prevented in the future.  We train our employees to identify and report any incident requiring investigation.  An investigation team is assembled, and the investigation is initiated within 48 hours of the incident. The results of the investigation are documented, recommendations are resolved, and appropriate process improvements are implemented. 
 
10. Employee Participation.  Gulf States has a written employee participation program for covered processes to help ensure that the safety concerns of our workers are addressed.  We encourage active par 
ticipation of personnel in the prevention program activities of all processes at the facility.  Employees are consulted on and informed about all aspects of our accidental release prevention program. 
 
11. Hot Work Permits.  Gulf States has a hot work permit program to control spark- or flame-producing activities that could result in fires or explosions in our facility.  We reviewed OSHA's fire prevention and protection requirements and created a Hot Work Permit Form to comply with these requirements.  Personnel who are to perform hot work are required to fill out the Hot Work Permit Form.  The appropriate supervisor reviews the completed form before work can begin.  Training in the use of the Hot Work Permit Form is included in our safe work practices orientation. 
 
12. Contractors.  We have a program in place to help ensure that contractor activities at our facility are performed in a safe manner.  This program reviews the safety record of all our contractors to help ensure that we hir 
e only contractors who can safely perform the desired job tasks.  We explain to the contract supervisors the hazards of the processes on which they and their employees will work, our safe work practices, and our emergency response procedures.  We require that the Contractor Supervisors train each of their employees who will work at the facility before that worker begins work at our facility.  Gulf States periodically reviews contractors' training documents and work performance to help ensure that safe practices are followed.  
 
1.4.3 Chemical-specific Prevention Steps 
In addition to the required prevention program elements, Gulf States has implemented safety features specific to the hazardous substances used at our facility.  The following paragraphs describe some of these safety features. 
Chlorine.  Chlorine is supplied in 90-ton railcars that are approved by both the Department of Transportation and the Chlorine Institute.  Chlorine is fed through a short length of flexible hose into  
process piping.  From there, it is transferred through a vaporizer into the bleach plant where it is used for bleaching.  If a release occurs in the chlorine piping or hose, the excess flow valve in the railcar will reduce, if not stop, the flow into the atmosphere.  Also, the chlorine unloading area is always monitored in the control room by color video cameras set up outside, so that operators can quickly respond to a release through remotely operated block valves.  In addition, we have installed permanently mounted chlorine sensors at both railcars to alert operators of even small chlorine leaks. 
Chlorine Dioxide.  Chlorine dioxide is produced at the Gulf States facility and stored in a mixture that is 99% water and 1% chlorine dioxide.  This avoids the necessity of transporting large quantities of the solution, and storing this substance as a solution helps to reduce the consequences of a release.  Any release of chlorine dioxide that does occur will quickly wash into the process s 
ewer, where it will be mixed, diluted, and treated by a scrubber. 
 
1.5 Five-Year Accident History 
Gulf States has compiled a five-year accident history that indicates continuous safe operation over the last five years.  All five recorded accidental releases resulted in exposing one or more employees to a toxic vapor.  Although several of these employees became ill as a result of this exposure, no long-term impairment has resulted.  The number of accidental releases has generally been decreasing over the last five years.    
 
Year - Number of Reported Accidents - Substance Released - Consequences 
1995 - 1 Chlorine - Chlorine inhalation - one employee injured 
1996 - 1 Chlorine & 2 Chlorine dioxide - Chlorine and Chlorine dioxide inhalation - four employees injured 
1997 - None 
1998 - 1 Chlorine dioxide - Chlorine dioxide inhalation - two employees injured 
1999 - 2 - Chlorine and Chlorine dioxide inhalation - three contractors injured 
 
1.6 Emergency Response Programs 
Gulf States has establi 
shed a written emergency response program to help safely respond to accidental releases of hazardous substances.  The emergency response plan includes procedures for: 
? informing the LEPC about accidental releases that could reasonably result in offsite consequences 
? providing proper first aid and emergency medical treatment for accidental human exposure to hazardous substances 
? controlling and containing accidental releases of hazardous substances, including the use of emergency response equipment 
? inspecting and maintaining emergency response equipment 
? reviewing and updating the emergency response plan 
 
At Gulf States, maintenance teams are trained to respond to emergency situations and the maintenance superintendent is in charge of coordinating emergency actions.  All Gulf States personnel are trained in evacuation procedures.  The Director of Technical and Environmental Services is responsible for apprising the Marengo County LEPC of the emergency situation, and the LEPC is re 
sponsible for notifying the public, if necessary. 
 
The written emergency response plan complies with other federal contingency plan regulations (e.g., the OSHA regulations 29 CFR 1910.38(a), 29 CFR 1910.120(a)), and a copy of the plan has been provided to the LEPC and the fire department.  Gulf States maintains a regular dialogue with local emergency planners. 
 
1.7 Planned Changes to Improve Safety 
Gulf States constantly strives to improve the safety of processes at Gulf States using recommendations developed through the prevention program and a program soliciting safety suggestions from our employees.  The following changes to improve process safety are planned or have recently been completed: 
? Due to recently implemented environmental regulations, Gulf States has removed chlorine from the No. 2 Bleach Plant and will remove it from the No. 1 Bleach Plant later part of 2000.  This change will significantly reduce the overall risk to the public and the environment, both by reducing the 
potential impact of an accidental release on the community and by removing equipment that handles hazardous materials.
