Georgia-Pacific Resins, Inc. - Executive Summary
1. EXECUTIVE SUMMARY |
Georgia-Pacific Resins, Inc. (GPRI), a wholly owned subsidiary of Georgia-Pacific Corporation, owns and operates a synthetic resin manufacturing facility in Vienna, GA. The facility is located on 7th Street and is adjacent to another Georgia-Pacific Corporation plant which manufactures particleboard. The resin facility consists of two plants: a resin plant that was originally constructed in 1970 and a plant that manufactures formaldehyde, which is one of the basic raw materials used to manufacture the resins. This formaldehyde plant was constructed in 1971. Overall, the facility employs 54 full-time employees.
GPRI is committed to operating the Vienna, Georgia plant in a manner that is safe for its workers, the public, and the environment. As part of this commitment, GPRI 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
at the Vienna Plant 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 a risk management plan (RMP Plan) describing the risk management program at the Vienna Plant. This document is intended to satisfy the RMP Plan requirement of the RMP rule and to provide the public with a description of the risk management program at the Vienna Plant.
The risk management program at the Vienna Plant consists of the following three elements:
7 a hazard assessment to help understand (a) the potential offsite consequences of hypothetical accidental releases and (b) accidents that have occurred during the last five years associated with the use of substances regulated by the RMP rule (regulated substances).
7 a prevention program to help maintain and safely operate the processes containing more t
han a threshold quantity of a regulated substance (covered processes).
7 an emergency response program to help respond to accidental releases of regulated substances from covered processes
Information further describing these elements is provided in this RMP Plan.
Although the risk management program at the Vienna Plant helps provide assurance that the facility is maintained and operated in a safe manner, it is only one component of the safety program at the Vienna Plant. In fact, the Vienna Plant has a comprehensive safety program in place establishing many levels of safeguards against release of a hazardous substance and injuries and damage from a release of a hazardous substance.
GPRI limits the use of hazardous substances. Before using a hazardous substance at the Vienna Plant, less hazardous alternatives are considered. When a hazardous substance is used at the Vienna Plant, GPRI considers the potential for this substance to adversely affect plant workers, the public, an
d the environment and takes steps to prevent any such effects.
GPRI prevents releases of the hazardous substances used at the facility. When a hazardous substance is used at the Vienna Plant, the equipment 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.
GPRI limits damage from a release, if such a release occurs. GPRI trains its workers to respond to an accidental release, reducing the consequences of a release if it occurs. In addition, GPRI works with the local fire department and with the local emergency planning committee (LEPC) to help prevent injuries and/or environmental damage if a release does occur.
The safety program at the Vienna Plant consists of a number of elements, only some of which are required by the RMP rule. This RMP Plan is primarily intended to describe those parts of the safety program at the
Vienna Plant that are required by the RMP rule.
1.1 Accidental Release Prevention and Emergency Response Policies
GPRI 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. GPRI implements reasonable controls to prevent foreseeable releases of hazardous substances. These controls include training programs for personnel, programs to help ensure safety in the design, installation, operation, and maintenance of processes at the Vienna Plant; and programs to evaluate the hazards at the plant.
In the event of an accidental release, the Vienna Plant controls and contains the release in a manner that will be safe for workers and will prevent injury to the public and the environment. GPRI provides response training to its personnel, designates an emergency response coordinator to oversee response activities, and coordinates response efforts with the local fire department.
Response activities have also been discussed with the LEPC.
In order to effectively implement these policies, GPRI established a management system headed by the Safety Manager to oversee safety-related activities.
1.2 Regulated Substances
The Vienna Plant handles two regulated substances in sufficient quantity to be covered by the RMP rule, as shown in the following list of RMP-covered Program Level 3 processes at the plant.
Regulated Substance Process Process Quantity*, lbs RMP Threshold, lbs*
Formaldehyde Solution (50%) Storage in Unpressurized, Heated Tanks 604,210 15,000
Formaldehyde Solution (50%) Resin Manufacturing 51,100 15,000
Aqueous Ammonia (28%) Storage in Unpressurized Tanks 21,000 20,000
* Process and threshold quantity is the quantity of "pure" chemical, not of the solution
1.3 Offsite Consequence Analysis
The Vienna Plant performed an offsite consequence analysis to estimate the potential for an accidental release of a regulated subs
tance to affect the public or the environment. The offsite consequence analysis evaluates a "worst-case release scenario" and an "alternative release scenario". GPRI does not expect a worst-case release scenario to ever occur. The alternative release scenarios were selected to help the LEPC improve the community emergency response plan. An alternative release scenario represents a release that (1) might occur at a facility like the Vienna Plant and (2) would result in the greatest potential offsite consequences if the release occurred.
The main objective of 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). The following effects could occur at the endpoint distance. At distances less than the endpoint distance, the effects would be greater; at distances greater than the endpoint distance, the effects would be less.
1.3 Offsite Consequence
When considering the release of a toxic substance, 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 possible. Some people who are particularly susceptible to the substance released could be incapacitated.
The RMP rule includes specific requirements for the worst-case and alternative release scenarios that must be reported by GPRI. These requirements are:
7 one worst-case release scenario for the class of toxic substances in Program 3 processes
7 one alternative release scenario for each of the toxic substances in a Program 3 process
7 one worst-case and one alternative release scenario for the class of flammable substances in Program 3 processes
The following information summarizes the offsite consequence analysis performed by the Vienna Plant:
1.3.1 Program 3 Processes-Toxic Substances- Aqueous A
mmonia and Formaldehyde Solutions
The "worst-case release scenario" for a 28% solution of ammonia is the instantaneous release of the entire contents of a 10,000 gallon (21,000 lbs of pure ammonia-20,000 lb threshold) storage tank in the resin manufacturing process. A concrete diked area contains the released ammonia solution which evaporates and forms a vapor cloud. The maximum distance to the toxic endpoint concentration based on modeling is 2.3 mile. The U.S. Census indicates that 3,440 people live within this distance from the location of the storage tank; several public receptors are also located within this distance, including the adjacent Georgia-Pacific Corporation Particleboard Plant, nearby residences, and the Dooly County Hospital. No environmental receptors are located within this distance.
The "alternative case release scenario" for a 28% solution of ammonia is the overfilling of an ammonia solution storage tank and the spillage of 600 gallons (1,260 lbs of pure am
monia) of solution into the concrete diked area. Modeling this scenario indicates a toxic endpoint distance of 0.3 mile. The U.S. Census indicates that 49 people live within this distance from the storage tank; several public receptors are also located within this distance, including the adjacent Georgia-Pacific Corporation Particleboard Plant, and nearby residences. No environmental receptors are located within this distance.
1.3.1 Program 3 Processes (Con't)
The "worst-case release scenario" for a 50% solution of formaldehyde is the release of the entire contents of a 100,000 gallon (940,000 lbs of pure formaldehyde) storage tank. A concrete diked area contains the released formaldehyde solution which evaporates and forms a vapor cloud. The maximum distance to the toxic endpoint concentration based on modeling is 0.45 mile. The U.S. Census indicates that ?317? people live within this distance from the location of the storage tank; several public receptors are also located wi
thin this distance, including the adjacent Georgia-Pacific Corporation Particleboard Plant, nearby residences, and the Dooly County Hospital. No environmental receptors are located within this distance.
The "alternative case release scenario" for a 50% solution of formaldehyde is the overfilling of a formaldehyde storage tank and the spillage of 1,000 gallons (4,800 lbs of pure formaldehyde) of solution into the concrete diked area. Modeling this scenario indicates a toxic endpoint distance of 0.2 mile. The U.S. Census indicates that 20 people live within this distance from the storage tank; several public receptors are also located within this distance, including the adjacent Georgia-Pacific Corporation Particleboard Plant, and nearby residences. No environmental receptors are located within this distance.
1.3.2 Program 3 Processes-Flammable Substances
There are no regulated flammable substances in quantities above the threshold quantities at the plant. Propane is stored o
n-site in a 1,000 gallon (4,400 pound) storage tank, however, this quantity is less than the threshold quantity of 10,000 pounds.
1.4 Accidental Release Prevention Program and Chemical-Specific Prevention Steps
Since 19xx, the Vienna Plant has used a prevention program to help prevent accidental releases of hazardous substances. Beginning in 1992, the plant formalized this prevention program for the formaldehyde manufacturing and storage process to comply with the 14 elements of the OSHA process safety management (PSM) prevention program. In 1996, the EPA RMP rule established two levels of prevention requirements:
Program 3-essentially the same as OSHA PSM, except that the program also focuses on protecting the public and the environment
Program 2-requires simplified versions of 7 of the 12 elements of the Program 3 prevention program (not applicable for Vienna Plant)
The following sections briefly describe the elements of the Vienna Plant's Program 3 prevention program
that address EPA's RMP rule prevention program requirements.
1.4.1 Program 3 Prevention Program
The Vienna Plant's Program 3 prevention program consists of the following 12 elements:
126.96.36.199 Process Safety Information-the Vienna Plant maintains a variety of technical documents that are used to help ensure safe operation of the plant processes. These documents address (1) physical properties of hazardous substances handled at the plant, (2) operating parameters of the equipment used at the plant, and (3) design basis and configuration of the equipment at the plant. GPRI ensures that this process safety information is available to all employees, the LEPC, the Vienna Volunteer Fire Department, the Dooly County Medical Center, and the Dooly County Sheriff's Office.
Material safety data sheets (MSDSs) document the physical properties of the hazardous materials handled at the plant, including regulated substances in covered processes. The information available for each hazardous
substance typically includes:
7 toxicity information and permissible exposure limits
7 physical data (e.g., boiling point, melting point, flash point)
7 reactivity and corrosivity data
7 thermal and chemical stability data
7 hazards of mixing substances in the process
MSDSs for hazardous substances handled in each process are available in the process control room so that the operators have ready reference to this information. In addition, MSDSs are provided to the LEPC and the fire department for use in helping formulate emergency response plans.
The engineering design documents include the operating parameters and the design basis and configuration of the equipment in each covered process. The available information includes:
7 operating parameters
7 block flow or simplified process flow diagrams
7 process chemistry
7 maximum intended inventories
7 safe upper and lower limits for parameters such as temperature, pressure, or flow
7 consequences of deviations from establi
shed operating limits
7 design basis and configuration of equipment
7 piping and instrumentation diagrams, including materials of construction
7 electrical classification
7 safety systems
7 applicable design codes and standards
7 design basis for relief and ventilation systems
188.8.131.52 Process Safety Information (Con't)
When important information was not available, from the design documents, it was developed through special projects or, in the case of operating parameters, during process hazard analyses of the process. Many of the operating parameters are included in the operating procedures to help with the safe operation of the process. These documents are used to (l) train employees, (2) perform process hazards analyses, (3) evaluate process changes, and (4) help maintain the equipment.
184.108.40.206 Process Hazard Analysis
The Vienna Plant performs and periodically updates process hazard analyses (PHAs) of the covered processes to help identify process hazards and generate re
commendations that might improve the safe operation of the process. A team composed of personnel with engineering and process operating experience and a leader with process hazard analysis experience is assembled to analyze the hazards of the process. The plant primarily uses the "what-if /checklist" in combination with HAZOP guidewords PHA methodology to perform this analysis. The PHA team 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.
220.127.116.11 Operating Procedures
Vienna Plant 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 (1) are used to train employees and (2) serve as reference guides for appropriate
actions to take during both normal operations and process upsets. Operating procedures include:
7 steps for safely conducting activities
7 applicable process safety information, such as safe operating limits and consequences of process deviations
7 safety and health considerations, such as chemical hazards, personal protective equipment requirements, and actions to take if exposure to a hazardous substance occurs
Plant personnel develop and maintain operating procedures that cover all phases of operations, including initial startup, normal operations, normal shutdown, emergency shutdown, startup following a turnaround or emergency shutdown, and temporary operations. The operating procedures are used both to help in operating the plant's processes and as a training guide.
The Vienna Plant trains its workers to safely and effectively perform their assigned tasks. The training program includes both initial and refresher training that covers (1) a general ove
rview 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. Computer-based training modules, classroom training, and on-the-job training with experienced operators are used to conduct this training. Oral reviews and written tests are used to verify that an employee understands the training material before the employee can resume work in the process. The operators are consulted annually at safety meetings to evaluate the effectiveness and frequency of the training. Refresher training is conducted on a minimum of every three (3) years. Recommendations from the operators are reviewed, and changes to the training program are implemented as appropriate.
18.104.22.168 Mechanical Integrity
The Vienna Plant maintains the mechanical integrity of process equipment to help prevent equipment failures that could endanger workers, the public, or the environment. The mechanical inte
grity program includes (1) an inspection and testing 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 meets the design standards required for service in the plant's processes. The mechanical integrity program includes:
7 specifications for inspection and testing of process equipment
7 specifications for replacement parts and equipment
7 procedures for inspecting, testing, and maintaining process equipment
7 procedures for safe work practices such as lockout/tagout, hot work, confined space entry, and line or equipment opening
7 training of maintenance personnel
7 documentation of maintenance activities
22.214.171.124 Management of Change
The Vienna Plant management of change program evaluates and approves all proposed changes to chemicals, equipment, and procedures for a covered process to help ensure that the 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 the full management of change program to help 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.
126.96.36.199 Pre-startup Review
The Vienna Plant performs a safety review of a new or modified process before the process is placed into service to help ensure that the process has been prepared to operate safely. This review confirms that:
7 construction and equipment are in accordance with design specifications
7 adequate safety, operating, maintenance, and emergency procedures are in place
7 employee training has been completed
7 for a covered process, a PHA has been performed if th
e process is new or management of change requirements have been completed if an existing process has been modified
A pre-startup review checklist is completed to document the review and to ensure that appropriate issues have been addressed.
188.8.131.52 Compliance Audit
The Vienna Plant audits covered processes to be certain that the prevention program is effectively addressing the safety issues of operations at the plant. The plant assembles an audit team that includes personnel knowledgeable in the RMP rule and in the process, and this team evaluates whether the prevention program satisfies the requirements of the RMP rule and whether the prevention program 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.
184.108.40.206 Incident Investigation
The Vienna Plant investigates all incidents that could reasonably have resulted in a s
erious injury to personnel, the public, or the environment so that similar accidents can be prevented in the future. The plant trains 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 enhancements are implemented.
220.127.116.11 Employee Participation
The Vienna Plant developed a written employee participation program for all covered processes to help ensure that the safety concerns of the plant's workers are addressed. The plant encourages active participation of personnel in the prevention program activities of all processes at the plant. Employees are consulted on, and informed about, all aspects of the RMP rule prevention program, including PHAs and operating procedures.
18.104.22.168 Hot Work Permits
The Vienna Plant established a hot work permit progra
m to control spark- or flame-producing activities that could result in fires or explosions in covered processes at the plant. The plant reviewed OSHA's fire prevention and protection requirements in 29 CFR 1910.252(a) 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 Shift Supervisor reviews the completed form before work can begin. Training in the use of the Hot Work Permit Form is included in the plant's safe work practices orientation.
The Vienna Plant established a program to help ensure that contractor activities at the plant are performed in a safe manner. The program reviews the safety record of all contractors to help ensure that the plant only hires contractors who can safely perform the desired job tasks. The plant explains to the contract supervisors 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 who will work at the plant before that worker begins work at the plant site. The plant periodically reviews contractors' training documents and work performance to help ensure that safe practices are followed.
1.4.2 Chemical-specific Prevention Steps
In addition to the required prevention program elements, the Vienna Plant has implemented safety features specific to the hazardous substances used at the plant. The following paragraphs describe some of these features.
Aqueous ammonia-Industry standards are followed at the plant to help ensure safe handling of aqueous ammonia. The ammonia vendor supplies aqueous ammonia via a Department of Transportation (DOT)- approved tank truck and follows DOT standards when loading the aqueous ammonia storage tank. The storage tank design and construction are consistent with American Nati
onal Standards Institute (ANSI) standards. Workers who perform operations involving ammonia receive training emphasizing safe handling procedures for ammonia developed by the plant. The storage tank is surrounded by a concrete dike which is large enough to contain 100% of the volume of the tank should its entire contents be spilled. A cooling system has been added to the tank to reduce the vapor pressure of the tank by keeping the contents of the tank below 82.5 oF / 28 oC which in turn maintains "atmospheric pressure" and the conservaion vent is set at 1 PSIG and .18psig vacuum. The tank is continuously circulated through the cooling system to maintain the temperature of the tank contents well below the 82.5 oF / 28 oC. When the tank is filled, a vapor balancing system is utilized which reduces ammonia vapors by 98%. When a truck is unloaded, it also passes through this cooling system to cool the contents of the the Ammonia being unloaded from the truck to keep the tank below the
82.5 oF / 28 oC.
1.4.2 Chemical-specific Prevention Steps (Con't)
Formaldehyde solution-Industry standards are followed at the plant to help ensure safe handling of formaldehyde. Most of the formaldehyde stored in the plant's storage vessels is piped directly from the formaldehyde plant. However, to make-up for shortfalls in formaldehyde production, some formaldehyde is delivered to the plant by offsite vendors. The formaldehyde vendor supplies formaldehyde solution via a DOT- approved tank truck and follows DOT standards when loading the formaldehyde storage tank(s). The storage tank(s) design and construction are consistent with ANSI standards. Workers who perform operations involving formaldehyde receive training emphasizing safe handling procedures for formaldehyde developed by the plant. The storage tank(s) is surrounded by a concrete dike which is large enough to contain 100% of the volume of the tank should its entire contents be spilled. All air emissions from the
storage tank(s) are directed to a thermal oxidizer which destroys >99% of the vapors.
1.5 Five-Year Accident History
The Vienna Plant has completed a five year accident history that indicates no off-site releases of toxic compounds.
1.6 Emergency Response Programs
The Vienna Plant has established a written emergency response program to help safely respond to accidental releases of hazardous substances. The emergency response plan includes procedures for the following:
7 informing the local fire department and the public about accidental releases that could reasonably result in offsite consequences
7 providing proper first aid and emergency medical treatment to treat accidental human exposure to hazardous substances at the plant
7 controlling and containing accidental releases of hazardous substances, including the use of emergency response equipment
7 inspecting and maintaining emergency response equipment
7 reviewing and updating the emergency response plan
he Vienna Plant maintains an emergency response team trained in these emergency response procedures. All plant personnel are trained in evacuation procedures. The plant periodically conducts emergency response drills, including annual drills coordinated with the local fire department. 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 has communicated to local emergency response officials through the local fire department. The plant maintains a regular dialogue with the local fire chief, and the plant provides appropriate information to the fire chief.
A copy of the plant's Emergency Response Plan is attached to this RMP Plan.
1.7 Planned Changes to Improve Safety
The Vienna Plant constantly strives to improve the safety of the processes at the facility through both the incident investigation program and a program soliciting safety suggestions from the workers.
The following changes to improve process safety are planned or have recently been completed.
7 Revalidation of PHAs will continue.
7 Creation of Standard Operating Procedures and Job Task Procedures will continue for procedures not within the covered process.
7 Operator training to increase with the use of Computer Based Training interactive modules for theory on current systems. Recertification of operating personnel will use the CBT training and hands on demonstrated ability checklists.
7 Permit auditing will increase on all types of work permits.
7 Previous emergency response drills such as fire and evacuation previously accomplished annually will be performed at a minimum, quarterly.
7 A combined exercise will be performed for emergency response with the local responding agencies.
7 Safety and Health Training will be supplemented by some "hands on" exercises.
7 Pre-Startup Safety Reviews will be performed on any major shut down prior to restarting the process.
7 Labeling of all equipment and piping will continue.
7 Variation Reduction program will continue for identification of "best practice" for implementation on the processes.
7 Application to the OSHA Voluntary Protection Plan will be explored to see if there will be added value in terms of safety for both employees and the community by our participation in this plan.
