Pactiv Corporation - Executive Summary
Risk Management Plan
1. Accidental Release Prevention and Emergency Response Policies
We at Pactiv Corporation are strongly committed to employee, public and environmental safety. This commitment is inherent in a comprehensive accidental release prevention program that covers areas such as design, installation, operation, and maintenance of the processes at our facility. It is our policy to implement appropriate controls to prevent possible releases of regulated substances and to train employees regarding the safe operation of processes involving regulated substances. Although such an event is unlikely, employees are trained to react to unplanned releases of regulated substances. In addition, the plant has coordinated with local and other emergency response organizations which provide highly trained emergency response personnel to help control and lessen the effects of any unplanned release.
2. The Stationary Source and the
The primary manufacturing activity at this plant involves the production of plastic consumer products such as polystyrene foam plates, bowls, food containers, and trays that you might find meat or poultry on in a supermarket. We have one substance present at our facility which is regulated by United States Environmental Protection Agency (USEPA) under the Risk Management Program. This substance is iso-pentane; and is referenced in this document by the term "regulated substance". The regulated substance at our facility is used as foaming agents in the production of the polystyrene foam. These products are also often called "blowing agents" or "expansion agents" .
The maximum inventory of iso-pentane possible at our facility is approximately 360,000 pounds. Written operating procedures and high-level alarms prevent more than this amount from being present at this facility.
3. Worst Case Release Scenario(s) and Alternative Release Scenario(s), including admini
strative controls and mitigation measures to limit the distances for each reported scenario
Under RMP, USEPA requires facilities to determine the effects of catastrophic releases of regulated substances. In facilities which use flammable regulated substances, USEPA defines the worst case scenario for a catastrophic release to be 1 pound per square inch (psi) over-pressure as a result of an instantaneous release of the largest tank volume utilizing no active measures to control the release of the regulated substance under worst-case weather conditions. USEPA defines alternative release scenarios as 1 psi over-pressure as a result of a timed release of a portion of the largest tank volume utilizing active measures to control the release of the regulated substance under neutral weather conditions.
To evaluate the worst case scenario for the particular regulated substances and conditions at this facility, we used equations from Appendix D of the USEPA RMP Offsite Consequence Analysi
s Guidance and RMP Compute, a simplified EPA model based on the EPA?s Offsite Consequence Analysis Guidance. For analysis of alternative release scenarios, we also employed the equations provided by the USEPA in the RMP Offsite Consequence Analysis Guidance and RMP Compute. The following paragraphs provide details of the chosen scenarios.
The activities at the plant can be categorized by Program 3 of the RMP guidance. The projected worst case release scenario would involve a catastrophic release from the iso-pentane storage. The scenario involves the release of 170,000 pounds of iso-pentane. Passive mitigation systems such as dikes were not considered when evaluating this scenario. The worst case release scenario assumes that the entire quantity of the iso-pentane storage tank is released as a vapor, an ignition source is present and 10 percent of the released quantity participates in a vapor cloud explosion. Under worst case weather conditions, the maximum distance of 0.40 mil
es corresponds to an endpoint of 1 psi overpressure.
The alternative release scenario involves a release from the iso-pentane storage tank assumed to result in a pool fire. The scenario involves the release of 26,000 pounds of iso-pentane. The release is controlled by active mitigation measures that include a deluge system and an automatic shut off valve. Under neutral weather conditions, the maximum distance from the center of the pool where people can potentially receive second degree burns from a 40-second exposure is 0.11 miles.
4. The General Accidental Release Prevention Program and the Chemical-Specific Prevention Steps
Our facility has taken all the necessary steps to comply with the accidental release prevention requirements set out under EPA?s 40 CFR Part 68. This facility was designed and constructed in accordance with NFPA-58 Standard, 1967 Edition. A number of processes at our facility are subject to the OSHA PSM standard under 29 CFR 1910.119. We also have an ai
r operating permit under Title V of the Clean Air Act. This facility has received a Star Ranking under OSHA?s Voluntary Protection Program (VPP) for over ten (10) years. The following sections briefly describe the elements of the release prevention program that are in place at our stationary source.
Process Safety Information
Pactiv Corporation maintains a detailed record of safety information that describes the chemical hazards, operating guidelines and equipment designs associated with the processes.
Process Hazard Analysis
Our facility conducts extensive studies to ensure that hazards associated with our processes are identified and controlled efficiently. The approach used to carry out these analyses is a HAZOP/Modified What If process. The studies are undertaken by a team of qualified personnel with expertise in engineering, process operations, and safety and are revalidated at a regular interval of approximately every 5 years. Seismic activity consequences and prevention ac
tivities are considered during HAZOP studies. Any findings related to the hazard analysis are addressed in a timely manner.
For the purposes of safely conducting activities within our covered processes, Pactiv Corporation maintains written operating procedures. These procedures address various modes of operation such as initial startup, normal operations, temporary operations, emergency shutdown, emergency operations, normal shutdown and startup after a turnaround. The information is regularly reviewed and is readily available to operators involved in the processes.
Pactiv Corporation utilizes a detailed training program to ensure that employees who are operating processes using regulated substances are skilled in the handling, operation, and maintenance procedures associated with these processes. Refresher training is provided at least every one (1) years and more frequently as needed.
Pactiv Corporation carries out routine,
periodic maintenance inspections and preventive maintenance on process equipment to ensure proper operations. Process equipment examined these inspections include but are not limited to pressure vessels, storage tanks, piping systems, relief and vent systems, emergency shutdown systems, controls and pumps. Maintenance operations are carried out by qualified personnel with training in maintenance practices. These personnel are provided specialized training as needed. Any equipment deficiencies identified by maintenance inspections are corrected in a safe and timely manner.
Management of Change
Written procedures at Pactiv Corporation are in place to manage changes in process chemicals, technology, equipment and procedures. Process operators, maintenance personnel or any other employee whose job tasks are affected by a modification in process conditions are promptly made aware of changes and provided training, as needed, to deal with these changes.
Pre-startup Safety Reviews
-start up safety reviews related to new processes and to modifications in established processes are conducted as a regular practice at Pactiv Corporation. These reviews are conducted to confirm that equipment and procedures are complete and suitable for safe startup prior to placing equipment into operation.
Pactiv Corporation conducts audits on a regular basis to determine whether the requirements set out under the RMP rule are being implemented. These audits are carried out at least every 3 years and any corrective actions required as a result of the audits are undertaken in a safe and prompt manner.
Pactiv Corporation promptly investigates any incident that results in, or could reasonably result in a catastrophic release of a regulated substance. These investigations are undertaken to identify the situation leading to the incident as well as any corrective actions to prevent a potential release from reoccurring. Reports are kept for a m
inimum of 5 years.
Pactiv Corporation truly believes that process safety management and accident prevention is a team effort. Company employees are strongly encouraged to express their views concerning accident prevention issues and to recommend improvements. Many employees participate in safety initiatives within the plant. In addition, our employees have access to all information created as part of our facility?s implementation of the RMP rule, including information resulting from process hazard analyses, in particular.
On occasion, our company hires contractors to conduct specialized maintenance and construction activities. Prior to selecting a contractor, a thorough evaluation of the contractor?s safety performance and program is carried out. Pactiv Corporation has a strict policy of informing contractors of known potential hazards related to the contractor?s work and the processes. Contractors are also informed of the procedures for emerg
ency response should an accidental release of a regulated substance occur.
The facility maintains a hot work program and issues a hot work permit for hot work conducted on or near the covered process. Hot work is performed by qualified personnel who complete each permit and fulfill its requirements prior to the start of a hot work operation. These permits are kept on file until the conclusion of the hot work operation.
