BP Amoco-Wood River Facility - Executive Summary |
|
ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES At the BP Amoco-Wood River Facility, we are committed to operating and maintaining all of our processes (especially those using hazardous substances) in a safe and responsible manner. We use a combination of accidental release prevention programs and emergency response planning programs to help ensure the safety of our employees and the public as well as protection of the environment. This document provides a brief overview of the comprehensive risk management activities that we have designed and implemented, including: * A description of our facility and use of substances regulated by EPA's RMP regulation * A summary of results from our assessment of the potential offsite consequences from accidental chemical releases * An overview of our accidental release prevention programs * A five-year accident history for accidental releases of chemicals regulated by EPA's RMP rule * An overview of our emergency respon se program * An overview of planned improvements at the facility to help prevent accidental chemical releases from occurring and adversely affecting our employees, the public, and the environment * The certifications that EPA's RMP rule requires us to provide * The detailed information (called data elements) about our risk management program STATIONARY SOURCE AND REGULATED SUBSTANCES Our facility stores butane and iso-butane from the Shell Refinery located across the street. The butane and iso-butane is stored in two 25000 BBL spheres. Receipts and deliveries are coordinated between the Shell Refinery personnel and BP Amoco-Wood River marketing personnel. In our processes, we use the following chemicals that EPA has identified as having the potential to cause significant offsite consequences in the event of a substantial accidental release: Toxics Not applicable Flammables Butane Iso-butane Our accidental release prevention programs and our contingency planning e fforts help us effectively manage the hazards that are posed to our employees, the public, and the environment by our use of these chemicals. KEY OFFSITE CONSEQUENCE ANALYSIS SCENARIOS EPA's RMP rule requires that we provide information about the worst-case release scenario(s) and alternative release scenario(s) for our facility. The following are brief summaries of these scenarios, including information about the key administrative controls and mitigation measures to limit the exposure distances for each scenario: Worst-case Release Scenario(s) - Regulated Toxic Chemicals Not applicable Alternative Release Scenario(s) - Regulated Toxic Chemicals Not applicable Worst-case Release Scenario(s) - Regulated Flammable Chemicals The BP Amoco Wood River facility has determined the worst case scenario to be a vapor cloud explosion of a 25,000 BBL aboveground butane sphere. This sphere contains a maximum of 892,500 gals. (85% of storage capacity) of butane or iso-butane. This scenario was based upon the remote possibility of the sphere being compromised due to physical or mechanical damage. The distance to 1 PSI overpressure has been calculated at 1.3 miles. Based upon 1990 census data, US Geological Survey maps and aerial photography, BP Amoco Wood River has determined the following public receptors are within the1.3 miles (8000 residents, 3015 homes, 5 schools, 3 post offices, 3 city halls, 3 parks, a public recreation area, and several commercial businesses). One environmental receptor was found, the Lewis and Clark Monument. To eliminate potential fuel sources, the following control measures are (1) the storage is diked and (2) a vegetation control program is in place. Alternative Release Scenario(s) - Regulated Flammable Chemicals BP-Amoco Wood River has reviewed several alternate release scenarios at the Wood River facility. The scenario selected for the RMP reporting was a 3-inch hole located at the bottom of the butane sphere. The s cenario could result from a physical or mechanical compromise of the sphere. Complete loss of contents was considered due to limited access to the sphere. The area is however surrounded by a dike 300 ft. by 170 ft. Product would accumulate to a depth of 2.8 ft. The area is also protected by a firewater system; however, no credit was taken for reduced flammable vapor levels. As much as 892,500 gallons (85% of storage capacity) of butane or iso-butane would be released and subject to a pool fire. The calculated distance to the lower explosive limit (LEL) is less than .06 miles and the endpoint radius of impact to 5 KW/m2 for forty seconds is .25 miles. Based on 1990 census data, US Geological Survey maps and aerial photography, BP Amoco Wood River has determined the following public receptors are within the .25 miles (3300 residents, 811 homes, several commercial businesses, two schools, and a public recreation area). No environmental receptors were found. Control measures for the butane storage area include (1) dike walls, (2) vegetation control program, and (3) personnel on site 24 hours a day. We are using this information to help us ensure that our emergency response plan and the community emergency response plan address all reasonable contingency cases. GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND CHEMICAL-SPECIFIC PREVENTION STEPS We take a systematic, proactive approach to preventing accidental releases of hazardous chemicals. Our management systems address each of the key features of successful prevention programs including: * Process safety information * Process hazard analysis * Operating procedures * Training * Mechanical integrity * Management of change * Pre-startup review * Compliance audits * Incident investigation * Employee participation * Hot work permit * Contractors As part of our prevention efforts, we have implemented the following chemical-specific prevention steps: . H.A.D. Systems. Heat activ ated detection - deluge. Hydrocarbon detection system. Safety Relief Valves. Dike walls surrounding each individual sphere. Remote operated twin seal valves on suction and fill lines & twin seal valves behind MOV's. Critical instrument list. Checklist for monthly, quarterly, semi-annual, annual inspections of critical instruments. These individual elements of our prevention program work together to prevent accidental chemical releases. Our company and our employees are committed to the standard that these management systems set for the way we do business, and we have specific accountabilities and controls to ensure that we are meeting our own high standards for accident prevention. Below is a copy of our employee participating statement, the key element to our Process Safety Management and Risk Management prevetion programs.
