Metson Station - Executive Summary

| Accident History | Chemicals | Emergency Response | Registration | Source | Executive Summary |

EOTT Energy Operating Limited Partnership (EOTT Energy) acquired the Metson Station on December 1, 1998.  The Metson Station is a Liquefied Petroleum Gasoline (LPG) / crude oil blending and transfer facility.  The process is regulated by Cal OSHA Process Safety Management of Acutely Hazardous Materials, Title 8 California Code of Regulations 5189.  The facility is currently implementing the prevention program described below. 
EOTT Energy has a commitment to employee and public safety. This commitment is demonstrated by the resources invested in accident prevention, such as training personnel and considering safety in design, installation, operation, and maintenance of covered processes.  EOTT Energy's policy is to implement reasonable controls to prevent foreseeable releases.  However, if a release does occur, trained personnel will respond to control and contain the release.   
The prevention program is designed based on 40 CFR Part 68 and Title 19 CCR 2735.  The program includes the 
following areas:  Employee Participation, Process Safety Information, Process Hazard Analysis, Operating Procedures, Training, Contractor Evaluation, Contractors and Visitor Orientation, Pre-Job Start-Up Review, Mechanical Integrity, Code of Safe Work Practices (Hot Work Permit, Confined Space Entry, Control of Hazardous Energy), Management of Change, Incident Investigation, Emergency Planning and Response, and Compliance Audits.  Planned changes to improve safety have been established based on compliance with the process safety management audits and revalidation of the process hazard analysis.  Training includes employee responsibilities in the process safety management program, emergency response, hotwork permit procedure, code of safe work practices, and operating procedures. 
The facility stores and unloads natural gasoline.  There are 2 tanks with a capacity of 75,600 gallons.  The tanks are administratively controlled to hold liquefied petroleum gasoline at 90% maximum capacity; 
therefore,  the worst case flammable scenario is based on a 68,040 gallon release. 
EOTT Energy maintains an emergency response plan in compliance with local emergency response agencies.  The Metson Station has a Hazardous Materials Business Plan on file with the Kern County Environmental Health Department - Certified Unified Program Agency. 
In the event of an accidental release, the facility operators are trained to sound the alarm, shut off the source from a safe location or activate one of the emergency shutdown devices, contact 9-1-1 and secure the area.  The 9-1-1 system is used to notify the Fire Department. 
Based on the criteria set forth 40 CFR 68.10 and 19 CCR 2735.4, this facility has not had an accidental release.  This information was verified by the reviewing of records from the Kern County Environmental Health Department - Certified Unified Program Agency. 
The worst case release scenario is based on the Environmental Protection Agency Offsite Consequence Analysis Guid 
ance equations and model.  The worst case scenario and alternate release scenario were based on n-butane as the modeled substance.  The facility stores and transfers primarily natural gasoline, of which n-butane is a component.  The worst case release of 340,500 lbs of liquefied petroleum gasoline indicates a 1 psi overpressure distance of 0.56 miles. This distance impacts public receptors of an adjacent wildlife conservancy and a crude oil production facility.  Although there are numerous controls in place, no credit was taken into account for evaluating the worst case scenario.  The Alternative Release Scenario for this process is a break in transfer hose connection.  This scenario could result in release of 60 lbs of liquids over a 10 minute period. The maximum distance for this scenario is 0.03 miles.  The process maintains mitigation measures such as relief valves, check valves, manual shutoff valves, automatic shutoffs, startup and operating procedures, grounding equipment, and e 
xcess flow devices.  The facility operator and truck driver are in attendance during transfer operations. 
The engineering and administrative controls in place have been established to reduce the risk of an accidental release of identified hazards.  EOTT Energy is committed to operations which are safe for employees and the surrounding community.
