Executive Summary

Environmental Protection Agency Risk Management Plan
Enterprise State Line Compressor Station
RMP Executive Summary

At Enterprise's State Line Compressor Station, we are committed to operating and maintaining all of our processes (especially those handling hazardous substances) in a safe and responsible manner. We use a combination of accidental release prevention programs and emergency response planning programs to help provide for the safety of our employees and the public, as well as protection of the environment.

The State Line Compressor Station is owned and operated by Enterprise Products Operating LLC.

This document provides a brief overview of the comprehensive risk management activities that have been designed and implemented, including:

* A description of our facility and use of substances required by EPA's RMP regulation and the processes involved.
* A summary of results from our assessment of the potential offsite consequences from accidental chemical releases.
* Emergency Response Programs.
* General Accidental Release Prevention Program and Chemical-Specific Prevention Steps.
* A five-year accident history for accidental releases of chemicals at the State Line Compressor Station that are regulated by EPA's RMP rule.

Facility Description

The State Line Compressor Station is a field gas compression and dehydration facility. A gas cooling unit utilizes chilled, circulating water to help cool the facility inlet gas to remove condensed natural gas liquids (NGL) from the inlet gas. The condensed NGL is sent to an NGL storage bullet and is removed from the facility via tanker truck. The residue gas stream is compressed and shipped via pipeline to distribution by others.

In our process we use the following chemicals/flammables that the EPA has identified as having the potential to cause significant offsite consequence in the event of a substantial accidental release:

Toxics

No toxic materials to report.

Flammables

A mixed natural Gas Liqu
id (NGL) is the only flammable substances that is maintained in a quantity above the threshold quantities listed in 40 CFR 68.115.

Key Offsite Consequence Analysis Scenarios

The EPA's RMP rule requires that we provide information about the worst-case scenarios(s) and alternative release scenario(s) for our facility.

Worst/Alternate Case Release Scenarios - Regulated Toxic Chemical

At the present time there are no regulated toxic chemicals to report for the State Line Compressor Station.

Worse/Alternate Case Scenarios - Regulated Flammable Chemicals

The worst case scenario for the State Line Compressor Station involves the amount of flammable NGL mixture that would be released if the NGL storage tank suffers a catastrophic failure and release. The details of the offsite consequence analysis will not be reflected in the executive summary but rather are reflected in the data components of the RMP. There are no receptors in the Worst Case Scenario distance, so the facility is eligible and is being registered as an RMP Program 1 facility.

Emergency Response Program

Enterprise's State Line Compressor Station maintains an Emergency Response Plan (ERP) in compliance with local emergency response agencies. The location is visited daily by operations personnel who receive extensive Environmental, Health and Safety training. High pressure and high level alarms are in place with automatic shutdown controls to react to abnormal operating conditions. The system volumes and pressures are monitored through a supervisory control and data acquisition system (SCADA).

The ERP is reviewed with Enterprise's employees at least annually or when any changes are made to the ERP.

General Accidental Release Prevention Program and Chemical-Specific Prevention Steps

As a part of the prevention efforts, there are several programs in which Enterprise employees participate. A training program has been developed in which Operations and Maintenance personnel are specifically tra
ined in the operation of the facility, the operating procedures, maintenance procedures, and specific other regulations and policies, as well as in all areas of emergency response. All of these programs come under scheduled scrutiny and critique.

Operations personnel make regular inspections of the equipment and processes they operate. If something out of the ordinary is found, it is reported to management in order to expediently resolve any problems.

The engineering and administrative controls in place have been established to reduce the risk of an accidental release of identified hazardous materials. Enterprise is committed to operations that are safe for employees and the surrounding community.

Accident History

Based on the criteria set forth in 40 CFR 68.10, this facility has not had any accidental release in the past 5 years.

Planned Changes to Improve Safety

The following is a list of improvements that have either been recently completed or are planned for implementation at the facility to help prevent and/or better respond to accidental chemical releases:

* Enterprise has just recently acquired ownership and operation of the State Line Compressor Station. The Company is currently working to provide communication of operating information into the Company's centralized control facility to provide 24-hour monitoring of key operating variables.
