Executive Summary

Executive Summary



Accidental release prevention and emergency response policies:

The Larose Cryogenic Plant has implemented all the elements of a Program 3 Risk Management Plan (RMP) and all the elements of OSHA's Process Safety Management (PSM) program. The plant has also implemented all the elements of Williams Midstream's System Integrity Plan (SIP), which contains additional environmental, health, and safety standards. The Larose Cryogenic Plant's Emergency Response Plan is site-specific. It includes required actions by plant employees as well as required notification and coordination with local responders and agencies. All employees are trained in the execution of the Emergency Response Plan and drills are conducted annually.



The Stationary Source and Regulated substances:

The Williams Field Services - Larose Facility is a natural gas processing plant that receives natural gas from pipelines and separates the gas stream via fractionation into pipeline quality natural gas (primarily methane) and natural gas liquids (NGLs) (ethane, propane, butanes, and natural gasoline). The Products from the facility are transferred via commercial pipeline. The regulated chemicals in the process are:

Methane

Ethane

Propane

i-Butane

Butane

i-Pentane

Pentane



General Accidental Release Prevention Program:

The Larose Cryogenic Plant has implemented all the elements of a Program 3 Risk Management Plan (RMP) and all the elements of OSHA's Process Safety Management (PSM) program. The plant has also implanted all the elements of Williams Midstream's System Integrity Plan (SIP), which contains additional environmental, health, and safety standards. Key elements of these programs include:

Employee Participation: Participation in the development of the Larose Gas Processing Plant's process safety and risk management compliance is outlined in the Employee Participation Plan. Employees and affected contractors have access to information developed as part of the facili
ty's PSM and accident prevention program.

Process Safety Information: A variety of technical documents that are used to help maintain safe operation of the process.

Process Hazard Analysis (PHA): A systematic examination of the plant to identify possible hazards and ensure that adequate controls are in place to manage these hazards.

Operating Procedures: Larose Cryogenic Plant maintains written procedures that address various modes of process operations, such as (1) initial start-up, (2) normal operations, (3) temporary operations, (4) emergency shutdown, (5) emergency operations, (6) normal shutdown, and (7) start-up after turnaround.

Contractors: Larose Cryogenic Plant uses contractors to supplement its workforce during periods of increased maintenance or construction activities. Because some contractors work on or near process equipment, the plant has procedures in place to ensure that contractors, (1) perform their work in a safe manner, (2) are aware of any hazards In the workplace, (3) understand what they should do in the event of an emergency, (4) understand and follow site safety rules, and (5) inform plant personnel of any hazards that they find during their work.

Pre-startup Safety Reviews (PSSRs): The Larose Cryogenic Plant uses PSSRs as a part of the construction process. The purpose of the PSSR is to ensure that safety features, procedures, personnel, and equipment are appropriately prepared for startup before placing modified equipment into service.

Mechanical Integrity: Larose Cryogenic Plant has well established practices and procedures to maintain pressure vessels, piping systems, relief and vent systems, controls, pumps and compressors, and emergency shutdown systems in safe operating condition.

Safe Work Practices and Procedures: Examples of safe work practices utilized by the Larose Cryogenic Plant include methods for controlling plant entry, presence and exit of support personnel, and lock out tag out procedures to ensure isolation of
energy sources for equipment undergoing maintenance, hot work procedures and permits for work with the potential for generating ignition sources in the presence of flammable or combustible material, and confined space entry permits and procedure to ensure that adequate precautions are in place before entry is allowed into a permit required confined space.

Training: The plant has implemented a comprehensive training program for all employees involved in operating a process. The program includes classroom, OJT, and computer-based training. Employees are tested to demonstrate competency.

Management of Change: The Larose Cryogenic Plant utilizes a Management of Change process. In this, changes are reviewed to ensure that adequate controls are in place to manage any new hazards and to verify that existing controls have not been compromised by the change.

Incident Investigation: The Larose Cryogenic Plant utilizes an Incident Investigation process. The goal of each investigation is to determine the facts concerning an incident or near miss and to develop corrective actions to prevent recurrence of the incident or a similar incident.

Compliance Audits: At the Larose Cryogenic Plant, audits are conducted on a regular basis to ensure that the facility is in compliance with applicable RMP / PSM I SIP

procedures and regulations.



Five Year Accident History:

No release of a regulated substance has occurred in the last 5 years.







Emergency Response Program Information:

The Larose Cryogenic Plant maintains a written emergency response program to protect employees, contractors, public and the environment from hazards associated with accidental releases of regulated substances. The program consists of procedures for responding to releases of regulated substances, including the possibility of associated fires or explosions. The procedures address all aspects of emergency response, including

evacuation plans, accounting for personnel after an evacuation, notificatio
n of local emergency response agencies and the public, if a release occurs. Employees receive training in these procedures annually to perform emergency response duties. The program is updated when necessary based on modifications made to the gas plant processes. Emergency response program changes are administered through the MOC process.

The overall emergency response program for Larose Cryogenic Plant is coordinated with Lafourche Parish Emergency Planning Committee (LEPC). This coordination includes attending periodic meetings of the committee, which includes local emergency response officials and industry representatives. Larose Cryogenic Plant has 24-hour communications capability with the Lafourche Parish LEPC. The Plant conducts periodic emergency drills that involve the LEPC and emergency response organizations.
