HPL Resources Company Three Rivers Gas Plant - Executive Summary |
|
Accidental Release Prevention and Emergency Response This facility complies with industry standards for hydrocarbon gas processing. Our policy is to adhere to all applicable federal, state, and local laws. If an emergency were to occur, we would notify the George West Fire Department and request that they respond to the emergency. Facility Description and Regulated Substances Handled The Three Rivers Gas Plant is located in Live Oak County off of Airport Road near George West, Texas. The plant produces stabilized condensate, de-methanized/de-ethanized natural gas liquids (NGL), and residue gas. The NGL and residue gas are transported off-site vma pipeline. No NGL product tanks exist at the Three Rivers Gas Plant. Produced stabilized condensate is stored in one of two fixed roof atmospheric storage tanks. The liquids are stored onsite until loaded onto tank trucks and transported offsite. The Three Rivers Gas Plant does not handle any regulated toxic substances. Worst-case Re lease Scenario The main potential hazards at the Three Rivers Gas Plant are those from fires and explosions. These hazards are associated with any facility that handles large volumes of flammable hydrocarbons. The worst-case release scenario is defined as a release of the largest quantity of a regulated substance from a vessel or process piping failure that results in the greatest distance to an endpoint. The worst-case release scenario assumes that none of the many safety systems and process controls are operational. The distance for the worst-case release scenario presented in the RMP has been calculated using the method described in EPA's Off-site Consequence Analysis Guidance. The worst-case flammable release scenario is from the Product Surge Tank V-1103. The Product Surge Tank handles flammable mixture of light hydrocarbons, principally ethane, butane, and pentane. The worst-case release scenario is an aboveground vessel or piping failure. Approximately, 40,574 pounds of flammable material are released. The distance to the 1-psi endpoint is less than 0.28 miles. This release scenario does have an off-site impact; however, no public receptors are impacted. General Accidental Release Prevention Program This facility complies with EPA's accident prevention rule and all applicable state and local codes and regulations. Five-Year Accident History As a result of the facility's commitment to safety, no accidents as defined by the RMP rule, have occurred in the last five years. Emergency Response Program To be prepared for potential accidents, facility personnel communicate and work closely with local community responders. The Three Rivers Gas Plant maintains a written emergency response plan. This plan consolidated the multiple emergency response and contingency plans required by various federal and state regulations. This consolidation ensures rapid and appropriate response to quickly control any incident, and to minimize the consequences of any rele ase. The emergency response plan addresses pre-emergency planning and establishes personnel lines of authority, training, and communications. The emergency response plan also documents the procedures for informing the public and local responders about accidental releases and the procedures for review and updates of the plan. The provisions of the emergency response plan will be carried out immediately if a fire, explosion, or any unplanned or sudden release of a hazardous substance to air, soil, or surface water occurs at the Three Rivers Gas Plant. The local fire department (George West) has copies of this plan. These responders and facility personnel perform regular drills. Emergency response training is conducted for all employees.
