CERTIFICATION STATEMENT: TO THE BEST OF THE UNDERSIGNED'S KNOWLEDGE, INFORMATION, AND BELIEF, FORMED AFTER REASONABLE INQUIRY, THE INFORMATION SUBMITTED IS TRUE, ACCURATE, AND COMPLETE. ________________________________________ _______________________________________ Signature Date ___________GERALD N. CRAIG_____________ _______________PRESIDENT______________ ACCIDENTAL RELEASE PREVENTION & EMERGENCY RESPONSE POLICIES: This facility complies with NFPA-58 requirements for LP-Gas storage. Our policy is to adhere to all applicable federal, state, and local laws. If an emergency were to occur, our policy is to notify the Wichita Falls Fire Department (911) and request that they respond to the emergency. We have communicated with the Wichita County LEPC and informed them of the presence of a propane fuel storage tank farm onsite. Our plan t is included in the community response plan. FACILITY DESCRIPTION: This facility is a natural gas fired cogeneration plant. If the natural gas supply is interrupted, propane is used as an emergency backup fuel for three turbines located onsite. Use of propane as an emergency backup fuel has been required only once since plant startup in 1987. WORST CASE & ALTERNATIVE RELEASE SCENARIOS: Our worst-case scenario is failure of a 30,000 gallon storage tank when filled to the greatest amount allowed (88% at 60oF) resulting in a vapor cloud explosion. The resulting distance to the endpoint extends offsite. Public receptors are within the distance to the endpoint. Our alternative release scenario is a break in a 2.0 inch diameter pipe resulting in a ten minute release and explosion. The resulting distance to the endpoint extends offsite. Public receptors are within the distance to the endpoint. ACCIDENTAL RELEASE PREVENTION PROGRAM & CHEMICAL SPECIFIC PREVENTION STEPS: This fa cility complies with EPA's accident prevention rule and all applicable state and local codes and regulations. The propane system is designed, installed, and maintained in accordance with NFPA-58, Texas Railroad Commission requirements, and U.S. D.O.T. rules and regulations. FIVE YEAR ACCIDENT HISTORY: We have never had an accident involving propane that caused deaths, injuries, property or environmental damage, evacuations, or shelterings in place. EMERGENCY RESPONSE PROGRAM: In the event of an emergency involving our propane system, our policy is to notify the Wichita Falls Fire Department and request that they respond to the emergency. We have discussed this policy with the fire department. Members of the fire department have inspected our propane system. PLANNED CHANGES TO IMPROVE SAFETY: No changes were indicated following a review of our current practices. |
