PIPELINE MARKERS For public-safety reasons, most pipelines are buried several feet underground. To make pipelines easier to locate and identify, CPWA installs markers near roads and highways, at railroad and river crossings, above ground piping and at other locations along our rights of way. These markers show a pipeline's approximate location and provide emergency-contact telephone numbers and product transported. Not all buried lines have markers. Therefore, prior to performing excavating activities as simple as planting a tree, installation of landscaping, building a fence, installing a swimming pool or installation of a mailbox, contact OKIE One-Call at 811 or 1-800-522-6543. PHMSA guidelines require CPWA to make you aware of certain recommendations regarding your underground natural gas piping. CPWA does not maintain the gas piping past the customer’s meter. Piping beyond the meter is the responsibility of the consumer. Buried customer piping may be subject to corrosion and/or leakage. Your buried piping should be checked periodically to ensure safe operation. You are advised to contact a licensed plumber or contractor to assist you in locating and inspecting your buried gas piping. Should an unsafe condition occur, repairs should be made immediately. HIGH CONSEQUENCE AREAS In accordance with federal regulations some areas near pipelines have been designated as High Consequence Areas. For these areas Integrity Management Programs are in place to inspect these pipelines periodically for corrosion and other anomalies. For further information contact CPWA at 918.476.8925. PIPELINE SAFETY IS BUILT IN PHMSA (Pipeline & Hazardous Material Safety Administration) imposes rigorous standards for pipeline design, construction, maintenance, testing and operation. CPWA policies and procedures are designed to meet and, in most cases, exceed these standards. Our commitment to safety begins before a pipeline is built or expanded. We build safety into our system by: carefully researching and planning the safe construction of each project; using pipe that is inspected and tested at the factory to comply with both federal and industry standards; providing steel pipe with a coating and other measures that protect it from external corrosion, the use corrosive resistant polyethylene plastic; inspecting the integrity of the pipe during construction; testing the finished pipeline at pressures higher than normal operating pressure before it's placed into service. SAFETY IS MAINTAINED DURING OPERATION Once a pipeline is built. tested and placed in service, CPWA controls and monitors the safety of its system in several ways, including: routinely patrolling our pipeline route on the ground to inspect for leakage and identify potential problems and assist in preventing third-party excavation damage. Other maintenance of facilities including: over-pressure protection devices inspections; cathodic protection inspection (a means of adding negative DC current to steel pipelines to slow corrosion); advising periodically, state and local emergency officials to review accident-prevention and emergency-response procedures; posting markers with emergency telephone numbers along our rights of way, at highway, railroad crossings to inform the public of a buried pipeline in the area or an above ground piping Public Awareness& Damage Prevention Chouteau Public Works 24-hour Emergency Number 918.373.3644 NATURAL GAS LEAKS: RECOGNITION AND RESPONSE Natural gas pipeline leaks or failures are rare, but an informed public can help prevent emergencies and minimize potential damage or injury in the unlikely event of an accident by knowing how to recognize and report pipeline problems. HOW TO IDENTIFY A LEAK The following signs may indicate a natural gas pipeline leak or failure: SIGHT A dense fog, mist, or white cloud, bubbling in water and creeks, or blowing dust and discolored or dying vegetation. SMELL Natural Gas is odorless, so a rotten egg odor is added to aid in leak detection. SOUND Whistling, hissing, or roaring noise.
