D. Hodges\nPan American Engineers\n2708 N. Acadian Thru. W.\nBaton Rouge, Louisiana 70805\nDear Mr. Hodges:\nThis is in response to your letter of September 27, 1972, addressed to Mr. Taylor of our Houston\noffice. With regard to natural gas system, you ask whether testing (in the form of leakage\nsurveys) is required by the regulations for service lines going from the mains to the gas meter.\nSection 192.723 of Part 192, Transportation of Natural and Other Gas by Pipeline: Minimum\nFederal Safety Standards, (49 CFR Section 192.723), requires that each operator of a distribution\nsystem shall provide for periodic leakage surveys. Since distribution lines are integral parts of a\ndistribution system, such lines would be subject to the leak survey requirements of Section\n192.723. Section 192.3, in turn, defines service line as a distribution line that transports gas from\na common source of supply to a customer meter set assembly. Therefore, service lines from\nmains to the gas meters are required to be included in the periodic leakage surveys in accordance\nwith the provisions of Section 192.723.\nI trust this provides the clarification you need. If you have further questions, we will be pleased\nto respond.\nSincerely,\n/signed/\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\nDB/dal/192.723\n72-10-17","truncated":false,"body_characters":1346}
