Baldacci, Jr.\nVice President\nThe Peoples Gas Light & Coke Co.\n122 South Michigan Avenue\nChicago, IL 60603\nDear Mr. Baldacci:\nThis refers to your letter of April 22, 1981, in which you request a determination that a particular pipeline that\nnow transports naphtha from the Union 76 refinery to an SNG plant may be used to transport alternately\nnaphtha and refinery gas.\nThe applicable Federal regulations governing the transportation of naphtha by pipeline in interstate\ncommerce are set forth in 49 CFR Part 195. Regulations governing the pipeline transportation of gas in or\naffecting interstate commerce are in 49 CFR Part 192. These regulations do not preclude a pipeline from\nbeing used in the manner your have proposed, provided the applicable requirements of each set of\nregulations are met.\nIn this regard, the pipeline need not meet each design and construction requirements of Part 192, that would\notherwise apply to a pipeline newly readied for gas service, if it is qualified for use under the conversion rules\nof §192.14. Note that this section would require that the pipeline be pressure tested under Subpart J, even\nthough it has been tested previously under Part 195. The MAOP for gas service would be determined under\n§192.619 based on the new pressure test.\nThe regulations do not require notification of the proposed changeover.\nSincerely,\nSIGNED\nMelvin A. Judah\nActing Associate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau","truncated":false,"body_characters":1521}
