E. Mickelson\nChief Engineer-Gas Operations\nCentral Telephone & Utilities Corp\nP. O. Box 82888\nLincoln, Nebraska 68501\nDear Mr. Mickelson:\nThis is in reply to your request for an interpretation of 49 CFR, Section 192.511 and Section\n192.513.\nYou are correct that Section 192.511 does not apply to plastic lines.\nSection 192.3 was intended to use the word \"pipeline\" in its broadest sense, that is all parts of\nthose physical facilities through which gas moves in transportation. It therefore includes service\nlines.\nTherefore, it is the intention of the regulations that Section 192.513 apply to all plastic lines,\nwhether they be transmission, mains or service lines.\nThe requirements for testing plastic are higher particularly for intended higher operating pressures\nthan those for steel because the design specifications for plastic are much less detailed.\nWe hope that this answers your question. If you have any further questions, please let us know.\nSincerely,\n/signed/\nJoseph C. Caldwell\nDirector, Acting\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\512\\71-02-19\n1","truncated":false,"body_characters":1097}
