Logan\nProfessional Engineer\nP.O. Box 456\nMatches, MS 39120\nDear Mr. Logan:\nThis responds to your letter of October 10, 1974, advising that a paved road will be constructed 110 feet above a buried\ngas transmission line without disturbing the line. You ask what effect the construction will have on the pipeline\nrespecting requirements for (1) encasement, (2) class location, and (3) operating pressure in 49 CFR Part 192.\nBecause the existing pipeline will not be replaced, relocated or otherwise changed due to construction of the road, the\nFederal gas pipeline safety standards concerning encasement would not apply. The class location of the pipeline as\ndetermined by 49 CFR 192.5 would not be changed as a result of the construction. Because operating pressure is related\nto class location under the Federal standards, there would be no change in allowable operating pressure.\nWe trust this satisfactorily responds to your inquiry.\nSincerely,\nOriginal signed by:\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\n\n<<<PAGE 2>>>\n\nRichard T.

C. 20590\nRE: Texas Eastern Transmission Pipe Line Crossing\nSAP 79 (20), Wilkinson County, Mississippi\nPlease find enclosed a set of plans on State Aid Project Number\nSAP 79 (20), showing Texas Eastern Transmission's pipe line crossing.\nPlease note, on page 4 at approximate Station 59 + 52, that the pipe line is presently 6 feet in the ground. We propose\nto build a road over said ground and will be 4 feet above the present route, leaving a total fill depth of 10 feet. This will\nbe a paved rural county road, which qualifies in the State Aid program. The traffic count is only 100 ADT. We are not\ngoing to move, relocate or disturb the present pipe line.\nUnder these conditions as stated above, will the present pipe line need: (1) encasement, or (2) change class location, or\n(3) change operating pressure.\nPlease advise me at your earliest convenience, in order that we may proceed with this project.\nVery truly yours,\nRichard T. Logan, County Engineer\nWilkinson County, Mississippi","truncated":false,"body_characters":2252}
