Ives\n3632 E. Five Point Highway\nCharlotte, Michigan 48813\nDear Mr. Ives:\nThis responds to your letter of May 6, 1976, concerning \"set back\" rules for gas pipelines in the\nproximity of occupied housing.\nUnder the Natural Gas Pipeline Safety Act of 1968, the Michigan Public Service Commission\nhas adopted and enforces the Federal gas pipeline safety standards (49 CFR Part 192) against\nintrastate gas pipeline within the Commission's jurisdiction. The Federal standards do not\ncontain \"set back\" rules, but do, however, provide for adequate safety through other types of\nrequirements which increase in stringency depending on the proximity of a pipeline to occupied\nareas. At the same time, the Michigan Commission may impose additional or more stringent\nsafety requirements.\nSincerely,\nCesar DeLeon\nActing Director\nOffice of Pipeline\nSafety Operations\n\n<<<PAGE 2>>>\n\nMay 6, 1976\nMr. A. Furow, Chief\nRegulation Division\nOffice of Pipeline Safety\nMaterial Transportation Bureau\nDepartment of Transportation\n2100 Second Street\nWashington D.C. 20590\nDear Mr. Furow:\nThe attached private gas transmission line is being presently constructed in the county road right-\nof-way through a rural area. As far as I can determine there are no set back rules in terms of\nexisting structures. The pipeline will have an anticipated operating pressure of 400 pounds and\nfalls about 20 feet from my basement. It appears to fall even closer to other houses along the\nright-of-way. To the best of my knowledge they have complied with Michigan's safety code.\nHowever, it is my feeling that in the proximity of occupied housing a conduit should be installed\nand vented. Otherwise there should be some set back rules particularly in heavy clay areas.\nDoes the Federal Government have any set back rules on constructions of this kind or are such\nmatters left up to the state authorities?\nSincerely,\nRobert E. Ives\n3632 E. Five Point Hwy.\nCharlotte, Michigan 48813\nEnclosure","truncated":false,"body_characters":2001}
