Box 77\nChickasha, OK 73018\nDear Mr. Hartman:\nYour letter of March 22, 1974, to the National Transportation Safety Board, asking several questions about the Federal\ngas pipeline safety standards, has been referred to this office for reply.\nThe standards are contained in Part 192 of Title 49 of the Code of Federal Regulations (copy enclosed). We have no\nrequirements which specify the location of a pipeline right-of-way, since the Natural Gas Pipeline Safety Act of 1968\nexpressly precludes such requirements. However, many of the safety measures prescribed by the standards vary in\nnature according to pipeline locations.\nRequirements concerning the depth of cover over buried pipelines, applicable to pipelines readied for service after\nMarch 12, 1971, or replaced or relocated after November 12, 1970, are set forth in Subparts G and H of the standards.\nThe requirements vary according to whether the pipeline is a transmission line, main, or service line and certain other\nfactors of construction. Although cover material is normally compacted during construction, the Federal standards do\nnot require compaction.\nMany of the standards concern leaks. Under Subpart J, pipelines readied for service after March 12, 1971, and pipelines\nreplaced or relocated after November 12, 1970, must be pressure tested after installation. Leakage surveys are required\nby section 192.723. In general, the Federal standards do not prohibit leaks, but hazardous leaks must be repaired\npromptly and many leaks could lead to a pipeline having to be replaced, repaired, or removed from service (section\n192.703).\nWe trust this information is helpful to you.\nSincerely,\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\n\n<<<PAGE 2>>>\n\nMarch 22, 1974\nFarm Service Company\nP.O.

C. 20591\nDear Sir:\nPlease send me safety requirements for natural gas pipe lines. I am primarily concerned with natural\ngas pipe lines in rural and urban areas. What are the requirements for distance between improvements such\nas homes, commercial establishments and warehouses and the pipe line right of way? Also, what are the\nrequirements for depth of the pipe line and are there any requirements for tamping the material that covers\nthe pipe line? I am interested in pipe lines that vary from 6 inches to 30 inches in diameter and used to\ntransport natural gas. Are there any requirements concerning leaks?\nThanks for any information you can give me.\nSincerely,\nMonroe Hartman","truncated":false,"body_characters":2713}
