Thompson\nThe University of Tennessee\nKnoxville, Tennessee 37916\nDear Professor Thompson:\nWe regret the delay in replying to your letter of January 16, 1978, concerning the East Tennessee\nNatural Gas Company's (ETNY) method of marking their pipelines.\nThe Federal regulation governing marking of gas pipelines is found in Title 49 of the Code of\nFederal Regulations, Part 192, Section 192.707 (copy enclosed). This regulation requires that\nmarkers installed other than at waterway crossings be written legibly on a background of sharply\ncontrasting color and that the lettering be at least one inch high. The particular type or size of\nmarker is not specified but is left to the gas operator's discretion provided the objective of the rule\n- to warn others of the presence of an underground pipeline - is carried out.\nIt does not appear from your letter that the markers you are concerned about conflict with the\nFederal requirements governing marking of pipelines. Therefore, it would be a matter for local\ncontrol or for negotiation between you and ETNY regarding the unsightliness of its markers in\nyour neighborhood and on your property.\nSincerely,\nCesar De Leon\nAssociate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau\nEnclosure\nDB\nC:\\WP51\\INTERPRT\\192\\707\\78-07-06\n1\n\n<<<PAGE 2>>>\n\nDepartment Head\nOffice of Pipeline Safety\nDepartment of Transportation\nWashington, DC 20002\nDear Department Head:\nThe East Tennessee Natural Gas Company, on 8200 Kingston Pike, Knoxville, TN 37919, has\nrecently altered their method of marking their pipelines. Formerly their two main lines in\nKnoxville were marked by a single, red, rectangular cement stake measuring about 12 to 15\ninches in height. These two parallel lines are separated by about 15 feet. The red stake has\nrecently been replaced by two, unsightly round markers measuring 12 inches in diameter.\nNeedless to say, these two signs, extending 12 inches from the ground, are real eyesores in our\nneighborhood and on my property.\nMy questions are these: (1) What is the minimal regulation governing such markers or signs? (2)\nIf the E.T.N.Y. Company markers are out of order, how can I remedy this situation? (3) Will\nyou help me persuade E.T.N.Y. to change these markers?\nThank you for your times and effort given to my concern.\nSincerely yours,\nCharles L. Thompson\nProfessor\nP.S. Complaint was made to Mr. Bob Davis of E.T.N.Y. who referred department.\nme to your\nDB\nC:\\WP51\\INTERPRT\\192\\707\\78-07-06\n2","truncated":false,"body_characters":2514}
