Cobb\nCollins & Ryan, Inc.\nDupont Boulevard\nMillesboro, Delaware 19966\nDear Mr. Cobb:\nThis refers to your correspondence with this office dated November 1, 1971, requesting information concerning\n49 CFR part 192 – Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards.\nThe sections referred to when answering each question should not be interpreted to imply that they are the\nonly sections governing the question.\nQuestion No. 1: As an L.P. gas supplier how many customers are we allowed to hookup on one\nunderground or aboveground gas tank?\nOur regulations do not limit the number of customers that may be served from on tank. However, Section\n192.11 requires that if you have ten or more customers you shall meet the standards under part 192 and of\nNFPA stands Nos. 58 and 59. In the event of a conflict, the requirements of this par prevail.\nQuestion No. 2: How many inches below ground should underground lines be placed, the lines being ¾”\nto 1 ½” in diameter?\nSection 192.327 prescribes the minimum cover for transmission lines and mains and Section 192.361 prescribes\nthe minimum cover for service lines. You may also wish to refer to Section 192.3 for the definition of\ntransmission line, main and service line.\nQuestion No. 3: May we, if necessary, run gas lines under a road in a park that the road is maintained\nsolely by the park owner and not by the state or town?\nThe geographic location of pipelines is not specified by our regulations. The location is by agreement between\nthe operator and the property owner. Our regulations do specify certain requirements of facilities in specific\nlocations. The road as described in your letter would not be considered as a public place as referenced in\n192.11(a). However, if your system has ten or more customers then it would come under our regulations and\nappropriate regulations would apply to all the facilities including those in the road.\nQuestion No. 4: What type (Galv. Or Copper) lines are recommended to be used underground?\nThe Department does not make recommendations as to what type of material to use, but after the selection of\nthe material by operator the regulations do specify certain requirements for specific materials.\nQuestion No.5: Is there any regulation as to how often and underground system has to be checked for\nleaks?\nSection 192.705 prescribes the patrol program for transmission pipelines affecting safety and operation.\nSection 192.721 prescribes the frequency of patrolling mains for consequent hazards to public safety. Section\n192.723 prescribes for periodic leakage surveys in its operation and maintenance plan.\nQuestion No. 6: For example: a system has 9 customers on it. It is required that each customer must have\na cut off valve other than the central one on the tank?\nThis question is similar to question No.1. If you have ten or more customers the applicable requirements of part\n192 apply to the facilities. Section 192.179, 192.181, 192.363, and 192.365 prescribe requirements for valves.\nSincerely,\nOriginal signed by:\nJoseph C. Caldwell\nActing Director\nOffice of Pipeline Safety\n\n<<<PAGE 2>>>\n\nCollins & Ryan, Inc.\nDupont Blvd.\nNovember 1, 1971\nMr. Joseph C.
