Waldrop\nUtilities Engineer\nAlabama Public Service Commission\nP. O. Box 991\nMontgomery, Alabama 36102\nDear Mr. Waldrop:\nThis is in reply to the two questions asked in your letter of June 1, 1973.\nQuestion: M.A.O.P.?\"\n\"...under 192.619 and 192.621. If a gas system is an all steel system and designed\nand tested for a 100 lb. system and has only operated at 30 lbs. for the last ten years, what is his\nAnswer: This system is governed by §192.619(c) which, in effect, allows the pipeline to\noperate at the highest actual operating pressure to which it was subjected during the 5 years\npreceding July 1, 1970. In the given case, the system operated only at 30 lbs. in that 5-year\nperiod. The M.A.O.P. is, therefore, 30 lbs.\nQuestion: regulations?\"\n\"...where a school is master metered and distributes the gas through its own piping\nto different buildings and they are ultimate consumers, would they be under gas pipeline safety\nAnswer: One of the characteristics of a master meter system that makes it subject to the\nregulations is a transfer of the gas from the operator to other persons who are the ultimate\nconsumers of the gas. In the situation described, however, the school taking delivery on gas\nthrough the \"master\" meter is not reselling or distributing any of the gas to any other person.\nWhere the gas is being used entirely by school employees for school purposes on school property,\nthe gas system is not subject to the federal gas pipeline safety regulations.\nIf you have further questions in this regard, please contact us.\nSincerely,\n/signed/\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\619\\73-06-19\n1","truncated":false,"body_characters":1674}
