D. Malmstedt\nAmerican Insurance Association\n85 John Street\nNew York, New York, 10038\nDear Mr. Malmstedt:\nPlease refer to you letter of May 6, 1971, Office of Pipeline Safety reply of June 14, 1971, and\nyour return letter of June 29, 1971, concerning the requirements of Paragraph 192.197(a)(1)\nthrough (6).\nIn your letter of June 29, 1971, you ask the specific question, \"Does the regulation allow the\ninstallation of gas pressure regulators without either an internal relief valve or internal safety\nshutoff with manual reset where the distribution system supply to the regulator is 60 psig or less?\"\nThe answer is yes, the regulations as they now stand permit the installation of service regulators\nwithout either an internal relief valve or internal safety shutoff with manual reset where the\ndistribution system supply to the regulator is 60 psig or less.\nIn drafting the original proposals for Part 192, we was pointed out in the preamble to that\ndocument, OPS used as its sources the best of the laws then in effect in the various states. There\nwere then no requirements for internal relief valves or automatic overpressure cutoffs on service\nregulators supplying customers from systems operating at 60 psig or less. In compiling data and\nanalyzing the leak and annual reports, this is one of many areas we are giving consideration to.\nHowever, thus far, there has been no indication for any reason for changing the requirement.\nWe hope this answers your question. If there are any further questions, please let us know.\nSincerely,\n/signed/\nJoseph C. Caldwell\nActing Director\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\197\\71-07-13\n1","truncated":false,"body_characters":1667}
