Garabrant, P.E.\nGas Utilities Safety Engineer\nUtilities Division\nArizona Corporation Commission\n2222 West Encanto Boulevard\nPhoenix, Arizona 85009\nDear Mr. Garabrant:\nThis responds to your letter of October 20, 1978, regarding the applicability of sections\n192.619(b) and 192.621(b).\nYour letter notes that sections 192.619(b) and 192.621(b) are operation requirements which are\nnot \"grandfathered\" and are continuing regulations that are applicable to all pipelines. Your letter\nmentions that both of these sections reference section 192.195 which sates, in part, that \"...must\nhave pressure relieving or pressure limiting devices that meet the requirements of sections\n192.199 and 192.201.\" As you noted, sections 192.195, 192.199, and 192.201 are design\nrequirements which only apply to pipelines readied for service after March 12, 1971, or replaced,\nrelocated, or otherwise changed after November 12, 1970. You inquire if you are correct in\ninterpreting that all district regulators including those readied for service before March 21, 1971,\nmust meet the requirements of section 192.621(b).\nBecause section 192.195 is incorporated by reference in sections 192.619(b) and 192.621(b),\nwhich are operating requirements, the provisions of section 192.195 apply to those pipelines\nreadied for service before March 21, 1971, if section 192.619(b) or section 192.621(b) applies to\nthe pipelines concerned.\nWe trust that this adequately responds to your inquiry.\nSincerely,\nCesar DeLeon\nAssociate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau\ndal\\192\\619\\79-02-14","truncated":false,"body_characters":1624}
