B. Haug\nEngineering/Design Development\nPanhandle Eastern Pipe Line Company\nP. O. Box 1348\nKansas City, Missouri 64141\nDear Mr. Haug:\nYour letter of July 21, 1983, asks if there is a legal maximum hydrogen sulfide content of\na natural gas stream to be transported both inter and intrastate, and if gas distribution\nsystems are treated the same.\nThe only legal limitation that we are aware of on the amount of hydrogen sulfide\npermitted in gas is the 0.1 grain of hydrogen sulfide per 100 standard cubic feet\nrequirement of Section 192.475(c). This limitation is only applicable to gas stored in\npipe-type or bottle-type holders.\nUnder the Natural Gas Policy Act of 1978, Section 110 and in the Federal Energy\nRegulatory Commission (FERC) Order 24, July 25, 1900, RM 88-47, 18 CFR Part\n271.1104, a limit of one grain per 100 cubic feet has been established as a dividing line\nbetween what may be charged against producer costs versus pipeline operator costs.\nHowever, this does not place any limit on the amount of hydrogen sulfide that may be\ntransported by pipeline.\nThere is no regulatory distinction in the Federal pipeline safety standards for gas\ndistribution systems relative to hydrogen sulfide content. Individual States may have\nadditional requirements for intrastate systems as long as they are not incompatible with\nthe Federal minimum standards.\nWe hope that this provides the information you need.\nSincerely,\nRichard L. Beam\nAssociate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau\n\n<<<PAGE 2>>>\n\nJuly 21, 1983\nDepartment of Transportation\nOffice of Pipeline Safety\n400 7th St.\nS.W., Washington, D.C. 20270\nDear Sirs:\nI am writing you in order to determine if there is a legal maximum hydrogen sulphide\ncontent of a natural gas stream to be transported both inter and intra state. Also, are gas\ndistribution systems treated the same?\nIf you can refer me to proper legislation or guides, please write me at the address below.\nI currently am aware of NACE MR-01-75 (1978) and DOT paragraph 192.475.\nThank you, in advance, for your cooperation.\nSincerely, yours,\nJ.
