L. Fegenbush\nDirector, Pipeline Safety\nRailroad Commission of Texas\nCapitol Station\nP. O. Box 12967\nAustin, Texas 78711-2967\nDear Mr. Febenbush:\nYour letter of July 13, 1984, supplying additional information concerning the waiver from\ncompliance with 49 CFR §192.199(g) granted April 30, 1984, by order of the Railroad\nCommission of Texas to Lone Star Gas Company has been reviewed along with your April 30,\n1984, letter forwarding the waiver.\nA detailed study was made of the design of the Fisher S-203 pressure regulator and the design of\nthe typical installations made by Lone Star Gas Company. In addition, a telephone conference\ncall was conducted with Fisher Controls Company representatives that involved staff members of\nboth the Office of Pipeline Safety Regulation and the Office of Operations and Enforcement of the\nMaterials Transportation Bureau. This call clarified certain design features of the Fisher S-203\npressure regulator.\nAfter consideration of these factors, I have determined the waiver granted by the Commission's\nApril 30th order may take effect provided that:\nm The waiver applies only to Fisher S-203 pressure regulators installed prior to April 30,\n1984, by Lone Star Gas Company.\nm A list specifically identifying each regulator station fitted with a Fisher S-203 pressure\nregulators to which the waiver applies is maintained by the Commission.\nm Each of these aboveground regulator stations has adequate safeguards against outside\nforce damage provided by site selection, barriers, or markers.\nm If any part of those stations to which the waiver applies is modified, replaced, or\nrelocated, the pressure relief or pressure limiting devices must comply with §192.199(g).\nSincerely,\nDB\nC:\\WP51\\INTERPRT\\192\\199\\84-10-02\n1\n\n<<<PAGE 2>>>\n\nRichard L.
