Hogan\nAssistant Vice President and Chief Engineer\nNorthern Illinois Gas\nP.O. Box 190\nAurora, IL 60507-0190\nDear Mr. Hogan:\nI am responding to your letter of February 1, 1993, regarding the pressure testing requirements of\nSubpart J or 49 CFR part 192. You asked us to confirm the following interpretation: \"A tie-in or\nreplacement section of bare steel pipe to be operated at less than 100 psig is exempt from the\npressure testing of this Subpart if it does not include a field made butt-weld other than the 'final\ntie-in joints'.\"\nWe have reviewed the pertinent part 192 standards but, unfortunately, cannot confirm your\ninterpretation. Steel pipe installed as a replacement to be operated at less than 100 psig is subject\nto the pressure testing requirements of Subpart J.\nSincerely,\nCesar De Leon\nDirector, Regulatory Programs\nOffice of Pipeline Safety\ndal\\192\\503\\93-04-22","truncated":false,"body_characters":920}
