Boes\nManager of Gas Systems\nStandards & Procedures\nIndiana Gas Company\n1630 North Meridian Street\nIndianapolis, IN 46202-1496\nDear Mr. Boes:\nThis responds to your letter of April 17, 1992, to Mr. Richard Sanders of the Transportation\nSafety Institute in which you ask if the 3/8\" external line on the Sprague CL34-2 IMR regulator is\na \"static or control line\" as set forth in Section 192.197.\nThe \"static or control line\" in Section 192.197(a)(6) is a line that runs from the regulator to the\ndownstream side of the regulator used to communicate that pressure to the regulator. The 3/8\"\nexternal tubing on the Sprague CL34-2 IMR is not a static or control line, but a supply line\nsupplying high pressure gas from the inlet side of the regulator to the pilot to establish the set\npoint; i.e., the outlet pressure of the regulator.\nI trust that this has adequately responded to your question.\nSincerely,\nCesar De Leon\nDirector\nRegulatory Programs\nOffice of Pipeline Safety\njt\n192.197/92-06-29","truncated":false,"body_characters":1032}
