I. Snyder\nExecutive Vice President\nSouthern California Gas Company\nBox 3249 Terminal Annex\nLos Angeles, California 90051\nDear Mr. Snyder:\nThis responds to your letter of May 15, 1975, asking us to reconsider an interpretation published\nin the July 1974 issue of the Advisory Bulletin. That interpretation provides that in uprating steel\npipelines operated at 100 psi or more with hoop stresses less than 30 percent SMYS to a pressure\npermitted by Section 192.619(a)(2)(ii), a pressure test must be performed.\nWe have reviewed the arguments presented in your letter and feel that the interpretation is\ncorrect. We would like to point out however that the pressure test required in uprating to a\nmaximum allowable operating pressure permitted by Section 192.619(a)(2)(ii) need not be a\nhydrostatic test. The test may be conducted with the gas being transported.\nWe appreciate your interest in pipeline safety.\nSincerely,\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\ndal\\192\\619\\75-06-24\n1","truncated":false,"body_characters":1030}
