The answer to question number 2\nregarding pipeline river crossings was incorrect. I said that a design factor of 0.50, or less, is\nrequired for steel pipe in Class 1 or 2 locations in inland navigable waters, such as rivers. This\nanswer was based on an incorrect reading of §192.111(d)(2).\nThe design factor for steel pipe, including pipe in inland navigable waters, such as rivers, is\ngoverned by §192.111(a), except as provided in §192.111(b)-(d). Under §192.111(a), the design\nfactor varies by Class location, as follows:\nClass 1..........0.72\nClass 2..........0.60\nClass 3..........0.50\nClass 4..........0.40\nThe provisions of §192.111(b)-(d) do not require any variation from the above factors for pipe in\nriver crossings. Note, however, that §192.111(d)(2) requires that in Class 1 and 2 locations steel\npipe, including pipe risers, on platforms located offshore, or in inland navigable waters must have\na design factor of 0.50 or less.\nI hope my earlier response did not cause you any inconvenience.\nSincerely,\n/signed/\nCesar DeLeon\nDirector, Regulatory Programs\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\111\\92-02-18\n1","truncated":false,"body_characters":1328}
