J. Hendrickson, Director\nUtility Safety Section\nState Of Indiana Public Service Comm.\n901 State Office Building\nIndianapolis, Indiana 46204\nDear Mr. Hendrickson:\nThank you for your letter of October 30, 1970, requesting an interpretation of 49 CFR, Section\n192.199(g).\nYou are correct that one method of compliance is to locate a regulator and pressure limiting\ndevice in separate vaults if below grade or separated by a reasonable distance if above grade.\nHowever, there may be other means of accomplishing this result which may be appropriate or\ndesirable in a particular situation.\nThe problem of a long control line on a monitor regulator is recognized but there are steps that\ncan be taken to provide a protection for the control line; such as, locating the control line in the\nsame ditch and slightly below the main line or using heavy wall pipe for the control line.\nIf we can be of further assistance, please do not hesitate to ask.\nSincerely,\n/signed/\nJoseph C. Caldwell\nDirector, Acting\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\199\\70-11-30\n1","truncated":false,"body_characters":1082}
