Stone, P.E.\nChief, Gas Pipeline Safety\nState of Ohio\nPublic Utilities Commission\n180 East Broad Street\nColumbus, Ohio 4366-0573\nDear Mr. Stone:\nI apologize for the delay in answering your April 1 letter regarding the application of 49 CFR\n192.199(g) to an East Ohio Gas Company vault.\nWe have examined the photographs and drawings of the vault, and believe that unless the\ninstallation is \"grandfathered\" or additional overpressure protection is provided elsewhere, it is\nviolation of 49 CFR 192.199(g). The violation would be due to insufficient separation between\nthe district regulator and the other regulators or the lack of any other means of protection, such as\na barrier to prevent a potential explosion in the vault from damaging all the regulators.\nSincerely,\n/signed/\nRichard L. Beam\nDirector\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\199\\87-08-10\n1","truncated":false,"body_characters":895}
