R. Remmel\nSenior Engineer\nCity of Palo Alto\nWater-Gas Sewer Department\nPalo Alto, California 94301\nDear Mr. Remmel:\nThis is in reply to your letter of February 11, 1971, submitting your annual report as required by\n49 CFR, Part 191 and requesting an interpretation of 49 CFR, Section 192.321(e). You state that\nyou have a good mapping system and therefore have not used an electric conductive wire for\nlocating underground plastic pipe. You further state that, as a municipal agency you control other\nstreet excavations.\n49 CFR, Section 192.321(e) was intended to be prospective in effect and apply only to new\nconstruction, not to pipe in the ground on the effective date of the regulation.\nWe would interpret your mapping systems to be \"other means\" within the regulation, if it has a\npermanent geographic reference that is not solely the location of the street.\nThank you for your interest in pipeline safety.\nSincerely,\n/signed/\nJoseph c. Caldwell\nDirector, Acting\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\321\\71-03-11\n1","truncated":false,"body_characters":1054}
