Washington Street\nPhoenix, AZ 85007-2996\nDear Mr. Fronterhouse:\nThis responds to your letter of October 8, 1999, concerning a request by the City of\nPhoenix Aviation Department for a finding under 49 CFR 195.120(b)(7). This regulation\npermits us to find that particular piping is impracticable to design and construct to\naccommodate the passage of instrumented internal inspection devices.\nThe request involves a 12-inch hydrant piping system that is under construction around\nTerminal 4, N-1 Concourse, at the Sky Harbor International Airport. Although you\nrecommended that we grant the request, we believe the request is unnecessary. Fuel\ndistribution systems on airport grounds are akin to in-plant piping systems that are\nexcluded from Part 195 under § 195. 1 (b)(7) or terminal facilities that are excluded\nunder§195.1(b)(8). Because of the similarity, we do not think such systems come under\nthe safety standards in 49 CFR Part 195.\nAlso, please note that requests for findings under § 195.120(b)(7) are not handled like\nwaiver requests. Under our procedures in 49 CFR 190.9, after receiving a state agency\nrecommendation on a request for finding involving an intrastate pipeline, we have only\n10 business days to change the recommendation or else it becomes the final decision.\nSincerely,\nRichard Felder\nAssociate Administrator for Pipeline Safety","truncated":false,"body_characters":1631}
