Hurley\nIllinois Commerce Commission\n527 East Capitol Avenue\nSpringfield, IL 62701\nDear Chairman Hurley:\nThank you for your continued interest in pipeline safety. In your July 14, 2005 letter you notified our office that\nthe Illinois Commerce Commission (Commission) granted an Interim Order in the form of a partial waiver of 49 CFR\n192.481(a), to the Union Electric Company d/b/a AmerenUE, Central Illinois Public Service Company d/b/a AmerenaPS,\nCentral Illinois Light Company d/b/a AmerenCILCO, and Illinois Power Company dlb/a AmerenlP (collectively Petitioners).\nThe Interim Order which became effective September 21, 2005 also required the Petitioners to increase the\nfrequency of their distribution leakage-surveys governed by § 192.723(b)(2). On September 19, 2005 the Pipeline and\nHazardous Materials Safety Administration (PHMSA) notified your office of its objection to the waiver and your Interim\nOrder was stayed.\nOn February 26, the Commission appealed PHMSA's decision and submitted a second Interim Order containing\nnew information from the Petitioners to show that granting a partial waiver of § 192.481(a) provides an equivalent level\nof safety. PHMSA re-evaluated the Commission's Interim Order as well as the new information provided by the\nCommission. Based on this new information as well as sound engineering and industry best practices, PHMSA imposes\nthe following conditions in granting this waiver:\n1. Outside of business districts, atmospheric corrosion control monitoring must be conducted at least once\nevery four calendar years at intervals not exceeding 51 months.\n2. Inside of business districts, atmospheric corrosion control monitoring must be conducted at least once\nevery calendar year at intervals not exceeding 15 months.\n3. Operators must identify, inspect, and notify the Commission of those areas requiring atmospheric\ncorrosion control monitoring more frequently than once every three calendar years. These areas include \"hot\nspots\" where there are greater atmospheric corrosion rates.\na. Above ground pipelines where there is greater exposure to road salts and chemicals;\nb. Areas where pipelines could have accelerated atmospheric corrosion due to industrial chemicals\nin the atmosphere;\nc. Pipelines that may experience sweating due to pressure drop, such as regulator stations,\nmetering correctors, and large customer's regulator/meter sets;\nd. Inside regulator/meter sets that are subject to corrosive environments; and\ne. Other areas that show accelerated atmospheric corrosion.\nPHMSA does not object to the Commission's Interim Order provided the above conditions are agreed upon and\nmade part of the waiver. If you have any questions, concerns, or comments, please feel free to contact me or James\n\n<<<PAGE 2>>>\n\nReynolds, General Engineer at 202-366-2786.\nSincerely,\nTheodore L.
