On May 4, 2007 AGA submitted comments on EPA's proposal to amend Part 63 to overrule the Once-In, Always-In (OIAI) Policy, which was originally adopted in a 1995 guidance memorandum on which the agency did not give notice or seek comment. These comments note that AGA applauds EPA’s proposed amendments repeal the OIAI policy. This reform, with the clarifications we suggested in our comments, will promote voluntary emission control projects and pollution prevention that will help reduce HAP emissions in a manner that is consistent with the plain language of Clean Air Act section 112.
