Approval and Promulgation of Air Quality Implementation Plans; Oregon; Correcting Amendment

EPA is taking direct final action to correct an error in the instructions amending the Code of Federal Regulations in the notice which approved the removal of Oregon's control technology guidelines for perchloroethylene (perc) dry cleaning systems and related definitions and provisions, published on December 1, 2004. Perc is a solvent commonly used in dry cleaning, maskant operations, and degreasing operations. In the document published on December 1, 2004 (69 FR 69823), EPA inadvertently listed an incorrect State effective date in the incorporation by reference section which listed revised provisions of the Oregon Administrative Rules. This action corrects the erroneous date so that the appropriate version of the Oregon Administrative Rules is incorporated by reference.
