Clean Air Act Final Approval Of Amendments to Title V Operating Permits Program; Pima County Department of Environmental Quality, Arizona

The EPA is promulgating final approval of the following revisions to the operating permits program submitted by the Arizona Department of Environmental Quality (``DEQ'') on behalf of the Pima County Department of Environmental Quality (``Pima'' or ``County''): a revision to the fee provisions; and a revision that will defer the requirement for minor sources subject to standards under sections 111 or 112 of the Act to obtain title V permits, unless such sources are in a source category required by EPA to obtain title V permits. EPA is also promulgating final approval under section 112(l) of Pima's program for delegation of section 112 standards as they apply to sources not required to obtain a title V permit. EPA took final action on Pima's title V operating permits program on October 30, 1996 (61 FR 55910). However, because Pima's title V program contains certain flaws, EPA did not fully approve it, but instead granted the program an ``interim approval.'' Under its interim approval, Pima is required to adopt and submit program changes to EPA that will correct its program flaws. The program revisions being approved in this document do not address the program issues identified by EPA. This final action approving revisions to Pima's title V program therefore does not constitute a full approval of Pima's title V program.
