EPA is taking final action to approve, as a revision to Ohio's title V air operating permits program, revisions to Ohio's regulations for insignificant emissions units (IEUs), Ohio's regulations requiring reports of any required monitoring at least every six months and prompt reports of deviations, and other provisions of Ohio's title V regulations. In a Notice of Deficiency published in the Federal Register on April 18, 2002, EPA notified Ohio of EPA's finding that Ohio's provisions for insignificant emissions units and Ohio's regulations requiring reports of any required monitoring at least every six months and prompt reports of deviations did not meet minimum Federal requirements. Final approval of this program revision resolves the deficiency identified in the Notice of Deficiency and removes the potential for any resulting consequences, including sanctions, with respect to the April 18, 2002 NOD.
