## Abstract

We are approving a March 18, 1999 request from Ohio for a State Implementation Plan (SIP) revision of the Stark County (Canton, Ohio) ozone maintenance plan. The maintenance plan revision establishes new transportation conformity mobile source emissions budgets for the year 2005. We are approving the allocation of a portion of the safety margin for volatile organic compounds (VOCs) and oxides of nitrogen (NO<INF>X</INF>) to the area's 2005 mobile source emissions budgets for transportation conformity purposes. This allocation will still maintain the total emissions for the area at or below the attainment level required by the transportation conformity regulations.
