## Abstract

In this action, EPA is approving the Inspection and Maintenance (I/M) State Implementation Plan (SIP), for Washington State. On August 21, 1995, Washington submitted SIP revision requests to the EPA to satisfy the requirements of sections 182(b)(4) and 182(c)(3) of the Clean Air Act, as amended and Federal I/M rule 40 CFR part 51, subpart S. These SIP revisions will require vehicle owners to comply with the Washington I/M program in the two Washington ozone nonattainment areas classified as ``marginal'' and in the three carbon monoxide nonattainment areas classified as ``moderate''. This revision applies to the Washington counties of Clark, King, Pierce, Snohomish, and Spokane.
