## Abstract

EPA is making an interim final determination to stay the imposition of offset sanctions and to defer the imposition of highway sanctions based on a proposed approval of revisions to the San Joaquin Valley portion of the California State Implementation Plan published elsewhere in this Federal Register. The revisions concern the Clean Air Act nonattainment area contingency measure requirement for the 1997 annual and 24-hour national ambient air quality standards for fine particulate matter (PM<INF>2.5</INF>) in the San Joaquin Valley.
