The Environmental Protection Agency (EPA) is proposing to determine that the deficiency that formed the basis for a disapproval of the contingency measures submitted for the San Joaquin Valley nonattainment area for the 1997 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards has been corrected. The proposed determination is based on the Agency's approval of revisions to the California State Implementation Plan that include regulations establishing standards and other requirements relating to the control of emissions from new on-road and new and in-use off-road vehicles and engines and a finding that the purposes of the contingency measure requirement, as applicable to the San Joaquin Valley based on its initial designation as a nonattainment area for the 1997 PM<INF>2.5</INF> standards, have been fulfilled. If finalized as proposed, the sanctions clocks triggered by the disapproval will be permanently stopped.
