## Abstract

The Environmental Protection Agency (EPA) is determining that the Northern Wasatch Front, UT area failed to attain the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. The effect of failing to attain by the applicable attainment date is that the area will be reclassified by operation of law to "Serious" nonattainment for the 2015 ozone NAAQS on, the effective date of this final rule. This action fulfills the EPA's obligation under the Clean Air Act (CAA) to determine whether ozone nonattainment areas attained the NAAQS by the Moderate area attainment date and to publish a document in the Federal Register identifying each area that is determined as having failed to attain and identifying the reclassification.
