## Abstract

The Environmental Protection Agency (EPA) is approving, as a State Implementation Plan (SIP) revision, Wisconsin's certification that its SIP satisfies the nonattainment new source review (NNSR) requirements of the Clean Air Act (CAA) for the 2008 ozone National Ambient Air Quality Standard (NAAQS). The State's submittal is in response to EPA's February 3 and December 11, 2017, Findings of Failure to Submit (FFS) final rule, which found that Wisconsin failed to satisfy CAA requirements for implementation of the 2008 ozone NAAQS in nonattainment areas.
