The Environmental Protection Agency (EPA) is proposing to approve two state implementation plan (SIP) revisions submitted by the State of California to meet Clean Air Act (CAA or "Act") requirements for the 2008 ozone national ambient air quality standards (NAAQS) in the Imperial County nonattainment area, as follows. The EPA proposes to approve the "Imperial County 2017 State Implementation Plan for the 2008 8-Hour Ozone Standard" ("Imperial Ozone Plan" or "Plan") and the portions of the "2018 Updates to the California State Implementation Plan" ("2018 SIP Update") that address the requirement for a reasonable further progress (RFP) demonstration for the Imperial County for the 2008 ozone standards. In addition, the EPA is proposing to determine, based on a separate demonstration submitted by the State of California, that the Imperial County nonattainment area would have attained the 2008 ozone NAAQS by the "Moderate" area attainment date of July 20, 2018, but for emissions emanating from outside of the United States, and therefore would no longer be subject to the CAA requirements pertaining to reclassification upon failure to attain. If we finalize these proposed actions, the Imperial County nonattainment area would remain classified as a Moderate nonattainment area for the 2008 ozone NAAQS.
