The Environmental Protection Agency (EPA or "Agency") is proposing to determine that the Imperial County nonattainment area would have attained the 2015 ozone national ambient air quality standard (NAAQS) by the August 3, 2021 "Marginal" area attainment date, but for emissions emanating from outside the United States. If we finalize this proposed action, the Imperial County nonattainment area would no longer be subject to the Clean Air Act (CAA) requirements pertaining to reclassification upon failure to attain and therefore would remain classified as a Marginal nonattainment area for the 2015 ozone NAAQS. This action, when finalized, will fulfill the EPA's statutory obligation to determine whether the Imperial County ozone nonattainment area attained the NAAQS by the attainment date.
The agency’s own summary, as published.
