BACKGROUND: 

Sections 182(b)(2), (c), and (f) of the federal Clean Air Act (the Act) require ozone nonattainment areas to implement reasonably available control technology (RACT) emission standards for major sources of ozone precursors, volatile organic compounds (VOCs), and nitrogen oxides (NOx). Section 182(c) of the Act requires areas classified as "serious" or higher nonattainment for ozone to submit a State Implementation Plan (SIP) that includes a RACT analysis for major stationary sources. The U.S. Environmental Protection Agency (EPA)’s 2015 Ozone National Ambient Air Quality Standards Implementation Rule requires air pollution control agencies to submit a SIP revision that meets the Act’s VOC and NOx RACT requirements for any nonattainment area classified as “moderate” or higher (40 CFR Part 51.1312(a)).

Section 120 will require major stationary sources of NOx and/or VOCs in ozone nonattainment areas to submit a major source RACT demonstration when the EPA Administrator classifies or reclassifies an area as moderate, serious, severe, or extreme nonattainment for ozone.

The attached Technical Support Document provides context and explains the proposed new regulation to facilitate enforcement.
