DEEP: RACT under the 2008 Ozone NAAQS

RACT under the 2008 Ozone NAAQS
{What is RACT? RACT is the lowest emission limitation that a source is capable of meeting by the application of reasonably available control technology considering technological and economic feasibility.} On July 20, 2012, Connecticut’s designation by the U.S. Environmental Protection Agency (EPA) as marginal nonattainment for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) became effective.  Under the Clean Air Act (CAA), this marginal nonattainment designation obligates DEEP to correct pre-1990 Reasonably Available Control Technology (RACT) requirements (the RACT fix-up). 
However, Connecticut is a member of the Ozone Transport Region (OTR) and is required to adopt RACT for:
(1) all volatile organic compound (VOC) sources covered by a control technique guideline (CTG); and
(2) all major non-CTG sources of oxides of nitrogen (NOx) and VOC. 
What do NOx and VOC have to do with Ozone?
{View the Current Air Quality Forecast for CT} Ground-level ozone is not emitted directly into the air by sources, but is created by chemical reactions in the air between NOx, VOC and water droplets.  These reactions are accelerated during hot sunny days and these days are typically when ozone levels reach unhealthy levels.  To learn more, EPA has created an informative video describing how ozone is formed, and you can always check the current local levels of ozone by visiting the CT Air Quality Index (AQI) website.

The OTC member states strongly believe that the implementation of RACT core principles in this document will strengthen emissions limitations, lower overall emissions, and thereby derive air quality and public health benefits.
