Abstract
The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the Illinois Environmental Protection Agency (IEPA) on December 2, 2013. The state rule revisions update Illinois' ambient air quality standards for sulfur dioxide (SO<INF>2</INF>), ozone, nitrogen dioxide (NO<INF>2</INF>), lead, fine particulate matter (PM<INF>2.5</INF>), particulate matter (PM<INF>10</INF>), and carbon monoxide (CO) and bring them up to date (through 2012) with EPA- promulgated National Ambient Air Quality Standards (NAAQS). The SIP revision also adopts EPA-promulgated monitoring methods and test procedures for the revised state air quality standards.
