(2)
U.S. EPA disapproves the following portions of Rule 203(d)(5) which regulate the control of particulate matter from specific sources within the iron and steel industry: Rule 205(d)(5)(B)(ii), Rule 205(d)(5)(B)(iii), Rule 205(d)(5)(D), and Rule 205(d)(5)(K).

The redesignation request and maintenance plan meet the redesignation requirements of the Clean Air Act.
(j) Determination of Attainment.
EPA has determined, as of November 27, 2009, that the Chicago-Gary-Lake County, IL-IN PM2.5 nonattainment area has attained the 1997 PM2.5 NAAQS. This determination, in accordance with 40 CFR 51.1004(c), suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, reasonable further progress, contingency measures, and other plan elements related to attainment of the standard for as long as this area continues to meet the 1997 PM2.5 NAAQS.
