Approval and Promulgation of Air 

Quality Implementation Plans; Indiana; 

Redesignation of the Indianapolis Area 

to Attainment of the 1997 Annual 

Standard for Fine Particulate Matter 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to approve 

Indiana’s request to redesignate the 

Indianapolis, Indiana nonattainment 

area (Hamilton, Hendricks, Johnson, 

Marion, and Morgan Counties) to 

attainment for the 1997 annual National 

Ambient Air Quality Standard (NAAQS 

or standard) for fine particulate matter 

(PM2.5), because the request meets the 

statutory requirements for redesignation 

under the Clean Air Act (CAA). The 

Indiana Department of Environmental 

Management (IDEM) submitted this 

request on October 20, 2009, and 

supplemented it on May 31, 2011. EPA’s 

proposed approval involves several 

additional related actions. EPA is 

proposing to make a determination that 

the Indianapolis area has attained the 

1997 annual PM2.5 standard. EPA is 

proposing to approve, as a revision to 

the Indiana State Implementation Plan 

(SIP), the State’s plan for maintaining 

the 1997 annual PM2.5 NAAQS through
