EPA is approving a request from the State of Indiana to redesignate Lake and Porter Counties, the Indiana portion of the Chicago-Gary-Lake County, Illinois-Indiana (IL-IN) 8-hour ozone nonattainment area, to attainment of the 1997 8-hour ozone NAAQS. In addition, EPA is approving, as a revision to the Indiana State Implementation Plan (SIP), the State's plan for maintaining the 1997 8-hour ozone NAAQS through 2020 in Lake and Porter Counties and in the Chicago-Gary-Lake County, IL-IN ozone nonattainment area. EPA is also approving the 2002 Volatile Organic Compounds (VOC) and Nitrogen Oxides (NO X ) emission inventories for Lake and Porter Counties as a SIP revision and as meeting the requirements of the Clean Air Act (CAA). Finally, EPA finds adequate and is approving the State's 2010 and 2020 VOC and NO X Motor Vehicle Emission Budgets (MVEBs) for Lake and Porter Counties.
