| E9-23042 | Determination of Attainment, Approval and Promulgation of Air Quality Implementation Plans; Indiana | Proposed Rule | EPA is proposing to make a determination, under the Clean Air Act (CAA), that the Chicago-Gary-Lake County, Illinois-Indiana (IL-IN) ozone nonattainment area has attained the 1997 eight-hour ozone National Ambient Air Quality Standard (NAAQS). This determination is based on complete, quality-assured ambient air quality monitoring data for the period of 2006-2008. Preliminary data for 2009 show that the area continues to attain the standard. EPA is also proposing to approve a request from the State of Indiana to exempt sources of Nitrogen Oxides (NO<INF>X</INF>) in Lake and Porter Counties from CAA requirements for Reasonably Available Control Technology (RACT). The State's NO<INF>X</INF> RACT waiver request is based on the most recent three years of complete, quality-assured ozone monitoring data, which demonstrate that additional reduction of NO<INF>X</INF> emissions would not contribute to attainment of the 1997 eight-hour ozone NAAQS in the Chicago-Gary-Lake County, IL-IN area. This action proposes to approve the State's request for a waiver from the NO<INF>X</INF> RACT requirements for Lake and Porter Counties under the CAA. In the Final Rules section of this Federal Register, EPA is deferring the imposition of sanctions for the State's failure to submit required NO<INF>X</INF> RACT regulations based on this proposed attainment determination while we complete action on the proposed NO<INF>X</INF> RACT waiver. This deferral of sanctions will continue unless EPA determines that the area is no longer attaining the 1997 eight-hour ozone NAAQS. However, if EPA proposes and takes final action in the future to redesignate the area to attainment, such action will permanently stop the sanctions clock. | 2009-09-24 | 2009 | 9 | https://www.federalregister.gov/documents/2009/09/24/E9-23042/determination-of-attainment-approval-and-promulgation-of-air-quality-implementation-plans-indiana | https://www.govinfo.gov/content/pkg/FR-2009-09-24/pdf/E9-23042.pdf | Environmental Protection Agency | 145 | EPA is proposing to make a determination, under the Clean Air Act (CAA), that the Chicago-Gary-Lake County, Illinois-Indiana (IL-IN) ozone nonattainment area has attained the 1997 eight-hour ozone National Ambient Air Quality Standard (NAAQS).
