The Cincinnati-Hamilton area includes the Ohio Counties of Hamilton, Butler, Clermont, and Warren and the Kentucky Counties of Boone, Campbell, and Kenton. This determination is based on three years of complete, quality-assured, ambient air monitoring data for the 1996 to 1998 ozone seasons that demonstrate that the ozone NAAQS has been attained in the area, as well as the most recent 3-year period of data from 1997-1999, which shows the area is continuing to attain. On the basis of this determination, EPA is also determining that certain attainment demonstration requirements, along with certain other related requirements of Part D of Title 1 of the Clean Air Act (CAA), are not applicable to the Cincinnati-Hamilton area. We are also approving an exemption for the Cincinnati-Hamilton area from the nitrogen oxides (NO<INF>X</INF>) requirements as provided for in section 182(f) of the CAA. Section 182(f) establishes NO<INF>X</INF> requirements for ozone nonattainment areas. However, it also provides, in subsection 182(f)(1)(A), that these requirements shall not apply to an area if the Administrator determines that additional NO<INF>X</INF> reductions would not contribute to attainment of the ozone NAAQS in that area. Because the Cincinnati-Hamilton area is currently attaining the ozone NAAQS without benefit of additional NO<INF>X</INF> reductions, we are granting the area a NO<INF>X</INF> exemption. As a result, the Cincinnati-Hamilton area will no longer be subject to the section 182(f) NO<INF>X</INF> requirements; however, all NO<INF>X</INF> controls previously approved for the area by EPA must continue to be implemented. We are also approving the State of Ohio Environmental Protection Agency's (OEPA) and the Commonwealth of Kentucky Natural Resources and Environmental Protection Cabinet's (Cabinet) requests to redesignate the Cincinnati-Hamilton area to attainment of the 1-hour ozone NAAQS. The original redesignation request from OEPA, dated June 28, 1999, was received on July 2, 1999, and completed on December 22, 1999. The Cabinet's redesignation request to EPA was dated October 29, 1999. In approving these redesignation requests, EPA is also approving, as revisions to the Ohio and Kentucky State Implementation Plans, the States' plans for maintaining the 1-hour ozone standard for the next 10 years. 65 FR 37879 https://www.govinfo.gov/app/details/FR-2000-06-19/00-15294 00-15294 fr19jn00-10 6560-50-P OH-132-2 KY-116-2 KY-84-2 FRL-6717-1 https://www.govinfo.gov/app/details/FR-2000-06-19/00-15294 https://www.govinfo.gov/content/pkg/FR-2000-06-19/html/00-15294.htm https://www.govinfo.gov/content/pkg/FR-2000-06-19/pdf/00-15294.pdf Environmental Protection Air Pollution Control Nitrogen Oxides Ozone Reporting and Recordkeeping Requirements Volatile Organic Compounds 22 p. 37879 37900 65 FR 37879 Title 40 Part 52 40 CFR Part 52 Title 40 Part 81 40 CFR Part 81 Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Ohio and Kentucky; Federal Register Vol. 65, Issue RULE 00-15294 ENVIRONMENTAL PROTECTION AGENCY 2000-07-05 OH-132-2 KY-116-2 KY-84-2 FRL-6717-1 6560-50-P 00-15294 Final rule.
