Approval and Promulgation of Air Quality Implementation Plans; New York; Determination of Attainment of the 2008 8-Hour Ozone National Ambient Air Quality Standard for the Jamestown, New York Marginal Nonattainment Area

Résumé

The Environmental Protection Agency (EPA) is finalizing a determination that the Jamestown, New York Marginal Nonattainment Area (Jamestown Area or Area) has attained the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). This determination is based upon complete, quality-assured, and certified ambient air monitoring data that shows the Area has monitored attainment of the 2008 8-hour ozone NAAQS for both the 2012-2014 and 2015-2017 monitoring periods. This action does not constitute a redesignation to attainment. The Jamestown Area will remain nonattainment for the 2008 8-hour ozone NAAQS until such time as EPA determines that the Jamestown Area meets the Clean Air Act (CAA) requirements for redesignation to attainment, including an approved maintenance plan. This action is being taken under the CAA.
