## Dee Freeman Secretary

Dear Mr. Meiburg: Pursuant to Section 18l(a)(5)of the Clean Air Act as amended (CAAA), the State of North Carolina requests that theUnited States Environmental Protection Agency (USEPA) extend 

## by one year the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) attainment date to June 15,2011,for the Charlotte-Gastonia-Rock Hill,North Carolina-South Carolina 8-Hour Ozone Moderate Nonattainment Area (referred to as the Metrolina area). Section 172(a)(2)(C)of the CAAA, allows the USEPA Administrator to extend the attainment date for one year even if the area has a 3-year design value above the standard for the attainment year, provided certain conditions exist. The conditions for the 

## extension are that an area has clean data in the designated attainment year and that the Statehas complied with all requirements and commitments in its implementation plan. TheFederal Register (FR) notice for the Phase 

## I Final Rule to Implement the 1997 8-hour ozone NAAQS (69 

## FR 2395

## I), defined clean data as the fourth highest daily 8-hour ozone average of 0.084 parts per million (ppm) or less. I ampleased to inform you that the Metrolina area has clean data for 2009. The North Carolina Division of Air Quality (NCDAQ) has certified to the USEPA that the 2009 ozone concentration data and quality assurance data are completely submitted to the USEPA's Air Quality System and that the ambient data are accurate when the quality assurance findings are taken into consideration (see attachments). Below is a table of the North Carolina ozone monitors in the Metrolina area with the observed fourth highest 8-hour ozone concentrations for the 2009 ozone season. lMonitoring Site
