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 the United States Environmental Protection Agency (USEPA) extend by one 

year the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) attainment date to 

June 15,201 1, 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 State has complied with all requirements and commitments in its implementation 

plan. 

The Federal 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 am pleased 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.

commitments pertaining to the area in the applicable ozone implementation plan. Furthermore, the 

NCDAQ certifies that the State has complied with all requirements and commitments in the State 

Implementation Plan that has been submitted to the USEPA for approval. 

The NCDAQ believes that the State has met the requirements of Section 172(a)(2)(C) of the 

CARA and &;ectfully requests that you grant the Charlotte-Gastonia-Rock Hill, North CarolinaSouth Carolina 8-how hone nonattainment area a one-year extension of the attainment date for the 

1997 8-hour ozope.NAAQS. If you should have any questions, please contact Laura Boothe of my

daie is to support a separate request by the Division of Air Quality to extend the deadline for attaining 

the 1997 8-hour ozone standad in the Charlotte-Gastonia-Rock 1311 MSA. For the same purpose, on 

November 24.2009, Jeff Francis certified three ozone monitors operated by Reporting Organization
