### w Re: Revisions to South CarolinaAir Quality Implementation Plan, 2008 Revisions to NAAQS for Ozone andLead Dear Mr. Meiburg: The South CarolinaDepartment ofHealth and Environmental Control (Department) requests that the United States Environmental Protection Agency (EPA) grantfmal approval on this revision tothe South CarolinaAir Quality Implementation Plan (also known as the State Implementation Plan or SIP). The EPA promulgates amendments to federal regulations throughout each calendar year. In order to maintain consistency with the appropriate federal revisions, the Departmentalso annuallyreviews its state regulations andthe SouthCarolina SIP. Amongthe federal revisions promulgatedfrom January 1, 2008, throughDecember 31, 2008, wererevisionsto the National Ambient Air Quality Standards for ozone and lead. As such, the Department has amended the following state regulation, which is part ofour federally approved SIP, to adopt the corresponding federal revisions:
• R. 61-62.5, Standard No. 2, 

### Ambient Air Quality Standards, to adopt the federal change in the National AmbientAir Quality Standards (NAAQS) forthe 8-hourprimary and secondary standard for ozone; the rolling 3-month average primary and secondary standardfor lead, and

### to remove the 1-hour primary and secondary standard for ozone. On September 16, 2009, EPA announced that it "will propose to stay the 2008 standards for the purpose of attainment (meeting standards) and nonattainment (not meeting standards) area designations. EPA will continue to require permitting ofnew and modified air pollution sources underthe Prevention ofSignificant Deterioration (PSD) program for the 2008 

### owne standards. In addition, EPA and states will continue to implementthe 1997 ozone standards." We are moving forward with this revision tothe SC SIP forconsistency purposes. Any future changes to the 

### owne standard 

### will be incorporated into state regulations though our normal process once a new ozone standard is promulgated by EPA. Pursuantto S.C. Code Section, 1-23-120(G)(l),the proposed changes 

### will notbe more stringentthan federal rules and did not require legislative review.
