Re: Revisions to South Carolina Air Quality Implementation Plan, 2008 Revisions to NAAQS for 

Ozone and Lead 

Dear Mr. Meiburg: 

The South Carolina Department of Health and Environmental Control (Department) requests that the United 

States Environmental Protection Agency (EPA) grant fmal approval on this revision to the South Carolina Air 

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 Department also annually reviews its state regulations and the South Carolina 

SIP. 

Among the federal revisions promulgated from January 1, 2008, through December 31, 2008, were revisions to 

the National Ambient Air Quality Standards for ozone and lead. As such, the Department has amended the 

following state regulation, which is part of our 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 Ambient Air Quality Standards (NAAQS) for the 8-hour primary and secondary standard for 

ozone; the rolling 3-month average primary and secondary standard for 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 of new and modified air pollution sources under the Prevention of Significant 

Deterioration (PSD) program for the 2008 owne standards. In addition, EPA and states will continue to 

implement the 1997 ozone standards." We are moving forward with this revision to the SC SIP for consistency 

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. 

Pursuant to S.C. Code Section, 1-23-120(G)(l), the proposed changes will not be more stringentthan federal 

rules and did not require legislative review.
