Re: Revision to South Carolina Air Quality Implementation Plan - 2009 End of Year 

Revisions 

Dear Ms. Fleming: 

The South Carolina Department of Health and Environmental Control ("Department") requests 

that the U.S. Environmental Protection Agency ("EPA") grant final approval to this revision of 

the South Carolina Air Quality Implementation Plan ("SIP"). 

The EPA promulgates amendments to federal regulations throughout each calendar year. In order 

to maintain consistency with the appropriate federal revisions, the Department annually 

incorporates relevant federal rules from the previous year. One of the 2009 federal amendments 

that the Department is incorporating into state regulations, an amendment to the definition of 

Volatile Organic Compounds ("VOCS"),' amends a section of state regulations that is part of the 

SIP. The remaining changes are to state regulations that are not part of the SIP, such as National 

Emissions Standards for Hazardous Air Pollutants. The enclosed SIP revision is the 

Department's amendment to the definition of VOCs. 

The Department published a public notice to revise the aforementioned part of the SIP in the 

South Carolina State Register on June 25, 2010. The Department held a staff-led informational 

forum (SIF) on July 26,20 10. No stakeholders attended, and the Department received no 

comments. A transcript of the SIF is included in Appendix A. 

The Department held a public hearing for this revision before the Board of Health and 

' Air Quality: Revision to Definition of Volatile Organic Compounds-Exclusion of Propylene Carbonate and 

Dimethyl Carbonate, 74 Fed. Reg. 3437. (Jan. 21,2009).
