Re: Revision to SC Air Quality Implementation Plan: Regional Haze Periodic Update 

Dear Ms. Fleming: 

L. Clarence Batts, Jr.

John 0. Hutto, Sr., MD 

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) to address the requirements of Regional Haze Rule at 40 CFR 

51.308(g) requiring periodic reports evaluating progress towards the State's Reasonable Progress Goals. 

The Department offered a public hearing for this revision on December 3, 2012. However, pursuant to 40 

CFR 51.1 02 (20 11 ), the Department did not receive a request for a hearing by the close of the comment 

period (November 26, 2012). Therefore, the Department cancelled the hearing. 

On November 26,2012, the Department received comments from Region 4 staff and has incorporated 

revisions to address those comments in this final revision. The Department will publish a final notice to 

revise the aforementioned portion of the SIP in the South Carolina State Register on January 25, 2013, at 

which time it will become state effective. I certifY that the digital copies of this letter and the attached 

documents on the enclosed CD are an exact duplicate of the paper copies. 

It is for the reasons outlined in the attachments that DHEC submits a negative declaration to the EPA 

specifYing that its Regional Haze SIP is sufficient in meeting the requirements outlined in the Regional 

Haze Rule. Furthermore, no additional controls are necessary during this, the five year progress report. 

The Department appreciates the assistance provided by you and your staff regarding the formulation of 

this plan. Should you or your staff have any questions or comments concerning this SIP revision, please 

contact Maeve S.R. Mason of the Bureau of Air Quality at (803) 898-2230 or masonmr@dhec.sc.gov.
