Re: South Carolina Air Quality Implementation Plan Revision - Regional Haze 

M. David Mirchd, MD

Dear Mr. Pidmer: 

The South Carolina Department of Health and Environmental Control (the Department) has amended 

the Slate bnplementation Plan (SIP) to meet obligations of the United States Environmental 

Protection Agency (EFA) under Section 169A of the Clean Air Act (CAA). This section requires 

mates to amend their SIPs to provide for the prevention and remediation of manrnade air pollution, 

which conbi butes to the visibility impairment of Class I Federal areas throughout the country. 

In 1980, the EPA promulgated regulations to address visibility impairment that is "reasonably 

attributable" to one or a small group of sources located across a broad geographic area (referred to as 

regional haze). However, the EPA deferred action on regional haze regulations until monitoring, 

model i ng, and scientific knowledge about the relationship between pollutants and visibility effects 

irnpro\ cd. In 1993, at the recommendation of a National Academy of Science (NAS) report, the 

EPA began conducting research into control technologies available for taking regulatory action to 

irnprcn c and protect visibility in Class I areas. 

On Jul j 3 1 : 1997, the EPA published proposed amendments to the 1980 regulations to set forth a 

program to address regional haze [62 FR 41 1381. On July 1, 1999, and July 6, 2005, the EPA 

promulgated two rules known as the "Regional Haze Regulation (Regional Haze Rule)" and the 

''Regio~xal Haze Regulations and Guidelines for Best Available Retrofit Technology (BART) 

Determinations" (also referred to as the BART Rule), respectively. The Regional Haze Rule calls for 

States to establish goals and strategies for improving visibility in all of the country's 156 Class I 

nationctl parks and wilderness areas. Cape Romain, South Carolina is one such Class I area. The 

EPA is requiring all states areas to revise their SIPs to reduce emissions of sulfur dioxide (SOz), 

oxides of nitrogen (NO,), and particulate matter--especially fine particulate matter (PM2.5)--all of 

which contribute to regional haze and affect Class I areas. States must also address BART in their 

regional haze SIPs. SIl's addressing Regional Haze and BART requirements are due to the EPA no 

later t11:m December 17,2007. The Department has determined that no BART-eligible facilities in

December 17,2007 

South Carolina will have to undergo Mer analysis for BART, as all of these facilities successfidly 

demonstrated exemption. One facility, DAK Americas, LLC., opted to accept emission limitations 

in its Part 70 Air Quality Operating Permit so as to demonstrate exemption from BART. 'please see 

Condition 5.E.34 and 6.B.51 in the footnote below. 

Enclosed with this letter is a copy South Carolina's proposed Regional Haze SIP and its appendices, 

as well electronic versions of each. The plan and appendices constitute a SIP revision and include 

measures necessary to make reasonable progress toward the national goal. These measures include a 

long-term strategy for the reduction of visibility impairment that examines emission reductions 

required by other Clean Air Act programs, the possible application of BART, and ang. additional 

control measures identified as reasonable by a four fixctor analysis. 

19 staff-led public hearing to discuss this plan was held on November 26,2007. No comments were 

received the clay of the hearing. However, several written comments were received at the conclusion 

ol'the public comment period on December 12,2007. Those comments deemed significant by the 

Ilepartment were used to modifl the SIP and are addressed within Appendix J. The Department 

requests find approval fiom EPA on the revision to the South Carolina SIP. 

The Dcpartrnent appreciates the assistance provided by EPA staklFregarding the formulation of this 

plan. S liould you or your staff have any questions or comments coxmming this SIP revision, please 

contact Stacey Gardner of my staff at (803) 898-4287 or gardnesrO;dhee.sc.~ov.
