Re: Final Amendments to the South Carolina Air Quality Implementation Plan (SIP): Regulation Clean-Up 

Dear Ms. Keyes Fleming: 

The Department of Health and Environmental Control (Department) is pleased to provide amendments to the South 

Carolina SIP for fmal approval. The Department has conducted a review of current air quality regulations to ensure that 

we are efficiently and effectively meeting our goals of promoting and protecting the public health and the environment. 

An internal Regulation Clean-Up Workgroup was created to formulate ways to evaluate air quality regulations to provide 

clarification, delete or update obsolete requirements, and correct typographical errors where necessary. 

The Department has also held external stakeholder meetings to take recommendations and comments on those regulatory 

amendments identified by the Regulation Clean-Up Workgroup. Through these stakeholder meetings, the Department 

developed amendments to S. C. Regulation 61-62 and Regulation 61-86.1 by consensus. Underline/strikeout and clean 

copies of these regulations are included as Attachment 1. Comments received as a result of stakeholder meetings and EPA 

consultation, along with Department responses, are included as Attachment 2. 

The Department has amended R. 61-62 and the SIP. In particular, the Department has amended R. 61-62.1 , Definitions 

and General Requirements, to update and correct definitions and permit requirements; R. 61-62.5, Standard 1, Emissions 

From Fuel Burning Operations, to exclude the requirement for natural gas fired units to maintain a log of periods of 

startup and shutdown; R. 61-62.5, Standard 2, Ambient Air Quality Standards, to remove the standard for Total Suspended 

Particle (TSP) and update exceedance limitation for the carbon monoxide (CO) standard; R.61-62.5, Standard No. 4, 

Emissions from Process Industries, to remove the obsolete requirement of stack testing for Total Reduced Sulfur (TRS) at 

facilities that are already required to have a continuous emissions monitoring system (CEMS) installed and to modify the 

regulatory strategy for cotton gins; and clarify the definition for major source threshold throughout 61-62. The 

Department also has deleted R. 61-62 .5, Standard 6, Alternative Emission Limitation Options ("Bubble''); and updated the 

entirety ofR. 61-62 to correct typographical errors, provide clarification, and delete or update obsolete requirements. 

A public notice to revise the SIP was published in the State Register on June 25, 2010. A staff-conducted informational 

forum (SIF) on the proposed revisions was held on July 26, 2010. Some stakeholders attended, but no comments were 

received. A public hearing before the Board of Health and Environmental Control was held on November I 0, 2010. No 

comments were received at the public hearing. Some of these proposed changes were not mandated by the federal 

government. As such, pursuant to S.C. Code Section, 1-23-120(H)(1) these amendments required legislative review. 

These amendments were passed by the South Carolina State Legislature on May 11 , 2011. A final notice to revise the 

aforementioned portion of the SIP was published in the State Register on May 27, 2011 , at which time it became state 

effective. Notices of Drafting; Notice of Proposed Regulation; transcript and sign-in sheet of the SIF; transcript of the 

public hearing; and Notice of Final Regulation are included in Attachment 3.

Also included in this package (as Attachment 4) is a 11 0(1) demonstration. This attachment evaluates the proposed 

changes to the regulatory strategy for cotton gins and demonstrates that these changes are at least as stringent (in fact, 

more stringent) as the previous version of the regulation. 

The Department appreciates the assistance provided by your staff regarding the formulation of these amendments. The 

Department certifies that the electronic version of this SIP submission is identical to the hard copy. Please contact Mr. 

Andrew 0 . Hollis of the Bureau of Air Quality at 803-898-4196, or hollisao@dhec.sc.gov with any questions or 

comments concerning this SIP revision.
