State Implementation Plan 

for 

South Carolina 

Prepared by 

South Carolina Department of Health and Environmental Control 

Bureau of Air Quality 

December 2008 
EXECUTIVE SUMMARY 

Introduction 

The United States Environmental Protection Agency (EPA) promulgates amendments to Federal 

Regulations throughout each calendar year. In order to maintain consistency with the 

appropriate Federal revisions, the South Carolina Department of Health and Environmental 

Control (Department) also annually reviews its State Regulations and South Carolina Air Quality 

Implementation Plan (also known as the State Implementation Plan or SIP). 

Among the revisions being proposed are amendments to R. 61-62.60, South Carolina Designated 

Facility Plan and New Source Performance Standards (NSPS), R. 61-62.61, National Emission 

Standards for Hazardous Air Pollutants (NESHAP), R. 61-62.63, National Emission Standards 

for Hazardous Air Pollutants (NESHAP) for Source Categories, R. 61-62.70, Title V Operating 

Permit Program, R. 61-62.72, Acid Rain, and R. 61-62.96, Nitrogen Oxides (NOX) and Sulfur 

Dioxide (SO2) Budget Trading Program General Provisions, to incorporate recent Federal 

amendments promulgated during the period from January 1, 2007, through December 31, 2007. 

The Department also proposes to amend R. 61-62.1, Definitions and General Requirements, to 

incorporate amendments to the definition of Volatile Organic Compounds (VOCs) promulgated 

by the EPA on January 18, 2007; R. 61-62.5, Standard No. 2, Ambient Air Quality Standards, to 

respectively adopt the Federal change in the National Ambient Air Quality Standard (NAAQS) 

for the 24-hour primary standard for fine particulate matter (PM2.5); make corrections to 

Standard No. 5, Volatile Organic Compounds; and make regulation citation corrections to R. 61-

62.5, Standard No. 3, Waste Combustion and Reduction, R. 61-62.5, Standard No. 3.1, 

Hospital/Medical/Infectious Waste Incinerators (HMIWI), and R. 61-62.70, Title V Operating 

Permit Program. 

Of these recent Federal amendments, several, including clarification, guidance and technical 

amendments, also apply to the South Carolina State Implementation Plan. These amendments 

include the National Primary And Secondary Ambient Air Quality Standards; Requirements For 

Preparation, Adoption, and Submittal of Implementation Plans; and NOX Budget Trading 

Program And CAIR NOX And SO2 Trading Programs For State Implementation Plans. As such, 

the Department proposes to also amend the State Implementation Plan to adopt the 

corresponding recent Federal amendments: 

 

• On January 18, 2007, the EPA promulgated revisions to the definition of Volatile 

Organic Compounds (VOCs) to add HFE-7300 to the list of compounds excluded from 

the definition. The Department proposes to amend R. 61-62.1, Definitions and General 

Requirements, to incorporate this amendment to the definition of VOCs. 

• The Department proposes to amend R. 61-62.5, Standard No. 2, Ambient Air Quality 

Standards, to respectively adopt the Federal change in the National Ambient Air Quality 

Standard (NAAQS) for the 24-hour primary standard for fine particulate matter (PM2.5). 

• On October 19, 2007, the EPA promulgated revisions to the Federal Clean Air Interstate 

Rule (CAIR). Pursuant to EPA correspondence received on February 20, 2008, the 

Department proposes to amend R. 61-62.96, Nitrogen Oxides (NOX) and Sulfur Dioxide 

(SO2) Budget Trading Program General Provisions, to incorporate by reference recent 

2007 End-of-the-Year Revision - 1
Federal amendments to the relevant subparts of the Federal Clean Air Interstate Rule 

(CAIR). 

The Department is also proposing to correct previous omissions to Standard No. 5, Volatile 

Organic Compounds. 

The proposed amendments were reviewed internally by appropriate Department staff prior to 

seeking initial Board approval to public notice. 

The Department proposes to amend Regulation 61-62, Air Pollution Control Regulations and 

Standards, and the SIP to incorporate new Federal requirements and necessary corrections and 

clarifications into the existing regulations. Pursuant to S.C. Code Section, 1-23-120(H)(1), the 

proposed amendments are necessary to maintain consistency with Federal rules and will not 

require legislative review. 

On June 12, 2008, the Board granted staff initial approval to public notice the proposed 

amendments in the State Register to provide opportunity for public comment and to conduct a 

staff informational forum. A Notice of Proposed Regulation was published in the State Register

on June 27, 2008 (Document No. 3224). Notice of these proposed regulations, including actual 

text changes, was published on the Department’s website. No comments were received during 

the public comment period. 

On July 28, 2008, a staff-led informational forum was held. One member of the regulated 

community was present. A summary of these comments has been included as a transcript in 

Appendix A. Because these comments were primarily aimed at clarifying the need for revision, 

no changes were made to the final regulation published in the State Register. 

A public hearing before the Board of Health and Environmental Control was held on October 9, 

2008. No comments were received. A transcript of this meeting is included as Appendix B. A 

final notice to revise the aforementioned portions of the SIP was published in the State Register

on October 24, 2008. 

The SIP amendment consists of both a clean copy and highlight strikeout version of the text of 

the amendments to Regulation 61-62, Air Pollution Control Regulations and Standards and the 

SIP, as well as the following documents:
