T he 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 (NO X ) and Sulfur Dioxide (SO 2

) 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 (PM 2.5 ); 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 NO X Budget Trading Program And CAIR NO X And SO 2 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 (PM 2.5 ).

• 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 (NO X ) and Sulfur Dioxide (SO 2 ) Budget Trading Program General Provisions , to incorporate by reference recentFederal 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:
