determining compliance with emission limits, VOC will be measured by the approved test methods. 

Where such a method also inadvertently measures compounds with negligible photochemical reactivity, 

an owner or operator may exclude these negligibly reactive compounds when determining compliance 

with an emissions standard. 

The following compound(s) are VOC for purposes of all recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements which apply to VOC and shall be uniquely 

identified in emission reports, but are not VOC for purposes of VOC emissions limitations or VOC 

content requirements: t-butyl acetate (TBAC or TBAc). 

R.61-62.5, Standard No. 2 –Ambient Air Quality Standards: 

Regulation 61-62.5, Standard No. 2, Section VI.D.3 shall be revised as follows: 

The following table constitutes the ambient air quality standards for the State of South Carolina. The 

analytical methods to be used will be those applicable Federal Reference Methods published in 40 CFR 

50, Appendices A-N as revised July 18, 1997. In the case of fluorides either the double paper tape 

sampler methods (ASTM D-3266-79) or the sodium bicarbonate-coated glass tube and particulate filter

(i) For a unit that is a CAIR NOX Ozone Season unit under §96.304 on the later of November 15, 1990, or 

the date the unit commences commercial operation as defined in paragraph (1) of this definition and that 

subsequently undergoes a physical change (other than replacement of the unit by a unit at the same 

source), such date shall remain the date of commencement of commercial operation of the unit, which 

shall continue to be treated as the same unit. 

(ii) For a unit that is a CAIR NOX Ozone Season unit under §96.304 on the later of November 15, 1990, 

or the date the unit commences commercial operation as defined in paragraph (1) of this definition and 

that is subsequently replaced by a unit at the same source (e.g., repowered), such date shall remain the 

replaced unit’s date of commencement of commercial operation, and the replacement unit shall be treated 

as a separate unit with a separate date for commencement of commercial operation as defined in 

paragraph (1) or (2) of this definition as appropriate. 

(2) Notwithstanding paragraph (1) of this definition and except as provided in §96.305, for a unit that is 

not a CAIR NOX Ozone Season unit under §96.304 on the later of November 15, 1990, or the date the 

unit commences commercial operation as defined in paragraph (1) of this definition, the unit’s date for 

commencement of commercial operation shall be the date on which the unit becomes a CAIR NOX Ozone 

Season unit under §96.304. 

(i) For a unit with a date for commencement of commercial operation as defined in paragraph (2) of this 

definition and that subsequently undergoes a physical change (other than replacement of the unit by a unit 

at the same source), such date shall remain the date of commencement of commercial operation of the 

unit, which shall continue to be treated as the same unit. 

(ii) For a unit with a date for commencement of commercial operation as defined in paragraph (2) of this 

definition and that is subsequently replaced by a unit at the same source (e.g., repowered), such date shall 

remain the replaced unit’s date of commencement of commercial operation, and the replacement unit 

shall be treated as a separate unit with a separate date for commencement of commercial operation as 

defined in paragraph (1) or (2) of this definition as appropriate. 

“Commence operation” - (a) For all units “commence operation” means: ... 

“Fossil-fuel-fired” - (a) For a unit subject to 96.304 (a)(1)(i), (a)(2) or (b), “fossil-fuel-fired” means with 

regard to a unit, combusting any amount of fossil fuel in any calendar year. 

(b) ... 

2007 End-of-the-Year Revision, Clean Copy - 5
(1) For units that commenced operation before January 1, 1996, the combination of fossil fuel, alone or in 

combination with any other fuel, where fossil fuel actually combusted comprises more than 50 percent of 

the annual heat input on a Btu basis during 1995, or, if a unit had no heat input starting in 1995, during 

the last year of operation of the unit prior to 1995.

 (2) For a CAIR NOx Ozone Season allowance allocation under section 96.341(b)(2), the 

allowances will be determined using the unit’s baseline heat input equal to the unit’s single highest 

adjusted control period heat input for the years that are five, six, seven and eight years before the first 

year of the control periods for which the CAIR NOx Ozone Season allowance allocation is being 

calculated.
