any air pollutant listed in § 112(b) of the federal Clean Air Act, as amended by Subpart C of 40 

CFR Part 63. The specific version of Subpart C adopted by reference shall be that contained in the 

CFR specified in 9VAC5-60-90.

2. For the purposes of the federal Hazardous Air Pollutant Program, the source category schedule 

for standards is the schedule issued pursuant to § 112(e) of the federal Clean Air Act for

promulgating the standards issued pursuant to § 112(d) of the federal Clean Air Act and

promulgated in 40 CFR Part 63. The specific schedule adopted by reference shall be that

promulgated on February 12, 2002 (67 FR 6521).

9VAC5-60-95. Authority to implement and enforce standards as authorized by EPA. 

A. This article provides the legally enforceable mechanism to facilitate the Commonwealth's obligation 

to implement and enforce the federal MACTs as state requirements. 

B. The Commonwealth's delegated authority to implement and enforce the standards designated in 

9VAC5-60-100 as authorized by EPA is identified in the documents specified in subdivisions 1 through 5 

of this subsection. The Commonwealth's delegated authority extends only to the source categories and 

pollutants identified in the documents, and is subject to the provisions, conditions, and limitations set forth 

in the following documents:

1. Letter from W. Michael McCabe dated April 20, 1998. 

2. Letter from W. Michael McCabe dated November 19, 1998. 

3. Federal Register notice dated January 26, 1999 (64 FR 3938). 

4. Letter from Judith M. Katz dated May 30, 2001. 

5. Federal Register notice dated January 8, 2002 (67 FR 825). 

C. In its delegation notices and letters, EPA automatically delegated to the Commonwealth the 

authority to implement and enforce future MACT requirements if the Commonwealth legally adopted the 

requirements, informed EPA that it intended to enforce the standards in accordance with the terms of the 

delegation, and met other conditions. The latest letter that the Commonwealth submitted to obtain

authority to implement and enforce additional requirements is available for examination as provided in 

subsection D of this section. 

D. Copies of the documents cited in subsections B and C of this section may be examined by the 

public at the central office of the Department of Environmental Quality, 629 East Main Street, Eighth 

Floor, Richmond, Virginia between 8:30 a.m. and 4:30 p.m. of each business day. 

E. The documents cited in subsection B of this section establish the terms of the delegation to the 

Commonwealth to implement and enforce the federal MACT as authorized by EPA. As such, the

documents place requirements upon the Commonwealth, not the affected facilities; thus, the documents 

are not being incorporated by reference into the regulations of the board but are being cited for

information purposes only.
