Reference: Major New Source Review 

Dear Ms. Esher: 

Pursuant to the requirements of § 110 of the Clean Air Act, we are officially requesting 

approval of a revision to the Commonwealth of Virginia State Implementation Plan (SIP) 

approved and submitted under the authority of § 10.1-1185 of the Code of Virginia and in 

accordance with the requirements of 40 CFR Part 51 (Requirements for Preparation, Adoption, 

and Submittal of Implementation Plans). 

This revision consists of amendments to Article 8 of 9V AC5 Chapter 80, Permits for 

Major Stationary Sources and Major Modifications Locating in Prevention of Significant 

Deterioration Areas. The amendments are intended to make the state regulation consistent with 

EPA's final rule for the Phase II implementation of the 8-hour ozone standard (November 29, 

2005, 70 FR 71612) which revises the definitions of "major modification," "major stationary 

source," "regulated NSR pollutant" and "significant," and the list of exempted facilities to 

specify that nitrogen oxides are a precursor of ozone in addition to volatile organic compounds. 

This revision also enables the Commonwealth to meet its outstanding § 11O(a)(2) program 

requirements as described in "Completeness Findings for § 11O(a) State Implementation Plans 

for the 8-hour Ozone NAAQS" (March 27,2008, 73 FR 16205). The regulation amendments 

were adopted by the State Air Pollution Control Board on October 23,2008 under the authority 

of § 10.1-1308 of the Code of Virginia. 
A number of minor administrative revisions have also been made. These provisions are 

to also be considered to be part of the SIP revision. 

Enclosed are the following: 

1. A true copy of the official regulation (Revision A08) which was published in the 

Virginia Register of Regulations on November 24,2008 after being duly adopted by the State Air 

Pollution Control Board on October 23,2008, certified by the Office of the Attorney General as 

within the Board's statutory authority on October 23, 2008 and thus fully enforceable under 

Virginia law, and submitted to the Virginia Registrar on behalf of the board by the Department of 

Environmental Quality as a true and accurate copy of the duly adopted regulation on November 

3,2008, providing the evidence required by Section 2.1 (b) and (e) of Appendix V of 40 CFR Part 

51. 

2. Certification of public participation activities and compliance with state 

administrative procedures. 

3. Public participation record. 

If you have any questions or need additional information, please let us know.
