A. No owner or other person shall cause or permit to be discharged from any affected facility any nitrogen oxides (NO_X) emissions in excess of that resultant from using RACT.

B. Unless the owner demonstrates otherwise to the satisfaction of the board, facilities to which the presumptive RACT provisions of 9VAC5-40-7430 are applicable shall comply with the provisions of subsection A of this section by the use of presumptive RACT.

C. The provisions of this section apply to all facilities that (i) are within a stationary source in the emissions control areas specified in Table 4-51E and (ii) are within a stationary source that has a theoretical potential to emit at the applicable source thresholds specified in Table 4-51E.

TABLE 4-51E. Notification and Compliance Dates for Facilities Located in NOX Emissions Control Areas for Which There is No Presumptive RACT.

TABLE 4-51F. Notification and Compliance Dates for Facilities Located in NOX Emissions Control Areas for Which Presumptive RACT is Defined.
Standard	Emissions Control Area	Source Threshold	Notification Date	Demonstration Date	Compliance Date
1997 (0.08 ppm)	Northern Virginia	≥ 100 tpy	March 1, 2007	June 1, 2007	April 1, 2009
2008 (0.075 ppm)	Northern Virginia	≥ 100 tpy	February 1, 2016	February 1, 2016	January 1, 2017

F. Nothing in this article shall exempt any facility subject to the provisions of 9VAC5-40-7410 from being subject to the provisions of this section.
