AMBIENT AIR QUALITY STANDARDS.

9VAC5-30-55. Ozone (8-hour, 0.08 ppm).

A. The primary and secondary ambient air quality standard is 0.08 parts per 

million, daily maximum 8-hour average.

B. Ozone shall be measured by the reference method described in Appendix D 

of 40 CFR Part 50, other method designated as such, or by an equivalent method.

C. The 8-hour primary and secondary ozone ambient air quality standards are 

met at an ambient air quality monitoring site when the average of the annual fourthhighest daily maximum 8-hour average ozone concentration is less than or equal to 

0.08 ppm, as determined in accordance with Appendix I to 40 CFR Part 50.

9VAC5-30-56. Ozone (8-hour, 0.075 ppm).

A. The primary and secondary ambient air quality standard is 0.075 parts per 

million, daily maximum 8-hour average.

B. Ozone shall be measured by the reference method described in Appendix D 

of 40 CFR Part 50, other method designated as such, or by an equivalent method.

C. The 8-hour primary and secondary ozone ambient air quality standards are 

met at an ambient air quality monitoring site when the 3-year average of the annual 

fourth-highest daily maximum 8-hour average ozone concentration is less than or equal 

to 0.075 ppm, as determined in accordance with Appendix P to 40 CFR Part 50.

9VAC5-30-65. Particulate matter (PM2.5).

A. The primary and secondary ambient air quality standards for particulate 

matter are:

1. 15.0 micrograms per cubic meter -- annual arithmetic mean 

concentration.

2. 65 micrograms per cubic meter -- 24-hour average concentration.

B. Particulate matter shall be measured in the ambient air as PM2.5 (particles 

with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers) by the 

reference method based on Appendix L of 40 CFR Part 50, or other method designated 

as such, or by equivalent method.

REGULATIONS FOR THE CONTROL AND ABATEMENT OF AIR POLLUTION (9VAC5-20 AND 30)

C. The annual primary and secondary PM2.5 standards are met when the annual 

arithmetic mean concentration, as determined in accordance with Appendix N of 40 

CFR Part 50, is less than or equal to 15.0 micrograms per cubic meter.

D. The 24-hour primary and secondary PM2.5 standards are met when the 98th 

percentile 24-hour concentration, as determined in accordance with Appendix N of 40 

CFR Part 50, is less than or equal to 65 micrograms per cubic meter.

E. The PM2.5 standards set forth in this section were established by EPA on July 

18, 1997 (62 FR 38856 38652) and became effective on September 8, 2004 by 

adoption by the board. The PM2.5 standards set forth in this section shall continue to 

apply only for purposes of the following:

1. Control strategy implementation plan revisions, maintenance plans, and 

associated emissions budgets relative to the PM2.5 standards in this section.

2. Designation of nonattainment areas and maintenance areas relative to 

the PM2.5 standards in this section.

Nothing in this section shall prevent the redesignation of any nonattainment area to 

attainment at any time.
