Ambient Air Quality Standards [9 VAC 5 ‑ 30]
This action is exempt from the executive branch review process.
Action:
Ambient Air Quality Standards (Rev. A10)
 
General Information
Action Summary Chapter 30 contains the national ambient air quality standards (NAAQS) for the specific criteria pollutants set out in 40 CFR Part 50. Incorporation of the NAAQS into the state regulations is necessary to provide a legally enforceable means by which the state prepares attainment and maintenance plans, and determines whether a new source will affect the NAAQS. The standard for nitrogen dioxide (NO2) was revised to (i) specify that NO2 is the indicator for nitrogen oxides (NOX), (ii) limit the 53 parts per billion standard to the annual primary standard, (iii) add a new primary 1-hour standard, (iv) specify reference methods, and (v) specify how the different standards are attained.
