Virginia Administrative Code
Title 9. Environment
Agency 5. State Air Pollution Control Board
Chapter 30. Ambient Air Quality Standards
11/21/2024

9VAC5-30-10. General.

A. The provisions of this chapter, unless specified otherwise, shall apply throughout the Commonwealth of Virginia.

B. Ambient air quality standards are required to assure that ambient concentrations of air pollutants are consistent with established criteria and shall serve as the basis for effective and reasonable management of the air resources of the Commonwealth of Virginia.

C. Primary ambient air quality standards define levels of air quality which, allowing an adequate margin of safety, are necessary to protect the public health. Secondary ambient air quality standards define more stringent levels of air quality which are necessary to protect the public welfare from any known or anticipated adverse effects associated with the presence of air pollutants in the ambient air. At such time as additional pertinent information becomes available with respect to applicable air quality criteria, such information will be considered and the ambient air quality standards will be revised accordingly.

D. The absence of a specific ambient air quality standard shall not preclude action by the board to control pollutants to assure protection, safety, welfare and comfort of the people of the Commonwealth of Virginia.

E. Where applicable, all measurements of air quality shall be corrected to a reference temperature of 77 degrees Fahrenheit and to a reference pressure of 14.7 pounds per square inch absolute.
