Action 4531
General Information
Action Summary On October 26, 2015 (80 FR 65292), the U.S. Environmental Protection Agency (EPA) revised the ozone national ambient air quality standard (NAAQS) by adding an 8-hour standard at a level of 0.070 parts per million (ppm). The existing 8-hour standard of 0.075 ppm was not revoked. The new primary standard became effective on December 28, 2015. Chapter 30 contains the ambient air quality standards for the specific criteria pollutant standards set out in 40 CFR Part 50. Therefore, this chapter is the action effectively implementing the EPA requirements, and must now be amended accordingly. In addition, a new Appendix U has been added. Appendix U explains the data handling conventions and computations necessary for determining whether the NAAQS for ozone are met at an ambient air quality monitoring site; this appendix is incorporated by reference in 9VAC5-20-21. These regulations must now be amended accordingly in order to properly implement new source permitting review and various ozone implementation and planning programs.
