Virginia Law

A. Preapplication analysis shall be conducted as follows:

1. Any application for a permit under this article shall contain an analysis of ambient air quality in the area that the major stationary source or major modification would affect for each of the following pollutants:

a. For the source, each pollutant that it would have the potential to emit in a significant amount;

b. For the modification, each pollutant for which it would result in a significant net emissions increase.

2. With respect to any such pollutant for which no ambient air quality standard exists, the analysis shall contain such air quality monitoring data as the department determines is necessary to assess ambient air quality for that pollutant in any area that the emissions of that pollutant would affect.

3. With respect to any such pollutant (other than nonmethane hydrocarbons) for which such a standard does exist, the analysis shall contain continuous air quality monitoring data gathered for purposes of determining whether emissions of that pollutant would cause or contribute to a violation of the standard or any maximum allowable increase.

4. In general, the continuous air quality monitoring data that is required shall have been gathered over a period of at least one year and shall represent at least the year preceding receipt of the application, except that, if the department determines that a complete and adequate analysis can be accomplished with monitoring data gathered over a period shorter than one year (but not to be less than four months), the data that is required shall have been gathered over at least that shorter period.

5. The owner of a proposed stationary source or modification of volatile organic compounds who satisfies all conditions of §IV of Appendix S to 40 CFR Part 51 may provide post-approval monitoring data for ozone in lieu of providing preconstruction data as required under this subsection.

B. The owner of a major stationary source or major modification shall, after construction of the stationary source or modification, conduct such ambient monitoring as the department determines is necessary to determine the effect emissions from the stationary source or modification may have, or are having, on air quality in any area.

C. The owner of a major stationary source or major modification shall meet the requirements of Appendix B to 40 CFR Part 58 during the operation of monitoring stations for purposes of satisfying this section.
