Vol. 25 Iss. 19 (Final Regulation) 9VAC5-30, Ambient Air Quality Standards May 25, 2009
REGISTRAR'S NOTICE: The State Air Pollution Control Board is claiming an exemption from the Administrative Process Act in accordance with § 2.2-4006 A 4 c of the Code of Virginia, which excludes regulations that are necessary to meet the requirements of federal law or regulations, provided such regulations do not differ materially from those required by federal law or regulation. The State Air Pollution Control Board will receive, consider and respond to petitions by any interested person at any time with respect to reconsideration or revision.
9VAC5-30. Ambient Air Quality Standards (amending 9VAC5-30-15, 9VAC5-30-80).
Statutory Authority: § 10.1-1308 of the Code of Virginia; §§ 108, 109 and 302 of the Clean Air Act; 40 CFR Parts 50, 53 and 58.
Agency Contact: Karen G. Sabasteanski, Policy Analyst, Department of Environmental Quality, 629 East Main Street, P.O. Box 1105, Richmond, VA 23218, telephone (804) 698-4426, FAX (804) 698-4510, or email karen.sabasteanski@deq.virginia.gov.
9VAC5-30 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 lead was revised to add a new standard of 0.15 parts per million (ppm).

Copies of the document identified in subdivision E 2 a (1) of this subdivision, and Volume I and Supplements A through C of the document identified in subdivision E 2 a (2) of this subdivision, may be obtained from: U.S. Department of Commerce, National Technical Information Service, 5285 Port Royal Road, Springfield, Virginia 22161; phone 1-800-553-6847. Copies of Supplements D and E of the document identified in subdivision E 2 a (2) may be obtained online from EPA's Technology Transfer Network at http://www.epa.gov/ttn/chief/ap42/index.html http://www.epa.gov/ttn/index.html.
All measurements of air quality that are expressed as mass per unit volume (e.g., micrograms per cubic meter) other than for the particulate matter (PM2.5) standards contained in 9VAC5-30-65 and 9VAC5-30-66 and lead standards contained in 9VAC5-30-80 shall be corrected to a reference temperature of 25°C and a reference pressure of 760 millimeters of mercury (1,013.2 millibars). Measurements of PM2.5 for purposes of comparison to the standards contained in 9VAC5-30-65 and 9VAC5-30-66 and of lead for purposes of comparison to the standards contained in 9VAC5-30-80 shall be reported based on actual ambient air volume measured at the actual ambient temperature and pressure at the monitoring site during the measurement period.
A. The primary and secondary ambient air quality standard for lead and its compounds is 1.5 micrograms per cubic meter, maximum arithmetic mean averaged over a calendar quarter, measured as elemental lead by a reference method based on Appendix G of 40 CFR Part 50, or by an equivalent method.
B. Lead and its compounds shall be measured as elemental lead by the reference method based on Appendix G of 40 CFR Part 50, or other method designated as such, or by an equivalent method. The standards set forth in subsection A of this section shall remain applicable to all areas notwithstanding the ambient air quality standard in subsection C of this section. The lead standard set forth in subsection A of this section shall no longer apply to an area one year after the effective date of the designation of that area, pursuant to § 107 of the federal Clean Air Act, for the lead ambient air quality standard set forth in subsection C of this section.
C. The primary and secondary ambient air quality standard for lead and its compounds is 0.15 micrograms per cubic meter, maximum arithmetic mean averaged over a three-month period, measured as lead either by (i) a reference method based on Appendix G of 40 CFR Part 50 and designated in accordance with 40 CFR Part 53; or (ii) an equivalent method designated in accordance with 40 CFR Part 53. The primary and secondary ambient air quality standards for lead are met when the maximum arithmetic three-month mean concentration for a three-year period, as determined in accordance with Appendix R of 40 CFR Part 50, is less than or equal to 0.15 micrograms per cubic meter.
