9VAC5-80-1765. Sources Affecting Federal Class I Areas -- Additional Requirements.

A. The board shall transmit to the administrator a copy of each permit application relating to a major stationary source or major modification and provide notice to the administrator of the following actions related to the consideration of such permit:

1. Notification of the permit application status as provided in 9VAC5-80-1773 A.

2. Notification of the public comment period on the application as provided in 9VAC5-80-1775 F 2.

3. Notification of the final determination on the application and issuance of the permit as provided in 9VAC5-80-1773 D.

4. Notification of any other action deemed appropriate by the board.

B. The board shall provide written notice of any permit application for a proposed major stationary source or major modification, the emissions from which may affect a class I area, to the federal land manager and the federal official charged with direct responsibility for management of any lands within any such area. Such notification shall include a copy of all information relevant to the permit application and shall be given within 30 days of receipt and at least 60 days prior to any public hearing on the application for a permit to construct. Such notification shall include an analysis of the proposed source's anticipated impacts on visibility in the federal class I area. The board shall also provide the federal land manager and such federal officials with a copy of the preliminary determination required under 9VAC5-80-1773 B, and shall make available to them any materials used in making that determination, promptly after the board makes such determination. Finally, the board shall also notify all affected federal land managers within 30 days of receipt of any advance notification of any such permit application.

C. The federal land manager and the federal official charged with direct responsibility for management of such lands have an affirmative responsibility to protect the air quality related values (including visibility) of such lands and to consider, in consultation with the board, whether a proposed source or modification will have an adverse impact on such values.

D. The board shall consider any analysis performed by the federal land manager, provided within 30 days of the notification required by subsection B of this section, that shows that a proposed new major stationary source or major modification may have an adverse impact on visibility in any federal class I area. Where the board finds that such an analysis does not demonstrate to the satisfaction of the board that an adverse impact on visibility will result in the federal class I area, the board shall, in the notice of public hearing on the permit application, either explain this decision or give notice as to where the explanation can be obtained.

E. The federal land manager of any such lands may demonstrate to the board that the emissions from a proposed source or modification would have an adverse impact on the air quality-related values (including visibility) of those lands, notwithstanding that the change in air quality resulting from emissions from such source or modification would not cause or contribute to concentrations that would exceed the maximum allowable increases for a class I area. If the board concurs with such demonstration, then it shall not issue the permit.

F. The owner of a proposed source or modification may demonstrate to the federal land manager that the emissions from such source or modification would have no adverse impact on the air quality related values of any such lands (including visibility), notwithstanding that the change in air quality resulting from emissions from such source or modification would cause or contribute to concentrations that would exceed the maximum allowable increases for a class I area. If the federal land manager concurs with such demonstration and so certifies, the board may, provided that the applicable requirements of this article are otherwise met, issue the permit with such emission limitations as may be necessary to assure that emissions of sulfur dioxide, PM2.5, PM10, and nitrogen oxides would not exceed the following maximum allowable increases over minor source baseline concentration for such pollutants:

MAXIMUM ALLOWABLE INCREASE
(micrograms per cubic meter)

PM2.5:

Annual arithmetic mean

4

24 hour maximum

9

PM10:

Annual arithmetic mean

17

24 hour maximum

30

Sulfur dioxide:

Annual arithmetic mean

20

24-hour maximum

91

Three-hour maximum

325

Nitrogen dioxide:

Annual arithmetic mean

25

G. The owner of a proposed source or modification that cannot be approved under subsection F of this section may demonstrate to the governor that the source or modification cannot be constructed by reason of any maximum allowable increase for sulfur dioxide for a period of 24 hours or less applicable to any class I area and, in the case of federal mandatory class I areas, that a variance under this clause would not adversely affect the air quality related values of the area (including visibility). The governor, after consideration of the federal land manager's recommendation (if any) and subject to the federal land manager's concurrence, may, after notice and public hearing, grant a variance from such maximum allowable increase. If such variance is granted, the board shall issue a permit to such source or modification pursuant to the requirements of subsection I of this section, provided that the applicable requirements of this article are otherwise met.

H. In any case whether the governor recommends a variance in which the federal land manager does not concur, the recommendations of the governor and the federal land manager shall be transmitted to the president. The president may approve the governor's recommendation if he finds that the variance is in the national interest. If the variance is approved, the board shall issue a permit pursuant to the requirements of subsection I of this section, provided that the applicable requirements of this article are otherwise met.

I. In the case of a permit issued pursuant to subsection G or H of this section the source or modification shall comply with such emission limitations as may be necessary to assure that emissions of sulfur dioxide from the source or modification would not (during any day on which the otherwise applicable maximum allowable increases are exceeded) cause or contribute to concentrations that would exceed the following maximum allowable increases over the baseline concentration and to assure that such emissions would not cause or contribute to concentrations which exceed the otherwise applicable maximum allowable increases for periods of exposure of 24 hours or less for more than 18 days, not necessarily consecutive, during any annual period:

MAXIMUM ALLOWABLE INCREASE
(micrograms per cubic meter)

Period of exposure

Low terrain areas

High terrain areas

24-hour maximum

36

62

3-hour maximum

130
