WAC 173-400-113   Requirements for new sources in attainment or unclassifiable areas.  The permitting authority that is reviewing an application to establish a new source or modification in an attainment or unclassifiable area shall issue an order of approval if it determines that the proposed project satisfies each of the following requirements:

     (1) The proposed new source or modification will comply with all applicable new source performance standards, national emission standards for hazardous air pollutants, national emission standards for hazardous air pollutants for source categories, emission standards adopted under chapter 70.94 RCW and, for sources regulated by an authority, the applicable emission standards of that authority.

     (2) The proposed new source or modification will employ BACT for all pollutants not previously emitted or whose emissions would increase as a result of the new source or modification.

     (3) Allowable emissions from the proposed new source or modification will not delay the attainment date for an area not in attainment nor cause or contribute to a violation of any ambient air quality standard. This requirement will be considered to be met if the projected impact of the allowable emissions from the proposed new source or the projected impact of the increase in allowable emissions from the proposed modification at any location within a nonattainment area does not exceed the following levels for the pollutants for which the area has been designated nonattainment:

Pollutant	Annual Average	24-Hour Average	8-Hour Average	3-Hour Average	1-Hour Average
CO-	-		0.5 mg/m3	-	2 mg/m3
SO2	1.0 µg/m3	5 µg/m3	-	25 µg/m3	30 µg/m3
PM10	1.0 µg/m3	5 µg/m3	-	-	-
NO2	1.0 µg/m3	-	-	-	-

     An offsetting emission reduction may be used to satisfy some or all of the requirements of this subsection.

     (4) If the proposed new source is a major stationary source or the proposed modification is a major modification, it meets all applicable requirements of WAC 173-400-720 through 173-400-750.

     (5) If the proposed new source or the proposed modification will emit any toxic air pollutants regulated under chapter 173-460 WAC, the source meets all applicable requirements of that program.

     (6) If the proposed new source is a major stationary source or the proposed modification is a major modification, the project meets the special protection requirements for federal Class I areas of WAC 173-400-117.
