11 Section 165(a)(3) of the CAA requires that proposed new and modified major stationary

12 sources seeking a permit must demonstrate that their additional pollutant emissions will not

13 cause or contribute to a violation of any NAAQS or increment. This requirement is implemented

14 in 40 CFR 52.21(k)(1) (and at 40 CFR 51.166(k)(1) with slightly different wording) as follows:

15 (k) Source impact analysis—(1) Required demonstration. The owner or operator of the

16 proposed source or modification shall demonstrate that allowable emission increases

17 from the proposed source or modification, in conjunction with all other applicable

18 emissions increases or reductions (including secondary emissions), would not cause or

19 contribute to air pollution in violation of:

20 (i) Any national ambient air quality standard in any air quality control region; or

21 (ii) Any applicable maximum allowable increase over the baseline concentration in

22 any area.

24 The EPA has historically supported the use of SILs to help determine the scope of the

25 required air quality analysis that must be carried out to demonstrate that the source’s emissions
