•  Reduce impacts at majority of receptors; and

•  Impacts less than SIL at all receptors

Offsets

•  1.0:1 for other pollutants, with provision to reduce the ratio if offsets are obtained from priority sources

•  Source plus competing sources since area was designated less than 10% of the NAAQS
