The following demonstrations are required by a nonattainment review.
a) The project will comply with the lowest achievable emission rate (LAER).
LAER is defined as the more stringent of 1) the most stringent emissions limitation
imposed by any state on a similar source unless proven not to be achievable, or 2) the
most stringent emissions limitation achieved in practice by a similar source.
b) The owner or operator of the proposed source must demonstrate that all
major stationary sources owned or operated by such person (or by an entity controlling,
controlled by, or under common control with such person) in the state are subject to
emission limitations and are in compliance, or on a schedule for compliance, with all
applicable Federal and state emission limitations and standards.
c) The owner or operator of the proposed source must obtain sufficient
emission reductions to offset the impacts within the nonattainment area of the source's
emissions of the nonattainment pollutant. Air quality modeling must predict the
emission offsets will cause a positive net air quality benefit in that portion of the
nonattainment area affected by emissions from the proposed source.
d) The most stringent emissions limitation imposed by any state on a
similar source unless proven not be achievable.
e) The most stringent emissions limitation achieved in practice by a
similar source.
