Section
581 establishes the allowable
degree of deterioration for the areas within the State that have air quality
better than the ambient standards. (3-28-23)
01.
Incorporated Federal Program
Requirements - Class I, II and III Areas. Class I, II, and III area PSD
increment requirements contained in
40 CFR
52.21(c) are incorporated by
reference in Section 107. These
CFR sections have been codified in the electronic CFR at
www.ecfr.gov. (3-28-23)
02.
Exceedances. For any period
other than an annual period, the applicable maximum allowable increase may be
exceeded during one (1) such period per year at any one (1) location.
(3-28-23)
03.
Exclusions. The following concentrations will be excluded in
determining compliance with the maximum allowable increases: (3-28-23)
a. Concentrations attributable to the
increase in emissions from facilities that have converted from the use of
petroleum products, natural gas, or both by reason of an order in effect under
the Energy Supply and Environmental Coordination Act of 1974 (or any
superseding legislation) or by reason of a natural gas curtailment plan in
effect pursuant to the Federal Power Act, over the emissions from such
facilities before the effective date of such order or plan; this does not apply
more than five (5) years after the effective date of such order or plan;
(3-28-23)
b. Concentrations of
PM-10 attributable to the increase in emissions from construction or other
temporary emission-related activities of new or modified facilities;
(3-28-23)
c. The increase in
concentrations attributable to new facilities outside the United States over
the concentrations attributable to existing facilities which are included in
the baseline concentration; and (3-28-23)
d. Concentrations attributable to the
temporary increase in emissions of sulfur dioxide, nitrogen dioxide, or
particulate matter from facilities that are affected by a revision to the SIP
approved by EPA; this exclusion may not exceed two (2) years unless a longer
time is approved by EPA, is not renewable, and applies only to revisions that:
(3-28-23)
i. Would not affect the applicable
pollutant concentrations in a Class I area or an area where an applicable
increment is known to be violated and would not cause or contribute to a
violation of an ambient air quality standard; and (3-28-23)
ii. Require limitations to be in effect at
the end of the approved time period that would ensure that the emissions from
facilities affected by the revision would not exceed those concentrations
occurring before the revision was approved.
