(B) be temporary.

(2) A source or modification shall be exempt from the requirements of this SECTION with respect to monitoring for a particular pollutant if either of the following apply:

Indiana has no Class I or Class III areas; however, should some areas of the state be classified as Class I or III, the PSD increments pursuant to 40 CFR Part 52.21* shall apply. New permits issued after January 1, 1995, shall use PM₁₀ as the indicator for particulate matter. The allowable increments are as follows:


Maximum Allowable Increments
Pollutants				Allowable Increments (Micrograms per Cubic Meter, μg/m³ Limits)
	(A) Particulate matter:
		(PM₁₀):

(3) When an applicant proposes to construct a major stationary source or major modification in an area designated as attainment or unclassified and the increments listed in subdivision (1) have been consumed, the increased emissions from the source or modification may be permitted to be offset by reducing emissions in the affected areas by an equal amount of the pollutant for which the area was designated as attainment or unclassified.

(4) The following pollutant concentrations shall be excluded when determining compliance with a maximum allowable increase:

(A) Concentrations attributable to the increase in emissions from sources that have converted from the use of petroleum products or natural gas, or both, by reason of an order in effect under Sections 2(a) and 2(b) of the Energy Supply and Environmental Coordination Act of 1974 over the emissions from the sources before the effective date of the order.

(B) Concentrations attributable to the increase in emissions from sources that have converted from using natural gas by reason of a natural gas curtailment plan in effect pursuant to the Federal Power Act over the emissions from the sources before the effective date of the plan.

(C) Concentrations of particulate matter attributable to the increase in emissions from construction or other temporary emission-related activities of new or modified sources.

(D) Concentrations attributable to the temporary increase in emissions of sulfur dioxide, particulate matter, or nitrogen oxides from stationary sources that are affected by state implementation plan revisions approved by U.S. EPA are excluded provided the following criteria is met:

(i) The exclusion shall not exceed two (2) years in duration unless a longer time is approved by the commissioner and the U.S. EPA.

(ii) The exclusion is not renewable.

(iii) The exclusion shall allow no emissions increase that would impact a Class I area or an area where an applicable increment is known to be violated, or cause or contribute to a violation of an ambient air quality standard as designated in 326 IAC 1-3.

(iv) An emission limitation shall be in effect at the end of the time period specified in accordance with item (i) that will ensure that the emissions levels will not exceed those levels occurring from such source before the exclusion was granted.

(5) No exclusion of a concentration under subdivision (4)(A) and (4)(B) shall apply more than five (5) years after the date the exclusion is granted under this rule. If both an order and plan are applicable, no exclusion shall apply more than five (5) years after the latter of the effective dates of the order or the plan.

SECTION 11. (a) This SECTION supersedes 326 IAC 2-2-14(e).

(b) The owner or operator of a proposed major stationary source or major modification may demonstrate to the federal land manager that the emissions from the source or modification would have no adverse impact on the air quality related values of any Class I areas, including visibility, notwithstanding that the change in air quality resulting from emissions from the major stationary source or major modification would cause or contribute to concentrations that would exceed the maximum allowable increases for a Class I area. If the federal land manager concurs with the demonstration and the federal land manager so certifies, the department may issue the permit provided that the applicable requirements of this SECTION are otherwise met, to issue the permit with emission limitations as may be necessary to assure that emissions of sulfur dioxide, particulate matter, and nitrogen oxides shall not exceed the following maximum allowable increases over minor source baseline concentration for such pollutants:


Maximum Allowable Increase
Pollutant		(Micrograms Per Cubic Meter)
