Section 326IAC2-3-1. Definitions

   (a) The definitions in this section apply throughout this rule.

  (b) "Actual emissions" means the actual rate of emissions of a regulated NSR pollutant from an emissions unit as determined in accordance with the following:

(1) In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a consecutive twenty-four (24) month period that:

(A) precedes the particular date; and

(B) is representative of normal source operation.

The commissioner shall allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

(2) The commissioner may presume that source-specific allowable emissions for the unit are equivalent to the actual emissions of the unit.

(3) For any emissions unit that has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date.

(4) The term shall not apply for calculating a significant emissions increase under section 2(c) of this rule or for establishing a PAL under 326 IAC 2-3.4. Instead, subsections (d) and (kk) shall apply for those purposes.

  (c) "Allowable emissions" means the emissions rate of a source calculated using the maximum rated capacity of the source unless a source is subject to enforceable permit limits that restrict the operating rate or hours of operation, or both, and the most stringent of the following:

(1) The applicable standards as set forth in 40 CFR Part 60, New Source Performance Standards (NSPS)*, and 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAPS)*.

(2) The emissions limitation imposed by any rule in this title, including those with a future compliance date.

(3) The emissions rate specified as an enforceable permit condition, including those with a future compliance date.

  (d) "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined as follows:

(1) For any existing electric utility steam generating unit, the term means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by the owner or operator within the five (5) year period immediately preceding when the owner or operator begins actual construction of the project. The commissioner may allow the use of a different time period upon a determination that it is more representative of normal source operation. The baseline actual emissions shall be determined in accordance with the following:

(A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions to the extent they are affected by the project.

(B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive twenty-four (24) month period.

(C) For a regulated NSR pollutant, when a project involves multiple emissions units, only one (1) consecutive twenty-four (24) month period may be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for each regulated NSR pollutant.

(D) The average rate shall not be based on any consecutive twenty-four (24) month period for which there is inadequate information available for determining annual emissions, in tons per year, and for adjusting this amount if required by clause (B).

(2) For an existing emissions unit, other than an electric utility steam generating unit, the term means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by the owner or operator within the ten (10) year period immediately preceding either the date the owner or operator begins actual construction of the project or the date a complete permit application is received by the department for a permit required under 326 IAC 2-3, except that the ten (10) year period shall not include any period earlier than November 15, 1990. The baseline actual emissions shall be determined in accordance with the following:

(A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions and to the extent they are affected by the project.

(B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive twenty-four (24) month period.

(C) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply had the major stationary source been required to comply with the limitations during the consecutive twenty-four (24) month period. However, if an emission limitation is part of a maximum achievable control technology standard that the U.S. EPA proposed or promulgated under 40 CFR Part 63*, the baseline actual emissions need only be adjusted if the state has applied the emissions reduction to an attainment demonstration or maintenance plan consistent with the requirements of section 3(b)(12) of this rule.

(D) For a regulated NSR pollutant, when a project involves multiple emissions units, only one (1) consecutive twenty-four (24) month period must be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for each regulated NSR pollutant.

(E) The average rate shall not be based on any consecutive twenty-four (24) month period for which there is inadequate information available for determining annual emissions, in tons per year, and for adjusting this amount if required by clauses (B) and (C).

(3) For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of the unit shall equal zero (0) and thereafter, for all other purposes, shall equal the unit's potential to emit.

(4) For a PAL for a major stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in subdivision (1), for other existing emissions units in accordance with the procedures contained in subdivision (2), and for a new emissions unit in accordance with the procedures contained in subdivision (3).

  (e) "Begin actual construction" means, in general, initiation of physical on-site construction activities on an emissions unit that are of a permanent nature. These activities include, but are not limited to, the following:

(1) Installation of building supports and foundations.

(2) Laying underground pipework.

(3) Construction of permanent storage structures.

With respect to a change in method of operations, the term refers to those on-site activities, other than preparatory activities, that mark the initiation of the change.

  (f) "Best available control technology" or "BACT" means an emissions limitation, including a visible emission standard, based on the maximum degree of reduction for each regulated NSR pollutant that would be emitted from any proposed major stationary source or major modification that the commissioner, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for the source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of the pollutant. In no event shall application of BACT result in emissions of any pollutant that would exceed the emissions allowed by any applicable standard under 40 CFR Part 60* or 40 CFR Part 61*. If the commissioner determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard, or combination thereof may be prescribed instead to satisfy the requirement for the application of BACT. The standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of the design, equipment, work practice, or operation and shall provide for compliance by means that achieve equivalent results.

  (g) "Building, structure, facility, or installation" means all of the pollutant-emitting activities that belong to the same industrial grouping, are located on one (1) or more contiguous or adjacent properties, and are under the control of the same person or persons under common control. Pollutant-emitting activities shall be considered as part of the same industrial grouping if they belong to the same major group, that is, those that have the same first two (2) digit code, as described in the Standard Industrial Classification Manual, 1972, as amended by the 1977 supplement, U.S. Government Printing Office*.

  (h) "Clean coal technology" means any technology, including technologies applied at the precombustion, combustion, or postcombustion stage, at a new or existing facility that will achieve significant reductions in air emissions of sulfur dioxide or nitrogen oxides associated with the utilization of coal in the generation of electricity or process steam that was not in widespread use as of November 15, 1990.

  (i) "Clean coal technology demonstration project" means a project using funds appropriated under the heading "Department of Energy-Clean Coal Technology", up to a total amount of two billion five hundred million dollars ($2,500,000,000) for commercial demonstration of clean coal technology, or similar projects funded through appropriations for the U.S. EPA. The federal contribution for a qualifying project shall be at least twenty percent (20%) of the total cost of the demonstration project.

(1) begun, or caused to begin, a continuous program of actual on-site construction of the source to be completed within a reasonable time; or

(2) entered into binding agreements or contractual obligations, which cannot be canceled or modified without substantial loss to the owner or operator, to undertake a program of actual construction of the source to be completed within a reasonable time.

  (k) "Complete", in reference to an application for a permit, means that the application contains all of the information necessary for processing the application.

(2) requirements within the SIP; and

(3) any permit requirements established pursuant to 40 CFR Part 52.21* or under regulations approved pursuant to 40 CFR Part 51, Subpart I*, including operating permits issued under an EPA-approved program that is incorporated into the SIP and expressly requires adherence to any permit issued under the program.

  (u) "Fugitive emissions" means those emissions that could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.

  (v) "Incidental emissions reductions" means the reductions in emissions of a pollutant achieved as an indirect result of complying with another rule for another pollutant.

  (w) "Internal offset" means to use net emissions decreases from within the source to compensate for an increase in emissions.

(2) Achieved in practice by the class or category of stationary source. This limitation, when applied to a modification, means the LAER for the new or modified emissions unit within the stationary source. In no event shall the application of the LAER allow a proposed new or modified stationary source to emit any pollutant in excess of the amount allowable under applicable new source standards of performance.

  (y) "Major modification" means any physical change in, or change in the method of operation of, a major stationary source that would result in a significant emissions increase and a significant net emissions increase of a regulated NSR pollutant from the major stationary source or, in an area that is classified as either a serious or severe ozone nonattainment area, an increase in VOC or nitrogen oxides (unless a NO_X waiver is in effect) emissions that is not de minimis.
