Indiana Administrative Code
Title 326 - AIR POLLUTION CONTROL DIVISION
Article 2 - PERMIT REVIEW RULES
Rule 2.4 - Actuals Plantwide Applicability Limitations in Attainment Areas
Section 2.4-2 - Definitions

(a) The definitions in this section apply throughout this rule. A term that is not defined in this section shall have the meaning set forth in 326 IAC 2-2-1 or in the CAA.

(b) "Actuals PAL", for a major stationary source, means a PAL based on the baseline actual emissions of all emissions units at the source that emit or have the potential to emit the PAL pollutant.

(c) "Allowable emissions", for the purposes of this rule, means the following:

(d) "Major emissions unit" means any emissions unit that emits or has the potential to emit one hundred (100) tons per year or more of the PAL pollutant in an attainment area.

(e) "PAL effective date" generally means the date of issuance of the PAL permit. However, the PAL effective date for an increased PAL under section 11 of this rule is the date any emissions unit that is part of the PAL major modification becomes operational and begins to emit the PAL pollutant.

(f) "PAL effective period" means the period beginning with the PAL effective date and ending ten (10) years later.

(g) "PAL major modification" means, notwithstanding the definitions for major modification and net emissions increase in 326 IAC 2-2-1, any physical change in or change in the method of operation of the PAL source that causes it to emit the PAL pollutant at a level equal to or greater than the PAL.

(h) "PAL permit" means the permit issued by the department that contains PAL provisions for a major stationary source.

(i) "PAL pollutant" means the pollutant for which a PAL is established at a major stationary source.

(j) "Plantwide applicability limitation" or "PAL" means an emission limitation expressed in tons per year, for a pollutant at a major stationary source, that is enforceable as a practical matter and established source-wide in accordance with this rule. For the purposes of this rule, a PAL is an actuals PAL.

(k) "Significant emissions unit" means an emissions unit that emits or has the potential to emit a PAL pollutant in an amount that is equal to or greater than the significant level as defined in 326 IAC 2-2-1(ww) or in the CAA, whichever is lower, for that PAL pollutant, but less than the amount that would qualify the unit as a major emissions unit as defined in subsection (d).

(l) "Small emissions unit" means an emissions unit that emits or has the potential to emit the PAL pollutant in an amount less than the significant level for that PAL pollutant as defined in 326 IAC 2-2-1(ww) or in the CAA, whichever is lower.
