Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 18 - PREVENTION OF SIGNIFICANT DETERIORATION OF AIR QUALITY › Section R. 336.2823 - Actuals plantwide applicability limits (PALs)

Current through Vol. 24-12, July 15, 2024
Rule 1823.
(1) The
				following definitions apply to the use of actuals PALs consistent with this
				rule. If a term is not defined in these paragraphs, it shall have the meaning
				given in
				R
				336.2801 or
				R
				336.1101 to
				R
				336.1127.
(a)
				"Actuals PAL for a major stationary source" means a PAL based on the baseline
				actual emissions of all emissions units at the major source that emit or have
				the potential to emit the PAL pollutant.
(b) "Allowable emissions" means allowable
				emissions as defined in
				R
				336.2801, except as this definition is modified by the
				following:
(i) The allowable emissions for any
				emissions unit shall be calculated considering any emission limitations that
				are enforceable as a practical matter on the emissions unit's potential to
				emit.
(ii) An emissions unit's
				potential to emit shall be determined using the definition in
				R
				336.2801, except that the words "or enforceable as a
				practical matter" should be added after "federally enforceable."
(c) "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
				R
				336.2801 or in the clean air act, whichever is
				lower.
(d) "Major emissions unit"
				means either of the following:
(i) Any
				emissions unit that emits or has the potential to emit 100 tons per year or
				more of the PAL pollutant in an attainment area.
(ii) Any emissions unit that emits or has the
				potential to emit the PAL pollutant in an amount that is equal to or greater
				than the major source threshold for the PAL pollutant as defined by the clean
				air act for nonattainment areas.
(e) "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.
(f) "PAL effective date" means the date of
				issuance of the PAL permit. However, the PAL effective date for an increased
				PAL is the date any emissions unit that is part of the PAL major modification
				becomes operational and begins to emit the PAL pollutant.
(g) "PAL effective period" means the period
				beginning with the PAL effective date and ending 10 years later.
(h) "PAL major modification" means,
				notwithstanding the definitions for major modification and net emissions
				increase, any physical change in or change in the method of operation of the
				PAL major source that causes it to emit the PAL pollutant at a level equal to
				or greater than the PAL.
(i) "PAL
				permit" means the permit to install issued under
				R
				336.1201(1)(a) or
				R 336.1214a that establishes a PAL
				for a major stationary source.
(j)
				"PAL pollutant" means the pollutant for which a PAL is established at a major
				stationary source.
(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
				R
				336.2801 or in the clean air act, whichever is lower,
				for that PAL pollutant, but less than the amount that would qualify the unit as
				a major emissions unit.
