Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 19 - NEW SOURCE REVIEW FOR MAJOR SOURCES IMPACTING NONATTAINMENT AREAS › Section R. 336.2907 - Actuals plant wide applicability limits or PALs

Current through Vol. 24-12, July 15, 2024
Rule 1907.
(1) The
				following definitions apply to the use of actuals PALs. If a term is not
				defined in these paragraphs, then it shall have the meaning given in
				R
				336.2901:
(a)
				"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.
(b) "Allowable emissions" means allowable
				emissions as defined in
				R
				336.1101(k), except this definition
				is modified in the following manner:
(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
				336.2901(z), except that the words
				"or enforceable as a practical matter" shall be added after "legally
				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.
(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. For example, in accordance with the definition
				of major stationary source in section 182(c) of the clean air act, an emissions
				unit is a major emissions unit for volatile organic compounds if the emissions
				unit is located in a serious ozone nonattainment area and it emits or has the
				potential to emit 50 or more tons of volatile organic compounds per
				year.
(e) "Plant wide
				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"
				generally 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
				R 336.2901(s) and
				(v), the definitions for major modification
				and net emissions increase, 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.
(i) "PAL permit" means the permit to install
				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 for that PAL
				pollutant, but less than the amount that would qualify the unit as a major
				emissions unit.
