Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 2 - AIR USE APPROVAL › Section R. 336.1290 - Permit to install exemptions; emission units with limited emissions

Current through Vol. 24-12, July 15, 2024
Rule 290.
(1) This
				rule does not apply if prohibited by
				R
				336.1278 and unless the requirements of
				R
				336.1278a have been met.
(2) The requirement of
				R
				336.1201(1) to obtain a permit to
				install does not apply to any of the emission units listed in subdivision (a)
				of this subrule, if the conditions listed in subdivisions (b), (c), (d), and
				(e) of this subrule are met. Notwithstanding the definition in
				R
				336.1121(a), for the purpose of this
				rule, uncontrolled emissions are the emissions from an emission unit based on
				actual operation, not taking into account any emission control equipment.
				Controlled emissions are the emissions from an emission unit based on actual
				operation, taking into account the control equipment.
(a) An emission unit which meets any of the
				following criteria:
(i) Any emission unit that
				emits only noncarcinogenic volatile organic compounds or noncarcinogenic
				materials that are listed in
				R
				336.1122(f) as not contributing
				appreciably to the formation of ozone, if the total uncontrolled or controlled
				emissions of air contaminants are not more than 1,000 or 500 pounds per month,
				respectively.
(ii) Any emission
				unit for which the CO2 equivalent emissions are not more
				than 6,250 tons per months, the uncontrolled or controlled emissions of all
				other air contaminants are not more than 1,000 or 500 pounds per month,
				respectively, and all of the following criteria are met:
(A) For toxic air contaminants, excluding
				noncarcinogenic volatile organic compounds and noncarcinogenic materials that
				are listed in
				R
				336.1122(f) as not contributing
				appreciably to the formation of ozone, with initial threshold screening levels
				greater than or equal to 0.04 micrograms per cubic meter and less than 2.0
				micrograms per cubic meter, the total uncontrolled or controlled emissions
				shall not exceed 20 or 10 pounds per month, respectively.
(B) For toxic air contaminants with initial
				risk screening levels greater than or equal to 0.04 micrograms per cubic meter,
				the total uncontrolled or controlled emissions shall not exceed 20 or 10 pounds
				per month, respectively.
(C) The
				emission unit shall not emit any toxic air contaminants, excluding
				noncarcinogenic volatile organic compounds and noncarcinogenic materials that
				are listed in
				R
				336.1122(f) as not contributing
				appreciably to the formation of ozone, with an initial threshold screening
				level or initial risk screening level less than 0.04 micrograms per cubic
				meter.
(D) For total mercury, the
				uncontrolled or controlled emissions shall not exceed 0.01 pounds per
				month.
(E) For lead, the
				uncontrolled or controlled emissions shall not exceed 16.7 pounds per
				month.
(iii) Any
				emission unit that emits only particulate air contaminants without initial risk
				screening levels and other air contaminants that are exempted under paragraph
				(i) or (ii) of this subdivision if all of the following provisions are met:
(A) The particulate emissions are controlled
				by an appropriately designed and operated fabric filter collector or an
				equivalent control system that is designed to control particulate matter to a
				concentration of less than or equal to 0.01 pounds of particulate per 1,000
				pounds of exhaust gases and that do not have an exhaust gas flow rate more than
				30,000 actual cubic feet per minute.
(B) The visible emissions from the emission
				unit are not more than 5% opacity in accordance with the methods contained in
				R
				336.1303.
(C) The initial threshold screening level for
				each particulate toxic air contaminant, excluding nuisance particulate, is more
				than 2.0 micrograms per cubic meter.
