Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 9 - EMISSION LIMITATIONS AND PROHIBITIONS -MISCELLANEOUS › Section R. 336.1973 - Standards for existing large municipal waste combustors

Current through Vol. 24-12, July 15, 2024
Rule 973
(1) This
				rule applies to all existing large municipal waste combustors (LMWC) and air
				curtain incinerators that have a combustion capacity greater than 250 tons per
				day of municipal solid waste, commenced construction by September 20,
				1994.
(2) LMWCs defined under
				40 C.F.R. §
										60.32b(b),
				(d) to (i), and (l) to (n), adopted by
				reference in
				R
				336.1902, are exempt from this rule if the owner or
				operator notifies the department that the LMWC qualifies for the exemption and
				any applicable requirements listed in
				40 C.F.R. §
										60.32b are followed.
(3) A LMWC remains subject to this rule if
				any physical or operational changes are made primarily for the purpose of
				complying with this rule. Those changes cannot be considered in determining
				modification or reconstruction under 40 C.F.R. Part 60, subparts Ea or
				Eb.
(4) Owners and operators of
				LMWCs shall submit documentation to the department, within 90 days of state
				plan approval, that the unit is operating under a fully trained LMWC operator
				required under
				40
				C.F.R. §
										60.35b, adopted by reference in
				R
				336.1902, and that the LMWC is in compliance with the
				emission and operating limits in subrules (5) and (6) of this rule.
(5) Owners and operators of LMWCs shall
				comply with all of the following emission limits in 40 C.F.R. Part 60, Subparts
				Cb and Eb, adopted by reference in
				R
				336.1902:
(a) Carbon
				monoxide limits in Table 3 in Subpart Cb
(b) Fugitive ash emission limits in
				40
				C.F.R. §
											60.55b
(c) Nitrogen oxide limits in Tables 1 and 2
				in Subpart Cb
(d) Other emission
				limits listed in Table 973:
