R 336.1973 Standards for existing large municipal waste combustors.
Cite as Mich. Admin. Code R 336.1973
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:

(6) To comply with the nitrogen oxide emission limit in subrule (5) of this rule, owners or
operators of a LMWC may average nitrogen oxide emissions as stated in 40 CFR
§60.33b(d)(1)(i) to (v), adopted by reference in R 336.1902.
(7) Owners and operators of LMWCs shall comply with the following sections of 40 CFR
Part 60, Subparts Cb and Eb, adopted by reference in R 336.1902:
(a) Definitions in 40 C.F.R. §60.31b and §60.51b.
(b) Operating practices in 40 C.F.R. §60.53b(b) and (c).
(c) Compliance and performance testing in 40 C.F.R. §60.58b, except as provided in
§60.24(b)(2), and LMWC with a dioxin/furan emission level less than or equal to
15 nanograms per dry cubic meter total mass, corrected to 7 percent oxygen, may use the
alternative performance testing schedule for dioxins/furans specified in 40 C.F.R.
§60.58b(g)(5)(iii).
(d) Compliance dates in 40 C.F.R. §60.39b(h).
(e) Recordkeeping and reporting requirements in 40 C.F.R. §60.59b, except those in
§60.59b(a), (b)(5), and (d)(11).
(f) Operator training and certification requirements listed in 40 C.F.R. §60.54b, submitted
within 12 months after state plan approval according to 40 C.F.R. §60.59b(j) if applicable.
(8) For the purposes of this rule, the terms “administrator” and “EPA” as used in 40 C.F.R.
Part 60 and Subparts Cb and Eb, mean the department, except in the authorities retained by
the U.S. EPA in 40 C.F.R. §60.30b(b).
