Section R. 336.1973 - Standards for existing large municipal waste combustors

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:

Pollutant	Emission Limit
Cadmium in 40 C.F.R. § 60.33b(a)(2)(i)	35 µg/dscm+
Dioxin/furan in 40 C.F.R. § 60.33b(c)	IF electrostatic precipitator, then 35 ng/dscm+ (total mass) IF no electrostatic precipitator, then 30 ng/dscm+ (total mass)
Hydrogen Chloride in 40 C.F.R. § 60.33b(b)(3)	29 ppm per volume OR 5% of the potential hydrogen chloride emission concentration (95% reduction by weight or volume), whichever is less stringent*
Lead in 40 C.F.R. § 60.33b(a)(4)	400 µg/dscm+
Mercury in 40 C.F.R. § 60.33b(a)(3)	50 µg/dscm OR 15% of the potential mercury emission concentration (85% reduction by weight), whichever is less stringent+
Opacity in 40 C.F.R. § 60.33b(a)(1)(iii)	10% (6 minute average)
Particulate Matter in 40 C.F.R. § 60.33b(a)(1)(i)	25 mg/dscm+
Sulfur Dioxide in 40 C.F.R. § 60.33b(b)(3)	29 ppm by volume OR 25% of the potential sulfur dioxide emission concentration (75% reduction by weight or volume), whichever is less stringent*º

º Based on 24-hour daily geometric mean

(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).
