Subch. H of ch. NR 666 Note
Note: This subchapter is similar to federal regulations contained in
40 CFR part 266 subpart H, revised as of July 1, 2003.
NR 666.100(1)(1)
The regulations of this subchapter apply to hazardous waste burned or processed in a boiler or industrial furnace (as defined in s.
NR 660.10) irrespective of the purpose of burning or processing, except as provided by subs.
(2),
(3),
(4),
(7) and
(8). In this subchapter, the term “burn" means burning for energy recovery or destruction, or processing for materials recovery or as an ingredient. The emissions standards of ss.
NR 666.104,
666.105,
666.106 and
666.107 apply to facilities operating under an interim license or under a license as specified in ss.
NR 666.102 and
666.103.
NR 666.100(2)(a)(a) Except as provided by pars.
(b),
(c), and
(d), the standards of this subchapter do not apply to a new hazardous waste boiler or industrial furnace unit that becomes subject to hazardous waste license requirements after October 12, 2005; or no longer apply when an affected source demonstrates compliance with the maximum achievable control technology (MACT) requirements of
40 CFR part 63, subpart EEE, by conducting a comprehensive performance test and submitting to the department a notification of compliance under
40 CFR 63.1207(j) and 63.1210(d) documenting compliance with
40 CFR part 63, subpart EEE. Nevertheless, even after this demonstration of compliance with the MACT standards, hazardous waste license conditions that were based on the standards of this chapter shall continue to be in effect until the conditions are removed from the license or the license is terminated or revoked, unless the license expressly provides otherwise.
NR 666.100(2)(b)1.
1. If you elect to comply with s.
NR 670.235 (1) (a) 1. to minimize emissions of toxic compounds from startup, shutdown and malfunction events, s.
NR 666.102 (5) (a) requiring operations in accordance with the operating requirements specified in the license at all times that hazardous waste is in the unit, and s.
NR 666.102 (5) (b) 3. requiring compliance with the emission standards and operating requirements during startup and shutdown if hazardous waste is in the combustion chamber, except for particular hazardous wastes. These provisions apply only during startup, shutdown and malfunction events.
NR 666.100(2)(c)
(c) If an owner or operator of a boiler or hydrochloric acid production furnace that is an area source under
40 CFR 63.2 and the owner or operator elects not to comply with the emission standards under
40 CFR 63.1216,
63.1217, and
63.1218 for particulate matter, semi-volatile and low volatile metals and total chlorine, the owner or operator remains subject to:
NR 666.100(2)(d)
(d) The particulate matter standard of s.
NR 666.105 remains in effect for boilers that elect to comply with the alternative to the particulate matter standard under
40 CFR 63.1216(e) and 63.1217(e).
NR 666.100(3)
(3) The following hazardous wastes and facilities are not subject to regulation under this subchapter:
NR 666.100(3)(a)
(a) Used oil burned for energy recovery that is also a hazardous waste solely because it exhibits a characteristic of hazardous waste identified in subch.
C of ch. NR 661. Such used oil is subject to regulation under ch.
NR 679.
NR 666.100(3)(b)
(b) Gas recovered from hazardous or solid waste landfills when such gas is burned for energy recovery.
NR 666.100(3)(d)

NR 666.100(4)(a)3.
3. Maintain at the facility for at least 3 years records to document compliance with this subsection including limits on levels of toxic organic constituents and Btu value of the waste, and levels of recoverable metals in the hazardous waste compared to normal nonhazardous waste feedstocks.
NR 666.100(4)(b)
(b) A hazardous waste meeting either of the following criteria is not processed solely for metal recovery:
NR 666.100(4)(b)1.
1. The hazardous waste has a total concentration of organic compounds listed in ch.
NR 661 Appendix VIII, exceeding 500 ppm by weight, as-fired, and so is considered to be burned for destruction. The concentration of organic compounds in a waste as-generated may be reduced to the 500 ppm limit by bona fide treatment that removes or destroys organic constituents. Blending for dilution to meet the 500 ppm limit is prohibited and documentation that the waste has not been impermissibly diluted shall be retained in the records required by par.
(a)3. NR 666.100(4)(b)2.
2. The hazardous waste has a heating value of 5,000 Btu/lb or more, as-fired, and so is considered to be burned as fuel. The heating value of a waste as-generated may be reduced to below the 5,000 Btu/lb limit by bona fide treatment that removes or destroys organic constituents. Blending for dilution to meet the 5,000 Btu/lb limit is prohibited and documentation that the waste has not been impermissibly diluted shall be retained in the records required by par.

NR 666 Appendix XI, ch.
NR 666 Appendix XII, or ch.
NR 666 Appendix XIII that contains a total concentration of more than 500 ppm toxic organic compounds listed in ch.
NR 661 Appendix VIII may pose a hazard to human health and the environment when burned in a metal recovery furnace exempt from this subchapter. In that situation, after adequate notice and opportunity for comment, the metal recovery furnace shall become subject to this subchapter when burning that material. In making the hazard determination, the department will consider all of the following factors:
NR 666.100(4)(c)2.b.
b. The level of destruction of toxic organic constituents provided by the furnace.
NR 666.100(4)(c)2.c.
