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.
