SPECIFIC TYPES OF HAZARDOUS WASTE MANAGEMENT FACILITIES--Table of Contents
 
  Subpart H--Hazardous Waste Burned in Boilers and Industrial Furnaces
 
Sec. 266.100  Applicability.

    Source: 56 FR 7208, Feb. 21, 1991, unless otherwise noted.


    (a) The regulations of this subpart apply to hazardous waste burned 
or processed in a boiler or industrial furnace (as defined in 
Sec. 260.10 of this chapter) irrespective of the purpose of burning or 
processing, except as provided by paragraphs (b), (c), (d), (g), and (h) 
of this section. In this subpart, the term ``burn'' means burning for 
energy recovery or destruction, or processing for materials recovery or 
as an ingredient. The emissions standards of Secs. 266.104, 266.105, 
266.106, and 266.107 apply to facilities operating under interim status 
or under a RCRA permit as specified in Secs. 266.102 and 266.103.
    (b) Integration of the MACT standards. (1) Except as provided by 
paragraph (b)(2) of this section, the standards of this part no longer 
apply when an affected source demonstrates compliance with the maximum 
achievable control technology (MACT) requirements of part 63, subpart 
EEE, of this chapter by conducting a comprehensive performance test and 
submitting to the Administrator a Notification of Compliance under 
Secs. 63.1207(j) and 63.1210(b) of this chapter documenting compliance 
with the requirements of part 63, subpart EEE, of this chapter. 
Nevertheless, even after this demonstration of compliance with the MACT 
standards, RCRA permit conditions that were based on the standards of 
this part will continue to be in effect until they are removed from the 
permit or the permit is terminated or revoked, unless the permit 
expressly provides otherwise.
    (2) The following standards continue to apply:
    (i) If you elect to comply with Sec. 270.235(a)(1)(i) of this 
chapter to minimize emissions of toxic compounds from startup, shutdown, 
and malfunction events, Sec. 266.102(e)(1) requiring operations in 
accordance with the operating requirements specified in the permit at 
all times that hazardous waste

[[Page 10]]

is in the unit, and Sec. 266.102(e)(2)(iii) 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;
    (ii) The closure requirements of Secs. 266.102(e)(11) and 
266.103(l);
    (iii) The standards for direct transfer of Sec. 266.111;
    (iv) The standards for regulation of residues of Sec. 266.212; and
    (v) The applicable requirements of subparts A through H, BB and CC 
of parts 264 and 265 of this chapter.
    (c) The following hazardous wastes and facilities are not subject to 
regulation under this subpart:
    (1) Used oil burned for energy recovery that is also a hazardous 
waste solely because it exhibits a characteristic of hazardous waste 
identified in subpart C of part 261 of this chapter. Such used oil is 
subject to regulation under part 279 of this chapter;
    (2) Gas recovered from hazardous or solid waste landfills when such 
gas is burned for energy recovery;
    (3) Hazardous wastes that are exempt from regulation under 
Secs. 261.4 and 261.6(a)(3) (iii) and (iv) of this chapter, and 
hazardous wastes that are subject to the special requirements for 
conditionally exempt small quantity generators under Sec. 261.5 of this 
chapter; and
    (4) Coke ovens, if the only hazardous waste burned is EPA Hazardous 
Waste No. K087, decanter tank tar sludge from coking operations.
    (d) Owners and operators of smelting, melting, and refining furnaces 
(including pyrometallurgical devices such as cupolas, sintering 
machines, roasters, and foundry furnaces, but not including cement 
kilns, aggregate kilns, or halogen acid furnaces burning hazardous 
waste) that process hazardous waste solely for metal recovery are 
conditionally exempt from regulation under this subpart, except for 
Secs. 266.101 and 266.112.
    (1) To be exempt from Secs. 266.102 through 266.111, an owner or 
operator of a metal recovery furnace or mercury recovery furnace must 
comply with the following requirements, except that an owner or operator 
of a lead or a nickel-chromium recovery furnace, or a metal recovery 
furnace that burns baghouse bags used to capture metallic dusts emitted 
by steel manufacturing, must comply with the requirements of paragraph 
(d)(3) of this section, and owners or operators of lead recovery 
furnaces that are subject to regulation under the Secondary Lead 
Smelting NESHAP must comply with the requirements of paragraph (h) of 
this section.
    (i) Provide a one-time written notice to the Director indicating the 
following:
    (A) The owner or operator claims exemption under this paragraph;
    (B) The hazardous waste is burned solely for metal recovery 
consistent with the provisions of paragraph (d)(2) of this section;
    (C) The hazardous waste contains recoverable levels of metals; and
    (D) The owner or operator will comply with the sampling and analysis 
and recordkeeping requirements of this paragraph;
    (ii) Sample and analyze the hazardous waste and other feedstocks as 
necessary to comply with the requirements of this paragraph under 
procedures specified by Test Methods for Evaluating Solid Waste, 
Physical/Chemical Methods, SW-846, incorporated by reference in 
Sec. 260.11 of this chapter or alternative methods that meet or exceed 
the SW-846 method performance capabilities. If SW-846 does not prescribe 
a method for a particular determination, the owner or operator shall use 
the best available method; and
    (iii) Maintain at the facility for at least three years records to 
document compliance with the provisions of this paragraph 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.
    (2) A hazardous waste meeting either of the following criteria is 
not processed solely for metal recovery:
    (i) The hazardous waste has a total concentration of organic 
compounds listed in part 261, appendix VIII, of this chapter exceeding 
500 ppm by weight, as-fired, and so is considered to be

[[Page 11]]

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 must be retained in the 
records required by paragraph (d)(1)(iii) of this section; or
    (ii) 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 must be retained in the records required by paragraph 
(d)(1)(iii) of this section.
    (3) To be exempt from Secs. 266.102 through 266.111, an owner or 
operator of a lead or nickel-chromium or mercury recovery furnace 
(except for owners or operators of lead recovery furnaces subject to 
regulation under the Secondary Lead Smelting NESHAP) or a metal recovery 
furnace that burns baghouse bags used to capture metallic dusts emitted 
by steel manufacturing, must provide a one-time written notice to the 
Director identifying each hazardous waste burned and specifying whether 
the owner or operator claims an exemption for each waste under this 
paragraph or paragraph (d)(1) of this section. The owners or operator 
must comply with the requirements of paragraph (d)(1) of this section 
for those wastes claimed to be exempt under that paragraph and must 
comply with the requirements below for those wastes claimed to be exempt 
under this paragraph (d)(3).
    (i) The hazardous wastes listed in appendices XI, XII, and XIII, 
part 266, and baghouse bags used to capture metallic dusts emitted by 
steel manufacturing are exempt from the requirements of paragraph (d)(1) 
of this section, provided that:
    (A) A waste listed in appendix IX of this part must contain 
recoverable levels of lead, a waste listed in appendix XII of this part 
must contain recoverable levels of nickel or chromium, a waste listed in 
appendix XIII of this part must contain recoverable levels of mercury 
and contain less than 500 ppm of 40 CFR part 261, appendix VIII organic 
constituents, and baghouse bags used to capture metallic dusts emitted 
by steel manufacturing must contain recoverable levels of metal; and
    (B) The waste does not exhibit the Toxicity Characteristic of 
Sec. 261.24 of this chapter for an organic constituent; and
    (C) The waste is not a hazardous waste listed in subpart D of part 
261 of this chapter because it is listed for an organic constituent as 
identified in appendix VII of part 261 of this chapter; and
    (D) The owner or operator certifies in the one-time notice that 
hazardous waste is burned under the provisions of paragraph (d)(3) of 
this section and that sampling and analysis will be conducted or other 
information will be obtained as necessary to ensure continued compliance 
with these requirements. Sampling and analysis shall be conducted 
according to paragraph (d)(1)(ii) of this section and records to 
document compliance with paragraph (d)(3) of this section shall be kept 
for at least three years.
    (ii) The Director may decide on a case-by-case basis that the toxic 
organic constituents in a material listed in appendix XI, XII, or XIII 
of this part that contains a total concentration of more than 500 ppm 
toxic organic compounds listed in appendix VIII, part 261 of this 
chapter, may pose a hazard to human health and the environment when 
burned in a metal recovery furnace exempt from the requirements of this 
subpart. In that situation, after adequate notice and opportunity for 
comment, the metal recovery furnace will become subject to the 
requirements of this subpart when burning that material. In making the 
hazard determination, the Director will consider the following factors:
    (A) The concentration and toxicity of organic constituents in the 
material; and
    (B) The level of destruction of toxic organic constituents provided 
by the furnace; and

[[Page 12]]

    (C) Whether the acceptable ambient levels established in appendices 
IV or V of this part may be exceeded for any toxic organic compound that 
may be emitted based on dispersion modeling to predict the maximum 
annual average off-site ground level concentration.
    (e) The standards for direct transfer operations under Sec. 266.111 
apply only to facilities subject to the permit standards of Sec. 266.102 
or the interim status standards of Sec. 266.103.
    (f) The management standards for residues under Sec. 266.112 apply 
to any boiler or industrial furnace burning hazardous waste.
    (g) Owners and operators of smelting, melting, and refining furnaces 
(including pyrometallurgical devices such as cupolas, sintering 
machines, roasters, and foundry furnaces) that process hazardous waste 
for recovery of economically significant amounts of the precious metals 
gold, silver, platinum, paladium, irridium, osmium, rhodium, or 
ruthenium, or any combination of these are conditionally exempt from 
regulation under this subpart, except for Sec. 266.112. To be exempt 
from Secs. 266.101 through 266.111, an owner or operator must:
    (1) Provide a one-time written notice to the Director indicating the 
following:
    (i) The owner or operator claims exemption under this paragraph;
    (ii) The hazardous waste is burned for legitimate recovery of 
precious metal; and
    (iii) The owner or operator will comply with the sampling and 
analysis and recordkeeping requirements of this paragraph; and
    (2) Sample and analyze the hazardous waste as necessary to document 
that the waste is burned for recovery of economically significant 
amounts of precious metal using procedures specified by Test Methods for 
Evaluating Solid Waste, Physical/Chemical Methods, SW-846, incorporated 
by reference in Sec. 260.11 of this chapter or alternative methods that 
meet or exceed the SW-846 method performance capabilities. If SW-846 
does not prescribe a method for a particular determination, the owner or 
operator shall use the best available method; and
    (3) Maintain at the facility for at least three years records to 
document that all hazardous wastes burned are burned for recovery of 
economically significant amounts of precious metal.
    (h) Starting June 23, 1997, owners or operators of lead recovery 
furnaces that process hazardous waste for recovery of lead and that are 
subject to regulation under the Secondary Lead Smelting NESHAP, are 
conditionally exempt from regulation under this subpart, except for 
Sec. 266.101. To be exempt, an owner or operator must provide a one-time 
notice to the Director identifying each hazardous waste burned and 
specifying that the owner or operator claims an exemption under this 
paragraph. The notice also must state that the waste burned has a total 
concentration of non-metal compounds listed in part 261, appendix VIII, 
of this chapter of less than 500 ppm by weight, as fired and as provided 
in paragraph (d)(2)(i) of this section, or is listed in appendix XI to 
this part 266.
