260 through 266, 268, 270, and 124 of this chapter.
    (a) Used oil. EPA presumes that used oil is to be recycled unless a 
used oil handler disposes of used oil, or sends used oil for disposal. 
Except as provided in Sec. 279.11, the regulations of this part apply 
to used oil, and to materials identified in this section as being 
subject to regulation as used oil, whether or not the used oil or 
material exhibits any characteristics of hazardous waste identified in 
subpart C of part 261 of this chapter.
    (b) Mixtures of used oil and hazardous waste--(1) Listed hazardous 
waste. (i) Mixtures of used oil and hazardous waste that is listed in 
subpart D of part 261 of this chapter are subject to regulation as 
hazardous waste under parts 260 through 266, 268, 270, and 124 of this 
chapter, rather than as used oil under this part.
    (ii) Rebuttable presumption for used oil. Used oil containing more 
than 1,000 ppm total halogens is presumed to be a hazardous waste 
because it has been mixed with halogenated hazardous waste listed in 
subpart D of part 261 of this chapter. Persons may rebut this 
presumption by demonstrating that the used oil does not contain 
hazardous waste (for example, by showing that the used oil does not 
contain significant concentrations of halogenated hazardous constituents 
listed in appendix VIII of part 261 of this chapter).
    (A) The rebuttable presumption does not apply to metalworking oils/
fluids containing chlorinated paraffins, if they are processed, through 
a tolling arrangement as described in Sec. 279.24(c), to reclaim 
metalworking oils/fluids. The presumption does apply to metalworking 
oils/fluids if such oils/fluids are recycled in any other manner, or 
disposed.
    (B) The rebuttable presumption does not apply to used oils 
contaminated with chlorofluorocarbons (CFCs) removed from refrigeration 
units where the CFCs are destined for reclamation. The rebuttable 
presumption does apply to used oils contaminated with CFCs that have 
been mixed with used oil from sources other than refrigeration units.
    (2) Characteristic hazardous waste. Mixtures of used oil and 
hazardous waste that solely exhibit one or more of the hazardous waste 
characteristics identified in subpart C of part 261 of this chapter and 
mixtures of used oil and hazardous waste that is listed in subpart D 
solely because it exhibits one or more of the characteristics of 
hazardous waste identified in subpart C are subject to:
    (i) Except as provided in paragraph (b)(2)(iii) of this section, 
regulation as hazardous waste under parts 260 through 266, 268, 270, and 
124 of this chapter rather than as used oil under this part, if the 
resultant mixture exhibits any characteristics of hazardous waste 
identified in subpart C of part 261 of this chapter; or
    (ii) Except as specified in Sec. 279.10(b)(2)(iii) regulation as 
used oil under this part, if the resultant mixture does not exhibit any 
characteristics of hazardous waste identified under subpart C of part 
261 of this chapter.
    (iii) Regulation as used oil under this part, if the mixture is of 
used oil and a waste which is hazardous solely because it exhibits the 
characteristic of ignitability (e.g., ignitable-only mineral spirits), 
provided that the resultant mixture does not exhibit the characteristic 
of ignitability under Sec. 261.21 of this chapter.
    (3) Conditionally exempt small quantity generator hazardous waste. 
Mixtures of used oil and conditionally exempt small quantity generator 
hazardous waste regulated under Sec. 261.5 of this chapter are subject 
to regulation as used oil under this part.
    (c) Materials containing or otherwise contaminated with used oil. 
(1) Except as provided in paragraph (c)(2) of this section, materials 
containing or otherwise contaminated with used oil from which the used 
oil has been properly drained or removed to the extent possible such 
that no visible signs of free-flowing oil remain in or on the material:
    (i) Are not used oil and thus not subject to this part, and
    (ii) If applicable are subject to the hazardous waste regulations of 
parts 124, 260 through 266, 268, and 270 of this chapter.
    (2) Materials containing or otherwise contaminated with used oil 
that are burned for energy recovery are subject

[[Page 477]]

to regulation as used oil under this part.
    (3) Used oil drained or removed from materials containing or 
otherwise contaminated with used oil is subject to regulation as used 
oil under this part.
    (d) Mixtures of used oil with products. (1) Except as provided in 
paragraph (d)(2) of this section, mixtures of used oil and fuels or 
other fuel products are subject to regulation as used oil under this 
part.
    (2) Mixtures of used oil and diesel fuel mixed on-site by the 
generator of the used oil for use in the generator's own vehicles are 
not subject to this part once the used oil and diesel fuel have been 
mixed. Prior to mixing, the used oil is subject to the requirements of 
subpart C of this part.
    (e) Materials derived from used oil. (1) Materials that are 
reclaimed from used oil that are used beneficially and are not burned 
for energy recovery or used in a manner constituting disposal (e.g., re-
refined lubricants) are:
    (i) Not used oil and thus are not subject to this part, and
    (ii) Not solid wastes and are thus not subject to the hazardous 
waste regulations of parts 260 through 266, 268, 270, and 124 of this 
chapter as provided in Sec. 261.3(c)(2)(i) of this chapter.
    (2) Materials produced from used oil that are burned for energy 
recovery (e.g., used oil fuels) are subject to regulation as used oil 
under this part.
    (3) Except as provided in paragraph (e)(4) of this section, 
materials derived from used oil that are disposed of or used in a manner 
constituting disposal are:
    (i) Not used oil and thus are not subject to this Part, and
    (ii) Are solid wastes and thus are subject to the hazardous waste 
regulations of parts 260 through 266, 268, 270, and 124 of this chapter 
if the materials are listed or identified as hazardous wastes.
    (4) Used oil re-refining distillation bottoms that are used as 
feedstock to manufacture asphalt products are not subject to this part.
    (f) Wastewater. Wastewater, the discharge of which is subject to 
regulation under either section 402 or section 307(b) of the Clean Water 
Act (including wastewaters at facilities which have eliminated the 
discharge of wastewater), contaminated with de minimis quantities of 
used oil are not subject to the requirements of this part. For purposes 
of this paragraph, ``de minimis'' quantities of used oils are defined as 
small spills, leaks, or drippings from pumps, machinery, pipes, and 
other similar equipment during normal operations or small amounts of oil 
lost to the wastewater treatment system during washing or draining 
operations. This exception will not apply if the used oil is discarded 
as a result of abnormal manufacturing operations resulting in 
substantial leaks, spills, or other releases, or to used oil recovered 
from wastewaters.
    (g) Used oil introduced into crude oil pipelines or a petroleum 
refining facility. (1) Used oil mixed with crude oil or natural gas 
liquids (e.g., in a production separator or crude oil stock tank) for 
insertion into a crude oil pipeline is exempt from the requirements of 
this part. The used oil is subject to the requirements of this part 
prior to the mixing of used oil with crude oil or natural gas liquids.
    (2) Mixtures of used oil and crude oil or natural gas liquids 
containing less than 1% used oil that are being stored or transported to 
a crude oil pipeline or petroleum refining facility for insertion into 
the refining process at a point prior to crude distillation or catalytic 
cracking are exempt from the requirements of this part.
    (3) Used oil that is inserted into the petroleum refining facility 
process before crude distillation or catalytic cracking without prior 
mixing with crude oil is exempt from the requirements of this part 
provided that the used oil constitutes less than 1% of the crude oil 
feed to any petroleum refining facility process unit at any given time. 
Prior to insertion into the petroleum refining facility process, the 
used oil is subject to the requirements of this part.
    (4) Except as provided in paragraph (g)(5) of this section, used oil 
that is introduced into a petroleum refining facility process after 
crude distillation or catalytic cracking is exempt from the requirements 
of this part only if the used oil meets the specification of Sec. 
279.11. Prior to insertion into the petroleum refining facility process, 
the

[[Page 478]]

used oil is subject to the requirements of this part.
    (5) Used oil that is incidentally captured by a hydrocarbon recovery 
system or wastewater treatment system as part of routine process 
operations at a petroleum refining facility and inserted into the 
petroleum refining facility process is exempt from the requirements of 
this part. This exemption does not extend to used oil which is 
intentionally introduced into a hydrocarbon recovery system (e.g., by 
pouring collected used oil into the waste water treatment system).
    (6) Tank bottoms from stock tanks containing exempt mixtures of used 
oil and crude oil or natural gas liquids are exempt from the 
requirements of this part.
    (h) Used oil on vessels. Used oil produced on vessels from normal 
shipboard operations is not subject to this part until it is transported 
ashore.
    (i) Used oil containing PCBs. Used oil containing PCBs (as defined 
at 40 CFR 761.3) at any concentration less than 50 ppm is subject to the 
requirements of this Part unless, because of dilution, it is regulated 
under 40 CFR Part 761 as a used oil containing PCBs at 50 ppm or 
greater. PCB-containing used oil subject to the requirements of this 
Part may also be subject to the prohibitions and requirements found at 
40 CFR Part 761, including Sec. 761.20(d) and (e). Used oil containing 
PCBs at concentrations of 50 ppm or greater is not subject to the 
requirements of this Part, but is subject to regulation under 40 CFR 
Part 761. No person may avoid these provisions by diluting used oil 
containing PCBs, unless otherwise specifically provided for in this Part 
or Part 761 of this chapter.
