6 Colo. Code Regs. § 1007-3-279.10

Current through Register Vol. 47, No. 20, October 25, 2024

Section 6 CCR 1007-3-279.10 - Applicability

This section identifies those materials which are subject to regulation as used oil under this part. This section also identifies some materials that are not subject to regulation as used oil under this part, and indicates whether these materials may be subject to regulation as hazardous waste under Parts 260 through 268, and Part 100 of these regulations.

(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 § 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 these regulations.

(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 these regulations are subject to regulation as hazardous waste under Parts 260 through 268, and Part 100 of these regulations, 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 these regulations. 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 these regulations).

(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 § 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.

(i) 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 these regulations 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:

(A) Except as provided in paragraph (b)(2)(i)(C) of this section, regulation as hazardous waste under Parts 260 through 268, and Part 100 of these regulations 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 these regulations; or

(B) 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 these regulations.

(C) 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 § 261.21 of these regulations.

(ii) The mixing of used oil and a hazardous waste that solely exhibits one or more of the hazardous waste characteristics identified in Subpart C of Part 261 of these regulations or the mixing of used oil and a hazardous waste that is listed in Subpart D of Part 261 of these regulations solely because it exhibits one or more of the characteristics of hazardous waste identified in Subpart C for the purpose of managing the resultant mixture as a used oil constitutes treatment of a hazardous waste and is subject to Part 100 of these regulations.

(3)Reserved.

(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 260 through 268, and Part 100 of these regulations.

(2) Materials containing or otherwise contaminated with used oil that are burned for energy recovery are subject 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 268, and Part 100 of these regulations as provided in § 261.3(c)(2)(i) of these regulations.

(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 268, and Part 100 of these regulations 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 § 279.11. Prior to insertion into the petroleum refining facility process, the 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 wastewater 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 Part 279 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 Part 279 may also be subject to the prohibitions and requirements found at 40 CFR Part 761, including § 761.20(d) and (e). Used oil containing PCBs at concentrations of 50 ppm or greater is not subject to the requirements of Part 279, 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 279 or 40 CFR Part 761. 40 CFR part 761 is incorporated by reference to include those versions in effect as of the date this regulation was adopted, and does not include later amendments to the incorporated material. Materials incorporated by reference are available for public inspection during normal business hours from the Hazardous Materials and Waste Management Division, 4300 Cherry Creek Drive South, Denver, CO 80246.
