40 CFR § 279.70 - Applicability.

(1) Directs a shipment of off-specification used oil from their facility to a used oil burner; or
(2) First claims that used oil that is to be burned for energy recovery meets the used oil fuel specifications set forth in § 279.11.
(b) The following persons are not marketers subject to this subpart:
(1) Used oil generators, and transporters who transport used oil received only from generators, unless the generator or transporter directs a shipment of off-specification used oil from their facility to a used oil burner.

(2) Persons who direct shipments of on-specification used oil and who are not the first person to claim the oil meets the used oil fuel specifications of § 279.11.
(c) Any person subject to the requirements of this Subpart must also comply with one of the following:
(1) Subpart C of this part—Standards for Used Oil Generators;
(2) Subpart E of this part—Standards for Used Oil Transporters and Transfer Facilities;
(3) Subpart F of this part—Standards for Used Oil Processors and Re-refiners; or
