What regulations govern which units may be used for burning off-specification used oil?

Used oil burners are subject to the regulations in Part 279 Subpart G, Standards for Used Oil Burners Who Burn Off-Specification Used Oil for Energy Recovery.

Off-specification used oil fuel may be burned for energy recovery in only the following devices:

- Industrial furnaces identified in §260.10
- Boilers, as defined in §260.10, that are identified as follows:
- Industrial boilers located on the site of a facility engaged in a manufacturing process where substances are transformed into new products, including the component parts of products, by mechanical or chemical processes
- Utility boilers used to produce electric power, steam, heated or cooled air, or other gases or fluids for sale
- Used oil-fired space heaters provided that the burner meets the provisions of §279.23
- Hazardous waste incinerators subject to regulation under Subpart O of Parts 264 or 265 (§279.61).

The used oil regulations include an exemption from the off-specification used oil burner requirements for used oil-fired space heaters provided the heater burns only used oil that the owner or operator generates or used oil received from household do-it-yourself (DIY) used oil generators (Memo, Bussard to Bosco; August 20, 1998 (RCRA Online #14280)).  To qualify, the space heaters must have a maximum capacity of 0.5 million Btu per hour and the combustion gases must be vented into the ambient air (§279.23).
