Haw. Code R. § 11-279-11
Used oil burned for energy recovery, and any fuel produced from used oil by processing, blending, or other treatment, is subject to regulation under this chapter unless it is shown not to exceed any of the allowable levels of the constituents and properties in the specification shown in Table 1. Once used oil that is to be burned for energy recovery has been shown not to exceed any specification and the person making that showing complies with sections 11-279-72, 11-279-73, and 11-279-74(b), the used oil is no longer subject to this chapter.
Table 1-Used Oil Not exceeding Any Specification Level Is Not Subject to This Part When Burned for Energy
Recovery1
| Constituent/property | Allowable level |
| Arsenic | 5 ppm maximum |
| Cadmium | 2 ppm maximum. |
| Chromium | 10 ppm maximum. |
| Lead | 100 ppm maximum. |
| Flash point | 100 °F minimum. |
| Total halogens | 4,000 ppm maximum.2 |
| PCBs Note: Applicable standards for the burning of used oil containing PCBs are also imposed by 40 CFR 761.20(e). | 2 ppm maximum |
FOOTNOTE: 1The specification does not apply to mixtures of used oil and hazardous waste that continue to be regulated as hazardous waste (see section 11-279-10(b)) . FOOTNOTE: 2Used oil containing more than 1,000 ppm total halogens is presumed to be a hazardous waste under the rebuttable presumption provided under section 11-279-10(b)(1). Such used oil is subject to subchapter H of chapter 11-266 rather than this chapter when burned for energy recovery unless the presumption of mixing can be successfully rebutted.
