(7) One kilogram of any combination of wastes identified in §C(1), (2), and (6) of this regulation.
D. In order for hazardous waste to be excluded from regulation under this chapter, the generator:
(1) Shall comply with COMAR 26.13.03.02—.02-2, which concern hazardous waste determination;
(2) Shall treat or dispose of the waste in an on-site facility, or ensure delivery to an off-site treatment, storage, or disposal facility, either of which, if located in the United States, is:
(a) Permitted by EPA under 40 CFR 270, or by a state with a hazardous waste management program authorized under 40 CFR 271;
(b) In interim status under:
(i) 40 CFR 270 and 265; or
(ii) COMAR 26.13.06 and 26.13.07;
(c) A facility that is:
(i) Permitted, licensed, or registered by a state to manage municipal solid waste or nonmunicipal, nonhazardous solid waste;
(ii) In compliance with the requirements of 40 CFR 258 or equivalent state regulations, if the waste is managed in a municipal solid waste landfill;

E. Mixed Hazardous Wastes.
(1) Except as provided in §E(2), hazardous waste subject to the reduced requirements of this chapter may be mixed with non-hazardous waste and remain subject to these reduced requirements even though the resultant mixture exceeds the quantity limitations identified in this chapter, unless the mixture meets any of the characteristics of hazardous waste identified in Regulations .10—.14 of this chapter.
(2) If a generator's hazardous waste is mixed with used oil, the mixture is subject to regulation under applicable provisions of COMAR 26.10.15, 26.11.09, 26.13.04.01D(4), and 26.13.10.05, if it is destined to be burned for energy recovery.
