25 Pa. Code § 298.63
(b) The waste oil burner shall determine if the waste oil contains above or below 1,000 parts per million total halogens by one of the following:
(c) Waste oil containing more than 1,000 parts per million total halogens, is presumed to be a hazardous waste because it has been mixed with halogenated hazardous waste listed under 40 CFR Part 261, Subpart D (relating to lists of hazardous waste), incorporated by reference in § 261a.1 (relating to incorporation by reference, purpose and scope). A person may rebut this presumption by demonstrating that the waste oil does not contain hazardous waste. For example, by using an analytical method from the current edition of SW-846 to show that the waste oil does not contain significant concentrations of halogenated hazardous constituents identified in 40 CFR Part 261, Appendix VIII (relating to hazardous constituents), incorporated by reference in § 261a.1. EPA publication SW-846, current edition, is available from the Government Printing Office, Superintendent of Documents, Post Office Box 371954, Pittsburgh, Pennsylvania 15250-7954, (202) 512-1800 (Document number 955-001-00000-1). Another way of rebutting this presumption is to demonstrate that the halogenated constituents are from wastes generated by households and, therefore, under 40 CFR 261.4(b)(1) (relating to exclusions), incorporated by reference in § 261a.1 are excluded from regulation as hazardous waste.
