PART 279--STANDARDS FOR THE MANAGEMENT OF USED OIL--Table of Contents
 
              Subpart C--Standards for Used Oil Generators
 
Sec. 279.21  Hazardous waste mixing.

    (a) Mixtures of used oil and hazardous waste must be managed in 
accordance with Sec. 279.10(b).
    (b) The rebuttable presumption for used oil of Sec. 279.10(b)(1)(ii) 
applies to used oil managed by generators. Under the rebuttable 
presumption for used oil of Sec. 279.10(b)(1)(ii), used oil containing 
greater than 1,000 ppm total halogens is presumed to be a hazardous 
waste and thus must be managed as hazardous waste and not as used oil 
unless the presumption is rebutted. However, the rebuttable presumption 
does not apply to certain metalworking oils/fluids and certain used oils 
removed from refrigeration units.
