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.
