PART 302--DESIGNATION, REPORTABLE QUANTITIES, AND NOTIFICATION--Table of Contents
 
Sec. 302.4  Designation of hazardous substances.

    (a) Listed hazardous substances. The elements and compounds and 
hazardous wastes appearing in table 302.4 are designated as hazardous 
substances under section 102(a) of the Act.
    (b) Unlisted hazardous substances. A solid waste, as defined in 40 
CFR 261.2, which is not excluded from regulation as a hazardous waste 
under 40 CFR 261.4(b), is a hazardous substance under section 101(14) of 
the Act if it exhibits any of the characteristics identified in 40 CFR 
261.20 through 261.24.
    Note: The numbers under the column headed ``CASRN'' are the Chemical 
Abstracts Service Registry Numbers for each hazardous substance. Other 
names by which each hazardous substance is identified in other statutes 
and their implementing regulations are provided in the ``Regulatory 
Synonyms'' column. The ``Statutory RQ'' column lists the RQs for 
hazardous substances established by section 102 of CERCLA. The 
``Statutory Code'' column indicates the statutory source for designating 
each substance as a CERCLA hazardous substance: ``1'' indicates that the 
statutory source is section 311(b)(4) of the Clean Water Act, ``2'' 
indicates that the source is section 307(a) of the Clean Water Act, 
``3'' indicates that the source is section 112 of the Clean Air Act, and 
``4'' indicates that the source is RCRA section 3001. The ``RCRA Waste 
Number'' column provides the waste identification numbers assigned to 
various substances by RCRA regulations. The column headed ``Category'' 
lists the code letters ``X,'' ``A,'' ``B,'' ``C,'' and ``D,'' which are 
associated with reportable quantities of 1, 10, 100, 1000, and 5000 
pounds, respectively. The ``Pounds (kg)'' column provides the reportable 
quantity adjustment for each hazardous substance in pounds and 
kilograms.
