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.

 Indicates the statutory source as defined by 1, 2, 3, and 4 below.
 No reporting of releases of this hazardous substance is required if the diameter of the pieces of the solid metal released is equal to
  or exceeds 100 micrometers (0.004 inches).
 The RQ for asbestos is limited to friable forms only.
1--indicates that the statutory source for designation of this hazardous substance under CERCLA is CWA Section 311(b)(4).
2--indicates that the statutory source for designation of this hazardous substance under CERCLA is CWA Section 307(a).
3--indicates that the statutory source for designation of this hazardous substance under CERCLA is CAA Section 112.
4--Indicates that the statutory source for designation of this hazardous substance under CERCLA is RCRA Section 3001.
1*--indicates that the 1-pound RQ is a CERCLA statutory RQ.
 Indicates that the RQ is subject to change when the assessment of potential carcinogenicity is completed.
 The Agency may adjust the statutory RQ for this hazardous substance in a future rulemaking; until then the statutory RQ applies.
Sec. --The adjusted RQs for radionuclides may be found in appendix B to this table.
**--indicates that no RQ is being assigned to the generic or broad class.
a Benzene was already a CERCLA hazardous substance prior to the CAA Amendments of 1990 and received an adjusted 10-pound RQ based on potential
  carcinogenicity in an August 14, 1989, final rule (54 FR 33418). The CAA Amendments specify that ``benzene (including benzene from gasoline)'' is a
  hazardous air pollutant and, thus, a CERCLA hazardous substance.
b The CAA Amendments of 1990 list DDE (3547-04-4) as a CAA hazardous air pollutant. The CAS number, 3547-04-4, is for the chemical, p,p'-
  dichlorodiphenylethane. DDE or p,p'-dichlorodiphenyldichloroethylene, CAS number 72-55-9, is already listed in table 302.4 with a final RQ of 1 pound.
  The substance identified by the CAS number 3547-04-4 has been evaluated and listed as DDE to be consistent with the CAA section 112 listing, as
  amended.
c Includes mineral fiber emissions from facilities manufacturing or processing glass, rock, or slag fibers (or other mineral derived fibers) of average
  diameter 1 micrometer or less.
d Includes mono- and di-ethers of ethylene glycol, diethylene glycol, and triethylene glycol R-(OCH2CH2)n-OR' where
    n=1, 2, or 3
    R=alkyl or aryl groups
    R'=R, H, or groups which, when removed, yield glycol ethers with the structure: R-(OCH2CH2)n--OH. Polymers are excluded from the glycol category.
e Includes organic compounds with more than one benzene ring, and which have a boiling point greater than or equal to 100  deg.C.
f See 40 CFR 302.6(b)(1) for application of the mixture rule to this hazardous waste.

Ci--Curie. The curie represents a rate of radioactive decay. One curie
  is the quantity of any radioactive nuclide which undergoes 3.7E 10
  disintegrations per second.
Bq--Becquerel. The becquerel represents a rate of radioactive decay. One
  becquerel is the quantity of any radioactive nuclide which undergoes
  one disintegration per second. One curie is equal to 3.7E 10
  becquerel.
@--Final RQs for all radionuclides apply to chemical compounds
  containing the radionuclides and elemental forms regardless of the
  diameter of pieces of solid material.
&--The adjusted RQ of one curie applies to all radionuclides not
  otherwise listed. Whenever the RQs in table 302.4 and this appendix to
  the table are in conflict, the lowest RQ shall apply. For example,
  uranyl acetate and uranyl nitrate have adjusted RQs shown in table
  302.4 of 100 pounds, equivalent to about one-tenth the RQ level for
  uranium-238 listed in this appendix.
E--Exponent to the base 10. For example, 1.3E 2 is equal to 130 while
  1.3E 3 is equal to 1300.
m--Signifies a nuclear isomer which is a radionuclide in a higher energy
  metastable state relative to the parent isotope.
--Notification requirements for releases of mixtures or
  solutions of radionuclides can be found in Sec.  302.6(b) of this
  rule. Final RQs for the following four common radionuclide mixtures
  are provided: radium-226 in secular equilibrium with its daughters
  (0.053 curie); natural uranium (0.1 curie); natural uranium in secular
  equilibrium with its daughters (0.052 curie); and natural thorium in
  secular equilibrium with its daughters (0.011 curie).
