An industrial solid waste is a Class 3 waste if it is inert and essentially
insoluble, and poses no threat to human health and/or the environment. Class
3 wastes include, but are not limited to, materials such as rock, brick, glass,
dirt, and certain plastics and rubber, which are not readily decomposable.
An industrial solid waste is a Class 3 waste if it:
(1) is not a hazardous waste pursuant to §335.504 of this
title (relating to Hazardous Waste Determination);
(2) does not meet any of the Class 1 waste criteria set forth
in §335.505 of this title (relating to Class 1 Waste Determination);
and
(3) is inert. Inertness refers to chemical inactivity of an
element, compound, or a waste. Ingredients added to mixtures chiefly for bulk
and/or weight purposes are normally considered inert; and
(4) is essentially insoluble.
(A) Essential insolubility is established:
(i) when, using the test methods specified in §335.521(d)
of this title (relating to Appendix 4 (Seven-Day Distilled Water Leachate
Test)), the extract(s) from the representative sampling of the waste does
not leach greater than the Maximum Contaminant Levels listed in §335.521(a)(3)
of this title (relating to Appendix 1, Table 3); and
(ii) using the test methods described in 40 Code of Federal
Regulations Part 261, Appendix II, or equivalent methods approved by the executive
director under the procedures set forth in §335.509 of this title (relating
to Waste Analysis), the extract(s) from the representative sampling of the
waste does not exhibit detectable levels of constituents found in §335.521(a)(1)
of this title (relating to Appendix 1, Table 1) including constituents in §335.521(a)(3)
of this title which are marked with an asterisk. This excludes the constituents
listed in §335.521(a)(3) of this title which were addressed in clause
(i) of this subparagraph; and
(iii) when using an appropriate test method, representative
sampling of the waste does not exhibit detectable levels of total petroleum
hydrocarbon (TPH). "Petroleum substance wastes" as defined in §334.481
of this title (relating to Definitions) are not subject to this subsection;
and
(iv) when, using an appropriate test method, representative
sampling of the waste does not exhibit detectable levels of polychlorinated
biphenyls (PCBs).
(B) Subparagraph (A) of this paragraph does not apply to naturally
occurring material, i.e., soil, rock, etc., if the generator can demonstrate
that the levels present in the waste are naturally occurring in the background
of that particular material.
(C) If the detection level submitted by the generator is challenged
by the executive director or the commission, and for other enforcement purposes,
the burden is on the generator to demonstrate that the detection level was
reasonable for the material in question and for the technology in use at the
time the waste was classified.
