35 Ill. Adm. Code 720.121
Alternative Equivalent Testing Methods
Section 720
Section 720.121 Alternative
Equivalent Testing Methods
a) The Agency has no authority to alter the universe of regulated
wastes. Modification of testing methods that are stated in 35 Ill. Adm. Code
721 requires rulemaking under Section 720.120. However, deviation from these
methods is allowed under 35 Ill. Adm. Code 721, as observed, for example, in
the Board Note appended to 35 Ill. Adm. Code 721.120(c).
b) The Agency may approve alternative equivalent testing methods
for a particular person's use to determine whether specified waste streams are
subject to these regulations. This must be done by permit condition or letter.
Any petition to the Board or request to the Agency concerning alternative
equivalent testing methods must include the information required by 40 CFR
260.21(b), incorporated by reference in 35 Ill. Adm. Code 720.111(b).
c) The testing methods specified in 35 Ill. Adm. Code 721 or
alternative equivalent testing methods approved by the Agency need not be
applied to identify or distinguish waste streams that are known, admitted, or
assumed to be subject to these regulations. In this case, any method may be
used, subject to the Agency's authority to approve the testing procedures used.
d) If USEPA amends the federal regulations to allow the use of a
new testing method, USEPA has stated that it will incorporate the new method by
reference in 40 CFR 260.11 and add it to "Test Methods for Evaluating
Solid Waste, Physical/Chemical Methods", USEPA publication number EPA-530/SW-846,
incorporated by reference in Section 720.111(b).
e) Alternative equivalent testing methods will not be approved if
the result of the approval would make the Illinois RCRA Subtitle C program less
than substantially equivalent to the federal.
