Current through Register Vol. 48, No. 38, September 20, 2024
a)
Each owner or operator subject to the provisions of this Subpart BB must comply
with the test methods and procedures requirements provided in this
Section.
b) Leak detection
monitoring, as required in Sections
724.952
through
724.962,
must comply with the following requirements:
1) Monitoring must comply with Reference
Method 21 (Determination of Volatile Organic Compound Leaks) in appendix A to
40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code
720.111(b).
2) The detection instrument must meet the
performance criteria of Reference Method 21.
3) The instrument must be calibrated before
use on each day of its use by the procedures specified in Reference Method
21.
4) Calibration gases must be as
follows:
A) Zero air (less than 10 ppm of
hydrocarbon in air); and
B) A
mixture of methane or n-hexane and air at a concentration of approximately, but
less than 10,000 ppm methane or n-hexane.
5) The instrument probe must be traversed
around all potential leak interfaces as close to the interface as possible as
described in Reference Method 21.
c) When equipment is tested for compliance
with no detectable emissions, as required in Sections
724.952(e),
724.953(i),
724.954,
and
724.957(f),
the test must comply with the following requirements:
1) The requirements of subsections (b)(1)
through (b)(4) apply.
2) The
background level must be determined as set forth in Reference Method
21.
3) The instrument probe must be
traversed around all potential leak interfaces as close to the interface as
possible as described in Reference Method 21.
4) This arithmetic difference between the
maximum concentration indicated by the instrument and the background level is
compared with 500 ppm for determining compliance.
d) In accordance with the waste analysis plan
required by Section
724.113(b),
an owner or operator of a facility must determine, for each piece of equipment,
whether the equipment contains or contacts a hazardous waste with organic
concentration that equals or exceeds 10 percent by weight using the following:
1) Methods described in ASTM Methods D
2267-88 (Standard Test Method for Aromatics in Light Naphthas and Aviation
Gasolines by Gas Chromatography), E 168-88 (Standard Practices for General
Techniques of Infrared Quantitative Analysis), E 169-87 (Standard Practices for
General Techniques of Ultraviolet-Visible Quantitative Analysis), or E 260-85
(Standard Practice for Packed Column Gas Chromatography), each incorporated by
reference in 35 Ill. Adm. Code
720.111(a);
2) Method 9060A (Total Organic Carbon) of
"Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", USEPA
publication number EPA-530/SW-846, incorporated by reference in 35 Ill. Adm.
Code
720.111(a),
for computing total organic concentration of the sample, or analyzed for its
individual constituents; or
3)
Application of the knowledge of the nature of the hazardous wastestream or the
process by which it was produced. Documentation of a waste determination by
knowledge is required. Examples of documentation that must be used to support a
determination under this provision include production process information
documenting that no organic compounds are used, information that the waste is
generated by a process that is identical to a process at the same or another
facility that has previously been demonstrated by direct measurement to have a
total organic content less than 10 percent, or prior speciation analysis
results on the same wastestream where it is also documented that no process
changes have occurred since that analysis that could affect the waste total
organic concentration.
e)
If an owner or operator determines that a piece of equipment contains or
contacts a hazardous waste with organic concentrations at least 10 percent by
weight, the determination can be revised only after following the procedures in
subsection (d)(1) or (d)(2).
f)
When an owner or operator and the Agency do not agree on whether a piece of
equipment contains or contacts a hazardous waste with organic concentrations at
least 10 percent by weight, the procedures in subsection (d)(1) or (d)(2) must
be used to resolve the dispute.
g)
Samples used in determining the percent organic content must be representative
of the highest total organic content hazardous waste that is expected to be
contained in or contact the equipment.
h) To determine if pumps or valves are in
light liquid service, the vapor pressures of constituents must either be
obtained from standard reference texts or be determined by ASTM D 2879-92
(Standard Test Method for Vapor Pressure-Temperature Relationship and Initial
Decomposition Temperature of Liquids by Isoteniscope), incorporated by
reference in 35 Ill. Adm. Code
720.111(a).
i) Performance tests to determine if a
control device achieves 95 weight percent organic emission reduction must
comply with the procedures of Section
724.934(c)(1) through
(c)(4).
