Current through Register Vol. 48, No. 38, September 20, 2024
a)
Wastes from wood preserving processes at plants that do not resume or initiate
use of chlorophenolic preservatives will not meet the listing definition of
F032 once the generator has met all of the requirements of subsections (b) and
(c). These wastes may, however, continue to meet another hazardous waste
listing description or may exhibit one or more of the hazardous waste
characteristics.
b) Generators must
either clean or replace all process equipment that may have come into contact
with chlorophenolic formulations or constituents thereof, including, but not
limited to, treatment cylinders, sumps, tanks, piping systems, drip pads, fork
lifts and trams, in a manner that minimizes or eliminates the escape of
hazardous waste or constituents, leachate, contaminated drippage or hazardous
waste decomposition products to the groundwater, surface water, or atmosphere.
1) Generators must do one of the following:
A) Prepare and follow an equipment cleaning
plan and clean equipment in accordance with subsection (b)(2); or
B) Prepare and follow an equipment
replacement plan and replace equipment in accordance with subsection (b)(3);
or
C) Document cleaning and
replacement in accordance with subsections (b)(2) and (b)(3), carried out after
termination of use of chlorophenolic preservatives.
2) Cleaning requirements.
A) The generator must prepare and sign a
written equipment cleaning plan that describes the following:
i) The equipment to be cleaned;
ii) How the equipment will be
cleaned;
iii) The solvent to be
used in cleaning;
iv) How solvent
rinses will be tested; and
v) How
cleaning residues will be disposed of.
B) Equipment must be cleaned as follows:
i) Remove all visible residues from process
equipment; and
ii) Rinse process
equipment with an appropriate solvent until dioxins and dibenzofurans are not
detected in the final solvent rinse.
C) Analytical requirements.
i) Rinses must be tested by using an
appropriate method.
ii) "Not
detected" means at or below the following lower method calibration limit (MCL):
the 2,3,7,8-TCDD-based MCL is 0.01 parts per trillion (ppt), using a sample
weight of 1000 g, an IS spiking level of 1 ppt, and a final extraction volume
of 10 to 50 µl. For other congeners, multiply the values by 1 for TCDF,
PeCDD, or PeCDF; by 2.5 for HxCDD, HxCDF, HpCDD, or HpCDF; or by 5 for OCDD or
OCDF.
D) The generator
must manage all residues from the cleaning process as F032 waste.
3) Replacement requirements.
A) The generator must prepare and sign a
written equipment replacement plan that describes the following:
i) The equipment to be replaced;
ii) How the equipment will be replaced;
and
iii) How the equipment will be
disposed of.
B) The
generator must manage the discarded equipment as F032 waste.
4) Documentation requirements. The
generator must document that previous equipment cleaning and replacement was
performed in accordance with subsections (b)(2) and (b)(3) and that the
equipment cleaning and replacement occurred after cessation of use of
chlorophenolic preservatives.
c) The generator must maintain the following
records documenting the cleaning and replacement as part of the facility's
operating record:
1) The name and address of
the facility;
2) Formulations
previously used and the date on which their use ceased in each process at the
plant;
3) Formulations currently
used in each process at the plant;
4) The equipment cleaning or replacement
plan;
5) The name and address of
any persons who conducted the cleaning and replacement;
6) The dates on which cleaning and
replacement were accomplished;
7)
The dates of sampling and testing;
8) A description of the sample handling and
preparation techniques used for extraction, containerization, preservation and
chain-of-custody of the samples;
9)
A description of the tests performed, the date the tests were performed and the
results of the tests;
10) The name
and model numbers of the instruments used in performing the tests;
11) QA/QC documentation; and
12) The following statement signed by the
generator or the generator's authorized representative:
I certify under penalty of law that all process equipment
required to be cleaned or replaced under 35 Ill. Adm. Code
721.135
was cleaned or replaced as represented in the equipment cleaning and
replacement plan and accompanying documentation. I am aware that there are
significant penalties for providing false information, including the
possibility of fine or imprisonment.
