Current through Register Vol. 49, No. 13, September 23, 2024
Subpart
1.
Scope.
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 subparts
2 and
3. These wastes may, however,
continue to meet another hazardous waste listing description or may exhibit one
or more of the characteristics of hazardous waste.
Subp. 2.
Process equipment cleaning and
replacement.
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. Cleaning and
replacement of process equipment must be performed in a manner which minimizes
or eliminates the escape of hazardous waste or waste constituents, leachate,
contaminated drippage, or hazardous waste decomposition products to the
groundwater, surface water, or atmosphere. Generators must either:
A. prepare and follow an equipment cleaning
plan and clean equipment in accordance with this item by:
(1) preparing and following a written
equipment cleaning plan that describes the equipment to be cleaned, how the
equipment will be cleaned, the solvent chosen to be used in the cleaning, how
solvent rinses will be tested, and how cleaning residues will be
disposed;
(2) removing all visible
residues from process equipment and rinsing process equipment with an
appropriate solvent until dioxins and dibenzofurans in the final solvent rinse
are found to be at or below the lower method calibration limit (MCL) found in
SW-846, Method 8290, Table 1; and
(3) managing all residues from the cleaning
process as F032 waste;
B. prepare, sign, and follow a written
equipment replacement plan that describes the equipment to be replaced, how the
equipment will be replaced, and how the equipment will be disposed of as F032
waste; or
C. document that previous
equipment cleaning and/or replacement was performed in accordance with this
part and occurred after cessation of use of chlorophenolic
formulations.
Subp. 3.
Record keeping.
The generator must maintain the following records documenting
the cleaning and replacement as part of the facility's operating record:
A. the name and address of the
facility;
B. formulations
previously used and the date on which their use ceased in each process at the
plant;
C. formulations currently
used in each process at the plant;
D. the equipment cleaning or replacement
plan;
E. the name and address of
any persons who conducted the cleaning and replacement;
F. the dates on which cleaning and
replacement were accomplished;
G.
the dates of sampling and testing;
H. a description of the sample handling and
preparation techniques, including techniques used for extraction,
containerization, preservation, and chain-of-custody for the samples;
I. a description of the tests performed, the
dates the tests were performed, and the results of the tests;
J. the name and model numbers of the
instruments used in performing the tests;
K. quality assurance/quality control (QA/QC)
documentation; and
L. 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 Minnesota Rules, part
7045.0145, 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."
