Wastes from wood preserving processes at plants that do not resume or initiate
use of chlorophenolic preservatives will not meet the listing definition of

(3) of this section. These wastes may, however, continue to meet another
dangerous waste listing description or may exhibit one or more of the dangerous
waste characteristics.
(2)
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 dangerous waste or constituents, leachate,
contaminated drippage, or dangerous waste decomposition products to the
groundwater, surface water, or atmosphere.
(a) Generators will do one of the following:
(i) Prepare and follow an equipment cleaning
plan and clean equipment in accordance with this section;
(ii) Prepare and follow an equipment
replacement plan and replace equipment in accordance with this section;
or
(iii) Document cleaning and
replacement in accordance with this section, carried out after termination of
use of chlorophenolic preservatives.
(b) Cleaning requirements.
(i) Prepare and sign a written equipment
cleaning plan that describes:
(A) The
equipment to be cleaned;
(B) How
the equipment will be cleaned;
(C)
The solvent to be used in cleaning;
(D) How solvent rinses will be tested;
and
(E) How cleaning residues will
be disposed.
(ii)
Equipment must be cleaned as follows:
(A)
Remove all visible residues from process equipment;
(B) Rinse process equipment with an
appropriate solvent until dioxins and dibenzofurans are not detected in the
final solvent rinse.
(iii) Analytical requirements.
(A) Rinses must be tested in accordance with
SW-846, Method 8290 as incorporated by reference at WAC
173-303-110(3)(a).
(B) "Not detected" means at or below the
lower method calibration limit (MCL) in accordance with SW-846, Method 8290,
Table 1 as incorporated by reference at WAC
173-303-110(3)(a).
(iv) The generator must manage all
residues from the cleaning process as F032 waste.
(c) Replacement requirements.
(i) Prepare and sign a written equipment
replacement plan that describes:
(A) The
equipment to be replaced;
(B) How
the equipment will be replaced; and
(C) How the equipment will be
disposed.
(ii) The
generator must manage the discarded equipment as F032 waste.
(d) Documentation requirements.
Document that previous equipment cleaning and/or replacement was performed in
accordance with this section and occurred after cessation of use of
chlorophenolic preservatives.
(3) 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 of the samples;
(i) A description of the tests performed, the
date the tests were performed, and the results of the tests;
(j) The name and model numbers of the
instrument(s) used in performing the tests;
(k) QA/QC documentation; and
(l) The following statement signed by the
generator or his authorized representative: I certify under penalty of law that
all process equipment required to be cleaned or replaced under WAC
173-303-083 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
