PART 261_IDENTIFICATION AND LISTING OF HAZARDOUS WASTE--Table of Contents
 
                   Subpart D_Lists of Hazardous Wastes
 
Sec.  261.35  Deletion of certain hazardous waste codes following 
equipment cleaning and replacement.

    (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 paragraphs (b) and (c) of this section. 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,

[[Page 85]]

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 ground water, surface water, or 
atmosphere.
    (1) Generators shall 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 
preservations.
    (2) 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 by using an appropriate method.
    (B) ``Not detected'' means at or below the following lower method 
calibration limits (MCLs): The 2,3,7,8-TCDD-based MCL--0.01 parts per 
trillion (ppt), sample weight of 1000 g, IS spiking level of 1 ppt, 
final extraction volume of 10-50 [mu]L. For other congeners--multiply 
the values by 1 for TCDF/PeCDD/PeCDF, by 2.5 for HxCDD/HxCDF/HpCDD/
HpCDF, and by 5 for OCDD/OCDF.
    (iv) The generator must manage all residues from the cleaning 
process as F032 waste.
    (3) 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.
    (4) Documentation requirements.
    (i) Document that previous equipment cleaning and/or replacement was 
performed in accordance with this section and 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, 
including 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 instrument(s) used in 
performing the tests;
    (11) QA/QC documentation; and
    (12) 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 40 CFR 261.35 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.
