Listing Specific Definitions:
a
For the purposes of the F037 and F038 listings,
						oil/water/solids is defined as oil and/or water and/or solids.
b(i)
For the purposes of the F037 and F038 listings, aggressive
						biological treatment units are defined as units which employ one of the
						following four treatment methods: Activated sludge; trickling filter; rotating
						biological contactor for the continuous accelerated biological oxidation of
						wastewaters; or high-rate aeration. High-rate aeration is a system of surface

						(B) the hydraulic retention time of the unit is no longer than 5 days; or (C)
						the hydraulic retention time is no longer than 30 days and the unit does not
						generate a sludge that is a dangerous waste by the Toxicity Characteristic.
(ii)
Generators and treatment, storage and disposal facilities
						have the burden of proving that their sludges are exempt from listing as F037
						and F038 wastes under this definition. Generators and treatment, storage and
						disposal facilities must maintain, in their operating or other on-site records,
						documents and data sufficient to prove that: (A) The unit is an aggressive
						biological treatment unit as defined in this subsection; and (B) the sludges
						sought to be exempted from the definitions of F037 and/or F038 were actually
						treated in the aggressive biological treatment unit.
c(i)
For the purposes of the F037 listing, sludges are
						considered to be generated at the moment of deposition in the unit, where
						deposition is defined as at least a temporary cessation of lateral particle
						movement.
(ii)
For the purposes of the F038 listing,
(A)
Sludges are considered to be generated at the moment of
						deposition in the unit, where deposition is defined as at least a temporary
						cessation of lateral particle movement and

Procedures for demonstrating that dyes and/or
						pigment nonwastewaters are not K181
. The procedures described in (a)
						through (c) and (e) of this subsection establish when nonwastewaters from the
						production of dyes/pigments would not be hazardous (these procedures apply to
						wastes that are not disposed in landfill units or treated in combustion units
						as specified in subsection (1) - the K181 listing - of this section). If the
						nonwastewaters are disposed in landfill units or treated in combustion units as
						described in subsection (1) of this section, then the non-wastewaters are not
						hazardous. In order to demonstrate that it is meeting the landfill disposal or
						combustion conditions contained in the K181 listing description, the generator
						must maintain documentation as described in (d) of this subsection.
(a)
Determination based on no K181
						constituents
. Generators that have knowledge (for example, knowledge
						of constituents in wastes based on prior sampling and analysis data and/or
						information about raw materials used, production processes used, and reaction
						and degradation products formed) that their wastes contain none of the K181
						constituents (
see
subsection (3) of this section) can use
						their knowledge to determine that their waste is not K181. The generator must
						document the basis for all such determinations on an annual basis and keep each
						annual documentation for three years.
(b)
Determination for generated quantities of 1,000
						MT/yr or less for wastes that contain K181 constituents
. If the total
						annual quantity of dyes and/or pigment nonwastewaters generated is 1,000 metric
						tons or less, the generator can use knowledge of the wastes (for example,
						knowledge of constituents in wastes based on prior analytical data and/or
						information about raw materials used, production processes used, and reaction
						and degradation products formed) to conclude that annual mass loadings for the
						K181 constituents are below the listing levels of subsection (3) of this
						section. To make this determination, the generator must:
(i)
Each year document the basis for determining that the
						annual quantity of nonwastewaters expected to be generated will be less than
						1,000 metric tons.
(ii)
Track the actual quantity of nonwastewaters generated from
						January 1 through December 31 of each year. If, at any time within the year,
						the actual waste quantity exceeds 1,000 metric tons, the generator must comply
						with the requirements of (c) of this subsection for the remainder of the year.
(iii)
Keep a running total of the K181 constituent mass loadings
						over the course of the calendar year.
(iv)
Keep the following records on-site for the three most
						recent calendar years in which the hazardous waste determinations are made:
(A)
The quantity of dyes and/or pigment non-wastewaters
						generated.
(B)
The relevant process information used.
(C)
The calculations performed to determine annual total mass
						loadings for each K181 constituent in the nonwastewaters during the year.
(c)
Determination for generated quantities greater
						than 1,000 MT/yr for wastes that contain K181 constituents
. If the
						total annual quantity of dyes and/or pigment nonwaste-waters generated is
						greater than 1,000 metric tons, the generator must perform all of the steps
						described in (c)(i) through (xi) of this subsection in order to make a
						determination that its waste is not K181.
(i)
Determine which K181 constituents (see subsection (3) of
						this section) are reasonably expected to be present in the wastes based on
						knowledge of the wastes (for example, based on prior sampling and analysis data
						and/or information about raw materials used, production processes used, and
						reaction and degradation products formed).
(ii)
If 1,2-phenylenediamine is present in the wastes, the
						generator can use either knowledge or sampling and analysis procedures to
						determine the level of this constituent in the wastes. For determinations based
						on use of knowledge, the generator must comply with the procedures for using
						knowledge described in (b) of this subsection and keep the records described in
						(b)(iv) of this subsection. For determinations based on sampling and analysis,
						the generator must comply with the sampling and analysis and recordkeeping
						requirements described below in this subsection.
(iii)
Develop a waste sampling and analysis plan (or modify an
						existing plan) to collect and analyze representative waste samples for the K181
						constituents reasonably expected to be present in the wastes. At a minimum, the
						plan must include:
(A)
A discussion of the number of samples needed to
						characterize the wastes fully;
(B)
The planned sample collection method to obtain
						representative waste samples;
(C)
A discussion of how the sampling plan accounts for
						potential temporal and spatial variability of the wastes;
(D)
A detailed description of the test methods to be used,
						including sample preparation, clean up (if necessary), and determinative
						methods.
(iv)
Collect and analyze samples in accordance with the waste
						sampling and analysis plan.
(A)
The sampling and analysis must be unbiased, precise, and
						representative of the wastes;
(B)
The analytical measurements must be sufficiently
						sensitive, accurate and precise to support any claim that the constituent mass
						loadings are below the listing levels of subsection (3) of this section.
(v)
Record the analytical results.
(vi)
Record the waste quantity represented by the sampling and
						analysis results.
(vii)
Calculate constituent-specific mass loadings (product of
						concentrations and waste quantity).
(viii)
Keep a running total of the K181 constituent mass loadings
						over the course of the calendar year.
(ix)
Determine whether the mass of any of the K181 constituents
						listed in subsection (3) of this section generated between January 1 and
						December 31 of any year is below the K181 listing levels.
(x)
Keep the following records on-site for the three most
						recent calendar years in which the hazardous waste determinations are made:
(A)
The sampling and analysis plan.
(B)
The sampling and analysis results (including QA/QC data).
(C)
The quantity of dyes and/or pigment non-wastewaters
						generated.
(D)
The calculations performed to determine annual mass
						loadings.
(xi)
Nonhazardous waste determinations must be conducted
						annually to verify that the wastes remain nonhazardous.
(A)
The annual testing requirements are suspended after three
						consecutive successful annual demonstrations that the wastes are nonhazardous.
						The generator can then use knowledge of the wastes to support subsequent annual
						determinations.
(B)
The annual testing requirements are reinstated if the
						manufacturing or waste treatment processes generating the wastes are
						significantly altered, resulting in an increase of the potential for the wastes
						to exceed the listing levels.
(C)
If the annual testing requirements are suspended, the
						generator must keep records of the process knowledge information used to
						support a nonhazardous determination. If testing is reinstated, a description
						of the process change must be retained.
(d)
Recordkeeping for the landfill disposal and
						combustion exemptions.
For the purposes of meeting the landfill
						disposal and combustion condition set out in the K181 listing description, the
						generator must maintain on-site for three years documentation demonstrating
						that each shipment of waste was received by a landfill unit that is subject to
						or meets the landfill design standards set out in the listing description, or
						was treated in combustion units as specified in the listing description.
(e)
Waste holding and handling
. During the
						interim period, from the point of generation to completion of the hazardous
						waste determination, the generator is responsible for storing the wastes
						appropriately. If the wastes are determined to be hazardous and the generator
						has not complied with the Hazardous Waste Management Act and the dangerous
						waste regulation requirements during the interim period, the generator could be
						subject to an enforcement action for improper management.
