				Procedures for Demonstrating That Dyes or Pigments Nonwastewaters Are Not K181
				Waste. The procedures described in subsections (d)(1) through (d)(3) and (d)(5)
				establish when nonwastewaters from the production of dyes or pigments would not
				be hazardous. (These procedures apply to wastes that are not disposed of in
				landfill units or treated in combustion units, as specified in subsection (a)).
				If the nonwastewaters are disposed of in landfill units or treated in
				combustion units as described in subsection (a), then the nonwastewaters are
				not hazardous. In order to demonstrate that it is meeting the landfill disposal
				or combustion conditions contained in the K181 waste listing description, the
				generator must maintain documentation as described in subsection (d)(4).
1) Determination Based on No K181 Waste
				Constituents. A generator that has knowledge (e.g., knowledge of constituents
				in wastes based on prior sampling and analysis data or information about raw
				materials used, production processes used, and reaction and degradation
				products formed) that its waste contains none of the K181 waste constituents
				(see subsection (c)) can use its knowledge to determine that its waste is not
				K181 waste. The generator must document the basis for all such determinations
				on an annual basis and keep each annual documentation for three
				years.
2) Determination for
				Generated Quantities of 1,000 Tonnes (1,000 Metric Tons) Per Year or Less for
				Wastes That Contain K181 Waste Constituents. If the total annual quantity of
				dyes or pigments nonwastewaters generated is 1,000 tonnes or less, the
				generator can use knowledge of the wastes (e.g., knowledge of constituents in
				wastes based on prior analytical data 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 (c). To make this determination, the generator
				must fulfill the following conditions:
A) Each
				year, the generator must document the basis for determining that the annual
				quantity of nonwastewaters expected to be generated will be less than 1,000
				tonnes;
B) The generator must track
				the actual quantity of nonwastewaters generated from January 1 through December
				31 of each calendar year. If, at any time within the year, the actual waste
				quantity exceeds 1,000 tonnes, the generator must comply with the requirements
				of subsection (d)(3) for the remainder of that calendar year;
C) The generator must keep a running total of
				the K181 waste constituent mass loadings over the course of the calendar year;
				and
D) The generator must keep the
				following records on site for the three most recent calendar years in which the
				hazardous waste determinations were made:
i)
				The quantity of dyes or pigments nonwastewaters generated;
ii) The relevant process information used;
				and
iii) The calculations performed
				to determine annual total mass loadings for each K181 waste constituent in the
				nonwastewaters during the year.
3) Determination for generated quantities
				greater than 1,000 tonnes per year for wastes that contain K181 constituents.
				If the total annual quantity of dyes or pigments nonwastewaters generated is
				greater than 1,000 tonnes, the generator must perform each of the following
				steps in order to make a determination that its waste is not K181 waste:
A) The generator must determine which K181
				waste constituents (see subsection (c)) are reasonably expected to be present
				in the wastes based on knowledge of the wastes (e.g., based on prior sampling
				and analysis data or information about raw materials used, production processes
				used, and reaction and degradation products formed);
B) If 1,2-phenylenediamine is present in the
				wastes, the generator can use either knowledge of the wastes or sampling and
				analysis procedures to determine the level of this constituent in the wastes.
				For determinations based on use of knowledge of the wastes, the generator must
				comply with the procedures for using knowledge of the wastes described in
				subsection (d)(2) and keep the records described in subsection (d)(2)(D). For
				determinations based on sampling and analysis, the generator must comply with
				the sampling and analysis and recordkeeping requirements described in
				subsection (d)(3)(C);
C) The
				generator must develop a waste sampling and analysis plan (or modify an
				existing plan) to collect and analyze representative waste samples for the K181
				waste constituents reasonably expected to be present in the wastes. At a
				minimum, the plan must include the following elements:
i) A discussion of the number of samples
				needed to characterize the wastes fully;
ii) The planned sample collection method to
				obtain representative waste samples;
iii) A discussion of how the sampling plan
				accounts for potential temporal and spatial variability of the wastes;
				and
iv) A detailed description of
				the test methods to be used, including sample preparation, clean up (if
				necessary), and determinative methods;
D) The generator must collect and analyze
				samples in accordance with the waste sampling and analysis plan, and the plan
				must fulfill the following requirements:
i)
				The sampling and analysis must be unbiased, precise, and representative of the
				wastes; and
ii) 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 (c);
E) The
				generator must record the analytical results;
F) The generator must record the waste
				quantity represented by the sampling and analysis results;
G) The genrator must calculate
				constituent-specific mass loadings (product of concentrations and waste
				quantity);
H) The generator must
				keep a running total of the K181 waste constituent mass loadings over the
				course of the calendar year;
I) The
				generator must determine whether the mass of any of the K181 waste constituents
				listed in subsection (c) generated between January 1 and December 31 of any
				calendar year is below the K181 waste listing levels;
J) The generator must keep the following
				records on site for the three most recent calendar years in which the hazardous
				waste determinations are made:
i) The
				sampling and analysis plan;
ii) The
				sampling and analysis results (including quality assurance or quality control
				data);
iii) The quantity of dyes or
				pigments nonwastewaters generated; and
iv) The calculations performed to determine
				annual mass loadings; and
K) The generator must conduct non-hazardous
				waste determinations annually to verify that the wastes remain non-hazardous.
i) The annual testing requirements are
				suspended after three consecutive successful annual demonstrations that the
				wastes are non-hazardous. The generator can then use knowledge of the wastes to
				support subsequent annual determinations.
ii) 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.
iii) If the annual testing requirements are
				suspended, the generator must keep records of the process knowledge information
				used to support a non-hazardous determination. If testing is reinstated, the
				generator must retain a description of the process change.
4) Recordkeeping for the Landfill
				Disposal and Combustion Exemptions. For the purposes of meeting the landfill
				disposal and combustion condition set out in the K181 waste listing description
				in subsection (a), 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 which meets the landfill design standards
				set out in the listing description or that the waste was treated in combustion
				units, as specified in the listing description in subsection (a).
5) Waste Holding and Handling. During the
				interim period, from the point of generation to completion of the hazardous
				waste determination, the generator must store the wastes appropriately. If the
				wastes are determined to be hazardous and the generator has not complied with
				the hazardous waste storage requirements of 35 Ill. Adm. Code 722.116 during
				the interim period, the generator could be subject to an enforcement action for
				improper hazardous waste management.
