d) 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.
