3If o-, m-, and p-Cresol concentrations cannot be differentiated, the total cresol, D026, concentration is used. The regulatory level of total cresol is 200 mg/l.
4Quantitation limit is greater than the calculated regulatory level. The quantitation limit therefore becomes the regulatory level.

NR 661.0032(4)(a)
(a)
Determination based on no K181 constituents. A generator that has knowledge, such as 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 wastes contain none of the K181 constituents listed in sub

NR 661.0032(4)(c)2.
2. 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 shall comply with the procedures for using knowledge described in par.

a. The annual testing requirements are suspended after 3 consecutive successful annual demonstrations that the wastes are nonhazardous. The generator can then use knowledge of the wastes to support subsequent annual determinations.
NR 661.0032(4)(c)11.b.
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.
NR 661.0032(4)(c)11.c.
c. If the annual testing requirements are suspended, the generator shall keep records of the process knowledge information used to support a nonhazardous determination. If testing is reinstated, a description of the process change shall be retained.

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 requirements during the interim period, the generator may be subject to an enforcement action for improper management.

An example of a legitimate re-use of the residue would be where the residue remains in the container and the container is used to hold the same commercial chemical product or manufacturing chemical intermediate it previously held. An example of the discard of the residue would be where the drum is sent to a drum reconditioner who reconditions the drum but discards the residue.
