(c) It is a mixture of a
waste and 1 or more hazardous wastes that are listed in
R 299.9213 or
R 299.9214 and has not been excluded from this subdivision pursuant to
R 299.9211 or subrule (7) or (8) of this rule; however, mixtures of wastes and hazardous wastes that are listed in
R 299.9213 and
R 299.9214 are not hazardous wastes, except by
application of subdivision (a) or (b) of this subrule, if the
generator can demonstrate that the mixture consists of
wastewater which, with respect to
discharge, is subject to regulation pursuant to either section 402 or section 307(b) of the
federal clean water act, including
wastewater at facilities that have eliminated the
discharge of
wastewater, and is 1 of the following:
(i) One or more of the following spent solvents that are listed in
R 299.9213, if the maximum total weekly usage of the solvents, other than the amounts that can be demonstrated not to be discharged to
wastewater, divided by the average weekly flow of
wastewater into the headworks of
the facility's
wastewater treatment or pretreatment
system is not more than 1 part per million or the total measured concentration of these solvents entering the headworks of
the facility's astewater
treatment system, at facilities subject to regulation under parts 60, 61, or 63 of the
federal clean air act or at facilities subject to an enforceable limit in a federal operating
permit that minizmizes
fugitive emissions, is not more than 1 part per million on an average weekly basis:
(A) Carbon tetrachloride.
(B) Tetrachloroethylene.
(C) Trichloroethylene.
(D) Benzene.

Any facility that uses benzene as a solvent and claims this exemption shall use an aerated biological wastewater treatment system and only lined surface impoundments or tanks before secondary clarification in the wastewater treatment system. Facilities that choose to measure concentration levels shall file a copy of their sampling and analysis plan with the director. A facility shall file a revised sampling and analysis plan if the initial plan is rendered inaccurate by changes in the facility's operations. The sampling and analysis plan shall include the monitoring point location at the headworks, the sampling frequency and methodology, and a list of constituents to be monitored. A facility shall be eligible for the direct monitoring option once it receives confirmation that the sampling and analysis plan has been received by the director. The director may reject the sampling and analysis plan if he or she finds that the sampling and analysis plan does not include the required information or the plan parameters do not enable the facility to calculate the weekly average concentration of these chemicals accurately. If the director rejects the sampling and analysis plan or finds that the facility is not following the sampling and analysis plan, he or she shall notify the facility that it must cease the use of the direct monitoring option until the bases for the rejection are corrected.
(ii) One or more of the following spent solvents that are listed in
R 299.9213, if the maximum total weekly usage of the solvents, other than the amounts that can be demonstrated not to be discharged to
wastewater, divided by the average weekly flow of
wastewater into the headworks of
the facility's
wastewater treatment or pretreatment
system is not more than 25 parts per million or the total measured concentration of these solvents entering the headworks of
the facility's
wastewater treatment system, at facilities subject to regulation under part 60, 61, or 63 of the
federal clean air act or at facilities subject to an enforceable limit in a federal operating
permit that minizmizes
fugitive emissions, is not more than 25 parts per million on an average weekly basis:
(A) Methylene chloride.
(B) 1,1,1-Trichloroethane.
(C) Chlorobenzene.
(D) o-dichlorobenzene.

Facilities that choose to measure concentration levels shall file a copy of their sampling and analysis plan with the director. A facility shall file a revised sampling and analysis plan if the initial plan is rendered inaccurate by changes in the facility's operations. The sampling and analysis plan shall include the monitoring point location at the headworks, the sampling frequency and methodology, and a list of constituents to be monitored. A facility shall be eligible for the direct monitoring option once they receive confirmation that the sampling and analysis plan has been received by the director. The director may reject the sampling and analysis plan if he or she finds that the sampling and analysis plan does not include the required information or the plan parameters do not enable the facility to calculate the weekly average concentration of these chemicals accurately. If the director rejects the sampling and analysis plan or finds that the facility is not following the sampling and analysis plan, he or she shall notify the facility that it must cease the use of the direct monitoring option until the bases for the rejection are corrected.

wastewater is not more than 1% of total
wastewater flow into the headworks of
the facility's
wastewater treatment or pretreatment
system or if the wastes' combined annualized average concentration is not more than 1 part per million in the headworks of
the facility's
wastewater treatment or pretreatment
facility. Toxic (T) wastes which are used in laboratories and which are demonstrated not to be discharged to
wastewater shall not be included in the calculation.
(vi) Wastewater from the production of carbamates and carbamoyl oximes, K157, if the maximum weekly usage of formaldehyde, methyl chloride, methylene chloride, and triethylamine, including all amounts that cannot be demonstrated to be reacted in the process, destroyed through treatment, or recovered, divided by the average weekly flow of process wastewater before any dilutions into the headworks of the facility's wastewater treatment system is not more than a total of 5 parts per million by weight or the total measured concentration of these chemicals entering the headworks of the facility's wastewater treatment system is not more than 5 parts per million on an average weekly basis.

The director may reject the sampling and analysis plan if he or she finds that the sampling and analysis plan does not include the required information or the plan parameters do not enable the facility to calculate the weekly average concentration of these chemicals accurately. If the director rejects the sampling and analysis plan or finds that the facility is not following the sampling and analysis plan, he or she shall notify the facility that it must cease the use of the direct monitoring option until the bases for the rejection are corrected.
(vii) Wastewater derived from the treatment of organic waste from the production of carbamates and carbamoyl oximes, K156, if the maximum concentration of formaldehyde, methyl chloride, methylene chloride, and triethylamine before any dilutions into the headworks of the facility's wastewater treatment system is not more than a total of 5 milligrams per liter or the total measured concentration of these chemicals entering the headworks of the facility's wastewater treatment system is not more than 5 milligrams per liter on an average weekly basis. Facilities that choose to measure concentration levels shall file a copy of their sampling and analysis plan with the director. A facility shall file a revised sampling and analysis plan if the initial plan is rendered inaccurate by changes in the facility's operations. The sampling and analysis plan shall include the monitoring point location at the headworks, the sampling frequency and methodology, and a list of constituents to be monitored. A facility shall be eligible for the direct monitoring option once it receives confirmation that the sampling and analysis plan has been received by the director. The director may reject the sampling and analysis plan if he or she finds that the sampling and analysis plan does not include the required information or the plan parameters do not enable the facility to calculate the weekly average concentration of these chemicals accurately.

(e) It is a
used oil that contains more than 1,000 parts per million total halogens.
Used oil that contains more than 1,000 parts per million is presumed to be a
hazardous waste and is regulated as such under
part 111 of the
act and these rules. A
person may rebut the presumption by demonstrating that the
used oil does not contain
hazardous waste. The demonstration may be made by showing that the
used oil does not contain
significant concentrations of halogenated hazardous constituents that are listed in 40 C.F.R. part
261, appendix VIII. The rebuttable presumption rule does not apply to the following materials:
(i) Metalworking oils or fluids that contain chlorinated paraffins if the oils or fluids are processed through a tolling
agreement as specified in 40 C.F.R. §
279.24(c) to reclaim the oils or fluids. The rebuttable presumption does apply, however, if the oils or fluids are recycled in any other manner or are disposed of.
(ii) Used oils that are contaminated with chlorofluorocarbons which have been removed from refrigeration units if the chlorofluorocarbons are destined for reclamation. The rebuttable presumption does apply, however, if the used oils are contaminated with chlorofluorocarbons that have been mixed with used oil from sources other than refrigeration units.
