NR 661.0004(2)(n)(n) Used oil re-refining distillation bottoms that are used as feedstock to manufacture asphalt products. NR 661.0004(2)(o)(o) Leachate or gas condensate collected from landfills where certain solid wastes have been disposed, provided that all of the following are met: NR 661.0004(2)(o)1.1. The solid wastes disposed would meet one or more of the listing descriptions for hazardous waste codes K169, K170, K171, K172, K174, K175, K176, K177, K178, and K181 if these wastes had been generated after the effective date of the listing. NR 661.0004(2)(o)2.2. The solid wastes described in subd. 1. were disposed prior to the effective date of the listing. NR 661.0004(2)(o)3.3. The leachate or gas condensate do not exhibit any characteristic of hazardous waste nor are derived from any other listed hazardous waste. NR 661.0004(2)(o)4.4. Discharge of the leachate or gas condensate, including leachate or gas condensate transferred from the landfill to a POTW by truck, rail, or dedicated pipe, is subject to regulation under ch. 283, Stats., or 33 USC 1317 (b) or 1342. NR 661.0004(2)(o)5.5. As of February 13, 2001, leachate or gas condensate derived from K169 to K172 is no longer exempt if it is stored or managed in a surface impoundment prior to discharge. As of November 21, 2003, leachate or gas condensate derived from K176, K177, and K178 is no longer exempt if it is stored or managed in a surface impoundment prior to discharge. After February 26, 2007, leachate or gas condensate derived from K181 will no longer be exempt if it is stored or managed in a surface impoundment prior to discharge. One exception to these requirements is the following: if the surface impoundment is used to temporarily store leachate or gas condensate in response to an emergency situation, such as shutdown of wastewater treatment system, provided the impoundment has a double liner, and provided the leachate or gas condensate is removed from the impoundment and continues to be managed in compliance with the conditions of this subdivision after the emergency ends. NR 661.0004(2)(r)(r) Solvent-contaminated wipes, except for wipes that are hazardous waste due to the presence of trichloroethylene, that are sent for disposal are not hazardous wastes from the point of generation provided all of the following are met: NR 661.0004(2)(r)1.1. The solvent-contaminated wipes, when accumulated, stored, and transported, are contained in non-leaking, closed containers that are labeled “Excluded Solvent-Contaminated Wipes.” The containers shall be able to contain free liquids, should free liquids occur. During accumulation, a container is considered closed when there is complete contact between the fitted lid and the rim, except when it is necessary to add or remove solvent-contaminated wipes. When the container is full, or when the solvent-contaminated wipes are no longer being accumulated, or when the container is being transported, the container shall be sealed with all lids properly and securely affixed to the container and all openings tightly bound or closed sufficiently to prevent leaks and emissions. NR 661.0004(2)(r)2.2. The solvent-contaminated wipes may be accumulated by the generator for up to 180 days from the start date of accumulation for each container prior to being sent for disposal. NR 661.0004(2)(r)4.4. Free liquids removed from the solvent-contaminated wipes or from the container holding the wipes shall be managed according to the applicable regulations under chs. NR 660 to 667. NR 661.0004(2)(r)5.5. A generator shall maintain at its site all of the following documentation: NR 661.0004(2)(r)5.a.a. Name and address of the landfill or combustor that is receiving the solvent-contaminated wipes. NR 661.0004(2)(r)5.c.c. Description of the process the generator is using to ensure solvent-contaminated wipes contain no free liquids at the point of being transported for disposal. NR 661.0004(2)(r)6.6. The solvent-contaminated wipes are sent for disposal to any of the following: NR 661.0004(3)(3) Hazardous Wastes That Are Exempted From Certain Regulations. A hazardous waste generated in a product or raw material storage tank, a product or raw material transport vehicle or vessel, a product or raw material pipeline, or in a manufacturing process unit or an associated non-waste-treatment-manufacturing unit, is not subject to regulation under chs. NR 662 to 665, 668, and 670 or to the notification requirements specified in s. NR 660.07 until it exits the unit in which it was generated, unless the unit is a surface impoundment, or unless the hazardous waste remains in the unit more than 90 days after the unit ceases to be operated for manufacturing, or for storage or transportation of product or raw materials. NR 661.0004(4)(a)(a) Except as provided in pars. (b) and (d), a sample of solid waste or a sample of water, soil, or air collected for the sole purpose of testing to determine its characteristics or composition is not subject to any requirements under this chapter or chs. NR 662 to 670 or to the notification requirements under s. NR 660.07, when one of the following occurs: NR 661.0004(4)(a)1.1. The sample is being transported to a laboratory for the purpose of testing. NR 661.0004(4)(a)2.2. The sample is being transported back to the sample collector after testing. NR 661.0004(4)(a)3.3. The sample is being stored by the sample collector before transport to a laboratory for testing. NR 661.0004(4)(a)5.5. The sample is being stored in a laboratory after testing but before it is returned to the sample collector.
