NR 665.0401(2)(2) Hazardous wastes or treatment reagents may not be placed in the treatment process or equipment if they could cause the treatment process or equipment to rupture, leak, corrode or otherwise fail before the end of its intended life.

NR 665.0401(3)(3) Where hazardous waste is continuously fed into a treatment process or equipment, the process or equipment shall be equipped with a means to stop this inflow (e.g., a waste feed cut-off system or by-pass system to a standby containment device).

NR 665.0402NR 665.0402 Waste analysis and trial tests. In addition to the waste analysis required by s. NR 665.0013, whenever a hazardous waste which is substantially different from waste previously treated in a treatment process or equipment at the facility is to be treated in that process or equipment, or a substantially different process than any previously used at the facility is to be used to chemically treat hazardous waste, the owner or operator shall do any of the following to show that this proposed treatment will meet all applicable requirements of s. NR 665.0401 (1) and (2), before treating the different waste or using the different process or equipment:

NR 665.0402 NoteNote: Note: As required by s. NR 665.0013, the waste analysis plan shall include analyses needed to comply with ss. NR 665.0405 and 665.0406. As required by s. NR 665.0073, the owner or operator shall place the results from each waste analysis and trial test, or the documented information, in the operating record of the facility.

NR 665.0403NR 665.0403 Inspections. The owner or operator of a treatment facility shall inspect all of the following, where present:

NR 665.0403(1)(1) Discharge control and safety equipment (e.g., waste feed cut-off systems, by-pass systems, drainage systems and pressure relief systems) at least once each operating day, to ensure that it is in good working order.

NR 665.0403(2)(2) Data gathered from monitoring equipment (e.g., pressure and temperature gauges), at least once each operating day, to ensure that the treatment process or equipment is being operated according to its design.

NR 665.0403(3)(3) The construction materials of the treatment process or equipment, at least weekly, to detect corrosion or leaking of fixtures or seams.

NR 665.0403(4)(4) The construction materials of, and the area immediately surrounding, discharge confinement structures (e.g., dikes), at least weekly, to detect erosion or obvious signs of leakage (e.g., wet spots or dead vegetation).

NR 665.0403 NoteNote: As required by s. NR 665.0015(3), the owner or operator shall remedy any deterioration or malfunction the owner or operator finds.

NR 665.0404NR 665.0404 Closure. At closure, all hazardous waste and hazardous waste residues shall be removed from treatment processes or equipment, discharge control equipment and discharge confinement structures.

NR 665.0404 NoteNote: At closure, as throughout the operating period, unless the owner or operator can demonstrate, in accordance with s. NR 661.0003 (3) or (4), that any solid waste removed from the treatment process or equipment is not a hazardous waste, the owner or operator becomes a generator of hazardous waste and shall manage it in accordance with all applicable requirements of chs. NR 662 and 663 and this chapter.

NR 665.0405NR 665.0405 Special requirements for ignitable or reactive waste. Ignitable or reactive waste may not be placed in a treatment process or equipment unless the requirements in sub. (1) or (2) are met:

NR 665.0405(1)(1) The waste is treated, rendered or mixed before or immediately after placement in the treatment process or equipment so that both of the following conditions are met:

NR 665.0405(1)(a)(a) The resulting waste, mixture or dissolution of material no longer meets the definition of ignitable or reactive waste under s. NR 661.0021 or 661.0023.

NR 665.0405(2)(2) The waste is treated in such a way that it is protected from any material or conditions which may cause the waste to ignite or react.

NR 665.0406NR 665.0406 Special requirements for incompatible wastes.

NR 665.0406(1)(1) Incompatible wastes, or incompatible wastes and materials, (see ch. NR 665 Appendix V for examples) may not be placed in the same treatment process or equipment, unless s. NR 665.0017 (2) is complied with.
