Potential for exposure of humans and environmental receptors if releases were to occur from the CAMU. NR 664.0551(5)(d)4.4. Long-term care requirements as necessary to protect human health and the environment, to include, for areas where wastes will remain in place, monitoring and maintenance activities and the frequency with which the activities shall be performed to ensure the integrity of any cap, final cover or other containment system. NR 664.0551(6)(6) The department shall document the rationale for designating CAMUs and shall make the documentation available to the public. NR 664.0551(7)(7) Incorporation of a CAMU into an existing license shall be approved by the department according to the procedures for department-initiated license modifications under s. NR 670.041, or according to the license modification procedures of s. NR 670.042. NR 664.0551(8)(8) The designation of a CAMU does not change the department’s existing authority to address clean-up levels, media-specific points of compliance to be applied to remediation at a facility or other remedy selection decisions.

NR 664.0552NR 664.0552 Corrective action management units (CAMUs). NR 664.0552(1)(1) To implement remedies under s. NR 664.0101, ss. 291.37 and 291.97 (1), Stats., or 42 USC 6928 (h) or to implement remedies at a licensed facility that is not subject to s. NR 664.0101, the department may designate an area at the facility as a corrective action management unit under the requirements in this section. In this section, “corrective action management unit” or “CAMU” means an area within a facility that is used only for managing CAMU-eligible wastes for implementing corrective action or cleanup at the facility. A CAMU shall be located within the contiguous property under the control of the owner or operator where the wastes to be managed in the CAMU originated. One or more CAMUs may be designated at a facility. NR 664.0552(1)(a)(a) In this section, “CAMU-eligible waste” means all of the following: NR 664.0552(1)(a)1.1. All solid and hazardous wastes, and all media (including groundwater, surface water, soils and sediments) and debris, that are managed for implementing cleanup. As-generated wastes (either hazardous or non-hazardous) from ongoing industrial operations at a site are not CAMU-eligible wastes.
