NR 716.09(3)(a)(a) The department may instruct responsible parties to proceed without departmental review of work plans submitted under this section. NR 716.09(3)(b)(b) Responsible parties that are not instructed to proceed under par. (a) shall wait before initiating the field investigation until the department has approved or conditionally approved the work plan, except that if the department has not reviewed the work plan within 30 days after its receipt by the department, the responsible parties shall proceed with the field investigation. NR 716.09(3)(c)(c) If the department disapproves a work plan submitted under this section, the department shall provide to the responsible parties, in writing, the basis for disapproval and a deadline for providing a revised work plan. NR 716.09(3)(d)(d) The lack of a response from the department, after the department’s receipt of a work plan, may not be construed to mean that the department has approved the work plan.

NR 716.09 HistoryHistory: Cr. Register, April, 1994, No. 460, eff. 5-1-94; r. and recr. (1), r. (3) (e), Register, April, 1995, No. 472, eff. 5-1-95; CR 12-023: am. (1), (2) (a), (f) 3., 5., 8., (g), (3) (b) Register October No. 694, eff. 11-1-13. NR 716.11(1)(1) Responsible parties shall conduct a field investigation as part of each site investigation required under this chapter, unless the department directs otherwise. NR 716.11(2)(2) The field investigation shall be conducted in accordance with a work plan approved or conditionally approved by the department, unless the department has directed the responsible parties to proceed with a field investigation without department review of the investigation work plan. NR 716.11(2g)(2g) The field investigation shall be initiated within 90 days of submittal of the work plan. NR 716.11(2r)(2r) In cases where the responsible party pays a fee for department review of the work plan, the field investigation shall be initiated within 60 days after department approval of the work plan. NR 716.11 NoteNote: The intent of this subsection is to be able to measure that progress is being made toward conducting a site investigation. Initiation may include preparatory measures to conducting the actual fieldwork.
NR 716.11(3)(3) The purposes of the field investigation shall be to: NR 716.11(3)(a)(a) Determine the nature, degree and extent, both areal and vertical, of the hazardous substances or environmental pollution in all affected media. NR 716.11(3)(b)(b) Provide sufficient information to permit evaluation of interim options pursuant to ch. NR 708, and remedial action options pursuant to ch. NR 722, and to permit a determination to be made regarding whether any of the interim or remedial action options require a treatability study or other pilot-scale study. NR 716.11(3)(c)(c) Provide sufficient information to determine the hydraulic conductivity of materials where contaminated groundwater is found. NR 716.11(3)(d)(d) Provide an estimate, along with all necessary supporting information, of the mass of contamination in the source area. This includes sites involving free product or where natural attenuation is considered for part of the remedy. NR 716.11 NoteNote: The intent of this paragraph is to address situations where a discrete area indicates a release of a hazardous substance. It is not intended for situations where there is no discrete source area, such as when there is area-wide contamination from aerial deposition, or widespread areas of fill such as foundry ash.
NR 716.11(4)(4) Responsible parties shall extend the field investigation beyond the property boundaries of the source area as necessary to fully define the extent of the contamination. If the responsible parties are unable to complete the required investigation beyond the source property because a property owner refuses access, the responsible parties shall notify the department within 30 days of the refusal, and shall document in writing the efforts undertaken to gain access when requested by the department. NR 716.11(5)(5) The field investigation shall include an evaluation of all of the following items: NR 716.11(5)(a)(a) Potential pathways for migration of the contamination, including drainage improvements, utility corridors, bedrock and permeable material or soil along which vapors, free product or contaminated water may flow.
