NR 103.08(2) (2) Wetland functional values and the impact of a proposed activity upon those functional values shall be determined using wetland ecological evaluation methods accepted by the department and appropriate to the affected wetland. The department shall consider available land use studies in its determinations.

NR 103.08(3) (3) To protect all present and prospective future uses of wetlands, the following factors shall be considered by the department in making determinations under this section:

NR 103.08(3)(a) (a) Wetland dependency of the proposal;

NR 103.08(3)(b) (b) Practicable alternatives to the proposal which will avoid and minimize adverse impacts to wetlands and will not result in other significant adverse environmental consequences;

NR 103.08(3)(c) (c) Impacts which may result from the activity on the maintenance, protection, restoration or enhancement of standards under s. NR 103.03;

NR 103.08(3)(d) (d) Cumulative impacts attributable to the proposed activity which may occur, based upon past or reasonably anticipated impacts on wetland functional values of similar activities in the affected area;

NR 103.08(3)(e) (e) Potential secondary impacts on wetland functional values from the proposed activity; and

NR 103.08(3)(f) (f) Any potential adverse impacts to wetlands in areas of special natural resource interest as listed in s. NR 103.04.

NR 103.08(3)(g) (g) Any potential adverse impact to wetlands in environmentally sensitive areas and environmental corridors identified in areawide water quality management plans.

NR 103.08(4) (4) 

NR 103.08(4)(a) (a) Except as provided in par. (b), (c) or (d), the department shall make a finding that the requirements of this chapter are satisfied if it determines that the project proponent has shown all of the following:

NR 103.08(4)(a)1. 1. No practicable alternative exists which would avoid adverse impacts to wetlands.

NR 103.08(4)(a)2. 2. If subd. 1. is met, all practicable measures to minimize adverse impacts to the functional values of the affected wetlands have been taken.

NR 103.08(4)(a)3. 3. If subds. 1. and 2. are met, utilizing the factors in sub. (3) (b) to (g) and considering potential wetland functional values provided by any mitigation project that is part of the subject application, that the activity will not result in significant adverse impacts to wetland functional values, significant adverse impacts to water quality or other significant adverse environmental consequences.

NR 103.08(4)(b) (b) For all activities that will adversely affect a wetland in an area of special natural resource interest as listed in s. NR 103.04 or that will adversely affect an area of special natural resource interest, the department may not consider potential functional values provided by any mitigation project that is part of the subject application.

NR 103.08(4)(c) (c) For all activities which meet one or more of subd. 1., 2. or 3., the department, utilizing the factors in sub. (3) and considering potential wetland functional values provided by any mitigation project that is part of the subject application, shall make a finding that the requirements of this chapter are satisfied if it determines that the project proponent has shown that the activity will not result in significant adverse impacts to wetland functional values, significant adverse impacts to water quality or other significant adverse environmental consequences. The department may limit the scope of the analysis of alternatives under sub. (3) (b), as determined at the preliminary assessment meeting under sub. (1).

NR 103.08(4)(c)1. 1. The activity is wetland dependent.

NR 103.08(4)(c)2. 2. The surface area of the wetland impact, which includes impacts noted in s. NR 103.08 (3), is 0.10 acres or less.

NR 103.08(4)(c)3. 3. All wetlands that may be affected by an activity are less than one acre in size, located outside a 100-year floodplain, and not any of the following types:

NR 103.08(4)(c)3.a. a. Deep marsh.

NR 103.08(4)(c)3.b. b. Ridge and swale complex.

NR 103.08(4)(c)3.c. c. Wet prairie not dominated by reed canary grass (Phalaris arundinacea) to the exclusion of a significant population of native species.

NR 103.08(4)(c)3.d. d. Ephemeral pond in a wooded setting.

NR 103.08(4)(c)3.e. e. Sedge meadow or fresh wet meadow not dominated by reed canary grass (Phalaris arundinacea) to the exclusion of a significant population of native species and located south of highway 10.

NR 103.08(4)(c)3.f. f. Bog located south of highway 10.

NR 103.08(4)(c)3.g. g. Hardwood swamp located south of highway 10.

NR 103.08(4)(c)3.h. h. Conifer swamp located south of highway 10.

NR 103.08(4)(c)3.i. i. Cedar swamp located north of highway 10.

NR 103.08(4)(d) (d) For cranberry operations, the department, utilizing the factors in sub. (3) (b) to (g), shall make a finding that the requirements of this chapter are satisfied if it determines that the project proponent has shown that the activity will not result in significant adverse impacts to wetland functional values, significant adverse impacts to water quality or other significant adverse environmental consequences. For the purposes of determining whether there is a practicable alternative to a proposed expansion of an existing cranberry operation, the analysis shall be limited to alternatives within the boundaries of the property where the existing cranberry operation is located and on property immediately adjacent to the existing cranberry operation. For new cranberry operations, a practicable alternatives analysis shall be conducted which includes off-site alternatives.

NR 103.08(4)(e) (e) Mitigation projects and the use of wetland mitigation banks shall be carried out in accordance with ch. NR 350 and any memorandum of agreement between the department and the United States army corps of engineers that establishes guidelines for mitigation projects and wetland mitigation banks.
