NR 350.005(2)
(2) The department will determine the amount of mitigation required on a case-by-case basis based on the quality and type of wetlands impacted, the duration of the impacts, the measure of lost wetland function, the temporal loss of wetland function, and the location of the proposed mitigation. The department shall ensure that the loss of wetland function due to adverse impacts associated with an individual permit or exemption is compensated for with an appropriate mitigation amount. The department shall evaluate the lost function of impacted wetlands using one of the following methods:
NR 350.005(2)(a)
(a) The department may use an appropriate wetland functional or condition assessment method such as the Wisconsin rapid assessment method, or another department approved method designed to measure impacts to wetland functions and values.
NR 350.005(2)(b)
(b) The department may use a crediting system based on wetland type, location, or function to measure wetland impacts and wetland mitigation potential. If mitigation is required for adverse impacts to wetlands and the department uses a crediting system to evaluate the impacts, all of the following apply:
NR 350.005(2)(b)1.
1. If the department requires the permittee or exempt project proponent to purchase mitigation bank credits from a wetland mitigation bank, the mitigation required for the wetland impacts shall be no less than 1.2 credits per one acre of direct impacts for mitigation bank credits purchased in the same service area and of the same wetland community type. The department may require a higher mitigation ratio for bank credits under the following circumstances:
NR 350.005(2)(b)1.a.
a. The ratio may be increased for the purchase of mitigation bank credits out-of-kind from the impacted wetland community type.

c. The ratio may be increased for the purchase of mitigation bank credits to offset temporal loss of wetland functional values associated with the mitigation credits.
NR 350.005(2)(b)1.d.
d. The ratio may increase to fully compensate for impacts to wetland function and acreage.
NR 350.005(2)(b)2.
2. If the department requires the permittee or exempt project proponent to purchase credits from an approved in-lieu fee program, the ratio for mitigation shall be no less than 1.45 credits per one acre of direct impacts to compensate for the adverse impacts to wetlands and to account for the temporal loss of wetland acres and function.
NR 350.005 Note
Note: The department makes decisions on the amount of mitigation required in consultation with the U.S. army corps of engineers and in accordance with federal wetland mitigation regulations and guidelines.
NR 350.005(2)(b)3.
3. If the department determines that the permittee or exempt project proponent shall complete a permittee-responsible mitigation project for direct wetland impacts, the starting mitigation ratio shall be no less than 1.2 credits per one acre of direct impacts. The required mitigation amount for a permittee-responsible mitigation project shall be determined on a case-by-case basis and may include ratio increases for impacts to rare wetland types, out-of-kind wetland mitigation, temporal wetland functional loss, or for mitigation in a different service area than where the discharge occurred.
NR 350.005(3)
(3) The department may determine that mitigation is required for secondary impacts to wetlands associated with wetland individual permits or exemptions.
NR 350.005 Note
Note: The department may require mitigation for secondary impacts to wetlands such as conversion of wetland type or hydrologic impacts.
NR 350.005(4)
(4) The department may determine that mitigation is required for temporary impacts to wetlands associated with wetland individual permits or exemptions.
NR 350.005 Note
Note: The department may require mitigation for temporary impacts to wetlands such as forested wetland clearing, or temporary impacts to any wetland plant community that is dominated by native plant species.

NR 350.006(9)
(9) The department may allow credit for wetland areas according to their mitigation activity type if a mitigation project proposes to include areas of shallow or deep marsh if all of the following are met:
NR 350.006(9)(a)
(a) The shallow or deep marsh areas on the site may receive credit if they provide increased wetland function, meet approved performance standards, and allow the other areas of the site to provide increased wetland function and meet performance standards.
NR 350.006(9)(b)
(b) The shallow or deep marsh areas of the site are ecologically suitable to the landscape as evidenced by historic and current site conditions and are proposed to be constructed according to the best available scientific understanding of natural, self-sustaining conditions.
NR 350.006(10)
(10) If engineered structures that require active management, such as berms, dikes, or water control structures, are proposed to be constructed on the site, all of the following apply:
NR 350.006(10)(a)
(a) The structures must only be necessary to restore the site to the extent practicable considering historic and current site conditions, historic and current watershed features, and will result in wetland communities that are appropriate for the hydrology on site and in the proximate watershed.
NR 350.006(10)(b)
(b) The mitigation sponsor shall provide maintenance and monitoring plans, identify the person or entity responsible for long-term maintenance, and identify financing mechanisms to ensure continued operation of those structures and these shall be reviewed by the department as part of a compensation site plan under s.
NR 350.007 (4).
NR 350.006(11)
(11) The department may require a buffer zone on the mitigation site boundary to protect the site from potential adverse impacts from neighboring land uses or conditions. The department may award less credit for restoration, enhancement, or creation activities in a buffer zone than for similar restoration, enhancement, or creation activities not occurring in the buffer zone.
NR 350.006(12)
(12) If a mitigation project includes areas of vegetation establishment on uplands, the department will allow credit at no higher than one credit for every four acres established and the total upland buffer credits on a project shall not exceed 25 percent of the total mitigation project credits. Any credits produced from upland restoration activities will be released as wetland credit based on the proportion of the total acreage projected for each proposed wetland type.
NR 350.006(13)
(13) The department will not award mitigation credit for projects used primarily as stormwater or wastewater treatment facilities or similar projects under s.
