Analysis by the Legislative Reference Bureau
This bill makes changes to requirements for wetland mitigation banks.
Under current law, the Department of Natural Resources must issue wetland
general permits for discharges of dredged or fill material into certain wetlands and
may require a person to apply for and obtain a wetland individual permit if DNR
determines that conditions specific to the site require additional restrictions on the
discharge in order to provide reasonable assurance that no significant adverse
impacts to wetland functional values will occur. Under current law, before DNR may
issue a wetland individual permit, it must require the restoration, enhancement,

creation, or preservation of other wetlands to compensate for adverse impacts to a
wetland resulting from the discharge, also known as mitigation.
Under current law, there are three methods by which wetland mitigation may
be accomplished: 1) purchasing credits from a mitigation bank located in this state;
2) participating in the in lieu fee subprogram; or 3) completing mitigation within the
same watershed or within one-half mile of the site of the discharge. A mitigation
bank is a system of accounting for wetland loss and compensation in which sites
where wetlands are restored, enhanced, created, or preserved generate credits that
may be applied or purchased in order to compensate for adverse impacts to other
wetlands. Under current law, DNR must approve the establishment of a mitigation
bank.
This bill changes the first method of wetland mitigation by limiting credit
purchases to only a mitigation bank located in the same hydrologic unit code (HUC)
8 as the wetland impacted by the discharge, if available. Under the bill, an HUC 8
is a watershed delineated by the U.S. Geological Survey using a nationwide system
based on surface hydrologic features at the 8-digit subbasin scale. If no available
mitigation bank is located in the same HUC 8 as the wetland impacted by the
discharge, the bill allows credit purchases to be made from a mitigation bank located
within the same bank service area as the wetland impacted by the discharge. Under
the bill, a bank service area is the geographic area corresponding to the HUC 6 within
which impacts to a wetland from a discharge can be mitigated at a specific mitigation
bank as determined in an agreement between DNR and the U.S. Army Corps of
Engineers and referenced in a mitigation banking instrument. Under the bill, an
HUC 6 is a watershed delineated by the U.S. Geological Survey using a nationwide
system based on surface hydrologic features at the 6-digit basin scale. If no available
mitigation bank is located in the same bank service area as the impacted wetland,
the bill allows credit purchases to be made from a mitigation bank in the same basin
as the wetland impacted by the discharge, meaning the Lake Michigan, Lake
Superior, or Mississippi River basin that corresponds to the HUC 2. Under the bill,
an HUC 2 is a watershed delineated by the U.S. Geological Survey using a
nationwide system based on surface hydrologic features at the 2-digit region scale.
However, despite these limitations on the location of a mitigation bank, the bill
allows DNR, in consultation with the U.S. Army Corps of Engineers, to allow credits
to be purchased from a different mitigation bank than the one prescribed or allow
mitigation to be done through the in lieu fee subprogram rather than by purchasing
credits from a mitigation bank if DNR determines it would better serve natural
resource goals, such as retaining flood water, improving or restoring wildlife habitat,
or more closely matching the impacted wetland type.
This bill requires DNR to establish by rule financial assurance requirements
for the construction of mitigation projects by mitigation banks. The bill also
establishes the means by which a mitigation bank that has not yet completed
construction of a mitigation project and has not been approved by DNR (developing
mitigation bank) may sell the credits that the mitigation bank estimates it will have
once the mitigation project is complete. Under the bill, a developing mitigation bank
may sell these credits if it is in compliance with DNR's financial assurance

requirements and if it follows a specific schedule for release of the credits that is
established in the bill. The bill allows DNR to authorize a developing mitigation
bank to sell its estimated credits at a faster rate than the schedule allows if the bank
provides an additional level of financial assurance or if the mitigation is of a type that
is less prone to failure, such as wetland preservation or enhancement.
