Wetlands are regulated at the local, state, and federal level. These regulations generally require approvals for activities that would impact a wetland. Impacts consist of filling, draining, or excavating within a wetland. Impacting a wetland without appropriate approvals may result in enforcement procedures.
If you have project that might impact wetlands, contact your Local Government Unit (LGU) to identify any required approvals.
If you want general wetland information access the BWSR website.
Applicants proposing impacts to aquatic resources (wetlands, lakes, stream, etc.) should submit the joint application form found on the BWSR website.

In Minnesota, the MPCA administers Section 401 of the Clean Water Act. Section 401 water quality certification ensures that projects comply with state water quality standards. MPCA has pre-certified many of the general Section 404 permits that are issued by the Corps, including certain general permits for projects that affect wetlands. Project of a large scope or direct impact, however, may require project specific 401 certification through the MPCA.
Among other things, MPCA also manages state water quality, including wetlands, the National Pollutant Discharge Elimination System (NPDES)/State Disposal System (SDS) program. NPDES/ SDS Permits are required from the MPCA for construction activities, including common plans of development, that disturb one acre or more of soil, disturb less than one acre of soil but the activity poses a risk to water resources.
