Welcome to the U.S. Army Corps of Engineers, Louisville District, Regulatory Division Home Page.
The Regulatory Division of the U.S. Army Corps of Engineers Louisville District is responsible for administering the Regulatory Program in the majority of Indiana and Kentucky, the southeastern portion of Illinois, and the Ohio River to southwestern Ohio. The Regulatory Division evaluates permit applications for essentially all work that occurs in “waters of the United States (U.S.)” that are regulated by the Corps pursuant to Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. Some examples of areas that may be within the jurisdiction of the Corps include marshes, swamps, streams, creeks, rivers, ponds, lakes, seasonally saturated forested and non-forested wetlands.
All regulated activities occurring within jurisdictional areas require a permit from the Corps. Some example activities occurring within jurisdictional areas that require a permit include dredging of waterways, bank stabilization, recreational ponds and lakes, as well as the construction of piers, docks, marinas, fleeting areas, boat ramps, roads, residential and commercial developments, utility lines, and mining activities.
In order to determine whether your proposed activity requires a permit, or whether any “waters of the U.S.” are located on your property or within your project area, please explore our website or contact us for further guidance. Please note that the Louisville District Corps of Engineers will make the final determination of whether an area is a jurisdictional “water of the U.S.” and whether the activity requires a permit.
We are dedicated to providing strong protection of the Nation’s aquatic environment, including wetlands, to enhancing the efficiency of the Corps administration of its regulatory program, and to ensuring that the Corps provides the regulated public with fair and reasonable decisions.

10 June 2019 - The U.S. Army Corps of Engineers, as part of an interagency effort with the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture - Natural Resources Conservation Service, announces the draft biennial update to the National Wetland Plant List (NWPL) for 2018 in the Federal Register. The Corps encourages public input in the form of data, comments, literature references, or field experiences, to help clarify the status of the species reviewed for this update, as well as public input on the NWPL process. The public will have the opportunity to comment on the proposed update or addition of wetland indicator status ratings for 20 plant species in select Corps wetland regions. These 20 reviewed species and their draft 2018 wetland ratings by region, as well as the FR notice, can be viewed at the NWPL homepage, https://wetland-plants.usace.army.mil/ under “2018 NWPL Update Information.” A link to provide general or species-specific comments is also available at this location. Users are encouraged to submit literature citations, herbaria records, experiential references, monitoring data, and other relevant information. Specific knowledge of, or studies related to, individual species are particularly helpful. Commenters should use their regional botanical and ecological expertise, field observations, reviews of the most recent indicator status information, appropriate botanical literature, floras, herbarium specimens with notation of habitat and associated species, habit data, relevant studies, and historic list information. Guessing ratings is inappropriate. All submitted comments and information will be compiled and sent to the National Panel for their consideration.
The Corps is also seeking comments on the NWPL update process. Detailed information on the update process, protocol, and technical issues can be found in the following documents (available on the NWPL Publications web page referenced above):
