Indiana’s In-Lieu Fee Mitigation Approved by the Corps

The U.S. Army Corps of Engineers Louisville, Detroit and Chicago Districts approved the Indiana Department of Natural Resources (IDNR) In-Lieu Fee Program Instrument.

In-Lieu Fee (ILF) mitigation allows a permittee to purchase credits from an ILF Program instead of completing project-specific mitigation or purchasing credits from an approved mitigation bank. The IDNR ILF Program is authorized to provide mitigation associated with Department of Army (DA) Permits pursuant to Section 404 of the Clean Water Act and Section 10 of the River and Harbors Act of 1899 (33 U.S.C. 401), and Indiana Department of Environmental Management (IDEM) permits pursuant to Section 401 of the Clean Water Act and Indiana State Isolated Wetlands Law (IC 13-18-22), within the State of Indiana. The IDNR ILF Instrument is available on the Corps “Regulatory In-Lieu Fee and Bank Information Tracking System” (RIBITS) internet site.

Permittees wishing to purchase mitigation credits from the IDNR ILF Program, should contact IDNR by calling Carl J. Wodrich at (317) 232-1291, emailing at, or by writing to Wodrich at Indiana Department of Natural Resources, 402 W. Washington Street, W255A, Indianapolis, Indiana, 46204, to determine mitigation credit availability and credit fee structure. Please note that, in accordance with the Mitigation Rule, the cost per mitigation credit is set by the sponsor.
