Notice of Water Quality Certification

The Kansas Department of Health and Environment (KDHE) has drafted a water quality certification per Section 401 of the Clean Water Act (CWA) requested by Ireyimika Faith Alabi for the Kansas Department of Transportation (KDOT). The United State Army Corps of Engineers (USACE) CWA Section 404 Public Notice No. NWK-2024-00663 can be found at https://rrs.usace.army.mil/rrs/public-notices. The purpose of this project is to construct the north project portion of the South Lawrence Trafficway Project (KDOT Project No. 10-23 KA-3634-02). The scope of the project is to add two lanes to the existing two-lane roadway and will involve reconstruction of the existing interchange at I-70 and includes work on bridges and drainage structures which would result in the discharge of fill into a tributary of Baldwin Creek. The proposed structures will improve drainage and stabilize the existing roadway. Total impacts to aquatic resources would be approximately 800 linear feet, or 0.27 acres, of stream channel. A stream channel located on the east side of K-10 will also be affected by the project; however, this stream is not jurisdictional under the Clean Water Act. This project is programmed for a September 2026 letting.

The draft certification and additional information containing the link to the USACE Public Notice will be posted on the KDHE website at https://www.kdhe.ks.gov/1095/Section-401-Water-Quality-Certification. Persons wishing to comment on the referenced draft document must submit their comments in writing by email to the Kansas Department of Health and Environment at KDHE.NPS@ks.gov by May 16, 2026, if they wish to have their comments considered in the formulation of final determinations for 401 regarding this public notice.
