The department proposes to issue a Section 401 Water Quality Certification to Andrew Weltman, subject to general or special conditions. The department invites the public to review and offer written comments on the proposed certification conditions until June 12, 2026. The public can review the proposed certification conditions below. Other relevant information is available for review and copying upon request. Written comments may be submitted by mail to Missouri Department of Natural Resources, Water Quality Certification, PO Box 176, Jefferson City, MO 65102-0176 or by email to wpsc401cert@dnr.mo.gov.

Andrew Weltman requested Section 401 Water Quality Certification to accompany the U.S. Army Corps of Engineers' (USACE) Permit for Nationwide Permit (NWP) MVS-2026-160 for the Chateau Lane Culvert Maintenance project. The proposed project does not comply with the state of Missouri’s 2026 programmatic general WQC condition 11; therefore, an individual WQC is required. General condition 11 states that Programmatic WQC is denied for any NWP issued on a water that is listed in the Section 305(b) Integrated Water Quality Report that has been most recently approved by the EPA for: organic sediment, inorganic sediment, sedimentation/ siltation, suspended solids, lead, cadmium, zinc, metals, aquatic macroinvertebrate bioassessments, fishes bioassessments, habitat assessment-streams, habitat loss, physical substrate habitat alterations, or unknown impairments [10 CSR 20-7.031(4-5)]. The Section 305(b) Integrated Water Quality Report includes both the 303(d) impaired waters list and approved Total Maximum Daily Loads. Fox Creek is designated on the 2022 Missouri 303(d) List as impaired for Aquatic Macroinvertebrate Bioassessments from unknown sources in the most current Missouri Water Quality Report (Section 305(b) Report).
This certification is being issued under Section 401 of Public Law 95-217, the CWA of 1977 and subsequent revisions. Pursuant to Section 121.7(d), this office certifies the proposed project will comply with Missouri water quality requirements.
