We invite you to comment on the draft 401 Water Quality Certification for Keene Creek Re-alignment in St Louis County.

South St Louis SWCD proposes to re-align approximately 500 linear feet of Keene Creek and add a 21 inch by 15-inch concrete arch floodplain culvert alongside an existing culvert carrying Okerstrom Rd that will not be replaced. Mitigation is not required.

A 401 Water Quality Certification is required when an individual, business, or property owner proposes construction-related activities near a navigable lake, river, stream, or adjacent wetland. The MPCA reviews projects to ensure they will not violate Minnesota's more protective water quality standards. The 401 certification becomes an enforceable component of the associated federal license or permits issued under the Clean Water Act.
