Carlton County (unnamed creek culvert replacement) - 401 Water Quality Certification
We invite you to comment on the draft 401 Water Quality Certification for the County Road 103 Clear Creek culvert replacement in Carlton County.
The Carlton County Transportation Department proposes to replace the culvert that conveys an unnamed tributary to the Nemadji River under County Road 103.
The existing culvert is failing, causing the road shoulder to slough. The county proposes to replace the existing 6-foot-by-4-foot culvert with a new 96-inch diameter culvert with a slightly skewed alignment to better match the natural stream alignment.
The project is expected to impact 210 linear feet of stream; no mitigation is 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.
