St. Louis County (Maple Grove Road reconstruction and culvert replacement) - 401 Water Quality Certification
We invite you to comment on the draft 401 Water Quality Certification for the Maple Grove Road/County State Aid Highway 6 reconstruction and culvert replacement in St. Louis County.
The St. Louis County Public Works Department proposes to resurface 3.55 miles of Maple Grove Road in Solway Township. The project includes replacing a culvert where Maple Grove Road crosses an unnamed tributary to the Pine River. The project will impact 79 square feet of the unnamed tributary, install 213.6 square feet of riprap below the tributary’s ordinary high-water level, and permanently impact 1,304 square feet of wetland. The county will mitigate the wetland impacts using local road bank credits at a 1:1 replacement ratio within the same bank service area as project. The water quality will be maintained or improved after project completion.
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.
