Blue Earth County (County Road 156 bridge replacement) - 401 Water Quality Certification
We invite you to comment on the draft 401 Water Quality Certification for the County Road 156 / 597th Avenue Bridge #90555 replacement in Blue Earth County.
The Blue Earth County Public Works Department proposes to replace the bridge that conveys County Road 156 (also known as 597th Avenue) over County Ditch 96 (also known as Big Slough), located southeast of Mapleton. At the same time, the county will align County Ditch 96.
The bridge replacement will impact 0.18 acres of wetlands, which the county will mitigate at a 2:1 replacement ratio. The ditch alignment will impact 0.21 acres of wetlands, which the county is not required to mitigate. The project will either maintain or improve water quality after 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.
