Maple Grove Township Leisure Lane Bridge Replacement – 401 Water Quality Certification

We invite you to comment on the draft 401 Water Quality Certification for the Maple Grove Township Leisure Lane Bridge Replacement project in Crow Wing County.

Maple Grove Township has applied for the permanent discharge of fill material into 280 linear feet of the Nokassippi River, 2,744 square feet (sq ft) of Upper South Long Lake, and 3,398 sq ft of adjacent wetlands to replace a deteriorated timber bridge (L5862) with a double-barreled box culvert and distribution slab. Road widening, placement of riprap for bank stabilization and erosion prevention, and 44 sq ft of temporary impacts to the Nokassippi River are proposed. Wetland mitigation credits will be purchased through the Board of Water and Soil Resources Local Government Road Wetland Replacement Program.

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.
