We invite you to comment on the draft 401 Water Quality Certification for UMD Neutrino Research Project in Lake County.

The University of Minnesota – Duluth, in partnership with other research laboratories across the country, proposes to install five frames on the bed of Lake Superior offshore from Two Harbors to look for neutrinos, a subatomic particle. The frames will be connected to shore by five underwater cables that will be brought through an unused pipe at the Two Harbors water intake plant.

This project is expected to last approximately one year, and 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.
