Stauber Announces $4.5 Million EPA Funding

Stauber Announces $4.5 Million EPA Funding

Sediment cleanup in the St. Louis River Area

HERMANTOWN, MINNESOTA ~ April 1, 2020  (LSN)  Congressman Pete Stauber (MN-08) announced that the U.S. Environmental Protection Agency (EPA) has signed a $4.5 million agreement to remediate contaminated sediment in the St. Louis River Area of Concern (AOC) on Lake Superior.

Of this announcement, Congressman Stauber stated, “I am incredibly happy to announce this funding agreement today because in addition to serving as a special place for many Minnesotans, Lake Superior is also a vital component of our tourism and shipping industries. By investing in the health and vitality of the St. Louis River, which flows into the Port of Duluth and ultimately Lake Superior, we are preserving this national treasure for future generations to enjoy, supporting the Port of Duluth, and guaranteeing continued economic prosperity by extension.”

The U.S. Environmental Protection Agency (EPA) has signed a $4.5 million agreement to remediate contaminated sediment in the St. Louis River Area of Concern (AOC) on Lake Superior. The St. Louis River AOC is one of 43 toxic hotspots identified by the United States and Canada in the Great Lakes basin, and is the second largest AOC in the United States. EPA and the Minnesota Pollution Control Agency (MPCA) will fund the work through a Great Lakes Legacy Act cost-sharing partnership.

“EPA’s partnership with Minnesota continues to produce results in the St. Louis River AOC,” said EPA Great Lakes National Program Manager and Regional Administrator Kurt Thiede. “This sediment cleanup will address a century’s worth of contamination, protecting public health and aquatic life while improving access to a port that is critical to the region’s economy.”

The project will remediate approximately 55,000 cubic yards of contaminated sediment in the Azcon/Duluth Seaway Port Authority slip, an active 6.5-acre shipping slip located in the Duluth-Superior Harbor. The sediment is primarily contaminated with polycyclic aromatic hydrocarbons, or PAHs. Approximately 600 cubic yards of the most contaminated sediment in the Slip will be removed and properly disposed of. The remainder will be capped in place with clean sediment to prevent exposure to aquatic organisms. The cap will be armored with stone to protect against damage from vessel traffic.

The MPCA has agreed to contribute up to $1,575,000 to the total project cost of $4.5 million.

“Signing this project agreement and receiving $2,925,000 in federal funding opens the door to completing this project, the fourth of ten remedial projects, in 2020,” said LaRae Lehto, sediment coordinator for the MPCA.

The cleanup will reduce toxins in the benthic (i.e., bottom dwelling) community, macroinvertebrates which live in the sediment and provide an important food source for fish. As a result, toxins will be reduced in fish, making them safer to eat. The cleanup will contribute to the removal of three of the St. Louis River AOC’s seven remaining "Beneficial Use Impairments," or BUIs:

  • Restrictions on Dredging
  • Degradation of Benthos
  • Fish Consumption Advisories

The projects is slated to begin this summer with the help of the U.S. Army Corps of Engineers.

This project is part of the larger effort to restore and protect the Great Lakes through the Great Lakes Restoration Initiative (GLRI). In October 2019, EPA Administrator Andrew Wheeler announced the GLRI Action Plan III, an aggressive plan that will guide Great Lakes restoration and protection activities by EPA and its many partners over the next 5 years.
