St. Louis River Area of Concern Updates: Scanlon Reservoir Sediment Remediation
Scanlon Reservoir Sediment Remediation
The Minnesota Pollution Control Agency (MPCA) is distributing this Environmental Assessment Worksheet (EAW) for a 30-day review and comment period pursuant to the Environmental Quality Board (EQB) rules. The MPCA uses the EAW and any comments received to evaluate the potential for significant environmental effects from the project and decide on the need for an Environmental Impact Statement (EIS).
An electronic version of the EAW is available on the MPCA Environmental Review webpage at https://www.pca.state.mn.us/regulations/projects-under-mpca-review. If you would like a copy of the EAW or NPDES permit, have any questions on the EAW or NPDES permit, contact the appropriate person(s)
Description of proposed project
The Minnesota Pollution Control Agency, in partnership with the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers, will conduct environmental cleanup in the Scanlon Reservoir in the St. Louis River Area of Concern. The objectives are to prevent contaminated sediment exposure to benthic organisms and other aquatic life, to prevent migration of contaminated sediments, and to improve aquatic habitat where feasible. The project consists of applying a 4-inch layer of sand amended with granular activated carbon over sediments in open-water areas, and broadcasting pelletized activated carbon in shallow wetlands areas of the reservoir where sediment contaminants exceed the cleanup criteria.
To submit written comments on the EAW
Written comments on the EAW must be received by the MPCA EAW contact person within the comment period listed above.
NOTE: All comment letters are public documents and will be part of the official public record for this project.
Need for an EIS
The MPCA Commissioner will make a final decision on the need for an EIS after the end of the comment period.
