MPCA comment period opens on Kraemer dredge permit

The Minnesota Pollution Control Agency opened a 30-day public comment period Monday on a dredging permit sought by the St. Croix River Crossing project’s pier foundation contractor.

The MPCA is accepting written comments until Aug. 21 on the preliminary determination by the agency’s commissioner to issue a five-year permit to Edward Kraemer & Sons, Inc., of Burnsville to dredge material for construction of five bridge pier locations.

Kraemer plans to mechanically dredge approximately 25,000 cubic yards of silt and sand from pier locations in the St. Croix River and transport the material to shore on barges. Solids on the barges would be unloaded with a crane or excavator to transport trucks with sealed lift gates and hauled to designated reuse sites.

The MPCA said Kraemer would capture and dispose treatment solids along with dredge materials. If the water is drill slurry material that is no longer effective, the process will remain the same but the slurry would be treated in a different manner to capture solids from the free water, an agency statement said.

A draft permit can be reviewed at the MPCA’s St. Paul office or online at .

Written comments that include a statement of a person’s interest in the permit application or draft permit; statement of the action the writer wishes the MPCA take, including specific references to sections of the draft permit the writer believes should be changed, and reasons for the writer’s position with sufficient specificity to allow the MPCA to investigate the merits of the writer’s position should be sent to Emiliy Schnick, 5th Floor, Minnesota Pollution Control Agency, 520 Lafayette Road, St. Paul, MN, 55155-4194.

Interested parties can also petition the MPCA for an informational public meeting to offer comments and statements on the permit to help clarify and resolve issues.

Parties can petition for a contested hearing before an administrative law judge. The MPCA would grant a contested hearing petition if there is a material fact in dispute concerning the permit application; the agency has jurisdiction to make a determination, and there is a reasonable basis to allow introduction of information to aid the agency in resolving disputed facts in making a final decision on the draft permit.

Any written comments or petitions for either an informational public meeting or contested hearing must be submitted by 4:30 p.m. Aug. 21. If the agency receives no comments, requests or petitions during the public comment period, agency staff will make the final decision on the draft permit.
