Dredging Projects

  • Sediment Testing for Dredging Projects

    Permits are required for dredging lake or river bottoms pursuant to Part 325, Great Lakes Submerged Lands or Part 301, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended. If the Water Resources Division (WRD) is able to permit your dredging project, dredge material characterization is required by the Department of Environmental Quality (DEQ). Sediment testing results need to be submitted with a permit application to be evaluated as part of the proposed project.
