Great Lakes Dredging Team 2018 Fall Webinar: December 12, 2018


Meeting Summary


Ohio 2018 Dredged Material Summit: October 15, 2018

Summit Agenda


Discussion Topics Include:

  • Ohio’s Dredge Strategy
  • Sediment Profiling
  • Ohio Beneficial Use Rules Updates

Breakout Sessions On:

  • Dredge to Habitat – discussing benefits of dredge material to improve fish and wildlife habitat, enhance recreation and improve water quality
  • Dredge to Marketable Soil – discussing how dredge can be essentially converted into a marketable product
  • Dredge to Farmland – discussing dredge repurposes to enhance near-lake farmland

Great Lakes Dredging Team Annual Meeting: May 2018 – Toledo, OH


Webinar – Beneficial Use of Dredged Material: Can Soil Sales Save Peoria Lake?: March 19, 2018

Manufacturing custom soil blends from dredged sand in private-public partnerships has been demonstrated in St. Paul Minnesota where the MN Department of Transportation requires specified drainage and growth characteristics for roadside topsoil. The technology is transferable to other regions if the feedstock materials, manufacturers, and customers can be identified and matched in a local market. Successful soil markets can extend the life of Corps CDFs, create economic opportunity, and improve watershed hydrology and water quality with improved stormwater management. New projects are being explored in Ottawa, IL, Pekin, IL, and Wabasha, MN. Municipal port authorities may be an important agent coordinating private and public partners.

Speaker: Chuck Theiling, U.S. Army Corps of Engineers, Engineer Research and Development Center

Great Lakes Dredging Team Fall Webinar: December 7, 2017


Sediment Choreography Webinar: October 24, 2017

This informational webinar will explore new approaches to upstream management practices using a river’s natural energy to reduce sediment load – and thus the amount of downstream dredging required – in Great Lakes commercial ports and recreational harbors. Using the Port of Cleveland’s experience, and other case studies, the discussion will also include strategies to recognize and maximize the value of collected bedload sediment as a commodity, rather than having to manage it as a solid waste.

Using dredged material for aquatic habitat restoration, leading to AOC delisting: A multi-win approach in Duluth-Superior Harbor: May 1, 2017

This informational webinar hosted by the Great Lakes Dredging Team detailed an innovative project underway in the Duluth-Superior harbor. Using cleaner sediment dredged from the harbor’s navigation channels, a section of the harbor bed polluted by a legacy of industrial activity is being restored as viable aquatic habitat, and hopefully delisted as an EPA-designated Area of Concern. The presentation includes perspectives from the Duluth Seaway Port Authority, the Minnesota Pollution Control Agency, and the U.S. Army Corps of Engineers.

Transportation of Dredged Material Webinar: April 22, 2016

The practicality of using clean dredged material beneficially in the Great Lakes, instead of disposing or impounding it, often turns on the critical factor of how the material is, or could be, moved. Current federal policy for dredged material management mandates the “least cost alternative,” which typically involves placement closest to dredging operations in the open waters of the lakes, in confined disposal facilities or in nearshore areas for beach nourishment and similar uses. Only a minuscule amount of Great Lakes dredged material – about 4% between 1998 and 2014 by volume – was placed in upland sites, where most opportunities for beneficial use are located. As ports increase efforts to identify new strategies to use clean dredged material beneficially, the added costs, infrastructure, modal availability, environmental regulations and other challenges involved with transporting the material loom as major challenges.

This one-hour webinar will discuss the transportation component of existing and potential dredged material beneficial use projects in the Great Lakes, covering such issue areas as which transportation modes – barge, truck, rail, hydraulic pipelines – are best suited for specific beneficial use scenarios; how added transportation costs can be integrated into a dredged material management plan; what environmental considerations need to be addressed; what infrastructural needs are involved; and whether social acceptance issues are involved.

Great Lakes Dredging Team Annual Meeting: June 2015, The District Event Center, Green Bay, WI


Cat Island Restoration Project Webinar: May 15, 2015

The Cat Island Restoration project involves reconstruction of the Cat Islands protecting and restoring approximately 1,225 acres of shallow water and wetland habitat with construction of a 2.5-mile long wave barrier along the remnant Cat Island shoals.  The wave barrier will protect and restore shallow water and wetland habitat and provides the base for constructing three islands which will be built from beneficially reused dredged material from the outer navigation channel.  The project is a partnership between the Port of Green Bay, Brown County, US Army Corps of Engineers, US Environmental Protection Agency, US Fish & Wildlife Service, Wisconsin Departments of Transportation and Natural Resources, Lower Fox River/Green Bay Natural Resources Trustee Council, UW Sea-Grant, UW-Green Bay and 14 port terminal operators.

Topics Included:

  • History of the Project
  • Dredge Material Management Plan
  • Cooperative Agreement
  • Design
  • Construction and Post-Construction
  • Lessons learned in implementation to date
