  • General Information

    • Recycling Dredged Material in the Great Lakes
      Using dredged material can offset the need to mine or import sand or soil from other areas. This web site provides portals for obtaining information about sources of dredged material near you that can be used beneficially.

    • Decision Making Process for Dredged Material Management (pdf)
      This document has been developed by the Great Lakes Dredging Team in order to describe the decision making process used by the U.S. Army Corps of Engineers to determine the appropriate method(s) for management of dredged material from federal navigation projects, to describe the key environmental laws and regulations involved in this process, and to describe the responsibilities of other federal and state resource agencies and local proponents in this decision making process. A flow chart (page 22) provides a visual overview of the decisionmaking process for dredged material management, including the agencies and legislative authorities involved
      .

    • Great Lakes Dredged Material Testing & Evaluation Manual
      Developed by the Environmental Protection Agency and the Army Corps of Engineers in order to forecast potential impacts of contaminants from dredged material proposed for discharge to the Great Lakes,connecting channels and tributaries. This manual is intended to be used as a decision making tool for dredge and fill permits issued by the Army Corps of Engineers, or States or Tribes where delegated, under Section 404 of the Clean Water Act.

  • Environmental Windows
  • Environmental windows are time constraints place on dredging or dredged material operations to protect biological resources or their habitats from detrimental effects. Such windows can include, among other reasons, effects on resuspended sediments on fish and shellfish resources, sedimentation effects on sensitive resources and habitat, entrainment of aquatic organisms by hydraulic dredges and disruption during bird nesting times. The technical issues underlying requests for and compliance with windows are complex, as are the implications of windows for conduct of dredging in a cost effective manner. Windows complicate dredging contracts in many ways that can increase costs on a per cubic yard basis. Achieving a balance between adequate resource protection and cost effective dredging operations has been a continuous, challenge.
