Restriction on Dredging
IJC Criteria: An impairment will be listed when contaminants in sediments exceed standards, criteria, or guidelines such that there are restrictions on dredging or disposal activities.
SLR RAP Rational for Listing: Restrictions on dredging is a use that can be clearly identified as impaired in the St. Louis River AOC. Sediments in many parts of the AOC exceed guidelines developed by regulatory agencies to characterize in-place sediments and contain a variety of toxic, bio-accumulative contaminants that have been shown to cause adverse effects to aquatic and terrestrial organisms. Serious economic and social consequences are also imposed upon some resource users through special dredging requirements and obligations for long-term sediment containment.
