Water Quality Permits

For dredging projects

  • Portland Sediment Evaluation Team Memorandum
    Any project that involves dredging, dam removal, or any other kind of discharge of sediment will require coordination with the PSET team. DEQ will require a copy of the PSET memorandum prior to issuance. Protocols for sediment characterization and chemical analysis have been developed by a multi-agency workgroup led by the USACE; DEQ is a member of this group.
