Aquatic Invasive Species Management General Permit

The Aquatic Invasive Species Management General Permit (permit) is a combined National Pollutant Discharge Elimination System (NPDES) and State Waste Discharge General Permit. It covers the in-water treatment of aquatic invasive species animals and nonnative invasive marine algae. This permit will allow for the treatment of early infestations and for small localized projects that may lead to the eradication of the invasive species from each site, or for the containment of the invasive species to one area or site. The permit allows the discharge of a specific list of chemicals and control products into the fresh and marine waters of Washington.
