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 animal species 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 or containment of invasive species.

Public Workshop and Hearing

The workshop and hearing will be an event at which you may learn about and provide formal comments on the draft permit.

The purpose of the workshop is to explain the general permit and to answer questions prior to the formal public hearing. The purpose of the hearing is to provide an opportunity for people to give formal oral testimony and comments on the proposed draft permit. Written comments will receive the same consideration as oral testimony. The public workshop will begin at 1:00 p.m. on June 21, 2016. The public hearing will begin immediately following the public workshop and will conclude when public testimony is complete. The workshop and hearing may also be attended as a webinar where individuals may view the presentation and provide testimony via computer.
