Ecology Issues the New Aquatic Noxious Weed Management General Permit

The Washington state department of ecology (ecology) issued the aquatic noxious weed management general permit (permit) January 18, 2012.

Purpose of the Permit: The permit regulates the use of pesticides and other products applied to manage Washington state-listed noxious weeds and Washington state quarantine-listed weeds where pesticides or other products may indirectly enter the state's surface waters. An indirect application occurs when there may be inadvertent and incidental overspray or dripping of a chemical from the treated plants into waters of the state.

The permit covers all marine and freshwater activities that result in a discharge of herbicides, adjuvants, and marker dyes indirectly into streams, rivers, estuaries, marine areas, wetlands, along lake shorelines, and other wet areas. The permit also covers the treatment of noxious and quarantine-listed vegetation for roadside/ditch bank management activities where chemicals may indirectly enter the water. This permit does not apply to the in-water application of chemicals directly into lakes, ponds, streams, or rivers to manage freshwater noxious and quarantine-listed weeds. The aquatic plant and algae management general permit is the appropriate permit for any in-water projects.
