Aquatic Noxious Weed Control NPDES General Permit
The general permit covers the indirect discharge of herbicides, adjuvants,
and marker dyes into estuaries, marine areas, wetlands, along lake shorelines,
rivers, streams, and other wet areas to manage Spartina and freshwater noxious
weeds in Washington. An indirect discharge occurs when there may be incidental
overspray or dripping of a chemical from the treated plants into waters of the
state.
