Ecology finds OutPak Corrugate Washout functionally equivalent to Best Management Practice C154 (Concrete Washout Area) for stormwater management.

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.
