Industrial Stormwater General Permit
"Ecology will apply a mixing zone where one is authorized
and consistent with Special Condition S3.E."
Ecology announced issuing the permit in the State
Register, WSR 02-16-094. Most industrial facilities that
discharge stormwater to a surface waterbody are included for
coverage under the industrial stormwater general permit. The
purpose of the permit is to protect waters of the state
through the regulation of industrial stormwater discharges.
The permit became effective September 20, 2002.
