The following construction activities require coverage under the Construction Stormwater

acres and discharges stormwater to surface waters of the State; and
2. Clearing, grading and/or excavation on sites smaller than one acre that are part of a

a) This includes forest practices(including, but not limited to, class IV conversions)
that are part of a construction activity that will result in the disturbance of one or
more acres, and discharge to surface waters of the State; and
3. Any size construction activity discharging stormwater to waters of the State that
Ecology:
a) Determines to be a significant contributor of pollutants to waters of the State of
Washington.
b) Reasonably expects to cause a violation of any water quality standard.
If there are known soil/ground water contaminants present on-site, additional information
(including, but not limited to: temporary erosion and sediment control plans; stormwater
pollution prevention plan; list of known contaminants with concentrations and depths found;
a site map depicting the sample location(s); and additional studies/reports regarding
contaminant(s))will be required to be submitted.
You may apply online or obtain an application from Ecology's website at:
http://www.ecy.wa.aov/programs/wq/stormwater/construction/ Application. Construction
site operators must apply for a permit at least 60 days prior to discharging stormwater from
construction activities and must submit it on or before the date of the first public notice.
Ecology's comments are based upon information provided by the lead agency. As such, they
may not constitute an exhaustive list of the various authorizations that must be obtained or legal
