ADDITIONAL COMMENTS:
No discharge was observed at the time of visit. The contractor is using temporary swales and a Baker tank to impound
onsite water and received a permit to discharge construction storm water to King County sanitary sewer. A water
sample was taken from the NE swale; the sample had a turbidity of 34 NTU. AESI reminded the contractor the cover
stockpiles prior to the oncoming rain this weekend. AESI will return next week.
