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. No water
sample was taken at the time of visit as the swale was recently pumped. AESI reminded the contractor to cover unused
stockpiles and exposed soils before the oncoming rain.
