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.
