Spill site with 40,000 gallon UST diesel tank (access ports seen on asphalt on left side) and three AST day tanks. Note planter to left of tanks behind ladder. Storm drain #18 is to right outside photo. Three 250 gal diesel day tanks for generator. Left tank overflowed. Diesel came out through (visible) holes in front and down opening in concrete to left of tank leading to soil/pea gravel underneath. Day tank overflowed through pressure relief valves. Overflow alarms and shut-off valves failed. Rain release openings allowed diesel to spill onto asphalt, eating holes into parking lot to storm drain. Openings in containment area (incomplete construction) leading to gravel substrate (250 gal AST is on the right). The planter area to left of AST saturated with diesel. Removing soil in planter area. Planter area with most of soil removed. Opening shown from which diesel entered into the planter area. Removing contaminated soil underneath platform holding ASTs. Storm drain # 18 into which diesel poured. North Creek Parkway facing south under which storm drain flows. Vacuuming product in storm drain along North Creek Parkway. Wetland pond into which storm drain flow. No sheen seen on pond. Taking readings for volatile organic compounds as indicator of presence of diesel. Taking head space reading of sorbent boom or sweeps removed from storm drain. Presence of volatitle organic compounds above a certain action level indicates presence of diesel. Taking head space reading of boom or sweep in plastic bags. Geoprobing inside the generator building Diesel that entered into planter garden migrated along various undeground utility conduits, of which one lead to south side of generator building and continued along water main. Fuel was helped along by mulch-like material surrounding water main. Note: the storm drain is visible and watermain is parallel and to the right of storm drain. Parking lot with asphalt removed. Removing contaminated soil. Opening cut in slab floor of generator building in order to apply biosolution.
