On Monday April 6, 2009, AES, Southern Illinois Railcar, U.S. EPA and START participated in a kick-off meeting. The purpose of the meeting was to share the planned project activities and schedule. START and AES conducted a short site visit to evaluate conditions and observe water management at the site.
On Tuesday April 7, 2009 AES started to remove scrap metal left from the demolition of the South Warehouse. AES started to move the stone debris impacted with PCBs into piles to prepare the material for transport to the landfill disposal facility. AES performed air monitoring to evaluate air quality during removal activities.
On Wednesday April 8, 2009 AES started removal activities of the stone debris material from the former South Warehouse. A total of 32 truck loads transported 616 tons of stone debris from the site to the landfill disposal facility.

A total of 34 truck loads transported 645 tons of material from the site to the landfill disposal facility. AES completed the removal of scrap metal left from the demolition of the former South Warehouse. AES performed air monitoring to evaluate air quality during removal activities.
On Friday April 10, 2009 AES continued removal activities of the impacted stone debris from the former South Warehouse. A total of 36 truck loads transported 663 tons of stone debris from the site to the landfill disposal facility. AES also conducted water quality measurements from the Warrington Ditch at two locations at the site. AES collected readings downstream near the rail road spur and collected the following readings: pH 7.78, temperature 8.3 degrees Celsius, and ammonia at 0.0 ppm. Water quality readings were also collected upstream at Hook Waltz Road. The following measurements were recorded: pH 8.02, temperature 8.8 degrees Celsius, and ammonia at 0.0 ppm. AES performed air monitoring to evaluate air quality during removal activities.
The storm water management task will continue during removal activities.
To date, a total of 1,924 tons of impacted stone debris has been removed and disposed at County Environmental of Wyandot located in Carey, Ohio. Additionally, 2,521,824 gallons of ammonia water has been transported offsite to United Wastewater and 108,000 gallons has been transported to Lima Wastewater.
