Koppers Cleanup Update

For those following the cleanup at the old Koppers railroad tie manufacturing plant, even more important now because of the desire of Brightfields to install a solar array there for energy production, here is the most recent status report on the cleanup. Beezer is the company handling the actual cleanup:

On July 14, 2014, Beazer submitted to USEPA tables and a figure summarizing available soil sample
data for the railroad property and 35-foot Beazer-owned swath located south of the Site.

 On July 28, 2014, Beazer submitted to USEPA a Human Health Risk Assessment Work Plan.

 On July 29, 2014, USEPA responded to questions received from the Concerned Carbondale Citizens.

 On July 30, 2014, Beazer and Brightfields conducted a public information session for solar land use at
the Site.

 Beazer, USEPA and others participated in corrective action coordination conference calls on July 11
and 24, 2014.

 Beazer continued post-construction OMM activities (e.g., DNAPL thickness measurements/removal,
CAMU leachate monitoring/removal, Site inspections, etc.).

 Beazer collected approximately 70 gallons of DNAPL from the barrier trench and approximately 20
gallons of DNAPL from recovery well RW-23 during this reporting period. The approximate total
DNAPL volumes collected through July 2014 are 18,321 gallons from the barrier trench and 7,438
gallons from RW-23.
