Koppers Report

Here's what Beazer, the company tasked with cleaning up the old Koppers site (where Brightfields hopes to locate its solar production array), has accomplished since the last report:

Items Performed/Completed Since Previous Report:
 On August 4, 2014, Beazer submitted a letter to USEPA addressing USEPA’s suggestion of
groundwater sampling for dioxins/furans as stated in the agency’s July 29, 2014 letter responding to
questions received from the Concerned Carbondale Citizens.

 On August 20, 2014, USEPA provided Beazer with preliminary comments on the July 28, 2014 Human Health Risk Assessment Work Plan.

 Beazer, USEPA and others participated in corrective action coordination conference calls on August 7 and 21, 2014.

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

 Beazer collected approximately 123 gallons of DNAPL from the barrier trench and approximately 38 gallons of DNAPL from recovery well RW-23 during this reporting period. The approximate total
DNAPL volumes collected through August 2014 are 18,444 gallons from the barrier trench and 7,476
gallons from RW-23.
