For those following the Kopper's site cleanup, here is the latest update on how it is progressing:
Items Performed/Completed Since Previous Report:
On March 5, 2015, USEPA provided written comments on the Human Health Risk Assessment (HHRA)
that was submitted by Beazer on November 26, 2014.
On March 24, 2015, the Carbondale City Council approved a Special Use Permit for a commercial solar
energy facility at the Site.
Beazer, USEPA and others participated in corrective action coordination conference calls on March 12
and 26, 2015.
USEPA and ARCADIS participated on a conference call on March 19 to discuss USEPA comments
related to developing a revised groundwater monitoring program for the Site.
Beazer continued post-construction OMM activities (e.g., DNAPL thickness measurements/removal,
CAMU leachate monitoring/removal, Site inspections, etc.).
Beazer collected approximately 87 gallons of DNAPL from the barrier trench and approximately 46
gallons of DNAPL from recovery well RW-23 during this reporting period. The approximate total
DNAPL volumes collected through March 2015 are 19,190 gallons from the barrier trench and 7,673
gallons from RW-23.
Items Anticipated to be Performed/Completed over the Next One to Two Months:
Beazer, USEPA and others will work on action items from the February 18, 2015 meeting, as
documented in a February 23, 2015 letter from Beazer and as discussed during the March 12, 2015
conference call.
Beazer will submit a revised HHRA to USEPA.
USEPA will provide comments on the October 2008 Draft Groundwater Monitoring Plan.
Beazer and USEPA will participate in a conference call to discuss an ecological risk management
approach for the Site.
Beazer will propose a draft scope of a monitored natural recovery (MNR) program for residual impacted
sediment areas.
Beazer, USEPA and others will continue to participate in corrective action coordination conference calls.
Items Anticipated to be Performed/Completed over the Next Two to Six Months:
Beazer will continue to advance proposed future Site uses, including conservation land use and
commercial solar energy.
USEPA will conduct a public meeting in Carbondale.
Items that May Cause Delay in Implementing Future Activities and Efforts (if any) to Limit Such
Delays:
None.
