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:
