OSC Kelly conducted a windshield assessment at the Site on May 2, 2011, and determined that a sampling assessment should be conducted at the Site.  During the sampling assessment that was conducted on June 28-29, 2011, a total of five surface water samples, five sediment samples, and 15 surface soil samples were collected from the Site.  All of the samples collected were analyzed for TAL metals, mercury, and PCBs.   Lead was detected at concentrations up to 2.6 ug/L in the surface water samples, up to 68.8 mg/kg in the sediment samples, and up to 116,000 mg/kg in the surface soil samples.

On November 28, 2011, ERRS and OSC Francisco Cruz mobilized to the Site.  START mobilized to the Site on November 29, 2011.  During the week of November 28, 2011, ERRS scraped and excavated 6” of lead contaminated soil from the level area behind the building.  After the excavation, START created a grid and screened the surface soil using the XRF to determine if elevated concentrations of lead remained in the soil.  All surface soils contained lead concentrations below 400 ppm and no further excavation was necessary.  Excavated soil was put into roll-off dumpsters or end dump trailers for T&D as hazardous soils.

ERRS then scraped and excavated 6” of lead contaminated soil from the slope leading to the Bluestone River.  After the excavation, START created a grid and screened the surface soil using the XRF to determine if elevated concentrations of lead remained in the soil.  A portion of the slope contained high concentrations of lead and an additional 6” excavation was performed at the area of concern.  A second XRF screening indicated all lead concentrations below 400 ppm and no further excavation was necessary.  Excavated soil was put into roll-off dumpsters or end dump trailers for T&D as non-hazardous soils.  START performed air monitoring during all excavation activities.  ERRS deconed all equipment after excavation was complete and backfilled all areas behind the building with clean soil.

ERRS performed HAZCAT chemical identification and START performed XRF screening on an unknown drum material discovered inside the building.  The material consisted of mostly iron and calcium and was deemed safe to mix with the excavated soil for T&D as hazardous waste.  Other miscellaneous chemicals discovered inside the building were placed into drum overpacks for T&D pickup on December 8^th.

During the week of December 5, 2011, ERRS graded the soils behind the building.  ERRS also repaired the Site access roads that were damage from machinery.  ERRS received shipments of stone and finalized access road cover and stability after all equipment had been relocated.  ERRS cleaned and positioned the excavator for transportation off-Site. START performed photographic and written documentation of all Site activities.  The embankments adjacent to the Bluestone River and access roads, as well as the flat area behind the building were hydroseeded on December 9^th.

T&D operations of the "hazardous" soils and debris continued until December 9, 2011.  Through December 9, 2011, a total of 73.23 tons of "hazardous" debris (5 trucks of battery casings and bagged lead-contaminated debris from the building) were transported to EQ Detroit in Detroit, Michigan for disposal.  Additionally, 200.23 tons of "hazardous" soils (12 trucks of lead-contaminated soils from the exterior of the building) were transported to EQ Detroit in Detroit, Michigan for disposal.
