2.1.1 Narrative
On September 3, 2013, crews loaded 13 trucks with treated soil from Pile E for off site disposal. Crews also began treating and excavating soil in area immediately east of excavation pit down to basement slab of original building. Crews are staging excavated soil into Pile G.
On September 4, 2013, crews loaded 13 trucks with treated soil from Pile E for off site disposal, which finished the disposal for Pile E. Crews resumed treating and excavating soil immediately east of excavation pit, along northern sidewalk border, down to basement slab of original building.
On September 5, 2013, crews loaded 9 trucks with treated soil from Pile F for off site disposal. Crews resumed treating and excavating soil along eastern edge of excavation pit down to basement slab of original building. Crews also treated and excavated Grid 8 to 2 feet bgs. START conducted XRF screening of Grid 8 and found lead levels >500ppm, so crews began excavating an additional 2 feet from Grid 8 and staging the treated soil in Pile G.
On September 6, 2013, START collected a waste disposal sample from Pile G. Crews resumed treating and excavating soil from Grid 8 and loading trucks with treated soil from Pile F. Crews loaded 9 trucks in the morning and 7 additional trucks in the afternoon, transporting treated soil from Pile F to Newton County Landfill in Brook, Indiana.
During all Site operations, START operated and maintained DataRam and Personal DataRam (pDR 1500) units to monitor all dust/particulates on and off Site. The personal data ram has been deployed to the cab of the excavator to monitor dust levels near on-site personnel. All personal data ram readings have been near or at back ground dust levels for the area (10-100 ug/m3). Average concentrations of dust have been 15-45 ug/m3. All site operations are being conducted using a water fog with a fire hose to minimize dust levels. The action level for nuisance dust is 500 ug/m3.
2.1.2 Response Actions to Date
US EPA's contractor Environmental Restoration is in the process of treating and excavating soil from 2 feet below ground surface to the original building's concrete foundation (approximately 5-5.5' below grade). Treated and excavated soil is being staged on the eastern edge of property for off-site disposal. Crews are then backfilling excavated areas with engineered sand. Top soil and seed will be graded on top of the sand fill to complete the site.
Samples collected from the treated soil and demolition debris were analyzed and results indicate that the constitutes of concern are under regulatory limits.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
The owner of the property has been identified, but has been non- responsive to repeated attempts to arrange for access to the property.
The U.S. EPA has obtained a warrant from a U.S. Magistrate to conduct the Site Assessment and Emergency Removal Action.
U.S. EPA has recently identified that an investment firm, Sabre Investments LLC, has purchased the back taxes for the property but has not yet filed the deed.
