2.1.1 Narrative
On August 5, 2013, crews loaded trucks with treated soil from Pile A and shipped off-site for disposal. Crews also worked to treat impacted soil from west end of site with Free Flow fixating agent and stage mixed material on site as Pile B.
On August 6, 2013, crews continued to load trucks with treated soil from Pile A and shipped off-site for disposal. A total of 14 loads were shipped out for disposal. Crews also worked to treat impacted soil with Free Flow fixating agent and stage mixed material on site as Pile B.
On August 7, 2013, crews loaded trucks with treated soil from Pile B and shipped off-site for disposal. Crews also worked to treat impacted soil from west end of site with Free Flow fixating agent and stage mixed material on site as Pile C.
On August 8, 2013, crews loaded trucks with treated soil from Pile B and shipped off-site for disposal. Crews also worked to treat impacted soil from west end of site with Free Flow fixating agent and stage mixed material on site as Pile C. START collected a composite and submitted a sample of Pile C material for laboratory analysis to facilitate disposal approval. ERRS has 8,020 pounds of lead metal debris removed from the site for recycling with a local metal recycling firm.
During all Site operations, START operated and maintains DataRam and Personal DataRam (pDR 1500) units to monitor all dust/particulates on and off Site. The personal data ram has been deployed in the cab of the excavator to monitor dust levels for 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.
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.
