“Bering Sea Eccotech, Inc coated the lead painted exterior siding and a small area inside the south east corner of the building with LeadDefender®, which is designed to bind with lead in the paint and render it less soluble. Previous samples of the paint in these two areas had failed the TCLP limit of 5.0 mg/L for lead. The siding and the material from the interior painted walls would have required handling as a RCRA hazardous waste if they had been removed from the building in that condition…BSE collected samples from the exterior siding and the interior wall materials after coating them with LeadDefender®. These were analyzed by the TCLP and found to no longer exceed 5.0 mg/L, and thus would be a non-hazardous solid waste if removed and disposed. At this point, demolition of the building proceeded…” National Oceanic and Atmospheric Administration (NOAA), Office of Response and Restoration; Municipal Garage Demolition and Contaminated Soil Removal, St. Paul Island, Alaska
