Time Critical Removal Action
1.1.2 Site Description
Environmental Protection Agency (EPA) received a request from North Carolina Department of Environmental Natural Resources (NC DENR) to perform a Removal Site Evaluation (RSE) at the Ulah Battery Dump Site. The Site is located along 159 Dinah Road in Asheboro, Randolph County, North Carolina. NC DENR performed an assessment of the site. The state's analytical indicated lead concentrations up to 35,600 parts per million (ppm) in some areas. This exceeds the EPA residential Removal Action Level (RAL) of 400 ppm for lead due to the elevated concentrations of lead present in a residential area.
1.1.2.1 Location
159 Dinah Road, Asheboro, North Carolina 27203
1.1.2.2 Description of Threat
Lead and arsenic are present from battery cracking activities formerly performed at the Site. The facility was reportedly in operation from 1965 to 1981. Operations included hundreds of batteries being broken to remove the lead plates and melted in drums to be salvaged. Battery acid was reportedly allowed to spill onto the ground. EPA and Superfund Technical Assessment Response Team (START) site assessment on 04/01/2010 revealed XRF detections up to 59,700 ppm for lead and up to 3,735 for arsenic. The Site is a wooded area behind 159 Dinah road and bordered by a gravel road. Battery chips and casings were observed to be confined to a bermed area.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
During the week of July 18th, EPA conducted additional XRF analysis of the property at 159 Dinah Road. This parcel is approximately 140 feet by 280 feet and the front and back yards adjoing the wooded area in the southern half of the proiperty were subdivided into several managable grids for XRF investigation. In this manner EPA and Start found that lead levels in two grids of the front yard ranged from 400 - 1450 ppm lead, and four grids behind the home levels ranged from 397 - 2890 ppm. In addition, two grids in the back yard indicated elevated arsenic levels over 100 ppm arsenic. The driveway leading to the back of the home indicted lead levels approaching 3300 ppm lead.
To confirm these xrf readings, Start was tasked to collect ten samples for analytical analysis and the resulting analytical matched up well with the field results. XRF correlation ranged from 84.7 to 96.8%.
As previously indicted, lead levels in the dump area along the southern perimeter of the site range from 41,000 to 59,000 ppm lead.
