2.1.1 Narrative
2.1.2 Response Actions to Date
On 8/3/2016, the Emergency and Rapid Response Services (ERRS) contractor CMC, Inc. began clearing and soil excavation activities. The soils are placed in two separate stockpiles, based on use of an X-Ray Fluorescence (XRF) which measures total arsenic concentrations. The Superfund Technical Assistance and Response Team (START) contractor delineates areas at the surface with the XRF where total arsenic concentrations soils are >5,000 parts per million (ppm). Using historical data collected from this site, these soils are likely to fail the Toxicity Characteristic Leaching Procedure (TCLP) and are managed as a hazardous waste. These soils will be shipped to a RCRA Subtitle C landfill in Indianapolis, IN for disposal. Soils which test below 5,000 ppm are placed in a separate stockpile and will be shipped as a DOT hazardous material to the Republic Services Ohio County landfill in Beaver Dam, KY. As of the date of this report, approximately 2570 cubic yards of arsenic-contaminated soils have been excavated and stockpiled.
Off-site disposal of the DOT-regulated materials began on 09/14/2016, and as of the date of this report, over 280 tons has been disposed of at the Ohio County landfill.
On 08/30/2016, air samples were collected to evaluate the potential exposure of site workers to airborne arsenic particulate matter. The results indicated that the maximum arsenic concentrations detected were 1.2 micrograms per cubic meter of air (ug/m3). This is below the OSHA limit of 10 ug/m3 by an order of magnitude. Site workers continue to wear Level C respiratory protection until another round of samples is collected to justify a downgrade in personal protection.
Also during this reporting period, additional funding in the amount of $900,000 was placed on the ERRS Task Order..
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
All of the previous and current land owners have been designated as PRPs for this Site. However, none have been identified for purposes of conducting the removal action as there is no direct evidence that any of the land owners contributed to a release of hazardous substances during their period of ownership.
Wells Fargo N.A. is currently responsible for the Wiley property but is not considered a PRP because
it acquired title to the property via a foreclosure proceeding and thus has no
liability under CERCLA.
