An Environmental Indicator (EI) inspection was conducted at the Conversion Systems facility (Facility) in August 2007.  All areas where hazardous waste was handled appeared well-maintained; no evidence of spills or releases were apparent. 

The EPA has determined that the Facility met the current human exposures under control indicator on December 27, 2011.  The EPA has determined that the Facility met the migration of contaminated groundwater under control indicator on December 27, 2011.  In January 2012, EPA issued a Final Decision of Corrective Action Complete without Controls for the Facility.

Pennsylvania Department of Environmental Resources (PADER) confirmed the closure of their 2500 gallon underground holding tank during a May 23, 1984, PADER inspection.  A closure plan was submitted to PADER in November 1983.  PADER approved closure on April 1985.

A letter from USEPA contractor NUS to USEPA, dated September 27, 1990, recommended that no further action be taken at the Site under CERCLA.
