Current Progress at the Site

Extensive progress has been made with the cleanup of the OSI Specialties, Inc. Site.  This facility is approximately 47 years old and is located, in Sisterville, West Virginia near the Ohio River.

In December 1990, EPA issued a RCRA corrective action permit to the company to proceed with site cleanup.  The permit was modified in 1997 to incorporate interim measures that the facility was initiating to address areas of contamination.  EPA and the facility worked jointly to complete the requirements of the permits which included:

The facility has completed the required corrective action measures and continues to monitor groundwater.  Additional monitoring wells have been installed at the request of the West Virginia Department of Environmental Protection.  The interim measures that have been implemented at the facility during the Corrective Action Program have been effective.  Therefore, EPA has proposed and selected, after Public Notice, the on-going Corrective Action Remedy as a final remedy for this facility.  The monitoring requirements of this Corrective Action Remedy have been incorporated into the new WVDEP RCRA Permit.
