Status

• A notice was published in the Capital Gazette newspaper on May 23, 2014, detailing the proposed Agency remedy decision. Minor comments were received on the proposed decision.
  The Final Decision for the site was signed by EPA on August 20, 2014. EPA's final remedy consists of requiring the Facility to maintain a groundwater monitoring program and to implement and maintain groundwater use restrictions through Institutional Controls (ICs).
• Corrective Action activities at the former Electro-Therm facility (Site), now owned by FIL [US] Inc. (FIL), are being conducted under the provisions of Maryland Department of the Environment (MDE) Consent Order No. CO-88-094 (CO), in cooperation with the United States Environmental Protection Agency (EPA) Region III. A site meeting between FIL, MDE, and EPA Region III was held on September 10, 2008, to discuss the steps needed to satisfy both regulatory programs. FIL submitted a work plan addressing the Site's remaining data gaps in 2009, and field work was conducted in 2010. MDE and EPA will be meeting with FIL in early 2013 to discuss any remaining data gaps and/or remedial endpoint strategies for the facility.
