Hazardous Waste Cleanup: Ashland Specialty Ingredients (Formerly: Hercules Incorporated - Hopewell Plant) in Hopewell, Virginia

On this page:


In 2000, Hercules and the EPA entered into a Facility Lead Agreement (FLA) for the implementation of Corrective Actions under Resource Conservation and Recovery Act (RCRA).

    Cleanup Status

    Hercules submitted the RCRA Facility Investigation (RFI) Summary Report in November 2011. The RFI Summary Report includes the Human Health Risk Assessment and the Baseline Ecological Risk Assessment as Attachments A and B respectively. EPA approved the RCRA Facility Investigation Summary Report in a letter dated March 27, 2012. Hercules submitted the Corrective Measures Study in April 2014. EPA prepared a Statement of Basis, which documents the proposed remedy for the site. The Statement of Basis went out for public comment during the month of June. The Final Decision and Response to Comments (FDRTC) was signed by EPA's Director of Land and Chemicals Division on July 22, 2015. The selected remedy calls for Institutional controls, restriction on groundwater use and continual maintenance of the existing security fence. Hercules will use the Virginia Uniform Environmental Covenant Act (UECA) to link the institutional controls to the property.

      The Hercules Aqualon site occupies a 390-acre parcel of land in Hopewell, Virginia and employs about 400 local residents. Hercules purchased the property in 1926 but the site has been used for industrial purposes since 1912 under various owners/operators. The Hercules Hopewell Plant is one of the largest cellulose derivative production facilities in the world. All of the finished products are based on cellulose, a raw material that comes from trees or cotton. The cellulose is swollen with sodium hydroxide (caustic) and reacted with one or more chemicals, depending on the product being manufactured. The resulting product is then purified, dried, and packaged.
