Prior to EPA involvement at the Facility, Hercules closed some units or solid waste management units (SWMUs) under Virginia Department of Environmental Quality (VDEQ) direction. In October 1999, Hercules agreed to conduct further environmental investigation and clean-up under a Facility-Lead Agreement with EPA to satisfy RCRA Corrective Action Program requirements. In October 2010, Hercules entered into a RCRA 3013 Order on Consent with EPA to finish Corrective Action at the Facility
Hercules investigated contamination from chemical releases as documented in the Release Assessment (ERM; March 1999) and the Release Assessment Addendum (GES; January 2002). Site-related contaminants were identified in soil and groundwater and include: 1, 2 -dichloropropane (PDC), benzene, acetone, heptane, phenols, petroleum hydrocarbons, polynuclear aromatic hydrocarbons and organic peroxides.
Remediation of organic peroxides (by air-sparging) in groundwater at one unit is on-going. Hercules completed groundwater sampling of private wells located around the facility and found no site-related compounds. In 2010, Hercules stabilized, excavated and removed the sludge in the former waste pits and lagoon in the West Area. A final remedy decision for the Facility will be made after Hercules submits a Corrective Measures Study to EPA in 2015.
The Facility has been a chemical processing plant producing rosin, fatty acids and organic peroxides since 1955. The primary raw material used was 'tall oil', also called liquid rosin, derived from trees (mostly pine) during the wood pulping process. Historically, Hercules managed wastes on-site in landfills, a spray field, lagoons and pits, but discontinued these waste disposal methods and upgraded waste handling. The current processes generate wastewater, non-contact cooling water, biological sludge and some spent solvents (from the on-site quality control laboratory). The wastewater treatment plant was upgraded and produces little sludge, which is shipped off-site under VADEQ permit. The former pits, lagoon and sprayfield were closed after the sludge was stabilized and removed to an off-site commercial landfill in 2010.
In 2001, Hercules began selling some manufacturing units at the Facility, while retaining ownership of the property and responsibility for past site releases. In 2008, the tall oil distillation process at the Facility was discontinued.
