Status

• The Hoover Treated Wood Products, Inc. (Hoover) facility submitted a RCRA Facility Investigation (RFI) Phase II Report to DEQ in June 2012.  The Report focused on characterization of arsenic in groundwater on-site including potential impacts to surface water and sediments off-site and it detailed modifications made to the existing on-site groundwater recovery system. 
• Based on the information provided in the Report, Hoover began developing a Corrective Measures Study (CMS) in November 2012 to evaluate corrective measures for remediating arsenic in groundwater site-wide and to address arsenic detected in one sediment sample on the southern side of the facility where it meets the tidal wetland area.   
• DEQ anticipates that the final remedy proposed by Hoover at the end of the CMS process will utilize the existing groundwater recovery system.  The final remedy will be implemented under the facility’s existing Hazardous Waste Management Permit for Post-Closure Care and Site-Wide Corrective Action.

Background

• The Hoover facility occupies approximately 64 acres of property located in Milford, Virginia.  The facility lies within the Mattaponi River Basin, approximately one mile east of the Mattaponi River and is bound on the north by a low-lying marshy intermittent drainage way and on the south by tidal wetlands.
• Hoover produces pressure treated wood products using a chromate copper arsenate (CCA) solution and other wood treating solutions as well as interior and exterior fire retardants.  Historically, residual preservative materials were applied to the facility’s land after being mixed with a stabilizing agent.
• Building One, located on the northwest portion of the Hoover facility, was the location where residual wood preservative materials were treated, temporarily stored, and stabilized. Based on approved closure activities, clean closure of Building One, its contents, and the underlying unsaturated soils was successfully completed on December 1, 1999.
• Area A, located on the northeast portion of the Hoover facility, was the location where the stabilized residual wood preservative materials were deposited. Based on approved closure activities, clean closure of unsaturated soils in Area A was successfully completed on December 1, 1999.  However, clean closure of the groundwater could not be achieved.  Therefore, the post-closure care period for Area A shall continue until December 1, 2029.  Subsequently, on December 15, 2005, a Post-Closure Care Permit (Permit) for Area A including provisions for RCRA Site-wide Corrective Action was issued to Hoover by DEQ. 
• On July 18, 2006, DEQ completed an evaluation of available information and issued a “YES” determination for the “Migration of Contaminated Groundwater Under Control” Environmental Indicator (EI) in accordance with the Government Performance and Results Act (GPRA).
• On September 12, 2009, DEQ completed an evaluation of available information and issued a “YES” determination for the “Current Human Exposures Under Control” EI in accordance with the GPRA.
• On June 5, 2012, Hoover submitted a RCRA Facility Investigation (RFI) Phase II Report.  DEQ approved the RFI Report on August 3, 2012 and required Hoover to perform a CMS.

Contaminants and Risks

• The primary contaminants of concern (COC) include arsenic in groundwater site-wide with lesser concentrations of other inorganics at Area A.  Organic compounds have not been identified as a COC.
• Arsenic in one sediment sample adjacent to the property is being further assessed during the CMS process. 
• No impacts to air have been identified during the environmental investigations.
