This report presents the methods and findings of a Phase II Environmental Site Assessment (ESA) performed at the Central Virginia Training Center (CVTC), currently owned by the Commonwealth of Virginia under the Department of General Services. The Virginia Department of Behavioral Health and Developmental Services (DBHDS) is studying the feasibility of placing CVTC in a surplus property status.

This Phase II ESA was prepared to assess the presence or absence of contaminants in soil and groundwater from the high and medium priority findings presented in the Site Specific Environmental Conditions Assessment (ECA) that was performed by EEE Consulting, Inc. (3e) in July 2017.

A total of 19 separate areas (or Findings) were assessed, with the following results:

• ECA Finding #10 (former Physical Plant and Laundry): No impacts from the former Physical Plant were found in soil or groundwater (current location of Building 47).

• ECA Finding #11 (former Coal Powered Incinerator - Building 13): no impacts warranting additional assessment.

• ECA Finding #12 (former Medical Waste Incinerator in New Scrap Yard): no impacts warranting additional assessment.

• ECA Finding #13 (Closed Sanitary Landfill): recommend eligibility determination and enrollment into the Virginia Department of Environmental Quality’s (DEQ) Voluntary Remediation Program (VRP) because this area of CVTC was utilized for historical landfilling operations. Installation of additional monitoring well(s) on adjoining property and other work as may be required to obtain a Certificate of Completion.

• ECA Finding #14 (New Scrap Yard): recommend eligibility determination and enrollment into the VRP because of site conditions indicative of landfilling operations.

• ECA Finding #15 (Coal Ash and Debris Dump): recommend eligibility determination and enrollment into the VRP because of site conditions indicative of landfilling operations. Remove discarded debris and dispose in accordance with applicable regulations.

• ECA Finding #16 (Old Scrap Yard): recommend eligibility determination and enrollment into the VRP because of site conditions indicative of landfilling operations.

• ECA Findings #20 and #27 (Bulk Pesticide and Oil Storage in Building 39): recommend demolition of the building in a manner to minimize impacted soil disturbance. Subsequent excavation of impacted soil from grade to two (2)-ft. BGS. Eligibility determination and enrollment to complete these activities under the VRP because of the confirmed impacts to soil from detectable hexavalent chromium, lead, banned pesticide, and petroleum concentrations.

• ECA Finding #21 (former Transformer Storage): no polychlorinated biphenyl (PCB) impacts detected, nor any other impacts warranting additional assessment.

• ECA Finding #28 (Suspect Fuel Oil Storage at Building 53): encountered fill material and low levels of residual-phase petroleum that are likely associated with a former underground storage tank (UST). Recommend reporting a petroleum release to the DEQ-Blue Ridge Regional Office (DEQ-BRRO), who will likely recommend site closure without additional assessment activities.

• ECA Finding #29 (Diesel Fuel UST at Building 46): no petroleum impacts found, perform UST closure and reporting in accordance with 9VAC 25-580 (i.e. Virginia UST Regulation) when no longer in use.

• ECA Finding #30 (Gasoline UST and Diesel AST at Building 36): Trace concentrations of gasoline indicator compounds were detected in groundwater. It is recommended that groundwater be resampled to confirm the presence of petroleum indicator compounds. If present, a petroleum release should be reported to the DEQ-BRRO.

• ECA Finding #31 (Diesel Fuel UST at Building 65): no petroleum impacts detected, perform UST closure and reporting in accordance with the Virginia UST Regulation when no longer in use.

• ECA Finding #32 (Diesel Fuel UST at Building 47): no petroleum impacts detected, perform UST closure and reporting in accordance with the Virginia UST Regulation when no longer in use.

• ECA Finding #33 (Diesel Fuel UST at Building 31): no petroleum impacts detected, perform UST closure and reporting in accordance with the Virginia UST Regulation when no longer in use.

• ECA Finding #35 (Former Gasoline UST at Building 49): no petroleum impacts detected, no additional assessment warranted.

• ECA Finding #36 (Unknown Drum and Spilled Material at Building 45-5A): drum was removed and disposed by facility personnel prior to the implementation of Phase II assessment activities. Spilled material and soil was excavated and drummed for disposal. Toxicity sampling indicated the drum of excavated material was hazardous for lead, and the drum was subsequently disposed as hazardous waste.

• ECA Finding #38 (Drum of Compressor Oil at Building 30): drum was removed and disposed by facility personnel prior to the implementation of Phase II assessment activities. Spent oil dry on the floor was sampled and did not contain PCBs. No additional assessment warranted.

The following cost estimates for additional assessment, characterization, and/or remediation work are provided for DGS fiscal planning and appropriation of funding sources. These range of costs are based on recommended activities, our experience with the VRP, and typical industry standard rates. They are not intended to be used as a proposal cost to complete the work.

• ECA Finding #13 (Closed Sanitary Landfill): The range of costs to manage this Finding through the VRP is estimated at $100,000 to $150,000 for all tasks except removal/disposal of surface wastes and any required improvements to the existing landfill cap.

• ECA Finding #14 (New Scrap Yard): The range of costs to manage this finding through the VRP is estimated at $80,000 to $100,000 for all tasks except removal/disposal of surface wastes and any required improvements to the existing landfill cap.

• ECA Finding #15 (Coal Ash and Debris Dump): The range of costs to manage this finding through the VRP is estimated at $25,000 to $50,000 for all tasks except removal/disposal of wastes.

• ECA Finding #16 (Old Scrap Yard): The range of costs to manage this finding through the VRP is estimated at $80,000 to $100,000 for all tasks except removal/disposal of surface wastes and any required improvements to the existing landfill cap.

• ECA Findings #20 and #27 (Bulk Pesticide and Oil Storage in Building 39): The range of costs for excavation, sampling, and disposal of impacted soil is estimated at $80,000 to $150,000. This estimated cost range is dependent on the waste characterization to determination the appropriate disposal option(s) for the excavated soil. The provided range of costs includes all tasks except groundwater characterization activities as required by VRP, if any. If required, these activities would likely cost an additional $12,000 to $15,000, depending on the depth to groundwater.

• ECA Finding #28 (Suspect Fuel Oil Storage at Building 53): Release reporting and management of a petroleum release, under the assumption that the DEQ-BRRO will not require further assessment activities, is estimated to cost $1,000.

• ECA Finding #30 (Gasoline UST and Diesel AST at Building 36): Groundwater resampling and follow-up petroleum release reporting, if required, is estimated to cost $3,000.

Based on the provided estimates, the range of cost to manage these Findings through the VRP is estimated at $369,000 to $569,000. This range does not include the removal/disposal of surface debris and emergent or dumped debris within the landfill and scrapyard areas, nor does it include any improvements that may be required to supplement the existing landfill caps.

This Phase II ESA assessed those Findings classified as high and moderate risk to third party (offsite) receptors, human health and the environment. The remaining Findings presented in the July 2017 ECA will require assessment and/or management as part of facility closure; however, many of these Findings are associated with processes currently in use (e.g. the 90,000-gallon heating oil AST at the boiler plant, USTs currently in use, etc.). There will be future environmental management costs associated with these findings, which should be assessed if/when the associated structures are demolished and/or removed from the site.
