PCB Soil Project


As a prime hazardous material consultant to the Virginia Department of Transportation (VDOT) since 2007, 3e has performed numerous property assessments and site investigations throughout the various VDOT Districts for a wide range of projects.  3e has extensive experience performing due diligence investigations in conformance with the ASTM E1527-13 and 1903-11 standards, which also includes incorporating the unique approaches for their successful completion in the context of transportation projects.  Project examples that demonstrate our understanding of these approaches are as follows: 

  • Hazardous Material Investigations and Special Provision Development for the 13th Street Roadway Improvement Project, Salem District (Roanoke, Virginia)
  • Due Diligence & Hazardous Material Investigations for the Rt. 757 Roadway Improvement Corridor, Bristol District (Wise, Virginia)
  • Phase I & II ESAs for Two Properties Considered for the Relocation of the VDOT Irving AHQ, Lynchburg District (Bedford County, Virginia)
  • 10th Street Roadway Improvement Project, Salem District (Roanoke, Virginia) 



3e has completed several remedial investigations and associated services at VDOT facilities (i.e. District Complexes & AHQ/Maintenance Shops) as well as at parcels acquired as right-of-way for pending/on-going roadway improvement projects.  Activities completed include but are not limited to petroleum UST/AST closures, removal/disposal of petroleum-impacted soil and groundwater, recovery of separate-phase petroleum from groundwater monitoring wells via aggressive fluid vapor recovery (AFVR), removal/disposal of impacted water/sediment from saltwater retention ponds, and groundwater sampling/analysis as part of SCR or corrective action monitoring activities.   Specific examples that demonstrate our VDOT-specific experience in these disciplines are as follows:

  • Remedial Activities for UST Release of No. 2 Fuel Oil for VDOT Bristol District Complex (Bristol, Virginia)   
  • 10th Street Roadway Improvement Project, Salem District (Roanoke, Virginia)
  • Petroleum-Impacted Soil & Groundwater Characterization and Abatement/Remedial Activities for the Rt. 29 Roadway Improvement Project (Gainesville, Virginia)



3e has completed SPCC Plans and associated 5-year updates for most of the Virginia Department of Transportation (VDOT) facilities statewide that are subject to the applicable requirements of 40 CFR Part 112.  We are familiar with the various facility operations and layouts, and understand the various types of ASTs/USTs typically present at these facilities that are regulated by the SPCC Rule.  Our staff includes two certified Steel Tank Institute SP001 inspectors that have an intimate knowledge of shop-fabricated ASTs, their associated components (secondary containment, overfill protection, venting, etc.), and how they are applicable to the various requirements of the SPCC Rule.  Their expertise also includes an understanding of the integrity testing requirements set forth by the SPCC Rule, which are governed by the tank construction (i.e. shop fabricated, field erected, steel, fiberglass, etc.) and modes of containment, release detection method, and spill control.

  • Under two Hazardous Materials contracts with VDOT, we have completed multiple ACM inspections for over 400 projects.  Structures surveyed for ACM largely included bridges (interstate to secondary roadways), asphalt AST systems, residential/commercial dwellings, and overhead fuel dispensers canopies. 
  • 3e has performed project monitoring services for regulated ACM abatement on structures associated with 24 roadway improvement projects.  Our licensed project monitors are familiar with the required elements of the pre-job submittals that are provided by the abatement contractors, which are reviewed to ensure that they meet the applicable regulatory requirements as well as the VDOT Road and Bridge Specifications.  We have proven to be nimble and typically can accommodate schedule changes that often occur when coordinating these projects through the VDOT-contracted abatement companies.
  • SPCC Plan Development or 5-Year Updates for over 80 VDOT Facilities (Statewide)
  • ACM Inspections for 86 Bridges (Bristol District, Virginia)

District Office of the Attorney General, Comprehensive Site Assessment, Washington, D.C.

Under contract with the District of Columbia Office of the Attorney General (OAG), 3e developed a Comprehensive Site Assessment (CSA) at the former Hess Terminal on Buzzards Point along the Anacostia River in Washington, D.C. The work was performed in accordance with current District Department of the Environment (DDOE) requirements and guidance.  Site investigations included delineation of free product plumes using laser induced fluorescence (LIF) survey at 53 points, installation of 9 groundwater monitoring wells, installation of 18 soil borings, comprehensive sampling of soils and groundwater, and aquifer testing.  Data analysis included hydrogeologic cross-sections, groundwater potentiometric surface and tidal interaction determination, and completion of the District of Columbia’s Risk Based Corrective Action (DCRBCA) analysis.  Results from the CSA and DCRBCA were used to develop remediation costs for both industrial and mixed-use redevelopment scenarios.  These projected costs were utilized by a third-party appraiser to establish fair market value for the property prior to DDOT acquisition for the replacement of the South Capitol Street Bridge over the Anacostia River.
