Identifying and implementing remedial solutions that minimize risk and get your property back to full use

We know that selecting and implementing a remedial technology can be one of the most important project decisions you will make. We routinely evaluate, select, and implement remedial strategies at sites ranging from fast-tracked, straightforward source excavations to complex, Superfund sites where several remedial solutions are required simultaneously. This diversity of project type and size makes us more versatile team members.

We believe that the right remedial approach considers the issues at your site – from the local geology and hydrogeology to your vision for development/redevelopment. We are committed to balancing these factors with your project objectives, including timeliness and overall cost. Our goal is to help you effectively get to project closure so that you can return your property to productive and valuable use while also minimizing risks to human health and the environment.

The BDM Warren Steel property is an approximately 1,200-acre brownfield that hosted steel-making operations beginning around 1912. 

This property changed ownership and names multiple times over the years and was known as Republic Steel Corporation, LTV Steel Company, WCI Steel, RG Steel, and BDM Steel.  Steel production at the mill has ceased and BDM demolished most of the buildings.  Verdantas was engaged to provide guidance and services in support of the site cleanup, restoration and permitting which occurred in multiple phases and is currently still in progress.

BDM invested private capital to demolish vertical structures, demolish building foundations and slabs.  They then recycled concrete for beneficial on-site reuse, and several thousand tons of steel was recycled.  Verdantas provided the oversite and guidance for the regulatory and permitting aspect of the project and completed the Phase I and Phase II Property Assessments and the Property Assessment Work Plans.  We also entered the site into the Ohio VAP (Voluntary Action Program) and MOA (Memorandum of Agreement) track.  The project was executed with the construction and remediation activities from the perspective of waste reduction, reuse, and recycling.

Verdantas also oversaw beneficial use and surface water impoundments closures in accordance with an approved Closure Plan that follows Ohio EPA Closure Plan Review Guidance for RCRA Facilities.  The related materials were reused in accordance with an Integrated Alternative Waste Management Plan (IAWMP).  These alternative management approaches to both the liquids and semi-solid materials located in the ponds resulted in the savings of over $5 million.

The Master Plan for the Lower Schuylkill River District is a blueprint for sustainable redevelopment of the industrial corridor along the east and west banks of the Lower Schuylkill River in Philadelphia. This public-private initiative was led by the Philadelphia Industrial Development Corporation (PIDC), the Philadelphia City Planning Commission and the City of Philadelphia Department of Commerce, with funding from the William Penn Foundation, the City of Philadelphia, and EPA Brownfield Grants.

“Bartram’s Mile,” a keystone of the Master Plan, is one mile of river frontage along the western banks of the Tidal Schuylkill between Grays Ferry Avenue and 58th Street. This portion of the Schuylkill River was cut off from public access for decades, thus representing an opportunity to not only link to Bartram’s Garden, the Schuylkill River Trail, and the 58th Street Greenway, but also add two new parks to be community assets for years to come.

Verdantas was the lead environmental consultant to the PIDC and Philadelphia Parks and Recreation in support of the Master Plan; specifically, the remedial design and cleanup oversight of two targeted Brownfield properties that flank Bartram’s Gardens to the north and south. These EPA Brownfield sites, Bartram North and Bartram South, are former bulk oil terminals that received product by barge and rail and stored millions of gallons of oil on-site. Soils and groundwater at these sites were significantly impacted by petroleum. With Verdantas' oversight, both sites have since received Act 2 liability protection for environmental conditions. In addition to environmental consulting services, Verdantas provided geotechnical, structural, and civil engineering services in connection with stormwater management, the assessment of the structural stability of an on-site dock, construction of a shade structure at Bartram South, and a FEMA floodplain analysis. Bartram’s Mile opened in April 2017 providing the community a space for walking, biking, running and bird watching.

We were recommended by an attorney to the owner of a strip mall to define the extent of a chlorinated volatile organic compound (CVOC, primarily tetrachloroethene or [PCE]) plume and implement a long-term remedial strategy without disrupting multiple tenant business operations.

Achievements

  • Excavated accessible CVOC – and fuel oil-impacted soil.
  • Worked with existing business operations to remediate without disruption of business. We installed soil borings inside a pharmacy during off-hours to assess impacted inaccessible soils.
  • We completed indoor air evaluations and risk assessments to evaluate needs for additional remediation and to assess tenants who were not exposed to inhalation risk during remediation. Furthermore, we implemented a periodic indoor air monitoring plan to evaluate ongoing tenant and public exposure.
  • Evaluated potential risks for neighboring properties. We evaluated the downgradient property for potential vapor intrusion impacts while considering proposed site redevelopment plans.
  • Advised our client and their legal counsel on the long- and short-term remedial strategies that allowed the client to plan and budget, while also meeting New Hampshire Department of Environmental Services (NHDES) standards.
  • Continue to manage ongoing requirements associated with the Site’s Groundwater Management Permit.

Scope of Services

  • Site Characterization of CVOC plume
  • Short- and long- term remedial strategy development and implementation
  • Coordinate with client and client’s legal team
  • Complete remediation of CVOC impacts
  • Indoor air assessment
  • On- and off-site vapor intrusion evaluations
