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.

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

The Philadelphia Authority for Industrial Development (“PAID”) received funding from the USEPA to establish a new revolving loan fund (“RLF”) for brownfield remediation in Philadelphia. The Philadelphia Industrial Development Corporation (PIDC) administers the RLF on behalf of PAID. The revolving loan fund is intended to support brownfield remediation projects within the City of Philadelphia, specifically focusing on the 3,700 acre industrial corridor known as the Lower Schuylkill. PIDC selected Verdantas to provide environmental engineering and professional services for high-quality technical assistance, advisory services, regulatory coordination and project oversight to support the successful administration of the program. Verdantas, in support of PIDC’s administration of the program developed the following: application document templates; assisted with the development and implementation of a marketing program to solicit applications; assisted PIDC with the development of an applicant ranking system; reviewed applicant eligibility based on the requirements of the EPA and PADEP; and provided oversight of awardees, including review of progress reports. Verdantas also completed the reporting required by the EPA’s ACRES system. Verdantas was recently presented with the 2017 Phoenix Award for U.S. EPA Region 3 at the 2017 National Brownfields Conference for our Pennovation Center project performed for the Philadelphia Industrial Development Corporation. The Phoenix Awards are recognized nationally as the award for outstanding achievement of excellence in brownfield redevelopment.
