Case Studies: Environmental Liability & Asset Management

The EXCALIBUR partners / staff are proud to have been part of the following asset & environmental liability management projects exemplifying the experience EXCALIBUR personnel bring its clients in this area.

Case 1: Strategic Corporate Asset Management – Multinational, Multiple States

EXCALIBUR works for one of the world’s largest multinational companies headquartered in Tokyo, providing strategic senior-level asset and environmental liability management advice and services concerning portfolios of legacy environmental liabilities and other investments throughout the United States and Canada. EXCALIBUR also closely works with the corporate client and their legal advisors to assess the operations, compliance status, contamination liabilities, and on-going environmental engineering and site cleanup efforts at scores of industrial, waste management and disposal sites across the United States.

Case 2: Asset & Environmental Liability Management for Investment Bank

In the process of foreclosing on environmentally impaired assets in its $2 billion loan portfolio of over 3,000 commercial properties, EXCALIBUR’s client has acquired certain site and environmental liabilities requiring careful and systematic management. EXCALIBUR serves as the lender’s environmental liability & asset manager / senior technical advisor, providing critical information on known site conditions, compliance, and other factors important in the investment bank’s compliance with applicable regulations and in business decisions.

Case 3: Re-designation of Impacted Industrial Legacy from a Liability to a Commercial Asset, Cleveland, Ohio

For a 12-acre legacy, “flat-lotted” industrial RCRA Corrective Action site with residual coal tar and other contamination, EXCALIBUR provided site management, site security, regulatory interface, community outreach, environmental consulting, investigative, compliance, and remedial design review, engineering and other support services to assist the client in meeting their ultimate goal of obtaining the Ohio EPA’s approval that all of the state’s and US EPA’s RCRA Corrective Action requirements had been met, thereby opening the door to site sale, leasing and/ or re-development.

Case 4: Former Coal Tar Refining Superfund Site in Eastern Ohio

A multi-national chemical manufacturer retained EXCALIBUR to manage a vacated eastern Ohio legacy coal tar Superfund site and its associated environmental liabilities. EXCALIBUR took over site security, remedial system O&M, engineering, consulting regulatory compliance reporting, river sediment sampling / investigation, the USEPA 5-year review process and other actions dictated by the USEPA and Ohio EPA-enforced Consent Decree and Long-term Monitoring Plan (LTMP) applicable to the client’s Superfund site. This transition had been precipitated by USEPA criticism of the existing engineering contractor deemed unresponsive to key compliance needs.

Case 5: Strategic Compliance, Engineering, Remediation Support, US EPA Superfund Coal Tar Refining Site, Multinational Special Chemical Manufacturer, WV

EXCALIBUR provided technical and strategic insights to corporate environmental management and legal leaders to manage environmental liabilities associated with a 20-acre former industrial site including an impacted adjacent river and for a site that was subject to investigation and cleanup under the US EPA Superfund program. Providing critical regulatory support in negotiations related to the need for site remedial action, particularly on how to address free phase coal tar groundwater contamination, was a key objective. Focus on defining, implementing and monitoring creative options was another priority with the capture and treatment of impacted groundwater using coordinated engineered collection and treatment systems designed to treat millions of gallons of contaminated ground water and eliminate oily discharges to receiving streams.

Case 6: Hazardous Waste Landfill Superfund Site, OH

Since 2010, EXCALIBUR has been managing a western Ohio hazardous waste landfill Superfund site and associated long term environmental liabilities. EXCALIBUR is serving multiple PRPs by cost effectively managing all aspects of the Superfund site and its liabilities including maintaining site security, O&M of the leachate recovery and treatment system, monitoring of landfill and sentinel well groundwater, landfill gas sampling and evaluation, database development, landfill cap integrity maintenance and inspection, data management and analyses, USEPA and OEPA regulatory interface and reporting, human health risk assessment and other such Superfund site management activities. On behalf of the PRPs as a major initiative to significantly reduce current and future long-term costs by an estimated $2M cumulative, EXCALIBUR is currently preparing a petition to the agencies to idle the labor intensive leachate collection and treatment system based on improved site conditions and current/future projected human health risks.

Case 7: Management of Underground Storage Tank Assets for High-Visibility School District Program

In concert with the U.S. Army Corps of Engineers (USACE) Baltimore District Total Environmental Restoration Contract (TERC), EXCALIBUR prepared a series of detailed written technical plans needed to efficiently and safely remove fuel product from a significant number of underground storage tanks (USTs) serving the Washington DC public school system. These pre-requisite project documents accounted for evacuating and assessing 124 USTs ranging in size from 1,000 to 40,000-gallons at 116 active District of Columbia, Washington, DC, Public School System (DCPS) sites. EXCALIBUR prepared the following plans under a fast-track schedule: a comprehensive Health and Safety Plan (H&SP); a detailed Contractor Quality Control Plan (CQAP); a Comprehensive Site Assessment Work Plan (CSAWP); and a Site Specific CSAWP (as a working example for all facilities within the school system).
