  • Provide environmental support for real estate transactions, including environmental investigations and assessments, reviewing due diligence documentation, negotiating appropriate transactional terms and conditions, and advising on waste management and disposal needs.
  • Offer a level of expertise with the environmental issues common to the telecommunications, electrical and chemical manufacturing, solid waste and recycling, government contracting, ordnance/munitions/explosives, agricultural, and petrochemical industries. Represent clients in environmental enforcement, cost recovery, contribution, allocation, toxic tort, regulatory, citizen suit, and common law actions.
  • Served as coordinating counsel for PRP outreach, initial allocation and administrative settlement negotiation at Illinois CERCLA site – efforts expanded the Group from 39 to 162 member companies and resulted in a signed RI/FS ASAOC for the site.

  • Assist numerous real estate clients with Phase I and Phase II environmental due diligence assessments, investigative sampling, and remediation efforts, with particular focus on the environmental consultants’ contract terms, the future use of the property, and cost-efficient, timely methods to determine if the property is appropriate for the clients’ intended uses.
  • Represented three potentially responsible party (PRP) plaintiffs in a Southern District of Illinois multi-million dollar contribution case involving a secondary lead smelter; pre-litigation settlement offer process resulted in approximately $4.3 million in proceeds from several dozen PRPs in return for $600,000 investment of transaction costs (7:1 rate of return for costs recovered).

  • Negotiated an early settlement with a co-party at a waste disposal site which allowed the co-party to pay property sale proceeds over to the other parties who used the disposal site and thereby created an immediate tax deduction, which allowed the co-party to use the sale proceeds for site cleanup instead of tax liabilities. Retained as common counsel for cost recovery and contribution cases, focusing on pre-litigation and post-litigation settlement processes to create cost-effective options for resolving liabilities.
