This CLE course will provide guidance for environmental counsel representing companies planning, implementing, maintaining and enforcing long-term stewardships (LTS) at contaminated sites to minimize legal risks.


Potential long-term stewardship (LTS) obligations often flow from residual contamination. These obligations frequently center on the vapor intrusion pathway. Vapor intrusion (VI) is the migration of volatile chemicals from contaminated soil and groundwater into buildings. This evolving inhalation “pathway” presents significant challenges and complicates environmental remediation and Brownfield development projects, real estate transactions, and management of commercial/industrial real estate portfolios.

The U.S. EPA has recently updated its national Institutional Control (IC) Policy which provides important guidance for investigation and remediation, and ultimately closing, contaminated sites. The updated IC Policy outlines an approach to help meet potential LTS obligations for managing residual risk and achieve site closure. The U.S. EPA has also made significant revisions to its draft 2002 national VI guidance and is very close to releasing this new guidance document.

LTS is an increasing part of cleanup programs in order to get contaminated properties ready for beneficial reuse. Ongoing monitoring and maintenance (especially foe the VI pathway) is needed to ensure continued protection of the human health. Environmental counsel to companies need to understand the legal risks from the contaminated sites, when and how to implement LTS, what needs to be done to ensure LTS obligations are met, and the new LTS tools available to tailor a site-specific approach.

Listen as our panel of experts examines LTS and what that includes from a monitoring plan to reporting requirements. The panel will discuss the viability of remedies and management of ongoing and future risks at contaminated sites as well as change of ownership issues that arise when contaminated property exchanges hands. The panel will offer best practices for implementing, maintaining and enforcing a LTS plan.



  1. LTS
    1. Threshold criteria
    2. Controls
    3. Monitoring plan
    4. Recording keeping, reporting requirements
  2. Mitigation remedy
  3. Management of ongoing risks
  4. Change of ownership issues


The panel will review these and other key questions:

  • What factors should counsel consider when determining which LTS tools are to be implemented?
  • What steps can counsel recommend to ensure LTS measures are effective and meet compliance requirements?
  • What framework does the EPA guidance provide to ensure the requirements for implementing LTS are met?
