Project Navigator, Ltd.’s Land Navigator, LLC is a “Boneyard Site Holding Entity” for Mature, Low Risk CERCLA Sites

Boneyard concept overviewClients are thinking about what happens after 30 years of EPA enforcement activities, routine OM&M and the attainment of all remedy performance goals. Land Navigator’s operations leverages many of the ideas described in U.S. EPA’s 2017, 90-Day Superfund Task Force Report.



  • 30 Years is Up…What’s Next?
  • Mature CERCLA Sites & Their OM&M
  • EPA’s Receptivity to Alternate Stewardship Approaches
  • Termination of Original CDs or UAOs & Entry into a New Program
  • A Feasibility Evaluation
  • Facilitated Group Planning Sessions
  • Visioning Meetings with U.S. EPA

With CERCLA enacted nearly 40 years ago, many sites have been investigated and cleaned up and have now been under decades of OM&M. With the many consent decrees (CDs) and unilateral orders (UAOs) for response actions possessing a somewhat arbitrary O&M timeframe of “30 years”, the question of “what happens after 30 years?” is being evermore posed by major PRPs. What is and how can we reach an “end or exit or reset” from the clutches of the Superfund program?

With today’s U.S. EPA evaluating CERCLA program changes through the Superfund Task Force, now is an ideal time to evaluate alternative methods to more cost-effectively manage mature Superfund sites (even by possibly having them exit the original program?).

Our sister company Project Navigator, Ltd. (PNL) ( has been interacting with clients and U.S. EPA on how appropriately selected, mature, stable, low risk sites could be more cost-effectively stewarded if they were “legally transferred” into a “boneyard, site-holding” entity…such as Land Navigator, LLC.

The proposed Boneyard entity would be responsible for OM&M (and further aggressively right-sizing such activities), and assuming title, where applicable. The Boneyard entity would also seek site reuse options, an approach which is very much in accord with the recommendations described in 2017’s U.S. EPA Superfund Task Force, 90 Day Review Report. Internally, companies will no longer need to track and provide administrative oversight, further reducing any individual PRPs’ spend.

Sites transferred into the Boneyard will have completed all site compliance remedial activities, except for the tail of routine, repetitive, OM&M activities. Such conditions may allow the original CD/UAO to be terminated, allowing future site (think “just land”) stewarding to occur far more simply outside the formalities of historical CERCLA.

Mature “OM&M-Predictable” CERCLA Sites, Where CD/UAO Performance Goals Have Been Attained, Could Be Managed under “Site Boneyard” Holding Management Structure

Benefits, Yet To Be Refined via a Feasibility Evaluation, Could Include: Termination of Existing Enforcement Agreements with U.S. EPA; Site Title Transfer into the Boneyard Entity; Focused and Reduced OM&M Activities & Improved Cost-Effectiveness.
