Project Navigator, Ltd.’s Houston Staff Describe a New Management Approach for the Stewardship and Operations, Monitoring & Maintenance (OM&M) of Long-Closed, Superfund (CERCLA) Sites

PNL has worked for PRPs managing environmental response actions at Gulf Coast CERCLA sites since the company’s founding 21 years ago. Major, complex CERCLA remediation programs under PNL’s direction, such as Malone, Tex Tin and PAB Oil & Chemical have run from their early RI/FS stages, to RODs, to RD/RAs and now into their respective long-term OM&M phases. However, with recognition that PRPs (1) still require an entity cost-effectively to “steward compliance” where major investments have been made, while (2) simultaneously seeking opportunities to develop a “consent decree-walk away-end game” solution, PNL has been interacting with PRPs and U.S. EPA Region 6 in the planning of a Long-term Site Management Entity. This month PNL hosted webinars on the topic with over 30 major companies participating. During 2019, PNL will continue to refine this new mature CERCLA site management system, further involving PRPs and EPA, while especially recognizing how many of the recommendations from EPA’s Superfund Task Force can be put into action via the proposed entity. Many of the “entity’s key factors” such as site title transfer, liability management, legal and regulatory compliance, and OM&M reporting, which could be managed via PNL’s Land Navigator, LLC.

Project Navigator, Ltd. Presents at AEHS Annual Conference in San Diego

Project Navigator, Ltd.’s Robert Fritz presented a poster on solar facilities on landfills, brownfields and Superfund sites at the March 2018 AEHS Winter Meeting in San Diego, CA.

PNL works with our sister company TerraNavigator, LLC on the conception, planning and development of utility scale solar power projects on landfill sites.
