Superfund and climate change

PNL has noted recent news about a mid-October 2019 GAO report titled EPA Should Take Additional Actions to Manage Risks from Climate Change. The report evaluated the potential for adverse climatic effects on Superfund sites in terms of flooding, storm surge, wildfires, and sea level rise. Each individual Superfund site in the US is evaluated and rated for its potential impact by location. Data included the FEMA National Flood Hazard Layer for flood hazards, the NOAA SLOSH Model for storm surge, a NOAA SLR Model for sea level rise and the U.S. Forest Service’s wildfire hazard potential map. PNL reviewed the report and we provide a brief summary.

Report Summary

The GAO report concludes:

  • “Climate change may increase the frequency and intensity of certain natural disasters, which could damage Superfund sites-the nation’s most contaminated hazardous waste sites.
  • Federal data suggests about 60 percent of Superfund sites overseen by EPA are in areas that may be impacted by wildfires and different types of flooding-natural hazards that may be exacerbated by climate change.
  • We (GAO) found that EPA has taken some actions to manage risks at these sites. However, we recommend it provide direction on integrating climate information into site-level decision making to ensure long-term protection of human health and the environment.”

The GAO Report recommendations include:

  • Recommendation 1: The Director of the Office of Superfund Remediation and Technology Innovation should establish a schedule for standardizing and improving information on the boundaries of nonfederal NPL sites.
  • Recommendation 2: The Administrator of EPA should clarify how EPA’s actions to manage risks to human health and the environment from the potential impacts of climate change effects at nonfederal NPL sites align with the agency’s current goals and objectives.
  • Recommendation 3: The Director of the Office of Superfund Remediation and Technology Innovation should provide direction on how to integrate information on the potential impacts of climate change effects into risk assessments at nonfederal NPL sites.
  • Recommendation 4: The Director of the Office of Superfund Remediation and Technology Innovation should provide direction on how to integrate information on the potential impacts of climate change effects into risk response decisions at nonfederal NPL sites.

Future Considerations

In the future, to address potential climate change issues for affected sites:

  • The design of the remedy will consider the potential effects of climate change.
  • The remedy will be closely monitored to ensure the effectiveness the remedy over time.
  • The PRPs are funding the design and construction of the remedy and it is the PRP’s best interest to ensure the remedy is designed for appropriate future conditions.
  • EPA has released a Climate Change Adaptation Technical Fact Sheets for Contaminated Sediment Remedies. PNL would suggest that we would follow USEPA’s guidance to identify, prioritize, and implement site-specific measures for increasing remedy resilience to climate change effects.

The COVID-19 virus situation

Dear Friends, Colleagues and Business Partners,

Project Navigator, Ltd. assures you that we take the health and well-being of our work environment and community very, very seriously.

All PNL staff are closely monitoring the quickly developing effects of the Coronavirus (COVID-19), and are advising clients, fellow consultants and contractors on how to perform on a site-by-site basis. More on PNL’s approach to determining what work is “absolutely essential” is described here.

To assist in slowing the spread of COVID-19, PNL staff will: 1. practice social distancing and telecommuting and 2. Manage and oversee field work activities on a project-by-project basis, which are consistent with the ever-evolving best practices. While our office is closed, our business activities are still running.

We will continue to monitor the COVID-19 situation and will stringently follow guidance from public health officials and government agencies (esp. at ), so we can continue to support our clients, work-partners and the communities in which we live and work.

Project Navigator, Ltd. develops Removal Action Plan for lead-impacted smelter residues for City of Cherryvale

Project Navigator, Ltd. (PNL) performed work as the on-site construction oversight contractor and client representative for the remediation of the former National Zinc smelter site which was operated under the Kansas Department of Health and Environment (KDHE) Voluntary Cleanup Program. Work involved excavation and consolidation of approximately 100,000 cubic yards of metal impacted slag in an onsite disposal area and backfill of the excavation with clean fill obtained from nearby borrow sources.

After the smelter site remediation was completed, lead-impacted smelter residues were discovered in multiple locations within the City of Cherryvale where over the years, material was used for construction fill and road base. At the direction of the clients and under oversight of KDHE, PNL mobilized to investigate the nature and extent of smelter residues within the City. Working with the clients, KDHE and other contractors preparing plans and risk assessments, PNL organized and trained local teams and devised the program to obtain access to 100’s of properties, mapped, categorized, sampled and performed thousands of analyses in the field using portable XRF technology. This work resulted in early removal actions on 13 properties where surface residues exceeded applicable screening limits. Data generated by PNL during the various survey and sampling events was summarized in several investigation reports leading to the development of a City-wide removal action plan which will be implemented in 2019. Because of our long history with the Site, PNL was selected as the Client Representative for the City-wide removal action, and will be working collaboratively with the clients, KDHE, consultants, remedial contractors, and the City of Cherryvale to implement the work.

Project Navigator, Ltd. contracted to manage O&M at Bailey Waste Disposal Superfund Site

PNL has been contracted to manage the O&M of the Site remedy which includes two 7-acre engineered caps containing stabilized waste. The caps contain passive gas vents and extensive riprap for erosion protection. PNL’s scope of work includes maintaining the vegetation on the caps and within the riprap areas, conducting Site inspections, completing an annual Site Inspection Report and ensuring the remedy continues to be protective of human health and the environment. Additionally, PNL has been contracted as the Project Coordinator and Construction Manager for procurement and construction of a new Site access bridge.

Cr(VI) Background Study Update for Hinkley Groundwater Remediation Project

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.
