U.S. EPA Finalizes Designation of Two PFAS Chemicals as Hazardous Substances Under CERCLA

On April 19, the U.S. Environmental Protection Agency (EPA) released its long-awaited final rule designating perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers, as “hazardous substances” under Section 102(a) of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA” or “Superfund”) (the “Final Rule”). The designation, which takes effect 60 days after the final rule is published in the Federal Register, will provide expanded investigation and remediation authority to EPA, will provide a powerful tool for private actions under CERCLA, and will trigger additional release reporting requirements. It will also expand enforcement authority in states that regulate CERCLA-designated hazardous substances.

Hazardous Substance Designation of PFOA and PFOS Has Broad Implications for Cleanups and CERCLA Liability

PFOA and PFOS are two specific chemical compounds within a broad group of thousands of manmade chemicals known as per- and polyfluoroalkyl substances (PFAS). EPA focused its regulatory efforts on these two PFAS; however, the vast majority of PFAS remain unregulated under CERCLA even after issuance of the Final Rule.

Designating PFOA and PFOS as hazardous substances triggers numerous requirements. The primary impact of the Final Rule is that it incorporates PFOS and PFOA into CERCLA’s strict, joint and several liability framework. This change grants EPA the power to investigate releases of PFOA and PFOS and compel potentially responsible parties (PRPs), including owners and operators of a property or facility, to remediate releases of PFOA and PFOS through the specific CERCLA enforcement provisions. PRPs also now have a clear private right of action under CERCLA to pursue cost recovery and contribution actions. Additionally, when the Final Rule becomes effective, facilities will be required to immediately report releases of PFOA and PFOS above their designated “reportable quantities,” (currently one pound within a 24-hour period), to the National Response Center and relevant state or tribal authorities.

Furthermore, many states include CERCLA hazardous substances under their cleanup statutes, meaning these states will now be able to require remediation of PFOA and PFOS under state law.

Listing PFOA and PFOS as “hazardous substances” under CERCLA does not make PFOA or PFOS contaminated waste a “hazardous waste” or a “hazardous constituent” under the Resource Conservation and Recovery Act. However, this designation does require the U.S. Department of Transportation to designate PFOA and PFOS as “hazardous materials” for purposes of transport under the Hazardous Materials Regulations.

While the PFOA and PFOS CERCLA Listing is Final, Questions Remain

As noted in our prior article on the proposed rule, EPA’s designation of PFOA and PFOS as “hazardous substances” leaves several questions unanswered.

  • How will EPA’s CERCLA enforcement discretion policy really play out in practice? 

    Concurrently with the publication of the Final Rule, EPA also released a PFAS Enforcement Discretion and Settlement Policy under CERCLA. This enforcement policy captures EPA’s current position that it does not intend to pursue PRPs under circumstances where “equitable factors” do not support doing so. Enumerated circumstances in the policy include so-called “passive receivers” of PFAS, including community water systems and publicly-owned treatment works, publicly-owned municipal solid waste landfills, publicly-owned airports and local fire departments, and farms where PFAS-containing biosolids are applied to the land. However, EPA’s enforcement policy—which is not binding upon the agency and is subject to change at any time—should be viewed with a healthy dose of skepticism among regulated industries, considering the sheer breadth of potential CERCLA liability for these substances, as well as continued Congressional proposals to codify exemptions for passive receivers within the CERCLA statute itself. Notably, the agency’s enforcement position does not in any way prevent private parties from initiating cost recovery or contribution actions under CERCLA.

  • How will regulated industries manage the costs of PFOA and PFOS cleanup?PFAS contamination can be wide-ranging due to several factors unique to the chemicals themselves. Further, unlike remediation technologies for other well-studied contaminants, existing remediation technologies for PFOA and PFOS are nascent at best and are expensive at a large scale. It is therefore often difficult to even estimate accurate cost ranges for PFOA and PFOS cleanups, but costs can easily run into the millions of dollars at complex sites. Although EPA has published interim guidance on PFOA and PFOS disposal methods, and the recently passed Infrastructure Investment and Jobs Act provides $3.5 billion over five years for Superfund cleanups, the methods and money may not go as far as planned if cleanup costs for PFOA and PFOS sites end up exponentially higher.
  • How will EPA handle potential PFOA and PFOS contamination at closed Superfund sites?In response to comments seeking clarification on whether designating PFOA and PFOS will lead to the reopening of closed Superfund sites, EPA stated that the final rule “has no impact” on EPA’s authority to list PFOA and PFOS sites as Superfund sites. EPA’s question-and-answers page—which we note is not a binding statement from the agency—also states that “[d]esignation will not change EPA’s process for listing and/or deleting [National Priorities List (NPL)] sites or evaluating remedies’ protectiveness through five-year reviews, and it will not require PFOA and PFOS sampling at NPL (final or deleted) sites.” While the final rule does not require PFOA and PFOS sampling at closed sites, it does not prevent EPA from ordering sampling at these sites. PRPs who may have long ago stopped budgeting for remedial costs at existing or legacy locations that were remediated years and even decades ago, may find that they are required to revisit these sites where PFOA and PFOS may be present.
  • What cleanup standards will govern PFOA and PFOS remediation?There is a current patchwork of state regulatory standards relating to PFAS, ranging from binding cleanup levels, advisory guidance, or no PFAS standards at all, which may lead to similarly patchwork cleanup standards depending on which standards are applied as an appropriate “applicable or relevant and appropriate requirement” (ARAR) at a specific site. In addition, on April 10, 2024, EPA issued a final rule setting Maximum Contaminant Levels (MCL) for PFOA and PFOS in drinking water at 4.0 parts per trillion (ppt), individually. While these drinking water standards are separate from EPA’s final rule listing PFOA and PFOS as “hazardous substances” under CERCLA, the “hazardous substances” rule notes that the MCL may be an appropriate ARAR for cleanup efforts under CERCLA.
  • What other PFAS will EPA next target under CERCLA?As noted above, PFOA and PFOS are two specific PFAS among thousands of others currently and historically used. Much of the science on the potential health effects of PFAS (both individual chemical compounds and as a class) continues to evolve. In the meantime, EPA has moved to regulate additional types of PFAS under other statutes. For example, as we noted in a previous client alert, EPA recently published a proposed rule listing seven other PFAS compounds as hazardous constituents under RCRA. Some or all of these PFAS may eventually be targets of future CERCLA rulemaking efforts.

Next Steps

The Final Rule will take effect 60 days after it is published in the Federal Register. Affected parties should consider their portfolio of planned, active, and in some cases, closed remediation sites for potential implications, and companies may consider reviewing and updating their hazardous substance reporting and transportation protocols to address PFOA and PFOS as applicable.

CERCLA PFAS Designation Major Step Forward

On January 10, 2022, the EPA submitted a plan for a PFAS Superfund designation to the White House Office of Management and Budget (OMB) when it indicated an intent to designate two legacy PFAS – PFOA and PFOS – as “hazardous substances” under the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA, also known as the Superfund law). The EPA previously stated its intent to make the proposed designation by March 2022 when it introduced its PFAS Roadmap in October 2021. Under the Roadmap, the EPA planned to issue its proposed CERCLA designation in the spring of 2022. On Friday, a CERCLA PFAS designation took a significant step forward when the OMB approved the EPA’s plan for PFOA and PFOS designation. This step opens the door for the EPA to put forth its proposed designation of PFOA and PFOS under CERCLA and engage in the required public comment period.

Any PFAS designation will have enormous financial impacts on companies with any sort of legacy or current PFOA and PFOS pollution concerns. Corporations, insurers, investment firms, and private equity alike must pay attention to this change in law when considering risk issues.

Opposition to CERCLA Designation

Since the EPA’s submission of its intent to designate PFOA and PFOS as hazardous substance to the OMB, the EPA has been met with industry pushback on the proposal. Three industries met with the OMB earlier in 2022 to explain the enormity of regulatory and cleanup costs that the industries would face with a CERCLA designation of PFOA and PFOS – water utilities, waste management companies, and the International Liquid Terminals Association. These industries in particular are concerned about bearing the burden of enormous cleanup costs for pollution that third parties are responsible for. Industries are urging the OMB and EPA to consider other ways to achieve regulatory and remediation goals aside from a CERCLA designation.

During an April 5, 2022 meeting of the Environmental Council of the States (ECOS), several states also expressed concerns regarding the impact that a CERCLA designation for PFAS types would have in their states and on their constituent companies. The state environmental leaders discussed with EPA representatives how the EPA would view companies in their states that fall into categories such as waste management and water utilities, who are already facing uphill battles in disposing of waste or sludge that contains PFAS.

Realizing that the EPA is likely set on its path to designate at least two PFAS as “hazardous substances”, though, industries are asking the EPA to consider PFAS CERCLA exemptions for certain industries, which would exempt certain industry types from liability under CERCLA. Industries are also pushing the EPA, OMB and the U.S. Chamber of Commerce to conduct a robust risk analysis to fully vet the impact that the designation will have on companies financially. The EPA is statutorily required to conduct a risk analysis as part of its CERCLA designation process, so it is likely that the EPA’s delay in issuing a proposed hazardous substance designation until it feels that adequate time has passed for its designation to survive the likely legal challenges that will likely follow the designation.

CERCLA PFAS Designation: Impact On Businesses

Once a substance is classified as a “hazardous substance” under CERCLA, the EPA can force parties that it deems to be polluters to either cleanup the polluted site or reimburse the EPA for the full remediation of the contaminated site. Without a PFAS Superfund designation, the EPA can merely attribute blame to parties that it feels contributed to the pollution, but it has no authority to force the parties to remediate or pay costs. The designation also triggers considerable reporting requirements for companies. Currently, those reporting requirements with respect to PFAS do not exist, but they would apply to industries well beyond just PFAS manufacturers.

The downstream effects of a PFOA and PFOS designation would be massive. Companies that utilized PFOA and PFOS in their industrial or manufacturing processes and sent the PFOA/PFOS waste to landfills or otherwise discharged the chemicals into the environment will be at immediate risk for enforcement action by the EPA given the EPA’s stated intent to hold all PFAS polluters of any kind accountable. Waste management companies should be especially concerned given the large swaths of land that are utilized for landfills and the likely PFAS pollution that can be found in most landfills due to the chemicals’ prevalence in consumer goods. These site owners may be the first targeted when the PFOA/PFOS designation is made, which will lead to lawsuits filed against any company that sent waste to the landfills for contribution to the cost of cleanup that the waste management company or its insured will bear.

Also of concern to companies are the re-opener possibilities that a CERCLA designation would result in. Sites that are or were previously designated as Superfund sites will be subject to additional review for PFOA/PFOS concerns. Sites found to have PFOA/PFOS pollution can be re-opened by the EPA for investigation and remediation cost attribution to parties that the EPA finds to be responsible parties for the pollution. Whether through direct enforcement action, re-opener remediation actions, or lawsuits for contribution, the costs for site cleanup could amount to tens of millions of dollars, of course depending on the scope of pollution.

Conclusion

Now more than ever, the EPA is clearly on a path to regulate PFAS contamination in the country’s water, land and air. The EPA has also for the first time publicly stated when they expect such regulations to be enacted. These regulations will require states to act, as well (and some states may still enact stronger regulations than the EPA). Both the federal and the state level regulations will impact businesses and industries of many kinds, even if their contribution to drinking water contamination issues may seem on the surface to be de minimus. In states that already have PFAS drinking water standards enacted, businesses and property owners have already seen local environmental agencies scrutinize possible sources of PFAS pollution much more closely than ever before, which has resulted in unexpected costs. Beyond drinking water, though, the EPA PFAS plan shows the EPA’s desire to take regulatory action well beyond just drinking water, and companies absolutely must begin preparing now for regulatory actions that will have significant financial impacts down the road.

EPA Sees New Challenges Ahead for Superfund

EPA released a four-year “strategic plan” on February 12 that continues to emphasize the EPA Superfund environmental clean-up program as one of Administrator Scott Pruitt’s top priorities.  While it has been clear since last summer’s Superfund Task Force report that the agency’s new leadership wants to accelerate Superfund site cleanups, the agency’s new strategic plan reveals for the first time that EPA also sees emerging challenges ahead for Superfund.

“A number of factors may delay cleanup timelines,” the agency wrote in its strategy document.  These factors include the “discovery of new pathways and emerging contaminants” such as vapor intrusion and per- and polyfluoroalkyl substances (PFAS), and new science such as “new toxicity information or a new analytical method.”

According to the strategic plan, the emergence of this kind of new information can reopen previously settled remedy determinations – and the Superfund sites that still remain on the National Priorities List (NPL) already tend to be the harder cases, with more difficult patterns of contamination and more complex remedies.  EPA flagged in particular its waste management and chemical facility risk programs, where “rapidly changing technology, emerging new waste streams, and aging infrastructure present challenges[.]”

It remains to be seen whether the agency’s cautions in the Superfund section of its strategy document represent a meaningful shift in the agency’s frequently-stated intention to reinvigorate the Superfund program.  Early in his tenure, Mr. Pruitt charged his Superfund Task Force with generating a series of recommendations centered around Mr. Pruitt’s goals for Superfund: faster cleanups, the encouragement of cleanup and remediation investments by PRPs and private investors, and a process centered on stakeholder engagement and community revitalization.  In December, in response to one of the Task Force’s recommendations, the agency released a list of 21 high-priority NPL sites that Mr. Pruitt targeted for “immediate and intense attention,” according to an EPA press release.  The cautionary notes in this week’s strategic plan are a subtle shift in tone for EPA.

At the same time, the document also sets forth a plan for improving the consistency and certainty of EPA’s enforcement activities in the regulated community.  It remains to be seen how EPA intends to achieve consistency while being responsive to state and tribal interests.

These goals, of course, will depend on the details of implementation, which are not set forth in the strategic plan.  And such details will depend on the agency’s budget, which remains in flux for 2019 and beyond.  For example, EPA’s proposed budget for fiscal year 2019 sought a roughly $327 million cut in the Superfund program, but the funds were added back into the budget proposal as part of last-minute budget agreement reached in Congress last week, securing the program’s funding in the short-term.   Last year, the administration proposed a 30% cut in the agency’s funding  but Congress balked and eventually approved a budget that cut roughly 1%.
