PFAS MDL Settlements: Red Herrings For Downstream Companies

Leading up to the aqueous film-forming foam (AFFF) MDL litigation bellwether trial in June 2023, questions circulated regularly about the end game for the water utilities that had filed lawsuits alleging PFAS contamination to drinking water. With several hundred utilities with pending lawsuits seeking the costs for technology needed to filter PFAS from drinking water, monitoring wells, testing equipment, disposal costs, etc., and potentially thousands of other water utilities with similar potential lawsuits, the damages seemed astronomical. So, too, did the amount of time it would take to litigate each case to get the water utilities monetary relief. These two competing forces, plus the pressure of an actual trial date looming, led Dupont and 3M to announce PFAS MDL settlements in June 2023. At $1.185 billion by Dupont and between $10.3 billion and $12.5 billion by 3M, with the intention of both settlement funds to resolve all pending and potential water utility claims in the United States, it seemed to many that a resolution had been achieved that would address PFAS in drinking water systems without burdening utility customers or the utilities themselves.

The issue, though, is that over 9,000 water utilities were estimated to be in need of treatment technology to meet the EPA’s newly proposed drinking water standards. The American Water Works Association (AMWA) reminded everyone that their own estimates of the costs of compliance to the EPA’s level would cost utilities over $3.2 billion annually. Even buying into the old joke that lawyers are horrible at math, it does not take long for one to realize the significant gap in the proposed settlement amounts and AMWA’s estimates. Water utilities accepting money under the Dupont and 3M settlement funds are not all going to receive 100% of the necessary funding for remediation. How then will this deficit be resolved?

Water utilities will be reluctant to pass on all of the costs to customers, although pricing increases could provide a stopgap measure for water utilities on top of the MDL settlement funds. State or even federal funding may be available under grant, loan or other programs that can also assist. However, when the dust settles, it is likely that water utilities are going to look to a particular group of parties to pursue damages from – companies that discharged PFAS into waterways that fed into the water utility facilities. Lawsuits already abound nationally filed by private citizens against such companies for property damage, bodily injury and medical monitoring. Why then would water utilities finding themselves in need of significant money to properly treat drinking water not take similar legal action? Couple this with pressure water utilities are starting to receive in the form of finding themselves sued in class action lawsuits by private citizens, and the legal notion of contribution begins to ring very true for water utilities looking to minimize their own damages in such lawsuits and find sources of funding for remediation technology.

Companies that have historically discharged effluent into waterways that feed drinking water supplies must therefore keep all of the above in mind and not be lulled into a false sense of complacency that the Dupont and 3M settlements in the MDL are going to mean the end of PFAS drinking water litigation. I predict quite the opposite.

It is of the utmost importance that businesses along the whole commerce chain that have or believe that they might have used PFAS in certain processes take steps now to understand their PFAS risk. Public health and environmental groups urge legislators to regulate PFAS at an ever-increasing pace. Similarly, state level EPA enforcement action is increasing at a several-fold rate every year. Companies that did not manufacture PFAS, but merely utilized PFAS in their manufacturing processes, are becoming targets of costly enforcement actions at rates that continue to multiply year over year. Lawsuits are also filed monthly by citizens or municipalities against companies that are increasingly not PFAS chemical manufacturers. The only way to manage future risk is to fully understand what that risk picture looks like, and companies would be well-advised to invest in proper diligence for the PFAS risk question.

Canadian PFAS Drinking Water Standards Proposed

We have documented for several years now the U.S. EPA’s efforts to propose enforceable drinking water standards with respect to PFAS, and in September 2022, the World Health Organization (WHO) issues its own draft “PFOS and PFOS In Drinking-Water” Background Document.  Now, on the heels of these developments, Canadian PFAS drinking water standards were introduced, which add another regulatory layer to the globally evolving PFAS regulatory scheme. Notably, Canada takes a different approach than both the United States and the WHO in addressing PFAS drinking water issues, but the proposal will nonetheless have impacts on U.S. PFAS litigation if passed.

Canadian PFAS Drinking Water Standards

Canada’s draft proposal sets a limit of 30 ppt for any detected PFAS combined in a given drinking water source. This is in contrast to the WHO, which only addressed PFOA and PFOS in its draft recommendations for drinking water standards, and the EPA, which by all indications will only propose enforceable drinking water standards for a small subset of the over 12,000 PFAS that exist. The Canadian standards, though, do propose requiring that EPA Testing Methods 533 or 537.1 be used for detection, which only tests for 29 PFAS types. Nevertheless, the large group approach to PFAS drinking water standards is unique for the moment to Canada, although the WHO did include in its proposal a similar limited subset of PFAS for countries to consider when setting or proposing drinking water standards.

Comments to the Canadian draft document are being accepted through April 12, 2023.

EPA’s Drinking Water Actions

We previously detailed how, on June 15, 2022, the EPA issued Health Advisories (HAs) for five specific PFAS, PFOA (interim), PFOS (interim), PFBS (final) and GenX (final). While not enforceable levels for PFAS in drinking water, the EPA’s PFAS Health Advisories are nevertheless incredibly significant for a variety of reasons, including influence on future federal and state drinking water limits, as well as potential impacts on future PFAS litigation.

The levels set by the EPA’s PFAS Health Advisories were as follows:

PFOA .004 ppt
PFOS .02 ppt
GenX 10 ppt
PFBS 2,000 ppt

Since the HAs were published, the EPA has faced several lawsuits challenging the HAs. The lawsuits generally allege that the HAs should be struck down and are not valid, as they were created “arbitrarily and capriciously.”  In support, the moving parties say that the HAs were created in an improper manner because (1) they incorporated toxicity assumptions that deviate from the EPA’s own standard methods; and (2) EPA incorporated grossly incorrect and overstated exposure assumptions―in essence, EPA used the wrong chemical when making its exposure assumptions, thereby resulting in a significantly less tolerant health advisory for [PFAS] than is warranted by the data. In addition, the parties argue that the EPA failed to go through the necessary public comment period before issuing its final GenX HA, and that in creating the GenX HA, the EPA exceeded its authority under the Safe Drinking Water Act.

Canadian PFAS Impacts On EPA Efforts and Litigation

When the WHO PFAS report was released, we wrote that the report will have an impact on existing and future litigation that challenges EPA regulatory actions focused on PFAS. Our reasoning for the prediction was that the standards proposed by the WHO were significantly higher than the EPA’s Health Advisories (which may foreshadow where the EPA’s enforceable drinking water limits will be set) even though the WHO had available to it much of the same scientific literature as the EPA. The Canadian PFAS drinking water proposal of 30 ppt is also higher than the EPA’s Health Advisories and what many predict will be the EPA’s proposed enforceable drinking water limit.  Future legal arguments challenging the EPA will likely say that the EPA is acting by ignoring the science and putting politics over the merits of scientific endeavor.

Nevertheless, whether the arguments challenging the EPA are found to be meritorious in litigation or not, the Canadian report will certainly provide ammunition to parties looking to challenge EPA action.

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 Roadmap 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.

Federal PFAS Drinking Water Standards: 2023 Is the Year

On Friday, October 7, 2022, the EPA formally sent its proposed federal PFAS drinking water standards to the White House Office of Management and Budget (OMB) for consideration and approval or rejection. The proposed rule cleared OMB review on November 30, 2022; however, the EPA has not yet released the proposed rule. While the details of the rule under consideration are not yet known, what is evident from the title of the document logged on the OMB website is that the drinking water standards will address PFOA and PFOS. At least from the document title, it does not appear that any other PFAS will be subject to Safe Drinking Water Act (SDWA) regulation at the moment.

The delay in releasing the proposed drinking water standards for over a month now, though, could suggest that the proposed rule may seek to regulate more than just PFOA and PFOS, and the EPA may be looking to shore up language and support language in the proposed rule for such a proposal in light of comments from the OMB. Similarly, many wonder whether the EPA proposed a limit so low that the OMB had concerns as to whether the limits were detectable. With the EPA keeping its proposed language a closely guarded secret for the time being, much of the discussions rest on speculation. What we do know is that he EPA is statutorily required to put forth a proposed standard before the first half of 2023, and it has publicly pledged repeatedly to act more quickly than that statutory requirements.

Thus, 2023 will see federal PFAS drinking water standards for at least two PFAS from the EPA and we predict that it is only a matter of days before the country sees the EPA’s proposal, which will kick off what promises to be an extremely contentious public comment period.

Now more than ever, the EPA is clearly on a path to regulate PFAS contamination in the country’s water, land and air. 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 Roadmap from 2021 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.

Draft EPA Study Finds Fracking Has Not Led to Widespread Drinking Water Contamination

The EPA released a draft of its study, U.S. EPA Assessment of the Potential Impacts of Hydraulic Fracturing for Oil and Gas on Drinking Water Resources (External Review Draft), EPA, Washington, DC, EPA/600/R-15/047, 2015, assessing the impact of hydraulic fracturing (fracking) on drinking water in early June (the draft Assessment). According to the EPA’s press release, the study finds that “hydraulic fracturing activities have not led to widespread, systemic impacts to drinking water resources,” but “identifies important vulnerabilities.” Fracking opponents, however, argue that the study vindicates their position.

The draft Assessment evaluated the potential impact of fracking at each stage of the Hydraulic Fracturing Water Cycle: water acquisition, chemical mixing, well injection, flowback, and wastewater treatment and waste disposal. The study’s objective was to “assess the potential impacts of hydraulic fracturing on drinking water resources, if any, and to identify the driving factors that may affect the severity and frequency of such impacts.” The draft Assessment “provides a review and synthesis of available scientific literature and data to assess the potential for hydraulic fracturing for oil and gas to impact the quality or quantity of drinking water resources, and identifies factors affecting the frequency or severity of any potential impacts.”

According to Dr. Thomas A. Burke, EPA’s Science Advisor and Deputy Assistant Administrator of EPA’s Office of Research and Development, the draft Assessment “is the most complete compilation of scientific data to date, including over 950 sources of information, published papers, numerous technical reports, information from stakeholders and peer-reviewed EPA scientific reports.”

[H]ydraulic fracturing activities have not led to widespread, systemic impacts to drinking water resources . . .

Supporters of fracking, such as American Petroleum Institute Upstream Group Director Erik Milito,say that the evidence gathered by EPA confirms that “[h]ydraulic fracturing is being done safely under the strong environmental stewardship of state regulators and industry best practices.” Meanwhile, opponents note that the EPA’s review found specific instances where well integrity and wastewater management related to hydraulic fracturing activities impacted drinking water resources. “The EPA’s water quality study confirms what millions of Americans already know – that dirty oil and gas fracking contaminates drinking water,” said Sierra Club Executive Director Michael Brune.

Numerous peer-reviewed EPA scientific reports were also released on the same day as the draft Assessment. Those reports were a part of EPA’s overall hydraulic fracturing drinking water study and contributed to the findings outlined in the draft assessment. More than 20 peer-reviewed articles or reports were published as part of this EPA’s draft Assessment.

The draft Assessment will be finalized after review by the Science Advisory Board (SAB) and public review and comment. The Federal Register Notice with information on the SAB review and how to comment on the draft assessment can be found here.
