PFAS regulation is one of the hot environmental topics and a key issue to watch during this next year. In this series of posts, V&E will address the increasing regulatory attention concerning a group of chemicals known as PFAS and the potential impacts this may have on affected industries.
Often referred to as “forever chemicals,” per- and polyfluoroalkyl substances (“PFAS”) are synthetic chemicals that have been widely used across the United States for several decades. Major environmental regulations and guidance aimed at addressing the potential adverse health effects of PFAS have been on the proverbial “horizon” for years and, in 2019 and 2020, the EPA ramped up regulatory activity. Although much of this activity is significant, the EPA has thus far avoided the action that would have the most wide-spread implications; namely, actually including some PFAS chemicals on the list of “hazardous substances” regulated under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and the Resource Conversation and Recovery Act (“RCRA”). EPA has, however, taken initial steps that could result in such regulation.
In this post, we’ll address the recent PFAS regulations and guidance and look ahead to what may change in 2021. Given the numerous industries that the EPA has indicated could be impacted by its actions last year — petroleum refineries and terminals, paper and textile mills, a number of industrial manufacturers (including for polymers, cleaning products, and paints), aviation operations, wastewater treatment plants, and landfills — it is important to understand what the EPA has already done, while also looking ahead to potential changes.
Regulations focused on PFAS have been added relatively steadily over the past twenty years or so with Significant New Use Rules published in March 2002, December 2002, October 2007, and October 2013.1 Additionally, in 2006 the EPA introduced the PFOA Stewardship Program with aims for participating companies “to commit to reducing PFOA from facility emissions and product content by 95% no later than 2010, [from a year 2000 baseline] and to work toward eliminating PFOA from emissions and product content no later than 2015.” However, 2019-2020 proved far busier still for PFAS regulations and guidance:
[I]n light of EPA’s success and experience in addressing PFAS in drinking water at levels above EPA’s current health advisory, EPA is reconsidering whether it should take any additional regulatory steps such as proposing to designate PFOA and PFOS as hazardous substances and, if so, what additional or alternate regulatory steps or authorities would be best suited and could be most appropriately tailored to address PFAS contamination in the environment. This notice seeks comment on the potential need for other regulatory steps and the benefits and the costs associated with such steps.5
During his election campaign, President Biden pledged to address PFAS in a number of ways and it is likely that 2021 will continue to see regulatory activity. Even without the change in administration, PFAS is an issue of widespread public concern, crossing the aisle and bipartisan support for action has grown in recent years. As we discussed previously, President Biden’s pick to lead the EPA — Michael Regan — has a reputation for his knowledge and experience on PFAS, and we expect him to play an active role as the federal government decides how to address these forever chemicals. It is also clear that the efforts to address PFAS will be shared with other Biden administration leaders. For example, PFAS and its regulation could have major implications for the Department of Defense, which has historically conducted training activities with firefighting foams containing PFAS. During his confirmation process, members of the Senate Armed Services Committee questioned Lloyd Austin, President Biden’s confirmed Secretary of Defense, on improvements to life on and near to military bases, including PFAS contamination cleanup. Austin confirmed that he would make PFAS remediation a priority and ensure that concrete steps would be taken to “finally do right by these communities.”
In addition, calls have already been made for the Biden administration to address the previous administration’s proposals. For example, because the EPA’s advance notice of proposed rulemaking seeking comment on whether the PFAS compounds PFOA and PFOS should be regulated under CERCLA and RCRA (see above) has not yet been published in the Federal Register, and will not be for some time yet, suggestions have been made to withdraw that notice and immediately restore the EPA’s original internal draft proposal which proposed to list the PFAS chemicals as “hazardous substances” under CERCLA.
Between the campaign promises, newly Democratic Congress, the prior experience of those likely to lead key federal agencies and overall public concern across bipartisan lines, we expect the coming year to exhibit continued action to address PFAS chemicals, either through new or existing environmental laws.
There will be continued focus on regulating PFAS under environmental laws in the new administration. One place to pay particular attention to is what the EPA decides to do regarding whether to list some PFAS chemicals as “hazardous substances” under CERCLA and RCRA. The EPA’s recent public notice on this issue indicates that there are multiple industries potentially affected if EPA proposes and finalizes a rule to designate PFOA and PFOS, including their salts and structural isomers, as CERCLA hazardous substances: PFOA and PFOS manufacturers and processors, manufacturers of products containing PFOA and PFOS, downstream product manufacturers and users of PFOA and PFOS products, waste management and wastewater facilities and anybody currently conducting a CERCLA clean-up where PFOA and PFOS may be found. In addition, public water systems will want to keep an eye on potential regulation of PFAS chemicals under the SDWA.
