As the Biden-Harris administration draws to a close, EPA has issued its third annual report touting the progress made under the PFAS Strategic Roadmap.

In the report, EPA notes the major legal, technical, and policy developments it has enacted since the PFAS Strategic Roadmap was adopted in 2021. Those developments include the following:

  • Designation of PFOA and PFOS as CERCLA Hazardous Substances. This final rule will allow EPA and others to pursue potentially responsible parties under CERCLA for PFAS contamination. According to EPA, this designation will ensure that polluters, and not taxpayers, will pay for PFAS cleanups.
  • Creation of Drinking Water Standards for Certain PFAS. This final rule established enforceable drinking water standards for 5 individual PFAS and mixtures of any 2 or more of 4 individual PFAS. These drinking water standards are as low as 4 parts per trillion for PFOA and PFOS.
  • Chemical and Product Regulation. EPA has enacted or proposed a number of regulations under the Toxic Substances Control Act (TSCA) to eliminate and reduce PFAS in commerce. It also is requiring manufacturers and importers of PFAS (including PFAS-containing items) to report PFAS-related information to EPA by (in most cases) January 11, 2026.
  • Issuance of PFAS Enforcement Strategy. EPA issued a PFAS Enforcement Discretion and Settlement Policy Under CERCLA, detailing its priorities and plans when it comes to PFAS enforcement. In the policy, EPA makes it clear that it intends to pursue enforcement against manufacturing and industrial entities, and not public entities that operate water and wastewater systems, airports, or fire stations.
  • PFAS-Related Investments. The Biden-Harris administration committed to investing significant funds to address PFAS contamination, including $10 billion to assist communities and water systems impacted by PFAS and other emerging contaminants.
  • Advancing the Science on PFAS. EPA has engaged in a number of initiatives to gather more data about the presence of PFAS in the environment and in products, analyze appropriate test methods, and study potential human health risks associated with a variety of PFAS compounds.

EPA also announced future priorities, which include developing effluent limitations guidelines for the PFAS manufacturing sector. If adopted, these guidelines would restrict PFAS in discharges from potentially a number of industrial entities, including metal finishers and landfills. EPA also continues to invest in collecting data from a variety of sources, including wastewater treatment facilities, to further understand where PFAS are being found so it can develop effective ways to address them.

Of course, with the impending change in administrations could come a change in EPA’s priorities related to PFAS. The change could also impact initiatives and regulations that are already in place or in the works. We will continue to monitor PFAS developments as we head into 2025.

On July 30, 2024, the U.S. EPA Office of Inspector General issued a fraud alert to bring attention to an increasing number of companies reporting that they have received fraudulent EPA Notice of Violation letters demanding payment. Businesses have received these fraudulent letters through email and U.S. Postal Service mail. The letters allege that the target business violated an environmental regulation, such as the Clean Air Act or Clean Water Act. The contact information provided – invoice@epa.services – is not associated with the EPA. Official U.S. government organizations only use the “.gov” domain name.

If you have received a Notice of Violation and are concerned about its validity or have other questions or concerns, consider consulting experienced legal counsel. You can also contact the U.S. EPA’s enforcement office at OECA_Communications@epa.gov with any concerns regarding potentially fraudulent letters.

The U.S. EPA’s Office of Inspector General’s Hotline ((888) 546-8740 or OIG.Hotline@epa.gov) is always available if you believe you have been the victim of fraud or have knowledge of potential waste, fraud, or abuse involving EPA operations and programs.

On July 2, 2024, OSHA released the long-awaited Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings proposed rule. If finalized, the rule would require millions of employers to take steps to protect their workers from extreme heat. However, the proposed rule would not apply to “sedentary” or remote workers, emergency-response workers, or employees at indoor job sites where temperatures are kept below 80 degrees Fahrenheit.

Under the proposed rule, employers would be required to identify heat hazards, develop emergency response plans related to heat illness, and provide training to employees and supervisors on the signs and symptoms of such illnesses. Employers would also have to establish appropriate rest breaks, provide shade and water, and heat acclimatization for new employees and those employees that have been away from the worksite for more than 14 days.

The final regulation will almost certainly face lawsuits from a variety of entities. Several major industries and trade groups, including many in the construction and manufacturing space, had previously raised concerns about the implement ability of several concepts included in the proposed rule. Such legal challenges are likely to be boosted by the U.S. Supreme Court’s ruling last week eliminating the deference that courts owe to agency rulemaking.

However, before the proposed rule can become a final regulation, it must undergo a public notice and comment period. OSHA encourages the submission of written comments on the rule once it is published in the Federal Register. OSHA also has plans to hold a public hearing after the close of the written comment period. More information will be available on how and where to submit comments when the proposed rule is officially published in the Federal Register.

While we wait for the rule to become final, OSHA has made clear that it will continue to hold employers accountable for violations of the General Duty Clause and other regulations implicated by heat-related injuries and illnesses. This includes the continuation of heat-related inspections under OSHA’s National Emphasis Program – Outdoor and Indoor Heat-Related Hazards, which began in 2022.

Employers of all sizes and industries would be impacted from a final regulation on extreme heat. While the proposed rule is not yet binding on employers, it can be helpful to review the rule and evaluate whether your workplace is safe, healthy, and free from recognized hazards that could cause death or serious physical harm – such as exposure to extreme or excessive heat.

Below is an excerpt of a legal update co-authored with Real Estate + Development Group lawyer Eden Yerby.

In companion rulings favoring offshore wind developers and federal agencies, the First Circuit Court of Appeals recently affirmed rulings issued by the District Court (D. Mass.) and dismissed challenges brought by two Vineyard Wind opponents concerning the project’s potential impact on the endangered North Atlantic right whale.[1] In both cases, a panel of the same three judges addressed challenges to the administrative procedures followed by the National Marine Fisheries Service (NMFS) and the Bureau of Ocean Energy Management (BOEM) in issuing a biological opinion and an Incidental Harassment Authorization (IHA) for the project that would directly impact the right whale. In two decisions authored by Judge Kayatta analyzing aspects of the federal permit approval process, the Court ruled that the agencies properly evaluated potential impacts to the right whale and did not violate the authorizing statutes or otherwise act arbitrarily or capriciously. Read the full legal update.

EPA recently issued its long-awaited rule designating perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Along with the rule, EPA issued PFAS Enforcement Discretion and Settlement Policy Under CERCLA. This policy document provides the regulated community with some insight as to how EPA may roll out this rule in practice.

According to the policy document, EPA intends to focus its PFOA/PFOS CERCLA enforcement efforts on “responsible entities who significantly contributed to the release of PFAS into the environment, including parties that manufactured PFAS or used PFAS in the manufacturing process, federal facilities, and other industrial parties.” EPA does not intend to use its CERCLA authority to pursue certain public and other entities, such as:

  • Community water systems
  • Publicly owned treatment works (POTWs)
  • Publicly owned/operated municipal solid waste landfills
  • Publicly owned airports
  • Local fire departments

Based upon how PFAS are being investigated and discovered in the environment, the above entities are often on the front lines of identifying PFAS in the environment. They are also providing important public services. Because of this, EPA intends to focus its enforcement efforts elsewhere.

In considering whether to pursue other parties under CERCLA, EPA will consider a number of factors:

  • Does the entity manufacture PFAS or used PFAS as part of an industrial process?
  • Is the entity is actively involved in the use, storage, treatment, transport, or disposal of PFAS?
  • Does the entity perform a public service role?
  • Is the entity a state, local, or tribal government?

Based on the above factors, it seems clear that EPA intends to focus its PFAS CERCLA enforcement efforts on the manufacturing and industrial sectors. That enforcement activity could very well arise out of contamination discovered in water systems, POTWs, landfills, etc., but it appears EPA will focus on the manufacturing and industrial entities that may have contributed PFAS to the environment.

EPA will also seek to protect the public entities listed above in pursuing CERCLA settlements. For example, when EPA enters into a settlement with a PFAS manufacturer, it may look to secure a waiver of rights to prevent that manufacturer from seeking contribution from certain non-settling parties. EPA may also enter into favorable settlements with the public entities listed above to shield them from lawsuits from other potentially responsible parties.

EPA makes it clear that this enforcement policy applies to CERCLA only. EPA further reserves the right to change this policy as the scientific and legal landscapes evolve. That said, for now, it appears that the manufacturing and industrial communities may find themselves in the crosshairs of CERCLA enforcement.

On May 10, 2024, extensive revisions recently adopted by the Environmental Protection Agency (EPA) to the Risk Management Program (RMP) regulations (40 CFR Part 68) will take effect. The revisions, dubbed by EPA as the “Safer Communities by Chemical Accident Prevention Rule,” reinstate certain Obama-era provisions previously rolled back under the Trump administration. However, the revisions also enlarge some of these provisions and add significant new requirements, including some that reflect the current administration’s focus on climate change and environmental justice.

The revisions require owners and operators of subject facilities to achieve compliance with most of the substantive requirements within three years (i.e., by May 10, 2027). RMP plans must be updated to reflect new applicable requirements and resubmitted to EPA within four years (i.e., by May 10, 2028). For certain other requirements (regarding emergency response field exercises), the compliance deadline is potentially shorter or longer than these three- and four-year periods, depending on the date of the facility’s most recent field exercise.

Once the rule takes effect, court challenges by both business interests and environmental groups are expected. However, given the unknown outcome of such challenges and the breadth and potential costs of the new requirements, potentially impacted facilities should begin assessing the applicability of the revisions now.

Background

The RMP regulations implement Section 112(r) of the 1990 Clean Air Act Amendments (42 U.S.C. 7412(r)), which direct EPA to develop regulations to improve the prevention of chemical accidents at stationary facilities or activities (for brevity, referred to here simply as “facilities”) that use or store “regulated substances” that EPA has identified as presenting the greatest risk of harm from accidental releases. In particular, the owner and operator of a facility with one or more “processes” that manufactures, uses, stores, or handles such a regulated substance in excess of substance-specific threshold quantities must develop and implement a risk management program for all such processes, and document that program in a risk management plan submitted to EPA.

RMP requirements are generally similar to, and in some respects will overlap with, requirements under the Process Safety Management (PSM) program administered by the Occupational Safety and Health Administration (OSHA). However, while OSHA’s PSM regulations focus on workplace safety, the RMP regulations focus primarily on minimizing the public impacts of accidental releases through prevention and emergency response.

Earlier this year, the Connecticut Department of Energy and Environmental Protection (DEEP) released a “Connecticut Environmental Justice Public Participation Guidance Document” (‘the Guidance”) concerning the 2023 amendments to Connecticut’s environmental justice (EJ) statute regarding permitting or other approvals for certain facilities. Although helpful in indicating DEEP’s interpretation of the amended statute (which is not a model of legislative clarity), the Guidance leaves open many questions and raises some new ones. Beyond the Guidance, however, DEEP recently announced a general schedule for developing regulations to implement the most significant part of the amendments: cumulative impact assessments.

Background

Since its adoption in 2009, Connecticut’s EJ statute (Conn. Gen. Stat. § 22a-20a) has applied to “affecting facilities” that are located in or proposed to be located in an “environmental justice community” (both terms defined by the statute) and that apply to DEEP for a new or expanded permit, or to the Connecticut Siting Council for a Certificate of Environmental Compatibility and Public Need. For such facilities, the statute has required applicants to develop and implement a “meaningful public participation plan” and potentially enter into a “community environmental benefit agreement” (CEBA) between the applicant and the host municipality to mitigate potential environmental impacts of the affecting facility.

The 2023 amendments (Public Act 23-202) became effective on October 1, 2023. The amendments primarily do two things: (1) further enlarge applicant obligations concerning public participation, and most significantly, (2) make an assessment of the cumulative impact of “environmental and public health stressors” a new element in reviewing – and potentially denying – “affecting facility” applications. However, the amendments state that the cumulative impact assessment features shall not take effect until DEEP has adopted implementing regulations. The statute also requires DEEP to consult with stakeholders in this effort.

Public Participation Guidance

The recent Guidance addresses only the enhanced public participation features of the 2023 amendments and expressly does not address the cumulative impact assessments. It simply states that the development of the cumulative impact regulations will “take time.” The 2023 amendments also call for DEEP to adopt implementing regulations for the enhanced public participation features. However, the Guidance does not address such regulations or provide a timeline for their implementation.

The Guidance does highlight new requirements regarding public participation and presents DEEP’s integrated understanding of such requirements.  Much of this understanding is straightforward. For example, “affecting facility” applicants must now not only prepare and receive DEEP approval for a “meaningful public participation plan” before filing the application in question but must also prepare and receive DEEP approval for a report regarding the results of such public outreach in order for the application to be deemed sufficient. 

Beyond that, Goal 8 of DEEP’s recently announced “20BY26” plan includes several steps that DEEP plans to take regarding the enhanced public participation under the 2023 amendments, including:

  • Making all EJ public participation plans and CEBAs publicly available, including those that DEEP has previously received.
  • “Produc[ing] other tools … [to] facilitate efficiency and engagement,” such as more guidance to clarify how DEEP permitting and other programs interact with EJ communities, and to highlight opportunities for public participation in DEEP programs. 

While much of the Guidance is a relatively straightforward reflection of the 2023 amendments, at times the Guidance appears to provide DEEP’s interpretation of certain provisions in the amendments. Certain statements also may be susceptible to misinterpretation.  For example, in discussing applicability of the amended statute where an existing “affected facility” adds a new emissions unit or modifies an existing emissions unit, the Guidance references certain emissions rates (15 tons per year (TPY) for any individual air pollutant, and 10 TPY and 25 TPY for individual and aggregate hazardous air pollutants, respectively). DEEP has informally indicated that these figures are intended to mirror the applicability thresholds in the state’s air permitting regulations (RCSA 22a-174-3a(a)(1)).  This suggests that DEEP does not see the amended EJ statute as triggered by changes at an existing affected facility with relatively limited impact on air emissions. 

However, while the Guidance appears to say that these emission rates refer to actual emissions or increased actual emissions, in the air permitting regulations these figures refer exclusively to “potential emissions.”  This is a very conservative metric incorporating various worst-case and often very unrealistic assumptions, with the result that it is much easier to exceed a 15 TPY “potential emissions” threshold.  It would seem unlikely that the Guidance does not likewise intend to refer to “potential emissions.” The Guidance may also be susceptible to misinterpretation regarding modifications to existing affected facilities.  The Guidance appropriately notes that the EJ statute exempts “minor modifications,” but elsewhere states without qualification that the statute applies to an alteration of a facility that “may result in the discharge of any new water, substance or material.” (Emphasis added).  These examples underline that (as it itself notes) the Guidance is not a substitute for the statute itself.

Lastly, the Guidance does not address what DEEP envisions as a “reasonable fee” that the statute authorizes DEEP to charge “affecting facility” applicants to cover the cost of implementing the amended program.

Ultimately, while the Guidance is useful to some degree, the full impact of Public Act 23-202 will not be known until DEEP develops implementing regulations for the enhanced public participation requirements and particularly for cumulative impact assessments. 

Development of Cumulative Impact Regulations

In early March, DEEP announced an overall scheme and schedule for adopting cumulative impact regulations as Goal 7 in DEEP’s “20BY26” plan:

  • Hold “listening sessions” in EJ communities and with regulated parties (throughout 2024).
  • Release a Request for Proposals to develop “the ‘cumulative impacts tool’ that ultimately will give businesses the information that they can rely on to design, from the start, successful permit applications” (early 2024).
  • Propose “a strong but flexible set of rules” for public comment (late 2025). 

Interested parties would be well-advised to watch for opportunities for stakeholder involvement in these efforts as DEEP continues to implement the 2023 amendments. Those who are particularly interested can also sign up to receive DEEP’s Equity and Environmental Justice Newsletter, which includes timely updates on upcoming opportunities and events from DEEP’s Office of Equity and Environmental Justice.

The EPA Office of Inspector General’s (OIG) February 15, 2024, report on EPA’s practices in collecting, retaining, and producing criminal discovery materials in environmental cases found that EPA’s special agents largely adhered to requirements embedded in the due process clauses of the U.S. Constitution, the Brady doctrine, the Jencks Act, and the Federal Rules of Criminal Procedure. While the OIG identified some instances where agents deviated from procedures established by the Office of Criminal Enforcement, Forensics and Training (OCEFT) that could impact discovery during criminal proceedings, such as the use of a personal camera during an investigation, they did not amount to violations of applicable discovery requirements. Based on OIG’s evaluation, OCEFT was advised to review its policies and procedures to determine whether they required updating or whether the establishment of best practices was necessary. Alternatively, OIG recommended periodic training of EPA inspectors and investigators who may support the Government’s prosecution team.

Within EPA, OCEFT sits within the Office of Enforcement and Compliance Assurance (OECA), and both investigate violations of environmental laws and provide technical and forensic services for broader civil and criminal investigations. OCEFT is divided into three divisions: (i) the Criminal Investigation Division, (ii) the Legal Counsel Division, and (iii) the National Enforcement Investigations Center. In a federal investigation of potential environmental crimes, the EPA is considered part of the Government’s prosecution team and is primarily responsible for the investigation component of the process. OCEFT special agents work with the EPA and attorneys at the DOJ and in U.S. Attorney’s Offices. Individual agents are required to provide prosecutors with all potentially discoverable information for prosecutors to evaluate their discovery obligations. While special agents do not make those disclosure determinations, successful prosecutions require that all evidence has been collected in accordance with applicable constitutional and procedural requirements.

OIG’s assessment of OCEFT procedures focused on their application in individual cases to ensure that the Government met its discovery obligations when prosecuting environmental crimes. OIG found no instance where OCEFT agents did not adhere to criminal discovery requirements. It did note, however, circumstances in which agents did not fully apprehend investigative policies and procedures and would benefit from additional training.

The OIG report provides a good overview of EPA’s criminal enforcement procedures and the federal criminal process, generally, as it applies to environmental prosecutions. With OECA head David Uhlmann’s recent Senate confirmation, over two years following his nomination, the EPA now has all of its resources in place to address the agency’s high-priority concerns, including PFAS contamination.

On February 7, 2024, the U.S. Environmental Protection Agency (EPA) released its Final Rule lowering the primary annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM 2.5) from the current level of 12 micrograms per cubic meter (μg/m3) to 9 μg/m3.  Once published, the Final Rule is certain to be challenged in court. With that caveat, we summarize below the planned implementation and potential impacts of the new standard on sources of PM 2.5 or PM 2.5 precursor emissions. For more background, see our prior post about EPA’s 2023 proposal to lower the NAAQS and sources of PM 2.5.

Implementation

The Final Rule will take effect 60 days after notice of the Final Rule is published in the Federal Register. As of the date of this post, publication has not yet occurred.

To implement the new PM 2.5 NAAQS, the first step is for each state to develop recommended designations of areas in the state as attainment or nonattainment with respect to the new standard. According to the anticipated timeline in a February 7, 2024 memo from EPA Air chief Joseph Goffman, states would have until February 7, 2025 to submit these recommended designations to EPA. Following EPA review, public comment, and any necessary revisions, designations would be finalized in February 2026. The memo also notes that based on certain Clean Air Act provisions, EPA will initially classify all PM 2.5 nonattainment areas as “Moderate.” Thereafter, any such areas must achieve attainment by the end of the sixth calendar year after the effective date of the designation. EPA expects that 2032 is likely the earliest possible attainment deadline.

Based on 2016-2020 air quality data, and incorporating expected emission reductions from various programs (existing and planned) across the country, EPA projects that more than 99% of counties will attain the tightened annual PM 2.5 standard by 2032. As shown below, the most impacted state per EPA’s 2032 nonattainment projections is California, particularly the Central Valley and southern California. Remaining projected nonattainment areas are highly scattered across the lower 48 states, and include several major urban areas.

Source:  https://www.epa.gov/system/files/documents/2024-02/2024-pm-naaqs-final-2032-projections-map.pdf

However, projections using more recent data – on which EPA has said it expects states to base their attainment designation recommendations – suggest that the 9.0 μg/m3 standard could present much more widespread challenges. According to a recent report by the U.S. Chamber of Commerce (Chamber), average annual PM 2.5 emissions increased significantly from 2019 to 2023 across most of the eastern United States, and most of the country saw significant increases in ambient concentrations of PM 2.5 (as much as 2 to 3 μg/m3) in 2023 due to widespread wildfires.

Using data from 2021-2023, the Chamber considered how counties across the contiguous United States might fare under a 9.0 μg/m3 standard. Counties shown in red on the map below are those which would not meet the new standard, and therefore are vulnerable to a nonattainment designation, even if projected to reach attainment by 2032.  Because of the wildfire-related PM 2.5 spike in many areas of the country in 2023, it is expected that many states will ask EPA to apply its “exceptional events” policy to reduce their attributed PM 2.5 levels and avoid nonattainment designations.

Counties shown in green on the map below are those projected by the Chamber to attain 9.0 μg/m3 with “headroom” to spare (≥3 μg/m3, even before from any downward adjustment under EPA’s “exceptional events” policy).

The remainder of the country, shown in light red, is projected by the Chamber to fall 1 to 3 μg/m3 below the new standard, and would presumably be designated as attainment.  But being designated attainment is one thing; maintaining attainment is another. Absent downward adjustment from EPA’s “exceptional events” policy, PSD permitting authorities will likely be more wary of permitting additional emissions of PM 2.5 or PM 2.5 precursors that consume a significant share of the headroom remaining under 9.0 μg/m3 and, in the aggregate, could lead to a violation of the new NAAQS.

Further Potential Impacts

In addition to the potential impacts discussed above, the new NAAQS, once effective, will have an immediate impact on certain pending permit applications for PM 2.5 or PM 2.5 precursors in areas currently designated as attainment under the 12 μg/m3 NAAQS and prior PM 2.5 NAAQS. In such areas, Prevention of Significant Deterioration (PSD) permitting for construction of a new major stationary source or a major modification of an existing stationary source (as defined in EPA and state PSD regulations) under those NAAQS will continue to apply. However, once the Final Rule takes effect, pending, as well as future, PSD permit applicants for a PM 2.5 or a PM 2.5 precursor source will need to incorporate the new standard into their air quality impact analyses. More specifically, applicants will need to demonstrate that their source will not cause or contribute to an exceedance of the 9 μg/m3 NAAQS, as well as the 12 μg/m3 NAAQS and prior standards.

In areas ultimately designated as nonattainment under the new NAAQS, the permitting impacts would be more severe. Under the Clean Air Act, construction of a new major stationary source of PM 2.5 or a PM 2.5 precursor or a major modification of an existing major stationary source would be subject to Nonattainment New Source Review permitting, which requires stringent emission controls and offsetting emission reductions elsewhere at the source or at other sources.  Existing major sources that do not undergo a major modification would be subject to Reasonably Available Control Measures, including Reasonably Available Control Technology (RACM/RACT). 

Other Features of the Final Rule

As in the proposed rule, the Final Rule retains all other existing particulate matter NAAQS (the primary 24-hour PM 2.5 standard and the identical secondary standard; the secondary annual PM 2.5 standard; and the primary 24-hour coarse particulate matter (PM 10) standard and its identical secondary standard). Although EPA solicited comments regarding reducing the 24-hour PM 2.5 primary and secondary standards from the current 35 μg/m3 to as low as 25 μg/m3, the agency determined that the existing standards already provide “appropriate supplemental protection against elevated peak concentrations of fine particles.” In justifying this decision, EPA emphasized its holistic evaluation of the public health protections offered by the full suite of PM standards.

The Final Rule also provides for adjustments to the nationwide PM 2.5 monitoring network, with  an environmental justice focus: when siting monitors, monitoring agencies must consider the proximity of sensitive communities to PM 2.5 emission sources of potential concern.

*          *          *          *          *

This summary highlights some of the many unknowns regarding the new NAAQS at this early stage.  Subject to the outcome of expected legal challenges to the standard, the next few years should clarify its impact on permitting and other regulation of PM 2.5 and PM 2.5 precursor sources.  

On February 8, 2024, the U.S. Environmental Protection Agency (EPA) published two proposed rules in the Federal Register that would expand the EPA’s authority to address certain per-and polyfluoroalkyl substances (PFAS) under the Resource Conservation and Recovery Act (RCRA). These rules would significantly increase the EPA’s and authorized state’s authority to address the release of some of the most common PFAS and require responsible parties to conduct assessments, investigations, and clean-ups.

The first proposed rule, Listing of Specific PFAS as Hazardous Constituents, seeks to add nine PFAS, their salts, and their structural isomers to RCRA’s list of hazardous constituents. It is important to note that this is not the same as a “hazardous waste” listing under RCRA, which would automatically designate substances as “hazardous substances” under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), also known as Superfund.

The nine PFAS listed in the proposed rule are:

  • perfluorooctanoic acid
  • perfluorooctanesulfonic acid
  • perfluorobutanesulfonic acid
  • hexafluoropropylene oxide-dimer acid
  • perfluorononanoic acid
  • perfluorohexanesulfonic acid
  • perfluorodecanoic acid
  • perfluorohexanoic acid
  • perfluorobutanoic acid

The stated purpose of this proposed rule is to bring PFAS into RCRA’s Corrective Action program, which requires that the owner or operator of a facility with a permit or interim permit for the treatment, storage, or disposal of hazardous waste initiate corrective action to protect human health and the environment for all releases of hazardous wastes or hazardous constituents. It also means that the EPA has found that these substances have been shown in scientific studies to have “toxic, carcinogenic, mutagenic or teratogenic effects on humans or other life forms.”

The second proposed rule, Definition of Hazardous Waste Applicable to Corrective Action for Releases from Solid Waste Management Units, seeks to amend the definition of “hazardous waste” and authorize the EPA to require corrective actions to address releases from RCRA-regulated solid waste management units (SWMU) of any substance that meets the statutory definition of hazardous waste — not only substances identified as hazardous waste or constituents in the RCRA regulations. This action is designed to enhance the EPA’s position that it has the authority to use the RCRA Corrective Action program at permitted facilities to address both listed hazardous waste and constituents – including the nine PFAS identified in the first proposed rule – but also other emerging contaminants, such as any of the thousands of other PFAS, if it can be shown that they meet the statutory definition of “hazardous waste.”

Taken together these proposed rules represent an important step forward in the EPA’s PFAS Strategic Roadmap by expanding the EPA’s authority to address releases of the nine listed PFAS (and potentially more) and set the stage for the EPA’s impending proposed rules to designate two PFAS – Perfluorooctanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS) – as hazardous substances under CERCLA and to establish a national primary drinking water standard for PFAS.

Comments on the listing of the nine PFAS are due April 8, while comments on the expansion of EPA’s RCRA authority are due on March 11.
