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.

EPA Designates Two PFAS as Hazardous Substances

On April 19, 2024, the U.S. Environmental Protection Agency (EPA) announced that it was designating two common per- and polyfluoroalkyl substances (PFAS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund. As expected, EPA is issuing a final rule to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances. The pre-publication version of the rule is available here.

Once the rule is effective, entities will be required to report releases of PFOA and PFOS into the environment that meet or exceed the reportable quantity. Reporting past releases is not required if the releases have ceased as of the effective date of the rule. EPA will have the authority to order potentially responsible parties to test, remediate, or pay for the cleanup of sites contaminated with PFOA or PFOS under CERCLA.

Massachusetts established reportable concentrations for six PFAS, including PFOA and PFOS, in 2019. The Massachusetts regulations also contain cleanup standards for PFAS contamination in soil and groundwater.

Under Maine law, these substances also are automatically deemed a Maine hazardous substance regulated under the Maine Uncontrolled Hazardous Substance Sites Law. Maine’s PFAS screening levels are available here.

Solid waste facility operators had expressed serious concerns about the prospect of PFOA and PFOS being listed as hazardous substances under CERCLA and have advocated for a narrow exemption. Landfills can be recipients of PFAS-containing waste without knowing it. Similarly, wastewater treatment plant operators feared liability and increased costs if the rule designating PFOA and PFOS as hazardous substances became final.

EPA’s announcement of the final rule came with a CERCLA enforcement discretion policy [PFAS Enforcement Discretion and Settlement Policy Under CERCLA] that makes clear that EPA will focus enforcement on parties that significantly contributed to the release of PFAS into the environment.

The policy states that the EPA does not intend to pursue certain publicly‑owned facilities such as solid waste landfills, wastewater treatment plants, airports, and local fire departments, as well as farms where biosolids are applied to the land. Firefighting foam (aqueous film-forming foam, or AFFF) is known to contain PFAS, and runoff from the use of AFFF has been known to migrate into soil and groundwater.

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.

PFAS Water Cleanup…Have You Bought Yourself a Multi-Million Dollar Superfund Issue?

The last two years have seen an incredible uptick in activity with respect to PFAS regulations, and media coverage of PFAS continues to fuel the fires from the public, non-government organizations and environmental groups for additional action to be taken. The EPA continues its process of determining Maximum Contaminant Levels for PFAS. The FDA is examining the ways that it might regulate PFAS levels in both food and food packaging. Meanwhile, states, bombarded with constituent outcries and under pressure to take action to fill the gap until the EPA and FDA finish their regulatory review processes, quickly enact drinking water limits for PFAS and ban PFAS-containing products, such as children’s toys and food packaging.

As states continue setting drinking water limits for PFAS and in preparation for the EPA’s final determination of a Maximum Contaminant Level for PFAS in drinking water, many water utilities are beginning to evaluate the steps needed to come into compliance with existing or anticipated water regulations. Comprehensive compliance programs are being created and costly well testing sites are being built to determine PFAS content at various points along the waterways for drinking water sources. At water treatment facilities, expensive water filtration systems are being installed to remove as many PFAS as possible from drinking water sources. With water utilities coming under fire in the litigation world for PFAS issues, these steps may curtail the short-term issues and costs associated with PFAS litigation.

However, the long-term impact of the remediation steps that water treatment facilities ae taking may only be pushing litigation costs further down the road, not eliminating them. In addition, little considered Superfund laws may be triggered through PFAS water filtration that could end up costing water treatment facilities tens or hundreds of millions of dollars in cleanup costs.

CERCLA and PFAS

Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), once a substance is designated as “hazardous” by the EPA, the Act gives the EPA considerable power to designate sites containing such substances as Superfund sites and force parties responsible for the pollution to pay for the cleanup of the site. Without a designation of a substance as “hazardous” (and therefore a site as a Superfund site), the EPA may either pay for the cleanup of the site itself or attempt to pursue, through time-consuming and costly litigation, the property owner for the costs of cleanup.

One of the most closely watched developments in the PFAS world is whether the EPA will make the determination that PFAS are “hazardous” under CERCLA. Although the EPA has promised its determination soon and various lawmakers are pressuring the EPA to make a determination in the near future, it is still uncertain as to when the EPA will issue its final regulations.

In the meantime, however, water utilities are under increasing pressure to filter out PFAS from drinking water. These PFAS are typically deposited in landfills. Out of sight, out of mind? Not exactly, when it comes to PFAS. As the quantity of PFAS accumulate in landfills, if the EPA makes a determination that PFAS are “hazardous” substances under CERCLA, the EPA could immediately designate landfills full of PFAS as Superfund sites and take action to pursue parties to pay for the cleanup. Water utilities could therefore be at significant risk of having to pay for Superfund site cleanup.

Further, in some instances, water utilities may have previously been involved with Superfund site cleanup for other reasons and believed the site issues to be fully remediated.  However, since PFAS have not yet been classified as “hazardous”, Superfund sites were never tested for PFAS. Should the EPA determined that PFAS are “hazardous” under CERCLA, the EPA will have the right to reopen previously closed Superfund sites for further testing and remediation specific to PFAS, even if parties deemed responsible for the pollution already paid millions of dollars to clean up the site for other contaminants.

Water utilities in particular must pay special attention to PFAS developments under CERCLA. Proactive planning is needed to determine alternate means of disposing of or eliminating PFAS from water sources. Failure to enact forward-thinking strategies may very well end up costing water utility companies tens of millions in unexpected and unwanted costs if they fail to do so.

PFAS Rolling into Regulation

Introduction

Per- and polyfluoroalkyl substances, abbreviated as PFAS, are a class of widely dispersed chemicals quickly gaining notoriety in the public health and environmental remediation space. In 2019, rapid developments toward regulation to govern the investigation and cleanup of PFAS contamination to protect human health are occurring in a wide variety of arenas, including federal regulation and congressional action as well as at the state level through both regulation and enacted legislation. This article examines the current state of regulatory developments for PFAS and projects where things are heading in the remainder of 2019, with particular focus on how those developments will incentivize and accelerate the pace of site cleanups and cost recovery, and pose significant challenges to existing sites where other contaminants are already being addressed.

What are PFAS?

PFAS are a class of more than 4,000 synthetic chemicals comprised of carbon-fluorine chains of varying lengths. PFAS have been in use since the late 1940s, due to their unique resistant physical and chemical properties. For example, PFAS have been used in non-stick applications such as cookware, paper packaging, and textiles, as well as in certain types of firefighting foam.[1] The two most widely studied PFAS are perfluorooctane sulfonate or PFOS and perfluorooctanoic acid or PFOA.

Over the past decade, understanding of PFAS and their potential toxicity to humans and the environment has increased. Of particular concern is their stability in the environment. The properties that made PFAS so desirable for commercial and industrial use keep these compounds from degrading in the environment and allow them to pose a long-term threat if not removed from the environment and/or from drinking water supplies. Common exposure to these compounds can come through their product use as well as drinking from contaminated water supplies impacted by their release. Also notable are the very low levels at which these compounds exhibit their toxicity, and the very stringent levels under consideration by the regulatory agencies for controlling these compounds. For example, EPA has set interim screening levels of 70 nanograms per liter (parts per trillion or ppt), and several states have proposed guidance levels of 15 ppt or less. For context, 15 ppt is equivalent to a few droplets in an Olympic-sized swimming pool.

Federal Regulatory Developments

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) authorizes cleanup at sites where hazardous substances have been released, and enables parties conducting cleanups to seek cost recovery from other potentially responsible parties. The ability to potentially recover costs under CERCLA can be an important driver in encouraging impacted parties to investigate and remediate contaminated sites. However, as an emerging contaminant class, PFAS are not currently regulated as hazardous substances under CERCLA.

In February 2019, EPA issued an Action Plan outlining its steps to address PFAS and protect public health.[2] Among its listed priority actions was to propose a national drinking water regulatory determination for the two most widely studied PFAS, PFOA and PFOS, by the end of 2019. This proposed determination would begin the process towards establishment of a maximum contaminant level, or MCL, for these compounds. Another priority action was to initiate the process to list PFOA and PFOS as CERCLA hazardous substances; in April of 2019 at a meeting of state regulators, EPA committed to proposing this hazardous substance designation by the end of 2019.[3] Such a designation will have a multitude of impacts, including 1) PFOA and/or PFOS-contaminated sites will be eligible for listing as Superfund sites; 2) Federal and State authorities will have mechanisms through which they can seek damages or cleanup costs from responsible parties; and 3) Superfund monies will be eligible for use in cleaning up sites contaminated with PFOA and/or PFOS.

This commitment to regulate PFOA and PFOS under CERCLA was reaffirmed in a keynote speech of EPA’s General Counsel on September 12th at the American Bar Association, Section Environment, Energy, and Resources Fall Conference in Boston, Massachusetts. In his speech, the Honorable Matthew Leopold indicated that EPA was actively looking at designating PFOA and PFOS as CERCLA hazardous substances by year’s end. This would represent one of the few times in which new contaminants such as these were regulated under CERCLA.

Concurrent with these EPA actions, congressional legislators have called for increased and expedited federal action to regulate PFOA and PFOS, and in some cases the entire PFAS class of 4000 plus chemicals. There have been several bills proposed in 2019 which would commit EPA to taking expedited action with regards to PFAS, including listing some or all PFAS as hazardous substances, and establishing federal MCLs.[4] Perhaps most notably are two bills regarding appropriations for the Fiscal Year 2020 National Defense Authorization Act. S.1790 (passed by the Senate on June 27, 2019) would require EPA to promulgate drinking water MCLs for PFOA and PFOS within two years of enactment, and H.R.2500 (passed by the House on July 12, 2019) would require EPA to designate all PFAS as hazardous substances within one year of enactment.

State officials have also actively petitioned for more expedited federal action on PFAS. On July 30, 2019, 22 state and territory attorneys general issued a letter to Congress requesting that certain PFAS be designated hazardous substances, in particular, PFOA, PFOS, and a PFOA-replacement chemical known as GenX. In their letter, the attorneys general specifically note that such a designation would promote cleanup efforts, including federal facilities formerly owned or operated by the US Department of Defense.[5]

Based on these developments from multiple agencies and levels of government, it appears likely that in the relatively short term PFOA and PFOS will be designated as hazardous substances under CERCLA. This in turn will open the door for CERCLA regulation of PFAS-contaminated sites. Once designated, the next question will be one of appropriate cleanup levels. Typically, EPA would take the lead with establishment of MCLs that can be used to develop risk-based cleanup levels, and from which states could either adopt or modify. However, the process for proposing and finalizing a federal MCL can take years. Thus, faced with increasing public pressure to respond to PFAS contamination, the states have stepped in to fill this gap.

State Regulatory Developments

In November 2018, New Jersey became the first state to issue an MCL for any individual PFAS, specifically for the chemical perfluorononanoic acid (PFNA).[6] For PFOA and PFOS, there are currently no state MCLs that have been finalized. However, many states have established PFOA and PFOS advisory or screening levels, and several states have begun the MCL rule-making process, with some anticipating finalization this year.

In 2019, three states have proposed MCLs of varying concentrations for PFOA and PFOS:

  • In April, New Jersey proposed an MCL of 14 ppt for PFOA and 13 ppt for PFOS; the public comment period has since closed, and the standard is in the process of finalization;[7]
  • In June, New Hampshire proposed an MCL of 12 ppt for PFOA and 15 ppt for PFOS (they also proposed MCLs for two other PFAS chemicals);[8] those MCLs were approved on July 18,[9] and will become effective on October 1; and
  • In July, New York proposed an MCL of 10 ppt for PFOA and PFOS making them the most protective standards in the nation; the proposal is currently out for public comment, which closes on September 24.[10]

In addition, several other states have provided commitments to establishing MCLs in the near future. These include Massachusetts with an MCL rule proposal anticipated by the end of 2019;[11] Michigan with an MCL rule proposal expected by October with finalization in 2020;[12] and Vermont with a commitment to establishing and adopting MCLs by February 1, 2020.[13] Other states are also moving forward with efforts to regulate PFAS. For example, in August 2019 California established notification levels for PFOS and PFOA in drinking water of 6.5 ppt and 5.1 ppt, respectively, that go into effect January 1, 2020. [14],[15]

Conclusion

With federal and state regulatory action underway, and mounting public pressure to expedite a response, it is clear that regulation of some PFAS under CERCLA is imminent. By the end of the year, it is likely that 1) EPA will have designated, or be close to designating, PFOA and PFOS as hazardous substances; and 2) several states will have finalized MCLs to regulate their remedial response. These two developments will open the door for parties to investigate, cleanup, and ultimately recover the costs associated with PFAS-contaminated sites. In addition, these developments will likely complicate existing sites in terms of both their required remedial response as well as their cost recovery strategy. New PFAS regulation at existing sites will unlock a myriad of cost implications not the least of which involve cost allocation among potentially responsible parties. In the face of these complications and uncertainties, what is clear is that PFAS regulation has rolled off the horizon and directly in front of those involved with protecting public health and the environment.

Three Strategies to Develop Renewable Energy Projects on Potentially Contaminated Lands

Developing renewable energy on contaminated lands has proven to be both effective and cost-effective for companies pursuing a new solar or wind energy project. The utility-scale solar farm constructed on the 120-acre Reilly Tar & Chemical Corporation Superfund site is a great example, and there are thousands more that are ripe for redevelopment.

Renewable energy continues to grow in volume and importance in the U.S. as corporations drive demand for sustainable energy, with 166 companies to date committing to go 100 percent renewable as part of a global initiative called RE100. At the same time, states and local governments are driving policy that prioritizes sustainable energy development. Two recent Illinois bills, the Path to 100 Act (HB 2966/SB1781) and Clean Energy Jobs Act (HB3624/SB2132), seek to incentivize the development of new renewable energy and move the state to 100 percent renewable energy by 2050. Other states, including California, New Jersey, New York, and Wisconsin, have called for or passed similar laws.

Using Superfund sites, brownfields, retired power plants, and landfills offers potential benefits to developers and community stakeholders:

  • Preserve Open Space: Large-scale renewable energy facilities – often called “utility scale” projects – can require a lot of land that may displace or impact agricultural lands, open space, or other “greenspace.” Developing renewable energy on potentially contaminated properties can help to preserve the “greenspace” while returning blighted lands to sustainable and productive use.

  • Lower Costs and Shorter Timeline: Developers can significantly lower costs and timelines because contaminated sites are usually already served by existing infrastructure, like substations, power lines, and roads, which would otherwise need to be constructed. Streamlined permitting and zoning can also reduce costs and timelines because potentially contaminated property is often already zoned for industrial or commercial use, which likely poses fewer obstacles to constructing renewable energy structures. Decreased land costs, programs for the procurement of renewable energy credits generated from developing renewable energy projects on brownfields or potentially contaminated properties, and federal and state brownfield tax incentives can drive costs down even further.

  • Greater Community Support: Communities may be quicker to get behind renewable energy projects that are sited on potentially contaminated lands because, rather than taking agricultural land out of production, the projects can clean up the otherwise abandoned sites, boost surrounding property values, increase tax revenues, and provide low-cost clean power.

Despite these benefits, developers often build renewable energy facilities on greenspaces rather than brownfields because of concerns related to potential liabilities or contamination. Below are three strategies that developers can use to move past those concerns and develop a successful renewable energy project on potentially contaminated lands.

  1. Screen Sites for Renewable Energy Potential

Screen potentially contaminated properties to see whether they’d be a good fit for your renewable energy project. For example, confirm that a property has enough usable space and is close enough to transmission or distribution lines to support development. Determine whether a site is free from land-use restrictions that would preclude the use of your chosen renewable energy. Ensure the community doesn’t already have a plan in mind to redevelop the property you’re assessing. And inspect the property for evidence of potential contamination, like soil surface staining or debris stockpiles. If a site has not yet been assessed, you will need to investigate the site to determine whether redevelopment is appropriate. To help, the EPA has published guidance to assist prospective developers in screening prospective sites for solar and wind projects on potentially contaminated lands.

  1. Coordinate the Cleanup and Renewable Energy Development

Developing renewable energy can occur at any stage of a property cleanup, from site inspection and preliminary assessment to post-construction completion. However, identifying and coming to a site at the beginning of or early on in the cleanup process has its advantages. It allows you to engage the community and other stakeholders, including potentially responsible parties, from the start of the redevelopment. It also allows you to coordinate and integrate the cleanup and renewable energy development decisions. For example, you can work with the governmental agency overseeing the site to fold renewable energy design requirements into the remedial design, rather than having to construct renewable energy structures on top of and around the completed remedy. Getting in early will ensure that the renewable energy project is compatible with the remedial design, institutional controls, monitoring activities, and engineering controls.

  1. Protect Yourself from Liability Exposure

Many prospective developers, purchasers, and lenders stay away from or tread cautiously around building on contaminated properties for fear of liability under federal or state cleanup laws. However, many state cleanup programs provide liability protections for new owners or lessees, like a developer, who are not responsible for prior contamination at a site. The federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) also generally limits EPA enforcement at certain qualifying brownfield sites, known as “eligible response sites”, where a party is conducting a response action in compliance with a state cleanup response program. Contact a lawyer and work with state government early on in the process to see what liability protections are available to you and how to qualify.

Other contaminated properties may be addressed under the CERCLA cleanup program. CERCLA has several self-implementing liability protections for developers and the like who acquire contaminated property but did not cause the contamination, including a protection for “bona fide prospective purchasers.” Ensure that you take the required steps to qualify for the BFPP protection, which will include, among other things, working with an environmental consultant to conduct “all appropriate inquiries” through a Phase I environmental site assessment. CERCLA can also offer liability protections for people who lease contaminated properties.

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%.

EPA Issues Changes to Due Diligence Requirements for All Appropriate Inquiries (AAI) Under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)

RCA Logo

2005 ASTM No Longer Accepted Effective Oct. 6, 2015

On October 6, 2014, EPA issued a final rule mandating the use of the 2013 standard, ASTM E1527-13, for conducting Phase I Environmental Site Assessments for satisfaction of All Appropriate Inquiries (“AAI”) under CERCLA. [Click here for a copy of EPA’s preamble to the final rule, published in the federal register today].

In December 2013, EPA adopted a new AAI rule allowing use of the updated 2013 standard and continuing to allow use of the 2005 standard, ASTM E1527-05. The reference to both standards was widely criticized as a source of confusion in due diligence requirements. Prospective owners/operators were strongly encouraged to use the 2013 standard; however, they had flexibility to decide whether to use the 2013 or 2005 standard for each particular site.

Today’s revised AAI rule removes the reference to the 2005 standard, thus allowing use of only the 2013 standard for entities performing AAI. The new rule does not modify the 2013 standard; it merely mandates the use of it for AAI.

Notably, the new rule will not become effective until October 6, 2015, giving prospective property owners/operators and consultants one year to complete site assessments that are currently being performed consistent with the 2005 standard. Though EPA’s expectation is that entities will no longer use the 2005 standard and transition to the 2013 standard, the EPA’s rule allows use of the 2005 standard for property acquired prior to the effective date of October 6, 2015.

The primary differences between the 2013 and 2005 standards are:

  1. The 2013 standard requires evaluation of the potential for the release of subsurface vapor contamination (vapor migration), and more clearly identifies vapor migration as a recognized environmental condition. The 2005 standard did not explicitly require an analysis of vapor migration
  2. The 2013 standard clarifies existing and adds new definitions, which as a result, revises the potential scope of assessment. For example, the term “Controlled Recognized Environmental Condition” was added to the standard to include past releases that have been addressed but allow contamination to remain in place.
  3. The 2013 standard requires a more extensive review of agency files and historical site documents.

Overall, the 2013 standard is considered more comprehensive and thorough based on today’s realities and is touted by EPA in its final rule preamble as “the consensus-based, good customary business standard.”

EPA Clarifies Standards for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Assessments

Covington BUrling Law Firm

In a move designed to provide greater certainty to those purchasing, selling, or evaluating industrial or commercial properties, the Environmental Protection Agency (EPA)recently proposed to remove any lingering effect of ASTM International’s E1527-05, a nine-year-old industry standard practice for evaluating potentially contaminated sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

As explained in detail in our February 24, 2014 E-Alert, “Amended All Appropriate Inquiries (AAI) Rule Offers New Due Diligence Standard, Focuses on Vapor Releases,” the EPA referenced and countenanced ASTM International’s updated framework, E1527-13, as an alternative due diligence standard to ASTM E1527-05.  Issued on June 16, 2014, the Proposed Rule would clarify Phase I Environmental Site Assessment (ESA) standards by replacing ASTM E1527-05 with ASTM E1527-13.  Yet these requirements still leave significant uncertainty in the absence of more detailed guidance about how to conduct vapor intrusion evaluations.

I.  Background

International standards organization ASTM International modeled E1527-05 on the EPA’s All Appropriate Inquiries (AAI) Rule in 2005.  The AAI Rule is a due diligence standard that allows buyers of potentially contaminated properties who conduct an investigation meeting the rule’s requirements to preserve certain defenses to federal cleanup liability under CERCLA when conducting Phase I ESAs.  See 40 C.F.R. § 312 (2013).  The ASTM E1527-05 framework was developed to provide guidance for such investigations, and instructed would-be purchasers to undertake all appropriate inquiries regarding the condition of a property before completing its sale.  Any buyer who conducted such inquiries in compliance with ASTM E1527-05 could then qualify for certain landowner liability protections under CERCLA, including the innocent landowner, bona fide prospective purchaser, and contiguous property owner defenses.

Last December, the EPA amended the AAI Rule to allow a purchaser to satisfy Phase I ESA requirements by following either ASTM E1527-05 or ASTM E1527-13.  See 78 Fed. Reg. 79319 (Dec. 30, 2013).  As explained in our February 24, 2014 E-Alert, the 2013 framework included new regulatory file review requirements, updated definitions of certain key terms, including “de minimis condition,” “release,” “Recognized Environmental Condition,” and “Historical Recognized Environmental Condition,” and expanded ASTM E1527-05’s definition of “migrate/migration” to include vapor migrations.

II.  Proposed Rule

The EPA amended the AAI Rule through direct final rulemaking, an approach whereby an agency publishes a rule and a notice of proposed rulemaking simultaneously because it expects that the rule will prove non-controversial.  But the move nonetheless introduced confusion because in endorsing both ASTM E1527-05 and ASTM E1527-13, it recognized two distinct standards.

Responding to that criticism, the EPA has now proposed to replace ASTM E1527-05 with ASTM E1527-13 for purposes of the AAI rule so as “to reduce any confusion associated with the regulatory reference to a historical standard” and “promote the use of the standard currently recognized by ASTM International as the consensus-based, good customary business standard.”  Amendment to Standards and Practices for All Appropriate Inquiries, 79 Fed. Reg. 34480 (proposed June 16, 2014) (to be codified at 40 C.F.R. 312), at 11.  Besides removing all references to ASTM E1527-05, the Proposed Rule would not alter the substance of the AAI Rule.

III.  Implications

ASTM E1527-13 incorporates new language about the need to evaluate soil vapor risk when conducting Phase I ESAs.  Soil vapor intrusion is of particular focus with respect to TCE and other volatile organic compounds, but can also involve other contaminants.  The EPA has suggested, however, that a vapor intrusion evaluation may already have been required under ASTM E1527-05.  In its preamble to the rule offering ASTM E1527-13 as a new due diligence standard, the agency stated that it “in its view, vapor migration has always been a relevant potential source of release or threatened release that, depending on site-specific conditions, may warrant identification when conducting all appropriate inquires.”  78 Fed. Reg. 79319 (Dec. 30, 2013).  It is unclear, however, whether the EPA intended this statement to reflect near contemporary Phase I ESAs (conducted after ASTM E1527-13 was developed) or instead intended to suggest that the obligation has always existed.  Consequently, there may be future disputes as to whether a Phase I ESA not describing an evaluation of soil vapor intrusion actually satisfied the AAI Rule.

ASTM E1527-13 leaves open a number of key questions about vapor intrusion evaluations.  Neither ASTM E1527-13 nor the AAI Rule describes, for example, what levels in soil gas or groundwater should lead to concern or what levels would require mitigation.  The EPA and various states are developing guidance in this area to further clarify acceptable levels, how evaluations are to be conducted, whether one can evaluate risk based upon groundwater conditions alone, whether an evaluation must consider multiple lines of evidence, what vapor levels would be deemed acceptable in a residential setting, and what actions are required to mitigate risk.[1]

IV.  Conclusion

Consultants have already been transitioning toward the ASTM E1527-13 standard.  Should the Proposed Rule be adopted, ASTM E1527-05 will still satisfy the AAI Rule for properties acquired between November 1, 2005 and the effective date of the new action.  The EPA also anticipates providing for a delayed effective date of one year following any final action, to give those still using the previous framework time to complete ongoing investigations and become familiar with the updated standard.

However, it is important to recognize the potential that the EPA may claim that a failure to evaluate soil vapor, where otherwise appropriate, is a requirement under ASTM E1527-05 and not only ASTM E1527-13.  It is therefore essential that potentially-affected individuals keep current on EPA developments with respect to the evaluation of soil vapor intrusion, and obtain sound and up to date advice from environmental professionals.

Supreme Court Decides CTS Corp. v. Waldburger Evaluating Whether CERCLA Precludes State-Law Statutes of Repose

SchiffHardin-logo_4c_LLP_www

On June 9, 2014, the Supreme Court decided CTS Corp. v. Waldburger, holding that a North Carolina statute of repose was not preempted by Section 9658 of theComprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

From 1959 until 1985, CTS Corporation manufactured electronics on a piece of property in North Carolina.  CTS sold the property in 1987.  Owners of both the former CTS property and adjacent property filed state-law nuisance claims in 2011, alleging that they had learned from the United States Environmental Protection Agency (USEPA) in 2009 that their groundwater was contaminated.  A district court relied on N. C. Gen. Stat. §1-52(16), a North Carolina statute which bars property damage claims made “more than 10 years from the last act or omission of the defendant giving rise to the cause of action,” to dismiss the claims, finding that CTS’s last act occurred in 1987, when the property was sold.  Relying on CERCLA Section 9658, the Fourth Circuit re-instated the nuisance claims because it concluded that CERCLA pre-empted the North Carolina statute.

The Supreme Court reversed the Fourth Circuit, holding that the North Carolina statute was not pre-empted and that CERCLA Section 9658 was limited to “statutes of limitations.”  While noting that there is common ground between “statutes of limitations,” which create “time limit[s] for suing in a civil case, based on the date when the claim accrued,” and “statutes of repose,” which “put[] an outer limit on the right to bring a civil action,” “each has a distinct purpose and each is targeted at a different actor.”  The Court found that, when Congress passed Section 9658, the language it chose limited the provision to statutes of limitations.  Additionally, the Court found that CERCLA expressed neither any intent to provide “a general cause of action for all harm caused by toxic contamination” nor a clear intent to supersede traditional police powers of the states.

Two points are worth mention:

First, the CTS decision is not the “usual” CERCLA decision.  The decision does not alter the mechanism under which federal or state agencies investigate, characterize, and remediate properties.  Indeed, based on the case history, the groundwater contamination alleged in the CTS litigation was discovered by EPA in 2009, two years before CTS suit was filed.  In 2012, the involved property was added to EPA’s National Priorities List, a designation reserved for sites EPA has identified as being among its priorities.  Similarly, it does not alter the federal causes of action parties may use to recover costs related to their remediation activities.

Second, the CTS decision appears to be based on a straightforward reading of CERCLA.  The Court held that CERCLA does not preclude a state’s choice to have legislative statutes of repose which apply to certain categories of tort cases.  While a few states have these, the majority of states do not.[1]  Each of the federal environmental statutes – to a degree – seeks to shape state action.  There is no indication in CERCLA that it intended to “trump” state ability to form independent tort-related law for any situation related to contamination.  Had it been Congress’s intent to supersede all state statutes of repose related to actions related to contamination, Congress could have done so.  In the Court’s view anyway, the language Congress chose did not do so here.

[1] States with statutes of repose which were identified in the course of the CTS litigation include Connecticut, see Conn. Gen. Stat. § 52-584; Kansas, see Kan. Stat. § 60-513(b); North Carolinia, see N.C. Gen. Stat. § 1-52(16); and Oregon, see Or. Rev. Stat. § 12.115(1).  Alabama has a 20-year common-law statute of repose.  See, e.g., Abrams v. Ciba Specialty Chems. Corp., 659 F. Supp. 2d 1225) (S.D. Ala. 2009).
