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.

Cannabis Prop 65 Liability: Lessons Learned from the Dietary Supplement Industry

The cannabis industry appears to be next on the liability “hit list” under California’s notorious Proposition 65 statute. In June 2017, more than 700 Prop 65 notices were served on California cannabis businesses. Companies in this emerging market should start mitigating risk under Prop 65 now. Fortunately, lessons can be learned from the dietary supplement industry’s expensive Prop 65 battles over the past decade.

California’s Prop 65, also known as the Safe Drinking Water and Toxic Enforcement Act, requires a warning on all products that contain chemicals known to cause cancer or reproductive harm, even in amounts a fraction of what is deemed safe by federal standards. Prop 65 has caused havoc within the dietary supplement and herbal product markets over the past decade, led by a cottage industry of “bounty hunter” attorneys who have weaponized the statute, ostensibly in the public interest but in reality as a lucrative for-profit business. These bounty hunters are now turning their attention to cannabis. Though amendments to the statute were adopted in 2016 for the purpose of reducing this abuse, Prop 65 litigation will continue and cannabis companies must stay vigilant.

Many businesses faced with the necessity of using a Prop 65 warning have no concern with the impact that a warning may have on sales or with consumer confidence in the product. After all, who would look twice at a Prop 65 warning on motor oil or insect repellent? Like the dietary supplement industry before them, however, many cannabis businesses will resist including a warning that the product contains a chemical known to cause cancer or reproductive harm. Many cannabis products rely on the consumers’ belief that the product is harmless and even therapeutic. For many, this will be an important business decision that may give rise to expensive mistakes − a decision should be made with an understanding of the basis for Prop 65 liability and exposure.

What Is Prop 65 and What Does It Require?

Prop 65 was passed by California voters in 1986 after an aggressive lobbying campaign by environmental and public health activists. The stated purpose of Prop 65 was to improve public health. The general consensus, however, is that Prop 65 has placed an undue burden on California businesses while achieving no significant impact on public health over the past 30 years.

As noted above, Prop 65 requires a warning on all products that contain chemicals known to cause cancer or reproductive harm. There are more than 900 such chemicals listed, and marijuana smoke has been included on the list since 2009.

For a warning to be acceptable under Prop 65, it must (1) clearly make known that the chemical involved is known to cause cancer and/or birth defects and/or other reproductive harm and (2) be given in such a way that it will effectively reach the person before he or she is exposed. The warnings must be “clear and reasonable,” meaning that the warning may not be diluted by other language. Various means of communicating the warning are allowed, including product-specific warnings on a posted sign or shelf, warnings on the product label or electronic warnings for internet purchases.

Important Exemptions

There are several important exemptions to Prop 65 that make a warning unnecessary. Businesses with nine or fewer employees are exempt from the statute. There also is an exemption involving chemicals that occur naturally in food. Lead, for example, will be considered naturally occurring only if it “is a natural constituent of a food” and is not added as a result of human activity such as pollution or poor manufacturing processes. The burden is on the company to prove the exemption, however, which is typically time-consuming and expensive.

Another important exemption is provided by “safe harbor” exposure levels for many chemicals on the Prop 65 list, below which no warning is required. The listed chemicals include additives or ingredients in pesticides, food, drugs and common household products. Most food contains at least some level of one or more of these substances. Prop 65 safe-harbor levels, however, are in many cases around 1,000 times lower than levels set by the Food and Drug Administration (FDA), Environmental Protection Agency (EPA) and World Health Organization (WHO). The exposure levels established by Prop 65 are often lower than what occurs naturally in fruits, vegetables, grains and even drinking water.

For example, the Prop 65 limit for lead is 0.5 mcg / day, which is below the amount of lead naturally found in many fruits, vegetables and herbs grown in non-contaminated soil. By comparison, the FDA allows 75 mcg / day and the European Union allows 250 mcg / day for lead. The European Food Safety Authority estimates the average adult consumes around 50 micrograms per day, which is 100 times the Prop 65 limit. It is nearly impossible to manufacture herbal products, including cannabis, without trace amounts of lead. Therefore, despite the “naturally occurring” exemption, discussed above, it can be dangerous to simply assume that an herbal product, including cannabis, complies with safe-harbor levels.

Only about 300 of the more than 900 Prop 65 chemicals have specific safe-harbor levels. For those chemicals without a safe-harbor limit, the burden will be on the cannabis business to establish that the subject chemical is within a safe range. This typically requires expensive testing, the results of which may be open to multiple interpretations as to whether a warning is required.

Determining the Exposure Level

Determination of the “exposure level” also is an important consideration. Prop 65 focuses on the level of a chemical to which the consumer is actually exposed. Although a product may have a very low amount of a chemical on the Prop 65 schedule that is below the safe-harbor level, liability under the statute may nevertheless be triggered based on the recommended serving size. It is advisable for companies to work with a laboratory that specializes in Prop 65 testing to determine the cumulative exposure level in order to verify the recommended serving size.

Enforcement of Prop 65

Prop 65 is enforced through litigation brought by the government or by private attorneys that “act in the public interest.” It is the threat of these private lawsuits that causes such consternation among those targeted with Prop 65 liability. After a 60-day notice period, the attorney may file a civil suit against the offending company. Typically, the plaintiff will demand that the defendant provide warnings compliant with Prop 65, pay a penalty, and either recall products already sold or attempt to provide health hazard warnings to those who purchased the products.

Though purportedly brought in the public interest, it is the collection of penalties and attorneys’ fees that in reality drives this litigation. Prop 65 allows individuals who bring suit to recover 25 percent of the penalties awarded, which by statute is calculated at $2,500 per violation per day. Amendments made to Prop 65 in 2016 allow for certain voluntary actions by the defendant – reformulation of the product, for example – in lieu of penalties. The threat of paying the plaintiff’s attorney’s fees makes litigating Prop 65 cases potentially very expensive. The attorney is incentivized to drag out the litigation, and the longer the case goes on, the more difficult it becomes to resolve because of the mounting fees.

This framework has created a cottage industry of Prop 65 “bounty hunter” lawyers who affiliate with “public interest” organizations that bring these cases for profit. According to the California Attorney General, 760 settlements were reported in 2016 with total settlement payments of more than $30 million. Attorneys’ fees accounted for 72 percent of that amount. The 2016 amendments to the statute have attempted to address these abuses to some extent by requiring a showing that the public benefits derived from the settlement are “significant” and by requiring contemporaneous record keeping for fees and costs sought to be recovered. Prop 65 litigation nevertheless continues to burden many industries in California, now including the cannabis industry. For Prop 65 liability, prevention is certainly less costly than a cure.
