Class Action Targets 3M and Chemours for Suppressing PFAS Risks in Carpeting

/in ,

Two Minnesota consumers who own PFAS-treated carpeting have sued 3M and Chemours, alleging that the chemical companies collaborated for decades to suppress information about the health and environmental risks of PFAS.

According to the complaint, the defendants knew that PFAS were dangerous as early as the 1950s but knowingly withheld evidence of their harms from EPA and the public.  The plaintiffs allege that when these companies shifted from using long-chain PFAS like PFOA and PFOS to shorter-chain variants like GenX and PFBS, they baselessly claimed that the shorter-chain variants were safer.  And even after many carpet manufacturers and retailers stopped making and selling carpeting containing PFAS, the complaint states that the defendants “continued to lie about the harms caused by [these] products.”

Products made by the defendants were used to treat carpets to make them stain- and soil-resistant.  However, the suit claims that carpet manufacturers were unaware that these products were dangerous, in part due to false or misleading safety data sheets provided by the defendants.  The proposed class action seeks to represent all persons who had carpeting installed prior to 2020, alleging that the defendants’ PFAS products were applied to “virtually all carpets manufactured in the United States” until that year.

The proposed class action’s claims are partially based on internal company documents released through other litigation, including a 2018 settlement reached between 3M and Minnesota over PFAS contamination in drinking water.  That case unearthed documents allegedly showing that 3M discouraged its scientists from discussing the chemicals in writing and stymied research efforts, despite knowledge that PFAS were severely toxic and widely present in human blood.

More large settlements were reached last year.  But the defendants “have not paid a dime for the grievous harms caused by carpets in homes and day-care centers infused with PFAS,” said the plaintiffs, who are seeking damages to replace contaminated carpeting.  These alleged harms include property damage resulting from PFAS emissions from the carpets, which reportedly continue throughout the carpet’s lifespan.

The suit alleges that the defendants violated the Racketeer Influenced and Corrupt Organizations Act as participants in a scheme to conceal PFAS harms for commercial gain.  The suit’s 127 counts also include a myriad of state law claims, including strict products liability and nuisance claims.

The complaint also includes allegations against PFAS manufacturer Daikin, which is not named as a defendant.

The case is Peterson v. 3M Co. (D. Minn.), No. 0:24-cv-0349.

EPA Releases Second Version of Interim Guidance on PFAS Destruction and Disposal

/in , ,

On April 8, 2024, EPA released the second version of its interim guidance on the destruction and disposal of PFAS and PFAS-containing materials.  The updated interim guidance builds on the initial guidance issued in 2020 by providing new recommendations for the management of PFAS-containing materials.

The updated interim guidance focuses on three categories of large-scale destruction and disposal technologies: underground injection, landfilling, and thermal treatment.  For each category, EPA identifies the technology with a lower potential for environmental release of PFAS when compared to other technologies within their category:

  • Permitted Class I non-hazardous industrial or hazardous waste injection wells (underground injection);
  • Permitted hazardous waste landfills (landfilling); and
  • Permitted hazardous waste combustors (thermal treatment).

However, each technology has drawbacks and is only suitable for certain types of PFAS-containing materials.  For example, EPA notes that new information suggest landfills may release more PFAS into the environment than previously understood, and that transportation logistics may limit the types and amounts of PFAS-containing fluids that can be inserted into Class I wells.

EPA emphasizes the limitations of available data and includes a list of prioritized research needs to inform future guidance.  High-priority research needs include information on releases from landfills and data on releases from thermal treatment units.  EPA describes a new analytical method, OTM-50, that it believes will better characterize the products of incomplete combustion.

In addition, the updated interim guidance presents a new evaluation framework designed to assess emerging technologies and determine their suitability for specific PFAS-containing materials. It also includes an updated list of tools to screen for potentially vulnerable populations living near likely PFAS destruction or disposal sites.

EPA was mandated to publish and triennially update the interim guidance by the FY 2020 National Defense Authorization Act.  More information on the updated interim guidance can be found in an EPA fact sheet.

Comments on the updated interim guidance are due October 15, 2024.

Coca-Cola Asks Judge to Dismiss Simply Juice PFAS Suit

/in ,

A proposed class action alleging that Coca-Cola’s Simply-brand juices contain PFAS does not state a plausible claim for relief, Coca-Cola told the Southern District of New York on July 31, 2024.

The plaintiff in Lurenz v. The Coca-Cola Co. alleges that laboratory testing revealed “widespread and uniform” PFAS contamination in Simply juices at levels detrimental to human health.  As a result, the claims made on Simply products—including that the beverages are “All Natural” and “made simply” with “all-natural ingredients”—would mislead a reasonable consumer, the most recent complaint asserts.

The court dismissed the initial complaint for lack of standing in June, but allowed the plaintiff to file a new complaint.  In response, Coca-Cola filed a letter requesting a conference before the company files another motion to dismiss.  The letter argues that the new complaint’s allegations are “even vaguer” than those previously dismissed, making it “impossible to tell” when the plaintiff purchased the contested products.  The plaintiff “still cannot show a concrete economic harm needed to establish Article III standing,” Coca-Cola says.

In addition, Coca-Cola argues that the new complaint still provides insufficient factual detail about the testing that revealed PFAS contamination, which was a factor in the earlier dismissal.  Even if the testing allegations are deemed sufficient, Coca-Cola asserts that the all-natural claims are not misleading.  “[N]o reasonable consumer would understand PFAS—a substance that is not intentionally added to the [juices]—to be an ingredient,” the letter states.

The case is similar to an ongoing suit against L’Oréal, the cosmetics company, for alleged PFAS contamination.  A blog post on that case, written after a dismissal due to standing issues, can be found here.

EPA Grants Petition to Address PFAS Created by Plastic Fluorination

/in , , , ,

On July 10, 2024, EPA granted a citizen petition from environmental groups encouraging EPA to take Toxic Substances Control Act (TSCA) section 6 action for three PFAS substances produced during the fluorination of plastic containers.

The petition alleges that the three PFAS—PFOA, PFNA, and PFDA—pose a variety of serious human health hazards, even at extremely low exposures.  The petition cites EPA’s December 2023 response to significant new use notices filed by Inhance Technologies (“Inhance”), a fluorination company, for substances including PFOA, PFNA, and PFDA.  As discussed in a previous blog post, EPA found that Inhance’s production of the three PFAS presents an unreasonable risk and ordered Inhance to stop producing the chemicals under TSCA section 5, which allows EPA to regulate new substances and significant new uses.

Inhance challenged EPA’s order.  In March, the Fifth Circuit ruled that EPA could not regulate Inhance under TSCA section 5 because Inhance’s fluorination process had been in place for decades; a blog post on the decision can be found here.  However, the court noted that EPA is free to regulate Inhance’s fluorination process under section 6, which allows EPA to restrict existing substances.  Unlike section 5, section 6 requires EPA to conduct a cost-benefit analysis that considers a substance’s benefits and what the economic consequences of regulation would be.

In its letter granting the petition, EPA said that the agency will initiate “an appropriate proceeding under TSCA Section 6 associated with the formation” of the three PFAS during plastic container fluorination.  As part of the proceeding, “EPA intends to request information, including the number, location, and uses of fluorinated containers in the United States; alternatives to the fluorination process that generates PFOA, PFNA, and PFDA; and measures to address risk from PFOA, PFNA, and PFDA formed during the fluorination of plastic containers.”

Maine PFAS Law Triggers Class Action Against BIC in California

/in , ,

Customers in California have filed a class action lawsuit against BIC USA, Inc. (“BIC”), a razor manufacturer, over allegations of PFAS use discovered through BIC’s compliance with a Maine PFAS reporting law.

In 2021, Maine enacted legislation requiring companies to disclose whether their products contain intentionally added PFAS by January 1, 2023.  Although a subsequent law extended this deadline to 2025, some companies had already submitted PFAS information to Maine’s Department of Environmental Protection.  According to the complaint, a Freedom of Access Act request by a public advocacy group revealed that BIC had disclosed the use of PFAS as a lubricant in its razor blades.

The plaintiffs argue that they would not have purchased BIC razors for the price they paid had they known they contained PFAS.  Without a disclosure to the contrary, the complaint asserts that “[n]o reasonable customer would expect that shaving razors would contain dangerous PFAS, which are indisputably linked to harmful health effects in humans.”

The lawsuit alleges violations of California’s Unfair Competition Law and False Advertising Law, among other claims.  The plaintiffs seek injunctive relief, compensatory damages, and punitive damages.

The Maine legislature substantially revised the state’s PFAS reporting requirements in April, discussed in a previous blog post.  Under the amended law, reporting requirements will only apply to “currently unavoidable uses” starting in 2032.

The case is Butler v. BIC USA Inc., N.D. Cal., No. 4:24-cv-02955, filed May 15.

Maine Revises PFAS in Products Legislation

/in ,

Maine’s reporting requirements for products containing PFAS will be narrowed, and incremental category-specific bans will be adopted under a new law enacted April 16, 2024.  The law, LD 1537, revises landmark 2021 legislation that implemented a general ban on the sale of products containing intentionally added PFAS starting in 2030 and mandated reporting in the interim.

Narrowed reporting requirements

The new law scraps the old law’s “general notification requirement,” which would have required manufacturers to report information on products containing intentionally added PFAS by January 1, 2023 (later delayed to 2025).  Under LD 1537, reporting will only be required for “currently unavoidable uses” beginning in 2032.

As was the case previously, Maine’s Department of Environmental Protection will be tasked with determining what uses are currently unavoidable.  The department solicited requests for proposals from manufacturers seeking currently unavoidable use determinations beginning in January of this year.  However, in light of the new law, the department says on its website that it anticipates currently unavoidable use determinations to begin in 2025.

New timeline for banned products

LD 1537 pushes back the general sales prohibition for products containing intentionally added PFAS from 2030 to 2032.  However, the new law introduces many product category-specific bans.  Certain categories will now be subject to more aggressive deadlines, and a few will not be banned until 2040.

The new sales bans for products containing intentionally added PFAS are as follows:

  • Effective January 1, 2026: cleaning products, cookware, cosmetics, dental floss, juvenile products, menstruation products, textile articles (excluding outdoor apparel for extreme wet conditions and textiles for watercraft, aircraft, or motor vehicles), ski wax, and upholstered furniture.
  • Effective January 1, 2029: artificial turf and outdoor apparel for severe wet conditions (unless it includes a PFAS disclosure).
  • Effective January 1, 2032: all other products containing intentionally added PFAS except for currently unavoidable uses and those subject to a ban in 2040.
  • Effective January 1, 2040: HVAC equipment, refrigeration equipment, refrigerants, foams, and aerosol propellants.

LD 1537 additionally excludes certain product categories from all requirements, including firefighting foams, medical devices/drugs, veterinary products, motor vehicles/motor vehicle equipment, watercraft, and semiconductors.

Other changes

Under the new law, products that do not contain intentionally added PFAS are still subject to the above bans if they are sold in a container that contains intentionally added PFAS.  Importantly, this includes fluorinated containers.

LD 1537 also increases the minimum number of employees for a manufacturer to be subject to reporting requirements from 26 to 101.

More information on LD 1537 can be found at Maine’s Department of Environmental Protection website.

EPA Sets Drinking Water Standards for PFAS

/in ,

Concentrations of six PFAS substances in drinking water will be regulated for the first time under new drinking water standards published by EPA on April 26, 2024.

The final rule sets individual maximum contaminant levels (MCLs) for PFOA and PFOS at 4 parts per trillion (ppt).  The agency found no evidence that any level of exposure to either substance is safe, setting aspirational maximum contaminant level goals (MCLGs) of 0 ppt for both.

The final rule also sets individual MCLs (and MCLGs) of 10 ppt for PFHxS, PFNA, and HFPO-DA (known by the trademark GenX).  Mixtures containing two or more of PFHxS, PFNA, HFPO-DA, and PFBS are subject to a hazard index-based limit.

Public water systems are required to conduct initial monitoring by April 2027, be compliant with the MCLs by April 2029, and conduct regular compliance monitoring.  Water systems must include detected PFAS in their annual reports and notify the public if a MCL violation has been detected.

EPA characterizes the regulation as flexible.  The final rule allows reductions in initial monitoring for most small water systems, using previously collected drinking water data to satisfy initial monitoring requirements, and reduced compliance monitoring based on sampling results.  Additionally, the final rule does not dictate how PFAS be removed.

In a press release, EPA said it expects that approximately 6-10% of water systems subject to the final rule may need to take action to meet the standards, reducing PFAS exposure for around 100 million Americans.

PEER and CEH Request Court Injunction Against EPA

/in , ,

On February 15, 2024, the Public Employees for Environmental Responsibility (PEER) and the Center for Environmental Health (CEH) filed a lawsuit against EPA in the U.S. District Court for the District of Columbia stating that EPA failed to comply with a Freedom of Information Act (FOIA) request. The two nonprofit environmental groups said in their claim that they had filed a FOIA request on January 5, 2023, for numerous documents regarding Per-and Polyfluoroalkyl Substances (PFAS), specifically long-chain perfluoroalkyl carboxylate (LCPFAC) substances, created during the fluorination of plastic containers by Inhance Technologies LLC. PEER and CEH claim EPA failed to comply with the FOIA request and are now requesting an injunction for the courts to order EPA to disclose all the documents.

In their complaint, the two groups asserted that a document-by-document review by EPA is inefficient and unnecessary and requested that EPA instead adopt a class determination to expedite disclosure. PEER and CEH acknowledge they have received four interim releases but have yet to receive the full release and “unredacted documents have been produced in accordance with the disclosure requirements of section 14 of TSCA”.

The complaint details the timeline of EPA’s response to the FOIA request.  PEER and CEH note that EPA used an “Unusual Circumstances” exception to the standard time allowed for responding to a FOIA with a new estimated competition date of August 3, 2023. A Continuing Unusual Circumstance letter from EPA pushed the response date back further to December 1, 2023. This is an issue of contention for PEER and CEH, as they state that the FOIA statute allows for 20 working days to comply with FOIA requests and only an additional 10 working days for unusual circumstances. 5 U.S.C. § 552(a)(6). Therefore, according to PEER and CEH, the original competition date should have been February 2, 2023, and then adjusted to February 16, 2023 after including 10 working days for unusual circumstances.

EPA Issues SNUR to Keep Inactive PFAS Out of Commerce

/in , , ,

Inactive PFAS chemicals can no longer reenter commerce without EPA approval under a final significant new use rule (SNUR) issued by EPA on January 11, 2024.

The 329 PFAS subject to the SNUR are currently designated as inactive on the Toxic Substances Control Act (TSCA) Inventory and are not subject to an existing SNUR.  (An inactive designation indicates that a substance has not been manufactured, imported, or processed since 2006, with a handful of exceptions addressed below.)  To identify these chemicals, EPA applied the same definition of PFAS the Agency used in its TSCA section 8(a)(7) PFAS reporting rule issued in October 2023, discussed in a previous Verdant Law blog post.

The SNUR requires companies to notify EPA via a significant new use notification at least 90 days before commencing the manufacture, import, or processing of any of these substances.  Upon receiving notification, EPA will assess whether the new use may present an unreasonable risk to human health or the environment and take appropriate action, if necessary, as required under TSCA section 5.

Import and processing of inactive PFAS-containing articles are exempt from the SNUR.  Covered PFAS also fall outside the scope of the SNUR when they are manufactured, imported, or processed:

  • As impurities;
  • As byproducts not for commercial use purposes;
  • In small quantities solely for R&D;
  • For test marketing purposes;
  • For use as a non-isolated intermediate; or
  • Solely for export from the United States.

To establish a significant new use, EPA must determine that the use is not ongoing.  Because the above uses do not result in an active designation on the TSCA Inventory, EPA could not conclude that there are no ongoing uses for these activities.

Federal Court Requests Scientific Information on Diseases Associated with PFAS Exposure

/in ,

Parties must gather scientific evidence on the human health effects attributable to PFAS exposure in drinking water, the U.S. District Court for the District of South Carolina ordered in the case In Re Aqueous Film-Forming Foams Products Liability Litigation MDL 2873 last week.  The multi-district litigation focuses on the health hazards posed by aqueous film-forming foams (AFFFs), which are used as fire suppressants and allegedly contain PFAS such as PFOA and PFOS.

Plaintiffs allege that AFFF use at military bases, airports, and other locations caused the release of PFAS into local groundwater, which then entered the water supply.  According to Judge Richard Mark Gergel’s order, the litigation now includes over 20,000 cases, the majority of which raise personal injury claims.

The court adopted a bellwether program for these claims, focusing on alleged connections between exposure and four diseases: kidney cancer, testicular cancer, hypothyroidism/thyroid disease, and ulcerative colitis.  However, Gergel wrote that those diseases only make up a “small minority” of personal injury cases.  To determine which of the other cases have merit, Gergel directed the parties to propose a case management order within 60 days that includes the following:

  • A date by which plaintiffs must identify diseases not addressed in the bellwether program that they allege are the result of exposure to AFFF-contaminated drinking water,
  • A date by which the parties must produce peer-reviewed articles that support or challenge an association between exposure to AFFF-contaminated drinking water and an identified disease,
  • A plan for a science day where the parties can present experts to address those associations and
  • A plan for selecting bellwether cases for those associations.

In a separate order, Gergel stated that the court would select 28 personal injury cases as bellwether cases from a list of proposed bellwether cases submitted jointly by the parties.
