DTSC Approves Preliminary Report on 6PPD Alternatives

This August, the California Department of Toxic Substances Control (DTSC) approved a revised stage 1 alternatives analysis report for 6PPD (CASRN 793-24-8) from the U.S. Tire Manufacturers Association (USTMA).  The preliminary report identified seven potential 6PPD alternatives for use in tires, which will be further assessed in the stage 2 alternatives analysis report due in August 2026.

6PPD, or N-(1,3-Dimethylbutyl)-N’-phenyl-p-phenylenediamine, has been used as an anti-degradant in tires since about the 1950s.  In 2020, it was discovered that 6PPD has a transformation product, 6PPD-quinone, that is extremely toxic to salmon and other aquatic species.  According to USTMA’s website, the organization “is not aware of any new motor vehicle tires available today that do not contain 6PPD.”

The seven potential 6PPD alternatives identified by the preliminary report are 7PPD, IPPD, 77PD, CCPD, specialized graphene, octyl gallate, and Irganox 1520, selected based on available information on potential hazards, performance, and chemical and physical properties indicative of exposure potential.  7PPD, IPPD, 77PD, and CCPD come from the same chemical family as 6PPD.  Eliminating the use of 6PPD without replacement is not an option, according to the preliminary report.

The stage 2 alternatives analysis will include a “more in-depth evaluation of hazard and exposure potential,” including additional evaluation of potential transformation products.  “At the end of [stage 2], we are optimistic that we will have identified one or more possible alternatives that hold promise to replace or materially reduce 6PPD in motor vehicle tires,” the preliminary report states.

The initial report was revised due to a notice of deficiency issued by DTSC, which was described by USTMA as “a standard step in the alternatives analysis process” that allows “regulators to provide suggestions and seek clarification about certain parts of a preliminary submission.”  Octyl gallate and Irganox 1520 were added to the list of potential alternatives in the revised report.

DTSC added 6PPD to the list of Priority Products under California’s Safer Consumer Products Program effective October 2023, prompting the alternatives analysis.  The following month, EPA granted a Toxic Substances Control Act citizen petition requesting that EPA take action to prohibit its use in tires.  EPA has since proposed a data call for substances including 6PPD-quinone, discussed in a previous blog post.

Maine PFAS Law Triggers Class Action Against BIC in California

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

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.

State of Washington Regulates PFAS In Lieu of Cosmetics Ban

A proposal in Washington state has stalled in the state House, after passing their Senate, that would have banned cosmetics that contain phthalates, formaldehyde, and PFAS.   The proposal, Senate Bill 5703, states that legislature finds certain chemicals in cosmetic products to be linked with various negative health effects, such as cancer, birth defects, and damage to the reproductive system. It further states that if enacted, it would have prohibited the sale and distribution of any cosmetics containing these and an additional 31 different substances such as ortho-phthalates, phenolic compounds, parabens, and lead compounds beginning January 1, 2025.

Although Senate Bill 5703 did not progress, the governor did sign into law House Bill 1694, which allows the state department of ecology to recognize and regulate consumer products containing PFAS.  The bill gives the ecology depart the authority to restrict PFAS product to any limit.   The state’s department of ecology is directed to determine an initial set of regulatory actions regarding PFAS consumer products by June 1, 2024 and must adopt rules to implement the initial set of determinations of regulatory actions by December 1, 2025.  Washington has also created a $266,00 fund for identifying and testing cosmetics for the purpose of determining which cosmetics present harmful effects.

Washington is not the first state to ban hazardous substances from cosmetics.  In 2020, California passed a ban on cosmetics containing harmful substances, identifying some PFAS chemicals.  Maryland took the same course of action in 2021.  In addition, several other states, such as New Hampshire, Minnesota, Michigan, and Maine have begun drafting legislature to restrict PFAS in cosmetics.

Recent State Activity on PFAS Regulation

Since January 2022, many states have passed and proposed dozens of laws regulating PFAS substances.  These legislative efforts address topics including setting drinking water standards for PFAS, banning PFAS in consumer products, banning or restricting the use of firefighting foams containing PFAS, and adding PFAS substances to toxic and hazardous substances lists.

Virginia and Washington will soon adopt regulations establishing maximum contaminant levels for drinking water.  Indiana and Rhode Island have also proposed doing so.  California is considering legislation that would establish a Central Basin Communities water fund that would, in-part, offset treatment costs of PFAS-contaminated public water systems.

Minnesota, California, and Rhode Island have proposed legislation that would ban the use of PFAS in consumer products.  Products that would be subject to these bans range from cosmetics and cookware to carpets and clothing.

Arkansas, California, Illinois, Maine, and Louisiana have passed laws banning or restricting the use of firefighting foams containing PFAS.  Rhode Island and Ohio have proposed legislation that would restrict the use of firefighting foams.

Minnesota has added PFAS substances to its list of Toxic and Hazardous Substances.  California has added PFAS to the list of substances subject to Prop 65.  A Rhode Island bill would include PFAS in the definition of “hazardous substances” for purposes of industrial property remediation.

Legislative efforts have also addressed notice requirements.  Maine enacted legislation that requires manufacturers to provide notification if any personal, residential, commercial, or industrial product contains PFAS.  A bill pending in the California General Assembly would create a publicly accessible registry of products containing PFAS.  The bill would also require manufacturers to register PFAS-containing products.  A Minnesota bill would require manufacturers of products for sale in the state that contain intentionally added PFAS to provide written notice of the PFAS, its amount, and its purpose.

Other legislative proposals would enact the following:

  • A prohibition on products containing PFAS from being classified as recyclable.
  • A requirement for state-owned solid waste disposal facilities to establish leachate treatment to reduce PFAS.
  • A requirement for screening for PFAS in sludge or sludge-derived compost that is applied to land.
  • A requirement to adopt groundwater quality standards for certain PFAS.
  • A prohibition on the sale of products labeled as “compostable” or “home compostable” if it has a total organic fluorine concentration greater than 100 parts per million (ppm).

Legislators in other states following example set by CA's Safer Consumer Products regulations.

California led the way in state-level regulation of chemicals in products, and now, other states are beginning to follow its example. Bills pending in both Massachusetts and Vermont are modeled after California’s Safer Consumer Products (SCP) regulations.

In Vermont, the State Senate yesterday voted to approve S. 239, a bill which has provoked controversy in the state and must pass final approval in the Senate today before moving to on to the House. Last week, the Massachusetts Joint Committee on Environment, Natural Resources and Agriculture held a hearing on H. 235, which would establish a SCP-like program. The proposals in both states entail creating a list of “priority” chemicals, as in the California program, which would likely be based on existing authoritative lists. Both bills also call for manufacturers to conduct alternatives assessments for certain products containing priority chemicals, and authorize state regulators to ban the sale of certain products. The Vermont bill provides for companies to apply for a waiver, and the Massachusetts bill provides for a range of regulatory responses besides an outright ban.

Various state legislatures are also considering more limited proposals targeting chemicals in children’s products, including Minnesota’s H.F. 605 and Connecticut’s S.B. 126.
