EPA Reopens Pandora’s Box with CERCLA Designations of PFOA & PFOS; Seeks to Minimize Apprehension with Enforcement Policy

As our readers are likely familiar from our past blog posts here, here and here, in September 2022, EPA proposed to designate PFOA and PFOS as hazardous substances under section 102(a) of Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

Now, EPA has made it final: the agency has designated perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers, as hazardous substances (See Pre-Publication Notice).

EPA concluded that designation of those two substances is warranted “because both …

Fifth Circuit Tells EPA 40-Year-Old Fluorination Process isn’t ‘New’

Inhance Technologies is a company that has been fluorinating plastic containers using the same process since 1983. The fluorination process creates a barrier that keeps dangerous substances from leaching out of their containers, and keeps outside substances from permeating in. The U.S. EPA began investigating Inhance after the presence of perfluoroalkyls (PFAS) was detected in an insecticide that was stored in a container fluorinated by Inhance.

After confirming that Inhance’s fluorination process resulted in the creation of PFAS, the EPA issued Inhance a Notice of Violation …

Will Industry Push Back Proactively on Potential PFAS-Use Restrictions?

Over the past seven years, our blog has reported extensively on PFAS developments, litigation, and regulations — most of which has focused on the attention surrounding potential risks associated with PFAS, and the scrutiny given to that chemical class by the U.S. Environmental Protection Agency.

Today we are providing a wrinkle seldom seen recently in the PFAS world: a proposed law that would protect PFAS uses.  

This week, state of Indiana senators chose to abandon a bill that reportedly would have excluded thousands of the …

EPA Adds Seven More PFAS To Toxic Release Inventory List

As our blog has reported a number of times, the Environmental Protection Agency announced an ambitious national strategy to address per- and polyfluoroalkyl substances (PFAS). Dubbed a “roadmap,” the EPA says that it is centered on three guiding strategies focused on research, restrictions, and remediation. Specifically: “Increase investments in research, leverage authorities to take action now to restrict PFAS chemicals from being released into the environment and accelerate the cleanup of PFAS contamination.”

As part of this plan, the EPA last week announced the …

EPA Issues Automotive Trends Report, Noting Record Improvements in CO2 Emissions and Fuel Economy

To close out 2023, the US Environmental Protection Agency issued its annual Automotive Trends Report, which provides the public with information about vehicle greenhouse gas (GHG) emissions, fuel economy, technology data and innovation, and auto manufacturers’ performance in meeting the EPA’s GHG emissions standards. EPA has been collecting this information since 1975.

According to EPA, new vehicle CO2 emissions and fuel economy had the biggest annual improvement of the last nine years, reaching record low CO2 emissions and record high fuel economy. In model …

Doomed from the Start: Sixth Circuit Extinguishes Hardwick Class-Action PFAS Litigation

“Seldom is so ambitious a case filed on so slight a basis.”

That was the first sentence of Judge RaymondKethledge’s opinion vacating a district court order that certified a class of over 11 million Ohio residents who alleged various companies put their health at risk by manufacturing and selling products containing PFAS.  The panel of three judges on the U.S. Court of Appeals for the Sixth Circuit— Kethledge, Thapar, and Mathis — instructed the district court to dismiss this much-talked-about case for lack of jurisdiction. …

Next On EPA’s Chopping Block: Trichloroethylene

The Environmental Protection Agency has proposed a risk management rule as part of the Toxic Substances Control Act (TSCA) that would ban the production, processing and distribution of trichloroethylene (TCE) for all uses. TCE is used in a variety of applications, including cleaning and furniture-care products, paints and coatings, solvents, laundry and dishwashing products, degreasers, lubricants, brake cleaners and tire-repair sealants. 

According to EPA, the proposed rule is meant to address “the unreasonable risk of injury to human health presented by [TCE]” associated with its …

CPSC Sets its Sights on PFAS in Consumer Products, Bringing Future Regulation into Focus

The Consumer Product Safety Commission (CPSC) recently published a request for information (RFI) on per- and polyfluoroalkyl substances (PFAS) “used in commerce or potentially used in consumer products,” and as directed toward information on “potential exposures associated with the use of PFAS in consumer products, and potential human health effects associated with exposures to PFAS from their use in consumer products.”

This RFI concerns “consumer products” which includes products used in, or around, the home or school that are subject to CPSC jurisdiction under the Consumer …

Steel Beats Glass and Plastic, All Beat Paper: New Study Finds PFAS In Various Types Of Drinking Straws

A study published last week by the Food Additives & Contaminants: Part A journal — a journal that publishes on natural and man-made food additives and contaminants in food and the animal feed chain and is an affiliated journal of the International Society for Mycotoxicology — might make people think twice when selecting straws for their drinks.

The study — titled “Assessment of poly- and perfluoroalkyl substances (PFAS) in commercially available drinking straws using targeted and suspect screening approaches,” — makes some interesting findings on …

U.S. Geological Survey Study Warns 45 Percent of Tap Water in United States Could Contain PFAS

Motivated by “the quality and sustainability of drinking-water” due to rising water demand concerns in the United States, as well as “increasing contamination of drinking-water resources, and a growing understanding of potential human-health consequences associated with exposures to contaminants,” the U.S. Geological Survey recently conducted a study on the prevalence of PFAS in tap water.  

To better understand human exposure to PFAS at the point-of-use, the authors conducted a standardized analytical survey of PFAS nationally.

“The overall objectives of the study were to (1) directly …
