EPA Incites Further Controversy Proposing to Designate Forever Chemicals Under CERCLA

While critics may say the federal government has been slow to react to PFAS, last week the EPA took its most aggressive stance — publishing its notice for a proposed federal rule to designate two specific PFAS compounds, PFOA and PFOS, as “hazardous substances” under the Comprehensive Environmental Response Compensation and Liability Act (CERCLA), and now the clock is ticking. 

Found in surface water, air, soil, and even more recently food packaging, PFOA and PFOS were used pervasively in American manufacturing beginning in the 1940s for their durability, heat/grease resistance, and waterproof nature, and quickly assumed the nomenclature “forever chemicals” because of their remarkable inability to decompose. 

When talking shop, lawyers, insurance carriers, and manufacturers alike have labeled PFAS the ‘emerging contaminant’ to watch out for …

EPA Proposes to Designate PFOA and PFOS as Hazardous Substances under CERCLA

Friday of last week the U.S. Environmental Protection Agency (“EPA”) published a proposed rule that would designate 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 (commonly known as CERCLA). The designations, if finalized, could have direct and indirect impacts on a range of individuals and companies, as well as the federal government itself.

The five broad categories of entities potentially affected by this designation as …

EPA Previews 2021 List of Toxic Release Inventory

On July 28, 2022, the Environmental protection Agency (“EPA”) released its preliminary 2021 Toxics Release Inventory (“TRI”).  The purpose of the TRI is to give the public critical information regarding chemical releases, waste management, and pollution prevention undertaken at both federal and industrial facilities in the United States.  

The TRI program was created by Congress in 1986 as part of the Emergency Planning and Community Right to Know Act.  Chemicals that are covered by the program include those that have adverse health or environmental …

Trade Association Submits Challenge to EPA’s New PFOA and PFOS Health Advisories

As reported in our blog back in June, the Environmental Protection Agency unveiled new drinking-water health advisories (HAs) for PFAS contaminants. Specifically, the advisories drastically reduced acceptable PFOA and PFOS water levels from 70 parts per trillion (set in 2016) down to 0.004 parts per trillion for PFOA and 0.02 parts per trillion for PFOS.  

These new advisories, however, are already the subject of attack. Last week, a leading trade association filed a petition challenging these new HAs.  

The petition was filed with the U.S. …

New ASTM Standard Released for Phase I Environmental Site Assessments

For nearly two years, a task force comprised of various environmental professionals has been working on revisions to the American Society for Testing and Materials (ASTM) International Phase I Environmental Site Assessment (Phase I) Standard E1527-13, which is used by prospective purchasers in real estate acquisitions in order to satisfy the All Appropriate Inquiries (AAI) requirements under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

Purchasers must meet the AAI requirements in order to establish the innocent landowner, contiguous property owner, or bona fide …

EPA Releases Final Toxicity Assessment for GenX Chemicals

On October 25, 2021, the U.S. Environmental Protection Agency released its final human health toxicity assessment for hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt (referred to as “GenX chemicals”). HFPO dimer acid and its ammonium salt are the major chemicals associated with the processing aid technology developed by DuPont with the trade name GenX. GenX chemicals are part of the PFAS class, which replaced perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) that are no longer used in the United States. However, the …

ATSDR Releases Final Guidance on Perfluoroalkyls

As promised in our November 2018 blog post, “ATSDR PFAS Update: No Final Report Yet, But Further Guidance on Minimal Risk Levels and Drinking Water Concentrations,” we are providing an update on the Agency for Toxic Substances and Disease Registry’s recent release of its final Toxicological Profile for Perfluoroalkyls (Tox. Profile). This represents the ATSDR’s final guidance on these substances.

The purpose of the toxicological profile is to “succinctly characterize[] the toxicologic and adverse health effects information for these toxic substances…,” which are developed under …

A Change is Gonna Come … (and it’s kinda sorta already here)

The legendary singer/songwriter Sam Cooke may have intended for his 1964 anthem, “A Change is Gonna Come,” to be a protest song to surreptitiously fuel the civil rights movement and its pursuit of social justice, but little did he know the soulful R&B melody may realize its revival in the Biden administration as the U.S. Environmental Agency’s (EPA’s) new battle cry for environmental justice.

The EPA defines environmental justice (EJ) academically as “the fair treatment and meaningful involvement of all people, regardless of race, color, national origin, …

EPA Releases Updated Toxicity Assessment for PFBS

On April 8, 2021, the U.S. Environmental Protection Agency (EPA) released an updated toxicity assessment for perfluorobutane sulfuric acid (PFBS). This assessment comes as part of the EPA’s larger PFAS Action Plan, aimed to increase the amount of research and publicly available information on chemicals in the PFAS family.

PFBS, which is part of the larger group of PFAS compounds, is a replacement chemical for perfluorooctane sulfonate (PFOS), which is no longer used in United States manufacturing. PFBS is mainly used as surfactants and repellants …

Empire State Adopts MCL for 1, 4-Dioxane, PFOA, and PFOS

On July 30, 2020, New York’s Public Health and Health Planning Council voted in support of maximum contaminant levels (MCLs) for PFOA and PFOS—the two most well-known per- and polyfluoroalkyl substances (PFAS). The Council voted to set the MCLs for both chemicals at 10 parts per trillion—among the lowest levels adopted by any state, and significantly lower than the U.S. EPA’s current guidance levels of 70 ppt.

Another chemical—1, 4-Dioxane—also has an MCL of 1 part per billion now. New York announced that this regulation …
