On Feb. 14, 2023, the Maine Department of Environmental Protection (MDEP) announced a much-anticipated proposed rule intended to clarify the notification requirements and sales prohibitions for products and product components containing intentionally added perfluoroalkyl and polyfluoroalkyl substances (PFAS). This reporting requirement has generated attention given its broad scope and “first out of the gate” nature. This article contains a summary of the guidance.

Cleanup costs under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are about to get a lot more expensive. The U.S. Environmental Protection Agency (EPA) announced on September 6, 2022, that it will propose to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), two of the most widely used per- and polyfluoroalkyl substances (PFAS), as hazardous substances under CERCLA. The rulemaking would also require entities immediately to report releases of PFOA and PFOS that meet or exceed the reportable quantity (RQ). This article discusses the proposal.

The scope of what diligence is due in any corporate transaction has evolved greatly over the past decade, particularly with respect to transactions involving chemical products. Once upon a time, transactional due diligence involving chemical products, whether ‘neat’ (pure) chemicals, formulations or end-use products, typically consisted of a phase I or phase II environmental site assessment (ESA) focusing on identifying contamination derivative of chemical releases into environmental media as effluent, emissions, fugitive releases or waste, as well as quantifying the potential for such releases to pose litigation risks or regulatory enforcement, or require costly remediation. Increasingly, parties to corporate transactions now continue to focus on these liabilities and on the compositional elements of chemical products themselves as potential sources of liability and commercial disruption. This article explains why the transition to chemical product due diligence has been slow and offers a few tips to help assess what diligence is due in corporate transactions involving chemical products.

Per- and polyfluoroalkyl substances (PFAS) are getting a lot of attention in the United States and globally. Their varied chemical properties make the categorization of “PFAS” into a single category chemically and scientifically questionable. Increasingly, the ability to make distinctions among this large chemical category is challenging, yet failure to do so could be unwise. This article provides information on PFAS, and offers a few suggestions to keep in mind when making business decisions.

The ubiquity of per- and polyfluoroalkyl substances (PFAS) and the manufacturing sector’s decades-long reliance on them to impart functionalities in a dizzying array of products put the investor between the proverbial rock and a hard place. PFAS varied chemical properties make the broad categorisation of ‘PFAS’ into a monolithic category of ‘forever chemicals’ chemically and scientifically questionable.

For better or worse, however, that is exactly what is happening today, and distinguishing between commercially promising and commercially risky PFAS chemicals is challenging. Yet, the ability to make this distinction could be the difference between a great investment and a commercially disastrous one. This article explores this difficult assessment, provides essential information on PFAS, and offers some suggestions to avoid making bad investment decisions.

The U.S. Environmental Protection Agency (EPA) announced on June 10, 2021, three actions intended to protect communities from per- and polyfluoroalkyl substances (PFAS), as covered in July’s column “EPA Announces Blockbuster PFAS Actions.” This column focuses on one of them: an ambitious proposal intended to obtain comprehensive data on more than 1,000 PFAS manufactured in or imported into the United States. As discussed in this article, the proposal’s scope is enormous.

When it comes to per- and polyfluoroalkyl substances (PFAS), the U.S. Environmental Protection Agency (EPA) is not messing around. The agency announced on June 10, 2021, three actions intended to protect communities from PFAS. This article summarizes the actions.
