The United States Environmental Protection Agency (EPA) in July of this year designated two PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemical types as “hazardous substances” under the federal Comprehensive Environmental Response Compensation and Liability Act (CERCLA, better known as the Superfund liability law), which has had a major impact in the ever-evolving environmental regulatory arena. PFAS substances are commonly referred to as “forever chemicals” because, according to the EPA, they are difficult to break down and can accumulate and persist in the human body for long periods of time. Because PFAS chemicals have been manufactured and used in a large variety of products for decades, the EPA states that they are found in water, air, fish and soil at locations around the globe. The Superfund designation is part of a larger EPA strategy to address PFAS contamination, including promulgation in April of this year of new and very strict standards for PFAS in drinking water. In addition, there has been movement by several states to regulate PFAS, including some that are imposing bans on use of PFAS chemicals in a growing range of products.

The American Society for Testing and Materials (“ASTM”) is expected to release a revised international standard for Phase I Environmental Site Assessments (“ESAs”) in December of 2021 that will clarify a number of key components of the standard and elevate the importance of per/poly-fluoroalkyl substances (“PFAS”).

Phase I ESAs are conducted by many parties when they become involved in the sale, acquisition, development, or financing of a piece of land, including developers, owners, and parties who provide loans for or serve as tax equity investors on renewable energy projects.  The Phase I ESAs allow those parties to get a glimpse into the environmental condition of the land and identify any potential contamination on-site.  Some of those parties – by acquiring an ownership or leasehold interest in the land, or by becoming an operator of the site – take on potential environmental liability if there have been releases on-site, including liability under the strict liability scheme of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”).  A defense to CERCLA liability is available if the party conducted certain diligence that complies with the United States Environmental Protection Agency’s All Appropriate Inquiries (“AAI”) standard, and if the party exercises appropriate care with respect to issues identified.  Environmental consultants prepare those Phase I ESAs and use the current ASTM standard as a guideline to prepare a thorough report and comply with AAI.

Recent Regulatory Steps

On January 14, 2021, on the eve of President Biden’s inauguration, EPA issued an advance notice of proposed rulemaking, seeking comment on whether PFOA and PFOS should be regulated under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and the Resource Conservation and Recovery Act (“RCRA”). This will likely lead to the designation of PFOA and PFOS as “Hazardous Substances” under CERCLA and RCRA. Such a designation will likely lead to EPA and the state agencies taking more aggressive action to investigate and identify new sites where PFAS may be a concern and also to review the status of existing sites where PFAS may be a concern that was not addressed in previous investigations or response actions and to potentially pursue response actions at such sites.  At this moment though there is only the interim policy that EPA provided to assist in addressing PFOA and PFOS groundwater contamination. The comment period on this advance notice just closed and we anticipate a proposed rulemaking in the near future.
