ASTM Standards and PFAS….Not So Fast

Mar 23, 2022 | Due Diligence, Environmental, PFAS

On March 14, 2022, we reported on the EPA’s adoption of revised American Society for Testing and Material (“ASTM”) standards that would, for the first time, include a reference to PFAS. The ASTM changes would be significant for a wide array of entities, including investors, lenders, banking, insurers, and any parties contemplating an M&A. However, the notion of explicit ASTM standards and PFAS may have to wait, at least with respect to formal adoption by the EPA. With the comment period window closing in the coming weeks, it is anticipated that stakeholders will filed adverse comments, which will require the EPA to withdraw its final rule adopting the ASTM changes and send the rule to a public comment period.

ASTM Standards and PFAS Under E 1527-21

ASTM’s recent revisions to its existing “gold standard” for environmental due diligence – the Phase I environment site assessment – updated certain definitions, recommended processes, and for the first time include a reference to PFAS. On November 1, 2021, the ASTM’s environmental assessment, risk management, and corrective action committee (the E50 committee) released E 1527-21, which revises certain portions of the Phase I Environmental Site Assessment protocol. On March 14, 2022, the EPA adopted the ASTM PFAS standard in the Federal Register in its direct final rule.

Notably, E 1527-21 does include a reference to PFAS. While the ASTM PFAS changes may not go as far as some wished, the change nevertheless signals to anyone in the Phase I Environmental Site Assessment process that they should begin conducting PFAS assessments voluntarily. The ASTM change to the Phase I Environmental Site Assessment sets new requirements for complying with the All Appropriate Inquiries (AAI) rule, which sets certain requirements for determining environmental conditions on a property and the presence of contaminants. If a potential buyer follows the AAI rule, it may potentially be able to avail itself of certain defenses under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or any comparable state regulation. Part of the AAI rule requires parties to have conducted a Phase I Environmental Site Assessment in accordance with governing ASTM standards. If a Phase I identifies environmental issues or contaminants of concern, the parties should proceed to the Phase II process, under which remediation of the issue(s) takes place. Aside from being able to argue certain defenses if the property at issue becomes the subject of an environmental enforcement action or litigation, following the AAI rule also serves a practical purposes for parties involved in the transaction, as it allows them to better know the full scope of the risks of the deal that will be entered into.

Some of the more notable changes under E 1527-21 include:

  • The site examination requirements add further responsibilities on the parties to bolster customary practices now in place since the prior rule was promulgated;
  • Several changes to the information that must be contained in the written report;
  • The various hazard categories were more clearly defined so as to reduce confusion or misclassification of hazardous substances that are or may be present on the property;
  • The section detailing how to search historical records is significantly changed to include new standards for the use of historical sources, as well as general changes to language and definitions from the prior rule; and
  • A footnote that suggests including PFAS and other emerging contaminants in Phase I Environmental Site Assessments if states in which the Phase I is conducted define PFAS a “hazardous substances.

Delay In EPA Adoption

Reports have circulated recently that several groups intend to file adverse comments to the EPA’s final rule due to the fact that the EPA did not remove a reference to the prior ASTM standard (E1527-13), which adverse commenters believe undermines the update and the impact of the update. Essentially, comments will state that the wording of the EPA rule gives site assessors the option of using either the old standard (E1527-13) or the new standard (E1527-21), which was not the intent of the years-long process that the ASTM committee members in creating the new standard. The resulting confusion as to applicable standards will, adverse commenters believe, undermine the purpose of the new ASTM standard.

The comment period for the EPA’s rule closes on April 13, and adverse comments are expected before then.

ASTM PFAS Standards – Implications To Dealmakers

While the EPA’s formal adoption of the ASTM standard will be delayed by having to go through the public comments period, the release of E1527-21 nonetheless puts entities in the deal process on notice as to the “standard of care” that will be expected under due diligence processes with respect to PFAS.

Financial world parties (lenders, banks, equity firms) that traditionally receive Phase I Environmental Site Assessments as part of their due diligence or risk assessment process must begin to ask whether the assessments voluntarily considered PFAS issues. Even better, they should consider demanding the the assessments contain a PFAS evaluation component. Some states already classify certain PFAS as “hazardous substances.” The EPA’s PFAS Strategic Roadmap sets the clear goal to designate certain PFAS as “hazardous substances” under CERCLA. In doing so, CERCLA enforcement can be applied to pollution issues pre-dating the “hazardous substance” designation. EPA-mandated cleanups of sites on which there are “hazardous substances” can cost anywhere from hundreds of thousands to millions of dollars. Such significant costs place the stability of lending put forth for a property deal into jeopardy, increase risks to insurers covering the parties to the transactions, and increase financial risks to the parties to the deal. The best way to protect a deal and an investment in the long-term is to ensure that adequate PFAS considerations are taking place today before the deal is finalized.
