From CERCLA to Drinking Water: D.C. Circuit’s PFAS Ruling Enters a Second Regulatory Fight

October 06, 2026 — Ashleigh K. Myers, Amanda G. Halter & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
On August 18, 2026, a unanimous panel of the U.S. Court of Appeals for the D.C. Circuit upheld EPA’s designation of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). In Chamber of Commerce of the United States v. EPA, the court rejected challenges to EPA’s interpretation of CERCLA Section 102(a), the adequacy of its notice and comment process, its analysis of costs and benefits, and its decision to proceed despite uncertainty about future response actions and costs. This decision is already being invoked in a separate D.C. Circuit challenge to EPA’s 2024 PFAS drinking water rule promulgated under the Safe Drinking Water Act (SDWA). Six days after the CERCLA decision, respondent intervenors cited it as supplemental authority in American Water Works Association v. EPA, No. 24-1188, ahead of oral argument scheduled for September 18, 2026. The Chamber of Commerce decision may assist the respondent intervenors on certain notice and comment and economic analysis arguments, but its significance should not be overstated. The principal challenges to the standards for the four PFAS subject to EPA’s Hazard Index-based maximum contaminant level (MCL) turn on requirements specific to the SDWA, and EPA itself now agrees that those provisions were promulgated through an unlawful process.

U.S. Supreme Court Decision May Negate State Law Requirement to File a Certificate of Merit with the Complaint in a Federal Action Against a Design Professional

April 27, 2026 — Christopher Olsen & Phillip Boldt - ConsensusDocs
To deter frivolous and unfounded claims against design professionals, states throughout the country have enacted statutes which generally require litigants to furnish a formal certification of merit (“COM”) from a qualified expert or face potential dismissal of their lawsuit. These COM statutes can impose a significant front-end burden on claimants who must pay an expert to review project records, interview the project team, and prepare a formal report before the lawsuit can be filed—often regardless of the amount in controversy. However, in light of a recent U.S. Supreme Court decision in a medical malpractice case, most, if not all of these statutes, may no longer be enforceable in federal court. This article examines the recent decision in Berk v. Choy, 146 S. Ct. 546 (2026), the decisions thus far which have applied Berk to invalidate COM statutes, and other categories of statutes applicable to the construction industry which may face a similar fate. The U.S. Supreme Court Decision (Berk v. Choy) In Berk, the plaintiff, Harold Berk, sued a doctor for medical malpractice under Delaware law in Delaware federal court. 146 S. Ct. at 551. Under Del. Code, Tit. 18, § 6853(a)(1), an affidavit of merit (like a COM) must accompany a complaint alleging medical malpractice. Id. Berk failed to include an affidavit of merit with his complaint. Id. at 552. Applying Delaware state law, the federal court dismissed Berk’s medical malpractice claim. Berk appealed to the Third Circuit, arguing that the affidavit of merit required by § 6853(a)(1) is unenforceable in federal court because it is more onerous than the Federal Rules of Civil Procedure. The Third Circuit affirmed the District Court’s ruling, finding § 6853(a)(1) enforceable in federal court.

Engineering Seals Versus Contracts ‘Under Seal’ (Two Very Different Things)

May 05, 2026 — Melissa Dewey Brumback - Construction Law in North Carolina
Recently, I was asked by a reader to explain the difference between a document that is ‘sealed’ by an engineer (or architect) and one that is signed ‘under seal’. This question prompted this post, as others may also be wondering about the distinction. [Hi Ed! Thanks for your question] Professionals have ‘seals’ that show that they are registered (Engineers) or licensed (Architects). As most of you likely know, your professional seal is something that is hard won and which is used when—and only when—your plans were made by you or someone under your direct supervisory control. Your signature represents that you were in responsible control over the documents, and that they have met the required professional standard of care. (21 NC Admin Code 2-0206 (a)(11)).
