D.C. Circuit Upholds EPA’s CERCLA Hazardous-Substance Designations for PFAS as State-Law Settlements Highlight Expanding Liability Landscape

September 15, 2026 — Ashleigh K. Myers, Amanda G. Halter, Jillian Marullo & Anthony B. Cavender - 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 the 2024 designation by the U.S. Environmental Protection Agency (EPA) of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). (See Chamber of Commerce of the United States of America, et al. v. EPA, No. 24-1193 (D.C. Cir. Aug. 18, 2026).) The decision leaves EPA’s PFOA and PFOS hazardous substance designations in place and provides guidance on the scope of EPA’s authority to make future hazardous substances designations under CERCLA Section 102(a). The decision also likely resolves a challenge to the rule that has spanned two presidential administrations. After taking office, the Trump administration had obtained an abeyance of the litigation challenging the Biden-era rule while EPA reconsidered its position. In September 2025, EPA informed the court that it had decided to retain the designations, while signaling that it would work with Congress and industry to address CERCLA liability concerns for “passive receivers.” The litigation then resumed, with the current Administration defending the rule.

Daily Journal Publishes Article by Brenda Radmacher on Proposed Overhaul of California Construction Defect Law

June 29, 2026 — Brenda Radmacher - The Construction Seyt
Daily Journal (California) featured an article by Construction Law partner Brenda Radmacher, “A new path for construction defects in California.” The piece, published on June 15, 2026, examines Assembly Bill 1903 and its potential to significantly reshape California’s construction defect framework, particularly for common interest properties. The article highlights how AB 1903 would overhaul the state’s current right-to-repair system by mandating completion of prelitigation procedures, raising requirements for defect claims, strengthening developers’/builders’ rights to repair, and introducing a voluntary “certified building” program. The legislation aims to rebalance competing interests by reducing litigation-driven costs while preserving protections for homeowners. Read the full story...

For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

How Mobile Tools Are Capturing Safety Data on Jobsites

April 08, 2026 — Michael Bruns - Construction Executive
Traditionally, construction safety management is “reactive compliance”—reporting on an incident, filling out a form on paper or electronically, taking a picture and filing it away for compliance purposes. Safety management is shifting from reactive to proactive. Forward-thinking companies are using data and leading indicators to identify risks before incidents happen, not just document injuries after the fact. Mobile tools have completely changed the way safety operations work on construction sites, enabling that transition to proactive safety management.

Safeguarding Your Privileged Construction Information With a Clawback Agreement

June 08, 2026 — Laura Fraher - Construction Executive
For contractors and construction executives, a dispute that escalates to litigation brings risks that go well beyond the jobsite. When a dispute escalates to litigation, the attorney-client privilege is a critical protection to safeguard your interests. Disclosing privileged material can undermine your litigation position and, in some cases, negatively impact your business. In the construction context, this often includes sensitive communications about project delays, defect investigations, safety incidents or payment disputes—materials that can significantly impact both liability and reputation. During litigation, the discovery process requires the exchange of documents and data with your adversary. If privileged materials are disclosed to your adversary during discovery you risk the waiver of your privilege, which in plain terms means you lose the protection of the privilege and make the privileged information, and in some cases all other information related to the same subject matter, available to your adversary. It is critical that your attorney take steps to protect against the unintentional disclosure of privileged materials during discovery to avoid a waiver.
