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.

"Resilient Rebuild Hub" Helps Wildfire-Impacted Homeowners Build Back Stronger

September 21, 2026 — California Nevada Cement Association
NEWPORT BEACH, Calif., Sept. 21, 2026 /PRNewswire/ -- When homeowners in a fire-ravaged Pacific Palisades neighborhood banded together last year to rebuild with fire-hardened materials rather than standard wood framing, they weren't just rebuilding houses: they were rewriting the playbook for how California communities can rebuild after wildfire. Today, the Building with Resilience effort is making that playbook available to every homeowner facing the same decision with the launch of its new Resilient Rebuild Hub for exploring fire resistant, non-combustible construction options. The Resilient Rebuild Hub helps homeowners understand options for fire-resistant, concrete-based construction and connect with architects, engineers, and contractors who can build them. This includes six noncombustible building systems:

• Insulated Concrete Forms (ICF): stackable, high-density foam blocks filled with concrete which save 20-50% on monthly heating and cooling costs, reduce outside noise by up to 80%, offer exceptional earthquake performance and 4-hour fire resistance rating.
• Insulated Composite Concrete Forms (ICCF): similar formwork to ICF construction with composite materials that enhance strength, simplify installation, and improve long-term performance.
• Concrete Masonry: strong, durable wall systems used for decades across California and the U.S.
• Precast Insulated Sandwich Panels: a complete building enclosure system consisting of two layers of concrete separated by a continuous layer of rigid insulation.
• 3D Shotcrete: air-sprayed concrete for strong, fast, and versatile wall systems that enable a high degree of artistic freedom together with unparalleled fire resistance.
• 3D Concrete Printing: the cutting edge of residential construction, a large-scale robotic 3D printer "squeezes" a specialized concrete mixture layer by layer to allow for organic, curved designs that are often too expensive or impossible to build with traditional methods. The Resilient Rebuild Hub is available now at buildingwithresilience.com/how-to-build. Each part is free to access and includes case studies, technical resources, and a directory of architects, engineers, and contractors experienced in each building method. CNCA is a not-for-profit organization committed to developing sustainable and economical construction solutions for California and Nevada with an emphasis on the use of cement and concrete. For more information, visit www.cncement.org. CalCIMA is a trade association for the construction and essential mineral industries in California, including aggregate, essential and rare earth minerals, ready mixed concrete, and asphalt producers. In all, there are about 70 producer member companies that include 500 production sites in every county of California. Our members also include more than 100 suppliers and service providers to the industry. Founded in 1930, the National Ready Mixed Concrete Association (NRMCA) is the leading industry advocate with a mission to provide exceptional value for our members by responsibly representing and serving the entire ready mixed concrete industry through leadership, promotion, education and partnering to ensure ready mixed concrete is the building material of choice.

  ACEC Research Institute Report: Real Risk of AI Isn’t Technology. It’s the Org Chart.

  September 01, 2026 — ACEC Research Institute
  WASHINGTON (August 19, 2026) – The ACEC Research Institute today released Leading Through AI Risk: The Enterprise Framework for Engineering Firm Leaders, a new study finding that the most significant risks artificial intelligence poses to engineering firms are organizational rather than technological, and that firms treating AI as an IT initiative are managing the wrong issue. The report, part of the Institute’s yearslong Firm of the Future initiative, combines an extensive literature review with in-depth interviews of 21 leaders drawn from engineering firms, public infrastructure owners, technology vendors, insurance and legal professionals, licensing and regulatory agencies, and AI consultants. The report groups AI risk into eight interconnected domains:
  • technical reliability and model risk
  • professional liability and standard of care risk
  • data governance, privacy, and intellectual property risk
  • organizational and workforce risk
  • ethical, regulatory, and reputational risk
  • operational and cybersecurity risk
  • financial and business model risk
  • strategic leadership and enterprise governance risk
  The last serves as the integrating domain through which firms coordinate responsible AI adoption enterprise wide. The report stresses that firms do not experience these risks one at a time. Weak oversight may create legal liability. Workforce gaps may affect quality assurance. “Understanding these interactions,” the study notes, “is often more important than understanding individual risks independently.” About the ACEC Research Institute The ACEC Research Institute is the independent research arm of the American Council of Engineering Companies (ACEC). Its mission is to fund and deliver research to equip the engineering industry with actionable intelligence on the issues critical to its success. Learn more at www.acecresearchinstitute.org.

  Steel Cooling: Steel Costs Steadily Decline After Pandemic Price Shock

  May 12, 2026 — Construction Executive
  Steel prices have continued trending downward after several years of volatility, according to Gordian’s latest analysis based on RSMeans Data. After dramatic spikes during the pandemic-era supply disruptions, the market has gradually stabilized as supply chains improve and demand softens in some construction segments. However, selective volatility and tariff uncertainty continue to influence pricing across the sector. Key findings from the report include:
  • Steel prices declining: The national average price of structural steel fell to about $2,343.93 per ton in January 2026, down 5.38% from the previous quarter and 7.18% year over year.
  • Longer-term price correction: Steel costs have been trending downward since 2024 after earlier volatility driven by inflation, supply shortages and global demand swings.

  Kahana Feld Obtains Favorable Result in High-Exposure NY Premises Liability Case

  June 15, 2026 — Leigh Katz - Kahana Feld
  Kahana Feld partner Leigh Katz obtained a significant victory in a recent matter involving a videotaped alleged trip and fall on the sidewalk in front of the client’s commercial residence. The plaintiff claimed he suffered a knee injury that necessitated surgery, along with other assorted injuries that prevented him from continuing high-level athletic activities. Leigh was able to demonstrate that the fall was staged and received a voluntary discontinuance with prejudice. At mediation, Leigh emphasized that KF’s expert witness challenged the plaintiff’s claim that the fall was caused by a sidewalk height differential after reviewing the videotape footage and determining the plaintiff’s fall began before his feet made contact with the alleged defect. Based on this analysis, the expert concluded the reported height differential did not initiate the fall, which supported KF’s position that the incident depicted in the video was unrealistic and appeared staged.
