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.

The Most Expensive Signature to Not Get: Why Change Orders Matter

August 16, 2026 — Kathryne E. Baldwin - Wilke Fleury
George Bernard Shaw has a quote we use a lot in my family: “The single biggest problem in communication is the illusion that it has taken place.” This is pertinent to contractors and homeowners alike because the cost of failing to get proper signatures on documents like construction contracts, and particularly, change orders, is heavy. Both contractors and homeowners are in the same boat as far as wanting to complete a job as swiftly as possible: contractors go on to their next job and homeowners can return to peace in their home. This is prime territory for either party to suggest the work be completed today and the contract or change order executed tomorrow, or even later. However, without a contract, there is no memorialization of the communication between the parties, which can lead to confusion and missed expectations on both sides. Construction plans are rarely as neat and tidy as they originally seem to be. A contractor may uncover unforeseen conditions, an owner may request additional work or changes that require additional work, or weather interferes with project schedules or the work itself. Unfortunately, the signature that never gets collected can become one of the most expensive omissions on a project – for both sides. Read the full story...

Introducing the Updated 2026 Pillsbury Guide to Data Centers

June 08, 2026 — Gravel2Gavel Team - Gravel2Gavel Construction & Real Estate Law Blog
Since the initial publication of the Pillsbury Guide to Data Centers in 2025, the market has continued to evolve—most notably with respect to power availability, energy strategy, tax and incentives planning, and investment activity across the sector. While many of the legal, commercial and regulatory frameworks addressed in the original Guide remain durable and relevant, recent developments warranted targeted updates and additions. The 2026 edition expands and updates our energy-focused content to reflect the increasingly central role of power procurement, interconnection and long-term energy strategy in data center development. We have incorporated new materials addressing power purchase and interconnection agreements, solar and other renewable energy solutions, advanced reactor designs, and nuclear-powered data centers projects, including an updated project tracker. We have also added new analysis covering state and local tax considerations and incentive structures relevant to data center development and operations, as well as current M&A and private equity trends shaping investment in the sector.

Urban Digital Twins: How Virtual Cities Could Help Build Smarter Cities

August 11, 2026 — Gravel2Gavel Construction & Real Estate Law Blog
Traffic congestion, endless construction, flooded streets and power outages. For city leaders and residents alike, these disruptions are simply part of daily urban life. But an emerging tool, known as the urban digital twin, could help cities anticipate problems before they occur by allowing planners to simulate responses, stress-test infrastructure, and evaluate decisions before implementing them in the real world. What Is an Urban Digital Twin? An urban digital twin is a dynamic, data-driven virtual model of a real city. It uses AI analytics and combines 3D modeling with real-time data and information from sources such as IoT sensors, traffic cameras, satellite feeds, infrastructure databases, utility networks, and environmental data including weather systems and heat maps to create a continuously updated digital representation of the urban environment that mirrors infrastructure, movement and systems in real time. In other words, it is a living digital replica of a city. Read the full story...
