EPA Expands PFAS Reporting Requirements with Addition of New Chemical to Toxics Release Inventory, Published by Law360

June 08, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) addition of sodium perfluorohexanesulfonate (PFHxS-Na) to the Toxics Release Inventory (TRI) introduces new federal reporting requirements for businesses that manufacture, process, or use the chemical. Because reporting obligations apply retroactively to the start of the year, affected facilities must quickly evaluate their compliance and recordkeeping practices. In a recent Law360 article, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, explains why PFHxS-Na was automatically added to the TRI, how the EPA’s public reporting system works, and which businesses may be affected by the new rule. The article also touches upon key compliance considerations, including supply chain reviews, reporting thresholds for chemicals of special concern, and preparation for public disclosure requirements.

From Dark Data to Building Intelligence

July 13, 2026 — Aarni Heiskanen - AEC Business
In this episode, I talk with Mark Sorsa-Leslie, founder and CEO of Auttaa AI, whose team just won first place in Luotea’s inaugural hackathon in Helsinki for turning property maintenance from reactive firefighting into proactive forecasting with AI. Mark is a chartered surveyor with 30 years of real estate data experience, previously the founder of the UK sensor company Beringar. We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property. Mark explains how Auttaa bridges real-time building data with large language models, using what he calls an “influence graph” to surface correlations and causation across previously disconnected systems, such as linking occupancy patterns to CO2 readings to diagnose ventilation problems in minutes rather than days.

In the Eye of the Beholder: Court of Appeal Finds Duty of Care Owed by Owner and Contractors for Death of Minors Caused by Independent Truck Driver

May 05, 2026 — Garret D. Murai - California Construction Law Blog
I was a T.A. for my high school history teacher, a really smart and nice guy, Mr. Reynolds. In the room at the back of the classroom which served as his office he had the picture above. It’s called “My Wife and My Mother-in-Law” and is taken from a German postcard from 1888. Depending on how you look it, you might see fashionable young lady, or an old lady. Cases can sometimes be like that: You see what you want to see. The next case is also like that. In Lorenzo v. Calex Engineering, Inc., 110 Cal.App.5th 49 (2025), the 2nd District Court of Appeals reversed a motion for summary judgment granted in favor of an owner and its contractors in a case involving the death of two minors struck by a dump truck enroute to a non-permitted off-site staging area.

Colorado Court Affirms Attorneys’ Fee Award Against Plaintiff’s Counsel for Pursuing Unsupported CCPA Claims

August 03, 2026 — David McLain - Colorado Construction Litigation Blog
The Colorado Court of Appeals recently affirmed a trial court’s award of more than $241,000 in attorney fees against a plaintiffs’ attorney who continued to pursue unsupported claims arising out of a residential construction dispute. Although the opinion was not selected for official publication under C.A.R. 35(e) and therefore has no precedential value, it nevertheless provides an instructive reminder that Colorado courts are willing to impose significant financial consequences when claims lack substantial justification. For builders, developers, contractors, insurers, and defense counsel, the case is worth reading, not because it announces new law, but because it demonstrates that Colorado’s fee-shifting statute remains a meaningful tool when unsupported claims continue long after they should have been abandoned.
