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.

Unable To Afford an Appellate Bond? You May Be “Indigent” And Qualify for a Discretionary Waiver or Reduction of the Bond Amount.

October 26, 2026 — Suzanne M. Nicholson - Wilke Fleury
One of the most frequent questions asked when a client is considering taking an appeal from an adverse judgment or order is whether that judgment or order is stayed pending appeal. The answer, not surprisingly, is “it depends.” While the general rule is that perfecting an appeal stays proceedings in the trial court, including enforcement of the judgment or order, there are many, many, exceptions to that rule. One such exception is a judgment or order for “money or the payment of money.” (CCP § 917.1) In such cases, a bond or undertaking is typically required to stay enforcement. The costs of such security can be significant. If you are using an admitted surety insurer, the amount of security required is 1 1/2 times the amount of the judgment. Obtaining a bond through an admitted surety will require that you have sufficient collateral to secure the bond, and sufficient funds to pay the associated premiums, which generally run between 1% and 3% of the total bond amount, per year. So, if you are appealing from a $1 million judgment, you will likely need $1.5 million in assets as collateral, and up to $30,000 per year for the premium. Read the full story...

California Contractors Get a Much-Needed Break: SB 342 Softens the Harsh Consequences of Contractor License Lapses

October 20, 2026 — Heather Frisch - The Construction Seyt
Imagine completing a multimillion-dollar project, performing quality work, paying your subcontractors, and satisfying the owner, only to discover that a temporary contractor license lapse could prevent you from recovering payment for that work or pursuing claims for extra work. For decades, that was the reality under California Business and Professions Code section 7031. A contractor that allowed its license to lapse, even briefly, could face catastrophic consequences completely disconnected from the quality of its work. In some cases, a contractor that performed otherwise flawless work could be barred from recovering payment and even be ordered to disgorge compensation already received – even if the owner knew the contractor had a lapse in its licensing and allowed it to continue construction. That reality is about to change. Read the full story...

Insured’s Failure to Determine Depreciation When Presenting Claim for Replacement Cost Value

August 16, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The Third Circuit affirmed the district court’s granting of summary judgment to the insurer when the insured submitted replacement cost value of the loss but did not include a determination of depreciation. Kimmel v. Massachusetts Bay Ins. Co., 2026 U.S. App. LEXIS 16569 (3d Cir. June 9, 2026). A lightning strike downed a tree on the insured’s property, causing extensive damage to the home. The insured had a homeowner’s policy with Massachusetts Bay Insurance Company (MBIC). MBIC denied the claim, determining that much of the claimed damage already existed and that several policy exclusions otherwise barred coverage. The insured filed suit for breach of contract and bad faith. Read the full story...
