End of an (Endangerment) Era

February 23, 2026 — Sukhmani K. Singh, Christopher P. Colyer & Sean M. Sherlock - Snell & Wilmer
On February 12, 2026, the U.S. Environmental Protection Agency (EPA) announced the repeal of the 2009 Greenhouse Gas (GHG) Endangerment Finding and the elimination of all federal GHG emission standards for motor vehicles and engines.1 The EPA characterized the action as the “single largest deregulatory action in U.S. history.”2 This development marks a fundamental shift in federal climate policy under the Clean Air Act (CAA) and is expected to trigger immediate and extensive litigation. In Massachusetts v. EPA, the U.S. Supreme Court held that GHGs qualify as “air pollutants” under the CAA and that the EPA must determine whether emissions from new motor vehicles cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare under CAA Section 202(a).3 Following this decision, on December 7, 2009, the EPA issued two findings. First, the EPA classified six different GHGs as threatening public health and welfare. Second, the EPA determined that emissions from new motor vehicles contribute to that endangerment.4 Although the findings themselves imposed no direct regulatory requirements, they served as the legal predicate for GHG emission standards for light-duty and heavy-duty vehicles, and later for other CAA programs affecting statutory sources. In 2012, the U.S. Circuit Court of Appeals for the District of Columbia upheld the Endangerment Finding and related regulations.5 Reprinted courtesy of Sukhmani K.

A Permitting Base Checklist for Data Centers and Power Plants

June 02, 2026 — Michael S. McDonough, Stephen J. Humes & Stacey C. Wright - Gravel2Gavel Construction & Real Estate Law Blog
There is a lot of talk these days about “license to operate” for data centers, meaning management of the relationships with stakeholders and broader communities concerning both the benefits and adverse consequences of locating a facility in a particular locale. Here, we are speaking of “license to operate” more literally—namely, the legal and regulatory permitting and approval requirements for a privately owned data center whether by itself or colocated with a power generating plant. Our Base Checklist includes generally and potentially applicable permitting requirements for development and operation, using California as an example. (Taking legal authority Frank Sinatra out of context, “If you can make it there, you can make it anywhere.”) The actual requirements for a given facility would depend, in part, on local law, including planning and zoning laws and plans, and the environment of the site. Just as examples, additional permitting and mitigation requirements might apply if sensitive receptors are located nearby (e.g., noise mitigation for residential dwellings), if sensitive and protected biological resources (e.g., jurisdictional waters and/or protected species) would be impacted, or if the present or former land uses require additional measures (e.g., hazardous materials remediation, mitigation for conversion of prime farmland, or protection of cultural resources). The scope of permit requirements would ultimately be determined by the applicable regulatory agencies and by the lead and responsible agencies under the applicable state environmental land use regime—in our reference case here, the California Environmental Quality Act (CEQA).

Ninth Circuit Holds That Policies Covering Environmental Claims Do Not Have Aggregate Limits

May 12, 2026 — Lorelie S. Masters & Joseph T. Niczky - Hunton Insurance Recovery Blog
In the case of County of San Bernardino v. Insurance Company of the State of Pennsylvania, the Ninth Circuit recently addressed the issue of whether general liability policies issued in the 1960s and 1970s included aggregate limits for claims arising under the premises-operations coverage in CGL policies. The difference between the policyholder’s interpretation of the policies’ limits clauses and the insurer’s interpretation was worth hundreds of millions of dollars in exposure for the insurer. The Court closely examined the policy language and extrinsic evidence from both the insurance industry’s drafting history and the parties before concluding that the policies were ambiguous. The Court construed that ambiguity in favor of the policyholder and ruled that aggregate limits did not apply to the claims at issue. The Court’s decision underscores the importance of carefully examining a policy’s limits, especially for older policies written before 1986 when the insurance industry revised the standard-form CGL policy to state the aggregate limits apply not only to products liability claims but to premises-operations claims as well. Decades of insurance industry drafting history confirms, as the policyholder’s submissions in this case indicate, that the industry well understood that operations claims like the environmental waste-disposal claims at issue here typically were not subject to aggregate limits.

Pay-If-Paid: What You Need to Know Before Signing on the Dotted Line

August 03, 2026 — Christian Fernandez & Matthew Racioppo - Snell & Wilmer
Buried deep in the fine print of a subcontract, a pay-if-paid clause may be looming. If you are a subcontractor or supplier, misreading these clauses can put your cash flow at risk. If you are an owner or general contractor, drafting them incorrectly can leave you with obligations you never intended — or unenforceable protections you were counting on. It is more important than ever to understand when pay-if-paid clauses hold up and when they do not, as well as recent litigation and drafting trends. Whether you are negotiating a new agreement, reviewing your standard form contracts, or staring down a payment dispute, understanding how Arizona law treats pay-if-paid clauses is essential. In this article, we break down key considerations, walk through the legal standards Arizona courts apply, and offer practical tips to consider to help you protect your payment rights on the next project.

Managing Tariff Volatility in Cross‑Border U.S. Construction Projects: Practical Contract‑Drafting and Procurement Strategies

March 10, 2026 — Sara Beiro Farabow & Michael Wagner - The Construction Seyt
Volatile U.S. tariff announcements continue to affect international supply chains for U.S. construction projects. Although recent litigation has centered on the scope of presidential tariff authority rather than construction‑specific disputes, these decisions carry important implications for how parties structure risk in their contracts. In May 2025, the U.S. Court of International Trade (CIT) struck down certain “Liberation Day” tariffs as exceeding presidential authority under IEEPA. A federal district court in Washington, D.C. likewise issued a preliminary injunction suspending related tariffs—though it later stayed its own order pending appeal. And the Supreme Court has agreed to review cases addressing the legal limits of IEEPA‑based tariffs. While none of these developments arises from construction disputes, the themes they highlight—timing, statutory authority, and documentation—mirror the issues encountered when tariff conditions disrupt international procurement. The following strategies reflect practical steps U.S. project owners, contractors, and foreign suppliers can take to mitigate risk, drawing on drafting approaches now widely used across major construction forms, including—but not limited to—modified AIA agreements.

The GKN Aerospace Chemical Release and the Laws Designed to Address It

July 06, 2026 — Sean M. Sherlock - Snell & Wilmer
On May 21, 2026, a 34,000-gallon storage tank at the GKN Aerospace facility in Garden Grove, California began leaking methyl methacrylate (MMA), a volatile and highly flammable industrial chemical used to manufacture high-strength acrylic plastics. GKN Aerospace makes advanced military and commercial transparencies, such as aircraft canopies, windshields, cabin windows, bullet-resistant glass, and spacecraft windows. In polymer chemistry lingo, MMA is known as a monomer. Monomers are like individual links to a chain. Under the right conditions they link up (react) with each other to form long-chained polymers, or plastics. MMA is an unstable monomer that requires controlled storage conditions to avoid setting off a polymerization (chain) reaction. According to early reports, the MMA tank at GKN Aerospace overheated. The cause of the overheating is not yet clear, but the overheating may have created conditions enabling the MMA to initiate polymerization, which in turn generated heat, which in turn generated pressure, activating the tank’s pressure-relief system and releasing MMA vapor into the atmosphere. Concerns about a runaway reaction, massive release, and explosion led the Orange County Fire Authority to order evacuation of approximately 40,000 residents and closure of thirteen schools.
