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.

EPA Steps Back, Arizona Moves Forward

May 12, 2026 — Patrick J. Paul, John Habib & Sukhmani K. Singh - Snell & Wilmer
In a significant development for Arizona’s business community and environmental policymakers, the U.S. Environmental Protection Agency (EPA) has paused its planned reclassification of Maricopa County from “Moderate” to “Serious” ozone nonattainment status pursuant to the Clean Air Act’s National Ambient Air Quality Standards (NAAQS). This decision marks a shift in federal air policy — one that recognizes the unique challenges faced by regions like metro Phoenix, where environmental conditions beyond local control are often key contributors to air quality readings. The EPA’s move follows a series of meetings between EPA Administrator Lee Zeldin, Arizona elected officials, and business and civic leaders, including a recent roundtable in Phoenix convened by U.S. Senator Mark Kelly. In announcing the pause, Zeldin acknowledged the need for flexibility and fairness in the application of Clean Air Act standards, especially when emissions from other states, nations, and natural events significantly influence local air quality.

New York Enacts First-in-the-Nation Statewide Data Center Moratorium

August 03, 2026 — Joshua L. Sturtevant - Sheppard
As of May 2026, nearly 12 gigawatts of data center load requests were in the New York Independent System Operator interconnection queue, with more than two-thirds of capacity requests entering the queue in 2025 alone. On July 14, 2026, in response to concerns over this rapid growth, Governor Kathy Hochul issued Executive Order No. 62 (the “Order”) imposing a temporary moratorium on data centers in New York State. Among the concerns cited in the Order are the cost burden on ratepayers associated with transmission upgrades required to accommodate large loads, potential environmental impacts, and large-scale water use. The moratorium is intended to halt activities while the state government develops a comprehensive legal framework for data center development. While dozens of municipal and county-level moratoriums are in place throughout the U.S., and while the legislatures of several states, including Maine, have proposed moratoriums, the Order is the first statewide moratorium to be enacted nationally.

Arizona Court Enters $323 Million Judgment Against ZOM Living Following Unanimous Jury Verdict

May 26, 2026 — Gray Development Group
PHOENIX, May 19, 2026 /PRNewswire/ -- A Maricopa County court has entered a $323 million compensatory damages judgment in favor of Gray Development Group against ZOM Holding Inc., doing business as ZOM Living, following a 12-day trial, a unanimous jury verdict and post-trial proceedings related to a proposed business transaction. The jury found ZOM liable on claims of breach of contract and breach of the implied covenant of good faith and fair dealing stemming from a proposed joint venture tied to a planned pipeline of luxury multifamily and commercial projects in Phoenix and Scottsdale. The lawsuit centered on a 13-project, $1.4 billion development pipeline originated and planned by Gray Development Group over more than a decade. In 2019, Gray invited Florida-based ZOM to participate in a joint venture involving the completion of five projects, which would have marked ZOM's entry into the Arizona market. According to court findings presented at trial, the companies entered into a mutual confidentiality and non-circumvention agreement before Gray shared extensive sensitive and proprietary information related to the projects, including planning, market analysis, costs, financial data, local business relationships and operational strategies developed by Gray over decades in Arizona. Evidence presented during trial showed that over a 10-month period while under contract, ZOM made hundreds of requests for confidential project and market information before circumventing Gray and pursuing the projects independently, ultimately displacing Gray from projects it spent years planning and developing. ZOM Living, headquartered in Orlando, develops multifamily and senior housing communities across the United States and operates regional offices in Boston, Dallas, Fort Lauderdale, Nashville, Phoenix, and Raleigh. ZOM is owned by Timeless Investments, the Amsterdam-based family office of Dutch businessman Hans van Veggel, which acquired the company in 1997. About Gray Development Group Gray Development Group was founded by architect Bruce Gray in 1991. The Phoenix-based company was the top-ranked multifamily developer in Arizona for more than a decade. The company designed and developed more than 15,000 apartment and condominium units throughout metropolitan Phoenix. Two Gray-designed developments — a Tempe midrise and a San Diego high-rise — received National Apartment Community of the Year awards.
