Arnold & Porter

Arnold & Porter regularly advises on the Clean Air Act, Clean Water Act, Oil Pollution Act, and the Endangered Species Act. Across 2024 Stacey Halliday, Brandon Neuschafer, and Jeffrey Talbert joined the experienced team co-chaired by the Washington DC-based duo Jonathan Martel and Allison Rumsey. With prior experience from the EPA, Martel is known by clients for regularly assisting on Clean Air Act regulatory matters, while Rumsey is active in state and federal regulatory enforcement actions and permits for large infrastructure. The DC office is also home to Ethan Shenkman, who has positioned himself as a key advisor on climate change policy and regulations, Lawrence Culleen who advises clients on chemical, pesticide, and antimicrobial regulations, as well as Halliday, formerly at Beveridge & Diamond, P.C., who represents electronics and textile clients on product compliance and global supply chain matters. Air quality is a key pillar of the firm’s practice and on this front, San Francisco-based Zachary Fayne is a key point of contact, as an expert on the Clean Air Act. The deep bench also includes Chicago’s Neuschafer, who joined in 2024 and advises clients on regulatory matters regarding food, agricultural, and chemical products, and Sarah Grey, who is noted for her work on energy transition, decarbonization, and climate change policy and regulation from the Denver office. Brian Israel  departed from the team in August 2024.
