Holland & Hart LLP announced today that David Chung has joined the firm as a partner in its Washington, DC office, further strengthening the firm's Environmental and Natural Resources practice and expanding its capabilities in environmental litigation, regulatory advocacy, and enforcement defense.
Chung joins Holland & Hart from Crowell & Moring, where he co-chaired the firm's Environmental group. He represents companies, national trade associations, and industry coalitions in complex environmental litigation, enforcement matters, rulemakings, and other administrative proceedings. His practice spans most major federal environmental statutes, including the Clean Water Act (CWA), Toxic Substances Control Act (TSCA), National Environmental Policy Act (NEPA), Clean Air Act (CAA), and Endangered Species Act (ESA). Chung has been recognized in Chambers USA for Environment (District of Columbia) since 2019 and was named a Law360 Environmental MVP in 2025.
An experienced environmental litigator and regulatory strategist, Chung has litigated in federal district courts and courts of appeals across the country and has represented clients before federal agencies including the Environmental Protection Agency, Army Corps of Engineers, Department of Agriculture, Department of Energy, Department of the Interior, Consumer Product Safety Commission, and Surface Transportation Board.
"David is one of the most respected environmental litigators and regulatory strategists in Washington, and his decision to join Holland & Hart is a significant addition to our national platform," said Emily Schilling, Practice Group Leader of Holland & Hart's Environmental and Natural Resources group. "His experience representing national trade associations and industry coalitions, particularly on matters involving TSCA, PFAS, water quality, and federal rulemakings, complements and elevates the work we already do for clients across the energy, mining, agriculture, and manufacturing sectors. With David on the team, we can pair deep regulatory and litigation capabilities in Washington with our dedicated on-the-ground knowledge of the industries and landscapes where our clients operate."
Chung advises clients on regulatory strategy, compliance, and federal rulemakings and policy changes. He currently advises the Waters Advocacy Coalition—a multi-industry coalition of national trade associations—on regulatory, legislative, and litigation developments involving the geographic scope of federal authority under the Clean Water Act. He also counsels numerous trade associations and industry groups on chemical regulation, water quality, nutrient management, pesticide regulation, and emerging contaminants.
"David is exactly the kind of lawyer we've been looking to add as we continue to grow our Washington, DC office into a hub for clients facing high-stakes environmental and regulatory challenges with national implications," said Kelly Johnson, Administrative Partner of Holland & Hart's Washington, DC office. "His experience before federal agencies and courts—combined with the relationships and credibility he's built over two decades—will be a tremendous asset to our clients. And with access to our bipartisan federal affairs team, David can now offer clients coordinated litigation, regulatory advocacy, and legislative engagement.”
"What excites me about Holland & Hart is the strength and depth of its Environmental and Natural Resources practice," said David Chung. "The firm has a remarkable team of lawyers dedicated to handling environmental and natural resources issues every day, whether it’s in the context of litigation, permitting, land access, compliance counseling, or transactions. That means clients get practical, soup-to-nuts counsel from a multi-disciplinary team that understands their businesses and the legal landscape they're operating in. I'm also excited about what we can accomplish for clients by coordinating substantive legal work with the firm's federal affairs capabilities. When litigation strategy, regulatory advocacy, and legislative engagement are integrated under one roof, clients are better positioned to achieve their objectives. That's the kind of team I’m thrilled to be part of, and I'm ready to get to work."
