With three decades of experience as an environmental advocate for clients and training as a chemical engineer, John Rego resolves environmental disputes by blending sound scientific positions with practical legal guidance. He has used this pragmatic, fact-driven approach to negotiate and, when necessary, litigate on behalf of companies in the electronics, petroleum, metals, and manufacturing sectors in matters ranging from litigation of natural resource damage claims to settlement of substantial bankruptcy claims to negotiation of federal air emission standards. Because he understands the language of environmental scientists, John is able to advocate for reasonable, risk-based outcomes to environmental challenges.

John's environmental litigation experience encompasses defense of Superfund and Clean Water Act claims, common law "toxic tort" claims, and hazardous waste citizen lawsuits, as well as successful administrative challenges to actions by state and federal agencies. For example, on behalf of Eramet Marietta, John challenged the federal manganese emission standards for ferroalloys production, leading to a settlement in which the U.S. EPA withdrew its standards and adopted those proposed by our client. He also obtained summary judgment against Ohio EPA's challenge to a precedent-setting cleanup under Ohio's Voluntary Action Program. However, John believes that with creativity, diligence, and a sound technical approach, most environmental disputes can be avoided or resolved without costly litigation.

John is the executive editor of Jones Day's quarterly electronic climate change advisory, The Climate Report.
