Ed McTiernan focuses his practice on state and federal regulatory issues including site remediation, natural resource damages, energy and infrastructure transactions, and environmental permitting aspects of real estate development and redevelopment projects.

In 2011, Mr. McTiernan was appointed to the New York State Department of Environmental Conservation by Governor Andrew Cuomo where he served as Deputy Commissioner and General Counsel. In that capacity, he was responsible for enforcement, rulemaking, and major policy initiatives relating to New York environmental laws, including the review and permitting of major infrastructure and energy projects, as well as the development of an audit policy to encourage voluntary compliance. He supervised a team of 90 attorneys and 30 support staff in the central office and nine regional offices, and coordinated with federal agencies and national and environmental advocacy groups on a number of controversial projects. In addition, he directly supervised the state’s docket of litigation, enforcement proceedings, and policy initiatives.
