Mac Lacy

Senior Attorney

Mac joined ONDA in September 2001 as staff attorney, having served as a student law clerk for the organization beginning in 1999. Since then, he has litigated more than 30 federal court cases and scores of administrative actions for ONDA, helping ONDA to win or successfully settle more than 85% of those legal actions.

Mac's cases focus on wilderness, grazing and ORV issues on eastern Oregon's public lands. Mac has litigated under the Wilderness Act, National Environmental Policy Act, Federal Land Policy and Management Act, Steens Mountain Cooperative Management and Protection Act, National Forest Management Act, Taylor Grazing Act, Endangered Species Act, Wild and Scenic Rivers Act and other federal environmental laws. He also handles ONDA's Freedom of Information Act (FOIA) litigation.

Mac has been an invited speaker on environmental law and public interest litigation issues at a number of continuing legal education programs and seminars. He also has won awards for published articles addressing water pollution from grazing under the Clean Water Act; advocating for a comprehensive public lands soil protection law; and controlling water spreading with Bureau of Reclamation water via the Endangered Species Act in order to protect threatened and endangered fish species.

In his Masters thesis, Mac explored the late Quaternary geomorphic and pedologic history of a region of currently stabilized sand dunes in central Wisconsin. He finally made his way west and attended Lewis & Clark Law School for his J.D., graduating in May 2001.
