Claudia K. Powers

Senior Counsel

Claudia Powers is an environmental and energy lawyer who chairs the Environmental Practice Group at Ater Wynne. Her clients include, among others, international chemical, steel pipe and industrial gases corporations, light and heavy industries, municipalities, electric power producing companies, and a regional water resource management facility that produces fertilizer from waste water.

Claudia is listed in Chambers USA and Best Lawyers in America for her expertise in Environmental Law.  Her background and experience in energy, sustainability, and environmental law makes her one of the most sought after attorneys for complicated superfund, natural resources, and contaminated property redevelopment projects.  Currently, she is working on the redevelopment of industrial property inside the Portland, Oregon Urban Growth Boundary, a project involving public and private cooperation with the Oregon Business Development Department’s Brownfields Program and the Oregon Department of Environmental Quality.  She is also working with public and private parties to redevelop former mill and plywood sites in Southern Oregon and Central Washington.

She is the lead environmental attorney for an international steel pipe manufacturer, assisting the company in acquisitions, cleanup and sales of industrial property as well as regulatory permitting and compliance matters.  Claudia is also a skilled negotiator with broad problem-solving experience.  She negotiated one of the state’s first pre-purchaser agreements for the transfer and cleanup of contaminated property.  She has negotiated a variety of transactions and complex liability allocation agreements.  She headed the environmental strategy team in one of the region’s most unusual bankruptcy cases involving environmental liability.  She has worked extensively with local, state, and federal regulators to successful effect for over 30 years.
