Representative Cases :

For four years, he was lead counsel on Crowell & Moring’s team which represented one of the nuclear reactor operating contractors at the Hanford Nuclear Reservation litigation. This consisted of five consolidated class actions, plus individual cases, in which the defense team won significant victories at the motion to dismiss and summary judgment stage before they persuaded the U.S.Department of Energy to take over the defense.

He was lead counsel for the plaintiff City of Delray Beach, Florida, in a groundwater contamination case which, after a four-week jury trial, produced a verdict for the City of $8.7 million, covering past and expected future cleanup costs.

For 5 years he has served as a facilitator in a nationwide civil enforcement case brought by EPA and the Justice Department against a large pipe manufacturer, including 23 facilities and 6 different federal environmental laws and their state counterparts.  This has resulted in a global settlement agreement between the parties, embodied in a federal consent decree.

He served as mediator/arbitrator in a dispute between the purchaser and seller of a large paper mill involving significant Clean Air Act notices of violation, including remedial measures, costs and penalties.
