He has tried jury and non-jury cases in federal and state courts.

For over 20 years he has assisted companies in the design and implementation of corporate environmental, health and safety auditing and compliance programs. He has worked extensively with companies in conducting environmental audits, planning for future growth, handling environmental aspects of acquisitions and other business transactions, and setting up training programs.

Representative Cases :

For the past 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.

During 2000-04, Ridge served as court-appointed Monitor to oversee the design and implementation of a nationwide Environmental Management System by BP Amoco at all of its oil exploration, drilling and production facilities, on-shore and off-shore.

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.

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 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 DOE to take over the defense.

In 1998 he won a three-week jury trial of a False Claims Act case involving alleged Clean Water Act violations, which was affirmed by the Sixth Circuit.


Speaking and Teaching :

Ridge has spoken widely on all aspects of environmental law, regulation and litigation on programs sponsored by the American Bar Association, the International Bar Association, the American Law Institute, Government Institutes, Federal Publications, Executive Enterprises, the Environmental Law Institute, and numerous industry groups, trade associations and other organizations.

From 1978 through 1996 he and Tom Truitt taught the popular 3-day intensive course on “Practical Environmental Law” for Federal Publications twice a year. For many years he also taught Federal Publications courses on “Environmental Auditing and Compliance Assurance” and “Hazardous Waste Litigation and Dispute Resolution”.  For nearly 20 years he and his colleagues at Crowell & Moring taught the Government Institutes intensive courses on the Superfund law and the Hazardous Waste regulatory program.  For a decade and a half, through 2008, he co-chaired the ALI-ABA Conference on Hazardous Substances, Site Remediation and Enforcement.
