Leslie Carothers: Donald Stever is an environmental lawyer with more than 30 years of civil and criminal environmental litigation and counseling experience. He is now a partner at the K&L Gates law firm in New York. In his earlier incarnations, he was chief of not one but two sections--enforcement and environmental defense--at the U.S. Department of Justice. And when he was even younger, in the 1970s, he was the primary, or perhaps the only, environmental lawyer in the Attorney General's Office in New Hampshire. It was during that time that I got to know him when I was enforcement director at the U.S. Environmental Protection Agency (EPA) in Boston. His boss at the time was the recently retired Justice David Souter, who was then the attorney general, and Don claims modest credit for the Justice's relatively friendly decisions on behalf of the environment. So, Don, welcome, and take it away.
