An environmental engineer who worked on design and construction of the Valdez Marine Terminal, he then, joined the Alaska Department of Environmental Conservation as one of the first inspectors of terminal and tanker operations.
In 1982, Lawn began warning his DEC superiors that Alyeska could not efficiently respond to a major spill, but he was ignored.
Seven years later, he was the first regulator notified the night the Exxon Valdez ran aground on Bligh Reef. Lawn videoed some of the 11 millions gallons of crude oil rushing to Prince William Sound, as well as Alyseka's inefficient attempts to contain the spill.
For over ten years before the spill, Dan documented the failures of the oil industry to prevent spills and to adequately prepare for clean-ups, and warned the state about the potential for a major disaster in Prince William Sound.
Interviewed numerous times on national television, he is considered a champion among the environmental community in the U.S. and abroad. In the 1994 HBO movie, Dead Ahead, directed by Paul Seed, about the Exxon Valdez spill, Lawn is depicted as the frustrated hero, played by actor John Heard.
