After a speech Gofman gave on nuclear waste at a national conference of activists in the summer of 1990, Charles Butler approached him for help. Butler was a retired physicist living in the Mojave Desert town of Needles, California, and was looking for help to stop the proposed low-level nuclear waste facility at Ward Valley. Gofman referred him to the Abalone Alliance Clearinghouse in San Francisco. With less than two weeks before the closure of the Environmental Impact Statement, the Alliance was able to mount a letter writing campaign that helped delay the EIS for an additional 90 days. This initial delay gave activists the time to form Don't Waste California and build a grassroots campaign that eventually stopped Ward Valley from opening.
