Diablo Canyon, 1973

Construction of the Diablo Canyon Nuclear Power Plant in San Luis Obispo County on January 15, 1973. Pacific Gas & Electric Company went through six years of hearings, referenda and litigation to have the Diablo Canyon plant approved. A principal concern about the plant is whether it can be sufficiently earthquake-proof. The site was deemed safe when construction started in 1968. Unit One was commissioned on May 7, 1985 and Unit Two on March 13, 1986. (Monterey County Herald Archives)
