The Assembly has approved a bill that could lead to a new low-level nuclear waste site in California. Bill author Fred Keeley says California needs to fulfill an obligation the state made when it signed a compact with Arizona, North Dakota and South Dakota to find a site for low-level nuclear waste. That agreement was ratified by the Legislature in 1987. The disposal site would store waste from hospitals and nuclear laboratories. Opponents fear contaminated water might leak into surrounding soils. The bill now goes to the Senate.
