UPDATE: The Natural Resources Committee held a hearing on it on June 21, and the bill passed on the 23rd.
What is Romero's reasoning, when the state budget is unconstitutionally overdue and the government itself is a notorious joke? She repeats the clueless claim that serpentine is actually deadly asbestos. I believe that she is doing the bidding of asbestos lawyers. Their legitimate work in redressing old injuries from the asbestos industry, unfortunately, entails scaring the public with misleading statements like this 2007 release from attorney Roger Worthington at mesothel.com: "Serpentine commonly contains chrysotile asbestos, a carcinogen listed by the EPA and a mineral that has indiscriminately claimed the lives of tens of thousands of people every year in the United States, and hundreds of thousands of people worldwide." Truth: Some serpentinite contains certain minerals which, in heavy long-term workplace exposure of powdered material, has increased the rate of lung disease in asbestos workers. Chrysotile is not one of these.
Areas of serpentinite in California have restrictions on releasing large quantities of dust. Even that tiny risk is based on statistical arguments rather than medical evidence.
I say to Senator Romero, leave the stone alone.
