SB 4, a bill to require permits for fracking as well as public disclosure of fracking fluid, passed the California Assembly on September 1, with the Senate passing the bill later that day. Prior to Senate approval, a spokesperson for Governor Jerry Brown (D) said that he plans to sign the bill if it passes the Senate again. The Senate approved the measure in May but had to vote on it again because added amendments streamlined the permitting process. Several environmental groups have withdrawn support of the bill because of the amendments.
