In California, environmentalists filed a lawsuit against the state itself, alleging regulators did not adequately ensure that companies responsible for hydraulic fracturing followed environmental laws. The lawsuit, which was filed by five environmental groups, alleges the California Division of Oil, Gas and Geothermal Resources did not require companies involved in fracking to complete an environmental impact report. According to the lawsuit, this is a violation of the California Environmental Quality Act, which requires organizations involved in major construction projects to analyze and asses the effects of their project on the environment and how they will lessen any negative effects.
According to the Los Angeles Times (12/05/12), California does not have any regulations requiring hydraulic fracturing companies to report the chemicals they inject into the rock or where fracking occurs.

Regulators in California have agreed to draft regulations to oversee fracking, but it is not yet clear how tightly they will regulate the procedure. California could become the next major site for hydraulic fracturing. According to a report by the U.S. Energy Information Administration (EIA), the Monterey/Santos formation in California is estimated to hold 15.4 billion barrels of shale oil, or 64 percent of total shale oil resources. The next largest have just over 3 billion barrels of shale oil.
As the number of fracking sites increases, so will concerns about the effects of fracking on the environment, the water and residents' health.
