"LOS ANGELES - California’s attorney general on Wednesday said the state plans to sue the Trump administration over its repeal of Obama-era rules meant to address public safety concerns in hydraulic fracturing, or fracking, on federal lands.

The suit, which Attorney General Xavier Becerra said would be filed on Wednesday, marks the latest in a string of court challenges by California against the administration of Republican U.S. President Donald Trump’s policies on a range of issues from immigration to the environment.

The federal government’s Bureau of Land Management (BLM) in 2015, under Democratic President Barack Obama, issued rules that would have required companies to provide data on chemicals used in fracking and to take steps to prevent leakage from oil and gas wells on federally-owned land."
