The Obama administration announced its first steps on Friday toward possibly tighter regulation of hydraulic fracturing, or fracking, seeking public input on whether companies should be required to disclose the contents of fluids used in the oil and natural gas drilling technique.
The U.S. Environmental Protection Agency said it would gather public comment for 90 days on whether to require chemical manufacturers to disclose the contents of fluids they inject into shale seams to release trapped oil or gas.
