The Obama administration said Friday it will for the first time require companies drilling for oil and natural gas on public and Indian lands to publicly disclose chemicals used in hydraulic fracturing operations. The proposed "fracking" rules also set standards for proper construction of wells and wastewater disposal. (AP Photo/Keith Srakocic, File)
