Article Photos: Interior issues new drilling rule on public land 1/2

The Obama administration is proposing a rule that would require companies that drill for oil and natural gas on federal lands to publicly disclose chemicals used in hydraulic fracturing operations. The new "fracking" rule replaces a draft proposed last year that was withdrawn amid industry complaints that federal regulation could hinder an ongoing boom in natural gas production.
