The Obama administration's newly proposed fracking rules have a major limitation: They only apply to a sliver of the nation's natural gas-drilling lands.
ProPublica's Lena Groger reports that the proposed federal rules only apply to U.S. Bureau of Land Management and Indian lands, not to U.S. Forest Service, private or state-owned lands.
The land to be covered by the proposed rules make up 11 percent of the country's natural gas supply and 5 percent of its oil supply, she wrote.
