Protesters gather and hold signs before a hearing on proposed rules for hydraulic fracturing, or fracking, oil and gas drilling in Raleigh, N.C. on Wednesday Aug. 20, 2014. The public comment period lasts until Sept. 30. In June, Gov. Pat McCrory signed a law clearing the way for permits to be issued for hydraulic fracturing _ or fracking _ as soon as next spring.
