Critics of oil and gas fracking protested Tuesday outside of Colorado Springs City Hall in search of more curbs on hydraulic fracturing, or fracking.
The Springs rally came in advance of Tuesday afternoon's City Council meeting, where officials are were scheduled talk about oil and gas drilling regulations.
Critics say the proposed regulations need more environmental safeguards.
The Springs rally comes three weeks after citizens in Longmont overwhelmingly voted to ban hydraulic fracturing over similar concerns. State officials and the oil and gas industry say local governments can't set their own drilling rules.
The process involves blasting water, sand and chemicals underground to free oil and natural gas.
