Colorado voters decided Tuesday to reject a measure that would have blocked drilling in most of one of America’s largest oil- and gas-producing states.

Coloradans shot down a ballot initiative banning new oil and gas drilling within 2,500 feet of homes, schools, and “vulnerable areas” such as playgrounds. The measure was intended to respond to complaints from communities close to fracking who say wells are increasingly encroaching on populated areas and played a role in recent deadly explosions and tainted groundwater.
