Colorado oil and gas regulators have proposed requirements to increase the minimum distance between homes and drill sites and to mitigate impacts of drilling within 1,000 feet of residences.

The draft rule, issued Monday by the Colorado Oil and Gas Commission, would ban drilling within 500 feet of a home anywhere in the state.

Regulators, the industry and environmental and community groups have wrestled for a year — as drilling has accelerated on the Front Range — over how close to homes wells can be drilled.
