DENVER (AP) - Colorado's oil and gas regulators have approved new rules for reporting oil and chemical spills.
The Colorado Oil and Gas Conservation Commission voted unanimously Tuesday that companies must report any spill of five barrels or more within 24 hours. That's down from 20 barrels.
Drillers must also report a spill of as little as one barrel if it occurs outside of a containment area.
Todd Hartman of the state Department of Natural Resources says the industry used to have as many as 10 days to report a spill.
A barrel contains 42 gallons.
Regulators didn't change an existing requirement that any spill that threatens the state water supply be reported within 24 hours.
