Colorado adopted tougher air pollution rules for the oil and gas industry — the first in the nation to cover methane, a gas linked to climate change.
State air quality control commissioners voted 8-1 on Sunday to pass the rules with the support of leading operators Anadarko Petroleum, Noble Energy and Encana.
But they did so over the protests of much of the oil and gas industry, including the powerful Colorado Oil and Gas Association and Colorado Petroleum Association trade groups.
