The state also hopes to include new limits on emissions from dehydrator units near residential areas.
If the rules go into effect, the Colorado Department of Public Health and Environment estimates they would reduce volatile organic compound emissions by about 92,000 tons a year, an amount greater than the emissions from vehicles in Colorado. The department said that reduction would lead to related decreases in asthma cases.
The CDPHE negotiated the new rules with the Environmental Defense Fund and three oil and gas companies, Noble Energy, Encana and Anadarko, that operate wells around the state. The companies said in a joint statement that they support the draft.
“As citizens of Colorado, we all want clean air, and we support this joint proposal initiated by Gov. Hickenlooper,” the companies said. “This collaboration is a good model for developing effective regulations and activities to monitor, control and reduce methane leaks and VOCs.”
A spokeswoman for the American Petroleum Institute said the group hadn’t taken a position on the proposed regulations.
The new rules have to pass muster with the Air Quality Control Commission, which meets on Thursday. A public hearing is likely in February.
Fred Krupp, president of the Environmental Defense Fund, called the rule-making process a “model for the nation. It shows that state officials, industry leaders and environmental groups can come together to develop win-win solutions that help square the need to protect local communities and the environment with the need for domestic energy production.”
Oil and gas industries have found a valuable home in Colorado. The state produced more than 40 million barrels of oil in 2012, according to the state Oil and Gas Conservation Commission, the first time since 1962 they topped the 40-million mark.
