North Dakota is the first state to sue the Environmental Protection Agency over new methane emission rules for the oil and gas industry.
The state, which will be significantly affected by the new rules because of its large shale oil operations, filed its lawsuit Monday in the D.C. Circuit Court of Appeals, arguing that the new rule is "arbitrary, capricious, an abuse of discretion and not in accordance with law."
The methane rule was made in May, requiring shale oil and gas producers to reduce methane leaks at new and modified drilling sites. The rule is part of President Obama's climate change agenda, which seeks to reduce methane emissions 40-45 percent by 2025.
Methane is 25 times more harmful to the Earth's climate than more prevalent greenhouse gas emissions such as carbon dioxide, although it is short-lived. The gases are blamed by scientists for driving manmade climate change.
On Friday, the agency issued final rules for reducing methane emissions at landfills, marking a continued final-year push to implement all regulations related to Obama's climate change agenda.
