Green groups press Interior and EPA on methane emissions

More than 90 green groups across the U.S. are calling on the Environmental Protection Agency and Interior Department to regulate methane emissions from oil and gas industry operations.

"EPA needs to take immediate steps to produce regulations to directly reduce methane pollution from new and existing equipment from this industry," the groups wrote in a letter to Interior Secretary Sally JewellSarah (Sally) Margaret JewellZinke and his wife took security detail on vacation to Turkey, Greece: report Zinke: I never took a private jet anywhere Ex-Interior chief ribs Zinke over ‘secretarial flag’ MORE and EPA chief Gina McCarthyRegina (Gina) McCarthyPruitt says he's ‘dumbfounded’ by ‘media narratives’ on travel costs Overnight Energy: EPA plans to restrict use of science data for regs | Pruitt's Italy trip cost more than K | Perry insists he's staying at Energy Cost of Pruitt's Italy trip rises above ,000 MORE on Thursday.

The groups include the Clean Air Task Force, Center for Biological Diversity, and National Wildlife Federation.

They go on to say that without firm controls on methane, the nation will not reach the targets laid out by the Obama administration to slash greenhouse gas emissions by 2020.

The Interior Department must also revise its rules on air pollution from offshore oil and gas sources to accommodate a "fragile" Arctic environment, the letter adds.
