The Environmental Protection Agency is set to soon announce a two-year delay of an Obama-era rule setting new standards for methane, a potent greenhouse gas, from oil and gas wells not yet drilled, according to an EPA official and public filings.

Driving the news: The White House recently completed its review of a proposal that stays the rule, which President Obama's EPA finalized in May 2016. A senior EPA official told Axios Tuesday the goal was to release the proposal next week, and that it's unlikely to be released this week.
