In a letter dated April 18, 2017, the U.S. Environmental Protection Agency (EPA) announced that it would convene a process for reconsideration of the fugitive emission requirements at well sites and compressor station sites in the New Source Performance Standards for the Oil and Gas Sector (which cover methane emissions as well as VOCs). The letter was sent to fossil fuel companies such as the American Petroleum Institute who had requested reconsideration of the rule.
