"Federal regulators on Thursday finalized new guidelines to reduce emissions of ozone-forming pollutants for oil and gas drilling sites.

The Environmental Protection Agency’s (EPA) new guidelines are nonbinding. But they’re designed to help states that have not met federal ozone limits, laying out ways for those states to reduce ozone-causing volatile organic compound (VOC) emissions from oil and gas sites.  

The regulations are part of an Obama administration strategy to reduce emissions of methane, a potent greenhouse gas with 25 times the global warming potential of carbon dioxide. "
