CLOSE Act

This bill, the CLOSE Act (HR 4782), removes a loophole that allowed oil and gas facilities to aggregate emissions from multiple sources when calculating pollution levels under federal law. It requires the EPA to add hydrogen sulfide - a pollutant linked to health harm - directly to the list of hazardous air pollutants within 180 days of the bill becoming law. The EPA must then, within a year, define specific categories of oil and gas wells and other sources that emit hydrogen sulfide. This change directly affects oil and gas operators by subjecting hydrogen sulfide emissions from their facilities to stricter federal pollution controls.
