Summary

Removes a Clean Air Act exemption that limited how emissions from oil and gas sources are counted, and directs the EPA to add hydrogen sulfide (H2S) to the federal list of hazardous air pollutants and regulate the sources that emit it. The EPA must issue a final rule listing H2S within 180 days of enactment and then update the list of source categories (including oil and gas wells) within 365 days after that rule.
