The EPA has issued proposed rule changes that would tighten regulations on air emissions from the oil and natural gas industry. They are holding public hearings in Pittsburgh, Denver, and Arlington. The Arlington hearings run all day from 9 a.m. to 8 p.m. (though there is a 12:30-2:00 lunch break and a 5:00-6:30 dinner break). They are seeking public input - so get educated and come and speak!
