State air official John Paul pitches 'plan B' on mercury emission regulations
New rules from the U.S. EPA require power plant operators to reduce mercury emissions 70 percent by 2018, but some state regulators want to take those mercury regulations a step further. John Paul, head of the Dayton, Ohio, regional air pollution office, explains a new plan from state officials to make even larger reductions in mercury emissions. But can existing technology help meet these tougher standards? Will these state rules drive up energy costs for consumers? Paul, president of the Association of Local Air Pollution Control Officials, tackles these questions and more.
