FERC Order 1000 creates an opportunity for air regulators to ensure that regional transmission planning processes support and do not exacerbate efforts to attain national ambient air quality standards. In this presentation at the Air and Waste Management Association’s Climate Change conference, Dave Lamont describes opportunities for air regulators to proactively work with their public utility counterparts to advance public policy objectives such as clean air, energy efficiency, and renewable energy initiatives, which help to alleviate air pollution emissions. Air regulators can also participate directly in regional transmission planning processes as stakeholders and ensure that pollutant costs are included in cost-benefit analyses.
