Controlling Power Plants: The Co-Pollutant Implications Of Epa's Clean Air Act § 111(D) Options For Greenhouse Gases, Alice Kaswan

Alice Kaswan

Existing power plants are the nation’s largest single source of carbon emissions. In the absence of comprehensive federal climate change, EPA is forging ahead with power plant controls through § 111(d) of the Clean Air Act. This article focuses on one critical consideration: the ancillary impacts of carbon controls on associated co-pollutants, like sulfur oxides, particulates, nitrogen oxides, and mercury. The article focuses on an array of regulatory options, including both “inside-the-fence” reductions at power plants and “outside-the-fence” measures that reduce power sector emissions, like renewable energy and consumer energy efficiency. The article then evaluates the co-pollutant consequences of several …

Climate Change, The Clean Air Act, And Industrial Pollution, Alice Kaswan

Alice Kaswan

EPA has braved controversy by applying the Clean Air Act (CAA) to greenhouse gas (GHG) emissions from stationary sources, including utilities and industry. Because GHG controls inevitably affect combustion, they will impact traditional pollutants (termed “co-pollutants”). The Article first argues, as a threshold matter, that co-pollutant consequences are relevant to climate policy choices, and that considering those consequences will lead to improved environmental, administrative, and economic outcomes. It then reviews the CAA’s stationary source provisions and EPA’s implementation of them to date, discussing both the CAA’s potential and its limitations.

Moving beyond the CAA on its own terms, the Article …
