The Connecticut Voluntary Agreement (CVA) is a state-level agreement between Connecticut and the United States Environmental Protection Agency (EPA). It is a legally-binding agreement that sets forth limits on emissions from power plants in the state. The CVA sets limits on emissions of nitrogen oxides, sulfur dioxide, mercury, carbon dioxide, and other pollutants from the state’s power plants. It also requires the plants to install modern pollution control technologies and make other improvements to reduce emissions. The CVA applies to electric generating units of 50 megawatts or more in capacity, located in Connecticut. The CVA is divided into three parts: 1) an Emissions Trading Program, 2) a Regional Haze Reduction Program, and 3) a Regional Nitrogen Oxides (NOX) Reduction Program. The Emissions Trading Program allows for the transfer of emissions allowances among power plants in the state, providing an economic incentive for plants to reduce their emissions. The Regional Haze Reduction Program requires power plants to reduce their emissions of sulfur dioxide, nitrogen dioxide, and other pollutants that contribute to regional haze. The Regional NOX Reduction Program requires power plants to reduce their emissions of nitrogen oxides. The CVA is designed to help reduce air pollution in Connecticut and improve public health. It is part of a larger effort to reduce emissions from power plants in the state and comply with federal air pollution regulations.
