Emission Controls and Monitoring

Allowance trading allows sources in cap and trade programs to adopt the most cost-effective strategy to reduce emissions. To meet the Acid Rain Program (ARP) and Clean Air Interstate Rule (CAIR) emission reduction targets, some sources opted to install control technologies. A wide set of controls is available to help reduce emissions. The tracking and reporting of accurate and consistent emissions monitoring data is important to ensure program compliance and is achieved through the use of continuous emission monitoring systems (CEMS). The following is an analysis of controls on ARP and CAIR units.
