Carbon Emission Standards for the Power Sector: Workgroup Information Page

Hosted by the ADEQ and the Arkansas Public Service Commission (APSC)

THE CLEAN POWER PLAN HAS BEEN STAYED BY THE U.S. SUPREME COURT. ADEQ AND APSC HAVE SUSPENEDED CLEAN POWER PLAN WORK GROUP MEETINGS DURING THE STAY.

On August 3, 2015, the U.S. Environmental Protection Agency (EPA) released final rules for the New Source Performance Standards (NSPS) for new power plants as well as carbon dioxide emission standards for existing power plants—commonly referred to as the Clean Power Plan. EPA also proposed model plans as well as a federal plan that would be implemented if a state or states fail to submit an approvable State plan to comply with the carbon emission standards for existing power plants. The proposed federal plan and model plans were published in the Federal Register on October 23, 2015. On December 19, 2016, EPA announced that it is withdrawing the model plans from interagency review and released working drafts of the model trading rules to the public, stakeholders, and states.

ADEQ and APSC met with interested parties (stakeholders) to discuss the final carbon dioxide emission standards for existing power plants, study the efficacy and economic impacts of potential carbon reduction measures from the power sector, and develop a state strategy for Arkansas. On February 9, 2016, the Supreme Court issued an order staying EPA’s Clean Power Plan. The Agencies will not implement a state plan to comply with the Clean Power Plan during the stay; however, the Agencies, in consultation with stakeholders, will continue to evaluate the impacts of potential environmental and energy policies in the State.
