Implementing EPA’s Clean Power Plan: A Menu of Options May 2015 Implementing EPA’s Clean Power Plan: A Menu of Options May 2015 Implementing EPA’s Clean Power Plan: A Menu of Options Acknowledgements On behalf of the National Association of Clean Air Agencies (NACAA), we are pleased to provide Implementing EPA’s Clean Power Plan: A Menu of Options. Our association developed this document to help state and local air pollution control agencies identify technologies and policies to reduce greenhouse gases from the power sector. We hope that states and localities, as well as other stakeholders, find this document useful as states prepare their compliance strategies to achieve the carbon dioxide emissions targets set by the EPA’s Clean Power Plan. NACAA would like to thank The Regulatory Assistance Project (RAP) for its invaluable assistance in developing this document. We particularly thank Rich Sedano, Ken Colburn, John Shenot, Brenda Hausauer, and Camille Kadoch. In addition, we recognize the contribution of many others, including Riley Allen (RAP), Xavier Baldwin (Burbank Water and Power [retired]), Dave Farnsworth (RAP), Bruce Hedman (Institute for Industrial Productivity), Chris James (RAP), Jim Lazar (RAP), Carl Linvill (RAP), Alice Napoleon (Synapse), Rebecca Schultz (independent contractor), Anna Sommer (Sommer Energy), Jim Staudt (Andover Technology Partners), and Kenji Takahashi (Synapse). We would also like to thank those involved in the production of this document, including Patti Casey, Cathy Donohue, and Tim Newcomb (Newcomb Studios). We are grateful to Stu Clark (Washington) and Larry Greene (Sacramento, California), co-chairs of NACAA’s Global Warming Committee, under whose guidance this document was prepared. Finally, we appreciate the NACAA staff who oversaw this project, including S. William Becker, Executive Director, Karen Mongoven, Senior Staff Associate, and Phil Assmus, Senior Staff Associate. We also recognize the efforts of the NACAA 111(d) Steering Committee for this project, which included directors and staff from state and/or local air pollution control agencies in the following states: Arizona, California, Colorado, Delaware, Massachusetts, Michigan, Minnesota, Nebraska, New Mexico, South Carolina, Tennessee, Washington, and Wisconsin.
