1. 2018 CO 2 Emission Projections for the SESARM States Prepared by: Byeong-Uk Kim, Jim Boylan, and Keith Bentley GA EPD – Air Protection Branch October 22, 2013

2. Background The President’s climate action plan in June 2013 reiterated his 2009 goal of a 17% reduction in CO2 emissions by 2020 from a 2005 baseline. EGU emissions trending downward due to: – Lower natural gas prices – Closure of older inefficient units – Compliance with CAIR and MATS – Compliance with state rules – Increases in renewable energy and nuclear EPA seeking state input on how 111(d) requirements should be implemented Need reference point as starting point for discussions 2

3. Approach Extracted 2018 heat input values by fuel type (coal, oil, gas) from ERTAC EGU projection tool. – 2011 CAMD heat input data was used as the starting point for the projections – Applied ERTAC growth factors by fuel type from the AEO 2013 Report – Applied emission controls submitted by the states Applied CO2 emission factors (TPY CO2/MMBTU) to projected 2018 heat inputs for each fuel type. – State specific CO2 emission factors (EFs) derived from 2005 CAMD data for coal, oil, and gas – National CO2 emission factors for coal, oil, and gas Compared 2005 and 2011 CO2 emissions with 2018 projected CO2 emissions. 3

4. Methodology 200520112018 Heat Input (MMBTU) CAMD HI Data ERTAC EGU Projection Tool CO2 Emissions: Method 1 (TPY) CAMD CO2 Data State derived CO2 EFs from 2005 CAMD CO2 Emissions: Method 2 (TPY) CAMD CO2 Data National CO2 EFs -- Coal (0.103) -- Gas (0.058) -- Oil (0.087) CO2 Emissions: Method 3 (TPY) National CO2 EFs -- Coal (0.103) -- Gas (0.058) -- Oil (0.087) National CO2 EFs -- Coal (0.103) -- Gas (0.058) -- Oil (0.087) National CO2 EFs -- Coal (0.103) -- Gas (0.058) -- Oil (0.087) 4

5. State Derived CO2 Emission Factors *Due to 2005 and 2011 CAMD data issues with WV Oil, SEMAP Oil CO2 Emission Factor was based on data from nine states. 5
