  1. CAIR & MATS 2012 Southern SectionalAWMA Annual Meeting& Technical Conference September 12, 2012 Chris Goodman, P.E. Environmental Strategy

  2. Southern Company Generating Facilities

  3. Environmental Program at a Glance • Through 2011, invested about $8.3 B in environmental controls • 17 FGDs on 25 units • 17 SCRs • 4 baghouses with ACI • Projected base capital environmental expenditures of about $1.5 B over the next 3 years; Projected to spend an estimated $1.8 B for MATS and $0.5 B for ash and water compliance over the next 3 years • Since 1990, emissions of sulfur dioxide • and nitrogen oxides are down over 70 percent, • while electricity generation has increased • by more than 30 percent to serve growing demand

  5. Transport Rules (CAIR/CSAPR) • CSAPR vacated and remanded to EPA August 21 (CAIR remains in place) • Court held that EPA exceeded its CAA authority • CAIR Phase II begins in 2015 • Tighter SO2 and NOx allowance requirements

  6. Mercury and Air Toxics Standards (MATS) • Final rule issued by EPA on February 16, 2012 • Largely unchanged from proposed rule • Some additional compliance flexibilities based on comments • Imposes stringent emission limits for mercury, particulate matter, and acid gases • Could force many retirements and large capital expenditures across the industry • Unreasonable compliance time of three years(April 2015), with case-by-case 1-year extensions

  7. EPA New Regulatory Actions Timeline

  8. CAIR/CSAPR • PM-2.5 NAAQS • 8-Hour Ozone NAAQS • Mercury (Cobenefit) • Regional Haze (BART) • NO2 NAAQS • Utility MACT Coal-Fired Boiler Dust&Hg Control ESP NOx & Hg Control SCR Air Heater New Stack SO2 & Hg (acid gases) Control Scrubber Baghouse (Hg) (Activated Carbon Injection) SNCR NOX Combustion Controls Flyash Gypsum • CAIR/CSAPR • Regional Haze (BART) • Mercury (Cobenefit) • PM-2.5 NAAQS • SO2 NAAQS Bottom Ash Emission Control Technologies for Coal-Fired Boilers CO2 Reduction • GHG Regulation/Legislation • 316(a) Thermal • 316(b) Intake Structures Scrubber WasteWater Physical/Chemical/ Biological Treatment Groundwater Monitoring/ Dry Handling / Landfilling / Pond Closure • Effluent Guidelines Scrubber WasteWater Ultra Fine Filtration Process Water Cooling Tower/ Intake Screens • CCR Rule • Effluent Guidelines

  10. Preliminary Assessment of Impactsof EPA Rules – More to Come Possible Outcome • Install new controls on 13 GWs - 65% of coal fleet. • Retire 3 – 4 GWs of coal-fired generation. • Fuel switching of 3 -4 GWs, primarily to natural gas • Potential Impacts • Estimated $13B - $ 18B capital cost through 2020 • Possible 10% - 20% electricity price increases over the next 10 years

  11. Summary • Cumulative impacts of MATS, CSAPR/CAIR, 316(b), new effluent guidelines, CCBs, NAAQS, GHGs and other requirements must be considered when making decisions • Research, testing and planning are the keys to finding the least cost, least regret, site specific solution • Continuous process and is complicated by uncertain future environmental rules and national energy policies
