7. Resolution of Outstanding Issues 4 Viability of the Market 4 Audit and Reconciliation 4 Greater Reasonable Progress than BART

8. Milestones - Principles 4 Achieve Steady Continuing Emissions Reductions 4 Provide Flexibility to Sources “Up-Front” for Greater “Back-End” Reductions 4 Policy driven 4 Informed by best available information

9. 2018 Milestone - Revised Basis 4 Baseline emissions projection 622,000 tons –Known reductions –Assumed retirements & tech. changes –New source & utility growth –Operational adjustments 4 Estimated BART reductions-168,000 4 Utility CEM adjustment- 10,000 4 Uncertainty/Headroom+ 35,000 4 Total (rounded to nearest 5,000) 480,000 4 Smelter Set-aside+ 30,000 4 2018 Milestone 510,000

10. SO 2 Milestones 13% Reduction 52% Reduction

11. Compliance with Milestones (hypothetical case)

12. Compliance with Milestones - 2003 thru 2006

13. Compliance with Milestones - 2003 thru 2006 The Mohave Problem Solved Milestone Committed Emissions Reductions

14. Compliance with Milestones - 2003 thru 2006 The Mohave Problem Solved Milestone

15. Compliance with Milestones (hypothetical case) 2013 Avg.Milestone 2014 Avg.Milestone 2 yr average 1 yr Check

16. CEMS Bias 4 Blanket adjustment of milestones would be spurious 4 Protocol to be developed that will revise milestones based upon documented impact of new technology and revised procedures on a source-by-source basis. 4 Adjustment of milestones may require SIP revisions

17. Allocations 4 New Source Set-aside –Estimated 27,000 tons of growth 2003-2018 –9,000 tons per five year period –Available on first-come first-served basis –Unused tons would roll-over to next period –New sources needing to buy credits would be first in line for next five year period

18. Allocations 4 Individual Source Allocations –Actual allocations not necessary - need to submit allocation method –Estimates prepared - See Appendix F –Final determination of individual source floors for non-utilities needed

19. Opt-in/Opt-out 4 Existing source allocations 4 Distribution of set-asides –New source growth based on projections developed by ICF and Pechan-Avanti on a state-by-state geographic area basis –Tribal allocation (See Appendix G)

20. Penalties for Exceeding Allowances 4 $5,000/ton, CPI adjusted from 2000 base year 4 Mitigation - 2 ton credit reduction in allocation for each ton over-emitted

21. Better Reasonable Progress Than BART 4 Provides both remedy for existing and prevention of future impairment. 4 More sources and total tonnage covered. 4 New source growth capped for the region. 4 Mass-based cap on actual emissions. 4 Greater total tonnage reduction. 4 Regional haze visibility improvement not distinguishable from application of BART.

22. Other Issues 4 Audit and Reconciliation –Working with EPA to include in program 4 Viability of Market –Majority of reductions in Colorado, Wyoming & Arizona –Hire contractor to evaluate

23. Continuing Work 4 Allocations 4 Polished Annex for submittal October 2 4 Draft Revisions to §51.309 4 Final resolution of outstanding EPA issues
