APPENDIX 7A: ENGINE ERING COST ANALYSIS Overview Chapter 7 describes the engineering cost analysis approach that EPA used in applying to demonstrate attainment of alternative ozone standard levels of 70, 65, and 60 ppb. This Appendix contains more detailed information about the control costs of the known control strategy analyses by control measure as well as sensitivity analyses for the fixed cost approach used to estimate costs for the unknown emissions controls.
7 A .1 Cost of Known Controls in Alt ernative Standards Analyses This section presents costs of known controls for the alternative standards analyses. Costs are in terms of 2011 dollars and include values for all portions of the U.S. that were part of the analyses. However, because all availa ble known controls for California were applied as part of the baseline analysis, no known controls were available for the alternative standards analyses in California so these costs do not include any known control costs for California. Costs for the alter native standard analyses are incremental to the baseline att ainment demonstration. Tables 7 A

- 1 and 7 A

- 2 present the Costs for known controls by measure for the 70ppb alternative standard analysis for NOx and VOC respectively. Tables 7 A

- 3 and 7 A

- 4 present the Costs for known controls by measure for the 65ppb alternative standard analysis, and Tables 7 A

- 5 and 7 A

6 present the costs for known controls by measure for the 60 ppb alternative standard analysis.

### 7 A .2 Alternative Estimates of Costs Associated with Emissions Reductions from Unk nown Controls This section presents alternative estimates of the extrapolated control costs using alternative average cost per ton of emission reductions from unknown controls. The alternative values used are $10,000/ton and $20,000, as well as the $15,000/ton value used as the prim ary estimate in the RIA. Table 7 A

- 7 presents the alternative estimates for the East and W est Regions in 2025, without California, while Table 7 A

### Note, by definition, the lower per ton estimate is 50% less than the upper end estimate, and the range between the extrapolated cost bounds becomes larger as the alternative levels become more stringent and re al ly more heavily on unknown controls. Tables 7 A
