### The tabs in this worksheet show 1) projected ozone design values (DVs) from the 2025 base and twelve 2025 emissions sensitivity simulations described in chapter 3 of the RIA and 2) emissions summaries that were used in the calculation of DVs for the scenarios of meeting various standard levels also described in chapter 3 of the RIA Anyone interestsed in these date should first read Chapter 3 of the RIA to fully understand how they were developed and applied in the RIA ozone DV projections were computing using version 2.6.1 of the Model Attainment Test Software (MATS) released on 12/1/14 and available at http://www.epa.gov/ttn/scram/modelingapps_mats.htm Details of how the ozone attainment test was run are given in chapter 3 of the RIA Missing DVs are indicated by a value of -9. Reaseons for missing DVs are explained in more detail in chapter 3 and appendix 3-A of the RIA Application of these projected ozone DVs to create the 2025 baseline and alternative standard scenarios are described in chapter 3 and appendix 3-A of the ozone RIA Tables of ozone DVs for the 2025 baseline and alternative standard scenarios are provided in appendix 3-A of the ozone RIA All emissions scenarios are relative to the 2025 base case VOC cuts in emissions sensitivity #2 were modeled nationwide. However, as described in Chapter 3 of the RIA all VOC impacts were assumed to occur from local emissions changes. VOC buffer regions shown in the other two tabs were used define local impacts regions for 8 areas of the US. Names in the "VOC buffer region" columns of the "2025 ozone DVs" workbook show which VOC buffer each monitor is located in (blank values indicate the monitor is not in one of the buffer regions applied in this analysis)
