<br />2. A 2007 future year modeling emissions inventory will be developed by <br />December 31, 2003. This inventory will sufficiently account for projected future <br />growth in ozone precursor emissions through 2007, particularly from stationary, <br />non-road and on-road mobile sources <br /> <br />3. One further episode inventory will also be developed to represent the variety of <br />situations that typically contribute to ozone production in the area and to include <br />the most recent emissions modeling methods and data. Additional inventories <br />will be contingent upon legislative appropriations or other funding. Selection of <br />specific episode inventories will be partially determined by the conceptual model, <br />which reflects an analysis of meteorological conditions typical of high ozone <br />events. <br />a. The conceptual model will be updated by November 30,2003. <br />b. A schedule for the development of further episode inventories will be <br />completed by January 31, 2004. <br /> <br />4. Emissions inventories will be compared and analyzed for trends in emission <br />sources over time. The emissions inventory comparison and analysis will be <br />completed by December 31, 2003. <br /> <br />c. Modeling <br />1. Base case modeling will be completed by November 30,2003 and future case <br />modeling will be completed by December 31,2003. One or more modeled <br />control cases will be completed by January 31,2004, with final revisions <br />completed by March 31,2004. All modeling: <br />a. Will be SIP quality and perform within EPA's accepted margin of accuracy; <br />b. Will be carefully documented; <br />c. Will sufficiently account for projected future growth in ozone precursor <br />emissions; <br />d. Will be accomplished with technical support and review by TCEQ and <br />concurrently reviewed by EPA; <br />e. Will be used to determine the effectiveness of NOx and/or VOC reductions. <br />The control case(s) will be used to determine the relative effectiveness of <br />different emission reduction strategies and to aid in the selection of <br />appropriate emission reduction strategies. <br /> <br />D. Emission Reduction Strategies <br />1. All adopted Federal and State emission reduction strategies that have been or <br />will be implemented by the December 31,2007 attainment date will be included <br />in base, future and control case modeling. <br />2. Additional local emission reduction strategies under consideration for inclusion in <br />the CAAP will be identified and described by June 16, 2003. <br /> <br />3 <br />
