· New emission control strategies in the DFW area, combined with existing rules implemented under the previous one-hour federal ozone standard, are predicted to bring the area into attainment of the new, more stringent, eight-hour ozone standard by the EPA’s 2010 deadline.
· The HGB ozone nonattainment area will take longer to reach attainment. Texas, therefore, will submit a SIP showing the rate of progress toward attainment as well as new emission control requirements for volatile organic compound (VOC) sources in Houston, strategies for reducing NOx, and elements required by the Federal Clean Air Act such as emissions inventory.
