Dallas / Fort Worth Area

The Dallas/Fort Worth area has impacts from NOx that originates from point sources such as power plants and cement kilns in outlying counties. The concentrated urban area also contributes to the ozone precursors, as do the biogenic emissions given off by area vegetation.

Recently there have been discussions about the DFW SIP Model performance. In order to correct the errors in the model some suggested that new modeling episodes would have to be developed, which takes a considerable amount of time, and would likely prohibit TCEQ from meeting the SIP deadlines. After some review TCEQ has indicated that they believe they can make improvements to the model and will be able to submit the SIP without changing the model episode.

The counties in the DFW area are:

• Collin
• Dallas
• Denton
• Tarrant
• Ellis
• Johnson
• Kaufman
• Parker
