TCEQ Cement Kiln Study

A study to determine the availability of new air pollution control technologies for cement kilns in the Dallas-Fort Worth area.

Background

On April 15, 2005, a settlement agreement was entered into by the TCEQ, Blue Skies Alliance, the United States Environmental Protection Agency (EPA), and the Portland Cement Association to resolve a lawsuit brought by the Blue Skies Alliance, et al. against the EPA. As part of this settlement agreement, the TCEQ agreed to commission, in consultation with the parties to the settlement, a study to evaluate potential new air pollution control technologies for cement kilns in the Dallas-Fort Worth (DFW) 1997 eight-hour ozone nonattainment area.
