TXI to sue EPA over pollution controls

 A North Texas cement kiln is battling federal regulators over pollution controls. TXI has filed a lawsuit against the federal Environmental Protection Agency. The Dallas-based company wants the government to turn off pollution controls at the kiln after ozone season ends in October. The move would release tonnes of additional ozone-producing pollutants each year.

State regulators say they plan to approve a company request to increase production and reduce controls. EPA officials, however, say the move would hamper efforts to improve air quality. The Fort Worth Star-Telegram reports today that EPA has not formally threatened to overrule the state, but TXI
filed the lawsuit in case it does.
