AUSTIN (AP) - Some environmental groups have asked regulators to reconsider their decision to allow TXU to build a coal-fired power plant in Central Texas.
The Texas Commission on Environmental Quality last month approved an air permit for the two-unit plant in Robertson County, about 100 miles northeast of Austin.
The environmental groups fear the plant will foul Austin's skies and pump hundreds of pounds of mercury into the air each year.
Two administrative law judges in 2006 recommended that the permit be denied, saying Dallas-based TXU failed to prove it could meet emissions limits.
TXU says that plant and another proposed near Bryan are needed to meet future energy demand.
