DALLAS (AP) - TXU Corporation says it will add systems designed to reduce emissions of mercury from its coal-fired power plants.
Dallas-based TXU says it's the country's largest voluntary program to reduce mercury pollution emissions.
TXU Wednesday is scheduled to ask state regulators to approve a new coal-fired plant that's raised environmental concerns.
TXU was joined in its announcement by private equity firms Kohlberg Kravis Roberts and Texas Pacific Group.
The two are trying to close their 32 billion dollar purchase of TXU.
Waco Mayor Virginia DuPuy says TXU is making a significant commitment to cleaner air ahead of new rules by the Environmental Protection Agency.
Waco is among the cities closest to the proposed location of two new coal-burning units at Oak Grove, which comes up for state review today.
