Natural Gas Starting to Flow in Denison

12-1-03 - More than 8,400 TXU customers have been without service since early Sunday morning. Hundreds of TXU employees have been going door to door ever since, restoring gas pressure and relighting pilot lights. Its a tedious process that could take until late Tuesday night or Wednesday to finish. TXU officials say the problem began early Sunday morning with what may have been a 'regulator' malfunction. Service at the local hospital and school system have been restored.
