Five die at Georgetown generating plant

GEORGETOWN, Colo. ” Investigators are trying to determine how five workers trapped 1,000 feet inside an empty underground water tunnel died following a chemical fire at a hydroelectric plant.
Crews who entered from the bottom of the sloping tunnel to put out the fire discovered the bodies late Tuesday, Clear Creek County undersheriff Stu Nay said.
They were among a group of nine contract maintenance workers in the tunnel when a machine used to coat the inside of the 4-foot-wide pipe with epoxy caught fire, said Xcel Energy spokeswoman Ethnie Groves. Xcel refused to release the name of the contractors’ employer.
Four workers below the fire were able to scramble out of the bottom of the 4,000-foot-long tunnel. Two of the four were treated for chemical inhalation, and one was airlifted to a hospital, Groves said.
The coroner’s office was working to identify the workers.
Officials initially expressed hope that the trapped workers could be saved. Groves first reported that authorities had communicated with the five by radio and that the men said they were unhurt.
The nine workers were sealing the inside of the pipe to prevent corrosion when equipment they were using malfunctioned and ignited a fire at 2 p.m.
“We want to express our deepest sympathies to the families, friends and co-workers of those who died,” said Tim Taylor, president and CEO, Public Service Company of Colorado, an Xcel Energy company. “Certainly, we’ll be working closely with the authorities to investigate what happened.”
The underground tunnel delivers water from a reservoir to turbines that generate electricity and empties into a second, smaller reservoir. The plant is located high in the Rocky Mountains of Colorado.
Xcel said the tunnel initially rises 1,500 feet at a gentle sloping angle, then another 1,500 feet at a 15-degree angle. The pipe then rises 1,000 feet at a 55-degree angle before running vertical for its final 50 feet.
The smoldering fire broke out about halfway into the pipe. The five workers were trapped at the junction of the 15-degree pipe and the 55-degree pipe, Xcel said.
Personnel from at least a dozen agencies, including a mine rescue crew and an Alpine rescue team, rushed to the site 2 miles outside Georgetown, a former mining town whose mountain views, Victorian buildings and bighorn sheep attract tourists.
Officials were able to lower breathing masks and pipe in oxygen to the men, who had scrambled up the tunnel and sought shelter behind a temporary valve used to prevent water from seeping into the pipe, said Maj. Rick Albers of the Clear Creek County sheriff’s department.
At 5:40 p.m., the mine crew entered the bottom of the tunnel to extinguish the fire. At the top of the tunnel, rescuers waited to rappel their way down to reach the workers but authorities later said they decided it would be safer to reach the workers from the bottom.
The hydroelectric plant generates electricity by releasing water from the top reservoir into the lower reservoir, then pumping the water back to the upper reservoir. It was completed in 1967.
