A Luminant spokesperson said the company will continue to monitor its new Sandow 5 power plant for noise. This view is from US 77, near the spot where the loudest vibrations were noted. Reporter/Mike Brown A Luminant spokesperson said the company will continue to monitor its new Sandow 5 power plant for noise. This view is from US 77, near the spot where the loudest vibrations were noted. Reporter/Mike Brown The buzz southeast of Rockdale is that the buzz isn't as bad as it was.

Luminant's Sandow Power Plant Unit 5 came back on-line last week, after being down for 12 days to repair noise and vibrations that had been the subject of complaints in the area.

Ashley Monts, Luminant spokesperson, said Unit 5 came back on-line Wednesday, Nov. 18, and was re-connected to the state's power grid the next day.

The project was termed "significant planned maintenance" and Luminant officials said steel plates were installed at the new unit to reduce vibrations and noise.

"We believe it (the maintenance) has signifi cantly reduced vibration noise from the plant," Monts said Thursday.

'Hopefully corrected'

Initial response from the area indicates that may very well be the case.

"The horrible noise emanating from Sandow 5 has not been noted," Curtis Chubb told The Reporter on Friday. "So, hopefully, they have corrected their engineering error."

Chubb who lives near Milano, wrote a letter to the editor, published in the Oct. 15 Reporter, complaining about a low-frequency hum emanating from Unit 5.

And an unscientific survey conducted by The Reporter, comparing sound and vibration levels at five locations in the area before and after the maintenance work found the noise still audible but at a reduced level.

'Appreciative'

Some persons who live closer to Unit 5 had reported vibrations so strong windows shook and water jiggled in a glass.

Luminant said it had met with persons expressing concern over the situation.

"We will continue to monitor operations as the plant continues to optimize performance through startup and conditioning," Monts said.

"We want our neighbors to k now that we are ex tremely appreciative of their understanding," she said.
