More noise abatement work eyed for Unit 5

Bids out as Luminant pledges to find ‘solution’

Luminant is looking at the possibility of additional work to reduce noise levels at its Sandow Power Plant Unit Five.

“We are currently in the process of bidding this project out,” Ashley Monts, Luminant spokesperson, said Monday. “Once bids have been returned, we’ll evaluate our options and determine the next steps for noise abatement.”

That announcement comes exactly one year after a 2009 outage at Unit 5 which included an initial attempt to reduce noise and vibration.

PETITION— The Reporter has learned that some residents in the Country Club Estates subdivision across Alcoa Lake from Unit 5 had begun discussion of a petition to Luminant over noise issues.

That petition is now on hold pending Luminant’s decision on how to address the issue.

“We are committed to being a good neighbor,” Monts said. “We have visited with homeowners in the area over the past 18 months regarding this issue and hope to continue that dialogue.”

Monts said the plant leadership team has spend much time evaluating various options to reduce noise from the unit.

“We are working toward identifying the right solution to help reduce any unusual noise,” she said.

VIBRATION— The 2009 work came after a number of residents east of Sandow complained about noise and vibration from Unit 5, which went on-line in August of that year.

Some reported vibrations so strong walls shook and water jiggled in a glass.

Luminant installed steel plates during the 12-day planned main- tenance outage in November, 2009.

Residents, especially those living at some distance from Unit 5, reported an improvement.

The Reporter conducted an unscientific survey at five sites ranging up to five miles from Unit 5 and concluded the noise had been reduced some, especially for the area east of US 77

But some area residents over the past year have also continued to report a noise problem,.

“We want our neighbors, and the community, to know that we are committed to finding a solution,” she said.
