Of particular concern are fly wheels associated with continuous power supply units. These would allow enough time for generators to kick onshould Global Foundries lose power, and some of them are quite loud. A full power outage at the fabrication facility could be a costly disaster forGlobal Foundries.
GF has employed many strategies to combat noise, including anearthen berm approximately 60 feet high, five noise monitoring censors placed along fence lines and periodic checks with handheld censors from places such asrooftops. Additionally, special baffles have been installed to filter noise on the electrical services building.
That building had four custom-made baffles installed last fall.Two were placed on the south side, and two on the north side of the building.
“Those were not part of the original design,” said Bullard. “Wewanted to be a good neighbor and reduce noise if we could.”
Global Foundries has been working with Novus Engineering of Delmar on noise issues, and the company recommended the baffles.
“We have reduced the noise there by 14 percent,” said Bullard.
GF is now in the midst of a project that includes the installation of exhaust fan stack silencers on the roof of the electrical services building. The silencers will be placed on top of a piping system onthe roof and should be completed in June.
Aportion of a letter sent to residents by GlobalFoundries reads, “The newExhaust Fan Stack Silencers are expected to help further reduce the noisecoming from the Fab 8 site. This is an intensive project requiring custom manufacturing equipment and specialized engineering and design work to remodelthe structure of the building, but we are moving forward quickly.”
The Global Foundries facility is expected to be completed by the end of the year. Global Foundries will hold a quarterly “Neighborhood Meeting” on Thursday, March 22, from 6 to 7 p.m. at the Fab 8 Admin building. The meeting is open to the public.
