Hello everyone,

| wanted to update you on the correspondence | received this morning. The email and
attachments below were forwarded to me by Terence Teng from Arcose Consulting, the
service provider who conducted the sound level monitoring at OMC1 on Friday, March
6th for Station #3 in the Operations Training Room.

Based on both our internal measurements and the Arcose Consulting noise survey,
there is no indication of hazardous noise exposure. All recorded sound levels were well
below regulatory limits, and there is no occupational hearing risk identified.

| submitted the final report to:
