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:
Jaylin Cassady (she/her)
Senior Adjudicator, Claims Intake & Adjudication Services, WorkSafeBC
604-244-6306

It appears Jaylin subsequently shared the report with Mark Holand, who then sent the message below
along with the attachments, also copied to:
