Subject: Notice/ Adams Street Micro-Tunneling operation tonight (4/4/2016)

To All,

Our Contractor, Skanska-Jay Dee ( SKJD) has resumed mining the adit connection to the First Street Tunnel under Adams Street. SKJD will cease mining operations for the day  on/near 8PM. However, within the construction staging area SKJD will need to continue to operate a machinery until about midnight.  The centrifuge is a large machine with a rapidly rotating container.  It is used to separate fluids, in this case separating drilling fluids from the settling clay particles.  The drilling fluid is reused. The machine will need to continue to operating until about midnight. The operation generates a constant humming sound.  Hopefully, with the weather conditions tonight, it will not be as much of a problem.  Mining will resume tomorrow morning.

SKJD is in the process of notifying abutters about the centrifuge operating late. As always, if you have questions or concerns please call the 24/7 FST Hotline at (844) FST-INFO/ (844) 378-4636.

Thank you for your understanding.  

Sincere Regards, Tom
