Environmental statement M8 J6, noise levels and frequency of review: EIR release

I understand that an Environmental Assessment was undertaken before the upgrade works for the M8/A8.

In particular I am looking for the noise report covering the junction 6 area and particularly noise levels around the vicinity of Rowntree Cottage at Biggar Road Newhouse at junction 6.

Can you advise what the existing noise levels were measured at in decibels and what the predicted levels would be following the upgrade.

Can you also confirm that the noise levels will be reviewed every 5 years.
