It is considered that the
exceedance is not project-related based on the following reasons:
The distance
between the tunnel construction activities and monitoring stations of stream 2
and 3 are about 1000 meters.
The vertical
distance between Stream 1 and the tunnel construction site is more than 44
meters. Therefore, Stream 1 will not affect by any tunnel construction works as
its elevation is above the tunnel construction site
Rainfall was
recorded during the monitoring date
Waste was observed
on the stream during sampling
