It is considered that the exceedance is not project-related based on the following reasons:

 

Ÿ   The distance between the tunnel construction activities and monitoring stations of stream 2 and 3 are about 1000 meters.

Ÿ   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

Ÿ   Rainfall was recorded during the monitoring date

Ÿ   Waste was observed on the stream during sampling
