There
were two action level exceedances of turbidity, one action level exceedance of suspended
solid and one limit level exceedance of suspended solid on impact water quality
monitoring at station SR4(N) and IS8 during mid-flood tide
recorded on 24 March 2017. Besides, there were two action level exceedances of suspended
solid on impact water quality monitoring at station SR4(N)
and IS8 during
mid-ebb tide recorded on 24 March 2017. After investigation, there was
concluded that the six exceedances were not relevant to this Contract since
there was no marine works or barge of
this Contract worked at HKBCF reclamation site near the sea area or area near
the monitoring station SR4(N) and IS8
from 22 March 2017 to the water quality monitoring period on 24 March 2017
which was unlikely to generate suspended solid and thus deteriorate the
turbidity in the marine water to cause the suspended solid and turbidity exceedances recorded at the
monitoring station SR4(N) and IS8 during mid-flood tide and mid-ebb tide on 24
March 2017.
There was one action level exceedance of suspended
solid on impact water quality monitoring at station IS(Mf)11
during mid-flood tide recorded on 28 April 2017. After investigation, there was concluded that the exceedance was not relevant to this Contract since
