Notes: 1.
"depth-averaged" is calculated by taking the arithmetic
means of reading of all three depths. |
|
|||
2. For DO, non-compliance of
the water quality limits occurs when monitoring result is lower than the
limits. |
|
|||
3. For turbidity, SS, non-compliance of the
water quality limits occurs when monitoring result is higher than the limits. |
|

4.3
Monitoring Result
4.3.1 The monitoring
results for the monitoring stations showed in Table 4.1 are reported in
the monthly EM&A Report prepared for Contract No. HY/2010/02. There were three
Action Level exceedances of SS at station IS(Mf)11,
SR6
and SR7 during mid-flood tide recorded on 03 October 2016, one Action Level
exceedances of SS at station SR6 during mid-flood tide recorded on 17 October 2016
and one Action Level exceedances of SS at station SR6 during mid-flood tide
recorded on 19 October 2016.
4.3.2
Exceedances
were not due to operation of the works under Contract No. HY/2013/02 because there was no marine works or barge of this
Contract during October 2016 which was unlikely to generate suspended solids in
the marine water. Secondly, the SS exceedances were recorded during flood tide
in which the monitoring station IS(Mf)11 and SR7 is located at upstream of the works area of this Contract and the
monitoring station SR6 is located at downstream of the monitoring stations IS10
and SR5 which are located in between the works area of
this Contract. There were no SS exceedance recorded at the monitoring station
IS10 and SR5. Therefore, it is unlikely that the SS exceedances recorded at IS(Mf)11,
SR6 and SR7 during mid-flood tide on 03
October 2016, and SS exceedances recorded at SR6 on 17 and 19 October 2016 during
mid-flood tide were contributed by the works under Contract No. HY/2013/02. The
water quality mitigation measures as mentioned in EM&A Manual and EP was
fully implemented in this Contract which including maintenance of the silt
curtain on a daily basis etc. Hence, the exceedances were considered as
non-Project related.
4.3.3
After
investigation, there were concluded that the exceedances were not relevant to
this Contract due to the above mentioned reasons. The Investigation Reports No.
004, 005 and 006 (including the causes of exceedance, action taken and
recommendation for mitigation) for Action or Limit Level Non-compliance were provided
in Appendix J. There was no Action
and Limit Level exceedance recorded on other date at the monitoring stations showed
in Table 4.1 by the Environmental
Team of Contract No. HY/2010/02 during the reporting period.
4.3.4
Although the exceedances were not relevant to this
Contract, the Contractor was reminded to ensure provision of ongoing
maintenance to the silt curtains and to carry out maintenance work once defects
were found.
