Breaches
of Action and Limit Levels
Summary of Action
and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level at AMS6 shall
be referred to the monthly EM&A report prepared by Contract No. HY/2011/03.
There was no Action and Limit Level exceedance
of 1-hr TSP level and 24-hr TSP level
recorded at station AMS7 by the Environmental Team of Contract No. HY/2010/02 during the reporting period.
There was no Action and Limit Level exceedance
for noise recorded at
station NMS2 and station NMS3B by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
There was one Limit Level exceedance of SS a on impact water quality monitoring at
station SR4(N) during mid-flood tide recorded
on 20 May 2016. After
investigation, there was
concluded that the exceedances were not relevant to this Contract since there
was no marine works carried out by this Contract during the reporting period. The Investigation Report No. 003 (including
the causes of exceedance, action taken and recommendation for mitigation) for
Action or Limit Level Non-compliance was provided in Appendix J. There was no
Action and Limit Level
exceedance recorded on other date at the
