2.1 Summary of EM&A Requirements
The ET of the Contract or another ET of the HZMB project is required to
conduct dolphin monitoring at 23 transects as part of EM&A programme if
these transects are no longer covered under Contract No. HY/2010/02. The dolphin monitoring should adopt line-transect
vessel survey method. The survey follows pre-set and fixed transect lines in the
two areas defined by AFCD as: Northeast Lantau survey area; and

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. |

All the
figures given in the table are used for reference only and the EPD may amend
the figures whenever it is considered as necessary. |

If
exceedance(s) at these station(s) is/are recorded by the ET of the Contract or
referred by the other ET under the HZMB project to the Contract, the ET of the
Contract will carry out an investigation and findings will be reported in the
quarterly EM&A Report.

The exceedance is still under investigation by Contract No.
HY/2010/02. The Investigation Report (including the causes of exceedance,
action taken and recommendation for mitigation) for Action or Limit Level
Non-compliance will be prepared by the ET of Contract No. HY/2010/02 and
detailed in the quarterly EM&A Report prepared for
Contract No. HY/2010/02. The implementation of Regular Marine Travel Route Plan (RMTRP) for the
above mentioned two round trips of marine transportation undertaken by Contract
No. HY/2013/02 during the reporting period were checked by the ET. The Regular Marine Travel Route Plan were
prepared and given to the Caption to use in order to minimize the chance of vessel collision
