Remarks:
(a)
*Due
to the presence of deployed silt curtain systems at the site boundaries of
the Contract, some of the transect lines shown in Figure 2.4 could not be
fully surveyed during the regular survey. Transect 10 is reduced from 6.4km
to approximately 3.6km in length due to the HKBCF construction site.
Therefore the total transect length for both NEL and NWL combined is reduced
to approximately 108km.
(b)
#Coordinates
for transect lines 1, 2, 7, 8, 9 and 11 have been updated in respect to the
Proposal for Alteration of Transect Line for Dolphin Monitoring approved by
EPD on 19 August 2015.

Remarks:
(a)
*
Due to the presence of deployed silt curtain systems at the site boundaries
of the Contract, some of the transect lines shown in Figure 5.1 could not be
fully surveyed during the regular survey. Transect 10 is reduced from 6.4km
to approximately 3.6km in length due to the HKBCF construction site.
Therefore the total transect length for both NEL and NWL combined is reduced
to approximately 108km
