transects
as part of EM&A programme if these transects are no longer covered under
Contract No. HY/2013/04. 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 Northwest Lantau survey area. Figure 3 shows
the
co-ordinates for the transect lines and layout map.

Impact Stations, 7 Sensitive Receiver Stations and 5 Control/Far Field
Stations). Due to topographical conditions of SR3, SR10A
and SR10B(N), the
water quality monitoring (WQM) stations was proposed to be monitored at
alternative WQM stations named as SR3(N), SR10A
(N) and SR10B(N2). The proposal for alternation of
water quality monitoring stations for HZMB HKBCF was justified by the ET
Leader for Contract No. HY/2013/01 on 08 November 2017 and verified by the
