Monitoring
Locations
The water monitoring works for the
Contract are covered by Contract No. HY/2013/01 Hong Kong-Zhuhai-Macao Bridge HKBCF ¡V Passenger Clearance Building.
The ET of the Contract or another ET of the HZMB project is required to conduct
water quality monitoring at twenty one
stations (9 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
IEC on 13 November 2017; and submitted to EPD on 29 November 2017, and it was
approved by EPD on 22 December 2017. Table

4.3.2 Since the removal of temporary loading and unloading point by
Contract No. HY/2013/02, which involved marine work, was completed on 10
September 2017 and the area was handed back to Reclamation Contractor with
Contract No. HY/2010/02 on 11 September 2017 for subsequent seawall
construction as
confirmed by RSS, there was no marine works or
barge of this Contract worked at HKBCF reclamation site near the sea area or
area near the monitoring station under Contract No.
HY/2013/02 during June
2018. Hence, specific investigation shall be referred to other ET¡¦s report(s)
under the HZMB Projects in which the respective contract(s) with remaining
marine works on-going for the exceedances recorded in
water quality monitoring during this reporting month. There was no Action and Limit Level exceedance
recorded on other monitoring date at the monitoring stations showed at Table

dolphin monitoring at 24 transects as
part of EM&A programme if these transects are no longer covered under
Contract No. HY/2013/01. 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.
