Introduction
1.1
Background
To
connect the Hong Kong-Zhuhai-Macao Bridge (HZMB) Hong Kong Boundary Crossing
Facilities (HKBCF) with the Hong Kong International Airport (HKIA), roads
including an elevated bridge structure (hereinafter referred to as “the HKBCF
Viaduct/Roads”) were proposed as part of the HKBCF project, as described in
Section 4.5 of the approved Environmental Impact Assessment (EIA) report of the
HKBCF project. The HKBCF Viaduct/Roads are located partly within the boundary
of the Airport Island near Terminal 2 (T2) and partly within the boundary of
the land corridor between HKBCF and the Airport Island, i.e., partly within the
HKBCF boundary.
Under
the HKBCF project, the arrangements for the planning of the construction of the
HKBCF Viaduct/Roads were formulated based on the scenario with the existing
two-runway system (2RS) at the HKIA. The portion of the HKBCF Viaduct/Roads
falling within the boundary of the land corridor between HKBCF and HKIA were
originally planned to be constructed by Highways Department (HyD) of the Government
of the Hong Kong Special Administrative Region (HKSARG) as part of the HKBCF
project.
With
the planned expansion of HKIA into a three-runway system (3RS), a revised
layout of the HKBCF Viaduct/Roads (the revised layout is hereinafter referred
to as the proposed “HKIA-HKBCF Road Connection”) was formulated as part of the
P282 Terminal 2 Expansion Design Consultancy of Airport Authority Hong Kong
(AAHK). The proposed HKIA-HKBCF Road Connection has taken the design of the 3RS
road network designed around the expanded T2 building into account. In addition
to preparing the detailed design, it was also considered that the proposed
HKIA-HKBCF Road Connection within the HKBCF boundary would be constructed by
AAHK instead of HyD along with the 3RS road network planned within the Airport
Island. Upon completion of the construction works, the new HKIA-HKBCF Road
Connection outside the Airport Island would be handed over to HyD for future
operation and maintenance.
The
EIA for the HKBCF project, which covered the HKBCF Viaduct/Roads as a
Designated Project (DP) based on the requirements set out in Item A.8. (i.e., a
road bridge more than 100 m in length between abutments) in Part 1 of Schedule
2 to the Environmental Impact Assessment Ordinance (EIAO) (Cap. 499), was completed
and approved (EIA Register No.: AEIAR-145/2009) and an Environmental Permit
(EP) (EP No.: EP-353/2009) was granted under the EIAO to HyD.
On the
other hand, the 3RS EIA had subsequently commenced and completed (EIA Register
No.: AEIAR-185/2014) by AAHK, and it has already taken the layout of the
proposed HKIA-HKBCF Road Connection into account and has assessed the relevant
cumulative environmental impacts. The planned change in implementation agent
from HyD to AAHK for the construction of the proposed HKIA-HKBCF Road
Connection outside the Airport Island would, involves a transfer of
corresponding responsibilities under the HKBCF EP from HyD to AAHK. To this
end, an Environmental Review Report (ERR) was prepared and submitted to
Environmental Protection Department (EPD) in November 2018 which concluded that
the change of implementation agent from HyD to AAHK for the construction of
HKIA-HKBCF Road Connection would not result in any exceedance or violation of
the environmental performance requirements set out in the approved HKBCF and
3RS EIAs and the mitigation measures identified in these EIAs remained relevant
and valid. A Further Environmental Permit (EP No. FEP-01/353/2009/K) for the
construction of the HKIA-HKBCF Road Connection (hereinafter referred to as “the
Project”) was granted to AAHK in December 2018 in accordance with Section 12 of
EIAO. Afterwards, an Environmental Monitoring and Audit Manual for HZMB HKBCF –
The Road Connection between HKBCF and the Airport, Chek Lap Kok (the EM&A Manual)
has been prepared to include appropriate environmental monitoring and audit
(EM&A) requirements in accordance with the information and recommendations
described in the EIA Report and by taking into account the specific site
conditions of the Project under the FEP.
The Project consists of the construction of a road bridge more than 100 m in length between abutments connecting between HKBCF and the HKIA which is part of the work for HZMB-HKBCF. Location of the Project area is shown in Figure 1.1.
Site clearance and preparation works of the Project started in August 2021, and the construction works commenced on 4 October 2021. The summary of construction works programme can be referred to the corresponding Monthly EM&A Reports.

Environmental
Site Inspection and Audit
2.1
General
Implementations
of environmental mitigation measures recommended in the approved HZMB-HKBCF EIA
Report for air quality, noise, water quality, waste management, landscape and
visual aspects for the construction phase of the Project were monitored and
audited by ET and IEC through site environmental inspections of the
construction works and checking of Contractor’s records and submission of
information.
Site inspection findings are summarised in Section 2.2. Audit for waste management is summarised in Section 2.3, while that for landscape and visual measures are summarised in Section 2.4.
2.2
Site
Inspection
Site inspections of
the construction works were carried out on a weekly basis by the ET and at
least once per month by the IEC to monitor the implementation of proper
environmental pollution control and mitigation measures for construction dust,
construction noise, construction waste and wastewater for the Project.
During the reporting
quarter, a total of 13 sessions of environmental site inspections were carried
out and site inspection findings are detailed in the monthly EM&A Reports.
Major site inspection findings that were closed out with corrective actions
undertaken by the Contractor are highlighted as follows:
1.
The
maintenance record of the wastewater treatment facility was not duly
completed. The Contractor should
properly complete the maintenance record of the wastewater treatment facility
daily. The Contractor subsequently completed the maintenance record properly.
2.
Water
in the settling chamber of the wastewater treatment facility was observed
turbid but there was no discharge. The Contractor should provide further
treatment for the wastewater prior to discharge, so that the discharge quality
could meet the discharge license requirement. Subsequently, the Contractor
provided proper treatment for the wastewater.
A summary of
implementation status of environmental protection and pollution control as well
as mitigation measures during the reporting period is provided in Appendix C.
2.3
Waste
Management
In
accordance with the EM&A Manual, the waste generated from construction
activities was audited once per week to determine if wastes are being managed
in accordance with the Waste Management Plan (WMP) prepared for the Project,
and any statutory and contractual requirements. All aspects of waste management
including waste generation, storage, transportation and disposal were assessed
during the audits.
The
Contractor has been registered as a chemical waste producer for the Project.
Construction and demolition (C&D) material sorting was carried out on site.
Sufficient number of receptacles were available for general refuse collection.
Weekly
monitoring was carried out by the ET to check and monitor the implementation of
proper waste management practices during the construction phase according to
the requirement of the Waste Management Plan, EM&A Manual and the
implementation schedule of the waste management mitigation measures in Appendix C.
Summary of construction waste generated during the reporting period is presented in Table 2.1 based on updated information provided by the Contractor.

There
was no non-compliance of the WMP, statutory and contractual requirements during
the reporting period.
Based
on the contractor's additional information, which was reviewed and agreed by
relevant parties including AAHK, ET and IEC, the material excavated from bored
piles foundation works was not classified as marine sediment. The excavated
material would be handled as inert C&D material according to the WMP,
reused onsite or offsite for backfilling so that the need for offsite disposal
is minimised as far as practicable.
