1 Introduction
1.1
Background
1.1.1 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.
1.1.2 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.
1.1.3 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 into account the design of the 3RS road network
designed around the expanded T2 building. 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.
1.1.4 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 100m 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.
1.1.5 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 involve 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 EPD in November
2018 which concluded that the change of implementation agent form 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 was granted to AAHK in December 2018 in
accordance with Section 12 of EIAO.
1.2
Purpose of the
Manual
1.2.1 This Environmental Monitoring and Audit (EM&A) Manual
outlines the monitoring and audit programme proposed for the HKIA-HKBCF Road
Connection (hereafter referred to as the Project). In accordance with Condition
3.1 of Further Environmental Permit (FEP) (EP No. FEP-01/353/2009/K), an
updated EM&A Manual shall be prepared before the commencement of
construction works.
1.2.2 The purpose of this EM&A Manual (hereafter referred to
as the Manual) is to guide the setup of an EM&A programme to ensure
compliance with the recommendations in the approved Environmental Impact
Assessment (EIA) Report of Hong Kong - Zhuhai - Macao Bridge Hong Kong Boundary
Crossing Facilities – Investigation (hereinafter referred to as “the EIA
Report”) and the findings from the ERR, to summarize appropriate EM&A
requirements in accordance with the information and recommendations described
in the EIA Report and by taking into account any specific site conditions that
may be changed before the construction of HKIA-HKBCF Road Connection.
1.2.3 This Manual is prepared by making
reference to the framework of the EM&A Manual of the HZMB HKBCF –
Investigation and the information and recommendation as described in ERR as
approved by EPD. AAHK is the implementation agent for the construction of
HKIA-HKBCF Road Connection and the duties for EM&A works have been
presented in this Manual.
1.2.4 In this updated submission, Section 6 incorporates the
revised quantity of marine sediment to be excavated as estimated by the
Contractor. Section 13 incorporates the latest change on the landscape planting
proposal.

3.4.2 The Contractor should adopt this WMP as a basis to develop
their own contract-specific WMPs. The contract-specific WMPs should be updated from time to time
and submitted to the ET and IEC for their verification and AAHK for agreement.
3.5
Environmental
Management Plan
3.5.1 A systematic EMP shall be prepared by the Contractor to
ensure effective implementation of the mitigation measures, monitoring and
remedial requirements presented in the EIA, EM&A and Environmental
Mitigation Implementation Schedule (EMIS). ET and IEC will audit the
implementation status against the EMP and advise the necessary remedial actions

3.6
Construction
Method Statement
3.6.1 In case the Contractor would like to adopt alternative
construction methods or implementation schedules, it is required to submit
details of methodology and equipment to the PM for approval before the work
commences. Any changes in construction method shall be reflected in a
revised EMP or the Contractor will be required to demonstrate the manner in which the EMP should accommodate the proposed
changes.
4 Air
Quality
4.1
General
4.1.1 As the Project will involve only construction of HKIA-HKBCF
Road Connection on the reclaimed land already formed under the HKBCF project,
the construction dust and emissions from construction works of this nature and
size would be limited. According to the ERR, with the implementation of the
recommended mitigation measures in Section 5.2, the construction phase air
quality at all identified air sensitive receivers would comply with the Air
Quality Objectives and no adverse air quality impacts would be anticipated from
the construction of the Project. In view of the above, no air quality monitoring
during the construction phase of the Project is proposed.
4.2
Mitigation
Measures
4.2.1 Condition 2.6 of the FEP has stipulated that watering shall
be undertaken at least eight times per day on all exposed soil within the
Project site and associated work areas throughout the construction period. In
addition, relevant dust control measures such as surfaced with crushed stone or
coarse gravel on the temporary access road, enclosure for handling of dusty
materials, and wheel wash facilities recommended in the EIA Report shall be
implemented to minimise generation of dust. All relevant mitigation measures
are summarised in the Environmental Mitigation Implementation Schedule (EMIS)
in Appendix B.
5 Noise
5.1
General
5.1.1 According to the EIA Report, the nearest noise sensitive
receivers (NSRs) from the Project is located in the
existing Tung Chung New Town at distance of about 2 km from the construction
work site of the Project. Given the large separation distance between the works
area and the NSRs, no adverse construction noise impact would arise with
appropriate mitigation measures in place. In view of the above, no noise
monitoring during the construction phase of the Project is proposed.
5.2
Mitigation
Measures
5.2.1 The EIA Report recommended construction noise control
measures including:
· good site practices to limit noise emissions at the sources;
· use of quiet plant and working methods;
· use of site hoarding as noise barrier to screen noise at ground level of NSRs;
· use of shrouds/ temporary noise barriers to screen noise from relatively static powered mechanical equipment (PME);
· scheduling of construction works outside school examination periods in critical area; and
· alternative use of plant items within one worksite, wherever practicable.
5.2.2 Relevant mitigation measures are summarised in the EMIS in Appendix B.
6 Sediment
Quality
6.1
General
6.1.1 Based on the EIA Report and the Environment, Transport and
Works Bureau Technical Circular (Works) (ETWB TCW) No. 34/2002 on the
Management of Dredge/Excavated Sediment, the marine sediments arising from the
works within the Project works area were Category L sediments and Category M
sediments that had passed the biological screening, which could be handled
through open sea disposal and open sea disposal at dedicated sites
respectively. In accordance with the
Condition 3.27 of the EP (EP No.: EP-353-2009/K), if any off-site disposal is
required, the excavated marine sediment shall be disposed of at the designated
disposal sites within Hong Kong as allocated by the Marine Fill Committee or
other locations as agreed by EPD. The
procedures for seeking disposal shall comply with requirements provided in ETWB
TCW No. 34/2002.
6.1.2 According to the Contractor, the volume of marine sediment
to be excavated from the construction of the foundations of the Project would
be about 4,500 m3. It is recommended that these marine sediments
excavated may be treated using cement/ solidification/ stabilization techniques
and reused onsite or offsite for backfilling and/or landscaping so that the
need for offsite disposal is avoided as far as practicable. As the location where the treated marine
sediment to be re-used has yet to be confirmed at the time of the preparation
of this manual, it is subject to the final construction design.
6.1.3 The treated marine sediments using
cement/solidification/stabilization techniques should be tested against the
Toxicity Characteristics Leaching Procedure (TCLP) (as shown in Table 6.1) which were recommended in the EPD’s Practice
Guide for Investigation and Remediation of Contaminated Land. The
treated sediment should also be tested against relevant engineering
requirements to confirm their suitability as backfilling material for
respective areas of different future uses. Unconfined Compressive Strength
(UCS) will be tested and defined based on respective engineering requirements.

Notes:
1) Universal Treatment Standard – US 40 CFR 268.48
2) Antimony and Barium are excluded from the above table as they are not considered as a contaminant of concern for the sediment quality in the EIA study. For Copper, it must be reduced by at least 90% in mobility for copper through cement stabilization/solidification remedial treatment. The reduction of mobility of copper (leachable metals contaminant) should be confirmed through TCLP tests (i.e. to carry out TCLP test for the untreated sediment and for the sediment after treatment and to compare the concentrations of copper in the leachates). By taking account into the scenario where the Copper concentration of the sample is below the limit of the reporting (LOR) of the laboratory analysis (Copper: 0.1 mg/L), the treatment target is considered to be achieved in case the Copper concentration of the sample taken after treatment is smaller than the LOR.
6.1.4 The testing frequency for TCLP is one sample per 50 m3
of the broken up solidified mixture of the treated marine sediment mix for the
first 1,000 m3 of the treated marine sediment. Provided that the
samples meet the UTS for the tested parameters shown in Table
6.1 and the UCS test, the subsequent testing frequency will be reduced
to be at least two samples per 10,000 m3. In the event that the
treated marine sediment mix does not meet the specified treatment target, the
concerned whole batch should be crushed and the
material would be further handled and treated as necessary. The testing
frequency should be revised to one sample per 50 m3 (with two
further samples kept for contingency) and treated samples should be taken for
laboratory testing. Once the UTS and UCS for the relevant tested parameters are
attained, the previous sampling frequency should be resumed
6.1.5 In the worst case scenario where
cement/solidification/stabilization techniques cannot achieve the specified
treatment target of the excavated marine sediment, the Contractor shall propose
alternative method(s) to treat the marine sediment. The Contractor shall seek
review without objection from the ET and IEC, and acceptance by EPD on the
proposed alternative method(s).
6.2
Mitigation
Measures
6.2.1 The proposed mitigation measures are summarised in the EMIS
in Appendix B.
7 Waste
Management
7.1
General
7.1.1 Measures including the opportunity for on-site sorting,
reusing excavated materials for reclamation etc, are devised in the
construction methodology to minimise the surplus materials to be disposed
off-site. Proper disposal of chemical waste should be via a licensed waste
collector.
7.1.2 EM&A requirements for waste management are only required
during the construction phase. Effective management of waste during the
construction phase shall be monitored through site audit programme. The aims of
the waste audit are:
· to ensure the waste arising from the works are handled, stored, collected, transferred and disposed of in an environmentally acceptable manner; and
· to encourage the reuse and recycling of material.
7.1.3 A trip-ticket system should be operated to monitor all
movements of chemical wastes which will be collected by a licensed collector to
a licensed facility for final treatment and disposal.
7.2

7.3
Mitigation
Measures
7.3.1 All the relevant mitigation measures for the Project
recommended in the EIA Report are summarised in the EMIS in Appendix B.
8 Water
Quality
8.1
General
8.1.1 As the construction works of the Project will be land-based,
the key water quality issues of the Project include water quality impacts from
construction site runoff, and wastewater and sewage generated from construction
activities. Mitigation measures are recommended in the EIA Report for
controlling potential water pollution from land works and are considered
relevant and adequate for the Project.
8.1.2 Prior to the commencement of the construction work, a
detailed site drainage management plan should be prepared by the
Contractor. The plan should cover measures to minimize all potential
water quality impact arising from the surface runoffs of the Project. The plan
shall be reviewed by ET and IEC before submission to EPD.
8.2
Mitigation
Measures
8.2.1 The construction water quality control measures recommended
in the EIA Report such as preventing direct discharge of wastewater from
temporary site facilities, providing storm drainage with silt removal
facilities, controlling site surface runoff, preventing oil and chemical
spillage, and other measures outlined in the Practice Note for Professional
Persons (ProPECC), Construction Site Drainage (PN
1/94) should be adopted to control any potential water quality impacts.
Mitigation measure to minimise water quality impacts from construction site
runoff and wastewater and sewage generated from construction activities
include:
(i) Provision of site drainage systems over the entire construction site with sediment control facilities. Regular inspection and maintenance of the site drainage systems are required to ensure proper and efficient operation at all times.
(ii) Sediment-laden wastewater generated from foundation construction work, wheel washing, site runoff and wastewater with high concentration of SS as generated from any construction activities should be treated using sedimentation tanks or package treatment systems. Treated wastewater can be reused for vehicle washing, dust suppression and general cleaning. Bentonite slurry used in bore-pile construction should be reconditioned and reused to minimise the disposal volume of the used slurry.
(iii) The construction programme should be properly planned to avoid soil excavation in rainy seasons. Exposed stockpiles of excavated soils or construction materials should be covered with tarpaulin or impervious sheets to avoid release of pollutants into the drainage channels.
(iv) Licensed waste collector should be employed for the collection and disposal of the sewage generated from portable toilets.
(v) Wheel washing facilities should be installed at all site entrances/exits.
(vi) An emergency plan should be developed by the Contractor to deal with accidental spillage of chemicals.
8.2.2 A license under the Water Pollution Control Ordinance should
be obtained prior to any discharge of wastewater under the Project. All
discharge should be in compliance with the conditions
as stipulated in the license.
8.2.3 All the relevant mitigation measures recommended in the EIA
Report are summarised in the EMIS in Appendix B.
9 Ecology
9.1
General
9.1.1 The construction works of the Project will be undertaken on
reclaimed land with no existing terrestrial ecological habitat. No
potential ecological impact associated with the Project works is identified and
therefore no mitigation measures are required.
10 Fisheries
10.1 General
10.1.1 As the construction works of the Project will be undertaken
on reclaimed land, no potential impacts related to fisheries and marine culture
were identified and therefore no mitigation measures are required.
11 Cultural Heritage
11.1 General
11.1.1 The Project works locate on reclaimed land with no existing
cultural heritage resources. No adverse impact on built heritage, marine
archaeology, and terrestrial archaeology is anticipated. Hence, further investigation
or mitigation measure is not required.
12 Hazard To
Life
12.1 General
12.1.1 No blasting work will be involved for the construction of
the Project. Therefore, no explosives Quantitative Risk Assessment (QRA) was undertaken and no mitigation measures is required.
13 Landscape & Visual
13.1 General
13.1.1 A number of design measures, such as
aesthetic architectural on related infrastructure, streetscape elements,
landscape planting and other measures including night-time lighting control
were recommended in the EIA Report for minimizing landscape and visual impacts
from the HKBCF project. This section outlines the relevant monitoring and audit
of these measures applicable to this Project.
13.2 Monitoring Details
13.2.1 The design, implementation and maintenance of landscape
mitigation measures should be checked by ET to ensure that any potential
non-conformity between the proposed landscape measures and any other works of
the project shall be resolved as early as practical without affecting the
implementation of the mitigation measures.

Detailed
Design Phase
13.2.2 The relevant mitigation measures, which were proposed in the
EIA Report to mitigate the landscape and visual impacts, were embodied into the
detailed engineering design, landscape design drawings and contract
documents. The Detailed Design were checked to ensure that the measures
are fully incorporated. The agent for implementation and checking of the
measures are summarized in EMIS in Appendix B.
13.2.3 The following mitigation measures were proposed to avoid and
reduce the identified impacts:
· Minimize the footprint of project and that the quantity of landscape character units and landscape resources affected;
· Minimize temporary works areas for construction works;
· Undertaking good site practices by applying hydroseeding on temporary stockpiles and reclamation areas;
· Conservation of topsoil for reuse; and
· Waste limitation by recycling of felled trees into woodchip mulch for use in landscaped areas.

13.5.1 The mitigation measures as recommended in the EIA Report are
summarised in the EMIS in Appendix B.
14 Site Environmental Audit
14.1 General
14.1.1 Site inspection provides a direct means to initiate and
enforce specified environmental protection and pollution control
measures. These shall be undertaken routinely to inspect construction
activities in order to ensure that appropriate
environmental protection and pollution control mitigation measures are properly
implemented. Site inspection is one of the most effective tools to
enforce the environmental protection requirements at the works area.
14.1.2 The ET Leader shall be responsible for formulating the
environmental site inspection, the deficiency and action reporting system, and
for carrying out the site inspection works. Within 21 days of the
construction contract commencement, he shall submit a proposal for site
inspection and deficiency and action reporting procedures to the IEC for
agreement, and to PM for approval. The Contractor’s proposal for
rectification shall be made known to ET, IEC and PM.
14.1.3 Regular site inspections shall be carried out at least once
per week. The areas of inspection shall not be limited to the
environmental situation, pollution control and mitigation measures within the
site. It should also review the environmental situations outside the
works area which is likely to be affected, directly or
indirectly, by the site activities. The ET Leader shall make reference to the following information in conducting
the inspection:
(i) EIA recommendations on
environmental protection and pollution control mitigation measures;
(ii)
Works progress
and programme;
(iii)
Individual works
methodology proposals (which shall include proposal on associated pollution
control measures);

Contract
specifications on environmental protection;
(v)
Relevant environmental
protection and pollution control laws; and
(vi)
Previous site
inspection results.
14.1.4 The Contractor shall keep the ET Leader updated with all
relevant information on the construction contract necessary for him to carry
out the site inspections. Inspection results and associated
recommendations for improvements to the environmental protection and pollution
control works shall be submitted to the IEC and the Contractor within 1 working
day. The Contractor shall follow the procedures and time-frame
as stipulated in the environmental site inspection, and the deficiency and
action reporting system formulated by the ET Leader, to report on any remedial
measures subsequent to the site inspections.
14.1.5 Ad-hoc site inspections shall also be carried out if
significant environmental problems are identified. Inspections may also
be required subsequent to receipt of an environmental
complaint, or as part of the investigation work, as specified in this Manual.
14.2 Compliance with Legal and
Contractual Requirements
14.2.1 There are contractual environmental protection and pollution
control requirements as well as environmental protection and pollution control
laws in Hong Kong with which construction activities must comply.
14.2.2 In order that the works comply with the contractual
requirements, all works method statements submitted by the Contractor to PM for
approval shall be sent to the ET Leader for vetting to ensure sufficient
environmental protection and pollution control measures have been
included. The implementation schedule of mitigation measures is
summarised in Appendix B.
14.2.3 The ET Leader shall also review the progress and programme
of the works to check that relevant environmental laws have not been violated,
and that any foreseeable potential for violating laws can be prevented.
14.2.4 The Contractor shall regularly copy relevant documents to
the ET Leader so that checking can be carried out. The document shall at
least include the updated Works Progress Reports, updated Works Programme, any
application letters for different licence / permits under the environmental
protection laws, and copies of all valid licences / permits. The site
diary shall also be available for the ET Leader's inspection upon his
request.
14.2.5 After reviewing the document, the ET Leader shall advise the
IEC and Contractor of any non-compliance with contractual and legislative
requirements on environmental protection and pollution control for them to take
follow-up actions. If the ET Leader's review concludes that the current status on licence / permit application and any
environmental protection and pollution control preparation works may result in
potential violation of environmental protection and pollution
control requirements, he shall also advise the Contractor and PM
accordingly.
14.2.6 Upon receipt of the advice, the Contractor shall undertake
immediate actions to correct the situation. The PM shall follow up to
ensure that appropriate action has been taken in order to
satisfy contractual and legal requirements.
14.3 Environmental Complaints
14.3.1 Complaints shall be referred to the ET Leader for
action. The ET Leader shall undertake the following procedures upon
receipt of any complaint:
(i) log complaint and date of
receipt onto the complaint database and inform the IEC immediately;
(ii) investigate the complaint to determine
its validity, and assess whether the source of the problem is due to works activities;
(iii) identify mitigation measures
in consultation with the IEC if a complaint is valid and due to works;
(iv) advise the Contractor if
mitigation measures are required;
(v) review the Contractor's
response to identified mitigation measures, and the updated situation;
(vi) if the complaint is
transferred from the EPD, submit interim report to the EPD on status of the
complaint investigation and follow-up action within the time frame assigned by
the EPD;
(vii) undertake additional
monitoring and audit to verify the situation if necessary, and review that circumstances leading to the complaint do not recur;
(viii) report investigation results and
subsequent actions to complainant (if the source of complaint is EPD, the
results should be reported within the timeframe assigned by the EPD); and
(ix)
record the
complaint, investigation, the subsequent actions and
the results in the monthly EM&A reports.
