1.1
The Shatin to Central Link (SCL) is
strategically important for connecting the existing railway lines into an
integrated rail network. The SCL comprises 17 kilometres of rail line that will
connect several existing railway lines, creating two distinct east-west and
north-south railway corridors. It will also provide interchange opportunities,
with six of its ten stations (Tai Wai, Diamond Hill, Homantin, Hung Hom,
Exhibition and Admiralty) providing passengers with either an inter-platform or
interchange for other lines.
1.2
The extension for the north-south
corridor is divided into 2 sections, namely Shatin to Central Link – Mong Kok
East to Hung Hom Section [SCL (MKK – HUH)] and Shatin to Central Link – Hung
Hom to Admiralty Section [SCL (HUH – ADM)]. The overall alignment of the SCL is
shown in Figure No. NEX2213/C/361/ENS/M50/501.
SCL (MKK – HUH) refers to the railway section from the south of Mong Kok East Station
(MKK) to Hung Hom Station (HUH) (hereinafter referred as “the Project”).
Whereas, SCL (HUH – ADM) refers to the railway section from Hung Hom Station
across the harbour to new Exhibition Station (EXH) and Admiralty Station (ADM).
The cut-off demarcation between SCL (MKK – HUH) and SCL (HUH – ADM) are located
at the north of the proposed

2.1
The
EIA Report has recommended landscape and visual mitigation measures for the
construction and operation phases of the Project. This section defines the
audit requirements for effective implementation of the recommended landscape
and visual impact mitigation measures.
2.2
Site
audit on landscape and visual aspects of the Project should be carried out
during the construction phase.
Specific auditing during the operation phase of the Project is not
required, with the mitigation measures recommended in the EIA implemented.
2.3
Potential
landscape and visual impacts have been carefully considered during the
development of the Project design to (1) avoid impacts on important landscape
resources as the first priority; and (2) locate, design and reduce physical
extent of the works as far as possible, as well as identify mitigation
measures, so as to minimize impacts on existing trees and open spaces, and to
minimize the degree of visual impact.
2.4
The
landscape and visual mitigation measures should be incorporated in the detailed
design. The construction phase and operation phase mitigation measures proposed
in the EIA Report are presented in Appendix A. The construction
phase mitigation measures should be implemented as early as possible in order
to minimize the landscape impacts in the construction stage while the
mitigation measures for the operation phase should be adopted during the
detailed design and be built as part of the construction works so that they are
in place on the date of commissioning of the Project.
2.5
Any
potential conflicts among the proposed mitigation measures, the Project works and
operational requirements should also be identified and resolved as early as
practicable. Any changes to the
mitigation measures should be incorporated in the detailed design.
2.6
Site
audits should be undertaken during the construction phase of the Project to
check that the proposed landscape and visual mitigation measures are properly
implemented and maintained as per their intended objectives. Site inspections should be undertaken by
the ET at least once every two weeks during the construction period.
2.7
In
the event of non-compliance, the responsibilities of the relevant parties are
detailed in the Event/Action plan provided on Table

3.1
Potential
air quality impact arising from the construction works would mainly be related
to construction dust from excavation, materials handling, spoil removal,
temporary stockpiles and wind erosion, as well as operation of barging
facilities. As construction dust is
the prime concern, monitoring should be carried out to evaluate the dust impact
during the construction phase. Total Suspended Particulates (
3.2
In
this section, the requirements, methodology, equipments, monitoring locations
and criteria for the monitoring and audit of air quality impact during the
construction phase of the Project are presented.
Monitoring Parameters and Equipment
3.3
24-hour
TSP levels should be measured to indicate the impacts of construction dust on
air quality, whilst, 1-hour TSP monitoring should be conducted only when
documented complaint was received.
The TSP levels should be measured by following the standard method as
set out in High Volume Method for Total Suspended Particulates, Part 50 Chapter
1 Appendix B, Title 40 of the Code of Federal Regulations of the USEPA
(hereinafter referred to as “HVS method”).
3.4
All
relevant data including temperature, pressure, weather conditions, elapsed-time
meter reading for the start and stop of sampler, identification and weight of
the filter paper, and other special phenomena and work progress of the
concerned site, etc, should be recorded down in detail. A sample data sheet is shown in Appendix B1.
3.5

3.6
The
ET shall be responsible for the provision of the monitoring equipment and
should provide sufficient number of HVSs or direct reading dust meters with
appropriate calibration kit for carrying out the baseline, regular impacts
monitoring and ad-hoc monitoring.
The HVSs should be equipped with an electronic mass flow controller and
be calibrated against a traceable standard at regular intervals, in accordance
with requirements stated in the manufacturers operating manual and as described
below. If direct reading dust meters is proposed to be used, the ET Leader
should submit sufficient information to the IEC to prove that the instrument is
capable of achieving a comparable result as that the HVS and may be used for
the 1-hour sampling. The instrument should also be calibrated regularly. All the equipment, calibration kit,
filter papers, etc, should be clearly labelled.
3.7
Initial
calibration of HVSs with mass flow controller should be conducted upon
installation and thereafter every six months. The transfer standard shall be
traceable to the internationally recognised primary standard and be calibrated
annually. The calibration data should be properly documented for future
reference by the IEC.
3.8
The
flow rates of the sampler before and after the sampling exercise with the
filter in position should be verified to be constant and be recorded on the
data sheet as shown in Appendix B1.
3.9
If
the ET Leader proposes alternative dust monitoring equipment / methodology
(e.g. direct reading methods) after the approval of this Manual, agreement from
the IEC should be sought. The instrument should also be calibrated regularly
following the requirements specified by the equipment manufacturers.
3.10
Wind
data monitoring equipment should also be provided and set up for logging wind
speed and wind direction near the dust monitoring locations. The equipment
installation location should be proposed by the ET and agreed with the IEC. For
installation and operation of wind data monitoring equipment, the following
points should be observed:
(i)
The
wind sensors should be installed 10m above ground so that they are clear of
obstructions or turbulence caused by buildings.
(ii)
The
wind data should be captured by a data logger. The data should be downloaded for
analysis at least once a month.
(iii)
The
wind data monitoring equipment should be re-calibrated at least once every six
months.
(iv)
Wind
direction should be divided into 16 sectors of 22.5 degrees each.
3.11
In
exceptional situations, the ET may propose alternative methods to obtain
representative wind data upon approval from the ER and agreement from the IEC.
Laboratory Measurement / Analysis
3.12
A
clean laboratory with constant temperature and humidity control, and equipped
with necessary measuring and conditioning instruments to handle the dust
samples collected, should be available for sample analysis, and equipment
calibration and maintenance. The laboratory should be HOKLAS accredited.
3.13
If
a site laboratory is set up or a non-HOKLAS accredited laboratory is hired for
carrying out the laboratory analysis, the laboratory equipment shall be
approved by the ER in consultation with the IEC. Measurement performed by the
laboratory shall be demonstrated to the satisfaction of the ER and the IEC. IEC
shall conduct regular audit to the measurement performed by the laboratory to
ensure the accuracy of measurement results. The ET Leader shall provide the ER
with one copy of the Title 40 of the Code of Federal Regulations, Chapter 1
(Part 50), Appendix B for his reference.
3.14
Filter
paper of size 8” x 10” should be labeled before sampling. It should be a clean
filter paper with no pinholes, and should be conditioned in a
humidity-controlled chamber for over 24-hours and be pre-weighed before use for
the sampling.
3.15
After
sampling, the filter paper loaded with dust should be kept in a clean and
tightly sealed plastic bag. The filter paper should then be returned to the
laboratory for reconditioning in the humidity-controlled chamber followed by
accurate weighing by an electronic balance with readout down to 0.1 mg. The
balance should be regularly calibrated against a traceable standard.
3.16
All
the collected samples should be kept in a good condition for 6 months before
disposal.
3.17
The
worst potentially affected locations in the vicinity of the construction
activities of the Project identified for dust monitoring are listed in Table
3.1 and shown in Figure No.
NEX2213/C/361/ENS/M62/510.

EM&A programme, the monitoring works would be taken up by this Project.
3.18
The
status and locations of air quality sensitive receivers (ASRs) may change after
approval of this Manual. In such case, the ET Leader should propose alternative
dust monitoring stations and seek agreement from the IEC and EPD.
3.19
If
alternative monitoring stations are proposed under the situation mentioned
above, these stations should be chosen based on the following criteria:
(i)
Monitoring at ASRs close to the major site
activities of the Project which are likely to cause air quality impacts;
(ii)
Monitoring as close as possible to the ASRs as
defined in the EIAO-TM; and
(iii)
Assurance of minimal disturbance to the occupants
and working under a safe condition during monitoring.
3.20
When
positioning the HVSs, the following points should be noted:
(i)
A horizontal platform with
appropriate support to secure the samplers against gusty wind should be
provided;
(ii)
Two samplers should not be placed less than 2m
apart;
(iii)
The distance between the sampler and an obstacle,
such as buildings, must be at least twice the height that the obstacle
protrudes above the sampler;
(iv)
A minimum of 2m separation from walls, parapets and
penthouses is required for rooftops samplers;
(v)
A minimum of 2m separation from any supporting
structures measured horizontally is required;
(vi)
No furnace or incinerator flue is located nearby
the samplers;
(vii)
Airflow around the sampler is unrestricted;
(viii)
The sampler is more than
(ix)
Any wire fence and gate to protect the sampler should
not cause any obstruction during monitoring;
(x)
Permission must be obtained to set up the samplers
and to obtain access to the monitoring stations; and
(xi)
A secured supply of electricity is needed to
operate the samplers.
3.21
In
case the baseline monitoring cannot be carried out at the designated monitoring
locations during the baseline monitoring period, the ET Leader shall carry out
the monitoring at alternative locations which can effectively represent the
baseline conditions at the impact monitoring locations. The alternative
baseline monitoring locations should be agreed with EPD prior to commencement
of baseline monitoring.
3.22
Baseline
monitoring should be carried out to determine the ambient 1-hour and 24‑hour
TSP levels at the monitoring stations prior to the commencement of the Project
works. Before commencing the baseline monitoring, the ET leader should inform
the IEC of the baseline monitoring programme such that the IEC can conduct
on-site audit to ensure accuracy of the baseline monitoring results.
3.23
TSP
baseline monitoring should be carried out for a continuous period of at least
two weeks with the 24-hour and three sets of 1-hour ambient measurements taken
daily at each monitoring station. During
the baseline monitoring, there should not be any construction or dust
generating activities in the vicinity of the monitoring stations. General
meteorological conditions (wind speed, direction and precipitation) and notes
regarding any significant adjacent dust producing sources should also be
recorded throughout the baseline monitoring period. A summary of baseline monitoring is
presented in Table 3.2.
3.24
In
exceptional cases, when insufficient baseline monitoring data or questionable
results are obtained, the ET Leader should liaise with the EPD to agree on an
appropriate set of data to be used as a baseline reference. A summary of
baseline monitoring is presented in Table 3.2.
3.25
The
baseline monitoring will provide data for the determination of the appropriate
Action levels whilst the Limit levels will be set against statutory or
otherwise agreed limits.
3.26
If
the ET Leader considers that significant changes in the ambient conditions have
arisen, a repeat of the baseline monitoring may be carried out to update the
baseline levels and air quality criteria, after consultation and agreement with
the ER, the IEC and the EPD.
3.27
The
monthly schedule of the impact monitoring programme should be drawn up by the
ET one month prior to the commencement of the scheduled construction
period.
3.28
For
the regular 24-hour TSP impact monitoring, a sampling frequency of at least
once in every six days should be strictly observed at the monitoring stations when there are Project related construction activities
being undertaken within a radius of 500m from these monitoring stations. The specific time
to start and stop the 24-hour TSP monitoring should be clearly defined for each
location and be strictly followed the field operator. For 1-hour TSP monitoring,
the sampling frequency of at least three times in every six-days should be
undertaken when the highest dust impact occurs. In case non-compliance with the air
quality criteria, more frequent monitoring, as specified in the Action Plan in
the following section, should be conducted. This additional monitoring should
be continued until the excessive dust emission or the deterioration in the air
quality is rectified. The impact
monitoring programme is summarised in Table 3.2.

3.32 As identified in the EIA Report, there would be no adverse air quality impact anticipated from the operation of the Project as the scheduled trains will be electrically operated. In terms of the Intercity and freight trains and maintenance locomotives, the mode of operation and frequency are the same as the prevailing condition, and no adverse air quality would be expected. Therefore, no specific environmental monitoring and audit requirements are required during operation phase.
3.33
Site
specific dust mitigation measures recommended in the EIA Report include watering
on active works areas, exposed areas and paved haul roads, enclosing the
unloading process at barging point, good site practices and dust suppression
measures stipulated in Air Pollution Control (Construction Dust) Regulation.
3.34
Other
site-specific mitigation measures recommended in the EIA Report are presented
in Appendix
A.
4.1
In this section, the
requirements, methodology, equipment, monitoring locations and protocols for
the monitoring and audit of airborne noise impacts during the construction and
operation phases of the Project are presented.
4.2
The construction noise level should be measured in terms of the
A-weighted equivalent continuous sound pressure level (Leq). Leq (30 minutes) should be
used as the monitoring parameter for the time period between 0700 and 1900
hours on normal weekdays.
4.3
Supplementary information for data auditing and statistical results such
as L10 and L90 should also be obtained for
reference. A sample data record
sheet is shown in Appendix B2 for reference.
Monitoring Equipment and Methodology
4.4
As referred to the requirements of the Technical Memorandum (TM) issued
under the NCO, sound level meters in compliance with the International
Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type
1) specifications should be used for carrying out the noise monitoring. Immediately prior to and following each
noise measurement the accuracy of the sound level meter should be checked using
an acoustic calibrator generating a known sound pressure level at a known
frequency. Measurements may be
accepted as valid only if the difference between calibration levels obtained
before and after the noise measurement is less than 1.0 dB.
4.5
Noise measurements should not be made in the presence of fog, rain, wind
with a steady speed exceeding 5ms-1 or wind with gusts exceeding
10ms-1. The wind speed should be checked with a portable wind speed
meter capable of measuring wind speeds in ms-1.
4.6
The ET is responsible for the provision of the monitoring equipment and
should ensure that sufficient noise measuring equipment and associated
instrumentation are available for carrying out the baseline monitoring, regular
impact monitoring and ad hoc
monitoring. All the equipment and
associated instrumentation should be clearly labelled.
4.7
In accordance with the EIA Report, the designated locations for
construction noise monitoring are listed in Table 4.1 and shown in Figure No. NEX2213/C/361/ENS/M62/520.

The status and location of noise sensitive receivers (NSRs) may change
after approval of this Manual. In
such case, and if changes to the monitoring locations are considered necessary,
the ET Leader should propose updated monitoring stations and seek approval from
the ER and agreement from the IEC and EPD on the proposal. If alternative monitoring stations are
proposed, these stations should be chosen based on the following criteria:
§
Monitoring at NSRs
close to the major site activities of the Project that are likely to cause
noise impacts;
§ Monitoring as close as possible to the NSRs as defined in the EIAO-TM;
and
§ Assurance of minimal disturbance to the occupants and working under a
safe condition during monitoring.
4.9
The monitoring stations should normally be at a point
4.10
The ET should carry out baseline noise monitoring prior to the
commencement of the construction works.
The baseline noise levels should be measured for a continuous period of
at least 14 consecutive days at a minimum logging interval of 30 minutes for
daytime (between 0700 and 1900 hours of normal weekdays) and 15 minutes (as
three consecutive Leq, (5 minutes) readings) for evening time
(between 1900 and 2300 hours on normal weekdays), general holidays including Sundays
(between 0700 and 2300 hours) and night-time (between 2300 and 0700 on all
days). The Leq, L10 and L90 should be recorded
at the specified interval. Before
commencing the baseline monitoring the ET leader should inform the IEC of the
baseline monitoring programme such that the IEC can conduct on-site audit to
ensure accuracy of the baseline monitoring results.
4.11
There should not be any construction activities in the vicinity of the
monitoring stations during the baseline monitoring. Any non-project related construction
activities in the vicinity of the monitoring stations during the baseline
monitoring should be noted and the source and location of such activities
should be recorded.
4.12
In exceptional cases, when baseline monitoring data obtained are insufficient
or questionable, the ET Leader should liaise with the IEC and EPD to agree on
an appropriate set of data to be used as the baseline reference.
4.13
Noise monitoring should be carried out at all the designated monitoring
stations when there are Project-related construction activities being
undertaken within a radius of 300m from the monitoring stations. The monitoring frequency should depend
on the scale of the construction activities. An initial guide on the monitoring is to
obtain one set of 30-minute measurement at each station between 0700 and 1900
hours on normal weekdays at a frequency of once a week when construction
activities are underway.
4.14
If a school is located near the construction activities, noise
monitoring should be carried out at the monitoring stations for the school
during school examination periods. The ET Leader should liaise with the school
administration and the Hong Kong Examinations and Assessment Authority to
ascertain the exact dates and times of all examinations during the construction
phase of the Project.
4.15
In the case of non-compliance with the construction noise criteria, more
frequent monitoring, as specified in Event and Action Plan in Table 4.3, should be carried out. This additional monitoring should be
continued until the recorded noise levels show that the non-compliance is
rectified or proved to be irrelevant to the Project-related construction
activities.
4.16
The
Action and Limit levels for construction noise are defined in Table 4.2. Should non-compliance of the
noise quality criteria occurs, actions in accordance with the Event and Action
Plan in Table 4.3 should be taken.
Table 4.2 Action and Limit
Levels for Construction Noise Impact Monitoring

When one documented complaint is received |
75 dB(A) for residential premises |
70 dB(A) for schools and 65 dB(A) during examination period |
4.17
To
account for cases in which ambient noise levels, as identified by baseline
monitoring, approach or exceed the stipulated Limit Levels prior to the
commencement of construction, a Maximum Acceptable Impact Level, which
incorporates the baseline noise levels and the identified construction noise
Limit Level, may be defined and agreed with the EPD. The amended level will be
greater than 75 dB(A) and will represent the maximum acceptable noise level at
a specific monitoring station. Correction factors for the effects of acoustic
screening and/or architectural features of NSRs may also be applied as
specified in the Technical Memorandum on Noise from Construction Work other
than Percussive Piling (GW-TM).

Operation Noise – Rail Operation
4.18
To
ensure compliance of operational airborne rail noise levels with the noise
standards stipulated in the NCO, the ET should carry out rail noise monitoring
at the potentially worst affected NSRs identified in the EIA Report upon
commencement of operation of the Project.
Operation Rail Noise Monitoring
4.19
Monitoring of LAeq 30min
train noise levels will be carried out at the proposed monitoring locations
during night-time period, i.e.2300-0700 on a monthly basis after the entire SCL Hung
Hom to Admiralty section is in operation. Background noise levels shall also be
measured. It is recommended to
conduct the monitoring for the initial start-up of up to 6 months. With full compliance of the noise limit
and agreement from IEC, monitoring can be terminated before the end of this
6-month period.
Monitoring Equipment and Methodology
4.20
The monitoring equipments and methodology for operation rail noise
monitoring should be same as those recommended for construction airborne noise
monitoring.
4.21
Based on the EIA study, the potentially worst affected locations were
designated for operational airborne noise monitoring as listed in Table 4.4 and illustrated in Figure
No. NEX2213/C/361/ENS/M62/521.

The status and location of noise monitoring stations may change after
approval of this Manual. In such
cases, and if changes to the monitoring locations are considered necessary, the
ET Leader should propose updated monitoring stations and seek agreement from
the IEC and EPD on the proposal. If
alternative monitoring locations are proposed, the monitoring locations should
be chosen based on the following criteria:
§
Monitoring at NSRs close
to the Project railway which are likely to cause noise impacts;
§ Monitoring as close as practicable to the NSRs as defined in the EIAO-TM
and IND-TM; and
§ Assurance of minimal disturbance to the occupants and working under a
safe condition during monitoring.
4.23
The monitoring stations should normally be at a point
Maximum Permissible Sound Power Levels of Fixed Plant
4.24
The
maximum permissible sound power levels of the identified fixed noise sources of
the Project were predicted in the EIA report. To ensure that the noise impact
associated with the fixed plant operations would comply with the noise
standards stipulated in the EIAO-TM and NCO, the specified sound power levels
should be implemented and refined by the Contractor as appropriate. No specific
monitoring for the fixed plant operation is deemed necessary.
4.25
The
EIA report indicates that construction activities would cause noise exceedances
at a few NSRs, and therefore, appropriate mitigation measures and good site
practices are recommended. The Contractor should be responsible for the design
and implementation of these measures. The implementation schedule for the
recommended mitigation measures is presented in Appendix A.
4.26
In
the event of exceedances or complaints, the Contractor should review the
effectiveness of these mitigation measures and propose, design and implement
alternative or additional measures as appropriate. The Contractor should liaise with the ET
Leader on alternative or additional mitigation measures submit to the ER for
approval and implement the mitigation measures.
4.27
The
mitigation measures as recommended in the EIA Report for the operation of the
Project is presented in Appendix A. These measures should be reviewed and
refined by the ER and ET Leader if there are any major design changes during
the detailed design phase such that the recommended measures are adequate for
alleviating the potential operation rail noise impacts.
5.1
In this section, the requirements for the monitoring and audit of
ground-borne noise impacts during the construction and operation phases of the
Project are presented.
Construction Ground-borne Noise
5.2
In accordance with the EIA Report, the
predicted construction ground-borne noise level at the identified ground-borne
NSR would comply with the noise criteria.
Adverse ground-borne construction noise impact due to the Project would
not be envisaged. Environmental monitoring is thus considered not necessary during
construction phase.
5.3
According to the requirements of the
Technical Memorandum (TM) issued under the NCO, sound level meters in compliance
with the International Electrotechnical Commission Publications 651:1979 (Type
1) and 804:1985 (Type 1) specifications should be used for carrying out the
noise monitoring. Immediately prior to and following each noise measurement,
the accuracy of the sound level meter should be checked using an acoustic
calibrator generating a known sound pressure level at a known frequency.
Measurements may be accepted as valid only if the different between the
calibration levels obtained before and after the noise measurement is less than
1.0 dB.
5.4
A commissioning test should be conducted by the ET before the entire SCL Hung
Hom to Admiralty section is in operation to check the compliance of the operational
ground-borne noise levels with the NCO noise criteria. The ground-borne noise monitoring
location should include the critical NSR stated in Table 5.1 and in Figure NEX2213/C/361/ENS/M62/521. The noise commissioning test report should
be submitted to the IEC for verification.

5.5
The monitoring location shall normally be at the lowest sensitive floor of
each designated monitoring location and normally be at a position 1.2m above
ground inside the building structures. It shall also not be significantly
affected by background noise level. The exact location for the monitoring shall
be proposed by the ET and agreed with IEC and EPD.
5.6
If there is problem with access to the normal monitoring position, an
alternative position may be chosen and a correction to the measurements shall
be made. The ET shall agree with the IEC on the monitoring position and the corrections
adopted. Once the positions for the monitoring stations are chosen, the
baseline and the impact monitoring shall be carried out at the same
position. If changes to the monitoring stations are required
upon commencing the baseline monitoring or thereafter, the ET should propose
alternative locations based on the above-mentioned criteria and seek approval
from the ER and agreement from the IEC and EPD on the proposal.
5.8
The predicted
operational ground-borne noise at all identified NSRs would comply with the
noise criteria. Mitigation measures
are not required.
6.1
In
accordance with the EIA Report, with recommended mitigation measures properly
in place, no adverse water quality is expected during the construction and
operation phases of the Project and no water quality monitoring is hence
proposed. However, regular
inspections of the construction activities and works areas should be conducted
during the construction phase to ensure proper implementation of the
recommended mitigation measures.
6.2
No
surface water quality monitoring would be required during the construction
phase. To avoid potential water
quality impact arising from construction activities, regular site audit should
be conducted to ensure the recommended mitigation measures are properly
implemented.
6.3
Implementation
of regular site audits is to ensure that the recommended mitigation measures
are to be properly undertaken during construction phase of the Project. It can
also provide an effective control of any malpractices and therefore achieve
continual improvement of environmental performance on site. Site audits
should include site inspections and compliance audits.
6.4
The
requirements of the environmental audit programme are set out in Section 9 of this Manual. The audit programme will verify the
implementation status and evaluate the effectiveness of the mitigation
measures.
Site
Inspection
6.6
Site
audits should be carried out by the ER, ET and Contractor and should be based
on the mitigation measures for water pollution control recommended in Appendix A. In the event that the recommended
mitigation measures are not fully or properly implemented, the Contractor
should record the deficiency and report to the ER and ET. Suitable actions are to be carried out
by the Contractor to:
§ investigate the
problems and the causes;
§ discuss a remedial
and corrective proposal with the ER and ET;
§ take action according
to action notes agreed with the ER;
§ implement remedial
and corrective actions immediately;
§ re-inspect the site
conditions upon completion of the remedial and corrective actions; and
§ record the event and
discuss with the ER and ET for preventive actions.
Compliance
Audits
6.7
Compliance
audits are to be undertaken by the ER and ET to ensure that a valid discharge
license has been issued by the EPD prior to the discharge of effluent from the
construction activities of the Project site. If monitoring of the treated
effluent quality from the works areas is required during the construction phase
of the Project, the monitoring should be carried out in accordance with the Water Pollution Control Ordinance (WPCO)
license which is under the ambit of the regional office (RO) of EPD. The audit
results reflect whether the effluent quality is in compliance with the discharge
license requirements. In case of non-compliance, suitable actions should be
undertaken:
§ The ET should notify
the Contractor, IEC and ER;
§ The Contractor should
identify the sources of pollution and recommend the appropriate mitigation
measures to be agreed by the ER and ET;
§ The ER and ET should
check the implementation status of the agreed mitigation measures;
§ The ER and ET should
investigate the operating conditions of the on-site treatment systems;
§ The Contractor should
implement corrective and remedial actions to improve the effluent quality;
§ The ET should
increase monitoring frequency until the effluent quality is in compliance with
the discharge license requirements; and
§ The ET should record
the non-compliances and propose preventive measures.
6.8
Water
quality monitoring and audit is not required during the operation phase as no
adverse water quality impact would be anticipated during the operation phase,
provided that all mitigation measures recommended in the EIA Report are properly
implemented.
6.9
The
recommended mitigation measures for water quality impacts during construction
stage are presented in the Implementation Schedule in Appendix A.
6.10
In
the event of complaints, or non-compliance / area of improvement being
observed, the ET and Contractor should review the effectiveness of these
mitigation measures, design alternative or additional mitigation measures as
appropriate and propose to the ER for approval, and implement these alternative
or additional measures accordingly.
7.1
Construction
and Demolition (C&D) materials, sediment, general refuse from workforce and
chemical waste would be generated during the construction phase of the Project.
It is the Contractor’s responsibility to ensure all the waste arisen from the
Project are handled, stored and disposed of in accordance with good waste
management practices, relevant legislation and waste management guidelines.
Provided that these wastes are handled, transported and disposed of using
approved methods and that the recommended good site practices are strictly
followed, adverse environmental impacts would not be expected.
7.2
Large
quantities of waste are not expected to be generated from the operation of the
Project and no adverse environmental impacts will arise with the implementation
of good waste management practices. Therefore, an audit programme for the
operational phase of the Project will not be required.
7.3
Regular
audits and site inspections should be carried out during construction phase by
the ER, ET and Contractor to ensure that the recommended good site practices
and mitigation measures in Appendix A are properly implemented by the
Contractor. The audits should concern all aspects of on-site waste management
practices including waste generation, storage, recycling, transport and
disposal. Apart from site inspections,
documents including licences, permits, disposal and recycling records should be
reviewed and audited for compliance with the legislation and contract
requirements.
7.4
The
requirements of the environmental audit programme are set out in Section 9 of this Manual. The audit programme will verify the
implementation status and evaluate the effectiveness of the mitigation
measures.
Construction Phase
7.5
The mitigation measures recommended in
the EIA Report should form the basis of the site Waste Management Plan (WMP) to
be developed by the Contractor during the construction stage.
7.6
It is recommended that the waste
materials generated during the construction activities should be audited
regularly by the ET to determine if wastes are being managed in accordance with
approved procedures and the site WMP.
The audit should look at all aspects of on-site waste management
practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, documents
including licences, permits, disposal and recycling records should be reviewed
and audited for compliance with the legislation and contract requirements. In addition, the routine site
inspections should check the implementation of the recommended good site practices
and other waste management mitigation measures.
7.7
With
the appropriate handling, storage and disposal of waste arising from the
construction works as recommended in Appendix A, the potential of adverse
environmental impacts would be minimized.
During the site inspections, the ET should pay special attention to the
issues relating to the waste management and check whether the Contractor has
implemented the recommended good site practices and mitigation measures.
Operation Phase
7.8
The anticipated
volume of waste generation in operation phase is insignificant. But mitigation measures as recommended
in Appendix
A are implemented for the identified waste types in order to minimise the
potential impacts to the environment.
8.1
The
land contamination assessment has examined the potential contaminating land
uses within the Project area and investigated the potential impacts of the
contamination on future use. Based on the findings from the Stage 1, Post-Stage
1 and Stage 2 site investigation (SI), no adverse impacts have been identified
within the Project area. No specific EM&A requirement is therefore
required. Precautionary measures are proposed for the excavation of soil,
treatment of soil and general environmental impacts, together with health and
safety measures on site during the construction stage.
8.2
With
implementation of recommendations for land contamination in the EIA Report, specific
EM&A requirement is not required.
8.3
Mitigation
measures for land contamination have been recommended in the EIA Report. The Contractor should be responsible for
the implementation of these measures. The implementation schedule of the
recommended land contamination mitigation measures is presented in Appendix A.
9.1
Site inspection is
one of the most effective tools to enforce the environmental protection
requirements at the works area by providing a direct mean to trigger and
enforce specified environmental protection and pollution control measures. Site
inspections should be undertaken regularly during the construction phase to
ensure that appropriate environmental protection and pollution control
mitigation measures are properly implemented for the activities associated with
the Project.
9.2
The ET should be
responsible for formulating the environmental site inspection programme as well
as the deficiency and remedial action reporting system, and for carrying out
the site inspections. The proposal
for rectification, if any, should be prepared and submitted to the ET Leader
and IEC by the Contractor.
9.3
Regular
site inspections should be carried out and led by the
ER and attended by the Contractor and ET at least once per week during the
construction phase. The areas of inspection should not be limited to the
environmental conditions and the pollution control and mitigation measures
within the works areas. It should also review the environmental conditions of
locations that are beyond the boundary of the works areas but are likely to be
affected directly or indirectly by the construction site activities of the
Project. During the inspection, the
following information should be referred to:
§
The EIA report and
EM&A Manual recommendations on environmental protection and pollution
control mitigation measures;
§ Ongoing results of the EM&A programme;
§ Works progress and programme;
§ Individual works methodology proposals (which should include the
proposal on associated pollution control measures);
§ Contract specifications on environmental protection and pollution
prevention control;
§ Relevant environmental protection and pollution control legislations;
and
§ Previous site inspection results undertaken by the ET and others.
9.4
The
Contractor should keep the ER and ET Leader updated with all relevant
environmental related information on the construction contract necessary for
him/her to carry out the site inspections.
Site inspection results and associated recommendations for improvements
to the environmental protection and pollution control efforts should be
recorded and followed up by the Contractor in an agreed time-frame. The Contractor should
follow the procedures and time-frame stipulated in the environmental site
inspection, and the deficiency and remedial action reporting system to be
formulated by the ET Leader, to report on any remedial measures subsequent to
the site inspections.
9.5
The ER, ET and the
Contractor should also carry out ad hoc site inspections 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 the Event and Action Plan
for the EM&A programme.
9.6
There
are statutory requirements on environmental protection and pollution control,
with which construction activities must comply.
9.7
To
ensure the works are in compliance with all method statements of works should
be submitted by the Contractor to the ER for approval and to the ET Leader to
determine if sufficient environmental protection and pollution control measures
have been included. The
implementation schedule of mitigation measures is summarized in Appendix A. Any proposed changes to the mitigation
measures shall be certified by the ET Leader and verified by the IEC as conforming
to the relevant information and recommendations contained in the EIA Report.
9.8
The
ER and ET Leader should also review the progress and programme of the works to
check that relevant environmental legislations have not been violated, and that
any foreseeable potential for violating laws can be prevented.
9.9
The
Contractor should provide the update of the relevant documents to the ET Leader
so that works checking could be carried out effectively. The document
should at least include the updated Works Progress Reports, updated Works
Programme, method statements, any application letters for licences / permits
under the environmental protection legislations, and copies of all valid
licences / permits. The site diary
and environmental records should also be available for the inspection by the
relevant parties.
9.10
After
reviewing the documentation, the ET Leader should advise the Contractor of any
non-compliance with legislative requirements on environmental protection and
pollution control so that they can timely take follow-up actions as
appropriate. If the follow-up
actions may still result in violation of environmental protection and pollution
control requirements, the ER and ET should provide further advice to the
Contractor to take remedial action to resolve the problem.
9.11
Upon
receipt of the advice, the Contractor should undertake immediate action to
remedy the situation. The ER and ET
should follow up to ensure that appropriate action has been taken in order to
satisfy legal requirements.
9.12 At times during
the construction phase the Contractor may submit method statements for various
aspects of construction. This state of affairs would only apply to those
construction methods that the EIA has not imposed conditions while for
construction methods that have been assessed in the EIA, the Contractor is
bound to follow the requirements and recommendations in the EIA study. The
Contractor’s options for alternative construction methods may introduce adverse
environmental impacts into the Project. It is the responsibility of the
Contractor and ET, in accordance with established standards, guidelines and EIA
study recommendations and requirements, to review and determine the adequacy of
the environmental protection and pollution control measures in the Contractor’s
proposal in order to ensure no unacceptable impacts would result. To achieve
this end, the ET shall provide a copy of the Proactive Environmental Protection
Proforma as shown in Appendix B3 to the IEC for approval. The IEC should audit the review
of the construction method and endorse the proposal on the basis of no adverse
environmental impacts.
9.12
The
following procedures should be undertaken upon receipt of any environmental
complaint:
i. The Contractor to log complaint and date of receipt onto the complaint database and inform
the ER, ET and IEC immediately;
ii. The Contractor to investigate, with the ER and ET, the complaint to
determine its validity, and assess whether the source of the problem is due to
construction works of the Project with the support of additional monitoring
frequency and stations, if necessary;
iii. The Contractor to identify remedial measures in consultation with the IEC,
ET and ER if a complaint is valid and due to the construction works of the
Project;
iv. The Contractor to implement the remedial measures by the ER and to agree
with the ET and IEC any additional monitoring frequency and stations, where
necessary, for checking the effectiveness of the remedial measures;
v. The ER, ET and IEC to review the effectiveness of the Contractor's
mitigation measures, and the updated situation;
vi. The ET/Contractor to undertake additional monitoring and audit to verify
the situation if necessary, and oversee that circumstances leading to the

Final EM&A Review
Report - Construction Phase
10.9
The EM&A
programme should be terminated upon the completion of the construction
activities that have the potential to result in significant environmental
impacts.
10.10
Prior to the proposed
termination, it may be advisable to consult relevant local communities. The proposed termination should only be
implemented after the proposal has been endorsed by the IEC, the Engineer and
the Project Proponent followed by approval from the Director of Environmental
Protection.
10.11 The ET Leader should prepare and submit the Final EM&A Report which
should contain at least the following information:
(i) executive
summary (1 - 2 pages);
(ii) drawings showing the project
area, environmental sensitive receivers and locations of the monitoring and
control stations;
(iii) basic project
information including a synopsis of the project organisation, contacts of key
management, and a synopsis of works undertaken during the course of the
Project;
(iv) a
brief summary of EM&A requirements including:
environmental mitigation measures, as recommended in the EIA Report;
environmental
impact hypotheses tested;
environmental
quality performance limits (Action and Limit levels);
all
monitoring parameters; and
Event
and Action Plans;
(v) a summary of the
implementation status of environmental protection and pollution control /
mitigation measures, as recommended in the EIA Report, summarised in the
updated implementation schedule;
(vi) graphical plots and the
statistical analysis of the trends of monitoring parameters over the course of
the project, including the post-project monitoring for all monitoring stations
annotated against:
the major activities being carried out on site during the reporting
period;
weather
conditions during the reporting period; and
any
other factors which might affect the monitoring results;
(vii) a summary of
non-compliance (exceedances) of the environmental quality performance limits
(Action and Limit levels);
(viii) a review of the reasons
for and the implications of non-compliance including review of pollution
sources and working procedures as appropriate;
(ix) a description of the actions
taken in the event of non-compliance;
(x) a summary record of all
complaints received (written or verbal) for each media, liaison and
consultation undertaken, actions and follow-up procedures taken;
(xi) a summary record of
notifications of summons and successful prosecutions for breaches of the
current environmental protection / pollution control legislation, locations and
nature of the breaches, investigation follow-up actions taken and results;
(xii) a review of the
validity of EIA predictions and identification of shortcomings of the
recommendations proposed in EIA Report;
(xiii) comments (for example,
a review of the effectiveness and efficiency of the mitigation measures and of
the performance of the environmental management system, that is, of the overall
EM&A programme); and
(xiv) recommendations and
conclusions (for example, a review of success of the overall EM&A programme
to cost-effectively identify deterioration and to initiate prompt effective
mitigation action when necessary).
10.12 No site-based documents
(such as monitoring field records, laboratory analysis records, site inspection
forms, etc.) are required to be included in the EM&A reporting
documents. However, any such document should be properly maintained by
the ET and be ready for inspection upon request. All relevant information
should be clearly and systematically recorded in the document. Monitoring
data should also be recorded in magnetic media form, and the software copy must
be available upon request. All documents and data should be kept for at least
one year following the completion of the construction phase EM&A for each
construction contract.
10.13
A dedicated internet web-site will be set up for
reporting the EM&A data for public inspection in real-time. Real-time
reporting in this context refers to the posting of monitoring data after it has
been through the appropriate processing, QA/QC checking by the ET and
validation by the IEC.
Interim Notifications of Environmental
Quality Limit Exceedances
10.14 With reference to the
Event and Action Plans, when the environmental quality performance limits are
exceeded and if they are proven to be valid, the ET should immediately notify
the IEC and EPD, as appropriate.
The notification should be followed up with advice to the IEC and EPD on
the results of the investigation, proposed actions and success of the actions
taken, with any necessary follow-up proposals. A sample template for the interim
notification is presented in Appendix C.
