Introduction
1.1.1
The title of the Project is “Improvement to So Kwun Po
Interchange” (hereafter referred to as the Project).
1.1.2
The So Kwun Po Interchange (SKPIC) is one of the three
major interchanges in the North District connecting the northern and southern
parts of Fanling and Sheung Shui. The SKPIC has been operating close to
its capacity. The SKPIC was allegedly one of the causes of several
numbers of serious traffic gridlocks in the North District in the past few
years.
1.1.3
Media reports had also suggested that the series of
traffic incidents that occurred in January 2016, which paralysed and stranded
the District’s external traffic links, was partly due to the traffic gridlock
and overcapacity at the Kai Leng Roundabout and other road junctions in the
District. The traffic chaos that appeared in these incidents also
highlighted the fragility and deficiencies of existing transport infrastructure
at some locations in the District where upgrading and/or improvement works are
necessary to rectify the situation. The North District Council (NDC) had
made requests to the Government for its improvements on various occasions.
With the anticipated population increase in the North District following
the completion of public and private housing developments which are under
planning, the traffic condition at the SKPIC is expected to deteriorate
further.
1.1.4
In order to meet anticipated traffic needs and to
address public demands, a new road link and junction modification works would
be carried out to improve the existing SKPIC.
1.1.5
To address the above congestion problem, the Traffic
and Transport Committee of NDC has earlier proposed a new North to South Link
in an attempt to mitigate the current traffic situation.
1.2

General Requirements of THE EM&A Programme
2.1.1
General requirements of the EM&A programme for the
Project are presented in this section. The scope of the programme is
developed with reference to the findings and recommendations of the EIA Report.
2.2
Objectives of the EM&A Programme
2.2.1
The potential environmental impacts associated with the
Project have been assessed and described in the EIA Report. The EIA
Report also specifies the mitigation measures required to comply with the
environmental criteria. These mitigation measures and their
implementation requirements are presented in the Implementation Schedule (refer
to Appendix 1.2). The EIA recommends that an EM&A programme be
implemented to assess the effectiveness of measures and to confirm that there
will be no adverse environmental impacts during all phases of the
Project. It is also recommended that regular site audits be undertaken
during the construction and operation phases to check whether good site
practices are properly implemented to prevent adverse environmental
impacts. Any activities that have the potential to cause adverse
environmental impacts are identified before the adverse impacts occur.
Ad-hoc visits should also be undertaken in response to any complaints or reported
non-compliance with environmental standards in order to enable prompt actions
to be taken to address the impacts.
2.2.2
This Manual provides details of the EM&A
requirements that have been recommended in the EIA Report. The main
objectives of the EM&A programme are to:
·
Verify the environmental impacts predicted in the EIA Report;
·
Monitor the performance of the Project and the effectiveness of
mitigation measures;
·
Determine Project compliance with regulatory requirements and standards;
·
Provide an early indication should any of the environmental control
measures or practices fail to achieve the required standards;
·
Take remedial action if unexpected problems or unacceptable impacts
arise;
·
Provide a database against which any short-term or long-term
environmental impacts of the Project can be determined; and
·
Provide data against which environmental audits may be undertaken.
2.3
Scope of the EM&A Programme
2.3.1
The scope of the EM&A Programme is to:
·
Establish baseline noise levels at
designated locations;
·
Implement impact monitoring
programmes for construction noise;
·
Implement inspection and audit
programmes for air quality, noise, water quality, waste management, ecology,
landscape and visual and cultural heritage issues;
·
Liaise with, and provide
environmental advice (as requested or when otherwise necessary) to construction
site staff on the comprehension and consequences of the environmental
monitoring data and exceedances;
·
Identify and resolve environmental
issues and other functions as they may arise from the works;
·
Check and advice the Contractor's
overall environmental performance, the implementation of EAPs, and remedial
actions taken to mitigate adverse environmental impacts as they may arise from
the works;
·
Conduct monthly reviews of
monitored impact data as the basis for assessing compliance with the defined
criteria and to ensure that necessary mitigation measures are identified and
implemented, and undertake additional ad hoc monitoring and auditing as
required by special circumstances;
·
Evaluate and interpret all
environmental monitoring data to provide an early indication should any of the
environmental control measures or practices fail to achieve the acceptable
standards, and to verify the environmental impacts assessed in the EIA Study;
·
Manage and liaise with other
individuals or parties concerning other environmental issues deemed to be
relevant to the construction process;
·
Conduct regular site inspections to
assess:
o The level of the Contractor’s general environmental awareness;
o The Contractor’s implementation of the recommendations in
the EIA Report;
o The Contractor’s performance as measured by the EM&A
programme;
o The need for specific mitigation measures to be implemented
or the continued usage of those previously agreed;
o To advise the Site Staff of any identified potential
environmental issues; and
·
Submit Monthly EM&A Reports
which summarise environmental monitoring and auditing data, with full
interpretation illustrating the acceptability or otherwise of any environmental
impacts and identification or assessment of the implementation status of agreed
mitigation measures.
2.4
Methodology and Criteria
2.4.1
The environmental issues associated with the construction
phase of the Project will be mitigated through the monitoring and mitigation
measures specified in the EIA Report and this EM&A Manual.
2.4.2
The monitoring of the effectiveness of the mitigation
measures will be achieved through the environmental monitoring programme as
well as through site inspections. The inspections will include within
scope, mechanisms to review and assess the implementation of the recommended
mitigation measures, and that the timely resolutions of received complaints are
managed and controlled in a manner consistent with the recommendations given in
the EIA Report and the EM&A Manual.
2.5
Environmental Monitoring
2.5.1
The environmental monitoring works throughout the
construction period and the first year after the commencement of operation of
the Project should be carried out in accordance with the EM&A Manual and
reported by the ET. Monitoring should be conducted at the chosen and
agreed representative sensitive receivers.
2.6
Action and Limit (A/L) Levels
2.6.1
Action and Limit (A/L) Levels are defined levels for
impact recorded by the environmental monitoring works, which represent levels
at which a prescribed response is required. These levels are described in
the principle below and later quantitatively defined in the relevant sections
of the EM&A Manual:
·
Action Level – beyond which there is a clear indication
of a deteriorating ambient environment for which appropriate remedial actions
are likely to be necessary to prevent environmental quality from falling
outside the Limit Levels, which will be unacceptable.
·
Limit Level – statutory limits stipulated in the
relevant pollution control ordinances, EIAO-TM, or Environmental Quality
Objectives established by the EPD. If these are exceeded, works should
not proceed without appropriate remedial action, including a critical review of
the plant and working methods.
2.7
Event and Action Plans
2.7.1
The purpose of the EAPs is to provide, in association
with the environmental monitoring activities, procedures for ensuring that if
any significant environmental impacts occur in the form of exceedance of A/L
Levels identified in the EM&A programme, cause(s) will be quickly
identified and remediated.
2.8.1
The ET should undertake the environmental audit of
compliance with stipulated procedures and site inspections of on-site
practices. The primary objective is to assess the effectiveness of the
implementation of the environmental mitigation measures as recommended in the
EIA Report and the EM&A Manual.
2.8.2
Whilst the environmental audit will complement the
environmental monitoring activity with regard to the effectiveness of dust
suppression and noise attenuation, the criteria against which the audit should
be derived from the clauses within the Contract, which seek to enforce the
recommendations of the EIA Report and the EM&A Manual.
2.8.3
The findings of the environmental audit and site
inspection should be made known to the Contractor at the time of the
audit/inspection to enable rapid resolution of identified non-compliances or
observations. Non-compliances, observations and the corrective/ follow-up
actions undertaken will be reported in the Monthly EM&A Reports.
2.9
Enquiries, Complaints and Requests for Information
2.9.1
Enquiries, complaints and requests for information will
be expected from a wide range of individuals and organisations including
members of the public, government departments, nearby residents, the press and
community groups.
2.9.2
All enquiries concerning the environmental effects of
the construction works, irrespective of the channel of receipt, will be
directed to the Contractor and copied to the ER and CEDD. Procedures
for handling enquiries and complaints should follow the procedures set out
in Section 11.
2.9.3
In all cases, the complainant should be notified of the
findings, and an environmental audit and site inspection should be put in place
to minimise the reoccurrence of similar problems.
2.10.1
During the construction phase, Environmental Baseline
Monitoring Reports, Monthly EM&A Reports and Final EM&A Review Reports
should be prepared and certified by the ET Leader and verified by IEC prior to
submission to the Contractor and CEDD. In accordance with Annex 21 of
the EIAO-TM, a copy of the monthly EM&A reports and final EM&A
review reports should be made available to the Director of Environmental
Protection. Details of the reporting requirements and submission schedule
should be in accordance with the guidelines set out in Section 12.
2.11 Change or Cessation of the EM&A Programme
2.11.1
The ET should carry out the EM&A programme in
accordance with the EM&A Manual throughout the construction and operation
phases of the Project. Any change or cessation of the EM&A
programme, or any part of it, should be justified by the ET Leader and verified
by the IEC as conforming to the requirements set out in the EM&A Manual and
should be submitted to the EPD for approval.
3
AIR QUALITY
3.1.1
Potential air quality impacts arising from the construction
and operation phases of the Project on air sensitive receivers (ASRs) were
addressed in the EIA Report. It is concluded that no adverse air quality
impact from the Project would be anticipated during the construction phase.
Dust monitoring is proposed to be conducted during the construction
phase of the Project.
3.1.2
No adverse air quality impact arising would be
anticipated during the operation phase of the Project. No operation phase
air quality monitoring and audit are therefore considered necessary.
3.1.3
Regular environmental site audit is recommended to be
conducted during the entire construction phase of the Project to ensure proper
implementation of the proposed dust mitigation measures and good site practices
stipulated in the Air Pollution Control (Construction Dust) Regulation
and those recommended in Section 3.9 of the EIA Report. The
implementation schedule of mitigation measures is presented in Appendix 1.2.
3.2
Monitoring Parameters
3.2.1
Monitoring of the Respirable Suspended Particulates
(RSP) and Fine Suspended Particulates (FSP) shall be carried out by the ET to
ensure that construction works are not generating dust that exceeds the
acceptable levels. The monitoring of RSP and FSP levels shall be carried
out continuously with logging of hourly data throughout the construction
phase.
3.3.1
A particulate matter (PM) monitoring equipment
(hereafter referred to as “the Sensor”) capable of performing continuous RSP
and FSP monitoring with logging of hourly data should be used. The model
of the Sensors to be used shall be proposed by the ET and agreed with the IEC
and ER.
3.3.2
The ET is responsible for the provision, installation,
operation, maintenance, and dismantling of the Sensors. The ET shall
ensure that a sufficient number of Sensors are available for carrying out the
continuous RSP and FSP monitoring.
3.3.3
The Sensors shall be calibrated on-site
regularly. The on-site calibration shall be done using Transfer Standard
(TS) Collocation. A TS is another PM monitor that is at least as capable
as the sensor to be calibrated.
On-site Calibration Requirements and Procedures
3.3.4
Another Sensor that has just been calibrated may serve
the purpose provided its performance is known to be stable during the
collocation period to be used as TS. The TS should be placed
near (<1 m if practicable) the Sensor to be calibrated so that both devices
would be monitoring a similar environment. The TS is then turned on to
warm-up for 30–60 minutes. The collocation period starts after the
warm-up and TS is then left running with the Sensor to be calibrated for at
least three hours. The measurements from the Sensor to be calibrated and
the TS during the collocation period will be statistically analysed. The
collocation period should be at least seven days.
3.3.5
Right before each on-site calibration, the TS itself
needs to be calibrated e.g. collocating with a PM reference monitor, such as
USEPA’s Federal Reference Method (FRM) or Federal Equipvalent Method (FEM) PM
monitor at EPD’s Air Quality Monitoring Station (AQMS) or research institutes
that has been calibrated against traceable standard.
3.3.6
The response of the Sensor should be adjusted if its
performance during on-site calibration does not meet the following evaluation
criteria. For each Sensor, data below its detection limit will be
excluded.
·
Tier 1: Correlation –
The minute average measurements from the Sensor and TS when subject to linear
regression should have a coefficient of determination (R2) > 0.7. The
regression line slope should be between 0.75 to 1.25. If these criteria
are not met due to narrow range of PM concentration (30 μg/m3
as recommended range) during the collocation period, Tier 2 will apply.
·
Tier 2: Root Mean squared error – The root mean squared error of the Sensor minute average
measurements should be <8 μg/m3.
3.3.7
Each deployed Sensor should be calibrated every month.
If a Sensor repeatedly failed in 2 or 3 consecutive calibrations, the
Sensor should be checked and maintained to improve its performance or it should
be replaced.
3.4.1
The selected monitoring locations are considered the
worst potentially affected air sensitive receivers located in the vicinity of
construction sites. The proposed air quality monitoring locations during
the construction phase are listed in Table 3.1 below and shown
in Figure 3.1.

3.7.1
Mitigation measures for construction phase air quality
impact have been recommended in the EIA Report. All recommended
mitigation measures are detailed in the implementation schedule presented
in Appendix
1.2. The Contractor shall be responsible
for the design and implementation of these measures.
3.8.1
Regular environmental site inspections and audits at
least once per week should be conducted during the entire construction phase of
the Project to ensure the recommended mitigation measures are properly
implemented. The audit programme serves to verify and keep track of the
implementation status of the recommended mitigation measures and the
effectiveness of these mitigation measures.
4
NOISE
4.1.1
The potential construction noise impact and road
traffic noise impact during the operation of the Project have been assessed in
the EIA.
4.1.2
Recommendations on construction noise mitigation
measures have been given in the EIA to mitigate the noise impact. A noise
monitoring and audit programme is recommended to be undertaken to confirm the
proposed mitigation measures have been implemented properly.
4.1.3
For road traffic noise impact, mitigation measures
including the provision of low-noise road surfacing and noise barriers have
been recommended to be implemented along some of the Project Roads. Road
traffic noise levels should be monitored at representative Noise Sensitive
Receivers (NSRs), which are in the vicinity of the recommended direct mitigation
measures, during the first year after road opening. The purpose of the
monitoring is to ascertain that the recommended mitigation measures are
effective in mitigating the noise impacts.
4.1.4
In this section, the requirements, methodology, equipment,
monitoring locations, criteria and protocols for the monitoring and audit of
noise impacts during the construction phase and operation phase of the Project
are presented.
4.2
General Monitoring Requirement
4.2.1
With reference to the Technical Memorandum (TM)
issued under the Noise Control Ordinance (NCO), sound level meters in
compliance with the International Electrotechnical Commission Publications
651:1979 (Type 1) and 804:1985 (Type 1) specifications shall be used for
carrying out the noise monitoring. The accuracy of the sound level meter
shall be checked using an acoustic calibrator generating a known sound pressure
level at a known frequency, immediately prior to and following each noise
measurement. Measurements shall be accepted as valid only if the
calibration level from before and after the noise measurement agrees to be
within 1.0dB(A).
4.2.2
Noise measurements shall not be made in fog, rain, wind
with a steady speed exceeding 5m/s or wind with gusts exceeding 10m/s.
The wind speed shall be checked with a portable wind speed meter capable
of measuring the wind speed in m/s.
4.2.3
The ET is responsible for the provision of the
monitoring equipment. The ET shall 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 shall be clearly labelled.
The location of equipment installation shall be proposed by the ET Leader
and agreed with the IEC and EPD.
4.2.4
The noise monitoring station shall normally be at a
point 1m from the exterior of the sensitive receiver building façade and be a
position of 1.2m above ground. If there is a problem with access to the
normal monitoring position, an alternative position shall be chosen, and a
correction to the measurements shall be made. For reference, a correction
of +2.5dB(A) and +3dB(A) shall be made to the free field measurements for road
traffic noise and construction noise respectively. 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 monitoring
and the impact monitoring shall be carried out at the same positions.
4.3
Monitoring Parameters of Construction Noise
4.3.1
The construction noise levels shall be measured for the time period
between 07:00 and 19:00 on normal weekdays using 30-minute A-weighted
equivalent continuous sound pressure level (Leq(30-min)) as the
monitoring parameter, other parameters including L10 and L90
should also be taken for reference. A sample data
record sheet for construction noise monitoring is shown in Appendix 4.1 for reference.
4.4
Monitoring Locations for Construction Noise
4.4.1
The proposed noise monitoring locations during the
construction phase are shown in Figure 4.1. Details of the
proposed noise monitoring locations are summarised in Table 4.1.

4.4.2
The status and location of NSRs may change after
issuing this manual. If such case exists, the ET Leader should propose
updated monitoring locations and seek approval from EPD and agreement from the
ER and the IEC before baseline monitoring commences.
4.4.3
When alternative monitoring locations are proposed, the
monitoring locations should be chosen based on the following criteria:
· Alternative
locations should be similarly exposed to potential noise impacts;
· It should be close
to the NSRs; and
· It should be
located where there would be minimal disturbance to the occupants.
4.5
Baseline Monitoring for Construction Noise
4.5.1
The ET shall carry out baseline noise monitoring prior to the
commencement of the construction activities. The baseline noise monitoring
shall be carried out daily at all of the identified monitoring stations for a
period of at least two weeks prior to the commencement of the construction
works. The ET shall develop a baseline monitoring schedule and submit it
to the IEC for approval prior to the commencement of the baseline
monitoring.
4.5.2
There shall not be any construction activities in the vicinity of the
monitoring stations during the baseline monitoring.
4.5.3
In exceptional cases, when insufficient baseline
monitoring data or questionable results are obtained, the ET Leader shall
liaise with EPD and in consultation with the IEC to agree on an appropriate set
of data to be used as a baseline reference.
4.6
Impact Monitoring for Construction Noise
4.6.1
Construction noise monitoring should be carried out at
the designated monitoring stations when there are Project-related construction
activities. An initial guide on the monitoring is to obtain one set of
30-minute measurement at each station between 07:00 and 19:00 hours on normal
weekdays at a frequency of once per week when construction activities are
underway.
4.6.2
If construction works are extended to include works
during the hours of 19:00 to 07:00, and/or percussive piling is being carried
out, applicable permits under NCO shall be obtained by the Contractor.
The monitoring requirements and conditions, if any, stipulated in the permits
have to be followed.
4.6.3
In case of non-compliance with the construction noise
criteria, more frequent monitoring, as specified in the EAP in Table
4.3 shall be carried out. This additional monitoring shall continue
until the recorded noise levels are rectified or proved to be irrelevant to the
construction activities.
4.7
Event and Action Plan for Construction Noise
4.7.1
The Action and Limit levels for construction noise are
defined in Table 4.2. Should
non-compliance with the criteria be identified, action in accordance with the
EAP in Table 4.3 shall be carried out.

4.8
Noise Parameters for Operation Road Traffic Noise
4.8.1
Notwithstanding the prediction that the NSRs will not be subject to
adverse noise impact during the operation phase of the Project with the
implementation of the proposed noise mitigation measures, noise monitoring
should be carried out during the first year after opening to ensure
accuracy of the traffic noise predictions.
4.8.2
The traffic noise levels should be measured twice at six-month intervals
within the first year upon completion of the Project. Measurements should
be made in terms of the A-weighted L10 over three half-hour periods
during the peak traffic hour, other parameters including Leq should
also be taken for reference.
4.8.3
Noise measurements shall not be made in fog, rain, wind
with a steady speed exceeding 5m/s or wind with gusts exceeding 10m/s.
The wind speed shall be checked with a portable wind speed meter capable of
measuring the wind speed in m/s.
4.9
Monitoring Locations for Road Traffic Noise
4.9.1
As shown in Table 4.4 and Figure 4.2, five designated monitoring locations are selected for the
operation phase noise monitoring.

4.9.2
The monitoring locations should be selected according
to the following criteria:
·
They should be at NSRs in the vicinity of recommended
direct technical remedies; preferably, there should be one representative
monitoring location near each type of noise screening element (i.e. LNRS,
vertical barrier, cantilever barrier and enclosure);
·
One high floor and one medium floor monitoring point
should be chosen at each location as far as practicable; and
·
Selected monitoring locations should allow monitoring
to be done twice within one year after the implementation of the mitigation
measures during the operation of the Project.
4.9.3
The status and locations of the NSRs may change after
this Manual is issued. If such cases exist, the ET Leader should propose
updated monitoring locations and seek approval from the ER and IEC and
agreement from EPD of the proposal.
4.9.4
When alternative monitoring locations are proposed, the
monitoring locations should be chosen based on the following criteria:
·
Alternative locations should be similarly exposed to
potential noise impacts;
·
It should be close to the NSRs; and
·
It should be located where there would be minimal
disturbance to the occupants.
4.10 Impact Monitoring for Operation Road Traffic Noise
4.10.1
The operation phase noise monitoring should be carried
out at a distance of 1m from the openable window and 1.2m above the floor level
of the noise sensitive receivers identified. The ET Leader should agree
with the IEC on any necessary corrections adopted.
4.10.2
Traffic noise monitoring
should be carried out at all the designated traffic noise monitoring
stations. The following is an initial guide on the traffic noise
monitoring requirements during the operation phase:
· One set of measurements at the morning traffic
peak hour on a normal weekday;
· One set of measurements at the evening traffic
peak hour on a normal weekday;
·
A concurrent census of traffic
flow and percentage of heavy vehicles shall be conducted for the Project roads
and the existing road network in the vicinity of each measuring point;
· Average vehicle speed estimated for Project road
and the existing road network in the vicinity of each measuring point; and
· The two sets of monitoring data should be
obtained within the first year of operation.
4.10.3 Measured
noise levels should be compared with the predicted noise levels by applying
appropriate conversion corrections to allow for the traffic conditions at the
time of measurement. A sample data record sheet for traffic noise
monitoring during the operation phase is shown in Appendix 4.2 for reference.
4.10.4
Each set of measurements shall include three
measurements of 30-minute. The parameters L10, Leq,
L90 and Lmax shall be recorded for data
auditing and reference.
4.10.5
The ET shall prepare a monitoring plan for the purpose of assessing the
accuracy of the traffic noise predictions by comparing the
noise impact predictions with the actual impacts. The monitoring plan shall be
submitted to EPD at least six months before the operation of the proposed roads
under the Project. The monitoring plan shall include monitoring locations,
monitoring schedules, methodology of noise monitoring such as noise measurement
procedures, traffic counts and speed checks, and methodology of comparison with
the predicted levels. The ET shall follow the monitoring plan unless with
prior justifications. Monitoring details and results including the comparison
between the measured noise levels and the predicted levels should be recorded
in a report to be deposited with EPD within one month of the completion of the
monitoring. The report should be certified by the ET Leader before
submitting it to EPD.
4.11
Event and Action Plan for Road Traffic Noise
4.11.1
The measured road traffic noise levels should be
compared with the predicted results and the predicted traffic flow conditions
(calculated noise levels based on concurrent traffic census obtained). In
case discrepancies are observed, explanations should be given to justify the
discrepancies.
Construction Phase
4.12.1
In order to reduce the noise impact of construction
site activities on nearby NSRs, the following mitigation measures have been
considered:
·
Use of Quality Power Mechanical Equipment (QPME);
·
Adoption of temporary movable noise barriers;
·
Use of acoustic enclosure;
·
Use of noise-insulating fabric;
·
Scheduling of PME/construction activities; and
·
Construction noise management plan.
Use of QPME
4.12.2
The use of QPME was considered to be a practicable
means to mitigate the construction noise impact. A quiet plant is defined
as a PME having an actual SWL lower than the value specified in the GW-TM.
Adoption of Temporary Movable Noise Barriers
4.12.3
The use of temporary movable noise barriers will be an
effective means to mitigate the noise impact arising from the construction
works, particularly for low-rise NSRs. For the low-rise nature of the
NSRs, movable noise barriers of 3m to 5m high (depending on the size of the
plant that requires to be screened) with skid footing should be used and
located within a few metres of stationary plants and mobile plants such that
the line of sight to the NSR is blocked by the barriers. The length of
the barriers should be at least five times greater than its height. These
movable noise barriers could produce at least 5dB(A) noise reduction for mobile
plants such as backhoes and rollers as well as large-scale plants such as
cranes.
Use of Acoustic Enclosure
4.12.4
Temporary acoustic enclosure is a common and effective
means to mitigate the noise impact arising from the operation of certain
small-size PMEs. A frame covered with noise insulation materials (sound
insulation materials with a superficial surface density of at least 14kg/m2
or sound absorbing materials of at least 50mm and average absorption
coefficient between 125Hz and 4000Hz of 0.4) could at least achieve 5dB(A)
to 10dB(A) reduction for plant items such as hand-held breaker and
circular wood saw. The locations of the temporary acoustic enclosure
should be adjusted wherever and whenever necessary to protect the noise
sensitive receivers, the enclosures should have no openings or gaps.
Use of Noise-Insulating Fabric
4.12.5 Noise insulation fabric would be installed for PMEs such as drill
rigs and piling, large diameter bored and reverse circulation drills.
These fabrics should be lapped such that there would be no openings or gaps in
the joints.
Scheduling of Construction Works
4.12.6
The Contractor shall liaise with the school
representative(s) to obtain the examination schedule so as to avoid noisy
construction activities during the school examination period. Scheduling
construction works outside the school examination period to less intrusive
periods or restricting critical works areas would reduce the overall
construction noise impacts at the NSRs and ensure compliance with the
construction noise criterion.
Construction Noise Management Plan
4.12.7 A construction noise management plan should be prepared during the
design/tendering and implementation stage of the construction works, to verify
the inventory of noise sources, update the construction noise impact assessment
if necessary, assess the effectiveness and practicality of all identified
measures and update the proposed noise mitigation measures as necessary.
4.12.8 The implementation schedule for the recommended mitigation measures
is presented in Appendix 1.2.
Operation Phase
Road Traffic Noise
4.12.9
Direct noise mitigation measures including low
noise road surfacing (LNRS), noise barriers and full enclosure have been
proposed to alleviate the traffic noise impact. Table 4.5
summarise the proposed noise mitigation measures.

4.12.10 After
implementing the proposed LNRS and noise barriers, the predicted overall noise
levels at all NSRs comply with the relevant noise criteria. Based on the
criteria as stated in Section 4.9.4 of the EIA Report, the eligibility test for
indirect noise mitigation measures is conducted. Details of the
eligibility test are given in Appendix 4.14 of the EIA Report.
As no representative existing NSRs would fall within all three testing
criteria, it is considered that no indirect mitigation measures would be
required.
4.12.11 The feasibility, practicability, programming and effectiveness of
the above mitigation measures have been reviewed and confirmed by the engineer.
Environmental reviews shall be conducted at a later design stage to
review and ascertain the proposed provisional noise mitigation measures taking
into account the latest design standard at that time for the suitability and
application of the LNRS materials.
4.12.12
The implementation schedule for the recommended
mitigation measures is presented in Appendix 1.2.
4.13.1 Regular environmental site inspections and audits during the
construction phase of the Project should be conducted at least once per week to
ensure proper implementation of mitigation measures and good site practices as
listed in Appendix
1.2 and the noise
control requirements stated in EPD’s Recommended Pollution Control Clauses
for Construction Contracts to further minimise the potential noise nuisance
during the construction phase.
5
WATER QUALITY
5.1.1
Potential water pollution sources from the construction
and operation of the Project have been identified including construction site
runoff, wastewater from general construction activities, diversion /
modification of box culvert, accidental spillage and sewage effluent from the
construction workforce. With the implementation of the recommended
mitigation measures, no unacceptable water quality impacts would be expected.
No water quality monitoring is therefore considered necessary. Regular
site inspections and audits are recommended during the construction phase to
ensure the recommended mitigation measures are properly implemented.
5.2.1
Mitigation measures for water quality control during
the construction phase have been recommended in the EIA Report. The
Contractor should be responsible for the design and implementation of these
measures. Recommended mitigation measures to minimise the adverse impacts
on water quality during the construction activities are listed in the
implementation schedule given in Appendix 1.2.
5.3
Construction Site Audits
5.3.1
Regular site inspections and audits should be conducted
to ensure that the recommended mitigation measures are properly implemented
during the construction phase of the Project. It can also provide
effective control of any malpractices and therefore achieve continual
improvement of environmental performance on site.
Site Inspections
5.3.2
Regular site inspections shall be carried out by the ET
at least once per week and shall be based on the mitigation measures for water
pollution control recommended in Appendix 1.2. If the recommended mitigation measures are not fully or
properly implemented, the deficiency shall be recorded and reported to the site
management. Suitable actions are to be carried out to:
(i)
Investigate the problems and the
causes;
(ii)
Issue action notes to the Contractor
who is responsible for the works;
(iii) Implement remedial and corrective actions
immediately;
(iv) Re-inspect the site conditions upon completion
of the remedial and corrective actions; and
(v)
Record the event and discuss it
with the Contractor for preventive actions.
Compliance Audits
5.3.3
Monitoring of the treated effluent quality from the
Works Areas is required during the construction phase of the Project. The
monitoring shall be carried out at the pre-determined discharge point.
Compliance audits are to be undertaken to ensure that a valid discharge licence
has been issued by EPD prior to the discharge of effluent from the Project
site. The monitoring frequency and parameters specified in the discharge
licence shall be followed during the monitoring. All monitoring
requirements shall be approved by EPD. The audit results reflect whether
the effluent quality complies with the discharge licence requirements. In
case of non-compliance, suitable actions shall be undertaken to:
(i)
Notify the site management about
the non-compliance;
(ii)
Identify the sources of pollution;
(iii) Check the implementation status of the
recommended mitigation measures;
(iv) Investigate the operating conditions of the
on-site treatment systems;
(v)
Implement corrective and remedial
actions to improve the effluent quality;
(vi) Increase monitoring frequency until the effluent
quality complies with the discharge licence requirements; and
(vii)
Record the non-compliance and
propose preventive measures.
6
WASTE MANAGEMENT
6.1.1
Construction and Demolition (C&D) materials, chemical
waste and general refuse from the workforce would be generated during the
construction phase. This section sets out the handling, recycling,
storage, transportation and disposal measures for these wastes which are
recommended to avoid and minimise potential adverse impacts associated with
waste arising from the construction of the Project.
6.1.2
It is expected that no waste will be generated as a
result of the operation of the Project, and thus there would be no adverse
environmental impacts related to waste management during the operation phase of
the Project. Monitoring and audit programme for the operation phase of
the Project would not be required.
6.2
Waste Management Approach
Management of Waste
Disposal
6.2.1
In accordance with the Waste Disposal (Charges
for Disposal of Construction Waste) Regulation, the Contractor should open
a billing account with the EPD. Every construction waste or public
fill load to be transferred to the Government waste disposal facilities, namely
public fill reception facilities, construction waste sorting facilities, and
landfills will require a valid “chit” which contains information of the account
holder (the Contractor) to facilitate waste transaction recording and billing
to the waste producer.
6.2.2
Inert C&D materials generated from the Project will
be transferred to Tuen Mun Area 38 Fill Bank (TMFB), or other
public fill reception facilities, managed by Civil Engineering and Development
Department (CEDD), while the non-inert C&D materials, after segregation,
will be sent to North East New Territories Landfill (NENT) or North East New
Territories Landfill Extension (NENTX), or other waste disposal facilities,
managed by the EPD.
6.2.3
A trip-ticket system will also be established in
accordance with DevB TC(W) No.6/2010 to monitor the disposal of
construction waste at the landfill and to control fly-tipping. In
addition, all dump trucks should be equipped with GPS or equivalent systems for
monitoring their transportation routes and parking locations to prohibit
illegal dumping and landfilling of C&D materials. The Contractor
should maintain a recording system to record the amount of C&D materials
generated, recycled and disposed of at the disposal sites as well as the
transportation routing and parking locations of the dump trucks. The
trip-ticket system and the abovementioned recording system will be included as
part of the contractual requirements and implemented by the Contractor(s).
6.2.4
As per recommendation under ETWB TC(W) No. 19/2005,
a WMP, with details of the amount of waste generated, recycled and disposed of
(including the disposal sites), will be established and implemented during the
construction phase as part of the EMP. The Contractor will be required to
prepare the EMP and submit it to the ER under the Contract for approval prior
to implementation.
Approach
to Reduce Waste Generation
Construction and Demolition (C&D) Materials
6.2.5
C&D materials generated from the construction works
of the Project comprise both inert C&D materials (i.e. excavated soil,
rock, broken concrete) and non-inert C&D materials (i.e. vegetation, wood,
plastics, packaging materials, etc.). The inert C&D materials will
be segregated from other non-inert C&D materials and be sent to TMFB, or
other public fill reception facilities. The non-inert C&D materials
will be further segregated into recyclable materials, such as cardboard, carton
box, waste paper and scrap metal for collection by recyclers, and
non-recyclable materials, such as waste timber and packaging materials, which
will be disposed of at NENT/NENTX, or other waste disposal facilities.
General Refuse
6.2.6
General refuse will be generated from daily site office
operations and workforce. Recycling bins should be provided at
strategic locations, such as the entrance of the site office to facilitate the
recovery of aluminium cans and waste paper generated from the
Site. Materials collected in the recycling bins should be collected
by or sold to local recyclers.
Management of Chemical Waste
6.2.7
Chemical wastes likely to be generated from the
construction of the Project may include residual paints and solvents and used
lubricant oil from maintenance of the construction plant. It is
anticipated that the quantity of chemical waste to be generated will be small
and in the order of a few hundred litres per month during the construction
phase. These chemical wastes will be stored and disposed of in an
appropriate manner, as outlined in the Waste Disposal (Chemical Waste)
(General) Regulation and the Code of Practice on the
Packaging, Labelling and Storage of Chemical Wastes.
6.2.8
The Contractor should register as a chemical waste
producer with the EPD, and handle the chemical waste in accordance with
the Code of Practice on the Package, Labelling and Storage of Chemical
Wastes. A brief summary of the site arrangement should be as
follows:
Storage Containers
· Be suitable for the substance they are holding, resistant to
corrosion, maintained in good condition, and securely closed;
· Have a capacity of less than 450L unless specifications have been
approved by the EPD; and
· Display a label in English and Chinese in accordance with
instructions prescribed in Schedule 2 of the Regulations.
Storage Area
· Be clearly labelled and used solely for the storage of chemical
waste;
· Be enclosed on at least three sides;
· Have an impermeable floor and bunding, of a capacity to accommodate 110% of the volume of the largest
container or 20% by volume of the chemical waste stored in that area, whichever
is the greatest;
· Have adequate ventilation;
· Be covered to prevent rainfall entering (with water collected
within the bund be disposed of as chemical waste when necessary); and
· Be arranged so that incompatible materials are appropriately
separated.
Disposal
· Be collected by a licensed chemical waste collector; and
· Be disposed/transferred to a facility licensed to receive chemical
waste, such as Chemical Waste Treatment Facility (CWTF) at Tsing Yi or other
chemical waste recyclers.
6.3.1
At the commencement of the construction works, training
should be provided to workers on the concepts of site cleanliness and
appropriate waste management procedures, including waste reduction, reuse and
recycling.
6.4.1
In order to review the good site practices of waste
management, regular environmental site inspections and audits should be carried
out by the ET at least once per week to check whether the Contractor has
implemented the recommended good site practices and other mitigation
measures. The inspection 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. Designated staff of the Contractor responsible for
resource allocation, staff training and controlling the relevant documents will
also be interviewed to review the effectiveness of site management.
Good Site Practice
6.5.1
Under the condition of good site practices are strictly
followed, it is anticipated that no adverse waste management-related impacts
would arise. Recommendations for good site practices during the
construction activities include:
· Nomination of approved personnel, such as a site manager, to be
responsible for the implementation of good site practices, arrangements for
collection and effective disposal to an appropriate facility, of all wastes
generated at the site;
· Training of site personnel in site cleanliness, appropriate waste
management procedures, including chemical waste handling procedures, and
concepts of waste reduction, reuse and recycling;
· Provision of sufficient waste disposal points and regular
collection for disposal;
· Appropriate measures to minimise windblown litter and dust during
the transportation of waste by either covering trucks or by transporting wastes
in enclosed containers;
· Separation of chemical wastes for special handling and appropriate
treatment at the CWTF;
· Regular cleaning and maintenance programme for drainage systems,
sumps and oil interceptors;
· Implementation with a recording system for the amount of wastes
generated, recycled and disposed (including the disposal sites; should be
proposed; and
· A waste management plan (WMP) should be prepared in accordance
with ETWB TC No.19/2005 and submitted to the ER for approval.
Waste Reduction Measures
6.5.2
Good management and control can prevent the generation
of a significant amount of waste. Waste reduction is best achieved
at the planning and design stage, as well as by ensuring the implementation of
good site practices. Recommendations to achieve waste reduction
include:
· Segregation and storage of different types of waste in different
containers, skips or stockpiles to enhance the reuse or recycling of material
and their proper disposal;
· Encourage collection of aluminium cans and waste paper by
individual collectors during construction with separate labelled bins being
provided to allow the segregation of these wastes from other general refuse
generated by the workforce;
· Any unused chemicals and those with remaining functional capacity
be recycled as far as possible;
· Use of reusable non-timber formwork to reduce the amount of
C&D materials;
· Before disposal of construction waste, wood, steel and other metals
should be separated, to the extent practical for re-use and/or recycling to
reduce the quantity of waste to be disposed to the landfills;
· Proper storage and site practices to reduce the potential for
damage or contamination of construction materials; and
· Plan and stock construction materials carefully to reduce the
amount of waste generated and avoid unnecessary generation of waste.
6.5.3
The waste management approach recommended in the EIA
Study is outlined in Appendix 1.2.
6.5.4
In the event of complaints, or non-compliance/area of
improvement is observed, the ET and the Contractor should be responsible for
reviewing the effectiveness of these mitigation measures and for proposing to
ER for approval, designing and implementing alternative or additional
mitigation measures as appropriate.
7
LAND CONTAMINATIOn
7.1.1
The land contamination assessment has examined the
potential contaminating land uses within the Project area and investigated any
potential land contamination impacts arising from the Project.
7.1.2
Based on the site appraisal, no adverse land contamination
impact arising from Project is anticipated. No EM&A programme is
therefore required.
8
ECOLOGY
8.1.1
Potential ecological impacts arising from the
construction and operation phases of the Project were assessed in the EIA
Report. There would be no direct impact on important ecological resources
anticipated. Mitigation measures have been recommended to minimize the
potential indirect impacts on the nearby sensitive ecological resources (e.g.
North District Park Egretry and Day Roost (NDPEDR)). With the
implementation of appropriate mitigation measures, no unacceptable adverse
residual impacts would be anticipated. Nonetheless, EM&A is
considered necessary during both the construction and operation phases of the
Project and the requirements are described below.
8.2.1
The mitigation measures recommended in the EIA Report
to avoid / minimize / compensate potential ecological impacts are provided in Appendix 1.2. All the proposed mitigation measures are considered feasible
and effective to mitigate the potential impacts.
8.3
Monitoring Requirements
Pre-Construction Ecological Survey
8.3.1
A pre-construction ecological survey that
covering the whole breeding season (March to August) will be conducted at the
NDPEDR to find out the peak month(s) of the breeding season. The
pre-construction ecological survey shall also verify the status and updated
location of the NDPEDR for determining the 100m area around the NDPEDR for
concerned mitigation measures and form a baseline information for the
monitoring during construction and operation phase, which will be discussed in
the below section. The findings of the pre-construction ecological survey
should be submitted to relevant Government departments no later than one month
before the commencement of construction of the project. Subject to the findings
of the survey, the Pre-Construction Survey Report should list out details of
all measures to minimize the potential impacts on the North District Park Egretry during the construction of the Project.
Ecological Survey during the
Construction Phase and Operation Phase
8.3.2
Regular monitoring will be conducted
within 100m of the NDPEDR at a frequency of at least monthly or more frequent
during construction phase and the first breeding season (March to August) after
operation. If the commencement of operation is in the middle of a breeding
season, the operation phase monitoring will cover that breeding season and the
next breeding season, criteria to be monitored include the status, location and
extent of NDPEDR, the condition of trees used as breeding and roosting
activities, the species, abundance and the returning time of the breeding and
roosting ardeids, as well as their flight height and flight line. The usage of the ardeid night roost should
be reviewed and analysed. If any
significant decline of the usage of the NDPEDR by ardeids is identified, the
cause of the decline, with reference to any changes in site condition or
disturbances detected, should be reviewed to identify any unpredicted indirect
ecological impacts arising from the proposed Project. Remedial measures should
be developed and implemented by the Contractor as necessary. The monitoring results and evaluation of
the usage of the NDPEDR should be reported in the monthly EM&A
Reports.
Methodology of the Surveys
8.3.3 The pre-construction verification survey
and the regular monitoring survey should be conducted to cover the peak period
of ardeid activities, starting from approximately an hour before sunset and
last until nightfall when observation of ardeid is no longer possible.
The exact time of sunset on the date of the survey should make reference
on the website of Hong Kong Observatory. Direct observation should be made from
an appropriate vantage point which enables the view of the night roost.
8.3.4 Any changes in site condition or
disturbances detected or observed at the monitoring locations, including both
construction and non-construction related activities, during the regular
monitoring survey should also be recorded.
8.3.5 Both the pre-construction verification
survey and the regular monitoring survey should also be conducted by
experienced ecologist(s) with at least 7 years of relevant working experience.
8.4.1
Site audits should be undertaken on a weekly basis to
check the proper implementation and maintenance of recommended mitigation
measures during the construction phase of the Project.
9
LANDSCAPE AND VISUAL
9.1.1
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 to confirm the recommended
landscape and visual impact mitigation measures are effectively implemented.
9.2.1
The landscape and visual mitigation measures should be
incorporated into the detailed design. The mitigation measures during the
construction and operation phases as recommended in the EIA Report are
presented in Appendix
1.2. Where feasible, the construction phase
mitigation measures should be implemented as early as possible in order to
minimize the landscape impacts in the construction phase 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 before
commissioning of the Project.
9.2.2
Any potential conflicts among the proposed mitigation
measures, the Project works, and operation requirements should also be
identified and resolved at an early stage. Any changes to the mitigation
measures should be incorporated into the detailed design.
9.3.1
Site audits should be undertaken during the
construction phase and the 12-month establishment period (operation phase) to
check that the proposed landscape and visual mitigation measures are properly
implemented and maintained as per their intended objectives. Site audit for the
off-site woodland compensation should be carried out throughout the agreed
establishment period with LCSD and CEDD.
9.3.2
The ET shall audit the implementation of landscape
construction works particularly during site clearance operations when the proposed
tree felling and transplanting will take place and subsequent tree maintenance
operations and planting works.
9.3.3
Site inspections should be undertaken by the ET at
least once every month during the construction period, and once every two months
for the 12-month establishment period during the operation phase.
10 CULTURAL HERITAGE
10.1.1
Potential cultural heritage impacts arising from the
construction phase of the Project were identified and assessed in the EIA
Report. With the implementation of the recommended mitigation measures,
no unacceptable cultural heritage impacts would be expected.
10.1.2
Potential cultural heritage impact arising from the
operation phase of the Project is not anticipated. No mitigation
measures, monitoring and audit are considered necessary during the operation
phase of the Project.
Archaeology
Construction
Phase
10.2.1
As a precautionary measure, the project proponent and
his/her contractor are required to inform AMO immediately when any antiquities
or supposed antiquities under the Antiquities and Monuments Ordinance (CAP.53)
are discovered during the course of works.
Operation Phase
10.2.2 No excavation works of the Project will be involved during the
operation phase, so no adverse archaeological impact is anticipated. Thus, no
mitigation measure or EM&A is required.
Built Heritage
Construction Phase
10.2.3 No impact to all identified graded historic buildings, and no
grading built heritage items except Shrine, So Kwun Po Tsuen (BH-01()) is anticipated due to considerable separation distance from the
boundary of the Works Area. However, it is
recommended to monitor any vibration and building movement induced by the
proposed works on the graded historic buildings, i.e. No.5 Ng Uk Tsuen (GB-03()), which is closest to the boundary of the Works Area, as well as on
the Grade 1 historic building, i.e. Pang Ancestral Hall (GB-01(2)).
This will ensure that there are no negative impacts from vibration on the
graded historic buildings and will also provide relevant reference data for
impact assessment.
10.2.4 Although Shrine, So Kwun Po Tsuen (BH-01()) is located relatively closer (about
20m) to the boundary of the Works Area, potential direct and vibration impacts
are not anticipated as the closest major underground construction works like
piling and piling cap construction are located around 300m away. No
mitigation measure or EM&A is required.
Operation Phase
10.2.5 No direct and/or indirect impacts are anticipated from the proposed
new roads during the operation phase. No mitigation measure or EM&A is
required.
11 Environmental AUDIT
11.1.1
Site inspections provide a direct means to assess and
confirm that the Contractor’s environmental protection and pollution control
measures are in compliance with the contract specifications. The site
inspection will be undertaken routinely by the ET to verify that appropriate
environmental protection and pollution control mitigation measures are properly
implemented in accordance with the EIA recommendations. In addition, the
ET will be responsible for defining the scope of the inspections, detailing any
deficiencies that are identified and reporting any necessary action and/or
additional mitigation measures that were implemented as a result of the
inspection.
11.1.2
Site inspections should be carried out at least once
per week. The areas of inspection should not be limited to the general
environmental conditions in the vicinity of the site and the pollution control
and mitigation measures within the site; the environmental conditions outside
the site area which are likely to be affected, directly or indirectly, by site
activities. The ET Leader should make reference to the following
information in conducting the inspections:
· The EIA Study and EM&A recommendations on environmental
protection and pollution control mitigation measures;
· Ongoing results of the EM&A programme;
· Works progress and programme;
· Individual works method statements which should include proposals
on associated pollution control measures;
· Contract specifications on environmental protection;
· Relevant environmental legislation and guidelines; and
· Previous site inspection results undertaken.
11.1.3
The Contractor will update the ET with relevant
information on the construction works prior to carrying out the site inspections.
The site inspection results and their associated recommendations on
improvements to the environmental protection and pollution control works should
be submitted to the IEC and the Contractor in two working days, for reference
and for taking immediate action. Should actions be necessary, the ET will
follow up with recommendations on improvements to the environmental protection
and pollution control works and will submit these recommendations in a timely
manner to the IEC and the Contractor. They will also be presented, along
with the remedial actions taken, in the monthly EM&A report. The
Contractor should follow the procedures and time frames stipulated in the
environmental site inspection for the implementation of the mitigation proposal.
An action reporting system will be formulated and implemented to report on any
remedial measures implemented subsequent to the site inspections.
11.1.4
Ad hoc site inspections will also be carried out by the
ET and site audits by the IEC if significant environmental issues are
identified. Inspections may also be required subsequent to receipt of an
environmental complaint, or as part of the associated investigation work, as
specified in the Action Plan for environmental monitoring and audit.
11.2
Compliance with Legal and Contractual Requirements
11.2.1
The Contractor should comply with contractual
environmental protection and pollution control requirements, Hong Kong’s
environmental protection and pollution control laws.
11.2.2
In order that the works are in compliance with the
contractual requirements, all works method statements (where relevant to
environmental measures) submitted by the Contractor to the ER for approval
should also be sent to the ET Leader for vetting to see whether sufficient environmental
protection and pollution control measures have been included.
11.2.3
The ET shall review all the progress and programme of
the works to check that relevant environmental laws have not been violated, and
that any foreseeable potential for violating the laws can be prevented.
11.2.4
The Contractor shall regularly copy inspection relevant
documents to the ET Leader so that the works checking and auditing process
could be carried out effectively. The relevant documents are expected to
include the updated work progress reports, the updated works programme, the
application letters for different licences/permits under the environmental
protection laws, all valid licences/permits and environmental related
records. The site diary should also be available for the ET Leader’s
inspection upon his request.
11.2.5
After reviewing the documentation, the ET Leader shall
advise the IEC and the Contractor of any non-compliance with the 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 of the licence/permit application and any
environmental protection and pollution control preparation works is incompatible
with the works programme or may result in a potential violation of
environmental protection and pollution control requirements, he should also
advise the Contractor and the ER in due course.
11.2.6
Upon receipt of the advice, the Contractor should
undertake immediate action to remedy the situation. The ER should
follow up to ensure that appropriate action has been taken by the Contractor in
order to satisfy contractual and legal requirements.
11.3
Environmental Complaints
11.3.1 Complaints
shall be referred to the ET Leader for action. The ET Leader shall
undertake the following procedures upon receipt of any environmental complaint:
(i)
Log the 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 Environmental
Protection Department (EPD), submit an interim report to the EPD on the status
of the complaint investigation and follow-up action within the time frame
assigned by the EPD;
(vii)

the complainant (if the source of complaint is identified through EPD, the
results should be reported within the timeframe assigned by EPD); and
(ix)
Record the complaint, investigation, subsequent actions
and the results in the monthly EM&A reports.
11.3.2 A
flow chart of the complaint response procedure is shown in Appendix 11.1.
11.3.3 During
the complaint investigation work, the Contractor and ER shall work with the ET
in providing all necessary information and assistance for the completion of the
investigation. If mitigation measures are identified as required during
the investigation by the ET, the Contractor should promptly carry out the
mitigation works. The ER shall ensure that the measures have been carried
out by the Contractor.
11.4.1 The ET Leader will keep a contemporaneous logbook of each and every
instance or circumstance or change of circumstances which may affect the EIA
and every non-compliance from the recommendations of the EIA Report or the EP.
The ET Leader will notify the IEC within one working day of the occurrence of
any such instance or circumstance or change of circumstance. The ET
Leader’s logbook will be kept readily available for inspection by persons
assisting in the supervision of the implementation of the EIA Report
recommendations (such as IEC and Contractor) or by EPD or his authorised
officers.
12 REPORTING
12.1.1 Upon
agreement with the ER and EPD, reports can be provided in electronic format.
This would enable a transition from a paper/ historic and reactive
approach to an electronic/real-time proactive approach. All monitoring
data, including baseline and impact monitoring, shall also be submitted in
electronic format.
12.1.2
The ET Leader shall submit baseline monitoring reports, monthly EM&A

the major activities being carried out on-site during
the period;
·
weather conditions during the period; and
·
any other factors which might affect the monitoring
results.
(vii)
Compare and contrast the EM&A
data with the EIA predictions and annotate with an explanation for any
discrepancies;
(viii) Provide clear-cut decisions on the environmental
acceptability of the project with reference to the specific impact hypothesis;
(ix)
Advice on the solid and liquid
waste management status;
(x)
A summary of non-compliance
(exceedances) of the environmental quality performance limits (Action and Limit
levels);
(xi)
A brief review of the reasons for
and the implications of non-compliance including a review of pollution sources
and working procedures;
(xii)
A summary description of the
actions taken in the event of non-compliance and any follow-up procedures
related to earlier non-compliance;

of the summons and successful prosecutions for breaches of the current
environmental protection/pollution control legislations, locations and nature
of breaches, investigation, follow-up actions taken and results;
(xvi) Review the practicality and effectiveness of the
EIA process and EM&A programme (for example, a review of the effectiveness
and efficiency of the mitigation measures and the performance of the
environmental management system, that is, of the overall EM&A programme),
recommendations (for example, any improvement in the EM&A programme); and
(xvii)
A conclusion to state the return to
ambient and/or the predicted scenario as the EIA findings.
12.5.1
The site documents (such as monitoring field records,
laboratory analysis records, site inspection forms etc.) are not required to be
included in the EM&A Reports for submission. However, the documents
will be kept by the ET Leader and be ready for inspection upon request.
Relevant information will be clearly and systematically recorded in the
documents. The documents and data (e.g. waste data) will be kept for at
least one year after the completion of the construction contract.
