THE PLANNED KTD
3.1
Introduction
3.2
Air Quality Impact
3.2.1
The findings of the EIA indicated that with the
implementation of dust suppression measures stipulated in the Air Pollution
Control (Construction Dust) Regulation during construction, no adverse
residual air quality impact would be expected. Air quality monitoring is
not required. However, regular site audit during construction
phase (see Section 14 of this Manual) is required to ensure compliance of the Air Pollution
Control (Construction Dust) Regulation.
3.2.2
As described in the EIA
Report, no adverse air quality impacts at the ASRs are expected during the
construction phase of this DP.
3.2.3
Mitigation measures for
dust are recommended in the EIA Report. The Contractor shall be
responsible for the design and implementation of these measures.
3.2.4
In order to ensure
compliance with the acceptable criteria at the ASRs at all time, requirements
of the Air Pollution Control (Construction Dust) Regulation shall be
adhered to during the construction period. Misting for any stockpile of
materials and provision of windbreaks on three sides are proposed to prevent
wind erosion. In addition, the following good site practices are
recommended to minimise dust and other air pollutants impacts during excavation,
transportation, and loading and unloading of dusty material:
l Stockpiling site(s) should be lined
with impermeable sheeting and bunded. Stockpiles should be fully covered
by impermeable sheeting to reduce dust emission.
l Misting for the dusty material
should be carried out before being loaded into the vehicle.
l Any vehicle with an open load
carrying area should have properly fitted side and tail boards.
l Material having the potential to
create dust should not be loaded from a level higher than the side and tail
boards and should be dampened and covered by a clean tarpaulin.
l The tarpaulin should be properly
secured and should extent at least 300 mm over the edges of the sides and
tailboards. The material should also be dampened if necessary before
transportation.
l The vehicles should be restricted to
maximum speed of 10 km per hour and confined haulage and delivery vehicle to
designated roadways insider the site. On-site unpaved roads should be
compacted and kept free of lose materials.
l Vehicle washing facilities should be
provided at every vehicle exit point.
l The area where vehicle washing takes
place and the section of the road between the washing facilities and the exit
point should be paved with concrete, bituminous materials or hardcores.
l Every main haul road should be
scaled with concrete and kept clear of dusty materials or sprayed with water so
as to maintain the entire road surface wet.
l Every stock of more than 20 bags of
cement should be covered entirely by impervious sheeting placed in an area
sheltered on the top and the three sides.
l Every vehicle should be washed to
remove any dusty materials from its body and wheels before leaving the
construction sites.
3.2.5
The implementation
schedule for the recommended air quality impact mitigation measures is
presented in Appendix
A2.
3.3
Noise Impact
Noise Parameters
3.3.1
The construction noise
level shall be measured in terms of the A-weighted equivalent continuous sound
pressure level (Leq). Leq (30 minutes) shall be
used as the monitoring parameter for the time period between 0700 and 1900
hours on normal weekdays. For all other time periods, Leq (5 minutes)
shall be employed for comparison with the Noise Control Ordinance (NCO)
criteria.
3.3.2
Supplementary information
for data auditing, statistical results such as L10 and L90
shall also be obtained for reference. A sample data record sheet based on
the one presented in the EM&A Guidelines for Development Projects in Hong Kong is shown in Appendix B.
The ET Leader may modify the data record sheet for this EM&A programme, of
which the format should be agreed by the ER and the IEC.
Monitoring Equipment
3.3.3
As referred to in 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 shall be used for carrying
out the noise monitoring. Immediately prior to and following each noise
measurement the accuracy of the sound level meter shall 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 calibration
level from before and after the noise measurement agree to within 1.0 dB.
3.3.4
Noise measurements
shall not be made in fog, rain, wind with a steady speed exceeding 5 m/s or
wind with gusts exceeding 10 m/s. The wind speed shall be checked with a
portable wind speed meter capable of measuring the wind speed in m/s.
3.3.5
The ET is responsible
for the provision of the monitoring equipment. He 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.
Monitoring Locations
3.3.6
The locations of
construction noise monitoring stations are summarized in Table 3.1 and
shown in Figure 2.2.
These locations represent the worst affected sensitive receivers during
construction.

3.3.7
The status and
locations of noise sensitive receivers may change after issuing this
Manual. If such case exists, the ET Leader shall propose updated
monitoring locations and seek approval from EPD and agreement from the ER and
the IEC before baseline monitoring commences.
3.3.8
When alternative
monitoring locations are proposed, the monitoring locations shall be chosen
based on the following criteria:
(i)
Monitoring at sensitive receivers close to the major site activities which are
likely to have noise impacts;
(ii) Monitoring
at the noise sensitive receivers as defined in the Technical Memorandum; and
(iii)
Assurance of minimal
disturbance to the occupants during monitoring.
3.3.9
The monitoring station
shall normally be at a point 1 m from the exterior of the sensitive receiver
building facade and be at a position 1.2 m above the ground. 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. For
reference, a correction of +3 dB(A) shall be made to the free field
measurements. 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.
Baseline Monitoring
3.3.10 The ET shall carry out baseline
noise monitoring prior to the commencement of the construction works. The
baseline monitoring shall be carried out daily for a period of at least two
weeks. Before commencing the baseline monitoring, the ET shall develop
and submit to the IEC the baseline monitoring programme such that the IEC can
conduct on-site audit to ensure accuracy of the baseline monitoring results.
3.3.11 There shall not be any construction
activities in the vicinity of the stations during the baseline monitoring.
3.3.12 In exceptional cases, when
insufficient baseline monitoring data or questionable results are obtained, the
ET Leader shall liaise with the ER, EPD and IEC to agree on an appropriate set
of data to be used as a baseline reference and submit to the ER and IEC for
agreement and EPD for approval.
Impact Monitoring
3.3.13 Noise monitoring shall be carried
out at all the designated monitoring stations during the construction phase of
the DP. The monitoring frequency shall depend on the scale of the
construction activities. The following is an initial guide on the regular
monitoring frequency for each station on a weekly basis when noise generating
activities are underway:
·
one set of measurements
between 0700 and 1900 hours on normal weekdays.
3.3.14 If construction works are extended
to include works during the hours of 1900 – 0700 as well as public holidays and
Sundays, additional weekly impact monitoring shall be carried out during
respective restricted hours periods. Applicable permits under NCO shall
be obtained by the Contractor.
3.3.15 If a school exists near the
construction activity, noise monitoring shall be carried out at the monitoring
stations for the schools during the school examination periods. The ET
Leader shall liaise with the school’s personnel and the Examination Authority
to ascertain the exact dates and times of all examination periods during the
course of the contract.
3.3.16 In case of non-compliance with the
construction noise criteria, more frequent monitoring, as specified in the
Event and Action Plan in Table 3.3, shall be carried out. This
additional monitoring shall be continued until the recorded noise levels are
rectified or demonstrated to be unrelated to the construction activities.
Event and Action Plan
3.3.17 The Action and Limit levels for
construction noise are defined in Table 3.2. Should non-compliance
of the criteria occur, action in accordance with the Event and Action Plan in Table
3.3 shall be implemented.

* 70 dB(A) and 65 dB(A) for
schools during normal teaching periods and school examination periods,
respectively.
Mitigation Measures
Construction Phase
3.3.18 To alleviate the construction noise
impact on the affected NSRs, movable noise barriers and acoustic mats are
proposed to be provided for particular items of plant and construction works.
It is anticipated that a movable noise barrier with a cantilevered upper
portion located within 5m from any static or mobile plant can provide 5 dB(A)
noise reduction for mobile plant and 10 dB(A) noise reduction for static plant.
The barrier material shall have a surface mass of not less than 14 kg/m2
on skid footing with 25mm thick internal sound absorptive lining to achieve the
maximum screening effect.
3.3.19 In addition, the good site practices
listed below should be adopted by all the Contractors to further ameliorate the
noise impacts.
·
Only well-maintained
plant should be operated on-site and plant should be serviced regularly during
the construction program.
·
Silencers or mufflers
on construction equipment should be utilised and should be properly maintained
during the construction program.
·
Mobile plant, if any, should be sited as
far away from NSRs as possible.
·
Machines and plant
(such as trucks) that may be in intermittent use should be shut down between
works periods or should be throttled down to a minimum.
·
Plant known to emit
noise strongly in one direction should, wherever possible, be orientated so
that the noise is directed away from the nearby NSRs.
·
Material stockpiles and
other structures should be effectively utilised, wherever practicable, in
screening noise from on-site construction activities.
3.3.20 If the above measures are not
sufficient to restore the construction noise quality to acceptable levels upon
the advice of ET Leader, the contractor shall liaise with the ET Leader to
identify further mitigation measures. They shall be proposed to ER for
approval, and the contractor shall then implement these additional mitigation
measures.
Operation Phase
3.3.21 The EIA report has provided the
maximum allowable sound power levels for fixed noise sources from ventilation
fans. The SWL criteria shall be implemented and refined by the
Contractor. The Contractor should also carry out a noise commissioning
test for all fixed noise sources before operation of the Project, in order to
ensure compliance of the operational noise levels with the TM’s stipulated
noise standard.
3.3.22 The implementation schedule for the
recommended mitigation measures is presented in Appendix A2.

3.4
Water Quality Impact
Introduction
3.4.1
No operational phase
marine water quality impact would be expected from the Project, water quality
monitoring is not considered necessary. However, it is recommended that
regular site audits (at least once per week) be undertaken to inspect the
construction activities and works areas in order to ensure the recommended
mitigation measures are properly implemented. Proposed mitigation measures
for containing and minimizing water quality impacts are listed in the
implementation schedule given in Appendix A2.
3.4.2
Implementation of
regular site audits (at least once per week) during the construction phase is
to ensure that the recommended mitigation measures are to be properly
undertaken. It can also provide an effective control of any malpractices
and therefore achieve continual improvement of environmental performance on
site.
3.4.3
Site audits shall
include site inspections and monitoring audits.
Site Inspections
3.4.4
Site inspections shall
be carried out by the ET and shall be based on the mitigation measures for water
pollution control recommended in the implementation schedule as attached in Appendix A2.
In the event that the recommended mitigation measures are not fully or
properly implemented, deficiency shall be recorded and reported to the site
management. Suitable actions are to be carried out to:
·
Investigate the problems and the causes;
·
Issue action notes to the Contractor which is
responsible for the works;
·
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 Contractor for
preventive actions.
Monitoring Audits
3.4.5
Monitoring audits are
to be undertaken to ensure that a valid discharge license has been issued by
EPD prior to the discharge of effluent from the construction site.
Parameters included in the WPCO licence, will also be included in the
monitoring programme. The chemical testing of water samples collected in
the monitoring programme should be undertaken by a Hong Kong Laboratory
Accreditation Scheme (HOKLAS) accredited laboratory. The audit results
reflect whether the effluent quality is in compliance with the discharge
license requirements and that the recommended water quality mitigation measures
are properly implemented. In case of non-compliance, suitable actions
should be undertaken to:
·
Notify the site management for the non-compliance;
·
Identify the sources of pollution;
·
Check the implementation status of the recommended
mitigation measures;
·
Investigate the operating conditions of the on-site
treatment systems;
·
Implement corrective and remedial actions to improve
the effluent quality;
·
Increase monitoring frequency until the effluent
quality is in compliance with the discharge licence requirements; and
·
Record the non-compliance and propose preventive
measures.
3.5
Waste Management Implications
3.5.1
Waste management will
be the Contractor’s responsibility to ensure that all wastes produced during the
construction works of the Project are handled, stored and disposed of in
accordance with good waste management practices and EPD’s regulations and
requirements.
3.5.2
Waste materials
generated during the construction works, such as construction and demolition
(C&D) material, general refuse and chemical wastes, are recommended to be
audited at regular intervals (at least once per week) to ensure that proper
storage, transportation and disposal practices are being implemented. This
monitoring of waste management practices will ensure that these solid and
liquid wastes are not disposed into the nearby harbour waters. The
Contractor will be responsible for the implementation of any mitigation
measures to minimise waste or redress problems arising from the waste
materials.
Waste
Control and Mitigation Measures
3.5.3
Mitigation measures for
waste management are summarised below. With the appropriate handling,
storage and removal of waste arisings during the construction works as defined
below, the potential to cause adverse environmental impacts will be minimised.
Good Site Practices
3.5.4
Adverse impacts related
to waste management are not expected to arise, provided that good site
practices are strictly followed. Recommendations for good site practices
during the construction works include:
·
Nomination of an
approved person, such as a site manager, to be responsible for 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 proper waste management and chemical waste handling procedures;
·
Provision of sufficient
waste disposal points and regular collection for disposal;
·
Appropriate measures to
minimise windblown litter and dust during transportation of waste by either
covering trucks or by transporting wastes in enclosed containers;
·
Regular cleaning and
maintenance programme for drainage systems, sumps and oil interceptors;
·
A recording system for
the amount of wastes generated, recycled and disposed of (including the
disposal sites).
Waste Reduction Measures
3.5.5
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:
·
Sorting C&D waste
from construction activities to recover recyclable portions such as metals;
·
Segregation and storage
of different types of waste in different containers, skips or stockpiles to
enhance reuse or recycling of materials and their proper disposal;
·
Encouraging collection
of aluminium cans, PET bottles and paper by providing separate labelled bins to
enable these wastes to be segregated from other general refuse generated by the
work force;
·
Recycling any unused
chemicals or those with remaining functional capacity;
·
Proper storage and site
practices to minimise the potential for damage or contamination of construction
materials;
·
Planning and stocking
construction materials carefully to minimise amount of waste generated and
avoid unnecessary generation of waste.
3.5.6
In addition to the
above measures, specific mitigation measures are recommended below for the
identified waste arisings to minimise environmental impacts during handling,
transportation and disposal of these wastes.
Construction and Demolition Material
3.5.7
The C&D material
should be sorted on-site into inert C&D material (that is, public fill) and
C&D waste. The inert C&D material would require disposal to the
designated public fill reception facility. C&D waste, such as steel
and other metals should be re-used or recycled and, as a last resort, disposed
of to landfill. It is recommended that a suitable area be designated to
facilitate the sorting process and a temporary stockpiling area will be
required for the separated materials.
3.5.8
In order to monitor the
disposal of public fill and C&D waste at public filling facilities and
landfills, respectively, and to control fly tipping, a trip-ticket system
should be included as one of the contractual requirements and implemented by
the ET. The IEC should be responsible for auditing the results of the
system.
General Refuse
3.5.9
General refuse should be
stored in enclosed bins or compaction units separate from C&D
material. A licensed waste collector should be employed by the Contractor
to remove general refuse from the site, separately from C&D material.
Effective collection and storage methods (including enclosed and covered area)
of site wastes would be required to prevent waste materials from being blown
around by wind, wastewater discharge by flushing or leaching into the marine
environment, or creating odour nuisance or pest and vermin problem.
Chemical Wastes
3.5.10
After use, chemical
wastes (for example, cleaning fluids, solvents, lubrication oil and fuel)
should be handled according to the Code of Practice on the Packaging,
Labelling and Storage of Chemical Wastes. Spent chemicals should be
collected by a licensed collector for disposal at the CWTF or other licensed
facility, in accordance with the Waste Disposal (Chemical Waste) (General)
Regulation.
3.5.11
Table 3.4 provides a summary of the various
waste types likely to be generated during the construction works, together with
the recommended handling and disposal methods.

3.6
Land Contamination Impact
3.6.1
The Environmental Impact
Assessment (EIA) study has evaluated the potential land contamination issues
that may pose impacts on the construction of Sewage Pumping Station
(SPS). As indicated in the EIA study, no potential land contamination
associated with PS1, PS2, PS3, and PS1A is anticipated; however potential land
contamination concern in association with the previous landuse of the proposed
SPS in Site PS NPS would need to be addressed.
3.6.2
In view of the previous
potential contaminative land use of the Electrical and Mechanical Services
Department (EMSD) Sung Wong Toi Vehicle Maintenance Workshop, EMSD as the
current occupant should conduct a detailed land contamination assessment and
complete the necessary remediation prior to handing over the site to the
Government for construction of the proposed SPS at Site PS NPS. The land
contamination assessment should follow EPD’s “Guidance Note for Contaminated
Land Assessment and Remediation” and “Guidance Manual for Use of
Risk-based Remediation Goals for Contaminated Land Management” together
with the “Guidance Notes for Investigation and Remediation of Contaminated
Sites of Petrol Filling Stations, Boatyards and Car Repair /Dismantling
Workshop“. The implementation schedule of the recommended mitigation
measures is presented in Appendix
A2.
3.6.3
With proper
implementation and completion of the appropriate remediation action by EMSD for
the proposed SPS site at Site 5A1, further mitigation measures with regards to
land contamination would not be necessary for the construction and operation of
this project. Hence, no environmental monitoring and audit requirements
with regards to land contamination will be required for this project.
3.7
Impact on Cultural Heritage
3.7.1
The EIA Study concluded
that the sites of the proposed pumping stations are not in close proximity to
any of the existing built heritage resources and are not on any area of
archaeological potential, except PS3. For PS3, further
archaeological investigation and rescue excavation for the area around Trench
AA3 will be conducted as the mitigation recommendations for KTD. No
mitigation and monitoring and audit programme specific for cultural heritage
would be required for the construction of the proposed SPS.
3.8
Landscape and Visual Impact
3.8.1
The EIA has recommended
landscape and visual mitigation measures to be undertaken during both the
construction and operational phases of the project. This section outlines
the monitoring and audit of these measures.
3.8.3
The design,
implementation and maintenance of landscape and visual mitigation measures
should be checked to ensure that they are fully realised and that potential
conflicts between the proposed landscape measures and any other project works
and operational requirements are resolved at the earliest possible date and
without compromise to the intention of the mitigation measures.
3.8.4
Site inspection and
audit is necessary in the operation stage.

3.8.5
The mitigation measures
proposed within the EIA to mitigate the landscape and visual impacts of the scheme
should be embodied into the detailed engineering design and landscape design
drawings and contract documents. Designs should be checked to ensure that
the measures are fully incorporated and that potential conflicts with civil
engineering, geo-technical, structural, lighting, signage, drainage,
underground utility and operational requirements are resolved prior to
construction.
Construction
& Establishment Period
3.8.6
The implementation of
landscape construction works and subsequent maintenance operations during the
12-month establishment period must be supervised by fully qualified Landscape
Resident Site Staff (Registered Landscape Architect or Professional Member of
the Hong Kong Institute of landscape Architects).
3.8.7
Measures to mitigate
landscape and visual impacts during construction should be checked to ensure
compliance with the intended aims of the measures.
3.8.8
The progress of the engineering
works shall be regularly reviewed on site to identify the earliest practical
opportunities for the landscape works to be undertaken.
Baseline Monitoring
3.8.9
A one off survey shall
be conducted prior to commencement of any construction works. A photographic
record of the site at the time of the contractor’s possession of the site shall
be prepared by the Contractor and approved by the ER. The approved
photographic Record shall be submitted to the Project proponent, ET, IEC and
EPD for record.
Event/Action Plan for Landscape and
Visual Works
3.8.10 Should non-compliance of the
landscape and visual impacts occur, actions in accordance with the action plan
stated in Table 3.6 should be carried out.

Measures during Construction Phase
·
All existing trees should be carefully protected during
construction (CM1),
·
Trees unavoidably affected by the works should be
transplanted where practical. Detailed transplanting proposal will be

agreed prior to commencement of the work (CM2),
·
Control of night-time lighting (CM3),
·
Erection of decorative screen hoarding (CM4).
Landscape and Visual Mitigation
Measures during Operation Phase
·
Compensatory tree planting should be incorporated into
the proposed projects where trees are affected (OM1),
·
Tall buffer screen tree / shrub / climber planting
should be incorporated to soften hard engineering structures and facilities (OM2),
·
Aesthetically pleasing design as regard to the form,
material and finishes should be incorporated to all buildings, engineering
structures and associated infrastructure facilities (OM5).
