As required by the
EIA Study Brief, the documentation of Key Assessment assumptions, limitation of
assessment methodologies and related prior agreement(s) with the Director of
Environmental Protection have been prepared and are included in Appendix
14.1.
14.4
The findings of
this EIA study have determined the likely nature and extent of environmental
impacts predicted to arise from the construction and operation of the
Project. Environmental control measures
have been identified and recommended for the planning and design of the
Project, to achieve compliance with environmental legislation and
standards. The Implementation Schedule
listing the recommended mitigation measures are presented in Chapter 13.
Details of individual environmental aspects are summarised below.
14.5
The Project will
inevitably result in some landscape and visual impacts during construction and
operation phases. These impacts have
been minimizsed through careful consideration of
alternatives, minimization of works areas, incorporation
of aesthetic external designs and landscape treatments of proposed structures
which include
14.6
The Project is
located within the existing railway transport corridor network. Elements proposed under the Project will not
conflict with the planned landuse of the area nor
alter the planned continuous waterfront promenade proposed under the Hung Hom District Study.
It is considered that the Project would fit in well with the current and
future planning settings and would not conflict with statutory town plans of
the areas.
14.7
Approximately 640
existing trees will be affected by the proposed works, of which approximately
30 trees will be transplanted and approximately 610 trees will be felled. Many
of the affected trees are of heavy standard to mature size but none of these
are Registered Old and Valuable Trees. There are also no rare or endangered
species but only common species. Under the proposed scheme for the Project,
compensation for felled trees in accordance with Environment,
Transport and Works Bureau (ETWB) Technical Circular (Works) (TC(W)) No. 3/2006 - Tree Preservation will be planted in the reinstated
landscape areas. There will be no
permanently alienation of landscape areas.
All landscape areas which will be temporarily
alienated will be reinstated on a like to like basis after completion of
temporary works.
14.8
The road works
proposed for the Project, located in an area with character dominant by railway
development, is compatible with the existing landscape settings. There will be moderate impact on LCA06 – Hung
Hom Transportation Corridor LCA due to the
significant change in the character of the areas by the erection of large Noise
Mitigation Measures during construction phase.
With the aesthetic chromatic design to blend in the structures with the
adjacent landscape character, there will still be slight residual impact in Day
1 and Year 10 during operation.
14.9
Changes in the
visual context of the areas in the vicinity of the Project are
anticipated. There will be slight
adverse residual visual impact on the adjacent VSRs at high level during the
construction phase. With the
implementation of proposed mitigation measures for the proposed Noise Mitigation
Structures at Portal 1A, Cooling Tower, North and South Sides Ventilation
Shafts and realignment of Cheong Wan Road, the residual impact on adjacent VSRs
would be slight in Day 1 and Year 10 of Operation Phase.
14.10 Cumulative landscape and visual impacts during the construction and
operation phases from other concurrent projects which include the Shatin to
Central Link – Hung Hom to Admiralty Section [SCL (HUH-ADM)], Shatin to
Central Link – Tai Wai to Hung Hom Section [SCL (TAW-HUH)], Kwun Tong Line Extension (KTE)
were assessed. These concurrent projects
would not cause any insurmountable cumulative landscape and visual impacts.
14.11 As a whole, it is considered that the residual landscape and visual
impacts of the proposed Project is considered acceptable with mitigation
measures.
Construction Phase
14.12 Potential air quality impacts from the construction phase has been
assessed and the potential sources would mainly be related to construction dust
from excavation, spoil removal and wind erosion as well as materials handling
at barging point. A total of 14
representative air sensitive receivers (ASRs) have been identified within 500m
from the Project alignment and boundaries of all associated areas under the
Project.
14.13 Under the unmitigated scenario, the predicted cumulative maximum hourly,
daily and annual average Total Suspended Particulate (TSP) concentration at
most of the representative ASRs would exceed the criteria stipulated in
Technical Memorandum on Environmental Impact Assessment Ordinance (EIAO-TM) and Air Quality Objectives (AQO). Proper dust mitigation measures including
watering on active construction areas/haul roads; enclosing the unloading
process at barging point and the implementation of good site practices, were
thus proposed.
14.14 With the implementation of the recommended dust mitigation measures, the
predicted cumulative TSP concentration at all ASRs would comply with the
EIAO-TM hourly TSP criterion (500 µg/m3) as
well as AQO daily and annual TSP criteria (260 µg/m3 and 80 µg/m3).
Operation Phase
14.15 As the train will be electrically operated, air quality impact is
therefore not anticipated during operational phase. Besides, no adverse air quality impact is expected from the operation of
realigned Cheong Wan Road Viaduct and reduction in the number of diesel
locomotives (for
freight/maintenance trains/intercity) along the
existing East Rail Line (EAL). Exhausts
for general ventilation and smoke extraction facilities will also be carefully
positioned to avoid nuisance to the surrounding environment.
Construction Phase
14.16 Potential sources of noise from the construction of the
Project would mainly due to the use of powered mechanical equipment (PME) for
various construction activities such as construction of Cut-and-Cover tunnel
section and other supporting facilities for the Project. A total of 9 representative noise sensitive receivers (NSRs) have been
identified within 300m from the Project works area for construction noise
impact assessment.
14.17 Noise arising from the construction activities of the
Project would potentially have unavoidable impacts on the Noise Sensitive
Receivers (NSRs) located in the vicinity of the works areas. Without implementation of any mitigation
measures, the predicted construction noise levels at the most representative
NSRs would exceed the EIAO-TM.
14.18 Noise mitigation measures, including good site practices,
adoption of quieter plant, use of movable noise barriers and noise insulating
fabric, were therefore recommended to alleviate the noise impacts at the
representative NSRs due to nearby construction works. With the recommended mitigation measures in
place, the predicted construction noise levels due to the Project itself at all
representative NSRs would comply with the EIAO-TM daytime construction noise criterion at all NSRs.
14.19 Several concurrent projects would be conducted in the
vicinity of the Project, including SCL (HUH-ADM), SCL (TAW-HUH) and KTE.
Mitigated cumulative construction noise levels at the representative
NSRs are predicted and non-persistent 5 months exceedances of 1-4dB(A) and non-persistent 8 months exceedances of 1-3dB(A) would be found at
14.20
All practical
direct mitigation measures have been exhaustively investigated and the construction noise criteria have been met as far as practicable. The residual impacts have been minimised and are only temporary, reversible and unlikely to induce public health
concern and as such, are considered to be minor and acceptable.
Operation
Phase
14.21 The potential
operational noise sources identified in the Project would be from the
operation of trains in
the sections between
the Portal 1A and the
14.22 Rail noise exceedance is anticipated from the
Project at the Shun Man House North and South Blocks during Night-time. A 150m long natural ventilated noise
enclosure at Portal 1A has therefore been proposed in order to minimise the
exposure of NSRs to airborne noise. With
this enclosure, no adverse residual impact from the Project is anticipated.
14.23
Maximum
allowable sound power level emitted from louvers of fixed plants were
predicted. With the proper selection of
plant and adoption of acoustic treatment to meet the maximum allowable sound
power level, noise levels arising from the fixed plant of the Project at NSRs
would comply with the EIAO-TM criteria.
14.24 Construction
ground-borne noise impacts would mainly arise from the use of PME for excavation works and rock chiselling works for
diaphragm wall construction; while the transmitted noise from train operation
through the ground and structures in close proximity to tunnels may have
potential impact on NSRs. A total of 4
representative NSRs were identified for ground-borne noise assessment.
14.25 During
construction phase, predictions of ground-borne noise at the representative NSR
have been performed using the methodology recommended by the US Department of
Transportation. It was found that the predicted construction ground-borne noise
at representative NSR (Metropolis Residence) would comply with the noise
criteria stipulated in the EIAO.
14.26 During operation phase, predictions of ground-borne noise at the
representative NSR have been performed using the
methodology recommended by the US Department of Transportation. No exceedance of the ground-borne noise
criteria is anticipated at the NSRs due to a large setback distance of
90m. Thus, adverse impact from the
Project is not anticipated.
Construction Phase
14.27 The key water quality issue to arise during the construction phase is
the potential release of sediment-laden water from surface works areas and open
cut excavation. Minimisation of water
quality deterioration from land-based construction activities could be achieved
through implementing adequate mitigation measures. The site practices outlined in ProPECC PN 1/94 “Construction Site Drainage” should be
followed as far as practicable to minimise surface run-off and the chance of
erosion. With proper implementation of the recommended mitigation measures,
adverse water quality impact is not anticipated.
Operation
Phase
14.28 During operation phase, potential impacts to water quality are
anticipated to involve tunnel/station run-off and effluent discharges from the
HUH and general maintenance activities. With proper implementation of the
recommended mitigation measures, adverse water quality impact is not
anticipated.
Construction Phase
14.29
The
types of waste generated during construction phase of the Project would include
Construction and Demolition (C&D) materials from demolition, excavation and
site formation works, sediment, general refuse from workforce, and chemical
waste from the maintenance of construction plant and equipment. Implementation
of the proposed waste minimization, reuse, control and mitigation measures are
anticipated to minimise potential water quality, dust, odour, and noise impacts
associated with handling, transportation and disposal of the identified wastes
arising from the construction phase of the Project.
14.30
During
construction, it is estimated that approximately 386,000m3 of inert C&D
materials would be generated which is proposed to be reused offsite by other
projects (e.g. Hong Kong – Zhuhai –
14.31 The total volume of dredged/ excavated sediment generated from the
Project is estimated to be approximately 99,200m3. Based on the
results of the chemical and biological screening, approximately 62,200m3
of sediment is suitable for Type 1 – Open Sea Disposal and 37,000m3
of sediment requires Type 2 – Confined Marine Disposal in accordance with Environment, Transport and Works Bureau
Technical Circular (Works) No. 34/2002 - Management of Dredged/Excavated
Sediment
(ETWB TC(W) No. 34/2002).
14.32 With the implementation of the mitigation measures
recommended in accordance with the requirements of the ETWB TC(W) No.
34/2002, no adverse environmental impacts
would thus arise.
Operation Phase
14.33 The main waste types generated during the operation of the Project would
be general refuse (from the passengers, staff and any commercial operators),
chemical and industrial wastes (from the maintenance activities in stations,
ventilation shafts and railways). The
handling, collection, transportation and disposal practices of the identified
waste generated should follow the current practices at other operating railway
lines. Adverse impacts are not anticipated with
the implementation of good waste management practices.
14.34 An assessment of land contamination at the site has identified
construction workers to be the sensitive receivers during the construction
stage. A total of 231 soil and 20 groundwater samples had been collected at 34 locations identified as potentially contaminated sites and
analyzed per the Contamination Assessment Plan (CAP) and Supplementary CAP,
which were submitted and endorsed by the Environmental Protection
Department. Based on the analytical
results, no exceedances of the adopted Risk Based
Remediation Goals (RBRG) have been identified and therefore, remediation for
soil and groundwater is not required for investigation locations assessed.
Environmental Monitoring and Audit
14.35 An environmental monitoring and audit (EM&A) programme will be
implemented during the construction and operation of the Project to check the
effectiveness of the recommended mitigation measures and compliance with
relevant statutory criteria.
14.36 The EIA has been conducted based on the best and latest available
information during the course of the EIA study. The findings of this EIA have
provided information on the nature and extent of environmental impacts arising
from construction and operation of the Project.
The EIA has, where appropriate, identified mitigation measures to ensure
compliance with environmental legislation and standards.
14.37 Overall, this EIA has demonstrated general compliance with the environmental
standards and legislation with the implementation of the proposed mitigation
measures during the construction and operation phases. This EIA has also demonstrated general acceptability of the residual
impacts and thus the population and environmentally sensitive resources in the
vicinity of the site would be sufficiently protected. Environmental monitoring and audit mechanisms
have been recommended for the construction and operation of the Project, where
necessary, to verify the effectiveness of the
recommended mitigation measures. A summary of the environmental impacts
associated with the Project is presented in Table 14.1.

appropriate numbers of portable toilets shall be provided by a licensed
contractor to serve the construction workers over the construction site. Excavation
Activities The
construction programme should be properly planned to minimise soil excavation,
if any, in rainy seasons. Good site practices should be implemented. Diaphragm Wall The mitigation
measures as outlined in the ProPECC PN 1/94 should
be implemented. Groundwater
Seepages A cofferdam wall
should be built as necessary to
limit groundwater inflow to the excavation works areas. Groundwater
pumped out from the works areas or from dewatering process should be
discharged into the storm system via silt removal facilities. Change of Hydrology
and Groundwater Level Toe grouting should
be applied beneath the toe level of the temporary/permanent cofferdam walls
as necessary to lengthen the effective flow path of groundwater from outside
and thus control the amount of water inflow to the excavation. Recharge wells
should be installed as necessary outside the excavation areas. Water pumped from the excavation areas
should be recharge back into the ground. Suitable water
control strategies should initially adopt as far as practicable while
undertaking the excavation works. Barging Point |
