(ASRs) |
The Assessment Area is
defined as an area within 500m from the boundaries of the Project site and
the work areas of the Project as stated in Section 3.4.4.2 of the EIA Study
Brief. A total of 44 ASRs (31
existing and 13 planned) have been identified in accordance with the criteria
in EIAO-TM Annex 12 and are illustrated in Figure 3.2. |
|
Assessment Methodology
and Criteria |
·
The principal
legislation for the management of air quality in Hong Kong is the Air
Pollution Control Ordinance (APCO) (Cap 311).
The AQOs implemented on 1 January 2022 have been used as the
assessment criteria for this assessment. ·
The measures
stipulated in the Air Pollution Control (Construction Dust) Regulation should
also be followed to ensure that any dust impacts are minimised. ·
Requirements
stipulated in the Air Pollution Control (Non-road
Mobile Machinery) (Emission) Regulation and Air pollution Control (Fuel
Restriction) Regulation will be followed to control potential emissions from
non-road mobile machinery. ·
As per Clause
3(ii) of Appendix B of the EIA Study Brief, qualitative assessment of the
construction dust impact has been carried out given that fugitive dust impact
associated with the construction of the Project are considered minor and not
expected to cause exceedance of relevant assessment criteria as stipulated in
the EIAO-TM and AQOs at nearby ASRs with dust control measures in place. ·
As per Clause 4(i) of the EIA Study Brief, a quantitative assessment has
been carried out to evaluate the operational air quality impact at the
identified ASRs. Cumulative NO2,
RSP, and FSP impacts, identified as the key air pollutants of concern during
operation phase, have been quantitatively assessed at the identified ASRs making reference to EPD’s Guidelines on Assessing the
‘Total’ Air Quality Impacts, taking into account Tier 1, Tier 2, and Tier 3
emission source contributions. |
|
Key Construction Impacts |
Minor roadworks, excavation
works slope works, etc. during the construction phase of the Project are
identified to be the potential dust generating activities. Considering the
limited extent of the works at any one time, no adverse dust impact arising
from the construction activities of the Project is anticipated with proper
implementation of dust control measures and good site practices. |
|
Key Operation Impacts |
Air quality impact would
arise from the vehicular emissions generated from the proposed roads of the
Project during operation phase. The
cumulative NO2, RSP, and FSP impacts at the identified ASRs comply
with the relevant AQOs during the operation phase of the Project. Adverse air quality impact arising from the
operation of the Project is not anticipated. |
|
Key Mitigation Measures |
Construction
Phase Dust control measures
stipulated in the Air Pollution Control (Construction Dust) Regulation and as
recommended in Section 3.8 will be implemented. Operation Phase No specific mitigation
measures are required during the operation phase. |
|
Residual Impact |
Construction
Phase With the implementation
of the recommended dust control measures and EM&A dust monitoring programme, no adverse residual impact is anticipated. Operation Phase No adverse residual
impact is anticipated during the operation phase. |
|
Compliance with EIAO-TM |
The potential air quality
impacts associated with construction and operation of the Project are in compliance with the EIAO-TM Annexes 4 and 12 and
applicable assessment standards/ criteria. |

Noise Sensitive Receivers
(NSRs) |
The Assessment Area is defined
as an area within 300m from the boundaries of the Project site and the work
areas of the Project as stated in Appendix C of the EIA Study Brief. A total of 23 NSRs (17
existing and 6 planned) have been identified in accordance with the criteria
in EIAO-TM Annex 13 and are illustrated in Figure 4.2 and Figure 4.3. |
|
Assessment Methodology
and Criteria |
Construction
Phase The methodology for the noise
impact assessment is in accordance with the procedures outlined in the GW-TM,
which is issued under the NCO and the EIAO-TM. Operation Phase Road traffic noise prediction is carried
out based on the traffic flows, following strictly the procedures stipulated
in the “Calculation of Road Traffic Noise (CRTN)” (1988) published by
Department of Transport, UK and EIAO Guidance Note No. 10/2010. |
|
Key Construction Impacts |
Potential sources of
noise impacts during the construction phase of the Project will mainly arise
from powered mechanical equipment (PME) operating at the construction work
sites. The construction noise
management plan (CNMP), which shall be prepared before tender invitation and
before commencement of construction of the Project, will contain an updated
quantitative construction noise impact assessment, direct mitigation
measures, quieter construction methods, and construction noise impact
monitoring and auditing program. |
|
Key Operation Impacts |
Road traffic noise would
be generated due to vehicular movement on the proposed Project roads during
operation phase. With the implementation
of the recommended noise mitigation measures, the predicted noise levels at
the identified representative NSRs would either comply with the traffic noise
criteria or that the noise contribution due to Project roads is less than 1.0
dB(A). Thus, adverse road traffic
noise impact arising from operation of the Project is not anticipated. |
|
Key Mitigation Measures |
Construction
Phase Mitigation measures such
as the use of quiet PME and temporary movable noise barriers are recommended
to minimise the noise impact at the affected NSRs
during non-restricted working hours. Movable noise barriers
have been proposed for some of the PME. The movable temporary noise barriers
should be located close to noisy plants and be moved iteratively with the
plant along a worksite as far as practicable.
The movable noise barriers should be a wooden framed barrier with a
small cantilevered upper portion of superficial density no less than 14kg/m2
on a skid footing with 25mm thick internal sound absorptive lining. Operation Phase ·

Installation of
acoustic windows at planned residential developments |
|
Residual Impact |
Construction
Phase With the implementation
of the proposed mitigation measures, the predicted noise levels at the
representative NSRs during construction phase would comply with the
construction noise criteria. No adverse residual noise impact is expected
during construction phase. Operation Phase With the implementation of
all the proposed direct noise mitigation measures, the noise contribution
from Project roads to the overall noise levels at all NSRs would be less than
1.0 dB(A) and the predicted noise levels due to Project roads at all NSRs
would comply with the relevant noise criteria. No adverse residual noise impact during
operation phase is anticipated. |
|
Compliance with EIAO-TM |
The potential noise
impacts associated with construction and operation of the Project are
acceptable. It is in
compliance with the EIAO-TM Annexes 5 and 13 and applicable assessment
standards/ criteria. |

Water Sensitive Receivers
(WSRs) |
In accordance with
Section 3.4.6.2 of the EIA Study Brief, the Assessment Area for the water
quality impact assessment includes areas within 500m from the boundary of the
Project site and covers the North Western and Deep
Bay WCZ under the WPCO. A total of 18
WSRs are identified, covering reservoir, watercourses, inactive fish ponds, and abandoned fish ponds. The identified existing WSRs are shown in Figure 5.1. |
|
Assessment Methodology
and Criteria |
The potential impacts due to the
construction of the Project were assessed following the EIAO-TM Annex 6
guidelines and the impacts evaluated based on the criteria in EIAO-TM Annex
14. Potential water quality impacts on
WSRs were evaluated according to the corresponding WQO criteria. |
|
Key Construction Impacts |
Wastewater may be
generated from the construction site runoff and construction activities. Sewage effluent from construction workforce
and runoff from work sites may be generated during the construction phase. Chemical wastes would also be produced from
the use of chemicals during construction.
Unacceptable water quality impact from the site runoff and
construction activities, sewage effluent from construction workforce, or
accidental spillage of chemicals/ chemical wastes is not expected provided
that the recommended mitigation measures are properly implemented. |
|
Key Operation Impacts |
Slight increase to road
runoff may be resulted from the proposed road works during operation. Such runoff typically contains elevated
levels of suspended solids, grits as well as trace amount of oil and grease
from vehicles, which could affect the water quality of the receiving
waters. With the implementation of
proposed mitigation measures and management practices (e.g., proper road drainage
system fitted with appropriate pollutant removal devices such as grit traps),
no unacceptable water quality impact associated with road runoff is expected. |
|
Key Mitigation Measures |
Construction
Phase Standard site practices
outlined in ProPECC PN 1/94 “Construction Site
Drainage” will be followed as far as practicable in order
to reduce surface runoff.
Relevant control measures from ETWB TCW No. 5/2005 Protection of
Natural Streams/Rivers from Adverse Impacts arising from Construction Works
should also be implemented where applicable to avoid adverse change in water
quality in the overflow channel. Sufficient number of chemical toilets should also be
provided and be regularly clean, maintained and emptied by licenced contractor. Operation Phase Drainage system should be fitted with
appropriate design measures to control pollution of drainage water. |
|
Residual Impact |
With the implementation
of the recommended mitigation measures, no adverse residual impact is
anticipated during the construction and operation phases. |
|

Construction
Phase A Waste Management Plan
(WMP) will be devised which incorporates recommended mitigation measures that
have been proposed to avoid or reduce potential adverse environmental impacts
associated with handling, collection, transport and
disposal of waste arising from the construction of this Project. 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 landfill and to
control fly-tipping. All dump trucks
should be equipped with GPS or equivalent system for monitoring of 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. Operation Phase ·

EPD as a chemical waste producer; ·
Store, recycle,
and collect chemical waste in accordance with the Waste Disposal (Chemical Waste)
(General) Regulation; ·
Provision of
adequate number of rubbish bins for collection of roadside littering; and ·
Frequent
clearing of bins by FEHD |
|
Residual Impact |
With the implementation
of the recommended mitigation measures, no adverse residual impact related to
waste management is anticipated during the construction and operation phases
of the Project. |

Assessment Methodology
and Criteria |
Land contamination assessment was
undertaken in accordance with the criteria set out in Annex 19 of the
EIAO-TM, as well as the following guiding documents: ·
Guidance Note
for Contaminated Land Assessment and Remediation (the RBRGs Guidance Note) ·
Guidance Manual
for Use of Risk-based Remediation Goals for Contaminated Land Management (the
RBRGs Guidance Manual); and ·
Practice Guide
for Investigation and Remediation of Contaminated Land (the Practice Guide). |
|
Key Construction Impacts |
·
Based on the
findings of the site appraisals in the form of desktop review and site
walkovers, there were 10 sites that had been identified with potential land
contamination concerns within the Project Area. Only one site, ie. site C10 is covered under this Project and site C1 to
C9 are under other Contractors. ·
As the concerned
area are still in operation and the construction works will not commence
until 2028, there could be change in site activities and land uses within the
Project Area prior to development which may cause further contamination
issues. Further site
appraisal, associated SI works, and any necessary remediation action
are recommended to be carried out after site operation has ceased but prior
to construction works at site C10. The
recommended further works, including the submission of Supplementary CAP(s),
CAR(s) / RAP(s) and RR(s), would need to follow EPD’s Guidance Manual, Guidance
Note and Practice Guide. ·
With the implementation
of the recommended further works, any soil / groundwater contamination would
be identified and properly treated prior to construction works. ·
Given the above,
land contamination impacts are therefore considered not insurmountable. |
|
Key Operation Impacts |
Land contamination impact
associated with the operation of the Project is not anticipated. |
|
Key Mitigation Measures |
No specific mitigation measure related to
land contamination is required during construction and operation phases. |
|
Residual Impact |
No adverse residual
impact in respect of land contamination within the Project site is expected. |
|

Key Construction Impacts |
Permanent loss of 1.8 ha plantation and 1.6
ha village fringe area which is considered of negligible to low potential
direct ecological impact. Given the large separation distance between
the Project and Hung Shui Kiu Egretry,
no disturbance impact to the egretry is
anticipated. Potential bat roosts on Chinese Fan-palm Livistona chinensis was recorded in the
close vicinity. Low to moderate ecological impact was anticipated. Avifauna and reptile species of
conservation importance recorded are highly mobile and versatile in habitat utilisation, and more suitable habitats are available
outside the Project Site, it is anticipated the impacts to avifauna and
reptile species of conservation importance is like the existing level due to everyday
heavy traffic. Impact to the semi-natural watercourses, as well as odonate and aquatic fauna species of conservation
importance are of low to moderate ecological impact. |
|
Key Operation Impacts |
In form of noise, light and dust, the
potential disturbance impact is expected to be insignificant. In form of runoff, downstream of all
watercourses identified along the YLH are channelized watercourse under
Drainage Services Department management. No impact is anticipated to the
semi-natural watercourse, which is located at higher elevation and separated
from the works area. There will be reprovision of noise barriers
along the road that may cause bird collision if not mitigated. However, it is
anticipated that the number of birds passing through is low due to the highly
disturbed nature, as recorded in the current study. The potential impact is
anticipated to be minor. The Hung Shui Kiu
egretry is located at highly disturbed area while
separated from the proposed works. Impacts from the Yuen Long Highway during
operation phase is expected to be negligible. Fauna sensitive to human
disturbance might have already avoided this area, while the existing species
might have already accommodated disturbance. Impact to flora and fauna
species of conservation importance found within the Assessment Area are
anticipated to be insignificant. |
|
Key Mitigation Measures |
Potential Disturbance from Construction
Works Water quality mitigation measures suggested
in the Water Quality Section should be followed to mitigate the potential
ecological caused by surface run-off during construction phase. Noise and construction dust control and
mitigation measures in the relevant sections shall be implemented to avoid
any indirect impact to adjacent habitats and wildlife. Potential Bird Collision Bird friendly design should be adopted for
the noise barriers, such as using falcon sticker and tinted materials. Use of transparent/reflective materials
should be avoided or minimized. Potential impact to potential bat roosts Any potential roosts in the close vicinity
of the works area (i.e. 50m) should be inspected by
a suitably qualified ecologist, prior to the commencement of works as a
precautionary measure. Suitable screening should be applied to separate
disturbance due to workers and/or noise from the potential bat roosts. Prior to the felling and/or transplanting
of trees, sites should be checked for the presence of bat roosts by a
suitably qualified ecologist. If roosts are found, any tree removal work
should be postponed until the roost is vacated. |
|
Residual Impact |
For habitat loss during
construction phase, the loss of developed area and plantation area will be
re-provided by the future roads and landscaping works. The residual impact of
habitat loss is considered acceptable. For indirect impact
related to noise, dust, run-off and other
anthropogenic activities, with the implementation of the recommended
mitigation measures, no adverse residual impact related to ecology is
anticipated during the construction and operation phases of the Project. |
|
Compliance with EIAO-TM |
The potential ecological
impacts associated with construction and operation of the Project are
acceptable. It is in
compliance with the EIAO-TM Annexes 8 and 16 and applicable assessment
standards/ criteria. |

proposed grading items and Government historic sites is identified within the
Project boundary and the 300m assessment area. Archaeology No Site of Archaeology Interest is identified
partly or wholly within the 300m assessment area. |
|
Assessment Methodology
and Criteria |
The study methodology follows the criteria and
guidelines as stated in Annexes 10 and 19 of the EIAO-TM as stated in the EIA
Study Brief. |
|
Key Construction Impacts |
Built Heritage There will be no construction works encroaching upon theses historical
structures. Hence, direct impact is not anticipated. Indirect impacts from
construction dust and vibration will also be negligible given the distances
to the works. No adverse impact is anticipated during construction phase. Archaeology No SAI is identified partly or wholly within the 300m assessment area.
It is anticipated that no SAI will be directly and indirectly affected by the
proposed road widening works due to their considerable distance from Yuen
Long Highway. The northern study area from “Planning and Engineering Study for
Housing Sites in Yuen Long South (YLS)-Investigation Environment Impact
Assessment” is falls partly within the 300m assessment area but it was
concluded in the survey that the northern area has low archaeological
potential. Furthermore, there would be no excavations works on the southern
side of the Project interfacing with the identified northern study area of
YLS-EIA. As such, no archaeological
potential impact would be anticipated. |
|
Key Operation Impacts |
Built Heritage and Archaeology As the operation of the Project involves no excavation works, no
cultural heritage impact from the Project is anticipated during operation
phase. Thus, no mitigation measure is
required during operation phase. |
|
Key Mitigation Measures |
Built Heritage As no declared monument, proposed monument, graded historic
sites/building/ structures, sites, buildings/ structures in the new list of
proposed grading items graded historic building and Government historic sites
would be affected by the road widening works of the Project, no mitigation
measure is required for these cultural heritage resources. Archaeology As no archaeology would be affected by the road widening works of the
Project, no mitigation measure is therefore required. As a precautionary measure, AMO should be informed immediately in case
of discovery of antiquities or supposed antiquities in the course of works,
so that appropriate mitigation measures, if needed, can be timely formulated
and implemented in agreement with AMO. |
|
Residual Impact |
No adverse residual
impact is anticipated |
|
Compliance with EIAO-TM |
The potential cultural
heritage impacts associated with construction and operation of the Project
are acceptable. It is in compliance with the EIAO-TM
Annexes 10 and 19 and applicable assessment standards/ criteria. |
13.3.1 The assessment of the potential environmental impacts associated with the construction and operation phases of the Project demonstrated that the implementation of the Project will not cause adverse or unacceptable environmental impacts in accordance with the requirements of the EIA Study Brief and criteria stipulated in the EIAO-TM.
