The major sensitive areas within the Study
Area include residential premises, wholesale market, hospital,
home for the aged and educational institutions. With the implementation of the proposed
mitigation measures, no adverse environmental impacts are expected at the air,
noise and water quality sensitive receivers within the Study Area during the
construction and operational phases of the Project. A summary of the key environmental
outcomes of the EIA Study and benefits of the environmental protection measures
recommended are presented in Table 9.1a.

Environmental Outcomes/Benefits |
|
The Project |
Requirements: ·
Construction of the 140m long single lane flyover with
410m and 100m long slip roads connecting from ground level to flyover and
from flyover back to ground level, respectively. ·
Construction of the 280m long slip road connecting the
southbound carriage of POF to the southbound carriageway of the ground level
section of YLH on the southern arm of POR. ·
Resurfacing and re-marking of two stretches of southbound
and northbound carriageways of the ground level section of YLH on the
northern arm of POR. ·
Construction of the 110m long segregated left-turn lane at
the northern arm of POR. ·
Construction of associated earth retaining structures,
slope works and works on environmental mitigation, landscape, drainage, road
lightings, water mains and traffic aids. Benefits: ·
The Project can relieve the traffic pressure and traffic
queues on the existing POR.
Potential consequences without the
Project: ·
Without the Project, the northern and southern approaches
of POR will further deteriorate and the tailback of traffic on the southbound
carriageway of the northern approach may block the through traffic from Tai Lam
Tunnel / NT North to Tuen Mun
/ Tin Shui Wai / ·
With traffic congestion at both ends of POR, there would be
consequential adverse air quality impacts to the nearby ASRs as the vehicles
are in idling condition in traffic congestion. |

Construction
Noise Impact |
Impact/Problem: · Unmitigated cumulative
construction noise level is up to 82 dB(A). Environmental benefits of
environmental protection measures recommended & Environmentally sensitive
areas protected: ·
Recommended mitigation measures: adopting quiet
construction plant, movable noise barriers and scheduling of PMEs/construction activities; and implementing good site
practices. ·
For the mitigated scenario, the predicted noise levels at
all representative NSRs comply with the daytime
construction noise standard as set out in the EIAO-TM. |
|
Road Traffic
Noise Impact |
Impact/Problem: · The traffic noise levels
with and without the Project at the design year are not increased by 1.0 dB(A). ·
No adverse traffic noise impacts are anticipated at the
existing and future ASRs with the provision of 2.5m high vertical noise
barrier for the planned school. |
|
Construction
Air Quality Impact |
Impact/Problem: · Potential dust nuisance. Environmental benefits of
environmental protection measures recommended: ·
Mitigation measures: implement
the Air Pollution Control (Construction Dust) Regulation and good site
practices. ·
No adverse air quality impacts are anticipated. |
|
Operational Air
Quality Impact |
Impact/Problem: No adverse
traffic emission impacts are anticipated at the existing and future ASRs. |
|
Construction
Water Quality Impact |
Impact/Problem: · General construction
activities associated with the construction of the Project could lead to site
runoff. Environmental benefits of
environmental protection measures recommended: ·
All of the recommended mitigation measures are implemented
and all construction site / work area discharges comply with the TM-DSS standards. ·
No unacceptable residual water quality impacts are
expected during the construction of the Project. |
|
Operational
Water Quality Impact |
Impact/Problem: · Adverse water quality
impacts associated with the operation of the Project are not expected at the
water sensitive receivers within the Study Area. Therefore, there will be no residual
impact associated with the operation of the Project. |
|
Waste
Management Implications |
Impact/Problem: ·
Wastes generated by construction
activities: general refuse from the workforce, chemical waste from plant and
equipment maintenance, and C&D material from excavation works and the
demolition of existing structures. Environmentally friendly designs recommended: ·
C&D material with suitable characteristics should be
reused on-site as far as practicable.
Surplus material would require disposal to a public fill reception
facility. Environmental
benefits of environmental protection measures recommended: ·
With the implementation of the recommended mitigation
measures and practices for the handling, transportation and disposal of the
identified waste arisings, no adverse environmental
impacts are expected. |
|
Landscape and
Visual Impact |
Impact/Problem: ·
Three Landscape Character Areas (LCAs) , LCA1 Miscellaneous Rural Fringe Landscape, LCA2
Miscellaneous Urban Fringe Landscape, and LCA3 Urban Peripheral Village
Landscapes, were identified. The residual
impacts on all three LCAs will be negligible. ·
A total of seven Landscape Resources (LRs)
, LR1 Roads, LR2 Agricultural Land, LR3 Roadside Plantation, LR4 Developed
Area, LR5 Disturbed Area, LR6 Nullah and LR7
Village, were identified. LR3
Roadside Plantation will experience moderate adverse and slight adverse
residual impacts during construction and operation respectively. However, there will be negligible
residual impacts on all other Landscape Resources. ·
Four Visually Sensitive Receivers (VSRs) , VSR1 Sun Yuen Long Centre, VSR2 Pok
Oi Hospital, VSR3 Kwong
Ming Ying Loi School and VSR4 Yeung
Uk Tsuen, were
identified. There will be
negligible residual impacts (impact at year 10) on all four VSRs. |
