This Section presents the
conclusions of the assessments undertaken for of the potential environment
impacts associated with the construction and operation of the Project.
This assessment has
predicted the construction noise impacts of the Project during normal daytime
working hours. With the use of
quiet PME, movable noise barriers and scheduling of PMEs/construction
activities, the predicted
construction noise levels arising from the Project at all representative NSRs will comply with the EIAO-TM construction noise criteria.
A construction noise
EM&A programme is recommended to check the compliance with the noise
criteria.
The potential road traffic noise impacts
have been assessed based on the worst year traffic forecast for Year 2026. With the provision of a 2.5m high
vertical noise barrier for the planned school, no
adverse noise impacts are predicted at the NSRs
during the operational phase of the Project as a result of the limited
traffic flow at the road sections within the meaning of Item A.1 of Schedule 2
under the EIAO. The traffic noise impact is considered
insignificant as the traffic noise level with the Project is not greater than
that without the Project at the design year by 1.0dB(A)
and the mitigated noise levels due to the road sections within the meaning of
Item A.1 of Schedule 2 under the EIAO
complied with the noise criteria as stipulated in the EIAO-TM.
Monitoring of road traffic noise is
recommended to confirm the results of the traffic noise impact assessment during
the first year after the operation of the Project.
In view
of limited scale of construction area, adverse dust impact at the ASRs is not
expected from the Project.
Appropriate dust control and suppression measures as stipulated in the Air Pollution Control (Construction Dust)
Regulation will be implemented to minimize any potential dust impact.
During operation, the vehicular emission sources
within the Study Area are dominated by road traffic on the proposed new road
sections and the existing road network including POR,
Water
quality impacts due to land-based construction, including road works, minor
slope modification works and construction of noise barriers, are mainly associated
with the surface runoff, effluent discharge from the site, and sewage from
on-site construction workers.
Impacts can be controlled to comply with WPCO-TM standards by implementing the recommended mitigation
measures. No unacceptable residual
impacts on water quality are anticipated.
It is
considered that impacts resulting from the operation of the Project, in terms
of water quality, will be minimal given that the Project will be designed with
adequate drainage systems.
11.5
Waste Management
Implications
Wastes
generated by the construction activities are likely to include C&D
material, general refuse from the workforce and chemical waste from the
maintenance of construction plant and equipment. Provided that these identified waste arisings are handled, transported and disposed of using
approved methods and that the recommended good site practices are strictly
followed, adverse environmental impacts are not expected during the
construction phase.
11.6
Landscape and Visual
Impact
Three Landscape Character Areas (LCAs) , LCA1 Miscellaneous
Rural Fringe Landscape, LCA2 Miscellaneous Urban Fringe Landscape, and LCA 3 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.
According to Annex 10
of the EIAO-TM, the landscape and
visual impacts are considered acceptable
with mitigation.
The
environmental impact assessment has concluded that no unacceptable
environmental impacts are envisaged as a result of the construction and operation
of the Project, provided that the recommended mitigation measures are
implemented.
