This Section
presents a summary of the key potential environmental outcomes associated with
the construction and operation of the Project. Implementation schedule of the
recommendations are shown in Table 10.1.
Given the small scale of the
construction works and separation distance from the Air Sensitive Receivers
(ASRs), the dust impact at ASRs is minimal. In addition, due to the small scale of
site area, the number of construction plant operating on site is limited,
therefore, the gaseous emissions from the construction equipment is minimal and
no adverse impact is anticipated.
In view of the limited emissions
from karts on tracks and separation distances between ASR and tracks, air
quality impact is not expected.
Since the number of shuttle bus running between the karting
track and Tuen Mun Centre,
the air quality impacts due to additional traffic arising from karting track would not be anticipated. Besides, with the proper handling of
petrol stores and re-fuelling and regular maintenance of karts, no odour
nuisance is expected.
Based on the impact assessment,
no EM&A measures are required.
Due to the large separation
distances, unmitigated construction activities associated with the Project will
not cause adverse noise impact at the NSRs. The predicted construction noise levels
are in the range of 35 – 37 dB(A), which complied with
the stipulated noise criterion.
Based on the worst case scenario
by adopting a maximum sound pressure level of 98 dB(A) at 1 m for 13-kart
movement, the predicted facade noise levels for a maximum of 40-kart event is
well below the daytime noise criterion of 55 dB(A) at all NSRs
located at more than 1km from the site boundary.
Based on the impact assessment,
no EM&A measures are required.
Given the small scale of the construction
works, short duration of construction period and no identified WSRs within the study area, water quality impacts are
negligible and minimal during construction phase of the Project.
For the operation of karting, the main concern is the water quality impact may
be caused by the servicing and petrol re-fuelling activities. Nevertheless, the surface runoff can be
well controlled by adoption of a proper drainage system with peripheral channel
and petrol interceptor. Addition to
the proper handling of petrol tank and re-fuelling and regular maintenance of
karts, no adverse water quality impacts are anticipated.
Based on the impact assessment,
no EM&A measures are required.
The anticipated quantities of
C&D materials to be generated from site clearance and building renovation,
and chemical wastes, sewage and general refuse to be generated during both the
construction and operational phases will be minimal. Minimal residual impacts are anticipated
from the construction and operation of the karting
track.
Given the small scale of the
construction works, short duration of construction period and minimal use of
heavy-duty construction machinery, fuel and oils, land contamination impacts
are negligible during construction phase of the Project.
For the operation of the Project,
the main concern is the potential land contaminations caused by the karting activities, servicing, repairing and oil filling
activities. Nevertheless, all the
above activities will be carried out on paved areas. Any leakage can be well controlled by
secondary containments or a proper drainage system with peripheral channel and
petrol interceptor. With
consideration of the infrequent refuelling activities and the minimal amount of
fuel handled each time, as well as proper handling of petrol tank, precaution
on refuelling activities and regular maintenance of karts, no adverse impacts
on land contamination are anticipated.
Based on the impact assessment,
no EM&A measures are required.
Given that the proposed karting track is selected to be located within a remote and
shielded area, the proposed karting track would be
only visible from limited viewpoints, including the transient road users along
No unacceptable
residual impacts are predicted for the construction and operation of the
Project. This section presents the
environmental outcome of the Project.
The
site at Lung Kwu Tan has been selected as the
preferred location for the development of an outdoor karting
track. The site is distant
(>1000m) from any existing and planned residential developments and hence
the potential air quality and noise impacts are anticipated to be small. As the site is currently a flatted
wasteland, no further tree felling or slope excavation is required and thus
minimise the impact on ecological resources.
The servicing area,
and repair/maintenance area would be properly paved by concrete to avoid any
potential land contamination impacts.
In addition, the village house and Tsz Tong
within the site boundary will be kept and managed by the Project Proponent.
As discussed in Section 10.8.1, the proposed karting track has avoided densely populated residential
developments. In addition, the
footprint of the karting track is designed such that
no slope cutting or tree felling are required as part of the construction
works. The karting
track location makes use of the existing vegetation and the natural topography,
so the Project would only be visible from limited viewpoints.
The EIA has
critically assessed the overall acceptability of any environmental impacts
likely to arise as a result of the construction and operation of the proposed karting track.
This EIA Study
has predicted that the Project will comply with all environmental standards and
legislation and thus demonstrated the acceptability of any residual impacts
from the Project and the protection of the population and environmentally
sensitive receivers. The Study
concluded that there would be no adverse long term or cumulative
effects/impacts on the environment.
