14.1.1 This Project is to upgrade the existing
Tai O sewage collection, treatment and disposal facilities in Tai O and is classified
a Designated Project under Items F4, P.1
and Q.1 of Part I, Schedule 2 of the
EIAO.
14.2.2 Environmental benefits of the
environmental protection measures recommended: With the adoption of the
recommended mitigation measures, the potential environmental impacts associated
with the Project will be minimised to acceptable levels. There would be no
adverse residual environmental impacts.
14.2.3 Population and environmentally sensitive
area protected: The upgrading of Tai O STW will improve the quality of effluent
discharge from the existing Tai O STW as the existing sewage treatment process
will be upgraded from preliminary treatment to secondary treatment. The costal
water quality as well as the water quality sensitive receivers will be
improved.
14.2.4 Environmentally friendly designs
recommended: The proposed arising mains and sewer will run within the
residential areas of Tai O. To minimise the potential construction noise
impacts and public nuisances on the NSRs, it is recommended to adopt the hand
digging for soil excavation works of constructing sewer.
14.2.5 Key environmental problems avoided: The
objective of the upgrading works is to provide public sewers to all village
houses as far as possible and to upgrade the treatment level of Tai O STW from
primary treatment to secondary treatment so as to avoid deterioration of the
water quality of receiving water body. Upon the completion of the project, the
quality of effluent discharge from Tai O STW will be improved so the water
quality in the receiving water body will be improved.
14.2.6 Compensation areas include: There is no
significant habitat loss as a consequence of the Project. Thus there are no
specific compensation areas.
14.3.1 The EIA Report has provided an
assessment of the potential environmental impacts associated with the Project.
All environmental issues including air quality, noise, water quality waste
management, land contamination, ecology, fisheries, cultural heritage and
landscape and visual have been undertaken in accordance with the EIA Study
Brief (No. ESB-211/2009).
14.3.2 The nature and extent of different
environmental impacts arising from the construction and operation of the
proposed Project have been addressed and quantified in the previous sections.
In addition, a summary of assessment findings of these individual issues is
provided at the end of each section. Appropriate mitigation measures have also
been recommended for incorporation into the design, construction and operation
phases of the Project for compliance of relevant environmental legislation and
standards. The Implementation Schedules of the recommended mitigation measures
are provided in Section 13.
14.3.3 In conclusion, the Project would comply
with environmental legislation and standards with the implementation of the
recommended mitigation measures and good site practice. An EM&A programme
has also been recommended before and during the construction and operation
phases of the Project to check the implementation and effectiveness of the
recommended mitigation measures.
