Ÿ
Expansion of the sewage treatment capacity and
upgrading of the treatment level of the existing Cheung Chau Sewage Treatment
Works (STW);
Ÿ
Expansion of the pumping capacity of the
existing Pak She Sewage Pumping Station (SPS) and construction of a new SPS at
Kwun Yam Wan;
Ÿ
Upgrading of some existing sewers and
construction of some new sewers in various necessary locations in Cheung Chau;

DP / Non-DP |
Remarks |
|
Upgrading of Cheung Chau Sewage Treatment Works |
DP |
Expected
capacity exceeds 5000 m3 per day and located within 200 m from the
boundary of residential area.
Therefore it is classified as a DP according to Schedule 2 Part 1 Item
F.2 of the EIAO. |
|
Upgrading of Pak She Sewage Pumping Station |
DP |
Existing
capacity exceeds 2000 m3 per day and is located less than 150 m
from sensitive uses as stated in Schedule 2 Part 1 Item F.3(b)
of the EIAO. The SPS has been in operation
in 1984 which is before the enactment of the EIAO on 1 April 1998. It is a DP exempted under section 9(2) of
the EIAO. Proposed
upgrading works under this Project include replacement of screw pumps,
E&M equipments. No major civil works. |
|
Construction of Kwun Yam Wan Sewage Pumping Station |
Non-DP |
Expected
capacity would not exceed 2000 m3 per day. |
|
Sewers works |
Non-DP |
Sewers works
would not fall partly or wholly within any of the sensitive areas as stated
in Schedule 2 Part 1 Item Q.1 of the EIAO. |
|
Effluent reuse facilities within the Cheung Chau STW |
DP |
Schedule 2 Part
1 Item F.4 of the EIAO |
Ÿ
The overall acceptability of any adverse environmental
consequences that are likely to arise as a result of the proposed Project;
Ÿ
The conditions and requirements for the detailed
design, construction and operation of the proposed Project to mitigate against
adverse environmental consequences, as practicable; and
Ÿ
The acceptability of residual impacts after
implementation of the proposed mitigation measures.
(i)
to describe the Project and associated works
together with the requirements and environmental benefits for carrying out the
Project and the types of designated projects to be covered by the Project;
(ii)
to identify and describe elements of community
and environment likely to be affected by the Project and/or likely to cause
adverse impacts to the Project, including natural and man-made environment and
the associated environmental constraints;
(iii) to
provide information on the consideration of alternative options of the design,
layout, location, scale and extent of the Project and the construction methods
with a view to avoiding or minimizing potential environmental impacts to
environmentally sensitive areas and sensitive uses; to compare the
environmental benefits and disbenefits of different
options; to provide reasons for selecting the preferred option(s) and to
describe the part environmental factors played in the selection of preferred
option(s);
(iv) to
identify and quantify emission sources (including air quality, noise, water
quality and waste, etc. as appropriate) and determine the significance of
impacts on sensitive receivers and potential affected uses;
(v) to
identify and quantify any potential loss or damage and other potential impacts
to ecology and fisheries resources, flora, fauna and natural habitats and to
propose measures to mitigate these impacts;
(vi) to
identify and quantify where possible any potential landscape and visual impacts
and to propose measures to mitigate adverse impacts;
(vii) to
identify any negative impacts on historical and archaeological resources and to
propose measures to mitigate these impacts;
(viii) to
identify any potential human health impacts and to propose measures to mitigate
these impacts;
(ix) to
propose provision of mitigation measures so as to minimize pollution,
environmental disturbance and nuisance during construction and operation of
Project;
(x) to
investigate the feasibility, practicability, effectiveness and implications of
the proposed mitigation measures;
(xi) to
identify, predict and evaluate the residual environmental impacts (i.e. after
practicable mitigation) and the cumulative effects expected to arise during the
construction and operation phases of the Project in relation to the sensitive
receivers and potential affected uses;
(xii) to
identify, assess and specify methods, measures and standards, to be included in
the detailed design, construction and operation of the Project which are
necessary to mitigate these environmental impacts and cumulative effects and
reduce them to acceptable levels;
(xiii) to
investigate the extent of the secondary environmental impacts that may arise
from the proposed mitigation measures and to identify constraints associated
with the mitigation measures recommended in the EIA study, as well as the
provision of any necessary modification; and
(xiv) to design and specify environmental monitoring and audit
requirements to check the effective implementation of the recommended
environmental protection and pollution control measures.
