(a) The overall acceptability of any adverse environmental consequences that are likely to rise as a result of the Project.
(b) The conditions and requirements for the detailed design, construction and operation of the Project to mitigate against adverse environmental consequences wherever practicable.
(c) The acceptability of residual impacts after the proposed mitigation measures are implemented.
(a) To describe the Project and associated works together with the requirements for carrying out the Project.
(b) To consider alternatives including the location of the submarine outfall and emergency overflow, with a view to avoid and minimize the potential environmental impacts including impacts on coral communities; to compare environmental benefits and dis-benefits of each of the different options; to provide reasons for selecting the preferred option and to describe the part of environment.
(c) 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.
(d) To identify and quantify emission sources and determine the significance of impacts on sensitive receivers and potential affected uses.
(e) To identify and quantify any potential impact from point and non-point pollution sources on the identified water systems and sensitive receivers during the construction and operation stages.
(f) To identify and quantify any potential impact to marine ecology, including the coral communities, and to propose measures to mitigate these impacts.
(g) To propose the provision of mitigation measures so as to minimize pollution, environmental disturbance and nuisance during construction and operation of the Project.
(h) To investigate the feasibility, effectiveness and implications of the proposed mitigation measures.
(i) To identify, predict and evaluate the residual environmental impacts (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.
(j) 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 the identified environmental impacts and cumulative effects and reduce them to acceptable levels.
(k) 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.
(l) To design and specify environmental monitoring and audit requirements to ensure effective implementation of the recommended environmental protection and pollution control measures.
(a) The potential water quality impact and ecological impact, in particular the coral communities at the coast of Tai Lei Island during construction of submarine outfall and upgrading of the STW;
(b) The potential water quality impact and ecological impact, in particular the coral communities at the coast of Tai Lei Island due to outfall discharges; the discharge of untreated or partially treated sewage during emergency discharge arising from the operation of the STW;
(c) The potential odour and noise impacts associated with the construction, operation and demolition works of the sewage treatment works to the sensitive receivers; and
(d) The marine archaeological value of the area that may be affected by the Project.
