(c) to provide information on the consideration of alternatives to avoid and minimize the environmental impacts, in particular on the Tolo Harbour and Channel Water Control Zone and the Victoria Harbour Water Control Zone and to compare the environmental benefits and dis-benefits of each of the different alternatives;
(d) to identify and quantify emission sources and determine the significance of impacts on sensitive receivers and potential affected uses;
(e) to identify any potential impacts 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 waste management requirements and to propose measures to mitigate or prevent impacts;
(g) to evaluate the degree of risk of the landfill gas of Shuen Wan Landfill associated with the Project and to propose measures to mitigate the impacts;
(h) to propose the provision of mitigation measures so as to minimize pollution, environmental disturbance and nuisance during construction and operation of the Project;
(i) to identify, predict and evaluate the residual (i.e. after practicable mitigation) environmental impacts 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 these environmental impacts and reducing 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 in the Assignment, as well as the provision of any necessary modification; and
(l) to design and propose Environmental Monitoring and Audit (EM&A) requirements to ensure the implementation and the effectiveness of the environmental protection and pollution control measures.
(a) carry out necessary background studies to identify, collect and analyze existing information and the other on-going studies in the area relevant to the Assignment and in particular the findings of the Preliminary Project Feasibility Study for Tai Po Sewage Treatment Works- Stage V;
(b) identify all existing/ future land uses and sensitive receivers;
(c) carry out any necessary environmental surveys, site investigations and baseline monitoring works and make such investigations and inquiries as necessary for the satisfactory completion of the Assignment;
(d) quantify, by use of models or other predictive methods, the residual and cumulative environmental impacts (specifying whether these are transient, long term and/or irreversible) arising from the construction and operation of the Project;
(e) propose practicable, effective and enforceable methods, measures and standards to effectively mitigate any significant environmental impacts in the short and long term
(f) outline a programme by which the environmental impacts of the Project can be assessed, monitored and audited and.
(g) consult and liaise with all concerned authorities, including government departments and private organizations to obtain proper access, permits and consents.
· the air quality impacts arising from the construction, decommissioning /demolition, and operation of the Project;
·
the water
quality impacts arising from the construction, decommissioning /demolition, and
operation of the Project, in particular the impacts due to increased loading on
Victoria Harbour via the Kai Tak Nullah Outfall and impacts on Tolo Harbour and the
seawater intake of Tai Po Salt Water Pumping Station arising from
emergency discharge of sewage during construction and operation of the Project;
· the waste management for the construction and operation of the Project;
· the noise impacts arising from the construction and operation of the Project; and
· the landfill gas hazards associated with the proposed project.
Section 2 provides an overview of the Project outlining its key project requirements, site location and history, project design, works programme, as well as other related Projects in the area.
Section 3 presents an assessment of potential impacts to air quality during the construction and operational phases, especially the potential for the odour impacts to the sensitive receivers.
Section 4 presents an assessment of water quality impacts, in particular on the Tolo Harbour and Channel Water Control Zone and the Victoria Harbour Water Control Zone.
Section 5 presents an assessment of waste arising during the construction and operational phases. Key issues during the operational phase are identified as the management of sludge, grit and screenings and measures are proposed to mitigate or prevent impacts.
Sections 6 presents an assessment of Landfill Gas Hazards to evaluate the degree of risk to the Project of landfill gas associated with Shuen Wan Landfill, and to propose measures to mitigate the impacts.
Section 7 presents an assessment of noise impacts during both the construction and operation of the Project and recommends the control measures.
Section 8 presents the general requirements for environmental monitoring and audit (EM&A) during both the construction and operation of the Project.
Section 9 summaries the overall conclusions and key recommendations of the EIA Study.
Section 10 presents the implementation schedule of the proposed mitigation measures.
