10 environmental monitoring and audit requirements
APPENDICES
Appendix 10.1 Project Implementation Schedule
10.1.1 This section further elaborates the requirements of environmental monitoring and audit (EM&A) for the construction and operation of the Project, based on the assessment results of various environmental issues.
10.1.2 The following sections summarise the recommended EM&A requirements with the Project Implementation Schedule presented in Appendix 10.1. Details of the EM&A programme and the specific monitoring requirements are presented in a stand-alone EM&A Manual.
Construction
Phase
10.2.1 With the implementation of the dust suppression measures stipulated in the Air Pollution Control (Construction Dust) Regulation, no adverse dust impact would be expected at the ASRs in the vicinity of the work fronts. Environmental site audit is recommended in the EM&A Manual to ensure that the dust control measures are implemented effectively. Details of the EM&A programme are provided in a stand-alone EM&A Manual.
Operation Phase
10.2.2 There will be no air pollutants emission during the operation of the Project. No adverse air quality impacts associated with the operation of the Project are expected, and thus no monitoring and audit programme would be required.
10.3.1 No existing and planned NSRs which rely on opened windows for ventilation is identified within the assessment area, it is predicted that there will be no adverse noise impact arising from the construction and operation of the Project. No environmental monitoring and audit for potential noise impact during the construction and operational phases is considered necessary.
Construction
Phase
10.4.1 With the implementation of the recommended water quality mitigation measures, no adverse water quality impact would be expected at the WSRs located in the vicinity of the work fronts. Water quality monitoring and site audit are recommended to ensure that all the recommended mitigation measures are properly implemented. Regular audit of the implementation of the recommended mitigation measures during the construction phase at the work areas should also be undertaken during the construction phase to ensure the recommended mitigation measures are properly implemented. Details of the water quality monitoring and audit programme and the Event and Action Plan are provided in the stand-alone EM&A Manual.
Operation Phase
10.4.2 No adverse hydrodynamic and water quality impacts associated with the operation of the Project are expected, and thus no monitoring and audit programme would be required.
Construction Phase
10.5.1 It is the contractorˇ¦s responsibility to ensure that all wastes produced during the construction of the Project are handled, stored and disposed of in accordance with the recommended good waste management practices and relevant legislation and waste management guidelines. Routine site inspection and audit would be conducted to check the implementation of the recommended good site practices and other waste management mitigation measures.
10.5.2 A Waste Management Plan (WMP) should be prepared and submitted to the Project Manager / Project Managerˇ¦s Representative of AAHK for approval. The recommended mitigation measures in this EIA Report should form the basis of the WMP.
Operation Phase
10.5.3 It is expected that there would be limited quantities of waste to be generated from the operation of the Project and no adverse environmental impacts is anticipated with the implementation of good waste management practices. Monitoring and audit programme for the operation phase of the Project would not be required.
Construction
Phase
10.6.1 Based upon a precautionary approach, a vessel speed limit of 10 knots should be strictly enforced on all construction-related vessels, so as to avoid vessel collision and minimise acoustic disturbance arising from fast ship movement to Chinese White Dolphins.
10.6.2
Water
quality monitoring and audit designed to detect and mitigate any unacceptable indirect
impact on water quality will also serve to proactively protect marine
ecological resource (e.g. coral colonies recorded at REA1 and REA3) against
water quality deterioration.
Regular site audits should be carried out to ensure the effective
implementation of mitigation measure stated in Sections 5.9.4 to
5.9.20.
Precautionary Measures
10.6.3 Translocation of the 23 coral colonies recorded at REA2 prior to any construction works is recommended as a precautionary measure. A detailed Coral Translocation Proposal, including description of methodology (e.g. pre-translocation survey, identification/ proposal of coral recipient site(s)) and post-translocation monitoring programme, should be prepared and subject to agreement with the authority before commencement of the coral translocation. All the precautionary pre-translocation survey, translocation exercises and precautionary post-translocation monitoring should be conducted by experienced marine ecologist(s) with at least 5 years relevant experience prior to commencement of construction works.
Operation Phase
10.6.4 Precautionary post-translocation coral monitoring surveys are proposed to be conducted on translocated corals at the recipient site. The results of the post-translocation monitoring should be reviewed with reference to findings of the pre-translocation survey and the data from original colonies at the recipient site.
Construction
Phase
10.7.1 The detailed landscape and engineering design of the Project shall be undertaken so as to ensure compliance with the landscape and visual mitigation measures described in Section 8.9.
10.7.2 A baseline review shall be undertaken at the commencement of the construction contracts to update the status of landscape resources, character areas and VSRs.
10.7.3 Implementation of the recommended mitigation measures would be regularly audited during construction phase. Details of EM&A requirement are discussed in the separate EM&A Manual.
Operation Phase
10.7.4 No EM&A requirement is considered necessary during the operational phase.
10.8.1 Since no impact on cultural heritage resource is anticipated, no environmental monitoring and audit during construction and operational phases is required.
