8.1               This section further elaborates the requirements of environmental monitoring and audit (EM&A) for the construction and operation phases of the Project, based on the assessment results of the various environmental issues. The objectives of carrying out EM&A for the Project include the following:


Ÿ             Provide a database against which any short or long term environmental impacts of the Project can be determined

Ÿ             Provide an early indication should any of the environmental control measures or practices fail to achieve the acceptable standards

Ÿ             Monitor the performance of the Project and the effectiveness of mitigation measures

Ÿ             Verify the environmental impacts predicted in the EIA study

Ÿ             Determine project compliance with regulatory requirements, standards and government policies

Ÿ             Take remedial action if unexpected problems or unacceptable impacts arise

Ÿ             Provide data to enable an environmental audit.


8.2               The following sections summarise the recommended EM&A requirements for the Project.  Details of the specific requirements are provided in a stand-alone EM&A Manual.


Air Quality


Construction Phase


8.3               In view of limited scale of construction sites, no adverse construction dust impacts would be expected with the implementation of the dust suppression measures stipulated in the Air Pollution Control (Construction Dust) Regulation and good site practices. Dust monitoring requirements are recommended in the EM&A Manual to ensure the efficacy of the control measures.  Details of the EM&A programme are provided in a stand-alone EM&A Manual.


Operational Phase


8.4               No adverse air quality impact on the representative ASRs would be identified during operational phase of the Project after re-diverting of some fresh air intakes at the Renaissance Harbour View Hotel, Hong Kong Convention and Exhibition Centre Phase I, and Grand Hyatt Hotel (ASRs A4, A5 and A6) to the new vent shaft provided for Atrium Link Extension. Notwithstanding this, post-project air quality monitoring is recommended to be carried out for the area underneath the Atrium Link Extension. Details of the monitoring requirements such as monitoring locations, frequency of impact monitoring are presented in the stand-alone EM&A Manual.


Noise Impact


Construction Phase


8.5               As the NSRs identified in this EIA are either centrally air-conditioned or located about 250m away from the project site, an adverse construction noise impact would not be anticipated. Notwithstanding this, appropriate noise control measures would be required in order to alleviate the noise impacts. Environmental audit during construction phase needs to be carried out to ensure that such mitigation measures would be properly implemented.


Operational Phase


8.6               No operation noise monitoring for fixed plant would be considered necessary.


Water Quality


Construction Phase


8.7               If monitoring of the treated effluent quality from land-based construction sites is required during the construction phase of the Project, the monitoring should be carried out by the relevant contractor in accordance with the WPCO license which is under the ambit of regional office (RO) of EPD. Detailed effluent sampling programme for water quality control during construction phase should be submitted by the relevant contractor to EPD for approval prior to commencement of the construction works. 


8.8               Water quality monitoring should also be carried out by the relevant contractor for the sea water intakes located within the ALE sea channel before the construction period and during the installation and removal of temporary marine piles. Monitoring parameters should include pH, turbidity, SS and DO.  A more detailed description of the water quality monitoring requirements is specified in the separate EM&A Manual.


Operational Phase


8.9               No adverse water quality impact would be expected during operation phase of the Project.  Requirement for water quality monitoring is considered not necessary.              



Waste Management


Construction Phase


8.10            Waste management would be the Contractor’s responsibility to ensure that all wastes produced during the construction of the Project are handled, stored and disposed of in accordance with good waste management practices and EPD’s regulations and requirements.


8.11            Waste materials generated during construction and demolition activities, such as C&D materials are recommended to be audited at regular intervals (at least quarterly) to ensure that proper storage, transportation and disposal practices are being implemented. This monitoring of waste management practices would ensure that these solid wastes generated during construction are not disposed into the nearby waters. The Contractor would be responsible for the implementation of any mitigation measures to minimize waste or redress problems arising from waste materials. A Waste Management Plan (WMP) should be prepared in accordance with ETWB TCB No.19/2005 and submitted to the Engineer for approval.


8.12            The large amount of C&D waste generated is mainly due to the piling works of large diameter piles’ excavation at the sea front site. If however marine sediment is found during pile excavation, the handling and disposal of such wastes will be managed in accordance with the requirements of the DASO and the current ETWB Tech. Circular no. 34/2002.


8.13            The recommended mitigation measures should form the basis of the site Waste Management Plan to be developed by the Contractor at the construction stage. The monitoring and auditing requirements of the WMP as detailed in ETWB TCW No.19/2005 should be followed with regard to the management of C&D material.


Operational Phase


8.14            It is unlikely the operation stage will cause adverse environmental impacts provided that statutory environmental requirements are fully compiled and good site practice is properly implemented.


Landscape and Visual Impact 


8.15            Landscape and Visual Impact Assessment in the EIA Report identifies the key issues and the assessed potential impacts due to the proposed work.  It also recommends mitigation measures for overall landscape and visual quality.  The main Contractor to be employed by TDC will be responsible for the implementation of all mitigation of measures.  Both TDC and the main Contractor will employ their own qualified landscape consultants in both construction and operation phases to ensure achievement of required quality for hard and soft proposals.


Construction Phase


Baseline Review


8.16            A baseline review shall be undertaken at the commencement of the construction contracts.  The purpose of the review is:

§          to check the status of the landscape resources within, and immediately adjacent to, the construction sites and works areas;

§          to determine whether any change has occurred to the status of the landscape resources since the EIA;

§          to determine whether amendments in the design of the landscape and visual mitigation measures are required for those changes; and,

§          to recommend any necessary amendments to the design of the landscape and visual mitigation measures.

Detail Design Phase


8.17            The landscape and visual mitigation measures shall be incorporated as soon as possible during detailed design stage, to ensure quality of visual and landscape mitigation aims as described in Table 7.7, Section 7 of EIA report.  Any changes to the mitigation measures that may be recommended as a result of the Baseline Review or ongoing Monitoring of the Design, Construction and Establishment Works shall be taken into account.


Landscape and Visual Monitoring


8.18            The design, implementation and maintenance of landscape and visual mitigation measures shall be checked bi-weekly to ensure that they are fully achieved.  Any potential conflicts between the proposed landscape measures and any other project works or operational requirements shall also be resolved in early stage, without compromising the intention of the mitigation measures.

Operational Phase


8.19            A registered landscape architect shall make monthly on-site visits to monitor all landscape and visual mitigation measures during the first year of the Operation Phase before handing over responsibility of maintenance to the HKCEC.
