Environmental Monitoring and Audit. 3.11.1 Environmental monitoring and audit are recommended for construction stage dust, noise, water quality and marine ecology, to check compliance with relevant statutory criteria and to ensure the effectiveness of the mitigation measures. Site inspection and audit are also recommended for waste management during construction and for implementation of landscaping measures during operation. Details of the recommended mitigation measures, monitoring procedures and locations are presented in a stand-alone Environmental Monitoring and Audit (EM&A) Manual. This will enable the Contractor to have early warning and provide necessary action to reduce impacts at specific areas if the critical assessment criteria are approached. The effectiveness of on-site control measures would also be evaluated through a monitoring exercise. All the recommended mitigation measures will be incorporated in an EM&A programme during implementation.
Environmental Monitoring and Audit. 8.9.1 As none of the heritage resources examined will be affected by this Project, no monitoring and audit programme specific for cultural heritage would be required.
Environmental Monitoring and Audit. 8.1 In accordance with the EIA, EM&A procedures are required during the design, construction and operation phases of the project implementation. The EM&A works during the design phase shall comprise an iterative audit process of specific design elements and the preparation of specifications. The following specification are recommended to be prepared during the design phase: ▪ bored piling monitoring programme; ▪ pre, during and post construction dolphin monitoring; ▪ 250m dolphin exclusion zone for use during dredging, reclamation, bored piling and sheet piling works; ▪ acoustic decoupling methods for use during reclamation and dredging works; ▪ marine vessel control specifications; ▪ deployment of an artificial reef; ▪ hoarding for protection of pitcher plants; ▪ coral translocation; ▪ design of toll plaza for grave G1 set back and protection; and ▪ landscape design.
Environmental Monitoring and Audit. 9.9.1 As water quality impact assessment suggested that change of water quality within the assessment area would be minor and acceptable during the construction phase and no ecological sensitive receivers was identified within the assessment area, no monitoring programme specific for marine ecology would be required.
Environmental Monitoring and Audit. 3.14.1 Details of the environmental monitoring and audit requirements are provided in Chapter 10 of this EIA and a stand-alone EM&A Manual.
Environmental Monitoring and Audit. An environmental monitoring and audit (EM&A programme) has been recommended for implementation during construction of the Project to ensure compliance with environmental legislation and standards during Project implementation. Monitoring of construction noise and water quality is recommended during construction of the Project to verify the effectiveness of the mitigation measures and to obtain a robust, defensible database of baseline information of noise and water quality before construction, and thereafter, to monitor any variation of noise and water quality from the baseline conditions and exceedances of relevant noise criteria and water quality objectives (WQOs) at the sensitive receivers during construction of the Project.
Environmental Monitoring and Audit. 6.10.1 With the implementation of the recommended air quality mitigation measures, good site practices, and dust and VOCs monitoring (including VOCs monitoring at biopiling discharge and ambient monitoring of VOCs at the site boundary) and audit programme, acceptable air quality impact would be expected at the ASRs during the decontamination process. Details of EM&A Programme are provided in the EM&A Manual.
Environmental Monitoring and Audit. 5.1.1 An environmental monitoring and audit (EM&A) programme was recommended for air quality, noise, water quality, waste management, and landscape and visual during construction phase. Site inspection/audit was also recommended to check the implementation of the air quality, noise, water quality, waste management, and landscape and visual mitigation measures during the construction phase. A summary of the EM&A requirements by each of the environmental parameters is presented in Table 5.1 below.

Environmental Monitoring and Audit. 3.11.1 An environmental monitoring and audit (EM&A) programme will be implemented during the construction and operation of the Project, to check the effectiveness of the recommended mitigation measures and compliance with relevant statutory criteria. The EM&A procedures are required during construction and operational phases of the project implementation. The EM&A requirements are divided into environmental monitoring and/or project auditing in the form of site inspection and supervision. Only monitoring for air and noise has been recommended but regular auditing for air, noise, water quality, ecology, LVIA and waste would be required.

Environmental Monitoring and Audit. 4.8.1 Waste management will be the contractor’s responsibility to ensure that all wastes produced during the decommissioning works are handled, stored and disposed of in accordance with good waste management practices and EPD’s regulations and requirements. The mitigation measures recommended in Section 4.6 should form the basis of the site Waste Management Plan to be developed by the contractor in the construction stage.
