11               Environmental Monitoring and Audit

11.1           Introduction

11.1.1       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. 

11.1.2       The following sections summarize the recommended EM&A requirements with the Project Implementation Schedule presented in Appendix 11.1.  Details of the EM&A programme and the specific monitoring requirements are presented in a stand-alone EM&A Manual.

11.2           Air Quality

Construction Phase

11.2.1       With the implementation of the dust suppression measures stipulated in the Air Pollution Control (Construction Dust) Regulation, good site practices and proposed mitigation measures, no adverse dust impact would be expected at the ASRs in the vicinity of the work fronts.  Regular hourly 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.

Operation Phase

11.2.2       No adverse air quality impacts associated with the operation of the Project are expected, and thus no monitoring and audit programme would be required.

11.3           Noise

Construction Phase

11.3.1       Construction noise impacts at the representative NSRs from the Project have been assessed in this EIA Report.  Appropriate mitigation measures are recommended to alleviate the impacts to meet the EIAO-TM criteria.  Noise monitoring during construction phase would be implemented to check the noise compliance with TM-EIAO criteria and the effectiveness of mitigation measures.  Details of the EM&A programme are provided in a stand-alone EM&A Manual.

Operation Phase

11.3.2       Prior to the operation of the respective staging of SHD Replanning Works and population intake of SHD Topside Development, noise commissioning tests should be conducted to check the compliance of the planned fixed plant noise source and railway noise.  Details of the commissioning tests and monitoring programme are provided in a stand-alone EM&A Manual.

11.4           Water Quality

Construction Phase

11.4.1       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.  Regular site inspections should be undertaken to inspect the construction activities and works areas in order to ensure the recommended mitigation measures are properly implemented.

Operation Phase

11.4.2       No adverse water quality impacts associated with the operation of the Project are expected, and thus no monitoring and audit programme would be required.

11.5           Sewerage and Sewage Treatment

11.5.1       With the implementation of the recommended precautionary measures to cater for the emergency situations, emergency discharge from the planned SPS is not expected and thus no adverse impact on water quality due to the emergency discharge is anticipated.

11.5.2       With the mitigation measures recommended in the EIA implemented, specific auditing during the operation phase of the Project is not required.

11.6           Waste Management

Construction Phase

11.6.1       It is 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 the recommended good waste management practices and relevant legislation and waste management guidelines.  Routine site inspections and auditing would be conducted to check the implementation of the recommended good site practices and other waste management mitigation measures.

11.6.2       A Waste Management Plan (WMP) should be prepared in accordance with ADV-19 and submitted to the Engineer for approval.  The recommended mitigation measures in this EIA Report should form the basis of the WMP. 

Operation Phase

11.6.3       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.

11.7           Land Contamination

11.7.1       Based on the site appraisal results, 9 facilities / areas (i.e. AB2, AB3, AB6, AB8, AB9, Transformers located outside AB11, AB16, AB22 and MDB) within existing SHD have been identified as potentially contaminated and require further site investigation.  However, the concerned areas are still in operation and undertaking the site investigation (SI) works at this stage is not feasible due to significant impact to the existing SHD operations, SI works are therefore recommended to carry out after decommissioning of the concerned area(s).  If necessary, any soil / groundwater contamination would be identified and properly treated according to the approved Remediation Action Plan(s) (RAP).  Remediation Report(s) (RRs) demonstrating the completion of remediation works at the area(s) (if any) confirmed with contamination will be prepared and submitted to EPD for approval prior to the commencement of construction works at the contaminated areas.

11.7.2       With the implementation of the recommended follow-up works for the concerned areas, any soil / groundwater contamination would be identified and properly treated prior to construction works at the concerned areas.  Specific EM&A requirement is therefore not required.

11.8           Landscape and Visual

Construction Phase

11.8.1       The design, implementation and maintenance of landscape and visual mitigation measures should be checked to ensure that they are incorporated in the detailed design.  Implementation of the applicable recommended mitigation measures shall be monitored through the site audit programme during the construction phase.

Operation Phase

11.8.2       As the operation landscape and visual mitigation measures would be provided during the construction phase, therefore no specific EM&A requirement is required during operation phase.

11.9           Hazard to Life

11.9.1       No adverse hazard to life impact is expected during the construction and operation of the Project, and thus no monitoring programme would be required.
