Implementation Status of Environmental Mitigation Measures

9.3 According to the EIA Report, EPs and the Updated EM&A Manual, the mitigation measures detailed in the documents are recommended to be implemented during the construction phase. An updated summary of the Environmental Mitigation Implementation Schedule is provided in Appendix M. The photographic records of measures as stipulated in EP to mitigate environmental impacts in the reporting month are presented in Table 9.3.

Table 9.3 Photographic Records and Implementation Status of Measures

EP No.	Condition	Photographic Record	Implementation Status
EP-468/2013/A	2.11	To minimise adverse impacts on habitats of ecological importance in the vicinity of the Project, 2m high solid dull green site barrier fences shall be erected around all active works areas.(Figure 12)	^^[1]
EP-473/2013/A	2.13	To minimise adverse impacts on habitats of ecological importance in the vicinity of the Project, 2m high solid dull green site barrier fences shall be erected around all active works areas.(Figure 14)	^^[1]
EP-475/2013/A	2.7	To minimise adverse impacts on habitats of ecological importance in the vicinity of the Project, 2m high solid dull green site barrier fences shall be erected around all active works areas.(Figure 15)	^^[1]
Implementation status:		^ Mitigation measure was fully implemented * Observation/reminder was made during site audit but improved/rectified by the contractor # Observation/reminder was made during site audit but not yet improved/ rectified by the contractor X Non-compliance of mitigation measure ¡P Non-compliance but rectified by the contractor N/A Not Applicable at this stage as no such site activities were conducted in the reporting period

[1]: Barrier fences might be subjected to change according to phasing plan designed at detailed design stage

9.4 Under EP-466/2013 (Condition 2.9), EP-467/2013/A (Condition 2.9), EP-469/2013 (Condition 2.7) to minimise adverse impacts on habitats of ecological importance in the vicinity of the Project, 2m high solid dull green site barrier fences shall be erected around all active works areas. As the Works programme under above EPs were still under preparation work and the barrier fences erection was still progressing in the Reporting Month, 2m high solid dull green site barrier fences will be checked once in place. The Hoarding Plan of the above EPs are shown in Figure 10, Figure 11 and Figure 13 respectively.

Solid and Liquid Waste Management Status

9.5 Waste generated from Contract No. ND/2019/01, ND/2019/02, ND/2019/03, ND/2019/05 and ND/2019/06 include inert construction and demolition (C&D) materials and non-inert C&D wastes in the Reporting Month.

9.6 The amount of wastes generated by the construction works of the Contract No. ND/2019/01, ND/2019/02, ND/2019/03, ND/2019/05 and Contract No. ND/2019/06 during the reporting month is shown in Appendix N.

9.7 The Contractors are advised to minimize the wastes generated through the recycling or reusing. All mitigation measures stipulated in the Updated EM&A Manual and waste management plans shall be fully implemented. The status of implementation of waste management and reduction measures are summited in Appendix M.
