12.1 Conclusions

12.1.1 1-hour TSP impact monitoring were carried out in the reporting month. No Action / Limit Level exceedance at AM1 and AM2 was recorded during the period.

12.1.2 Construction noise monitoring were carried out in the reporting month. No Action / Limit Level exceedance at CM1, CM2 and CM3 was recorded during the period.

12.1.3 No Action and Limit Level exceedance were recorded for water quality at M1, M2 and M3 in the reporting month.

12.1.4 Ardeid night roost monitoring was carried out in the reporting month. Of the two confirmed ardeid night roosts during the pre-construction survey, only ANR 1 was observed to be active. No Action / Limit Level exceedance at NMS1 and NMS2 was recorded during the period.

12.1.5 Ecological bird monitoring was carried out in the reporting month. One exceedance in Action Level was recorded for the ecological monitoring of birds on 15 & 20 September 2021. This was the significant decline in species abundance of all avifauna species for the point count method. However, the exceedance was not project-related.

12.1.6 Five environmental site inspections were carried out in the reporting month. Recommendations on mitigation measures for Permit/ Licenses were given to the Contractor for remediating the deficiencies identified during the site inspections.

12.1.7 Five landscape and visual site audits were carried out in the reporting month. Recommendations on mitigation measures for Permit/ Licenses were given to the Contractor for remediating the deficiencies identified during the site inspections.

12.1.8 Referring to the Contractor’s information, no environmental complaint, notification of summons and successful prosecution was received in the reporting month.

12.2 Comment and Recommendations

12.2.1 The recommended environmental mitigation measures, as proposed in the EIA report and EM&A Manual shall be effectively implemented to minimize the potential environmental impacts from the Project. The EM&A programme would effectively monitor the environmental impacts generated from the construction activities and ensure the proper implementation of mitigation measures.

12.2.2 According to the environmental site inspections performed in the reporting month, the following recommendations were provided:

Air Quality Impact

· The Contractor is reminded to cover the excavated soil properly with tarpaulin sheets to prevent dust emission for trial pit.

· Wind blown dust is observed when the truck is leaving at site exit. The Contractor should provide mitigation measures to prevent dust emission from vehicle wheel & body.

· The Contractor is required to improve the mitigation at present wheel wash area at southern exit (e.g. provide better bedding of aggregates for preventing muddy water).

Construction Noise Impact

· No specific observation was identified in the reporting month.

Water Quality Impact

· The Contractor is reminded to provide MSDS information at WetSep.

· Mitigation measures should be provided to intercept silty runoff from the piling area.

Chemical and Waste Management

· The Contractor is reminded to provide drip tray for the chemicals to prevent accidental spillage.

· The Contractor is reminded to cover the excavated soil properly with tarpaulin sheets to prevent dust emission.

Land Contamination

· No specific observation was identified in the reporting month.

Ecological Impact

· No specific observation was identified in the reporting month.

Landscape and Visual Impact

· No specific observation was identified in the reporting month.

Hazard to Life

· No specific observation was identified in the reporting month.

Permit/ Licenses

· No specific observation was identified in the reporting month.
