7. CONCLUSION AND RECOMMENDATION

7.1 Conclusions

7.1.1 No Action and Limit Level exceedance was recorded for air quality monitoring and construction noise monitoring in the reporting period.

7.1.2 5 Action Level exceedance and 7 Limit Level exceedance were recorded for water quality in the reporting period. It was found that these exceedances were not project-related.

7.1.3 No Action / Limit exceedance was recorded for noise levels at stations (NMS1 and NMS2) in close proximity to the active ardeid night roosts in the monitoring period.

7.1.4 4 Action Level exceedances were noted for the ecological monitoring of birds during the reporting period, however, these exceedances were not project-related.

7.1.5 13 environmental site inspections and 13 landscape and visual site audits were carried out in the reporting period. Recommendations on mitigation measures were given to the Contractor for remediating the deficiencies identified during the site inspections.

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

7.1.7 The EM&A methodology has been effective in monitoring the environmental impacts of the Project and the effectiveness of the mitigation measures. The data collected were useful in determining whether the Project had caused unacceptable impacts on the sensitive receivers. Analysis of all EM&A data collected throughout the baseline and the impact periods demonstrated the environmental acceptability of the Project.

7.2 Comment and Recommendations

7.2.1 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.

7.2.2 According to the environmental site inspections performed in the reporting period, the following recommendations were provided:

Air Quality Impact

· No specific observation was identified in the reporting month. .

Construction Noise Impact

· The contractor was reminded to properly maintain the function of the noise barrier.

Water Quality Impact

· The contractor was reminded to properly cover the excavated material and trial trench.

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

· Enhance mitigation by providing sandbags along inner edge of U channel to prevent inflow of silty runoff.

· Silty deposit on road and in gullies should be cleaned.

· Mitigation measures (eg. sandbags / coverings) should be provided to prevent runoff from the temporary administration building works area flowing out to the nullah.

· Mitigation measure (eg. sandbags) should be provided at inlet / outlet of channel at catchpit to prevent discharge of water.

· Enhance the mitigation measure to prevent runoff flowing out to the nullah at area near temporary administration building.

· The contractor was reminded to provide mitigation measure to prevent silt / silty runoff getting into storm drain and / or checking the existing pipe network for temporarily sealing up manhole at excavation near piling area.

Chemical and Waste Management

· No specific observation was identified in the reporting month.

Land Contamination

· No specific observation was identified in the reporting month.

Landscape and Visual Impact

· Establish protective barrier for retain trees T250 & T251.

· Retain trees T252, T253 – Trench work within tree protection zone has to be reviewed and follow specification of works and exercise care when doing Work.

Permit/ Licenses

· The contractor was reminded to check availability of the Non-road Mobile Machinery (NRMM) label.
