8.            Conclusions


8.1.1     No Action and Limit Level exceedance for 24-hr TSP and noise was recorded in the reporting period at all monitoring stations.


8.1.2     No complaint of air quality was received. Therefore, no impact 1-hour TSP monitoring was conducted in the reporting period.


8.1.3     12 weekly environmental site inspections were carried out in the reporting period. Recommendations on mitigation measures on air quality, water quality, noise, waste management, land contamination and landscape and visual impact were given to the Contractor for remediating the deficiencies identified during the site inspections.


8.1.4     12 weekly Landscape and Visual Site audits were carried out on in the reporting period and 6 of them were carried out by a Registered Landscape Architect in the reporting period. The weekly Landscape and Visual Impact reports were counter-signed by IEC as according to the requirement of EM&A Manual (AEIAR-130/2009).

l   The load of dusty materials carried by vehicle leaving the site should be covered by impervious sheeting.

l   Broken concrete should be removed promptly.

l   Frequent watering on excavation area to suppress dust.


Construction Noise Impact

l   Acoustic fabric should be used while operating breaking tip.


Water Quality Impact

l   Construction runoff should be treated before flow into the drainage.

l   Debris and silt should be kept clear near the drainage opening.


Chemical and Waste Management
