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

 

8.1.4     13 weekly Landscape and Visual Site audits were carried out on in the reporting period and 7 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). Total 5 no. of non-compliance was recorded in the weekly Landscape and Visual Site audits in the reporting period.

 

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

 

8.2         Comment and Recommendations

 

8.2.1     The recommended environmental mitigation measures, as proposed in the EIA reports and EM&A Manuals 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.

 

8.2.2     According to the environmental audit performed in the reporting period, the following recommendations were made:

 

Air Quality Impact

l   Open stockpiles shall be covered by unobtrusive sheeting to prevent dust emission.

l   Stock of more than 20 bags of cement or PFA should be covered entirely by impervious sheeting or placed in area sheltered on top and 3 sides.

l   Contractor was reminded to spray water during breaking or drilling to prevent dust emission.

 

Construction Noise Impact

l   Appropriate noise absorption material shall be used to wrap the breaker machine.

l   The door of the generator should be closed to reduce noise emission.

l   Impermeable sheeting shall be provided at the site boundary or repaired as necessary to reduce noise emission.

 

Water Quality Impact

l   Implement effective/preventive measures to prevent accumulation of stagnant water.

l   Surface runoff shall be prevented from entering the discharge channel directly. Sediment in the channel shall be cleaned up.

 

 

Chemical and Waste Management

l   Chemical and Waste Management shall be provided properly.

l   Construction waste shall be removed regularly.

l   Chemicals and lubricant shall be stored on drip tray properly. The hole of drip tray shall be sealed to prevent leakage of chemicals

l   Extra drip tray should be provided to prevent over storage of chemicals and fuel oil.

l   Different types of waste shall be segregated and stored in different containers, skips or stockpiles to enhance reuse or recycling of materials and their proper disposal.

l   The spilled oil shall be removed properly.

 

Landscape and Visual Impact

l   Open stockpiles shall be covered by unobtrusive sheeting to prevent dust and dirt spreading to adjacent landscape areas and vegetation, and to create a neat and tidy visual appearance.

 

Permit / Licenses

l   No specific observation was identified in the reporting period.
