Conclusions

 

13.1     This Monthly EM&A Report presents the EM&A work undertaken in June 2021 in accordance with Updated EM&A Manual.

 

13.2     One (1) Action Level exceedance and fifteen (15) Limit Level exceedances for dissolved oxygen, eight (8) Limit level exceedances for turbidity, seven (7) Limit Level exceedances for suspended solids and three (3) Action Level exceedance for arsenic of impact water quality monitoring were recorded. After investigation, three (3) Limit Level exceedances for dissolved oxygen, three (3) Limit level exceedances for turbidity and three (3) Limit Level exceedances for suspended solids at monitoring station, SHST-IS2, were found due to Contract No. ND/2019/04.

Recommendations                                                                              

 

13.13 According to the environmental audits performed in the reporting month, the following recommendations were made:

 

Air Quality Impact

·  To maintain the impervious material to entirely cover the stockpile of dusty materials;

·  To cover dusty stockpile with impervious materials;

·  To ensure all regulated machines displayed with valid Non-road Mobile Machinery (NRMM) labels; and

·  To keep public road near work site area clean and free of dust.

 

Construction Noise Impact

·  To operate compressor with doors closed; and

·  To provide noise barrier for noisy PME and operation.

 

Water Impact

·  To prevent any surface runoff discharge into nearby drainage or stream;

·  To enhance water mitigation measures on site runoff control, especially during rainy season;

·  To regularly review the capacity of sump pit for sediment control;

·  To ensure all vehicle clear of earth and mud before leaving site;

·  To divert all the water generated from construction site to de-silting facilities with enough handling capacity before discharge;

·  To ensure the drainage facilities would not be clogged with waste to avoid overflow;

·  To regularly check the condition of desilting materials for ensuring proper function.

·  To cover the exposed site area with tarpaulin to minimise muddy runoff during rainy season

 

Waste/Chemical Management

·  To dispose of general refuse properly;

·  To provide proper storage area for chemical storage; and

·  To maintain drip tray well.

 

Landscape & Visual Impact

·  Retained trees should be carefully protected.

 

Landfill Gas Hazard

·  No Smoking and No Naked Flame notices in Chinese and English should be posted prominently around the construction site.

 

Land Contamination

·  Stockpiling site(s) should be lined with impermeable sheeting and bunded. Stockpiles should be properly covered by impermeable sheeting to reduce dust emission during dry season or contaminated run-off during rainy season. Watering should be avoided on stockpiles of soil to minimize runoff.
