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. Other exceedances recorded were considered
non-projected related.

13.10 Environmental site inspections were conducted
on 4th, 9th, 18th, 25th
June 2021 by ET in the reporting month.
13.11 There were no environmental complaints,
no notification of summons or successful prosecutions received in the reporting
month.
13.12 The ET would keep track on the
EM&A programme to ensure compliance of
environmental requirements and the proper implementation of all necessary
mitigation measures.
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.
