For water
quality, there are four Action Level and four Limit Level exceedances for suspended
solids were recorded. No Action/Limit Level exceedance for dissolved oxygen and
turbidity were recorded.
10.4 Dolphin transect survey
was carried out on 1st and 13th March 2017. No adverse
impact on Chinese White Dolphins was noticeable
from general observations.
10.5
Environmental
site inspection was conducted on 7th, 14th, 21st
and 28th March 2017 by ET in the reporting
month. All deficiencies
identified during the site inspection have already rectified / improved during
the follow-up audit session.
10.6
The
inspection to the Sha Lo Wan (West) Archaeological Site was conducted on 14th

storage of construction equipment was observed.
10.7
There was no environmental complaint, no notification of summons and successful prosecution
received in the reporting month.
10.8
The ET will
keep track on the EM&A programme to ensure compliance of environmental

According
to the environmental audit performed in the reporting month, the following recommendations were made:
Air Quality Impact
¡P
To regularly maintain the quality
of machinery
and vehicles on site.
¡P
To implement dust suppression measures on all haul roads,
stockpiles, dry surfaces and excavation works.
¡P
To provide
hoarding along
the entire length of that portion of the site boundary.
Noise Impact
¡P
To inspect the noise sources inside the site.
¡P
To space out noisy equipment and position the equipment as far
away as possible from sensitive receivers.
¡P
To provide temporary noise barriers for operations of noisy
equipment near the noise sensitive receivers, if
necessary.
Water Impact
¡P
To prevent
any surface runoff discharge into any stream course and sea.
¡P
To review
and implement temporary drainage system.
¡P
To identify
any wastewater discharges from site.
¡P
To ensure
properly maintenance for de-silting facilities.
¡P
To clear
the silt and sediment in the sedimentation tanks.
¡P
To review
the capacity of de-silting facilities for discharge.
¡P
To divert
all the water generated from construction site to de-silting facilities with
enough handling capacity before discharge.
¡P
To avoid accumulation of stagnant and ponding water on site.
Ecology Impact
¡P
To implement Spill
Response Plan in the event of accidental spillage of or other hazardous
chemicals.
¡P

implemented for air compressors and other noisy equipment mounted on
construction vessels according to acoustic decoupling measures plan.
Waste/Chemical Management
¡P
To check for any accumulation of waste materials or rubbish on
site.
¡P
To ensure the performance of sorting of
C&D materials at source (during generation);
¡P
To carry out inspection of dump truck
at site exit to ensure inert and non-inert C&D materials are properly
segregated before removing off site.
¡P
To avoid any discharge or accidental spillage of chemical waste or
oil directly from the site.
