Water discharge |
The
complaint (ENPO-C0135) was received by HyD on 13 June
2018 and was referred by HyD to the ENPO. Then the
ENPO forwarded the complaint by email to the ET (Materialab
Consulants Ltd.) of the Contract No. HY/2013/03 on 25
June 2018. The complainant complained about the construction site of HZMB
artificial island. The construction site discharged muddy water into open
waters.
After
investigation, the ET of Contract No. HY/2013/03 (including Contract No.
HY/2013/06 within Contract No. HY/2013/03) concluded that the captioned
complaint is not related to the construction activities of our contract. Nevertheless,
the Contractor had been reminded to comply with the requirements stipulated in
the Environmental Mitigation Implementation Schedule (EMIS) of the EM&A
Manual, in particular:
• Water
Quality:
W2-
1.
wastewater from temporary site facilities should be
controlled to prevent direct discharge to surface or marine waters;
2.
storm drainage shall be directed to storm drains via
adequately designed sand/silt removal facilities such as sand traps, silt traps
and sediment basins. Channels, earth bunds or sand bag barriers should be
provided on site to properly direct stormwater to
such silt removal facilities. Catchpits and perimeter
channels should be constructed in advance of site formation works and
earthworks;
3.
silt removal facilities, channels and manholes shall
be maintained and any deposited silt and grit shall be removed regularly,
including specifically at the onset of and after each rainstorm;
4.
rainwater pumped out from trenches or foundation
excavations should be discharged into storm drains via silt removal facilities;
5.
measures should be taken to prevent the washout of
construction materials, soil, silt or debris into any drainage system;
6.
open stockpiles of construction materials (e.g.
aggregates and sand) on site should be covered with tarpaulin or similar fabric
during rainstorms;
7.
discharges of surface run-off into foul sewers must
always be prevented in order not to unduly overload the foul sewerage system;
8.
surface run-off from bunded
areas should pass through oil/grease traps prior to discharge to the stormwater system.
4.2.2
No notification of summons or
prosecutions was received during the reporting period.
4.2.3
Statistics
on notifications of summons and successful prosecutions are summarized in Appendix I.
