Construction Site Runoff and
General Construction Activities ·
The practices outlined in ProPECC PN 1/94 Construction
Site Drainage should be adopted where applicable, to minimise the potential
water quality impacts from construction site runoff and various construction
activities. ·
There is a need to apply to EPD for a discharge licence
for discharging effluent from the construction site, if any. The discharge
quality is required to meet the requirements specified in the discharge
licence. Any wastewater generated from the works areas should be treated so
that it satisfies all the standards listed in the TM-DSS. It is anticipated that the wastewater
generated from the works areas, if any, would be of small quantity. ·
Good site practices should be adopted to collect the
rubbish and litter on the construction sites so as to prevent the rubbish and
litter from spreading from the site area.
It is recommended to clean the construction sites on a regular basis. ·
Scavenging service for collecting any materials/ waste
loss from the site into the sea should be provided on a need basis. |

Sewage from Workforce ·
The presence of construction workers generates
sewage. The construction workers can
make use of the existing toilet facilities within the MFT, as necessary. If
required, sufficient portable chemical toilets should be provided in the
works areas, and a licensed collector should be deployed for appropriate
disposal and maintenance of the toilets on a regular basis. ·
Notices should be posted at conspicuous locations to
remind the workers not to discharge any sewage or wastewater into the nearby
environment during the construction phase of the Project. Regular environmental audit on the
construction site can provide an effective control of any malpractices and
can achieve continual improvement of environmental performance on site. It is anticipated that sewage generation
during the construction phase of the Project would not cause water pollution
problem after undertaking all required measures. |

Accidental Spillage of Chemicals Any service shop and maintenance
facilities should be located within a bunded area, and sumps and oil
interceptors should be provided. Maintenance of equipment involving
activities with potential for leakage and spillage should only be undertaken
within the areas appropriately equipped to control these discharges. |
