Good Site Practices
The site practices listed below should be
followed during construction works:
· Only well-maintained PME to be operated on site and should
be serviced regularly during construction · Silencers or mufflers on construction equipment should be
utilised (if appropriate) and should be properly maintained during the
construction; · Mobile plant, if any, should be sited as far away from
NSRs as possible · Machines and plant (such as trucks) that may be in
intermittent use should be shut down between work periods or should be
throttled down to a minimum · Plant known to emit noise strongly in one direction
should, wherever possible, be orientated to direct noise away from the nearby
NSRs · Material stockpiles and other structures should be effectively utilised, wherever practicable, in screening noise from on-site construction activities |

All effluent discharged from the construction site should comply with the standards stipulated in the Technical Memorandum on Standards for Effluents Discharged into Drainage and Sewerage Systems, Inland and Coastal Waters (TM-DSS). There is a need to apply to EPD
for a discharge licence for discharge of effluent from the construction site
under the WPCO. The discharge quality
must meet the requirements specified in the discharge licence. All the runoff and wastewater generated
from the works areas should be treated so that it satisfies all the standards
listed in the TM-DSS. If monitoring of
the treated effluent quality from the works areas is required during the
construction phase of the Project, the monitoring should be carried out in
accordance with the relevant WPCO licence.

Lighting along FTN under the revitalisation plan
should be minimised or incorporate wildlife-friendly lighting to avoid light
spill. Intensity of light should be controlled to the lowest level possible
and long wavelength lights such as amber lamps, which is visible to human but
invisible to most animals, are recommended. The lights should be installed
with a shield and at level as close to the ground as possible to prevent
extensive light casting up into the sky. Lights with motion sensors can also
be considered to further minimise disturbance to surrounding habitats as
lights that are not in use would be automatically turn off. |

Surface
Run-off / Irrigation Run-off · BMPs for storm water discharge and management as detailed below are recommended for the Project to mitigate potential adverse water quality impacts. · Good management measures such as regular cleaning and sweeping of road surface / open areas is suggested. The road surface / open area cleaning should also be carried out prior to occurrence of rainstorm. · Good management practices should be adopted to properly manage the water application rate and time during irrigation to minimise chance of run-off. Use of fertilisers and pesticides, if required, should be properly controlled, e.g. applications prior to forecasted heavy rain event should also be avoided to minimise the potential for run-off of residual fertiliser. In addition, use of more specific, systemic and biodegradable pesticide in low dosage is more preferred. Priority would be given to remove infected/sick plantings over the use of pesticides. The use and handling of fertilisers and pesticides should follow the Pesticide Ordinance and Code of Practice for the Safe and Proper Use of Pesticides in Public Areas by AFCD, Food and Health Bureau (FEHD) and Leisure and Cultural Services Department (LCSD). · Manholes, as well as storm water gullies, ditches provided among the development areas should be regularly inspected and cleaned (e.g. monthly). Additional inspection and cleansing should be carried out before forecast heavy rainfall. |

Routine
Maintenance Works The maintenance practices would be similar to the existing maintenance works undertaken by the DSD. The following considerations would be included in planning for the maintenance works: · Maintenance desilting of the nullah should be carried out on an annual basis during dry season (November to March) when the water flow is low, with the exception of during emergency situations where the accumulated silt would adversely affect the hydraulic capacity of the nullah or where flooding risk is imminent, or when complaints on environmental nuisance associated with the accumulated silt are received. Desilting should be carried out by hand-held or light machinery at low tide. · Phasing of the works should be considered to better control and reduce any impacts caused. Where possible, works should be carried out along half width of the drainage channel in short sections. A free passage along the drainage channel is necessary to avoid forming stagnant water in any phase of the works. · Containment structures (such as sandbags barrier) should be provided for the desilting works area to facilitate a dry or at least confined working area within the drainage channel. · The locations for the disposal of the removed materials should be identified and agreement sought with the relevant departments before commencement of the maintenance works. Temporary stockpile of waste materials should be located away from the channel and properly covered. These waste materials should be disposed of in a timely and appropriate manner. · Effective temporary flow diversion scheme should be implemented and the generated wastes should be collected and disposed off-site properly to avoid adversely affecting the water quality of the drainage system. |
