Silt screens are recommended to be deployed at the seawater intakes during the reclamation works period. Installation of silt screens at the seawater intake points may cause a potential for accumulation and trapping of pollutants, floating debris and refuse behind the silt screens and may lead to potential water quality deterioration at the seawater intake points. Major sources of pollutants and floating refuse include the runoff and storm water discharges from the nearby coastal areas.  As a mitigation measure to avoid the pollutant and refuse entrapment problems and to ensure that the impact monitoring results are representative, regular maintenance of the silt screens and refuse collection shall be performed at the monitoring stations at regular intervals on a daily basis.  The Contractor shall be responsible for keeping the water behind the silt screen free from floating rubbish and debris during the impact monitoring period.

Dredging of contaminated mud is recommended as a mitigation measures for control of operational odour impact from the Causeway Bay typhoon shelter. In recognition of the potential impacts caused by dredging activities close to the seawater intakes, only 1 small close grab dredger shall be operated within the typhoon shelter (for the dredging to mitigate odour impact) at any time to minimize the potential impact. Double silt curtains shall be deployed to fully enclose the closed grab dredger during the dredging operation. In addition, an impermeable barrier, suspended from a floating boom on the water surface and extended down to the seabed, shall be erected to isolate the adjacent intakes as much as possible from dredging activities.  For example, if dredging is to be carried out at the southwest corner of the typhoon shelter, physical barriers shall be erected to west of the cooling water intake for Excelsior Hotel  so that the intake would be shielded from most of the SS generated from the dredging operation to the west of the intake.  For area in close proximity of the cooling water intake point, the dredging rate shall be reduced as much as practicable.  Site audit and water quality monitoring shall be carried out at the seawater intakes during the dredging operations.  Daily monitoring of SS at the cooling water intake shall be carried out, and 24 hour monitoring of turbidity at the intakes shall be implemented during the dredging activities.   If the monitoring results indicate that the dredging operation has caused significant changes in water quality conditions at the seawater intakes, appropriate actions shall be taken to stop the dredging and mitigation measures such as slowing down the dredging rate shall be implemented.

In accordance with the ETWB TCW No. 34/2002, the contaminated material must be dredged and transported with great care.  The mitigation measures recommended in Section 5 of the EIA Report shall be incorporated.

Based on the biological screening results, the Category H (>10xLCEL) sediment which failed the biological testing would require Type 3 special disposal.  The volume of Category H sediment from the Causeway Bay typhoon shelter which would require special disposal arrangements is estimated to be approximately 0.05 Mm3.  A feasible containment method is proposed whereby the dredged sediments are sealed in geosynthetic containers and, at the disposal site, the containers would be dropped into the designated contaminated mud pit where they would be covered by further mud disposal and later by the mud pit capping, thereby meeting the requirements for fully confined mud disposal.

It will be the responsibility of the Contractor to satisfy the appropriate authorities that the contamination levels of the marine sediment to be dredged have been analysed and recorded.  According to the ETWB TCW No. 34/2002, this will involve the submission of a formal Sediment Quality Report to the DEP, at least 3 months prior to the dredging contract being tendered

During transportation and disposal of the dredged marine sediments requiring Type 1 and Type 2 disposal, the following measures shall be taken to minimise potential impacts on water quality:

 

 

 

 

 

 

 

 

 

·         Bottom opening of barges shall be fitted with tight fitting seals to prevent leakage of material.  Excess material shall be cleaned from the decks and exposed fittings of barges and hopper dredgers before the vessel is moved.

 

 

 

 

 

 

 

 

 

·          Monitoring of the barge loading shall be conducted to ensure that loss of material does not take place during transportation.  Transport barges or vessels shall be equipped with automatic self-monitoring devices as specified by the DEP.

 

·          Barges or hopper barges shall not be filled to a level that would cause the overflow of materials or sediment laden water during loading or transportation.

During soil remediation works, the Contractor for the excavation works shall take note of the following points for excavation:

·       Excavation profiles must be properly designed and executed;

·       In case the soil to be excavated is situated beneath the groundwater table, it may be necessary to lower the groundwater table by installing well points or similar means;

·       Quantities of soil to be excavated must be estimated;

·       It maybe necessary to split quantities of soil according to soil type, degree and nature of contamination.

·       Temporary storage of soil at intermediate depot or on-site maybe required.  The storage site shall include protection facilities for leaching into the ground. eg. Liner maybe required.

Air Quality Mitigation Measures

·       The loading, unloading, handling, transfer or storage of cement shall be carried out in an enclosed system.

·       The loading, unloading, handling, transfer or storage of other materials which may generate airborne dust emissions such as untreated soil and oversize materials sorted out from the screening plant and stabilized soil stockpiled in the designated handling area, shall be carried out in such a manner to prevent or minimise dust emissions. These materials shall be adequately wetted prior to and during the loading, unloading and handling operations.

·       All practicable measures, including speed controls for vehicles, shall be taken to prevent or minimize the dust emission caused by vehicle movement.

·       Tarpaulin or low permeable sheet shall be put on dusty vehicle loads transported between site locations.

 

 

 

 

 

 

 

 

 

 

 

 

 

Noise Mitigation Measures

·       The mixing facilities shall be sited as far as practicable to the nearby noise sensitive receivers.

·       Simultaneous operation of mixing facilities and other equipment shall be avoided.

·       Mixing process and other associated material handling activities shall be properly scheduled to minimise potential cumulative noise impact on the nearby noise sensitive receivers.

·       Construction Noise Permit shall be applied for the operation of powered mechanical equipment during restricted hours (if any).

 

 

 

 

 

 

 

 

 

Water Quality Mitigation Measures

·       Stockpile of untreated soil shall be covered as far as practicable to prevent the contaminated material from leaching out.  The leachate shall be discharged following the requirements of WPCO.

 

 

 

 

 

 

 

 

 

Waste Mitigation Measures

·       Treated oversize materials will be used as filling material for backfilling within the site.  Sorted materials of size smaller than 5 cm will be collected and transferred to the mixing plant for further decontamination treatment.

·       Stabilized soils shall be broken into suitable size for backfilling or reuse on site.

·       A high standard of housekeeping shall be maintained within the mixing plant area.

·       If necessary, there shall be clear and separated areas for stockpiling of untreated and treated materials.
