·    Covering the stockpile areas of at least 70% area with tarpaulin sheet or impervious sheet;

·    Covering of dusty materials/spoils on trucks by impervious sheets;

·    Controlling the dropping height of fill materials;

·    Covering or storing all debris and materials in a sheltered debris collection area;

·    Storing dredged sediment in a separate enclosed tank; and

·    Providing wheel washing facility at each exit of the works site.

The following site practices should be followed during the construction of the Project:

·            Only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction phase;

·            Silencers or mufflers on construction equipment should be utilized and should be properly maintained during the construction phase;

·            Mobile plant, if any, should be sited as far 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;

Movable noise barriers of 3 m in height with skid footing should be used and located within a few metres of stationary plant and mobile plant such that the line of sight to the NSR is blocked by the barriers.  The length of the barrier should be at least five times greater than its height. With reference to A Practical Guide for the Reduction of Noise from Construction Works, the noise barrier material should have a superficial surface density of at least 7 kg m-2 and have no openings or gaps.

Cofferdam Demolition

 

During excavation, the following measures shall apply at all times:

·             Dry excavation will be used, as far as practicable, for cofferdam excavation.

·             Attention will be paid to the lifting speed of the grab to minimise the loss of sediment.

·             Excavated sediment will be disposed of in a gazetted marine disposal area in accordance with the Dumping at Sea Ordinance (DASO) permit conditions.

·             The marine vessels for transport of sediment to the marine dumping ground will be fitted with tight bottom seals in order to prevent leakage of material during transport.  The barges will be filled to a level that adequate freeboard is maintained to ensure that the decks are not washed by wave action.

·             The contractor(s) will confirm that the works cause no visible foam, oil, grease, litter or other objectionable matter to be present in the water within and adjacent to the excavation site.

·             For concurrent excavation works at adjacent work areas (ie Work Areas I and II, and Work Areas III and IV), construction will be carried out along the same flow direction (ie from upstream to downstream / downstream to upstream) to minimise the overall impacts to SS concentrations from adjacent work areas.

Ways to minimise generation of C&D materials include:

(i)             The Contractor is required to submit the Waste Management Plan (WMP) for approval by the Engineer with appropriate mitigation measures to deal with and allow space for waste segregation.  Different C&D materials should be sorted into different categories for re-use/recycle.  Day-to-day site operations of the Contractor should be closely monitored to ensure compliance with the approved WMP.

(ii)           The designer shall ensure that the design of levels and dimensions are reasonably accurate to avoid unnecessary demolition, excavation and fill.

(iii)          The Contractor shall be encouraged to use long lasting materials such as steel and poly-fibre for formwork on site.

(iv)          The RSS shall control the disposal of public fill and C&D waste to the designated public filling facilities and landfills respectively through the implementation of a trip-ticket system according to ETWB TC(W) No. 31/2004.

Ways to maximize the use of inert C&D material include:

(ii)           Different sections of works shall be programmed to ensure the C&D materials generated could be re-used by the other sections of works or works contracts.

(iii)          Temporary storage areas should be identified to resolve programming mismatch between excavation and filling works.

(iv)          The excavated soft inert C&D materials should be reused for backfilling the boundary patrol road, channel embankment, etc. whenever practicable.

Ways to maximise the re-use/recycle of C&D material and/or rock on site include:

(ii)           Segregation and storage of different types of waste in different containers, skips or stockpiles to enhance reuse or recycling of material and their proper disposal.  Prior to disposal of C&D waste, it is recommended that wood, steel and other metals be separated for re-use and/or recycling and inert waste utilized as fill material to minimize the quantity of waste to be disposed of at landfills.

MM9:

River Area Enhancement Landscaping – The river bed should be non-concreted as far as practical.  The River bank and margins of approximately 4.1 ha should be enhanced with vegetation to compensate for the loss of existing vegetation and to enhance the visual and landscape value of the river where slope gradient allows.  The typical design of riverbank landscaping areas for the Project is presented in Section 7.11.3 and Figure 7.11 of the EIA Report.  The overall objectives for the landscaping works will be mainly concerned with ecological enhancement but also include landscape enhancement.  For the sloping banks of the river, in order to guarantee safety of flood prevention, ecologically and environmentally friendly materials will be used as far as possible.  The preliminary proposed landscape treatment along the sloping river banks can be classified into three types: natural vegetation, semi-natural and artificial.  Further details of the river area enhancement plans can be found in Section 3 of the EIA Report, including protection of river bed with armour rock only where necessary and provision of grassed, cellular, reinforced concrete eco-friendly slope protection.  Eco-bags are made of UV-resistant Polyethylene gas filled with fiber soil.  Final details of the landscaping will be prepared during the detailed design stage of the Project..

Flood Retardation Pond - The flood retardation pond lies within the Shenzhen side of this Project.  It should be planted with suitable flora (both aquatic and, riparian) to enhance its landscape value.  Subject to the details design and planting plan, provision of wetland planting at the base of flood retardation pond will be provided as far as practical and technical feasible.  Final details of the landscaping will be prepared during the detailed design stage of the Project.

MM11:

Floodplain Areas - The areas bound by sharp turns in the natural meander of the river should be made into floodplain areas to retain some of the riparian landscape at the river margins.  The overall objectives for the landscaping works will be mainly concerned with ecological enhancement but also include landscape enhancement (also refer to Section 7.11.3 of the EIA Report).  Further details will be developed during Detailed Design Stage.

Colours of Structures - Colours for the structures eg fences should be chosen to complement the surrounding area.  Lighter colours such as shades of light grey, off-white and light brown may be utilised where technically feasible to reduce the visibility of the structures.
