Measures to Mitigate Environmental Impacts from Site Run-off and Dredging During Construction
(a) Construction Runoff
(I) At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), the following shall be implemented:(i) sediment tanks of sufficient capacity to handle the predicted water flows shall be provided for settling out waste water prior to its disposal. The sediment tanks shall be constructed from pre-formed individual cells of approximately 6 to 8 m3 capacity. The system capacity shall be flexible and able to handle multiple inputs from a variety of sources including influent that is pumped;
(ii) all drainage facilities and erosion and sediment control structures shall be regularly inspected and maintained to ensure proper and efficient operation at all times and particularly following rainstorms. Deposited silt and grit shall be removed regularly and disposed of by spreading evenly over stable, vegetated areas;
(iii) open stockpiles of construction materials (for example, aggregates, sand and fill material) of more than 50 m3 shall be covered with tarpaulin or similar fabric during rainstorms. Measures shall be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system; and
(iv) all temporary and permanent drainage pipes and culverts provided to facilitate runoff discharge shall be designed for the controlled release of storm flows. All sediment traps shall be regularly cleaned and maintained. The temporary diverted drainage shall be reinstated to the original condition when the construction works have finished or the temporary diversion is no longer required.
(II) At all parts of the works areas and construction sites that may potentially experience spillages of oil or fuel associated with construction works, and throughout the full duration of the construction contract(s), oil interceptors shall be provided in the drainage system downstream of any oil/fuel pollution sources associated with construction. The oil interceptors shall be regularly emptied to prevent the release of oil and grease into the storm water drainage system after accidental spillages. The interceptor shall have a bypass to prevent flushing during periods of heavy rain.
(III) At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), existing drainage arrangements shall not be adversely affected during construction works, and any flow from the construction site must be diverted to settling traps/ponds before being discharged into the public drainage system.
(b) Dredging and Marine Disposal of Dredged Sediment
During dredging works associated with the construction of foundations for viaducts over the Shing Mun River, and Siu Lek Yuen and Tai Shui Hang Nullahs, the following mitigation measures shall be implemented to minimise the potential water quality impact during dredging:
(i) contaminated sediments shall be dredged using grabs of no more than 8 m3;
(ii) barges shall be fitted with tight fitting seals to their bottom openings to prevent leakage of material;
(iii) barge loading shall be accurate to avoid splashing dredged material into the surrounding water; and
(iv) construction works shall cause no visible foam, oil, grease, scum, litter or other objectionable matter to be present in the water within the site or dumping grounds;
(c) General Construction Activities
At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), debris and rubbish on site shall be handled and disposed of to avoid entering the water column and causing water quality impacts. Temporary on-site storage of excavated materials from station and depot construction works shall be covered with tarpaulin or similar fabric during rainstorms. Any washout of construction or excavated materials should be diverted to the drainage system via sediment traps. Stockpiling of the excavated material can be minimised by scheduling the construction programme in a way that one section of the alignment can be constructed and completed before the excavation works of the next section commence.
Measures to Mitigate Environmental Impacts from Construction Noise During Construction
Throughout the construction period of the Project, mitigation measures for specific construction activities at specific locations shall be implemented in accordance with the Tables 4.4s to 4.4.z and Table 4.4aa of the EIA Report. Corresponding mitigation measures for each construction activity to result in the lowest worst case maximum cumulative construction noise level indicated in the tables (right most column of the tables) shall be used. Mitigation measures "M1", "M2", and "M3" in the table are defined as follows:
M1 - item a below;
M2 - items a + b below;
M3 - items a + b + c below, where items a, b, c are defined as:
(a) Use of Quiet Plant and Working Methods
Throughout the full duration of the construction contract(s), models of plant that are quieter than those specified in the EPD's "Technical Memorandum on Noise from Construction Work in Designated Areas" shall be used.
(b) Temporary and Movable Noise Barriers
Throughout the full duration of the construction contract(s), movable barriers of 3 to 5 m height with a small cantilevered upper portion and skid footing shall be provided within a few metres of static plant (air compressor, water pump, generator, etc.) and within about 5 m of mobile equipment (excavators and mobile cranes, etc.) such that the line of sight is blocked by the barriers viewed from the noise sensitive receivers (NSRs).
(c) Reducing the Number of Plant Operating in Critical Areas Close to NSRs
The number of items of plant operating at the same time at the specified locations shall be minimized for each construction activity.
Measures to Mitigate Environmental Impacts from Waste Generation During Construction
At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), the following shall be implemented:
(i) develop procedures such as a ticketing system to facilitate tracking of marine mud and chemical waste, and to ensure that illegal disposal does not occur;
(ii) segregate and sort the waste materials into 3 categories:
- public fill (e.g. concrete and rubble) for re-use on-site or disposal at a public filling area;
- re-use and/or recycling waste (e.g. steel and other metals); and
- waste which cannot be re-used and/or recycled (e.g. wood, glass and plastic) for landfill disposal.
The sorting process shall be carefully monitored to avoid missing any of the 3 categories. Different types of wastes shall be stockpiled and stored in different containers / skips to enhance re-use or recycling of materials and their proper disposal; and
(iii) maintain records of the quantities of wastes generated and disposed off-site for each category of waste. Chemical waste that is produced, as defined by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation, shall be handled in accordance with "Code of Practice on the Packaging, Handling and Storage of Chemical Wastes" issued by the Environmental Protection Department (EPD).
Measures to Mitigate Landscape and Visual Impacts During Construction
At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), the following mitigation measures shall be implemented to minimise the landscape and visual impact of the construction works:
(i) control of night time lighting;
(ii) erection of decorative screen hoarding;
(iii) advance planting for screening;
(iv) minimising the height of temporary buildings;
(v) careful positioning of construction plant;
(vi) regular checks shall be carried out to ensure that the work site boundaries are not exceeded and that no damage is being caused to the surrounding areas;
(vii) temporary construction sites shall be restored to standards as good as, or better than, the original condition;
(viii) replanting of disturbed vegetation shall be undertaken and this shall use predominantly native plant species;
(ix) topsoil shall be stripped and stored for re-use in the construction of the soft landscape works;
(x) the locations of work sites associated with the proposed development shall be carefully selected to minimise the potential landscape and visual impacts of the proposed construction works; and
(xi) the potential for soil erosion shall be reduced at construction stage by minimising the extent of vegetation disturbance on site and by providing a protective cover (e.g. plastic sheeting or a grass cover established by hydroseeding) over any exposed ground.
Measures to Mitigate Environmental Impacts from Runoff During Operation
(a) along entire MOS alignment, a surface water drainage system shall be provided to collect track runoff. Where oils and lubricating fluids could be spilt, the track drainage channels discharge shall pass through oil interceptors and sediment traps to remove oil, grease and sediment before being diverted to the public storm water system;
(b) at stations, the depot and along the entire MOS alignment, silt traps, sediment basins and oil interceptors shall be designed to appropriate design standards, and whilst in use, regularly cleaned and maintained in good working order. The efficiency of these installations is dependent on regular cleaning and maintenance;
(c) at all areas with the potential for the generation of contaminated effluent long entire MOS alignment (particularly the depot), on-site drainage shall focus on areas where contaminated effluent may be generated and provide a clear segregation of clean and contaminated effluents; and
