Environmental Impacts of the Project and Mitigation Measures
Mitigation Measure
•
Some part of excavation earth will be stored in the construction site to be used in stuffing. .Storage areas of
excavation earth will be determined before Works by applying the Local Authorities.
•
Remaining excavation earth and demolition wastes will be carried by licensed persons or companies to areas
designated by relevant municipalities.
•
Site specific Waste Management Plan will be prepared and implemented which will include, among the others,
planning and required permits on surplus excavation soil disposal area.
•
Vegetal topsoil stripped before excavation works will be temporarily stored in a suitable place in the construction
site, and transferred to the agricultural and pasture fields which is the local government will be allowed.
•
Topsoil will be recovered using appropriate equipment. Depending on compaction and recovery rates, deep ripping
may be required to maximize topsoil recovery with care taken not to mix topsoil with sodic subsoil. It should be arranged
that any excavated topsoil, where practical, shall be stored and reused. The more fertile topsoil will later be deposited to
form a superficial layer conducive to seedling establishment. The rest of topsoil shall be utilized for other purposes working
in coordination with local authorities and any other public interest to restore eroded land and/or re-forestation in the
vicinity of the route.
•
Sedimentation - Erosion Control and topsoil will be implemented properly.
•
Contaminated soils will be managed according to the regulations during excavation and handling of soils.
•
Cleared areas will be stabilized in order to avoid sediment release.
•
Excavated contaminated materials might be transported or stored in a safe manner on site, before their
transportation towards other sites.
•
Temporary occupied lands will be restored to their normal use after the completion of the construction Works.
•
In the event of any spoil or debris from construction works being deposited on adjacent land or any silt washed
down to any area, then all such spoil, debris or material and silt will be immediately removed and the affected land and
areas restored to their natural state.
•
Permit requirements will be identified for abnormal loads.
•
The routes will be identified with the estimated numbers of traffic movements, speed and times of travel.
•
The following speed limits must be respected, except emergency vehicles only at the time of emergency: 20 km/h
on the site roads; 10 km/h near and inside construction areas.
•
Dust and mud control will be identified.
•
The routes should pass through residential areas that ensure the safety of the community and minimize the
nuisance impact of traffic movements.
•
Existing road development plans will have been taken into account for route and road restoration plans.
•
Identification of the work shall be undertaken on the roads prior to construction activities, to upgrade or stabilize
the roads or any bridges or culverts to accommodate abnormal loads.
•
Road closures and diversions required will be identified and planned.
•
A traffic management plan will be prepared and implemented.
•
All long-term topsoil material stockpiles will be located outside the active construction site and away from
drainage lines. Drainage from higher areas will be diverted around stockpile areas to prevent erosion. As required,
sediment controls will be installed downstream of stockpile areas to collect any run-off.
•
Soil erosion will be controlled through use of dikes, fiber mats, mulches, grasses, slope, drains and other
devices.
•
A gutter or trough interceptor drain will be constructed at the top of the cut slopes to prevent the soil
erosion by precipitation.
•
Disturbance areas will be stripped progressively, as required, in order to reduce erosion and sediment
generation, to reduce the extent of topsoil stockpiles and to utilize stripped topsoil as soon as possible for
rehabilitation. Rehabilitation of disturbed areas, such as
•
roads, embankments, will be undertaken as soon as practicable after these structures are completed or
as areas are no longer required for operational purposes.
•
Sedimentation and Erosion Control, Top Soil Management will be detailed with management plans and
implemented.
•
Protection and renovation of ecosystem will be assured by studies.
•
A survey will be established to determine the location of all utilities affected by the Works.
•
Where either temporary or permanent works are to be undertaken in the vicinity of utilities appropriate
construction methods will be adopted to provide adequate protective devices and take precautionary measures,
in order to avoid damage to the utilities.
•
.
•
Regular and effective maintenance of construction machines will be made;
•
During the construction, background noise and vibration measurements will be carried out repeatedly and
measures will be taken such as sound barriers, mufflers of equipments, if necessary.

•
The plant and vehicles will be started-up sequentially rather than all together;
•
Reversing alarms will be used that do not have a tonal component (i.e. broadband), if necessary. In this type
of alarm, the sound energy would be spread homogenously across the frequency spectrum minimising the possibility of
acoustic feature in the reversing alarm.
•
Sources of significant noise will be enclosed, as far as reasonably possible; Loading and unloading should be
done away from noise-sensitive areas, where possible;
•
Any stationary plant will be located (i.e. pumps, compressor, concrete mixing, etc.) away from noise-sensitive
receptors, where possible.
•
Temporary local noise barriers will be installed for noisy equipment.
•
Low or non-vibratory piling equipment should be selected such as rotary or bored piling.
•
To reduce the requirement for vibratory compaction, use static force compaction, such as smooth-wheeled or
sheepsfoot rollers.
•
Vibratory plant not to be start up or shut-down within 50m of receptors.
•
