2.5. SUMMARY OF MITIGATION MEASURES

26. 
    The project shall implement the following integrated approach to minimize the above predicted environmental and social impacts:
    

• 
  Avoidance: Alternative analysis has been regarded as one of the most important mitigation measures to minimize potential adverse environmental and social impacts. Minimizing land acquisition and resettlement to the extent possible has also been a key criterion for alignment selection during the feasibility and EA studies.
  
• 
  Sound engineering for design and construction: The project has been designed and will be implemented with state-of-the art engineering.
  
• 
  Comprehensive mitigation plans: detailed environmental management plan has been prepared.
  
• 
  Compliance framework: strict supervision and monitoring on implementation of mitigation measures during the construction phase.
  

27. 
    A detailed assessment of mitigation measures has been carried out along the alignment of the road. These measures are either:
    

(i) incorporated in project design and hence included in the bill of quantities;

(ii) included in the environmental specifications for contractors.

28. 
    In addition, site specific measures were identified for all sensitive areas along the road. The types of measures include: special culverts for irrigation canal crossings, lining of canals during construction, special crossings for community connectivity, pedestrian crossings (flyovers), relocation of pumping stations for irrigation, shifting of irrigation canals.
    
29. 
    Table 2 summarizes the sensitive areas and activities and the mitigation measures during the pre- construction and construction stages for specific sections of the road. These measures shall be incorporated in the environmental specifications for contractors and will be supervised by environmental supervision teams as part of the technical supervision of construction.
    

Table 2: Site Specific Mitigation Measures along the Bac Son – Nam Hai Road

Section (from Km to Km)	Sensitive Area or Activity	Mitigation Measures
0 – 1+400	Construction location of bridges crossing the Re river Construction of the road	- Establish storage, machinery repair and maintainance facilities at least 100m away from the river - Build ditches for collecting waste water from the site; excavate filled accumulated holes, etc. - Air and noise pollution control at dense populated areas - Discharging wastewater and solid waste into the river is prohibited.
	Rice fields, orchards and vegetable field areas	- Determine important periods (especially harvest time) to establish alternative temporary roads. - Limit the operation of transport vehicles during the indicated period. - Conduct surveys, dialogues and provide compensation for resulting effects on households (based on agreement with affected households).
1+400 –5+200	Near An Kim Hai canal	- Discharging wastes into the canal is prohibited
	Extra care is required in flower planting areas	- Intensify dust control measures at flower planting areas - Properly control and manage waste collection system
	The route near administrative areas (including schools, buidings of People Committees)	- Install fencing and signage system. - Heavy construction vehicles should be operated within short time frame and their use must be informed to the local authority prior to construction commencement. - Limit the travelling of transport vehicles at rush/peak hours. - Waste management - Proper dust, noise pollution control at dense populated areas.
	Rice fields and tree planting areas	- Determine important periods (especially harvest time) to establish alternative temporary roads. - Limit the operation of transport vehicles during this period. - Conduct surveys, dialogues and provide compensation for resulting effects on households (based on agreement with affected households).
5+200 –9+500	Position near Hoang Mai pagoda	- Special attention should be given to noice and dust prevention and mitigation measures
	Position near dykes before crossing rivers	- Pay attention to labour safety, especially in rainy and stormy weather - Frequently check the current situation of the dyke routes and make improvements and rectifications on cracks and other necessary places.
	Rice fields, orchard and vegetable areas	- Proper waste and soil erosion management - Conduct surveys, dialogues and provide personble compensation for negative effects on households (based on agreement with affected households)
9+500 –11+150	Crossing point at Truong Chinh Road	- Propose traffic control - Publicize construction time, install alternative temporary roads and bypasses, etc. - Signage system must be maintained and ensure adequate staff in charge of traffic control and presence of traffic police at construction times.
	Near the planned construction area of schools	When the construction site is being built and during construction, it is required to implement the following works: - Proper noice prevention - Properly apply safety methods and install fences, signs. - Limit construction at rush/peak hours. - Establish temporary roads and bypasses.
11+150 – 14+00	Near river embankment	Proper soil erosion and sedimentation control
	Near urban areas (resettlement area – Urban Upgrading Project) which are being constructed	- Apply construction methods in urban areas to avoiding construction at rush/peak hours, and provide sufficient warning signs. - Regularly check transport safety and emergency solving measures.
14+00 –15+550)	Dyke improvement position	- Pay attention to waterways safety management - Publicize construction time, alternatives of temporary roads and bypasses, etc. - Proper labour safety management (especially in stormy weather) - Regulate the stability of the dyke and immediately implement rectification methods for any cracks and arising damages.
15+550 –18+00	Location near Cat Bi Stabilization Reservoir	- Implement mitigation measures for surface water pollution (including river water and water of stabilization reservoir: do not discharge washing water of machinery and vehicles into the ditches/canals, establish waste water collection systems and build accumulation holes,).
	Route next to residential areas T3, T4 in Thanh To ward	- Apply proper construction methods in urban areas avoiding construction at rush/peak hours, providing enough warning signs. - Proper noise and air pollution control - Proper waste management
18+200 -19+870	Position near flower planting areas	- Proper dust control on flower planting areas - Properly install and and manage waste collection systems.
	Location near Kim Quang Tu Pagoda	- Special attention should be given to noise and dust control and suspension of construction activities during festival time.
	Location near planned residential areas	In case construction of these residential areas are completed and put into use before the completion of the road, it would be necessary to apply the same mitigation measures as in urban construction, including: installation of fences along the route, proper noise and dust control, establishing waste water collection system, frequently collect and treatwaste and rubbish, and not to keep or store them near residential areas.

    The above table is complemented by requirements for construction and operation included in environmental and social maps. These maps constitute a valuable tool for supervision of construction activities and will be referenced in all bidding documents and contracts. The maps are presented in Appendix 2.
