2.3. NATURAL CONDITION OF THE SUBPROJECT'S AREA
1. Climate and topography The subproject's area is characterized by tropical monsoon climate region which
has 2 different seasons: + Dry season: from October to the next Match
+ Rain season: from April to November.
Transmission line and transformer station
Air temperature changes clearly due to different terrain. The annual average air
temperature ranges from 17 to 2 0 ' ~ . The absolute maximum of air temperature is
30.2"C and the absolute minimum of air temperature is 1°C. Annual rainfall average:
2,548 mm.
Can Ho hydropower subproject on Phin Ho stream has catchment area of 32.2 km2. Flood season starts on June and ends on November which made up to 65% of annual flow.
transformer station
Transmission line
Almost of the subproject's catchment area is a distinctive mountain zone which has its own unique features. Landslide is common event and becomes one of the biggest environmental trouble in this area as consequence of forest destruction.
2. Natural terrestrial features
35kV* 1 station
35kV; 0.4kV
Forests and forest land account for 81 % of Sapa's total land area. Hoang Lien primeval forest are home to many kinds of value plants and rare animals (black gibbon, weasel, black panther, bear ect and strictly protected. Can Ho hydropower subproject is far from Hoang Lien primeval forest about 15 to 18 krn. However, forest in the subproject's area has been reduced due to forest degradation, land use for cultivation. As results of these, the environment has been negatively changed for terrestrial animals and many forest animals have not been seen for the last decades.
4 k m x lorn
3. Aquatic features
In contrast to terrestrial features, aquatic ecosystem in the subproject's catchment area is very poor although having high stream density but not comfortable for aquatic features living. The main reasons for that are: water temperature is alway low, sloping stream.
2.4. SOCIAL CONDITION
The subproject's area is dominated by ethnic Dao people, however, very thinly populated on mountain side. According to the annual report of Ban Khoang's people committee, poverty households, which income is below 200,00OVND/person-month, make up to 25-30%. Their life mainly depends on rice, corn and cassava cultivation and forestry. However, almost of cultivated land is one-crop seedling, low productivity and always faces natural calamities (flood, drought, insect...). About 50% children is not compulsory primary education as consequence of low living standard, backward custom, poor traffic system ect.

Chapter 3: KEY ENVIROMENTAL IMPACTS
3.1. Construction phase
I . Loss of land: The development of Can Ho hydropower subproject causes losing parts of the
land due to acquisition. 101 ,800m2 of land will be acquired for construction works, in which 23,500m2 is fallow hilly land, 14,800m2 is one-crop rice land, and 63,500m2 is burnt-over land (corn, cassava). Details for each type of acquired land are as described on the following tables:

There are 22 households of Lu Khau village and Can Ho village will lose cultivated land (78,300m2), most of which is one-crop rice land and burnt-over land growing corn, cassava.
10 1,800
2. Impacts of construction inert waste:
50,000
~ n e - ~ r o ~ rice land (m2)
Includes excess rock and spoil, soil material, concrete. This type of waste may cause erosion, sedimentation, muddy stream water, impoverished soil, land occupancy ect.
15 1 ,800m2
3. Vegetation waste from removal of the reservoir and construction site:
Burnt-over land (m2)
Vegetation debris can lead to bush fire. Additionaly, vegetation debris is disintegrated produces organic contaminants causing surface water pollution.
Fallow hilly land (m2)
4. Erosion and sedimentation:
Erosion and sedimentation are as consequences of level the ground, clear plants
and grass. Because of local natural condition, erosion can cause landslide, affect to traffic system and agriculral land.
5. Air pollution:
Construction engine equipment exhausts contain several air pollutants such as: CO, NOx, SO2, volatile organic substances, dust. These pollutants will affect to workers and local people.
6. Impacts of noise.
High level noise is generated from operation of construction engine equipment, trucks, concret maker, macadam grinding. Noise level may reach to 80-90dBA at construction sites and impact to workers and local people.
7. Dust
This impact will be serious in dry season. Concentration of dust in the air at construction site, along access road can reach to hundreds mg/m3.
8. Sewage and grey water.
Sewage normaly contains big amount of organic components and has very high concentration of BOD5, COD, N-contained substaces, P-contained substaces. Additionaly, there are dozen of harmful bacterium like: e.coli, colifonn.
9. Solid wastes
Similar to sewage, solid waste is one of the enviromental pollution sources based on organic contaminants and harmful1 bacterium.
10. Hazardous materials (fuels, lubricants, explosives etc).
Risks of hazardous materials may cause serious consequences to human, ecosystems, enviroment and properties, especialy, fuel spill.
11. Affect to the local traffic svstems
Damage road, traffic jam due to increase trasportation means, traffic accident ect.
12. Impact to flora and fauna .
Degration of evergreen and semi- deciduous forests may occur when timber is used for construction camps, uncontrolled collection of firewood and bushfire as resuls of using firewood. Workers may trap and hunt animals, especialy catch fish by electric equipments.
13. Human health
Enviroment polluted by dust, noise, engine exhausts, sewage arid grey water, solid waste can impact to workers and local people health by causing various diseases. Morover, workers may suffer from malaria (one of very popular diseases in outback of Northern Vietnam), diarrhoea, petechial fever, bird flu (H5N1) as well as sexual tranmision diseases include HIVIAids.
14. Enviromental risks include
Diseases spread, landslide, flood, hazardous materials usages and storage, unexplosives, struck by lightning ect.
15. Chance find of cultural artifacts, and areas/structures of local cultural value.
The project's area used to be primeval forest. People have moved to live around these sites not for long time (about last 30 years) as shifting cultivation of wandering hill tribes custom of Dao ethnic people. So that, it is unnecessary to do archaeological study in the project's site. However, process of excavation may discover graves, especialy tombs of village patriarch.
16. Social issues
Local people may complain because they are. not satisfied with land compensation and environmental pollution, road damages. The conflict between local people and workers may happen because of different culture and religions or racism.
3.2. Operation phase
I . Noise from turbine operation.
Maximum noise level may reach to 80dBA or higher when bo.th turbine operate. It will occur about 4-5 months per year during rain season.
2. Impairment of water quality
The main enviromental impacts of the resevoir are linked to change natural flow. However, its affects are not severe like deep and large lake of big hydropower. These impacts will occur only during the first year of impoundment.
+ The water colour will increase in the first year when organic substances (humus) are released from submerged vegetation and soil.
+ Turbility will increase because of shore erosion and increased plankton production.
+ Production of phytoplankton, zooplankton during the first year together with growth of water weed may lead to contamination.
+ Near bottom, the water will be depleted disolved oxygen and production of C 0 2 will increase lead to pH drop.
+ Plankton organisms will be concentrated to the uppermost stratum
3. Reservoir sedimentation:
During the first year, the shore is not stable enough, moreover, land structure of this area consists of light compositions and soil will be easily eroded inside the reservoir. In comming years. sedimentaion will occur due to sand ancl clay deposit. Life of reservoir would shorten if road construction, mining, agriculture, and other human activities in the upper watersheds are not well controlled to reduce sediment flows into reservoirs.
4. Downstream changes including modification to naturalflows:
Hydrological regime downstream of the plant will be not changed, so that, interference in agricultural irrigation will not hapepn. However, about 0.8km May Ho Stream (after inferior dam), 1.4km of Can Ho stream (after superior dam), and 1.5km of Phin Ho stream (from confluence of above 2 streams to plant) will be effected, but not entirely dried up because of addition water from other branches and streams. Also, the calculated the flow from reservoirs will still maintain as showed on Hydraulic regime of reservoirs, which are approved by jurisdition offices. These affected downstreams have no function of agricultural irrigation, therefore, its impacts to the life of local people is eliminated.
5. Floating Aquatic Vegetation:
Production of phytoplankton, zooplankton and growth of water weed can occur during the first year. Plankton organisms will be concentrated to the uppermost stratum.
6. Impacts on fish and aquatic biota:
+ Impacts to the reservoir: as described above.
+ Downstream the plant: not much impacts in terms of aquatic life because Hydrological regime is not change.
+ The. first 2.7km after dams is impacted. However, due to of poor natural aquatic life, its impacts are not severe.
Chapter 4 : KEY MITIGATION AND MANAGEMENT MEASURES
The developer will be responsible for carrying out all mitigation measures presented in the below table. The developer's main function is construction of civil works and it has experienced staffs and full equipped machines so that the all the project's main civil works are well within its capacity. Beside, the building materials such as concrete, precast concrete, macadam ... are produced by developer. The contractor is only responsible for equipments supply and installed instruction. These measures are not only apply for this project to mitigate the negative impacts but also help to improve the Nam Tien company staffs'awareness and pratice in term of environmental protection which are applied for other hydropower plants. Furtherrn~re,~ one of them support directly to reduce the negative impacts such as sedimentary and erosive limitation for downstream hydropower plants.
