METHODS TO BE APPLIED DURING THE PREPARATION OF EMP REPORT During the study, survey and preparation of EMP report, the Consultant applied a range of following study methods: 4.1. Methods of Environmental Management Plan  Rapid assessment method The Rapid Assessment Method was issued by the World Health Organization (WHO) in 1993. Basis of this method is nature of materials, technologies and rules of natural processes as well as experiences in rating pollution load. In Vietnam, this method is introduced and applied in many social and environmental assessment study, relatively performing the accurate calculation of the pollution load in the context of limited instrumentation and analysis. In this report, the pollution load coefficients are taken under the EIA guidelines of the World Bank (Environmental Assessment Sourcebook, Volume II, Sectoral Guidelines, Environment, World Bank, Washington D.C 8/1991) and Handbook of Emission, Non-Industrial and Industrial source, Netherlands.  Impact matrix method Building correlation between effects of each project activity to each issue and environmental composition as shown in the impact matrix. On such basis, to orientate detailed contents to be studied with impacts.  Environmental modeling method This method is applied to calculate and simulate by Mathematical Equations for the process of spreading exhaust gas, wastewater generated from the project to ambient environment.  Comparison method The comparison method is to assess the environmental quality, effluent quality, pollution load, etc. On the basis of comparison with the concerning environment norms and standards, the regulations of the Ministry of Health as well as the concerning researches and related experiments in the world.  Identification method This method is applied through the following specific steps: - Describe the environment system. - Identify the project components that affect the environment. Consultant: IAC Vietnam Page 14 Updated EMP Report – The Adjustment Works under the Danang SCDP - Identify the full range of related waste streams, environmental issues to serve the detailed evaluation.  Listing method It is used quite common (since the establishment of the National Environmental Protection Agencies in some countries - NEPA) and bring positive results thank to many advantages as clear approach, systematic provision during system analysis and evaluation. It includes 2 main categories: - The description listing table: This method lists the environment components in need of research in addition to the information on the measurement, prediction and evaluation. - The simple listing table: This method lists the environment components in need of study which is possibly affected.  Systematic analysis method This method is applied fairly common in the environment analysis. The advantage of this approach is the comprehensive assessment of impacts, which is useful in identifying effects and waste sources. This method is applied based on the review of waste sources, impact sources, affected objects, environmental components, etc. like the elements in a system that has close relationship with each other, thereby, to identify, analyze and evaluate impacts. 4.2. Other methods  Public consultation method This method is applied during the interview with local officials and residents for collecting necessary information for the EIA of the Project. Namely, introducing them benefits and possible negative impacts on the environment and their lives. On this basis, make the sum of feedback about the project and expectations of local people. On the other hand, discuss and interview directly with local officials and residents on local socio-economic development situation.  The information and data inheriting, synthesizing and analyzing method The method is to identify, assess natural, economic - social conditions in the project area through the data and information collected from various sources such as Statistical Yearbook, regional social – economic reports, regional environmental status and involved research work. At the same time, it inherits available studies and reports which are really necessary because it inherits previous results, simultaneously, improve limitations.  Field survey method The field work is required to carry out the environmental impact assessment to determine the current status of land for the project implementation, concerned adjacent objects, surveys to choose sampling locations, survey the current state of water supply, drainage, power supply... The consulting agency conducted topographical, geological survey, collecting meteorological data to serve the design in accordance with the current standards of Vietnam. The survey results are used to evaluate the natural conditions of the project area. Consultant: IAC Vietnam Page 15 Updated EMP Report – The Adjustment Works under the Danang SCDP  Expert method Based on knowledge and experiences in the environmental science of the environmental impact assessment experts of the Consultant and other scientific research units.  The sampling and sample analyzing method in laboratory The sampling and analysis of samples of environmental elements (soil, water, air) is integral in identifying and assessing the current state of the baseline environmental quality in the project area. After the field survey, the sampling program and sample analysis will be set up with the main content such as sampling locations, measurement and analysis parameters, human resources, necessary equipment and tools, duration, sample preservation plan, analysis plan, etc. For this project, the project owner coordinated with the Meteorology Station in the Central region to organize monitoring, sampling and analysis of the air, water, soil, sediement and aquatic samples in the project area to assess the status of the quality of the environment components. Sampling, analyzing and storage of samples shall comply with current Vietnam standards. Consultant: IAC Vietnam Page 16 Updated EMP Report – The Adjustment Works under the Danang SCDP CHAPTER 1.

NATURAL ENVIRONMENTAL CONDITIONS 2.1.1. Geographical and Topographical Conditions Geographical Conditions Danang city is located on the edge of the Paleozoic folded domain (Truong Son orogenic zone). The geological structure in Danang area consists of 5 major stratigraphic units: A Vuong Formation, Long Dai Formation, Tan Lam Formation, Ngu Hanh Son Formation and Quaternary Sediment, in which the lithological composition of A Vuong Formation, Long Dai Formation, Tan Lam is mainly shale and sandstone. Ngu Hanh Son Formation is mainly gray, white and flowering limestone. The quaternary sedimentary includes the formations of rivers, river - sea, sea, sea - swamp from early Pleistocene age to late Holocene age. The lithological composition is mainly sand, pebbles, gravel, sand, clay, etc. The earth case in the territory of Danang City contains many latitude and meridian fault systems that separate, reduce the continuity of rock, their strength, especially create fractured zones and water containing level. Topographical Conditions The high and steep mountains concentrate in the west and northwest, forming the mountain ranges that reach out to the sea. It is home of many watershed forests which are meaningful for the protection of the ecological environment of the City. The coastal plain is low-lying area which is under the influence of the ocean salinity, where there are establishments of agriculture, industries, services, military, residential and functional areas of the City. The entire project works are distributed in flat areas of the coastal plain. Figure 2-1: Terrain of Danang city Consultant: IAC Vietnam Updated EMP Report – The Adjustment Works under the Danang SCDP 2.1.2. Climate conditions According to statistics of the Central region meteorological station, Danang has a typically tropical monsoon climate with high temperatures and slight volatile. Danang has two separate seasons with rainy season lasting from August to December and dry season between January and July. Cold winter occasionally occurs but does not last long.  Temperature: The average annual temperature in Danang is some 25.9ºC with the highest temperature ranging from 28ºC to 30°C in June, July and August and the lowest between December and February, varying from 18 to 23°C.

In the city center, the frequency of calm wind is quite high (30-50%). The average wind speed in 2009 was slightly low (1.4 m/s) and not too different with the previous years. The average wind speed varies from 2.3 to 2.7m/s. The annual average Consultant: IAC Vietnam Updated EMP Report – The Adjustment Works under the Danang SCDP number of hurricanes is 0.84. Nevertheless, no storm has been recorded in some years while in other years there are from 3 to 4 hurricanes. Storms frequently occur from May to August. The highest average wind speed of storms and tropical depression ranges from 15 to 20 m/s (level 7-8). 2.1.3. Hydrological and Oceanographic characteristics River network Da Nang’s river network mainly derived from the West and Northwest of the city and Quang Nam province. Most rivers in Danang are short and steep. However, this is the main fresh water supply source for Danang City. The river system crossing the city has many tributaries including the Tuy Loan River, the Cu De River (in the north), the Yen River, the Qua Giang River, the La Tho River, the Vinh Dien River and the Han River. The Tuy Loan River and Cu De River have separate catchments located within Danang City. - Vinh Dien river: Vinh Dien river is a branch of Thu Bon river with the start point at Cau Lau bridge and about 5km towards the upstream. Vinh Dien river carries a part of water in Thu Bon river and receive additional flow from La Tho and Qua Giang rivers before pouring into Han river. - Cu De river: Cu De river basin is located in north of the city and shaped as bird’s feather, inclined towards the Northeast - Southwest . The total area of the river basin is 472km2. The total length of Cu De is 38km. The downstream of Cu De river is often salinizated in the dry season. In flood season, stormwater from the Southwestern basin bounded by An Ngai and So mountains with area of 6,6km2 flows in combination with water level rise of Cu De river will cause widespread flooding. The submerged depth depends on the extent of annual flooding. The highest water level is from 2m (1999). - Tuy Loan river: Tuy Loan riber basin is located on the left of Vu Gia river and connects with Cu De river basin. Tuy Loan river originates from Ba Na mountain at altitude of 1,487 m with a length of about 30km. The catchment area from the river mouth to the junction of the Tuy Loan river with Yen river is 280km2, the average slope of 15%, average basin width of 25km, the average basin width of 10.3km. Tuy Loan river connects with Yen river to form Cau Do – Cam Le river and poured into Han River. - Han river: Han river is the ending point of Vinh Dien river, Cau Do – Cam Le river and pours into Danang sea. The current regime of Han river is strongly influenced by the tide of Danang sea. - Phu Loc river: Phu Loc river is one of the main drainage channels of the city. This river originates from the point connecting with the West Lake and flow through Danang bay crossing the estuary on Nguyen Tat Thanh road, Thanh Khe Dong ward. - Co Co river: Formerly, Co Co river was a coastal river connecting with Thu Bon river at the section of Cua Dai. Currently, this river is sedimented and becomes a dead-end river with the river flow during the dry season in Danang mostly from Cai river and Han river flowing back in. - Yen and Qua Giang rivers: These rivers are beloning to Vu Gia river system, therefore, the hydrological regime of such two rivers is closely correlated together. These rivers mainly flow through the plains, dense canals and ditches. The difference in elevation between the river bed and the surrounding area is minor. In flood season, the water level rises rapidly and causes widespread flooding. However, water is often drawn Consultant: IAC Vietnam Updated EMP Report – The Adjustment Works under the Danang SCDP very rapidly in the later few days. Yen and Qua Giang rivers have small flow velocity (V1% = 3.3m3/s) with good water quality for serving irrigation for adjacent fields. - Tay Tinh river: Tay Tinh river has a narrow bed width and small flow velocity (V5% = 1.34m3/s). This river only serves as an irrigation channel for adjacent fields. Figure 2-2: River Network in Danang city Tidal regime Tidal regime of Danang sea consists of diurnal tide and irregular half-diurnal tide which means that in half a day, there is one flow and one ebb but the power of and the time the flow and ebb last are much different. There are in average 03 days of diurnal tide per month (8 days at maximum and 1 day at minimum). Affected by such a tide regime, the hydraulic regime of the canals and sewers in the City is relatively complicated. During floods, the sewers and canals receive both storm water and wastewater from residential areas. Moreover, they are also affected by raising water and wave during flood tide. The highest average flood tide level is 120cm and the lowest one is 80cm. 2.1.4. Climate change and sea level rise In 2011, the Ministry of Natural Resources and Environment has released the report on "Scenarios of Climate Change and Sea Level Rise for Vietnam" which represents maps of rising levels of temperature, rainfall and flooding risks for some areas in Vietnam. Danang is one of the coastal cities that is likely to be severely affected by sea level rise. Therefore, the planning of areas at risk of inundation can also be considered as an important direction for the development track of the City. Consultant: IAC Vietnam Updated EMP Report – The Adjustment Works under the Danang SCDP Figure 2-3: Map of inundation areas in Dang city corresponding to sea level rise by 1m (Source: Scenarios of climate change and sea level rise for Vietnam, MONRE, 2012) The map indicates that when sea level rises by 1 meter, the areas most prone to inundation are on the right bank of the Cu De River (mainly in Hoa Lien commune and Hoa Vang district) and on the eastern bank of the Han River, where the Cam Le and Do Toa River merge (mostly in Cam Le and Ngu Hanh Son districts). 2.1.5. Current Status of Quality Environmental Compositions To assess the quality status of the environmental components in the project area, in June 2015 and December 2015, the Consultancy firm in collaboration with the Meteorological Observatory Central implemented the survey, monitoring, measuring and sampling the environment under the Vietnamese standards and the analysis in laboratory. Simultaneously they collected information and relevant data. The detailed results of each sample analysis are in the Annexes. The methods of measurement and sampling at site, maintenance, transportation, treatment and analysis of samples in laboratory are implemented in accordance with current Vietnam’s standards. 2.1.5.1.

In brief, residential wastewater in mornitoring locations has exceeded permitted standard of wastewater before releasing into environment. Residential wastewater in Da Nang city contains organic substances (BOD), sediment, Amoni, N sum, P sum, smell and zymoma. Such wastewater is not fully treated being discharged into the city’s drainage system/ Thus, construction investment, improvement waste water collection and treatment system at these areas is necessary. According to survey repor of Saigon weico conducted with Hoa Xuan wastewater treatment station, input and output wastewater of station is checked and analyzed from 1/6/2016 to 31/08/2015. The results are presented as follow: - The input parameters of Hoa Xuan wastewater treatment station exceeding standard many times (compare with Standard of Vietnam 14: 2008 / BTNMT and Standard of Vietnam 40: 2011 / BTNMT) except pH, nitrate, total nitrogen and total phosphorus are not exceeded. It is caused by input wastewater of Hoa Xuan stations are urban wastewater, including domestic waste water and waste water from industrial zones and villages (mostly untreated) mixed together, resulting in the criterias exceeding the permitted standards. - The output parameters of Hoa Xuan station are both within the permitted standards.

Of which Euglenophyta accounts for a highest portion, 42.2% with 8 species. Dinophyta, Cyanobacteria and Bacillariophyta account for 21% and Streptophyta accounts for 5.3%. The composition and distribution of seaweed is plentiful and varied. However, there are some significant impacts to this area related to the low primitiveness which is reflected through a higher portion of Chlorophyta than Bacillariophyta. For Zooplankton compositions, 09 species of 3 main branches including Arthropoda, Cladocera and Copepoda have been collected at the lake bed. Of which, Arthropoda with 6 species accounts for 66.7%, Cladocera with 2 species accounts for 22.3% and Copepoda with one specie accounts for 11.1%. Although the phytoplankton compositions are quite plentiful, the zooplankton compositions are less plentiful and varied. This is caused by activities in this area divide lakes, which restrict habitat of Zooplankton. The analytical results of Zoobenthos show that there are mainly species of Mollusca and Annelida. Of which, Mollusca with 3 families accounts for 75% and Annelida with one specie accounts for 25%. Although the aquatic analytical results at Hoa Khuong pond showed the diversity higher than urban lakes, there are still negative impacts on environment quality at lakes.

And: - Ong Ich Khiem pump station has the coordinate of 1604’50.4’’-108012’39.59’’which is not under the management of coral reef preservation and ecosystem of the sea from Hon Chao to Nam Hai Van and Son Tra peninsula (according to Decision No. 54/2007/QD- UBND dated 13/9/2007 by Da Nang People’s Committee on promulgating the management, preservation of coral reef and ecosystem). - According to map of aquatic vegetation of Da Nang Bay, the coastal area of Ong Ich Khiem outlet is mostly free from coral and seaweed. - Otherwise, as mentioned in Project Description, pump station is activated only when flood tide and lasting, heavy rain. Partition gate will be closed to prevent water spilling from the Bay to sewerage system, then the station will operate to release water. The station will not be activiated in normal conditions, and water flows freely in sewers when no flood tide or sea rise in Da Nang Bay. Therefore, the impact of the pump station is insignificant. Hence, it can be concluded that during operation process, Ong Ich Khiem anti-flood pump station creates no impacts to biological diversity 2.1.6. Ecology Danang city is characterized by a diversity of terrain, is the crossroad of climate sub-areas, which has led to a diversity of ecosystem. Specifically, Danang is at the intersection of two large biodiversity centers called Bach Ma and Ngoc Linh; thus, the fauna and flora in Danang are rich in species (WWF, 2004). In addition, Danang has diversity in culture as well as agricultural production types; hence, the agricultural ecosystems here are also possessing a high biological diversity. Consultant: IAC Vietnam Page 74 Updated EMP Report – The Adjustment Works under the Danang SCDP Forests and vegetation: the forests in Danang city are mainly concentrated in the western Hoa Vang district, a few in the districts of Lien Chieu, Son Tra, Ngu Hanh Son. Coverage rate was 33.1% in 2009, timber volume was about 3 million m3, distributed mainly in steep areas with complex terrain. The natural forest areas are Ba Na - Nui Chua area, Son Tra peninsula, south Hai Van. SON TRA SOUTH HAI VAN PENINSULA AREA PROJECT AREA BA NA – NUI CHUA NATURE RESERVE Figure 2-4: Vegetation map of Danang city  Natural Reservation Area: Ba Na - Nui Chua Nature Reserve: with a total natural area of 28,030 ha, of which the area of forests and forestry land is 26,992 ha, the area of non-forestry land is 1,037.2 ha. There are 793 species of plants, 487 genera and 134 families of 4 branches. Rare plants put in the International Union for Conservation of Nature (IUCN) red list include: Aquilaria crassna pierre, Madhuca pasquieri, Dalbergia cochonchinensis, Sindora tonkinensis. Son Tra peninsula: Son Tra nature reserve has a total natural area of 2,591 ha, of which the area of forests and forestry land is 2,512.1 ha. The plants in Son Tra nature reserve are relatively diverse with 985 species including 22 rare species recorded in Vietnam's Red Book. South Hai Van area: a total natural area of 2,544.2 ha, of which the area of forests and forestry land is 2,091.5 ha. The special use forests of the south Hai Van area are adjacent to Bach Ma National Park (Thua Thien - Hue province) and Ba Na - Nui Chua zone, forming a corridor large enough to conserve and grow endangered species. In terms of environment, Hai Van creates distinct differences in climate and weather between two mountain slopes – the southern slope (Danang) and northern slope (Thua Thien - Hue), protecting Danang city from direct impact of annual hurricane as well as regulating salinity level for Cu De river. The natural coastal forests here are well protected, the vegetation is dominated by species such as Symplocos longifolia and Lithocarpus nebulorum (ADB, 1999). However, most of the Consultant: IAC Vietnam Page 75 Updated EMP Report – The Adjustment Works under the Danang SCDP mountain pass area are planted forests with common Acacia auriculiformis, A. Mangium and Pinus sp.  The other ecological sites: Outlet of My Khe and My An, Ngu Hanh Son district: This is the tourism beach and is the location of anchoring of some small boats of fishermen, long and clean sand beach with good water quality, unremarkable coastal ecosystem. The coastal typical species including 191 species of hard coral reef and 3 species of soft corals, 72 species of seaweed, 3 species of seagrass bed, 162 species of coral reef, benthos and phytoplankton. Bau Tram lake: Bau Tram lake has the largest water surface area among all lakes in Danang city (about 60ha). The flora around the lake is mostly shrubs. Land bordering the lake at some points is cultivated by the people. According to the monitoring results, lake water has signal of lightly polluted. According to the map location of works Figure 1-2 and Figure 2-4. Due to adjustment and supplementary work items,mainly concentrated in urban areas, small construction activities, unfocused and away from nature reserves area: - Location of the area near Son Tra Peninsula is Tho Quang – Bien Dong and wastewater collection pipelines of Pham Van Xảo road, Tho Quang industrial fisheries zone- which is far from 3km The Son Tra Peninsula area to the northeast. - Location near Ba Na – Chua Mountain Reserve is where of Depot terminal station in Bau Tram – 4 km away from Ba Na – Chua Mountain Reserve to the SouthEast. - The remaining works are far from nature reserve area more 5km. - Thus, impact of the construction of the adjusting items, additional projects to the nature reserve is negligible even no impact 2.2. SOCIO-ECONOMIC AND INFRASTRUCTURE DEVELOPMENT STATUS 2.2.1. Socio-economic Situation The adjustment and supplementary works under the Danang SCDP are scattered in entire city in which Hai Chau, Thanh Khe and Lien Chieu are concentrated with most works.

With the establishment of the University of Medicine and Pharmacy and the Medical Technical University in the city, Danang is orientating to become a major medical center of the Central - Highland region and the whole country, providing high quality human resources and health services for the socio- economic development of the country. Consultant: IAC Vietnam Page 77 Updated EMP Report – The Adjustment Works under the Danang SCDP  Some socio-economic information of the project area: According to the results of survey carried out in June 2015 for households living at the project area, some basic information is as follows: - At the project area, there is no ethnic minority living. Average household size is about 3.7 persons/household, including 49.3% of male and 50.7% of female. - Most of household heads have education level from secondary or higher, of which the portion of upper secondary education level is highest (52%), followed by intermediate, college and university (30%). The number of persons with secondary education level or lower accounts for a lowest portion (18%). None case of illiterate is found. - Income level of households is mainly from income group over 70 million dong/household/year (accounting for 63%). Average monthly income per household member is about 1.4 million dong or more. - The results of survey for 550 households show that among affected households, those engaged farming account for highest portion (more than 50%). It is followed by the portion of households earning wage (about 30%) and small business households (approximate 17%). The rate of unemployment of laborers in working age is minor (below 1%), concentrated in group of teenagers who have not been vocational trained. - The number of farming households are mainly concentrated in Hoa Nhon and Hoa Son communes. The people are still allocated to cultivate however agriculture is no longer primary income source. The number of households with members earning wage are distributed homogeneously in the surveyed localities. Some occupations include public servants, workers at private enterprises in the industrial park as well as business and services. Business households are mainly private entities either trading at home or renting business premises at the markets or tourism area. - According to the survey results, the households’ facilities are quite sufficient and modern. Some popular facilities include color televisions, motorbikes, phones, refrigerators. The portion of households owning air-conditioners and washing machines is very high. - Most of houses owned by surveyed households are permanent (with one or two floors), accounting for 75.6%. It is followed by the semi-permanent houses (brick wall, tile/iron roof – house grade 4) accounting for 24.4%. 2.2.2. Status of traffic Danang is located in the middle of Vietnam on the North-South arterial road axis of the highway- railway-seaway-airway. Danang city is also the ending point of the East-West economic corridor crossing Myanmar, Laos, Thailand and Vietnam. In the framework of the study scope of the project, a number of and roads related and directly affected from the implementation process of the project include: Provincial roads: - Nguyen Luong Bang road (National highway 1A) is a national highway intersecting with the starting point of the existing Nguyen Tat Thanh road (joining with the Northern ring road) and the Southern ring road under the Project. - Hai Van – Tuy Loan bypass, intersecting the ending point of the Northern ring road; - Existing Nguyen Tat Thanh road runs along the beach and connects with the Northern ring road; Consultant: IAC Vietnam Page 78 Updated EMP Report – The Adjustment Works under the Danang SCDP - The road is invested fully with the lighting, drainage systems and asphalt pavement. The traffic density on the road is quite high, especially in peak hour. - The provincial road DT605, the section intersecting with the railway and the Southern ring road; - The National Highway 14B, the section intersecting with the Southern ring road; These roads are quite wide with asphalt pavements and mostly equipped with the lighting systems and drainage sewers. The traffic density on these roads is quite high, especially at the National Highway 1A where heavy trucks are regularly operating. These arterial roads are also service ones which serves the transport of materials, excavated soil from the construction site in entire project area. Figure 2-5: Traffic orientation map of Danang city towards 2020 Urban roads: - Peri-urban area (located in Hoa Vang district): The remaining roads in the project area are mainly inter-village ones. These roads are often aggregated, concreted or some earth road sections, therefore, the quality is unguaranteed, which makes difficult for means of transports to travel. - The central area (in Lien Chieu, Thanh Khe, Ngu Hanh Son districts): This is an urban road completed with full infrastructure such as water supply, drainage, lighting and cable, etc. The quality of road is very good (because this is asphalt and asphalt concrete road) and regularly maintained. The traffic density is medium - Nguyen Tat Thanh extension road built will contribute to promoting the development of the Northwest urban areas of the city. The road will connect the tourism centers of the Consultant: IAC Vietnam Page 79 Updated EMP Report – The Adjustment Works under the Danang SCDP city, including Son Tra Peninsula, Thuan Phuoc bridge and Nguyen Tat Thanh coastal tourism road with the Thuy Tu urban area. - The proposed Hoa Phuoc – Hoa Khuong road (is invested to build in SCDP Project) is the southern ring road of the city, in the middle of the National Highway 1A to the East and axis of the National Highway 14B to the West. The proposed road will provide East-West connectivity and reduce traffic congestion. In the East, the road will connect with the National Highway 1A at Son Tra – Dien Ngoc road (the road connecting with the Univeristy Village). In the West, the road will connect with the planned provincial road 604 (Hoa Phu). - The two proposed roads will contribute to innovating the urban and distribution of population through encouraging people to live in the new urban areas of the city, reducing the population density in the central/southern areas as well as minimizing traffic flow of the crowded roads, attracting foreign investment and promoting economic growth of Danang city. 2.2.3. Water supply According to Statistics data of 2013, Da Nang Water Supply Company is operating 03 water supply facilities with a total design capacity is 155.000m3 / day; Current capacity is 130.000- 140.000m3 / day. Cau Do water supply plant is one of the three largest plans with a capacity of 120.000m3 / day; Airport water treatment plant with medium average, with a capacity of 30,000m3 average / day, and Son Tra water supply plant with a capacity of 5,000m3 / day. On water pipe network, pipeline type I of company has length of 287 kilometers (Ø> 200); pipeline type II is 253km long (Ø 100-200); and III pipeline type III is over 3,000 kilometers long. The total includes 120,000 connected equipment electronic clock. The proportion of people are providing clean water in 06 urban districts over 65%, including approximately 130,000 households with 500,000 people. On average, water consumption is 128 liters cities / person / day.

Consultant: IAC Vietnam Page 80 Updated EMP Report – The Adjustment Works under the Danang SCDP  Water Supply Orientation Phase 2 (towards 2020): Nearly 10 years ago, the city was determined to build a sized and modern Danang water supply system, therefore, currently, Water Supply Company has completed and City Water Supply Project Phase I (120,000 m3 / day night) has been exploiting. From 2015 to 2020 the city water supply project phase II will have been completed, improving the ability to supply water to 325,000m3 / day night as follows: Pipeline network of Danang city has currently focused on the area of Hai Chau, Thanh Khe, Son Tra. At these areas, the covered rate is 90% of the residential area. At Lien Chieu, Ngu Hanh Son districts, the main pipeline network level I was built, network of level II and level III has been growing. In the area of Hoa Vang district, water supply network is not almost found, only some coatal communes have pipelines of level II and level III. The proportion of people using clean water supplied by the Water Supply Company is 9.5%. Also, planning of Phase 2 will concentrate for the development of pipeline networks in suburban areas, the pipeline for Hoa Vang District, pipeline grade II and grade III for Ngu Hanh Son and Lien Chieu districts. 2.2.4. Drainage Status 2.2.4.1. Surface water drainage According to Statistics data of 2013, stormwater drainage system consists of about 270 km of box culverts, construction ditch and about 20km of land ditch. Stormwater drainage network is a combined system of storm water and waste water which are mainly located in the stone – paving road( stone/ concrete). The typical storm drainage sewers have width of 800 mm and height of 1200mm. Following drainage plan of Da Nang city towards 2030, the city has implemented many projects by investment capital sources from abroad and within the country to renovate and expand the drainage system for stormwater and wastewater, however, construction has not been completed, many areas are still flooded. Review the current situation of drainage capacity of the system as follows: - For the northern region: Due to the complex terrain, when storm water from Phuoc Tuong mountain flows down at a faster rate causing flooding at downstream. Drainage capability is increasingly reduced because the system is not regularly maintained and are being occupied by the civil works. - For the center region: Districts of Hai Chau and Thanh Khe, some positions are often flooded and prolonged due to the lack of sewers and small drainage sewers but meet the demand of drainage for the large basins. Capacity of drainage is good in other areas. - For the Eastern region: The sewers are large, building density is low, the terrain is relatively high, storm water drainage capacity is quite good, less frequent flooded. Consultant: IAC Vietnam Page 81 Updated EMP Report – The Adjustment Works under the Danang SCDP Figure 2.1: Current stormwater drainge system Figure 2-6: Location map of area frequently flooded 2.2.4.2. Waste water collection and treatment According to drainage plan of Da Nang city towards 2030 (November 2015), its existing wastewater drainage system is mostly the common drainage system. The city's waste water is collected by coastal sewers, sewers near rivers and lakes, lakeside wells through Combined Consultant: IAC Vietnam Page 82 Updated EMP Report – The Adjustment Works under the Danang SCDP Sewer Overflow (CSO) at the outlets. Only one small part of the planning area with separate collection systems for waste water treatment plant. Most households have septic tanks. For household septic tanks, the rate of connecting directly to the drainage system level 3 is not high (approximately 15-20%), mostly households use from septic tank majority to the ground. For domestic water from kitchen, washing, about 46% of households connecting to the collection and drainage system into waste water treatment station. In Da Nang city, there are 5 centralized industrial parks: Hoa Khanh, Lien Chieu, Tho Quang Fisheries Service, Da Nang and Hoa Cam. These industrial zones have separate wastewater collecting and treatment system. After treatment, waste water needs to be within permitted standard before discharging into receiving water source. Diagram of existing waste water treatment stations of Da Nang city is shown in the figure below: Figure 2-7: Existing waste water treatment stations of Da Nang city Currently, it is estimated that there are only from 15% to 20% of households which are connected to the drainage system. Wastewater is collected into separate sewer system and moved to be treated at 04 existing waste water treatment plants: Hoa Xuan (capacity of 20,000m3 / day), Phu Loc (capacity of 40,000m3 / day), Ngu Hanh Son (capacity of 10,000m3 / day), Hoa Cuong (capacity of 40,000m3 / day) and Son Tra (capacity of 10,000m3 / day) through one sewer system and pressure booster station. In addition, there are also 5 waste water treatment stations of the industrial zones in the city, including: Waste water treatment stations of the industrial zones of Lien Chieu, Hoa Khanh, Danang Seafood service, Hoa Cam and Da nang. Consultant: IAC Vietnam Page 83 Updated EMP Report – The Adjustment Works under the Danang SCDP 2.2.5. Status of solid waste collection 2.2.5.1. Domestic waste According to Statistics data of domestic waste collection and treatment by the Urban Environment Company (URENCO), Danang waste about 630 tons of domestic solid waste every day, approximately 85% of which are collected by companies. URENCO conducts daily garbage collection in the urban districts. In the districts of Danang city, the centralized waste diposal site is used to collect garbage from people. Then, waste is transported to be treated in the solid waste treatment site in Khanh Son landfill. Solid waste treatment site in Khanh Son landfill has a total area of about 10 hectares, consists of 3 seperating lines of garbage manually associated with machines with a total capacity of 800 tons of waste / day; 2 production lines PO, RO from plastic waste with a total capacity of 63 tons of nylon / day; 1 production line of adobe bricks with capacity of 65 tons/day and 1 waste furnace with capacity 162.6 tons / day together with a heat recovery system to produce industrial pellets from organic solid waste. On 27th June, 2015, Vietnam Environment JSC inaugurated the first phase of the project with a capacity of processing 200 tons of waste / day. The phase 2 of the project is estimated to be completed by the end of 2016. Thus, through the disposal of waste towards recycling and solid waste treatment site in Khanh Son landfill not only contributes to reducing the amount of burial waste but also allows taking advantages of the waste components to form the energy and useful products. Consultant: IAC Vietnam Page 84 Updated EMP Report – The Adjustment Works under the Danang SCDP Discharge about 630 tons/ Households garbage/day Types of garbages have value (paper, plastic, metal) are collected by company Bucket Located in city corners (4500) 85% of arising garbage is collected Collected by specialized vehicles Transit stations Transported by trucks Khanh Son centralized landfill Vehicles preventing station Landfill Garbage can be recycled Sanitary landfill Figure 2-8: Solid waste management system in Da Nang city 2.2.5.2. Sewage sludge The city's sewage sludge has 2 main sources including: sludge dredged from the sewer system and septic tank sludge. This sludge is collected by drainage company and transferred to Khanh Son landfill (receiving capacity of the landfill is 650 tons/day) under the management of Da Nang Urban Environment Joint Stock Company.

ANALYSIS OTHER ALTERNATIVES ON TECHNIQUE Besides the analysis and evaluation alternatives of WITH and WITHOUT ADJUSTMENT, SUPPLEMENTARY project with 3 components, there are some works in the process of research, design consulting unit has launched various technical alternatives. This section will analyze the alternatives based on the key elements: technical, economic and environmental – social issues. Consultant: IAC Vietnam Page 88 Updated EMP Report – The Adjustment Works under the Danang SCDP 3.2.1. Interchange of Dien Bien Phu, Nguyen Tri Phuong on BRT system ( Dien Bien Phu tunnel work)  Status Interchange operates at rush hour in the morning, and in the afternoon. Circulation speed remains low interchange with many traffic conflicts. Traffic congestion occurs at rush hour for all branches. Especially there are conflicts between line going straight to interchange on Dien Bien Phu road with lines going straight or turning left on Nguyen Tri Phuong and Le Do roads.

ENVIRONMENTAL IMPACT ASSESSMENT 4.1. IDENTIFICATION OF POTENTIAL IMPACTS Implementation adjustment and supplementary items will increase effectiveness of SCDP project, create positive impacs on living conditions, environmental conditions and infrastructure services in the project area. The main positive effects of the project are as follows: - Wastewater collection and treatment systems: Increased ability to collect and treat water will contribute to improvement of environmental sanitation condition in order to ensure the health of people, gradually complete drainage planned targets of Danang city by 2030 and vision 2050. - Drainage and flooding solution: The project involves in improving drainage sewers systems, canals and lakes in urban and residential areas. Additional, adjustment items will contribute to improving the existing water drainage system, improving existing drainage infrastructure in residential areas, minimizing impacts of flooding in the case of getting adverse weather. - Environmental Landscape Improvement: The project will enhance the aesthetics and value of tourism to the city, and it might create positive changes for microclimate conditions in the region. Two stormwater outlets of My An and My Khe which is currently located at the main beach area, will be renovated and planted trees surrounding. Hoa Phu Lake can be used as public parks and recreation center after being upgraded and renovated and investment in wastewater collection system. Stormwater and wastewater seperation systems have been gradually improved; contribute to surface water environmental protection (rivers, lakes and coastal water). - Reducing the risk of traffic congestion, reducing greenhouse gas emissions: According statistics in 2012, system (pilot) horizontal BRT of city when coming into operation, will attract major traffic amount. The change from personal vehicles (cars and motorcycles) to public transport will contribute to reducing significantly transport emissions and traffic accidents. Also, addition of items for underpass of Dien Bien Phu contributes to reducing traffic congestion at rush hours, reducing fuel consumption. - Urban expansion and development of suburban areas: Construction strategic roads (ring road to the North and the South) will connect the overall transport of the city, as the basis for the urban development. Also, the additional building of technical infrastructure for Hoa Khuong resettlement site contributes to gradually improving living conditions in suburban areas, reducing population pressures in urban areas. 4.2. POTENTIAL NEGATIVE INPACTS This section summarizes the potential impacts of the project, basing on the characteristics of the project and the collected environmental database, using the experience in implementing similar projects in our country and the foreign ones and in accordance with the procedures and report forms on environmental impact assessment processes of Vietnam government and the environmental safeguard policies of World Bank. 4.2.1. Type and Scale of Potential Negative Impacts In general, the operational phases of the project cause different impacts on the environment. The sources of environmental impact on the project are identified in 3 phases: Consultant: IAC Vietnam Page 96 Updated EMP Report – The Adjustment Works under the Danang SCDP - Phase I - Preparation for construction: Making reports on project investment, design, compensation and site clearance, bomb clearance and so forth. - Phase II - Construction: Leveling, construction of work items, technical work and installation of equipment and so forth. - Phase III - Putting the project into operation. This report is used impact matrixes for screening the effects separately by category (physical, biological, social, etc.) and each type of project. These impacts will be determined the specified extent as follows: - No (N) – No impact; - Low (L)- Small works, impact at a low level, on a local scale, temporary effects and self-recovery capabilities - Medium (M)- Small works in urban areas/ sensitive areas, at the medium scale with moderate impacts which can be reserved and take place on a local scale in the temporary period time. - High (H)- Scale works in urban/ sensitive areas, impact at the high level with significant impacts on the society and/or the environment, in which some cannot be reversed and require compensation/reimbursement In general, all operations of adjustment and supplementary items, supplements are concerned construction works with small and medium scale, in which most of the negative environmental impacts that can be changeable, temporary, local and be mitigated through application of construction management measures and appropriate technology, and monitoring of implementation process of contractors and public consultation of local community. However, type and nature of impact changes significantly according to nature and scale of operation, location, and environmental conditions and society, human habits and factors of time.

Impacts on Tombs and Other Cutural Works According to results of RP report for adjustment works of SCDP project, 04 tombs are scattered in affected areas which have to be relocated. Accoring to the results of consultations with households and local authorities, they agreed to relocate tombs as well as fence and yard of the ancestor temple. Thorugh consultation at local, all local people and authorities supported the project and willing to relocate tombs to appropriate places if they receive adequate assistances. b. Impacts by bomb clearance Bombs, mines and explosives left after the wars shall be carefully cleared in service of the site clearance to build the road and ensure the safety of the works. Consultant: IAC Vietnam Page 104 Updated EMP Report – The Adjustment Works under the Danang SCDP Most of works of adjusted and supplemented items are built on available roadbase: Improvement of storm and waste water drainage system, lakes, infrastructure construction for residential site..., thus,bombs, mines and explosives clearance are not necessary. Therefore, it is required to pay attention to bombs, mines and explosives clearance, including: - Construction anti-flood station at the end of Ong Ich Khiem road - Adjustment of capacity for Lien Chieu waste water treatment station - Construction BRT Deport at airport area( adjacent crossroad of Nguyen Tri Phuong road and Nguyen Van Linh road) - Technical infrastructure construction of group 5,6,7 of Son Thuy commune. - Dien Bien Phu underpass (Interchange Dien Bien Phu, Nguyen Tri Phuong, Le Do) - Construction infrastructure for Hoa Phong resettlement site This work will be carried out by specialized units of the Army. The process of bomb and mine clearance is usually dangerous to humans and animals accessing the areas in progress of clearance. Therefore, the project owner and the responsible unit shall use protective barriers and warning signs to minimize the possible risks and dangers to people and livestock 4.2.3. Impact assessment during the contruction phase 4.2.3.1. General impacts of Project During the construction process, impacts mainly arise as dust, emissions, noise, solid waste, domestic waste water from workers and households. Due to small-scale construction, these impacts are only at low level and can be mitigated by management measures. a. Air pollution Degree of dust dispersion form excavation, ground leveling: Level of dust generation during the process of leveling depends on volume of excavation, embankment and aggrandisement. Volume of diffused dust is calculated basing on pollution coefficient and volume of excavation and leveling. According to the instruction documents of the World Bank regarding environmental impact assessment (Environmental Assessment Sourcebook, Volume II, Sectorial Guidelines, Environment, World Bank, Washington D.C 8/1991), the pollution coefficient E is calculated by the following formula: 1,4  u    E  k  0,0016   2,2  1,3 M     2  (1) In which: - E - Pollution coefficient (kg/ton). - k - Grain structure with average value of 0.35. - Average wind speed in the project area (2.3 m/s). - M - Average humidity of materials (20%). With the conditions of average grain structure, average wind speed, humidity of leveling materials and so forth, we can calculate the pollution coefficient E = 0,01189 (kg/ton).

The result of dust dispersion concentration in the table above shows that total concentration of dust every 1h at earthwork locations for supplementary, adjustment works has exceed the standard QCVN 05:2013/BTNMT (limit: 0.3mg/m3) at items of works 1.1 and 3.1. - The concentration of dust has exceed the limit of standard QCVN for item 3.1- Component 3 ( Construction Hoa Khuong resettlement site), exceeding 4 times than standard of Vietnam due to large volume of excavated soil and backfilling land. Consultant: IAC Vietnam Page 106 Updated EMP Report – The Adjustment Works under the Danang SCDP - In addition, dust concentration has exceeded the permitted limit for group of items 1.1 under component 1, exceeding 2 times than permitted limit. Concentration mainly focuses on construction anti-flood pump station at the end of Ong Ich Khiem. - For groups of other works, total concentration of dust is basically lower than the permitted limit of QCVN 05:2013/BTNMT. In fact, concentration of dust generated is not higher than calculation due to location of works scattered in the area of the city. Also, the construction time of each work items is different. Moreover, concentration of dust generated decreases very fast by the distance to the source and mitigation measures will be mentioned in Chapter 4, namely, impacts of dust on surrounding air environment as well as local people living near the project area. In general, the concentration of dust generated from excavated, backfilling activities can affect to the air. However, as construction works are often carried out in different stages and not concentrated in one place but scattered on the project site, the actual concentration level will be lower. Dust is highly concentrated in the construction area and the objects directly affected are the workers at the site and residents living near the ground leveling locations. The dust is only generated during construction and will disappear upon the construction is complete. Air pollution caused by dust will reduce upon the application of preventive measures such as spraying water onto the road; thus, the dust pollution caused by transport activities on road is rated at average level. In addition, during the construction, the Investor will require the construction contractors adopt appropriate measures to minimize dust generation. Pollution by dust and gases generated from transport vehicles According to volumes of earthwork of components excess excavated soil will be transported to another location or to the landfill; volumes of lacking excavated soil will be transported from raw material exploitation area.

With an average working frequency of 8 hrs/day, average distance of 32 km/day (2 turns/day x 2 turns x 8 km/turn). Hence, the number of turns is shown in the following table (average loading capacity of a vehicle is 8 tons/vehicle). Every 2 non-loaded vehicles is presumed as 1 loaded vehicle. Hence, the total number of turns for carrying the ground leveling soil is shown in the following table: Table 4-10: Number of turns for transporting excavated soil No of vehicles No of turns used to No Name of work item turns transport Group of works for storm water drainage 1.1 10,084 15,127 system improvement– Component 1 Group of works for flood treatment at 1.2 1,430 2,145 residential sites– Component 1 Group of works for waste water collection 1.3 270 405 system construction- Component 1 Group of works for waste water treatment 1.4 3,534 5,302 stations – Component 1 2.1 Group of works under Component 2 355 533 3.1 Group of works under Component 3 64,675 97,013 Note: (1.1) – Group of works for storm water drainage system improvement, component 1; (1.2) Group of work for flood treatment at residential sites, component 1; (1.3) Group of works for waste water collection system construction, component 1; (1.4) Group of works for waste water treatment station, component 1; (2.1) Group of works under component 2; (3.1) Group of works under component 3. In the process of construction, it is essential to use many vehicles, equipments involved in the process of transporting materials and construction… Diesel is main fuel consumption, operation of these vehicles and equipments will generate waste into environment, including: hydrocacbon, COx, NOx, SO2, dust from transport vehicles. Load of emission depends on elements such as type of engine, engine capacity, type of fuel used, operation of air, distance of transporting… Level of emission depends on elements, namely: road quality, density, lanes, technical quality of vehicles and amount of fuel used… According to rapid pollution assessment coefficient of WHO, 1993, load of emission of waste from vehicles using diesel as follow: Table 4-11: Components of motorized vehicles emission Type of fuel Components of emission Petrol (g/kg) Diezen Oil (g/kg) Consultant: IAC Vietnam Page 108 Updated EMP Report – The Adjustment Works under the Danang SCDP Oxit cacbon (COx) 465.59 20.81 Hydrocacbon (CxHy) 2328.00 4.16 NOx 15.83 18.01 SO2 1.87 7.80 Dust 1.00 5.00 (Source: Assessment of sources of air, water, and land pollution, WHO, 1993) It is supposed that total diesel-driven vehicles with consumption level is 14kg/100km.

Results of predicted load calculated for maximum dust and exhaust gas pollution of each vehicle is described in the table above. With the average working time of 8 hours/car/day, the average stretch of road for movement is 32km/day (2 trips/day x 2 turns x 8km/turns). For this project, the exact number of vehicles and machinery in service of construction and construction time of each works will be determined during the phase of technical design and construction organization. The calculated results show that: - Dust and emission from vehicles of transporting materials mainly focuse on group of works under component 3( particularly with works for infrastructure construction at Hoa Phong resettlement site, Hoa Vang district) due to large volume of excavated soil and backfilling. - Dust and emission araising in component 1 and 2 is not large and local at each construction location. Moreover, construction works are allocated in huge scale, thus, impacts by dust and emission is estimated to be minor. Dust and emission will be mitigated maximum upon application of mitigation measures in Chapter 4(application general mitigation measures and specific mitigation measures for each construction location). Dust and noise caused by transport vehicles affect the communities living along the road. Increase in the density of vehicles traveling on the road can result in traffic accidents, traffic jam and degradation of road quality. Dust together with NO2, SO2, CO, THC and VOC emissions from transport vehicles will pollute the surrounding air, increase greenhouse effect, affecting air quality, which will impact on the environment, human being and creature However, in reality, transport vehicles circulate on different roads, depending on locations of work items and in different moments but not concentrate in a certain area. Process of exhaust emissions occur on the running path of vehicles and the project area has an average wind speed of 2,3 m/s, therefore, the exhaust emissions will easily spread far and do not cause serious impacts. The project owner shall require the construction contractors to take effective measures to minimize pollution of exhaust emissions from transport vehicles as specified in Chapter 4. Consultant: IAC Vietnam Page 110 Updated EMP Report – The Adjustment Works under the Danang SCDP For excavator, grader and bulldozers, etc., because there are a few devices and it is not concentrated in a certain area, it can be realized that the amount of waste emissions from burn fuel oil of these machinery is small The above-mentioned sources of pollution are temporary, intermittent, dispersed and depending on the intensity and duration of construction, number of motorized vehicles, and flow of people. Therefore, the impact on the environment is not great. At the same time, during the implementation process, the Employer requires the construction units to implement mitigation measures to limit pollution b. Noise During the construction phase, in addition to the above-mentioned impact on the air environment, noise is also an element of physical nature and affects the regional air environment. It mainly generates from the construction machinery, heavy trucks, generators pile driven machine, concrete breaker machine, bulldozer upon construction of water/ waste water drainage with big size, vehicles on construction sites ( transport materials, excavated soil/ construction soil), activities of pile drilling upon construction base. Noise generated at each group of work under components has different impacts and depends on construction items, location and progress, namely: - Group of works for storm water drainage system improvement ( 11 works)- component 1: Noise generated from construction of work is evaluated at average rate to people due to sewer system is located in residential sites and drainage system belongs to sidewalk of roads. The distance from works to households is from 5m to 10m (particularly distance at some locations is about 2-3m). However, construction items are quietly simple, equipments araising cause small noise. However, at Ong Ich Khiem pump station, impact caused by noise is evaluated at negligible level due to far distance from residential site ( about 300m) - Group of works for flood treatment at residential sites (01 work)- component 1: Impacts of noise to residents at these works are similar to group of works for storm water drainage system. - Group of works for waste water collection system construction( 04 works) – component 1: Majority noise from construction group of works have small impacts to residents due to distance from construction location to residential area is more 50m and equipments for construction generate small noise - Group of works for waste water treatment stations (02 works)- component 1: Noise impact on community at 2 construction works is evaluated to be minor due to far distance from residential area. - Group of works under component 2: Impact by noise from group of works under component 2: Impact by noise of this group of work is evaluated to be high level due to construction activities have to use equipments which generate big noise with high intensity. However, all these works will be equipped with fences by metal in order to mitigate noise to surrounding areas. - Group of works under component 3: Noise at this group of work is also evaluated to be at average level due to: (i) At Hoa Khuong resettlement area, construction equipments have araising level of big noise, however residential area is far from construction location about more 200m); Consultant: IAC Vietnam Page 111 Updated EMP Report – The Adjustment Works under the Danang SCDP Operation of machines only takes place in short time, not continuously within 2 weeks for each sewer (100m long). However, contractor should be pay attention to noise in the construction process. Some sewers are adjacent residential area, however, in fact, there are from 1 to 2 big machines operating, construction works are simple and avoiding implementing construction at night. (mainly excavators, rollers). Thus, affecting level of noise is minor, short-term and can be mitigated on the basis of compliance with ECOP. According to standard of Vietnam 26:2010/BTNMT, the highest noise level permitted is 70dBA in production area and the lowest noise level is 45dBA in health stations, libraries, sanatoriums, schools from 21h p.m to 6h a.m. Besides dust and fumes pollution source caused by excavating and backfilling, vehicles, earthwork for construction basement, operation machines and equipments such as bulldozers, compactor, crane, drilling, concrete mixer machine, excavator, truck… also cause noise pollution and vibratory. Noise level generated from construction equipments is shown in the following table. Resonance of noise level by many equipments operating at the same time is not considered.

It also reduces labor productivity of workers on the site, making them difficult in mental focus, easily resulting in occupational accidents. High-intensity noise will affect the daily life activities of the people (especially the farmers living along the routes of wastewater drainage which are renovated and upgraded). According to calculation and evaluation result, noise level at construction location is evaluated at medium rate and can be mitigated. Noise mitigation measures need to be implemented at all construction locations and informed to all communities about construction progress, time of construction items.( especially not constructed in the time of rest of people). c. Waste water During the construction phase, the sources of wastewater are mainly domestic sewage of workers, water pumped from the process of the works and runoff water through the surface of the project area Pollution caused by domestic sewage of workers Domestic sewage of workers at the construction site is a major cause of affecting water quality of the surrounding area. It many impurities, easily decomposable organic substances, nutrients and malignant bacterium, possibly resulting in contamination of surface water and ground water if not being treated promptly. Based on the amount of pollutants in the report on current situation of urban wastewater - Institute of Environment Science and Technology - Hanoi University of Technology in 2006, the amount of pollutants daily released into the environment by each person is given in the following table: Table 4-17: Amount of pollutants daily released into the environment by each person No Pollutants Volume (g/person/day) 1 BOD5 45 - 54 2 Suspended solid 70 - 145 3 Animal fats and vegetable oil 10 - 30 - 4 NO3 (calculated according to Nitrogen) 6 - 12 3- 5 PO4 (calculated according to phosphor) 0,8 - 4,0 6 Coliform 6 10 - 109 MPN/100ml Source: Report on current situation of urban waste water - Institute of Environment Science and Technology - Hanoi University of Technology in 2006 Consultant: IAC Vietnam Page 114 Updated EMP Report – The Adjustment Works under the Danang SCDP At each construction site, there are 20-50 workers involved in the construction of the project works ( for 21 construction works). Workers concentrated with the highest number in the first phase of the project and it will reduce after the project completion. With the water usage of 100 liters/person/day (According to Construction Standard 33- 2006), the amount of generated wastewater equal to 85% of the water supply (85 liters/person/day), total amount of domestic wastewater generated daily at the site is approximate from 1.7 to 4.25 m3/day. Load and concentration of pollutants in domestic wastewater in the project construction area is calculated based on the amount of pollutants, the number of workers, wastewater flow, the results of which are shown in the table below: Table 4-18: Load of pollution in domestic wastewater Load of pollution (kg/day) Pollutants 1.1 1.2 1.3 1.4 2.1 3.1 BOD5 15.59 6.44 7.92 4.95 9.90 2.48 TSS 33.86 13.98 17.20 10.75 21.50 5.38 Animal fats and vegetable oil 6.30 2.60 3.20 2.00 4.00 1.00 - NO3 (calculated according to 2.84 1.17 1.44 0.90 1.80 0.45 Nitrogen) PO43- (calculated according to 0.76 0.31 0.38 0.24 0.48 0.12 phosphor) Coliform 100x106 - 60x109 MPN/100ml Total of waste water generated 26.78 11.05 13.60 8.50 17.00 4.25 (m3/day night) Note: (1.1) – Group of works for storm water drainage system improvement, component 1; (1.2) Group of work for flood treatment at residential sites, component 1; (1.3) Group of works for waste water collection system construction, component 1; (1.4) Group of works for waste water treatment station, component 1; (2.1) Group of works under component 2; (3.1) Group of works under component 3. Concentration of pollutants in domestic waste water before treatment is calculated by the following formula: In which: - M: Concentration of pollutants to be calculated - m: Load of pollution (kg/day) in Table 4-18 - V: Total amout of waste water generated (m3/day night) The calculated result is shown in 4-19. Consultant: IAC Vietnam Page 115 Updated EMP Report – The Adjustment Works under the Danang SCDP Table 4-19: Concentration of pollutants in domestic waste water before treatment Concentration of pollutants Vietnamese code 14: No Pollutants in domestic waste water 2008/BTNMT before treatment (mg/l) (column B) 1 BOD5 582 50 2 TSS 1265 100 3 Animal fats and vegetable oil 235 20 - NO3 (calculated according to 4 106 50 Nitrogen) PO43- (calculated according 5 28 10 to phosphor) 6 Coliform 100x106 - 60x109 MPN/100ml 5.000 MPN/100ml It is shown in the calculated results in the above-mentioned table that pre-treatment domestic wastewater has much higher concentration of contaminants than the rating in the Vietnamese code 14: 2008 / BTNMT (column B). This waste water often contains suspended solid(ss), organic compounds (BOD, COD), nitrogen and phosphor as well as microorganism which need to be treated before released into the environment. If no daily appropriate management measures, these contaminants could be decrease environmental quality and affect on people health. This is a significant source of pollution, directly impacting on the living environment of the workers and the people living around the project area, causing epidemics and causing direct effects on the environment of underground and surface water. Despite this, the majority of wastewater focus on the first phase of the construction works (usually in quarter 2/2016). The amount of waste water will disperse over large spatial extent and lasting (about 30 construction site) so the actual amount of waste water ranged from 1.7 to 4.25 m3 / day. The amount of waste water will be reduced over time until the end of the project. Moreover, the amount of waste water was not entirely generated on site by using the local labor force in order to minimize the amount of wastewater generated. For the amount of waste water, the project owner will take the appropriate remedial measures specified in Chapter 5. Pollution caused by construction sewage During the construction, wastewater is generated from washing of materials, equipment, machinery, concrete curing, washing of wheels and so forth. The amount of waste water is approximately from 0.3 to 1.5 m3/day which depends on each construction site (21 construction sites). The amount of waste water by construction sewage is on average of 10.5 m3/day. This type of waste water is characterized by highly contained suspended solids and organic substances. Its composition is listed the following table: Table 4-20: Concentration of contaminants in construction wastewater Construction Vietnamese code No Indicator Unit waste water 40:2011/BTNMT 1 pH - 6.99 5.5 - 9 2 SS mg/l 663 100 3 COD mg/l 641 100 Consultant: IAC Vietnam Page 116 Updated EMP Report – The Adjustment Works under the Danang SCDP Construction Vietnamese code No Indicator Unit waste water 40:2011/BTNMT 4 BOD5 mg/l 429 50 5 NH4+ mg/l 9.6 10 6 Total N mg/l 49 30 7 Total P mg/l 4.3 6 8 Fe mg/l 0.7 5 9 Zn mg/l 0.004 3 10 Pb mg/l 0.055 0.5 11 As  mg/l 0.3 100 12 Oil and grease mg/l 0.02 5 4 13 Coliform MPN/100ml 53 x 10 5.000 Source: Centre for Environmental Engineering of Towns and Industrial Areas (CEETIA), Hanoi University of Civil Engineering (HUCE) It can be shown in the results of the table above that some quality indices regarding the construction sewage of the project exceeds the permissible limits of the Vietnamese code 40:2011/BTNMT – National technical regulation of industrial waste and the indices of the larger suspended solids, COD, BOD5 and Coliform are 6,6 times, 8 times, 8.6 times and 106 times higher than the permissible limits respectively. Although the amount of water is not much, it will still pollute sources of surface and underground water as well as workers’ health if not being collected, treated but discharged directly into the environment. Pollution caused by overflown stormwater Quality of overflow stormwater depends on the atmosphere purity and volume of washing substances on the surface of the project area. In the area of construction works, the quality of overflow waste stormwater sources only depends on the surface of the construction site because the current state of the air environment’s quality of the project area is quite good, possibly making sources of stormwater polluted in the area. Contaminants in overflow stormwater in the construction phase mainly consist of suspended substances, the oil and grease of which are swept away by stormwater. In particular, during this phase, the surface of construction plan is unfinished, easily resulting in washout and erosion of surfaces In order to limit contamination of overflow stormwater, the construction units need thorough collection of scattered materials and waste oil and grease of vehicles and machinery in the construction process. As a result, stormwater will not wash away many contaminants into the surrounding water sources, therefore, the impact is insignificant. d. Solid wastes Domestic solid waste During the construction, domestic solid wastes generating from the workers’ activities mainly are nylon bags, waste paper, food packs and so forth. Consultant: IAC Vietnam Page 117 Updated EMP Report – The Adjustment Works under the Danang SCDP Table 4-21: Concentration of contaminants in domestic waste water Weight Total volume of emission (kg/day) Components ratio (%) 1.1 1.2 1.3 1.4 2.1 3.1 Paper, packing, rice 30 24.8 2.7 10.8 9.0 9.0 4.5 box… Putrescible matter 25 20.6 2.3 9.0 7.5 7.5 3.8 (animals and plants) Glass 12 9.9 1.1 4.3 3.6 3.6 1.8 Plastics 10 8.3 0.9 3.6 3.0 3.0 1.5 Metals 6 5.0 0.5 2.2 1.8 1.8 0.9 Fiber pulps 2 1.7 0.2 0.7 0.6 0.6 0.3 Other inorganic 15 12.4 1.4 5.4 4.5 4.5 2.3 substances Total 82.5 9.0 36.0 30.0 30.0 15.0 Source: Center for Urban Environmental Engineering and Industrial Area – University of Construction of Hanoi Note: (1.1) – Group of works for storm water drainage system improvement, component 1; (1.2) Group of work for flood treatment at residential sites, component 1; (1.3) Group of works for waste water collection system construction, component 1; (1.4) Group of works for waste water treatment station, component 1; (2.1) Group of works under component 2; (3.1) Group of works under component 3 It is estimated that each worker working in the project area generates approximate 0.3 kg of domestic waste per day, on average, about 202 kilograms of domestic waste per day (total amount of waste generated in the construction process is estimated at approximately 58 tonnes), which will impact on surface water, ground water, causing unpleasant stench in the project area due to the decomposition and sweeping-away of stormwater, if not being effectively managed and collected. The difficultly decomposable inorganic wastes like bottles, nylon bags and other items existing in water will cause unaesthetic, affecting water quality and reduce the possibility of diffusion of oxygen into the water, which impacts aquatic life. Construction solid wastes Solid wastes generating during the construction are mainly: cement bags, grout spillage, rubble, scrap steels and so forth. The volume of generated solid wastes is dependent on many factors as the construction and project management regime, the supply of building materials, etc. Total volume of soild waste generated in the construction includes: - - Approximately 11,000 m3 sludge from dredging storm water and waste water drainage system and 02 outlets of My An and My Khe. - - Approximately 90,694 m3 excavated soil and backfilling from construction work items and ground leveling. In addition, amount of soil creating from the excavation of foundation pit is also significant. It can be used for embankment, backfilling around the foundation pit and landfilling of the foundation pit in the future.. Consultant: IAC Vietnam Page 118 Updated EMP Report – The Adjustment Works under the Danang SCDP Hazardous solid wastes Maintenance of facilities, vehicles, and machinery in service of construction can also generate residue oil, oil bottles and containers and oil rags and forth if it is done rightly on the construction site but not collected and treated, which will affect the landscape and pollute the surface water and ground water in the project area. However, contractors only implement minor reparing operations on sites( eg oil change, on average 01 time of oil changing is 16liters/vehicle, oil change cycle is from 3-6 months depending on the intensity of the operation of machinery and equipment). All major repairs of equipment, machinery maintenance are carried out at repairing center. The Employer will take measures to collect and treat it according to the regulations on hazardous wastes to minimize negative impacts on the local environment. On the other hand, another hazardous waste source during the construction of road is residual asphalt during the spreading asphalt and a small amount of welding rod generated - Asphalt is a liquid or semi-solid with highly viscousity and black color. Asphalt is a petrochemical product, it may danger or cause adverse impact on the environment and human health if it is not properly stored and used according to technical processes. In particular, if the compact asphalt is regularly stored at high temperature, it can cause the risks of fire, explosion or burning during the transport and using. Essential component of asphalt is bitumen. - Therefore, it is required to collect and store residual asphalt in dedicated tanks of hazardous waste. The Client and Contractor need to hire an agency for transporting and treatment in accordance with regulations on hazardous waste management to prevent risks of environmental pollution. - Welding waste generates at each site due to activities by forming the steel frame. However the amount of welding rods arising intermittently and mainly focused on the first phase of the construction works. Welding rod is estimated to be an average waste on each site is 3-5 kgs / month. This amount of welding rods will be collected by workers and bring them to gathered areas for hazardous waste in accordance with regulations. e. General other impacts Impacts due to crowded construction workers During the construction in the project area, the gathering of construction machinery and about 675 labors at the construction site will cause certain disturbance to the area, in particular: - Demand for regional goods such as food and utensils will increases. - The relationships between the workers at the construction site and the local people will arise. Possibility of conflict between the workers and the local people will be higher if the workers are those who come from other regions do not understand the customs of the local people. - During the construction, the concentration of a large number of workers will increase the risk of social evils (gambling, theft, drug addiction, prostitution, etc.) and order and security situation will become more complex and difficult to control, making it difficult for the local police. - In addition, the concentration of workers in the construction area will also contribute to appear and spread outbreaks of waterborne diseases (cholera, dysentery, typhoid, diarrhea) or through intermediate vectors (fever malaria, dengue, etc.) as well as social Consultant: IAC Vietnam Page 119 Updated EMP Report – The Adjustment Works under the Danang SCDP diseases (gonorrhea, syphilis, HIV, etc.), affecting the health of the local communities. This effect will be likely to occur if no management and control measures are taken. Impacts on health and safety of workers and local residents Increased circulation of transport vehicles of construction materials and heavy machinery will affect the safety of the drivers and the road users on the transport roads. Generation of dust and noise from the vehicles in circulation can seriously affect human health directly or indirectly through food. Pollution-based pathogen can spread immediately or accumulate for a period of time and then appear. In addition, during the leveling and construction, the fires of temporary electrical systems, explosion of fuel depots and so forth as well as the excavation and embankment of roadbeds can cause landslides and subsidence of adjacent buildings, effects on the underground water level. Besides, the Employer and the contractors will work closely with the local governments in the project area and the relevant agencies to promptly solve the arisen problems in accordance with the state regulations the people’s aspirations. Impacts on the health of construction workers The construction units will set up temporary or hire the local people’s houses for their workers to sleep, stay and rest in the far distance from the construction site, therefore, dust, exhaust gases, noise, soil and rock of excavation and leveling, etc. will have no impact on the health of construction workers in their leisure time. The effects mainly occur when the workers are present on the construction site. However, the construction workers are arranged to work in shifts in the construction site with appropriate works and issued suitable protective cloths, equipment so the impact levels of waste such as dust, emissions, noise can be reduced are controlled. Sewage and garbage of the construction workers can be pathogenic sources for them if not being collected and treated appropriately On the other hand, soils and rock excavated and backfilled during the construction can cause accidents (slip, trip and fall, etc.) for the construction workers if being not removed to the appropriate locations Divides communities and temporary impact on transportation During the construction phase, the existing local roads may be temporary congestion. At this time, collection road system and underground are not built. Some existing routes, roads will be used for civil service road. The operation of vehicles / machines with high frequency on these routes will damage the roads. Sandy soil dropping from shipping process of excavated soil to works will make roads muddy, cause dust in the dry season and muddy in the rainy season. The intensity of impact, the impact level will depend on management capacity of construction site, the level of compliance mitigation measures by contractors. - Group of works for renovating stormwater system (11 works) - Component 1: In this work group, impact on travel of local communities is assessed from medium to high level, so the works mostly take place in residential areas. For renovation projects for 6 urban drainage sewers, namely Tho Quang- Bien Dong sewer system, Le Tan Trung sewer, Me Linh sewer and sewer from lake of Park to Le Do sewer impact level is high due to construction activities taking place in crowded residential areas or across the Consultant: IAC Vietnam Page 120 Updated EMP Report – The Adjustment Works under the Danang SCDP road. However, traffic operations are mainly bicycles, motorcycles and frequency of traffic is not large, congestion is insignificant, but people will have difficulties in the process of moving due to small area, large volume of construction materials. However, Ong Ich Khiem anti-flood station has insignificant impact due to adjacent to coastal, far from residential areas. - Group of works for flood treatment at residential areas( 01 work)- component 1: Work of flood treatment for groups 5,6,7 Son Thuy, Ba Bang Nhan road, Dang Thai Than is assessed to be high level due to location is in residential area. - Group of works for wastewater collection system construction (04 works) - Component 1: In this work group, impacts on traffic are evaluated in small level due to the majority of works away from residential areas, large construction scope - Group of work for waste water treatment station ( 02 works)- Component 1: Impact on transportation at 02 works is assessed at a small level due to far distance from residential areas. - Group works under component 2: The impact on the group's traffic works are assessed at a high level due to high turns of vehicles transporting materials and at construction site or traffic intersections, many traveling activities of people take place. Contractor should note the impact of traffic in this component and take appropriate mitigation measures. - Group of works under Component 3: Impacts on traffic in this work group are also evaluated at medium level due to: (i) Although Hoa Phong resettlement area away from residential areas, high density of transporting vehicles of materials; f. General isks and incidents  Soil excavation Most construction works are related to some form of digging foundations, sewers and underground works. Soil excavation and trench digging can be very dangerous and even some of the most experienced workers also have incidents with not reinforced trenches. If workers are buried under a cubic meter of soil which is equivalent to weight of a ton of gravel, workers will not be able to breathe because of the pressure on their chest and external physical trauma will make the body to be suffocated quickly and have death. Earthwork is also related to the disposal of volumes of soil and rock. The presence of water always should be concerned even if it exists in the moisture in the soil, in a heavy rain, which would cause the risk of landslides. Therefore, the possibility of flooding and other risks are always in need of attention. Cracks which are caused by liberation soil pressure, should be remedied or not to dry out in hot weather. Soil may be changed according to their natural status (eg fine sand can flow easily or hard clay is more coherent). However, any type of soil could not stabilize if only based on specific gravity itself, thus, it is necessary take preventive measures to prevent the subsidence of the pit if its depth is greater than 1.2m.  Landfill or underground works Before workers do anything of digging, by hand or with an excavator, it is noted that there may be underground works beneath the surface. In the construction areas, it is always supposed that underground works exists such as electrical cables, water supply and drainage pipes. These types of services have similar construction methods, so the ability to find workers buried is considered as the worst supposition. Incidents are electrocuted by underground power cable which can cause death or some accidents due to electric shock or Consultant: IAC Vietnam Page 121 Updated EMP Report – The Adjustment Works under the Danang SCDP fire incidents. If clean water pipes and drainage pipes are ruptured, they could cause local flooding for areas of earthworks or cause pits subsidence.  Working on water surface Falling into water and being drowned or swept away area considered as a risk when working on or adjacent to water. Even if workers are a good swimmer, the following warnings should always be observed: - Do not work on water surface alone. - Check the rules of work to ensure that there are no rules flawed.  Manual tools There are many different types of manual tools for different types of work, such as shovels, axes, crowbars, chisels, screwdrivers, hammers. In many cases, these tools are purchased from an external supplier, it should pay attention to quality or design. A manual tool of good quality should be designed in accordance with the hands and available functions. It will increase your chances of earning money and reduce the ability accidents. With well- designed manual tools, work will be improved and pressure will be relieved , as a result, work efficiency is increased. The accidents caused by manual tools often arise due to carelessness of users, using of inappropriate tools or neglecting safety warnings or improper maintenance of tools. Therefore, users need be guided and know how to maintain tools properly.  Working in hot weather Workers on construction sites often have to work under all different climate conditions. In tropical countries, under the sun with high temperatures and humidity along with heavy workload, it can cause exhaustion due to heat and sunstroke, some cases of emergency have to taken to the hospital or taking disease. Effect of heat combined with physical workload tends to accumulate. Hence, the need for a regime of healthy welfare in hot climates and suitable arrangement with time is an important work.  Chemicals and impact level Many hazardous chemicals can cause fires, explosions, toxic, with potential and can cause poisoning. Hazardous chemicals cause acute effects, such as nausea, dizziness and headaches due to exposure to solvents in a short time and chronic effects due to exposure in a long time as lung diseases, namely asbestosis and silicosis. Dermatitis can result from contact between skin and some chemicals. In addition, acid and corrosive alkali can damage skin and eyes.  Traffic accident The basic cause of most traffic accidents on the construction site is the failure to implement the plan of work safety systems and the methods of training workers. However, the common direct causes are the combination of one of the following elements: - Driving technique limitations; - Careless or negligence for special hazard sources,namely working near power lines or landfills; - Transportation of passengers without registration; - Maintenance of incomplete vehicles; Consultant: IAC Vietnam Page 122 Updated EMP Report – The Adjustment Works under the Danang SCDP - Overloaded or poorly loaded; - Obstruction of the construction site; - Poor transport surface; - Lack of proper road (bypass) or rough pavement.  Toxic chemicals Cement: Cement mixture is considered as a common cause of skin diseases. Both irritant and allergic contacting dermatitis may have derived from wet cement. The long term exposure to wet cement (for example, if you kneel or stand in it) it can cause cement burn or skin ulcers. Lead: Inorganic lead is used in many construction products, such as cables, pipes, water gutter and old roofs with thin shell. Organic lead in engine fuel and storage tanks with huge pollution amount Risks affect health by inhalation of dust or fumes created by burning or cutting of lead- containing materials, including painted surfaces, welding, grinding or cutting, painting spray with leaded paint . Lead can be absorbed in the case of being swallowed, the food is often contaminated and should be provided adequate washing facilities. Organic lead compounds may be absorbed through skin easily. Excessive lead absorption causes constipation, abdominal pain, anemia, weak muscle and kidney damage. It can also affect the brain, causing mental decline, strange behavior, fainting and coma.  Treatment process for objects finding in excavation process In the construction process, objects findings have cultural value or be dangerous, it is necessary to take actions promptly, these actions are metioned in details in the following table: Table 4-22: Process of objects finding No Situation Action Implementation responsibility 1 Finding Contractors protect current status for the Contractor, cultural/ construction area and report to Construction Monitoring archaeologi Supervisor / PMU, local museums and Department Consultant cal objects/ of Culture and local information coordinates for in the Submission of objects for the museum / cultural implementation process of management agency Contractor soil Review to determine if the excavation has been Department of excavation continued or stopped to survey more Culture and Director of Department of Culture and Information Information in the locality will be responsible for managing the objects under the Law on Cultural Heritage 2 Finding Protect current situation and notify local authorities Contractor, tomb in the Determine how to resolve and duties of the relevant process of individuals involved, time of implementation and agencies soil relocation sites if any excavation Implementing proposed measures 3 Finding Protect current situation Contractor explosive Notify to local authorities coordinates with materials Contact with military units at local for supporting local authorities requests Consultant: IAC Vietnam Page 123 Updated EMP Report – The Adjustment Works under the Danang SCDP 4.2.4.

Homogenerous engineering geological with sand embankment do not facilitate during construction, it is easy to generate quicksand foundation subsidence. Thus, geological survey work to assess hydrological ground in the expected ground construction area is necessary. - Water pollution : Characteristics of the construction on the beach, so the risk of seawater contamination is inevitable. The degree of contamination depends on the construction method. 1.1.2 Construction sewer system from lake Sewer system connecting from lake of Park of Park 29/3 to Le Do sewer 29/3 to sidewalk on Nguyen Tri Phuong road, to Dien Bien Phu- Nguyen Tri Phuong crossroad, across the road, then connecting with sewer system on Le Do road. In the process of construction, it may cause: - Cracking down underground works: water supply pipelines, electricity cables, communication cables or pipelines ... crossings or adjacent pipeline; Consultant: IAC Vietnam Page 124 Updated EMP Report – The Adjustment Works under the Danang SCDP No Works Site specific impacts - Cracking down roadbed due to subsidence; cracking down houses near deep excavations location, poor ground. - Causing traffic jams at the roundabout during rush hour. 1.1.4 Improvement Me Linh sewer(1.1.4) - Me Linh sewer is located in alleys in a residential area, thus in the process of construction, it will affect the movement of people. Odor when flipping the drain cap also affects the health of people around the construction location. - Narrow construction location is also an obstruct in the process of construction. 1.1.5 Construction Le Tan Trung sewer - Located in alleys in a residential area, thus in connecting Tho Quang – Bien Dong the process of construction, it will affect the sewer movement of people. - Narrow construction location is also an obstruct in the process of construction. Sub project 1.2: Flood treatment at residential sites 1.2.1 Flood treatment for groups 5,6,7 Son - Local flood: Thuy + Currently,Ba Bang Nhan and Dang Thai Than roads are penetrate plastic roads, the rest are cement concrete road in the alleys. The roads have no sidewalks, no drainage system, trees, ... Stormwater and wastewater mainly self-absorbed and self-flowing into natural terrain on local points near Le Van Hien road. + Due to the low background of the region, steep slope from the Co Co River towards Le Van Hien road, thus, in the rainy season (October-December) the whole area of group 5,6,7 Son Thuy and 2 routes are flooded. Thus, the process of construction should avoid the typhoon season, it should apply a rolling construction method, quickly, avoid prolonged construction period Subproject 1.3 : Construction waste water collection system 1.3.1 Improvement landscape for outlets of Due to location of 2 outlets is near the coast, My An and My Khe thus, in the construction proces, there will be the following site specific impacts: Consultant: IAC Vietnam Page 125 Updated EMP Report – The Adjustment Works under the Danang SCDP No Works Site specific impacts - Construction on subsidene- prone sand or collapse the building foundation - The risk of coastal water pollution caused by the temporary operation of construction machines and equipment. - Influence temporarily to recreation activities, entertainment of local people. - Waste water from outlets of My An, My Khe is not collected, then with storm water flows over beach causing environmental pollution, landscape. 1.3.2 Collection waste water around Hoa Phu lake and Hoa Phu canal to Hoa Minh lake For this work, implementation construction drainage system around Hoa Phu lake( not dredging the lake), Impact is within ECOPs scope I.3.3 Collection waste water for Pham Van - It should take safety measures during Xoa road, Tho Quang industrial zone construction to avoid cracking existing pipeline. - A volume of dredged sludge from this work item implemention, estimated to be approximately 340 m3. - Impact is within ECOPs scope.

Consultant: IAC Vietnam Page 126 Updated EMP Report – The Adjustment Works under the Danang SCDP 4.2.4.2. Site specific impacts of Component II Adjustment for construction location of Depot station near airport area The project area is located in the residential area. At the work's location, at rush hours, number of vehicles traveling remain high rate. There are no construction of high works with large-scale, no construction activities on high and deep scope, thus, construction activities during construction should just use some simple machinery / vehicles, mainly as excavators, bulldozers and other handheld devices. However, the process of construction should be noted a number of problems: Traffic safety, traffic congestion: due to the location is near densely populated areas, in the process of transporting construction materials, it can cause traffic accidents or traffic jams during rush hours. Figure 4-1: Construction location of Depot station at airport area Construction Dien Bien Phu underpass(2.1) In the process of construction, the largest site specific impact of this work is - Impact on drainage system beneath sidewalk, roadbed - Impact on some business households (due to limit of vision, dust, noise, difficulties for customers) - The risk of subsidence of surrounding buildings, households (in terms of geological processing, works topography does not ensure structural engineering). - The potential of risk of local flood in underpass digging( due to heavy rain, high underground level). - The potential risk of traffic safe, traffic accident due to narrowed roadbed, traffic conflicts at rush hour, materials In addition, construction Dien Bien Phu underpass have no relocation of electric poles, works adjacent the project area. Consultant: IAC Vietnam Page 127 Updated EMP Report – The Adjustment Works under the Danang SCDP Figure 4-2: Dien Bien Phu - Nguyen Tri Phuong crossroad 4.2.4.3. Site specific impacts of Component 3 Site specific impacts of Hoa Khuong resettlement( 3.1) For construction of Hoa Khuong resettlement area, apart from the impact due to compensation, site clearance and resettlement. During the construction process, there are some special impacts such as: - Concentrated labor force for construction: It can generate social evils, conflicts with local residents. - The volume of excavated soil and backfilling is relatively large (400,000 m3) - Currently, agricultural land accounts for the highest rate (51.35%), followed by residential land (253.53%), vacant land (16.04%) and other land. According to monitoring results, ( D1 sample in Table 2-14) the land in this area has no signs of contamination. indicators (As, Hg, Fe, Pb, Cu) are within permissible limits for agricultural land and can be used for leving other low-lying areas. - Remaining volume of excavated soil and backfilling soil should be monitored for used materials to be exploited at permitted mines. 4.2.5. Impact assessment in the operational phase In the process of project operation, negative impacts in the construction phase will be disappear, and positive impacts will be replaced. The new negative impacts will arise during operation process. The objectives of works coming into operation are different, thus, negative impacts during this phase are mainly special impacts. The impacts will be analyzed by the group of the same nature, scale ... to assess. 4.2.5.1. Impacts in the operation phase under Component 1 Groups of work have impact in the operational phase including: 05 works of storm water collection; 03 works of waste water collection; 02 works of waste water treatment Works of waste water and storm water collection ( item 1.1, 1.2 and 1.3) Odor from waste water collection and treatment system For drainage sewer system, although drainage sewer system is designed by cleft to prevent but actually, in the dry season, water in the slot to prevent odor is evaporated. In the FS period, new designs focus on determining alignment s and size of sewer. A technical solution to Consultant: IAC Vietnam Page 128 Updated EMP Report – The Adjustment Works under the Danang SCDP prevent odor in the gas hole will be further studied and completed in detailed design phase. This request will be mentioned in the TOR for the detailed design stage. In general, seperate wastewater collection system, odor will be reduced over the entire drainage system and outlets, the previous wastewater receiving location. However, at these locations, as well as region of 2 wastewater treatment plants will generate odors (mainly H2S ingredients), may affect households adjacent to this location. Sludge/ sediment dredged from storm water, waste water drainage system Sand sludge (sediment) by runoff stormwater, deposition in storm water drain system: It is estimated in 2018 (after the project comes into operation), the total amount of sewage sludge to be dredged is approximately 11,000 m3 / year, of which sludge in stormwater drainage sewers accoun for 90%, corresponding to about 10,000 m3 / year. Average per month, there will have approximately 100m3 of sewage sludge / canals need to be collected and disposed. Currently, sludge is contaminated by waste water flowing in the sewer. However, when the project is completed, waste water will be collected and treated by separate systems. Water in sewer is just storm water, sediment / deposition sludge will be cleaned regularly. Sewage sludge from wastewater collection works: according to design calculation there is a manhole built for each 30m of wastewater collection line. Thus, the length of pipelines with 1, 2, 3, approximately 63,000 m, corresponding to around 2,100 manholes to collect sludge from wastewater collection system (construction of 06 wastewater collection works). The size of manhole is on average of (0.8 x 0.8 x 1.2) m. Thus, volume of sludge from wastewater collection works system (is collected 2 times/ 1 year) is estimated at 3,200 m3 / year, an average of about 270 m3 / month. The amount of sludge will be collected and treated by urban environment company of Danang city and in accordance with regulations periodically on the management of hazardous waste according to Circular No. 36/2015 / TT-BTNMT. Flood in the operational process of storm water and waste water system Without maintenance, storm water and waste water drainage system will be degraded, clogged, causing flood incident and environmental pollution. Impacts in the operation phase of Ong Ich Khiem station The concerned issue in the operational phase of Ong Ich Khiem pumping station is the possibility of affecting biodiversity (conservation of coral reefs and related ecosystems) when the station is put into operation. To assess impact of this effect, the Consultant and the representative of the Client have conducted a survey to the pumping station construction location and referred to materials related to management and biodiversity conservation in the project area. After surveying and research, we come to the following conclusions: - Location of the pump station is 1604'50,4 '' - 108012'39,59'. This location is not in the scope of management area for the coral reefs conservation and related ecosystems from coasts of Hon Chao to Southern Hai Van and and Son Tra peninsula (under Decision No. 54/2007 / QD-Committee dated 13/9/2007 of the Danang CPC. Danang CPC promulgates regulations on management and conservation of coral reefs and related ecosystem). - According to the distribution maps of aquatic vegetation at Danang Bay (see Appendix 1), coastal areas of Ong Ich Khiem pumping station has almost no distribution of coral and seaweed. Consultant: IAC Vietnam Page 129 Updated EMP Report – The Adjustment Works under the Danang SCDP - On the other hand, as described in project description, the pump station works only in the case of high tide and heavy rain, at that time, the sluice gate will be closed to prevent water from overflowing from the bay back into the sewer, pumping station will be activated and pumping stormwater out. In normal conditions, the station will not operate, stormwater runs by gravity in the sewer system in the absence of tides, surges in Danang Bay. Hence, influence level of the pumping station is inconsiderable. Thus, it can be concluded that during the operation phase, Ong Ich Khiem anti-flood pumping stations has no impact on biodiversity Waste water treatment system of Hoa Xuan and Lien Chieu (item 1.4) Sludge from waste water treatment system Lien Chieu and Hoa Xuan. Sludge volume is expected to be collected during the 2 treatment plant operation calculated on the following table: Table 4-24: Estimated volume of sludge generated to be treated from waste water station Lien Chieu Emission Unit Hoa Xuan station Area station coefficient[1] Q(m3/day) 20,000 60,000 20,000 Sand sedimentation 0,005 m3/1,000 m3 m3/day 0.1 0.3 0.1 tank Trash crack 0,05 m3/1,000 m3 m3/day 1 3 1 Raw sludge from SS Input: 176 mg/l kg/day 1,760 5,280 1,760 suspended solids Efficiency: 50% Redundancy Al and 17 g/m3 kg/day 340 1,020 340 polyme[2] BOD5 Input - Biological sludge Output = 154mg/L - kg/day 2,480 7,440 2,480 productivity[3] 30 mg/L The total amount of sludge not kg/day 4,580 13,740 4,580 dehydrated Sludge is supposed to be dehydrated Volume of sludge kg/day 687 2,061 687 from moisture of reduces 15%. 90% to 35% Sludge volume / 365 ton 251 752 251 year Reference [1] Metcaft and Eddy, 2000; [2] EIA Report of CEPT, 2008; [3] CDM,2011 The total amount of sludge generated from the two waste water treatment stations coming into operation following is about 1000 tons / year (dry pressed). Thus, on average/ day, about 2.73 tons of dried sludge to be dumped. 02 wastewater treatment works for Lien Chieu and Hoa Xuan will generate sludge in the operaion phase. In the process of wastewater treatment, sludge will be generated with the following composition: - Total volume of solids Consultant: IAC Vietnam Page 130 Updated EMP Report – The Adjustment Works under the Danang SCDP - Concentration of pathogenic bacteria - Concentration of hazardous organic substances - Receiving ability of soil - Concentration of heavy metals Volume of sludge will be dried after sucking up. Ordor will possibly generated, spread to surrounding residential areas which affects the lives of people and workers in the factory. Sludge contains hazardous substances if not treated carefully, it will also contaminate soil, water and air. To mitigate these impacts, the following measures will be carried out during the implementation of this subcomponent. The risks and incidents during the operation of 02 wastewater treatment plants: After completion of WWTPs an the facilities are in operation, the wastewater generation from the service area will be treated and the overall sanitation and water quality in the area will be improved. However, there are risks on the following: - Treated wastewater discharge below specified quality standards; - Plant operated in appropriately; - Sludge from treatment process allowed to remain on site, or discharged other than in a prepared sanitary landfill; - Plant failure results in contamination downstream, causing health and other impacts on the population living along the waterway into which the plant discharge; The risks and incidents mentioned above all cause environmental pollution and affect the health of workers and plant operators as well as the people living around. At the same time, the amount of untreated wastewater discharged into the environment will affect the quality of the receiving water bodies, aquatic ecosystems downstream of the plant and other purposes of water use. The measures of responding and troubleshooting from wastewater treatment system will be proposed in Chapter 5 of the report. 4.2.5.2. Impact in the operational phase Component 2 Development Bus Rapid Transit (BRT) Waste water from Depot transit station near airport area Waste water generated from Depot station is mainly domestic waste water by operational workers and a small number of passengers at Depot. Thus, The wastewater will be treated strictly before discharging into the combined sewers of the City. Risk of fire and explosives at Depot station In addition, incidents of fire and explosives can be the risk during operation phase. The reasons include: - Fire due to short circuit in operation; - Fire and explosion caused by wrong placing of gasoline and raw materials, carelessness in the management process; Consultant: IAC Vietnam Page 131 Updated EMP Report – The Adjustment Works under the Danang SCDP - Fire due to too old operation equipment or lack of routine maintenance. The mitigation measures will be proposed in Chapter 5 of the report. Local flooding in interchange of Dien Bien Phu- Nguyen Tri Phuong tunnel When Dien Bien Phu tunnel comes into operation, if the maintenance work is not carried out fully, the stormwater system operations less efficiently, resulting in stuck of rain water will cause local flooding in the tunnel. 4.2.5.3. Impact in operation phase of Component 3 For works under Component 3 of the project, sources of causing impacts on environment in operation phase are mainly positive as the project achieves its objectives: mitigation of flooding in residential areas, strengthening water supply system, completion of infrastructure, urban adjustment… However, the major effect of the Component 3 is in the resettlement area of Hoa Khuong after being put into operation (fill in the number of households in the resettlement area). Impacts of wastewater: Estimated average number of household members is 4 persons. The demand for water is 200 liters/person/day. The amount of emissions is calculated by 80% of water supplied. The total volume of wastewater: 200 households x 4 persons x 200 liters/person/day x 80% = 128,000 liters/day (equivalent to 128 m3/day domestic wastewater). Impacts of domestic waste from households: Estimated amount of domestic waste generated is 0.5 kg/person/day. The total amount of household waste generated: 200 households x 4 persons x 0.5 kg/person = 400 kg/day. The amount of wastewater will be collected according to common sewer system of the city, conveyed to the planned wastewater treatment system in Da Nang City to be treated before discharging into the environment. The domestic waste of the people will be collected and processed daily by Da Nang Urban Environmental Company.

MITIGATION MEASURES FOR ENVIRONMENTAL IMPACTS To minimize environmental and social impacts, the project will access to following groups: - 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 EIA 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: The detailed environmental mitigation plan, Compensation and resettlement plan. These measures will be integrated into the Construction Contractor’s technical criteria of environment supervised by the environmental monitoring team as a part of the process of construction technical monitoring 5.1. GENERAL PRINCIPLES This program identifies measures to minimize the impact of adjusting and supplementary items during the process of preparation, construction and operation phase. Measures to minimize the overall impacts which are presented in the table ECOPs; and it will be applied to minimize the overall impacts of the project. For site specific impacts at specific locations of each group of works, it should take their own mitigation measures in these positions for both construction and operational phases apart from general measures identified in ECOPs. 5.2. MITIGATION MEASURES IN PROJECT PREPARATION PHASE a. Mitigate impacts due to land acquisition and site clearance The Project acquires land of several surrounding works, including residential areas 5, 6, 7 Son Thuy, bus terminal station near airport area, Hoa Khuong resettlement area (see more details in Table 4.2, Chapter 4). For land acquisition, affected persons are entitled to compensation policies (compensation and support), complying with provisions of Vietnam and WB. In some specific cases (extremely poor households or households under treatment policy), it requires a confirmation of local authorities, then submitted to Compensation Committee for review and apply additional supports for each case. Resettlement area of the project will be built in Hoa Khuong commune with total area of 8.42 hectera. Income recovery program of Da Nang SCDP will concentrate on 2 sectors: (i) vocational training and (ii) employment recommmendation. b. Impact mitigation due to bomb, mine, explosive objects clearance Consultant: IAC Vietnam Page 133 Updated EMP Report – The Adjustment Works under the Danang SCDP The UXO remove activities need to complete before starting construction activities, the several step should follow during UXO remove. Coordinate with the appropriate agencies at the design stage to identify if UXO is a potential threat to works. According to a preliminary report, bomb clearance is required to carried out in the following locations: - Construction of anti-flood pump station at the end of Ong Ich Khiem road - Construction of Lien Chieu WWTP - Construction of Bus Rapid Transition Depot (BRT) near airport (bordering Nguyen Tri Phuong intersectino and Nguyen Van Linh road). - Dien Bien Phu overbridge - Technical infrastructure construction of group 5,6,7 of Son Thuy commune. - Technical infrastructure construction of Hoa Khuong resettlement area.

PROGRAM OF ENVIRONMENTAL MANAGEMENT AND MONITORING Based on the assessment of potential negative impacts referred to as in Chapter 4 and the mitigation measures proposed in Chapter 5 above, this chapter will present Environmental Management Plan (EMP) for the works of the amended and supplemented items for the sustainable development project of Da Nang City (SCDP). EMP determines the actions to be implemented under the items in the environmental monitoring program and implementation organization, to ensure that the requirements in line with the Government’s EIA regulations and the (WB) World Bank's safeguard policies, including instructions on Environment, Health, and Safety of the Group of World Banks. 6.1. PROPOSED MITIGATION MEASURES The mitigation measures of the negative impacts of the phases of the project are divided into two basic parts: (1) The typical mitigation measures - ECOPs - for all construction activities of the project and (2) The specific mitigation measures for each works item. - (1) ECOPs: the environment code of practices (ECOPs) in the urban construction outlined the typical effects at the low levels that can occur in a series of construction activities of the project. ECOPs also include mitigation measures to these impacts and a procedure to include the mitigation measures into the construction contracts of the contractor. In the detailed design phase of technical solutions for each contract, the technical design consultant will include specific parts of ECOPs into the contract matching with such contract, as well as specific measures determined in the Environmental Management Plan (EMP). - (2) The individual/specific mitigation measures at per position of the project, but the mitigation measures are not included in the general ECOPs or these impacts happen at the level which requires other mitigation measures beyond range of ECOPs, will be described in more detail in the EMP. The activities are done to minimize the negative impacts caused by land acquisition and resettlement presented separately (as in the resettlement plan) and they are also carried out and monitored separately. 6.1.1. General mitigation measures Environment Code Of Practices (ECOPs) As a part of the Environmental Assessment, Environmental Management Plan (EMP) is a unique safety tool which is often used in many projects. EMP contains information and instructions for the process of mitigating and managing of adverse environmental impacts during the project implementation. ECOPs is a combination of mitigation measures for the general impacts arising from the activities of the project during construction and attached in the construction bidding documents as a obligatory requirement for the construction contractor. ECOP is not a safe tool officially recognized by the World Bank, but it is still used as a part of the Environmental Management Plan (EMP) for the usefulness and effectiveness to ensure the general impacts and typical activities from the project construction process minimized in an appropriate manner during the project implementation. The main environmental and social impacts in the construction process of urban works: Consultant: IAC Vietnam Page 148 Updated EMP Report – The Adjustment Works under the Danang SCDP The content of ECOPs is limited to construction activities on the small and medium construction impacts, with limited scope, the impact occurs temporarily and can be recovered and managed easily with good construction techniques. The environmental and social issues within this study include: - Dust - Air pollution - Impact of noise and vibration - Water pollution - Control of sludge and sewage - Management of stockpiles, quarries, soil mining areas - Solid waste management - Management of dredged sludge - Shuffling vegetation cover and ecological resources - Traffic management - Obstructing the utility services - Rehabilitation of the affected areas - Safe for communities and workers - Contacts with the local community - Opportunities of discovery of cultural, archaeological artifacts Table 6-1:Environment code of practices for urban projects (ECOPs) Environmental Vietnam's and social Mitigation measures regulations issues Generation of The Contractor is responsible for compliance with the QCVN dust requirements corresponding to Vietnam's regulations on 05:2013/BTNM ambient air quality.

ENVIRONMENTAL MONITORING PROGRAM With the impact of adjustment, supplementary items of SCDP the project in the phases of pre- construction, construction and operation mentioned above, adjustment, supplementary items require an environmental monitoring program in order that the mitigation measures are performed most seriously by related units. It is necessary to make the design of the program and the frequency of monitoring to be able to indicate the general operation of the project as well as the short-term impacts in the peak construction activities. More specifically, it is an important and indispensable part in the environmental management program. Purposes: - To determine the actual scale of the impacts. - To control impacts arisen during the construction of the project mentioned in the report of EMP; Check the pollution standards outlined for the project during construction. - To check and supervise the enforcement of environmental protection measures during the construction phase on the basis of the report of EMP appraised. - To make the additional recommendations to strengthen mitigation measures when the impacts arising or not be predicted. - To recommend to the project owner, to be in collaboration with the central and local environmental organizations to resolve the outstanding issues related to environmental protection under the responsibility of the project. - To evaluate the effectiveness of mitigation measures in the phases of pre-construction, construction and operation of the project. Contents of environmental monitoring will be carried out during the construction and operation of three levels: - Monitoring the level of compliance of mitigation measures; - Monitoring the popularization to the community; - Monitoring the environmental parameters; Details of the monitoring programs will be presented in the following sections: 6.2.1. Monitoring the compliance levels of mitigation measures of the impacts The monitoring duties of the contractor, construction monitoring consultant (CMC), EMC will be specified in their terms of reference and contract documents will be approved by the World Bank. Construction monitoring consultant (CMC) is responsible for submitting monthly reports on environmental issues, actions and monitoring results updated. Basing on the monthly reports and the field monitoring tests, EMC shall prepare and submit semi-annual reports to SLUDGEP to summarize the environmental issues and mitigation measures applied. Monthly reports will include: - List of priorities identified in the last month monitoring report. - The measures are done by the contractor to solve the arisen problems. - The appropriately unresolved problems and suggestion of handling measures and explanation of the force majeure cases. Consultant: IAC Vietnam Page 169 Updated EMP Report – The Adjustment Works under the Danang SCDP An independent environmental monitoring consultant will provide technical assistance and necessary guidance to PPMU and CMC to support their role in monitoring of mitigation measures and the related reports. 6.2.2. Community-based monitoring The Community will monitor under the project progress to ensure that the Contractor’s construction does not violate the regulations on environment, sociality, the principles of the environmental safety as well as to minimize the risks to property, people's health and reduce environmental destruction. By making the information, the community will help assessment of the mitigation measures as well as concerning about the aspirations of the people, contributing to an environmental management mechanisms heartily. The community-based monitoring forms a spirit of voluntary report and mentions the urgent problems. When there is damage to the environment, the community and local authorities will report to the parties concerned. 6.2.3. Environmental quality monitoring Environmental monitoring program is carried out in 3 phases of the project: pre-construction phase (background environment); construction phase (three years); operational phase (1 year after the project firstly comes into operation). In the preparatory phase of construction, the consulting unit should be in collaboration with the Meteorological Station of Mid-Central Region to perform monitoring, sampling environmental monitoring of air quality, surface water, soil and aqua-organisms to assess the current state of environmental components in the project area. During the construction phase, the impacts on the natural environment and society of the construction of the works items taking place mainly in this period. Therefore, the project owner will implement the monitoring programs such as the table below. During the operational phase, the majority of the negative impacts disappear, and the positive impacts appear. The negative impacts gradually become more stable, therefore some work items are not required to take the environmental monitoring. The table below is an overview of the environmental monitoring program of the project in the construction phase and operational phase of the project: Table 6-3: Contents of environmental monitoring during the project phases Pre-construction Construction No. Items Operational phase phase Phase I Environmental monitoring of air and noise/vibration 1.

Monitoring of the implementation of the dredging material management plan (DMMP) To ensure that the activities of dredging, transport and disposal will not cause negative impacts on residents and the local environment, a guide for preparation and monitor of the dredging management plan is presented in the box below. Accordingly, the detailed design will include a basic test program and develop DMMP reflecting the instructions below in a proper manner.  Guides of preparation and management of DMMP The main social and environmental issues related to the dredged materials contaminated include: (a) Pollution in the process of transporting the dredged material from the dredging area to the dump area; (b) The increase in turbidity and water pollution in the lake and channels in the dredging process (c) generation of bad smell and other disturbance to the Consultant: IAC Vietnam Page 172 Updated EMP Report – The Adjustment Works under the Danang SCDP residents; (d) The dredged material contaminated infrastructure may be misused for families and public infrastructure. To assist in the preparation of DMMP by the activities carried out in the urban area or the current water bodies can also be used by other using objects, the following issues should be considered: - Sediment quality evaluation: this evaluation to determine whether the sediments contain a large amount of hazardous materials to the environment as heavy metals and other toxins or not. If these substances are found higher than the allowed threshold in the national environmental standards, a special disposal plan will be prepared with a monitoring plan. Disposal plan will also set up for the program to ensure the local communities not using dredged material for building houses or gardens. The sludge and bottom sediments will be sampled for analysis of major pollution indicators. The sampling and analysis must conform to the governmental regulations meanwhile the sampling locations depend on the risk level for each specific location. - Identify the land available for disposal of dredged material. The plan should also identify suitable dump sites for dredged material in line with the risk level associated with them. The public land zones, land for construction of rural roads, public buildings, private land ... can be used with the consent of the affected households. If the risk level from dredged sludge is high, this sludge must be dumped at Nghi Phu landfill which is operating. - Prepare for the plan of dredging and transport of dredged material//sludge. The process of dredging and sludge transportation plan should outline: (a) the dredging methods (using pipelines, pumping before digging ...) and dump sludge at the disposal area or onto the trucks or to a temporary disposal area. If the trucks are used, the way of transport from the dredging site to the disposal area should be specified, (b) the time of dredging, (c) the transport vehicles and the proposed measures to reduce the leakage of dredged material from the means of transport, (d) the contractor's responsibility is to clean up the roads and implement remedial measures results if necessary, and (e) communication plan to the neighboring communities including contacting phone number in case of complaints - Temporary storage of unpolluted sludge and sediment so the dredged material will be first in slush state with soil particles suspended in 24-48 hours, all water comes out of the sludge temporary storage yard will be directed into the sewers and discharged back into the channels/lakes. For highly contaminated sites, the smelling organic substances, dredged material must be transported in sealed containers out of the construction site as quickly as possible. For less contaminated bottom sludge, organic substances, dredged sludge will be transported to the properly designed storage areas in terms of location and size. A monitoring program for disposal of contaminated dredged material will also be prepared. - Identify areas/major objects (such as business establishments, schools, public services, etc.) which are sensitive to dredging operations and transport. DMDP will make a general analysis of business operations affected locally, access to water and affected traffic situation (caused by dredging), and provide a plan to mitigate/compensate for the consequences of the obstructions. The plan must also include all possible measures to minimize the impacts on traffic, the local water supply. - Identify the main objects using other water sources. Dredged lakes can be used by other objects, so dredging activities can affect them. It is necessary to prepare a monitoring plan of water quality with specific stations and possible parameters to monitor potential impacts on users. Priority is monitoring sensitive areas with the change of water quality (high suspended solids, low pH, high BOD and COD, high salt ...) especially in the places where water is used for domestic and agricultural activities. In areas where Consultant: IAC Vietnam Page 173 Updated EMP Report – The Adjustment Works under the Danang SCDP dredging activities can cause negative impacts on water users, the project owner must inform and consult the water users and implement actions to address their concerns including implementation of water quality monitoring in DMMP. 6.3.

CAPACITY STRENGTHENING PROGRAM The capacity strengthening program for additional items of SCDP project is a part of the capacity strengthening program of SCDP project. The actual implementation of the projects shows that the coordination of environmental management has not gained the most effectiveness by some of the following reasons: There is lack of a unified coordination mechanism, an establishment as of the beginning between the PMU and the relevant authorities, especially the local government of wards/ communes where the project is carried out. Local officials are not familiar with the loan project process, but they often follow habits of domestic projects, the participation is limited. Consultant: IAC Vietnam Page 178 Updated EMP Report – The Adjustment Works under the Danang SCDP The community has not been clearly aware of their rights and responsibilities for environmental protection or they understand rights, but lack of a mechanism, a specific tool for feedback. The relevant authorities are often not ready to coordinate the project. There are some agencies which have sent specialized staff to monitor and coordinate the project, but it is only a temporary nature. The assigned staff also cannot grasp the methods of coordination and deployment as well as the procedures necessary for the exchange, connection to the PMU. To overcome these problems, the analysis and evaluation of the capacity, the demand of the relevant divisions in the environmental management system, analysis of the actual demand of the project is necessary.
