3 Summary of existing natural and socio-economic conditions

3.1 Natural condition at project areasDanang has typically tropical monsoon climate, the annually average temperature isabove 25°C and annual average humidity is 82%. There are two obvious seasons inDanang including rainy season from August to December and dry season from January toJuly. Tidal regime of Danang sea is diurnal tide and irregtular half-diurnal tide.a. Air quialityv at project areasThe projects areas are mainly affected by high concentration of suspended particulates,the tested TSP values range from 5.1 to 49.2 mg/m3. These are many times higher thanthat of Vietnamese standards, especially at inner city roads such as Ong Ich Khiem roadand Nguyen Hoang road. Noise in residential and suburban areas are still low, except attraffic roads, tested noise varies ftrom 52 to 84 DBA. Other emissions such as NO,, So-,CO... are still below standards. However, residents at low income areas and along lPhuLoc river has been affected by odor, in which the most affected areas are those close toexisting city outlet such as at Dung Sy Thanh Khe bridge or at outlet near Clinic Centreat Tran Cao Van road.b. Suirface water qualityImproving the river environment of Phu Loc River is one of the key priority itemas inorder to improve the city life and is invested in the first period of the project.Phu Loc River is one of the main and big drainage channels in the city. It is origiMatedfrom the drainage channel connecting with West Lake and flows to Da Nang Bav throU-gestuary at Nguyen Tat Thanh Road, Thanh Khe Dong ward. The rehabilitated leng,th isabout 2 kilometers and the width of river is from 50 to 80 meters.T'he enivironment in Phu Loc River has been polluted not only due to domestic wastewater from the inhabitants along the river bands, but also due to the rubbish thrown bvth-e groups of the inhlabitants. This is a significant concern for a long time and has greataffection on the groups of the inhabitants along the river bank. According to testillnresults, the pollutant contents of Phu Loc river are highest at the middle and lowest at theoutlet. Waste water from Phu Loc river has been discharged into Danang bay alldcontaminated coastal water quality. The figure 4-1 presents water quality of I'huI I.ocriver.

Ground water from confined aquifer in project areas has good quality and could be usedfor domestic purpose, tested parameters are below standards. Physiochemical parameter-sof ground water from water table are lower than that of standard, however, colitorm aredetected from almost of testing samples (3/4 samples).

3.2 Socio-economic condition

Till the late year of 2005, the entire population of Da nang city is estimated about790,191 people, of which the total male is 384,806 people and the total female is 405.385people. The allocation of the inhabitants is concentrated on Thanh Khe district and FliaChau district. The rate of population growth in the citv in 2005 is 2.35%. of whichi therate of the natural population growth is approximately I . 18%.

According to data of socio-economic surveys in the project area, workers are 25.5%.small businesses are 26.4% and 21.2% are working for government office. The otherearns their living by hunting aquatic and agriculture productions or undefinded jobs.Unemployment rate is 8.4%. Before out of work, jobs of interviwees were nuLcldiversified. 3 0.8 % of which worked in services and 15.4% were staffs.

Based on those figures. 23.3% of the total households surveyed is considered poorhousehold according to the standard of Ministry of Labor, Invalids and Social Affair.

People will continuLe tolive in bad infrastructure conditions and unhealtlhy environment. The Phu Loc riverenvironment has been polluted over years, so it is a big concern of local authorities andciinhabitants. If this river is not improved and continues to receive untreated wastewater,pollution situation will become more serious, the local residents' health as well as citybeautifiul looking would be influenced. Although investmenits were made under Drainageand Sanitation Project in the sewage and drainage system. it still could not meet tlhe citydevelopment speed because of fund limit. Particularly, there is almost no sewage systellmin niewly established districts. Main comnunication routes to be constructed will not onlymeet the increasing traffic demand but also lhelp create good conditions for economic andtourism development in the project area.

3.2 Upgrading alternatives of tertiary infrastructure for LIAsThe alternatives for upgrading road engineering and socio-economic infrastructure hlavebeen consulted for the second time with the community in June, 2007. AtYcr theconsultation, the community at eaclh l,lA has choseni priorities ftor upgradin- andlpreliminary alternative for road system, which are presented below.

3.3 Alternatives of Phu loc river rehabilitation

a. Alternative of embankment anid access road

In this phase, the Phu Loc river will be rehabilitated based on the existing alignmnenit. Tosolve the problem of sand deposit at the river oLitlet, 2 retaining walls with 50m lengtlh andan open angle of 200 will be constructed in order to extricate the water current and to reducethe energy of the seawaves that hit the abutment (figure 3-4). Proposed alternatives arepresented in table 3-4.

Alternative aniaIVsis anid selection

Option 1

* Advantage: nice section, simple construction maethod, quick conlstructioln lominvestmnent cost.

* Disadvantage: high land acquisition due to large width of cross section (B-35m).

Option 2

Social aal(d Envi'ronmental Development Joint Stock Col,11pavql (SLCO) )-S

Danang PrJorjI' InJi astruclure Investment Project E.] repol i I'fltise la

* Advantage: lower land acquisition due to less width (B = 30m), structure is more stable.

* Disadvantage: complicated construction method, long time, piling would affect theexisting structure, high investment cost.

Of the two proposed options, option 2 has larger quantity of construction work and needshigher number of construction equipment because it is necessary to use specialized machinesuch as R.C pile drivers, heavy crane etc. during the construction. Additionally, the volLilleof excavation and embankment in option 2 is higher. Thus, the environmental impacts inoption 2 are predicted to be larger than in option 1. In social impact aspect, option Iacquires more land and the number of affected people is higher than thiose of optioll 2.Regarding construction method, construction of foundation in option I does not requiredeep excavation, while deep piling is required in option 2. The river bank usually has weekgeo-structure and low strength. Moreover, there are some large works such as the Colleg,eof Gymnastics, 29/3 Textile Company, Commercial College... that are close to the riverbank. Therefore, constructing embankment with deep foundation would afTect the struCtureof these works and houses, leading to the assets damage. Having taken into considerationengineering aspect, social and environmental impacts. construction cost as well as satetyduring construction, option 1 was selected.

b. 41ternative of dtrainage aitd wastewater collectiont

The drainage system in this area is still a combined system as most of the sewers connlectedto th-e Phu Loc river are collecting both rainv water and wasterwater. For eachi outlet. Lmaithole will be constructed to separate wastewater into interceptor sewers, which conveyto Phu Loc WWTP for treatment, whereas storm water will be separated and discharged inltothe river.Along two sides of pavement, sewers to collect wastewater will be installed at the pavcemielntnext to collecting sewer and intercQptor sewer lines will also be constructed. Two methodswere proposed for collecting storm water and wastewater:

Location of sewer lines installatiion

Option I

- Interceptor sewers are installed at the pavement next to houses to collectwastewater on the way and from the overflows of the existing sewer outletsdischarging into the river. These sewers are installed parallel with and near thesewers that collect storm water along road.

Option 2

- All sewers to collect waste,vater are installed at the pavement next to thechainels: sewers to collect surface rainy water are installed at the pavement next tohouses. Along the line, some overflows will be put to let rainy water tlow into theriver; wastewater, whereas, is separated into interceptor sewers to conduct to thetreatment station.

Comparing these two methods, method 1 is more comfortable for collection.EHowever, as the depth of interceptor sewer lines will be from 2.4 - Sm, they arefrom 0.6-0.8m deeper then the level ot rainy water sewer. According to prescentconstruction actLality, it will cause subsidence and cracks for surrounding houses.leading to costly construction cost. In method 2, construction and embaLinkillnworks can be done together near the river, the construction cost is therefore savedas the surrounding houses will not be affected. Therefore, method 2 is chosen.

Alternzative of drain age, wastewater collection and treatment

- In the newlv bitilt residential aireca in the north of the two sides of Phai Loc rNier,wastewater will be collected from common sewer system by newly installecoverflows into the interceptor sewers located along the service road pavementnext to the channel and then conducted will be into the interceptor sewers oiNguyen Tat Thanh road. There are 4 outlets along the two sides, 2 for each.

- 0n the left side of the channel, residential areca of T`lanh Khe Tciv' ward alon,the twvo sicdes of the channel and from Dung Sv Thanh Khe road to bricdg,,e No 1,concrete common sewer system is constructed to collect rainy water andwastewater on the road, 2 outlets are located to separate rainy water.Wastewater is collected into the interceptor sewer system and then conveyedthrough the river to the riglht side of the chamnel into pumping station no. 2, thlellpumped into the Phu Loc treatment plant, which is about 120m from thiepuLMping station.

- On the right side of the chctnnel from the Thianh Khe 5 LlIA to Dung Si' Than!hKSie roadi, rainy water collecting sewer on the road and interceptor- sewersystems are installed to collect wastewater from overflows. Collectedlwastewater from the LIA sewers, from residential area of Xuan Ha ward fromXuani Ha - Lien Phuong sewer Bx1-l - 5x2m, from the railway station througllTran Cao Van BxI-I - 1.5 and letting out sewers on Dung Sy Thanh Khe roadwill be led into pumping stationi no. 1, which is expected to be raised near Dung1,Sv Thanh Khe road.

Atpresent, the area is rice field with 55 households and some part of land is open area of'475 store. The elevation of the area varies from +1.60 (ponds, lakes) up to +8.5(). Thleaccess road is a plaimed road with section 5.0m + 10.5m + 5.0m connecting to LienlChieu -- Thuan Phuoc road. This resettlement site is for affected families from LienChieu district and some ai'fected families from Thanh Khe district. Alternatives forinfrastructure in LIAs are as follows:

- Construction of a transportation route with cross section of 5m+10.5m+5m of alength of 460m; a road of cross section of 4m+7.5m+4m and 240m lengtKl- anldanother road of cross section of 3m+5.5m+3m and 1,150mn lengtlh. The roadswill have hot bitumen paved surface witlh standing loading capacity of H13,cement-tiled pavement,

- Resettlement plots with average area of 103.6 square meters, the smallest of 96square meters and the biggest of 200 square meters. There are 1.5-meter openstrips of land behind associated plots reserved for drainage system to collectdomestic wastewater, discharging to the combined sewer under the sidewalks.

- Alternative of water supply: domestic Nvater demand is 1501/ capita-day. Waterwill be supplied from existing water supply pipeline +200mm of North-WNest 2pipeline. The trunk water pipeline would be ductile iron pipe ( l50mn.llHousehold connections will be made available from service networks of D6()'IIDPE and DI10 uPVC pipes. Fire hydrants with service radius ot' 150iS x\1illalso be installed.

- Alternative of domestic wastewater collection : grey and fiush xvastewater fiomlhouseholds will be collected by a common brick culvert covered by concreteslabs of B=350mm constructed along the open strip of land, then dischar-gedinto the collection manholes located at the road.

- Alternative of storm water : the drainage system of the area is in fc,Ct acombined system, which will collect both storm water and domestic wastewaterfrom households. All the drainage systems will discharge to Ho Tung Mausewer in the new North West residential area. From here, wastewater will bedischarged to North West area belonging to catchment of Phu Loc WWTP.Wastewater will be separated downstream and conducted to the existing PhuLoc WWTP for treatment.

b. Hoa Quy resettlemenit area

- This is an area of 5.96ha in the north ofl southern ring road of the city and DanangUniversity Campus, next to the planned Dong Tra residential area.

of B=350mm constructed along the open strip of land, then discharged into the

collection manholes located at the road.

- Aternative of storm water: drainage system of the area is actually a combinedl

system, which will collect both storm water and domestic wastewater fromi

households. As this area belongs to the Phu Loc river catchment, all stormwater

drains then flow towards the Phu Loc river, while wastewater will be separated and

conducted to the Phu Loc WWTP tor treatment.

4 EXISTING NATURAL AND SOCIO-ECONONIIC CONDITION

In phase la, project activities are scattered witlhin inner Danang city, inCludinig LIAs il

Hoa Khe, Thanh Khe Tay, Nam Duong and Hai Chau 2 wards, resettlement areas iIIHoa Minh, Hoa Quy, Thanh Khe Tay and Phu Loc river. Sampling location of baselineenvironmental survey in project areas are presented in figure 4-1.

4.1 Natural condition

4.1.1 Topography and soil condition

Hai Chau and Thanh Khe District are almost plain without mountains and haverelatively flat terrain. The average elevation of Thanh Khe District is 3m and E lai ChauDistrict is 2.5m. The terrain of Ngu Hanh- Son District is only flat in the South, in theNorth it is high and low unevenly. There is a high mountain called Ngu Hanh Son withalternate mountains and caves below (the average elevation is I lm). Half of LienlChieu District area is occupied by forest. High mountain concentrates in the Northwi estwhile the remaining area is relatively flat (the average elevation is 8m).

Danang lies in a coastal area with geo-structure comprising sea sedimenit and thePleitoscene strata formed by rivers. Low hill area and high mountain r angesintermingle with alluvium delta and have structure of Paleozoic sediment rangeinter-mingled by medieval Mio-Pliocence sediment layer. Rock layers lie within thedepth of lOm to 15m.

4.1.2 Climate conditionDanang has typically tropical monsoon climate. The temperature is high and rarelyflictuant. The regime of sunshine. rain and humidity is various. The annually averagetemperature is above 25 C and average humidity is 82%. Danang's climate isintegrated and affected by Northern and Southern tropical climate as the predominiiaint.There are two obvious seasons in Danang includinig rainy season f'rom August toDecember and dry season from January to July. Occasionally, there is a cold spell of'winter but it does neither last long nor cause serious coldness. Rainstorm often leads toflooding. There are 1 - 8 storms per year. The rainfall in rainy season accounts oibr 7()- 80%o the total annual rainfall. In summer there is little rain and high temperature thulsin somlle river outlets there is a high level of salinity. The climate features of Dal-Ln110are presented in Table I - Annex A.

4.1.3 Tide reoimeTidal regime of Danang sea consists of diurnal tide and irregular half-diurnal tidewhich means that in half a day, there is one flow and one ebb but the power of and thetime the flow and ebb last are much different. There are in average 3 days of diurnialtide per month (8 days at maximum and 1 day at minimum). Affected by suchI a tideregimiie, the hydraulic regime of the canals and sewers in the City is relativelycomplicated. During floods, the sewers and canals receive both storm vwater andiwastewater from residential areas. Moreover, they are also affected by raising, wNaLterand wave during flood tide. The highest average flood tide level is 120cimi and thielowest one is 80cm. Table 2 - Annex A presents monthly tide level.

The survey results show that, air environment at project areas has been polluted nmainlvby dust as the TSP content were 19 - 65 times higher than the standard (figure 4-2). Aparticular case was recorded at Ong Ich Khiem road where the TSP content was 160times higher than the alowable limit, which was caused by high traffic density ot"Lup to1,300 - 2,200 motorbikes/ h and 50 - 150 cars/ h. The LIAs and suburbs were notaffected by noise, while the noise level measursed at inner city areas such as at OnbIch Khiem and Nguyen Hoang roads were relatively high and exceeded standard.Content of N02, S02, CO emissions were below standard. The project areas wer-e notpolluted by lead particulate and gas.

The above results are quite corresponding to the results of socio-economic SuIVeY andLthe public consultations conducted at projects areas. As the survey's resLult, airenvironment at project areas has been polluted mainly by offensive odor (53.8%) anddust (25.5%), interviewees also reported on1 high noise but with low magnitude (4.7%).(Source.: r eport on social assessment - SECO). The participants at public consultationlsalso reported on offensive ordor and high dust. The most severely affected residentialareas by bad odor from the Phu Loc river are the ones located along the river.particularly the ones close to the city's drainage outlets at the bridge on DuLng Sy

4.1.5 Existing water environment at project areas

4.1.5.1 Exisiting condition of surface waterSurface water at project areas include a)Water environment of the Phu Loc river; andb) Surface water at Hoa Quy resettlement area.

a. Water environmental of Phu Loc River

Improving the environment of Phu Loc River is one of the top priorities in order toimprove the city environment and will be invested in phase la of the project.

The Ph-u Loc River is one of the main and big drainage channels in the city. Itoriginates from the drainage channel connecting with West Lake and flows to DaNang Bay tlhrough the estuary at Nguyen Tat Thanh Road, Thanh Khe Dong ward. Theriver section to be reh-abilitated has a length of about 1,83 krn and the width from 50 to80 m. At present, most of two river banks are earth-banks and have had no access road:yet, except for some routes crossing the residential area or the section near the riveroutlet. There are many places where residents build houses and auxiliary works besidetlhe river. The flora growing along the river bank are very poor, mainly wild gr-ass, wildtree, wvater-taro, flamboyant, malabar almond tree. etc... At some parts of the banksthat cross tlhe residential area, the earth band is extended with silt and used by theresidents to plant sweet potato, vegetable, papaya, banana tree and nipa, etc... The areaof river bank near the sea is the place for boat parking of the fishers living along botlbanks. The Phu Loc river outlet is usually extenided witlh sand deposit whichl blocks theflow, even covers most of the outlet. Therefore, the city has to dredge, collect ailcdispose the sand away every several years. As the river has been receiving wastewaterfor years, it is severely polluted and there are virtually no valuable aquatic organismsin the river.

The environment in the Phu Loc River has been polluted not only due to domesticwastewater from the inhabitants along the river, but also due to the rubbish thrown tothe water. This is a significant concern for a long time and has great impacts on thleinhabitants living there. According to the observation, the color of river water is deepiblack or moss-green at the places where the river pass crowded residential areas. Thlerotten smell is very awfiul, especially at the main city's drainage outlets wherewastewater is discharged into the river (the lower section next to the Phu Loc Bridgein Tran Cao Van road, at the drainage outlet near the health centre). The river-bedl herehas been consolidated seriously. There are some sections where the river-bed narrowednearly half of the width, the depth of water level is only about 0.5 meter. in the past.waterwaste from the factory 2 of the 29/3 Textile Company was discharged directlv tothe Phu Loc River which caused pollution of this river section. Since late 2006. thefactory built and operated its own waterwaste treatment plant (WWTP) and asrequested by Danang Department of Natural Resources and Environment (DONRE),the effluent from WWTP was conducted to the city drainage system, so the pollutionsituation was improved. However, the WWTP has just been operated for not a lonutime. tlherefore the effluent's quality neqd to be well supervised by the city.

From 2002 to now, the quality of the river water has been continuously monitoredwithin the framework of the Environment Management Plan under the SanitationProject of Da Nang city. The value of BOD. COD usually does not meet the surfacewater standard in recent years and the pollution level in rainy season tends to be moreserious than in dry season.

To assess and compare water quality along the Phu Loc river within the framework ofthe PIIP, samples have been taken at 4 stations: the river's starting point (close to PlhuLoc WWTP), downstream of the city's drainage outlet near 29/3 Textile companiy.near Phu Loc outlet and Danang Bay around the outlet. The samples were also takeni 4times: twice at flood tide and twice at ebb tide. Average analysis results of waterquality are presented in Table 4 - Annex A.

The result of sample analysis shows that the river is seriously polluted, the contents olBOD5 , COD, SS, NH4 + were much higher than the permissible level. The mostseverely polluted place was at downstream of the city's drainage outlet near the 29/3Textile Company. Although the Phu Loc oulet area is less polluted than the streallmflow since it is diluted partly by the sea water, the measured parameters were stillhigher than standard. Wastewater discharged to the river has been very much pollutilngsea wvater around the estuary, especially during the ebb tide as the measuLredparameters were much higher than standard.West Lake: located in Trung Nghia residential area, which is a lowland receivingstormwater fromi Hoa Phat residential areas. In the detailed planning, West Lake is astormwater regulation lake and creates landscape for the area. Currently, Hoa Phat.Nguyen Huy Tuong and Trung Nghia residential areas are being constructed to havetheir drainage systems discharging into the lake, which is connected to Phu Loc Riverby an irrigation channel.

b. Hoa Quy resettlement area:

This area is a paddy fields within Dannang Urban Planning Areas. At present, it is anopen area with some ponds formed by storm water stagnated in sunken areas. Inaccordance with the test result, the surface water there is of quite good quality asalmost all the analyzed parameters are below the standard. It is so because ther-e areonly few people living along Luu Quang vu road and the surface water there therefol-e

Danc7ng Priority Infrastructire Investment Project EA report - Phase Iai

has not been polluted by wastewater. Testing results of surface water quality at HioaQuy is presented in Table S - Annex A.

4.1.5.2 Existing ground water qualityIn recent years, due to big population growth and limited capacity of water supply, thenumber of families using groundwater from drilled wells is increasing considerably.According to surveys, the city's groundwater reserve is about 100 million m3 , 30% ofwhich has been exploited and brought in use.

The groundwater quality at projects areas has been surveyed and analyzed within theframework of the PIIP and the testing results are presented in Table 6 - Annex A.

Survey results show that quality of artesian water at project area is rather good (samplefrom Xuan Hoa and Chau Thanh) as all measured parameters were lower thanpermissible levels. However, in the 2 nd public consultation, the participants from HoaKhe reported that groundwater at the area near Da Nang airport is contaminated bydioxide and could not be used for drinking and domestic purposes. Physiochemicilparameters of shallow well water were still lower than standard, but most of them werecontaminated by bacteria. Pollution sources might be the run-off water or wastewaterthat penetrated into the ground since these residential areas are densely populated andagc-old ones. Groundwater from Thanh Khe Tay (sample NN5) was saline since it isvery close to Danang Bay. In general, shallow water at project areas has beencontaminated by bacteria, so it is unsafe to use for domestic purposes. Flowever.according to socio-economic survey, the number of hlouseholds using water tromdrilled/ shallow wells is relatively high. Specifically, the rate in Hoa Khe ward is 35%of interviewees, while it is 100%, 43,3%, 100% va 16,7% in Hoa Quy. Nam Duong.Than-h Khe Dong and Thanh Khe Tay wards respectively. Using contaminated waterfor long time might affect community health. Consulted people also reported oncontamination in groundwater at areas close to the Phu Loc river.

4.1.6 Fauna and flora condition, natural habitat

As the project areas mainly belong to the inner city, except Boa Quy resettlement area asa suburb, tlora and fauna in these areas are veiy poor. There are no valuable species, floraare mainly wild grass, some areas are small paddy or cultivated fields. Besides, there arecoconut-palms, bananas, almond trees, flamboyants... in some residential areas along thePhu Loc river. In urban areas, main flora are found in small parks and along the streets.According to the DONRE, presently, the city has about 20,000 plants whichi create260,000 m2 green spaces or a coverage rate of 0.35 mr2 per capita in equivalent, muclless than VN regulation of 5 m2 per capita (applied for city over 200,000 residents).

Iloa Quy resettlement area is part of the City's new residential area. This is a flat areawith gr-aveyard covered by wild grass and scarteredly planted casuarinas.

Sea ecological resources:As from Department of Fishery, Agriculture and Forest, there are no aquatic resoLurces oraquaculture around the Phu Loc river outlet.Regarding natural habitat, according to the study (( Survey, study coral and relatedecosystem for area from Hon Chao to the south of Hai Van mountain pass and Son 'Erapelnillsula >>, there are coral reefs inshore Da Nang beach, extending from tide area towhere the depth is less than 12m. The coral reefs in good condition gather at I-[on Sup,Bai But, Bai Nom, Huc Lo, Vung Da, south of Son Tra peninsula.Regarding regional organisms, the study recorded 221 species of plankton, whichl werefound with high density in the middle of Da Nang Bay and northwest of Son Trapeninsula. For zooplankton, there are 162 species, whiclh concentrate with higher densitvin the south of Son Tra peninsula than other areas. Species of larvae inshore Da Nangcoast. particularly crustacean larvae are rather diverse and plentiful. In genieral. numberof species and density of larvae sources in west of the Bay and southl of SonI Tlrapeninsula are higher than that in remain areas.Nutrition contenits in water inshore Da Nang coast are below standards, so organicre-sources in this area have not been affected by poluttion. However, high content of oiland suspended solid would affect these coral reefs, especially in the north and SOUth1 ofSoni Tra peninsula.The study also proposed areas for proper exploiting of ecological and organic resourcesinshore Danang coast. However, as it is relatively far from the Phu Loc outlet to theproposed areas as it is about 6km to Son Tra peninsula and 9km to south of' Hal 'Vanmountain pass (figure 4-5), the project activites in the Phu Loc river would not affectthese areas.

4.2.2 Culture and education

Da Nang is not only the centre of economics, but also plays a role as a centre ofedtucation and training in the Mid-South region, especially high level college aLnd

university education. In the last 5 years., the citv took care about the investment for theeducation and training career. The budget for education accounts for approxillmatelN56%/o of the total expenditure for social career. If the budget for the education andtraining mission was VND 94.6 billion in 2000. the investment level for this task in2005 was 2.5 times higher as of VND 236.2 billion. Up to late 2005. Da Nang had 11 l0elemlentary schools with 1,435 classes, 2213 teachers and 33,822 pupils. Regardilk,universities, colleges and vocational schools, there were 22 schools wvitlh 2.306teachers and 13 1,840 students, of which 1.283 were post-graduate students.

At present, Da Nang has 3 cultural houses, 3 libraries, 3 museums and 11 historicaland cultural spots which are ranked. TFhe rate of budget for cultural and socialactivities increases year by year. Special attention have been paid to the issue ofcultural information in poor and rural areas in order to shorten the cultural gapbetween the urban and suburban areas.

4.2.3 Public health and safetyAt present, in the city, there are totally 70 heath care centers with 3,270 sick-beds, ofwhiclh there are 4 central hospitals with 695 sick-beds, 16 local hospitals. 47 lhealthcenters and midwife centers at district level, 3 health centers, private health services aswell as the development of 225 sick-beds in 4 private hospitals. The health careservice in the city involves in total 3,843 staffs with the rate of 13.1 doctors per lo0,0()citizens. All districts in the city have their own health care center.In the project area, 21.7% of interviewed housholds get chronic disease. includingrespiration diseases as sinusitis, lung disease; disease related to digestion as gastric.cardiovascular diseases together with rheumatism. Many people also said about boniediseases, mainly related to spinal column (Spinal column, vertebra degeneracy etc.).Patients of chronic diseases are mainly elder (41.7%). It is worth attentioni that amiollngintervewees in phase la, 52.4% believed that their illness related to envirornmentalcondition, in which 46.2% said their illlness related to environment and water resouLrcespollution while 28.2% said it due to air pollution.

4.2.4 Occupation and incomeUp to December 315', 2005, the labor resource of the city is 487,096 people, ot whiclthie labor force that is in employment is 367,761 people, and the unemploymenit rate is5.05%. Regarding the labor allocation in sectors, the labor force in the service industrVsuch as commerce, hotel, restaurant, transportation, infornmation and common LnicaLtioll.etc... accounts for 42.46% of total labor working in the economic sectors. Industi-' andconstruction also involve considerable labor resources as of 38.15%'o. This figul-e in tileagriculture, forestry and aquiculture is 19.39%.According to socio-economic surveys in the project area, workers account for 25.5%oof the Labor force, wlhile small businesses involve 26.4% and other 2 1.2%/o are worlkinfor government offices. The other earn their living by hunting aquatic and aFricultureprocductions or undefined jobs. Unemployment rate is estimated at 8.4%/6. Befor-egetting unemployed, jobs of interviewees were much diversified. Amogllunemployees, 30.8% worked in services and 15.4% wvere government staffs.The income of the residents also has gradually increased following the economllicgrowth. The average income per capita in 2004 was VND 635,000/ month or is twiceas much as in 1999 (VND 317,200 / person/ month). Although the city has no povertyhouselholds, poor households still exist. Based on the national poverty line (tlhe averageincome per capita under VND 150,000 per month accordinig to Decision1143/2000/QD-BLDTBXH), the city has only 2,858 poor households in 2003 anld 733in 2004. Based on the specific conditions of the local socio-economic developmiienlt, ill2003, the city's authority established its specific poverty line that clasifies househo0ldsas poor if their income per capita is under VND 300,000 per month for urban areas anduLnder VND 200.000 per month for suburban areas.Based on the social-economic survey for project areas and existing living conlditioni ofthe city, the investment report namely "Construction of priority infrastructure for L.Da

Nang" proposed to apply the level of income per capita of VND 400,000 per month aspoor standard for the project. According to the figtires of socio-economic surveysconducted in June and July 2006 for project areas, monthly average incomiie ofhouseholds is estimated at VND 2.2 million, of which for some houselholds this f-HLIgueis onlv VND 120,000. Based on those figures, for phase la, 15.1% of' the totalsurveyed households is considered poor according to the poor standard of Ministr-y of'Labor, Invalids and Social Affair (MOLISA), whereas it is 20.8% based on thespecific standard of Da Nang city, and 34% based on the standard set by the project asabove. The average income per capita is about VND 472,000 per month. Incomparison with some cities, this level is relatively low. The project investment willsurely help improve environmental condition and create job and income opportullitiesfor the inhabitants.

5.1 Positive impactsThe pro ject implementation will bring positive effects to people living in project areas aswell as the city.a. SuppIv clecin water for residents: Most oflthe existing shallow water in project areas

has been polluted by bacteria, thus unsafe for uIse for drinking and domestic purposes.The project upon completion will support in supplying water for daily domesticpurposes for communities, which helps in long term improve public health. Based onthe existing water supply in project areas, the beneficiaries in Hoa Khe and ChauThanlh LIAs would outnumber those in the other areas.

b. Increase drainage ccapaciv, reduce inundation. by installing new drains and dredgingexisting sewers, drainage capacity of the system will be significantly improved,particularly in areas that are sunken or have not any drainage system yet as well as inareas along the Phu Loc river.

c. Solve polliution fromn wastewater. field trips and public consultations showed that.pollution from wastewater was common in most of the project areas, especially aloii-the Phu Loc river. During operation phase, wastewater from the PhuL Loc river'scatchment will be collected and treated in the WWTP, which helps eliminate thleproblem of polluting wastewater and improve public health in pro'ject areas.

di. Improve environment of the Phu Loc river: the river has been polluted by wastewaterfor years. which in turn influenced the water quality of Danang Bay around its outlet.Al'ter being rehabilitated, the river water quality would be significantly improved,wlich help recover the aquatic ecosystem there. During operation, the PhIU Loc riverwould create a beautifill landscape for Danang city if it is well managed.

e. Increase landutse value: road and alleys as upgraded and widened will facilitate localtraffic, contributing to economic development and living condition improvemenlt.These changes would indirectly increase landuse value in project areas.

a. Dutst: generated during demolishment and debris transportation from site to disposalarea. It is predicted that amount of dust generated in Thanh Khe Tay + Xuani Hoia ALIA, Thanh Khe Tay and Hoa Minh resettlement areas will be relatively higlh due tolarge number of demolished works and their concentration at the site. The amoullt ofdust generated during the Phu Loc river rehabilitation is only at mediumLL levelbecause the demolished works are scattered along the river.

b. Air emiiissions: emitted from demolishing and transporting equipment, bulldozers.Load of air emission in Thanh Khe Tay and Hoa Minh resettlement areas and TlanlhKhe t + Xuan Hloa A LIAs would be higher than that in remaining areas. Load of airemission generated in Phu Loc area is small because demolished works are scatteredalong the river. Besides, there is a rather insignificant air emission from demllolishiedsewers or septic tanks.

c. Noise tand ^vibr-ation: generated during demolishing and froom equipment operating atthe site. However, because only a feW number of equipment are used in this phase.mainly bulldozers and excavators, and most of demolition will be carried outmanually by displaced people, thus this pollution source is negligible.

d. Wastew,ater canicd run-off water: During destructuring of underground works, it isnecessary to temporarily block the sewers. In case of raining, run-off water wvould bestucked and lead to partial flooding. Some amount of wastewater is generated byworkers and households around the site. H-Iowever, as the number of worlkers is smalland the destructured houses are scattered, the wastewater volume is predicted to besmall at individual sites.

e. Solicd wuastes: include mainly construction debris such as concrete, tiles. maortar...frIom broken buildings, chopped trees during site clearance, and small amount oldomestic solid waste generated by workers. The biggest volume of debris is predictedto come from Hoa Minh resettlement area, followed by those from Thanh Klie Tayresettlement area. Phu Loc river, Thanh Khe I + Xuan Hoa A, while the volulilescoming from the remaining LIAs are relatively small. Trees to be choped concentratemainly in the Phu Loc river area and Thanh Khe Tay resettlement area.

Pollution sources in Chau Thanh, Trung Tam, Thanh Khe 5 LlAs and Hoa Quwvresettlement area are predicted to be inconsiderable due to small number of dislocatedhouseholds and the fact that, these areas are scattered in the city and dur-atioll ofperformance is short (1-2 weeks).

Due to large number of dislocated households, pollution source in LIA Xuan Hoa andaccuLmlulative sources in LIA Thanh Khe 5 together with Phu Loc area are significant. Incase site clearance in LIA Thanh Khe 5 and Phu Loc area are carried out together, itwould cause accumulative impact within the site, particularly in areas close to the PIIuLoc river. Duration of these activities would be 1-3 months.

5.2.2 Affected subjects and extent of impact- Air environment at site clearance's areas would be impacted during the whole

performance. The largest impact will occur in Thanh Khe Tay. along the Phu Locriver and in Hoa Minh resettlement area with areas of some 39,230m2, 34,570m2 and20,600m2 respectively. In Thanh Khe 1 and Xuan lloa A LIA, impact willconcentrate mainly at Ha Huy Tap road. In the remaining, areas, impact will occurmainly within alleys.

- Water quality of the Phu Loc river would be affected by demolition of existing sewerand by wastewater from workers or households during drainage interTuption, howeverthis impact extent is negligible.

- Soil condition: would be impacted by construction debris -enerated durinig demolitionland cutting trees. The number of trees to be choped and amount of agriculture land tobe acquired in Hoa Minh anh1 along the Phu Loc river are relatively higlh. Tlhe plantand vegetational cover would be destroyed but in small amount.

Piroject affected people (PAPs) could be clasified into the following groups:- People wvith significant loses such as land or real estate to be acquired, losinig access

to property, losing income or living means. The number of such houselholds in ThanhKhe 1 + Xuan Hoa A is 378 and for the areas along the Phu Loc river the fig,ure is299;

- People less impacted by the project in terms of land acquisition, access to property butstill impacted in terms of instability, pollution, spirit, security, traffic convenietice:

- People whose business or small trading activities are temporarily interrupted, whloreare living mainly in LLAs and whose loses are related to land acquisition foI alley\ideninig. However, the number of these people is small.

- Local authority: their loses are of such kinds as losing agricultural land, spenldingmuch time to pursue local people, losing tax on properties or businesses that arestopped, land acquisition.

5.2.3 Impacts assessment

a. Inmptict to air environm?lenit, nioise and vibrationIn pre-conistruction period, the main impacts to air, noise and vibration include:- Duist. impact by dust in Thanh Khe 1 + Xuan Hoa A LIA, Thanh Khe Tay and I Hoa

N'tinh LIAs, Phu Loc river are medium while it is very light in other areas. In tlhisphase, generated dust would increase TSP in project areas and be higher thalLstandard. However, at the moment TSP content in these areas is from 19 (Tharhli Klhe5 LIA) to 39 times (Thanh Khe I LIA) higher than standard. In fact, as demolitioniwill be carried out mainly manually, it will therefore together with regulal- waterspraying could reduce dust pollution remarkably.

- .Air einission: this impact is caused mainly by transportation vehicles. The emissionisincluLde S02, NOx, CO..., whiclh occur at transportation routes such as Tran Cao Van;Dung Sy Thanh Khe, Nguyen Khuyen, Ha Huy Tap roads etc. during per-formilanicedurationi. Duration of demolition is pre5icted to last from I week to 3 monitlhs. Basedon the existing environmental baseline conditions, the air pollution contents at pro'ject

SOCl / Uln IFn0ij,oniecntl/ De velopment Joint, .Stock Comlipailny (SEC ')

D)onnl7g Priority Inifrastru(ctitre Investmient Project Environmenta7l clssessment Report - Phose 1a

areas in this phase are predicted still to be under standard. Offensive odor emitteddLurinig demolition of septic tank would affect workers and people living within thesite. However this will only be slight impacts as the PMU will contract with thetJRENCO to remove septage before demolishing, in addition this work will be carriedout only in a slhort time.

- Noise and vibration: As the destruction and movement of houses and structures atclearance sites involve mainly excavators, bulldozers and some manual work withmediuLm concentration only during the daytime as well as most of the structures arealready too old, the impacts are predicted to be inconsiderable;

b. Impact to water environmentIn pre-construction phase, the site clearance activities carried out in the areas along thePhu Loc river and in Thanrh Khe 5 LIA, the impacts to water environment are as follows:- Activities to stop and change the flow during the construction of drainage and seweer

systems can make the water stagnant or cause some overflow especially on rainy daysand cause pollution to the water environment and affect the residents' doimesticactivities by bad smell.

- Destruction of old sewer system and transport of construction waste will cause somieincrease in turbidity of surface water and deposition at the site. Prior to theconstruction, the implementation agency needs to coorperate witlh the URENCO tocheck if the solid waste blocking item1s at outlets and inlets are functionnilng properlyin order to reduce impacts to surface water.

- During site clearance, domestic wastewater fromii workers and households will bestuck and stagnant due to destruction of sewer system. However? as the waslerwateramount is small and will be collected to pump into the city's common drainagesystem, the impacts to environment will be insignificant.

c. Itmpacts to soil conditionSite clearance activities at the areas along the Phu Loc river and resettlement areas wouldcause destruction of surface ground and vegetational cover. I-However, these wastes willbe classified, debris will be transported to defined location, so this impact is slight.Trimming trees and site clearance could impact the soil and cause changes to the existingvegetational cover. The total amount of acquired agricultural land in Thanh Klihe 'rayresettlemzent and along the Phu Loc river is large. Neitherless, there are no valuablespecies in these areas except cultivated crops, frLuit trees in gardens or casuarina andshade trees, thus tlhis impact is slight.tl. Traffic obstacle:In this phase, as wastes will be temporarily stored on-site, they would narrow mzaini roadlsand cauLse traffic obstacle to people living in the project area. Transportation of materialand excavated soil will lead to increasing traffic density at main transporation roads suchLus Tran Cao Van/ Dung Sy Thanh Khe, Nguyen Khuyen, Ong Ich Khiem, Ha Huy Tapetc.. which are main roads of the city and have already high traffic density, for example.traffic density in Ong Ich Khiem road is 1300 - 2200 motobike/h and 50 - 50 car/hI.Thierefore, increasing number of vehicles at these roads might result in traffic jam if it isnot well organized.e. Impacts to socio-econiomic environn2ent- Acquisition of land, walls, fences and gates to expand boundaries of alleys and site

clearance will impact on property, land value and area. Local people will eitherexpress their agreement on sacrifying the land or property on land or react negatively.Thus, it is necessary to have a good plan,to solve this problem of impacted people.

- In some places of Danang city, households use their front house places to runi smallbusiness in kinds of shops, temporary markets on alleys. Upgrading of alleys wvill stopsuch kinds of business, cause their income lose. Therefore, it is sure that impactedbusiness households will react in a negative way, thus it is necessary to have goodpolicies to deal with the problem.

- Land acquisition along alleys will impact on water supply, electricity andcormnLnication as some electric poles can be moved.

- The above activities will for sure impact and cause some disorder to daily lil'e of'impacted households. Those households that are not sufficiently informed may havenegative reaction.

- Upgrading markets may have temporary impacts to business activities of householdsat temporary markets.

- Entertainment places of local people may be temporarily closed to be upgraded.- For those local authorities at areas where alleys are to be upgraded, it will be difficult

for them to provide information prior to site clearance to stabilise local residents'spirit, make them understand about the benefits the upgrading will bring. Theauthorities will be busy by being closely involved in security issues to mitih.atenegative impacts during the project implementation especially durilng laildacquisition.

- Complaints or claims for compensation or land price may be made by somilehouseholds and it is unavoidable in case they will not be willing to move, wvhiclh \Villimpact on the project progress; land prices variation will occuL during the projectcontruction phase, especially during operation phase wlhen the environmenit in tlleproject area is significantly improved.

- It may also be necessary to deploy management activities relating to land busillessand new construction of households at ugraded alleys.

- During expansion of alleys, demoslishment of houses, undergrounld works and onground works, traftic jam on transportation routes and at intersectionis vill beunavoidab]e during waste transportation.

- Reactions from local authroties, communities and households on pollutions suchI assolid wastes, wastewater, stormwater and noise, and dust may occur in this plhase otfthe project.

In summary, land acquisition or site clearance for upgrading or expanding alleys canmake socio-economic daily life, environment, security and traffic in the project areasdisordered for some time. The investment owner, local autlhorities and local peopletherefore need to closely cooperate in order to minimize negative impacts to thleenvironment and society.

The main pollution sources during upgrading infrastructul-e in LIAs are identii'iecd asfollow:- Dust, air emissions and noise: Activities such as upgradinig, expanding alley's and

roads, excavating for sewer intallation, transportinig wastes or material in and out, oroperating machines will all create air pollution and noise. Within alley area, due tonarTow space, construction method is -aiamly manual, thus this pollution source isrelatively small. However, attention should be paid because construction activities are

Danang Priority Infrastructure Investment Project Lnv ironn7entol Assessnmet IRepoli -- Plhse l/

carried out very closely to the residential area. For main roads, the amouLnt of this kindof pollution is larger, especially at Ha Huy Tap road in Thanh Khe I + Xuan Hoa ALIA (road width of 19.5m).

- Wastewater ancd r un-offj water: Upgrading and expanding alleys, installation of waterpipelines or drainage sewers related to demolishing sewers of houses. breaklimgmanholes would cause wastewater outflow onto the ground and its stagnation, and

bad smell for surrouding areas. Stagnant wastewater will create a habitat tor insects(mosquito) development which is a source of diseases such as malaria, petechial feverand offensive smell for local people. Domestic wastewater generated by workers onsite during constrcution, if not properly collected and controlled, would ti 22

negative impacts to environment and of community's life, especially in rainlycondition or long construction period.On the other hand, upgrading and expanding alleys are also related to demolishillgexisting drains, which prevents water flow. Therefore, storm water may becomzestagnant in flood areas during rainy season or if it is raining. In Danang, there was aheavv rain that can flood up to 1/2 m underwater within some hours.

- Solicd wastes: solid wastes generated during construction include (i) excavated soilduring site clearance, alley expansion, digging trenches for water pipeline and draillgesewers, digging for installing poles or electric lines and (ii) domestic solid waste fromlwxorkers. Thus, proper measures need to be taken to manage and transl'er these solidwastes shortly in order to clear the way and clean environment for the upgradedallevs.

b. Affected subjects

Subjects affected during upgrading infrastructure in LIAs are as follows:

- Air environnment in LIAs would be affected. However, as constructioll will take placein small areas and be performed manually and at small scale, the impacts arerelatively small and last for short time, about 1-2 weeks at each alley. Airenvironment at main transporation routes inside and outside LIAs such as Hla I-MvTap, Ong Ich Khiem, Nguyen Hoang, Trieu Nu Vuong, Pham Ngu Lao... would beaffected during the entire construction phase, expected to be 12 months.

- Water environment of the Phu Loc river will be affected during construction of LIAThlanhil Khe 5. However, magnitude of impacts will be light because this river will beimproved at the same time.

- Peolpe living within construction areas of alleys will be affected. As the constructionwill be conducted seperately for each alley, the number of affected houLsehiolds ateach construction route is about 20-25 during 1-2 weeks.

- People running businesses at alleys would be affected during construction stage. thatis expected to be 1-2 weeks. However, the number of affected households is small.

- Traffic in LIAs as well as at main transportation routes would be affected dutingconstruction phase.

c. Imiipacts assessmentDuring construction phase of alleys upgrading, the main impacts will be as follows:- Dxtt, air enmission cind noise: within alley area, these impacts are slight and occur

only in short time. For main roads such as Ha Huy Tap road, because meclhanicalconstruction method is applied with 'larger number of construction equipllmellt

operating at the same time, these impacts would be higher and will occur in 2-3 weeksat each section. Impacts at alleys or roads where several items are performed at thc

same time would be larger. During dry season it NVould also be lar,ger than dLiring

rainy season.WofVustewvater and run-offiiwater: temporary flooding would occur during construction,

and these impacts much intesify in rainy season. If construction duration is prolonged,or main and branch sewers are not constructed synchronously, it would lead to largerimpacts on daily life of inhabitants. Water environment of the Phit Loc river would bepolluted by wastewater and run-off water from Thanh Khe 5, bitt these impacts areslight because the river rehabilitation is also performed at the same time. Constructionof sewers requires shallow trenchs, so wastewater and run-off water would not affect

groundwater quality during construction. It is necessary to apply management andtechnical measures properly in order to minimize impacts to human life. ITlhe

measures will be detailed in mitigation section below.Solid wi,aste: excavated soild will be collected and transported daily, so this impact is

negligible. Quantity of domestic solid waste from workers is small bItt if it is not

collected and disposed daily, it would pollute the ambient environment. At the

moment, most of the project areas are provided with in-site solid waste collection

service, so this impact is manageable.Otlier ir, pacits:.* On transportation: excavated soild and material will be transported in and out

during construction. As the main alleys in four LlAs under phase I of the pro'ject

are small with many nairow branches and alleys, whiclh allow mainly manualtransportation with the use of three-wheelers or carsts. Such transportation methodrequires high frequency of moving in and out. In addition, as the populationidensity is high, the traffic is very busy there. Therefore, construction will affect

the residents' traffic, and would be unsafe for elder and children. Traffic jam may

happen in rush hour of construction. Material storage at larger alleys or main roadswould affect the traffic in these areas. However, as the amount of material to be

stored is small and main vehicles there are motorbikes and bikes, this impact is

slight.* Teinlporarv cllt ojf power, waster su1pply, telephone line, cable tivi: due to

replacement of electricity poles, water pipes..., however these impacts are

temporary and in slhort-term.* Social secutrilt: may be changed due to concentration of large number of on-site

workers and materials, machines and vehicles and equipment that will causC

negative impacts to the areas.* Incidents of groulnd subsidence or land slide dullring constru-lction: impacts to

construction works around as a result of drainage trench digging, ground ramminlgT

etc., may occutr as wall breaking or cracks, distortion, foundation subsidence etc..

whiclh may affect the construction progress and cost, compensation or make theic

pollution situation last longer.

Conicluisioni: Main impacts during construction phase include temporary flood fiomiiwastewater and run-off water, traffic obstacle, safety, spreading of diseases. Among 4

upgraded LIAs, impacts in Thanh Khe 1 + Xuan Hoa A LIA, occurim,g mainily at fIla l-IluyTap road, are larger than in the other areas due to large construction qLuantitv. Air

Construction in these 3 resettlement areas will be conducted at the same time witlhexpected duration of 12 months, commencing in June, 2008. Main wastes that will hegenerated during site leveling, constructing infrastrLIcture are identified as tollows:

Dzust, Air emnissions and Noise: At the construction sites of apartment housing andresettlement areas, demolishing the existing works, leveling, soil excavation for thefoundation, vehicle operation will create dust, air emission and noise. Noise isgenerated by bulldozers, concrete mixers and transportation means with noise level of'61.5 - 73 dBA within lOmi radius aroundc construction site.

IV'usleieater and run-off walter. leveling for the resettlement areas constructioll relatedto preventing flow and demolislhing the existing temporary drainage and sewers mayacause partial flood, especially in rainy season. With the number of 50-100 workers oneach construction site and wastewater standard of a worker is 501/day, the volume ofwastewater generated by them is estimated at 2.5 - 5m3/ day. It is therefore necessaryto apply appropriate measure to control this kind of wastewater. As Thanh Khe 'ITavresettlement area is next to the Phu Loc river, construction work would affect the riverwater quality, thereby indirectly affect water quality in Da Nang Bay. Propermeasures for water collection and temporary drainage for these areas dut-illgconstruction phase should be applied.The volume of run-off storm water from these areas during construction is relativelvhigh due to large open areas.Solicd lvastes: include (i) excavated soil during construction and (ii) domestic solidwaste from workers, with the number of workers working at each site of about 50 -100 persons, it is estimated that the volume of solid waste generated at each site issome 25 - 50kg/ day (average solid waste generated is 0.5kg/ capita-day). 'This \Vasteshould be collected and managed properly to mitigate environmental impacts.

b. Affected sutbjects- Air environment in resettlement areas and in 10-20m radius around them milglht be

inmpacted during their construction, expected to last 6-12 months. Air environment atmaini transportation routes such as Tran Cao Van, Luu Quang Vu, Nguyell Khuyewould also be affected during the construction.Water quality of Phu Loc river would be affected during construction of Thanh KlhcTay resettlement area.

- People living around resettlement areas wvould be affected by air emission, noise andvibration during construction phase. Number of affected 11ouseCholds is small becaLusethe selected areas locate in separate residential areas.IPeople and traffic at main transportation routes sLuch as Nguyen Khuyen, Luu QuaLLgVu would be affected by transportation during construction phase.Soil condition at resettlement areas would be destroyed and usage purpose totallychanged in order to construct apartment and infrastructure.

c. ilpacts assessmentt

- DuZlS airemission and noise: air environment at project areas would be affected by

dust and air emission. Dust generated during construction will increase TSP content atthe sites and at main transportation routes. At the moment, TSP at transportationroutes is from 32 times (at access road to Thanh Khe Tay resettlement area) to 65times (at Luu Quang Vu road) higher than standard. Content of noxious emissions atthese routes is still muclh below standard, so during construction, eventhouLgh airenivironiment would be slightly affected by emissions, its parameters will he stillbelow standard. People living along those routes would be atfected by noise due toincreasing number of vehicles. The existing noise level there is low. rangino- fromii 52to 61 dBA. Noise generated by truck is 68 dBA within lOm radius and 62 dBA w ithin20m radius. Thus noise level at project areas is still below standard.

- Wa7sewciter and ruin-off water: The amount of generated domestic wastewater is mlall.However, if it is not collected and treated properly, it would be a potential pollutiollsour-ce to soil and groundwater. If wastewater from Than-h Khe Tay resettlement areais disclharged directly to the Phu Loc river Without any treatment, it will increasepollutanit content there.

Volume of run-off water during the rain from resettlement areas is relatively largewvith high SS content, which would trigger temporary flood if not collected and welldischarged. If run-off water from Thanh Khe Tay resettlement area flows directly tothe Phu Loc river, turbidity and SS content in the river would be increased .

- SolidI wvaste: excavated soild and redundant material w,vill be collected and reused. sothey would not trigger any impacts. Domestic solid waste is generated in smallamounts and will be collected and disposed of daily or every 2 days, its impact istherefore negligible.

- Traffic obstacle: transportation routes such as Tran Cao Van, Nguyen Klhuyen, LuUQuang Vu would be affected by increasing traffic density. At the moment, trafficdensity at Luu Quang Vu road is not high, only 50-60 motorbikes/ h and 5-6 cars/ h.During construction phase, if 5T trucks will be used in transportation, the averagenumber of vechicles on Luu Quang Vu road would be increased by 7 trucks/ Il.Traffic density at Nguyen Khuyen road is relatively high as of 440-1.500 motorbikes/h and 50-100 cars/ h and during construction, it might be increased by 3 trucks/h1. AsTran Cao Van is one of the main roads of the city, it wooud have the same tral'icdensity as at Ong Ich Khiem road witlh 1.300-2.200 motorbike/h and 50-150 cars/' h.T'he number of vehicles at this road would be increased by 9 trucks/ Ii. 1)uriatconstruction phase, traffic jam is possible to happen at Tran Cao Van if transporationis not well managed. Impacts to traffic at LLIU Quaing VU ancd Nguyell KhIluycl roadsare medium.

- Leveling, constructing infrastructure in resettlement areas would destroy top soil,change value of land use eternally. Plant cover at these areas would be destroyed.Hoowever, as the existing vetegational cover there is very poor, with no valulableplants, the magnitude of impacts will be light.

Con7clusion: during constrLIction ph-ase of resettlement areas. air environment slhall beaffected mainly by dust and noise. Wastewater- and storm run-off water are also pollutio0nsources if' they are not well managed. Suitable traffic schedLIle for Tran Cao Van roadshould be applied to avoid traffic jam. These impacts would occur through constructionperiod for 6-12 months.

- l-lousehoulds living within construction area, affected duration is estimated at 1-2weeks for each construction section (10-20m length of embanlkmient or sewver).Affected will be residential areas along the river.

- Some schools and offices could be affected during the construction process, includinuCollege of Gymnastic, Workshop 2 of 29/3 Textile company, Commercial Secondar-yschool.

- Soil environment: soil band and vegetational cover along the river, whiclh are withinconstruction limit, would be destroyed eternally to construct access road andembankment.

- Maini transportation routes such as Nguyen 'Tat Thanih, Tran Cao Van! Dung Sy ThanllKhe road would be affected during construction by increasing traffic density.

- As for the construction of related trunk sewers f'or the LJAs Thanh Khe S and CIhaLnThanhl, the affected subjects are households living within the sites. However, theimpacts are predicted to be partial, occur in short term within only small areas. 'Tlheconstruction will take place at EC road in T'hanh Khe 5, Ong Ich Khiem and NguyenHoanig roads.

c. Impact tissessnmenit

With about 83.8 - 8,380 kg dust generated during excavation within an area of soli61.500n2, the volume of dust is ratlher high if' necessary mitigation measures are n1otapplied. In fact, the amount of dust generated would be even higlher due to possiblematerial spill during transportation and deposited dust as it might be swept Llp bv windand vehicles from the storage. Besides, dust is also genieteared during demolitioin of' theexisting underground works.

A laroe almIount of arising dust shall impact directly the workers because of theil frequLen1tcontact with high dust concentration air and shall brintg inconveniences to daily livin- of'habitants in construction area. The most seriously at'ected subjects are the people wholive near the construction site, especially in dry season. 1-lowever, if the constrLictiowork is diveded (one or two weeks for a construction section), this impact shall happeni illa slhort time and confined scale. Actually, spraying water frequently on construction areais a necessary measure to reduce dust pollution.

5.3.2.1.2 Dust and air emission from construction vehiclesa. Polliution souircesDust and air emission will be generated by construction vehicles in the work areas anidalong transportation routes used for hauling materials. Volume of dust and exhaLust tfMneswill be estimated based on the following subpositions:- About one-third the volume of excavated soil from sewers will be reused as trenichi

backfill, excavated soil along the Phu Loc river will be reused in tillinig theembankment. The volume of filling is about 134,383m3.

- It is supposed that the volume of dug soil that needs to be disposed of and the \Xolulm1eof materials is equivalent with the total volume of excavated soil (8 3,817m3i).

- 5 ton capacity trucks will be used and it could carry about 4m3 of soil or materials pertrip. It is estimasted that 33,596 vehicle trips out/in along 8.000m of constructionroutes.

- Proposed construction duration is 18 moths (from June, 2008 to Decemiibel-, 2009). So.the increasing number of vehicles on all the construction routes is about 8 trips perhour in average.

In the construction phase, a big amount of vehicles that go in and out construction areawill cause environmental pollution by dust and air emission (SO2 NOx, CO. VOC).Based on the quick assessment method of the World Health Organization (WHO), anestimate of generated dust and other key air emissions generated bv transportationvehicles is provided in Table 5-6.

(Note. S - Cotncentrtition of sulphutr infrbel, S 0.3 - 0,5%)

b. Imzpact assessnmenit

According to calculation, concentrations of average pollutioll matter increase on thewhole construction route. Estimated additional concentrationi of dust, SO(D CO, VOC alre0.64, 1.51, 4.24 and 1.84[-ig/m3, respectively.

The main transportation routes for construction are Nguyen Tat Thanh and Trail Cao Vanroads. Based on baseline environment, added witlh dust and air emissions hro-imtransportation vehicles, TSP concentrationi would be higher thani standard, whileconcentration of SO2. CO, VOC are still lower than standard (see the test result of' air-quality in Annex A). Frequent vehicle travels together with large number of constructionequipment that operate concurrently would trigger major impact as it would cause stutfvor uncomfortable feeling for habitants within the areas, particularly foi elder andSchiildren.

5.3.2.1.3 Noise and vibration of transportation vehicles and other constructionequipment

a. Pollttion sources

Noise will be generated mainly by the trucks transportinig materials out/in the site andother construction equipment as well as machinery as excavators, bulldozers ect. [ihepredicted noise levels at calculated points will be defined based on the following tormlaLLt(P1am Ng,oc Dang, 1997):

b. Impact assessmenit

Noise and vibration will be generated from big construction equipmllenlt (bulldozel-,concrete mixer, truck...). It is also caused by demolishing uLnderground works. The typesof noise sources would be as follows:

- Noise from area source: generated primarily from transportation vehicle fleets aLnldwould be triggered along transporation routes within about 8km. In comparison withnational standard on allowable noise level in residential area, noise from transporationvehicle is rather high (68dBA). However, this impact is tncontinuous and short-termll.

- Noise from point source: generated from fixed equipment or operating within narrowarea. At the site, equipment and machines such as bulldozer, pile driver, concretemixer etc. would cause noise impacts with magnitude higher than that from areasource. because noise is generated throughout the construction stage. The highestnoise of tIp to 73 dBA would come from buldozers, within radius of lOm.

-gligh noise level would affect directly health of workers that are operating eqluiplllellt orworking at the site as well as people living within lOm around the site. People livingfarther than lOm would be less affected. The impacts of noise and vibration wouild belhigher in case many equipment operate concurrently.

Pile driving for strenthening embankment foundation would generate high vibrationlevel. As most of the existing houses along the river are of grade 4, the impacts olvibration in long time on their structures would be sig,nificant if necessary measuLes arenot applied.

5.3.2.1.4 Domestic wastes generated during construction

a. Polluition2 soutrces

Dosmetic wastes which are generated during construction process inclucle wastewaterand solid waste by workers at the site. The number of workers at construction site is somilc200, wastewater standard is 501/ capita-day in case workers take bath and wash theirclothes on-site, thus the total amount of generated dosmetic wastewater is 10 m3/ day.Volume of BOD is about 9kg/ day (45g BOD/ capita-day).

Estimated volume of solid waste from 200 workers is some 100kg/day in case of on-sitecooking (average waste is 0.5kg/person-day).

b. Impact assessment

The average wastewater load of about 10m3/dav and the value of BODS and SS; arerather highl. Therefore, it will be pollution source for the Plhu Loc river in case ot directdischarge to it without any treatment.

Volume of daily dosmetic waste from workers is not high (some 100kg/day). 1Hlowever. ilit is not collected and treated, the pollution situation will be more serious and will createspread mosquito vector as well as diaseases to affect healtlh of workers and habitants insurl-oLinding areas.

5.3.2.1.5 Leakage of residual oil and grease

a. PolIlutioII soulrces

In construction process, residual oil shall be generated from preparation or equiplllelntmaintenance process. According to technical document, the average amouLnt of grease tobe changed from each construction machine is some 71 at each change, which needs to hedone evei-y 3-6 months. If the quantity of vehicles and other machinery is 20. the volum11eof arising residual oil and grease will be some 1401/month.

b. Impact assessmenit

Detindable residual oil and grease may be harmfuil waste (code: A3020, Basel: YS).Impact of residual oil and grease will happen in case of leakage in store, overflow watertogether with oil from construction equipment. If there are no strict methods to contr-oltheir collection and removal, whenever they permeate through the soil or get into the PhAuLoc river, the water and ground environment will be polluted.

RLun-off water would be generated from rain water at construction areas and sewertrenchs. from wastewater overflow due to drainage interupption. in process of waterspraying or vehicle cleaning. It has high content of suspended solid and turbidity becauseof soil during construction, of which the most considerable pollution source is rain wateroverflow. Volume of run-off water depends on1 rain intensity, rainning duration and openconstruction area.b. Inmpact assessemenit

- If rain wvater overflow together with gravelly soil is discharged directly to the lh'lLi Locriver without pre-treatment, concentration of suspended subtance and turbidity level willincrease. If it flows to sewage system of the city, it will deposit sediment in chamnbers.Besides, endosmose of rain water to grouLnd in construction area (as holes, wastewaterpumping station) could generate pollution for groundwater in neiglhbouring aLeas.

- In process of spraying road surface or vehicle cleaning, overflow water which has highlSS content and maybe with leakage grease from equipments and machlinery is an implicitpollution source for the Phu Loc river. However, this impact is predicted to be low andinsignfificant.

- The stopped/blocked flow during construction shall temporarily intel-ruplt waterdischarage, causing overflows of dosmetic wvastewater and partial flooding as well aspollution. The Phu Loc river is the main wastewater receiving location of the city, so theimpact is significant during the construction of protective embankments. Dischargeablecapacity of the river shall decrease during construction duratioll because the flow will benarTowed. In case of heavy rain with flood tide, both river banks there would be tlooded.

5.3.2.1.7 Impacts to local trafficIt is anticipated that the increasing volume of vehicles due to the maovemenlt worik is about8 turns of vehicle per hour along the whole implementing route. The roads whichi areplanmed to be main routes for materials transporting are Nguyen Tat Thanh Street andTran Cao Van or Dung Sy Thanh Khe Street. The impact of the increasing volumae oftransportation and vehicles on Nguyen Tat Thanh street is inconsiderable as this street islarge and the traffic density there is light. However, this kind of impact on Tran Cao Van/ Dun, Sv Thanh Khe road and Ong Ich Khiem road is sifilificant since they are rathelnarrow with high traffic density. In addition, there are a numliber of civil houses as well aseducational and training centres in the area.

During the implementation process, piles of soils and stones which have not been takeenaway, or the material gathering fields at the roadworks may cause negative impacts onithle traffic and safety of local residents. Supposing the heighlt of soil, stony piles or pilesof stored raw materials is about 1.5 metre; for each cubic metre of stored material nleededwill be a piece of road of 0.5 metre lengtlh and 1.3 metre width. Material storage will n1otIIImCui affect the traffic during the construction of Phu ILoc river embankment because thearea for building the control lines along the two river banks can be used. Howevel-. incase the wvater sullage pits are implemented on the streets inside the city suchi as the Ong,=Ich Khiem or Nguyen Hoang street, these effects can become significant due to their-narrow wvidth.

When the tide rises, the hanging dregs can be sweptaway up to the upstream area, but this effect can not be accountable because thebeginning point of the Phu Loc river is connected with the water conductilln clanniielof the West Lake. It is estimated that the turbidity level will increase Illost at the riversection that is dredged. However, as dredging activities and method depend on eachIspecific segment of the river, using suitable dredging equipment can reduce this kindof bad effects.

Pollutiioni souirce

During the process of dredging, sediment which lies at the bottom of the river will be aswell as in existing sewers at Trung Tam LIA will be raised. As the stagnated sedinmenithas been accumulated and disintegrated for years, it will generate exhaust ftumes whlellcontacting with the air. The generated fumes consist of Methane (CI-14), SulpuL - lydro(H2S), Carbonic (C02), which are the main flumes that cause unpleasant and bad odor tothe surrounding place, especially in case the work is implemented in the dry season.In case the sediment from Phu Loc river is temporarily kept so as to be dried up beforethrowing away, the organic substances in the sediment will continue to be disintegratedand create uncomfortable odors.

Imppact assess5Ce5tt

Arising sediment at the river bottom will badly affect the environment in termiis ofoffensive odor, especially in the case of the Phu Loc river because the sediment has beenstagnated there for a long time without being dredged. Fumes that are generated consistof Methane (CH4, Sulphur Hydro (H2S) and Carbonic (C02). Such an environment with-a great content of these kinds of gas can influelnce health of the workers and residenitswho live along the river. Although the Phu Loc river catchmenit is next to Da Nang has.due to the high density of houses and the blockage of Thanlh Loc Dan apartment hbilding.

the possibility for the air to be ventilated by winds from the ocean is restricted. As peoplewho live along the river have been bearing the uncomfortable odor for a long timle, thesituation can become even more serious when more bad fumes are createdt durlinadredging. With a great amount of sediment to be dredged out (26.320m3) and a longimplementing time (about 18 months), the effect caused by bad odors is considerable if'no suitable minimizing methods are applied.Dredging sludge from existing sewers at Pham Ngu Lao Trieu Nu Vuong roads would

create offensive order and affect to people living in these areas. This impact miglht occurin 1-2 days at each road.

Inmpact assessment

In case the dredged sediment is temporarily kept onshore for drying up, leachate drippitnlgfrom the sediment, which contains a rich content of suspended solid, when pouring outinto the surrounding areas will bring about pollution. otherwise it can flow backwardsinto the Phu Loc river and increase the suspended solid and turbidity of the water. In caseof rain, leachate may mix with the rain water and then tflows into the households arounldthe site area, causing pollution. Air emission from the continuing process of' or-anicsubstances digestion wvhen being kept temporarily also causes pollution to the air.Nevertheless, this affect is anticipated to be light as there is an empty land tfor thesidewalks along the river banks that can be used for this purpose.

Dredged sludge from existing sewers is liquid and could not stored at the site, it shall besucked by specialized equtipment, stored and transported by tank trucks, so this impacts isslight and short.

d. Oil anid grease from dredging equipmenits

The lubricant in dredging equipment may mix into diluted sediment and drip into theriver in the process of dredging. However, this source of pollution is estimated as beingnegligible.e. Imiipacts to wvaterwaiv traffic

The Phu Loc river outlet is the place where boats and ships of local fishermen areanclhored. This is also an important waterway for fishermen in the East Thanhl Khe Wardto get to Da Nang Gulif. The process of sand sucking requires the water currents to beblocked and separated, which makes the river bed narrower, hence holdingL up thefishermiien's waterway. lowvevcr, this kinid of impact can be reduced by using the methodof implementing the project depending on each segmentation of the river ancl arrangillgthe traffic reasonably, so the ships and boats traffic can easily be organized and acjlustedin most rational way.C(onclusion: The main influences in the process of dredging the stagnated sedimiienitinclude the increase of turbidity level, the cause of air pollution due to emitted gas anidofftensive odor. These impacts are considerable if suitable methods to minimize theimi arenot applied.

5.3.2.2.2 Impacts of transporting and disposing of clredge7 sediment

Dredged nmaterials

in order to evaluate quality of the dredged sediment, sediment samples have been takeni at3 places: (1) At the Phu Loc river's upstreamii, (2) At the downstream point of the city'sdrainiage outlet next to 29/3 Textile company, and (3) near the Phu Loc river outlet. Inorder- to assess the impact of the tide on the quality of sediment, the sediment sampleswere taken both during flood and ebb tides. Criteria related to sediment quality such as:components of sediment grain size, nutrition content, thermal content, salinity. heavv* metals have been analysed in order to propose method for beneficial reusc or disposal ina proper- mannier. The results of sediment quality analysis are presented in Table 5-8 aLndTable 5-9.

- Dredged sludge is liquid, so it slhould be transported to disposal area by taiik truck toavoid leakage to roads.

- Transporatation of dredged sludge would affect the traffic at the nmain transportationroute i.e. Ton Due Thang road. With total volume of'sludge of 26,320rm3. if 5m3 tanJktrucks are used, the estimated number of trucks needed is 10 turns/ clay. It is ratlhelow, so this impact is slight.

- Dredged sludge is saline and has high contents of lheavy metals, so it could not bereused, needs to be properly disposed of. The department of construction introduced aplace for sludge disposal with an area of 3ha at Plhuoc Thuan, Hoa Nhon coimimiunIle,Hoa Vang district. This area should be facilitated with a drying bed to store and drysludge. The bottom of drying bed is wartertight, leachate from sludge with high SSand pollutant content will be collect and treated. So the imapact of leachate is medi-mbut manageable.

- Beside sludge, the remaining part of dredged material is sand. Accordingu to geo-structure survey at the Phu Loc river, the composition of dredged material will be tinesand, so it could be reused for leveling.

- Dredging sand is focused mainly at the river outlet. This amount of sand can beseperately pumped for the purpose of tilling tIp the pipe lines to collect wastewater orfilling tIp the base ground for the resettlment area, hience there is no considerableinfluence.

Conclusion. The main influence created in the process ol' dredging, transporting. andidisposing of the stagnated sediment is bad odor and sediment spills on1 the transportation1way. These influences can be minimized by suiitable methods. Dredged sand can hereused for filling up of the base groLind and does not caLisc any dramatic impact dutiril-iremoval.

5.3.2.3 Accidental landslide of Phu Loc river banks during constructiona. Polititiont souirceDue to the clharacteristics of the river banks wlich lhave a soft soil base grouLtdl and lor along time have been extended with deposits. during the construction of embankment andwater inlet sluices to gather wastewater, deep digging activities may cause the possibilityof breaking and depressing the river bankis. In case the problem occLirs, the broklen soilwill flow into the river, being rolled away with a great amount of sediment and soil.causing the re-pollution effect to the water quality.b. Iimipact assessmenitIn parallel with the dredging activities in the Phu Loc river, the river embankment willalso be bulilt, the river bed widened and deepened. According to the river banlksgeological structure, they are made of soft soil land with a lot of sand. Therefore. clurin-1the digging work to deepen the river bed with the considerable depth (estimated at 4-5metre), the banks may possibly be broken down if the land consolidating activitics andsLiitable implementing methods are not applied.

In case the river banks are broken down, a large amount of soil and stones will be rolledaway downl into the Phu Loc river, whiclh seriouly reduces the water quality. In additiollto suddenly and dramatically increasing the portion of the hanging substances anid thettl-bidity level, stones and soil which get down into the river bed will sooIn stagnate,leading to increase in the amount of sedinient at the river bottom. This effect will notonly occLIr withini the damaged area but also expands its impacts onl the lower sectioni asSOC',ijb/ (117(/ hv17M'ii ()/M7M'tIal Deve1' pme)a71t/J.ohil7 Slockt Cop( [)9/ ( SL78 (SC ) 5--'()

Another impact is on other construction structures in the vicinity. Sinking, cracking maylhappen. in serious cases, houses can even subside at one side or collapse, threatening thesafety of people living inside.

Conclutsion: The impact caused by collapsing of the Phiu Loc river banks to the waterquality and surrounding structures is serious. Hence, during the implementation process.suitable consolidating methods should be strictly followed to avoid the problem.

- Workers that carry out maintenance of sewage system and people living at the site'would be affected. However, these impacts are irregular and occur only in short timle,from half to 1 day.

c. Imp act assessment

- Solicd waste. total volume of solid waste gener-ated from each resettlement site is nothigh. Each resettlement area will be facilitated with solid waste collection tankis thatplaced at sidewalk with distance between tanks is 30m, solid waste will be disposedof everyday bu specialized vehicles, so this impact is slight.

- ,Sewage and septage: as the wastewater load from each resettlement area is small andcis collected and conducted to the city's sewers, then seperated and treated at theWWTP (as mentioned in project alternatives section), the impacts of sewage istherefore slight. Flush wastewater will be pre-treated in households' septic tanksbefore connecting to the combined system. Septage will be regularly suckecd anddisposed of at Khanh Son landfill, hence impact of septage is slight.

- .ir emission: emissions would release offenisive odor at manlholes. This impact isunavoidable and occur mainly in dry season. The impact level would be hignhestduring dredging and maintenance of sewage system. Transportation and disposal of'dredged sludge would impact on tranisportation route and environment at disposalarea. Nevertheless, this impact occur in short-time, from i/2 to 1 day and could hemitigated by proper measures.

C'onclition: impacts durinig operation of resettlement areas are mainly positive. Negativeimpacts occur during dredging and maintenance of sewage system. collecting an(itreatmaenit of domestic wastes. TFhese impacts are however slight and manageable.

5.3.4 Pollution generated in operation and maintenance sewage system

a. Pollu7tioii soutrce

'Fle main waste substanices generated in the process of operating and mainitaininig thesewage system include some odors getting out from the manholes on the network. Themain air emmision is H-7S and some other kinds of gas. The factors that influence the gasemission include temperature, ingredients and characteristics of the wastewater. The airemaissioni is generated as a result of the disintegration process of offensive gas ftromii thestagnrated sediment in the pits and manholes, especially in the dry season.

b. Affected subjects

During- the operation and maintenance of the sewerage system, directly affected will bethe workers who do the periodic maintenance and dredging work. The houselholds wlholive near-by will also be affected. In phase la, the affected people are the ones who livealonig the Phu Loc river, EC road at Thanh Khe 5 LIA, Ong Ich Khiem street and NguyellHoang street.

The sewarage system wil1i mainly brin,g about positive effects. Wastewater is gatlheredand brought to the treatment plant, which helps reduce the pollution by wastewater anclimprove the city environmnent.

The main negative impact during the operation and maintenance process of the seweragesystem is the bad odor coming from the manholes, especially in thie dry seasoll. Tlliseffect is only considerable during maintaining, dredging manholes and drainage clhainnel.The odor is caused by Methane and Sulphur Hydro, generated from the disintegration ofthe stagnated sediment. Both the gases are defined as harmfLul which would cause stufFVfeeling and itch for people who keep contact with their high concentration in a lon, time.especially the wvorkers who regularly perform maitenance work. In order to avoid theimplicit effect and potential danger, ventilation during the work performalnce andlimitation of contact time must be applied.

Conslhision: The impact by bad odor during the process of operation and maintellance of'the sewerage system is unavoidable. However, this impact is not great, only short termand can be minimized.

5.3.5 Phu Loc river in operation phase

n. Pollutfion souirces- Efnlient frmion 29/3 Textile Companjy: At present, Ph- Loc river is receivinlg

wastewvater from the residential areas as well as from the industrial malnufacIL11-iuriactivities. The most serious pollution comes from the Factory No. 2 of 29/3 'TextileCompany. However, since the end of 2006, the company has operated the W\WTP.According to the design, effuent will meet the standard for class B of TCVN 5945-1995. It is planned that the eflfuent fi-om the factory will conveyed to the wastewatercollecting system of' Phu Loc WWTP wvhen it comes into operation. Then, the Plhu

Loc river will not receive the wastewater from 29/3 Textile Company wheni it coniesinto the operation phase.

- Effluenit fromo? Phat Loc WWTY': during opeartion, wastewater of the whole Phu Locand Lien Chieu catchments will be collected and treated at Phu Loc WWTP. Efftientfrom this WWTP will be discharged into the Phu Loc river. This is a pollution sourcefor Phu Loc river and Danang Bay. At the moment, the Phu Loc WWTP has not beenoperated yet. Based on monitoring result at Son Tra WWTP, which is olle of the 4WWTPs of Danang and has the same treatment process as Phu Loc WWTP. BOD5volume in the effluent ranges from 42 to 78 mg/I, typical value is around 70mgI1.while SS ranges from 32.8 to 250mg/l, depending oni quality of influent.

- WVastewater fromn Phia Loc WV'TP in caise of acecidIent: The major source that iancause the greatest pollution level to the Phu Loc river happens when occurs a problermxvith the treatment process of the Phu Loc WWTP. At that time, the river has toreceive a great output of wastewater with a highly polluted substanices with BODWand TSS volumes of 3,950kg per day. However, this case hardly ever occurs. (Sourc.c:.

- In operation phase, all wastewater from Plhu Loc river catchment will be collected andlconducted to Phu Loc WWTP. Phu Loc river catchinent is one of sub-catchments of'Phu Loc WWTP and it is included in design of Phu Loc WWTP. So receivingwastewater from this catchment will neither increase the capacity nor pollutalnt loadsof the Phu Loc WWTP.

- In operation phase, the Phu Loc river will receive storm water and efftulent flrom0l P'hluLoc WWTP. However, the outlet of Phu Loc WWTP is close to Phu Loc outlet (thedistance from Phu Loc WWTP outlet to Da Nang bay is about 200m), so the wNatersources supplementing the Phu Loc river are mainly storm water and the West ILakeirrigation canal. It is expected that the river water quality will be recovered to thelevel as of 2003, when it was only slightly polluted. At that time, BODS contenitranged from 12 - 21 mg/I, SS content was 38 mg/l (Source: report on environncentulcondition lvear 2003, DONRE).

- Mixed BOD5 content in the Phu Loc river at downstream of Phu Loc WW'I'P outletcan be calculated by mass balance equation:

QTXLCTXL + QSCS = (QTXL + QS)Ce

In wvhichi:QTXL : flow of Phu Loc WWTP, QTXL = 59.700 m3/d = 0.69 r13/s (average dry

flow in 2020)Qs : flow of Phu Loc river, assume in dry season, velocity is 0.7rn/s, water

level is 0.66m (equals half of wvater level in rainy season), Qs = 12.4 13/sCTXL : BOD5 content of Phu Loc WWTP's effluellt, Crx1 = 70mg/lCs : BOD5 content of Phu Loc river, Cs = 21 mg/lC,: mixed BOD5 content

As the mixed BOD5 content in the river water is 23.6 mg/l, it is still below standar-cl.Thus, in operation phase, the effluent from Phu Loc WWTP would not impact Xvater

environmllent of the Phu Loc river.The above equation assumes fuilly mixed flow, whicll typically occurs at distalnce ofabout 8 times of channel width downstream from a soirce that is entering from one balnk.The widtlh of the Phu Loc river at this section is 25.8 m, therefore it will take..about206.4m for the source flow to be fully mixed with the Phu Loc flow. The distance tfromlloutlet of Phu Loc WWTP to Danang bay is about 200m, so the water quality in Danangbay would not be affected by Phu Loc WWTP's effluent.- In case of accident at Phu Loc WWTP, the wastewater from the station wNill be

temporarily discharged into the Phu Loc river through the by-pass outlet niear thletipper stream of the river. Applying the above equation, assuming that the BODcontent of the effluent is 150mg/l (according to the design of WWTP), the mixedBOD content is 27.8mg/l. In this case, the Phu Loc river will be slightly im1pacted.however this case is hardly ever seen.

- The major problem to be dealt with of the Phu Loc river during operation period issand deposits at the river mouth. At the moment, the river oulet is usLially seriouslyextended with deposits, which make the flow narrower and cause obstacles towaterway traffic of local fishermen. At t-iis area, it could be observed that water mavstagniate inside the river outlet and can not flow to Danang Bay. If this issue is notsolved, wastewater after being processed at PhlLu Loc WWTP will stagnate insidccriver outlet, causing pollution to the water environment (figure 5-1), thus decreasingthe effectiveness of the Phu Loc river improvement.

6 Mitigation measures

6.1 General principles:

a. Design stage

Designing infrastructure upgrading and sewage system has to observe the regulationlsas follow:

Environmental matters have to be integrated in all the design work and plannillg of theproject. The detailed designs need to minimize adverse impacts on environmenit btmaximizing the use of existing facilities and selecting the location of new facilities inareas where the disturbance to the environment, people and existing struLctures isminimized. .

According to the Vietnamese Construction Regulation Standard Article 3.3 (Protectionof the Natural Resources and Environment), construction projects shLould:

* Not cause adverse effect to environment, and technical regulations on scenery andenvironment protection should be observed,

* Protect natural preservation areas, and historical, cultural and architectural places.* Ensure rational and sustainable use of natural resources, and* Respect traditional customs, practices, and religions of local people.

In the design of drainage and sewerage, attention shLould be paid to preventino thepossibility of contaminating the domestic water supply. Special attention has to bepaid to the possible crossing of water pipes and sewers. For this purpose, it will not beallowed to have water pipes going through the same drainage manholes or boxculverts. If possible, the drainage and sewer systems should be designed to be locatecdas far as possible from wvater pipelines. Discharging points of the drainage systemii hav eto be selected so that the adverse impact is mitigation and the back flow of drainagewater to pipes is prevented or mitigation. Drainage design principles have to beselected in co-operation with the other projects being implemented in the same area toensure consistency between projects and to optimize the effectiveness of tlleconstructed drainage system witlh minimal site and community disturbance.

Upgrading and dredging of channels has to be designed to minimize the needi ofresettlement and to assure proper construction and maintenance access is provided.Transport and disposal of excavated material has to be properly designed andappropriate disposal areas identified and reserved. To minimize transport and off-sitei-impacts, maximum on-site or near site use of excavated and dredged materials will beencouraged. Deposited solid wastes and any contaminated sludge materials which areblocking existing drainage pipelines and channels will be transported to the landfill fordisposal, but most excavated organic materials can be used locally for agricultural andlandscaping purposes. Handling and disposal of sediment and solid waste to specifiedplaces with suitable means of transportation has to be coordinated with relevantantlhol ities.

- Solid waste: construction debris shall be transported and disposal at the city'sdumpsite. Solid waste shall be collected daily and disposed of at Khanlh Sonlandfill. The contractor shall contract with URENCO to transport and disposalthese wastes.

- Traffic obstacle: construction waste, gravelly soil and waste should be quicklytransported out of the area, duration of material storage at site would not exceed 24

hours. Measures to distribute the traffic and transport warning signs shoulcd beapplied while extending roads and sewage system. Coordinating in dealing withLunderground works and waste transporting aims to avoid traffic jam on the roLutesat project areas and surrounding intersections. Trucks shall be restricted cluringrush hours at Tran Cao Van/ Dung Sy Thanh Khe, Nguyen Khuyen, Ong IclKhiem, Ha Huy Tap roads to avoid traffic jam.

- Labor safetv: Detecting mines and bombs during site preparation shall observe thesafety regulations. Relevant authorities will carry out poison/dangerous subtaLniceinvestigations on site and near site of project areas. Health staffs Will watch overregularly to give emergency aid in case of problems. In the areas where theseactivities are being carried out, barriers and dangerous warning sigins shall beraised.

- Mllitigation measures for socio-econoinic ifnpacts:The biggest environmental impact prior to construction is land acquisition anld

resettlement. The project was designed in line with the principle of maximulllllmreducing land acquisition to avoid compulsory resettlement by selecting theoptimal design option. Construction locations and measures are proposecd tobring least impacts to residential areas and culture works. These measures aimto decrease the expenditure of land acquisition and do not violate sensitiveparts in culture and spirit life of people living there (churclhs, tLitelary godtemples of viallages or graves in l-oa Khe and Phu Loc chaninel. etc).

* To limit negative impacts generated by site clearance, "Resettlement polic'framework" and "4Resettlement plan" were developed durinig the projectpreparation shall set orientation for all resettlement activities. I'hese reportsdeal with principles, objectives and criteria of affected people. compensationlinterests, legal frameworks policies, compensation measures and supports,participation of habitants, complaint procedures ancd resolving. which aim toguide activities of compensation, resettlement and restore supports t'oraffected people. The proposals were developed based on the WB Safeguar-dPolicy for Obligatory Resettlement (OP 4.12), Vietnamese legislation andstipulations and guidance of Danang PC which are related to resettlemienltpolicy.

* For affected people, especially the ones to move to new houses. needledl issome support to recover their living standards at least to the same level asbefore moving or as the existing living standards prior to the projectimnplementation (depending on which is higher).

The site clearance activities for Thanh Khe 5 LIA, Phu Loc river area and Thanhl KlheTay resettlement area should be arranged at the same time to reduce impact period.

- There are 3 types of dredged materials: (i) top sludge, (ii) sand frolmi the PhLi locriver and (iii) sludge from the existing sewers.

- According to analysis results, salinity and concentration of heavy metal in topsludge from Phu Loc river is relatively high, so dredged sludge is not suitable forreuse for agriculture purpose and should be disposed of.

- Top sludge from the river and sludge from existing sewers are liqluid and couldc notbe stored in the site. They will be stored and transported by tank trucks or tightcovered trucks. The contractors shall contract with IJRENCO to transpor-t anddispose of such types of sludge. These sludges will be disposed of at the city-ssludge diposal place, which is proposed at Hoa Vang commune. Sludge will bedried and disposed properly. Bottom of drying bed should be watertighlt. Leachatefrom sludge shall be collected and treated before discharging to receiving \Naterbodies.

- Dredged sand from the river shall be stored and dried up at the site. 'I'here are manyvacant areas along both sides of the river, thus dredged sand is proposed to bestored temporarily at these vacant areas. Dry sand could be reusecl for road base.filling Phu Loc embankments or Thanh Khe Tay resettlement area.

7.2 Contingency Plan

7.2.1 Ricks identifications

Risks during design stage:

During design stage, risks that may arise are often related to designers'

inexperience and lack of appropriate skills which result in inaccurate

calculation results. They may also relate to unthorough control of the design

supervision unit, unsuccess in predicting the trends of infrastructure chanigzes

over time (changes in the city's planning, self-upgrading by houselholds thaLt

cause diffrences in works elevations, flow direction, upgradiiig scale etC.). SLIch

risks will bring about systematic difficLulties durinig constrLuction, especially

during operation.

Risks during construction stage:

During construction, in addition to the environmental impacts already

determined in the EIA such as ducst, noise, temporary inundation, traftfic jamll,

construction debris etc., the project may also encounter such risks as labor

accident, traffic accident, fire and explosion, diseases related to di'estion.

respiration etc., or dispersion of toxic substance into the environment. breaklilln

or cracking of houses or public building in the vicinity of the construction site.

leading to the need for compensation, remedy. The risks also include the

residents' complaints or grievances due to serious impacts on their healtlh

resulting from pollution or damages to their assets. More serious would be the

cases that are given in the media or related to factors difficult to define SLICIh LIS

war explosives residual or toxic substances discovered during excavation. As a

result, the project would bear serious loses such as impacts on people's lives

and properties, public buildings, loses in finance, delay in project progress. lose

of' donor's confidence, unsuccess in reaching the planned objectives, or in the

worst case, even the project woLuld be stopped .

¢ Risks during operation stage

Socicil anditl Environmental Developmiient Joint Stock Com17palllnJ (SECO)

Danang Priority Infrastructure Investment Project Environ?mental Assessmenit Report - Phase lI

In case the project's design and construction as well as its hand-over are

successfully completed, risks may still arise during the operation. Such rislks

mainly relate to the responsibilities of operators. They may also be as a resLIlt of

improper design or construction quality and just arise durinig this stage. not

earlier. The risks also may include the outbreak of diseases in the areas il the

vicinity of outlets, excessive amount of toxic substances cominlg trom

production units that exceeds the treatment capacity, serious break down of the

works resulting in inundation, accident to pedestrians etc.

7.2.2 Content of the Contingency Plan

Identify undesired and potential risks

Assessment of risks

Having defined the risks qualitatively, more quantitative informationi shIoulld

be determined, thereby to clearly identify their level, grade as well as

needed scale of relevant contingency plan. The main lactors to be

determi-ned are as follows:

V Probability of the risks to happen,

* Impact magnitude

* Duration

* Impact subjects

* Possibilities to identify their symptoms, traces

* Need time for reaction

Classification of risks and identification of risk indicators

Risks that may be more serious shall be throughly selected and analyzed. A

classification system with related criteria shall be made for the risks and

needed reactions accordingly, depending on the risk grade.

Design of a suitable contingency plan

Based on the risks assessment, necessity of the plan would be determined in

order to make it able to be smoothly operated and cases of emergenic) able

to be quickly dealt with, depending on specific cases (grade, manrlitlde.

impacted subjects etc.). A plan to regularly reviewv reports in order to

cliscover the risks as early as possible shoulcl also be macle.

This will help make the reaction plan more smooth and effectiv e in

operation. The reaction plan shall be regularly updated so that corresponcles

to the actual situation of the project. Its dissemination and digestion as well

as periodic control of reaction capacity shall be strictly followed.

Content of the Contingency Plan Manual shall be developed after the EIA

report is approved to set the base for relevant managemiient agencies in

managing the risks that may arise during the project implementation.

7.3 Monitoring program

Monitoring and assessment activities in period of land acquisition and alter

resettlement phase aim to ensure land acquisition and land resettlement activities are in

compliance with specific regulations and guidanice in approved resettlemenlt planl.

Stakeholders will be provided with continuous situations of implementation. These

activities will assist in assessing actual posibility of success and arising troLibles, thIls

activities could be adjusted accordingly. RAP will be applied in surveys anid

monitoring will be conducted based on size of sample. Sampling scale may be miadle

for 100% of households tlhat have to move and seriously affected and at least 10% ofremaining househoulds. Key monitored parameters are:

- Compensation for affected people in accordarnce with different levels of

compensation policy in RAP;

- Teclhnical assessments, subsidy and support for moving;

- Restoring income and right to receive support;

- Information disclosure and community consultatioll;

- Following complaint procedure and exitsting issues which require managementattention;

- Giving priority for affected people about proposed selections;

- Land acquisition schedule.

Assessment after resettlement shall be carried out 6-12 months after conmpletion ofresettlement activities. Monitoring offices that comprise internal imonitoring anid

environmental condition at preoject areas, except Nam Duong Ward add that thearea from Ma Voi market to back of Phap Lam pagoda is sunken, it is usuallyinundated after raining with flood height from 0.8 to I.2m. Flooding has pollutedwater resoures and environment, created condition for epidemic diseases. Airenvironment around the Ma Voi market has been polluted bv odor from solidwaste with large amount, people also throw garbage at this area.

b. Impacts and mitigation measures during construction: all wards agreed thatimpacts identified during construction are unavoidable and required the project toconform to proposed mitigation measures. In addition, they also added othermeasures as follow:- Construction shall be carried out quickly, avoid prolongation.- Drainage system of Hoa Minh resettlemenita area shall conniiect to existilin

sewers at North West new urban area.- In case transportation triggers damages of existing roads, necessary

rehabilitation shall be taken.- During construction of Phu Loc river, it is necessary to propose mititipholl

measures in order to minimize damages of structures, compensate to alf'fectedassets.

- Construction of Thanh Khe S LIA should be done in each area. It shoLIld n1ot tiecarried out for the whole LIA simultaneously to avoid impacts on local trafi'tc.

- Business at Ma Voi market and along upgraded roads shall be at'fected dulilliconstruction stage. The project should have measures to support afct'ectpeople.

Moreover. in this assessmeent process. wehave the references from the inhabitant commnunity in the project area. P'eople'sCommittee of the district, People's Committee of the ward and other organizationissuch as Association of Women' Union as wvell as the suggestions of the leadina0environmental specialists. Therefore, the report has the highly accurate and et'ectiveeffects. However, in the implementation process, there are many shortcomin-s suclh as:the subjective idea of the examiner, the reliable limit of the documents as referenices,the en-or in the method of measuremiient, the method of picking up the samples as wvellas the way to analyze the samples, etc... However, this is the error whichi is in tlheallowed limit so it does not affect much on the result of thle report.

10 Conclusions and petitions

10.1 Conclusions

The Priority Infrastructure Investment Project is a significant and multi-sectoralproject and most of the environmental impacts in operation phase are positive impacts

that actively contribute to the improvement of environmental quality and sosio-economic of the city. However, in the implementation phase, it is possible that therewill be some negative impacts to the natural environment and social environment. I'heneoative impacts to social environment mainly arise in the site cle.irance and

implementation phase.

In site clearance phase, the most considerable impact is disodering through activitiesas: clearance, resettling a big amount of h ouseholds, moving a big amount of' graves

and even violating several cultlral works. These impacts are quite considerable.

Moving and resettlement for affected people shall cost a big expenditure. At presenit.there are still fund of land for resettlement. thus these impacts are able to mitigate aindrepair because of appropriate Resettlement Policy Framework. Impacts of' culturalworks are not much and could be avoid in case of good and strict implementation ol'environmnetal management procedures.

In construction phase, primary environmental impacts are dust, noise. traffic, qualityof water and public security. Impacts of sediment dredging from Phu Loc river are bad

ordor and increasing turbid level. These impacts are temiporary in construction phase

and they could be mitigated by strictly implementing environmental managemientprocess. In brief, environmental impacts are not considerable or temporary andcl able tomitigate by appropriate environmental management in project implementation.

The evaluation mainly bases on the process of examining the lield work, thletheoretical principles, the modeling methods aiming at providing initial database ot'theimpacts and solutions in needs. However, in thie im1plementation phase, there should besome adjustments incompatible with the real situation at the project area. Moreover, agood implementation of mitigation measures and environmental monitoring plan alsoconsiderable contribute to the reduction of environmental pollutions.

10.2 PetitionsThe priority infrastructure investment pro ject will clhange some aspects of' theeconomic and social situations in the region. Poverty reduction of some wards in projetarea shall be carried out through upgrading technical infrastructure and environmlenltalconditions as well as the improvement of living standard for the poor in the city. Dueto the requirement about the rate of progress, we respect to suggest the Departmenit ot'Natural Resources and Environment appraise the EIA report as soon as possible ainicsubmiiit it to the People's Committee for approval.

a) There are some additional suggestion about existing environmental conditionsas below:

- The weakness sewage and drainage system has caused tlooding in many areas,including:

+ C3 sewer in Nguyen Van Linh is tlooded and blocked, thus waste watercouldn't discharge and it smells.

+ Road is flooded whenever it rains, especially at the depth Im (at lane 82).+ The middle area of Nam Duong market has low terrain so that waste and waste

water are stagnant. Therefore, the surrounding residential area is seriouLslxpolluted.

- Noise, vibration and smell from small factories such as Paper F'actory. IceFactory .etc.

b) Environmental impacts and mitigation measures during constructioni andoperation phase:

- Most of households accepted impacts and mitigation measures dcuringconstruction and operation phase. However, there were 3 households (3/ 18)living in Ong Ich Khiem road did not accept because they thought that existingintirastructure has been good and upgrading has been not necessary. Thev didnot accept the impacts to their business during construction phase.

- Construction period shall be predetermined and item constructioni shall becomprehensive.

- Construction waste shall be collected and transported quickly out off residenltialareas.
