This EMP is constructed by the Environmental Technology Center (ENTEC), part of Vietnam Association for Conservation of Nature and Environment (VACNE). The contents of the plan is as below PROJECT CONTENTSDescriptionAim: to satisfy the increasing in number of firms within the IP and the arisen demand of wastewater treatment through the development of Module 2 CETP ,capacity of 2,000 m3/day” (the total capacity of two modules is 4,000 m3/day and night) Project Owners: Nhon Trach 3 IP One member Affiliated Co., LtdSite Location: Road No. 2, Nhon Trach Industrial Park No. 1, Phase II, Nhon Trach District, Dong Nai Province. The Module 1 centralised wastewater treatment system have original capacity of is 2,000 m3/day the system ahs been receiving and treating wastewater of operating industries in the industrial park. Currently the average wastewater volume is 884m3/day; nd peaked at 1,169m3/day. By November 2012, the total wastewater volume of Nhon Trach 3 IP, Phase 2 will increase to around 3,000 m3/day. To properly collect and treat this wastewater, Tin Nghia has been developing the second module to expand the total capacity of the wastewater treatment facility of Nhon Trach 3 IP, Phase 2 to 4,000m3/day.CETP treatment technologyWastewater from Nhon Trach 3 IP, phase 2 is treated by two steps as follows: 1st Step (facilities own treatment): the wastewater from private companies will be treated preliminarily, to meet the influent standard of IP centralised treatment plant. 2nd Step (centralised treatment): Preliminarily treated wastewater is collected into the centralised treatment facility of the industrial park for further treatment ( and meet the QCVN 40:2011/BTNMT – National Technical Regulation on Industrial Wastewater, Column B, Kf=1.0, Kq=1.1) prior discharging into the environmentModule 2 technology for Nhon Trach 3 IP CETP can be described as below: Preliminary and Primary Treatment:+ Removal of wastewater constituents (rags, sticks, floatables, grits…).+ Chemical treatment (mixing and flocculation).+ Removed floating oils and greases.Secondary treatment (remove biodegradable organics):+ Aerobic treatment to removal biodegradable nutrients, BOD, COD.Tertiary treatment:+ Advanced treatment by remove residual suspended solid and dissolved materials.+ Disinfection.Sludge treatment:+ Dewater and compact the dried sludge.CETP characteristicsThe effluent after treatment will be flown through the open ditches B4000, then closed pipes B3000 before being directed along the upper stream of Lo Ren canal (along regional slopes toward southeast), and finally being discharged into Thi Vai River.The discharge schedule is 24 hours a day.Discharge flow rate is 84 m3/hr (or up to 2000 m3/day)CETP implementation schedulesJune/ July 2012: Finished legal worksAug-Dec 2012: Start the constructionJan 2013: Implement equipments, pipeline networks.Feb 2013: Pilot RunMar- Apr 2013: Technology and system transferingCHARACTERISTICS OF WASTEWATER RECEIVING BODY BASINDischarge pointsDischarge point: Lo Ren Culvert (near Lo ren Bridge) and at coordinates (VN2000):X: 1.184.745 m;Y: 413.438 m.Characteristics of wastewater receiving body Thi Vai River is the wastewater receiving body for all of Nhon Trach 3 wastewater and currently is heavily polluted due to wastewaters from nearby sources. River flowrate mixed with flood is peaked at 3,400 m3/s, with river with tide reverse flow peaked with tide at 2,300 m3/s. River flowrate during wet season is around 350 – 400 m3/s and during dry season is around 200 m3/s. The minimum recorded flowrate is 40 – 50 m3/s. The highest river speed could reach 1.5 m/s. Thi Vai River based on Dong nai Province planned landuse, is for aquaculture farmingNearby discharge sources Nearby discharges sources into Thi Vai River is as below:Industrial sources: Discharges from Hung Nghiep Formosa, Nhon Trach 2 and 3 IPs, with a flowrate of approximate 20,500 m3/day Agricultural sources: The total volume of wastewater from aquaculture activities discharged into Thi Vai river is estimated at 7,043,760 to 9,391,680 m3/farming season. Most of these wastewater is discharged only after harvested (after around 3-4 months)Residental sources: Domestic wasteater from Long Tho Commune, Nhon Trach District and Hiep Phuoc District is 1,467 – 1,956 m3/day.Nearby water supply intake Within 3 km downstream of Thi Vai (from Mareng discharge point), there’s no river water intake sites, even for industrial or aquaculture purposes. Current environmental statusAir quality: The analysed sampling results from nearby air quality samples showed all parameters met QCVN 05:2009/BTNMT, QCVN 26:2010/BTNMT, and QCVN 06:2009/BTNMSurface Water quality: The analysed sampling results from nearby surface water quality samples comparing to QCVN 08:2008/BTNMT, column B1 showed parameters like COD, BOD and TSS over the standards.Soil quality: The analysed sampling results from soil samples showed no heavy metal pollution ALTERNATIVE SOLUTIONDischarge point locationAs the Module 2 used the same discharge point with the Module1, hence there’s no alternative solution for the discharge point locationWasteawter treatment technologyAs the Module 2 have to integrate into Module 1, hence there’s no alternative solution for the already chosen technology in Module 1Sludge treatmentAs the sludge treatment of Module 1 still can provide the extra capacity, hence the Moduel 2 still use the same method as Module 1DISCHARGE IMPACT ASSESSMENTOn water qualityAfter the Module 2 start operating, a flow of 2,000 m3/ day will contribute into Mareng Canal flow, bring with it an equivalence of 31.6 kg TSS, 14 kg BOD5, 104 kg COD, 0.76 kg ammonia and 0.36 kg Total ironOn the ecologyCurrently, there is no expected impact by the discharge onto the ecology and mangrove areas downstream (Long Thanh – Nhon Trach areas)On river flowThe discharge rate from the CETP (Module 2) is insignificant comparing to Mareng and Thi vai river, hence won’t affect the river and canal flowOn air qualityThe discharge from The CETP does not produce odour as from the interviews toward the residential areas and hence does not impact onto regional air quality Associated risks and accidents Due to the low discharge rate 2,000 m3/day or 23.14 l/s, the discharge won’t affect the travel of canoes on the canal and rvierSocio-economical impactsThere’s no negative feedbacks from the nearby residential areas (around Mareng and Thi Vai) on whether their socio-economical situations are affected by the projectAccumulated and integrated impactsFor Ma Reng Canal, after received the treated wastewater from the IP will still be able to sustain the loads of parameters BOD, SS, As, Pb, Cd and Hg. Only COD already over the river maximum pollution loads; due to the current pollution load of Mareng is already higher than the Canal max pollution load. In that way, even when the pollution loads from the CETP contribute unsinificant amount, the river still can’t receive more loads.Similarly for Thi Vai River, after received the treated wastewater from the IP will still be able to sustain the loads of parameters BOD, COD, As, Pb, Cd and Hg. Only COD already over the river maximum pollution loads; due to the current pollution load of Mareng is already higher than the Canal max pollution load. So even when the pollution loads from the CETP contribute unsinificant amount, the river still can’t receive more loadsPOLLUTION MITIGATION TOWARD NEARBY SURFACE WATEREnvironmental Management ProgramConstruction stagesWater pollution mitigation measures Air pollution mitigation measures Mitigation measures for smpacts from solid wastesOperation stagesWater pollution mitigation measures Air pollution mitigation measures Negative impacts mitigation for solid wastesNegative impacts mitigation for sludgesRisks managementsConstructs stagesMeasures to prevent and mitigate the impacts of these risks:Risk of fires and explosions Traffic AccidentsRisks associated with labour and health safety Operation stagesMeasures to prevent and mitigate the impacts of these risks:Risk of fires and explosions Risks associated with labour and health safety Chemical leakageThunder/ lightning Impactsassociated when the plant stop operatingPublic consulting and Information publicationDuring the construct of this EMP, the project owner have consult the local government (People Committee, Fatherland Front Committee) and the residents living in affected areasCapacity buildingThe project owners will carry own measuress to strengthen the capacity to react against environmental and CETPworkers health risks.Project owner organisation and responsibilties The issues related to environmental management will be implemented by the CETP Environmental Department as regulated planEnvironmental quality MonitoringThe project owners will be responsible for the monitoring of nearby surce water sources, along with the periodic sampling of Nhon Trach 3.

The project owners will under full responsibilities if violating Vietnam regulations or International Convention INTRODUCTION OF THE PROJECT BACKGROUND“Socio-economic development in line with environmental protection” is a proper sustainable development policy which was selected by all of the members under United Nations. It therefore considered seriously by the Vietnamese Government to address and minimize any negative impacts in the country quest of industrialization and modernization. In compliance with the existing regulations over the environmental qualities within and surrounding Nhon Trach 3 Industrial Park, Tin Nghia Corporation have invested in the implementation of a centralised wastewater treatment system (Module 1) in Nhon Trach 3 Industrial Park- Phase 2, capacity of 2,000 m3/day and night. This Module 1 central wastewater treatment system was officially put into operation since November 2007, meeting wastewater treatment requirements and demands from Nhon Trach 3 Industrial Park, and Vietnam environmental regulationsHowever, under increasing number of facilities within the industrial park, the wastewater discharge demand has been increasing rapidly. That’s why the project entitled “Development of the Central Wastewater Treatment System, Phase 2, capacity of 2,000 m3/day and night (the total capacity of two phases is 4,000 m3/day and night) has been proposed to meet the wastewater treatment demand in the industrial park.

The wastewater discharge system of 20 operating industries has been connected to the centralised wastewater treatment system as signed under wastewater treatment contract with the Infrastructure Management Unit Among them, 7 already have their own treatment systems for pre-treatment before being discharged into the centralized wastewater treatment system, they are: Viet Long Packing Co. Ampharco Cosmetics Joint Stock Co. Ltd, Bueno Technique Co. Ltd., CSB Battery Co., Ltd And Sammi Co., Ltd. Plus Vietnam Industry Co., LtdY.S.P Vietnam Co., LtdThe Module 1 centralised wastewater treatment system have original capacity of is 2,000 m3/day the system ahs been receiving and treating wastewater of operating industries in the industrial park. Currently the average wastewater volume is 884m3/day; nd peaked at 1,169m3/day. Wastewater is treated to meet Vietnam National Regulation QCVN 40:2011/BTNMT; column B, Kq=1.1; Kf=0.9 prior discharging through Lo Ren Discharge Point, and ultimately into Thi Vai River.The Phase 2 addition of the treatment facility was examined and certified by Dong Nai Department of Natural Resources and Environment at Official Document No. 652/TNMT-CCBVMT dated March 18, 2010 and by Dong Nai People’s Committee under license No. 3571/GP-UBND in December 1, 2009 (see attached documents in the appendix).The company also has installed an automatic monitoring system to monitor the effluent quality (pH, DO, TSS, COD, temperature). Wastewater Collection and Discharge System of the Industrial Park Wastewater Collection SystemThe sewage system was entirely developed by Tin Nghia Corporation.The slope is inclined toward south west: with the elevation varies from 1 to 3.5 m. Wastewater is classified into two storing basins N1 and N2. In each basin, the wastewater is ran through reinforce concrete box culvert D300 – D400 – D600 and through the primary culvert system D800 – D1000 – D1200 to the centralised wastewater facility via D1500 culvert line. The wastewater discharge culverts are RC culvert, with manholes at the interval of 40-50 m along the culvert long. The sewage system covers total length of 15,704 m, comprising of D300 = 10,038 m, D400 = 1,777 m, D600 = 1,489 m, D800 = 982 m, D1000 = 1,188 m, D1200 = 210 m, D1500 = 56 m.The treated wastewater is discharged to the environment via open ditch concrete culvert canal (B4000, 235 m in length) and closed box culvert (B3000, 524.3 m in length) before being discharged into Lo Ren canal, and ultimately ends up in Thi Vai River. Drainage SystemTin Nghia Corporation also developed the drainage system. The drainage system is the RC culvert, covering 30,211.4 m long, comprising of D600 culvert = 2,042 m, D800 = 6,905.6 m, D1000 = 7,020.2 m, D1200 = 485.6 m, D1500 = 11,254.2 m, open ditch B2000 = 997.5 m, B4000 = 982 m, and closed box culvert B3000 = 524.3 m.People’s Committee of Nhon Trach District has only invested in the development of the drainage system along Road 25C. Comapnies along Road 25C (in Nhon Trach 3 IP, Phase I and Phase II) will have to continue the development and connect to the drainage system. When the local goverment develops the drainage system along Road 319B, the private sector will have to continue implementing a drainage system to connect from Youngtex Vina to the current oneThe stormwater in Nhon Trach 3 IP, Phase II is collected into the above concrete culverts, is run along the internal roads before being discharged to open ditch (the same one hosted the treated wastewater from the central wastewater treatment system) then being discharged into Mareng canal, and ultimately ends up in Thi Vai River. . Wastewater Treatment SystemWastewater from Nhon Trach 3 IP, phase 2 is treated by two steps as follows: 1st Step (facilities own treatment): the wastewater from private companies will be treated preliminarily, to meet the influent standard of IP centralised treatment plant. 2nd Step (centralised treatment): Preliminarily treated wastewater is collected into the centralised treatment facility of the industrial park for further treatment ( and meet the QCVN 40:2011/BTNMT – National Technical Regulation on Industrial Wastewater, Column B, Kf=1.0, Kq=1.1) prior discharging into the environment The existing firms with prelimary treatment systemFacilities in Nhon Trach 3 IP (Phase 2) which already have own prelimary treatment system are:NoNameWw discharge rate (m3/day)1Viet Long packing Co., Ltd.702Ampharco Cosmetics Joint Stock Co.173Bueno Technique Co., Ltd. 264CSB Battery Co., Ltd (Vietnam)1885Sammi Co., Ltd.66Plus Vietnam Industry Co., Ltd12?Total319As seen in above table, the total ww discharge from the 6 firms are 319 m3/dayThe under construction firms with preliminary treatmentThere is only one firms which currently under construction and already have preliminary treatment plant being set under plan, that is the Y.S.P Vietnam Co., Ltd. with discharge capacity of 6 m3/day.The module 1 ww treatment systemModule 1 of Nhon Trach 3 (Phase 2) CETP have the capacity of 2,000 m3/day, and already under operation since 11/2007The module 2 ww treatment systemSome facilities are currently under construction at the IP, and already sent the notification on the expected operation time in 2012 and the estimated discharge vlomue.

The first stage of the preliminary treatment process is the fine screening and grit removal to remove wastewater constituents with diameter larger than 1.5 mm. Next is the wastewater equalising tank with mixing to equalising wastewater characteristics, avoiding sedimentation and anaerobic process. The tank also being injected with chemical to stabilise pH levelIf the wastewater have high concentration of heavy metal or colour than designed characteristics, the wastewater will be treated with chemical through flocculation and flotation process in primary clarifier. The clarifier will separate the residue/sludge from influent, before it’s running through grease trap. The wastewater with low concentration of heavy metal or colour than designed characteristics, will still be ran through primary clarifier, however the flocculation and flotation process won’t happen.At the grease trap, grease will be separated from wastewater and stored in different container. The main body of wastewater will then be treated in the aerobic tankThe wastewater after being treated with the aerobic process, will be run through the secondary clarifier. Some of the sludge from the secondary clarifier will be fed back to the aerobic tank to provide the foods and maintain the level of microorganism inside the aerobic tank. The rest of the sludge will be pumped out for dewatering and further treatment. The treated wastewater will then be pumped into disinfection tanks for disinfections and monitoringThe stabilising pond acted as buffer to further treat the water before it’s released into the environment On sludge treatment: sludge from primary and secondary clarifiers will be pumped out for solidified and dewatered (with mixing). Solidified and dewatered sludge are mixed with polymer before finally being compressed. This mud, and the greases from the container will be treated as hazardous wastes. Water from sludge in these processes will be pumped back and mixed with the influent.Industries’ own treatment systemAt this moment, the IP has 9 firms with their own ww treatment system, before being discharged and treated again in the centralised treatment plant.

This continues to flow southeast down the slope across terrain, receiving wastewater from residential areas along the canal, before running through Ma Reng Canals and finally being discharged into upper Thi Vai.Agricultural SourcesIn addition to industrial wastewater, the regional agricultural activities also contribute significant amounts of discharges into the Thi Vai River. Currently the main agriculture activities here are quite diverse: fishing, animal livestock, horticulture…. But the majority of wastewater is still generated by aquaculture activities (farming black tiger shrimp, white shrimp, and other types of fishes). The farming areas are distributed across Long Phuoc, Phuoc Thai Communes (Long Thanh - Dong Nai), Long Tho and Phuoc An Communes (Nhon Trach - Dong Nai) and My Xuan commune, Phu My town (Tan Thanh, Ba Ria - Vung Tau). This type of wastewater from shrimp farming arises mainly after the shrimps were harvested. As the farmers live on both sides of river banks often works in small scale/ household business (about 1-2 ha in farming area), they simply can’t afford an appropriate treatment system for these wastewater. The wastewater from shrimp farming, include ponds water with food scraps, wastes, and used biotic; is currently being discharged directly into the Thi Vai River without treatment.According to survey data of Le Van Thu - Project "Investigation and proposing solutions for the development and protection of mangrove ecosystems in Long Thanh -Nhon Trach" in 2005; the mangroves areas in two districts of Long Thanh and Nhon Trach, have a total area of shrimp farming is 782.64 ha. This generate an amount of wastewater approximate 9000-12000 m3/ha. In another words, the total volume of wastewater from aquaculture activities discharged into Thi Vai river is estimated at 7,043,760 to 9,391,680 m3/farming season (or 58,698 to 93,917 m3/day due to a 100-120 days/farming season). However, most of these wastewater is discharged only after being harvested (after around 3-4 months) so there is always a concentrated amount of discharge by the end of this period rather than distributed evenly into daily.Domestic Uses SourcesIn addition to the industrial and agricultural wastewater, the wastewater from nearby residential areas also should be mentioned. The demographic of those residential areas: Long Phuoc and Phuoc Thai Communes (Long Thanh - Dong Nai Districts ), Hiep Phuoc, Long Tho and Phuoc An Communes (Nhon Trach -Dong Nai Districts), in addition to Xuan My Commune and Phu My town (Tan Thanh district, Ba Ria-Vung Tau District) are as follows.Table SEQ B?ng \* ARABIC 13: The demographic of nearby residential areas to Thi Vai riverNoResidential AreaPopulation1Long Thanh District – Dong Nai ProvinceLong Phuoc Commune10,4022Phuoc Thai Commune13,1053Nhon Trach District – Dong Nai ProvinceHiep Phuoc Commune10,3384Long Tho Commune5,9595Phuoc An Commune6,5476Tan Thanh District, Ba Ria- Vung Tau provinceMy Xuan Commune12,3837Phu My Town8,797Total67,531Standard wastewater discharge per capital of households with sewer system, but without bathroom is ranged from 90-120 liters/capital/day (Nguyen Trung Viet, 2005). If apply that to the residents along Thi Vai River with a population of 67,531 residents, the daily discharged wastewater can be estimated at 6078-8104 m3.However, at present, these residential areas still either does not connect to public sewer systems, or connect to an incomplete system. This means the majority of these domestic wastewaters are still left to run-off and eventually infiltrate into the grounds. That’s why the amount of discharged wastewater directly into Thi Vai River can be considered negligible.Nearby Water Supply Intake (within 3 km downstream)The water quality of nearby open water source is much lower than the requirement for water supply source (mostly due to salinity) . Therefore the main use of them is for river transportation and aquaculture. Along the Mareng and Lo ren, there is no water supply intake structure. Only the residents lives near the meet between Mareng and Thi vai working in fishing, and no river water was used for farming .3km downstream of Thi Vai (from Mareng discharge point), there’s also no river water intake sites, even for industrial or aquaculture purposes.

There are total 261 floral species of 61 families and 184 branches. They belong to Magnolyophyta, Magnolyopsida and Liliopsida.Long Thanh – Nhon Trach mangrove forest is in the submerged land of the province, contributing to stabilize deposited alluvium, forming a protective wall, preventing river mouth erosion which is caused by tidal and other activities. The mangrove forest plays significant roles in maintaining the eco-balance, including alluvium transporting and movement of plankton, balancing fish and shrimp larva resources. The mangrove forest is managed by Long Thanh Farm, covering the area of 4 communes: Phuoc An, Long Tho (Nhon Trach district) and Phuoc Thai, Long Phuoc (Long Thanh district). The inland waterway transport system is densely in the forest area, favorable to transport and ecotourism development. It is estimated that the total natural area of Long Thanh – Nhon Trach mangrove forest is 7,952.67ha, comprising:7,060 ha in Nhon Trach district (4,036 ha with forest trees and 3,024 ha without forest trees).1,467 ha in Long Thanh district.Plant PlanktonThe salinity-polluted zone is affected by industrial wastes. Number of species in this zone is less diversified, comprising 29 species where Bacillariophyta is dominated with 17 species or 58.6% of 10 families; following by Chlorophyta with 6 species or 20.7%, belonging to 6 families; Cyanophyta with 4 species (13.8%) of 4 families; Chrysophyta with one species (3.4%); and Euglenophycota with 1 species (3.4%). The average density is 19,000 to 45,000 individuals per 1 litter.Zoo Plankton and Zoo Benthos In the salinity polluted zones which are affected by industrial wastes, Copepoda species are dominated with 11 species, 20 initials per liter; following by Rotifer – 2 species, 8 individuals per liter, Protozoa – 5 species, 7individuals per liter, Cladocera – 11 species – 3 individuals per liter and larva – 38 individuals per liter. Crustacean19 valuable shrimp species are identified, especially Penaeus indicus, Metapenaeus ensis; Metapenaeus lyssianassa Metapenaeus spinulatus is an important species in intensive rearing ponds in Long thanh and Nhon Trach. Scylla serrata crab is also exploited in mangrove forest. Regarding Penaeud monodon, the rearing has been developed rapidly. MolluskThere are some mollusk species in Thi Vai River which are exploited to nurture duck and fish. They shall be further studied to maintain these valuable natural resources. Terrestrial EcosystemThe local terrestrial ecosystem is characterized as follows:SpeciesCharacteristics of species in Thi Vai River are shown in Table 20.Species Coverage139 species have small coverage, sharing 53%, distributed in incident-occurred zones or used to be densely community. 86 species have average coverage, sharing 33% which are mixed groups in the community, having characteristics of dominated species. 37 species have high coverage, sharing 14%, which are dominated species in riverside forest, of which, Rhizophora apiculata is dominated. Value13 salt-water species distributed along canals, river banks in tidal inundation zones. Salt water species trees are planted or wild trees in fertilizer land along the river; 123 valuable tree species: green coverage, erosion-prevention, organic fertilizer, etc.86 species used as medical herbs; 6 vegetable species34 species as bonsai tree62 wooden tree species44 fruit tree species. Aquatic Ecosystem (Zoo and Plant Plankton, Zoo Benthos) Zoo PlanktonThe survey results of past years show that there are replacement of various species such as substitution of Cartia clausi, Paracalanus parvus and shrimp larva by Oithona plumifera and nauplius.Plant PlanktonThe survey results show there are structure variations of individuals by dominant species. When the plants were not developed in Nhon Trach III IP, algae species are dominated, including Chaetoceros, Pseudocurvicetus, C. Spinosus, Skeletonema costatum, Ditylum sol and Coscinodiscus jonessiacus. When the plants are operating, silica algae species are dominated, including Chaetoceros abnormis, Nitzchia longissima, and especially Lepto-cylindiscus danicus.Zoo BenthosThe river bed covers with gravel and stiff clay. Main zoo benthos species are Anthozoa, Spongia, Holothurian. There are Sedentaria or Terebellidesstroemi Sars, Sabllearia cenentarium Moore, Sternaspis sactata (Rosami) along the river bank. ALTERNATIVE SOLUTION STANDARDS OF ALTERNATIVE SOLUTION - Any of the alternative solutions still have to meet the national regulation QCVN 40:2011/BTNMT.- The discharge point have to ensure the discharge need, while avoid the negative impacts toward the environments and the local public. - Sludge from the treatment system has to be treated as hazardous wastes, and avoid impacts toward the environment.

This equivalent to 31.6 kg TSS, 14 kg BOD5, 104 kg COD, 0.76 kg ammonia and 0.36 kg Total ironThi Vai river water is not utilized for domestic water supply but only for waterway transport, irrigation and aquaculture among other. QCVN 08:2008/BTNMT column B2 (the National Technical Regulation on Surface Water Quality) is applied to evaluate the water quality. Polluted wastewater can cause the following impacts when it is discharged to the environment: Increase turbidity of the river flow due to SS; alter photosynthetic efficiency and reduce DO in the surface water. Suspended solid could be deposited at the outlet, altering the river flow, river depth and hydraulic conditions. Organic sludge depositing also causes oxygen deficient, forming toxic gases like H2S, CH4, etc. If the receiving source is not cleaned properly, the water will be changed to black and smelly. Increase organic pollution load (BOD5, COD), increasing organic and inorganic compound oxidization, reducing DO concentration in the water. Increase nutrients in the water (total N, total P), causing eutrophication Reduce load bearing and purifying capacity of the river. Affect to drinking and production water quality. Affect to load bearing and purifying capacity of receiving sources. As Mareng Canal is quite short (1.5 km) with small slope, and is under affected by tide, the disperse of pollutants toward downstream from Mareng is slow. Furthermore this river section also receives a 5,000 m3/day from hung Nghiep Formosa Co.Lmited, that’s why the self-mechanism is overall limited. Especially when Mareng is the only discharge road from project site toward the main river (Thi Vai)As the project treated wastewater will join other discharged sources toward Thi Vai river. That’s why the negative impacts of the project toward Thi Vai will be presented more detail in Section 4.7 “Accumulated and integrated Impacts”IMPACTS ON ENVIRONMENT AND AQUATIC ECOSYSTEM Increase turbidity, reduce DO, affecting to photosynthesis efficiency, altering number of aquatic species in the water.Impact on food chain of the ecosystem. If the river could not purified water will be polluted by organic substance and nutrients, affecting seriously to aquatic life, reducing biodiversity (species number and density), etc. narrowing habitat of small animal species in mangrove forest. Pollution of nutrients: Proper nutrient content will promote algae growing adequately in the food cycle. However, if it increases significantly eutrophication will occur, causing organic pollution. Nitrogen Impacts:+ Toxic to fish at high concentration + Small NH3 concentration and NO3- are nutrients to algae growth. + Conversion of NH4+ to NO3- needs large volume of DO. Impacts of Phosphorus: Phosphorus is an essential nutrient for algae growth. High concentration will promote algae growth. When algae died it will be organic food for bacteria, altering oxygen content, causing fish dead. Organic Substance Pollution: reduce DO, threatening to fish and other aquatic species. Impacts of wastewater discharge to mangrove forests (Long Thanh – Nhon Trach and Can Gio district) are not considered yet. IMPACTS ON HYDROLOGICAL CONDITIONSMa reng Canal flow volume is around 2 m3/s during dry season and increase to <10m3/s during flooding season. The wastewater volume of Nhon Trach 3 IP Treatment Plant is about 2,000 m3/day and night, equally to 0.023 m3/s which will not increase the water flow or the change hydraulic regime of Thi Vai River even during dry season. AIR QUALITY IMPACTS The maximum capacity of Module 2 of the wastewater treatment facility of Nhon Trach 3 IP, Phase 2 is 2.000 m3/day. They could emit odor, H2S, Hydrocarbons, Mercaptan among others affecting to areas near the outlet. However currently there is no detected odour from the Nhon Trach 3 IP Treatment Plant’s discharges, and was reflected through the surveying of residents living along Mareng Canal. Hence it can be concluded that the discharge wastewater does not affect local air quality.Obviously, the discharge from the Treatment Plant will be really small compare to Thi Vai River flowrate even during dry season (0.023 m3/s vs. 10 m3/s). So the affect toward Thi vai also minimum ACCIDENTS RISKSThe effluent is quite large at 2,000 m3/day of the treatment facility could cause river bank erosion. The large effluent may also disturb the river flow, affect small canoe navigation in the outlet area. However as the addition discharge is only 0.23 m3/s while the canoe trip record here is small, just 2-3 canoes travelling on the Canal a day, therefore the affect should be minimalSOCIO-ECONOMIC IMPACTS ON WATER SUPPLY IN UPSTREAM AND DOWNSTREAM REGIONSWastewater from the treatment facility contains organic substances (BOD5, and COD), causing turbidity increase in Thi Vai River water, offensive odor at the outlet. The effluent discharge can affect to socio-economic as follows: The discharge of treated ww into Mareng and Thi vai river more or less will impact on the economical activities of residents living along the river. However at this moment, the local government still has not received any complaints from the residents within the affected areas. The impact is analysed generally to be low considering the discharge rate of only 2,000 m3/day and ww quality meeting the QCVN 40:2011/BTNMT column B (kq=1.1; kf =1.0)CUMULATIVE IMPACTSThi Vai River is the final wastewater receiving source of Nhon Trach 3 IP. As mentioned before, the river water is not used for drinking purpose. The effluent, thus, have met TCVN 5945:2005 column B, Kq=1.1 and Kf depending on the discharge volume of the industries (pursuant to Appendix 1 of Decision No. 65/2007/QD-UBND dated December 11, 2007 of Dong Nai PC on environmental zoning for surface water basin to receive industrial wastewater. The existing effluent of Nhon Trach 3 IP Wastewater treatment facility is 152 m3/day while the permitted volume is 2,000 m3/day. Wastewater is treated in compliance with TCVN 5945:2005 column B, Kq=1.1; and Kf=1.0.At this moment, Thi vai river is the receiving body for the ww from Nhon Trach IPs (1, 2 & 3, Clothing IP), Go Dau IP (Long Thanh District), and Phu My 1 (Ba Ria –Vung Tau Province). The intake for water supply form Thi vai river is small, with slow river speed, and narrow basin. As the river is heavily affected by tides, the mixing rate of river is slow, and the flow toward the sea is small. That’s why the wastewater from Nhon Trach 3 will cause some problematic negative impacts towards the basin if is not treated properly. However, the effluent can affect to Thi Vai river water quality and flow. It also affects to aquatic ecosystem of the receiving source. The effluent is small comparing to the river flow and the wastewater is treated in compliance with Vietnam environmental standard so the impact is insignificant.To analyse the accumulated impacts of the project toward Mareng canal and Thi Vai River, we will have to analyse the discharge receiving capacity of Mareng and Thi Vai. The assessment will be based on Circular 02/2009/TT-BTNMT dated 19/3/2009 of the MONREThe wastewater of the project has to meet the national regulation on industrial discharge: QCVN 40:2011/BTNMT (column B), Kq=1.1, Kf=1.0, before being allowed to discharge into Mareng and Thi Vai Mareng Pollution Loads AnalysisMareng pollution loads can be analysed by the limits of polluting parameters in Mareng canal water.
