L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 16 / 333 CHAPTER I: PROJECT DESCRIPTION 1.1. Overview the Project 1.1.1. Project background According to the survey results implemented in 1999, the water quality in Nhieu Loc-Thi Nghe (NL-TN) canal was poor. The average concentration of BOD5 was 121 mgO2/l (while the allowable limit is 25 mgO2/l) and total Coliform was 800,000 MPN/100ml (while the allowable limit is 10,000 MPN/100ml). The pollution situation is a result of direct discharge of the untreated domestic wastewater and solid waste disposal into the canals. Due to the domestic discharge the drainage capacity of the canals will be reduced, the chance of flooding will be increased in HCMC. Based on the above, the HCMC Environmental Sanitation Projects (HCMC ESP) were developed which aim to improve the environmental quality of the Nhieu Loc- Thi Nghe canal water, which consists of two main phases: • Ho Chi Minh City Environmental Sanitation Project 1 (HCMC ESP1, from 1999 to 2012): this improves, through installation of sewerage systems and rehabilitation of the sewerage network, the pollution discharge into the Saigon River to reduce flooding and overflows in the basin. This project was completed in 2012. • Ho Chi Minh City Environmental Sanitation Project 2 (HCMC ESP 2): to construct the Nhieu Loc-Thi Nghe wastewater treatment plant (WWTP) to treat domestic sewage from selected HCMC districts and to improve the overall water quality of the Sai Gon River. The HCMC ESP 2 project is put under effectiveness since July 2015 and currently under implementation The Feasibility Study for the construction of Nhieu Loc-Thi Nghe WWTP was prepared in May 2014; the analysis considered that the capacity of the WWTP will be 480,000 m3/day until 2020 and 830,000 m3/day until 2045. Additionally, the project will include the installation of 8 km interceptor sewers from the East Bank Shaft to the planed WWTP, which will treat the sewages collected from district 1, 2, 3, 10, Phu Nhuan, Tan Binh, Binh Thanh and Go Vap. The treated sewage will be discharged into the Dong Nai River (a national waterway) with acceptable improved quality. During the prepapration, The City Environmental Sanitation Project Investment Management Agency (CESPIMA or in abbreviation IMA) prepared the environmental impact assessment (EIA) report for the project “Second Ho Chi Minh City Environmental Sanitation” in cooperation with the Meinhardt (Singapore) Ltd. The EIA report was prepared based on existing statistical data of the meteorology, hydrology, and socioeconomic conditions in the project area. Additional environmental data on air, noise, and water quality were collected from the project area and analyzed by the Institute for Environment and Resources, National University of Ho Chi Minh City. Technical manuals on process engineering, pollution control technologies (including wastewater, air emission, and solid waste) and environmental rapid assessment manuals were used in the analysis, pollution factors estimated by the World Health Organization (WHO) and other popular methods. 16 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 17 / 333 The proposed project is classified in line with the World Bank operational policy on Environmental assessment (OP 4.01) as category A project, since it is a project with significant potential impacts given the construction and operation of the WWTP and affiliated infrastructure in HCMC financed by this project. The original EIA reports on which the current document has been based on are available in both Vietnamese and English for public information. Their content has been discussed separately in a public meeting held in HCMC on April 24, 2014. The EIA report was prepared pursuant to Vietnam’s Decree No. 29/2011/ND-CP dated April 18, 2011 on strategy Environment Assessment, Environmental Impact Assessment and Environment Protection Commitment. The structure of the report followed Circular No. 26/2011/TT-BTNMT. The EIA report is also prepared taking all applicable World Bank environmental and social safeguard policies and guidelines into consideration. In accordance with the Second Ho Chi Minh City Environmental Sanitation Project (HCMCESP-2), the Nhieu Loc - Thi Nghe wastewater treatment plant (NLTN WWTP) is built at Thanh My Loi Ward, District 2. The proposed NLTN WWTP is located at the confluence of the Dong Nai river and the Saigon river. This NLTN WWTP is designed to treat raw municipal wastewater generated from the Nhieu Loc Thi Nghe Bassin (see yellow area in map bellow) and transferred from the interceptor route (see green line bellow) and generated from District 2 (see blue area in map bellow). The wastewater treatment plant (WWTP)’s outlet quality will meet the Vietnamese technical environmental regulation of QCVN 14:2008/BTNMT column A and be suitable for improvement of water quality in the Sai Gon and Dong Nai rivers. 17 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Project components HCMC ESP2 has five specific components which are summarized below (costs shown exclude VAT): • Component 1: Construction of Interceptor (Cost: US$65 million): The sewage interceptor total length of 8 km and diameter of 3.2 m will be constructed to connect sewage from East Bank Shaft to the wastewater treatment plant at Thanh My Loi ward, District 2. It will convey sewage from NLTN to the Pumping Station at the entrance of the WWTP. The construction of the interceptor will prevent the discharge of 18 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 19 / 333 untreated wastewater to the Saigon River. By now, construction of investments has been ongoing and achieved d 94% physical progress • Component 2: Construction of Wastewater Treatment Plant (Cost: US$261 million): The WWTP will treat the wastewater collected in the NLTN basin and in the D2 area. The WWTP is being designed for a capacity of 480,000 m3/day and will be constructed through a Design Build and Operate contract (DBO) where the same private company will carry out these three stages. The WWTP will be located near the confluence of the Saigon and Dong Nai rivers, and the treated wastewater will be discharged to the Dong Nai River. The site is prone to flooding and, as a result, flood protection measures are included in the project design. As reported, by Dec 2021, Physical progress of this component is less 17% - in the design and site preparation stage • Component 3: Construction of Sewerage Network in the District 2 area (Cost: US$52 million): The project will invest in drainage level 2 and level 3 in District 2. Investment objective of the drainage in District 2 is to maximize the wastewater collection to improve the environmental conditions in the project areas where untreated wastewater is discharged to water bodies. In addition, households in the project area will be connected, if they are not currently connected to the combined or separated system. The wastewater collected from the District 2 area will be transferred to the interceptor that also will convey wastewater to the wastewater treatment plant (being constructed under this project) from the Nhieu Loc-Thi Nghe (NLTN) area. By now, construction of investments has been ongoing. • Component 4: Project Implementation (Cost: US$32 million): This component has two parts: (a) Component 4a: Construction Supervision will support hiring of consultants to supervise construction during project implementation; and (b) Component 4b: Improving Sanitation Management and Project Implementation will provide technical assistance including implementation support and capacity building for key project entities (e.g., CESPIMA). In addition, support will be provided to the CESPIMA to enhance sanitation management in HCMC. • Component 5: Land Acquisition and Operating Cost of Implementation Management Agency (Cost US$40 million): CESPIMA coordinates with the People's Committee of District 2 to setup the general plan for the compensation assistance and resettlement. District 2 People's Committee is responsible for the establishment of a committee for the compensation assistance and resettlement as prescribed. The committee for the compensation assistance and resettlement will setup the land acquisition plan, documents and decisions for households, individuals, and organizations (if any) under the provisions and give land hand-over decision for CESPIMA. Component 5a: Resettlement and Land Acquisition will include costs (borne solely by HCMC) to compensate people that currently own the land where the WWTP is constructed. Component 5b: Operating Cost of the Implementation Management Agency includes salaries, fees and other costs (all borne by HCMC) for the eight years of the project implementation period. 19 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Influent Structure In the inlet structure, the incoming wastewater flow will be distributed to the pump sumps of the inlet pumping station. The water will arrive to the plant considering the connection to the last shaft 20 of the incoming interceptor DN 3200 (Package XL-01). Influent Pumping Station The Influent Pumping Station civil structure will be constructed for the 2045 horizon (55,000 m3/h). Initially, the pumping well is provided with 9 (6 duty + 3 standby) submersible pumps, each equipped with a variable-frequency drive. The capacity of each pump will be 5,900 m³/h working at 25 m.w.c. In addition, in order to provide extra protection to the inlet pumps, manual bar screens of span between bars of 150 mm has been included in the design of the well. For every two (2) pumps in operation, one (1) standby pump will be installed. The pumping station will be provided with electromagnetic flowmeters downstream the pumps. There will also be a General Bypass for the plant at the inlet of the WWTP. Whenever the water level rises over the fixed weir, the water will be conveyed to the general bypass by means of the pumps through a 2,000mm underground channel to the river. In case of emergency, or when several tanks or treatment units have to be put out of operation, redirection of the flow through the remaining treatment units will be considered and ensured. The design of the tanks and other units will be in such way, that sufficient reserved spare capacity, space and volume will be provided in order to be able to cope with the additional flow. Only in case of emergency when the aforementioned procedure is not feasible, the discharge of untreated wastewater through a separate bypass channel at the WWTP is permitted. For that purpose, a gravity bypass channel will be laid from the Inlet Pumping station to the effluent structure, where the bypassed flow will be analysed and monitored. Also, the amount of bypassed water will be measured and recorded. The bypass will be closed for normal operation by a suitable motorized penstock, which will be monitored and operated from the Scada system. Screening channels The wastewater will be pumped and discharged in a common channel that is communicated with 6 channels. (4 initial + 2 for future phase). 29 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 30 / 333 The inlet chamber will be equipped with motorised penstocks leading to the automatic bar screens with 30 mm opening. After the bar screens, fine screens with 3 mm span between bars will be installed. All the water debris automatically removed from the screens will be compacted and conveyed to a 10 m³ skip by a screw conveyor and a wash press with a capacity of 10 m³/h and a spiral diameter of 330 mm. The outlet of each channel will also be equipped with motorised sluice gates, allowing each channel to be isolated from the rest when required. The screening building civil structure will be constructed for the 2045 horizon (55,000 m3/h). Grit and grease removal Wastewater flow coming from the Screening Channels will be treated by the aerated grit removal chambers. There will be eight (8) grit and grease removal chambers (double type) prepared for the extension phase flow. Five of these grit and grease removal chambers will be equipped at present stage. The dimensions of each chamber will be 31-meter length and 4.5-m width each, total channel width of 9 m. Both grit and FOG (floating, oils and grease) will be removed by travelling bridges with suction scrapers. The grit will be conveyed to a two (1+1) 75 m³/h capacity grit classifier while the FOGs will be pumped to digestion. Every grit and grease chamber will be equipped with coarse air diffusers with a maximum flow of 6 Nm3/m3/h generate air bubbles which help separate the FOGs from the wastewater. (5W+1S) blower of 5,500 m³/h and 5.5 m.w.c of pressure will produce the air. Biological wastewater treatment - Moving Bed Biofilm Reactor (MBBR) Secondary treatment is the heart of the WWTP as it includes the biological treatment process step. Generally, secondary treatment reduces SS and BOD by a series of biological reactions (the microorganisms consume organics and nutrients in the wastewater for metabolic processes and convert it to energy, cell tissue and various gases within a specific and aerated reactor). The MBBR system consists of an activated sludge aeration system where the sludge adheres to recycled plastic carriers. These carriers have an internal large surface for optimal water, air and bacteria contact. The bacteria/activated sludge grow on the internal surface of the carriers. 30 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 31 / 333 Figure 6: Carrier The bio-carriers move freely operating in mixed motion within the aerated wastewater treatment basin. Each individual bio-carrier increases productivity by providing protected surface area to support the growth of heterotrophic and autotrophic bacteria within its cells. This high-density population of bacteria achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation. There is no need of sludge recirculation and the outlet flow is the combination of the treated water and the excess of biomass. The MBBR media will be kept in suspension to allow efficient treatment of the incoming wastewater streams and the preferred method of aeration is to use a coarse bubble aeration system that uses stainless steel piping with holes rather than conventional diffused aeration is normally adopted. Most of the biomass in the MBBR process is fixed onto the carriers, consequently the secondary clarifiers in the MBBR plant are not as heavily loaded with solids as they would be in an activated sludge plant. Whereas the clarifiers in an activated sludge plant may be mass flux limited, typically the clarifiers in an MBBR plant are settling rate limited because they receive less suspended biomass. Process efficiency per volume is much higher than that of an activated sludge due to higher biomass concentrations. 31 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Lamella clarifiers will allow the settlement of the sludge flocs with a consequently good separation between clean water and flocs of sludge. Total number of clarifiers: 8 units of 20 m diameter and 5.8 m depth. The outlet channel will collect water from all the clarifiers, from where a channel will convey water to disc filters. From the bottom of each clarifier, a pipe will drive excess sludge pumped to the biological sludge Buffer tank. Disc Filters To meet quality requirements, a tertiary filtration unit will be installed downstream of the Lamella Clarifiers. Four lines of total 24 cloth disc filtration units in a concrete basin will be installed. The discs will be arranged in parallel and each cloth disc will be formed by a structure of various segments. These segments will be used to introduce the filter panels or meshes, which will be cleaned by means of an automatic cleaning system, composed of several branches of pipes with nozzles. The filtered water will exit through the filters and will be collected in a pipe and then will go by gravity to disinfection. The disc filters are designed for micro-filtration in the tertiary treatment of urban wastewater consisting in a determined number of discs according to the flow rate to be treated. The disc filters will work completely automatically, without any auxiliary personnel and the process of filtering and cleaning the filter screens will be performed automatically. The wastewater generated from cleaning disc filters will backflow to MBBR tank. 32 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

The characteristics of the thickening tanks proposed for the average flow are the following: Number of biological sludge buffer tanks: 2 units; Width 3.9 m; Length 10.2 m; useful height 5 m Pumps will pump the sludge from the buffer tank pump thickened sludge to the digestion facility. Sludge Digestion Through the digestion process, 45% of the volatile material of the sludge is decomposed into mainly methane gas and CO2. An anaerobic Digestion System will be designed to achieve stabilization of thickened sludge. Digesters are cylindrical concrete made, with pump/nozzles mixing. The characteristics of the proposed Digester Tanks are the following: Number of units: 3 (2 on duty +1 stand by); Diameter 22 m; Cylindrical Height 21 m; Retention time 20 days; Total volume adopted: 8,000 m3 x 2 digesters. Digestion requires a series of equipment to allow feeding, discharge, intercommunication, heating, homogenisation, draining and other operations of the digesters. Several types of equipment can be considered: 34 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

For proper use, it will be necessary to reduce its moisture content and to separate all harmful compounds from it for not affecting the useful life of the equipment involved in its use. Before supplying biogas to the co-generation engines, a biogas cleaning system will be provided. The following biogas composition has been considered: 37 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

The control of the flow rate of H2O treated, as well as the pH and Rx potential of the recirculated solution, make the biological activity will be verified with very high efficiency (over 99%), obtaining as residue an effluent composed of H2O and SO4 dissolved, so that the danger of possible seals disappears. For this, a tower similar to that used in chemical processes will be used. The liquid level will be kept constant by the radar control that operates on the water inlet solenoid valve. The purge will also be automatically controlled, by means of a pH meter that acts on the corresponding solenoid valve. The main advantages can be summarized in:  No operating costs at the reagent level, since they are not required.  No cost of effluent treatment, since these can be conducted directly to the head of the treatment plant mixed with the rest of the water. 38 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

The dehumidification of biogas via cooling-condensation is an important step in the conditioning / treatment of biogas for future use as a biofuel. It will be composed by two fundamental elements: cooling / chiller machine and heat exchanger / condense where a moisture value below 50% of biogas is obtained. We propose two lines of 400 Nm³/h capacity each. • Gas Flare In the event that gas production was greater than the gas consumption, and in case gas holders were full, excess gas will be burnt at the gas flare provided. The gas flare capacity will be 500 Nm³/h, enough to burn the maximum gas production, and will start and stop depending on the gas holders levels. We propose to install a hidden flame gas flare, provided with an automatic system to ensure the flare will work. The gas pipeline that connects the biogas network with the gas flare will have the following items:  Butterfly valve  Flame arrestor  Odor treatment To prevent odour within the plant site and surrounding areas, it is necessary to build three deodorization stations, two for the water line: beside the Influent Pumping Station and another one at the Screening Building; and the third one for sludge treatment line, near the Sludge Building.

The main platform works  Site Clearance: Site clearance to be applied only for entire plant area including Phase 2 and green space. This means: - 141,000 m² for WWTP footprint Phase 1 and Phase 2. - 1,478 m2 for the landside and river dyke sides. According to the AVJ-A000-EN-RPT-0001 Flora Survey Report there are no protected species at site. Trees above 10 meters will be identified however none are in the list of shade trees defined in Circular 20/2005/TTBXD therefore they will be removed if located at the WWTP footprint area. Tree above 10 meters located in phase 1 but out of the plant footprint will be analyzed one by one as they may interfere with traffic on site, networks or generate shade for solar panels. In any of these interferences, they will be removed. Trees above 10 meters located in phase 2 will be maintained. At the area not or less impacted by the high tide, the site clearance will be done using workers and classic equipment such as excavators directly on the ground. Monitoring of tide will be made daily. Work from ground area will be stopped when flooding level will be reach and equipment will be transferred in dry area near the Vo Chi Cong road. When tide level is high, or in areas permanently flooded, this activity will be performed by barges equipped with excavators. This solution will be the most used, barges will move through the existing canals on site. Big and high tree will be cut manually by workers from the same barges. The vegetation will be temporary stored on site then it will be transported to the approved landfill. During the cutting of the big trees, it must be taken in account the entanglement of trees in order to define the safety distance from the constraints observed and to allow only the persons/manpower especially trained and focusing on this job. All vegetation waste will be transported by truck and disposed at Binh Duong landfill.  Topsoil Removal: Topsoil removal will only be performed on WWTP Phase 1 footprint of 112,957 m2. Barges and excavators are used for topsoil removal. The bottom level of the natural platform will be regularly checked with a survey equipment in order to control the operator to reach the good level. Removed topsoil will be loaded on barges and reused for: - Filling some small streams linked to the existing Phu-My creek, - Banking up the boundary dams around the phase 1 to support the platform sand backfilling, - Landscaping. 59 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Creek relocation Figure 15: General layout of creek relocation  Hydraulic Study for creek relocation work: At the wastewater treatment plant area (38 ha) there are 3 creeks namely, (i) Phu My creek (47.5 m3/s; 4.5 m depth and 50 m wide); (ii) Ngon Ngay (no flow, primarily mud of 1 m depth and 12 m wide), and (iii) Ky Ha creek (65 m3/s; 5.5 m depth and 40 m wide). As part of the preliminary works, the existing Phu My creek running across the site from North to South will be relocated to take full possession of the Site. This relocation was also required in order to fit the WWTP in the original Feasibility Study. Thus, at the North end of the site, the Phu My creek is rerouted into the existing Ngon Ngay river (Figure 9) via a newly constructed section of Phu My canal (Figure 9, light blue colour). This new canal is excavated by excavator on barge (please refer to Figure 11). Existing Ngon Ngay canal is dredged to expand to bed = 20m, depth is -3.5 m and satisfy the flow capacity of Phu My creek after its relocation. Dredging is performed with pumping boat and excavator on barge (please refer to Figure 11). Approximately 105,000 m³ of mud will be moved to the barge by excavator and then, dredged mud will be nominated the parameters for testing, number of samples, and VietNam standard reference by Employer/DONRE according to Decision 44-2015-UBND HCM, therefore the Contractor will temporarily store it at the approved site area for re-using it later. 68 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 69 / 333 A hydraulic study has been performed as part of the design and shows that the Ngon Ngay canal absolutely satisfies the water drainage capacity of both Phu My creek and Ngon Ngay river. The water level values calculated in this report are based on the hydrological elevation system (the old elevation system 1983) and based on the experience of flood and tide control projects implemented for Ho Chi Minh City, then when calculating the design according to the national elevation system (Hon Dau - 2008 elevation system), the difference between the old and new elevation systems is 23.0cm. With the result of calculating the maximum water level based on national elevation (Hon Dau elevation system) in the project area considering climate change till 2050 is: +2.14m+0.23m= + 2.37m and 2100 is: 2.50m+0.23m = + 2.73m. According to Decision No. 6707/QD-UBND, dated on 29/12/2012 about approving the adjustment of general construction planning of District 2 till 2020, scale 1/5,000; "Control elevation: the area inside the dyke + 2.00m, the area outside the dyke is + 2.50m" The platform leveling area is entirely located within the flood protection dyke line), so elevation for platform leveling + 2.50m is completely suitable with the approved planning and to ensure the technical requirements. In order to satisfy the waterway traffic on Ngon Ngay canal after dredging is completed, calculation results show that the size of the canal depends mainly on the navigation requirement, the size of the diversion canal and the dredging canal have the width Bed = 20m, the elevation of the canal bed = -3.5 m which were approved in the basic design. The width of the canal surface will depend on the excavated slope and the dyke line arrangement to protect the project work and will be accurately determined based on the calculation of the canal slope stability with the bed elevation of -3.50 m. Hydraulic calculation results show that in the future when the project area (including Phu My river) is filled and the entire surrounding project area is implemented and the dredging canal is widened, the flow velocity in the Phu My and Ngon Ngay canals will decrease compared to the current situation in Phu My creek and Ngon Ngay river, meaning that the erosion will be reduced compared to the current situation. Currently, the left bank line of Ngon Ngay canal is not eroded, so no reinforcement protection is required. When dredging the Ngon Ngay canal to the bottom elevation of -3.50m, the detailed design defined a 1:3 slope coefficient to ensure overall stability. Figure 16: Typical section of new Ngon Ngay canal The simulation results of siltation for general project site and the adjacent areas show that after building the project and dredging the new canal, the flow regime at the site will be moderate, there are no significant changes, 69 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 70 / 333 the main trend is siltation due to small velocity causing siltation. Due to the impact of the new diversion canal, the flow velocity in the Ky Ha river decreases with about 0.3 - 0.5 m/s velocity; sedimentation will occur at a very low rate, only about 1-2 cm / year. About 300m upstream of Ky Ha river outside the project site, the rate of siltation and erosion will be quite small since the velocity and discharge will have decreased. The topography in the middle of the channel will not have significant changes, on both sides the erosion rate will be of 2-4cm/ year. After backfilling platform and surround areas are completed as planned, the ground elevation is almost higher than the tide peak level therefore the water flows in rivers and canals system do not overflowing to riverbank. It leads to the rivers flow in the area is decreased significantly. Discharge flow in the Phu My River decreased from 29. 14 m3/s to 2.57 m3/s, the flow in Ky Ha river decreases from 61 m3/s to 47.60 m3/s. For Ngon Ngay canal after dredging, it increases from 8.22 m3/s to 12.65 m3/s. Hence, Ky Ha completely receive the flow of Phu My river after diversifying  Dredging work: The dredging work will be conducted on Ky Ha river (Km0+00 to Km0+600), Ngon Ngay river (Km0+600 to Km1+140) and Phu My diverted section (Km1+140 to Km1+300). The volume of soil dredging is approximately 105.000 m3. The massive volume has from Km0+600 to Km1+300 approximately 97.800 m3. The remaining volume has from Km0+000 to Km0+600 approximately 6.800 m3. The maximum capacity of pumping boat is 2.400 m3 per day (including mud and water with ratio mud/water=1/3). Width of riverbed is 20m, depth is -3.5m ASL. The dredging work will be conducted according to the sequences as follows: - Step 1: Open stream excavating from Km0+600 to Km1+140 (Ngon Ngay river) The subcontractor will arrange two workshops start from Km0+600 and Km1+140 and excavating come together from two of direction. - Step 2: Temporary dam for closing the open stream at Km0+600 and Km1+140 After finishing the open stream works, the 2 remaining workshop with 4 pumping boat will go into the stream from two of direction at Km0+600 and Km1+140. After that the stream will be closed at Km0+600 and Km1+140 by temporary berm at high tide time (+1.5m ASL) in oder to keep and maintain the height of water table has more than 1m. The elevation of temporary dam will be +2m ASL, the length of temporary dam will be made enough in order to control the water level in the stream and to avoid the mud overflow the watercourse as well. The temporary dam at the Km0+600 will be installed 8 uPVC D250 pipe at the cote +0.0 in order to supplement the water during the dredging process. Each head of piping will be install top hinged flaps in order to prevent and seal against backflow. After finishing the installation of the uPVC D250, the temporary dam will be embanked and close. 70 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

At the area from Km0+000 to Km0+600 and Km1+140 to Km1+300 (Phu My diversion section) will be arranged one workshop for dredging. The mud after dredging in these sections will be placed on the barge when the container has full it will move to section Km0+600- Km1+140. The mud will be transferred to the storage area by pumping boat. Section Km0+000 to Km0+600 (Ky Ha river), riverbed will be dredged to -0.2 m (ASL), from prevention flood dyke to 18-20m wide to make gabion coated PVC thick 30cm. This gabion mattress is an erosion-proof reinforcement structure for a flood retaining wall. The crank net will be applied to minimize turbidity and sedimentation on Ky Ha river during dredging process. At the area from Km0+600 to Km1+140, the soil will be excavated and discharge at the pumping boat location and then the mud will be pumped to the stockpile area. - Step 4: Removal the boundary dam After finishing the dredging works at the section from Km0+000 to Km1+140, the temporary berm at the stream will be removed by excavator then the soil will be transferred to the stockpile area by pumping boat. - Step 5: Finish and inspection Figure 17: Principle of excavator and pump boat on the barge for dredging works.  Existing Phu-My river backfilling works: The backfilling of the Phu-My river will be started after dredging of Ngon Ngay canal is completed. Then concrete sheet piles will be installed North and South of the existing Phu My river (i.e., North and South closure dykes). The filling of existing Phu My creek will be done up to ground level (average elevation +1,0 m ASL). The approximate quantity of Backfill for sand will be about 60,000 m3. 71 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 76 / 333 o The total length of each individual pile is 24 to 30m (variable depending on the size and loads from the building). The piles will therefore need 2 segments of 12 to 15m each. o The 1st pile segment will be lifted by the piling rig, positioned and pressed (or driven) into the ground. o When the top of the 1st pile segment will be 1m over the sand platform, the driving/pressing will be stopped. The second segment will be installed on the top of the 1st segment and the joint will be welded. o The driving/pressing of the 2nd segment will continue once the welding is completed and inspected. o In case the head of the pile elevation is lower than the platform elevation, a special steel extension will be used to push the pile at the required elevation. o During the works, the lowering of piles will be continuously monitored in log. During PHC Pilling, no considerable excavated material will be formed because PHC piles are pressed into the ground. Bored piles The bored piles will be required for the Sludge Digesters. Each digester will require 61 piles of 36m long and 800mm of diameter. The execution of the works will be carried out as follows: 1 2 3 4 5 6 Figure 21: Execution steps of bored piles 76 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Setting out and site preparation Prior starting the works, the working platform shall be improved in order to withstand the load of the equipment. This platform will be done as follows: • Compaction of the sand platform • Leveling and compaction of crushed stone • Additional steel plates will be installed under the crawlers of the cranes as needed to reduce the applied pressure to the ground within acceptable levels. After the work platform is completed, setting out of the pile will be done and the steel casing will be driven into the ground on 1-2m prior stating the excavation. 2. Excavation of the soft ground layer (layer 1) Due to the soil characteristics of the layer 1, while drilling the pile, the steel casing will be simultaneously pushed into the ground till passing the layer 1: on a depth of approx. 10-12m. This steel casing has as objective avoid any collapse of the soft ground during the excavation and will be removed at the end of the pile construction process. Additionally, drilling fluids will be required to avoid any instability of the borehole during the drilling. The drilling fluids are usually bentonite, which the proceed is described further on the point 3 below. 3. Excavation with drilling fluid Once the layer 1 of soft soil is passed, the excavation will be carried out without steel casing. The stability of the excavation will be done using a drilling fluid to support the borehole wall. The drilling fluid will be recycled in a specialized treatment plant. The mucking materials (about 4000 m3) will be placed directly into a dump truck standing alongside the excavation workshop. The excavated material will then be transported to a temporary storage area on-site where the muck will have time to drain. Once drained, the mucking material will be loaded and transported to a licensed disposal landfill or designated area. Excavated material (estimated about 4000 m3) will be monitored following regulations. The samples will be taken for analysis. If meet requirements, it will be disposed in the internal disposal area. If not, it will be transported to Da Phuoc Landfill. Bentonite mixed with water will be used as excavation supporting fluid. The bentonite slurry will be mixed on-site and stored in tanks. The supporting fluids shall be in accordance with TCVN 9395: 2012. The bentonite slurry will be recycled: • After mixing, the bentonite slurry will be stored in fresh fluid tanks • After being used during the excavation process, the bentonite will be treated and recycled in special plants and stored in tank for recycled bentonite. 77 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Reinforcement works Reinforcement pre-assembly will be carried out on site on a dedicated area. Once the drilling is completed, the rebar cage will be lifted with a crane and introduced into the borehole still filled with bentonite. 5. Concreting Works The concrete will be placed with designed hooper with pipes bringing the concrete directly at the bottom pile. During the concreting works, pouring of concrete will be monitored ensuring that the pipe is continuously embedment 1.5m into the concrete. While filling the borepile with concrete, the bentonite slurry shall be pumped back into the bentonite treatment plant. Concrete pouring shall stop as minimum about 1.5m higher than the cutting height of the pile (to exclude the concrete and drilling solution when constructing the pile). 6. Removal of the temporary steel casing At the end the concreting works, prior the concrete sets completely, the temporary casing will be removed and reused for other piles. Bored piles in numbers: • 3 tanks with 61 piles of 36m long with a nominal diameter of 800mm • 6588 linear meters of drilling • 3311 m³ of concrete B40 • 555 t of rebar Diaphragm Walls or D-Walls The Diaphragm Wall is the external wall of the Influent Pumping Station and which will act as the foundation of the structure. This D-Wall has a thickness of 1200 mm and around 40 meters deep, approximately 70m length, from the existing platform and its bottom considered at -37.5 m ASL. The execution of the works will be carried out as follows: 78 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

This platform will be done as follows: • Leveling and compaction of the sand platform • Spreading of a geotextile • Leveling and compaction of crushed stone on a thickness of 50mm • Additional steel plates will be installed under the crawlers of the cranes as needed to reduce the applied pressure to the ground within acceptable levels. After the work platform is completed, a cast in-situ guide wall will be built out of reinforced concrete. The guide walls shall be used as the initial method for achieving the construction tolerances of the head of the D- Wall. The walls will not be less than 20 cm thick and distance between the two panels will take in consideration a sufficient slack from the design with of D-wall panel. 79 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

The excavation will be carried out by specialized cranes equipped with a hydraulic clamshell bucket. The stability of the trench during excavation will be maintained at all times by using a stabilizing support fluid supplied via pipes from an on-site plant. The stabilizing support fluid will be recycled in a specialize treatment plant. The excavation verticality and depth will be monitored using an on-board computer and type Enpafraise/Jean-Lutz software or equivalent. The mucking materials(about 4500m3) will be placed directly into a dump truck standing alongside the excavation workshop. The excavated material will then be transported to a temporary storage area where the muck will have time to dr ain. Once drained, the mucking material will be loaded and transported to a licensed disposal landfill or designated area. Excavated material ( estimated about 4500 m3) will be monitored following regulations. The samples will be taken for analysis. If meet requirements, it will be disposed in the internal disposal area.

The concrete will be supplied via a ready mixed concrete company whose batching plant will be close to the project. The concreting shall be continuous to avoid any cold joint. The concrete will be placed with designed an adapted pouring hooper with pipes brining the concrete directly at the bottom of the D-Wall. During the concreting works, the pouring will be monitored in order to ensure that the pouring pipe is continuously embedded 1.5m into the concrete. This is required to avoid mixing the concrete with the bentonite during the filling process of the D-wall with the concrete. While filling the D-Wall with concrete, the bentonite slurry shall be pumped back into the bentonite treatment plant. Overflow of bentonite out of the excavation shall be avoided to aovid hazardeous working conditions.

L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 85 / 333 Description of the Deep Cement Mixing (CDM): Mechanical soil mixing is performed using single or multiple shafts of augers and mixing paddles. The auger is slowly rotated into the ground. Cement slurry is pumped through the hollow stem of the shaft(s) feeding out at the tip of the auger as the auger advances. Mixing paddles are arrayed along the shaft above the auger to provide mixing and blending of the slurry and soil. Slurry lubricates the tool and assists in the breaking up of the soil into smaller pieces. A continuous soil mix wall is constructed by overlapping adjacent soil mix elements. Soil mix sections are constructed in an alternating sequence; primary elements are formed `rst and secondary elements following, once the `rst have gained suf`cient strength. The CDM has the following advantages: • Safe construction: CDM implementation requires a very limiter interaction of the drilling equipment with labor compared to other similar solution. • Environment-friendly: minimizes vibration, reducing construction noise, less exhaust fumes. Does not generate excavated materials by using the soil as part of the retaining wall structure. Finally, if a low carbon cement is used, the carbon impact of this solution is very low. CDM or Soil Mixing Wall (SMW) is used to mix cement slurry with soil in situ to create a cohesive soil block. Strength of mixed soil is variable and tailored according to project requirements and site conditions. Quantities: • A total of approx. 68000 lm of CDM will be required for the implemation of 603 linear meter (ln) of finished retaining walls around the MBBR-Lamella clarifiers Figure 32: Example of a Deep Cement Mixing equipment (right) and detail of the mixing rods (left) 85 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Earthworks quantities are the following: - 91,246m³ for mass excavation of the WWTP buildings (out which 58,376m³ will be sand and 32,870m³ will be soil of layer 1). Those excavations are planned to be carried out by specialized earthworks companies. On the sketch below, the layout of the main excavations: • Highlighted in orange are shown the deep excavation with retaining walls (7 m depth) • In red the deep excavation done for the Influent Pumping Station inside the D-walls (20 m depth) • In blue, the shallow excavations (1m) 86 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 87 / 333 Figure 34: Layout of the excavation for the buildings The excavation of the networks will be treated separately since the excavation sequence is specific to the construction process of laying the networks. The excavation will be done on the sand platform; therefore, no fauna or flora is to be expected. The deep excavation will require dewatering works. The pumped water shall be disposed directly into the sedimentation ponds constructed for the preliminary works. Hydraulic excavators ranging from 20 to 40t will be the main tool for the excavation works. The expected excavated materials are the follows: • Sand: used for the project platform. • Natural soil of layer 1: very soft high plasticity silts, slightly organic to organic (MH/OH). The bottom level of the excavations will be regularly checked with a survey equipment in order to control the operator to reach the good level. The excavation will be carried out by layers in order not to mix the materials. The sand will be kept on site and reused for the filling works: • Backfilling of the old Phy My River (after completing the closure) • Backfill around the buildings • Final leveling of the platform prior commencement of the landscaping works. This will allow to reduce the carbon impact by not having to transport the sand to disposal areas or then mobilize new material to the site. 87 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Civil Structure or Concrete Structure Most of the buildings are done out of reinforced in-situ concrete. The overall construction process of all the buildings is similar and will be carried out as follows: • Ground leveling and compaction • Blinding Concrete: o Excavation of pile caps, pits 88 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

The water test is one of the mandatory tests for the final acceptance of the structure. Test will be carried out as follows: o Before conducting the water test, a visual inspection of the concrete wall will be carried out. o The identified irregularities on the concrete surface, which could compromise the watertightness, shall be corrected. o The water test shall be done individually for each chamber. The SUB shall propose a water test sequence where 2 adjacent rooms or structures cannot be tests simultaneously: chambers adjacent to the chamber under test shall be empty during the test. Backfilling around concrete structures for retaining aqueous liquids is only permitted to start once the water tightness test has been carried out to the full satisfaction of the project requirements. Criteria of acceptance of the test is as follows: Table 8: Water test criteria o Notwithstanding the satisfactory completion of the above test, any leakage visible on the outside faces of the structure shall be stopped. o On satisfactory completion of the test, the structure shall be emptied as far as practicable, unless the water can be used as part of subsequent activities. o In order to avoid using clean industrial water for the test, the Contactor intents to use the river water. • Backfilling After completing the civil works and water test, the backfilling around the structure till the sand platform elevation will be carried out. As mentioned, the sand of the excavation of the buildings and stored on the site will be reused for the backfilling works. Below, is described the backfilling works around the concrete structures: o The sand shall be placed in layers, not exceeding 500mm in depth. o Compaction shall be carried out making sure there is no accumulation of water. 98 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 99 / 333 o The moisture content of the backfill has to be adjusted to an optimum either by drying out or by adding water. After such treatment, the backfill shall be thoroughly mixed until the moisture content is uniform. o Each layer shall be tested prior continuing with the backfilling of the next layer. The Backfilling acceptance criteria is as follows:  All compaction tests protocols, together with a survey confirming the proper elevations layer, shall be proposed to the CTR for review and approval.  If, the compaction backfill layers have densities below the specified limits, the SUB shall provide additional compaction and testing until reaching satisfactory results at his own expense.  The compaction acceptance criteria are as follows: Table 9: Compaction criteria  Structural Works of the Buildings: Metal Structure The metal structure will be erected after completion of the concrete structures. The steel erection will be done in the following order: o Installation of the anchor bolts o Erection of the vertical steel columns o Erection of the beams o Installation of cladding as needed • Installation of the anchor bolts During the construction of the civil structure, box outs will be implemented in the lactation where the anchor bolts shall be installed. 99 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Those works will be carried out with cherry picker and crane. The crane will lift and put into position the cladding panel. With cherry pickers (or alternatively with scaffolding), the workers will access the cladding panel, adjust it into position and fix it to the steel structure with self-tapping screws. b. MEP and Architecture The construction activities will mainly focus on installation of pipe system with pipe laying. Mechanical and Electrical equipment will be erected by cranes or cheery pickers. Pipe laying works are including the following steps: • Site preparation • Pipe alignment • Digging and Excavation • Sand bedding • Pipe handling and storage • Excavation and soil removal • Implementation of work Site preparation Supervisor shall arrange safety fence, barrier, traffic control signboard, project information signboard and traffic controller/flag persons along the road to prevent people to access the site before start of digging and installing. Survey will be carried out using Total Station Survey method along lines where new pipes are to be laid and as required for providing connections. The level will be taken at regular intervals (20m) for longitudinal section and will include points of change of gradients such as soffit and invert levels of culverts, road crossings, etc. The levels will be determined with reference to bench marks established by the accepted country surveys. Detailed profile drawings will be produced to detail the specials: manholes, bends, tees and eventual changes of the vertical and horizontal profile. 102 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Pegs will be placed where fittings, valves etc. are required. 103 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 104 / 333 Levels will be taken at the natural ground level of the pipe centreline using temporary bench-marks. A pipe profile will be drawn showing the pipeline invert relative to the ground levels. The pipe profiles will be submitted for approval prior to excavation work commencing. The pipes will be placed along the trench in order to minimize the handling during the pipe laying works. Digging and Excavation When all equipment and materials are prepared then the excavator can start trenching. Foreman and surveyor shall check depth and slopes of trench frequently for accuracy according to approved shop drawings. For deep excavations, support structures will be implemented as needed. Selected excavated sand must be keep near the trench with estimated excavated material is about 40.000 m3. Sand bedding After the appropriate depth of trench is reached the site supervisor shall prepare for sand bedding. Sand bedding should be well compacted with plate compactor or tamper and will completely fill the whole width of the trench making sure there are no sharp objects or stone that could scrape or puncture the pipe. Pipe handling and storage All material will be transported from the stockyard to the work area with cargo crane truck then kept to one side of the trench or sent directly into the trench if sand bedding is ready. Pipes and fittings will be stored on side and Special caution will be made to avoid damages during transport and storage. Excavation and soil removal During the excavation, the sand of the platfrom and the natural soil will be segregated. While excavating, dump truck will be positioned parallel to trench in front of excavator to be able to load soil for transfer to internal disposal area or lawdown area. Sand will be reused for the backfilling after completing the network installation. Implementation of work In order to meet the Project deadlines, one to two pipe laying crews will be working at the same time. They will be organized as follow in order to optimize the pipe laying ratio:  Along the main road or secondary road: excavator will excavate and fill trucks located behind in order to minimize the traffic disturbance, one labourer will be dedicated to the pedestrian protection in the vicinity of the excavator and a second one will guide the excavator driver – Please refer to the procedure for Traffic Management,  Supervisor will ensure that the pipe is laid at the right elevation as indicated in the pipe profile and gradient using topographic level,  Pipe layers and labourers will ensure that the bedding is correctly placed and compacted before backfilling the trench – see drawings hereunder, 104 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 105 / 333  When backfilling takes place on land (riverbed, open field…), existing sand will be used as backfill. Compaction will be done by layer depending on the nature of the material and surface will be restored as existing (topsoil, boulders…).  Architecture The finishing materials will be applied through painting, coating and mostly done by manual handling. The surface materials are mainly water paint.. Decoration form will be simple and suitable to the overall landscape. c. Networks, Roads and Landscaping  Networks For the pipeline network connecting between buildings, the method statement of installation is the same as in MEP section. Mechanical and electrical network will be installed with help of crane, cherry pickers and manual handling.  Road and transport system The work sequence of sub-base and base construction is depicted by the following flow-chart. 105 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Any debris, unwanted material, weak spots and potholes should be removed before site inspection. Prior to spreading sub-base materials, the width and level of sub base should be indicated at site clearly based on approved working drawings. And also access road for material supply and safety traffic indications shall be prepared so not to affect existing traffic condition. Typical Cross Section Sub Base Thickness Sub Grade Design Width 2) Material Delivery and Spreading Material will be delivered directly from source approved by Engineer after accepted inspection for sub grade. During handling and loading, the material shall be kept in its original condition to minimize segregation degree and loss. It shall be desirable to be covered by sheet for delivery truck to minimize loss of moisture, fine particles, dust and material spillage. Prior to delivery, materials should be tested at the source of supply to ensure that they satisfy the specified grading and other physical properties. When delivered at site, sample should be taken for testing to ensure it is same proposed material or not in accordance to the approved frequency. Sub Base shall be spread with 20cm per layer for compaction. Spread aggregate shall be made uniform level by motor grader to obtain the compaction degree of 100% of maximum dry density. In case of over size of at least 50mm delivered, worker will sort out them by manpower. Water shall be sprinkled around construction area as well as spread sub-base materials to minimize environmental dust impact.

L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 108 / 333 3) Compaction After spreading of materials, it is important to make the aggregate with smooth surface for easy compaction of the Sub-base layer. Site check of smoothness for leveling will be carried out by subcontractor at each stakes whether to be enough the design thickness or not. Workers will adjust the thickness of sub-base by manpower at edge of aggregate and nearby structural area and etc. Compaction should be carry out immediately after spreading of aggregate. Compaction is to be achieved by vibrating smooth steel wheel rollers. If the moisture content of the material is too low for effective compaction, water may need to be added, using the water tank. As rolling proceeds, grading should take place as necessary to fill any low spots, to remove any unwanted material, and to ensure that the finished sub-base has the correct shape. Compaction usually begins at the low side of the sub-base and progresses to the high side. Rollers should move parallel to the center line of the pavement, and each pass should uniformly overlap the preceding pass. All sections of the sub-base should be given a uniform number of passes or coverage. All spread material should be sufficiently compacted as soon as possible so that water will not penetrate it when it will rain. Each compacted layer should be tested for density to ensure that the desired compaction has been achieved. In addition, if desired, proof or test rolling with a heavy roller shall be carried out to detect any weak areas. After compaction, the surface of the layer should be kept in good condition until the next layer above is placed. In general, the next layer should be placed as soon as possible. If the surface of a layer of sub-base/base becomes smooth or slick, it may be necessary to lightly tine or roughen the top of it before placing the next layer, to ensure effective bonding between two layers.

Geotechnical Conditions At the site location, soil condition is made of thick layers of Quaternary sandy, silty and clayey sediments. Bedrock (mudstone) is only encountered at great depths (more than 100 m deep). This is the typical soil condition of the Ho Chi Minh City region. Under a superficial layer of very soft to soft clays with thickness varying from 9.5m up to 12.5m, layers of stiff to very stiff clays and medium dense to dense sand are encountered. 142 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Topography and Water Levels Ground level in the Site is variable between around +1.8 m and +/-0.0 m. The topographical levels of the existing soil are given by the drawing AVJ-A000-SW-DWG-0001 “Project Topographical and Bathymetric survey plan” Drawing AVJ-A000-SW-DWG-0001 “Project Topographical and Bathymetric survey map” is based on the topographical and bathymetric survey carried by Contractor between February and May 2020. This drawing will be considered as the reference for the execution needs for site clearance and sand backfill of the platforms. The site is crossed by a +/- 30 m wide river (Phu My River), which riverbed lies at elevations ranging between -2 m ASL and -3.5m ASL. As the site is surrounded by rivers (Saigon river and Dong Nai river), the groundwater level is influenced by the water levels in these rivers due to low and high tide phenomenon, with significant amplitude from around -1.5 m ASL up to +1.5 m ASL, based on the Hydrological survey carried out by the Contractor from February and March 2020. However, based on a longer duration study, as per the bidding documents, this amplitude may vary from -2.7 m ASL and +1.7 m ASL. 143 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

The timetable of these low and high tides ranges from about one hour to a day compared to the following one. 144 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 145 / 333 3.3. Hydrological Characteristics Over the time, the flow regime also has a deep divergence and forms two opposing flood-dry seasons. According to the common seasonal division criteria, the flood season on most of the Dong Nai river basin begins at about June, July, which means that it occurs 1-2 months after the rainy season, due to the losses after a prolonged severe dry season. Simultaneously with the end of rainfall, the rivers and streams in the region also ended the flood season around November. Thus, the flood season is lasted for 5-6 months. In the dry season, due to the water source from the upstream is small, the tide is most affected, the water level on the river depends mainly on tidal fluctuations. Due to the tidal energy reduction, the tidal peak water level decreases gradually along the river. In the flood season, due to the upstream discharge increases, the general trend is that the peak water level decreases gradually from upstream to downstream. The highest peak water level every year usually appears in December and January in coastal areas. About from June to August is not only the time when the lowest tide foot water level often appears in the year but this is also the period for the lowest average water level. Therefore, from June to August is the most favorable drainage time for the year, giving us some basic water level characteristics of the main locations. The project area is in Thanh My Loi ward, District 2, Ho Chi Minh City. There are 3 main rivers in the project area: Phu My canal, Ngon Ngay canal and Ky Ha canal. Phu My canal is a 2.5km long dead-end river, the river is very curved. Ky Ha canal, the section flows in the project site has flat river bed and relative stable canal with 40m wide. Ngon ngay canal is about 700m long connecting Phu My canal with Ky Ha canal, the river bed is about 12m wide. The flow regime on all three rivers is directly dependent on the tidal regime of the lower part of the Saigon Dong Nai River. With the current topographical conditions, to calculate with 10% rain and tidal conditions, then the maximum water level in the project area is 1.58 m. The maximum water level in Ky Ha, Phu My, Ngon Ngay branches is similar to 1.58 m. For Ngon Ngay canal, due to the topography bed is higher than the rest of the river branches, then when the tide comes down and the low tide time in this area, it will have a period without water, the smallest water level is -0.23 cm. Because the Ky Ha and Phu My rivers are the two major tributaries, directly transporting water in the project area, the velocity of the flows in these two branches is the largest of which the maximum velocity in the Ky Ha River is 0.66 m/s; the maximum velocity in Phu My is 0.64 m/s; the lower velocity at Ngon Ngay is 0.32 m/s. The discharge flows in the respective tributaries is 5.85 m³/s at the section M4 - Ngon Ngay; 49.43 m³/s at section M8 - Phu My; 75.85 m³/s at section M7 - Ky Ha. 3.4.

Beside, some canal branch: Cho Dem, Go Cong, Thay Cai -An Ha, Tra in suburb, though has big flow, but the water quality is not stable because of manufacturing and domestic wastewater, so it just only can be used irrgation and drainage, aquaculture. Besides, the area of Nha Be river, though has high flow, but poor quality, salinity highly, so can't use directly for life activities purpose. Perhaps, at the area of Dong Nai river (near Ba San island- river branch, provincial line between Dong Nai province and HCM city, and the area near Tac river -Dist 9, because of limit of water supply capacity and the water source be effected with alum, so some households live in the riverside still use the river water directly (after finish the preliminary treatment). Besides, the area next to Sai Gon river, near Hoa Phu pump station also be used for life. Hence, the main water supply for HCM city is Sai Gon and Dong Nai rivers, in there Tan Hiep water plant get water from Hoa Phu pump station (Cu Chi Dist) on Sai Gon River. Thu Duc water plant get water from Hoa An station on Dong Nai River. But the quality of these 2 rivers are at alarm level because of wastewater from upper of Sai Gon river ( in Binh Duong, Tay Ninh province), and upper of Dong Nai river (Binh Duong, Dong Nai province), besides, be affected by wastewater at the lower ( HCM city, Binh Duong) of 2 rivers follow the tide in, affect to water supply station. The wastewater out area, located in buffer zone belong to the basin of Sai Gon - Dong Nai river.

In fact, the area that needs to be cleared from vegetation is approximately 15 hectares of the total 38 hectares hand-overed by the Employer. This field was used in the past primarily for agricultural, residential or cemetery purposes. Currently, this area is covered by randomly grown vegetation (e.g., shrubs, small bushes, nypa trees); three creeks (Phu My, Ngon Ngay, Ky Ha) and ditches, all of that give the area the characteristics of shrub swamp conditions. The overall area is more or less flat but partially flooded during high tide. Consequently, there are no secular trees in this area. Moreover, in term of precious and rare trees, a comparison with the list of Endangered, precious and rare species of forest flora in Appendix 1 of Decree 06/2019/ND-CP has been done and none of the existing plant categories on site belongs to these lists (Group IA and Group IIA – Appendix 1 of Decree 06/2019/ND-CP). Moreover, according to Point c, d, Clause 2, Article 14 of Decree 64/2010 / ND-CP Management of Urban green trees, since there is not shade tree with a height of over 10m or a conservation tree in the project area, no specific permission from the Authority is required before carrying out felling or relocation. On the other hand, the project area is located in a city area, and not in the wildlife conservation area. Only local and common fishes live in the river with some kind of eels and frogs living inside vegetation area.

Technological features of Biological reactors - Moving Bed Biofilm Reactor (MBBR) under QCVN 14-2008 Secondary treatment is the heart of the WWTP as it includes the biological treatment process step. Generally, secondary treatment reduces SS and BOD by a series of biological reactions (the microorganisms consume organics and nutrients in the wastewater for metabolic processes and convert it to energy, cell tissue and various gases within a specific and aerated reactor. The MBBR system consists of an activated sludge aeration system where the sludge adheres to recycled plastic carriers or bio-carriers. These carriers have an internal large surface for optimal water, air and bacteria contact. The bacteria/activated sludge grow on the internal surface of the carriers. 176 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND SOCIAL MANAGEMENT Rev.

Each individual bio-carrier increase productivity through providing protected surface area to support the growth of heterotrophic and autotrophic bacteria within its cells. This high-density population of bacteria achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation. There is no need of sludge recirculation and the outlet flow is the combination of the treated water and the excess of biomass. Bio-carriers are kept within the reactors by a sieve arrangement at the reactor outlet.

L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 189 / 333 CHAPTER 5: ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT 5.1 Impacts Assessment 5.1.1 Positive impacts Wastewater of the entire NLTN basin and District 2 will be treated to meet the quality stipulated in National Technical Regulation QCVN 14:2008/BTNMT column A, before being discharged into the environment. This will reduce the risk of pollution in ground water, soil environment, air environment and overall Sai Gon river ecosystem (Source: Environmental Impact Assessment report – Ho Chi Minh city Environmental Sanitation Project – Phase 2 in Sept 2014 is attached in the bidding documents). The social impact assessment confirms that the overall social impact of the project is positive - because the project will improve the environmental sanitation for the two target catchment areas - Nhieu Loc – Thi Nghe area (Phase 1) and District 2 area (Phase 2). Specifically, the project will bring about significant benefits that meet the demand in the wastewater treatment for over 2 million of people in Nhieu Loc – Thi Nghe canal basin and District 2, with estimated 20% wastewater volume in Ho Chi Minh city, reducing the surface water pollution in Saigon river and canals in District 2, preventing the discharge of waste into river and increasing the dilution of the river, improving the living quality for people, and promoting the development of commercial and tourist activities on and along the Saigon river. In addition, through the connection with Phase 2 Interceptor, District 2 would potentially save cost of individual wastewater treatment for the inhabitants in District 2. Because the project located at the area far away from residentials area, therefore the negative impacts from construction activities to the residents are limited. While there will be some short term localized negative impacts to the surrounding communities, to the people who are participating the traffic along Vo Chi Cong street during construction, overall the social outcomes of this project are expected to be positive by improving the water quality in the receiving bodies, thereby preserving public health and reducing diseases. Moreover, in construction and operational phases, the Project will deploy maximum of clean source of materials such as selecting low carbon concrete, recycle wastewater from truck wheel washing area for suitable puposes after primary treatment; and using clean energy as biogas or photovoltalic energy to reduce carbon footprint and susitainable development. Besides that, the Contractor is priority for new machines / equipment operating on the site, . Previously, surface water has been used during sand pumping and recycled in sedimentation ponds before discharge to the rivers In term of positive social impacts, the Project will also organize many campaigns of education or donations to surrounding local areas including schools and present workers participating to the Project. As indicated above, Environmental impacts of the Contractor’s proposed technology will be less than the expected ones in the EIA report. 5.1.2 Negative impacts Identified potential negative impacts 189 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 190 / 333 (1). Type and Scale of Project Impacts The potential negative impacts on the physical, natural, and social environment caused by the project will be identified in the table below: Table 31: The potential negative impacts Physical Natural Social Other environment Environment Cultural and Solid waste, sludge The activities of the Community. worker disturbance, safety Aquatic life, fish Land acquisition Land, soil, water noise&vibration project quality Livelihood Flooding Physical Animal Traffic Plant Air A.

Removing the existing green areas may have significant impact on natural habitats and ecosystem surrounding the project area. Construction process could also cause the loss of terrestrial ecosystems, aquatic systems and changing of the river flow rate. Especially the relocation works of Phu My creek may have impact to aquatic biodiversity in the creek and any variation due to seasonal flow variations such as the impacts on local fish populations. Many fish species depend on structured habitats for refuge from the current. The loss of natural habitat can render new dredged habitats unsuitable for shallow-water fish. Furthermore, deeper habitats may make a river more vulnerable to exploitation by invasive non-native species. Therefore, before the working activities, Contractor conducted aquatic biodiversity survey and hydraulic study survey in the Project area: • The characteristics of the Southern rivers are the semi-diurnal tide regime, the water level rises and falls twice a day, the time difference between consecutive days is by 1 hour. This schedule is repeated every 15 days. Fish categories found in the area are Cá lóc (Channa Striata), cá rô (Anabas testudineus),.... (see Table 28). The characteristics of these fishes are that they like to live in murky, grassy areas, near estuaries, live well and adapt to many different environmental conditions. 195 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 196 / 333 • Spawning season is around April, and the dreged work of Phu My creek will not be conducted during this period. During the creek relocation, the dregging work for new canal (Ngon Ngay) shall be finished before closing and dredge work of the existing Phu My canal. This dredge work on Phu My creek will be performed gradually and this will help local aquatic species to familiarize with new environment (from Phu My to new Ngon Ngay canal). Hydraulic Study for creek relocation work: • Phu My creek (47.5 m3/s; 4.5 m depth and 50 m wide); • Ngon Ngay (initially no flow, primarily mud of 1 m depth and 12 m wide, now, after dredging works, it is the same flow as Phu My), • Ky Ha creek (65 m3/s; 5.5 m depth and 40 m wide). As part of the preliminary works, the existing Phu My creek running across the site from North to South will be relocated to take full possession of the Site. This relocation was also required in order to fit the WWTP in the original Feasibility Study. Thus, at the North end of the site, the Phu My creek is rerouted into the existing Ngon Ngay river via a newly constructed section of Phu My canal . This new canal is excavated by excavator on barge. Existing Ngon Ngay canal is dredged to expand to bed = 20m, depth is -3.5 m and satisfy the flow capacity of Phu My creek after its relocation. 5.2.1.6 Society The pre-construction activities may cause difficulties and obstacles along routes, traffic congestions by truck movement in/out of site, and increased risk of accidents. Construction activities can also increase community exposure to risks. In addition to the impacts already identified above, other effects could be considered in relation of workers coming from different areas of Vietnam. As project is located in urban area (District 2 of HCMC) and easily accessible, worker camp is not anticipated to be established for the local employees. During the pre-construction stage, there is no worker's camp install on-site. The migrant workers hire local houses within an urban area for accommodation. Nevertheless, there will be an increase in the number of residents and traffic density in the places surrounding the site when the project is launched, and conflicts may also arise between the locals and new comers due to differences of their culture and customs. In addition, influx of migrant workers could also bring security problem and cultural conflicts. Workers often live far from home, so their entertainment hobbies may include mainly drinking and gambling. It can lead to communicable diseases, thieves, therefore it may cause bad effect on social condition. Among issues that can be identified it the potential risk of transmission of COVID – 19 desease, use of drug or unsafe sex which can cause Human immunodeficiency virus (HIV) and other STIs. 196 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 197 / 333 Additionally, as indicated further the Contractor will have a plan to control these effects and mitigate them appropriately. 5.2.1.7 Flooding Because the WWTP site area is adjacent to the river, the flood during high tides or heavy rains is a potential risk for the Project, it will cause of suspension of the works during flooding. The site clearance, topsoil removal activities may sweep sediment, soil and waste into the existing canal system, especially construction work is carried out when the tide is high. Dredging Ngon Ngay canal bed can cause erosion the banks during working process. However, during pre-construction stage, the Contractor carries out the main platform works and riverside dyke execution by using barges to lift up machines/equipment during their works, therefore the impacts will be limited to the works by flooding. 5.2.1.8 Traffic Every day, many trucks delivery construction materials, waste from site clearance in/out of the site will increase the traffic density in the local areas. However, Contractor has the plan to use barges for delivery large quantity of construction materials and waste from site clearance. • The quantiy of vegetation waste on site is about 800 tons. The load capacity of each dedicated truck is about 9 tons. The transportation schedule is 3-4 trips of waste out of construction site per day, within 3 months. • Total quality of sand for backfilling is about 491,000m3. Expectation plan is 7-10 trips barges per day. Capacity of each barge is from 7,000-10,000 m3. • Estimate the steel volume is about 200 tons. The Contractor will transport steel by barge in 4 months, 1 trip/month, 50 tons/barge/day. • Volume of rock is about 13,000 m3. The transportation will be carried out by barge in 4 months. 300-400 m3/barge. • Concrete will be transported by mixer truck. 8m3/truck, 12 trips/day, 1 day/month, this work will be conducted in 4 months. The frequency of transportation material and waste of project by truck/roadway is not dense and interrupted. Therefore, this is not impacted significantly to the local traffic. 5.2.1.9 Risk Assesment Risks are assessed for each work items during the pre-construction stage as following: A. Risk assessment for Site clearance and backfill of platform: a. Site orgarnization: 197 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 198 / 333  Preliminary searches: - Searching for underground piping can damages or leakage of existing pipes cause of contact with water pipes of Package XL04; - Contact with an expected mine or bomb may cause of blasting or fatal accident during site clearance; - Contact with overhead power lines and cables may exposure to the effects of electric current, electrocution.  Boundaries, site entries - If site boundaries are not installed, it may cause of danger to “third parties” as local, unauthorized people when they come in site. The trucks, equipment may hit or damage to the people and properties. - Theft of materials, danger to personnel working on the site such as workerss, inspectors, engineers, sercurity guards if site entrance is not closed.  Traffic on site - During transportation process, it may exist some risks such as collision between vehicles, falling objects/material on existing roads, overturned vehicles, people may fall out when they are transported in unappropriate vehicle for that purpose. - Personnel may trip and fall out cause of unstable ground, failure to respect the use of protective equipment or obstacles in gangways.  Ambient environment of working area - Storm water may sweep waste, tubidity to the water receptors next to project because lack of drainage system. It causes of impact to surfacewater quality. - Leakage of domestic wastewater, discharged solid waste, hazardous waste/chemical into the environment may cause of infectious diseases and harm to the health of workers, contaminate ecosystem. - Exposing with temperature and climatic work conditions may lead to high risk for health of workers. - High level of noise and vibration generated by equipment cause some occupation diseases such as ears problems, deafness, motion sickness. b. Cutting trees Cutting trees activity may damage to the local ecosystem. Many trees will be cut down. It may include the specific trees need to be protected. Beside, it possibily exist some other risks such as dead by drowning, workers fall from a barge, cutting/hurting of manpower. 198 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 199 / 333 c. Backfilling  Backfilling work may bring about personnel hits, permanent injury, fatal accident because bad knowledge of the ground's density, lack of personnel next to the machines and functionning engines, do not use/lack of PPE.  Sand pumping: - Preparation and sand transportation may cause dead by drowning, barge turned over, barge may touch to the object beneath the river/canal. - Pumping sand may cause the driver attempts to get out of the cab while the machinery/truck is overturning. - Wastewater after sand pumping may discharge directly into river/canal if the sediment pond is not installed. d. Prefabricated Vertical Drians (PVD)  Piles driving built on site or prefabricated exist some risks such as: personel can be hit, wound, injuried by pile falling over during its shifting; inconvenience between worker and machine interaction. e. Transportation by water ways - Slip risk occurs when the foot skids, usually on a wet or slippery surface and the person falls backward or forward; an obstacle stops the foot and the person falls forward. - Same-level falls can be the result of an unrecoverable slip or trip. Another type of same-level fall is a step and fall, when the front foot lands on a surface that is lower than expected. In this type of fall, the person usually falls forward. - Elevated falls include falls from stairs, equipment, ladders, and falls through holes in decks, and uncovered or unguarded hatches - Many factors can contribute to slips, trips, and falls on a barge. Some of these are gear and equipment on the deck, changing walking speed or direction, slippery surfaces (oil and water), fatigue, carrying heavy objects, visibility, and unsuitable footwear. - Fall risk cause the deck of a barge or work platform is not equipped with an railing system, hazard working surface conditions, mechanical failures, lack of gangways, PPEs, overextending the body when performing taks. - Material, oil may be falled, leaked into the water body. f. Working near water border  Excavation near rivers may lead to risks like fall of machine or people, vehicle overturned because people/equipment stay too close to the river border, lack of vision, overload, saftey distance between 199 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 200 / 333 vehicle not respected, too many machines staying in narrow platform, unsatble platform, storm, large waves, etc. B. Risk assessment for River dyke construction: a. Concrete sheetpile driving may exists some risk as injury, fatal accident because fall of persons located on a higher level, breaking and collapsing of sheet piles, impact by plant equipment; ear problem, deafness, motion sickness because exposure to vibrations, high level of noise. b. Concrete sheetpile lifting up and driving can cause some incident such as hit, wound, fatal of worker when plant falling over during its lifting, proximity of worker and equipment. c. Install head beam sheetpile may lead to some risks such as person fall from high location, object, debris falls during handling, stuck between objects, debris. These cause of personnel hit, injuries, fatal accident. d. Scour/Rock fill installation at the bottom of the sheetpile  Some risks like choke due to landslide, personnel hit, wound, material damage, fatal accident are occurred because lifting equipment breaking, unsuitable lifting methods, manual shifting of heavy and cumbersome equipment of tools. e. Excavation and installation of the anchor plate:  Fall of a person located on a higher level when moving along the talus slope, collapsing of the excavated earth slope, plant falling over cause obstructed slope, missing protection on edges of slope, do not use PPEs, bad knowledge or excavation methods, falling due to unbalanced or waterlogged ground.  Installation of the anchor plate: many risks are occurred due to lack of construction protection equipment (parapet,..), unsteady installation of the equipment, unappropriate hopper barges, unsuitable lifting methods, lac of formwork resistance. These causes will lead to consiquences such as personnel hit, injury, fatal incident, crush, choking, wounds and material damage. f. Phu My creek diversion:  During construction process, some mistake like stand too close to the river, lack of vision, overload, failure to comply safety beween motorcycles, gathering too many machines on the same narrow ground, etc. can cause of collision for people, damage materials and equipment, drowning, fatal accident.  Oil leakage is likely to flow into the river, causing water pollution.  Risk of fall into river due to the barge floor is not equipped with a hadrail system, construction surface conditions are dangerous, mechanical damage, lack of access way, PPE, the body has to stretch too much when working.  Dredging Ngon Ngay canal bed can cause erosion the banks during working process. 200 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 201 / 333  The creek diversion can be happened erosion and sedimentation along the Ngon Ngay canal and at its confluence with Ky Ha, as well as an increased flow and slightly enhanced traffic (mainly by local personal boats) on Ky Ha. For more detail, Contractor has prepared risk assessment during pre-construction at separated document that is shown in the Appendix 8. 5.2.2 Environmental and Social Impacts during Construction Period 5.2.2.1 Air quality, noise and vibration a. Air quality Dust and exhaust gas emission will arise from excavation works, transportation of soil, machinery, equipment working on site and solid waste transportation during civil works. Dust and exhaust gas emission can also occur from various construction activities such as transport of materials, equipment delivery and installation, and operation of construction equipment for foundation, excavation, piling works, etc. Solid particles can also be generated from welding and cutting works. However, impacts could be mitigatedif the Contractor uses proper method to avoid contaminating the ambient air quality in the vicinity of the construction areas and transportation routes. Moreover, old equipment and vehicles that generate black exhaust smoke should not be used on site. The impact is also minimized thanks to far distance from WWTP to residential areas (approximately 400 m). The impacts of airborne particles from construction works therefore are likely to be negligible. b. Noise and vibration Noise and vibration disturbances are particularly likely to occur related to: - the transportation of construction materials and equipment from outside of the site; - operation of construction equipment including dump trucks, bulldozers, rollers, excavator, and land scraper machine; - movement of trucks will increase the traffic levels when offloading and delivering construction materials and plant equipment; - drilling machine for bored pile works, driving piles caused by operation of heavy machinery Below is the magnitude of traditional/old equipment. By today, the equipment is upgraded with robot system, such as pilling machine, therefore, the noise and vibration is reduced around 65-75 dBA. 201 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 202 / 333 Source: Environmental Protection Department of Hongkong Noise is likely to be an on-going issue throughout the construction phase. These impacts can affect workers as well as local people. The construction period include many piling activities, the impacts to workers are assessed as significant. Workers and equipment operators will be equipped with all necessary personal protective equipments. In relation with local communities, the distance from construction site to the nearest surrounding residential area is 400 meters meaning that such impact is likely to be negligible in comparison with that from heavy vehicle movement on the roads which located between residential area and construction site. 5.2.2.2 Solid waste, water a. Solid waste During the excavation works: - 91,246m³ for mass excavation of the WWTP buildings (out which 58,376m³ will be sand and 32,870m³ will be soil of layer 1). During bored pile works: - Soil mix with mud will be released about 4,000 m3. - Soil generated during the construction of D-wall about 4500 m3 - Soil mix with mud will be released about 4,000 m3. - Exacavated material for networks : 40.000 m3 Construction waste is obtained from construction phase is about 5000 tons. Solid wastes could contaminate the surface water course, ambient air, and soil as well as water course environment if there is not satisfactory temporary storage and final disposal plan. b. Domestic solid wastes Domestic solid wastes will be generated from the offices and worksites. The quantity of domestic wastes in the maximum Construction period is about 400 workforces at highest paek working on the site (an average of 0.5 kg domestic waste /person/day or 200kg domestic waste/400 people/day). This type of waste tends to contain about 60 to 70% of organic matter. If not collected and managed appropriately, this could lead to creating favorable conditions for pathogenic vector development. 202 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 203 / 333 c. Hazardous waste Hazardous waste generated on site from machine machine maintenance and other activities are elements such as fluorescent lamps, discharged oil, chemicals used in construction (paint, sika, etc.), gloves infected by oil, chemical, oil cans, paint cans, etc... with the estimated quantity is about 400 kg/year. If there is no appropriate management and storage methods for the above-mentioned wastes, such pollutants are highly likely to have adverse impacts on surrounding environments, particularly surface water sources, ground water, soil, etc. d. Water quality o Domestic wastewater The number of workers from construction phase is about 400 people. Domestic wastewater from these workers equal to 80% daily water supply is about 30 m3 per day. o Washing vehicles/machinery/construction site The number of vehicles per day is about 45 with washing demand of 40 liters/time. The volume of wash water is 02 m3 per day. Concrete curing water, waterproof test are not released regularly with the total volume about 500 m3 Uncontrolled wastewater (e.g. sewage, wash water, construction wastewater) discharges have the potential to contaminate soil, water, and spread disease. Impacts may include sedimentation and an increase in nutrients affecting water quality and aquatic life in the receiving bodies, and this contamination due to an accidental release of hazardous substances, other waste materials into the river ecosystem. Obviously, washing water from equipment can be polluted with hydrocarbons (e.g. oil and fuel) or bentonite which have a detrimental effect on aquatic life, water quality and soil quality. Additionally, there are also human health impacts regarding hydrocarbon exposure which varies in severity depending on type and length of exposure. The significance of the impacts depends on the scale of the release, duration of piling works, civil works, local worksite topography, soil type, rainfall levels, and the sensitivity of the receiving water environment. Because the construction site is located adjacent to the receiving water source, any release could be significant. It is vital to plan and manage works carefully, more importantly consideration should be given to works completed during the wet season. While the potential impacts of uncontrolled discharges of wastewater can adversely affect the receiving water environment, they can be easily mitigated through planning and implementation of mitigation measures. o Mud Effluents/Bentonite Effluents These effluents can cause negative environmental impacts and lead to severe soil and water contamination if they are not collected and treated properly in case of overflow due to riks of equipment operation for recyle bentonite slurry in the container tanks. o Storm Water run-off/ Underground water 203 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 204 / 333 The storm water runoff may also impact on the construction works and the receiving water environment. In fact, rainwater does not contain ingredients of high pollution, but mainly contains inorganic suspended solids. Rainwater runoff, however, may cause flooding in the construction area that directly will affect construction activities with presence of workers, and may lead to an increase in water pollution and development of parasitic diseases. Piling works, earthworks, and structure construction activities will generate waste materials such as mud, pieces of broken material, sand, soil, gravel and waste oil. In the rain, they will be washed away into the Saigon River, Dong Nai River and Ngon Ngay Canal, and affect the water quality of these water sources. Therefore, it is necessary to separate rainwater and solid waste in order to avoid adverse impact on water sources. Moreover, the deep excavation will require dewatering underground water. Overall, the surfacewater quality could be significantly impacted if the water and wastewater from excavation works is not collected, managed and treated properly.Due to the location of the Project near big rivers, the impact is high but can be managed and mitigated via good construction practices. 5.2.2.3 Natural resources Fuel consumption for machinery, generators or any kind of resources consumption during construction (electricy, water, metals, gravels, ...) will have more or less impact in reduction of natural resources. Therefore, the choice of material, equipment and method statement will be crucial to minimize the impact to reduce carboon footprint of the Project. As assessed during the ESIA period, the major impact is removing the existing green areas, leading to change in temperature and humidity of sub-region. Similarly, construction process could cause the loss of terrestrial ecosystems and aquatic systems. The loss of wetland vegetation increases the river flow rate and reduces water regulation in the dry season. In addition, soil washed into the river and canal will increase turbidity, affecting aquatic species. Noise and vibration from pile driving activities may be impacted to the aquatic life and fish such as the presence of noise and vibration could keep fish away from preferred spawning sites. It could also mask natural sounds that are important to the fish, such as communication sounds from other fish, and sounds produced by prey and approaching predators. Possible changes in ecology, bodies of water, loss of ecosystems around the site can be impacted significantly if the volume of wastewater is not observed and treated timely. 5.2.2.4 Society The construction activities may cause difficulties and obstacles along routes, traffic congestions by truck movement in/out of site with the percentage increase in traffic caused by the project will be relatively high, and it will be also increased risk of accidents. With hundreds of workers (400 at peak time) coming to the site everyday, traffic accident can happen at the entrance in the intersection with public road. In addition to the impacts already 204 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 205 / 333 identified above, influx of migrant workers, transmission of deseases, sexual abuse, use of child labor, conflict in culture with local people could be considered in relation of workers coming from different areas of Vietnam. As project is located in urban area (District 2 of HCMC) and easily accessible, worker camp is not anticipated to be established for the local employees. However, during Covid restriction, there is a small worker's camp installed on-site to adapt to the requirement of the local authority in case movement is not allowed. Normally, the migrant workers hire local houses within an urban area for accommodation. Nevertheless, there will be an increase in the number of residents and traffic density in the places surrounding the site when the project is launched, and conflicts may also arise between the locals and new comers due to differences of their culture and customs. Among issues that can be identified it the potential risk of transmission of COVID – 19 desease, use of drug or unsafe sex which can cause Human immunodeficiency virus (HIV) and other STIs. Additionally, as indicated further the Contractor will have a plan to control these effects and mitigate them appropriately. The land was already hand-over to the contractor. In addition, no aquaculture activity within 1km diameter from the construction site, thus the impact of construction activities to aquaculture activities and livelihood of local residents are neligible. 5.2.2.5 Traffic Every day, many trucks delivery construction materials, solid waste from construction activities in/out of the site will increase the traffic density in the local areas. • The quantiy of concrete materials is about 62,500 m3. The load capacity of each dedicated truck is about 10 m3. The transportation schedule is about 9 trips of concrete mixer trucks go in construction site per day with the work duration in 2 years. • With 68,000lm of PHC piles, the expectation plan is 1-2 trips container per week. Capacity of each container is about 18-20 pipes working in 2 years. • Estimate the steel volume is about 9000 tons. The Contractor will transport steel by container in 2 years, 4 days one trip, 40 tons/trip/day. • Estimate the cement volume is about 12,000 tons. The Contractor will transport cement by container in 2 years, 2 days one trip, 30 tons/trip/day. • The excavated materials will be transported by dumptrucks 10 m3 within the site with the distance is about 500m/one trip then it is needed to transport 13 trucks/day during 2 years. The frequency of transportation material and waste of project by truck/roadway for 2 years working period is not dense and interrupted. Therefore, this is not impacted significantly to the local traffic. The level of impact is assessed as moderate. 205 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 206 / 333 5.2.2.6 Flooding, erosision, land subsidence Because the WWTP site area is adjacent to the river, the flood during high tides or heavy rains is a potential risk for the Project, it will cause of suspension of the works during flooding. Land subsidence can happen due to weak soil structure However, during construction stage, the Contractor carries out the main drainage systems through trenches, therefore the impacts will be limited to the works by flooding. 5.2.2.7 Risk Assesment Risks are assessed for each work items during the construction stage as following: A. Risk assessment for foundation works: Health and safety: - Heavy equipment can lead to injuries during movements - Fall of person or machine, collapse due to unstable ground or not appropriate access (unsafe pathway) - Fall of material (piles) during lifting operation or due to equipment failure - Risks of cut, burn, fire due to cutting, bending or welding activity (eye injury, lacerations due to spring actions) may lead minor injuries - Material delivery may lead to some risks such as road accident because truck collides with passengers/workers or other vehicle during driving - Collapse of pre-assembled reinforcement cages during lifting (poor condition of slings/assessories was used for lifting, failing of lifting point, fall of the load or collapse of steel cages during operation - Risk of trap/crashing injury during loading/unloading materials. - Exposing with temperature and climatic work conditions may lead to high risk for health of workers. - Excess noise/vibration during a long period can lead to the high risk for health of workers. - Poor housekeeping , especially in storage area can lead to accidents or fire/explosion Risk of environmental pollution: - Leakage of domestic wastewater discharged solid waste, hazardous waste/chemical/oil into the environment may cause of infectious diseases and harm to the health of workers, contaminate ecosystem. - Consumption of fuel, water and natural resources can lead to the increase of the Carboon footprint of the Project. 206 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

For more detail, Contractor has prepared risk assessment during construction at separated document that is shown in the Appendix 8. D. Risk assessment for other works The significance and number of risks from construction of road, networks, lanscapping, architecture activities as well as installation of process equipment and instrumentation will be lower than main civil works. The main risks are identified as follows: Health and safety: - Fall of equipment during lifting operation or due to equipment failure - Fall of person into manholes of work from height - Risks of cut, burn, fire due to cutting, bending or welding activity (eye injury, lacerations due to spring actions) may lead minor injuries - Material/Equipment delivery may lead to some risks such as road accident - Collapse of equipment during installation - Risk of trap/crashing injury during loading/unloading equipments - Electrocution or electrical risk during installation - Exposing with temperature and climatic work conditions may lead to high risk for health of workers. - Excess noise/vibration during a long period can lead to the moderate risk for health of workers. - Poor house keeping at material storage area, access way may cause accidents of slippy, falling - Risk of environmental pollution:When using radioactive source for testing may cause radiation emission - Leakage of domestic wastewater, discharged solid waste, hazardous waste/chemical/oil into the environment may cause of infectious diseases and harm to the health of workers, contaminate ecosystem. - Consumption of fuel, water and natural resources can lead to the increase the Carboon footprint of the Project. 209 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 210 / 333 5.2.3 Environmental and Social Impacts during Operation Period 5.2.3.1 Air quality and Noise & Vibration a. Air quality Air quality within the plant and surrounding areas will be affected to the environment quite significantly by odors of combustion and toxic gases (H2S, NH3, amino acid and CH4): - from influent pumping station - from screening building and grit removal tanks - from sludge treatment facilities especially at the Sludge thickening, Sludge dewatering, Biological Sludge tanks - from Biogas/CHP - Besides that, the chemical vapor during the transportation, usage and storage can be released into the atmosphere which can affect to the health of transporters and workers. It could cause discomfort to labors working within the plant and traffic users at the adjacent road if no preventive measure is taken. Also for Thanh My Loi Residence with the radius of 300m : Odors and aerosols released in anaerobic digestion tanks, pumping stations, sewage screen, and sludge collecting tank in WWTP often contain H2S, NH3, amino acids, and mercaptans. Unfortunately, in the dry season from March to May, North - North West wind will spread the odor from the WWTP to Thanh My Loi B residential area, if no mitigation measures are taken. Besides, the aerosols containing bacteria (E. coli, intestinal bacteria) and fungi in also can spread by wind with the radius of 50m which will affect directly to workers. Emission of substances in powder from reagent storage or failure during unloading process can lead to air contamination, and respiratory problems to workers. The GHG saving efficiency is about 90% to be converted in energy, excess will be burn at gas flare. b. Noise & vibration Noise generated in operation phase is mainly from pumping station ; and air blower, and generator, compressor, fan for odor control. Equipment operation noise must be within 85dBA (QCVN 24:2016/BYT on National Technical Regulation on Noise - Permissible Exposure Levels of Noise in the Workplace). However, in case of trouble happened to these equipments so this is the source of noise & vibration pollution for surrounding areas, especially for workers/technicians who operate directly in the plant without appropriate minimization measures. In addition, noise is generated from vehicles go into and go out the plant to transport chemical and waste, sludges. However, this noise course source is not regular, therefore the impacts are not significant. 210 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 211 / 333 5.2.3.2 Solid waste, sludge a. Domestic waste In operation phase, 113 people estimated to work in the plant, hence the estimated solid waste generated is about 136 kg/day. Solid waste shall be collected at designated areas and sorted as needed as well as transported to landfill regularly in order to limit the risk of arising odour and pathogenic organisms affecting workers’ health. The amount of domestic waste is not much, therfore the impacts of this source are low. b. Solid waste and sludge from the operation process of WWTP - Solid waste (sand, waste from screening and grit removal uni) produced from the plant operation: 18 ton/day. - Sludge after thickened, digested and dewartering will be stored temporary in silos with the sludge volume discharged about 94 tons/day However, if the solid waste and sludge is stored long time and in the open spaces on the WWTP that its smell will impact seriously within the plant and surrounding areas. c. Hazardous waste Amount of greasy cloths is used in the maintenance and repairing of machinery in the plant operation. Chemical, greasy cloths, paintings, solvent, containers of hazardous wastes must be packaged and stored in the standared storage area. If they are placed near the water source, they will pollute of surface water source and groundwater in the area. Cartridges, batteries from office areas are also another source of pollution if not managed properly. The expected produced hazardous waste is ablout 49.2 kg of packaging, chemical containers/day With a huge amount of solar panels are installed in 15,000m2 area then some of them will be failed and need to replaced during using or they are thrown away at the end of their life. They will have a serious impact on the environment if not properly managed and handled. 5.2.3.3 Wastewater a. Domestic wastewater The amount of domestic wastewater is estimated about 10,7 m3/day for people working in the Plant. b. Technological wastewater Wastewater is generated from the sludge dewatering system, laboratory, other facilities… is called technological wastewater in common. It contains many different pollutants (floating substances, greases, oil, solvents, sludges, phytosanitary products or other hazardous components) unless it is treated thoroughly before being discharged 211 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 212 / 333 into the receiving source, it shall cause negative impacts on the surface water quality and soil contamination in the area. If this wastewater is stagnant in the environment, it shall cause unpleasant odour due to the digestion of organic matter. Suspended solid discharged into the environment shall float on the water surface and create a thick layer which shall turn into gray after long time, affecting to aesthetics of the area; but the most important is that this floating layer shall prevent the oxygen exchange and light transmission and causing the lack of oxy for water source. Otherwise, part of sediment which depositing down the bottom shall be decomposed in anaerobic conditions creating the bad odor for surrounding area. Estimated volume of the operation of the plant will be: 38 m3/day Overflow or spillage of technological efflutents or raw wasteeater due to failure in operation with create tremendous negative consequences to the environments. c. Storm water runoff Storm water runoff in the plant will carry dust and other waste materials, if there is no drainage sytem then it will be discharged directly to the river without waste screening, leading to negative impact to the river natural environment. d. Treated wastewater The treated wastewater of the WWTP will be discharged near the river junction of Sai Gon - Dong Nai - Nha Be, where there are some wards of District 9, District 7, District 4, Nhon Trach, Nha Be located along the river. However, the calculated data of maximum concentration in receiving water of the project shown that the water quality of the Sai Gon, Dong Nai, Nha Be rivers meet Column B2 of QCVN 08:2008/BTNMT. In addition, wastewater after treatment to meet column A of QCVN 14:2008/BTNMT should hardly affect the water quality of these rivers. Therefore, the WWTP hardly impact on the people living in the downstream of the discharging point. 5.2.3.4 Natural resources Fuel consumption for machinery, generators or any kind of resources consumption during operation (electricy, water, chemicals ...) will have more or less impact in reduction of natural resources. Therefore, the choice of operating methos and energy source will be crucial to minimize the impact to reduce carboon footprint of the Project. Possible changes in ecology, bodies of water, loss of ecosystems around the site can be observed if there are leakage of wastewater/fuel. 5.2.3.5 Impact to water quality of the receiving water body Flow and water levels of the Sai Gon and Dong Nai rivers are significantly changed in the rainy and dry seasons, especially in the flooding months. The Sai Gon River water quality only meet QCVN 08-MT:2015/BTNMT, column B1. Therefore, the construction of the wastewater treatment plant is needed to minimize the negative impact on the Sai Gon River water quality, as well as on the Nha Be river water quality. The calculated results during 212 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 213 / 333 preparation of Environmental Impact Assessment report in 2014 show that the construction of the wastewater treatment plant will have important implications in limiting the Sai Gon River water pollution. In addition, the wastewater treatment plant not only collects and treats the wastewaters from NL-TN basin, but also the wastewater generated from District 2. Therefore, the projects will benefit not only for people living in Ho Chi Minh city, but also for the people living in the downstream of the Sai Gon-Dong Nai river basin. 5.2.3.6 Society The social assessment (SA) exercise for the project was undertaken separately during the project preparation period. In addition to the identified social impact related to land acquisition, the social impact was also examined in relation to the environmental impact assessment, and in line with the area of influence defined in the EIA. The social impact assessment confirmed that although effort made, some anticipated negative impact - as a result of permanent land acquisition, primarily for the construction of the WWTP within the proposed area of around 38 ha could not be avoided. However, the magnitude of impact is minimal given consideration of the other technical alternatives during the Feasibility Study stage. In addition, The SA and updated Feasibility Studies confirm that the overall social impact of the project is positive - because the project will improve the environmental sanitation for the two target catchment areas - Nhieu Loc – Thi Nghe area (Phase 1) and District 2 area (Phase 2). Possible odors and infectious viruses generated from plant operation due to malfunctioncan lead to bad impacts on life quality (digestive and respiratory diseases) of local people surrounding, particularly the elderly, women, and children. Polluted environment may be a basic reason, which results in reduced real estate price and decreased revenues of food & drink and entertainment services due to the declining number of tourists in this area. Covid pandemic can also affect the operation rate of the plant if internal control is not properly implemented. 5.2.3.7 Traffic The number of in/out vehicles of the plant is about 12-14 trips/day, because when the activity of transporting chemicals and sludge of the WWTP goes into operation, this will increase the density of vehicles in the area, affecting the quality of the road crossing the Phu My bridge. This also increases the risk of traffic jam, rapid deterioration of road quality, and increases risk of traffic accidents. 5.2.3.8 Flooding Because the WWTP site area is adjacent to the river, the flood during high tides or heavy rains is a potential risk for the Project. However, during operational stage, the dyke flood protection will be effective and the Contractor also carries out the main drainage systems with 02 outfalls, therefore the impacts will be limited. 213 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 214 / 333 5.2.3.9 Risk assessment Health and Safety - Error due to insufficient knowledge of technological procedures during operation and maitanence can lead to accidents - Electrical shock during operation, inspection, maintenance or damage of electrical cable - Fall of person during operation from ladder or working at height, falling down in the chamber; slipping due to lack of CPE or wet floor; entrapment in operation units - Contact with waste water/chemical/biological substances can spread infectious diseseas to workers if no proper PPEs are used - Burn, fire, cut of persons during operation and maintenance In the WWTP, the causes of fire/explosion could be:  Fire and inflammable materials in fuel storage, storehouses; Pumps, air blowers, clogged pipes or continuous operation for a long time  Carelessness of staff and technicians such as smoking and cigarette ash;  Open spaces in the storehouses is not designed properly; Electrical overloading. - Occupational deafness due to prolonged exposure to noise of equipment operating, Prolonged exposure to the smell of sludge, chemical, UV lamp can lead to health problems. The probability of these risks depends on the awareness of workers on labor safety. The impacts could be injury, occupational diseases and even death. These impacts only affect in the inner area of WWTP; however, the plant will also need a number of preventive measures of these problems. Risk of Environment pollution - Noise and virbration during operation and transportation and transits of lorries and equipment. - Solid waste and sludges generated during operation units and maintenance. - Emission of combustion gases/toxic gases/substance in powder Devices and equipment of the treatment plant can be located in locations with accumulation of toxic gases/substances, which can cause fire and explosion, air contaimation such as inlet pump station, anaerobic digestion tank, etc., - Odors from waste, sludge - Bad quality of treated water discharged to river due to operational issues In the operation of WWTP incidents such as equipment damage, clogged pipes, improper operation, problems with UV systems may happen. If the problem occurs, the efficiency of WWTP will be decreased. In this case, it will 214 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 215 / 333 increase levels of organic matter in the surface water; increasing algal development or eutrophication status of water resources; increase harmful bacteria to aquatic life living in the river, causing spread of cholera to the people living along the river. - Spillage of sludge In the sludge thickener, sludge could spill out by the gravity rule, resulting in negative impacts on the environment. - Spillage of wastewater due to operational issues - Chemical leak Common reasons causing chemical/dangerous substances leakages in WWTP are: the barrel contains leaks due to defects in the cap or not-tight covering; carelessness in the transport, chemical spills when moving containers. The chemical leakage will affect directly to the workers by inhalation or dermatological adsorption. Chemical/dangerous goods pose a great and immediate risk to not only workers and members of the public at or near the site but also to the general environment. - Consumption of fuel, water and natural resources will increase the Carboon footprint of the Project. Lighting, traffic, flood and social aspects also affect the working environment. 215 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 216 / 333 CHAPTER 6: CONTRACTOR’S ENVIRONMENTAL AND SOCIAL MANAGEMENT PLAN 6.1 Mitigation Measures of Negative Impacts 6.1.1 Mitigation measures during pre-construction period 6.1.1.1 Land acquisition Land acquisition has been done by UICI under the Minutes of handling over construction site areas (Site area for the Nhieu Loc – Thi Nghe Wastewater Treatment Plant) dated 23 December 2019. However, during the execution of the XL-02 package, there was a situation of disturbance, obstructing the construction from February 2020 of the group led by Mr. Nguyen Van Chinh. Mr. Chinh representing the cases still claiming support for site compensation are Mr/Ms. Huynh Van Cam, Duong My Linh, Tran Thi Huong. However, according to information from District 2's compensation and site clearance committee, a written reply is that there is no legal basis for compensation and support settlement. Many troubles and obstacles are still continue at the construction site till now. On 30 March 2022, UICI has proposed to the People's Committee of Thu Duc city to continue directing the relevant agencies to completely solve the case of disturbances and obstructions to carry out the construction of the NL-TN WWTP and have plans and measures to support it (for example, appointing the Ward police force, the Thu Duc City police to handle according to regulations) so that the work can continue to be implemented. 6.1.1.2 Management of Unexploded Ordnance (UXO) UXO clearance of the site area has been conducted (see Appendix 9). However, some UXO may remain. In case that the Contractor finds a UXO in the course of construction, the handling methods below will be applied. This will be disseminated to all staff and workers during the induction process: • If a suspect UXO item is found - DO NOT TOUCH, disturb or tamper with the item in any way. This includes making any attempt to move the item to a safe location; • Carefully note the appearance of the item and the location. Take a photograph if it is possible to do so without further approaching or disturbing the item; • Make the fence surrounding the object and arranging guard to prevent the contact of workers/local resident. Colored tape or paint make easily recognized marker material.

Grievance redness mechanism of project It was recognized that a credible and effective grievance mechanisms is important to ensure all social adverse impacts, particularly those related to land acquisition, are timely and effectively addressed. The grievance redress procedure shall be implemented as follows: • First Stage: Commune/Ward People’s Committee (C/WPC): An aggrieved affected household may bring his/her complaint to the One Door Department of the Commune/Ward People’s Committee, in writing or verbally. The member of CPC/WPC at the One Door Department will be responsible to notify the CPC/WPC leaders about the complaint for solving. The Chairman of the CPC/WPC will meet personally with the aggrieved affected household and will have 30 days following the receiving date of the complaint to resolve it. The CPC/WPC secretariat is responsible for documenting and keeping file of all complaints handled by the CPC/WPC. • Second Stage: District People’s Committee (DPC): If after 30 days the aggrieved affected household does not hear from the CPC, or if the affected household is not satisfied with the decision taken on his/her complaint, the affected household may bring the case, either in writing or verbally, to any member of the DPC or the district Resettlement Board. The DPC in turn will have 30 days following the receiving date of the complaint to resolve the case. The DPC is responsible for documenting and keeping file of all complaints that it handles and will inform the district Resettlement Board of any decision made. Affected households can also bring their case to Court if they want. 233 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 234 / 333 • Third Stage: City People’s Committee (City PC): If after 30 days the aggrieved affected household does not hear from the DPC, or if the affected household is not satisfied with the decision taken on his/her complaint, the affected household may bring the case, either in writing or verbally, to any member of the CityPC. The CityPC has 45 days within which to resolve the complaint to the satisfaction of all concerned. The CityPC is responsible for documenting and keeping files of all complaints handled by the CityPC. Affected households can also bring their case to court if they want. • Final Stage: the Court of Law Arbitrates: If after 45 days following the lodging of the complaint with the CityPC, the aggrieved affected household does not hear from the CityPC, or if he/she is not satisfied with the decision taken on his/her complaint, the case may be brought to a court of law for adjudication. Decision by the court will be the final decision. Decision on solving the complaints must be sent to the aggrieved affected household and concerned parties and must be posted at the office of the People’s Committee where the complaint is solved. After three days, the decision/result on solution is available at commune/ward level and after seven days at district or city level. However, as first contact point, PAP (project affected person) may contact either the Ward PC (where they have general questions about the project, or complaints related to aspects such as compensation costs, inventory, measurement), or UICI if they have general questions related to project scope/impact/general compensation policies. These dual first contact points provide affected households with choice of channels through which they may ask for clarification. Since grievances are commonly found in any projects related to land acquisition, to ensure the grievances are timely and effectively addressed, the following measures could be used: • A recording system for lodging complaints should be established and maintained by both District 2 and UICI, with regular update, to timely and satisfactory solve the grievances. • In case of verbal complaints, complaints need to be recorded into the recording system for following up and timely resolving. • Ward PC and UICI should appoint a contact person – each from their side, and include their names, contact phone numbers, mailing addresses (and email if applicable), in the Public Information Booklet (PIB) to enable affected households to conveniently contact for clarification/project information. At the same time, an escrow account for resettlement payments should be used when grievance is resolving to avoid excessive delay of the project while ensuring compensation payment after the grievance has been resolved. c.

Construction works will only be resumed after permission of the responsible local authorities concerning safeguard of the heritage is received by the Contractor. 6.1.2 Mitigation measures during construction period 6.1.2.1 Dust, gas emission control The mitigation measures of dust, gas emission control during construction period are similar to ones during pre- construction period (Section 6.1.1.3) because the sources mainly come from excavated materials and equipment/vehicles working on site. Equipments will be checked/maintained regularly and by third parties if necessary, to avoid any black exhaust emission or leakage before operation. Spraying water on the site will be performed regularly especially with dust- generating materials. 6.1.2.2 Noise and vibration pollution control The mitigation measures of noise and vibration pollution control during construction period are similar to the ones during pre-construction period (Section 6.1.1.4). Operators working with noisy equipment like driving machines with hammers will be strictly requested to wear ear defender during operation. To mitigate the noise and vibration by hammers during pile installation, Contractor plans to use robotic system instead of hammers for pressing pile gradually into the soil. The noise and vibration is considerably limited and do not affect aquatic life around. 6.1.2.3 Water pollution control a. Domestic wastewater • Mobile toilet will be provided at the site with separately for male and female: o At existing site area: 4 toilets for men, 4 toilets for women o Criteria for toilet: 01 toilet for 10 male workers, 01 toilet for 10 female workers.

Water in sedimentation ponds will be regularly checked before discharging to the river. • Oil and sludge from washing area pits are collected by A Chau Service Environment Company Ltd. • Wastewater from construction site is pumped directly into the temporary sedimentation ponds at flatform area that is constructed for the preliminary works before discharging to the river. The wastewater will be periodically monitored before discharging into the river c. Mud effluents/Bentonite effluents During excavation and drilling activities, specialized equipment for recycling bentonites will be implemented. Cleaning up action will be ensured if any leakage is detected. d. Stormwater run-off / Underground water • Fuel and materials shall not be stored near the drainage system. • Preventive measures are taken to avoid oil leakage oil on the ground surface such as: control of maintenance of equipment, dedicated areas for maintenance, oil spillage emergency kits. • 2 temporary sedimentation ponds already constructed will be able to remove the sediment before being discharged into the river. • Temporary drainage will be set up at construction site and will be maintained regularly to avoid fuel and oil seeping or spilling into the drainage system. • Underground water during deep excavation will also be directed and pumped to sedimentation ponds. 6.1.2.4 Solid waste and hazardous waste disposal a. Excavated materials Soil in platform has been confirmed to be not polluted in the baseline monitoring. During construction phase, excavated materials will be controlled as per AVJ-A000-EN-PMP-0002 Waste Mangaement Procedure, including: Excavated materials from foundation work The excavated materials will be placed directly into a dump truck standing alongside the excavation workshop. The excavated material will then be transported to a temporary storage area on-site where the excavated materials will have time to drain. Once drained, the excavated material will be tested in the stardarded laboratory, if the excavated material samples meet the national technical regulation then it will be disposed in a designated area within the site, if not, it will be loaded and transported to Da Phuoc landfill. The procedure is described in the Appendix 11 on Waste Management 243 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 244 / 333 Bentonite mixed with water will be used as excavation supporting fluid during bored piles and D-wall execution. The bentonite slurry will be mixed on-site and stored in tanks. The supporting fluids shall be in accordance with TCVN 9395: 2012. The bentonite slurry will be recycled: • After mixing, the bentonite slurry will be stored in fresh fluid tanks • After being used during the excavation process, the bentonite will be treated and recycled in special plants and stored in tank for recycled bentonite. Excavated materials from excavation works • Sand: re-used for the project platform. • Natural soil of layer 1: very soft high plasticity silts, slightly organic to organic (MH/OH) will be temporary stored in dumping designed area of the project for the future purpose. The excavation will be carried out by layers in order not to mix the materials. The sand will be kept on site and reused for the filling works: • Backfilling of the old Phy My River (after completing the closure) • Backfill around the buildings • Final leveling of the platform prior commencement of the landscaping works. This will allow to reduce the carbon impact by not having to transport the sand to laydown areas an mobilize new material to the site later on. 244 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Construction waste Construction waste is obtained from construction of Diaphragm Walls or D-Walls, concreting works, structural works,etc is about 5,000 tons (about 5% of total supplied materials) will be minimized in accordance with the following waste management hierarchy: - Reuse: left over gravels, etc - Recycle: cardboard and paper, metal, plastic, wood; - Disposal to Da Phuoc landfill: other remaining construction waste. c. Domestic waste • Domestic waste from the site will be stored in the standard garbage bins and placed at regulated areas and it will be regularly collected 2-3 times/week by District 2 Public Service Company. • Solid waste from portable toilets will be regularly collected and transported by Dong Tam transport Cooperative district 2. d. Hazardous waste The estimated amount of hazardous waste is about 400 kg/year. • The vehicles working on the site will be maintained regularly and used oil is collected by storage tray for re-use or elimination. • Oily rags, flourescent light bulbs, batteries, chemical bottles, print cartridge contained hazardous ingredients are collected, transported by A Chau Environment Company and treated by HCM city Urban Environment Company. 6.1.2.5 Accidental spill emergency response procedure Accidental spill emergency response has been prepared and included in the procedure AVJ-A000-HS-PMP-0006 Emergency measure attached in the appendix No. 12. and AVJ-A000-HS-PMP-0022 Fuel bunkering attached in the appendix No. 13. 6.1.2.6 Natural resources Environmental friendly material such as low carbon concrete as well as good condition of equipment will contribute significantly to reduce impact in consumption of natural resources (oil, diesel, …). Moreover, construction method also plays a crucial role in reducing carbon footprint, for example, concrete deep mixing (CDM) method will use directly soil as a part of the retaining structure and will not generate excavated materials to the environment. 246 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev. L SOCIAL MANAGEMENT PLAN Date 2022-07-06 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 247 / 333 As part of an Environmental improvement, the Contractor developed a concrete mix design which able to cope with the required watertightness and chemical aggressivity of the wastewater required to contain the water. The surface coating of the concrete shall be applied on areas where there is risk of accumulation of acids (i.e., microbiologically inducted corrosion). All discharged water to the river will be controlled to avoid any damage to ecological system around the site. Control of equipment embarking to the site will be planned with low frequency to avoid any disturbance to local aquatic creatures living in the river. Suppliers near the site will be prioritized for choice to reduce emission during transportation. CO2 emission for all activities from material, fuel consumption will be recorded monthly through contractors’ (Vinci Construction Grand Project (VCGP) and ACCIONA) platforms. Other design measures that respect to surroundoung environment and landscape The architectural form is in harmony with the surrounding landscapes, the architectural lines must be gentle, avoid coarse and large cube that cause indecency. For materials, besides reinforced concrete and steel frame assembly, steel plate, insulation iron sheet, precast partition wall, lightweight materials available on site such as wood, bamboo, leaves will be used ... For surfaces covered by glass and iron sheet, it is requested to study on the sun direction to minimize the diffusion of light and heat to the surrounding environment. For finishing, materials with light, soft colors will be used, avoid high contrast, glare colors. Decoration form must be simple and suitable to the overall landscape. Architectural form, cube and color of architectural structures Architectural form • The architectural form must be in harmony with the surrounding landscapes, the architectural lines must be gentle, avoid coarse and large cube that cause indecency. • The roof slope generally applied for flat roof is 2 to 4° • The general roof slope applied for tiled roof is 33 or 45° • The roof slope generally applied for sloped sheet iron roof is 25 to 30° Density of cubes will not be too dense, causing frustration for users and observers. The distance between cubes must ensure technical and aesthetic requirements.

Therefore, ear defenders must be used compulsorily. In addition, noise is also produced from the carriages in and out of the Plant to transport chemicals and treated biological sludge. However, this noise source is not frequent and exists in a short time, so the impact is not significant. To mitigate noise pollution to the surrounding areas, the plant is planned to be built in compliance with regulations on hygienic isolation distances with green belt, and at the same time used silencing devices, to comply with QCVN 26:2010 /BTNMT such as: • Using 100% new equipment from well-known manufacturers. • Air pump, sludge dewatering, sludge pumps are put on pedestal attached to a large basement structure with rubber base; • Pumping stations are located in soundproof room, to minimize noise to surrounding areas from 10 to 15 dBA; • Workers in pumping station are equipped with ear plugs to reduce noise; • Making routes of transporting sludge and schedule for sludge trucks activities to minimize noise caused by traffic. In addition, the Contractor will manage Maintenance Plans through the use of NEPTUNO WORK WATER maintenance software, developed by ACCIONA Agua as a member of the Joint Venture for Operation and Maintenance Management. Depending on its importance in the process, location, and number of equipment available, the Preventive Maintenance Program will be defined, based on the recommendations of the manufacturers and the experience of the contractor’s personnel, which will be managed through the detailed maintenance software later. As a general way, there are 3 kinds of maintenance works: o Mechanical works o Lubrication and Grease Works o Electrical Works 269 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

In case the flow exceeding the WWTP design capacity the control loop will initiate the throttling of the valve to restrict the flow to the WWTP. In such case the surplus amount of wastewater will back up to the NLTN Shaft, where it will be discharged to the Sai Gon River. There will also be a General Bypass for the plant at the inlet of the WWTP. Whenever the water level rises over the fixed weir, the water will be conveyed to the general bypass by means of the pumps through a 2,000mm underground channel to the river. In case of emergency, or when several tanks or treatment units have to be put out of operation, redirection of the flow through the remaining treatment units will be considered and ensured. The design of the tanks and other units will be in such way, that sufficient reserved spare capacity, space and volume will be provided in order to be able to cope with the additional flow. Only in case of emergency when the aforementioned procedure is not feasible, the discharge of untreated wastewater through a separate bypass channel at the WWTP is permitted. For that purpose, a gravity bypass channel will be laid from the Inlet Pumping station to the effluent structure, where the bypassed flow will be analysed and monitored. Also, the amount of bypassed water will be measured and recorded. The bypass will be closed for normal operation by a suitable motorized penstock, which will be monitored and operated from the Scada system. 272 Ref: AVJ-A000-QA-PLA-0003 CONTRACTOR’S ENVIRONMENTAL AND Rev.

Environmental Management is described in other specific document AVJ-A000-QA-PLA-0003 Environment and Social Management Plan 5.1 General 5.1.1 Aim of the H&S plan The aim of the H&S Plan is to inform all intervening parties and the Project’s supervisory staff on Contractor prevention organization and approach for the project, in compliance with regulations in force, Contract requirements and Contractor’s H&S Management System’s requirements. H&S Plan is supplemented by Project Management H&S Procedures. A copy of the Project H&S Plan is transmitted to each Head of Department. MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 21 / 47 5.1.2 Aim of the H&S procedure H&S Procedures deal with H&S aspects in the conditions specific to the project, integrating applicable regulations and specific contractual requirements. These procedures are prepared by the H&S Engineer o Manager, approved by the Project Director and disseminated to the project’s supervisory staff during specific information meetings or induction. The provisional list of H&S Procedures is given in Appendix 2 of the present document. 5.1.3 Aim of the method statements These documents are essential for accident prevention. The method statements are originated by the Technical department or by the Subcontractor’s supervisory staff in charge of the execution of the works and reviewed by the Contractor Construction Manager (and Technical Manager if document is prepared by subcontractors). In case of in- house performing works, the methods statements are drawn up by the Technical Department with the support of the Contractor Construction Manager. Their purpose is to specify requirements, resources, methods and specific controls for a specific activity. It includes a risk analysis and prevention means. Method statements are reviewed officially by the Technical Manager before approval by the Contractor Project Director, and constitute addenda to the present Project H&S Plan and to the Quality Plan. 5.1.4 Principle for risk assessment The accident Prevention approach is based on the 9 general prevention principles (according to European directive dated 12/06/1989) listed in decreasing order of priority:  Avoiding risks,  Evaluating the risks which cannot be avoided,  Fighting against risks at source,  Adapting the work to the individual, especially with regard to the design of work stations, choice of work equipment and choice of working and production methods, with a view, in particular, to alleviating monotonous work and work at a predetermined pace and/or reducing their effect on health,  Adapting to technical progress,  Replacing what is dangerous by what is not dangerous or less dangerous,  Developing a coherent overall Prevention policy which covers technology, organization of work, working conditions, social relationships and the influence of factors related to the working environment,  Giving collective protective measures priority over individual protective measures,  Giving appropriate instructions to the workers. A preliminary risk analysis is carried out at an early stage during the design phase. It involves identification and assessment of risks related to the task under review. This analysis is incorporated in the Method statements. A risk not foreseen during risk analysis may appear when executing certain tasks. If so, works are suspended as long as the risk remains, and a specific risk analysis of this situation is carried out. Then the method statement is amended accordingly. 5.1.5 Method for risk assessment A specific risk assessment procedure is presented in the Particular Management Procedure AVJ-A000-HS-PMP-0001 “Risk assessment”. Risk identification Risks are identified by activity and then the activity is broken down into tasks (access, handling, application...). For each identified task, dangerous situations are investigated. For each identified risk, the possible causes are investigated. A template of risks analysis table is shown in the Method statement template. For each identified activity, risks are assessed using the following criteria: Probability, gravity and efficiency of protection measures. MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 22 / 47 The evaluation method is based on 2 factors: - The Probability: it indicates the likelihood of the effect. - The Gravity: it indicates the severity of the consequences of an accident RISK = P x G The following tables is used to assess the above variables: Probability The Probability ratio quantifies the number of times a risk occurs (for product quality, people health and safety, or the Environment); the following ratios should be allocated: Probability ratios Assessment Criteria 1 Very low: approx. once a month 2 Low: approx. once a week 3 Average: approx. once a day 4 High: several times a day Gravity The Gravity ratio shows the possible degree of importance of the event’s consequence. Gravity Assessment Criteria ratios Quality Health and Safety Environment Minor nonconformity which can be Minor pollution incident which Treatment or Work 1 handled immediately with no major can be handled immediately Accident without leave repair required with no major repair required Work Accident with leave Important pollution incident. Important nonconformity. Repair carried 2 resulting in temporary Repair carried out by the out by the operating team disability operating team Very important pollution Very important nonconformity. Repair Permanent disability (e.g. incident. Repair requires 3 requires involvement of an Engineering deafness...) involvement of an expert office consultant Major nonconformity challenging the Major pollution incident, the contractual quality level, or even its 4 Death impact of which could extend to ability to ensure the stability of the neighbouring people structure MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 23 / 47 Intolerable risk : To be treated IN PRIORITY in design 8 ≤ RI ≤ 16 phase 4 ≤ RI < 8 Significant risk : To be treated in design phase 1 ≤ RI < 4 Low risk: No treatment necessary in design phase Prevention/Protection measures Prevention/Protection measures are the measures taken by the project to limit the risks. These measures must be defined in accordance with, on the one hand all 9 general prevention principles, and on the other hand the causes identified during the risk identification stage. The methodology to be used to choose prevention/protection measures is as follows: Is Intrinsic prevention YES END possible? ACTION NO Are Technical means YES Is this YES 1st Level enough? possible? ACTION measure NO END Are YES Is this 2nd Level Organisational means enough? YES ACTION measure possible? END NO 3rd Level Is an Awareness YES measure campaign possible? ACTION NO REVIEW THE ACTIVITY/TASK If intrinsic prevention is possible, the risk is removed from the analysis. Otherwise, risk analysis continues, prevention/protection measures are adopted and a ratio allocated according to the following criteria: MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 24 / 47 Ratios Prevention/protection Assessment Criteria measures 1st level measures: Setting up technical means (examples: Collective protective 0.25 equipment, holding tanks, formwork vibration using jacks…) 2nd level measures: Setting up organisational means (examples: task-specific 0.5 personal protective equipment, anti-pollution kit, definition of quality control points, specific training...) 3rd level measures: Raising awareness among staff concerned (examples: Health & 0.75 Safety/Environment toolbox meetings, presentation of work procedures, awareness campaigns on good practices relating to vibration...) Setting up a hierarchy of risk A risk index is calculated by multiplying the Probability, Gravity and Prevention/Protection measures ratios. Risk index = Probability x Gravity x Ratio Prevention/Protection measures The hierarchy is set up by centralising the risks with the highest Risk Index. This centralisation enables to identify the major risks of the project. The project’s management defines the general QES strategy by its policy, objectives and action programmes according to the major identified risks. The detail of each risk analysis is shown in a table similar to the one attached in Method statement template and included in each method statement. 5.2 Compulsory registers Apart from the regulatory aspect, these documents enable the Project Management to:  be informed (in writing) of observations relating to manpower health,  check that routine examinations and inspections of equipment and installations are carried out. 5.2.1 Personnel register This register includes the names of all employees allowed to enter the job site. It is updated by the QHSE Assistant and distributed as often as necessary to the security guard in charge of access control for the job site. A copy is available for consultation by the Safety Officer office. 5.2.2 Registers of routine inspections  Heavy equipment inspection register,  Lifting devices inspection register,  Fire fighting equipment inspection register,  Portable equipment inspection register. 5.2.3 First aid cases Register This register enables recording of the first aid cases taken care for onsite and detecting re-occurrence where applicable.

It is the Contractor which issues this authorization:  After making sure of the staff's training (provided by an approved instructor/organization), according to the category of authorization;  After checking their knowledge and having their medical fitness verified (by the Doctor). The document of authorization is personal, limited in time, and contains information relating to the employer and the holder of the authorization with their signatures. It must be able to be presented in the workplace. 6.3.5 Use of explosives No explosive devices are to be used on site without the prior approval of the Project Director, and the issuance of the appropriate documentation, procedures and permits. 6.4 Medical supervision Medical supervision of personnel is to ensure that each person who is an employee of the contractor or a subcontractor, or a temporary worker is medically fit for the work station to which he (she) is assigned, and to propose where applicable either an adaptation of the work station or assignment to another station. It is the responsibility of each company to promote good personal hygiene among staff and detect any employee whose health status is not compatible (temporarily or permanently) with the work in a potable water treatment plant. Any employee found unfit must be removed from the site by his/her company immediately until his/her health status is compatible again with such activity. 6.4.1 Personnel medical monitoring The Contractor’s personnel shall have initial medical examination and annual medical follow-up examination. 6.4.2 Prevention of occupational diseases An occupational disease is a disease due to work. While the consequences of occupational diseases seldom concern directly the work in progress (the effects appearing sometimes several years later), the causes are the direct result of work in poor everyday conditions. Sometimes, the same causes can also result in work accidents. MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 33 / 47 Knowledge of the nature, causes and effects of occupational diseases contributes to the assessment of potential risks in execution of the works, with a view to acting via a prevention approach. The procedure for prevention of the causes of occupational diseases is of the same nature as the one for accident prevention (§ 5.1.3/5.1.4). 6.4.3 Healthcare on site Care given in the first aid station is recorded. Processing of information is performed by the Site first aid officer as concerns medical aspects and the H&S Engineer as concerns prevention and statistical aspects. First aid Room is located in Contractor’s offices. A permanent nurse is allocated during day time site working hours and whenever there is a need to work beyond the regular working hours. Records are kept of treatments or first aid provided. These data are compiled and analyzed regularly in order to identify main sources of consultations, treatments and sick leaves. In case of accident that cannot be handled by the nurse, the employee will be transferred to the nearest hospital (see Particular Management Procedure AVJ-A000-HS-PMP-0006 “Emergency Measures”). The ambulance service is summoned for evacuation of an injured person to the hospital designated by the nurse. Another vehicle (e.g. messenger) is designated/used for occasional transport not requiring the use of an ambulance (slight injuries, outside medical examination, etc.). Exercises in evacuation of the injured will be held regularly, analyzed, and recorded by the H&S Department/Safety Officer and all concerned supervisory staff. 6.4.4 Measures against STD, STI and HIV/AIDS In order to prevent transmission of infectious diseases from local people to workers and vice versa, some measures are to be taken as follows: - Conduct orientation for construction workers regarding health and safety measures, emergency response in case of accidents, fire, etc., and prevention of HIV/AIDS and other related diseases - Ensure cleanliness of work sites, and undertake proper maintenance of sanitation facilities; implement measures to avoid proliferation of disease vectors such as flies, mosquitoes, rats, etc… - Implementation of a training program for workers through an accredited service provider regarding prevention, detection, screening, diagnosis of sexually transmitted diseases such as HIV/AIDS, human trafficking, and drug use and other vices 6.5 Protective equipment 6.5.1 Collective protective equipment The collective protection equipment mainly concerns the measures:  intended to prevent the fall of people, objects and materials,  intended to ensure ventilation of confined spaced or workplaces or that may contain contaminating substances,  intended to prevent traffic accidents,  intended to protect people living in the vecinity of the work site. MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 34 / 47 For work at height, appropriate scaffolds should be used and approved by the Contractor, which should be stable and with handrails to protect personnel. The control of the provisional works is detailed in the Particular Management Procedure AVJ-A000-HS-PMP-0011 “Temporary Works Control”. Also, all personnel exposed to a risk of falling must be protected at the workplace or circulation level by handrails with anchorage in accordance with current regulations. For a protection to be effective, it must have an adapted geometry, stability and verified resistance, be continuous in space and permanent in time. Ventilation of workplaces: It is necessary to distinguish between the ventilation of premises with non-specific contamination (pollution related only to human presence) and the ventilation of premises with specific contamination, that is, those where hazardous or annoying substances are emitted in the form of gas, aerosol vapors ... etc. In the latter case the ventilation will depend on the contaminants found. There are two principles to reduce this pollution:  general ventilation, which consists in decreasing the concentration of the contaminant below the exposure limit values through the supply of new air,  local ventilation, which consists mainly of capturing the contaminant at the source for expulsion outside the work environment. These ventilation systems give rise to a specific study of the work environment and regular monitoring. For work in confined spaces and in the vicinity of existing sewerage networks or inside them particular attention should be taken following the principles below:  only qualified people can work,  a permanent control of the gases with detector and alarm should be carried out during the interventions,  initial ventilation should be installed,  a relief or rescue team will be left available to the brigade.  breathing apparatus, safe access and egress; and lifting equipment for emergency rescue need to be provided Those works shall be performed in conformity with the Particular Management Procedure AVJ-A000-HS-PMP-0009 “Works in confined space”. 6.5.2 Personal protective equipment (PPE) In addition to compulsory PPE such as the helmet, safety shoes and/or boots and reflective jacket, gloves when reducing or eliminating risk at source was not possible or when setting up collective protection systems proves impossible or incomplete, specific PPE, adapted to the work stations and risks incurred, is provided to the personnel by their respective company. Choice of PPE: The supervisory staff, personnel and H&S team are involved in the choice of PPE. It must be conform to international standard, new, hard-wearing, comfortable, have a performance level appropriate for the intensity of the risks, and it should not make work more difficult, as it may as a result not be worn. MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 35 / 47 The preliminary risk assessment defines the nature of the PPE to be worn (ear protection, goggles or face shield, specific gloves, safety harness, filter masks, etc.). The helmets will have a specific color code for eah position (Superviros, Security team, quality team, operatos, workers). Purchase of PPE: The purchaser coordinates with the H&S Engineer or Safety Officer for advice on the choice of supplier and type of PPE which can be used on site. This latter makes sure that purchased equipment is fit for the use that will be made of it. The Safety Officer ensures that a stock of PPE is available anytime to provide equipment for new comers (Contractor’s employees only) on site and to ensure renewal of damaged or worn PPE. PPEs for Subcontractor employees’ PPEs are purchase by their company. If the Subcontractor does not comply the Contractor will purchase en provide the PPE to the workers at subcontractor cost. Distribution: All Contractors and subcontractor’s employees working on site (including temporary workers) receive free of charge, at induction or in the case of an exchange, the following mandatory personal protective equipment:  Safety shoes or boots  Safety helmet  Reflective jacket  Gloves  Coverall  Safety glasses  Ear defenders or plugs Specific PPE (specific gloves, safety harness, filter masks, welding mask, etc.) is handed over to the Contractor personnel by the Safety Officer as need be. When PPE is handed over to Contractor personnel, this is recorded on the employee individual PPE issuance log sheet. Use and maintenance of PPE: All supervisors (Contractor and Subcontractor) must ensure that PPEs issued are used. This compulsory rule is covered by the instructions given during induction. Employees are informed of the risks which the PPE is designed to protect against. They also receive instructions for use and possibly training on wearing PPE (e.g. safety harness, etc.). These general conditions of use are dealt with regularly during toolbox meetings. PPEs are personal objects and, as such, the employee must look after them. It is however the project’s duty to see to the repair and/or replacement of this PPE free of charge when it is reaching end of life, and to check specific PPEs regularly. Subcontractors MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev. B PROJECT HEALTH AND SAFETY DESIGN, BUILD AND OPERATION OF MANAGEMENT PLAN Date 2020-03-03 THE NLTN WWTP, HCMC Page 36 / 47 Unless otherwise stated in the subcontracting contract, each company manages the supply to and use of PPE by its personnel. Each employee of a subcontractor must be provided with PPE by his company and must use it, just like all employees involved in the works on site, failing which, sanctions will be taken in accordance with the project’s internal rules. The Contractor supervisors and HSE Engineer/Safety Officer ensure that the subcontractor's personnel comply with the rules on wearing PPE as defined in the site H&S Plan. 7 ALLOWING FOR H&S IN EQUIPMENT 7.1 Identification of work equipment Main work equipment is identified individually by its brand, model and serial number in order to be able to monitor it. 7.2 Maintenance of work equipment Maintenance of work equipment is performed by the Subcontractor’s mechanic or by an outside organization, under the responsibility of the Subcontractor who owns/rents the equipment. 7.3 Inspection of work equipment Regular inspection of work equipment is under the responsibility of the Subcontractor who owns/rents the equipment. Before any use of the equipment, the operator checks the general condition of the equipment he/she operates and notifies his/her supervisor of any anomaly as per Particular Management Procedure AVJ-A000-HS-PMP- 0010 “Equipment Control”. When bringing a new piece of heavy equipment, each Subcontractor must inform the Contractor about it. This heavy equipment must be jointly inspected by the Subcontractor supervisor and a member of the Contractor H&S Department. This inspection is recorded on a specific inspection checklist and filed in the H&S Department. 7.4 Use and operation of work equipment Before using any equipment, the operator must be aware of the recommendations relating to the equipment's operation as well as health and safety precautions. These recommendations are discussed during induction and reminded as necessary during tool box meetings. Equipment which may involve serious health or safety risks when manoeuvring may only be used by qualified personnel having received special authorization as per dispositions of the Work permit and authorization procedure. All equipment with strict requirements on occupational safety (including lightning arrest system) need to have appropriate certificate of safety inspection following the requirements in the Decree 44/2016/ND-CP and the Circular 16/2017/TT-BLDTBXH MANAGEMENT PLAN Ref: AVJ-A000-QA-PLA-0002 Rev.

E DESIGN, BUILD AND OPERATION OF BUSINESS CONTINUITY PLAN Date 2021-10-01 THE NLTN WWTP, HCMC Page 3 / 23 1 SUBJECT - FIELD OF APPLICATION The purpose of a Business Continuity Plan (BCP) is to keep the Contractor’s activity at the highest possible level while protecting exposed personnel (expatriates and locals). Depending on the risks involved, a decision to temporarily shut down the work site/offices should be considered. This guide covers the following phases: - preparing Contractor to respond to a pandemic; - in times of pandemic alert: improving response capacity and limiting the number of infected people; - in pandemic periods: to maintain economic activity and to provide our staff with the best access to means of prevention and care (if necessary). This guide can also be used to: - maintain trust within teams by coordinated, transparent and continuous communication. - define the roles and responsibilities of each person regarding the BCP in the event of a pandemic. This guide will be adapted to local contexts in accordance with the national plan in Vietnam and instructions given by French or Spanish Consulate. This guide is supplementary to VINCI or Acciona’s directives on the subject. General information on pandemic is provided in Appendix 1. 2 BCP DRAFTING AND IMPLEMENTATION Graduated responses need to be determined depending on how the pandemic evolves (see table of pandemic phases in Appendix 2). Two main scenarios are considered (according to the appropriate French national "Pandemic” plan): - an average absenteeism rate of 25% throughout the pandemic wave (8 to 12 weeks), - an absenteeism rate of 40% during the two peak weeks of the pandemic wave (absenteeism due to travel difficulties, illness, caring for family members, etc.).

E DESIGN, BUILD AND OPERATION OF BUSINESS CONTINUITY PLAN Date 2021-10-01 THE NLTN WWTP, HCMC Page 19 / 23 APPENDIX 1 - GENERAL Coronaviruses are a large family of viruses which cause illnesses ranging from the common cold (some seasonal viruses are Coronaviruses) to more severe pathologies such as MERS-COV or SARS. The virus identified in January 2020 in China is a new coronavirus. The disease caused by this Coronavirus has been named COVID-19 by the World Health Organisation - WHO. What are the symptoms of the COVID-19 coronavirus? The main symptoms are fever or feverish sensations and signs of breathing difficulties such as coughing or shortness of breath. Is there a vaccine? There is no vaccine against the COVID-19 Coronavirus at this time. Several treatments are currently being assessed in France, in conjunction with the WHO for use against the COVID-19 coronavirus. In the meantime, the treatments cover the symptoms. How is the COVID-19 coronavirus transmitted? The disease is transmitted by sputtering (sneezing, coughing). It is therefore considered that close contact with a sick person is necessary to transmit the disease: same place of residence, direct contact within less than one metre when coughing, sneezing or talking in the absence of protective measures. One of the main virus transmission vectors is contact with unwashed hands. Where did the COVID-19 coronavirus come from? The first people to contract the virus had been at the Wuhan market in China's Hubei Province. An animal- borne disease (zoonosis) is therefore privileged but the origin has not been confirmed. Has the virus mutated? According to the latest scientific data, there are indeed two circulating strains of the virus (L and S). The S strain seems to be older than the L strain. At this stage, there is no evidence to confirm whether the mutation occurred in humans or in the intermediate hosts (animal). The L strain seems be the most severe and frequent circulating strain (70% of samples tested in the study), while the S strain seems to be less aggressive and less frequent (30% of samples). Thanks to the means of detection and the measures taken against the coronavirus, the circulation of the L strain, which is more severe and therefore more easily detectable, is tending to decrease. Can you catch the disease from water? To date, there have been no reports of contamination by water. The disease is passed on by respiratory transmission and probably animal-to-human, but the source has not yet been identified. Are there any risks associated with domestic animals (farm animals and pets)? Leader COVID 19 Ref: AVJ-A000-HS-PMP-0013 Rev. E DESIGN, BUILD AND OPERATION OF BUSINESS CONTINUITY PLAN Date 2021-10-01 THE NLTN WWTP, HCMC Page 20 / 23 There is no evidence that domestic animals have a role in the spread of COVID-19, the coronavirus that causes COVID-19 (sources OIE, WHO and Anses). Are there any food-related risks? On the basis of the available information, the passage of the COVID-19 coronavirus from humans to other animal species seems at present unlikely, and the possible contamination of food of animal origin (FAO) from a COVID-19 infected animal is excluded. Raw or undercooked food does not present any particular risk of transmission of infection, provided that usual good hygiene practices are followed when handling and preparing the food. Are some people more at risk? As with many infectious diseases, people with chronic illnesses (hypertension, diabetes), the elderly (over 70 years of age), immune-deficient or frail people are at higher risk. In more severe cases, the disease can be fatal. What is the incubation period of the disease? The incubation period is the period between contamination and the appearance of the first symptoms. The incubation period for the COVID-19 coronavirus is usually 3 to 5 days, however, it can extend to 22 days. During this period the subject can be contagious. Where are the tests done and how long does it take for a diagnosis? COVID-19 coronavirus testing is carried out in all reference health care facilities, several thousand can be carried out every day. The test is used in case of suspicion of the disease, validated by paramedics and by a referring infectious disease specialist. This is a specific biology test for the COVID-19 Coronavirus. The time needed to get a result is between three and five hours. What is a Reference Health Facility? Reference health facilities are the referral hospitals at the regional level. They are designated according to specific reception capacities and the human and technical resources at their disposal: • emergency medical assistance service (this is the zone ambulance service) • accident and emergency department • infectious disease department with negative pressure isolation rooms • intensive care unit with isolation rooms • paediatric department with negative pressure isolation rooms • nuclear medicine department • laboratory with an L3 containment level • helicopter landing pad.

What is a community transmission case? A community transmission case is a person who develops the disease and for whom there is no notion of travel to a risk area. What is a contact case? The COVID-19 coronavirus is transmitted by droplets emitted by a sick person, especially during close contact. You are considered a "contact case", for example, if you shared the same living space as the sick patient when they had symptoms, if you had direct face-to-face contact within less than one metre of the sick patient when coughing, sneezing or during a discussion, if you are a direct neighbour of the sick subject on a plane or train, or if you stayed in a confined space with them (e.g. a private car) for more than 15 minutes. Symptoms can appear up to 14 days after this contact, and most often appear as fever, accompanied by a cough. Leader COVID 19 Ref: AVJ-A000-HS-PMP-0013 Rev.

In order to optimal solid waste management, all waste is classified from the source follow the hierarchy pyramid of Figure 2. Treated Recycle Reuse Figure 2: Waste Hierarchy Pyramid PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-E-PMP-0002 Rev. A WASTE MANAGEMENT Date 2020-08-10 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 9 / 20 Effective planning and implementation of waste management strategies should review of new waste sources during planning and design activities, including during equipment modification and process alteration, to identify waste generation, pollution prevention opportunities, and necessary treatment, storage and disposal infrastructure. Within the scope of this procedure, the definition of opportunities for sources reuse, recycling, controls for on site storage or treatment and final disposal during the construction phase are summary in the table following: Table 1: Identify and Evaluate Waste Method of Treatment No Construction Activities Generated Waste Reuse Recycle Treated Disposed 1 Site clearing and grabbing Vegetation waste x 2 Topsoil removal Topsoil and mud x 3 Sand backfilling Sediment after settling x process 4 Dredge bed river Slurry in river x x 5 Excavation /Sedimentation Soil and mud x X (If tests X Pond mud positive with hazardous substances) 6 Set up facility on site Scrap, paper, wood, plastic… x 7 The domestic waste from Food, water bottles, … x workers 8 Waste from toilet on site Wastewater and excrement x 9 Hazardous waste Oily rags, fluorescent light x bulbs, batteries, chemical bottles, print cartridge 4.2 Waste Prevention Purpose of the Contractor is design and operate to prevent or minimize the quantities of wastes generated and hazards associated with the wastes generated in accordance with the following strategy:  Substituting raw materials or inputs with less hazardous or toxic materials, or with those where processing generates lower waste volumes;  Instituting procurement measures that recognize opportunities to return usable materials such as containers and which prevents the over ordering of materials; PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-E-PMP-0002 Rev. A WASTE MANAGEMENT Date 2020-08-10 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 10 / 20  Instituting good housekeeping and operating practices, including inventory control to reduce the amount of waste resulting from materials that are out of date, off specification, contaminated, damaged, or excess to plant needs;  Application of measures of resources and energy save; use the natural resources, renewable energy and products, raw materials, clean energy that are environment friendly; carried out the measure to control waste to prevent and minimize waste generation;  The application of waste treatment technologies that are environmentally friendly is encouraged. The use of bio-products in waste treatment or foliar acting herbicide to keep free of weeds for the topsoil stock-piles must comply with the law.  Waste bin will be used to separate the empty plastic bottles, aluminum cans, food waste, other domestic waste. Segregated waste must be collected by a subcontractor authorized and must be recycled or treated. Bins must be color coded and be self-closing. 4.3 Recycling and reuse After identifying and evaluate waste base on its physical, chemical and biological characteristics the Contractor will carry out the proper management for each type of waste. Based on the approved EIA of the Project and CESMP of the Contractor all the waste can be recycled and reused which are listed as following:  Topsoil is used to make the boundary attend to the sand backfilling. After finished this item work topsoil will be stockpiled in the agreement areas on site in compliance with Employer’s Requirements Item 2.3.10; Then topsoil will be used to cover on the top of ground for landscape as design of project.  Wood can be reused for many purposes such as fuel use, for people who use as fuel wood and fences;  Paper, plastic bottles, iron scraps can be collected and recycled by the recycling plant;  Soil from excavation or slurry from the dredging Ky Ha riverbed can be reuse for some work in project construction site or back filling foundation the other construction site based on the Circular 082017/TT-BXD dated 16 May 2017 regarding Construction solid waste management and Decree 38/2015/ND-CP dated 24 April 2015 regarding Management of waste and discarded material. This mud is taken sample to ensure that it is not contaminated heavy metal or pollution parameters before reuse or discharge. Beside the reusing and recycling waste, the wastes are generated on site will be treated by appropriate methods according the regulations for each type of waste. 4.4 Treatment and disposal All waste materials are generated after implementation of feasible waste prevention, reduction, reuse, recovery and recycling measures, waste materials should be treated and disposed of and all measures should be taken to avoid potential impacts to workers health and the local environment. Treatment method should be consistent with the PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-E-PMP-0002 Rev.

All layers from the surface to a depth of about 40m (Soil layer 1) according to geological surveys have relatively similar properties, with the main components being Quartz and clay (Figure 6). PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-E-PMP-0002 Rev. A WASTE MANAGEMENT Date 2020-08-10 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 14 / 20 Figure 6: Soil composition in Platform area (4-34m) The excavated materials during construction include: • About 91,246m³ for mass excavation of the WWTP buildings; of which 58,376m³ will be sand, and about 32,870 m³ of soil of layer 1 • About 4000m3 excavated materials from bored piles works. Bentonite will be used during excavation. • About 4500 m3 excavated soil from D-wall works. Bentonite will be used during excavation. • About 40.000 m3 excavated soil from networks construction. The excavated sand will be reused for backfilling On the other hand, when carrying out excavation work during the construction phase, for some areas where bentonite is used, the Contractor will take 01 representative sample because this is the area with the highest risk of causing pollution. The use of bentonite, according to research, can increase pH of the soil, so the contractor will take samples including the criteria as shown in Table 2 (pH, Heavy metals, and some organic indicators) to compare with QCVN 07:2009/BTNMT. PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-E-PMP-0002 Rev. A WASTE MANAGEMENT Date 2020-08-10 DESIGN, BUILD AND OPERATION OF THE NLTN WWTP, HCMC Page 15 / 20 If it does not meet the standard, this volume of soil (about 9,500 m3) will be collected and treated by Saigon Green Company at the Da Phuoc landfill. While waiting for collection, this soil volume will be stored in an internal disposal area and covered by tarpaulin. A sedimentation pond with waterproof tarpaulin at the bottom will also be available to collect water leakage from disposal area. The excavated material which does not meet the standard because of bentonite will be collected by Green Saigon Company. Green Saigon Company has a bentonite sludge treatment capacity of 800 m3/day and the maximum capacity of the plant is 2600 m3/day. The Company can fully handle the collection and treatment of hazardous waste sludge volume of the Project, if any. If the soil sample is confirmed to be non-polluted, it will be stored at the internal disposal sites within the project. This area will also be covered to prevent oxidation and connected a standard sedimentation pond will be arranged to drain the area. Similarly, setting mud and sludge in sedimentation ponds will be handled the same way as excavated materials. 5. TRANSPORTATION AND MONITORING 5.1 Transportation On-site and off-site transportation of waste should be conducted so as to prevent or minimize spills, releases, and exposures to employees and the public. Each type of waste will be satisfied the requirement as detail:  Vegetable waste can be transported by waterway by barges or by trucks on road. All waste containers designated for off site shipment should be secured and labeled with the contents, be properly loaded, cover on the transport vehicles before leaving the site.  Domestic waste and toilet wastewater, hazardous waste will be transport by specialize truck by the license waste treatment company who sign contract with Subcontractor/Contractor.  Material such as soil or mud, after testing samples to ensure that it does not contain the pollution parameters will be reused in the other construction site, otherwise it will be transported for treatment by trucks/barge with cover, do not over-load to avoid soil and mud fall-down on the road/river. All trucks before leaving out of construction site should be washed the wheels to avoid bring soil from site to the roads. 5.2 Monitoring Monitoring activities associated with the management of waste should include:  Regular visual inspection of all waste storage collection and storage areas for evidence of accidental releases and to verify that wastes are property labeled and stored;  Inspection of vessels for leaks, drips or other indications of loss;  Regular audits of waste segregation and collection practices;  Tracking of waste generation trends by type and amount of waste generated, preferably by facility departments; PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-E-PMP-0002 Rev.

A FUEL BUNKERING Date 2021-03-25 Page 7 / 12 6.3 Dispensing fuel  On site • All dispensing or transferring of fuel will be attended for the duration of the operation. The attendant must be aware of proper fuel handling procedures to minimize the risk of a spill and shall continuously scan the area adjacent to the fueling operation for possible leaks or spills. • The transferring and dispensing of fuel will be done with pumping equipment, an approved hose, and top-fill nozzle or by hand. • When fueling absorbent pads are to be placed around the fuel inlet prior to dispensing. • Ensure that a site-appropriate spill containment kit is readily available. • Verify that there is a proper connection between the fuel fill hose and the fill pipe of the tank, mobile refueling tank, or the equipment being filled. Verify that the fill valve is open. • The transfer of fuel must be stopped prior to overflowing, leaving room for expansion. Mobile refueling tanks and fuel tanks on vehicles and equipment are not to be overfilled. • The operation of moving equipment in the immediate area of a fueling operation shall be suspended. • Welding and/or burning operations within 3 meters must be stopped while fueling is in progress. • Maintain regular inspections of fuel systems and their components. Check for leakage, deterioration, or damage, in accordance with the Construction Regulation. • Required to have two people do the job. Picture 4: Dispensing fuel on site  Marine operations At a barge/boat, product shall not be dispensed to fuel a watercraft while PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-HS-PMP-0022 Rev. A FUEL BUNKERING Date 2021-03-25 Page 8 / 12 • barge/boat does not comply with 42/2020/ND-CP dated April 08th 2020 decree on list of dangerous goods, transport of dangerous goods by land motor vehicles and transport of dangerous goods by inland waterways • its engine is running; • any source of ignition is present within 3 m of the dispensing nozzle where it enters the tank to be refueled; and • there is a source of ignition on board the watercraft being refueled. • All fuel supplies boat must be carefully checked and ensure that boat in good condition by specialized person of fuel supplier. Besides, these boats will be random checked by Contractor/ subcontractors in site. Portable containers shall not be filled while located on a watercraft • Fuel must only ever be decanted into, and used from, approved, labelled containers. • Fuel containers should not be overfilled – ideally there should be a gap of 10% of the total container height from the top of the stored fuel surface to the top of the container. When fuel gets warm some of the liquid will turn into vapour and this will make the container expand. • Petrol should only be stored in containers with the correct lid which must always be tightly fastened. • Petrol containers must not be left in direct sunlight or in the boot of a car and should be stored in a cool place. • Containers of fuel, must be secure when transported. • Secure barge or marine vessel on which the equipment to be fueled is mounted to the work platform or wharf with proper marine lines. • Prior to transferring fuel to a mobile refueling tank on a barge or to barge-mounted equipment, establish direct communication between the fuel tank operator or mobile fueling attendant and the marine operator. This shall be maintained until fueling is complete. • Where it is necessary to transfer a mobile fueling tank from the wharf or work platform to a barge, or from one barge to another, the tank shall be engineered for lifting and equipped with proper lifting points and lifting tackle. The transfer shall be done with hoisting equipment in accordance with normal safety procedures. • During marine fueling operations, the attendant shall be particularly vigilant in scanning the water area adjacent to the fueling operation for possible leaks or spills. Picture 5: Barge/boat delivery fuel 7 SITE SIGNAGE AND DOCUMENTATION When a site has petrol or diesel storage the contractor must ensure appropriate signs are in place to notify workers, public and emergency services of the presence of fuel. Signs must be at least A3 in size and display: PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-HS-PMP-0022 Rev. A FUEL BUNKERING Date 2021-03-25 Page 9 / 12 • Information about the hazardous mature of the fuel stored • Information about ignition sources and how to ensure safety of stored fuel • Information about contacts for emergency situations Storage of petrol/diesel requires that the substance is stored safely, consistent with the hazardous substances legislation. Storage of petrol or diesel requires storage in a secure and locked facility. Picture 6: Fire-fighting equipment for fuel on site Picture 7: Signage for fuel storage 8 TRAINING Workers who are required to use fuel storage tanks must be properly trained to: • Use the storage system correctly • Understand the potential hazards when using the storage facility • Implement correct safety controls, including use of PPE • Respond in case of emergency 9 EMERGENCY RESPONSE The ERP will follow AVJ-A000-HS-PMP-0006: “EMERGENCY MEASURES”, section 10 “ACCIDENTAL POLLUTION – SPILLS”. 9.1 Key steps Emergency spill response involves the following key steps: PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-HS-PMP-0022 Rev. A FUEL BUNKERING Date 2021-03-25 Page 10 / 12 a. Containment Spills involving hazardous materials should first be contained to prevent spread of the material to other areas. This may involve the use of temporary diking, sand bags, dry sand, earth or proprietary booms / absorbent pads. Materials or covers to plug or block drains may also be required. Picture 8: Absorbent pads If the accidental spill happens on river, the containment must be done in the same way Picture 9: Emergency response b. Fire prevention Where there is a spillage of flammable material, instructions to prevent fire and explosion by isolating or switching off electrical equipment must be available to emergency response teams. PARTICULAR MANAGEMENT PROCEDURE Ref: AVJ-A000-HS-PMP-0022 Rev. A FUEL BUNKERING Date 2021-03-25 Page 11 / 12 c. Prevent further loss of product To prevent the further loss of product ,removal of product from a leaking tank should be done, second tank/container should be back-up. d. Render safe Once the hazardous material has been contained to prevent spread of the material to other areas, the material should be treated wherever possible to render it safe. Due to the differing properties of the various groups of chemical, an appropriate treatment strategy with suitable chemicals should be established in each case (reference should be made to appropriate MSDS). e. Clean up Oil or fuel should be absorbed onto inert carrier material (ether sand or proprietary absorbent) to allow the material to be cleared up and removed to a safe place for disposal or further treatment as appropriate 9.2 Spill control materials SDSs for all materials and chemicals on site should be reviewed to ensure appropriate clean up materials are made available. Sufficient quantities and types of spill control equipment and materials to contain any spills should be stored and made available on site. Testing and inspection of spill control equipment and materials shall be implemented periodically. All spill control materials and absorbed chemicals, fuel, oils or other materials should be collected and contained prior to safe disposal. Following clean-up of spills decontamination of the area may be required. 9.3 Drainage systems Where there is a risk of spillages and where such spillages may enter drainage systems and discharge to the environment oil separators should be installed. Use of separators should be considered on construction sites, temporary storage areas, vehicle maintenance areas etc. where spills are more likely although at such sites volumes of spilt material would not be expected to be high due to lower inventory volumes of fuel, oils or chemicals kept on site. 9.4 Personal Protective Equipment All personnel involved in handling chemicals, fuels, oils and other materials and those involved in clean-up of spills must be provided with appropriate PPE. Reference should also be made to MSDSs of materials on site to ensure additional special PPE may be required (e.g. acid resistant clothing, masks etc.).
