II. POLICY FRAMEWORK, LEGISLATION AND MANAGEMENT 2.1 ADB policy ADB Safeguard Policy Statement (SPS) 2009 imposes safeguard requirements for all its funded projects. The SPS 2009 clarifies reasons, scope and contents of the environmental assessment. The SPS emphasizes on environmental and social sustainability in progress of economic growth and poverty reduction in Asia and the Pacific, therefore, the objectives of SPS focus on: i. Avoid adverse impacts of projects on the environment and affected people, where possible; ii. Minimize/mitigate and/or compensate for adverse impacts on environment and affected people when avoidance is not possible; and iii. Help borrowers/clients to strengthen their safeguard systems and develop the capacity to manage environmental and social risks. The SPS requires preparing environmental safeguard document in the process of preparing a project including environmental management plan (EMP). The borrower/client needs to monitor EMP implementation. The monitoring will identify outstanding issues of EMP implementation and propose appropriate mitigation measures. Periodic monitoring reports on EMP activities will be submitted to ADB every semi-annual during construction of the project. Moreover, all subprojects under the loan 3032-VIE need to follow the specific guidance on environmental assessment as stated in the Environmental Assessment Review Framework (EARF) of the project, prepared by the project owner and approved by ADB. The subprojects under loan 3032-VIE only categorized as Category B or C will be included in the list of eligible sub-projects for possible funding under the proposed Project. It is anticipated that all eligible sub-projects will fall into Category B, whereby some adverse environmental impacts are expected, but of a lesser. The subproject “Repairing, upgrading Di Linh western and eastern reservoirs, flood bypass of Ka La reservoir and productive rural infrastructure in Di Linh district, Lam Dong province” is selected based on the project’s EARF that may cause the insignificant environmental impacts to the environment and ranked as categorized B. Therefore, an IEE needs to be prepared with an EMP enclosed. 2.2 Environment regulations of Vietnam government The project must also comply with the environmental regulations. The Vietnam legal framework comprises of the following items: - The Law on Environmental Protection adopted by the National Assembly of the Socialist Republic of Vietnam dated January 01, 2015.

DATA ITEM SUBPROJECT DATA subproject area is still good. ( dust =0.018-0.026 mg/l) The noise and vibration pollution was observed at the locations which are close to high traffic volume and agricultural product processing manufactures. But all of them are located far from subproject location. As monitored results of 5 location of Di Linh Division of Environmental and Natural Resource, show that noise and vibration level is much lower allowed Noise and vibration value in national standard. Additionally, 6 samples have been collected and analyzed during EIA preparation (Dec 2015) as the same air quality monitoring locations, and the result indicated noise level of the subproject area is acceptable as much lower than allowed limits by QCVN 26:2010/BTNMT (See more details in Annex 4b). The subproject area is influenced by the tropical monsoon and plateau tropical monsoon climate. The climate is divided into two distinct seasons: - The rainy season is from May to November (accounting for approximately 80-90% of annual rainfall that on average is 1553 mm). - The dry season is from December to April (accounting for approximately 10% to 20% of annual rainfall). According to meteorological data from Bao Loc station: Temperature of these areas as follows: ° Average annual temperature: 20 - 210C ° The highest temperature: 30 - 310C (May, June, July) ° The lowest temperature: 100C (Dec., Jan.., Feb.) Air humidity: ° Humidity average /year: 86% ° The highest humidity month: 90-92% (June – Sept.) ° The lowest humidity month: 79 – 83% (Jan. – Apr.) Sunshine hours: Climate and natural ° Annual average number of sunshine hours is above 2,330 hours and disasters mostly in the dry season (Dec. – April) and fewer sunshine hours in the rainy season (May – Nov.); ° The highest number of sunshine hours per month is 260 hours. ° The lowest number of sunshine hours per month is 132 hours. Wind: wind in area is depended on season and have two types of wind one directed Northeast and the other South-west. ° Average wind speed is 2.3m /s; ° The maximum speed is 28 m/s; Natural Disasters: Main natural hazards in the Central Highlands and in Lam Dong province consist substantially of droughts in the dry season, floods & flashfloods in the rainy season. Other occasional hazards occurred in the past, such as landslides, extreme wind, hail, extreme rainfall and extreme hot days. Because of the geographical location of the Highlands Region, directly impact of tropical storms in Lam Dong province, including Di Linh district, is low. However, tropical storms in East Sea have had some negative impacts on local climate and caused some extreme rainfalls such as in years of 1987, 1994, 1999 and 2000; The extreme rainfalls with high intensity caused landslides in

DATA ITEM SUBPROJECT DATA mountainous/hilly areas such as Tan Nghia commune in 2013, 2014; Tan Thuong commune 2013 and in Da Huoai river banks 2014 etc. of Di Linh district. Droughts have occurred in Lam Dong province but with less extent than those in other Highland provinces, because of its particular microclimate. However, several droughts had been recorded in the recent past, for instance in 2002 that had a severe impact in the areas of Bao Loc, Bao Lam, Da Huoai, Da Teh, Cat Tien districts, resulting in insufficient water for irrigation. The drought in 2015 affected 217 reservoirs in Lam Dong province, including Ka La reservoir, also depriving many of such reservoirs of sufficient water for irrigation. The subproject area is dominated by plateaus and mountains covered by plantation/natural forest and the terrain are topographically complex. The main plains are mostly located along National Highway No.20 and other main roads of district. As results from geological tests, the soil in subproject area include 04 layers: (1) top layer, clay with sand & stone, organic compounds, and vegetables is Topography and from 0.3m to 0.4 m of thickness; (2) clay with brown-red sand & stone, grey- soil brown stone is from 2.5 to 5.2 m of thickness; (3) clay with a little brown-red stone, grey-brown stone is from 0.9 to 9.5 m of thickness; and (4) grey and grey-black basalt stone is from 2.5 to 11.3 m of thickness; The sub-project area has 07 soil categories: alluvial soils (1,980 ha); swampland & peat land (14 ha); grey degraded soils (2,071 ha); basalt soils (5,306 ha); yellowish red soils (117,414 ha); valley soils (1,336 ha); and humid ferrasols (27,367 ha). Surface water The surface water resources include rivers, small streams and reservoirs. resource The area is crossed by the Dariam River (length of 26.6 km); the Da Dung River (19.4 km); Dargna River (9.3 km). Reservoirs include Ka La, Ka La 2, Ka La 3, East Di Linh, West Di Linh reservoirs and Reservoir 109; etc. The above rivers are upstream of Dong Nai & La Nga Rivers and are quite rich in water; Local people are exploiting the surface water resources for both production (mainly agricultural irrigation) and domestic purposes. Surface water Ten samples of surface water had been collected in sub-project areas of 6 quality communes (Dinh Trang Thuong, Tan Chau, Hoa Ninh, Tam Bo, Dinh Lac and Gung Re) and Di Linh Town and 14 parameters have been monitored by Center of Environmental Technology. In addition, 6 other samples of surface water have been collected, analyzed 15 parameters by Vinacontrol in December 2015 during EIA preparation as per government requirements. Both results indicated that the quality of surface water in these areas is good for irrigation purpose. Most monitored values were within the standards for domestics purposes, except for Coliform value of Hoa Ninh & Gung Re and West Di Linh reservoir samples that exceed the allowed limits, as established by National Technical Regulation on surface water quality QCVN 08:2015/BTNMT of MONRE (at Hoa Ninh Commune Coliform bacteria = 24,000 MNP/100ml). (See more details in annex 4a & 4b). Groundwater in sub-project area is normally found at the depth of 3.3 m to 4.7 m. Local people exploit it for domestic purposes Underground water Two (2) samples of ground water with 5 parameters have been collected and analyzed by Vinacontrol in December 2015.

Unfortunately, no data on floods has been recorded in Di Linh. However, no households are living in flood-exposed areas of Dariam crossing Di Linh town. Terrestrial fauna The main flora in the sub-project area are agricultural crops (tea, cashew, and flora paddy, cassava, maize, beans, coffee, pepper, rubber and more.) in which, tea and coffee are the main agricultural products; Terrestrial fauna in the area includes cattle, pigs, chickens, etc.; No protected wild animal are present in the area. Aquatic fauna and Aquatic fauna and flora features could be only found in the Dariam river, its flora tributaries, small streams, Di Linh East & West reservoirs, Ka La reservoir as well as canals system of such reservoirs. However, there are no specific available data of aquatic flora and fauna of these water bodies. Through field visits, it has been learned that aquatic fauna include freshwater fish, shrimp and others, while aquatic flora include water hyacinth, algae and various other grass. No aquatic fauna & flora species are listed in the Red Data Book of Vietnam. Protected areas There is no ecological/protected area within or near the sub-project area in East and West reservoirs of Di Linh town. The Natural Reservation Area of Song Mao (Mao River) is the nearest to the subproject area, but is located as far as 35 to 40 km from Di Linh town. 4.3 ENVIRONMENTAL AND SOCIAL CONDITIONS Unexploded Checking of unexploded bombs and mines (UXO) to ensure safety during bombs, mines construction of the sub-project was completed in November 2015.

The area in southeast of Ka La flood bypass is forest plantation managed by local people in Bao Thuan commune. Residential area Residents in the sub-project area mostly inhabit the center of the near the communes, especially in Di Linh town, or in areas along the main roads. subproject The shortest distance from residential areas is 20 - 30 m (include areas along National roads No.28, No.20 and other roads of Di Linh town connecting to West & East reservoirs). While around reservoirs the closet distance from residential areas to reservoirs is about 300 – 500 m. Residential areas No.1, No.2, No.3, No.8 and No.9 are surrounding West reservoir, while residential areas No.6, No.7 and No.10 are close to East reservoir. There is no residential area close to Ka La reservoir and the flood by- pass; the nearest residential area is 1 km distant to the reservoir and the by-pass. Road network: Di Linh district has a convenient road network connecting its center (Di Linh Town) to other communes, other provinces (Dak Nong, Ninh Thuan – Binh Thuan) with National Highways No.14, No.20, No. 27 and No.28 passing through. This network creates interconnection and promotes socio-economic development. Irrigation system: The main economy of Di Linh District is agriculture, it justifies the construction of 6 reservoirs. Presently, these systems are degraded since all of them were built 30 years ago (Dong Do builtin 1964, Ka La 2 & 3 in 1974, West Di Linh in 1982, East Di Linh in 1986). Rural Capacity of these 6 reservoirs is now insufficient to serve their agricultural infrastructures areas (75% of district) and endanger the safety of local people during the flooding season. Electric Power & telecommunication: Each commune of the district has its own post office, national grid has reached all the communes of the sub- project and used by 80% of locals. Education: in 2014, 21,333 students in Di Linh attended elementary and high schools: 53.05% of them were female and 46.95% male. Health care: The district center has 01 district hospital, while each commune (17 in total) and 01 town have their own clinic center.

6.3 Building capacity for EMP implementation The relevant stakeholders need to ensure the EMP implementation as their responsibilities. All CPMU, PPMU Lam Dong, CSC and CC need to appoint officers/staffs to be in charge of environmental management. However, most of these officers/ staffs are also assigned for other works and they are not specialized in environmental management. Thus, to ensure EMP is implemented in compliance with sponsor policies and Vietnamese legislation, these officers/ staffs must be guided/ trained on EMP implementation capacity building. Training on EMP implementation must be held for different groups with different requirements. - PPMU Lam Dong and CSC: The staffs that are in charge of environment will be trained (at least once in the first 3 months of the project) on monitoring and preparing environmental reports. - Construction contractor: Will be trained (immediately after contract signing) on implementing mitigation measures and preparing reports.

IX. GRIEVANCE REDRESS MECHANISM 9.1 Purpose of the mechanism During the deployment of the subproject, local people are informed about environmental protection activities such as EMP. Negative impacts on the environment may occur during the construction and operational phases. Any comments/ suggestions of local people will be solved quickly, transparently in compliance of laws, particularly for affected people by the sub-project. Complaint handling mechanism will be classified by level and responsibilities of involved parties. 9.2 Grievance redress mechanism Per the environmental management frame, there are 03 steps to redress complaint as below: Stage 1: If a household has any complaint, he/she can submit a complaint to the CPC-community monitoring board. CPC will work with CSC and CC to solve complaints. Stage 2: If the complaint is not resolved, the complainant will submit an application to the Di Linh DPC to resolve the complaint. Stage 3: If more than 15 days pass without response from Di Linh DPC, the complainant may submit a complaint to the Lam Dong PPC (through Lam Dong DONRE). Lam Dong PPC will require Di Linh DPC to solve the complaint. In case the complaint is still not resolved, Lam Dong PPC will require environmental police to investigate and requested stakeholders to resolve the complaint. See the mechanism in figure 1 below: Figure 1: Grievance redresses mechanism
