I. INTRODUCTION

The Productive Rural Infrastructure Development Project in the Central Highlands (hereafter

referred to as “The project”) is funded by loan from the Asian Development Bank (ADB), and

Ministry of Agriculture and Rural Development (MARD) is the project owner. The project will be

implemented within 05 years (2014 – 2019) and taken place in the 05 provinces of the Central

Highlands (Lam Dong, Dak Nong, Lam Dong, Gia Lai and Kon Tum).

The long-term purpose of the project is to contribute to hungry alleviation and poverty

reduction programs of the Government through sustainable development of the society, ecology,

and environment at community levels by developing infrastructures for production, improving socio-

economic conditions and living standards of people in the area.

The short-term objectives of the project are (i) to rehabilitate and upgrade deteriorated or

damaged irrigation systems and rural infrastructures, which are serving for production in 05

provinces of Highlands; (ii) To strengthen management capacity and implementation of ODA

projects; strengthen infrastructure management at community, province, district, and commune

levels to gradually improve living standards and conditions of the poor in the project area in the

Central Highlands; (iii) To build models, institutional policies on "water saving irrigation technology

for strategic and economic valuable plants" and "management and exploitation of irrigation

schemes sustainably with the participation of all economic sectors”.

One sub-project of The Project is “Reinforcing Da Don irrigation works, Lam Ha district, Lam

Dong province”, which is taken place in Da Don, Tan Van communes, Dinh Van town - Lam Ha

district, and Binh Thanh commune – Duc Trong district, Lam Dong province. The sub-project area

is about 45 km from Da Lat City. The objectives of this sub-project are: to improve livelihood and

life quality of people within the area, promote socio-economic development by investing and

promoting the effectiveness of rural infrastructure; to facilitate people to have access to and apply

scientific and technical advances in agricultural production, increase productivity and diversification

in agriculture; to bring job opportunities; alleviate poverty, actively contribute to the New rural

program and socio-economic development strategy of the locality through investment in subproject.

The objectives and scope of this Initial Environmental Examination (IEE) are to (i) assess

the existing environmental conditions along and in the vicinity of the sub-project; (ii) identify

potential environmental impacts from the proposed components; (iii) evaluate and determine the

significance of the impacts; (iv) develop an environmental management plan (EMP) detailing

mitigation measures, monitoring activities, reporting requirements, institutional responsibilities and

cost estimates to address adverse environmental impacts; and (v) carry-out public consultations to

documentary issues/concerns that stakeholders may have on the sub-project and to ensure that

such concerns are addressed in the sub-project design and mitigation measures.

This IEE of the sub-project is prepared to meet the requirements of environmental safety of

ADB and the environmental regulations of Government of Vietnam. Its structure includes 11 parts

as following:

(i) Introduction

II. POLICY FRAMEWORK, LEGISLATION AND MANAGEMENT

2.1 ADB policy

The 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 guides in identifying type of environmental report that will be implemented

through Rapid Environment Assessment (REA), type of project, and preparing appropriate

environmental report. The SPS emphasizes the need of effective implementation of mitigation

measures to:

i. Avoid adverse impacts of projects on the environment and affected people, where possible;

ii. Minimize/mitigate and/or compensate for adverse impacts on the 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 2009 requires preparing environmental assessment report 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 phase of the project.

Moreover, all subprojects under the loan 3032-VIE need to follow the specific guidance on

environmental assessments 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 “Reinforcing Da Don irrigation works, Lam Ha district, Lam Dong province” is

selected based on the project’s EARF that may cause some adverse impacts on the environment

that could be mitigated and ranked as categorized B. Therefore, an IEE needs to be prepared with

an EMP enclosed.

V. ENVIRONMENTAL IMPACT SCREENING

5.1 Positive impacts

The subproject "Reinforcing Da Don irrigation works, Lam Ha district, Lam Dong province"

will bring positive impacts on environment and society as follows:

- It will ensure safety for works; reduce the loss of water in canals due to penetration; save

water for irrigation; take the maximum advantageous of water resources from the reservoirs

to increase the area of irrigated plants, especially during dry season; ensure growing of

plants and trees as well as domestic water supply, aquaculture activities of the local people.

It will also contribute to stabilization of groundwater resources;



23

- The development of rural road infrastructure improves traffic and links residential areas to

production areas reducing burden and cost in transporting materials, fertilizers and

agricultural products, transport of people will be more favorable during rainy and flood days.

It also creates favorable conditions for mechanizing agricultural production, brings scientific

advances into the producing areas that will increase crop yields. The sub-project also

reduces cultivation and labor costs and improves income of local people in the sub-project

area.

- The sub-project will also contribute to improvement of living conditions, livelihoods, and

environment in the sub-project areas and therefore could potentially reduce poverty. The

sub-project is expected to bring long-term benefit for 1,432 ha of 2-crop rice, 686 ha of

coffee, 82 ha of crops of Da Don irrigation system.

5.2 Negative impacts

Besides positive impacts, the implementation of sub-project could also create several

negative impacts, especially during construction phase, which need to be managed through

appropriate mitigation measures. The negative impacts from sub-project could be summarized in

UXO removal activities were completed in December 2017.

UXO can be remained in the subproject areas where had been suffered from war. Unexploded items may create risks for local people and workers during construction phase. However, UXO removal activities were carried out by 319 Corporation Ministry of National Defense & completed in September 2017. (please see details in annex 6)

2 Impacts on HHs due to site clearance (land acquisition)

Yes Minor Negative Temporary Description:

Roads and canals will be constructed on existing ones without extension. Thus site clearance is not implemented

- 1 material yard is of Construction Company and being exploited, so there is no acquisition of local people’s land.

- Land for storage area, camp, gathering materials is taken from land along the road, the area is about 10,000 m2.

(Source: Statistics on affected land from preliminary survey of Lam Dong PPMU, Subproject Investment Report)

Affected object(s): Local people whose productive land is near material yard, camps, storage area.

Affected level: This impact is minor due to there is no permanently land acquisition.

Location: Production fields of HHs along the upgraded road, canals and irrigation works

Time: Temporary.

3 Reducing crop productive due to inappropriate construction plan in term of time

Yes Moderate Negative Temporary Description: Wet-rice is main crop, which is irrigated by irrigation system of Da Don reservoir. There are 02 main seasons including Winter-Spring and Summer- Autumn. The construction period will be in 6 months, which could stop temporarily irrigation flows on upgraded canals and cause reduction of water availability for agricultural crops. The possible consequences will be negative impacts on agricultural productive and livelihood of local people. Thus,

� Local people in Da Don and Tan Van communes and Dinh Van town.

Affected level: The impact is moderate due to i) the construction of canals has to be mainly implemented in the dry season – at the same period of agricultural activities and plants needed to irrigate water during dry season; ii) the construction of each canal will be 10-15 days, thus impact on water availability for agricultural crops will be insignificant; iii) construction of canals and road will be implemented section by section which could help reduce interruption period.

Location: Construction sites on canals, roads, downstream area of Da Don weir, where irrigated by main canal, 03 grade-I canals and other lower-grade canals in Da Don and Tan Van communes and Dinh Van town.

Time: Temporary during preparation and construction phases.

II Construction phase

1 Landslide, soil erosion or sedimentation flow into irrigation canals, drains

Yes Minor Negative Temporary Description: The constructions activities, especially excavation, embankment and storing materials in head-works of Da Don weir as well as upgraded canals, and upgraded roads could create debris and/or cause materials falling into water sources. Soil erosion and landslide could cause increasing in sediments and turbidity of surface water as well as obstructing water flows. The consequence could cause negative impacts on the rice fields located near by the construction sites in Da Don and Tan Van communes and Dinh Van town. The highest risks location of landslide and soil erosion could be listed as below:

� Soil erosion caused by the excavation of canal bed and slopes along upgraded canals and upgraded roads.

� Fields/crops irrigated by canals of the subproject;

� Cultivated areas, which located close to the 01 borrow pit.( Yen Thanh Village-Da Don Commune)

� Beneficiaries on the closed proposed canals and roads areas.

Affected level: This impact is moderate due to (i) the material sources are mainly taken from agreed borrow pit of Da Don commune; (ii) volumes of excavation and embankment are not much (total excavated soil: 10,314 m3; total embanked soil: 5712 m3); (iii) the excavated soil will be reused to fill up banks of upgraded main canal and roads in Da Don and Tan Van communes and Dinh Van town; (iv) excavation activities will be mainly taken during dry season and (v) borrow pit is located in the vacant land. However, this impact still needs to be managed and controlled to reduce surface water pollution.

Location: Sloping area of Da Don weir, slope and road within the subproject area in Da Don and Tan Van communes and Dinh Van town.

Time: This impact is temporary during the constructing phase.

2 Surface water pollution

Yes Moderate Negative Temporary Description: Surface water sources including Da Dang river, Cam Ly stream, Da Me stream, Da SeDang, Da K’Nang streams and other small streams as well as ditches, irrigation canals within subproject area could be polluted due to construction activities. The main sources of pollution include (i) domestic wastewater of workers in 02 camps; (ii) grease and oil from machinery maintenance and (iii) rainwater runoff passing through constructional areas/activities during rainy days; (iv) spoils and/or sediment from excavation, embankment as well as materials. Such pollutants could fall into water resources causing water pollution, reducing quality of irrigation water, domestic water as well as causing impacts on aqua-ecosystem with the subproject area.

scattered in 2 camps (about 5m3/day within subproject area), wastewater generated from machines is less, machines generates less wastewater, less oil and grease, number of materials falling into water sources on rainy days is minor. Moreover, construction of head-works will be implemented in dry season, thus impacts are minor and controllable.

Affected object(s): Surface water sources including Da Dang river, Cam Ly stream, Da Me stream, Da SeDang, Da K’Nang streams and other small streams as well as ditches, irrigation canals within the subproject area.

Affected level: The impact level is moderate due to (i) the construction activities will be scattered in the large areas, 02 camps will be located at difference places, few workers will be mobilized on the sites (estimated 50 at maximum); (ii) excavation will be taken section by section and (iii) generations of domestic wastewater (less than 5 m3/day), grease and engines oil are limited. However, appropriate mitigations need to be implemented and monitored to minimize the impacts.

Location: Da Dang river, Cam Ly stream, Da Me stream, Da SeDang, Da K’Nang streams and other small streams as well as ditches, irrigation canals within subproject area.

Time: This impact is temporary during the construction period.

3 Noise and vibration from construction machines and trucks

Yes Minor Negative Temporary Description: Upgrading dams, roads, canals of the sub-project will cause noise and vibration from construction machines (concrete mixers, bulldozers, stream rollers, trucks, etc.) that may affect residential areas along the upgraded roads/works. In addition, the exploitation of soil & disposal of soil as well as construction waste in borrow pit and disposal site will create noise and vibrations.

Affected object(s):

- Residential areas closed to Da Don weir, upgraded roads and canals in Tan Van, Da Don communes, Dinh Van town;

- Residential areas along main transportation roads of the sub-project in Tan Van, Da Don communes, Dinh Van town;

4 Air pollution (dust and exhaust)

Yes Minor Negative Temporary Description: Dust, air pollutants will be generated from excavation activities, waste disposal activities, electrical generators, mobile concrete mixers or operation of trucks, material storage areas, especially on sunny days. However, the main air pollutants such as NOx, CO, SO2, etc. will be minor since the number of construction equipment mobilized on the site will be minor and scattered in the large areas of construction sites. In addition, construction area is far from residential area. People travelling on this route are not much. A small part of soil will be utilized by local people, which could generate dust when transporting, however, each HH just uses a small volume of soil so the dust is not significant.

Affected object(s):

- Residential areas closed to Da Don weir, upgraded roads and canals in Tan Van, Da Don communes, Dinh Van town;

- Residential areas along main transportation roads of the sub-project in Tan Van, Da Don communes, Dinh Van town;

- Residential area closed to 01 borrow pit and 01 disposal site;

- Workers at 02 camps.

Affected level: This impact is minor, due to (i) the excavation activities schedule to be implemented during dry season; (ii) very few equipment will be mobilized, (iii) no HH is located along the borrow pit and disposal site (iv) very few households are located along the updated canals and roads; (v) subproject areas are located in rural areas where have many opened space for pollutants to dilute.

6.3 Capacity Building for EMP implementation

The relevant stakeholders need to ensure the EMP implementation as their responsibilities. All CPMU, Lam Dong PPMU, CSC and CC need

to appoint officials/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.

- Lam Dong PPMU 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 (CC): will be trained (immediately after signing contract) on implementing mitigation measures and preparing reports.

IX. GRIEVANCE REDRESS MECHANISM

9.1 Purpose of the mechanism

During the implementation of the subproject, local people are informed of environmental

protection activities described in EMP. Negative impacts on the environment may occur during the

construction and operational phases. Any comments / grievances of local people will be solved

quickly, transparently and in compliance of laws, particularly for affected people by the sub-project.

Grievance redress 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 grievance as

below:

Stage 1: If a household has any grievance, he/she can submit it to the CPC-community

monitoring board. CPC will work with CSC and CC to solve it.

Stage 2: If the grievance is not redressed, it will be submitted to the Lam Ha DPC to

redress. Lam Ha DPC (through Lam Ha DONRE) will work with PPMU to solve it.

Stage 3: If more than 15 days pass without response from Lam Ha DPC, the complainant

may submit a grievance to the Lam Dong PPC (through Lam Dong DONRE). Lam Dong PPC will

require Lam Ha DPC to solve it. In case the grievance is still not redressed, Lam Dong PPC will

require environmental police to investigate and requested stakeholders to solve it. See the

mechanism in figure below:

Figure 3: Grievance redresses mechanism

X. CONCLUSION, COMMITMENTS AND RECOMMENDATIONS

10.1 Conclusion

The results of environmental screening and environmental impact assessment show that

the sub-project may cause some environmental impacts but most of such impacts are minor to

moderate. However, the appropriate mitigation measures have also proposed to manage the

negative impacts and maximize the benefit of the subproject. The responsibilities of implementation

and monitoring of the stakeholders have also identified in this IEE report to ensure environmental

compliance.

10.2 Commitments

Lam Dong PPMU of the subproject “Reinforcing Da Don irrigation works, Lam Ha district,

Lam Dong province” commits themselves to:

- Implement requirements of environmental safety as stated in IEE via information

dissemination, integrating environmental safety as stated in this IEE in bidding documents,

in construction and in the CSC contracts; mobilize human resources and monitor internally

the IEE compliance;

- Report environmental management plan implementation to Lam Dong DONRE and CPMU

periodically as specified in the IEE;

- Compensate and take measures against environmental pollution if there is any problem

during operational phase of the sub-project;

- Redress grievances if any.

10.3 Recommendations

Based on the IEE report, the Lam Dong PPMU would recommend that:

- No further environmental assessment is needed because the impacts on environment is

temporary, minor or insignificant, when application of mitigation measures during the

construction phase.

- Based on IEE, Lam Dong PPMU would like to request functional authorities to appraise and

approve the IEE for “Reinforcing Da Don irrigation works, Lam Ha district, Lam Dong

province” sub-project to create the basic for next implementation steps, ensure the

implementation progress, effectiveness and benefits of the subproject.
