II. POLICY FRAMEWORK, LEGISLATION AND MANAGEMENT

2.1 ADB policy

The ADB’s Safeguard Policy Statement (SPS) 2009 governs the environmental and social safeguards of ADB's operations. The SPS 2009 emphasizes on environmental and social sustainability in progress of economic growth and poverty reduction in Asia and the Pacific. The SPS environment safeguards aims 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 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.

Environmental Safeguard Requirements of the SPS outlines the requirements that borrowers/clients are required to meet when delivering environmental safeguards for projects supported by ADB. These requirements include assessing impacts, planning and managing impact mitigations, preparing environmental assessment reports, disclosing information and undertaking consultation, establishing a grievance redress mechanism (GRM), and monitoring and reporting.

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 extent.

Subproject “Repairing, upgrading productive rural infrastructure in Lac Xuan and Tu Tra communes, Don Duong 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 Category B. Therefore, an IEE needs to be prepared with an EMP enclosed.

1. New or innovating or upgrading project

Repairing and upgrading irrigation and rural road infrastructure

2. Components of the subproject

02 main components of the subproject:

(i) Irrigation component: Repairing and upgrading headwork of Tan Hien reservoir in Lac Xuan commune and Cong Doan reservoir in Tu Tra commune.

(ii) Road component: Upgrading about 9.309 km rural road surrounding productive area of the subproject in these 02 communes.

2.1. Irrigation component

1- Repairing, upgrading grade IV Tan Hien reservoir headwork:

a) Existing Tan Hien Reservoir Headwork : (i) Tan Hien reservoir was built in 2005 to supply irrigation water for 8 ha of



Page 5


paddy and 4 ha of vegetables around the reservoir. The reservoir’s capacity was about 110.36x103 m3 with its water surface area by 4.5ha. However, the current irrigation demand is 78ha of 3-crop vegetables and 30ha of 2-crop vegetables while there is no other reservoir in the area. Therefore, it is needed to upgrade Tan Hien reservoir to increase its capacity. (ii) The earth dam’s upstream slope is reinforced by concrete slabs with a layer of filter sand/gravel. In general, the slope is rather good, although it has some cavities causing seepage process in the future. (iii) The toedrain was built by masonry and currently in damaged condition causing subsidence. (iv) Downstream slope of the dam is uneven and eroded; and the grass layer has been destroyed due to cattle grazing. (v) The dam top was made of soil and gravel with a lot of sagged positions. (vi) The flood spillway is reinforced by concrete; (vii) Downstream valve gate of 300mm diameter intake is damaged.

b) Intervention actions will be done by subproject

- Level IV headwork work includes:

(i) Upgrading reservoirs

It will raise the normal water level of the reservoir dam +0.53m from +1,019.57m to + 1,020.10 m and dredges 130x103 m3 of sediment in the reservoir bed to increase the capacity of the reservoir. A new weir at 2.43km in upstream of the reservoir will be built to supplement water of the reservoir. Water from the weir will be flown to the reservoir by a D300mm pipeline with a total length of 2.43 km.

(ii) Soil dam

A homogeneous soil dam has the designed dam crest elevation is +1,020.9 m, length is L = 245 m dam width is B = 5m (combined as traffic road), the dam height is H = 6.6 m. It builds a wave wall on the crest by M200 reinforced concrete, the wall crest elevation is equal the dam crest one is +1,021.60, the wall height is 70cm. The dam has a subsidence split in each 10m. The dam crest width is 5m combined as a road. The dam surface consists of two layers. The bed layer is 20cm thick gravel, the dam surface is made of a 20cm concrete layer. The dam also has a downstream drainage. It needs to level and plant grass from the dam crest to the drainage.

(iii) Flooding spillway

It reinforces and raises the overflow threshold 0.53m, extends width of the spillway from 2m to 3m by M200 concrete

(iv) Water Intake

Pressure underground culverts are made of D300mm steel pipe culverts, steel thickness is 8mm. The pipes are covered by M200 reinforced concrete. The culverts are open and close by two downstream valves. The culvert slope i = 0.005, body length L= 28m.

(v) Main canal

It builds a new 629.35 m canal

(vi) Water pipeline from the dam to the reservoir

From water intake of the dam towards the end of the pipe is 2430m long. The steel pipe has D300mm with 5mm thick.

(vii) Items on the pipeline

On the pipeline, it installs sediment/air discharge valves. In addition, along the pipeline there will be 4 water intake valves.

(viii) Dredge the reservoir bed

The subproject will dredge the reservoir bed to the designed elevation as 1,013m. When dredging to the reservoir banks, pay attention to slope coefficient, at least, it is 1.5. The dredged length is 558m.

2- Repairing and upgrading Cong Doan reservoir headwork:

a) Existing Cong Doan Reservoir Headwork

- Cong Doan reservoir was built by local people since 1978 including an earth dam and an earth flood discharge culvert. The reservoir cannot store water any more.

- Earth dam: The top is subsided and sagged. The upstream slope is not reinforced and it is significantly eroded with some negative slope (like a frog's jaw). The downstream slope is eroded unevenly. The dam crest is made of hill gravel and used as traffic road.

- Spillway: constructed on the cut foundation and not reinforced yet;

- Water intake: unavailable


- Level IV work includes:

(i) Upgrading reservoirs

It will raise the normal water level of the reservoir dam from +1,018m to +1,018.67m, dredge 108 x103m3 of sediment of the reservoir bed so that the reservoir can store 166,930m3 instead of its impossible current status,

(ii) Soil dam

It retains the old dam and fills the dam in its upstream from the foot up to designed altitude. The two- dam blocks (the new dam block and the old block is reused) with the designed dam crest altitude is +1,020.50 m. Width of the dam surface is B = 6m (combined as a road), the dam height H is 5.9 m and length L is 330m.

(iii) Flooding spillway

It's free spillway, as a thin reinforced concrete spillway M200, on the spillway, there is a bridge used to open/close bottom discharge valves. The bridge is made of reinforced concrete.

(iv) Water Intake

The culverts combine with spillway.

(v) Dredge the reservoir bed



Page 7


It will dredge the reservoir bed to the designed altitude equal 1,014.5m, while dredging nearly the reservoir banks, pay attention the minimum roof coefficient m=2; dredged length is 293m.

2.2 Rural road component

a) Existing rural road around Tan Hien reservoir

- Roads around Tan Hien reservoir are earthen, 4,742.66 m long 3-5m wide without drainage. In the rainy season, these are divided by water flow from the mountain causing it slippery and muddy.

- The road connecting to productive area of Cong Doan reservoir in Tu Tra commune is 4,566.48 m long, 3-6m wide. The surface is eroded; the slope is not appropriate; there is no drainage ditch; it is muddy and difficult to travel in the rainy season.


Repair and upgrade 9,309.14 m of road to Class IV road (TCN210-92), including about 4,742.66 m around Tan Hien reservoir in Lac Xuan commune and 4,566.48 m around Cong Doan reservoir in Tu Tra commune.

Roads in the Cong Doan reservoir area:

The main road from the district road DH413 to the dam is 472.94m. Other roads are 4,093.54m long. The roadbed is about 5.0 m wide. The road surfaces are 3.5m wide. Cross slopes are about 2%. Sidewalks are not reinforced as 2x0.75m made of soil. their cross slopes are about 4%. The road surface consists of a 5cm thick sand layer. Its M250 concrete surface layer is 18cm thick. Sidewalks is a soil-compressed layer K95.

Roads in the Tan Hien reservoir area:

The main road from the district road DH 412 to the dam is 1,268.36 m. Other roads are 3,474.3m long. The roadbed is about 5.0m wide. The road surfaces are 3.5m wide. Cross slopes are about 2%. Sidewalks are not reinforced as 2x0.75m made of soil. their cross slopes are about 4%. The road surface consists of a 5cm thick sand layer. Its M250 concrete surface layer is 18cm thick. Sidewalks is a soil-compressed layer K95.

Quantity and size of drainage culverts

- Road around Cong Doan reservoir in Tu Tra commune: 04 new culverts to be installed, including (i) 01 culvert D100 at the milestone C48 of the 3rd branch of route 2 length 8m; (ii) 01 culverts D100 at the mile stone C52A of the 3rd branch of route 2 length 8m; (iii) 03 box culvert D60x80 between the milestones C15 and C27 of branch 1st of route 1 length 8m and at the milestone C22 of the 2nd branch of route 1;

- Road around Tan Hien reservoir in Lac Xuan commune: 02 new culverts to be installed, including (i) 01 culvert D80 at the milestone C0 of branch 1 length 8m; (ii) 02 culvert D60x80 between the milestone TD9 of branch 1 and TD4 of branch 2.

Quantity of bridges There is neither existing nor being built bridge.

Irrigation and drainage system

Irrigation system:

- Tan Hien reservoir was built in 2005 to provide irrigation water

for about 8 ha 2-crop paddy and 4ha of vegetables. Due to the

reservoir was newly built, most of its items are still operational.

Its irrigation system consists of reservoir, spillway, control



Page 8


structures, culverts, inlets and pumps installed by local people.

- Cong Doan reservoir was manually dammed by local people since 1978. At the reservoir, people use pumps to directly take water. Over the long-term use without regular maintenance, it cannot store water by now.

- Subproject outputs (irrigation components of both reservoirs): repairing and upgrading works such as reservoirs, dam, spillway, intake gate, control valve, etc and build new canal in Tan Hien reservoir. It is estimated that the Tan Hien reservoir will provide adequate irrigation water for around 78ha of 3-crop vegetables and 30ha of 2-crop vegetables. Cong Doan reservoir will supply sufficient irrigation for about 49ha of 3-crop vegetables.

Drainage system:

- Only Tan Hien reservoir has an open drainage system but it has not been maintained regularly while it’s been obstructed due to cattle’s visiting.

The project will build culverts, flooding spillways to discharge water from both reservoirs. Water is discharged through the drainage system in the two sides of the dams and along roads connected with the reservoirs. The drainages are made of stone, reinforced concrete with reinforced concrete plates at intersections with the existing soil roads to ensure stable drainage systems. The culverts also have drainage function. The road-cross drainage system is the pipes with diameters of D80mm and D100mm.

Site clearance1

According to the land acquisition completion report of this subproject, the SP will affect 32 APs in total, in which 08 APs will be permanently acquired 620 m2 of agricultural land (for constructing downstream irrigation canal of Tan Hien reservoir) and 24 APs will be temporarily acquired 1,770 m2 agricultural land (for installing pipeline). The acquired land area will be rather small when it only accounts for 0.8% - 2.5% of their total land. The acquired land is located at the border of household’s land to minimize the affected asset. Neither structure, nor plant is affected.

Traffic roads that intersect with subproject’s roads

Currently, the roads in the sub-project area mostly are soil roads so it is very polluted by dust in the dry season and muddy in the rainy season.

The subproject road in Lac Xuan commune connects with National Highway No. 27, No. 20 and district road DH 412. The subproject area is about 3.5km from the national highway 27 to the southeast, 15km from the national highway 20 to the southeast and the DT 412 is 1,42km to the south.

The subproject road in Tu Tra commune connects with National Highway No. 27, National Highway No. 20, district road DH. 413, inter-communal roads and inter-village roads. The subproject is 5.84km to the highway 27 in the east, 8.33km to Highway 20 in the Southeast

1 According to Land Acquisition Completion Report (January 2016) and SIR (2015)

The main river/ streams/ reservoir in the subproject area.

The subproject area has some small basins as the ones of rivers in upstream with low terrain to create reservoirs. River/stream morphology is indistinct. streams only appear in the rainy season.

• River:

Da Nhim river runs along the south of highway 27. It originates from the northern of the district to the south then flows into Da Dang river. This is the district's largest river where water is abundant throughout the year and mainly supplies water to crops.

- Lac Xuan commune is 3.62km far away from Da Nhim river to the eastward.

- Tu Tra commune is 3.05km far away from Da Nhim river to the southward.

• Reservoir:

Beside 02 upgraded reservoirs of the subproject that are Tan Hien reservoir in Lac Xuan commune and Cong Doan reservoir in Tu Tra commune, there are also Da Nhim hydropower reservoir in the east and Proh, Da Ron, Proh, Ka Zam, Rlom, Ka Bang, Ma Danh reservoirs.

• Stream:

Along Da Nhim river and surrounding Tan Hien and Cong Doan reservoirs there are many unnamed small creeks/ streams

Number of hills and mountains

- Areas in the east of Lac Xuan and Tu Tra are characterized by hilly and mountainous terrain. The areas have potentials to develop agriculture and surrounded by high mountains, along the national road 27 and inter-commune roads, communes' main road, therefore agricultural activities also have advantages. The terrain in the areas also creates favorable locations to construct reservoirs and small irrigation works and Tan Hien and Cong Doan reservoirs are surrounded by hills

III. CONSTRUCTION ACTIVITIES

Commencement (month/year)

Planned: Quarter IV of 2016

Finish (month/year)

Planned: Quarter IV of 2018 (24 months)

Number of construction worker

Estimated around 150 workers

Camps for workers Yes, there will be 03 camps (02 main camps on the left side of Cong Doan reservoir and 01 sub-camp on the right side of Tan Hien reservoir)

Construction in the rainy season

In rainy season, there could be some activities such as: Completing the spillway, dam embankment, mechanical and electrical system, grass planting, etc. The main construction activities will be implemented in the dry season

Number of concrete mixers

The sub-project will employ 08 mobile concrete mixers with a capacity of 250-500l each.



Page 10


Construction methods

Upgrading the reservoirs

Flow diversion when upgrading the reservoirs: Two reservoirs that will be upgraded, repaired have relatively small basins. In the dry season, their discharge are only 2-3l/s, so the flow diversion for construction is negligible.

- Tan Hien reservoir: Flow will be diverted through the old culverts under the dam;

- Cong Doan reservoir: Before constructing spillway, flow will be diverted through the old pipe. After completing the spillway, flow will be diverted in to the spillway to construct other components.

Constructing the irrigation component

- Soil dam: The construction is mainly done by machines and combined with hand;

- Spillway: After removing a soft soil layer on surface, use excavators and trucks to transport soil to embank the dam downstream.

- Water intake: The construction is mainly done by machines and combined with manual;

Dredging the reservoirs: In the dry season, the reservoir beds are almost dry. So, it just needs to dig and divert flow from upstream through the old culverts under the dam to collect water and make the bed dry. Embanking the construction roads by soil taken at the reservoir bed. Dredge the reservoir bed to the designed elevation. When dredging to the reservoir shore, pay attention side slope coefficient. It must meet a minimum standard and avoid too steep to make easy landslide.

Constructing traffic road component:

The construction is mainly by machine to ensure the quality, but the construction should be combined with manual labor. Each road, it can arrange two construction groups. One from the beginning to the middle-road. Another is from the middle point to the end point. It is best if the construction is applied the section separate method that will not occupy much road surface and not cause traffic jams.

Material sources and disposal area.

Source of materials:

- Soil: use of dredged soil from Tan Hien and Cong Doan reservoirs to fill an embankment (see Annex 3 the agreement on borrow pit).

- Freestone, crushed stone and sand will be bought in Don Duong and surrounding area of the subproject within 15-20km far away.

- Cement, steel, formwork will be bought from Thanh My town.

- Asphalt will be purchased from Da Lat City;

- Electric Power: From the national grid. Besides, 03 standby generators will be also mobilized.

Disposal area:

PPMU Lam Dong arranged 10 disposal areas located differently to



Page 11


dispose construction wastes and dredged materials, including 5 locations on local people’s land and 5 managed by Lac Xuan and Tu Tra CPCs. All these disposal areas were accepted by the local people or authorities. The size of each disposal area is as bellow:

� The maximum speed is 28 m/s;

Natural Disasters:

Main natural hazards in the Central Highlands and in Lam Dong province consist of (i) drought in the dry season and (ii) flood in the rainy season. (iii) There are also other risks that happened in history, such as landslides, cyclones, hail, heavy rain, hot and stuffy.

- Storms in 1994, 1999, 2000.

- Extreme heavy rains with high rainfall caused landslides to the mountainous area (for example, landslides occurred in Don Duong district in 2010 after a heavy rain).

- Drought: A prolonged drought in 2002 left negative impacts on Bao Loc, Bao Lam, Da Huoai, Da Teh, Cat Tien and a drought in a large extent in 2015 affected 217 reservoirs in Lam Dong province badly (including Cong Doan and Tan Hien reservoirs), causing water shortages for irrigation (Source: Hydrometeorology Center of Lam Dong)

Topography and soil

Per the subproject Investment report (SIR):

- The subproject area is dominated by plateaus and mountains. Beside mountainous area, the plain area locates along the main roads of the center of Lac Xuan and Tu Tra communes.

- Geology of subproject area includes: (i) the outermost layer is yellow,



Page 20


dark brown humus containing plant remnants with 0.4m thick; (ii) the second layer is gray black, dark brown clay containing sand and grit; (iii) and the third layer is dark yellow, blue gray clay containing macadam, weathered grit and sand.

Surface water resource

- The main surface water resource in the subproject area is from Da Nhim river originating from the northern of Don Duong district and flows to the southern into Da Dang river. This is the district's largest river with abundant water throughout the year and it is the major irrigation water for the crops.

- The subproject area has some small basins that are actually upstream valley rivers with low and hollow terrain developed as reservoirs with unclear shape of a river/ stream. Streams only flow in the rainy season. Reservoirs nearby the subproject are as table below:

Reservoir Location Area (km2)

V. ENVIRONMENTAL IMPACT SCREENING

5.1 Positive impacts

Implementing the subproject "Repairing, upgrading productive rural infrastructure in Lac Xuan and Tu Tra communes, Don Duong district, Lam Dong province” will bring positive impacts on environment and society as follows:

- Increase water surface and stabilization of reservoirs will create positive impacts on local climate, especially increasing humidity in dry season of the subproject area;

- It will ensure water to irrigate initiatively for 127 ha of 3-crop vegetables, 30 ha of 2-crop vegetables, especially in the dry season. Thus, the subproject will improve agricultural productivity as well as income of local people;

- It will also contribute to stabilizing groundwater resources around reservoirs; - The traffic from residential areas to production areas will be improved, hence

transportation of materials and fertilizers as well as agricultural products will be more convenient. In addition, improvement in transportation creates favorable conditions for mechanizing agricultural production, bringing scientific advances into production, intensive cultivation to increase crop yields. The sub-project also reduces cultivation and labor costs and improves income of local peoples in the subproject area.

- It contributes to early completion of criterion No.2 - on transport, criterion No.3 - on irrigation, criterion No.10 - on incomes, criterion No.11 - on poverty rate of the new rural criterion in construction plan of new rural areas, which have been approved and are deployed at the locality.

- The sub-project will also contribute to improving living conditions, livelihoods and environment in sub-project areas and contribute to reducing poverty.

5.2 Negative impacts

household will be from 30m2 to 200m2. The acquired land is agricultural land located at the border between two households and it does not create the income. Neither structure nor tree on the acquired land will be affected. All APs were consulted and they agreed to donate their land for the subproject. (Source: land acquisition completion report of the subproject)

Permanent land acquisition: constructing downstream irrigation canal of Tan Hien reservoirs will submerge 620 m2 of land. This area is agricultural land, belonging to 08 households in Lac Xuan commune and share about 0.8 – 2% of their total holding land, the acquired land is mostly fence, which will not cause any impacts on cultivation activities of these household.

Temporary land acquisition: Temporary land acquisition of the sub-project is 1770 m2 for installing pipeline in Tan Hien reservoir This area is agricultural land, belonging to 24 households in Lac Xuan commune and occupy about 0.8 – 2.5% of their total holding land. The household have voluntarily agreed to donate their land for sub-project, the temporarily acquired land will be returned to its original status after construction.

Affected object(s): 32 HHs in commune of Lac Xuan, Don Duong district.

Affected level: Social impact due to land acquisition is minor due to i) acquired land area is fence; ii) not create any impacts on cultivation of these household; iii) those household agreed to donated their land and vi) many local HHs will get long-term benefits from the sub-project.

Affected Location: (i) Agricultural lands of 32 HHs in Tan Hien reservoir areas (Don Duong district).

No

No

Description: The sub-project will raise normal water level +0.52 m at Tan Hien reservoirs and Cong Doan reservoir by 0.67m. This design allows increasing water storage capacity of these reservoirs. The raising of water level in reservoirs could be cause impact of losing land around reservoirs at the time of full water storage. However, according to “Technical Design”, raising normal water level and increasing water storage capacity could only increase design flood level in Tan Hien reservoir 0.24 m and Cong Doan reservoir from not functioning to lever 1,019.17 ASL; and will not affect agricultural land of local people and forest land.

Affected object(s): There is no impact on forest land due to improving the water level of reservoirs, only small shrubs of no value are growing in the stretches and agricultural perennial plants that will be cleared for main canal and pipeline occupation in Tan Hien reservoir.

Affected level: Currently there is no impact, but if any impact occurs, it would be minor; This activity of sub-project will not affect any forest or vegetation around reservoirs.

Location: At 2 reservoirs of Tan Hien and Cong Doan;

Time: This impact is permanent, if any.

Yes

Moderate

Negative

Temporary

Description: The construction period will be 24 months; it can potentially cause negative impacts on crops of local people if the construction is taking place contemporarily with cropping activities. The construction activities on reservoirs could lead to shortage of water for irrigating if withdraw water plans on reservoirs are not consider to cultivation schedules of local people. The shortage of irrigation water could cause reduce crop productive or even cultivation activities could be not implemented. This could result in negative impacts on the socio-economic situation of local people. The construction of reservoirs and works as well as dredging reservoirs must be mainly implemented in the dry season– the same period of agricultural

activities. Therefore, this potential impact needs to be managed and mitigated carefully. At this moment, only Tan Hien reservoir can store water and supply irrigation water for around 8ha of 2-crop paddy and 4ha of vegetables. Cong Doan has not store water because its dam is not capable of storing water.

Construction activity lasting 24 months may be inappropriate to the agricultural production of farmers in term of time. It may reduce crop yields around Tan Hien reservoir. Thus, if the construction plan is inappropriate, it can lower the productivity of 8ha of paddy and 4ha of vegetables which are irrigated from Tan Hien reservoir.

Affected object(s):

- Crops irrigated from Tan Hien reservoir;

- Local peoples in Lac Xuan commune

Affected level: The negative impact described is considered moderate due to i) flow diversion construction method will be applied to ensure sufficient water irrigation for cultivation activities; ii) works will be implemented section by section which could help to reduce interruption period.

Location: Productive areas of 8ha of wet rice and 4ha of vegetables which are irrigated by Tan Hien reservoir, Lac Xuan commune.

Time: Temporary, during construction phase (24 months).

II. Construction phase

Description: Construction activities, especially excavating, filling/embankment works and storing materials in Tan Hien, Cong Doan reservoir and new canal in Tan Hien reservoir such as roads could create debris and/or cause materials falling into water sources. Landslide may be occurred at the slope of 2 borrow pits areas in bed of Cong Doan and Tan Hien since they are located on high slope areas. The soil erosion and landslide could cause increasing in sediments and turbidity in surface water as well as

obstructing water flows. The consequence could cause negative impacts to the rice fields in Lac Xuan and Tu Tra communes where are located near by the construction sites. The highest risks location of land slide and soil erosion could be listed as below:

- Soil erosion caused by the excavation and dredge of Cong Doan, Tan Hien reservoir beds and constructing new canal, upgraded roads

- Erosion of banks of pipeline and aqueduct built to cross over these streams;

- Landslide at 2 borrow pit areas in Cong Doan and Tan Hien reservoirs

Affected object(s): (i) Water surface sources & streams at Tan Hien and Cong Doan reservoir; (ii) Crops being irrigated by 02 upgraded reservoirs; (iii) Slopes of reservoirs, canal in Tan Hien reservoir and roads;

Affected level: Minor, because i) the material sources are mainly taken from excavation and dredge of Cong Doan, Tan Hien reservoir beds; ii) the volume of excavation/ embankment are relatively small and scattered along roads & reservoirs in Lac Xuan and Tu Tra communes, (iii) excavation will be mainly taken during dry season. However, this impact still needs to be properly managed and controlled to reduce surface water pollution

Location: slope of the upgraded roads, new canal and Tan Hien, Cong Doan reservoirs.

Time: Temporary during the construction phase.

- Surface water of Cong Doan and Tan Hien reservoirs;

- Small streams in Tu Tra and Lac Xuan communes.

Affected level: Because of the importance of surface water, thus this impact is moderate , due to i) the construction activities will be scattered in the larger areas in Tu Tra and Lac Xuan communes such as 02 reservoirs, irrigation canal of Tan Hien reservoir, upgraded road and 03 camps (02 main camps on the left side of Cong Doan reservoir and 01 sub-camp on the right side of Tan Hien reservoir) with small workers will be mobilised on the site (estimated 150 at maximum); ii) as scheduled, excavation activities will be taken place in dry season, and about 70% of excavated soil/ dredged materials will be utilized for embankment, therefore impacts of runoff water will be reduced and iii) generations of domestic waste-water (about 15 m3/day), grease and engines’ oil are limited; iv) water in reservoirs will be withdraw before excavation. But appropriate mitigations need to be implemented and monitored to minimized impacts and appropriate mitigation measures must be applied.

Location: Cong Doan and Tan Hien reservoirs; small streams and canals along the upgraded works in Tu Tra and Lac Xuan communes.

- Resident areas closed to reservoirs of Cong Doan, Tan Hien; canal of Tan Hien reservoir and roads in Lac Xuan, Tu Tra communes

- Resident areas along the material and waste transportation roads to works.

- Resident areas closed to borrow pits and disposal sites

Affected level: This impact is minor due to: i) very few equipment will be mobilized on the site; ii) borrow pits and disposal sites are located in reservoirs bank or vacant land and no households located close to disposal areas/borrow pits; iii) density of households around construction sites is low; iv) The noise will reduce sharply by the distance, especially where trees are plentiful as of the subproject area.

Location: Residential areas near construction site in Tan Hien and Cong Doan reservoirs and along transportation roads in Lac Xuan, Tu Tra communes.


Air pollution Yes Minor Negative Temporary

Description: Dust and other air pollutants will be generated from excavation activities, waste disposal activities, electrical generators, mobile concrete mixers or operation of vehicles/ construction machinery such as truck, concrete mixer, bulldozer, excavator, generator, etc, material storage areas. 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, borrow pits. Therefore, the main issue is dust which will be released from excavated surface (since excavation activities will be implemented during dry season) and generated from operation of trucks which need to appropriate manage to reduce impacts on local people.

Description: Constructing headworks, canal and road of the subproject may block water flows and cause flooding to the locality, especially in the rainy season. Water intake in reservoir of Cong Doan, pipeline in Tan Hien reservoir, new drainage culverts on roads around Cong Doan, Tan Hien reservoirs will be constructed, design may be inappropriate or contractor will not fully follow the technical specifications which could lead to inadequate discharged aperture of these works or flow obstruction. Moreover, existing spillway, intake gate in 2 reservoirs could also be blocked due to equipment and material and construction waste placed on these intakes. Temporary bock of drainage culverts and intakes may cause temporary and locally flooding, if it will be happened for long period which may cause damage on crops, access roads in the surrounding areas and create many insanitation issue and disease release.

Affected object(s):

irrigation/drainage canals of Tan Hien and Cong Doan reservoirs.

- Local people in the beneficiary area

Affected level: It is minor impact due to i) flow diverted method will be applied to ensure water flow in the existing works during construction phase; ii) excavation activities will be planned to implement during dry period, works will be repaired/ upgraded at the same schedule, road upgrading will be performed in the last months of the year, except on rainy days; iii) intervention will be conducted section by section and iv) very small adjustment will be implemented in the existing drainage system and almost functions will be remained that ensure its functions during construction phase; v) design of upgrading reservoir systems will be contributed in drainage function of watershed; and vi) finally, the subproject area has not recorded any tremendous flood.

Location: Upgraded reservoirs, roads and other works of Tan Hien and Cong Doan reservoirs in Lac Xuan, Tu Tra communes and cultivation areas along the works.

Time: Temporary during the construction phase, but it will be long-term with inappropriate design.

Description: The upgraded road of the subproject will be constructed on the existing road. Therefore, the construction will temporarily occupy the road. The operation of vehicles/ construction machinery in the narrow space of the upgraded road may cause (i) traffic accidents, especially involving the elderly, children and loose cattle and (ii) difficulties in transporting goods.

However, the upgraded road connecting to residential area and reservoirs (road connecting from district road DH 413 to the dam of Cong Doan reservoir and the road connecting district road DH412 to the dam of Tan Hien reservoir) is low traffic density. The road will be constructed section by section to reduce impact extent. Along the road there are lot of vacant and plain area which can

The left side of Tan Hien reservoir dam (garden and structure of village culture house), left side of Cong Doan dam (garden and house of teacher dormitory) near the road will be used to construct worker camps, material yards, etc. One sub-warehouse will be built at the dam upstream and near the culvert to store materials for constructing culvert and to gather vehicles/ construction machinery for embanking the dam. A sub-camp and a yard will also be built on the right side of downstream dam to construct right shoulder of the dam. However, the construction of culverts across the traffic road surrounding Tan Hien and Cong Doan reservoirs will temporarily divide the road and obstruct traffic. Local people must be noticed foreseen impacts during constructing the road to seek their understanding and cooperation. A detour must be developed when constructing the headwork to prevent traffic jam.

Affected object (s): Local people in the sub-project area and people traveling through upgraded roads, dam crests during construction phase.

Affected level: This impact is considered as moderate due to: i) upgrading of road and constructing new canal will be to occupied exiting road surface which may cause temporary block of access routes; ii) routes from construction sites to borrow pits and disposal areas is very narrow and low quality; iii) the road construction method is completing section by section with warning signs and informed schedule for local residents; iv) the traffic density on those roads are quite small. However, adequate traffic management need to be implemented to ensure traffic movement and safety for local people.

Impacts on ecology

Yes

Minor

Negative

Temporary

Description: No natural reserves, national parks, areas of important ecological value are recorded in subproject area. Therefore, it does not significantly affect the ecology. The areas of the 2 borrow pits at Cong Doan, Tan Hien reservoirs bank as well as 10 disposal site in Lac Xuan, Tu Tra communes are vacant lands in which only small shrubs of no commercial or scientific value are growing. Therefore, the exploitation of soil from such borrow pits will not have any noticeable negative impact on those lands or on the nearby plantations.

But the construction such as new canal and pipeline in Tan Hien reservoirW will impact on ecology at the upstream/ downstream dam, reservoir bed of Tan Hien and Cong Doan reservoirs and the upgraded road. However, vegetation cover at these places are shrubs growing naturally without economic value.

Affected object(s):

- Flora in the construction area at Tan Hien and Cong Doan reservoirs, 2 borrow pits at Cong Doan, Tan Hien reservoirs bank, 10 disposal areas, upgraded roads and new irrigation canal;

- Aquatic flora & fauna in 2 upgraded reservoirs of Tan Hien and Cong Doan.

Affected level: Minor impact. According to site observation in 04/2015 the areas along upgraded road and around reservoirs of Cong Doan and Tan Hien, disposal sites and borrow pits are covered with grass or vacant lands and sub-project do not acquire those lands. While the aqua species almost small fresh fish in reservoirs without or less economic value as well as reserved. Furthermore, the impact is temporary as specific constructed places and ecological environments will recover soon after completion of construction;

Yes

Moderate

Negative

Temporary

Description: Solid wastes generated during the construction phase include:

i) Non-toxic waste included: (i) construction wastes (abundant & discarded soil, sand, stone, debris, steel, etc.) are estimated around 238,393.3m3 of abundant soil; (ii) domestic waste from 3 camps around 45kg/ day or 32 ton/ 24 months. This waste must also be collected and treated so that it cannot potentially pollute air, soil, surface water and environmental sanitation.

ii) Hazardous waste: Grease, lubricant, chemicals mops/duster cloth, fuel and chemical’s containers. Due to the extent of the subproject is small then vehicles/ construction machinery, and hazardous materials/ waste are less. However, if these hazardous wastes are not collected and treated appropriately, they may impact negatively on soil and water.

Affected object(s):

- Air quality in and around 3 worker camps and 2 borrow pits;

- Water quality of surface water bodies nearby camps and local productive fields nearby construction sites;

- Soil at and around 10 disposal areas;

- Workers living in the camps;

- Local people around the construction sites; camps and disposal areas and roads users on the transport route.

Affected level: This impact should be moderate due to: i) waste will be generated for whole construction phase; ii) worker camps will be separated in three difference (only 150 people in three camps; ii) larger volume of excavated soil will be utilized; iii) locations disposal areas are far from residential areas ( about 2km); iv) demand of hazardous material used on the site also very limited.

Impact/ damage on infrastructures

Yes

Moderate

Negative

Temporary

Description: According to field surveys in 4/2015, the inter-commune roads include both concrete (intersection connecting with the National Highway no. 27) and earthen roads. Most of these roads are degraded and damaged. The subgrade of roads connecting to Tan Hien and Cong Doan reservoirs is 3.0 – 6.0 m wide. Along the road has no water supply network, drainage pipe while the electrical lines are rather far from the roads. Thus, public infrastructure could be impacted is rural roads which will be used for transport material and wastes. The inter-commune road system is around 55km long with the allowable load is about 10 tons/ axis. The inter-village around is around 79km long with the allowable load is 5 tons/axis. Besides, there are a lot of small bridges. Therefore, the roads/ bridges of the subproject are likely damaged if vehicles with heavy load transport. PPMU Lam Dong need to specify in the bidding document that contractor is bound to repair or compensate for any damages to public infrastructures that they may cause.

Affected object(s):

- Road infrastructure utilized for sub-project construction;

- Local people in the sub-project area in Lac Xuan and Tu Tra communes;

- Passengers along roads used for sub-project’s construction.

Affected level: Moderate impact, due to the extent of transportation that needs for sub-project is small and scattered in commune of Lac Xuan and Tu Tra. In addition, there is no infrastructure for water supply system and/or drainage system are found in the subproject area, therefore these functions will not be impacted. Moreover, construction contractor needs to well prepare construction and transportation plan to minimize possible negative impacts and they are also bound to

Location: All roads/ bridges used by the sub-project in Lac Xuan, Tu Tra communes.


Social disturbance by worker gathering

Yes

Minor

Positive &

Negative

Temporary

Description: A lot of workers gather at the subproject site may cause both negative and positive impacts. (a) Positive impact: (i) Local people can sell goods for workers; (ii) local people can be recruited by construction contractors, hence their income will increase; (iii) increasing opportunity of cultural exchange of indigenous community; (b) Negative impacts: i) diseases such as sore eyes, cholera, flu and other respiratory diseases from workers may spread out local people in the subproject area; ii) social problems can appear such as gambling, drug addiction, prostitution, violence, conflict amongst workers, or among workers and local people. There is also a risk of sexually transmitted diseases (STD) from workers, including HIV/AIDS that need to be considered. All workers must be registered temporarily residence to minimize social problems.

Affected object(s):

- Workers on the sites

- People in Lac Xuan and Tu Tra communes;

- Business in Lac Xuan and Tu Tra communes;

Affected level: Both positive and negative impacts are minor due to i) the workers will be split in 03 camps in communes of Lac Xuan and Tu Tra; ii) local workers will be encouraged to mobilize on the site ( about 150 works; iii) construction schedule is just only 24 months and iv) finally, workers need to be managed and controlled to eliminate negative impacts;.

Negative

Temporary

Description: Dust and noise generated by construction activities and unsanitary living conditions will directly affect health of the workers and the local communities, especially in case of safety regulations are not properly complied with. Diseases can be gotten include insomnia, diseases related to eye, skin, heart etc. The high risks of health problem and safety for workers may also come from unsafe living conditions, unsafe food and water supply and inappropriate personal protection equipment and conflict between workers and road vehicles, traffic accidents involving people passing through construction places. Moreover, the construction activities may need to occupy road surface or add several vehicles on the rural narrow roads which could lead to unsafety for local people who use the roads. The construction of road around Tan Hien and Cong Doan reservoirs may also cause temporary bock access road of local people.

Affected object(s):

- Workers at construction sites;

- Residential areas along the transport route of materials in Lac Xuan, Tu Tra communes and near construction areas;

- Residential areas located along the upgrading road of Tan Hien and Cong Doan reservoirs

Affected level: This impact is minor, due to i) the number of construction workers (150 at maximum) as well as the volume of machinery and equipment used is small and mobilized to construction sites; ii) upgrading of Tan Hien and Cong Doan reservoirs roads will need to occupy the existing road surface; iii) there will be also temporary encroached the canal reservoirs to storage of material; iv) contractors will need to use narrow road for transport waste and material; v) workers are required to follow environment and labor safety measures.

However, road and works upgrading/ constructing will be constructed section by

section which will help to reduce intervention on existing ones. The number of equipment will be very limited. Larger volume of excavated soil will be reused which could help to reduce demand of transport. However, the importance of preserving human health and lives, including local resident and workers, adequate management measures need to be implemented and supervised.

Location: Construction sites of the subproject, communes along the roads through which materials/ wastes of the subproject will be transported and 03 camps.


Impacts from operation of quarries of soil, stone and sand


Description: According to the subproject investment report, excavated soil is more than filled volume in each component. The soil for embankment construction will be only 66,323m3, accounting for 21% of the excavated soil. Moreover, the soil will be taken from borrow pits at Tan Hien and Cong Doan reservoir banks, nearby construction sites. These areas are vacant land, managed by authorities via environmental in Lac Xuan, Tu Tra communes. Thus, the excavated soil will be utilized for embankment and only abundant soil will be disposed. Sand will be bought from the licensed sand mine in Don Duong district 15km from the site. Crushed stone will be bought from the licensed stone mine in N’Thon Ha commune, Duc Trong district 20km from the site. During the clearance and excavation period, the people who live near these mines could be disturbed by transportation activities, dust as well as redundant soil on the roads. However, the negative impact is minor because soil will be mined at the reservoir bed where soil is humid, less dust while sand and stoned will be transported from licensed mines where mitigation measures are applied

Affected object(s):

- Residents along transportation routes;

- Residents and workers mining/ dredging soil from Cong Doan and Tan Hien reservoirs’ bed.

Impact on existing irrigation systems

Yes Moderate Negative Temporary

Description: The irrigation constructions will take place at the existing dam, reservoir bed of Tan Hien and Cong Doan reservoirs The Tan Hien reservoir is currently providing water for about 29 ha, and Cong Doan reservoir is 12 ha, mainly rice and vegetables. The upgrading the reservoirs and works will temporarily affect their irrigation functions. Upgrading 2 reservoirs of Tan Hien and Cong Doan needs to divert flow and done in the dry season, when there is high water demand. So, the upgrading might affect undesirable for crops if the impact mitigation measures are not implemented properly.

Although the total construction period is rather long (2 years), reservoirs and canals will not be constructed at the same time. Therefore, the impact is just moderate.

Affected object(s):

- 41 ha of crops irrigated by reservoirs of Cong Doan, Tan Hien;

- Beneficiaries in Tu Tra and Lac Xuan communes.

Affected level: This impact is moderate due to i) their main impact is only in the dry season; ii) the construction will be implemented in subsequent sections with diversion flow methods to ensure irrigation water supply for cultivation activities; iii) works will not constructed at the same time; iv) the

Temporary and Permanent

Description: The construction contractor needs to restore damaged environment and public structures to its original status. If environmental recovery activities will not be properly implemented, natural environment of the subproject area may suffer from: (i) loss of trees along upgrading roads and loss of vegetation on the new constructed canal and pipeline areas; (ii) loss of some aquatic flora & fauna species during upgrading Tan Hien and Cong Doan reservoirs because of water withdrawal; (iii) changing environmental landscape at 10 disposal areas; and (iv) downgrade of existing public infrastructures. Moreover, restoring the original environmental conditions of damaged features may also have some positive impacts. These may include strengthening road surface, which could result in their longer use and become better in terms of safety for local people as well as increasing green space in recovered areas.

However, the aquatic species could easily be re-grown from the same species largely available in upstream; trees to be cut down are not rare and/or of rare species needing

Impact on water quality due to increase of fertilizer or pesticide volume

Yes Minor Negative Permanent

Description: Upgrading irrigation canal system will boost productivity. Thus, the use of fertilizers and pesticides will increase; demand of irrigation water will also increase; this will affect both surface and ground water in sub-project area. If fertilizer/pesticide bags are not collected, it may affect badly aquatic ecology and people health.

Affected object(s):

- Surface water of reservoirs and canals in the subproject area.

- Water resources surrounding the productive areas irrigated from the irrigation system of the subproject.

Affected level: Impact predicted is minor because an increase of fertilizers and pesticides is relatively low; moreover, it is also expected that the increasing trend of using environmental-friendly products will prevail in the coming future.

- Flow diversion methods will be applied during upgrading of Cong Doan and Tan Hien reservoirs to ensure water availability for irrigation (Winter – Spring crop from December to April; Summer-Autumn crop from May to August) during construction phase.

+ Upgrading the reservoirs

Flow diversion when ugrading the two reservoirs: The two reservoirs to be upgraded have relatively small flow. In the dry season, the flow is about 2-3l/s. Therefore, the flow diversion is negligible

� Tan Hien reservoir: Flow will be diverted through the old culverts � Cong Doan reservoir: Before

contructing spillway, flow will be diverted through the old pipe. After completing the spillway, flow will be diverted through the spillway to contruct other components.

+ Dredging the reservoir beds

� Tan Hien reservoir: It will dredge the reservoir bed to the designed altitude equal 1,013m, while dredging nearly the reservoir banks, it must pay attention the minimum roof coefficient m=1.5;

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 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.

- Lam Dong PPMU and CSCs: 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 person 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 his/her complaint is not resolved, the complainant may submit an application to the Don Duong DPC to resolve the complaint.

Stage 3: If more than 15 days passed without response from Don Duong DPC, the complainant may submit a complaint to the Lam Dong PPC (through Lam Dong DONRE). Lam Dong PPC will require Don Duong 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:

X. CONCLUSION, COMMITMENT AND RECOMMENDATION

10.1 Conclusion

The results of environmental screening and environmental impact assessment show that the sub-project may cause some adverse environmental impacts, but that most of these impacts are site specific. The appropriate mitigation measures in EMP are proposed to manage the negative impacts and maximize the benefit of the subproject. The responsibilities of implementation and monitoring of the stakeholders have also been identified to ensure environmental compliance.

10.2 Commitment

Lam Dong PPMU of the sub-project “Repairing, upgrading productive rural infrastructure in Lac Xuan and Tu Tra communes, Don Duong district, Lam Dong province” commits to:

- Implement requirements of environmental safety as stated in IEE via information dissemination, integrating environmental requirements as stated in this IEE into bidding documents, construction contracts with contractors and the construction supervisor contracts with construction supervision consultants; mobilize human resources and monitor internally the IEE compliance;

- Report environmental safety implementation to DONRE and CPMU periodically as specified in the IEE;

- Compensate and take measures against environmental pollution if there are any problem during operation of the sub-project;

- Handle complaints if any.

10.3 Recommendations

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

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

- Based on IEE, PRI CHP of Lam Dong would like to request functional authorities to give their approval of the IEE for “Repairing, upgrading productive rural infrastructure in Lac Xuan and Tu Tra communes, Don Duong district, Lam Dong province” sub-project, to create the basis for next implementation steps, ensuring the implementation progress, effectiveness and benefits of the project.

Impacts on soil, stones and sand mines.

To minimize environmental impacts caused by mining raw materials for construction

- Embanked soil is exploited from beds of Tan Hien and Cong Doan reservoirs under Lam Dong Irrigation exploration and management company;

- Sand is purchased at Don Duong mine. Crushed stone is bought a licensed rock mine in Duc Trong district (40-50km). Environmental impacts from the exploitation were mitigated by the mine owner and monitored by competent agency of the locality.

- Materials will be transported continuously to construction sites.

- The materials are easy to evaporate and generate dusts, so it needs to cover carefully.

Areas around 2 borrow pits areas at the reservoirs’ bank of Cong Doan, Tan Hien, material mines, and areas along transportation roads

14

Impact on existing irrigation systems

Avoiding and minimizing situation of lacking water for irrigation

- Plan of construction the irrigation system must be considered to water availability for agriculture fields. Those plans need to be agreed with DARDs (Lam Dong and Don Duong) and Lac Xuan and Tu Tra communes and announced to local residents;

- Construction contractor needs to apply appropriate measures that ensure water enough for fields downstream.

- Construction need to be implemented in subsequent sections to minimize impacts

- Contractor must compensate for damages due to shortage of irrigation if this is from the construction;

Tan Hien and Cong Doan reservoirs, irrigation canal at downstream of Tan Hien reservoir.

15


Avoiding, minimizing impacts on surrounding agricultural activities

- The construction plans need to be reviewed and agreed among Lam Dong DARD, Don Duong district and communes (Lac Xuan, Tu Tra) and displayed on notice boards of such communes;

- For road component: Contractor may arrange two contruction group, One contructs from the beginning point to middle point of the route. Another is from the middle point to the end. Apply the mat rolling method, section by section to minimize traffic jams.

- The transportation network in sub-project area is quite good and convenient, thus

The areas surrounding Cong Doan, Tan Hien reservoirs and upgraded works as well as productive areas in Tu Tra and Lac Xuan communes



Page 34

during construction period, the traffic distribution method should be established and having traffic guides to local people who traveling on the routes nearby.

- For Cong Doan, Tan Hien reservoirs and headworks: construction plans need to be such that water supply to irrigated fields will not be discontinued.

Flow diversion when upgrading the reservoirs: Two reservoirs tol be upgraded, repaired have relatively small basins. In the dry season, their flow volumes are only 2-3l/s, so the flow diversion for construction is negligible. In Tan Hien reservoir, flow will be diverted through the old culverts under dam. For Cong Doan reservoir, before constructing spillway in combination with bottom discharged flow is diverted through the old culverts. After completing the construction, flow will be diverted through the spillway to construct other components.

- Any negative impact to irrigated fields (mainly insufficient or interrupted water supply causing losses to crops) occurring during construction period need to be adequately compensated;

16 Cultural objects or graves found

Avoiding and minimizing impacts on cultural objects or graves

- If any cultural objects and/or graves are found during construction phase, the construction activities at those places need to be temporarily stopped and immediately informed local authorities to deal with the issue;

- Appropriate assistances need to be implemented after consultation with households suffering from any impact on their graves, and the construction contractor should provide necessary support to these HHs to resettle graves elsewhere or to communes for cultural objects found;

All construction sites and borrow pits in Lac Xuan, Tu Tra communes.

17 Environmental recovery activities

To ensure damaged environment and related infrastructures will be recovered after completing construction

- During construction, any damage to local infrastructure will be repaired and recovered to its original condition or compensated by construction contractor if they cannot be recovered as mentioned above;

- The environmental issues emerged during recovery activities such as noise, dust, gases, solid waste, hazardous waste, water pollution etc. will be handled with similar measures indicated in related section above;

- Re-planting cuter plants/trees after completing construction activities;

- Repairing damaged infrastructures as soon as possible;
