1. BACKGROUND OF THE PROJECT

WSSP Project will improve public health and environment for about 400,000 people (households and

other consumers) living in 18 towns and up to 92 villages1 through safe, reliable and sustainable water

supply. The outcome of the Project is improved access to safe, reliable, and sustainable WSS services

managed on commercial principles and environmentally sound practices.

The Project will also support poverty reduction by (i) reducing the incidence of waterborne diseases and

costs of medical care; (ii) improving the time poverty of women due to labor intensive housework such as

water collection, which may allow them to participate more in social and economic activities; (iii) providing

safer and more reliable water supply; and (iv) improving the quality of life of households in all the project

towns and villages by improving their access to safe and sustainable drinking water.

Similar to the original WSSP, the Additional Financing Project will fund two project components which

include: (i) municipal infrastructure rehabilitation and improvement; and (ii) management improvement and

development which include gender features.

2. ENVIRONMENTAL AND SOCIAL SAFEGUARD DOCUMENTS

4. DESCRIPTION OF THE CURRENT WATER SUPPLY AND SANITATION

SYSTEMS.

Water supply of Echmiadzin town and Lernamerdz, Amberd, Aygeshat, Dasht, Doghs, Musaler, Shahumyan,

Shahumyan poultry, Norakert, Hushakert, Aghavnatun, Ptghunk, Voskevaz, Voskehat, and Oshakan rural

communities is implemented from the Bazmaghbyur and Ghazaravan undergroung sources through three

main systems:

Bazmaghbyur-Echmidzin gravity system

Ghazaravan-Echmiadzin gravity system

Ghazaravan-Echmiadzin gravity system (“Chaleri Djur”)

Currently there are 10 catchements and 2 chlorination stations in operation. Existing 14 deep wells are not

operated and used for supply of water to Echmiadzin town and villages.

Water from headworks is being transported by three main pipelines with diameters varying from 300 through

600mm with total length 136km.

In 2007-2011 water supply network of Echmiadzin town has been rehabilitated under the World Bank

funding.

7

In 2008-2012 rehabilitation of external feeding water supply systems of Echmiadzin town and rural

communities has been implemented in frame of Water Supply and Sanitation Project funded by the ADB.

Among the communities under consideration only Echmiadzin town has sewerage system, but the waste

water treatment plant is not functioning. There are broken sections within main collectors and inter-district

sewerage networks, some of the inspection chambers need repair.

Lernamerdz, Amberd, Aygeshat, Dasht, Doghs, Musaler, Shahumyan, Shahumyan Poultry Farm, Norakert,

Houshakert, Aghavnatun, Ptghunk, Voskevaz, Voskehat and Oshakan villages have no sewerage system,

people make use of eather outhouse toilets or indoor toilets connected to outdoor sewage collecting chambers.

In some of the villages individual buildings such as schools, kindergartens and others, have sewage systems.

5. GEOGRAPHICAL LOCATION AND CLIMATE OF THE SETTLEMENTS

From the communities covered by the subproject town of Echmiadzin and Lernamerdz, Amberd, Aygeshat,

Dasht, Doghs, Musaler, Shahumyan, Shahumyan Poultry Farm, Norakert, Houshakert, Aghavnatun, Ptghunk

villages administratively belong to Armavir marz, while Voskevaz, Voskehat and Oshakan villages belong

to Aragathotn marz. They comprise part of south-south west area of the country, where terrain has slight

inclination and envolves not high hill ranges. Altitudes vary between 950 and 1100m asl.

3.1 Echmiadzin town and Lernamerdz, Amberd, Aygeshat, Dasht, Doghs, Musaler, Shahumyan,

Shahumyan Poultry Farm, Norakert, Houshakert, Aghavnatun, Ptghunk rural communities of

Armavir marz

The area of Armavir marz under consideration located in the west of Ararat valley, on the left bank of Araks

river. The area of Armavir marz is the smallest and occupies 1200sq km. The marz capital town is Armavir.

Town of Echmiadzin located 25 km far from the marz capital, and 20 km far from Yerevan city.

The area is characterized by warm, hot summers and cold non-storm winters. Monthly average temperature in

July is 21,5oC and in January 3.8

oC. Air absolute maximum temperature is 41

oC, absolute minimum is -31

oC.

Average annual precipitations vary between 280 -340mm. Snow cover reaches 42cm. Soil freezing depth vary

between 0.5-0.7m, depending on altitude. Air average relative humidity equals to 59%. Wind annual average

speed is 1.8m/sec.

From the orography point of view one can distinguish two regions in Ararat’s ravine: one encompasses the

foothills zone, and the second one that includes the area under study is а wide valley filled with river and

flood sedimental formations (accumulation terraces and floodplain of Araks river ).

8

From hydro-geological point of view the area is rich with undeground waters. They can be found on the

different depths starting from 0-5 through 100 meters and deeper. Existance of the ground waters is

conditioned by river and lake formations and cracked andesitic basalts.

Populated area of the communities is located at the elevations limited by 800 and 1000 meters asl.

3.2 Voskevaz, Voskehat and Oshakan rural communitis of Aragatsotn marz

The area under consideration of Aragatsotn region is located in foothill zone of Ararat Ravine at a distatnce

of 3-5 km to south-west from Astharak towm and at distance of 20-22 km from Yerevan city. The regional

center is Ashtarak city.

The climate of the area under study in Aragatsotn marz is acutely continental characretized by hot summers

and rather cold winters. The average annual air temperature is +9.1 C, the аsolute minimal temperature is

down to -34 C and absolute maximum temperature is up to +38 C. Аverage annual precipitation rate is 447

mm, and the maximal precipitation rate is 715 mm. The average snow cover in winter is 28 cm and the

maximal one is 68 mm. The maximal soil freezing depth is 79 cm. The air relative humidity average for

several years is 62%. The annual average wind speed is 2.8 km/sec.

The terrain here is conditioned by specificities of the geological, climate, disposition and other factors. The

area of Kasakh river has widespread landscape rugged with foothill specific valleys. On the northern part the

area is contiguous with the southern lower slopes of Aragats mount, where volcanic elements of the Armenian

mountain range are present in geological formation.

Since volcanic formations are subject to intensive erosion and are badly fractured, the underground waters are

infiltrated rather deeply and located at the 15-20 m and deeper.

Populated areas of the communities is located at the elevations limited by 950 and 1100 meters asl.

7. ENVIRONMENTAL IMPACT

Initial Environmental Examination (IEE) has revealed that no damage is expected to be caused to the

landscape, flora, fauna, land and water resources of the area where works on improvement of the water supply

systems will be impelemnted.

The sub-project will be implemented mainly in the urban areas of the settlements, and new areas will not be

used for the purposes of the works implementation.

As to the preliminary environemntal inspection the sub-project was classified as B category project. Along

with the Detailed Design an Environemntal Management Plan has to be elaborated for this project, which

shall cover all the communities that are included in the Detailed Design.

volcanic eruptions and climate changes (see Appendix I)?

+ Armenia located in active tectonic zone with

all possible consequences

Could changes in temperature, precipitation, or extreme events

patterns over the Project lifespan affect technical or financial

sustainability (e.g., changes in rainfall patterns disrupt reliability of

water supply; sea level rise creates salinity intrusion into proposed

water supply source)?

+ Decline of precipitations may cause decrease

of water source discharge , which in its turn

will lead to disruption of sustainable water

supply

Are there any demographic or socio-economic aspects of the

Project area that are already vulnerable (e.g., high incidence of

marginalized populations, rural-urban migrants, illegal settlements,

ethnic minorities, women or children)?

+

Could the Project potentially increase the climate or disaster

vulnerability of the surrounding area (e.g., by using water from a

vulnerable source that is relied upon by many user groups, or

3. INTRODUCTION

The very report is developed for the Subproject on the Improvement of W&W Systems in Oshakan,

Voskevaz, Voskehat villages of Aragatsotn region, the design of which has been performed by the JV of

HGSN and JINJ LLCs. The Water supply systems rehabilitation involves activities on reconstruction

and repair of water distribution systems, as well as construction of new water pipelines, regulating and

water measuring junc.

As a result of the construction work implementation, as well as further operation and maintenance of the

water supply systems there might be undesirable negative impacts on the environment.


18

It is expected that the impacts during construction work implementation will be the least and temporary,

probably involving vegetation cut, soil erosion, air and water resource pollution by lubricants, household

and construction waste.

At the Operation Stage the environmental impact, the main reason of which might be improper execution

of operation requirements, will decrease.

The improvement activities will be considered environmentally friendly in case of water resource

conservation, as well as rational and steady use.

The social and economic effect as a result of water supply system improvement are expected to be long-

term, mostly positive, excluding potable and waste waters mix, minimization of water pollution risk,

prevention and exclusion of infection disease agents penetration into potable water, as well as water

supply extension, providing steady water supply and rational water use.

The EMP Part 5 introduces description of possible impacts and facilitating measures required during

different stages of Water Supply Systems Rehabilitation Project.

Designing stage

The design works on water systems have been performed by the JV of HGSN and JINJ, which has been

selected as a Consultant who provides services on civil works and public awareness campaign within the

framework of “Water Supply and Sanitation Sector Project – Additional Financing”. The EMP includes

articles on climatic conditions, relief, natural soil types, hydrology and biodiversity of the very package,

4. SCOPE OF WORKS

4.1. Description of existing water supply systems

The total length of water supply distribution network in Oshakan, Voskevaz, Voskehat rural communities

is about 50 km, which is fed through the ground springs of Ashtarak region.

19

The water supply of Oshakan community is mainly performed through DN300mm conduit running to the

village from 500 m3 DRR. A number of north-eastern areas are fed through DN250 mm water main

Kheres.

The water supply of Voskevaz community is performed through 150 mm diameter steel pipes fed

through 2x500 m3 DRRs.

Voskevaz water supply is mainly performed through 500 m3 DRR with pump station and 80m

3 capacity

reservoir fed from DN 500mm conduit Bazmaghbyur by gravity.

The water supply pipelines of the settlements are in poor condition. The inner network is laid with steel

pipes which are corroded. The most of the settlements distribution pipelines are deteriorated causing

significant leakages. Non-counted water of the abovementioned communities makes about 88%. The

system consumed water recording is not performed completely.

In 2010 within the framework of “Improvement of W&W systems of the RA settlements” Project funded

by ADB there were performed some works, partially, reconstruction of reservoirs and coming out of them

conduits, distribution system pipelines and valve junc.

4.2. Description of proposed rehabilitation works

The very Subproject aims at rehabilitation of water supply system of Oshakan, Voskevaz, Voskehat rural

communities, providing the inhabitants with safe potable water and improving water distribution and

accounting systems.

Population number in Oshakan, Voskevaz and Voskehat villages, according to 01.01.2012, makes 11788

in total. The clients total number in the rural communities is 2469.

Taking into account the population prospective growth by 2040, assuming 0.43% annual growth, the rural

communities dwellers number is supposed to be 13293 men.

For the settlements, considering also the leakages, the mean daily water demand rate is assumed to be 200

l/day per man.

The average hourly discharge of maximal daily water demand of the rural communities makes

Qav..h=117.4 l/sec.

Based on the technical and economical calculations done in the Preliminary Design, as well as submitted

justifications, in the Detailed Design there have been developed activities on the water supply

rehabilitation.

By the very Detailed Design the works designed for the improvement of water supply system in Oshakan,

Voskevaz and Voskehat rural communities are as follows:

Construction of de50-de200 diameter 39600 lm long polyethylene pipelines

Construction of valve junc. – 43 sets

Construction of private house connections - 23480 lm

Installation of private houses water metering junc. - 2104 sets

According to the agreement between the Contractor, Consultant and rural communities, the mentioned

beneath works should be implemented by the construction completion, in spite of the pipeline diameter

and its function.

1. To restore the asphalt concrete pavement of roads which were previously in favorable

condition, providing the same cover quality,

2. To perform backfilling of the trenches in the destroyed and half-destroyed streets paved

with asphalt concrete, then 10-15 cm gravelling with compaction.

5. BASELINE ENVIRONMENTAL CONDITIONS

5.1 Geographic location and climate of Oshakan, Voskevaz, Voskehat villages of Aragatsotn region

The studied area of Aragatsotn region area is situated premountain zone where the relief is slightly steep,

not so hilly, somewhere partioned by small ravines. The settlements are 3-5 km far south-west from

Ashtarak town, and 20-22 km far from Erevan. The regional center is Ashtarak town.

The climate of the studied area is acutely continental characterized by hot summer and rather cold winter.

The site air average annual temperature is +9,1 C, and absolute minimal temperature reaches +38 C. The

average annual atmospheric rainfalls make 447mm, the maximal 715 mm. In winter the snow average

cover reaches 28 cm, the maximal – 68 cm. The ground freezing maximal depth is 79 cm. The air average

many-year relative humidity makes 62%. The wind average annual velocity is 28m/sec.

The northern part of the area boarders on the south lower slopes of Aragats mountain, where the

geological structure contains Armenian Upland volcanic formations.

Among exogenic phenomena there are surface erosion, change and deepening of the gullies formed due to

the rainfall permanent and temporary flows, and some technogenic phenomena, etc.

The inhabited part of the studied area is situated at 950-1100m elevation marks.

5.2 Biodiversity

The most area lands are under agriculture use with the exception of some little “islands” of wild nature.

The lands soil is commonly brown and semidesert type.

From the geo-morphological aspect the area represents a hilly lava covered plateau with common scoria

wedges and gorges. It is situated within the Kasakh River basin where the relief is commonly channeled

by pre-mountain ravines.

The area geological structure represents the Armenian Upland Upper Pliocene volcanic deposits. The

rocks are of Quaternary period represented by basalts, dacites, tuffs and their clastic sediments. Since the

volcanic formations are subject to intensive weathering, with typical strong fracturing, the ground waters

are infiltrated rather deep - at 15-20m depth.

There are no negative physical and geological phenomena within the area. The region is situated in 9

magnitude seismicity zone.

23

Flora The plant species of the studied areas are introduced by the typical of Aparan and Erevan florisic

region vegetation types, that is meadow, steppe and semi-desert types.

From the true grasses (Poaceae) the couch grass (Phleum sp.), bluegrass (Poa sp.), fescue grass (Festuca

sp.) are widely spread, mainly Artemisia fragrans formation. The steppe species are introduced by

feather-grass, fescue-grass and vegetative formations, with prevalence of Festuca valesiaca, Prairie June

Grass (Koeleria cristata), Stipa tirsa, etc. There is also observed significant presence of thyme species,

Festuca ovina, low sedge, etc. Besides, there are also occur Plantago (plantain), Tragopogon, Taracsacum

(dandelion), Betonica (betony), Vicia (vetch), Trifolium (shamrock), Cirsium (thistle), Euphorbia

(spurge), Papaver (poppy), and from the bush species: Rosa (dog rose), Paliurus (jujube), Acantholimon

(prickly thrift).

From the tree species there occur poplar (Populus), acacia (Robinia), maple (Acer), mulberry (Morus),

wild apricot (Armeniaca), hawthorn tree (Crataegus), willow-leafed pear (Pyrus salicifolia), common

and Caucasian Ash (Fraxsinus excelsior, F.oxycarpa), spirea (Spiraea crenata), Berberis orientalis,

Cotoneaster integerrima, Lonicera iberica, Jasminum fruticans, Ulmus, Prunus, Elaeagnus, willow –

Salix.

Within the studied areas there also occur endangered species like Hohenackeria exscapa (Stev.) K.-Pol,

recorded in the new version of the RA Red Book.

Fauna In the studied area commonly occurred invertebrate species are locust species (Oedopoda

coerulescensd), Oe. Miniata, Pholidoptera satunini, Scintharista notabilis, Tmethis festivus, Spingotus),

crickets (Phytodrymadusa armeniaca), double-wing (Tomomyza araxana, Bombilus schelkovnikovi)

species, and from the scorpions only yellow species (Buttus caucasicus).

From mammals there are widely spread hares (Lepus europaeus), foxes (Vulpes vulpes), and wolves

(Canis lupus). The area widely spread rodents are mouse species (Muridae), especially common field

vole (Microtinae).

From the bird species the widely spread are sparrow (Passeriformes) and falcon (Falconoformes)

species.

From the creepers the typical for the studied area species are Snake-eyed Lizard (Ophisops elegans),

Strauch's (Eremias strauchi) and Transcaucasion (E.pleskei) racerunners, etc

6. ENVIRONMENTAL AND SOCIAL IMPACTS

Due to the implementation of works aimed at the improvement of W&W systems of Oshakan, Voskevaz

and Voskehat villages the expected positive environmental and population health effects are as follows:

water resource protection and sustainable use,

excluding mixing of drinking, irrigation and sewerage water,

preventing, excluding penetration of infectious disease viruses into drinking water,

reduction of drinking water pollution hazard,

providing high drinking water quality,

24

improvement of health condition of population,

water loss reduction,

increasing duration of water supply to population,

introduction of water metering system,

increasing water consumption efficiency.

IEE reveals that the implementation of works aimed at W&W systems improvement in Oshakan,

Voskevaz and Voskehat villages of Aragatsotn region will have no harmful effects on the selected for this

purpose area - either landscape or flora and fauna.

The probable negative effects might be mainly caused by construction works implementation, and

expected to do little damage and be temporal. To prevent negative impacts, or facilitate them there have

been developed facilitating measures which are involved into the EMP.

EMP is the integral part of bidding document and based on the IEE the expected negative impacts are as

follows:

air pollution

noise

traffic and pedestrian roads damage and loading

soil erosion and soil eroding processes

environment pollution by construction and household waste

soil and water resources pollution by fuels and lubricants,

soil and water resources pollution by chlorine.

Subproject implementation will have positive social effects directly improving the population life quality

providing sustainable and reliable water supply and water resource rational use for about 11788 men.

7. ENVIRONMENTAL IMPACT MITIGATION MESUERES

The probable harmful impacts on the environment and people’s health, caused by the works aimed at the

W&W internal system improvement of Oshakan, Voskevaz, Voskehat rural communities, depend on

construction works of water pipeline trenches and pits for control and water measuring junc.

To prevent soil erosion and eroding processes the preventive measures should be performed on slopes

protection on the inclined areas designed for the pipe laying, providing minimal short time of keeping

open the trenches and pits made for the pipelines and control and water measuring junc.

The slopes protection measures should be performed to prevent soil eroding processes on the areas close

to the riverbeds.

After construction work completion the sites should be recovered by performing the mentioned beneath

activities:

- remove the excess soil mass and building material from the construction sites,

25

- recover the asphalt – concrete pavement, providing its previous good condition and quality,

- provide graveling with compaction on the streets with damaged and half-destroyed asphalt-

concrete pavement, as well as on dirt roads.

To prevent the topsoil layer damage, or landscape degradation, the topsoil should be stored on the

assigned site, thereafter used for the areas restoration. The construction site should be cleaned from the

household ad construction waste providing the landscape previous state.

To prevent the soil and water resources pollution by fuels and lubricants, the latter should be stored on

the area isolated from soil and water resources, in special tanks. Special containers should be prepared for

the utilized lubricants, which thereafter will be disposed in landfills or places for reprocessing.

To prevent the environment pollution by construction waste and excess soil mass they should be disposed

on special sites according to the agreements signed beforehand between community head and disposal

site superintendent.

To avoid water and soil resources pollution by chlorine, the works on chlorine washing and disinfection

should be arranged considering special calculations. Chlorine handling needs treating the appropriate

way, following the established technological procedures. After washing the pipes, the chlorine outflow to

the surface water unit, or land area, should be controlled according to the designed mode and calculation.

Water quality change. While performing the environment monitoring the supervision on water quality

and residual chlorine should be arranged.

To minimize dust emission caused by construction works the site should be regularly watered.

To prevent noise impact the schedule should be developed on limiting the night works on the residential

areas, avoiding noisy vehicles and equipment use, installing mufflers, if necessary.

To minimize the population disturbance caused by roads damage and loading, the special parking lots for

trucks should be allotted, and the construction works should be performed by stages, arranging population

awareness campaign, including placing special traffic signs, providing bypasses, or barricades.

To provide population and builders’ safety and prevent risks during the construction, the unauthorized

persons’ entrance to the construction site should be controlled, warning signs should be placed in the

accident-prone sectors, regular inspection of equipment by qualified specialists should be performed,

including safety audits, first aid and safety courses organization for builders.

The affected parties and local population should be appropriately informed through public consultations

on the coming activities, their schedules and all measures involved in the EMP, since information lack

can bring forth discontent causing complains. Providing the communities’ participation in the Subproject

will minimize the disturbance caused by construction works to the social life of community.

Potable water quality change: EMP should involve monitoring of water quality and residual chlorine

level.

To provide potable water quality in Oshakan, Voskevaz and Voskehat rural communities, the AWSC

should perform routine sampling from the springs feeding the communities, testing the water for all

criteria required by the MoH. Water quality monitoring is also performed by the State Hygiene Anti-

Epidemic Inspectorate according to the document “Potable water. Requirements on water quality of

centralized water supply systems. Sanitation rules and norms of quality inspection № 2-III-A2-1”

26

(recorded on 28.12.2002), which specifies the potable water quality requirements, including the rules of

quality inspection of water produced and supplied through water distribution systems to the residential

areas.

Since water disinfection is performed by chlorine, the monitoring of residual chlorine level is also of great

importance.

8. INSTITUTIONAL FRAMEWORK OF ENVIRONMENTAL MANAGEMENT

To perform the proposed facilitating measures, the obligations on their arrangement have been allocated

between the agencies, as follows:

Executive agencies, which are responsible for implementation of the measure.

1. To perform this special task the implementing unit (JV of HGSN and JINJ) in the Designing stage

should provide the procurement of all required agreements and permissions from the corresponding

public administrative and local self-governing bodies before civil works distribution according to the

tender terms.

- environmental expertise (if necessary),

- consent of Protection Agency of Historical and Cultural Heritage, in case of expected impact on

the latter.

2. The implementing units in the construction stage (Contractors) will covenant to physically implement

the specified in the MEP facilitating measures, as well as procure all permissions and consents relating to

the civil works implementation, which are as follows:

- local municipal bodies’ written consents on the specified sites for household and construction

waste disposal,

- consent of Historical and Cultural Heritage Protection Agency, in case of historical, cultural or

ancient monuments occurrence during civil works implementation.

3. Before civil works startup, if necessary, the mentioned beneath permissions and certificates should be

procured by ADB/PMU:

- certificate on land use right registration

- water use permission, if necessary.

Controlling agencies, which are responsible for controlling the executive units to provide

implementation of the EMP measures by the latter

1. The environment and safety specialists of “AWSC” CJSC/ADB PIU will be responsible to

supervision over the implementation of mitigation measures specified in EMP. The mentioned experts

will regularly perform sites visits to supervise the proper implementation of works and corresponding

activities on mitigating the impacts. During the checkups the probable omissions will be revealed by the

check list , as well as violations of mitigation measures implementation by Contractors.

“AWSC” CJSC /ADB PIU is also entitled to demand and checkup the availability and validity (expiration

date) of all permissions, complete implementation of impact facilitating measures and monitoring

27

according to the EMP in terms of ADB environmental instructions and the RA nature protection and

social legislation.

2. The JV of HGSN and JINJ are also to carry out the supervision over the implementation of mitigating

measures during civil works implementation. The environmental specialist of Consultant should make

visits to control the implementation of EMP.

State monitoring agencies, which are responsible for observing the extent and efficiency of

EMP implementation and making corrections in the project, if needed.

The state agencies, which are to carry out monitoring, are as follows:

- State Environmental Inspectorate of the RA MoNP,

- State Hygiene and Anti-Epidemic Inspectorate of the RA MoH,

- Historical and Cultural Heritage Protection Agency of the RA MoC, if necessary,

- The RA local self-governance bodies,

- The RA MoT&C.

The amounts envisaged for implementation of environmental measures included in the EMP are included

in the detailed design.

Implementation of mitigating measures for environmental impacts will be controlled regularly through

visits to the construction sites. With the help of the specially developed check list the gaps and drawbacks

will be discovered.

In case of not implementing or infringing the implementation of the mitigating measures, after warning,

the next payment will be terminated until the infringement is completely eliminated.

9. ENVIRONMENTAL MANAGEMENT PLAN

The EMP will be based on the results of IEE prepared by subproject and will include appropriate

mitigation measures.

EMP consists of two components:

1. Mitigation measures and institutional responsibilities for implementation;

2. Environmental monitoring.

The Contractor should strictly follow the environmental mitigation measures prescribed in the EMP. The

costs foreseen for the implementations of all the measures prescribed in the EMP are included the total

value of the Contract and reflected in the bill of quantities.

Notice on the failure to implement measures prescribed by the Technical Supervision Company (TSC) or

the Client would be sent to the Contractor in written. After the Notice to Correct, the next recorded

violation would trigger charging of liquidated damages in the amount of 0,1% of the total value of the

contract. The liquidated damages do not relieve the Contractor from remedying the violation. The

recorded violation should be remedied in two working days period. Liquidated damages would be

retained from the next Performance Certificate and after the completion of the construction activities the

28

liquidated damages for the recorded violation will be retained from the Retention Money. In case of three

liquidated damages the Contract could be terminated unilaterally.

Above described remedies of EMP violation will be included in the contracts for provision of works

concluded by AWSC under the W&W project.

The environmental management matrix is presented in Appendix A.

3. INTRODUCTION

The very report is developed for the Subproject on the Improvement of W&W Systems in Amberd,

Aygeshat, Dasht, Doghs, Lernamerdz, Aghavnatun villages of the RA Armavir region, the design of

which has been performed by the JV of HGSN and JINJ LLCs. The Water supply systems rehabilitation

involves activities on reconstruction and repair of water distribution systems, as well as construction of

new water pipelines, regulating and water measuring junc.

As a result of construction work implementation, as well as further operation and maintenance of the

water supply systems there might be negative impacts on the environment.


39

It is expected that the impacts during construction work implementation will be minimal and temporary,

probably involving vegetation cut, soil erosion, air, soil and water resource pollution by lubricants and

chlorine compositions, as well as household and construction waste.

At the Operation Stage the environmental impact, mainly expected because of improper execution of

operation requirements, will decrease.

The activities aimed at improvement will be considered environmentally friendly in case of water

resource conservation, as well as their rational and sustainable use.

4. SCOPE OF WORKS


The total length of water supply distribution pipelines in Amberd, Aygeshat, Dasht, Doghs, Lernamerdz

and Aghavnatun rural communities is 54 km. The community water supply is performed from

Bazmaghbyur and Ghazaravan ground water springs of Ashtarak region.

To provide water supply through the conduits coming from the ground water intake structures the

mentioned beneath works were performed for the Subproject communities.

For Amberd community – 4 connections with 150, 125, 100 and 75 mm steel pipelines,

For Aygeshat community – 5 connections, the main of which are considered 150 mm and

63 mm polyethylene feeding pipeline,

For Dasht community – 8 connections, where the main ones are performed with 100 mm,

75 mm and 50 mm diameters steel pipes,

For Doghs community – 2 connections, with 150 mm and 125 mm diameters steel pipes,

For Aghavnatun community – 2 connections with 200 mm and 50 mm diameters steel

conduits,

Water supply of Lernamerdz community is performed at one point through 200 mm

diameter steel pipe.

The water is directly supplied to the distribution system through water conduit.

The water supply in the residential areas are performed through the pipelines which are in poor condition.

The inner network is entirely laid with steel pipes which are corroded. The most of the settlements

distribution pipelines are deteriorated due to which the leakages are significant. Non-counted water of the

abovementioned communities makes about 88%. The system consumed water recording is not

performed completely.




In 2010-2011 by the mutual efforts of “AWSC” LLC and communities in Aygeshat and Aghavnatun

villages there were reconstructed polyethylene pipelines and distribution systems, including also

installation of private houses water metering junctions in Aghavnatun community.

4.2.Description of proposed rehabilitation works

The very Subproject aims at rehabilitation of water supply system of Amberd, Aygeshat, Dasht, Doghs,

Lernamerdz and Aghavnatun rural communities of the RA Armavir region, providing the inhabitants with

safe potable water and improving water distribution and accounting systems.

41

The population number in Amberd, Aygeshat, Dasht, Doghs, Lernamerdz and Aghavnatun villages,

according to 01.01.2012, makes 10652 in total. The clients total number in the rural communities is

1851.

Taking into account the population prospective growth by 2040, which assumes 0.43% annual growth, the

rural communities dwellers number is supposed to be 11809 men.

5.1 Geographic location and climate of Amberd, Aygeshat, Dasht, Doghs, Lernamerdz and

Aghavnatun villages of the RA Armavir region

The studied area of the RA Armavir region is situated within the premountain flat land, at average

elevation, where the relief is slightly hilly, somewhere channeled by small ravines. The Subproject

settlements are 25-30 km far north-east from Armavir town, and 20-22 km far north-west from Erevan.

The area is characterized by hot summer, with 21.50C average monthly temperature in July and cold

windless winter with January 3.8ûC average monthly temperature. The air absolute maximal temperature

is +41 C, and absolute minimal -31 C. The average annual atmospheric rainfalls make 280-340mm. The

snow average cover reaches 42 cm. The ground freezing depth is 0.50-0.70 m, subject to the absolute

elevation. The air average many-year relative humidity makes 59%. The wind average annual velocity is

1.8 m/sec.

Considering the geo-morphological aspect the area represents accumulative relief, slightly gradient plain.

It is situated in the east part of Ararat valley premountain zone, within the terrace of Araks River left bank

(accumulative terraces, flood plain).

Among exogenic phenomena there are surface erosion, water flooding, caused by the rainfalls, change

and deepening of the gullies formed due to the rainfall permanent and temporary flows, and some

technogenic phenomena, etc.


5.2 Biodiversity

The predominant type of the area soils is brown, represented by gravel and stony, somewhere carbonate

cemented and hydromorphic saline soils, formed on the lake-alluvial deposits.

In the west, south and east the area bounds on the Ararat valley the geological structure of which

represents the Armenian Upland Upper Pliocene alluvial and proluvial lake-river, flood deposites. The

latter are introduced by clay layer groups which in some places pass into gravel, sand and clay-sand

sublayers with 5-10 cm, and somewhere more thicknesses.

The sediments section in its turn is covered by the Quaternary period alluvial-diluvial sediments, or

volcanic complexes of andesite-basalts, dacites.

44

The area feeding big water pulse is the Araks River with its Metsamor and Vedi tributaries. From the

hydrogeological aspect the area is rich in ground waters ocurring at different depth, starting from 0-5m,

100 and deeper levels. The ground water availability depnds on lake-river formations and cracked

andesite-basalts.


magnitude potential seismicity zone.

Flora The area vegetation is introduced by semi-desert and desert plant species, like sage-brush

ephemers and halophiles, typical of Erevan floristic region vegetation types, developed on the sand-clay

bedrocks. that is meadow, steppe and semi-desert types.

Within this landscape zone there are registered about 130 plant species, out of which the dominant ones

are lanceleaf water plantain (ALISMA LANCEOLATUM), common arrowhead (SAGITARIA

SAGITTIFOLIA L.), threeleaf arrowhead (SAGITARIA TRIFOLIA L.), bean trefoil (COUSINIA

TENELLA), salt-wort (SALSOLA TAMAMSCHJANAE), spinach (SPINACIA TETRANDA), milk-

vetch (ASTRAGALUS PARADOXUS), fenugreek (TRIGONELLA CAPITATA), wheat (TRITICUM

ARARAICUM), tamarisk (TAMARIX), tamarisk (TANARIX OCTANDRA), etc.

Out of wild useful plant species there are thorn apple (Datura stramonium), squirting-cucumber

(Ecballinum elaterium) and Syrian rue (Reganum harmala).

The area endangered species are sweet sedge (Acorus calamus L.), bindweed (Connvolvulus commutatus

Boiss), lettuce (Lactuca Takhtadzani Sosn), milk-vetch (Astragalus paradoxus), etc.

Fauna In the studied area there 113 commonly occurred vertebrate species, the dominant of which are

widely spread in Armenia Crocidura (white-toothed shrews), Vulpes vulpes L. (fox), Cricetus auratus

Nat. (golden hamster), Mucrotus arvalis Pall. (field mouse), Perdix perdix L.(partridge), Grus grus L.

(crane), Armenian Gull (Larus armeniacus But.), etc.

The area widely spread vertebrates are marsh frog, grass snake, levantine, magpie, fox, wolf, ermine, out

of invertebrate: ants, crickets, moths, blue butterflies, cabbage white butterflies, etc.

Among the species recorded in the Red Book there are Long-eared hedgehog (Erinaceus auritas Gmelin),

Mehely's Horseshoe Bat (Rhinolophus Mehelyi), Marbled polecat (Vormela peregusna peregusna Guld),

Glossy Ibis (Plagadis falcinellus Linneaus).


Due to the implementation of works aimed at the improvement of water supply systems of Amberd,

Aygeshat, Dasht, Doghs, Lernamerdz and Aghavnatun villages, the expected positive environmental and

population health effects are as follows:






45






IEE reveals that the implementation of works aimed at water supply systems improvement in Amberd,

Aygeshat, Dasht, Doghs, Lernamerdz and Aghavnatun villages of the RA Armavir region will have no

harmful effects on the selected for this purpose area - either landscape, or flora and fauna.

The negative effects might be mainly caused by construction works implementation, with little damage

and carrying temporal character. To prevent negative impacts, or facilitate them there have been

developed facilitating measures which are involved into the EMP.

EMP is the prime part of bidding document and based on the IEE the expected negative impacts are as

follows:

air pollution

4. SCOPE OF WORKS


The total length of water supply distribution network in Musaler, Shahumyan, Shahumyan P/F, Ptghunk,

Norakert rural communities is about 47 km. The community water supply is performed from

Bazmaghbyur and Ghazaravan ground water springs of Ashtarak region.

10

The water supply of north part of Musaler village is performed by pumps, and water supply of the south

part of the settlement is performed through the village main conduit which also has connections providing

airport water supply which is performed by pump at the operation of which Musaler is deprived of water

supply.

There were 5 connections performed on the water conduit which comes from groundwater intake

structure fed Shahumyan community water supply system, 3 of which are the main ones, at which 2

connections are made by 100 mm diameter pipes and 1 connection – by 75 mm diameter pipes.

To supply water for Shahumyan P/F there were 2 connections performed by 250 and 80 mm diameter

steel pipes to the water conduit running to Aygek village.

Ptghunk and Norakert communities water supply is performed through 150 mm diameter cast-iron pipes

fed from Ghazaravan conduit.

The water is directly supplied to the distribution system through water main.

The water supply in the residential areas is performed through the pipelines which are in poor condition.

The inner network is entirely laid with steel pipes which are corroded. The most of the settlements

distribution pipelines are deteriorated due to which the leakages are significant. Non-counted water of the

abovementioned communities makes about 88%. The system consumed water recording is not performed

completely.




In 2010 the reconstruction works of pipelines were performed at the expense of Musaler community.

4.2. Description of proposed rehabilitation works

The very Subproject aims at rehabilitation of water supply system of the RA Armavir region Musaler,

Shahumyan, Shahumyan P/F, Ptghunk and Norakert rural communities, providing the inhabitants with

safe potable water and improving water distribution and accounting systems.

The population number in Musaler, Shahumyan, Shahumyan P/F, Ptghunk and Norakert villages,

according to 01.01.2012, makes 11319 in total. The clients total number in the rural communities is 1870.

Taking into account the population prospective growth by 2040, which assumes 0.43% annual growth, the

rural communities dwellers number is supposed to be 12764 men.

5.1 Geographic location and climate of Musaler, Shahumyan, Shahumyan P/F, Ptghunk and Norakert

villages of the RA Armavir region

The studied area of the RA Armavir region is situated within the premountain flat land, at average

elevation, where the relief is slightly hilly, somewhere channeled by small ravines. The Subproject

settlements are 30 km far north-east from Armavir town, and 8-10 km far north-west from Erevan.

The area is characterized by warm to hot summer, with 21.50C average monthly temperature in July and

cold windless winter with January 3.8ûC average monthly temperature. The air absolute maximal

temperature is 41 C, and absolute minimal -31 C. The average annual atmospheric rainfalls make 280-

340 mm. The snow cover reaches 42 cm. The ground freezing depth is 0.50-0.70 m, subject to the

absolute elevation. The air average many-year relative humidity makes 59%. The wind average annual

velocity is 1.8 m/sec.







Among exogenic phenomena there are surface erosion, water flooding, caused by the rainfalls, change

and deepening of the gullies formed due to the rainfall permanent and temporary flows, and some

technogenic phenomena, etc.


5.2 Biodiversity

The predominant type of the area soils is semi-desert brown, represented by gravel and stony, somewhere

carbonate cemented and hydromorphic saline soils, formed on the lake-alluvial deposits.

In the west, south and east the area bounds on the Ararat valley the geological structure of which

represents the Armenian Upland Upper Pliocene alluvial and proluvial lake-river, flood deposits. The

latter are introduced by clay layer groups which in some places pass into gravel, sand and clay-sand

sublayers with 5-10 cm, and somewhere with more thicknesses.

14

The sediments section in its turn is covered by the Quaternary period alluvial-diluvial sediments, or

volcanic complexes of andesite-basalts, dacites.

The area feeding big water pulse is the Araks River with its Metsamor and Vedi tributaries. From the

hydrogeological aspect the area is rich in ground waters occurring at different depth, starting from 0-5m,

100 and deeper levels. The ground water availability depends on lake-river formations and cracked

andesite-basalts.

Flora The area vegetation is introduced by semi-desert and desert plant species, like sage-brush ephemers

and halophiles, typical of Erevan floristic region vegetation types, developed on the sand-clay bedrocks,

that is meadow, steppe and semi-desert types.

Within this landscape zone there are registered about 130 plant species, out of which the dominant ones

are lanceleaf water plantain (ALISMA LANCEOLATUM), common arrowhead (SAGITARIA

SAGITTIFOLIA L.), threeleaf arrowhead (SAGITARIA TRIFOLIA L.), bean trefoil (COUSINIA

TENELLA), salt-wort (SALSOLA TAMAMSCHJANAE), spinach (SPINACIA TETRANDA), milk-

vetch (ASTRAGALUS PARADOXUS), fenugreek (TRIGONELLA CAPITATA), wheat (TRITICUM

ARARAICUM), tamarisk (TAMARIX), tamarisk (TANARIX OCTANDRA), etc.

Out of wild useful plant species there are thorn apple (Datura stramonium), squirting-cucumber

(Ecballinum elaterium) and Syrian rue (Reganum harmala).

The area endangered species are sweet sedge (Acorus calamus L.), bindweed (Connvolvulus commutatus

Boiss), lettuce (Lactuca Takhtadzani Sosn), milk-vetch (Astragalus paradoxus), etc.

Fauna In the studied area there 113 commonly occurred vertebrate species, the dominant of which are

widely spread in Armenia Crocidura (white-toothed shrews), Vulpes vulpes L. (fox), Cricetus auratus

Nat. (golden hamster), Mucrotus arvalis Pall. (field mouse), Perdix perdix L.(partridge), Grus grus L.

(crane), Armenian Gull (Larus armeniacus But.), etc.

The area widely spread vertebrates are marsh frog, grass snake, levantine, magpie, fox, wolf, ermine, out

of invertebrate: ants, crickets, moths, blue butterflies, cabbage white butterflies, etc.

Among the species recorded in the Red Book there are Long-eared hedgehog (Erinaceus auritas Gmelin),

Mehely's Horseshoe Bat (Rhinolophus Mehelyi), Marbled polecat (Vormela peregusna peregusna Guld),

Glossy Ibis (Plagadis falcinellus Linneaus).


Due to the implementation of works aimed at the improvement of water supply systems of Musaler,

Shahumyan, Shahumyan P/F, Ptghunk and Norakert villages of the RA Armavir region, the expected

positive environmental and population health effects are as follows:

IEE reveals that the implementation of works aimed at water supply systems improvement in Musaler,

Shahumyan, Shahumyan P/F, Ptghunk and Norakert villages of the RA Armavir region will have no

harmful effects on the selected for this purpose area - either landscape, or flora and fauna.

The negative effects might be mainly caused by construction works implementation, with little damage

and carrying temporal character. To prevent negative impacts, or facilitate them there have been

developed facilitating measures which are involved into the EMP.

EMP is the prime part of bidding document and based on the IEE the expected negative impacts are as

follows:
