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.
1. ENVIRONMENTAL AND SOCIAL SAFEGUARD DOCUMENTS
In accordance with the ADB Environmental policy (November , 2002) the Subproject is ranked to B category which does not need extended EIA, excluding also Environmental expertise, according to the RA law on “Environmental Impact Assessment” (issued on November 20, 1995) and the RA Government decree “Threshold of environmental impact activities subject to expertise” (N-193, 30 March 1999). For starting the construction stage of the project positive expert conclusion of the Environmental expertise SI under the RA MNP is required.
2. INTRODUCTION
This report is developed for the Subproject on the Improvement of W&W Systems in Sevan town of Gegharkunik region, the design of which has been performed by the JV agreement of HGSN and JINJ LTDs. The works will be implemented in the external water supply system of Sevan town to increase the supplied water amount and to improve the level of the rendered services, making technical, social-economic, environmental and institutional improvements. The detailed design was developed within the framework of the VI sub-project on “Improvement of W&W systems of Gegharkunik region settlements”, according to the ToR provided by AWS CJSC and the conclusion of hydrogeological investigations made in 2012 (author – H. Aghinyan).
1 The number of towns and villages may change subject to further detailed assessments.
Sub-project VI, Package VI.4 Environmental management plan 7 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
The following works are planned in the external water supply system: Assess the capacity of additional water sources in upstream basin of the Dzknaget River. Plan water intake structures adjacent to the assessed water sources. Transmit the extra water quantity to the currently operating Dzknaget-Sevan gravity system. Provide the customers of Sevan town with 24-our water supply. 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. It is expected that the impacts during construction work implementation will be the least and temporary, probably involving violation of Dzknaget’s aquatic eco-systems, eradication of biodiversity, coastal 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 effects as a result of water supply system improvement are expected to be long-term, mostly positive, such as excluding potable and wastewater mixture, 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. Below the description of possible impacts and facilitating measures required during different stages of Water Supply Systems Rehabilitation Project is provided. Design 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, requirements on obtaining the RA MoNP and other Ministries’ agreements, as well as fulfillment of executive parties’ contractual commitments during all stages. The Design documentation includes adequate environmental and social articles and separate Matrix of the very EMP Subproject. The Project Consultant is in charge to follow the appropriate statements of the RA Environmental and social legislation, as well as ADB instructions and strategy requirements.

Sub-project VI, Package VI.4 Environmental management plan 8 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
Operation Stage The Contractor should strictly follow the requirements on environmental impact mitigation measures, which are involved in the EMP. During the Construction Stage the Operation should be performed in accordance with the Operational Rules and Standards.
3. SCOPE OF WORKS
4.1 Description of existing water supply systems External water supply system At present Sevan town water supply is carried out from Lchashen deep wells served by AWSC and from spring intake structures in upstream Dzknaget, accordingly through Lchashen-Sevan and Dzknaget-Sevan water mains (the latter is connected to the former Arevik-Sevan water main). The main part of the water amount supplied to Sevan town is given from Lchashen deep wells through Lchashen-Sevan 500mm steel water main, by two-stage pumping. There are three deep wells, with about 60l/s discharge each; however only two wells are operating presently. Water from the deep wells is supplied to the pump station built recently in Gomadzor district, from where it is pumped to the 2x2000m3 (1960m), and 1x1000m3 (2000m) DRRs. Though the discharge of Lchashen deep wells is enough for providing water for drinking- household, fire prevention use and emergency reserve for the town, the operation costs of the system are rather high because of pumping. From Dzknaget sources water is transmitted through 24km long 500-400mm steel and 9.5km long 250-225mm polyethylene pipes to the 1000m3 DRR at 2000m altitude and from there is supplied to the distribution network by gravity. Because of the Lake level increase the segment “Akhtamar-Harsnaqar” of Arevik-Sevan water main has appeared under water. The mentioned segment passes along Dilijan-Sevan present highway. With financial support of ADB, last year by-passing of this segment was implemented with de225mm polyethylene pipes, which was connected to the existing 400mm steel pipe in Tsamaqaberd district. Besides, the Arevik-Sevan distribution node located in the crossroad of Chambarak- Tsovagyugh roads was rehabilitated. The discharges of Dzknaget springs vary depending on seasonal variations. Therefore, during summer months water supply to some districts of the town is implemented only from Lchashen deep wells, mechanically and water quantity is not sufficient.
Internal water supply network The town’s water supply network is about 25km long and is implemented with 100400mm cast iron and steel pipelines. Inter district waterlines are implemented with 50100mm. steel pipelines.
Sub-project VI, Package VI.4 Environmental management plan 9 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
At present, by the order of AWS CJSC and with the loan of EBRD rehabilitation works are being carried out in the distribution network of the town. Water supply of the main apartment buildings of the town is implemented with small local pump stations, except I - VI micro- regions, the supply of which is implemented from DRR by gravity. During the recent years, thanks to the loan provided by ADB, distribution network water lines in some streets were repaired and rehabilitated.
Wastewater system The town operating wastewater network is about 22km. It is implemented from 150800mm steel, cast iron, concrete and asbestos-cement pipes. The wastewater network is in poor condition and needs renovations. The town wastewater is collected through 30km long collector and transported to Kaghsi wastewater treatment plant, which presently does not operate and wastewater is discharged into the Hrazdan River without treatment.
4.2 Description of proposed rehabilitation works For the development of the detailed design the results of the studies carried out for revealing underground fresh water resources in the upstream Dzknaget River, assessing their qualitative and quantitative characteristics served basis. The studies were carried out in the Dzknaget River’s valley sites (about 400m downstream the joining place of Kyoroghli tributary with the river). In this site route mapping, experimental filtration and water metering activities were carried out, a series of prospecting boreholes were drilled and recorded. Based on the carried out studies, the following was proposed: To construct a horizontal drainage under-flow water intake structure in the Dzknaget River’s valley site. To construct about 1.7km long water main, through which water will be transported from the intake structure to the operating Dzknaget-Sevan water main.
The subproject layout is depicted in Appendix 7.
Underground horizontal under-flow water intake The DD plans underflow horizontal water intake structure. The structure consists of two branches: 500mm steel and 300mm polyethylene pipes, with 250m and 70m lengths accordingly. The branches are installed in parallel to the river, on average 3m and 25m distances from the bed. Observation chambers are planned to be constructed starting from the beginning part of the structure, as well as in the route bending parts, at 50.0m distances from each other, having the purpose of future repair of possible cloggings and carrying out main prospecting studies during the long-term operation.
Sub-project VI, Package VI.4 Environmental management plan 10 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
The non-return, filtering layers around the water intake pipelines shall be implemented with a special attention and without design changes. The layers shall be fully installed only by hand. The intake pipes are installed in the 200-250mm grained washed pebble layer, over which 25cm thick layer of the same pebble is installed. Sequentially, over the pebble layer, a 50cm thick and 70-150mm grained washed pebble layer, a 50cm thick and 20-50mm grained, a 25cm thick and 2-10mm grained washed pebble layers are installed, and then a 15cm thick and 1.2-2.0mm grained washed sand layer. Over the last filtering layer the sand-pebble side stored excavated layer is installed, after which the route is recultivated throughout its full length and rehabilitated with vegetative soil layer. According to the hydraulic calculations, to collect the required water amount, opening of 20mm wide and 75mm long holes with chequer-wise order is planned on pipes at 100mm distances from each other. At the end of the discharge pipe from the water intakes it is planned to construct a regulating valve chamber, for regulation of the collected water, emptying the water intakes and removing the extra water. The DD plans construction of sanitary protection zone for the water intakes. According to the RA Minister of Health Decree No. 803 of 29.11.2012, the sanitary protection zones of drinking-household surface water sources shall be consisted of I, II and III zones; however the last two zones are for certain cases and are not related to the underflow water intake designed by us. The borders required for the I sanitary zone are as follows: 1. Upstream the water source - not less than 200.0m, 2. Downstream the water source - not less than 100.0m, 3. Along the bank bordering with the water source - not less than 100.0m, 4. Along the bank opposite the water source - not less than 50.0m,
However, the location of the sanitary protection zone of the underflow intake designed by us does not allow us to meet the conditions under items 3 and 4, since along the bank bordering the intake, at on average 50.0 meters, an earth highway passes, which is envisaged for operation of the spring intakes by AWSC. Directly after the latter the mountain slope starts. The same situation is with the opposite bank, without highway.
Since chemical contamination in the intake area is excluded (there are no industrial facilities in the surroundings up to 50 km radius), and the possible microbial contamination in the area is related to livestock grazing, human activity, and to exclude this, the intake area will be fenced and monitored by AWSC. On the other hand, the slopes stretching along the Dzknaget river banks are covered through their whole length with mildly sloped (for Armenian conditions) rock soils covered by grass layer. Naked rocks are almost absent. Therefore, during the spring snow melt and autumn heavy showers the turbidity in the river water does not change tangibly (according to the data in the bulletin of the RA MNP Monitoring Center, the river water turbidity varies in a range of 0.8-18.8mg/l), which means that slope washing does not take place and the turbidity increase is a result of the river bed sediment movement related to the increase of water quantity. And since
Sub-project VI, Package VI.4 Environmental management plan 11 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region the underflow intake is located in the river floodplain at 3 m depth, the snow melts and flood waters do not represent a threat to water quality.
For such favorable conditions the standard existing in the RA (SNiP 2.04.02-84-water supply: external networks and structures; item 10.12) allows to reduce the width of the sanitary zone up to 25m and 15m. The fence of the sanitary zone is implemented from barbed wire, on steel pipes installed at 3.0m distance from each other. The height of the fence is 1.5m, with 0.15m inter-wire distance. The site of the sanitary protection zone is at 0.7km distance from summer cattle sheds in the direction opposite to river flow and at 2.0km distance in the river flow direction, located out of the river’s floodplain area. The elevations of the site are within the range of 2098.0m- 2084.0m. Figure 1 below show the valley site of the Dzknaget River where the underground drainage horizontal structure is to be designed.
Figure 1: Dzknaget River’s valley sites Designed water main The DD plans construction of a new 250mm polyethylene water main form the regulation chamber located in the water intake’s sanitary protection zone until the beginning of Ddmashen gorge. The new pipeline will join the operating 300mm Ddmashen-Sevan steel water main. The route of the designed water main passes along earth road in parallel to the existing 500mm Dzknaget-Sevan water main, at 2.0-5.0m distance. Its total length is 1700.0m. The route of the constructed main crosses in some places the Dzknaget river and the brooks flowing into it. In the crossing places steel casing pipes are planned. Excavation of the water main trench is planned up to 1.75m depth. Before laying the pipes into the trench, it is to be cleaned from extra soil, leveled, then a 10cm thick bedding sand layer is to be implemented, after which the pipe can be laid, filling over it a 15cm thick protective sand layer. After backfilling of the trench leveling and compaction along the route shall be done.

4. BASELINE ENVIRONMENTAL CONDITIONS
5.1 Geographic location and climate of Sevan town Town Sevan is situated in Geghanqunik Marz, at 1925m altitude above the sea level, on north- western shore of Lake Sevan, at 65km distance from Yerevan (Figure 2). The number of population in the community is 24,000 (or 3,900 households) as of 01.01.2013. It is built up with 1-2-storey private houses and apartment buildings. Geographically Sevan is one of the most mountainous regions of Armenia and is located in the junction of Areguni, Pambak and Geghama mountain ridges. The region has continental climate, with cool summers and cold winters. Absolute maximum air temperature is +33C: Absolute minimum air temperature is - 32C: Annual precipitation is 588mm. Western and north-western winds with 3.2m/s velocity predominate here. During 20 years, winds of 27m/sec velocity are possible. Snow cover pressure 150kg\m2. Maximum land freezing depth is 114cm (Lake Sevan level). From dangerous physical-geological phenomena there are stone falls, stone slides, flooding in riparian zone, side and bed erosion in beds. Intense shore deterioration processes take place along the whole length of Lake Sevan shore. Silty rocks are corrosive to the concrete media. The area of direct implementation of the works planned under the project is the Dzknaget River valley, which is located at 15.0km distance from Sevan National Park.
Sub-project VI, Package VI.4 Environmental management plan 13 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
Figure 2: Geographical location of Sevan town and the Dzknaget River Dzknaget is one of the major tributaries of Sevan. It starts from northeastern slopes of Pambak mountain ridge, at 1310m elevation. The river’s length is 22 km, its catchment basin area is 90.5km2. The feeding of the river is mainly snow-rain (82%), with spring freshets, during which 75% of annual run-off is formed. Average annual runoff is 1.11m3/s, flow is 35mln. m3. After the fall of Lake Sevan level river erosion has intensified and 6-10m deep valleys have formed in the Dzknaget river. In downstream of the river not only depth subsurface erosion but also lateral erosion is strong, resulting in washout of the river banks and forming meanders. In different parts of the Dzknaget area, mainly in valleys, shifts and stone slides of various scale occur.
5.2 Biodiversity Sevan basin geographical position, unique climate and variety of flora have created a suitable environment for fauna.
Fauna The marz area is located in Geghama floristic region. It includes unique and endangered and endemic species of Armenian flora. The fauna is divided into two big groups – aquatic and land. From the animal category, there are the following species: mammals (34 species), birds (267 species), amphibious (3 species), reptiles (17 species) and fishes (9 species).
Sub-project VI, Package VI.4 Environmental management plan 14 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
Biodiversity of the Dzknaget River In the source of the Dzknaget river the bottom soil is 70% pebble and gravel. Moss level on stones is insignificant, there are not sunk macrophites. At the river outlet soil is 100% pebble, gravel and grit. Study of the Dzknaget’s biodiversity was done in 2012 by the Institute of Hydroecology and Ichtiology of the RA NAS. According to the study results, total number of benthos animal species is 1172 individual/m2, and biomass is 3,14 g/m2. Therewith, 39% of biomass are Ephemeroptera of Baetidae, Ephemerellidae, Ceanidae and Heptageniidae family. The next group by biomass is beetles of Elmidae family, which compose 26% of total biomass. Total number of benthos animal species at the river estuary is 2035 individual/m2, and biomass is 3,81 g/m2. Number of larvae of Chironomidae is the greatest - 1728 individual/m2 or 85% of total number of benthos 85%. By biomass Tipulidae are predominant (2,5 g/m2). The reason for such a change in qualitative and quantitative composition of the benthos of source and estuary is probably inflow of wastewater and agricultural polluted water into the water basin from the residential areas located along the river valley. The periphyton on stones is of both green and grey tint, which evidences on the presence of certain organic pollution.
Quality of water at the source of the Dzknaget river by BOD5 index (2.3mg/l) and biological family index (5.6 units) is estimated as moderately polluted. As a result of studies of macrophyte population hydrophytes were not recorded in the source of the river, as well as in mid-stream. At the river estuary very small quantity of Batrachium trichophyllum was revealed (h – 1, s -2). According to the quantitative and qualitative indicators of macrophytes, the saprobic level in this section of the river has been estimated as betta-meсosaprobic (S - 2). During ichtiological studies in the Dzknaget river, the following fish species were revealed: Carassius auratus gibelio, Varicorhinus capoeta sevangi, Barbus goktschaicus and Alburnoides bipunctatus armeniensis.
Flora of the direct impact area The direct impact area includes the following parts: The underflow horizontal drainage area of water intake structure in the valley part of Dzknaget, 3.5 ha. Area planned for 1.7km long water pipeline /about 1.2 ha/, through which water from treatment structures will be supplied to Dzknaget-Sevan operating water main. The total area planned for operation is about 2.0 ha, of which 0.8ha is for water intake structures and 1.2 ha is for the pipeline. The study of the flora of the studied area was done in early September 2013 by linear-route method. Besides, the landscapes (Figure 1) and individual plant species (Figure 3, 4, 5) were photographed. It can be confidently stated that in all sites mainly the same species grow, with insignificant differences. It can be noted also that from floristic point of view the flora of the area is rich in species composition.

Figure 3: Anthemis cotula Figure 4: Cichorium intybus
Figure 5: Taraxacum officinale
During the field studies, special attention has been paid to rare and endangered plant species, as well as the species of wide application (medicinal herbs and edible plants). As a result of the studies species of plants included in the Red Book were not found in the studied area. The flora of the impact area is mainly represented by mountainous-steppe families, with predominant Festuca valesiaca, Koeleria cristata, Stipa tripsa, etc. There are also Carex hurmilis, Poa pratensis, Cichorium intybus, Anthemis cotula, Taraxacum officinale, etc. Bushes of Sorbus kuznetsovii, Rosa spinosissima, R. canina, Spiraea crenata, crataegus orientalis, Salix caprea also occur here. Taking into account the fact that the studies of the impact areas have not been made throughout the growing period, the data on the plants in the Red Book of Armenia / 2010 /, literature data and the herbarium collections of the National Academy of Sciences, Institute of Botany were taken as basis.
Specially protected nature areas “Sevan” national park is located at a quite big distance (about 15km) from the impact area.
5. ENVIRONMENTAL AND SOCIAL IMPACTS
During implementation of the project positive and negative environmental and population health impacts are possible. As a result of the works aimed at the improvement of W&W systems the expected positive population health and social effects are as follows:
Sub-project VI, Package VI.4 Environmental management plan 16 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
providing sufficient drinking water to population, providing high drinking water quality, 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, reduction of drinking water pollution hazard, prevention, exclusion of penetration of viruses of various diseases, improvement of health condition of population, increasing duration of water supply to population as a result of water loss reduction, increasing water consumption efficiency by introduction of water metering system. As a significant positive impact on the environment, protection of water resources as a result of their efficient use can be mentioned. Initial environmental examination (IEE) revealed that the implementation of works aimed at water supply system improvement in Sevan town will not have irreversible harmful effects on landscapes, flora and fauna in the works implementation area. The probable negative effects might be mainly caused by construction works implementation, and expected to do little damage and be temporal. The possible negative impacts during the construction of underflow water intakes are as follows: 1. Violation of ecosystem of the Dzknaget River, destruction of aquatic world that can be caused by: reduction of water amount in the Dzknaget river, drying of the river, violation of river bed, river pollution with household and construction waste, river pollution with lubricants and fuel. 2. Violation of landscapes in the Dzknaget River depression, destruction of habitats of flora and fauna species that can be caused by: destruction of vegetative soil layer, flooding of the area by underground waters, pollution with household and construction waste, pollution with lubricants and fuel. 3. Pollution of underground water that can be caused by: pollution of construction site with household and construction waste, pollution of construction site with lubricants and fuel. 4. Violation of water quality in underflow water intake that can be caused by: deviation from the design during the construction of drainage system (pipes and structures), incorrect construction of filtering layers, deviation from the design solutions. During the construction of water main the following adverse impacts can be expected:
Sub-project VI, Package VI.4 Environmental management plan 17 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
1. air pollution 2. noise 3. violation of landscapes adjacent the trench 4. soil erosion and soil eroding processes 5. environment and water resources pollution by construction and household waste 6. soil and water resources pollution by fuels and lubricants, 7. soil and water resources pollution by chlorine, 8. violation of river ecosystems in segment crossing the river. Since the construction works will be implemented at about 12km distance from the nearest residential area (village Tsovagyugh) and at 23km distane from Sevan town, adverse impacts on health of population in the given communities are not expected. At the same time this distance imposes that during the construction a construction site is established where the machines, storage buildings, as well as sanitary-hygienic equipment for constructors are located, which will have their negative impacts on aquatic and land eco- systems and landscapes. For all of these impacts prevention and mitigation measures are planned in the Management plan. The measures planned to prevent or mitigate the negative impacts shall be implemented by the contractor, while the implementation control will be done by the controlling and supervising authorities. The EMP and SSEMP are integral part of the environmental assessment document and are included in working drawings. Implementation of these works will have positive social effects. It will improve the population life quality in Sevan town and adjacent villages, providing sustainable and reliable water supply and water resource rational use for about 25,000 people.
6. ENVIRONMENTAL IMPACT MITIGATION MEASURES
Environmental Violation of the Dzknaget river ecosystem According to hydrogeological data the Dzknaget river flow in the place of joining with Qyoroghli tributary is 88l/sec, and downstream the construction of underflow intake structure, it becomes 64l/sec. 24l/sec water quantity is drained in the coastal sites of the river. The design plans collection of this drained water quantity in horizontal underflow intake structure and use this water for supply to Sevan town. Thus, decrease in water quantity in the Dzknaget River is not anticipated after the project implementation, since water intake is implemented at the expense of drained water quantity. Since the underflow water intake is to be constructed in valley site of the river, along the given section of the river, at 3.5m distance from the bed, during the construction works temporary disturbance of the river ecosystem and landscapes of coastal areas is possible. To prevent violation of ecosystem of the Dzknaget River in the depression area, with destruction of habitats of aquatic flora and fauna species that can be caused by destruction of vegetative soil layer and flooding of the area by underground waters, the following is planned:
Sub-project VI, Package VI.4 Environmental management plan 18 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
Implement the trench with segments not exceeding 50 to 60m in length to avoid collection of ground water under the trench bottom and collapses caused by them and to enable installation of drainage pipes. Along the working contour of the trench excavate up to 0.15m deep and 4.2m wide vegetative soil layer and transport at up to 100.0m, to the temporary landfill area. Excavate the trench in the sequence provided in the detailed design to exclude the trench collapse. The clean pebble-gravel soil excavated at deeper layers can be further used for backfilling purpose. The non-return, filtering layers around the water intake pipelines shall be implemented with a special attention and without design changes. The layers shall be fully installed only by hand. After completing the works in the given section, the vegetative soil layer shall be rehabilitated in the previous section by returning the transported soil mass.
To exclude surface and ground water pollution with construction and household waste, as well as with fuels and lubricants, the latter construction site must be established out of the area of underflow water intake construction area. Closed bins shall be installed in the construction site and the waste shall be removed from the site after completion of construction. For collection of toilet and household wastewater, metal tanks shall be installed in the site and regularly emptied and transported to corresponding places. To exclude penetration of fuels and lubricants into underground and surface waters; store fuels and lubricants in specially allotted areas on the construction site. Implement regular inspection of machines and equipment to prevent discharge of lubricants. Immediately remove the earth surfaces randomly damaged by fuels and lubricants to more safe areas. To exclude water quality infringement in the underflow water intake, the following is required: The five reverse filtering layers must be fully implemented only by hand, section by section, with the help of temporal thin boards. Back fill of pebble-gravel excavated on site on the 50cm thick reverse filtering layer.
To prevent generation of landslides, explosive works shall be excluded and preliminary loosening of rock soils shall be done mechanically. To prevent soil erosion and sediment transport, the following is to be implemented: in inclined sites of the water line route implement measures for retaining the inclinations; minimize the time during which trench and pit excavations for regulation and metering nodes are open. After completion of the construction works, all working sites shall be cleaned and brought to their preliminary shape. The damaged landscapes shall be rehabilitated, soil shall be recultivated. To exclude land and water resources pollution with chlorine, organize works for washing and disinfecting the water main with chlorine according to calculations. Provide appropriate technical means; implement chlorine discharge to surface water body after washing the pipes, according to the corresponding standards.
Sub-project VI, Package VI.4 Environmental management plan 19 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
To prevent environment pollution during construction provide spare and maintenance safety for chemicals, fuels, lubricants, explosive substances. Implement sterilization of out-of-date or extra substances (burying, removal, incineration, etc.) according to the established order. Keep fuels and lubricants in stores on areas far from the site. Install of metallic tanks for construction of temporary toilets for workers. Remove the tank from the site and transport to appropriate media after completion of the construction. Forbid incineration of household waste in the construction site. Drinking water quality change – Environmental monitoring plan must include also control over water quality and residual chlorine level. With the purpose of monitoring the quality of water entering the underflow intake, regular sampling shall be done from the last observation chamber of the underflow intake and check the water quality acording tothe RA standards. Besides, AWSC will implement also planned sampling of supplied water, checking the quality of the water of the new water source, according to all the parameters required by the Ministry of Health. Water quality monitoring is carried out also by State Hygienic and Epidemiological Surveillance Inspectorate, according to ''Drinking Water. Requirements to the Centralized Water Supply System's Water Quality''; Quality Control № 2-III-A'2-1 sanitary rules and norms'' (registered on 28.12.2002), document, which establishes the requirements to the drinking water quality, as well as the rules for quality control of water produced and supplied to residential area through water supply systems. Change in water quality in the Hrazdan River – improvement of Sevan town’s water supply will result in increase of household wastewater quantity. Wastewater from Sevan town are transmitted through wastewater system to Caghsi wastewater treatment plant and discharged into the Hrazdan River. Since Caghsi WWTP does not operate currently the household wastewater fills into the Hrazdan River without treatment and pollutes it. At first glance, the increase in the quantity of wastewater will cause further pollution of the river, but since the population number remains constant, dilution of wastewater occurs, thus additional contamination is not expected.) For mitigation or prevention of the above mentioned adverse impacts, mitigating measures are planned and environmental management plan EMP (Appendix 1), as well as site specific environmental management plan EMP (Appendix 2) were developed, which shall be followed by the contractor, controlling and supervising units.
Social To prevent hazards for workers during the construction, the following must be implemented: install fencing around construction site; control access of unauthorized persons to site; place warning signs in dangerous places; carry out regular examination of equipment by highly qualified staff, as well as make regular safety audits; provide first aid and safety training to construction staff. Provide community participation in subproject design, which will minimize disruption to community social activities.

7. INSTITUTIONAL FRAMEWORK OF ENVIRONMENTAL MANAGEMENT
The organizational obligations for the proposed mitigating measures are distributed among the following agencies:
Executive agencies, which are responsible for implementation of the measure. 1. For this special task the executive agency (HGSN Ltd and JINJ Ltd. joint venture) must provide in the design stage obtaining of all the required agreements and permits from corresponding state and local authorities, before tendering the construction works; - Conclusion of environmental expert examination (if needed); - Decision of town and village administrations related to land allotment during the construction works (if needed); - Agreement of the State Agency for Protection of Historical and Cultural Monuments, if impact is envisaged by the design. 2. The executive agencies in the construction stage (construction contractors) will be responsible for physical implementation of mitigating measures planned under the EMP and SSEMP, as well as for obtaining of all permits and agreements required during the construction implementation. Those are: - Agreements from the local self-governing authorities for the sites allotted for transportation of wastes and construction garbage, - Agreement of the State Agency for Protection of Historical and Cultural Monuments, if unexpectedly historical and cultural or archaeological monuments are discovered during the construction implementation. 3. Before commencement of the construction, the following permits and certificates must be obtained from ADB/PMU, if needed: - Cadastre certificate on the land allotment; - Water use permit, if needed.
Controlling agencies, which are responsible for controlling the executive units to provide implementation of the EMP measures by the latter
1. AWS CJSC/ADP PIU environmental specialists will be responsible for in time, due and reliable implementation of the works and measures in the order under the EMP and SSEMP. The mentioned specialists will regularly visit the construction sites to provide due implementation of the measures aimed at mitigation of work impact. During the visits the possible gaps will be identified and the infringements in implementation of mitigating measures will be discovered in accordance with the Field visits checklist (Appendix 3). The AWS CJSC/ADP PIU has the right also to require and check whether all permits are available and valid, all the measures and monitoring part under the EMP are implemented during the construction, in accordance with ADB guidelines and the RA environmental and social legislation. 2. HGSN Ltd. and JINJ Ltd. joint venture will also implement control of implementation of mitigating measures during the construction. The environmental specialist shall make visits to control the EMP and SSEMP implementation and assess the situation according to the Field visits checklist (Appendix 3).
Sub-project VI, Package VI.4 Environmental management plan 21 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
Instrumental assessment of environmental pollution will be implemented both by the Client and the Consultant according to the Emissions/ambient monitoring form (Appendix 6) and in case of revealing deviations from the standard, corrective actions will be required by the contractor.
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 monitoring agencies are as follows: - State Environmental Agency of the Ministry of Nature Protection, - State Epidemiological Agency of the Ministry of Health, - The State Agency for Protection of Historical and Cultural Monuments, if needed, - The RA local self-governance bodies, - The RA Ministry of Transport and Communication. The amounts envisaged for implementation of environmental measures included in the EMP and SSEMP 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.
8. ENVIRONMENTAL CONSULTATIONS
To represent information on the project to the beneficiary and affected public, within the framework of the sub-project of improvement of water supply system of Sevan town, public hearing was held on November 26 in town administration of Sevan town. The public hearing was held also within the framework of environmental expertise process where it is planned to represent to the interested public the Environmental Impact Assessment (EIA) report. To provide the presence of all beneficiaries, preliminary agreements were gained with the Sevan town mayor, company staff, NGOs functioning in the town and representatives of other stakeholder organizations. Besides, an announcement on the public hearing was also disseminated through the Aarhus Centers’ network and “Hayastani Hanrapetutyun” newsletter. The meeting was attended by the deputy-mayor, representatives of the town administration staff, heads of villages Semyonovka (within the administrative area of which the water intake is planned) and Tsovagyugh, representatives of local mass media, NGOs and residents (17 participants - see Figure 6). During the meetings the works planned under the detailed design were represented, after which the environmental specialist represented the possible adverse environmental impacts described in the environmental management plan.
Sub-project VI, Package VI.4 Environmental management plan 22 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
The latter is the description of the negative impacts on the environment, population health and safety of construction workers, which are possible during the sub-project implementation in design, construction and operation stages. The list of the measures mitigating or preventing these possible negative impacts was also represented. The meeting participants were mainly concerned with the following problems arising during the construction works: reduction of water in the Dzknaget river and worsening of water quality, Violation of the river banks and landscape, Pollution of the river banks with construction and household waste and presence of construction waste after completion of construction, Improper washing and disinfecting of new pipes, resulting in unclean water in flats for a long time. After representing the EMP, the environmental specialist asked the residents to get acquainted in detail with the environmental management plan and during the construction follow implementation of the measures included in the plan. A copy of the environmental management plan was left in the Sevan town administration. The Sevan town contact data are: Sevan town: Tel.: (+372 61) 2 43 23, address: 164 Nairyan street, t. Sevan E-mail: [email protected] Website: www.sevansity.am Mayor: Rudik Ghukasyan

9. GRIEVANCE MECHANISM FOR AFFECTED PUBLIC
A grievance mechanism for external stakeholders and affected public is a process focused mainly on receiving, evaluating, and addressing project-related grievances from affected communities at the level of the WSSSP. The grievance mechanism differ from other forms of dispute resolution (e.g. courts, administrative systems, etc.) in that is offers the advantage of a locally based, simplified, and mutually beneficial way to settle issues within the framework of the relationship between the WSSSP and the community.
Sub-project VI, Package VI.4 Environmental management plan 23 HGSN LTD - JINJ LTD Improvement of water supply systems in Gegharkunik region
Properly designed and implemented grievance management processes can benefit both the WSSSP and communities by increasing the likelihood of resolving minor disputes quickly, inexpensively, and fairly with solutions that reasonably satisfy both sides without taking the grievances to other (formal) dispute resolution body. Grievance mechanisms can help to identify and resolve issues before they are elevated to formal dispute resolution methods, including the courts. For a grievance mechanism to function effectively, it is important to define the grievance processing structure and to assign responsibilities for the mechanism’s implementation and make them clear for the stakeholders. Contact details for questions, complains and recommendations from the external stakeholders of the WSSSP are as follows: 1 71 – AWSC Customers Support Calling Center, Investment Programs Coordination Department Mrs. Lilit Hovhannisyan - Environmental and Social Impact Specialist 8A Vardanants Blind Alley, Yerevan 0010, Armenia Phone/Fax: (+374 10) 542877 Email: [email protected] AWS CJSC will register all complains. The Registry form is provided in Appendix 4. The focus of the grievance mechanism on the needs of affected communities is substantiated by the fact that they are directly, and in some cases significantly, affected during the project implementation but often lack viable options or capacity for raising their concerns through formal structures such as the courts. This is especially true for disadvantaged groups within communities. The WSSSP should periodically review the adequacy of the grievance process, with the participation of communities, and agree on modifications. The contact details will be provided in construction information posters and information leaflets distributed in the project affected communities during the public consultations. Questions and comments expressed during the public meetings will be recorded and addressed during the design and implementation of the WSSSP.
A grievance mechanism will be available to allow an AP appealing any disagreeable decision, practice or activity arising from disturbance during the construction works. APs during public consultation will be fully informed of their rights and of the procedures for addressing complaints whether verbally or in writing during consultation, survey, and time of compensation. This can be obtained through by ensuring full participation and consultation with the APs, and by establishing extensive communication and coordination among the affected communities, the PMU and town or community heads. The below grievance mechanism does not limit the citizen’s right to submit the case to the court of law just in the first stage of grievance process.

10. ENVIRONMENTAL MANAGEMENT PLAN
The EMP will be based on the results of IEE and SSEMP 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.
In case if an unanticipated environmental impact arises during the construction, the Table provided in Appendix 5 Unanticipated Impact / Significant Incident / Accident Notice will be filled up and attached to the varied orders. 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 and SSEMP 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 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.
