BACKGROUND Additional Financing for Electricity Supply Reliability Project (ESRP AF), requested by the Government of Armenia, intends to increase the reliability and capacity of the transmission network through rehabilitation/replacement of key transmission assets. To achieve this objective, the ESRP AF would include complete rehabilitation of Charentsavan-3 substation (SS) of High Voltage Electric Networks CJSC (HVEN). This SS was originally established as a 220/110 kV substation in 1985. The Charentsavan-3 SS is now used as a 110/10 kV SS and its main role is a switching station for surrounding 110 kV distribution substations after the 220 kV overhead transmission line (OTL) from Hrazdan TPP was dismantled. No major rehabilitation has been conducted since its commissioning. Poor equipment condition sometimes caused unnecessary outage not only to its own distribution customers, but also to other connected substations. Thus, given the obsolete condition of Charentsavan-3 SS and the wide-area outage threat because of eight OTLs from this SS, complete rehabilitation of substation is needed to ensure reliable power supply in Charentsavan town and surrounding area. As part of the preparatory work for rehabilitation of Charentsavan-3 SS, an Environmental Management Plan (EMP) is required. 2. PROJECT DESCRIPTION Location and Site description The Charentsavan-3 SS is located in the north-east of the city of Charentsavan. The Charentsavan city is located in Kotayk marz (region) in north-western part of Armenia. The city is situated on the left bank of Hrazdan River at the altitudes ranging from 1,600 m to 1,700 m above sea level. The region has moderate climate; the average temperature in July is 17.7օ C, and the absolute maximum temperature is 35օ C. The average temperature in January is -6.2օ C, and the absolute minimum temperature is -23օ C. The average annual temperature is 6.4օ C; average annual relative humidity is 71%; average annual precipitation is 666 mm. Charentsavan area has poor vegetation cover. Being located in a developed area, there is no wildlife within the project area. The SS site has flat topography and is surrounded by wheat fields to the north and north-east and by raspberry plantation to the south-east; these cultivated lands are private. There are hayfield to the north-west and apple, apricot and cherry trees as well as small haricot plantation to the west, south-west and south of SS, cultivated on public lands; land use is unregistered. All crops are grown by the residents of neighboring communities for personal use. The closest residential area is about 1 km. There is a small water stream in 7 m distance from the fencing of the SS to the south-east. 3 ENVIRONMENTAL MANAGEMENT PLAN CHARENTSAVAN-3 SUBSTATION The public road near the SS entrance will be used to access the site from the north-east during construction activities. There are access roads around SS fencing except from southern, south-eastern and south-western sides which are occupied by the above mentioned plantations. In case the SS must be accessed by construction vehicles and machinery from the south, south-east or south-west, some of the cultivated private land plots may be crossed causing possible damage to crops and trees or reducing access to the land or other assets. Similarly, while all construction machinery and equipment is intended to be stored within the fencing area of the SS, in case it is necessary to store such equipment on neighboring private lands, some damage or limited access to assets could results. If either case is probable, then the closed joint stock company High Voltage Electric Networks (HVEN) will develop an abbreviated Resettlement Action Plan which complies with the provisions of the project Resettlement Policy Framework, and will clear it with the World Bank, disclose, discuss with project affected people, provide compensation to the affected people, and furnish a report on the implementation of the RAP to the World Bank prior to construction commencing. However, every possible effort will be made by the contractor to avoid such resettlement impacts. The SS occupies the fenced area of 4.6 ha with various buildings having the following external dimensions (L×W): Control and dispatching building (including offices and battery room): 43 m×13 m; 10 kV feeder bus sections and two associated buildings: 37×10 m and 7×7 m each. This SS has eight 110kV OTLs and two 110/10 kV – 25 MVA transformers. One of the transformers is out of service since mid-1990s. Project scope of work The rehabilitation and expansion of the substation will involve the following: complete replacement of 110 kV Open Switch Yard (OSY) ; replacement of two 110 kV Main Transformers (MTRs); replacement of 10 kV cubicles and the associated building; installation of SCADA system and replacement of protection relay equipment; construction of a new building for control and dispatching center; replacement of Alternating Current and Direct Current (AC/DC) systems, including distribution system, chargers, invertors, and batteries; construction of checkpoint; 4 ENVIRONMENTAL MANAGEMENT PLAN CHARENTSAVAN-3 SUBSTATION reconstruction of grounding system; reconstruction of oil spill collection system; construction and reconstruction of roads and walkways; rebuilding of cable trenches; installation of fire alarm and rehabilitation of fire localization system; rehabilitation of fencing; reconstruction of external water drainage and sewerage system; and restoration of outdoor lighting. All of these activities will take place in the area of an already existing SS (as shown in Figure 1) and all impacts will be confined to the existing SS yard. Figure 1: Site Plan 3. LEGISLATION The following Armenian legislation defines a legal framework applicable to project activities: Law on Atmospheric Air Protection of RoA (1994) 5 ENVIRONMENTAL MANAGEMENT PLAN CHARENTSAVAN-3 SUBSTATION The purpose of Law on Atmospheric Air Protection is to define main principles of the RoA, directed to provision of purity of atmospheric air and improvement of air quality, prevention and mitigation of the chemical, physical, biological and other impacts on air quality and regulation of public relation. According to this law, contractor shall undertake demolition and construction activities as well as transportation and temporary storage of wastes the way to minimize dust and other emissions to the air. Law on Waste of RoA (2004) The law provides the legal and economic basis for collection, transportation, disposal, treatment, re-use of wastes as well as prevention of negative impacts of waste on natural resources, human life and health. The law defines the roles and responsibilities of the state authorized bodies as well as of waste generator organizations in waste management operations. According to this law, the waste generated by the demolition, construction, dismantling and installation activities should be recycled as appropriate, or disposed of in designated locations. Law on Environmental Impact Assessment of RoA (1995) The law defines type of activities which are subject to environmental impact assessment and ecological expertise. According to this law, works planned at Charentsavan-3 SS are not subject to the ecological expertise. Law on Urban Development of RoA (1998) According to this law, works planned at Charentsavan-3 SS require obtaining of the construction permit. 4. PUBLIC CONSULTATIONS The neighboring communities of Charentsavan-3 SS are considered to be the affected parties during the construction and operational phases. The EMP will be disclosed on the website of the HVEN and opened for public feedback. Brief information on the planned works and contact information for addressing questions and grievance will be placed at the work site and/or in its immediate surroundings/municipality. 6 ENVIRONMENTAL MANAGEMENT PLAN CHARENTSAVAN-3 SUBSTATION 5.
