1.2. LOCATION DATA 1.2.1. Substation and OHL area 110/35 kV substation "Mosna" is going to be build on location on the east of Serbia, nearby regional road No.106 -. The nearest town is D.Milanovac approximately 8 km far away.

The length of OHL 110kV Majdanpek 2 -Mosna is about 25.0 km and the length of OHL 35V Mosna - existing Mosna (35/10kV) is about 2.2 km. of way The lines route for 110 kV and 35 kV OHL are shown in graphic addition. Right (ROW) width for OHL 110 kV is approximately 6.7m (distance between outside OHL under conductors). Right of way width for OHL 35 kV is about 3.9m. Width for cutting trees OHL have to be more then distance between outside OHL conductors and depends on trees height and conductor height. 1.2.2. Analysis of location Location for SS 110/35 kV substation "Mosna" is on south-east of the city Donji Milanovac. Nearby location pass regional road No.106 Donji Milanovac-Negotin. Occupied land for 2 of substation will be 5 000 mi. There is no industrial or residential structure near surrounding substation. the OHL 110kV for Mosna will be connected to SS Majdanpek 2 on the feeder bay No 6 in switchgear 110 kV . The fist part of line route follows existing right of way OHL No. 171 Bor 2 - Majdanpek 2. When the route approach to OHL 400kV No. 401 Drmno -Djerdap from existing turn left and follows its right of way. Near the village Blizna line route separate line, turn to left and direct to location of new substation Mosna. Line route is located so that cutting of forest should be as little as possible. SS For supply, existing SS 35/10kV Mosna it is foreseen a new OHL 35 kV from new 110/35kV Mosna. There is no industrial structure near surrounding of OHL.

Transmission lines route are shown in graphic edition 4 EPS-ELEKTROISTOK SS 110/35 kV Mosna, Design department OHL 110 kV and 35 kV 1.2.3. Quality of the environment on a planned area Location for substation 110/35 kV "Mosna" is in area of National park and is arable soil. The border of National park is about 0.6 km far from location of SS. There are no industrial structures and residential area in near surrounding. Surrounding has good ventilation, sun expose and there are no direct contaminants of ground and air. First part of route near SS Majdanpek 2 (approximately 0.6km) is located near by the edge of town of Majdanpek. This area is not residential. Remaining part of OHL route mainly pass through forest with very little pasture or meadow and arable soil. Part of line route 110 kV in front of SS Mosna (approximately 0.6 km ) is located in area of National park. OHL 35 kV for existing SS Mosna(35/lOkV ) is completely located in National park. 1.2.4. Population and concentration of people There are no residential areas around location for SS 110/35 kV "Mosna". This area, in this moment is cultivated field. Approach to substation will be by new access road. This road will use only motor vehicles for the purpose of substation. Substation will have no employees occasionally will be controlled by JP Elektrotimok Zaj ecar. There are no residential areas near by new OHL 11OkV. On the line route 11OkV the nearest houses of village Blizna is 250m far from line route. OHL 35kV is located near by residential area of Mosna (distance from nearest houses is 50.0m). 1.2.5. Reasons to select a proposed location Location of SS110/35 kV "Mosna" is on the ground received with acceptance of town planners. During choosing location, we took care of optimal using of terrain as well as possibility of easy connecting to regional road Donji Milanovac-Negotin.

Substation "Mosna" (110/35 kV) represents the supply point of the outermost east region of Serbia (Donji Milanovac region) which otherwise is not connected on 110 kV level. This situation gives rise to extremely unfavorable voltage conditions bringing about impossibility to meet the requirements of important loads because the existing network on low voltage cannot cope with the demand, meaning that this part of the country is facing supply of electricity of insufficient reliability. The improvement of supply in the region would encourage economic and business development in an area that is facing slow demographic growth rate due to slack economy.

The new substation would be supplied (during the first phase) via a direct and radial 110kV line from the supply point 2 (110 kV) being connected to the system with several lines. During the second phase, it was planned to build an overhead line leading to hydro-power station (HPS) Derdap 2 (110 kV, 200MW) meaning that Mosna substation would receive double-sided supply substantially enhancing its position in the network, and that the power supply from HPS Djerdap 2 would be directed towards the western part of the country (where the load is located), electricity generation conditions would improve leading to adequate stability of HPS operation (it would especially deal with reactive power posing some concern in the area of the HPS), the security criteria n-I (for the HPS) would be thus met enabling satisfying necessary preconditions for power withdrawal from the HPS in case

Material for grounding is round deep galvanized steel wire. 1.3.2.3. Planned production process from Basic technological process of all substations is transformation of electrical energy kV) and higher voltage level (in this case 110 kV) onto lower voltage level (in this case 35 supplying theirs connecting with existing and future substations of lower voltage level for 10 EPS-ELEKTROISTOK SS 110/35 kV Mosna, Design department OHL 110 kV and 35 kV surrounding consumer area on 35 kV voltage level.

Purpose of OHL is transmission electric energy on high voltage from one substation to another. 1.3.3. Review of a type and quantity of needed energy, water and raw materials From required quantity of energy, water and raw materials point of view, in this structure is of interest just command building which requires electrical energy for self-consumption of substation and water for sanitation system. Command building will be connected on to local water reticulation, and also it will be connected to the telephone service. During exploatation OHL does not need any kind of energy, water and raw materials. 1.3.4. Review of a type and quantity of discharged gasses, waters, other liquid and solid substances Since circuit breakers in the 110 kV switchgear is done with SF6 insulation, emission of SF6 gas in the air will be present. That emission at annual level will be less then 0,5 % from all amount of gas in equipment. It will not be other emissions in the air. Sulphur hexafluoride (chemical symbol: SF6) is a noncombustible and nontoxic gas which does not react chemically with other substances. One of the physical characteristics of SF6 is that the gas 'swallows' electrons thus neutralizing them. This makes SF6 particularly important for switchboards, switches, power lines, and transformers in medium-voltage and high-voltage engineering. The space saved when SF6 is used instead of its 'competitor' air as a protective gas to ensure insulation and to extinguish arcs - is another major advantage. In 1995 it became known that SF6 is a strong greenhouse gas. However, its quantitative contribution to global warming is below 0.1 % with respect to the other man-made greenhouse gases. Nevertheless the electrical industry considers it good environmental practice to handle SF6 with care so that its emission into the atmosphere is minimized. The International Electrotechnical Commission (IEC) covers the application of SF6 in electric power equipment with a number of standards and this project complies with them: - IEC 60376 Specification and acceptance of new sulphur hexafluoride, - IEC 60480 Guide to the checking of sulphur hexafluoride (SF6) taken from electrical equipment. - IEC 61634 High-voltage switchgear and controlgear - Use and handling of sulphur hexafluoride (SF6) in high-voltage switchgear and controlgear.

In regular regime of work substation, because nature of technological process, does not discharge any substances in the water. Substation will be connected to the sewerage reticulation. Because nature of technological process, there is just disposal of communal waste which will be disposed in accordance with The Law on Handling Waste Materials (Official Herald of Republic of Serbia No.25/96),

Used transformers oil is a specific kind of waste. That oil collects in specific way and purifies (filtrates) in other to use again, in another words transformers oil recycles. Filters for purification will be disposed accordant with Waste Disposal Law (Official Herald of Republic of Serbia No.25/96) and Rulebook on managing with Hazardous Materials (Official Herald of Republic of Serbia No. 12/95). OHL is a kind of facility that does not discharge gasses, waters, other liquid and solid 11 kV Mosna, EPS-ELEKTROISTOK SS 110/35 and 35 kV Design department OHL 110 kV substances in surrounding area. 1.3.5. Review of environmental impact assessment of a proposed technology Proposed technology for substation and OHL represents modem solution that follows world's standards and norms. With this technology, environmental protection is included. 1.4. POSSIBLE CHANGES AND ENVIRONMENT IMPACTS 1.4.1. The Change of Air Quality During the performance of activities related to the construction of substation and on OHL, there will be changes in air quality, due to the utilization of construction machinery. Having in mind that these activities will last for a very short period, together with the utilization of small number of construction machinery, changes in air quality will only be temporary. Utilization of SF6 gas as the insulation device within the equipment (circuit breakers), during the regular operation of the substation, may causes the emission of this gas into the air, this being the consequence of equipment imperfections. This possible emission would annually in amount to less then. 0.5% of the total gas quantity present in the equipment. The change air quality may arise as the effect of this, and it is going to be of local and temporary character, since SF6 gas is not dangerous for living organisms, but it belongs to the group of green house gases.

During the operation OHL 110 and 35 kV voltage level there is no change in air quality.

1.4.2. Change of water quality Underground waters or permanent level of underground water were not discovered, therefore the construction of substation will not have an impact on water quality. During the regular operation, the substation will not have an impact to water quality since it will be connected to the sewage network. If the outflow of transformer oil should happen in the case of an incident on power transformers, through oil tube oil will be collect in oil pit. Common oil tub will be made of armored concrete, water resistant, or iron tank proper volume can be used also. During the operation OHL 110 and 35 kV voltages level there is no change in water quality. 1.4.3. Change of soil quality During the construction of substation and OHL, in the course of excavation activities by means of construction machinery, temporary degradation of the soil will be performed, in other words temporary change of soil quality will occur. Ground used for the construction of the plateau for the 110 kV facilities is leveled, and stabile in natural conditions. Performance of anticipated activities will not endanger its stability. During the regular operation, the substation will not have an impact on soil quality since it will be connected to sewage network and the only waste emerging during the normal operation will be municipal waste. Transmission lines during construction and operation do not influence to soil quality. 1.4.4. Change of Noise Level During the construction of substation, noise above permitted limits will occur due to

12 EPS-ELEKTROISTOK SS 110/35 kV Mosna, Design department OHL 110 kV and 35 kV utilization of construction machinery. During the regular operation of the substation, noise will be created by power transformers, as well as their cooling fans and it will be according to NEMA TR 1 standard which is provided by manufacturer.

According to JUS U.J6. 205/1992 standard Acoustic Zoning of Space, surrounding of SS is classified in the group of small and village settlements with the highest permitted noise level of 50 dB for day and 45 dB for night. 45 meters from the fence, calculated values of noise would be 25.88 dB for the day < 50 dB, and 22.16 dB for the night < 45 dB so substation during regular operation will not create noise above permitted limits. During the operation OHL 110 and 35 kV voltages level there will be no noise effect. 1.4.5. Change of ionizing and unionizing radiation During the construction of substation and OHL no ionizing radiation sources will be used. During the regular operation of the substation and OHL there will not be any ionizing radiation, because according to the nature of the technological process, there will not be any sources of ionizing radiation. According to the nature of the technological process, during regular operation, there are electrical and magnetic fields as the form of unionizing radiation, created by overhead conductors, and they depend on voltage level, current intensity and distance. Serbia doesn't have a Law on non-ionizing radiation but applies all IRPA standards (International Radiation Protection Association ) and based on the criteria of the World Health Organization (WHO), permitted intensity of electrical field amounts 5kVeff/m, and the permitted intensity of magnetic field amounts to 100,T. From empirical data obtained through the utilization of Field program for substations similar or the same as the substation which is the subject of this study, it can be concluded that values obtained for electrical and magnetic fields are many times lower from the values prescribed by the WHO. Value of electrical field is around four times lower than the prescribed value, while the value of magnetic field is around nine times lower from the prescribed value.

There is no ionizing radiation during operation of OHL. 1.4.6. Impact on people's health Construction of substation will have an impact on people's health in terms of increase of noise level above permitted limits, primarily due to the utilization of construction machinery. Because these construction activities will only last for a short time, this impact is of temporary character.

Based on empirical data obtained for the same or similar substations it can be concluded that intensity of electrical and magnetic fields of SS 110/35 kV Mosna are negligibly low, i.e. much under the values prescribed by WHO. Since the noise level created by the transformer during night and day operations does not exceed the permitted intensity special measures for noise reduction will not be taken. For OHL voltage level 110kV and 35 kV values for electrical and magnetic fields are many times lower than the limited. Line route of OHL 110kV Majdanpek 2 - Mosna is chosen not to be near residential area and impact to people's health is reduced to minimum. 13 SS 110/35 kV Mosna, EPS-ELEKTROISTOK OHL 110 kV and 35 kV Design department 1.4.7. Change of climatic conditions There will be no impact on climatic changes during construction and operation of substation and OHL. 1.4.8. Change of ecosystem At the substation site, as well as in its environment there is protected ecosystem (National the park Derdap). Flora and Fauna will be changed only within the fence of the SS and within OHL right of way. These changes are negligible in relating to ecosystem of National park. 1.4.9. Change of population, concentration and migration of population an Activities related to the construction and operation of substation and OHL will not have impact on the population, concentration and migration of population. 1.4.10. Change of land use Construction of substation will change the use of land only within the fence of substation. Surrounding land will not change the purpose. to be Under ROW (right of way for OHL) safety distance between conductor and trees have kept and because of that, marked high trees have to be cut. Safety distance between conductor (110 kV and 35 kV) and trees is minimum 3.0m. 1.4.11. Change in municipal infrastructure and Construction of the new substation and OHL increase material goods in this area In simultaneously provides better possibilities for their further growth and development. addition to the importance in relation to growth of material goods at the local level this the expansion is of great importance to better, safer and more economical operation of surrounding part of the power system of Serbia. 1.4.12. Change in protected natural and cultural assets 2 for In area of National park necessary land for expropriation will be about 5 000 m 2 substation and necessary land for expropriation will be about 150 m for OHL towers.

1.5. SUMMARY OF MEASURES TO BE TAKEN 1.5.1. Measures anticipated by the law and other regulations, norms and standards Detailed design and other technical documents will be used to plan the measures anticipated in regulations in force, JUS standards and technical recommendations of EPS, related to: protection on - safety distances ( Distances defined by Rulebook of general measures work from dangerous effects of electrical current . Article 38. says that the shortest safety distance from parts under voltage between 35kV and 135kV is 2000mm ). to decrease probability of - insulation coordination ( Point of insulation coordination is insulation damaging caused by overvoltage tenses to economic acceptable level) currents for - selection of the equipment in compliance with the expected short-circuit thefuture period of at least 10 years, selective activity of protection devices ( According to TP4b), their installation on all - selection of sensitive protection and automatic devices and the elements of the facility for the purpose quicker and safer disconnection of the part of 14 EPS-ELEKTROISTOK SS 110/35 kV Mosna, Design department OHL 110 kV and 35 kV facility where the fault occurred, - permanent monitoring of changes in measuring values and alarm states, periodical inspection of facilities and corresponding measurements (thermovision,investigation of insulation oil, visual inspection, etc.) - training and inspection of staff training. Transport of transformers will be performed along the route planned in advance, with previous obtaining of necessary compliances and undertaking of measures for the security of transport. Transport of oil will be performed separately in 200 1 barrels, in trucks with the corresponding transport protection measures. Loading and unloading of transformers will be performed together with low manual hydraulically jacks. After the installation of transformers onto the foundations and the bund, unloading of oil and filling of the transformers will be performed by means of electrical pumps from the barrels on the trucks directly into the transformer tank. Hoses used to unload oil and the system used for the connection of hoses, in the places anticipated for this use at the transformer boiler, is performed in a way which makes impossible the spilling of oil. Two internal roads 3m and 5m wide will be constructed within the facility for the transport of equipment and machinery access, as well as concrete footwalks for the access of staff to the certain parts of HV equipment. They will enable quick and easy access to the equipment in all cases. 1.5.2. Measures to be taken in the case of an accident Detailed design and other technical documents will be used to plan the measures that need to be taken in the case of an incident: Separate fire protection report will be elaborated in a way to exclude fire that could endanger environment and people's health in the surrounding settlements. Foundation engineering of transformers is performed on separate foundations autonomously. Through the application of fire protection measures the possibility of fire occurring outside the substation is eliminated. Measures were taken to prevent the spilling of transformer oil, i.e. its spreading around the transformer, in that the bunds filled with gravel were constructed below the transformer and connected by ducts with the leak-proof pit for the collection of spilled oil,. In the case of oil spill, oil pit is sufficient to accept the complete amount of transformer oil. If the spilled oil takes fire, gravel filter prevents the spreading of fire, and the extinguished oil penetrates to the bottom of the bund. Fire on transformers is practically ruled out due to the application of contemporary protection devices.

Transmission line will be automatically disconnected due to the application of contemporary protection devices in a case of the fault (on conductors, insulators etc.). 1.5.3. Plans and technical solutions for environment protection According to the nature of the technological process, the substation in regular operation does not produce waste material, i.e. it does not endanger the environment. Application of the protection measures will prevent the negative environment impact even in the case of an incident. Used transformer oil is recycled, i.e. treated by means of special filters in order to be used again. Disposal of used filters will be performed in compliance with the Law of Treatment of Waste Substances (Official Gazette RS No 25/96) and the Rulebook on the Manner of Waste Treatment Having Qualities of Hazardous Substances (Official Gazette RS No 12/95).
