Introduction:

Visegrad town is situated in the wide valley of the Drina River at the hillsides slowely raising into mountains high over 1,000 m a.s.l.

The town lake iteself is located at 364 m a.s.l., precisely at 19 0 18" E and 43 0 47 "N. Summers are short and warm with temeperature up to + 38.2 °C

while winters are long with minimum temeperature down to - 1 8.2 0C.

Two kilometers far from the town, there is the mouth of the Rzav River with large quantity of watre during the winter period. Two kilometers upstream

from the town, there is the HPP Visegrad dam. The most important cultural and historical monument is the Bridge on the Drina which is located neraby

the town lake.The town itsel has 6,000 inhabitants, while the municipality Visegrad has 23,000 inhabitants. Besides they are employed at the state companies, such as

the HPP Visegrad, Telecom, Post Officies of the Republic of Srpska, Distribution Working Unit - Visegrad, the Forests of the Republic of Srpska, the

inhabitants are mainly occupied with usage of forests through the private sawmills. Except all these, they have developed agricultural activities (raspberry

growing, extensive fruit growing, cattle raising - sheep and cattle). There are six private fish farms upstream from the HPP Visegrad dam, engaged in

production of californian and stream trout.Regarding road communication, the most important is a road direction from the inland to the Adriatic Sea - the Highway. Other communications are

weakly developed (in direction to Rogatica and Priboj).

1. Water Leakage under the HPP Visegrad Dam Body

The first measurements of water leakage on the spring were performed by the divers 1991, under water, with water speed measuring wing. It was measured about 1.4

m3/s. Concerning applied method and difficult conditions of under water measurement, this data should be considered with certain reservation.


The first exact measurements were done with water speed measuring wing 1996. Having stopped the operation of the HPP Visegrad and lowering the level of thedownstream HPP Bajina Basta reservoir, there were made conditions that only water springing from the Drina riverbed flew downstream from the dam. Themeasurement was done on three previously determined hydrologic profiles. The quantity of the leakage water was 6.5 m3 /s. In the period from 1996 to 2004 there were6 measurements in total, and the results are given in the Table 1.

reasons, power loss (40 GWh per year) and dam stability. It has been attempted to make solution for rehabilitation since 1996, but there were not any concrete results.On the basis of the previous investigations of these appearances, measurements, monitoring and analysis of so far performed works and trend of leakage quantity, whileprojecting and performing the rehabilitation works, it is necessary to meet the following conditions:

- Because of the time duration of the rehabilitation and possible unwanted appearances at the brim of the reservoir, the rehabilitation needs to be projected andperformed under the maximum water level with some oscillations caused by the normal operation of the hydro power plant (maximum to 5 m);

- Rehabilitation should not endanger the normal operation of the hydro power plant;- Rehabilitation should not jeopardize the functionality of any system, especially the drainage, as well as stability of the facility;- Rehabilitation has to be carried out with stable grouting mass and materials.

Note:

Our existing plants do not have oils containg PCBs, and the Tender Document will strictly state that the equipment to be purchased shall not contain the oils with PCBs.

2. The Reconstruction of GIS

Switchgear of 400 kV was constructed in SF6 technique with two TL bays. The supplier was RAOP - B&H. The switchgear is in operation since 1989 and has suffereda couple of heavy damages which were reclaimed within 3 - 30 days. Because of multiple heavy damages on current and voltage transforners of GIS during the periodof operation the study "The assessment of GIS in HPP Visegrad" was prepared by electro technical faculty from Belgrade. The new transformers would be with betterperformances regarding voltage strains. The authors consider that increasing of withstanding voltages would eliminate the major problems.

3. The Solution of Regulation Oil Oxidation on all Three TurbinesTo solve the problem of oil oxidation and to reduce auxiliary consumption, oil system with smaller pump of 22 kW, along with accompanying accessories (valves,pipes) and supply cabinet should be installed.

POWER IV - EPMP HPP Visegrad Pa2e 5 of 9

The scope of delivery is three identical hydraulic systems in order to reconstruct existing turbine regulation. Main objective is to install smaller pump in the functioning

existing regulation system (the pump with smaller flow), to reduce the oil quantity flowing through relieving block during 200 kW pumps idle running for

supplementing of oil - air tank.

4. Monitoring for Three Generating Sets (Vibration, Partial Discharges, Temperature Measurement)

With the objective to assess the reliability of generating sets operation and monitor equipment conditions in HPP, it was proposed to introduce, on generators and other

HV equipment, monitoring of generating set by vibration measurements, partial discharge monitoring, thermo-vision monitoring etc., which were successfully

implemented in other HPPs.

E. CONSULTATION WITH LOCAL NON-GOVERNMENTAL ORGANIZATION AND PROJECT-ENDANGERED GROUPS

The public announcement on the impact of rehabilitation works at the HPP Visegrad on the environment was published in the newspaper "Glas Srpske", through radiostation "Visegrad", as well as by distribution of leaflets to the inhabitants in order that they could participate in public discussion as one of interested parties. The publicdiscussion was opened by Mr. Milutin Baranac, with assistance of Mr. Mirko Ostojic and other expert colleagues from the HPP, on 7th February 2006 in the premises ofthe HPP Visegrad at 9:00 hrs, under following agenda:

1. The impact of rehabilitation works at some parts of the HPP Visegrad on the environment.

The explanation along with description of all envisaged works under the project was given to the attendees by Mr. Milutin Baranac, executive manager of technicalaffairs at the HPP Visegrad. The discussion participants agreed that the project components under no. 2, 3 and 4 would not have essentially negative or almost noneimpact on the environment. The exception was noted only in the project component no. 1, which is water leakage under the HPP Visegrad dam body. Namely, bycompletion of this project it would be created much better conditions in the water flow than they were now, when the flow under the dam was approximately 12.00m3 /s. However, there would be some negative impacts during the realization phase when it comes to rinsing of grouting mass. The engineer, Mr. Ostojic, explained thatthere were certain realization methods predicting sufficiently good protection measures which could enable that the downstream part of the water flow should not be

polluted.The questions and details about this project also induced wider discussion of the attendees from the standpoint of possible impacts on the Old Bridge in Visegrad town,which would be revitalized in entire downstream water flow surrounding as well.Relating to this, it should be taken into consideration that just downstream from the power plant there is the reservoir of the HPP Bajina Basta, with capacity of 280million in3 , which is situated exactly in Visegrad town. The discussion was finished at 10:55 hours.Conclusion of the discussion: Besides they showed great caution, the attendees agreed that the predicted protection measurements could offer enough safety and that

the project would be realized without harmful impact on the environment.

ENVIRONMENTAL PROTECTION MANAGEMENT PLANAT THE HPP BOCAC

2006-02-20


Introduction:

The hydro power plant Bocac is situated immediately nearby inhabited village Bocac, at the place where the Vrbas River comes out from the canyon and makes a wider

valley in which the village itself is located. At this area, the Vrbas River is a border between the municipalities Mrkonjic Grad (left coast) and Banjaluka (right coast). The

height above sea level of the Bocac village is approximately 230 m a.s.l.The climate is moderate continental, with especially expressive regional microclimate features characterized with exceptionally mild winters in comparison to surrounding

areas, and warm summers, as well as distinct spring and autumn periods.At the village area, besides the Vrbas River, there is no larger overground water flows.The average monthly temperatures in the period 2001 - 2002 (measured at 13.00 hours) for the area surrounding the HPP Bocac are as it follows in the table below:

downstream from the HPP and its role is to control the

Vrbas river flow downstream from the HPP.

Mrkonjic Grad is inhabited with 19,000 people. It is located 64 km in the South from Banjaluka and 25 km in the West from Jajce.

At this area, besides old middle-century town Bocac, located immediately above Bocac reservoir, there is no other cultural monuments.

Regarding configuration of this terrain (mountain relief), the population is mainly occupied with extensive agriculture (fruit and vegetable growing) and catle breeding

(poultry raising, sheep raising and cattle raising). Active, working population is employed partly at the HPP Bocac, the bauxite mine by Bjelajce village, then at prive fish

farm located immediately before the mouth of the Cma Rijeka into the Vrbas River, as well as existing primary schools, stores, restaurants and bars. The area is migration

one, because some of its inhabitants are employed or go to the secondary schools in Banjaluka or Mrkonjic Grad.

1. The Construction of Additional Lateral Spillway with the Tunnel in the Left Embankment of HPP Bocac Dam

Comprehensive hydrological investigations and calculations of floodwaters, emerging once in 1,000 years, made within "Actualization and updating of

conceptual design of the HPP Krupa had indicated that calculated flood waters at the HPP Krupa dam profile as well as at the HPP Bocac dam profile are

much higher than that used for the design and construction of the HPP Bocac. According to recent calculations the flow of flood water at the HPP Bocac

dam profile amounts to 2,073 m3 /s, while existing spillway is sized on 1,490 m3/s.

Taking into account above it was found that the issue of the safe evacuation of flood waters at the HPP Bocac dam profile is highly sensitive and urgent.

With additional tunnel, the HPP Bocac would be flood waters proof. The additional tunnel would be in function whenever the reservoir water level exceeds

max. water

level of 283.00 a.s.l.


Our existing plants do not have oils containg PCBs, and the Tender Document will strictly state that the equipment to be purchased shall not contain the oils

with PCBs.

2. The reconstruction of 110 kV switchgear

110 kV switchgear HPP Bocac was commissioned at the same time as HPP, 23 years ago, and the majority of its components haven't been replaced until

today. Certain equipment is close to the end of lifetime which significantly influence (reduce) the operation reliability.The most critical elements are:

- TL oil circuit breakers- Current measuring transformers- Surge arresters

TL oil circuit breakers, type HPGE I lA/15, were manufactured by Energoinvest in 1979 and have had a great number of manipulations, as well as great

number of TL shutdowns due to breaking of fault breaking currents exceeding rated values. Critical issues are also maintenance, spare parts supply andtlw,Titi o,f was 'l. tIl F-- L i i 1 i Ahth .. iodrit S-F0 GDBi, zfthz typc already installed in ge ntrMorm r L2,

Current measuring (oil) transformers, type TPE I IB, are also manufactured by Energoinvest, originally installed. Gas chromatography of oil has been

performed as well as the measuring of dielectrical losses tangent. The results were unsatisfactory (the oils used at the HPP Bocac do not contain PCBs) and

indicate the need for urgent reconstruction thr replacement of existing transformers with technologically more perfect and reliable ("invert") construction is

proposed.Surge arresters are mostly Minels arresters VOP 6E dating from 1978. The age and great number of manipulations caused by atmospheric discharges are the

reasons for the procurement of new surge arresters. This is supported by the explosion of surge arrester in 8th phase of HPP Bocac - SS Banja Luka 1 (5) TL,

mid - May 2005. It is proposed to procure new, more modem surge arresters (more strict requirements, silicon insulator, much less weight,...).

3. UPS, excitation systems for both generators, turbine regulation for both generating sets

3.1 UPSUPS for DC supply consists of rectifiers and, associated batteries. DC voltages 220V and 48V are being used for the supply of control, signalling and

auxilliary circuits.Since the system is permanently in operation, the components of inverter and all five rectifiers are exposed to heating leading to the changes of

characteristics and ageing of individual components of control part and as a consequence to unstable operation of UPS having adverse impact on

acubatteries. The overhaul (repair) of existing equipment is irrationale and very expensive. The proposal is to replace existing equipment, being in operation

for 23 years, with the new, technologically improved, equipment.

3.2 The replacement of generators (GI and G2) excitation system

Excitation system in used for the supply of generator excitation coil (generator type S 7770-40, 65 MVA capacity). HPP <<Bo-ac>> is equipped with static

excitation system with tiristor outlet part, automatic voltage regulator and current regulator (backup regulator). The manufacturer was "Rade Koncar". This

system is in operation since 1981.


Because of increased use of microprocessing components suppressing analogue technology, it was decided that existing static excitation system should bereplaced with the new digital excitation system. Since excitation system represents significant link in hydropower facilities the old system should be replacedwith modem one in time.

3.3 The replacement of electronic regulator (governor)

HPP Bocac has two Francis type turbines, with rated capacity 59.96 MW, rated flow of 120 m3/s and rated 150 rpm. Turbines governing (regulation) is donethrough electro-hydraulic governor, Hydrotrol 4 manufactured by BBC Brown Boveri. Said governor consists of electronic and hydraulic regulator.The maintenance of such unit is extremely expensive. The modules, manufactured twenty some years ago are hard to find and are relatively expensive.These modules, if found, are already twenty some years old and regardless the fact of never been used their functionality should be thoroughly checkedbefore the installation, and the reliability is far from that in the time of manufacture.

It can be concluded that further exploitation and maintenance of this unit is economically unjustified. Adding to that flexibility and possibilities gained bythe installation of new modern governor (no offsets, resistance to disturbance, simpler and more reliable connection with dispatching center, etc.) it can beconcluded that the replacement of existing governor with the new digital governor is justified investment.

3.4 The replacement of generating set cooling system

Cooling water system has been in operation since HPP commissioning and has been neither reconstructed nor replaced.

Taking into account exploitation time, the pipeline of cooling system is being damaged due to corrosion and water leakage and key components are beingdamaged also (manually and electric motor driven valves, pressure reducing valves, measuring equipment, etc.). The leakage has been rehabilitated bywelding, but since whole pipeline is constructed from same material and is subject to same operation conditions, the further leakages could be expected,which will be more difficult to mend in time.

Unreliable generator and turbine cooling system is limiting factor for generating set functioning as well as for electricity generation.

Mr. Zdravko Milic, technical director of the HPP Bocac, initialed the public discussion. He briefly introduced the project components to the attendees, as

well as its possible negative impacts on the environment during the project realization and subsequent plants operation. The attendees unanimously agreedthat three project components (items 2, 3 and 4) would not have harmful impact on the environment, but they asked for detailed explanation of the problemsrelated to the component under no 1, namely the construction of additional lateral spillway with the tunnel in the left embankment of the HPP Bocac dam.

Almost same questions were asked by the representatives of farmers, fishermen, beekeepers, etc. The main question was how the construction of above

mentioned tunnel would affect possible floods. Everybody expressed their great concems. The representatives of the HPP Bocac answered that the tunnel

should be constructed just because of easier regulation of the large waters flow and prevention of possible floods. The second question was related to the fish

life, namely if the tunnel construction would disturb already stabilized course of fish life in the reservoir of the HPP Bocac and downstream flow of theVrbas River. The explanation was given by Mr. Rudi6 Simo, professor of biology. He explained that the canal would rarely be activated, only in

emergencies, maybe once in ten years, and that there should not be worry about fish life. The other questions were technical and not related to the

environment protection. The discussion finished at 12:15 hours.

1. Introduction

Short description: Trebinje town is situated in the valley of the Trebisnjica River, in the environment of South Herzegovinian karst at the narrow zonedividing the area of karstic lakes of the Adriatic Sea.Trebinje is 274 m above sea level (a.s.l.) at 420 42" north geographic latitude and 180 20" east geographic longitude. The area of Trebinjemunicipality covers 904 km2 with 36,000 inhabitants. The climate is mediterranean characterized with mild winters and long warm summers.Average monthly temeperatures and precipitations in the period 1998 - 2005 were as it follows:

Besides they are employed at the state companies such as HET, IAT, ERS, the inhabitants are mainly occupied with agricultural production. Due toinfluence of mediterranean climate, the mostly represented is wine growing, as well as fruit growing, and, to some smaller extent, cattle raising. Inrecent time, there is a increase of number of the private fish farms where people breed stream and californian trout. The Gorica dam is 3 km far fromthe town, and there is no larger settlement around the reservoir. Downstream from the Gorica dam, at the distance of 7 km, there is old lake Trebinjawith cultural and historical monuments. The most significant monument is Tvrdos Monastery, which is 15 km far from the dam.The road communications are not too developed, and there are: Dubrovnik - 30 km towards the South, Mostar - 100 km towards the West, Niksic -70 km towards the East, and Gacko and Foca - approximately 130 km towards the North.

Downstream row- total length of drilling 596,3 m- total length of injecting 471,5 m- 108.098,5 kg of dry substance spent for injecting- average consumption 230 kg/m

Total injected length of the left bank side is 876 m with 365.190 kg of dry substance spent, average consumption reads 416,88 kg/m.At <Gorica>> division profile leakage waters have been progressively increasing since the period of Dam construction to nowadays. The investigations have confirmed the existenceof water leaking parts in Dam profile as well as on bank sides. To ensure the stability of the facility it is necessary to perform reclamation works to complete further leakage.

2. The installation of pipe generating set 1.1 MW

According to water utility permits, at the <<Gorica>> division profile, certain water quantities are being released, remaining unused from the point of view of powergeneration, taking into account the technical characteristics of existing generation set. Performed analyses suggest economically justified need to construct new seton existing one shutter outlet, which would energetically use the biological minimum water. The set should be of Pi=1. 1 MW installed capacity.The reclamation works would prevent the leakage of water (4 m3 /s) from accumulation, which could be used at HPP Trebinje II or HPP Dubrovnik.It is planned that biological minimum water, flowing through Trebinje, could be energetically used on new generation set, in the amount of approx. 6m3/s, onaverage drop of 15.3 m, in the period of six months, which represents 3.2 GWh in power. The remaining six months approx. 4m3 /s could be used on HPPDubrovnik, representing 45.14 GWh in power.It is estimated that the cost of the works on the reduction of leaking waters and the installation of new generation set could be economically compensated in lessthan three years, upon completion of all works.

ENVIRONME AL PROTECTION MANAGEMENT PLANAT THE MINE D THERMAL POWER PLANT UGLJEVIK

2006-01-17

1. RECONSTRUCTION OF THE WASTE WATER PLANT

The M&TPP Ugljevik (300 MW) is located on the slopes of Majevica mountain in agricultural-orchard region. Thepopulation live nearby the M&TPP (1-2 km), and the most inhabited place with 5,000 residents is Ugljevik (in distance ofapprox. 3 km). Waste waters at the M&TPP are discharged into the Janja and Mezgraja Rivers, whose waters are used toirrigate orchards and crops, as well as to water livestock.

There are industrial and sanitary waters at the M&TPP. All industrial waste waters originating at the TPP location arecollected by piping system, and transported and treated at the plants for waste waters treatment which is designed for twoblocks of 300 MW.The central plants for technological waste water treatment is designed and constructed of separated lines for treatment ofsome types of waste waters, but it makes complex structure with number of common elements regarding location anddesign. The waste water treatment plant consists of:

- devices for oiled and crude oiled waters,- pump stations- control room,- retention reservoirs,- re-circulation pools for receiving the scraper' water,- mud sedimentation site with plants for adjustment pH value of cleared up of the water above mud.

The sanitary waters at the M&TPP are refined biologically in special plants.

However, the scraper water enriched with particulate matters of ash, coal and high contest of sulfides is inadequatelytreated which causes quick filling of re-circulating reservoir with mud (5,5m3/day) that is ejected and transported to thedisposal site. All this creates permanent enormous fouling of waste water plants surrounding. Due to wom-out equipment,it is also impossible to do neutralization of the water above mud at the mud sedimentation site; separation of oil from themine waste waters is poor, and sanitary waters have inadequate treatment.All above mentioned causes that the M&TPP is not able to discharge the waste waters of satisfying quality into rivers.These are the reasons why there is an intention to reconstruct the waste water plant and to establish the waste water qualitycontrol monitoring at all discharge pints.The waste water plant reconstruction should include the scraper waters into re-circulation process toward scraper, thenautomatically do neutralization of waste waters from the chemical water treatment plants and waters above carbonatedmuds2, separate the grease of the mine industrial waters, and do cleaning of sanitary waters at the M&TPP.

Establishment of monitoring would control quality at all discharge points.

Installation of the piezometers at the ash disposal site, near central plants for waste waters treatment, at the building forchemical water treatment and plants for ash and slag transportation preparation would enable tracking of regime and qualityof underground waters, which has not been done so far.

1. The scraper is the part of the boiler used for collection and transportation of slag. The slag is technologically cooled withwater. Spilled waters from the boiler scraper, together with the waters from the boiler room washing, electrostaticprecipitator plateau washing and waters from the mills' cooling (all has similar composition like spilled waters from thescraper), are collected in the collection pit. The water from the collection pit (i.e. as we call it 'the scraper water') hasingredient particles of slag, ash and coal. They are transported through pumps to the plants for the waste water treatment,specifically into re-circulation reservoir (there are two reservoirs, with equal volume, each per 500 m3). In the first reservoir,the particles of slag, ash and coal are gravitationally settled, while the water above the mud is spilled over into otherreservoir. The part of water from this reservoir is used for wetting the ash, while during the third shift when there is nowetting of ash, the small amount of this water is directed to the lagoon which is intended for acceptance and treatment ofmud waters from the de-carbonization process of raw waters and washing the sand filters.Once the first reservoir is filled with mud (5.5 m3 /day), the mud is thrown with "ULT" machine on the land beside thereservoir, and then it is transported to the ash disposal site by trucks. The reservoir of mud has to be cleaned every 50-60days, so that there are enormous soil beside the reservoir.

2. The carbonated mud originates in de-carbonization process of raw waters at the reactor - type "Lurgy", with maximumcapacity of 900 m3/h of de-carbonated water. The chemical process of de-carbonization is performed by adding the solutionof lime milk and the solution of Ferro-sulfate (FeSO4 x 7 H2 0). There is a production of approximately 3,500 m3 of mud

2

par year. Produced mud is directed to the r eption reservoir at the waste water plants, and then it is transported to thec rbonated mud disposal site through the pip ng (volume 40,000 m3). The carbonated mud disposal site is around 800 ma vay from the waste water treatment plants.

solution of environment.Considering the question about necessity of further activity on the environment protection improvement, all persons gave their opinions, and a large number of them included also

activities on the environment protection in Gacko town.

Conclusion

On the basis of all above-said, the following conclusion could be drawn. The environment protection is not at the enviable level, and it is necessary to work on this problem more than so

far. The construction of the mine and the thermal power plant Gacko means a lot not only for Gacko municipality but also for the whole Republic of Srpska. Its importance is huge in the

sense of economy growth, employmetit, increase of total revenue. Construction of the second phase of the TPP Gacko would improve coal and electric energy provision, solve the

municipal infrastructure, as well as the problem of unemployment. A general conclusion could be reduced to the fact that the positive effects of the second construction phase of the TPP

greatly surpass the negative ones, under condition to take adequate concern about environment protection. The inhabitants also express the necessity to have the water flow nearby town
