1. PROPERTIES OF THE PROJECT

1.a The Project’s Work Flow Scheme, Capacity, Covered Area, Technology, Personnel Number

Horyan Regulator and HEPP Energy Project that are subjects to the Project, located over the

Horyan Creek and Kara Creek within the borders of province of Trabzon, Arakl� district. Project area Site Location Map is given in Annex-1, and 1/25.000 Scaled General Settlement Plan is given in Annex-2. The project in question is located at Trabzon G44-a4 section. There are no other facilities in the basin where Horyan Regulator and HEPP project is located. The purpose of the project is only generation of electrical power and it does not have any other goals such as irrigation and overflow control.

In terms of project capacity, while the project was out of the scope according to provisions of

Environmental Impact Assessment (EIA) Regulation which entered into force by being published in the Official Gazette No. 25318 dated 16.12.2003, with the demand of the project owner to improve its capacity the project was considered under the scope of Article 28 of “The List of Projects to be Applied Election Selection Criteria (Annex-II) of the EIA Regulation titled Energy Tourism Housing which entered into force by being published in the Official Gazette No. 26939 dated 17.07.2008, and has been evaluated Under the scope of river type power plants with established power of 0,5 MW and higher and accordingly this Project Information File hereby was prepared.

Arsan Energy Inc. is planning to construct and operate Horyan Regulator and HEPP Project.

In this regard, water utilization right agreement has been signed with SHW General Directorate and production license No EÜ/1398-8/1022 and dated 06.12.2007 has been obtained. The production license that was obtained on behalf of Arsan Energy Inc. has been transferred to Horyan Energy Inc. with EPDK writing with 25.05.2009 decision date and 86 decision number. (see Annex-4).

Technology and Work Flow Schedule of the Project The recommended facilities within the scope of the project are Horyan Regulator and

sedimentation tank, GPR pipe (Channel + Tunnel), surge chamber, penstock pipe and power plant building. Moreover, in order to store the earthmovings of the excavation works the non-operating tallow area with approximate size of 34.780 m2 at Ka��kç� position that belongs to Kaletepe Stone mill management shall be used as casting area. Within the same area there shall be an in-site building to provide accommodation and meet the daily needs of the construction personnel. The property of the Stone mill belongs to the treasury. In case of this storage area is not evacuated by the Treasury a protocol shall be conducted with Arakl� Municipality and the earthmovings shall be stored in an area that the Municipality considers suitable in accordance with provisions of “Earthmoving Soil, Construction and Debris Control Regulation”. All covered areas and coordinates of all units are given at the below tables and their locations within the project area are given in Annex-2 1/25000 Scaled General Inhabitance Plan.

In order to provide transportation within the scope of the project, utilization of the existing

roads shall be provided after they are restored as much as possible. During the road restoration private areas will not be damaged. In case of damage to private areas during road works, after the panel of experts determines that the damages are caused by project construction activities, the damages of the private area owners shall be covered by the project owner. In case of opening new roads, minimizing logging shall be decisive for the selection of the routes.

Number of the Personnel Under the scope of the Horyan Regulator and HEPP project, mostly unqualified

approximately 20 people are planned to be hired for the construction stage. In management stage, mostly qualified approximately 5 people are planned to be hired to work in the power plant for maintenance and control works.

Life of the Project


6

The construction activities of the project are planned to be completed in 2 years. Economical life of the project is determined as 49. However, as a result of renewal of the electromechanical equipment and regular performance of periodical maintenance it is possible to provide service for more years.

After the facility completes its life span, if necessary area leveling, shaping and terracing

works shall be conducted for land development. Also, during the land development works, in order to prevent deposition of the surface flow

on the area that may be caused by precipitations, surface drainage shall be controlled by digging drainage channels and dykes at necessary locations.

1.b Utilization of the Natural resources (Land Use, Water Use, Type of the Used Energy

etc.) Land Use The facilities under the scope of the project and the area covered by these facilities are given

in Table-1. According to this approximately 74.520 m2 area shall be used Under the scope of the project.

Within the area on which the Horyan HEPP project is to be provided there are treasury,

private property and forestry lands. Necessary permits for the total area of 22.102 m2 that the Penstock Pipe, GRP Pipe Route, Regulator and Sedimentation tank shall be located has been obtained from the Ministry of Environment and Forestry, General Directorate of Forestry and related documents and Area Delivery Receipt Report are given in Annex-4. Before the project in question begins to its activities, plans and reports of confiscation shall be prepared. The applications that shall be carried out according to qualifications of the land that the project shall be located are explained at Section 2.a.

Water Use In scope of the project, preparation of the land, providing drinking and cleaning water for the

workers during construction and management stages is necessary. The water is also needed to prevent the dust. Under the scope of the construction there shall be 20 workers and as estimated at Section 1.c, daily 3 m3 water supply is foreseen. For dust control approximately 5 m3 water supply is needed daily. The subject drinking water shall be provided from the hygienic commercial water in the market and the potable water shall be provided from the water tanks at the near inhabitant areas.

In the project in question, the waters taken from the Horyan Creek through regulator structure

shall generate power and be released to Kara Creek bed. For this reason, a specific amount of the water in the Horyan Creek shall be utilized for energy use. In order to support the natural life in Horyan Creek life line water shall be released.

During the conducted feasibility studies, it is detected that the tunnel construction does not

block the underground water. However, in case the ground water comes up during the tunnel excavation works, this water shall be removed according to provisions of WPCR (Water Pollution Control Regulation).


7

There is no water usage between the Regulator and the power plant such as well, fish production facility.

Life Span Water Estimation The structures build over the rivers in scope of the water resources development projects

affect water amount, quality and consequently the water ecosystem. In this direction, in order to provide continuity of the economic and ecological values of the realized projects by protecting them, the life span water that shall be let flowing downstream should be determined and released to the river bed.

Life span water is determined as the amount of water flow within the rivers needed to

preserve the habitats in these rivers. Today regulation/legislations that manage the flow that is necessary for the biological needs

of a river are not present in many countries. However, there are many methods to be used to determine the amount of the water that should be left in the river for supporting the life within the river. What is the important thing for aquatic creatures in each method is different. For this reason, these methods depend on different acceptances. Consequently, the estimation was carried out via Tennant method that is approved and used frequently by SHW.

Tennant (or Montana) method (1976) is used in at least 25 countries as its original and

modified versions. The most important reason to choose this method is its simplicity and easy application. A percentage of annual average flow (AAF) is used in order to define the flowing conditions regarding the flow regime, wild life, recreation and similar environmental values for different two 6 months period (Table 6). Tennant (1976) gave them some recommended flow regime names as October-March and April-September.

Table 6 Tennant (Mortana) Method:

Definition of General Flow Conditions

Recommended Flow (as a Percentage of AAF)

Recommended Flow (as a Percentage of AAF)

Overflow or Maximum 200 % 200 % Optimum Range 60-100 % 60-100 % Perfect 40 % 60 % Very Good 30 % 50 % Good 20 % 40 % Moderate 10 % 30 % Poor 10 % 10 % Very Poor <10 % <10 %

In this method 10% of annual average flow indicated as “poor”, 30% as “moderate”, %40 and more as “good” for habitat conditions.

Water resource of Horyan Regulator and HEPP Project is Kara Creek and its branches.

Horyan Regulator is over Horyan Creek which is a branch of Kara Creek. Flow Observation Stations and Project Place Flow Estimations Water supply of Horyan Regulator area; is estimated from the daily flow data of Sürmene

Creek – Ortaköy Flow Observation Station (FOS)No. 22-53 (SHW) that is established over


8

Sürmene Creek. FOS No. 22-53 (DS�) has benn active since 1979. No. 22 -53 (SHW) flow monitoring station 1979-1989 and 1992-1993 period has been evaluated. There is no flow monitoring data 1990 - 1991 and 1994 - 2002 monitoring period. Invaluable years have been obtained via correlation carried out for 1979 – 1989 the matching years of Kara Creek – A�nas FOS No. 2202 (E�E). The meaningful correlation equation between FOS’s No. 22-53 (SHW) and No. 2202 (E�E) has been found as: y = 0.8976 * X07212, R = 0.80. With this found correlation equation daily average flow values has been completed for the missing 1990 - 1991 and 1994 - 2002 years period and for the FOS place No. 2253 (DS�) 1979-2002 monitoring period uninterrupted flow monitoring values was obtained.

The daily flow rates of Horyan Regulator location was found by transferring the daily flow

values of the FOS No. 22-53 (DS�) between 1979 - 2002 monitoring period Horyan Regulator precipitation for 50.0 km2 Q = C x An (n = 1.0) formula with area rate. Later these values were controlled with FOS No. 22/77 and found consistent.

Horyan Regulator monthly average flow rates are given in Table 7. Table 7 Horyan Regulator Monthly Average Flow Rates (m3/s)

Excavator 250 HP=187 kW 107 dBA Driller 250 HP=187 kW 107 dBA Truck 150 HP=112 kW 104 dBA Track loader 156HP= 116 kW 107 dBA Sprinkler 121 HP = 90 kW 103 dBA *** 1 HP= 0,746 Kw

Estimation of Sound Power Level of the Machinery Following the formulas given in Table 18 Sound Power Level of each machine is estimated as

below. Excavator: Engine power of the Excavator to be used at the project area is 250 HP = 187 kW. As the

evaluation result for the Excavator given in Table 19 is, P = 187 kW > 15 kW, "80 + 11 logP" formula was used in sound power calculation;

Lw = 82+11 log 187= 107 dBA Driller: Engine power of the Driller to be used at the project area is 250 HP = 187 kW. As the

evaluation result for the Driller given in Table 19 is, P = 187 kW > 15 kW, "80 + 11 logP" formula was used in sound power calculation;

Lw = 82+11 log 187= 107 dBA

Truck: Engine power of the truck to be used at the project area is 150 HP = 112 kW. As the

evaluation result for the truck given in Table 19 is, P = 112 kW > 55 kW, "Lw= 82 + 11 log P" formula was used in sound power calculation;

Lw = 82+11 log 112= 104 dBA

Track Loader: Engine power of the Track loader to be used at the project area is 156 HP = 116 kW. As the

evaluation result for the Track loader given in Table 19 is, P = 116 kW > 55 kW, "Lw= 84 + 11 log P" formula was used in sound power calculation;

Lw = 84+11 log 116= 107 dBA

Sprinkler:


28

Engine power of the Sprinkler to be used at the project area is 121 HP = 90 kW. As the evaluation result for the Sprinkler given in Table 19 is, P = 90 kW > 55 kW, "Lw = 82 + 11 log P" formula was used in sound power calculation;

Lw = 82+11 log 90 = 103 dBA

Article 23; (70 dBA)

When Table 27, which was obtained by performing the necessary estimations is evaluated, the total sound level according to distance caused by the machinery used at the sites drops down the allowed value after 50 meters.

The closest settlement areas to Regulator site are A��kl� Town approximately 800 m far away

and Çapanl� (Yeniköy) village approximately 820 m far away. Nearest house is 100 m away from the area. The total sound level according to distance caused by the machinery to be used at the site drops below the allowed level after 50 meters. For this reason, it is foreseen that the noise level caused by the machinery at the site will not affect the nearest settlement areas and connected houses in a bad way.

In scope of Horyan Regulator and HEPP Project, the route that the GRP Pipe shall be installed

is at 3 km. part of Ye�ilyurt City road, at the cutting bevel side. Approximately 1000 m part of the GRP Pipe will pass through Yoncal� Village. There are structures like house, mosque, graveyard, well etc. on the village road. GRP pipe construction of in total 4.428,18 m length is planned to be finished in 6 months. The works on the village road is foreseen to be finished approximately in 2-3 months. For this reason, it is predicted that the bad effects of the noise caused by the operating construction machinery on local citizens shall be short term. Also, the noise level in reality is foreseen to be very lower than the estimated value as the estimations were conducted as the worst case scenario that all the machines are working together at the same time. All necessary measures shall be taken in order to provide the local citizens not to be affected by the noise during the works to be performed at the village road and prevent the accidents to be occurred at the working area and the construction works are planned to be finished within the shortest period.

Closest settlement area to the Penstock Pipe construction site is 420 m far Yoncal� Village.

The nearest home is 95 m away from the area. It is predicted that the machinery to be operating at the construction works will not have any negative effects on the nearest settlement areas.

Closest settlement area to the HEPP site construction area is 660 m far Yoncal� Village. The

nearest home is 125 m away from the area. It is predicted that the machinery to be operating at the construction works will not have any negative effects on the nearest settlement areas.

It is predicted that the real noise level shall be lower than the estimated value as we consider

that the estimations are performed as the worst case scenario that all the machinery is operating at the same time and the project construction shall be improving continuously.

Provisions of “Evaluation and Management of Environmental Noise Regulation” that entered into force by being published in the O.G. No. 26809 dated 07.03.2008 shall be complied with strictly.

The measures to be taken against the noise to be present are stated at Section 1.d. b)Estimation of Noise Level Caused by the Machinery to be used at Construction of

Transmission Tunnel The list of the machinery and the noise level of these machines that shall be used at

construction of Transmission Tunnel are given in Table 19. This data was estimated in accordance with “Evaluation and Management of Environmental Noise Regulation” that entered into force by being published in the O.G. No. 26809 dated 07.03.2008. Noise estimations to be caused by the machinery to be used at the other sites and the noise estimation method of the machinery to be used at Transmission Tunnel construction site are the same and the estimations were repeated.

The total sound level of all sources of noise at the construction of the Transmission Channel

according to distance at 4 octave band are given in Table 28. Table 28 The Total Sound Level of all Sources of Noise at the Construction of the

Article 23; (70 dBA)

When Table 28, which was obtained by performing the necessary estimations is evaluated, the total sound level according to distance caused by the machinery used at construction of Transmission Tunnel drops down the allowed value after 50 meters. Yoncal� Village is the nearest settlement area to the Transmission Tunnel construction area that is planned to be conducted in scope of the project. The nearest home to the tunnel inlet is 40 m far away.

In order not to affect the houses close to tunnel area from the explosion works, the amount of

explosives to be placed in each hole shall be reduced. These amounts shall be determined at decisive project phase. The explosions to be performed inside the tunnel are foreseen not to affect the close houses.

Also, it is predicted that the real noise level shall be lower than the estimated value as we

consider that the estimations are performed as the worst case scenario that all the machinery is operating at the same time and the Transmission Tunnel construction works shall be performed underground. It is predicted that the machinery to be used at the construction works will not affect the closest settlement areas negatively.

The measures to be taken against the present noise are stated at Section 1.d.

Emission


38

Land Preparation and Construction stage Type and amount of the emission to be produced by the diesel burning by the vehicles to be

working during the land preparation and construction stage are estimated at Section 1.c for all units. When this values estimated for Horyan Regulator Site are compared with “Molar Values”

according to “Controlling the Air Pollution caused by Industrial Facilities Regulation” given in Table 2.1, it is observed that none of the emission values exceed the threshold value stated at the regulation. For this reason, the project is foreseen to be harmless to the environment.

All conducted estimations are performed as if all machinery is working in 1 hour. However,

this is a very low possibility. Also the construction stage is predicted to last 42 months, so the estimated emissions will take place during this period and there shall be no problems after the construction is completed.

Exhaust measuring of the Heavy Duty Machines and trucks shall be performed regularly and

the limit exhaust values will not be exceeded. During the activity in question the provisions of “Controlling the Air Pollution caused by

Industrial Facilities Regulation” that was published in the O.G. No. 26236 dated 22.07.2006 shall be complied with.

Operation stage For accommodation of the personnel that shall be working at the operation stage the social

facilities shall be utilized. Electric power is used for warming purposes at this place, fuel use or emission production is out of subject. There shall be no emission during the operation stage.

Dust Formation Land Preparation and Construction stage Dust emissions and their mass flows to be formed by the performed works during land

preparation and construction stage are estimated at Section 1.c. When the dust flow to be occurred at Horyan Regulator site is compared with “Molar Flows”

according to “Controlling the Air Pollution caused by Industrial Facilities Regulation” given in Table 2.1, the values that estimated for construction stage are detected to be below the limit value (> 1,5 kg/hour). The dust formation to be occurred during land preparation and construction works is foreseen not to affect the close settlement areas for reasons such as the Horyan HEPP site is quite rough, the settlement units are very far from the work area and various measures shall be taken against dust formation at all work areas.

In all works to be performed in scope of the projects, in order to minimize the dust to be

present the below measures shall be taken. � The material at the trucks shall be covered with canvas during transportation. � Attention shall be paid to load and unload without winnowing. � There shall be speed limits for the vehicles working at the site. � Spraying work shall be conducted at working sites and service roads.


39

For workers health the provisions stated at T.R. Ministry of Labor and Social Security, Occupational Health and Safety Legislation shall be complied with.

Operation stage There is no possibility of dust emission during Horyan HEPP project operation stage. Noise Land Preparation and Construction stage The noise level to be formed is estimated at Section 1.c. The estimations in question are preformed as if all sources of noise are working at the same

time at the same place. However, it is a quite low possibility that all of them are working at the same during the same working hours continuously. Also; various effects such as the noise is not continuous but in certain time intervals and variable, the area is rough and surrounded by woodland are expected to reduce the received noise level by the inhabitants.

In order to protect the health of the workers at the noise exposure areas and keep the

continuity of the activity adequate protective tools and equipment such as helmets, earpieces and ear taps shall be provided. During the management the workers are planned to be working for 8 hours in compliance with occupational health rules. Also, Heavy and Dangerous Works Legislation Article 2 shall be complied with.

During the operation activity provisions of Environmental Noise Evaluation and Management

Regulation that was published in the Official Gazette No. 26939 dated 17.07.2008 and T.R. Ministry of Health and Social Assistance, Occupational Health Legislation shall be complied with.

Operation stage

After the facility passes to operation stage, movement of the turbine shaft around its axis at the power plant building will produce noise. However, as all kinds of insulation shall be established within the building, there is no noise in question that is caused by the power plant building and received by sensitive receiver. The nearest house to the power plant building is at 250 m distance.

Transmission Tunnel Explosion Technique and Details For 1013 m tunnel within the scope of the project approximately 7.160 m3 tunnel excavation

shall be carried out. 300 cm tunnel excavation shall be performed with a single explosion and the progress shall be made by daily explosions. For tunnel explosion 1.8 kg explosive material is planned to be used for 1 m3 tunnel excavation. In this case 26 m3 excavation material shall be provided for 300 cm tunnel digging. For 26 m3 tunnel digging 46,8 kg explosive material shall be used. In tunnel explosion in one shot 40 holes shall be opened and 1,80 kg dynamite, 1 capsule shall be used for each hole. In this case, in total for 7.160 m3 tunnel digging approximately 12.888 kg dynamite shall be used.

Except environmental problems such as vibration and dust caused by the explosions

performed underground it will not affect the environment. Nevertheless, environmental problems may be caused by the explosion to be carried out at entrance and exit of the tunnel, but as both ends of the tunnel is far away from settlement areas and the amount of explosive material to be used is


40

small, it is foreseen that no negative effects to the environment shall be made. No explosion shall be carried out for Transmission Channel construction.

Necessary permits for carriage and usage of explosive materials shall be obtained from

Trabzon governorship. The explosive material will not be stored at the site and if considered necessary shall be transferred to project site.

Explosive materials shall be stored in wooden boxes according to related regulations, far

away from construction site and settlement units. Dynamite and capsules shall be kept in separate places, the preservation of the area shall be provided with wire fences and warning and caution signs. For explosion works trained and experienced stoker shall be hired.

Some taxonomies that they are said to be present in Turkish Flora, but could not be found in spite of special searches are placed in this category.

EW - Extinct in the Wild: If the taxonomy could not be found in spite of searches carried out

in areas that it may be present, so it is lost and keep living alone in a isolated culture it is placed in this group.

CR - Critically Endangered: If a taxonomy is in risk of being extinct in very near future it is

placed under this group. In the floristic studies carried out, plant taxonomies that their future populations were thought to be harmed are placed in this category.

EN - Endangered: If a taxonomy is under very high risk and in danger of to be extinct in near

future, but not in CR group it is placed in this category. VU - Vulnerable: While they are not placed under CR and EN groups, taxonomies that are in

high danger in the nature for intermediate term future are placed under this group. LR - Lower Risk: Plants that are not placed in higher level danger groups, having better

populations comparing to them are placed in this category. Ones with quite good populations and known at least in 5 locality are placed in this category. There are 3 sub-categories to be listed according to threat in future situation:

a- (cd) - Conservation Dependent: Taxonomies to be categorized under one of the groups in 5

years. The ones that require a special protection status both from angle of type and habitat. b- (nt) - Near Threatened: Ones that are not placed in the previous group but close to be

placed under VU category. May be under threat.


48

c- (lc) - Least Concern: Ones that does not require any protection and is not under any threat. DD - Data Deficient : If data regarding distribution and amplitude of a taxonomy is not

adequate the taxonomy is placed under this group. Even if biology of a taxonomy under this group is well known, data concerning its distribution and amplitude is incomplete.

NE - Not Evaluated -: Taxonomies that could not be evaluated with any of the above criteria

is placed under this group. The studies on the Turkish fauna are mostly about taxonomy and fauna studies performed on

the basis of region and basin are very low. In this regard, there are no fauna studies conducted previously for the project site and neighboring area.

Fauna types show seasonal differences and as determining fauna inventory of an area may last

a couple of years, the species given at fauna lists were prepared by; besides field surveys, take observations and hearings of the local people, biotope properties of the region, present distribution areas and existing biogeography rules into consideration. Fauna lists, include the species that are put forth via literature researches carried out for their existence in the environment but were not seen during the field survey.

Although there is no important living habitat on the project area, in the studies conducted by

taking the near area into consideration the fauna species at the region were investigated under three titles as Reptiles, Birds and Mammals. Species living or have the possibility of living at the project site and neighboring area are shown in a table in Annex-11.

For the species placed at the protection lists belonging to 2008-2009 Hunting Period that were

prepared according to decisions of T.R. Ministry of Environment and Forestry Nature Protection and National Parks General Directorate Central Hunting Commission, activities shall be carried out in accordance with protection measures stated at this commission decisions.

� Wild animals included in Annex-I List are put under protection with 2008-2009 Hunting

Period Central Hunting Commission Decision of Ministry of Environment and Forestry Nature Protection and National Parks General Directorate.

� Hunting animals included in Annex-II List are put under protection with 2008-2009

Hunting Period Central Hunting Commission Decision of Ministry of Environment and Forestry Nature Protection and National Parks General Directorate.

� Hunting animals included in Annex-III List are species that are allowed to be hunted in

certain periods according to 2008-2009 Hunting Period Central Hunting Commission Decision of Ministry of Environment and Forestry Nature Protection and National Parks General Directorate.

Fauna species are put under protection in two sections according to Bern Agreement. Those

are: II- Fauna species certainly put under protection a) All kinds of catching, capturing and killing on purpose, b) Damaging and harming breeding and recess areas on purpose, c) Disturbing the wild fauna especially in breeding, growing and winter sleep periods on

purpose, against the purpose of this agreement,


49

d) Collecting eggs from wild life or damaging on purpose or capturing eggs even if it is empty,

e) It is prohibited to keep fauna species alive or dead and performing internal trade over them.

III-Protected fauna species 1. All kinds of catching, capturing and killing on purpose, 2. Damaging and harming breeding and recess areas on purpose, 3. Disturbing the wild fauna especially in breeding, growing and winter sleep periods on

purpose, against the purpose of this agreement, 4. Collecting eggs from wild life or damaging on purpose or capturing eggs even if it is

empty, 5. It is prohibited to keep fauna species alive or dead and performing internal trade over

them. If we look at the effects of the project on flora and fauna; Regulators are construction build

over rivers. During the construction stage; the structures that field study to be conducted are Transmission Tunnel, Penstock Pipe and power plant areas. During the field studies, the species to be removed have a great distribution rate, so by removal of these species the generation of the species will not be endangered, but a biomass lost will in question. During site preparation and construction stage territorial fauna shall be affected. As there shall be explosions at the tunnel mouth, it is foreseen that the territorial fauna will back off to near similar biotopes because of the noise caused by explosions. The effect of the Regulator construction to the aquatic fauna, in result of grazing works to be conducted at slopes an amount of soil shall be mixed to the water and the river water may be muddy in certain time intervals. This temporal situation will spoil the suitable habitat in the water for the living creatures. In order to perform construction of Regulator, sedimentation tank and gravel pass dry Derivation Tunnel and Coffer Dam shall be built. During the construction stage primarily the water shall be derived from the right slope and the water reservoir structure and gravel pass at the left slope shall be established, later the water shall be taken into this part and the rest of the Regulator is planned to be completed. In terms of construction techniques, there no chemicals shall be used during concrete production.

3. ALTERNATIVES TO PROJECT AND PLACE The project in question is planned to be established on Horyan Creek and Kara Creek and it

will not be used for any other purposes than power production. The fore geological studies conducted proved that the place is geologically adequate.

4. CONCLUSIONS Horyan Regulator and HEPP Energy Project that are subject of the Project are placed on

Horyan Creek and Kara Creek within the borders of province of Trabzon, Arakl� district.

The project subject to the report consists of Horyan Regulator, Transmission Tunnel, Transmission Channel, Penstock Pipe and Power Plant Building facilities.

Installed power of Horyan Regulator and HEPP project that is carried out by operation works

with daily currents is 5,68 MW. Effects to Aquatic Environment In scope of the activity, in result of meeting the daily needs of the workers to be working at

land preparation-construction and operation stage domestic waste water shall be produced. The cesspool to be established shall be placed within the construction site and the waste water collected at the cesspool, shall be removed by vacuum trucks of the municipality after conducting protocol between Arakl� Municipality an activity owner.

For removal of the domestic wastewater to be produced during land preparation and operation stage the provisions of Water Pollution Control Regulation published in the O.G. No. 25687 dated 31.12.2004 shall be complied with. By taking the necessary measures the waste waters to be produced during the construction works are foreseen to be harmless to the environment.

Solid Waste Production and Its Effects During land preparation-construction and operation stages, domestic solid waste shall be

produced in result of meeting daily needs of the workers. Solid waste to be produced shall be collected in closed containers without polluting the environment and shall be transferred to Arakl� Municipality solid waste collection site. For collection, storage and transfer of the solid wastes, the provisions of Solid Waste Control Regulation shall be complied with. By taking the necessary measures the solid wastes to be caused by the activity are foreseen to be harmless to the environment

Effects to Air Emission type and amounts caused by the vehicles to be working during land preparation and

construction stage are estimated at Section 1.c. All dust estimations are performed as if all vehicles shall be working at the same time in the

same area and this is a low possibility. Also, they are estimated as if there shall be no measures to be taken against dust to be formed. These estimated emissions shall be formed during 2 years that the construction works to be carried out and there shall be no emission in the operation stage of the activity.

During construction and management of the activity in question, the provisions of “Control of

the Air Pollution Caused by Industrial Facilities Regulation” that was published in the O.G. No. 26236 dated 22.07.2006 shall be complied with.

Noise Formation and Its Effects


52

Estimation of the noise level to be caused by the land preparation and construction works in

scope of Horyan Regulator and HEPP project is given at Section1.c. These values that were estimated according to closest settlement areas and distances and stated above have been evaluated under the scope of Evaluation and Management of Environmental Noise Regulation that was published in the Official Gazette No. 26809 dated 07.03.2008. The estimations in question has been estimated as if all sources of noise are working at the same time and in the same place. However, it is a quite low possibility that all of them are working at the same during the same working hours continuously. For this reason, no negative effect is expected on the closest settlement units caused by the activity. These works shall be only carried out during land preparation and construction stages and during operation stage there shall be no works to be carried out that would cause noise.

In order to protect the health of the workers at the noise exposure areas and keep the

continuity of the activity adequate protective tools and equipment such as helmets, earpieces and ear taps shall be provided. During the management the workers are planned to be working for 8 hours in compliance with occupational health rules. Also, Code on Heavy and Dangerous Works Article 2 shall be complied with.

During the operation activity provisions of Environmental Noise Evaluation and Management

Regulation that was published in the Official Gazette No. 26809 dated 07.03.2008 and T.R. Ministry of Health and Social Assistance, Occupational Health Legislation shall be complied with.
