DEFINITION AND OBJECTIVE OF THE PROJECT
Oskan Regulator and Hydroelectric Power Plant is located 14 km to the northwest of
Osmaniye Province, within the borders of Duzici District and on the Ceyhan River. The
approximate head is 21 m between the upstream Aslantaş Dam and HEPP and
downstream Cevdetiye Irrigation Regulator. This head is planned to be utilized through
upstream Oşkan HEPP and Berkman HEPP.
With an installed power of 3x10 MW, Oskan HEPP will generate 109,93 Gwh/year in total,
49,09 Gwh/year of which is reliable.
Turkey is a rich country in terms of hydroelectric energy sources. However, only 11% of
annual capacity estimated to be 108,5×109 can be used. This is nearly the half of our total
annual energy consumption while the rest of it is provided from thermal sources and
abroad.
Berkman HEPP and upstream Oşkan HEPP planned together are two plants which will be
established in order to make use of the 21-meter head between Cevdetiye Regulator and
Aslantaş Dam on Ceyhan River. Total annual energy generation of the two regulators,
each of which have 10,5 m heads, is 219,86 Gwh. This generation occupies an important
place within Ceyhan Basin.
Inasmuch as the state sector has to undertake investments of large dams, the authority to
establish and operate the facilities bearing the quality of this type of “River type Power
Plants” which do not require investment was granted to the private sector on 19/12/1984
with Law No. 3096. Oskan HEPP feasibility works desired to be conducted by benefiting
from this law are carried out by TEMELSU Muhendislik Limited Şirketi (TEMELSU
Engineering Limited Company).

1. NON-TECHNICAL REPORT SUMMARY The construction of Oskan Regulator and Hydroelectric Power Plant on Ceyhan River in
the Duzici District of the Province of Osmaniye is planned by the “PARTNERSHIP OF
ÖZALTIN İNŞAAT TİCARET VE SANAYİ A.Ş-NUROL İNŞAAT VE TİCARET A.Ş.” The
closest settlement unit to the project area is Karagedik Village, which is approximately 1,5
km away.
Oskan HEPP is a plant which will be established in order to make use of the 21-meter
head between Cevdetiye Regulator and Aslantaş Dam.
Construction stage of the project is expected to be completed in 3 years.
Area of the facility to be established remains outside the borders of adjacent area.
While 100 persons will be employed at the construction stage of the Hydroelectric Power
Plant, 5 persons will be employed at the operation stage. Within the scope of the project,
general needs such as food, shower, WC etc. of the employees at construction stage will
be provided from the prefabricated site building to be set up and the same needs will be
met at the power house building at the operation stage.
Economic life of the facility is reckoned to be 30 years depending on the changing and
advancing technology. With the hydroelectric power plant constructed through this project,
energy requirement of the Region that cannot be met will be satisfied to a large extent.
With the advancing industrialization, the need for energy, which is already scarce,
increases. For this reason, energy requirement of the industrialists and the whole region
will be largely met thanks to the HEPP to be constructed.

b) Interaction with the Other Facilities around It Osmaniye Province and its vicinity have high development potential in agriculture,
industry, trade and tourism. Development of these sectors gives rise to new energy and
water requirements. Ceyhan River emerges as one of the closest sources to consumption
centres.
The most significant facilities among the ones that have been put into operation on
Ceyhan River is Aslantaş Dam and HEPP. This facility carries the purpose of irrigation,
flood protection and energy and has an installed power of 3x46MW. Its elevation from the
base is 95m, elevation from riverbed is 78m and it is an earth fill-type dam.
Kartalkaya Dam planned for irrigation is on the Aksu branch of Ceyhan River, is in
operation also. This earth-fill type Dam has an elevation of 57 m from the base while it is
56 m from the riverbed.
Menzelet Dam, which is in operation, has an elevation of 150,50 m. from the base and it is
130,50 m from riverbed and it is rock fill type. Power plant of Menzelet Dam planned for
irrigation and energy purposes, has an installed power of 4x30MW.
Downstream of Menzelet Dam is Sır Dam and has an elevation of 116 m from the base
and it is in concrete arch type. Sır HEPP has an installed power of 3X46MW.
Düzkesme Dam and Berke Power Plant Projects, which are downstream of Sır Dam, is
completed. Elevation of the concrete arch-type dam from the base is 83m. Berke Power
Plant has an installed power of 3x56MW.
Among the above-mentioned facilities, Aslantaş Dam is the most downstream one.
Approximately 23km downstream this dam is Cevdetiye Irrigation Regulator. There is a
head of around 21 m between Aslantaş and Cevdetiye Regulator. Berkman HEPP and
Oşkan HEPP, which is a similar work, were planned to make use of this head. Both of the
power plants were planned to have a power of 3x10MW.
BOZAT INC.
OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 9
Inflow in Berkman Power Plant is formed by the outflow of Okşan HEPP, which is
upstream of it. However, like Berkman HEPP, Okşan HEPP is a facility with no storage.
For this reason, inflows are formed by outflows of Aslantaş Dam for both of the facilities.
The project has no interactions with other facilities than the above-mentioned ones.
c) Use of Natural Resources Construction of Regulator and the Hydroelectric Power Plant on Ceyhan River is planned
with the project. Water will be used as natural resource during the activity. The projected
HEPP will be operated as run-of-river plant. In general terms, the flow coming into the
reservoir on any day will go out of the reservoir in a short time in practice. When the
overflow currents reach the maximum level, the excess current will pass through the
spillway and released to the natural riverbed. In the case that the project is operated in this
way like a run-of-river plant, there will be no adequate time for significant changes
(Physical, chemical etc.) in water quality. The water is not expected to have a negative
impact on surface water resources as the projected HEPP Facility is run-of-river type plant
and water is released back to the river directly at once without delay.
d) Waste Generation i) Liquid Wastes
A. Construction Stage
The following will occur at construction stage of the project:
1. Concrete production,
2. Preventing dust formation,
3. Water consumption in order to meet drinking and utility water needs of the employees.
BOZAT INC.
OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 10
It is assumed that approximately 100.000m3 water will be used for concrete works and
300.000m3 water will be used for the prevention of dust formation which makes 400.000m3
in total. This water required for the construction will be supplied from Ceyhan River.
It is not expected that a significant amount of wastewater will be generated as a result of
water use for the purpose of concrete production and the prevention of dust formation. A
large part of this water will fade through natural infiltration while the remaining part will
evaporate.
Apart from these, water will be used for the purposes of meeting the daily drinking and
utility water needs of the personnel to be employed during land preparation and the
construction of the facility. The number of personnel to work at construction stage of the
project is 100. The following results are reached, if the amount of water required per
person is considered to be 150 lt/day:
The number of workers to be employed : 100 persons
The amount of water to be used : 150 lt/person-day = 0.15 m3/person-day
Total water requirement : 0,15 m3/person-day x 100 persons =15 m3/day
This water, which is required as drinking and utility water, will be brought from nearby
villages to the facility area by tankers.
If it is deemed that the whole water used will return as wastewater, it can be seen that the
total amount of domestic wastewater to be generated in the area is 15 m3/day.
The pollutants contained in typical untreated domestic wastewater and their average
concentrations are given in Table- 2.d.1.

This domestic wastewater to be formed will be collected in watertight cesspool to be built
pursuant to provisions of the “Regulation on the Pits to be excavated where Sewer System
Construction is not Possible” of the Ministry of Public Health and Welfare enforced upon
publication in the Official Gazette dated 19.03.1971 and No. 13783. Watertight cesspool
plan is given in Figure 2.d.1. Wastewater accumulating in the cesspool at the operation
stage will be limed at regular intervals and disinfectant substance will be added to it in
order to prevent spread of smell and endemic diseases. Wastewater accumulating in the
cesspool will be vacuumed by Municipality of Duzici with sewage truck and discharged into
the sewage system.

B. Operation Stage Number of personnel to work at the operation stage of the project is 5. If water amount
required per person is considered as150 lt/day:
Number of workers to be assigned : 5 persons
Water amount to be used : 150 lt/person-day = 0,15 m3/person-day
Total water requirement : 0,15 m3/person-day x 5 people = 0,75 m3/day
This water, which is necessary as drinking and utility water, will be brought from nearby
villages to the facility area by tankers.
If it is deemed that the whole water used will return as wastewater, it can be seen that the
total amount of domestic wastewater to be generated in the area is 0,75 m3/day.
The pollutants contained in typical untreated domestic wastewater and their average
concentrations are given in Table-2.d.2.

This domestic wastewater to be formed will be collected in the lavatories to be constructed within
the power house building. Wastewater accumulated will be vacuumed by the Municipality
with sewage truck and discharged into the sewage system
ii) Solid Wastes
A. Construction Stage
We can divide the wastes to be formed at the construction stage within the scope of the
project into five main categories.
1st Group: Formwork wood residues,
2nd Group: Construction iron, iron pipe, profile, rubber etc.
3rd Group: Concrete and injection residue materials
4th Group: Domestic solid wastes
5th Group: Excavation to be formed during land preparation
The wood wastes used for formworks will be collected at certain intervals. In case of
demand, the wood wastes collected will be given to peasants in the vicinity and these
wastes will be used for the purpose of heating. The second group wastes will be collected
at certain intervals and sold to waste collectors. Third group solid wastes will be used as
backfill material.
The number of personnel to work at land preparation and construction stage will not
exceed 100 persons. The amount of domestic solid wastes to be generated by the
personnel concerned is calculated as follows by using domestic solid waste amount 0.865
BOZAT INC.
OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 15
kg value produced daily per person (State Statistical Institute (DİE), The Results of the
Survey on Environmental Statistics, Household Solid Waste Composition and Tendency
Questionnaire, 1993):
100 personsx0.865kg/person-day=86,5kg/day
In accordance with the Article 8 of the “Regulation on Control of Solid Wastes” enforced
upon publication in the Official Gazette dated 14.03.1991 and No. 20814, domestic solid
wastes to be formed will be collected separately, and necessary precautions will be taken
for the purpose of facilitating their disposal and use without damaging the environment,
preventing environmental pollution and contributing to economy. The principles mentioned
in the Article 18 in section four of the same Regulation regarding collection and
transportation of solid wastes will be complied with and solid wastes will not be dumped
into places where they will cause negative impacts on the environment and will be
collected in standard closed waste bins.
In line with the Article 20 of the same section, they will be carried and discharged to the
landfills shown by the Municipality in such a way as not to pollute the environment in terms
of such factors as appearance, smell, dust, leakage etc.
Since the excavation to emerge during land preparation will be stored for the purpose of
backfilling base and pits, landscaping works and asphalting processes of stabilized road,
there will be no excavation waste materials.
Waste management will be achieved in such a way as to minimize the negative effects of
waste oil, grease oil and fuel on human health and environment in line with provisions of
“Regulation on Control of Hazardous Wastes” enforced upon publication in the Official
Gazette dated 27 August 1995 and No. 22387 and the “Circulars on Oil Wastes and Waste
Oil” dated 12 August 1996 and No. 2440-5249 and dated 21 November 1997 and No.
4473-7756.
B. Operation Stage
In total, 5 personnel will work at the operation stage of the project. A social facility will be available inside the power house building for the personnel to be employed.
Domestic solid waste amount to be generated by the personnel assigned is calculated as follows by using the domestic solid waste amount 0.865 kg value produced daily per person:
BOZAT INC.
OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 16
5 N X 0.865 kg /N-day = 4,325 kg/day In accordance with the Article 8 of the “Regulation on Control of Solid Wastes” enforced
upon publication in the Official Gazette dated 14.03.1991 and No. 20814, domestic solid
wastes to be formed will be collected separately and necessary precautions will be taken
for the purpose of facilitating their disposal and use without damaging the environment,
preventing environmental pollution and contributing to the economy. The principles
mentioned in the Article 18 in section 4 of the same regulation regarding collection and
transportation of solid wastes will be complied with and solid wastes will not be dumped
into places where they will cause negative impacts on the environment and will be
collected in standard closed waste bins. In line with the Article 20 of the same section, they
will be carried and discharged to the landfills shown by the Municipality in such a way as
not to pollute the environment in terms of such factors as appearance, smell, dust, leakage
etc.
Waste management will be achieved in such a way as to minimize the detrimental effect of
waste oil and grease oil to be caused by maintenance and repair of tools and equipment
as well as the wastes formed as a result of leakage arising from fuel storage tanks and
petroleum pipelines on human health and environment in line with provisions of the
“Regulation on Control of Hazardous Wastes” enforced upon publication in the Official
Gazette dated 27 August 1995 and No. 22387 and the “Circulars on Oil Wastes and Waste
Oil” dated 12 August 1996 and No. 2440-5249 and dated 21 November 1997 and No.
4473-7756.
iii) Emission
A. Construction Stage
Catalytic heaters and electric energy will be used for the heating of workers who will work
beginning from land preparation until putting into operation of units and no fuel
consumption will take place for heating purposes.
Emission will generate as a result of the operation of construction equipments in the
activity area. Diesel oil will be used in construction equipments to be used in the area as
fuel and general properties of diesel oil are given in Table-2.d.3.

In accordance with this, the estimated pollutant values originating from construction equipments: Carbonmonoxides : 9,7 kg/T×0,052t/h=0,5044 g/h
Hydrocarbons : 29kg/Tx0,052t/h=1,508 kg/h
Nitrogen Oxides : 36kg/Tx0,052t/h=1,872 kg/h
Sulphur oxides : 6,5kg/Tx0,052t/h=0,338 kg/h
Dust : 18kg/Tx0,052t/h=0,936 kg/h
As mass flow values calculated for construction equipments is very low, it will not have any
negative impact on the current air quality.
Dust formation is expected during the construction activities of the project. Any kind of
solid or liquid substance, which has dimensions of a single molecule, is larger than
0.0002µm, smaller than 500µm and can suspend in the air for a while is in particle class.
Principles specified in the Article 7 of the Regulation on Protection of Air Quality enforced
upon publication in the Official Gazette dated 02.11.1986 and No. 19269 will be complied
with during transportation, unloading and loading of both excavation and excavation
wastes during the facility activity. Furthermore, principles in Section 5 of this article will be
complied with.
Approximately 30.000m3 (45.000 tons) of excavation waste material is expected to be
formed during land preparation. This material obtained will be stored to be used as backfill
material in the field and some of it will be used in road construction.
Dust emitting processes such as transport, loading and unloading will be used in
calculation of dust emissions due to the above-mentioned conditions. Dust emission
calculations will be carried out by considering that the whole excavation waste material
has been processed, which is the worst possibility.
Quantities of excavation waste material generation to be processed by working 10 months
in a year, 26 days in a month and 8 hours in a day and 3 years in total are given in Table-
2.d.5.
BOZAT INC.
OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 19
Table-2.d.5. Quantities of excavation waste material generation to be formed at the construction stage

1 month (26 days) 1.000 1.500
1 day (8 hours) 38,46 57,6
1 hour 4,8 7,21
Dust emission factors to be used in the calculation of dust emission formations are as
follows:
Transport (dust raised from roads) = 0,7 kg/km-vehicle
Loading of Material = 0,01 kg/ton
Unloading of Material = 0,01 kg/ton
*Dust amount to result from loading and unloading of material
- Amount of dust resulting from loading
7,21 ton /hour x 0,01 kg/ton = 0,072kg/hour
- Amount of dust resulting from unloading
7,21 ton /hour x 0,01 kg/ton = 0,072kg/hour
- Amount of dust resulting from loading and unloading
0,072kg/hour + 0,072kg/hour = 0,14kg/hour
* Amount of dust to be formed during transport of material:
BOZAT INC.
OSKAN Hydroelectric Power Plant EIA Preliminary Survey Report 20
The material obtained from excavation will be stored to be used in site grading works, road
construction and some of it will be used as backfill material in the field. Transport distance
will be approximately 1 km. Considering that a truck transports 13,5 tons of material at a
time, for 7,21 tons of material which will be produced in one hour:
7,21ton/hour / 13,5 ton/trip =0,5 trip/hour (1 trip will be completed in one hour)
In this case, the amount of dust to be formed during transport for one-hour production:
1 trip/hour x 1 km/trip x Q,7kg/km =0,7 kg/hour
Mass flow rate value of the dust to be formed in this case:
Q=(1)+(2)
Q2= 0,14 kg/hour + 0,7 kg/hour + =0,84 kg/hour
It is indicated in article 1.1. of Annex. 2 list of the Regulation on Protection of Air Quality
that “the values representing air pollution are values of contribution to air pollution obtained
by measurements and total pollution values that constitute these values”. This definition is
followed by the provision that “in the case that the emissions occurring in places other than
chimneys are lower than 10% of the values given in the table below, there is no need for
calculations of Value of Contribution to Air Pollution and Total Pollution Value” in
subparagraph (b) of the same article.
Mass flow rate given for dust emission in first line of this table is 15 kg/hour. 10% of this is
1,5 kg/hour. Emission factors were obtained from EPA (www.epa.gov).

Accordingly, as 0,84 kg/hour value is not above the 1,5 kg/hour value, which is the limit
value set out in the Regulation on Protection of Air Quality, and all operations will not be
carried out simultaneously, there was no need for air modelling.
The dust arising from the road will demonstrate a linear distribution and as the dust
amount formed remained below the 1,5 kg/hour value, which is the limit value set out in
the Regulation on Protection of Air Quality, there was no need for air modelling.

However, although the value remained below the limit value, the precautions listed in
article 7/7 of the Regulation on Protection of Air Quality will be taken:
- Top of transporters will be covered with canvases
- Running speed of vehicles will be low (40 km at maximum)
- Roads will be moistened continuously.
In addition, personnel working in borrow pits have to wear dust mask in line with the
Regulation on Occupational Health and Safety of the Ministry of Labour and Social
Security of Republic of Turkey. As it will be followed throughout the entire stages of the
project, the Regulation on Protection of Air Quality enforced upon publication in the Official
Gazette dated November 2, 1986 and No. 19269, the Regulation on Noise Control
enforced upon publication in the Official Gazette dated December 11, 1986 and No. 19308
and provisions of the Regulation on Occupational Health and Safety of the Ministry of
Labour and Social Security of the Republic of Turkey will be complied with during these
operations and no problems will arise in terms of human health and environmental health
in this context.
B. Operation Stage
Catalytic heaters and electric energy will be used for heating of workers who will work at
the operation stage of the project and no fuel consumption will occur for heating purposes.
No emissions will occur at the operation stage of the project.

iv) Noise A. Construction Stage
Vibration and noise will be generated by the use of heavy machinery and crusher facility -
even though it is used to a certain extent during the works to be conducted until the units
are put into operation. Machines will not work continuously, but in short periods. When the
noises to be generated at site are taken into account, the limits set for site noises in Table
4 of the “Regulation on Noise Control” enforced upon publication in the Official Gazette
dated 11.12.1986 and No. 19308 will not be exceeded. These limits are as follows:
Noise Source
Noise Level (Leq (dBA))
Building Construction (Continuous) 70
Road Construction (Temporary) 75
Impact Noises 100(Lmax)
All values contained in Annex: 1 of the regulation concerned will be observed as limit for
construction equipment and noises caused by construction equipment. For this purpose, it
will be ensured that the machines to be used are new and high-quality products of state-of-
the-art technology.
With regard to the noise that can be generated in the facility, the provisions contained in
the “Regulation on Noise Control” enforced upon publication in the Official Gazette dated
11.12.1986 and No. 19308 will be complied with. It is stated in the Article 6 of the second
section of this regulation pertinent to industry, road and construction machinery that
operation, putting into service and use of various noise sources and vehicles that create
the maximum noise permitted to be emitted by these sources is prohibited. It is indicated
that operation, putting into service and use of vehicles, the sound levels of which are given
in Annex 1 and which emit higher levels of noise than
