The impact area of Kesme Regulator and HEPP Project, during construction and operation periods is identified by the concurrent evaluation of the impacts, which may occur in the settlement near regulator axis and around HEPP construction, on environmental, economical and social aspects. The construction stage will not have a negative impact for the natural life in settlements surrounding the regulator axis. The project is a power plant with reservoir and it is anticipated that 320.000 m2 land will be flooded. However, there are no settlements on the land that will be included in the reservoir.


The tunnels planned to construct in the project will be opened by means of loosening blastings when required. Ventilation will be installed to prevent the staff working inside the tunnels from being affected by the dust. The dust occurring due to the loosening blastings inside the tunnel will not spread since it will precipitate in the tunnel.

During 24 months of period starting from the construction of Kesme Regulator and HEPP project planned by KIVANÇ Enerji until the completion of construction, 100 persons are planned to be employed as demonstrated in the workflow chart.


During the operation activity that is anticipated to begin following the completion of the construction, directly 10 persons are estimated to be employed permanently and the staff requirement will be principally provided from the nearby villages.
Employment opportunities will be available for the local communities at the construction and operation stages of the project. Moreover, most of the social needs of the staff will be supplied from the nearby settlements and those activities as well will create an additional income for the local communities.
1.b) Use of Natural Resources (Land Use, Water Use, Used Energy Type etc.)
22.810 hectare area in total are irrigated in Narlı and Kahramanmaraş Plains by Kartalkaya Dam, which was constructed on Aksu creek located in the 5 km northwest of Pazarcık district in Kahramanmaraş province and was taken into operation in 1971. Additionally, the water is delivered for drinking, utility and industrial water demand of Gaziantep province. Kesme Regulator and HEPP project are located in the upstream of existing Kartalkaya Dam. After the waters are used through Kesme Regulator and HEPP project, they will be discharged into the existing Dehliz Regulator regulating the irrigation waters in the downstream. Sır Enerji project hydroelectric power plant having an installed power of 8 MW, which was developed by the private sector and is under construction, is located at the slope of Kartalkaya dam as bottom power plant. Energy generation is planned with the waters delivered for irrigation or sluiced waters from Karakaya dam by Kesme Regulator and HEPP project. It will be constructed and operated in a way not to hinder Dehliz regulator and irrigation.
Kesme Regulator and HEPP project is a plant with reservoir. It is anticipated that approximately 320.000 m2 land will be flooded by Kesme Regulator and HEPP Project. However, there are no settlements on the land that will be included in the reservoir. This plant will generate energy with the waters delivered for irrigation or sluiced waters from Kartalkaya dam and it will be constructed and operated in a way not to hinder Dehliz regulator and irrigation.
Water usage within the scope of Kesme Regulator and HEPP Project is not in question. HEPPs are not water consuming plants. The same amount of water treated through the turbines for electricity generation will be returned into the riverbed. 100 l/h water will be discharged for the continuity of living species and ecosystem.
In the scope of the project; 4,300 m3 excavation will come out during the construction of regulator, water intake structure, etc., 15,615 m3 during transmission canal, 1,990 m3 during forebay, 9.90 m3 during penstock and 1,820 m3 during HEPP building and tail water canal. The total excavation to be formed is 23.734,9 m3. Aggregate materials that will be required at the construction of engineering structures in the scope of Kesme Regulator and HEPP project are around 30.000 m3.

It is considered that 50% of the excavation materials that will be generated during the construction activities, will be converted to the appropriate sizes at the crushing-screening plant and then will be utilized for concrete production and the rest will be utilized either as backfill material for the roads constructed/rehabilitated or during the rehabilitation of the equipment area. The rest of the required aggregate material will be supplied from 2 borrow pits. The vegetative soil obtained during the excavation will be stored under suitable conditions in the area of the unit to be excavated or nearby, and will be used in the rehabilitation and/or landscaping activities.


2 material sites demonstrated on the topographical map in the Appendix 1 are designated as borrow pit locations and one is close (50 m distance) to the power plant location and the other is to the regulator location. Sand-pebbles available in those sites have the characteristics to meet the demands in terms of both quantity and quality.
Electricity energy will be needed at all stages of the project. The project itself is a project intended for electricity generation and part of the energy demand at the construction stage will be provided by the existing substation and the other part by generators.
The major water usage at the construction stage of the project will be for concrete production, prevention of dust emission and drinking-using water of the staff. The water necessary for concrete plant and prevention of dust emission will be supplied from Aksu creek. Drinking and utility water will be supplied from the spring waters existing near the construction site to be installed. The domestic water demand of 100 persons that will be working at the construction stage as a result of the calculations made is as follows;
Qdomestic = 100 N * 0.150 m3/N*day = 15 m3/day
In the same way, 50 m3 water for washing the concrete aggregate material and concrete mixers and approximately 2,000 m3 water in total during the project period for concrete production will be required. The amount of water to be used in addition to the measures applied to prevent the dust emission occurring during the construction activities may change depending on the surface geometry of the material to be transported, meteorological conditions of the environment before and after watering and topographic condition of the land to be excavated.
There will not be any use of the natural resources except those mentioned during the activity.
1.c) Amount of Wastes Generated (Solid, Liquid, Gas etc.) and Chemical, Physical and Biological Characteristics of the Wastes
The waste and environmental impacts listed below in headings are expected to occur at the construction and operation stages of Kesme Regulator and HEPP project. Any solid, liquid and gas waste and emissions are not expected to generate after the activity is closed for operation.



  1. Amount of Wastes Generated at the Construction Stage and Chemical, Physical and Biological Characteristics of the Wastes

I.I Solid wastes:
Wastes that will be generated at the construction stage of the planned activity will consist of excavation resulting from excavation works, construction iron, wood wastes used for formworks, packaging materials and similar solid wastes. Among those wastes the recyclable materials such as iron, steel, metal and similar will be collected separately from the other wastes and will be sold as scrap. Formwork wood wastes to be formed will be collected in specific time intervals. Collected wood wastes will be delivered to the surrounding villagers if there is any demand. Non-recyclable wastes will be collected in the closed waste bins and will be disposed to the solid wastes disposal area of the Municipality of Pazarcık.
100 persons from different occupational groups will work at site arrangement and construction stages. The amount of domestic solid waste to be generated by the staff is expected as follows based on 1.34 kg value;
100 persons * 1.34 kg/person*day = 134 kg/day
The amount of domestic solid waste produced at the construction stage of the project is calculated as 134 kg/day and the “Regulation on Control of Solid Wastes” enforced upon publication in the Official Gazette dated 14.03.1991 and No. 20814 will be complied with regarding those wastes.
It is considered that 50% of the excavation materials that will be generated during the construction activities (23,734.9 m3), will be converted to the appropriate sizes at the crushing-screening plant and then will be utilized for concrete production and the rest will be utilized either as backfill material for the roads constructed/rehabilitated or during the rehabilitation of the equipment area. The vegetative soil obtained during the excavation will be stored under suitable conditions in the area of the unit to be excavated or nearby, and will be used in the rehabilitation and/or landscaping activities. The amounts of excavation to be conducted are presented in Table 4 below in the light of the data of Kesme Regulator and HEPP revised feasibility report.
I.II Waste Oils:
Oil changes of the heavy equipment and cars to be utilized during the project will be performed in every 200 hours. Since the works will be carried out for 8 h/day and 26 days/month and vehicle oil changes will be performed periodically in the licensed gas stations, there will not be any waste oil formation originated from those vehicles.
I.III Wastewater:
The major water usage at the construction stage of the project will be for concrete production, prevention of dust emission and drinking-using water purposes for the staff. The water necessary for concrete plant and prevention of dust emission will be supplied from Aksu creek. Drinking and utility water will be supplied from the spring waters existing near the construction site to be installed. The domestic water demand of 100 persons that will be working at the construction stage as a result of the

Calculations made is estimated to be 15 m3. In the same way, 50 m3 water for washing the concrete aggregate material and concrete mixers and approx 2,000 m3 water in total during the project period for concrete production will be required. The amount of water to be used in addition to the measures applied to prevent the dust emission occurring during the construction activities may change depending on the surface geometry of the material to be transported, meteorological conditions of the environment before and after watering and topographic condition of the land to be excavated.

As a result of those activities; wastewater will be produced from the employees and due to washing of the mixers included in the concrete plant, vehicle mixers transporting the concrete and concrete aggregate to be used for concrete production. Considering that all the daily water demand of the staff is converted into domestic wastewater at the construction stage, daily produced domestic wastewater amount will be 15 m3. As a result of concrete aggregate and washing of mixers, 50 m3 wastewater with high suspended solid content will be generated.

Domestic wastewaters generated by the staff will be collected in the cesspool that will be drilled in a suitable spot and of which tightness to the underground will be maintained through proper techniques, and it will be periodically discharged to the system where the municipality discharges the sewerage after vacuuming the cesspool with sewage trucks. Provisions of the Article 25 of the Regulation on Control of Water Pollution will be taken into account on this issue. The dimensions of the cesspool tank that is planned to be constructed is determined as 5*5*3 = 75 m3 in the context of the Regulation on the Pits to be excavated where Sewer System Construction is not Possible enforced upon publication in the Official Gazette dated 19.03.1971 and No. 13783. Moreover, the provisions of the Regulation on Control of Water Pollution enforced upon publication in the Official Gazette dated 31.12.2004 and No. 25687 will be complied with on this issue.
Wastewater generated from the washing of concrete aggregate material and concrete mixers will be reused for washing of concrete aggregate material and concrete mixers processes after being treated in the sedimentation pool planned to be constructed. The provisions of the Regulation on Control of Water Pollution enforced upon the Official Gazette dated 31.12.2004 and No. 25687 and Fisheries Law No. 1380 will be complied with on this issue.
I.IV Air Pollution and Emissions:
Temperature, pressure and wind play an active role on air pollution transport. In this regard, the meteorological data from the Meteorological station of the Kahramanmaraş Province, which demonstrate the project site at most, are presented below.
According to the annual data of this station, the average annual maximum temperature in the district is 44.3 0C, and average annual minimum temperature is -9 0C. The limit air temperature data of the region and other meteorological elements are presented in Table 5.
As a result of the measurements taken in the region by the Turkish State Meteorological Service, annual blowing wind numbers and directions are demonstrated in detail in the below graphic.

As a result of the measurements taken in the region by the Turkish State Meteorological Service, annual blowing wind numbers and directions are demonstrated in detail in the below graphic.



The Province of Kahramanmaraş, where the project will be realised, is among the cities facing the air pollution on the first degree. The primary reason for this is wood and coal used for heating during the winter season. And the traffic is the second reason for this. According to the data provided by the Environmental Status of the Province of Kahramanmaraş there are 96,500 vehicles registered at the provincial traffic registry.
