SECTION V: THE IMPACTS OF THE PROJECT ON THE REGION DEFINED IN SECTION IV AND THE PRECAUTIONS THAT WILL BE TAKEN In this section, the impacts of the project on the physical and biological environment are defined. Legal, administrative, and technical precautions that will be taken to mitigate and alleviate these impacts are explained for both the preparation, construction and installation phase and the operational phase separately and in detail. First, the activities during the land preparation, construction and instalment phase, the impacts on the physical and biological environment and the precautions that will be taken are explained. Information is given regarding where the excavations and how much excavation will be done within the scope of works to be done to prepare the land; and the usage, transport and storage of inflammable, explosive, dangerous and toxic materials to be used during excavation. It is calculated that the total amount of excavated material during the construction phase will be 11,817 m 3. This excavated material will not be transported somewhere else; but will be used in the environmental and landscape design, and in the correction of degraded lands in the region, depending on the inclination. The total dust emission is calculated as 0.4104 kg/hour. This is below the legal threshold of 1 kg/hour; and so an acceptable value. The solid domestic waste amount is calculated as 26.8 kg/day for the construction phase; and 6.7 kg/day for the operational phase. The total wastewater amount is calculated as 4 m 3 /day for the construction phase; and 1 m 3 /day for the operational phase. 5
The grounding works and lightning rod instalment are mentioned. The effect of noise for the land preparation, construction and instalment phase is evaluated using noise models. The nearest settlement to Mordoğan Wind Energy Plant is Mordoğan Town, which is located at 600 meters south-east. There is a residence belonging to Mordoğan town at approximately 350 meters away from the project area. According to the calculations, the noise level remains below the limit value set out in the Regulation on Assessment and Management of Environmental Noise as of 100 meters. Since duty machines shall not be operated simultaneously and since the noise sources are not fixed tools, the noise level shall remain below the calculated value. Therefore, the noise to come into existence during the activity shall have no adverse effect on the residential units. Other activities that will done during the land preparation, construction and instalment are also evaluated in terms of their effects on the physical and biological environment. No significant potential negative impacts could be found. All the potential impacts that could be specified are within the acceptable range defined by the legislation. The potential impacts of the project for the operational phase are also evaluated in the EIA Study and mentioned in the report. The maintenance affairs of the wind farm is discussed. The main issue regarding the maintenance of the wind turbines is the annual periodic change of the gearbox lubricant oil. The waste oil will not be stored and will be taken away according to the regulations. Waste oil treatment will be done strictly in line with the corresponding legislation. All the necessary precautions will be taken to prevent any potential oil leakage. Electromagnetic impacts of the wind turbines are also examined. Electric and magnetic fields that will be produced by the wind turbines are evaluated. With reference to the up-to-date and the most recent scientific research findings related to this field, it is concluded that the electromagnetic effects of the project can only be considered significant only for the locations very near to the turbines; and in general and for normal distances, the overall electromagnetic impacts are minimal and within acceptable range. Light reflection and shadow flicker effects are also discussed. To minimize light reflection, the turbines are dyed with light dull grey colour in line with the international standards. No shadow flicker effects could be found. The impacts on the bird life is examined in an ornithological study contained in the EIA and found to be minimal and acceptable. The effect of the project on the communicational facilities like telephone lines, radio and TV transmitters are also evaluated and found to be significant only for places very near to the turbines. No potential negative impacts of the project on the forest land could be found. The procedures related with the firefighting will be done according to the relevant legislation. The noise impact of the project activity during the operation is also evaluated by using models. The nearest settlement to Mordogan Wind Farm is Mordogan Town, which is located at 600 meters southeast. There is a residence belonging to Mordogan town at approximately 350 meters away from the project area. The noise level remains below the limit value set out in the Regulation on Assessment and Management of Environmental Noise as of 500 meters. Therefore, the noise to come into existence during operation shall have no adverse effect on the residential units. Provisions of the "Regulation on Assessment and Management of Environmental Noise" of 04.06.2010 No. 27601 shall 6
be obeyed at the operation stage of the project. Therefore, the noise to come into existence during operation shall have no adverse effect on the residential units. Hence, the noise level is within the acceptable range. A short cost-benefit analysis is done for the wind turbines in general, and wind power plants are found to be favourable. SECTION VI: THE IMPACTS THAT MAY HAPPEN AFTER THE OPERATION HAS STOPPED AND THE CONTINUING IMPACTS, AND PRECAUTIONS THAT WILL BE TAKEN AGAINST THESE The lifetime of the project activity is specified as 25 years in the EIA Study. The equipment having completed their lives will be renewed and put into operation. When the project activity has been terminated, all the turbines and towers will be dismantled and area that has been covered by the turbine towers will be converted to its natural state. SECTION VII: PROJECT ALTERNATIVES In this section, the possible alternatives of the project are compared with reference to location selection, technology, and the precautions that will be taken. An order of preference is made for these alternatives. The dependence of Turkey on fossil fuels in electricity generation, and inadequacy of hydroelectric power to compensate this is emphasized. The pros and cons of the wind power technology are discussed and it is concluded that wind power is the best alternative among the electricity generation technologies available in the region. SECTION VIII: MONITORING (FOLLOW-UP) PROGRAMME In this section, the monitoring programmes proposed for the constructional, operational, and postoperational phases are introduced. The bylaws related with the electrical installations, noise, solid wastes, water pollution, air pollution, and occupational health and safety are mentioned. The precautions and measures stated in the previous chapters for environmental, economic and social aspects are summarized. Emergency Response Plans for Occupational Accident, Fire and Earthquake are shown in in detail in figures. In brief, it is stated in this chapter that all the necessary precautions and measures shall be taken to eliminate or minimize all the potential negative effects of the project within the scope of the relevant legislation. SECTION IX: PUBLIC PARTICIPATION In this section, it is stated that a public participation meeting has been held in order to inform the local people in the project area region and to receive feedbacks. It is mentioned that no negative feedback has been taken. 7
