The WWTP planned to be constructed in the scope of the Project has been designed in two stages. Target years of these two stages are 2021 and 2041. When domestic and industrial wastewater flow is considered, equivalent population values in these years for the designed WWTP are 78,232 and 125,171, respectively. Also, predicted flow values for these years are 180.59 L/sec and 328.31 L/sec respectively. A Sewage Network Project Preliminary Survey Study had been conducted by Beypazarı Municipality in 21.07.2006. According to that study, it is planned to build new collector lines to existing sewage system, in order to get wastewater to treatment plant. There will be 3 pump stations with the aforementioned collector line. Treatment Plant’s Final Project Design has been approved on September 2007 whereas Collector Lines’ Final Project has been approved on November 11, 2011. Project will be financed with Municipality’s own resources and the credit to be supplied in the scope of “Municipal Services Additional Financing Project” that is undertaken in the context of the credit agreement signed between the World Bank (WB) and the Bank of Provinces (BoP). According to Operational Policies (OP) 4.01, projects are considered in two categories with respect to the magnitude of their environmental impacts. Projects with possible severe impacts are considered in Category A whereas projects with low impacts are considered in Category B. According to the document called “Environmental Framework”, produced in the context of Municipality Services Project of BoP, WWTP projects are listed in Category A. Therefore, Environmental Impact Assessment (EIA) Report in accordance with the format given in Annex B to OP 4.01 needs to be prepared for these projects. Turkish Environmental Impact Assessment (EIA) Regulation was revised in July 17, 2008. According Annex I of new EIA regulation which presents a list of the project that requires the preparation of an EIA Report, the wastewater treatment plants having a capacity more than 30,000 m3/day requires an EIA Report. Therefore, under national EIA Regulation the Project does not require an environmental assessment. This EIA Report, prepared for the proposed Project, defines the area where the Project Site is located and environmental and socio-economic baseline data is provided for this area. It provides assessment of likely environmental impacts that may be the result of Project activities as well as mitigation measures to be taken so as to minimize these impacts. These mitigation measures and the monitoring program, prepared for the assessment of the environmental performance of the Project, are presented in the Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 1/62 Environmental Management Plan. A summary of the mitigation measures and monitoring plan is given in the following paragraphs. Vegetative soil of the excavated material stripped from the site will be separately stored in order to be used in landscaping works at the final stage of the construction. According to site ecological studies and literature survey carried out for the Project Site and its vicinity, there are no endangered flora and fauna species in the vicinity of the Project Site. As a result of quantitative assessment of dust and noise to be generated during construction and operational phases, it has been determined that there will be no adverse impacts of dust and noise on the people living in the nearest settlement, i.e. a house near the site. Nevertheless, measures will be taken in order to reduce dust emissions. These measures include careful handling of excavation material and watering of roads in dry and windy weather conditions. Also there will be a limitation on truck speed (i.e. 30 km/h of maximum speed) on unpaved roads. During construction phase there will be monthly dust and noise measurements at the nearest house in order to monitor the actual impacts of the project activities. Monitoring of noise will continue in the operational phase according to complaints from the public in the nearest house. In addition to this, dust and odor will be monitored by qualitative assessment which will be conducted through interviewing local people. As per the general waste management procedures to be followed during construction and operational phases of the project, domestic solid wastes will be disposed of in the current dump site until the new landfill, which is planned to be constructed by the union of municipalities, becomes operational. Treatment sludge, during the operational phase of the Project, will be sent to Tatlar Wastewater Treatment Plant of Ankara Metropolitan Municipality located in Sincan. In construction phase, domestic wastewater will be treated in the package treatment plant, and discharged to Inozu Creek after necessary discharge permit will be obtained from the Ankara Provincial Directorate of Environment and Urbanization (PDoEU) whereas in operational phase, domestic wastewater will be treated at the WWTP and then discharged into Inozu Creek. In operational phase, discharged wastewater quality will be monitored according to frequencies set in the Notification on Sampling and Analysis Methods of the Water Pollution Control Regulation. Inozu Creek joins Kirmir Creek in the south which finally discharges into the reservoir of Sariyar Dam. Therefore, Inozu Creek is considered to be one of the branches for Sariyar Dam. Hazardous waste to be generated in both phases such as waste oil, empty paint boxes and used fluorescent lamps will be temporarily kept in storage areas constructed with Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 2/62 certain protection measures before they are given to firms licensed by the Ministry of Environment and Forestry (MoEF)1 for collection of hazardous waste. There will be barriers and warning signs around the construction site in order to prevent entry of local people into the site. There will be also warning signs on the highway side in order to warn drivers about trucks entering or leaving the site. In addition, there are no known sites or assets which would be affected by the Project, as for the protection of cultural assets, construction works will be stopped immediately in case of a coincidental finding in the Project Site. The relevant museum directorate will be subsequently notified. Construction activities will continue according to provisions of the museum directorate. It should also be noted that Sariyar Dam Reservoir is located at the downstream of Beypazari District, and therefore, it is subject to a serious pollution due to discharge of untreated wastewater from the district. Sariyar Reservoir is a wetland but does not have protection status such as environmental protection area, Ramsar site, etc. However, wetlands in Turkey are considered within provisions of “Regulation on the Conservation of Wetlands” which is restricting some developments in the vicinity of the area such as industrial facilities, etc. 1 It has been established as T.C. Ministry of Environment and Urbanization and it is published in Official Gazette dated July 04, 2011 and numbered 27984. The duties of T.C. Ministry of Environment and Forestry have been transferred to T.C. Ministry of Environment and Urbanization.

Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 5/62 3 PROJECT DESCRIPTION 3.1 Objectives of the Project Municipality aims to realize Beypazarı WWTP Project for treatment of domestic wastewater in district center as well as industrial wastewater generated by industrial establishments within the borders of the district. 3.2 In the scope of the project, besides WWTP, there will be new collector lines and pump stations for these collector pipes. Current Situation The domestic and industrial wastewater generated in Beypazarı District is collected by the sewerage system and discharged to Inozu River. Sewerage system has 4 existing discharge point. One of these is 500m above WWTP Project area, has Ø400 mm length in diameter and making its discharge to Karapınar Creek. Wastewater that coming from Oğuzkent district, which is in east part of Beypazarı, discharges with a Ø300 mm line to Azmak Creek. The wastewater that coming from east part of Beypazarı whe re is in northern part of Oğuzkent, connected to Ø200 mm line with Akyazı pumping station and this line is connected to Ø400mm collector line. Another discharge point is at Bağırsak Creek. This line has Ø300 mm in diameter and collects wastewater of Boztepe district. Last and fourth existing discharge point is at Beykent Creek. With a Ø300 mm collector line, Aşağıbaşağaç district’s wastewater discharging to that point. In Beypazarı, the existing industrial activities are: agricultural production trades, fodder factory, farm business (on milk), flour factory and carpenters. Another project is undertaken by the Municipality to rehabilitate and extend the sewerage network in the district center. This project is also financed with Municipality’s own resources and by the support of Ankara Metropolitan Municipality. “Rehabilitation and extension of the sewerage network” Project has been completed which is supported by Ankara Metropolitan Municipality. Therefore, this project is ready for the connection to the collector lines to be constructed with the WWTP. In this context, construction of sewage collection line and wastewater treatment plant will be started simultaneously. In the scope of this sewerage rehabilitation and extension project, a pipeline is planned to connect the sewerage system to the WWTP. There is no risk that the WWTP is not receiving the wastewater after its completion. 3.3 Importance of the Project The Project aims to eliminate or minimize the adverse environmental impacts caused by the discharge of wastewater to the receiving environment without treatment. These environmental impacts are listed below,  Pollution in Inozu Creek and other surface water resources which Inozu River joins;  The soil pollution due to irrigation with polluted surface water; Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 6/62  Groundwater pollution due to transportation of surface water pollutants and subsequently worsening of public health;  Deterioration of the ecological system and biodiversity in polluted surface water resources. 3.4 Characteristics of the Project Final design work of the Project has been conducted and then approved by BoP as the name of “Beypazari WWTP Final Design Report” in September 2007. Information given in this section has obtained from the Beypazari WWTP Final Design Report Construction of the WWTP has been planned to be completed in two stages. First stage is designed according to the equivalent population (calculated considering both domestic and industrial wastewater flow) of the year 2021, and the second stage will handle the domestic and industrial wastewater generated in the year 2041.

Detailed information about the calculation of the flow is given below. i. Calculation of Domestic Flow: Together with the population of Beypazarı, (i) number of the students in educational institutions and (ii) the effects of the touristic facilities are also considered in domestic flow calculations. For the first stage of the WWTP, population of 2021 is 64,100 and for the second stage of the WWTP, population of 2041 is 105,100. Per capita water flow is taken as 120 L/cap- day for the first stage and 135 L/cap-day for the second stage. For the calculation of domestic flow, it is assumed that 80 percent of the consumed water turns into wastewater. According to this assumption, calculated flow values are 6153.6 m3/day and 11,340 m3/day for the years 2021 and 2041, respectively [1]. Wastewater Flow from Educational Institutions There are two vocational schools with a total number of 500 students in Beypazarı. Growth rate for the number of students is accepted as 1% per year. So there will be 580 and 1008 students in 2021 and 2041, respectively. Also, a dormitory with a capacity of 300 students is planned to be built. Flow generated in the dormitory included in flow calculations for 2nd Stage. Hence, wastewater flow for the first stage will be 55.68 m3/day, and it will be 108.86 m3/day for the second stage [1]. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 8/62 Wastewater Flow from Touristic Facilities Wastewater flow from (i) touristic facilities, (ii) one-day tourists and (iii) thermal facility have been considered in calculating the total wastewater flow due to touristic activities. There are approximately 400 beds in the touristic facilities in Beypazari. In final design studies it is assumed that population (the number of beds) in these facilities will grow at a growth coefficient of 3.00 until 2021, and population will stay the same after 2021. Unlike other domestic wastewater flow calculations, wastewater consumption in touristic facilities is taken as 175 L/cap-day. This value has been selected from the range of 100-250 L/cap-day that was determined by the BoP. Hence, number of beds in 2021 will be 642 while wastewater flow will be 89.9 m3/day [1]. According to figures of the year 2005, the number of one-day tourists is 2564. The bed capacity of the touristic facilities, 400, was subtracted from this figure. Hence, increasing at the rate of 3.00, the number of tourists, 2164, is expected to reach 3473 in 2021. Number of tourists is assumed to stay the same for the coming years. It is assumed that water consumed by tourists is 20 L/cap-day, and wastewater generation is calculated as 55.63 m3/day [1]. A thermal hotel with a capacity of 4000 is planned to be erected. It is assumed that number of beds filled in the year 2021 and 2041 is 2000 and 4000, respectively. Wastewater flow rate calculated for the two stages is 320 m3/day and 640 m3/day, respectively [1]. Total domestic wastewater flow for the two stages is calculated as 6674.78 m3/day and 12,234.36 m3/day, respectively [1]. ii. Calculation of Industrial Wastewater Flow There are various industrial plants in Beypazarı. These are mainly comprised of milk and dairy products, mineral water and ready-mixed concrete.

Although there has been also carpet business in addition to these industrial facilities in the Beypazarı District carpet business has not been mentioned in the Table 3-2. These facilities have been ignored in the flow rate calculations, since carpets have been weaved at the handloom by carper weavers. Hence, it has been estimated that carpet business has not produce any industrial wastewater. iii. Infiltration Flow Infiltration flow is assumed 0.02 L/sec-ha in the Final Design Report. Project site is calculated as 750 ha for the first stage in 2021 and 1700 ha for the second stage in 2014. Infiltration flow calculations are given in Table 3-3 for each stage of the Project.

Industrial Pollution Load Calculated industrial pollution load in the Final Design Report has two components which are slaughterhouse and industrial plants except for slaughterhouse. Considering BOD5 pollution load for industrial plants, equivalent population is calculated. BOD5 pollution load is taken as 32 gr/cap-day and 37 gr/cap-day for both stages, respectively, in the calculation of equivalent population. According to this data, calculated pollution loads for industrial plants and equivalent populations are shown in Table 3-7.

Industrial Facilities in the Beypazarı District show similar characteristics with respect to their pollution load. Only the pollution load of slaughterhouse is indicated different properties when it is compared to those of other industrial facilities. Hence, facilities showing almost same pollution load characteristics are considered as a same group of Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 11/62 wastewater source. On the other hand, slaughterhouse is thought as another wastewater source. Pollution loads calculated based on equivalent population are given in Table 3-8.

These calculated flow values are compared to flow values measured between February 17-19, 2007 in order to check validity of the assumptions made in flow calculations [1]. According to the flow measurement results, three day average flow was calculated as 9,360 m3/day. This value is higher than calculated flow value. It is expected that this can be due to infiltration to the sewerage network. Present sewerage system will be rehabilitated in the scope of the new sewerage network project which will be realized by the Municipality. This will decrease the infiltration flow. Considering this, it has been decided that calculated flow values are more suitable to be used in the design of WWTP [1]. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 12/62 In addition to this, samples taken from discharge point to Inozu Creek have been analyzed. Sample analysis results are given in Table 3-10 and Table 3-11.

According to the WWTP Project Final Design Report, the main reason for the difference between two analysis results is that industry was active and small number of tourists was visiting Beypazari on 20.02.2007 [1]. 3.4.4 Population Projections Population projection for designing the WWTP has been carried out using data obtained from the results of population census conducted between 1940 and 2000. This data is shown in Table 3-12. Table 3-12 Population Statistic for Beypazarı at 1940-2000 Year* Population Population Growth Rate (%) 1940 5,268 - 1945 5,357 0,34 1950 5,913 1,99 1955 7,419 4,64 1960 8,854 3,60 1965 9,860 2,18 1970 12,830 5,41 1975 14,963 3,12 1980 16,971 2,55 1985 21,672 5,01 1990 26,225 3,89 2000 34,441 2,76 * Population census conducted in 1997 includes erroneous results, hence it is not considered in the calculations. Reference: Beypazari (Ankara) WWTP Final Design Report, 2007. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 13/62 By using this population data, population projection was made for the service period of the project ending in 2041. Population projection has been made using different methods including (i) population growth coefficient method, (ii) BoP method, (iii) arithmetic growth method, (iv) geometric growth method and (v) compound interest method. In the population projection carried out using BoP method, growth coefficients (GC) have been calculated for different periods between 1940 and 2000. These periods have been selected in a way that each one of them ends in 2000, and starts with a year in which a population census was conducted (e.g. between 1990 and 2000, 1985 and 2000, etc.). A GC has been calculated for each of these periods, and three different projections have been made using minimum (2.76), average (3.36) and maximum (3.64) values of GC. In addition to these, a population projection based on the population growth rate in Turkey has been made, and average of the results of different projections has been calculated [1]. Results of population projections are given in Table 3-13.

While population growth rate values calculated for the period between 1940 and 2000 varies between 0.34 and 5.41% (see Table 3-12), GC calculated for BoP method, i.e. 3.36, is larger than 3.00. GC calculated for the period between 1980 and 2000 fell from 3.60 to 2.76. As can be seen here, number of inhabitants of Beypazari is decreasing although the district is visited by many tourists [1]. Considering this, GC has been decided to be taken as a smaller value. GC was taken as 3.00 until 2021, and as 2.50 afterwards. Population estimates for the period between 2000 and 2041 which have been used for the design of the WWTP are presented in Table 3-14.

Phosphorous and nitrogen treatment is required to be accomplished by advanced treatment if there is an eutrophication risk in the receiving environment. There is also another notification called Urban Wastewater Treatment Regulation of Sensitive and Less Sensitive Areas (OG dated 27.06.2009 and numbered 27271). In this notification, sensitive and less sensitive regions of Turkey have been determined and discharge criteria of these areas have been given. However, İnözü Creek is not one of these regions. Hence, in this report, calculations have been done according to the Urban Wastewater Treatment Regulation. Currently, untreated wastewater is discharged into Inozu Creek. Constructing WWTP is a protective measure imposing removal of nitrogen and phosphorus which helps to prevent possible eutrophication. Treated wastewater in Beypazarı WWTP shall not exceed the limit values stipulated in the related regulations. This limit values are shown in Table 3-15.

Therefore, these values show compliance with each other. 3.4.6 Technology As mentioned before, Beypazarı WWTP has been designed to include two stages. Target years of these two stages are 2021 and 2041, respectively [1]. Treated wastewater will be discharged to Inozu Creek. This creek discharges to the reservoir of Sariyar Dam. According to State Hydraulic Works, usage purpose of Sariyar Dam is to produce energy with a power of 160 MWe. Due to wastewater discharge, there is a risk of eutrophication of this reservoir. Therefore, according to the regulation, advanced treatment, which ensures removal of nitrogen and phosphorous, is necessary. This has been taken into account in the design of WWTP. Main units of the WWTP are given below.

Information regarding units of the treatment process is presented below. Pretreatment Unit Pretreatment unit includes coarse and fine screens and aerated grit and grease chamber. Coarse Screen Coarse screen has been designed to block branches, residue, animal carcasses, packages, bottles etc. These materials will be kept at the coarse screen in order to prevent them from damaging the pumps. Solid waste to be kept at the coarse screen will be conveyed to a container via conveyor belt and then it ıs sent to Municipality’s current solid waste dump. Fine Screen Fine screen functions to prevent such fine materials in the wastewater as stone, fabrics, wood from being entering into downstream units. Fine screen has been designed as mechanically-raked, and materials kept at the screen will be conveyed to a container. Aerated Grit and Grease Chamber In this unit, such heavy inorganic materials as grit and gravels will be settled while oil and grease within wastewater will be removed. This unit has been designed to allow inorganic materials to settle down whereas organic materials, which will be removed in biological treatment, to float. In order to achieve this, horizontal velocity at the maximum flow rate is determined to be lower than 0.2 m/s. Grease removing equipment to be installed in the sides of this unit will remove oil and grease in wastewater. Transfer of wastewater from grit chamber to grease chamber will be through lamella separator. Grit removed in the grit chamber will be pumped to grit separators whereas grease removed in the grease chamber will be pumped to grease pits and send to the licensed companies. Biological Treatment Units Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 18/62 As mentioned in the previous sections, WWTP has been designed to ensure removal of phosphorus and nitrogen. Biological treatment unit is composed of two types of tanks. One of these is anaerobic tank while the other one is “Caroussel” type aeration tank, which includes anoxic and aerobic zones together. Due to the nature of the treatment process, complete mixing of the wastewater flowing into aeration tanks should be provided with mixers whereas oxygen will be supplied by blowers. Phosphorus Removal In order to remove phosphorus compounds in the wastewater an anaerobic medium (anaerobic tank) will be formed at the beginning of the biological treatment unit. In the anaerobic tank, dissolved carbonaceous compounds (BOD) will be mixed with recycled sludge in order to let polyphosphate-containing microorganisms hydrolyze polyphosphate, and uptake carbonaceous compounds into its body. In this process, phosphate is hydrolyzed, and converted into inorganic phosphate. This increases the concentration of dissolved phosphate in wastewater. In the aerobic section of the aeration tank, microorganisms oxidize the carbonaceous compounds that they have absorbed, and remove the phosphorus in wastewater. Nitrogen Removal In addition to biochemical degradation of carbonaceous compounds, organic nitrogen compounds are oxidized to nitrite and nitrate, respectively, in the aerobic section of the aeration tank. Denitrification process takes place in the anoxic section. In the denitrification section, biochemical degradation of carbonaceous compounds is not at high level. Therefore, outlet of the nitrification section will be connected to the inlet of the anoxic section. Sludge with high phosphorus content will be produced while BOD, phosphorus and nitrogen is removed. Secondary Sedimentation Tanks Wastewater to be treated in aeration tanks will flow into secondary sedimentation tanks. Supernatant in secondary sedimentation tanks will be discharged into the receiving environment. In order to increase the efficiency of the treatment process, some part of the settled sludge will be returned to the inlet of the biological treatment via sludge recycle line. Secondary sedimentation tanks will be constructed in circular shape. Wastewater flowing into sedimentation tanks will be distributed evenly via pipes. Sludge Dewatering Solid matter content in the sludge at the outlet of the sludge-dewatering (decanter)will be between 18 and 22%. Cationic polyelectrolyte will be dosed into sludge as a sludge conditioner. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 19/62 3.5 Utilization of Natural Resources (Utilization of Land and Water Resources and Type of Energy Utilized etc.) Information about the utilization of the natural resources is given below. 3.5.1 Utilization of Water Resources In construction phase of the Project, there will be water utilization to meet employees’ needs and construction purposes (concrete preparation etc.). There will be 70 employees in construction phase. Assuming that water consumption will be 150 L/cap-day, daily water consumption will be 10.5 m3 (70 people x 150 L/cap-day). Water consumption for construction activities is expected to be 10 m 3/day. Hence, total water consumption in the Project will be 20.5 m3/day in the construction phase. Similarly in the operational phase of the Project, there will be water consumption to meet employees’ needs. There will be 15 employees in operational phase of the Project and water consumption will be 150 L/cap-day. Therefore, daily water consumption will be 2.25 m3 (15 people x 150 L/cap-day). Water demand in the constructional and operational phase of the Project will be supplied from the water network of the city. 3.5.2 Utilization of Energy The required electric energy in the construction and operational phase of the Project will be supplied from the current electricity network 400 meter far away from the Project Site [1]. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 20/62 4 PROJECT SITE Designed Beypazarı WWTP is planned to be constructed in Hacıkara Mahallesi, Karapınar Mevkii. This area is located 4 km south of the Beypazarı county town. The map in the Figure 4-1 shows the Project site. 4.1 Geological Characteristic 4.1.1 General Geology In Beypazari, metamorphic rocks forming the Middle Sakarya Massif have been intersected by shallow batholite mass in low temperature and in different forms varying from granite and diorite. The batholite mass, also called as the Beypazari granite, is outcropped in the south of Kirmir Creek. Although it is covered with Eocene and Miocene- aged formations, it is possibly connected to the granite outcropped in Sivrihisar. Batholite mass has a homogenous structure. Beypazari granite is in contact with side rocks composed of phyllite, schist and marble. Hornfels with thickness varying between 3 and 10 m, along the contact zone are observed. In the side zones of the batholite mass, enclaves, which have intruded into this mass, are observed. Iron formations with silis are observed where this mass intercepts metamorphics with high iron content. During settling of granite, joint sets and cracks have developed while the mass was cooling down. In later phases, aplite and pegmatite dykes with thickness varying between 10 cm and 6 m and length varying with 10 m and 350 m in NE-SW and NW-SE directions have formed. Derivatives of batholite mass composed of granite and granodiorite often contains monzodiorite and diorite enclaves, which have formed earlier due to magmatic decomposition. The granite is mostly composed of quartz, plagioclase, orthoclase, and it includes amphibole, biolite, chlorite, zircon, sfen, apatite and opaque minerals in little amounts. In diorite, density of felsic minerals decreases whereas that of mafic minerals increases. Plagioclase and orthoclase are often observed to have converted into sericite while they are observed in chlorite form in biotites. Holocrystalline hypidiomorphic rocks are observed to be dominant within the mass while myrmekitic and allotriomorphic texture is also observed [2]. 4.1.2 Seismicity and Tectonic Characteristics Project Site lies within the 3rd Degree Earthquake Zone according to the Earthquake Map prepared by the Directorate of Disaster and Emergency Management of the Prime Ministry, and hence, possibility of occurrence of an earthquake with high magnitude is low. The earthquake map of Ankara where the project site is located is given in Figure 4-3 whereas Active Fault Map of Turkey is given in Figure 4-4. As can be seen from the Earthquake Map of Ankara, there are no important fault lines in the area. The longest fault line in the region is Nallihan-Nuhhoca fault located to the north of the district [3].

Figure 4-4 Active Fault Map Showing the Project Site Design of any structures to be constructed within the context of the Project will be made in compliance with the provisions of the “Regulation on Structures to be Constructed in Disaster Areas”. 4.2 Climatic Characteristics Beypazari District is located in Upper Sakarya Basin, lying in the northwest of Middle Anatolia. Middle Anatolian Steppe Climate is observed in the district. About half of the annual precipitation falls in the winter while summers are mostly dry. Precipitation regime is similar to Mediterranean Climate but annual amount of precipitation is about half of the amount of precipitation observed in Mediterranean Climate [URL-1]. Beypazari Meteorological Station is the nearest meteorological station at which observations reflect the meteorological characteristics of the project site the best. Therefore, climatic characteristics of the Project Site and its vicinity are given by referring to this long-term data recorded between 1975 and 2005. According to the meteorological data, average annual maximum temperature recorded was +43.0 °C (30 July 2000) and the minimum temperature recorded was -17.7 °C (22 February 1985). Average annual temperature of Beypazari is +13.0 °C. January is the coldest month with an average temperature of -1.1 °C and July is the hottest month with +24.8 °C. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 24/62 In this region, the average annual precipitation was recorded as 396.2 mm and the most precipitation is observed in winter. Average number of days with snow is 17.4. According to the long-term meteorology data, average annual wind speed is 1.6 m/s. West-southwest is the dominant wind direction. 4.3 Water Resources 4.3.1 Surface Water Resources The most important surface water source in Beypazari is Inozu Creek. It rises near Usakgol Village and joins Kirmir Creek in the south. Currently, wastewater generated in Beypazari District is being discharged to Inozu Creek [URL-1]. Catagan Creek flows in the east of the district while Zaviye and Findicak creeks flow in the west, and Alan Creek flow in the north near Basoren Village. Flow regimes of these creeks are not regular. These rivers deposit the alluvium, which they carry from the upstream, to their beds. Pebble, sandstone, claystone, slope debris and bank gravel is observed along Inozu Creek. Kirmir Creek rises in Işık Mountains, and it has many tributaries. All the rivers except for Karakuyu Creek are medium salty and low in sodium. Karakuyu Creek is very salty with a sulfate concentration around 90% [URL-1]. 4.3.2 Groundwater Resources The most important groundwater resource in this region is Karakoca Mineral Water Resource. It discharges from rhyolites and its flow rate is 2 L/h originating from magmatic rocks, this water is colorless, odorless, clear, free of sediment, containing gas, magnesium and sulfate [URL-1]. Groundwater level is not very deep. It is used for irrigation of nearby agricultural lands. Groundwater reserve is 1.2x106 m3/year in the region. However, in alluvial areas, ground water can be drawn easily [URL-1]. In the general case, groundwater replenishment decreases when flow rate of water stream is high, especially high precipitation case such as snow formation. On the other hand, it increases when flow rate in the stream decreases, and snow melts. There are a number of 11 hot springs discharged from the fault zone located 20 km to the southeast of the district. These sources are located in granites outcropped in the district. Temperatures of these sources vary between 42.0 and 51.5 °C while their flow rates vary between 0.1 and 2.6 L/sec [URL-1]. A thermal hotel that will utilize these sources is planned to be established in the district. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 25/62 4.4 Socio-Economic Characteristics 4.4.1 Population Size and Growth Rate Address-Based Population Recording System (in Turkish: “Adrese Dayalı Nüfus Kayıt Sistemi”, ADNKS) has been implemented by Turkish Statistical Institute (TURKSTAT) since 2007. Population of the district center Beypazari is 35,080 according to 2009 figures of ADNKS. Population size and growth rate are among the main parameters used in the design of the WWTP. Therefore, population projection covering the Project lifetime has been carried out. Detailed information about population projection is given in Section 3.4.4. Comparing the results of population projections carried out using different methods, Bo P’s population projection method has been decided to be used. Using this method, population projection has been made by setting GC to 3.00 for the period between 2000 and 2021 and to 2.50 for the years after 2021. As a result of this projection, population of Beypazari has been determined to be 64,100 and 105,000 for the two stages, respectively. 4.4.2 Education According to information obtained from the official website of the Directorate of Education in Beypazari, there are 18 primary schools, eight elementary schools, a vocational school and a public education center in Beypazari [URL-2]. As mentioned in Section 3.4.1, there are two vocational schools in Beypazari in which there are a total of 500 students. 4.4.3 Economical Characteristic Agriculture, trade, animal husbandry, industry and handicrafts are important activities for Beypazarı economy. Major agricultural products grown in Beypazari are carrot, lettuce, tomato, onion and wheat. Carrot production in Beypazari accounts for 44% of Turkey’s total production whereas lettuce production accounts for 20% of the total production in Turkey. A part of 67% of the people in Beypazari carries out agricultural activities [URL-3]. Historical texture as well as various local foods and souvenirs produced in Beypazari attract many tourists. This makes livelihood in the economic life in Beypazarı. As also explained in Section 3.4.1, there are many industrial establishments in Beypazari including a milk and dairy products plant and a slaughterhouse. In addition to these, there are Industrial District of Carpenters and Small Industrial District. In the Small Industrial District, mostly car maintenance and machine repair works are carried out. Besides these, an industrial district is planned at a location 6 km away from the district center. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 26/62 4.5 Ecological Characteristic In this section, information about species of flora and fauna present or likely to be present in the Project Site and its vicinity is presented. 4.5.1 Flora The proposed Project Site lies in a transition spot between Irano-Turanian and Europe- Siberia Phytogeographic regions. Project Area, consisting of wastewater treatment plant, collector lines, and pump stations, is under the effect of anthropogenic sources. In other words, agricultural lands are highly present in the vicinity of Project Area. Therefore, development of natural vegetation has mostly been suppressed. Land available for survival of natural flora has decreased. Field work carried out in June 2010 to determine flora and fauna structure in the Project Site and the impact area have focused on not only the species observed in the Project Site but also the species that are likely to be observed in the Project Site due to their biotope characteristics. During the study, endemic species and habitats protected in the context of international agreements including Bern, Ramsar, Biodiversity and CITES have been taken into consideration. Black pine and oak are observed in the region. As a result of flora surveys, the vegetation types observed in the Project Site and its vicinity are wayside vegetation and steppe. Wayside Vegetation The flora species observed on the wayside are widespread, and are not endangered. These types of species are given below: Grass inflorescence (Bromus cappadocicus), Bromus tectorum, Galium verum, Poa (Poa pratense), Dandelion (Cichorium intybus), Onosis (Ononis spinoza), Milk Thistle (Eryngium campestre), Artedia squamata, Torilis arvensis, Trefoil (Medicago radiata), Couch Grass (Dactylis glomerata), Arnica (Anthemis tinctoria), Dock (Rumex crispus), Cinquefoil (Potentilla reptans), Gum-Plant (Euphorbia macroclada), Greek Clover (Melilotus officinalis), Grasspea (Lathyrus aphaca var. biflorus), Leontodon hispidus var. hispidus, Sisymbrium altissimum. Steppe This type of vegetation observed in the Project Site and its vicinity is widespread in Middle Anatolia Plateu in areas with elevation below 1200 m. This vegetation usually consists of herbaceous species and partially low hedge species. It was observed that anthropogenic factors affected this vegetation. The flora species observed in steppe vegetation are widespread, not endangered with an average height of 45 cm and 70% coverage. Mostly encountered species are given as follows: Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 27/62 Poa nemoralis, Ferulago pauci radiata, Arnica (Anthemis tinctoria), Anthemis cretica, Stipa arabica, Alyssum murale, Gum-plant (Euphorbia macroclada), Leontodon hispidus var. hispidus, Milk Thistle (Eryngium campestre), Cinque foil (Potentilla recta), White Clover (Trifolium arvense), Caucalis platycarpos, Scabiosa argentea, Trefoil (Onobrychis armena), Cornflower (Centaurea virgata). 4.5.2 Fauna The fauna elements in the Project Site were determined according to field surveys, literature data and the information obtained from local people. The major types of fauna are the taxa which are widespread in cultivated areas and near settlement areas. Amphibians Marsh frog (Rana ridibunda) and Bufo viridis living in aquatic and semi-aquatic environments can reproduce in suitable habitats in the Project Site and its vicinity. These species are protected under Bern Convention. Mentioned species are under the LC “Least Concern” statue in IUCN Redlist. Possible impact of the construction on amphibians and reptiles is the obstruction of their migration path. Mitigation measures during the construction and operation period of the Project are provided in Section 5.7 Reptiles Of the eight reptile species that are present or likely to be found in the Project Site and its vicinity are turtle, lizard (three different species) and snake (four different species). And their threat status is provided in the table below. Birds Project Site and its vicinity provide suitable habitats for singing birds (Passeriformes). Bird species in the Project Site and its vicinity are under the LC “Least Concern” statue in IUCN Redlist and are not endangered. Mammals Diversity and population density of mammal species are low in the Project Site and its vicinity since these areas have been affected by anthropogenic factors. Species that might be observed in the Project Site and its vicinity are Porcupine (Erinaceus concolor), Spermophilus xanthoprymnus, Weasel (Mustela nivalis), Rabbit (Lepus europaeus), Fox (Vulpes vulpes), Gray wolf (Canis lupus). Species except Spermophilus xanthoprymnus (Asia Minor Ground Squirrel) are under the LC “Least Concern” statue in IUCN Redlist and are not endangered. Flora and Fauna Species protected under National Legislation and International Agreements Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 28/62 Middle Anatolia is one of the sensitive areas in Turkey in terms of endemic plants. However, no endemic species were observed during field surveys since there are few natural habitats, and anthropogenic vegetation is dominant in the Project Site and its vicinity. Besides, there are no plant species protected in accordance with CITES and Bern Convention. All amphibians and reptiles living in Project Site are protected in accordance with the Bern Convention. All the bird species excluding Garrullus glandarius (Jay), Pica pica (Magpie), Corvus monedula (Jackdaw), Corvus frugilegus (Rook), Corvus corone (Hooded Crow), Corvus corax (Raven) and Passer domesticus (House Sparrow) are protected under Bern Convention. Table 4-1 presents the list of species of amphibians, reptiles, birds and mammals that are likely to be observed in Project Site and in its vicinity, and protected in accordance with the Bern Convention. Protection status of species according to International Union for Conservation of Nature (IUCN) is also given in Table 4-1.

These decisions are made by public institutions authorized for protection of nature, and revised annually. In addition, all species listed above will have abandoned the Project Site when the construction activities start and come back when the period is ended. Since the construction impacts are temporary, the impacts will be for a limited time. 4.6 Protected Areas An investigation has been made to see whether there are any protected areas (e.g. national parks, wetlands of international importance and wild life protection areas) in the vicinity of the Project Site by using the Geographical Information System (GIS) that can be accessed from the official website of the Ministry of Forestry and Water Affairs (http://korunanalanlar.ormansu.gov.tr/). A snapshot of the GIS screen showing the Project Site is given below. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 31/62 Project Site Figure 4-5 Project Site and Nearby Protected Areas The closest wetland is Sariyar Dam Reservoir. It is not within lists of “Protected Areas” of Ministry of Forestry and Water Affairs and Ramsar Wetlands. . The bird fly distance between the Project Site and Sariyar Dam Reservoir and is around 7 km. With the issue of Sariyar Dam Reservoir, articles of Regulation on the Protection of Wetlands will be complied. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 32/62 4.7 Cultural and Archaeological Assets Beypazari District of Ankara Province has an important place in the history. It dates back to Hittite and Phrygia. It is understood from ancient materials and maps that Beypazari is formerly called as Lagani and later Anastasiopolis, and it is a center of Episcopacy [URL-4]. Archaeological assets dating back to early historic periods are observed through literature research. Some of these are Rock Cemeteries and Rock Churchs (First Degree Archaeological Site), Byzantine Ruins and Cemetery (First Degree Archaeological Site) are First Degree Natural Sites [4]. The Beypazari Houses located in the district center are important cultural and natural assets dating back to recent periods. Located on steep slopes, the Beypazari Houses have high visual value with characteristic tissue and natural landscape features. These houses, with an age around 100 years, also bear characteristics of Ottoman and traditional Turkish houses. These are generally two or three storey buildings having a penthouse with oriel window [4]. Figure 4-6 shows an example of a Beypazari House. Reference: http://www.tmresimler.com/img3088.htm Figure 4-6 Beypazari Houses As a result of examination of the Project Site and its vicinity, no archaeological assets, items or evidence have been observed. In case of a coincidental finding in the Project Site, construction works will be stopped immediately, and the relevant museum directorate will be notified in compliance with the pertinent legislation5. In this case, construction activities will continue according to provisions of the museum directorate. If during the construction period of the Project, any archeological items will be founded, the works of 5 Article 4 of the Law on Protection of Cultural and Natural Assets (OG dated July 23, 1983 and numbered 2863): Obligation for Notification. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 33/62 the Projects will be formed according to the related regulation which is Protection of Cultural and Natural Entities (Law No: 2861 OG publish date: 23.07.1983). 5 ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES In this section of the EIA Report, possible environmental impacts that will result from activities to be carried out during construction and operational phase of the Project are assessed. Main treatment plant, collector lines and pump stations will be built and operated in project, therefore this section deals with the impacts and mitigation measures of all of these activities. During the construction phase, main sources of these impacts are solid and liquid wastes as well as noise and dust emissions. Magnitude of these impacts on such receiving elements of the environment such as air, water and soil are explained under respective subtitles, along with the mitigation measures that are required to be taken in order to minimize these impacts. 5.1 Solid Wastes 5.1.1 Domestic Solid Wastes Solid waste that may be generated during construction and operational phases comprises the domestic solid waste from workers, packaging waste and excavation material from construction works. The number of employees to be working in the construction and operational phases of the Main WWTP is 70 and 15, respectively. Solid waste generation is assumed to be 1.34 kg/cap-day, and the amount of domestic solid waste generated in the construction and operational phases of the Main WWTP is calculated approximately 94 kg/day and 20 kg/day, respectively. In construction phase of collector lines, 5 employee will be working. Solid waste generation can be taken 0.67 kg/cap-day like aforementioned part of the project, main treatment plant, so amount of solid waste generated in the construction phase of collector lines will be 6.7 kg/cap-day. Collector lines will be full automated, so there is no need for employee in the operational phase of the collector lines. There will be built pump stations in scope of the project. 10 employee will be working in constructional phase of pump stations. Amount of solid waste that will be generated is 13.4 kg/cap-day. There is no need for employee in operational phase. Domestic solid waste generated in the construction and operational phases of the Project will be transported to the Municipality’s solid waste dump site with the approval of Municipality by Municipality’s trucks. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 34/62 Waste packages of large piece of equipment as well as packaging waste (e.g. boxes and bags containing workers’ foods) that may be generated by the workers will be transported to packaging waste recovery facilities, licensed by the MoEU in compliance with the Packaging Waste Control Regulation (OG dated 24.06.2007 and numbered 26562). 5.1.2 Wastes Generated at the WWTP in Operational Phase On the operational phase of the Project, solid waste will be generated by coarse and fine screens and aerated grit and grease chamber. Solid waste generated in these units will be transported and disposed of together with domestic solid waste. Collected grease will be in the form of foam which is handled as solid waste. Analysis will be done if the wasted foam will be handled as hazardous or non-hazardous solid waste. Besides such wastes, there will be also treatment sludge. Considering the characteristics and contribution of the industrial wastewater flow, the treatment sludge is expected to be non-hazardous. Ankara Metropolitan Municipality’s Tatlar Wastewater Treatment Plant Sincan will be used as the final sludge handling location. Produced sludge will be transported with suitable containment of trucks by Ankara Water and Sewerage Administration (ASKI). Since the daily produced sludge amount is calculated as 9.88 m3, one (1) truck will be used for the transportation of sludge. At Tatlar Wastewater Treatment Plant, drying process will be used to decrease the water content of sludge. The landfill for disposal of treatment sludge will be handled in compliance with the pertinent provisions of the Landfilling Regulation (OG dated 26.03.2010 and numbered 27533) regarding sealing layer, leachate collection system, landfill gas management and water content of sludge etc. According to this Regulation water content of sludge shall be less than 50%. Table 5-1, provided below, shows the sludge water content after dewatering and drying processes. Table 5-1. Technical Specifications of Sludge Handling Units Unit’s Name Parameter Unit Value Dewatering (Decanter) Sludge Water Content (Exit) % 18-22 5.1.3 Excavation Material In the construction phase of the Project, excavation waste will be generated during site preparation and excavation of foundations of structures. Excavation works will be done for main treatment plant, collector lines and pump stations. Information about mitigation measures that should be taken and explained below is for all these three compartments. Vegetal top soil will be stripped before excavation works. Vegetal soil will be stored in an appropriate part of the site with slope less than 5%, to be used in landscaping works. Maximum height of piles will be 1.5 m. Top of the piles will be grassed. Vegetal soil will be stored separately from other excavation earth, and it will be used in landscaping works. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 35/62 Other excavation material will be disposed of in areas designated by the Municipality in compliance with the Regulation on Control of Excavation Earth and Construction and Demolition Waste (OG dated 18.03.2004 and dated 25406). 5.1.4 Special Types of Wastes In this section, provisions about special types of solid waste, for which specific waste management principals are stipulated in respective regulations. Waste Batteries and Accumulators Waste batteries and accumulators will be generated after used batteries and accumulators of communication devices, electronic equipment and accumulators of vehicles and construction machines are changed. These waste batteries and accumulators will be collected and given to the institutions authorized for recycle and disposal of these wastes in compliance with the Regulation on Control of Waste Batteries and Accumulators (OG 31.08.2004 and dated 25569). In this regard, the Association of Producers and Importers of Mobile Batteries (TAP) is the only authorized institution to collect waste batteries. Sufficient number of special collection boxes for waste batteries will be obtained from TAP, and located in appropriate locations in the facility. When boxes are filled, batteries will be sent to TAP free of charge. Medical Wastes According to Article 91 of the Occupational Health and Safety Bylaw relating to measures that shall be taken against accidents in workplaces, there shall be doctor and infirmary in workplaces with 50 or more workers. Since the number of workers working in the construction phase of WWTP will be 70, an infirmary will be established in the Project Site. Considering the size of the Project and characteristics of the works carried out during construction, it is expected that little amount of medical waste will be generated in the infirmary. This medical waste will be transported to the temporary storage site of a medical institute, and disposed in accordance with the Regulation on Control of Medical Waste (OG dated 22.07.2005 and numbered 25883). Since the number of workers to be employed during operation phase is less than 50, it is not obligatory to establish infirmary and hiring a doctor. In case of accidents and injuries during Project activities, health institutions in Beypazari district center will be used. Hence, no medical waste will be generated in the Project Site. Worn-Out Tyres In case worn-out tyres of vehicles and construction machines are changed in the Project Site, these tyres will be given to collectors licensed by the MoEU in compliance with the Regulation on Control of Worn-out Tyres (OG dated 25.11.2006 and numbered 26357). Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 36/62 5.2 Liquid Wastes According to Section 3.4.1, water demand of personnel in construction and operational phases of the Project is taken as 135 L/cap-day. Assuming also that 80 percentage of the water consumed will be converted into wastewater, the amount of wastewater generated is calculated as 108 L/cap-day. Therefore, the amount of wastewater to be generated in the construction and operation phases of the main WWTP is calculated as approximately 7.5 m3/day ve 1.6 m3/day, respectively. Amount of wastewater to be generated in construction phase of collector lines and pump stations will be 0.54 m3/day and 1.08 m3/day respectively. Domestic wastewater generated during the construction phase of the Project will be treated in package treatment plant, and then discharged to the receiving water body, Inozu Creek. Treated wastewater in construction phase will be discharged to Inozu Creek satisfying also the standards given in Table 21.1 in the Water Pollution Control Regulation (OG dated 31.12.2004 and numbered 25687) for domestic wastewater. Wastewater generated during the operational phase of the WWTP will be treated in the WWTP satisfying the pertinent criteria given in the Urban Wastewater Treatment Regulation (see Section 3.4.5), and then discharged to Inozu Creek. According to the Notification on Sampling and Analysis Methods of the Water Pollution Control Regulation (OG dated 10.10.2009 and numbered 27372), samples will be taken from the discharged wastewater once every 15 days during operation of the 1st Stage, and analyzed by a laboratory accredited by Turkish Accreditation Agency (TURKAK), and authorized by the MoEU. In the 2nd Stage, sampling and analysis frequency will be twice a week. In addition to this internal monitoring requirement, water samples will be taken by the Ankara PDoEU once every two months during the 1st Stage and monthly during the 2nd Stage according to the same notification. An Environmental Permit for wastewater discharge shall be obtained for the package treatment plant to be used in the construction phase and for the WWTP in the operational phase of the Project, in compliance with the Regulation on Permits and Licenses to be Obtained According to the Environmental Law (OG dated 29.04.2009 and numbered 27214). According to this Regulation, an Environmental Officer (“Çevre Görevlisi”) with a license obtained in compliance with the Regulation on Environmental Officers and Consultancy Firms (REOCF, OG dated 12.11.2010 and numbered 27757) shall be employed during construction and operational phases. The Environmental Officer shall inspect the treatment plants in order to ensure that activities related to the treatment plants are carried out in compliance with the legislation put in force on the basis of the Environmental Law. Alternatively, the CONTRACTOR or the Municipality can make a contract with a Consultancy Firm having a license according to the REOCF. In this case, an Environmental Officer will be assigned by the Consultancy Firm to the treatment plants. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 37/62 5.3 Hazardous Wastes Main types of hazardous waste to be generated in the construction and operational phases of the Project are oil and air filters, which are changed during maintenance, of construction and operation machinery (e.g. bulldozer, excavator etc.), waste fabrics used in maintenance and empty paint and lubricant boxes. Besides these, there may also be hazardous waste resulting from fluorescent lamps and wasted printer cartridges. Hazardous waste to be generated within the Project Site during construction and operation activities will be collected in temporary hazardous waste storage area, which is surrounded by wire fences, bottom-sealed, and protected from precipitation, in compliance with the Hazardous Waste Control Regulation (HWCR) (OG dated 14.03.2005 and numbered 25755). In the context of Waste Management Plan (see Section 7.2.1), workers will put hazardous waste material in the storage area. Hazardous waste shall not be stored for more than 180 days. Stored hazardous waste shall be given to firms licensed by MoEU for collection of hazardous waste. Hazardous waste collected from the Project Site shall be transferred to licensed intermediate storage areas, and then to hazardous waste landfills or incineration plants for final disposal. 5.3.1 Sludge Daily sludge production from dewatering unit is calculated as 9.88 m3. Although the treatment sludge is expected to be non-hazardous, it will be analyzed according to Annex- 11/A to HWCR, in which criteria for waste to be landfilled in solid waste landfills are given. After the dewatering process, sludge will be transported to Tatlar Wastewater Treatment Plant owned by Ankara Metropolitan Municipality located in Sincan. Possible impacts of the inappropriate handling of the sludge are; odor problem, potential health risk because of pathogens, toxicity arising from high load of heavy metals. Mitigation measures to prevent such risks are; application of a site-specific odor control plan, chemical dosing to reduce pathogen level, and continuous analysis of sludge for the heavy metals content to classify as “non-hazardous”. 5.4 Waste Lubricant Construction machines, trucks and cars are the sources of waste lubricant in construction and operational phases. Repair and maintenance of all the vehicles will be carried out in authorized services outside the Project Site. Lubricant of construction machinery will be changed at the Project Site by the personnel of authorized service. Waste lubricant resulting from maintenance works shall be given to firms licensed by the MoEU for collection of waste lubricant in compliance with the Waste Lubricant Control Regulation (OG dated 30.07.2008 and dated 26952).

Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 38/62 5.5 Air Emissions 5.5.1 Gas Emissions It is anticipated that a boiler with thermal power less than 1 MW will be used for heating of administrative building. The boiler will be operated, and its emissions will be monitored through periodical measurements in compliance with the Regulation on Control of Air Pollution due to Heating (OG dated 13.01.2005 and numbered 25699). Besides heating, there will be air emissions due to exhaust gas of vehicles and construction and operation machinery. Hourly fuel consumption rate of vehicles and machinery is anticipated as 50 L, and mass flow rate of pollutants are calculated accordingly. In these calculations, density of diesel is assumed to be 0.8654 kg/L6. Emission factors and emission amounts for pollutants emitted from diesel vehicles are given in Table 5-2 along with the related limit values. Table 5-2 Emission Factors and Amounts of Pollutants Emitted from Diesel Vehicles and Related Limit Values Emission Factor* Emission Amount Limit Values** Pollutant (kg/ton) (kg/hour) (kg/hour) Carbon monoxide 9,7 0,420 50,000 Nitrogen oxides 36 1,558 4,000 Sulfur oxides 6,5 0,281 6,000 Dust 18 0,779 1,500 * Reference: Muezzinoglu, A.,”Principles of Air Pollution and Control” (original Turkish title: ‘Hava Kirliliginin ve Kontrolunun Esaslari’, Dokuz Eylul Universitesi Yayinlari, 1987. ** Reference: Table 2-1 in Annex-2 to the Regulation on Control of Industrial Air Pollution (RCIAP) (OG dated 03.07.2009 and numbered 27277) As it is seen from Table 5-2, air emissions to result from construction machinery are below the limit values given in Table 2-1 of Annex-2 to RCIAP. Therefore, emissions from vehicles are not expected to cause an adverse impact on the ambient air quality. Exhaust emissions of construction machinery and vehicles will be controlled through regular maintenance. In this respect, provisions of the Circular on Exhaust Gases of Motor Vehicles (OG dated 30.12.2004 and numbered 2004/13) shall be complied with. 5.5.2 Dust Emissions The construction activities that may generate dust are listed below.  Transport on unpaved roads,  Site preparation and excavation works,  Transport, utilization and storage of construction materials and  Transport of excavated material. Dust emissions from construction activities are calculated assuming dust emission factor of 9.9 gr/m2/day for semi-dry areas. This factor has been calculated based on a formula 6 TMMOB Kimya Muhendisleri Odasi Yayinlari, 1991 Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 39/62 given by the United States Environmental Protection Agency (USEPA) considering various construction sites. The formula below has been used to calculate dust emission rates in construction sites:   g  day   Area (m 2 )  Dust Emission = 9,9 2 x  x  m  8hour   30day  excavation duration x   1month   Considering the worst-case scenario, it is assumed that all the dust emissions will be generated at the same point. Dust emissions that may result during construction works are calculated and given below. It is anticipated that excavation and construction works of WWTP will be carried out in an area of 45,988 m2. Duration of construction is predicted as 12 months. However, it is considered that activities likely to cause intense dust emission will be completed in the first 3 months. Taking this into consideration, dust emission calculations are carried out below.   g  day   45,988m 2 )  Dust Emission = 9.9 2 x  x  = 632.32 g/hour = 0.63 kg/hour m  8hour   30day  3 month x    1month  Excavation and construction works of collector line will be carried out in an area of 53,400 m2. Construction of collector pipe will start and end with construction of WWTP simultaneously. Duration of construction is predicted as 12 months and activities likely to cause intense dust emission will be completed in 12 months. It is because; almost all activity will be excavation process in construction of collector line.   g  day   53,400m 2 )  Dust Emission = 9.9 2 x x  = 183.5 g/hour = 0.184 kg/hour m  8hour   30day  12 month x    1month  Excavation and construction works of pump 3 pump stations will be carried out in an area of 450 m2 approximately.(TM-1 200 m2, TM-2 200 m2, TM-3 50 m2) Duration of construction and duration of activities likely to cause intense dust emission will be 3 months and 1 week respectively.   g  day   400 m 2 )  Dust Emission = 9.9 2 x  x  = 65.99 g/hour =0.067 kg/hour m  8hour  1 / 4 month x 30day    1month   Dust emission resulting from construction activities is calculated as 0.88 kg/hour in first 1 Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 40/62 week and 0.814 kg/hour till the end of 3 months. This is below the limit value of 1.0 kg/hour, beyond which air quality modeling study shall be necessary according to Annex-2 to RCIAP. Therefore, an air quality modeling study was not carried out to determine suspended and settleable dust concentrations. Moreover, these are total values of three main compartments of the project and they are not in same construction area. Hence, it is expected that the closest sensitive receptors, which are the houses located approximately 500 m to the north of the WWTP, and houses around collector line and pump stations will not be adversely affected by the dust emissions resulting from construction works. Dust emissions due to excavation works may result in following impacts to the surrounding biological and physical environment.  Impacts on flora by inhibiting photosynthesis,  Disturbance on the terrestrial fauna,  Respiratory illnesses,  Increasing turbidity in surface water. Impacts due to dust emission will be minimized through implementation of the following measures: In order to prevent or minimize dust emission at soil piles, it shall be watered in dry and windy weather for dampening, 30 km/hour speed limit shall be set on non-paved road, Roads in the Project site shall be watered to prevent dust formation. Covering of trucks with canvas. 5.5.3 Odor In general, no significant odor formation is expected at a WWTP since aeration activity prevents formation of odorous compounds. Only in certain sections of the WWTP, there will be odor due to hydrogen sulfide formation caused by lack of oxygen. However, these sections are generally, small compartments such as distribution structures. Hence, odor formed in a domestic wastewater treatment plant does not cause significant nuisance in the vicinity. Besides, since dominant wind direction is west-southwest, and Beypazari district center is located about 4 km (as the bird flies) in the north, people living in the district center are not expected to be adversely affected by the odor formed in the WWTP. 5.6 Noise The list of construction machinery that will be used in the construction phase of the WWTP and relevant sound power levels are given in Table 5-3. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 41/62 Table 5-3 Construction Machines and Relevant Sound Power Levels Machines Count Sound Power Level (Lw), dBA Truck 5 85 Wheel Loader 2 110 Compactor 1 110 Excavator 1 105 Bulldozer 1 120 Noise level calculations have been carried out for the worst-case scenario in which all machines are working simultaneously. Therefore, actual noise level will be much lower than the calculated value. It is not possible to provide information about exact locations of the construction machines. Equivalent noise level caused by all noise sources is calculated using formula (1) given below (METU-CEC, 2007). In this formula it is assumed that all the noise sources are at the same level. n Li Leq  10  log 10 10 ………………………………… (1) i 1 In this formula; n = Number of noise sources, Li = Sound power level of each source (dBA), Leq = Total equivalent noise level.  5x10 10  2 x10 10  1x10 10  1x10 10  1x10 10  Leq  10  log 85 110 110 105 120  = 121.3 dBA   For construction phase of WWTP noise level at the source is calculated as 121.3 dBA Construction machines that will be used in collector pipe are 2 excavators, 2 compactors and 4 trucks.

Construction machines that will be used in pump stations are 1 excavator, 1 compactor and 2 trucks. According to table 5-3 and formula (1) given above;  2 x10 10  1x10 10  1x10 10   Leq  10  log 85 110 105  = 111.2 dBA   Sound power level (Lp) at a specific distance can be calculated by using the formula (2) below.

However considering the worst case scenario, it is assumed that atmospheric absorption is negligible and all machines are working at the same point. Noise level with respect to distance was calculated by using the formula given above, and calculation results are given in Table 5-4 and Figure 5-1. Table 5-4 Distribution of Noise with respect to Distance LW (dB) Collector LW (dB) Pump r (m) LW (dB) WWTP Line Stations 0 121,30 114,2 111,2 10 93,32 86,22 83,22 50 79,34 72,24 69,24 100 73,32 66,22 63,22 200 67,30 60,2 57,2 300 63,78 56,68 53,68 400 61,28 54,18 51,18 500 59,34 52,24 49,24 600 57,76 50,66 47,66 700 56,42 49,32 46,32 800 55,26 48,16 45,16 900 54,23 47,13 44,13 1000 53,32 46,22 43,22 1500 49,80 42,7 39,7 2000 47,30 40,2 37,2 2500 45,36 38,26 35,26 3000 43,78 36,68 33,68 3500 42,44 35,34 32,34 Note: Frequency interval of construction machines is between 500-4000 Hz. Therefore, sound power level at each point is very close to noise level. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 43/62 140 120 Sound Power Level (dBA) 100 80 60 40 20 0 0 500 1000 1500 2000 2500 Distance (m) Figure 5-1 Distribution of Noise with respect to Distance Noise limit values for construction sites are stipulated in Article 23 of the Regulation on Control of Assessment and Management of Environmental Noise (RAMEN) (OG dated 04.06.2010 and numbered 27601). These limit values are given in Table 5-5. Table 5-5 Noise Limit Values for Construction Sites (ÇGDYY Ek-VII, Table 5) Activity (Construction, Demolition and Repair) Ldaytime (dBA) Building 70 Road 75 Other Sources 70 According to the Article 23 of RAMEN, noise level due to construction activities shall be below the limit value of 70 dBA (Table 5 of RAMEN) at such sensitive points as school, hospital and house. The closest sensitive point to the construction site of WWTP is a small hut (see Figure 3-5). This hut is approximately 100 m away from the proposed WWTP area. Hence, the expected noise level at the hut is 73.32 dBA (see Table 5-4), which is slightly above the limit value given in Table 5-5. Since this hut is not a proper settlement unit; it is rather used occasionally (see Section 3.5.1). Therefore, a continuous and heavy nuisance is not expected at the hut. The next closest settlement is the house located about 500 m to the north of the WWTP. Expected noise level at this house is 59.34 dBA (see Table 5-3). Therefore, this house is not expected to be adversely affected from the noise resulting from construction activities. The closest sensitive point to the construction site of collector line is a mosque. It is approximately 20m away from collector line. So, the expected noise level at the mosque is 80.2 dBA, which is above the limit value given in Table 5-5. Since the construction of Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 44/62 collector line will be along the line, construction vehicles will not work in same place so long and employees can excavate and construct 100 m collector line in 1 day, a continuous and heavy nuisance is not expected at the mosque. The closest sensitive points to all three pump stations are residential areas and they are approximately 400m away from collector line. So, the expected noise levels at these residential areas are 51.18 dBA. Therefore, these residential areas are not expected to be adversely affected from the noise resulting from construction activities. Calculating the noise to be resulting from construction machinery and equipment, it is assumed that all the machines and equipment will be working simultaneously at the same spot, and atmospheric absorption is neglected. It is expected that the noise level in the real case will be much lower than this calculated levels In order to minimize the noise during construction activities, maintenance of the machinery and equipment will be regularly made. Considering the characteristics of the construction machines and equipment to be used in the Project Site, noise that will result from construction activities will not increase the background noise level near the site considerably. There will not be any significant impact during operational phase of the Project at the nearest sensitive receptor. 5.7 Impacts on Flora and Fauna Since the Project Site is an agricultural area, there is no natural flora structure in the site. During the operation period of the Project, anthropogenic factors have been expected to have impact on fauna and flora, therefore on the biological diversity. For this reason; people who are temporarily or permanently stay within the Project Area will be ensured to keep the negative impacts on the flora and fauna at the minimum level. The gathering plant species, the damage on wild animal species, hunting or killing those animals will be definitely prevented. But, there is no observation of such an issue on the Project Site. However, a small tunnel, passing below the road, can be built to be on the safe side. The construction area might be disturbing for the fauna as well as the adjoining vegetation. Fencing around the Project Site might help to prevent the inconvenience. Some species may already have their nests within the construction area. Adequate time may be given to the animals in order to move out from the Project Site or the nests might be moved to a similar habitat out of the Project Site. It is highly recommended not to start the construction period during the reproduction season of the threatened/vulnerable species. Trees within the construction site might be important for some species. If this is the case those trees might be transferred to a close are out of the Project Site. Turtle (Testuda graeca), yellow snake (Elaphe quatuorlineata), and Asia minor ground squirrel (Spermophilus xanthoprymnus) are categorized as near threatened. However, according to studies (Demirsoy, 2006), these species are widespread and are not Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 45/62 endangered in Turkey. Therefore, mentioned species will not be affected negatively from the Project’s construction and operational activities. During the construction of collector lines, top soil shall be separated and stored in a different area because, the biological cycle depends on existence of minerals, microorganisms, and seeds in the vegetative soil. In case of vegetative soil not being stored under appropriate conditions or mixing with sub-soil, biological cycle will not be completed. Therefore, growth of plants will be affected. Measure to be taken to prevent this situation is the laying soil layers separately. Collector lines will be under the agricultural lands so that natural vegetation will not be affected negatively by the collector lines construction. Moreover; Bern Agreement protection measures in regard to the fauna species listed in Bern Agreement Annex-2 and Annex-3 as well as 6th and 7th articles of the agreement will be followed in the operation stage of the project. 5.8 Public and Occupational Health and Safety In the construction phase, there may be some nuisance or safety risks on the local people. In order to eliminate or minimize such impacts drivers of the vehicles carrying materials to construction site should obey speed limit of 30 km/hour. There will be barriers and warning signs around the construction site in order to prevent entry of local people into the site. There will be also warning signs on the road side in order to warn drivers about trucks entering or leaving the site. Barriers will be immediately built in excavation areas to prevent people from falling down. Excavated areas should be covered for public health or surrounded by warning signs if coverage is not possible. Pipe ends will be closed to prevent entry of animals. In order to eliminate occupational health and safety risks in the construction site, barriers should be employed to prevent landslide in deep excavation areas. National legislation regarding occupational health and safety will be complied with. Besides, nationally and internationally accepted procedures should be followed (e.g. use of personal protective equipment). Occupational health and safety procedures will also be covered in the context of training (see Section 7.5). Similarly, provisions in the national legislation regarding occupational health and safety will be complied with during the operational phase. Besides, nationally and internationally accepted procedures should be followed (e.g. use of personal protective equipment) in the operational phase. An Emergency Response Plan regarding accidents that may occur during WWTP operation should be prepared and approved by the Municipality. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 46/62 6 EVALUATION OF ALTERNATIVES As mentioned before, final design studies have been conducted for the Project by the BoP. As a result of these studies, Final Design Report has been prepared for the WWTP. In the scope of final design studies, only one treatment system alternative has been considered. Therefore, our second technology alternative will be “no action”. Similarly, during design studies, no alternative sites have been considered. Detailed assessment of these alternatives is given below. 6.1 Alternatives for the Project Site The BoP has conducted surveys before and during the final design studies in cooperation with the Municipality. As a result of these studies, an area (see Appendix-A), which is the property of the Municipality, receiving most of the wastewater by gravity flow, has been selected. In this context, no other alternative sites have been considered for the WWTP. Taking social concerns into account, eliminating resettlement and economic displacement is favorable. Therefore, the proposed site is deemed appropriate for realizing a Category A project financed by the WB Group. 6.2 Technology Alternatives 6.2.1 No Action In the “no action” alternative, wastewater generated within Beypazari District would continue to be discharged into the receiving surface water medium without any treatment. In this case, the problems that are mentioned in Section 3.3 will be experienced. Such problems are the actual reasons behind development of the wastewater engineering, and have led a significant number of wastewater treatment practices in the entire world. In this respect, untreated discharge of wastewater will mainly cause extensive pollution in surface and groundwater. Surface and groundwater pollution will subsequently cause human health problems (e.g. blue baby disease). Surface water pollution will also trigger deterioration of aquatic ecology, and adversely affect biodiversity in the river environment. 6.2.2 Selected Alternative Considering the treatment technologies widely used in the world, suitable processes that may be used in urban WWTPs are listed below.  Attached growth systems  Trickling filter,  Suspended growth  Stabilization ponds,  Sequencing batch reactor,  Conventional activated sludge system, Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 47/62  Extended aeration activated sludge system. All the processes are capable of removing BOD and SS at the required level. However, since there is a risk of eutrophication in the receiving body where the treated wastewater will be discharged, treatment of nitrogen and phosphorus is also necessary in compliance with the Urban Wastewater Treatment Directive. In terms of phosphorus removal, each of these processes is not sufficient alone. Therefore, anaerobic tanks should also be included in these processes for phosphorus removal. As for the nitrogen removal, aeration duration should be longer. Since sludge handling also incurs high costs for the operator of the WWTP, extended aeration activated sludge process has been selected considering that it generates low amount of sludge. 6.2.3 Alternatives for Sludge Management Composting may be considered as another alternative for the sludge management technology; however, since this application is not feasible for the Project with respect to land limitation and soil quality protection issues and also cost point of view, sludge handling cited in the report is declared as final decision. Selected method for the sludge handling dewatering (use of decanter) of the sludge. However, with these methods, deserved solid content can’t be met. Therefore, drying process is selected for the final handling of the sludge. Drying process will be executed since the Sludge Drying Facility of Tatlar Wastewater Treatment Plant will become operational till the end of 2014. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 48/62 7 ENVIRONMENTAL MANAGEMENT PLAN 7.1 Purpose and Scope In this chapter, the mitigation measures that shall be taken in order to eliminate or minimize the environmental effects caused by activities carried out during the constructional and operational phases of the Project explained and a monitoring plan shall be used for monitor the environmental effects of the Project is presented. Main treatment plant, collector lines and pump stations will be built and operated in project, so mitigation measures and monitoring plan should be taken for these three compartments. The list of the mitigation measures and monitoring plan is prepared according to both WB standards and national environmental legislation. The objectives of the Environmental Management Plan (EMP) prepared for the Project are listed below:  To address the environmental consequences resulting from the activities performed during construction and operation periods of the Project,  To specify related mitigation measures considering both the national legislation and WB’s criteria,  To propose environmental monitoring program,  To set-up an institutional structure where environmental issues are followed up during construction and operational phases of the Project,  To inform local people, governmental and non-governmental organizations (NGO) about the Project. 7.2 Responsible Parties Municipality is the main beneficiary of the Project.

Emergency Response Plan regarding accidents that may occur during WWTP operation should be prepared and approved by the Municipality. 7.4 Monitoring Plan It is suggested that environmental monitoring studies should be conducted separately (with different scopes) because different activities during construction and operation period of the Project will result in different possible environmental impacts. Data acquired during monitoring studies will be compared with national legislation items which are mentioned in Chapter 2. 7.4.1 Construction Phase Monitoring every environmental parameter continuously is not practical and necessary. Environmental monitoring functions according to the characteristics of existing environmental conditions and identifies unacceptable changes during construction period. In this context, monitoring plan is designed to commit that “project activities have no permanent negative effect on environmental resources”. For construction period, air quality, waste management applications and noise levels will be monitored and the results will be compared to legal limit values. Contractor will prepare a report about monitoring studies according to the following program and offers it to the Municipality:  Daily environmental non-compliance report (if any),  Monthly environmental monitoring reports in which environmental performance of the Project is evaluated according to EMP requirements. 7.4.2 Operational Phase In the operational phase less environmental impact is expected than in the construction phase. Municipality will prepare and submit environmental monitoring reports to the BoP semi-annually. Monitoring plan related with the Project is given in Table 7-2.

Alternatively, the MUNCIPALITY can sign a contract with a private laboratory having the necessary qualifications to carry out analyzes. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 56/62 7.5 Institutional Strengthening In general, in this section of EMP’s, the recommendations related to the institutional strengthening are provided in order to ensure that environmental measures are applied for an environmentally sound and sustainable project development. In this context, in the construction phase of the Project, Municipality will hire an environmental consultant to follow up whether requirements of the EMP will be implemented. This environmental consultant should be a company or establishment authorized by the MoEU in compliance with the Regulation on Environmental Inspection (see Chapter 2). Environmental consultant will be basically responsible for coordination between the Municipality and the Contractor, which is responsible for environmental monitoring to be carried out in the construction phase. Alternatively, Municipality can have an Environmental Officer within its organization in order to carry out the same task. An environmental consultant or Environmental Officer of the Municipality will be employed for the same purpose in the operational phase as well. 7.5.1 Equipment Purchase Environmental measurements and analyzes will be carried out by a company authorized by the MoEU for carrying out environmental measurements and analyses according to the requirements of the Turkish environmental legislations and a laboratory accredited by Turkish Accreditation Agency (TURKAK). Therefore, Municipality does not need to purchase equipment for environmental monitoring. 7.5.2 Training Environmental consultant will assign an environmental engineer7 to inspect the proposed environmental monitoring works at the Project Site. Prior to the execution of the environmental monitoring works, environmental engineer will carry out a training campaign in order to increase the awareness of the construction staff about environment and occupational health and safety and to convey the requirements of the EMP. The scope of the training will include mainly the scope of the EMP, the relevant environmental legislation of Turkey, requirements of the WB and the following concepts should be included in the training program:  Understanding of the Project’s environmental requirements and their implementation at the site by the staff (i.e. what kind of environmental impacts are expected and what kind of mitigation measures are proposed; where and how to take these measures);  Occupational health and safety procedures to be followed at the site;  Understanding of the procedures to be followed in improper situations;  Reporting principals and understanding rules; 7 Environmental Engineer, is an authorized person as “Environmental Officer (in Turkish: Çevre Gorevlisi)” according to the Environmental Audit Regulation Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 57/62  The Project’s environmental dimension and informing the related official institutions about it;  Understanding how to treat the public and media visiting the site; and  Understanding how to act in case of unexpected environmental accidents. The Contractor is in charge of keeping the records related to the environmental training of the staff. Internal HSE monitoring should test the effectiveness and the adequacy of the training. 7.5.3 Consultancy Services The environmental engineer assigned by the Municipality will do provide environmental consultancy services to ensure the compliance with environmental rules and regulations as well as guidelines and to meet the requirements that may occur during audits by the WB or local authorities such as Ankara PDoEU. The environmental engineer will carry out monitoring work outlined in Section 7.4 and will hold meetings with construction contractor to obtain information about the progress in the works as well as environmental issues encountered. 7.5.4 Public Relationship Handling with Complaints During the construction phase of the Project, the Contractor will prepare a procedure to direct complaints to the Municipality. The Municipality is responsible to deliver the phone numbers, mail and e-mail addresses to interest groups (local people and NGO’s) for receiving and recording any complaints. Hence, a public relations mechanism will be constructed by the Municipality for the complaints from local people, NGO’s and governmental establishments of the district. In this regard, any complaints received will be recorded by a Complaints Desk to be formed within the Municipality. Complaints will be recorded by this unit, and directed to the Directorate of Water Network. After evaluating the complaints, the department will force the Contractor to take necessary corrective action. The complainant will be informed about the progress after necessary measures are taken and the subject environmental problem is resolved. All records of complaints and relative action taken will be recorded by the Complaints Desk. A public relation mechanism should be established by the Municipality in the operational phase of the Project like the one developed in the construction phase and the public relations process will be followed by this mechanism in order to evaluate complaints and suggestions from people. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 58/62 7.6 Institutional Arrangements This section gives information about how and by whom the environmental monitoring data will be used. 7.6.1 Construction Phase The Municipality is the responsible party to minimize or eliminate possible environmental impacts of the Project. Therefore, to guarantee the environmental performance of the Project, the Contractor will be aware of his/her responsibilities in the construction period. In this way, the Contractor will be aware of the environmental responsibilities and the requirements of Project. Contractor will perform the following activities for a balanced environmental performance:  Assigning his/her own HSE personnel to implement the EMP,  Working in coordination with Environmental Engineer to ensure that the personnel working in the construction period are trained to raise the consciousness on environmental issues and EMP requirements,  Minimization of the emissions and noise originating from the construction equipment, protection of water resources, compliance with the requirements of EMP. The Contractor, who will conduct the environmental monitoring studies according to the issues stated in the EMP under the control of the Municipality and Environmental Engineer, will present the results to the Municipality with environmental monitoring reports. The Municipality will evaluate the monitoring reports which are presented by the Contractor in terms of related environmental measures. Moreover, the Municipality will keep a copy of the environmental monitoring reports and submit another copy to the field office of the Contractor to present it to authorities in the controls that will be made by Ankara PDoEU. When non-compliance is detected by the PDoEU, the Contractor will resolve the situation and declare it to the Municipality. Within the context of this EMP, the task distribution concerning anticipated activities in the construction phase is presented in Table 7-3. Table 7-3 Task Distribution Related to the Construction Phase EMP Requirements (R: responsible, S: supervisor, A: assistant) Task Item Contractor Municipality 1 Environmental Quality Monitoring R S 2 Training of Key Personnel R S Training of Staff R S Corrective Actions R S Internal Monitoring R S Reporting R S Relations with the Media A S3 Handling Complaints R S 1 Measures should be conducted by the qualified institutions and establishments according to the national legislation. 2 Training activities will be carried out in coordination with the environmental engineer. 3 Relations with the media are the responsibility of the Municipality as a requirement of general implementation rules of public investments. This forbids the Contractor from arranging a direct meeting with the media. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 59/62 7.6.2 Operational Phase As the proposed environmental monitoring works for the operation phase are very limited and the organizational structure of the operational staff is not certain yet, there is no detailed proposal for institutional arrangements at the moment. In short, there should be one HSE officer in the organizational structure of the Municipality who will be responsible for following up the EMP requirements, related to the operational phase, and for coordination with the environmental engineer to be appointed by Municipality. 7.7 Consultation with NGO’s and Project Affected Groups A public relation mechanism should be set up and applied throughout the construction and operational phases of the Project. In this respect, local people and NGO’s as well as local authorities will be informed about the Project progress. Hence, any public objection that might be raised by local people due to lack of information could be prevented and good relations between the local people and the Municipality as well as contractors can be established and maintained. However, there is no complaint about the Project by local people or NGO’s until now. Any complaint rose by local people or NGO’s will be recorded and followed up whether or not corrective actions, if necessary, are taken. Therefore, a log book for such complaints will be available at the site office (during the construction phase) or power plant administrative building (during the operational phase). 7.7.1 Construction Phase During the construction phase, periodic public consultation meetings (PCM) will be held in Beypazari. In these meetings, the relevant stakeholders (local people, representatives of local NGO’s as well as local authorities) will be informed about the progress of the project development. A separate section will be allocated for the public relation activities in the environmental monitoring reports to be prepared by the Environmental Engineer in the context of the Project The first PCM before the construction of the Project was held on 09.06.2010 at 14.00 in the Beypazari Public House. Many people from Beypazari district center attended the meeting. Detailed information about PCM is given in Appendix-C. The second PCM was held on 10.01.2011 at 11:00 in the Beypazari Public House. In this meeting, local people, local authorities and representatives of WB and BoP are informed about the specifications of the Project such as units operations and processes. Information being provided in the second PCM about the construction period of the Project is described below:  Construction and commissioning period of the Project is estimated to be 2 years.  Domestic solid waste amount is calculated as 94 kg/day. Beypazari WWTP Project EIA Report August 2013 Project No.: 128.02 60/62  Waste batteries/accumulators, tyres and medical wastes will be collected and disposed by licensed firms.  Hazardous wastes will be temporarily stored then will be collected by licensed firms.  Dust preventive measures will be taken such as speed limitation and watering during the construction.  Expected noise will be 59.34 dBA in the nearest sensitive receptor.  Occupational Health and Safety measures will be taken to prevent any dangerous situation for workers. 7.7.2 Operational Phase During the operational phase of the project, regular PCMs should also be held. During PCMs, minutes of meeting will be taken together with a list of participants who will sign an attendance sheet. These records should be kept by the Municipality.
