ENVIRONMENTAL MANAGEMENT PLAN
1. Objective and Scope
Despite of the fast pacing technological developments that the world is facing, energy is still the absolute input for the industry. Energy need tops the indispensable needs of the industrializing societies.Energy investments that have not been made at the right time and not been planned well enough make thedeveloping countries shoulder a heavy cost burden and impede the optimum usage of already limited resources. Such countries usually have limited fossil-derived resources that harm nature whereas developed countries, no matter if their resources are limited or not, enhance their daily usage capacity of alternative and renewable energy continuously.
Turkey’s total energy demand clearly differs from the possible and planned local energy production. According to the plan made, the energy demand and the trend of national energy production is as below described. As it can be seen primary energy demands of Turkey and national production are examinedit can be concluded that the production gap is at such an important degree and at an increasing value.
The subject of the project is regulator and hydroelectric power plant (river type). The location of the project area is chosen at Darca Narrow of Sakarya River in the Küçükyenice Villageborders ofthe Gölpazarı District of the province of Bilecik. Environmental Management Plan (EMP) comprises some important environmentalimpact reduction criteria and defines some monitoring and institutional needs for the application of EMP. Impact reduction and monitoring activities taken into consideration with respect to different stages of the project are as follows:
-Pre-construction (project planning and design)
-Construction (all of the construction works)
-Water holding
-Operation
At the operation stage, the details of the criteria will be practiced and developed by the line organizations and project parts.
2. Institutions and Organizations Responsible for Hydroelectric Power Plants
Darca Regulator and HPP Project’sline organizations are State Hydraulic Works (DSİ) and Energy Market Regulatory Authority (EPDK). Considering the Project, Electricity Generation License should be taken from EPDK (Energy Market Regulatory Authority), and Water Use Rights Agreements should be made with the General Directorate of DSİ for Darca HPP. “EIA Exemption Certificate” has also been obtained within the framework of EIA Regulation.
3. Impact Reduction Plan
Regarding the project, some impacts are unavoidable, some can be reduced to the minimum and some can be altered.
With respect to impact reduction planning, the pre-construction stage where the project’s some major environmental impacts will be defined after research, design and planning studies, and then these impacts will be avoided, reduced to minimum or compensated through efficient project designing, management or action plans that will be prepared by the responsible parties’ coordination,including the consultation with public and withthe parties.
Similarly, the construction stage is composed of developing appropriate management tools, applying the action plans which will be prepared at the former stage, developing these plans in detail, establishing a cooperation and a coordination in between the parties and the public, and performing the construction work according to the final design of the project.
Erosion
Impact reduction measures will be taken for the erosion risk that construction and excavation works may cause, and for reducing the sediment load of the surface and river waters.
In order to reduce the risk of erosion and sediment flow derived of any and every excavation work, the measures cited below will be taken.
-Construction materials like stockpiles, concrete aggregates, filtering materials and sand will be handled appropriately.
- The excess of excavated surface material or the surface material that is not to be used continuously will be eliminated at a defined waste disposal site.
- The removed top layer of the soil from the construction site will be dumped at an appropriate area so that it could be used for further planting and forestation activities. The entire storage and waste areas shall be set to include drainage and control measures.
-The pile height of the material will be determined in accordance with the topographic conditions of the site. Neither the material nor the waste disposal site will be located on the gulley areas.
-On the higher altitude side, preventive dikes will be made to cut the speed of erosion derived from material and waste areas.
Landscape Plan and Top Layer Usage
Construction work might be harming the visual features of the area. The majority of the area will be flooded; therefore, the land shape will be changed. Apart from the construction of the water holding area, the construction of the regulator body in the HPP area, the site area itself, and the new roads for the respected settlement areas will be done. Following the completion of the construction, these areas shall be restored and landscape studies shall be carried out.
As the project continues, the top layer of the soil will be removed very carefully so that the impact caused by the construction will be reduced to minimum; then, the soil will be piled while the weather conditions are kept in mind. In order to protect the productivity of the soil, the piles will be slightly compressed. The top of it will either be covered with organic material or some primary plant species will be planted. The collected top layer soil gathered during the construction work will be used for land arrangement.
Air Quality
As the project continues, dust formation shall occur duringthe excavation works at the constructionstage. Measures shall be taken by the spraying method for the dust formation on the roads and limit values shall not be exceeded. Within the scope of the Project, the“Regulation on Control of Air Pollution Originating from Industrial Facilities” which came into force following its publicationin the Official Gazette numbered 26236 and dated 22.07.2006shall be respected.
In the calculation of the dust emissions that might be caused by the construction the estimated emission factor that is9,9 g/m2 per day of the semi-arid areas is taken. (Source: USAEPA). Excavation works was planned to take about 4 months.
Dust emission={9,9g/m2-day*(day/8hour)}*{21.920m2 /(4month*30day/month)}
Dust emission=226g/hr=0,226kg/hr
This calculated value is lower than the one that has once been at “Regulation on Control of Air Pollution Arising from Industries” Article 40 and Mass Flow Table 40.1 and is also less than 1,5 kg/hr limit value which has been indicated at the “Mass Flow Table 2.1 in Annex-2” in the “Regulation on Control of Air Pollution Originating from Industrial Facilities”that came into force by the amendment of the former regulation. Therefore, it is not required to carry out air modelling.
Besides, dust generation will be tried to be reduced to minimum levels by taking additional measures within the scope of the project regarding dust formation. In this respect, the following measures shall be taken:
-In the site, the places where equipmentis used and all the roads to the site will be sprayed with water regularly.
-Inorder to reduce the particulate matter emission that derives from the activities that generate dust (i.e. roads, which are not atabilized where construction equipments operate, excavation areas and any other places generate dust), water sprays will be used when and where possible.
-Speed limit shall not be exceeded during transportation.
-The material in the temporary piling areas will be levelled, humidified and compressed so that it will not be carried away again by wind. Watering material will be altered in order to provide for the most efficient humidification in accordance with the seasonal conditions.
-The trucks carrying construction materials like loose material, rock remnants and the like will be covered during the transfer.
-During the excavation and the filling works, dust will be prevented mainly by watering material. Loading and unloading will be done with care so that spreads will be reduced.
-If needed, truck tires will be cleaned so that mud is not carried onto the road.
-In order to meet the related emission standards, modern equipment and vehicles will be chosen for construction work.
- In order to secure the conditions and standardsin the Regulation on Air Quality Protection and to protect workers’ health, the machines and vehicles will be controlled in terms of exhaust systems and emission levels.
Noise
According to construction work noise modelling studies, even under the worst presumptions, thenoise level is within the limits even for the closest settlements. Noise controlling measures for the stationary and moving equipments are as follows:
-Installation and maintenance of noise reduction equipment will be done.
-Noise reduction materials will be used with other noise reducers and with earpieces and covers.
-Equipments operating quietly will be used as much as possible.
-When noise level is 85 dBA and higher, all construction workers will be provided with enough numbers of ear protectors.
Water Quality
Project area is situated on Sakarya River at the Darca Narrow.
Water will be used for two objectives. One is for the energy production as it was indicated in the scope of the project and the other is for meeting the needs of the staff working in the project.
Water Need for the Personnel;
For the construction stage of the project,the workforce is planned to be of 50 people. The water need per person is 150L/day (USLU, O.Prof. DEÜ. Faculty of Engineering, Department of Environmental Engineering, Lecture Notes of Treatment of Waste Waters, 2004). Given this information, the calculation is as follows: 50 people * 150 L/person-day = 7500 L/day = 7,5 m3/day. In addition to that, the facility is planned to have 14 personnel during operation stage. Accordingly, the water need at the stage of operation is 14 people * 150 L/person-day = 2100 L/day =2,1 m3/day
As per the articles of the “Regulation on the Pits to be Excavated where Sewer System Construction is not Possible” of the Ministry of Public Health and Welfare which came into force following its publication on the Official Gazette numbered 13783 and dated 13.03.1971, a watertight cesspoolis planned to be constructed at the site. Wastewaters collected at the cesspool will be drawn by a vacuum truck, transferred out of the river basin, and be discharged into the nearest sewage system. There shall not be any other wastewater generation other than domestic wastewater within the scope of the Project.
Water usage for energy purposes; within the scope of Darca Regulator and HPP Project, the waters collected by the regulator - which will be set on the Sakarya river - at the 74,18 m3/s flow rate will be transferred to Darca HPP. Thiswater, which will be used for the electricity production, will be discharged to the Sakarya River without any harm to its quality. Due to the operation of the regulator, the riverbed will lack some amount of water thatcauses effects on the aquatic species. In order to prevent such effects, some amount of water is going to be given to the riverbed as the minimum downstream flow.
Further, the activities in the riverbed combined with the activities in certain sites at the construction stage will augment the mud and sediment amount in the downstream parts of the river. These impacts shall be temporary, however, they might be significant in terms of sediment accumulation and mud with respect to downstream water quality. In concrete making water is used for the tempering of concrete and this process might lead to the generation of muddy wastewater with a high degree of pH. The following measures shall be taken concerning this issue:
-The water contaminated by concrete, paint, oil, solvents or silt will not be released to the land, nor will it be released to another river or drain line or to the soilfor filtering purposes.
-Necessary collection facilities shall be furnished in order to prevent water pollution due to construction activities.
- In the course of the road construction stage drainage facilities shall be built alongside the retention pool in order to seize the water flow released from the onsite concrete mixing works as well as the sediments carried by the water flow.
Waste Management
Within the scope of the project, the number of staff is planned to be first 50 and then 14, and these numbers are for the construction and operation stages respectively. As for the household solid wastes derived from staff members at the construction stage is calculated according to the value of 1,34 kg/person.day (Turkish Statistical Institute, 2006), the solid waste amount for 50 workers is as follows:
50 people*1,34 kg/person.day = 67 kg/day
Besides, 14 personnel will be employed during the operation stage. Therefore, solid waste amount during the operation stage is calculated as 14 people * 1,34 kg/person.day = 18,76 kg/day.
During the construction and operation stage, “Regulation on the Control of Solid Wastes” numbered 20814 and dated 14.03.1991 will be respected for the solid wastes the staff members produce. In order to facilitate the disposal and re-use of these wasteswithout posing a threat to the environment, they are to be collected separately in order to prevent environmental pollution and contribute to the economy, so to speak, all-necessary measures will be taken. In compliance with the conditions concerning the collection and transfer of solid wastes referred to in the regulation, solid wastes will not be dumped in areas where the environment is negatively affected. The wastes will be collected and kept in closed and standardwaste containers. Againin compliance with the regulation, they will be disposed by the municipality in closed vehicles that do not pollute the environment in terms of appearance, odour, dust, leakage and similar factor.
Excavated Material
During the land preparation and construction stage, excavation works will be carried out for the foundation of the structures. While excavating, the vegetative soil will be scooped off. The scooped off soil will temporarily be stored in accordance with the standards of related regulations. Following the completion of the construction works, it will be used for landscape purposes. Other excavation material apart from the vegetative soil will be stored within the site area, and it will be used for filling and levelling activities, the remaining part is again going to be used for landscape activities. The measures taken regarding this issue are as follows:
-Wastes will be collected systematically, and all of them will be separated either for recycling or for re-use (lumber, junk, metal etc.) or for disposal.
-No solid waste will be disposed at the site, nor will any of them be burried. Illegal dumping into the construction site, onto the roadsidesor into the river will never be allowed.
- The construction campsite will be kept clean and in order. The wastes carried by wind will be cleaned up daily.
-For every waste type mentioned above, separate storage containers will be available.
-Waste containers will be installed with covers or nets so that sweepers or wind will not carry away the waste and animals will be kept away from them.
-In order to comply with the conditions stated in KAKY (Regulation on the Control of Solid Wastes), household solid wastes will be collected and disposed at the nearest municipality waste area.
-Feasible excavation materials will temporarily be kept aside so as to be used for fillings and construction works.
Regulation on the Control of Packaging Wastes that came into force following its publicationin the Official Gazette numbered 26562 and dated 24.06.2007 will be strictly followed with respect to possible packaging wastes that might be generatedwithin the scope of the Project.
Asoil change, repair and maintenance of the vehicles will be carried out outside the project area, there is no possibility for the generation of hazardous wastes. When hazardous wastes are generated then theRegulation on the Control ofHazardous Wastes that came into force following itspublication in the Official Gazette numbered 25755 and dated 14.03.2005, the Regulation on the Control of Worn Out Tiresthat came into force following its publication in the Official Gazette numbered 26357 and dated 25.11.2006, and theRegulation on the Control of Soil Pollution that came into force following its publication in the Official Gazette numbered 25831 and dated 31.05.2005, and theRegulation on the Control of Pollution Caused by Hazardous Material in the Water and its Surroundings that came into force following its publication in the Official Gazette numbered 26005 and dated 26.11.2005 will be followed strictly.
As for the emergence of medical waste within the scope of the Project, theRegulation on the Control of Medical Wastes that came into force following its publication in the Official Gazette numbered 25883 and dated 22.07.2005 will be followed strictly.
Since the oil change of the vehicles will take place outside the project site, there will be no possibility for the generation of oil wastes. When generated, theRegulation on the Control of Oil Wastesthat came into force following its publication in the Official Gazette numbered 26952 and dated 30.07.2008 will be followed strictly.
