Baseline conditions were established for the project area through field measurements for air quality, noise, hydrology, hydrogeology, geology, soil quality, and terrestrial ecology. As a consequence of its previous use as a military training ground, the site has been highly intervened and has significantly lost many of its original natural characteristics.
Resource Efficiency
Drinking water during the construction and operation phases of the project will be provided from the Elazig municipal water system. A 150 liters/day per capita consumption rate was estimated yielding a daily water requirement of 300 m3/day during the peak time of the construction. Water will be required for other construction-related activities such as dust suppression, spraying concrete, site clean-up, etc. An additional 210 m3/day water consumption rate has been calculated for construction activities. During the operation phase, there will be water uses related to general domestic and sanitary use, food preparation, sterilizers and autoclaves, etc. The water consumption rate for the Elazig IHC was calculated based on the daily water consumption value per bed (between 1.25 m3 and 1.60 m3) according to data for large hospitals in the United States (US Energy Information Administration, 2007). Thus, the water consumption is estimated to fluctuate between 1,297 and 1,661 m3/day. Municipal water supply has been deemed adequate to fulfill these estimated requirements.
In the operational phase of the project, electricity will be produced on-site via a tri-generation plant. This plant, with total rated capacity of 5.5 megawatt (MW), and a three boiler system with rated capacity of 10 MW each will supply all energy, heating, and cooling needs during the hospital operation. According to the yearly electricity consumption data for large hospitals in the US (250 kWh/m2), the yearly electricity consumption of ELZ IHC was calculated as 50,750,000 kWh. Diesel fueled emergency generators located within the central energy plant will be used to provide backup power supply for the hospital buildings. Each generator will be equipped with a day fuel tank that will be sized to operate for a minimum of 2 hours continuous operation at full load. The main energy source during construction will be diesel fuel for construction equipment, vehicles and generators to supply construction camp with electricity; the ESMP includes procedures to safely handle and store diesel fuel on site.
Energy efficiency will be considered in the design and operation of the project. Energy and water resources management plans have been recommended as part of the ESMS, in conformance with PS3, to optimize resources use.
Wastewater
Elazig’s domestic wastewater is collected and undergo primary (mechanical) and secondary (biological) treatment at the Elazig Municipality Wastewater Treatment Plant (WWTP) where ultimately all wastewater produced by the project during construction and operation will be treated. The existing capacity of the WWTP is 69,984 m3/day and, although it has not reached its maximum capacity, according to the Elazig Municipality Director of Environmental Protection the current design capacity and efficiency of the plant are inadequate for projected urban growth. As reported by Elazig Municipality, a modular treatment system with 50,000 m3/day capacity will be added to the existing WWTP with the objective of increasing its capability to 120,000 m3/day. The WWTP expansion is expected to take place concurrently with the project construction.
During the project construction and operation phases the total daily domestic wastewater generation of the project is estimated to be 510 m3/day and 1,661 m3/day respectively, which will be within the current treatment capacity of the Municipality plant. ELZ Saglikwill obtain a wastewater connection permit since all domestic wastewater during all project phases will be discharged into the existing municipality sewer lines in accordance with Waste Management Regulation.
Wastewater from medical wards and operating theaters (e.g. body fluids and excreta, anatomical waste), laboratories (e.g. microbiological cultures, stocks of infectious agents), pharmaceutical and chemical stores; and cleaning activities (e.g. waste storage rooms) will be collected via different piping systems and monitored before discharged into the sewer system.
Wastewater contaminated with radioactive substances during operation of the health campus will be collected separately and monitored for the residual activity prior to being discharged into the sewer system as low activity liquid waste per conditions set under the Regulation on Wastes Generated upon Usage of Radioactive Substances. Approval from the municipality will be required prior to discharging radioactive wastewater, per the referenced law. This authorization will be obtained during the licensing process. As per WBG EHS Guidelines for Health Care Facilities, the capacity of the municipality to receive this type of wastewater must be confirmed and a wastewater management plan completed.
Solid Waste Management
The production of non-hazardous and hazardous solid waste, including medical and radioactive wastes, is expected throughout different phases of the project. Thus, a project-specific Waste Management Plan covering site preparation, construction and operation phases of the hospital has been completed. The plan identifies all waste streams and some anticipated waste quantities, describes transportation and disposal requirements, and outlines waste management responsibilities. All waste streams will be managed and disposed of in accordance with Turkish regulation and WBG EHS Guidelines for Health Care Facilities.
Site preparation and construction include soil excavation activities that have already started at the project site. It is estimated that 620,000 m3 excavation wastes will require off-site disposal, roughly 201,000 m3 has been excavated to date. Approximately 127,000 m3 of the excavated material has been transferred to an approved excavated material storage area of Elazig Municipality, located about 14.5 km away from the project area, while the rest is being stored on site to be used as filling material during construction. Soil sampling conducted at the project site during the ESIA phase did not show any sign of contamination.
Waste generation during construction will include contaminated soils, sanitary and domestic wastes, and clean-up materials from accidental spills. The estimated domestic waste generation during the construction phase is 2.2 tons/day. Domestic waste is stored in waste containers, collected by the Elazig Municipality, and transported to the municipal landfill 30 km from the site. Estimates for domestic solid waste generation assume that the hospital will produce approximately 2.4 tons/day during the operation of the Elazig IHC.
During the operation phase, infectious and pathological waste and other hazardous wastes from laboratories will be segregated at source, collected in designated containers, appropriately stored on-site, then transported and disposed of by authorized contractors. Collection and disposal of the medical wastes will be done in line with the Regulation on Medical Wastes Control. Once the necessary protocols are completed, medical waste disposal from operation phase will be made to Elazig Medical Waste Treatment Sterilization Center. The annual medical waste generation for Elazig IHC was estimated at 322 tons (or 882 kg/day, assuming 1,038 beds).
The radioactive waste stream is expected to include residual radionuclides proceeding from unused liquids used in radiotherapy or laboratory research; contaminated glassware, packages or absorbent paper; urine and excreta from patients treated or tested with unsealed radionuclides, etc. Clean-up materials such as spill kits will also be managed as hazardous waste.Disposal will be done by companies authorized by Turkish Atomic Energy Authorization in accordance with regulation on Secure Transfer of Radioactive Materials and the Regulation on Management of Radioactive Wastes. In addition to Turkish regulations, the project will follow waste management practices stipulated in WBG general and EHS guidelines for Health Care Facilities.
As per the ESAP item 6, the company shall provide IFC with documentation on the status of the existing and proposed improvements on wastewater treatment facility and landfill site of the Elazig Municipality. Documentation should include confirmation that existing systems are capable of handling all wastes streams produced by the Elazig IHC, and evidence of necessary approval for the discharge of radioactive liquid wastes has been obtained.
Air Emissions
Main sources of air pollution during the construction phase were identified as excavation works, movement of vehicles, and engine emissions from exhaust gas from construction equipment and road traffic. Principal pollutants resulting from these sources are particulate matter (PM) from soil excavation and removal; and nitrogen oxides (NOX), sulphur dioxide (SO2) and carbon monoxide (CO) from exhaust of vehicles. Measurements for PM10 to establish baseline conditions and a dust dispersion modeling study were completed and potential impacts within the study area calculated. Test values are significantly below the associated limit values stipulated in the national regulations (Industrial Air Pollution Control Regulation – IAPCR - and Regulation on Assessment and Management of Air Quality - RAMAQ), European Union (EU) directive and World Health Organization (WHO). Additionally, a vehicle movement analysis was performed to estimate baseline conditions for NOx, SO2, and CO emissions associated with construction activities. All values were under the maximum permissible limits in the national regulation (IAPCR). Actual values will be monitored during construction and compared to modelled results. Mitigating measures will be implemented should recorded values exceed project and/or legislative standards.
Impacts on the air quality during the operation phase will be mainly related to the emissions from the tri-generation plant and boiler system. A dispersion modeling study was undertaken for NO2, the most significant emission source from these systems. Hourly and annual values of NO2 estimated from the tri-generation system are significantly below the associated limit values defined in the national regulations (IAPCR and RAMAQ), EU Directive and WHO Guidelines. Thus, impacts from pollutant and dust emission to the atmosphere is expected to be minimal during all phases of the project. Monitoring and implementation of mitigation measures for the control of exhaust from all vehicles will be adopted per the ESMP.
GHG Emissions
According to ESIA, generation of greenhouse gas emissions during the operation of the tri-generation and boiler systems is expected to be 75,187 tons CO2 equivalent per year; therefore, the project will be required to quantify and report to IFC the direct and indirect emissions annually.
