Resource efficiency
Resource consumption such as water and fuel consumption are monitored as per FTA’s E&S Management Plan (ESMP). FTA developed and is implementing a certified ISO 50001 energy management system. FTA follows a systematic approach in achieving continual improvement of energy performance and monitors energy efficiency with set key performance indicators (KPIs) focusing on electricity conversion efficiency for natural gas use (%) and electricity use (kWh per passenger). Examples of energy efficiency improvements include the use of LED lighting and continuous monitor of heating and cooling. For expansion works, the Terminal 2 building is designed as per LEED Gold certificate requirements.
FTA operates a trigeneration plant to partially meet the electricity, heat and cooling power needs of the airport and holds the necessary license for this operation from Republic of Türkiye Energy Market Regulatory Agency (EPDK). The plant has total of 8 MW installed capacity and runs with natural gas and alternatively with liquefied natural gas (LNG). Nearly 50% of AYT’S energy demand has been met by the trigeneration unit, share of which decreases to 45% during summer period. According to the concession agreement, FTA is allowed to install a rooftop solar power plant with maximum 4 MW capacity for which feasibility studies are still ongoing.
Greenhouse Gases
Direct ground-based AYT airport GHG emissions are caused by fuel consumption from on-site combustion including diesel, natural gas and petrol use, self-generated electricity form trigeneration unit and purchased electricity. Indirect emissions are associated with fuel combustion in aviation (LTO), electricity supply to third parties from both purchased and generated electricity and fuel consumption for ground vehicles. Based on Antalya Airport 2021 Carbon Footprint report, in 2021 the total GHG emissions associated with the airport were 270,260 tCO2-eq out of which 14,230 tCO2-eq was reported under direct GHG emissions’ scope (Scope 1 and Scope 2). This total figure is 37% less than the pre-COVID 2019 emissions (433,570 tCO2-eq). The ESIA estimates that the GHG emissions associated with the airport’s operation will reach to 591,760 tCO2-eq by 2027, out of which 30,560 tCO2-eq will be direct GHG emissions (Scope 1 and Scope 2).
FTA is undertaking carbon assessments annually as part of the ACI’s Airport Carbon Accreditation (ACA) scheme. The airport has a Carbon Management Plan (CMP) in place which is revised every three years including assessing the GHG reduction opportunities. As per ESAP 10, FTA will continue to calculate and monitor GHG emissions annually in line with ACA and IFC guidance. In addition, FTA will achieve and maintain the certification to Airport Carbon Accreditation Level 4 and disclose long-term absolute GHG reduction target in line with ACA Level 4 requirements.
Update 2024: The ESIA estimated 7,410 tCO2-eq will be avoided due to reductions in purchased electricity, including the installation of a 4 MW solar PV. This is a conservative estimate as there is a planned increase in PV installed capacity to 5.8 MW over the project implementation. ESAP #10 listed in the paragraph above has been updated under ESAP #5 by which FTA will adopt a GHG Calculation Procedure to ensure that it continues calculating, monitoring and publicly disclosing GHG emissions annually in line with the ACA scheme and IFC guidelines.
Pollution Prevention
Air Emissions and Noise
For current operations, FTA holds an air emission permit valid until August 2024. The latest emission monitoring report from 2020 confirms that utilities on site, i.e., trigeneration and heating system, comply with the local regulation.
For project operations, the air modelling study in the ESIA concludes that overall impacts of particulate, SO2, CO and NO2 emissions will not be significant. On the other hand, volatile organic carbon (VOC) national regulation limit values are predicted to be exceeded in terms of both hourly and long-term limit values.
As per ESAP #11, FTA will cooperate with DHMI and fuel operators, in a manner commensurate with the client’s control and influence over the third parties to initiate VOC monitoring and analysis both at the current and new fuel farm area to understand the likely contributions to VOC concentrations and if the new fuel farm has the potential to create VOC exceedances as predicted by the modelling. The scope of the analysis should also include monitoring impacts of the new fuel farm on the nearby receptors such DHMI state housing.
The project has a Dust Management Plan that includes regular water spraying during construction hours (and more frequently during dry days), speed limits for trucks, stabilization and wetting of soil piles. To address air quality impacts from the construction FTA will revise and develop, as necessary, (ESAP #1 and #2) and implement operation and construction Air Quality Management Plan covering additional mitigation measure related with dust and other emissions resources for construction phase
Noise monitoring and impact due to airport operations are discussed under PS 4 section.
Update 2024: As per the latest monitoring results from 2023, FTA remains compliant with the local regulation and WBG General EHS Guidelines. The original ESAP #11 above has been updated under ESAP #6, by which FTA will cooperate with DHMI and fuel farm operator, in a manner commensurate with the client’s control and influence over the third parties, to assess VOC-related impacts and corresponding mitigation measures. The project has a construction-phase Dust Management Plan and is in the process of completing the development of an Air Quality Management Plan (ESAP #1).
Soil and Groundwater
The existing associated fuel farm of the airport with 37,000 m3 capacity is operated by three different fuel suppliers. All suppliers comply with EI/JIG Standard 1530 Quality assurance requirements for the manufacture, storage, and distribution of aviation fuel to airports (A4), for which yearly audits are conducted. Within the expansion project, existing fuel farm will be relocated to the northern side of the airport and the capacity of the new fuel farm will be 80,000 m3. Before the decommissioning starts, FTA will initiate the process and cooperate with DHMI and fuel farm operator to conduct leakage test, soil sampling and analytical testing in the farm locations (ESAP #12a).
After the design of the new fuel farm is completed and before construction arm starts the FTA is required (ESAP #12b) to conduct soil quality analysis and to undertake QRA (ESAP #12c) to demonstrate the planned siting and the safety measures incorporated into the design provide adequate protection for the population and structures in the surrounding environment. The new fuel farm, to be operated by an independent private operator, will be designed as to comply with the EI/JIG Standard 1540 for design, construction, commissioning, maintenance and testing of aviation fuelling facilities and the provisions of the Seveso Directive.
For current operations, potable water, irrigation water and cooling water for power facilities are fully sourced from 12 groundwater wells within the project site., FTA with cooperate with DHMI, as necessary, to obtain valid usage permits for all wells managed by FTA.
Water needs for the construction works, including sanitary use by workers, concrete batching and dust suppression is estimated to be 650,000 m3. Water will be supplied to the construction site with the existing water infrastructure with three new water tanks in total capacity of 2,600 m3 to be allocated.
Review of available documentation suggested that the annually extracted groundwater amount by FTA (722,501 m3 in 2021) is lower than the total permitted amount (814,009 m3) regardless of the purpose of the use. Considering that the estimated annual increased water demand of the airport (952,648 m3 in 2022 and 1,091,434m3 in 2023) will be higher than the permitted annual water abstraction amount, new wells will be needed to supply the necessary water. DHMI will be responsible from applying to State Hydraulic Works (DSI) and obtaining the required additional groundwater use permits. However, since the wells in the project site are used by different entities including DHMI, possible impacts of increased groundwater withdrawal on the replenishment capacity of the aquifer and eventual negative impacts for the nearby community members using the same water wells will be established, permitting requirements will be identified and initiated accordingly and any mitigations required will be agreed with DHMI and relevant stakeholders (ESAP #13).
Withdrawn groundwater is treated preliminarily through softening procedures and water quality is monitored monthly as per the requirements of the local regulation, Regulation on Water Intended for Human Consumption. The same procedure will continue to be applied during the construction and operation phases of the project.
Update 2024: The original ESAP #12a above has been updated under the new ESAP #7, by which FTA will initiate the process and cooperate with DHMI and fuel farm operators to conduct leakage tests, soil sampling, and analytical testing in the farm locations to ensure that the decommissioning of the existing fuel farm is consistent with the FTA’s ESMS and local requirements.
As per the original ESAP #12b above, before the start of construction activities of the new fuel farm, the FTA conducted a soil quality analysis which confirmed that all parameters were within the limit of the local regulation on Control of Soil Pollution and Point Source Polluted Sites, concluding that there is no imminent hazard risk to any receptor. In addition, a water quality assessment from a well in the new fuel farm area was conducted, which confirmed that there is no groundwater pollution in the area. As per the FTA’s guidance, DHMI received a permit to earth-fill the area as an additional mitigation measure.
As per the original ESAP #12c above, FTA has undertaken a Quantitative Risk Assessment in coordination with the new fuel farm operator to demonstrate that the planned siting and the safety measures incorporated into the design provide adequate protection for the population and structures in the surrounding environment. The client has also commissioned an independent audit of the design and construction of the new fuel farm to ensure that the facility is built and operated in strict adherence with internationally recognized E&S and safety standards, including the EU Seveso Directive, which is focused on control of major-accident hazards involving dangerous substances, as well as the EI 1540, which is an international standard for the design, construction, commissioning, maintenance and testing of aviation fueling facilities. Under the new ESAP #8, depending on the results of the independent review, the client will implement mitigation measures, if any are identified by the audit, to address gaps in design and operational procedures.
The airport's annual water demand due to expansion will be higher than the permitted annual water abstraction amount (814,009 m3 in 2022). Hence, new wells will be needed to supply the necessary water. DHMI will be responsible for applying to the State Hydraulic Works (DSI) and obtaining the required additional groundwater use permits. However, since the wells in the project site are used by different entities, including DHMI, FTA will monitor groundwater abstraction rates and changes in water levels in the established monitoring network to ensure potential impacts on third party water users are identified, and any mitigations required will be agreed with DHMI and relevant stakeholders (updated ESAP #9).
Withdrawn groundwater is treated preliminarily through softening procedures, and water quality is monitored monthly as per the requirements of the local regulation, Regulation on Water Intended for Human Consumption. As per the updated ESAP #9, FTA will continue to conduct regular water quality analysis for all wells in line with the operational Water Management Plan, and any exceedances detected will be mitigated with corrective actions.
Wastewater Management
AYT has an operational wastewater treatment plant with a total capacity of 4,500 m3/day. The wastewater generated at the airport is treated on-site and discharged to deep soil. As per local water pollution regulation, effluent quality is controlled by measuring pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Suspended Solids. As per ESAP #14a, FTA will update Wastewater Management Plan for operation activities in line with the national requirements, World Bank Group EHS Standards and measures identified in the ESIA Report; the Wastewater Management Plan will include monitoring of total nitrogen (TN), total phosphorus (TP).
Within the project scope, the capacity of the current wastewater treatment plant will be increased, and two additional treatment plants will be built to treat the increased volume of wastewater. The exact location and design of the plants are still under consideration.
During construction works, the EPC contractor is responsible for managing wastewater generated on site as per its Waste Management Procedure (2022), PS3 and WBG EHS Guidelines for Airport.
Update 2024: ESAP #14a is now ESAP #10 with no changes.
Hazardous Material and Waste Management
Hazardous materials, which are expected to primarily include oil and fuel from aircraft and ground service vehicle maintenance, will be stored in designated areas in accordance with the national requirements and standards, relevant WBG EHS Guidelines and good practices guidelines to prevent any spillage on the site. As there is no dedicated site-specific Hazardous Materials Management Plan for the construction phase FTA will ensure that ATS develop (ESAP #1 and #2) a site-specific Hazardous Materials Management Plan for both construction and operations phases defining specific storage, transport and conditions based on hazardous materials chemical-physical properties and amount of hazardous materials present.
The airport operation contributes to generation of both hazardous (e.g., sludge from the wastewater treatment plant, waste oil, waste batteries and waste electrical and electronic equipment (WEEE)) and non-hazardous waste (e.g., organic waste, packaging waste, and waste tires). The FTA managed terminal operations generate mainly non-hazardous waste, which is managed as per the existing waste management plan. To strengthen the practice, as per ESAP #14a, FTA will update and implement a Waste Management Plan (to include temporary storage of the hazardous waste) for operation activities in line with WBG General EHS Guidelines to monitor and record estimated and actual waste volumes as well as to define waste treatment/disposal options and disposal routes, with preference given to waste recycling and reuse of material where possible.
Construction waste, both hazardous and non-hazardous, will be managed as per the EPC contractor’s Waste Management Procedure (2022). As per ESAP #14b, this construction Waste Management Procedure will be revised and implemented to be in line with the national and international standards including wastewater site-specific mitigation/control measures and monitoring. Hazardous construction waste including contaminated materials (e.g., asbestos) due to maintenance and repair will be managed by ATS and stored on the hazardous waste temporary storage area designated by FTA, and then disposed of by licensed subcontractors.
Update 2024: As per the original ESAP #1 and 2, the EPC contractor developed a site-specific Hazardous Materials Management Plan for construction to be implemented during the construction phase. Ahead of the start of the operations phase, FTA will finalize the operational Hazardous Materials Management Plan defining specific storage, transport, and conditions based on hazardous materials' chemical-physical properties and the amount of hazardous materials present (updated ESAP #1).
ESAP 14b above has been replaced by the updated ESAP #11, by which the FTA will update and implement a Waste Management Plan to include temporary storage of hazardous waste for operation activities in line with WBG General EHS Guidelines.
