Resource Efficiency
The company aims at developing and implementing an ISO 50001 energy management system for ANT which will result in more efficient use of energy. As a first step towards that objective, the Company will perform energy efficiency audit for ANT and, based on outcomes, define corrective actions (ESAP item # 9).
Greenhouse Gas (GHG) Emissions
The current operation at the airport contributes about 41,700 t CO2-equivalent per year in terms of GHG emissions. VINCI Airports’ environmental policy (AIRPACT) commits to achieving Airport Carbon Accreditation for every airport in the portfolio, and the Company will work to attain this commitment at ANT as well. Upon replacing the existing heavy-fuel boiler plant with the new combined cooling, heat and power plant included in the works program, the CO2 emissions of ANT will be reduced by about 15,400 t CO2 yearly. VINCI is also planning a further reduction of about 2,500 t CO2 yearly upon the installation of the planned photovoltaic system by 2021.
Pollution Prevention
Air Emissions
The main stationary air emissions source associated with ANT operations is represented by the heavy oil fuel-fired boiler plant. The boiler plant consists of three operational boilers with the capacity of 9.3 MW each. ANT performs boiler plant emissions monitoring once a year, at the beginning of the heating season. As part of the project works, the Concessionaire will replace, by 2020, the existing plant with a cleaner and more efficient natural gas-fired system (consisting of three boilers) supplemented by a trigeneration unit with an output of 1,560 kW electrical and 1,580 kW thermal associated with an absorption chiller of 1,230 kW to generate electricity, heating and cooling. The total capacity of the trigeneration plant will be 44 MW thermal. As part of the upgraded operational management system, the Company will establish an environmental monitoring program including air emission monitoring in line with Serbian regulation and applicable and relevant World Bank Group EHS Guideline requirements (ESAP item #5).
Liquid Effluents
Sanitary wastewater generated by ANT is discharged, without treatment, into a municipal sewer system, which discharges the wastewaters into the Sava River. The storm water runoff from the paved areas and de-icing effluents are discharged, without pre-treatment, into Galovica Creek, a Sava River tributary. As per ESAP item # 10, VINCI will: (i) design and install a wastewater treatment plant, consisting of a moving bed bioreactor, for treatment of sanitary wastewaters with an approximate capacity of 750 m3/day; (ii) install a containment pond for storm water; (iii) install oil-water separators to treat storm water runoff from areas with potential for hydrocarbon spills; and (iv) install a containment pond for collection and proper treatment of wastewater from the de-icing platform.
As part of operational ESMP, the Concessionaire will define and implement a wastewater monitoring program in line with the Serbian legal requirements and applicable and relevant World Bank Group EHS Guideline requirements (ESAP item #5).
Noise
As mentioned above a relevant number of residential houses, including some unplanned settlements, are located in proximity of the airport. These residential properties may potentially be exposed to noise impact from airport operations and may require implementation of noise prevention and control measures.
Aircraft landing and taking off are the main source of noise pollution. As per Noise Protection Act (OG 36/09 and 88/10) and Air Transport Law of Serbia (OG 66/15), adequate response to monitor and mitigate impacts of airport generated noise is the responsibility of several stakeholders, including public authorities e.g. Serbian Ministry of Transport, Serbian Ministry of Environmental Protection, Serbian Agency for Environmental Protection, Civil Aviation Directorate (CAD), air traffic control, airport operator, and airlines.
IFC was informed by CAD that noise mapping for ANT and the relevant noise mitigation plan in line with the requirements of the European Union Directive 2002/49 will be finalised by the end of 2020 by the Ministry of Environmental Protection and Ministry of Transport. As per information made publicly available by CAD, noise mitigation measures for ANT and flight operations, which are currently enforced, include take-off restrictions in the direction of Belgrade city and provision of aircraft noise certificates by airlines for approval by CAD.
As part of the actions under its responsibilities and control, the Concessionaire as ANT operator will prioritize the development and implementation of 24/7 noise monitoring program. Noise will be monitored using permanent noise monitoring stations and other tools such as departure monitoring, flight track profiles, use of the PCA (Point of Closest Approach) (ESAP item #11). As part of its commitment to noise pollution abatement and control, the Concessionaire will develop a noise mitigation plan for ANT in close cooperation with CAD (ESAP item #11). The noise mitigation plan will be informed by the adoption of a Balanced Approach as required by the relevant EU directive (Directive 2002/30/EC of the European Parliament and of the Council of 26 March 2002 on the establishment of rules and procedures with regard to the introduction of noise related operating restrictions at Community airports). The EU Balanced Approach for managing airport operations noise comprises four principal elements: making airplanes quieter by setting noise standards; managing the land around airports in a sustainable way; adapting operational procedures to reduce the noise impact on the ground; and, if required, introducing operating restrictions. The noise mitigation plan among others will take into consideration the following mitigation actions: (i) in close collaboration with Air Traffic Control and other key stakeholders listed above aircraft takeoff and landing routes will be reviewed to take into account the type of aircrafts in use and the current situation in terms of local sensitive noise receptors, including residential areas that have gradually encroached towards the limit of the airport; (ii) work with Air Traffic Control to review the flight zones and introduce more accurate methods and measures of aircraft control; (iii) airport operating times will meet governmental regulatory requirements; (iv) where noise is attributed to airside or groundside operations, distance attenuation and screening will be adopted where practicable; (v) all equipment e.g. auxiliary power units and ground support vehicles will be maintained in good working order; performance specifications for noise for new equipment, wherever possible, to ensure that the procured item is noise controlled; (vi) engine idling on the terminal aprons will be kept to a minimum; (vii) noise monitoring stations will be established based on predominant wind directions; noise sources; flight path, and population and noise contour modeling will be performed; (viii) a grievance management and monitoring system will be established, including the identification of designated person responsible for complaint investigation and resolution, and will be made publicly available; (ix) based on the monitoring results, sound insulation will be installed at selected households that are exposed to excess noise, if needed. The noise mitigation plan will clearly define roles and responsibilities of the company and other relevant parties and will define all necessary coordination mechanisms among relevant stakeholders for the implementation of the measures.
The Concessionaire will promote the establishment of an ANT Environmental Advisory Committee (ESAP item #12) and will actively coordinate with relevant Serbian authorities and stakeholders for the implementation of the noise mitigation plan.
If the actions defined in the noise mitigation plan are not sufficient to meet noise standards that will be established by the GoS and will be applicable in the future, in accordance with the Air Transport Law (OG 66/15) the Concessionaire, as ANT operator, will be authorized to apply for the consent by CAD to implement and collect a noise surcharge for airlines (in accordance with Article 202 in the Air Transport Law) to offset the cost of any compensation or noise mitigation program.
The noise aspects of construction program will be addressed by construction ESMPs that will be developed by contracted EPC contractor as per ESAP item # 4
Solid and Hazardous Waste Management
A waste management plan for ANT was approved by Serbian authorities in 2014. The E&S due diligence found that management practices at the airport for both hazardous and non-hazardous wastes require improvements. VINCI, as part of works program, will improve solid waste management at ANT by: (i) construction of a waste sorting building, (ii) construction of two non-hazardous waste storage areas, (iii) construction of a hazardous waste storage area, and (iv) update of the airport waste management plan in line with the local legal requirements and relevant and applicable WBG EHS general and sector guidelines as per ESAP item #13.
Construction waste generated by the works program will be managed by contracted EPC Contractor under the construction ESMP as required under the ESAP item # 4.
Hazardous Material Management
Hazardous materials used at ANT are mainly hydrocarbons, oils, lubricants, metal degreaser and de-icing agents, and fuels represent the main hazardous materials stored and handled. The airport operates a fuel tank-farm located in the central part of the airport premises. It comprises eight above-ground storage tanks and two underground storage tanks, with total capacity of 990.5 m3. Upgrade of the fuel tank farm is part of the works program. Based on hazard assessment outcomes, the Concessionaire will develop and implement a hazardous material management plan and spill prevention and response plan that are commensurate with the potential risk present. This plan will be part of the operational ESMP as per item # 5.
Historical Pollution
Areas of concern for potential historical pollution at the ANT include: the fuel tanks farm, former wastes storage area, old transformer stations, current solid waste open storage area, heavy oil-fired boiler plant, and equipment maintenance areas. The company will address E&S risk, particularly in respect to historical liabilities e.g. soil, groundwater contamination, as required and under the conditions agreed with the GoS. The Concessionaire will ensure that an environmental site assessment (ESA) is carried out. In that respect, at the time of appraisal, a specialized consultant (ERM) performed a Phase I ESA in accordance with the scope of ASTM International Standard E-1527-13. The Phase I ESA identified four areas at the site with the presence or likely presence of hazardous substances or petroleum products in, on, or at a property and eight areas of potential concern. A Phase II ESA in accordance with ASTM E1903 will be carried out to provide information on the site environmental conditions. Based on Phase II ESA outcomes, the company will prepare and implement required decontamination activities in accordance with Serbian legal requirements as per ESAP item #14.
Management of Grassed Areas
Pesticides are used at ANT for management of grassed areas for bird deterring and bird strikes control purposes. The activity is performed based on International Bird Strike Committee (IBSC) recommendations, including a long grass policy. Proper selection, storage and handling of herbicides following the hazardous materials storage and handling management practices in the General EHS Guidelines can prevent / mitigate risks of soil, surface and underground water contamination. Therefore, the Concessionaire will perform an assessment of the current use and management of pesticide, herbicides and other agricultural chemicals and based on outcomes develop and implement an integrated plan for the management of grassed areas, as per ESAP item #15.
