Environmental Responsibility Risks were identified, assessed and ranked at NIS level during 2017. Moreover, measures and necessary investments for their implementation were identified in order to eliminate high risks. In 2017, we continued to improve environmental protection by carrying out environmental projects and investing RSD 479 million in them. In order to reduce the emissions of SO2 into the air, the Pančevo Oil Refinery is in the process of implementing the project of ejector gas flushing at the Vacuum Distillation Unit. The installation of the CEMS system in the Hydrogen Unit will facilitate continuous monitoring of pollutant emissions into the air, which, in turn, will facilitate constant control of the unit operation. During 2017, we reached the number of 300 separators at petrol stations (at 89% of petrol stations), since 14 new separators for purifying oily wastewater were installed at petrol stations, and 5 existing separators were replaced during total reconstruction. There are plans to install the missing separators in the upcoming period. A separator with a coalescent filter was installed in the New Service Complex in Zrenjanin, and the wastewater treatment plant at Novo Miloševo waste mud landfill is subject to trial operation. To further modernise the Pančevo Oil Refinery plants and work processes, in late 2017 we started constructing a ‘Bottom of the Barrel’ plant to process refinery residue through a delayed coking process. In addition to an increase in the depth of oil processing and production of high-calorie fuel – the coke, which is now an import product, the construction of this plant will significantly reduce the emissions of SO2, NOx and particulate matters, while also meeting the requirements of the Directive 1999/32/EC relating to a reduction in the Sulphur content of certain liquid fuels. Once the plant is completed, the final effect will be a reduction in SO2 emissions in the air in the entire Republic of Serbia as a result of a lower share of fuels high in sulphur content in the market. In 2017, the following study was completed: Analysis of wastewater treatment plants/equipment at NIS j.s.c. Novi Sad and consideration of the necessity of constructing new and reconstructing/optimizing the existing ones in order to meet regulatory requirements in the field of water and environment protection (Institute ‘Jaroslav Černi’, Belgrade). The Study encompasses all organisational units and prioritises future activities to improve the current situation and comply not only with domestic regulations, amended in 2016, but also with the European legislation in this field. Preparation of the Study of Geoelectrical Tests at the location of the Petroleum Product Warehouse Novi Sad is underway as per the Project of Analysing the Need for Rehabilitation and Remediation of Groundwater and Soil at the Petroleum Product Warehouse Novi Sad, prepared by NTC NIS Naftagas d.o.o. Novi Sad and the Faculty of Science in Novi Sad, Department of Chemistry, Biochemistry and Environmental Protection. The aim of the Study is to examine the state of groundwater contaminated in the destruction of the Refinery in Novi Sad during the 1999 bombing. Significant funds have been invested so far to remediate historical pollution and bring the contaminated areas back to their original use. This year, we remediated 14 primary mud pits and one absorptive pool, total area 8,500 m2. So far, 185 primaryт mud pits have been remediated with a total area of 127,865 m2. As part of HSE process automation, the ‘Waste Log Application’ was developed to help handling the documents relevant to the waste management process, which users can access from any NIS location. The application allows data search by 25 criteria, creating different user-required and statutory reports. The model of framework contracts continues to be implemented at the Company and Subsidiary level when contracting waste management services (covering all types of generated waste except for oily waste). This year, the contract with the contractors was concluded for a period of three years (until 2020) with the possibility of concluding annexes for new contractors and new types of waste. Next year, it is expected that this model (framework contracts) will be used to contract oily waste management services and laboratory analysis services. Constant improvement of the employee and operator competencies continued through training and workshops on chemicals management, waste management, measurements of pollutant emissions in the air, water and soil. Four workshops were held on chemicals management, one workshop on energy efficiency and climate change and one on waste management, one workshop on emissions measurement with accredited laboratories, and a forum of contractors – waste operators. As the year 2017 was declared the Year of Ecology, it featured corresponding activities: Nature Conservation Day – 11 April, marked by organizing an exhibition of photographs of the nature of Vojvodina and screening the film ‘The Danube, River of Life’ at the Business Centre in Novi Sad, as well as handing out of leaflets on protected areas in Vojvodina in petrol stations as part of the HSE campaign ‘Take Care of Nature’. Arranging a ‘Working Day for Nature’, on the occasion of 5 June, World Environment Day, our volunteers cleaned Rakovac, Dobočaš and Điros streams in Fruška Gora. On 20 October, we gave our contribution to preserving the largest open space of steppe habitats Korn in the Special Nature Reserve Deliblato Sands. In 2017, about RSD 334.4 million was allocated for environmental protection and water charges and fees.
