ENVIRONMENT

The waste that will be treated at the hazardous waste treatment unit and will be available at the landfill after meeting the acceptance criteria, will come exclusively from the operation of the company's crude oil refinery. Before disposal in the landfill cells, the hazardous waste will be processed in the hazardous waste treatment unit. The waste in question is classified as "Sludge from physico-chemical treatment containing hazardous substances" and will come exclusively from the operation of the company's crude oil refinery. The waste treatment method (partial stabilization) concerns its treatment with a suitable material (natural zeolite), which, through the sorption process, binds the pollutants in its mesh resulting in their immobilization. Waste after treatment is classified as "Waste marked with an asterisk as hazardous and partially stabilized". A condition for the disposal of waste in the LANDFILL is the satisfaction of the acceptance criteria defined in section 2.4 of Decision 2003/33/EC, as well as the assessment of its hazardous properties, as defined in the Commission's Communication on the technical guidance for the waste classification (2018/C124/01). Subsequently, the waste processed in the treatment unit that meets the criteria for disposal in a landfill will be disposed of in specially designed areas within the facility. Three cells will be constructed for the sanitary landfill of hazardous waste (with an area of 1350 m3 for cell (A), 3621 m3 for cell (B) and 4950 m3 for cell (C). Their useful volume will be 8202 m3, 12685 m3 and 26730 m3 respectively). In order to ensure the safe handling and transport of the waste to the treatment unit and after treatment in the landfill cells, these activities will be performed by specialized personnel. The leachates that will result will end up in appropriately configured leachate reception tanks (temporary storage). For this reason, three leachate reception tanks (one for each cell) with a useful volume of 56 m3 for cell (A), 137.5 m3 for cell (B) and 187.58 m3 for cell (C) will be constructed and will have anti-corrosion protection. The leachates from the leachate reception tanks will be removed exclusively by tanker vehicles through licensed companies for their management and their recycling in the cells will not be allowed.
