The processes in the field of hazardous waste management and waste water management in the mining industry are very demanding and in the operationalization of the real complex. Oni overall are part of the eco-problems that can have thresholds extremely high risk of environmental affected by mining operations. The overall situation in this area of the Republic of Serbia is burdened by various problems that can be characterized according to different strategic approaches by different influences, levels of government, infrastructure, logistics, capacity of the economy, the availability of material and financial resource potential to eco awareness and eco-culture of almost all component ecosystems with special emphasis on economic entities for activities in mining. When it comes to facilities for the treatment of hazardous waste and waste water in the Republic of Serbia, who are normally the overall strategy on the management of hazardous waste defined as jobs in the first degree of priority, they are in the present context does not take place as planned and that we are faced with problems of it takes a real lot of time in generating quality solutions. U primarily it is indisputable that there is a certain degree of distrust in local communities about the degree of eco safety and potential risks that the planned construction of facilities can bring the spatial locality where they were located or on closer and further environment. There is a total balance of norms and regulations in the context of managing these wastes in the international and national levels, as well as the compliance of national legislation with EU directives, the situation in the region in the field of treatment of hazardous waste and waste water management, programming choices and more. Cited fit points to the need to review the entire situation to redesign existing general strategy of the Republic of Serbia in this area. The paper presents the parameters of the current state of the subject area with the incorporation of some of the possible potential opportunities for overall improvement of the eco status of the environment and the potential risks that need to be minimized and lead to acceptable thresholds above all the general security in the handling of the aforementioned waste in production mining practice. Certainly it necessary to consider the issue of eco awareness and eco-culture with the aim of eliminating mistrust of the general public, to minimize the fear of potential negative effects, but also reduce the opportunities for various abuses that are here really realistic and possible.

Route determination for hazardous material (Hazmat for short) transportation is a main concern in Hazmat management in which transport risk and cost are considered as the main attributes. The pre-defined priorities for risk and cost cause different mathematical models developed to determine the best routes which are not necessarily the shortest paths. In this paper, a tolerated risk usage is utilized to develop mathematical model for selecting the best route for carrying hazardous materials according to risk and path distance. Mathematical model has been developed using preemptive goal programming approach in which transport risk is considered more important than distance at the first step for developing model and route distance is minimized subject to pre-defined risk tolerance at the second stage. Experimental data including eighty-nine nodes and onehundred and one links in a real network has been selected for numerical analysis and results have been discussed. Results revealed that there are some alternative routes when risk tolerance is getting to be increased or long distance paths used for hazardous materials transportation. In addition, using tolerated risk can satisfy both national/local authorities in hazmat management and transport companies as well. [ABSTRACT FROM AUTHOR]
