ened surfaces were broken up and loose ash was brought to the surface). The area which was subsequently vegetated is now losing its vegetation again in some areas, partly due to a lack of water and partly due to erosion since no drainage trenches were provided. Currently approx. 300,000 metric tons of dry flue ash per year are transported via conveyor belt to the southern area of ash tip A. In addition to the fine-grained tip surfaces which are vulnerable to wind erosion, the dropping of the ash from the belt, in particular from a great height, represents a further relevant source of diffuse dust. For further dispersion calculations in respect of tip wind erosion it is assumed that in each case 1/3 of the surfaces of the tips is subject to dust erosion by the effects of the wind.

The Future Situation
In the future the Kosovo A blocks will no longer be operated. The ash tips shall be redeveloped to the extent that they no longer generate dust emissions. The conveyor belt transport and dumping of dry ash which is also of relevance to the emission levels will also be discontinued. As a replacement for Kosovo A a new “Kosovo C” lignite power station with 4 blocks shall be constructed using state-of-the-art technology. The flue gases from the new power station shall, as is normal nowadays, be discharged via cooling towers. The related emission and source data are listed in Section 4. Three potential locations are currently under discussion. Two of the possible locations are in the vicinity of the existing Kosovo A and Kosovo B sites; the third is near the town of Bivoljak. The redevelopment of the ash tips is planned to take until roughly 2012. The shutdown of Kosovo A will take place at the earliest in 2014 following construction and commissioning of Kosovo C. Kosovo C will probably be built and commissioned in several stages. For the dispersion calculations for the future situation it is assumed that all ash tips have been redeveloped, that Kosovo B is still in operation and that Kosovo C has been fully commissioned with four blocks.
