Environmental Impact Assessment Study for 400 kV OHL SS Stip – Macedonian-Serbian Border5.5 Mitigation Measures for Reducing the Impact on the Quality of Surface WatersConstruction phaseEventual construction zones will be established at the appropriate distance from near surfacewaters.The general measures for reduction of the potential impacts of discharges in the surfacewaters, in the construction phase include procedures of good construction practice:• If necessary, implementation of control measures for erosion and sedimentationthrough the establishment of temporary drainage, for diverting of potentiallydangerous surface water, originating from construction sites.• Minimizing the stockpiling out of the construction site and avoiding areas close towatercourses• Locating stockpiles outside the drainage lines, surface water and road surfaces.• Removing the stockpiles asap• Provision of equipment for evacuation of leakages.• Setting up mobile toilets at a distance greater than 100 meters from the drainagelines.• Contracting authorized service company for management and disposal of wastewater from the mobile toilets.Operational phaseBearing in mind the sources of potential pollution, the measures for reduction of the potentialimpacts of emissions in surface waters in the operational phase include, above all, activitiesfor the maintenance of access roads.During the maintenance and control activities, the personnel will be responsible to complywith the requirements for municipal order, in respect of dumping of waste near surfacewaters, and in relation to situations of leakage of fuel or oil from vehicles.132
