Environmental Impact Assessment Study for 400 kV OHL SS Stip – Macedonian-Serbian Border• ααη, αηα, θ, θα, ω∋ – Volcanic rocks and inter-layers sediments.. They characterisewith developed fracture porosity shallow under the surface, and quantity of (Qi = 0.05 –0.5 l/s). Most of them flow temporarily. The maintenance of theese layers comes fromatmosphere falls.• τβ – Kyanite and trachybasalt . They have the same characteristics as the previouslydescribed rock masses.• Sca - Metamorphic sandstones. They have the same characteristics as the previouslydescribed rock masses. These rock masses supply and drain the water through lateralcontact with porous marble masses.3. Predominantly Porous Rocks (sediments)This group of rock masses (sediments) has the following characteristics:• Low level of porosity and water production (T < 15m 2 /day).• The presence of springs with low level of production (Qi < 0,5 l/s) in non coherent rockmasses. Most of them are of temporary nature.• The presence of shallow dug wells for the cattle and irrigation, which are generallyexploited by occasional manual drawing water from the well.• Developed cracks and porosity, shallow under the surface and local limited spreading.Within this group, there are:• D, b – deluvial and organogenic marsh sediments.•4 E 3 [ 3 E 3 ] – Upper Eocene flysch sediments• F; Sse – fylite and sericite shales within the Paleozoic complex.Registered Hydrogeological Appearances and Objects Along the RouteAlong the route of the transmission line, the following hydrogeological appearances andobjects have been registered:• Temporary marsh areas, next to RP1 and after RP2• Subterranean channel (pipeline) for irrigation, between Rp3 and RP4• Subterranean channel (pipeline), after RP4• Non-captured temporary spring in the streamstream “Solen Dol”, between RP6 andRP7• Temporary marsh aras near Rivers Mechkuevska and Ranchenska, before RP7• Non-captured temporary spring at River Ranchevska, before RP7• Captured dry spring, located on the right side of the road Village Nemanjica – VillageRanchenci, between RP7 and RP8.• Group of dug wells (depth = 3.5 – 5.0 metres), next to and in the Village D. Gjugjance,between RP9 and RP10.• Non-captured spring (Q < 0.1 l/s) in the form of diffuse flow right next to the group ofactive holes, on the west side of the hill "Red Forest", between RP9 and RP10• Temporary marshes near “Boshkov i Drenov Dol", between RP9 and RP10• Drilled well (for irrigation) (Q – unknown), near the stream “Pavlev Doll”, before RP1158
