In accordance with the annual plan and work program of the Oil Transmission System Control Unit, the staff performed technical inspection of the oil pipeline valves at Chiflik and Gradmanci.
They also visited the locality Rogce, near the village of Deren, where construction works for landslide protection were carried out in the previous period. It is visually ascertained that the built stone embankment with protective net does not allow erosion of the land under the pipeline route and drains the leaking ground and ground water.
