MINING AND INDUSTRIALISATION UPDATE, ORISSA - Vasundhara

(iv)(v)(vi)(vii)The top soil shall temporarily be stored at earmarked site only and shall not bekept unutilized for a period more than 3years. The topsoil should be used for landreclamation and plantation.The project proponent shall develop fodder plots in the non-mineralised area inlieu of use of grazing land...3/-Over burden (OB) generated during the mining operation shall be stacked atearmarked dump site(s) only and should not be kept active for long period oftime. Proper terracing of OB dump(s) shall be carried out so that the overall slopeof dump(s) shall not exceed 28 0 . The OB dump(s) should be scientificallyvegetated with suitable native species to prevent erosion and surface run off. Incritical areas, use of geo textiles shall be undertaken for stabilization of thedump(s). Monitoring and management of rehabilitated areas should continue untilthe vegetation becomes self-sustaining. Compliance status should be submitted tothe Ministry of Environment and Forests and its Regional Office located atBhubaneswar on six monthly basis.Catch drains and siltation ponds of appropriate size shall be constructed for theworking pit, OB dump(s) and mineral dump(s)s to arrest flow of silt and sedimentdirectly into the Vansadhara River, Barha Nallah and other water bodies. Thewater so collected should be utilized for watering the mine area, roads, green beltdevelopment etc. The drains should be regularly desilted, particularly aftermonsoon, and maintained properly.Garland drains, settling tanks and check dams of appropriate size, gradientand length shall be constructed both around the mine pit and over burden dumpsto prevent run off of water and flow of sediments directly into the VansadharaRiver, Barha Nallah and other water bodies and sump capacity should be designedkeeping 50% safety margin over and above peak sudden rainfall (based on 50years data) and maximum discharge in the area adjoining the mine site. Sumpcapacity should also provide adequate retention period to allow proper settling ofsilt material. Sedimentation pits should be constructed at the corners of thegarland drains and desilted at regular intervals.(viii) Dimension of the retaining wall at the toe of OB dump(s) and OB benches withinthe mine to check run-off and siltation should be based on the rain fall data.(ix)(x)Plantation shall be raised in an area of 2.05ha including a 7.5m wide green belt inthe safety zone around the mining lease, OB dump(s), roads etc. by planting thenative species in consultation with the local DFO/Agriculture Department. Thedensity of the trees should be around 2500 trees per ha.Regular water sprinkling should be carried out in critical areas prone to airpollution and having high levels of SPM and RPM such as haul road, loading andunloading point and transfer points. It should be ensured that the Ambient AirQuality parameters conform to the norms prescribed by the Central Pollution54
