- 6 - Waste disposal:66.740 ha. Mineral storage:32.240 ha. Infrastructure :12.660 ha. Roads:20.140 ha. Green Belt:69.730 ha. Town ship Area:123.320 ha. Storage of Top Soil:10 ha. Area remains untouched:1021.569 ha. Total:1437.719 ha. (d) Agriculture In the intermountain valleys and other areas, the crop land exists as small patches. The mining operation does not affect any agricultural land inside or outside the lease hold area. (e) Forest (flora & fauna) The forest area covered over 1167.313 ha. The area consists of thin vegetation covered with different species of flora. Fauna like Langur, Jackal, Wolf , Jungle cat, Bat, Jungle owl Squirrels are found in the area. The impact of nice due to mining operation and blasting on wild life is inevitable. (f) Vegetation The overall impact on vegetation is limited to the temporary deterioration of land due to mining and allied activities for which suitable reclamation scheme has been made besides compensatory afforestation for forest land. The bio-diversity closer to and away from mining areas does not show any significant deviations. (g) Public building, places and monuments (protected monument and historical monument), places of worship and places of tourist interest. There are no protracted monuments and historical monuments in side the core and buffer zone. ii) Water Environment (a) Surface water The natural drainage system is distinct due to hilly topography in most part of the study circle. Baitarani River flowing at a distance of about 3.5 km on eastern side of the Joda West lease forms the major drainage system of the area. Kundra nala originating from a liter distance beyond the Southern hilly region flows adjacent to the Western and Northern boundary of Joda West lease. Major part of the area has dendritic drainage pattern. (b) Ground water Core zone is mainly hilly area. The area is under hard rock formations. The rock do not have primary porosity; only structural weaknesses like joints, fractures, folds, faults and weathering processes provide secondary porosity for storing and transmitting water. The ground water occurs under unconfined to semi confined conditions. The area received recharges mainly from participation and surface sources. (c) Quality of water Samples were drawn at upstream & downstream of Kundra, Nallah. The average result is enclosed as Annexure-III. iii) Air Environment (a) Noise The noise level is being monitored and no significant impact has been observed as of now. Existing control measures to preserve environment caused by noise pollution are; a) Mufflers and silencers are used in mining and earth moving equipments, b) Noise level from dumpers and other vehicles are kept low by avoiding travel in excess gradient. c) Maintenance schedules are adhered strictly. d) Operating personnel working near the machine are provided with ear plugs. The details of noise monitoring is enclosed as Annexure-IV (b) Air The monitoring result show that, the mining activities has not created a significant impact on
- 7 - ambient air quality primarily due to medium scale operation and secondarily due to dense vegetation around the mining area. The month wise analysis of ambient air quality from Apr’09 to Sept’09 is shown in Annexure-V. (c) Climatic condition The core area lies in tropical region having an extreme climate. The winter temperatures of the study area indicate that it is the subtropical region. Summer is typically from March to mid June when temperature ranges from a maximum of 44ºC during daytime to a minimum of 23ºC at night. Winter is from December to February when the maximum temperature during day goes up to 29ºC and minimum temperature at night becomes as low as 4ºC. iv) Socio-economic environment (a) Social and demographic profile The area has primarily forest and fallow land. Most of the smaller villages and hamlets consist of a single tribe or caste population. The local tribes are Munda, Savara, Santhal, Ho, Oroan, Kahala, Dhiba, Naik, Patra, Sohri, Manji, Gopa, Korwa, Mahakut, and Doon. A number of scheduled castes are also local habitants. They are Bajikar, Bedia, Beldan, Bhoi, Chema, Dandasi, Dhewar, Kandra, Kori, Laheri, Madari, Mala, Mahan, Musahar, Panika, Pasi Tusi etc. The people are mainly forest dwellers with agriculture as their main activity. Other than this, a large number of people are employed as labourers in the various mining companies. (b) Recommending health and safety The climate and vegetation along with the topography have made the area fairly inhospitable. Dense tropical forest, abundant stagnant water and humidity are conducive to giving rise to a number of diseases. However , Tata Steel Rural Development society put the continuous effort towards awareness of people and rendering the medical support inside the core and buffer zone. (c) Human settlement Population in the study area is little less than 1 lakh. Excluding the urban population the average settlement size is 501.69% of the settlements have a population less than 501 while almost 92% of the settlements have less than 1000 inhabitants. The terrain and ecology do not permit larger settlements. (d) Recreational facility Free housing, electricity , water, Tata Sky facility conveyance allowance , School Bus to Joda, Medical facilities, LTC, bonus and other hosts of welfare facilities provided to the workers and other employees. 8. Sensitive technical items on conservation of mineral, scientific mining and protection of environment Specific issues that are required to be kept in focus for examination & monitoring should be stated here. Sensitive technical items on conservation of mineral, scientific mining and protection of environment, specific issues that are required to be kept in focus for examination and ; monitoring should be stated here. While doing the scientific mining for the judicious exploitation of mineral deposit approx. 10% of the ore production is assessed to be sub-grade mineral comprising of Manganese fines, which is separately stacked from overburden waste. The average grade of the sub grade mineral is found in the range of 10-25% Mn. Ore which is recommended by IBM. In addition to this due course of mining in the mineral fines (rejects) which are generated approx. 10% of the ore production & stored separately as sub grade mineral. Efforts are being made for the sale of Mineral Fines (rejects) in the local market as well as Exports. Boundary pillars of the lease area are found fixed on the earmarked place having 4 feet height with bearings & directions distinctly marked on them. Regular monitoring is being done for following aspects to comply the specific conditions imposed in Environmental Clearance obtained from MoEF. a) Ground water level in the wells,
