1.0 Executive Summary The Mining area is situated near Village Kalta, Tehsil Bonai, District Sundergarh, State Odisha. The lease area comprises of 25.981 hectares, which is a forest land. The Mine Lease number being 139 and it is operated by Steel Authority of India Ltd, under the name “Kalta Iron Mines”. The lease area measuring 25.981 ha was granted for extraction of iron ore by the Department of Steel and Mines, Government of Odisha and the same was executed on 17.01.1975 for a period of 20 years ie., up to 16.01.1995. Originally, the lease was granted for an area measuring 38.182 Ha and the same was spread over in two blocks namely Block „A‟ of 22.9982 Ha and Block „B‟ of 15.1838 Ha. However, during execution of the deed a portion of the allotted lease area measuring 12.201 Ha, located in the northern side of the lease area and forming a part of district Keonjhar was deducted from the total lease area. Thus the executed area located in two blocks was 10.7972 Ha in Block A and 15.1838 ha in Block B, aggregating to a total of 25.981 ha. The mining plan was approved by the Indian Bureau of Mines (IBM) vide letter No. CAL/SG/FC/MP-400 dated 28.03.1996 and the same was valid till 2014-15. Since the above mining plan did not contain any progressive mine closure plan the same was prepared and incorporated. The modified mining plan was approved by IBM vide their letter no. MPM/OTFM/17-ORI/BHU/2012-13 dated 21.06.2013. Application for renewal of the same has been done on 16.2.1994 considering the Mines and Minerals (Development & Regulation) Amendment Act, 2015 of Govt. of India, the mining lease would be extended up to 16.01.2025. To this effect Dept of Steel and Mines, Govt of Odisha has issued a letter to the lessee to execute the supplementary deed for a lease period of 50 years. Therefore, the present modification to the mining plan is submitted now for five years from the proposed periods of the approved mining plan, i.e. from 2015 -16 to 2019 -20 considering the period of extension of the mining lease till 16.01.2025. As the first year of the ensuing plan period (2015 -16) has already been elapsed, detail planning has been proposed for the period from 2016- 17 to 2019-20 in this document. The aforesaid mine lease area measuring 25.981 ha is for extraction of Iron Ore. The annual production is targeted at 49701 Tonnes per annum. Open cast semi mechanized mining method is proposed to be implemented. Sizing, sorting and blending will be carried out manually by raising & crushing. The cost of the project is Rs 10.08 Crore. A copy of the Approved Mine plan is attached as Additional Documents).

Water will be used for Drinking, Domestic uses, Plantation, and Dust suppression. Sources of water For meeting water requirements at Kalta Mining Complex, the management has developed a 1,500 m3 impoundment by constructing a weir in the Najkura Nala (which flows near the mining site), from where about 250 KL of water is pumped every day. However, as this source of water is depleting, two alternatives are under active consideration of the management. These areas are (1) Tapping ground water through boreholes and submersible pumps, and/or (ii) Drawing water from the Samaj Nala which is also a perennial nala. In addition, across the road from the Kalta Mine

Office, there is an old Prospecting Camp, where 29 meter deep artesian well is located. The artesian well provides a continuous flow of water under artesian pressure through a 5 cm dia. Pipe. This water is sufficient enough to meet the requirement of the residents as well as people living in nearby bastis.

Apart from direct employment in the proposed mining project there will be indirect employment opportunities in the informal sector to the tune of about 100 persons from the nearby villages. Also, the mine owner will conduct medical camps at regular intervals in the nearby villages and will also develop much needed infrastructure like construction of toilets, provide furniture and RO water purifying system in the nearby schools. 2. INTRODUCTION OF THE PROJECT/BACKGROUND INFORMATION 2.1 Identification of Project and Project Proponent 2.1.1 Identification of Project The Mining area is situated near Village Kalta, Tehsil Bonai, District Sundergarh, State Odisha, over an area comprising of 25.981 hectares which consists of forest land. ML-139 lease is operated under Kalta Iron Mine Steel Authority of India Limited, Raw Materials Division. Mining lease was granted for mining of iron ore which was executed on 17.01.1975 for a period of 20 years over 25.981 ha. The original granted area was 38.182 ha spread over two blocks namely Block A of 22.9982 ha and Block B of 15.1838 ha totaling 38.182 ha. However, during execution a portion of 12.201 ha located at the northern side of the leasehold and coming within the district of Keonjhar was deducted from the total area keeping the area of the lease to 25.981 ha. The executed area is located in two blocks namely Block A of 10.7972 Ha and Block B of 15.1838 ha aggregating to 25.981 ha. The mining plan has been approved by IBM vide letter No. CAL/SG/FC/MP-400 dated

28.03.1996 and was valid up to 2014-15. In the earlier approved mining plan no progressive mine closure plan was prepared. So the approved mining plan was modified to include Progressive mine closure plan. The above said modified mining plan was approved by IBM, Bhubaneswar vide letter no. MPM/OTFM/17-ORI/BHU/2012-13 Dt. 21.06.2013. The aforesaid mine lease area measuring 25.981 ha is for extraction of Iron Ore. The annual production is targeted at 49701 Tonnes per annum. Open cast semi mechanized mining method is proposed. Sizing, sorting and blending will be carried out manually by raising & crushing. The cost of the project is Rs 10.08 Crore. This mining project falls under Category “A” Project or activity 1(a) as per EIA Notifications 2006 and its subsequent amendments. 2.1.2 Identification of Project Proponent The mining project is proposed by M/s Steel Authority of India (SAIL) having its Registered Office at Ispat Bhavan, Lodi Road, New Delhi-110003 and its Raw Materials Division is located at Industry House, 10, Camac Street, Kolkata-700017. 2.2 Brief Information about the Project: The proposed Kalta Iron Ore Mines (ML-139) is situated in near Village Kalta, Tehsil Bonai, District Sundergarh, Odisha. The method of mining will be open cast semi mechanized mining. The expected life of the mine is 60 years. The minerals to be extracted from the lease area will be Iron Ore. The annual production is proposed to be around 49701 Tonnes. Open cast (OTFM) fully mechanized mining is proposed to be adopted for extraction of minerals. Sizing, sorting and blending will be carried out manually by raising & crushing. The estimated cost of the project is Rs. 10.08 Crores. 2.3 Need for the Project and Its Importance to the Country or Region Metallic Iron is extracted from Iron ore. The ore is usually rich in Iron Oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The Iron itself is usually found in the form of Magnetite (Fe3O4, 72.4% Fe), Hematite (Fe2O3, 69.9% Fe), Goethite (FeO(OH), 62.9% Fe), Limonite (FeO(OH)·n(H2O), 55% Fe) or Siderite (FeCO3, 48.2% Fe). Metallic Iron is virtually unknown on the surface of the Earth except as Iron-Nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Although Iron is the fourth most abundant element in the Earth's crust, comprising about 5% of the vast majority is bound in silicate or more rarely carbonate minerals. The thermodynamic barriers to separate pure Iron from these minerals are formidable and energy intensive. Therefore all sources of Iron used by human being are comparatively rare. Iron Oxide minerals, primarily Hematite, Iron-ore mining methods vary by the type of ore being mined. Depending upon mineralogy and geology of the ore deposits there are four main types of Iron-ore deposits currently being found. These are Magnetite, Titano-Magnetite, massive Hematite and Pisolitic Ironstone deposits.

The production of Iron is due to use of Iron ore. Most of the Iron produced is used to make steel. Steel is used in many industries such as automobiles, locomotives, ships, beams, buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles etc. The entire production from the proposed Mine Lease area (number 139) will be supplied to the Rourkela Steel Plant (RSP), which is an integrated steel plant of SAIL. 2.4 Demands-Supply Gap There is a huge demand for Iron Ore in the country for feeding the Steel plants. The entire production from the proposed mine will be used by the Rourkela Steel Plant (RSP). Thus the mine lease area referred above will become a captive mine of the Steel Authority of India, when in operation. 2.5 Imports vs. Indigenous Production The needs of the Rourkela Steel Plant (RSP) will be met through locally extracted Iron ore from the above mine. There will be no import due to high cost. 2.6 Export Possibility There is no export possibility as the entire output will be used by the Rourkela Steel Plant (RSP). 2.7 Domestic/Export Markets The Project Proponent will use the extracted mineral for captive use in their Integrated Steel Plant at Rourkela. 2.8 Employment Generation The total manpower requirement for the above mining project has been estimated at 86 persons. Preference for employment will be given to local jobseekers. There will also be indirect employment opportunities for the local people in the informal sector, which will be around 100 persons. 3. PROJECT DESCRIPTION 3.1 Type of Project Including Interlinked and Interdependent Projects, If Any. It is a mining project for extraction of Iron ores to be supplied to Rourkela Steel Plant of SAIL. This is an independent mining project and no interlinked projects are involved. As per EIA Notifications dated 14th September, 2006 and subsequent amendments it is a Category “A” Project or activity 1(a). 3.2 Location The proposed mine lease area of M/s Steel Authority of India (SAIL) is located near Village Kalta, Tehsil Bonai, District Sundergarh, Odisha. The lease area can be identified through Topo Sheet No. 73 G/1 and 73 F/4. The geographical coordinates are provided below: Block Name Latitude Longitude Block „A‟ 220 00‟ 8.23” to 220 00‟ 34.70” 850 13‟ 54.69” to 850 14‟ 10.50” Block „B‟ 210 59‟ 46.87” to 220 00‟ 5.10” 850 13‟ 37.30” to 850 13‟ 56.30”

One can reach the project site through NH-215, which is about 5.5 Km in SE direction of the lease area. The nearest Railway Station is Barbil Railway Station, which is about 47 Km in NE direction. The „Biju Patnaik International Airport, Bhubneshwar‟ is about 325 Km in SE direction from the project site. The Google image of the lease area, NH-215, and village Kalta and other nearby villages is furnished below in Figure 1.

Fig 1: Location Map of Proposed Project Site Showing on Google Image 3.3 Details of Alternate Sites As mining is site specific no alternative site is proposed. 3.4.1 Size or magnitude of operation The mining lease area measures 25.981 ha, which is a forest land. The annual production has been estimated at 49701 Tonne. The average number of days for which the mine will be operational is 300. 3.5 Physiography The lease area is an undulating hilly terrain. The highest altitude is 860 m, in northern part in Block-A and the lowest is 760 m in the western part of the lease area in Block-B. The maximum gradient of the area is 1 in 2 and minimum is 1 in 13.

ML-139 is located north of Majurnachan Pahar, immediately to the north of Kalta end of ML-130. The NE – trending elongated narrow hill range is a prominent drainage barrier between the western rugged terrain and the eastern undulating & plain country. The gullies along the scarp slopes in the 6

western part give rise to numerous nalahs which join to form streams. The latter discharge into the Kurhadi nadi, which originates in the south-eastern side of the Dandrahar Pahar and, after girdling it takes a north-westerly course. The Barsua Township of SAIL-RMD is located in a valley of this river. 3.5.1 Local geology: The sequence of rocks in the Barsua – Taldih – Kalta belt is as follows:

 Upper Shale

 Banded Haematite Jasper (B.H.J)

 Massive Iron Ore.

 Lower Shale

The Upper Shale forms the central shale and clay band in the whole of Barsua Block and in a part of Taldih „A‟ Block, after which it gradually swings to the east and passes along the eastern margin of the ore-body in the Kalta block. Upper shales are not present in ML-139. Banded Haematite Jasper, a hard and resistant rock, constitutes the dominant litho-type of the hill range. In the peaks areas, it is generally capped by iron-ore, while in the lower areas, laterite blanketing is common. BHJ exposures are generally seen at the escarpment faces of the hill. Massive Iron Ore in ML-139 occurs as capping of the two hills, separated by BHJ in the lower elevation in the between. The two occurrences identified as Blocks „A‟ and „B‟. Lower shales are associated with phyllites and volcanic tuffs in the Barsua area. In ML-139, lower shales (without tuffs) are generally present in the lower slopes on the western side. The general strike of the formation in the area is NNE-SSW, with a dip of 800 on the western flank and 450 on the eastern slopes. The general direction of the dip is westerly. Several structural features in the area exerted their influence on the form and extension of the ore bodies. Local folds and slips are common. Two sets of joints, one parallel and the other transverse of the hill range, are prominently marked. Description of the ore body: The iron ore bodies in the area generally occur in the higher area of the hill range, as capping. The mode of occurrence of iron-ore in the area supports the general conception of ore-formation by secondary processes of leaching, replacement and concentration of iron oxides and hydroxides by the action of circulating meteoric water under structural and geochemical controls. Lateritisation which adversely affected the ore horizons at places also resulted from the same processes. In ML-139, iron ore is found in two areas separated by BHJ exposures. The southern ore zone has been identified as Block „B‟ and the northern one as Block „A‟. In both blocks, iron ore is found as capping on higher ground, while the break in the continuity of the ore horizons has been caused by exposures of BHJ on comparatively lower

ground in between. Thus, the disposition of the two ore bodies in ML-139 is a geo-morphological expression rather than any structural discontinuity. 3.5.2 Regional geology – The Iron Ore bearing and associated suites of rocks in the area are constituted of the precambrain meta-sedimentary sequence known as the Iron Ore series, which covers the southern Singhbhum and adjoining Keonjhar & Sundargarh districts of Odisha. It has now been generally accepted that the Iron Ore Series was deposited on the denuded edges of older metamorphic suites. The ore bodies are associated with banded hematite-quartzite of the iron-ore series. The original rocks consisted of alternating ribbons of quartz jasper and haematite, from which silica was leached out and iron-ore bodies formed by the secondary processes of replacement & concentration of iron oxides & hydroxides. 3.6 Project description with process details

3.6.1 Method of Mining It is planned to adopt the “OTFM A” open-cast semi mechanized mining method in this ensuing plan period. The height of the individual benches shall be made and maintained at 6m and width of minimum 10 m. 100 mm diameter holes will be drilled with the help of wagon drills to a depth of 6.6 m with 10% sub-grade drilling at a spacing and burden of 3 m x 2.5 m. The overall bench slope will be maintained at 450. For primary blasting 83 mm, 2.78 kg slurry/ emulsion explosive cartridges will be used where as secondary blasting will be done by plaster shooting. Blasting will be generally carried out once in a week. The blasted boulders will be manually sized and sorted to around 300 mm average size. The sorted boulders will be thereafter stacked for measurement and loaded into trucks of 10t capacity. Hence, “OTFM” opencast method of mining is proposed to be continued. The mine working is proposed to be restricted within the influence zone of section lines. Mine approach roads having suitable gradient i.e. 1 in 16 to 1 in 20 are to be developed for smooth and safe transportation of ores and waste material. Steps are to be provided within benches for easy movement of workers. It is proposed to operate the mines on single shift basis. Keeping in view of holidays, stoppage of work due to rain and other un-foreseen circumstances 300 days per year have been considered for effective mining operation. The blasted boulders will be manually sized and sorted to around 300 mm average size. The sorted boulders will be thereafter stacked for measurement and loaded into trucks of 10t capacity. The oversized boulders will be subjected to manual crushing and sizing. The lumps and fines will be segregated, which will in turn be transported to the Roxy railway siding at a distance of around 22 km by 20t trucks. Overburden/ Inter-burden will be loaded through 0.9-1.0 cum excavator into 10 t/ 20t dumpers for its disposal in the proposed dump. Rock

breakers will be used in case of large size boulders. The O/B to be generated during the course of mining operation shall be stacked separately at the dumping site. As ML 139 and ML 130 of SAIL share common boundary and the boundary is mineralized, the lessee wants to mine out the common boundary for which an application has been made to DGMS for their permission. Drilling & Blasting: Drilling and blasting will be required for loosening of the rock mass for ease in excavation. Controlled blasting along with Shock tube initiation system/NONEL system of blasting will be adopted for getting optimum blast result and minimization of flying rocks.

Broad blasting parameters Drill holes will be drilled in single rows as well as in multi row on staggered pattern by wagon drills. However, drilling, blasting parameters are chosen as follows:

Sl. No. Parameters Magnitude 1 Dia. of the hole 100mm Burden 2.5m 2 Drilling pattern Spacing 3.0m 3 Blast hole 6m Depth Sub-grade drilling 0.6m total 6.6m 4 Nature of the hole Vertical 5 Type of main explosive Name SMS 6 Powder factor 6 t/kg Quantity/hole 23.55 kg 7 Requirement of explosive Quantity/single blast 235.5 kg Detonator OD 8 Initiative explosive Fuse NONEL Primary 9 Type of blasting Frequency of blasting

10 Yield/hole 49.5 m3

Blasting induced vibration study is proposed to be carried out immediately after opening of mine and accordingly optimum charge per delay and most suitable drilling and blasting design along with initiation/firing pattern would be deciphered.

Type of explosive to be used Shock tube initiation system/NONEL system of blasting will be adopted for getting optimum blast result and minimization of flying rocks. Storage and transportation of explosives The mine management has a magazine of 7.725 tonnes capacities, which will be common for the adjacent ML 130, 139 & 227 leases. Loading equipment

Loading of waste to tippers will be done by using Porcelain/Payloader of 0.9 m3 bucket capacity. Excavation Specification Bucket capacity = 0.9CuM Production efficiency [machine operating efficiency + job management efficiency] = 90%

Time cycle/pass at 900 swing = 25sec Excavating Parameters Nominal bucket capacity = 0.9CuM Average nominal bucket capacity [C] = 1CuM Bucket fill factor [f] = 0.9 Time cycle/pass at 900 swing [T] = 25sec Swell factor [s] = 0.7 Production efficiency factor [e] = 0.9 Seconds per hour [t] = 3600 Depth of cut factor [d] = 0.95

3.7 Raw Material Required Along With Estimated Quantity, Likely Source, Marketing Area of Final Product/S, Mode of Transport of Raw Material and Finished Product No raw material will be required for production of Iron Ore. 3.8 Resource Optimization/ Recycling and Reuse Only water will be used as resource optimization/recycling at the mine site. 3.9 Availability of Water, Its Source, Energy/Power Requirement and Source 3.9.1 Water Requirement For meeting water requirements at Kalta Complex, the management have created a 1,500 m3 impoundment by constructing a weir in the Najkura Nala (which flows near the property), from where about 250 KL of water is pumped every day. However, as this source of water is depleting, two alternatives are under active consideration: (1) Tapping ground water through boreholes and submersible pumps, and/or (ii) Drawing water from the Samaj Nala which is also a perennial nala.

In addition, across the road from the Kalta Mine Office, there is an old Prospecting Camp. This camp has 29 m deep artesian well which gives a continuous flow of water under artesian pressure through a 5 cm dia. Pipe. This water is sufficient to meet the requirement of the residents as well as those of nearby basti. 3.9.2 Power Electric power supply will be received through a 11 KVA feeder line from the Orissa State Electricity Board Sub-Station at Tensa. It is stepped down to 440 V in two sub-stations. One 500 KVA transformer is located in the Colony sub-station, while one 500 KVA and two 250 KVA transformers, are located at the Mining sub-stations at the hill top. 3.10 Quantity of wastes to be generated (Liquid and solid) and Scheme for their Management/Disposal 3.10.1 Nature of Waste The wastes to be removed from the quarries are mainly composed of laterite, morum, BHJ etc. The lessee has been dumping the waste material generated during previous mining operations in the adjacent lease area of M.L-130. Therefore till date there is no dump found within the lease area of M.L-139. In the ensuing plan period the iron quarry in block-B will be worked out and the volume of waste to be generated from the iron quarry are as follows. Waste to be generated from Iron pit Year Vol. of OB m3 Total Swell vol. of waste m3 2016-17 13,034 20,854 2017-18 2,929 4,686 2018-19 909 1,454 2019-20 16,463 26,341 Total 33,335 53,335

Dumping Site In the lease area it has been proposed to dump the generated waste at the southern part of the lease area of Block-B. Dump site selected for disposal of the waste have been considered after considering the following criteria.  The dumpsite has been located outside the mineralized zone beyond ultimate pit limit.  Topography features have been taken into account, particularly in the context of water drainage. As the lease area is yet to be explored, boreholes have been proposed for complete exploration in the present plan period after commencement of mining operation. Therefore, no area right now can

be declared as barren. However, for planning purpose, area which seems to be barren from geological observations has been selected and planned now for dumping purpose. After commencement of mining operation, exploratory drilling would be undertaken in these areas to prove their barrenness. The earmarked site is to be proved barren by putting boreholes in the year 2016-17. If the area is found to be mineralized then a modification to the approved mining plan will be submitted later. Before start of dumping, retaining wall and garland drains are to be constructed around the proposed dump site. Also, plantation will be undertaken all around the proposed site over 0.40 Ha before start of dumping. Stacking of sub-grade materials: In the ensuing plan period no sub-grade will be generated, hence stacking of sub-grade ore does not arise. Storage of Top-soil: No top soil will be generated in the ensuing plan period as there is no top soil present in the area. Hence storage of top soil does not arise. Maximum height and spread of dumps: In the ensuing plan period a vol. of 53,335 m3 swell waste will be generated. Out of this, 615 m3 swell waste will be utilized for backfilling of the broken up safety zone area around the iron pit in the western and southern side of block-B and a volume of 27,002 m3 waste will be used in infrastructure development. It has been proposed to dump the balance waste of 25,718 m3 generated during the last year 2019-20 over the proposed dump over an area of 9002 m2 or 0.9 ha. 3.10.2 Liquid Effluent Not applicable 4. SITE ANALYSIS 4.1 Connectivity Kalta Iron Ore Mine is situated in near Village Kalta, Tehsil Bonai, District Sundergarh, State Odisha. It is well connected by NH-215 which is about 5.5 Km in SE direction. Nearest Railway Station is Barbil Railway Station which is about 19 Km in NE direction. Biju Patnaik International Airport, Bhubneshwar is about 208.5 Km in SE direction from the project site. 4.2 Landform, Land use and Land ownership Total mining lease area of the project is 25.981 ha is Forest Land. Non-Forest (Ha) Forest (ha) Nil Reserve Forest 25.981

4.3 Topography and Drainage The area under reference is almost an undulating hilly terrain. The highest altitude of 860 m is noted in northern part of the lease area (Block-A) and lowest altitude of 760 m at the western part

of the lease area (Block-B). The maximum gradient of the area is 1 in 2 and minimum is 1 in 13. Drainage pattern- ML-139 is located north of the Majurnachan Pahar, immediately to the north of the Kalta end of ML-130. The NE – trending elongated narrow hill range is a prominent drainage barrier between the western rugged terrain and the eastern undulating & plain country. The gullies along the scarp slopes in the western part give rise to numerous nalahs which join to from streams. The latter discharge into the kurhadi nadi, which originates in the south-eastern side of the Dandrahar Pahar and, after girdling it, takes a north-westerly course. The Barsua Township of SAIL-RMD is located in a valley of this river. The eastern side drainage is controlled by the Samaj (or sominj) nala on the immediate east of the Barsua – Taldih sector till it crosses the range towards west, forming a valley at an altitude of 550 mRL between the Majurnachan pahar and the Karaspani pahar. The samaj Nala, in its down course thereafter, controls the drainage system of the whole western rugged country. In the case of ML-139, a nala originating between Block „A‟ and Block „B” from the western face of the hill, meanders westwards till it meets the Samaj Nala. The karo nadi controls the drainage on the eastern side of the hill range, flowing parallel to it at a distance of about 4.5 km. 4.4 Existing land Use Pattern

4.5 Existing Infrastructure

All services provided at the Kalta Iron Ore Mine (KIM) will be common for ML – 130, 139 & 227 leases. Industrial Services-

Power: Electric power supply is received through 11 KVA feeders from the Orissa State Electricity Board Sub-Station at Tensa. It is stepped down to 440 V in two sub-stations. One 500 KVA transformer is located in the Colony sub-station, while one 500 KVA and two 250 KVA transformers, are located at the Mining sub-stations at the hill top.

Workshop Facilities: The Kalta Mine has a Field Maintenance and Repair Shop for routine jobs. Major repairs are undertaken at neighboring Barsua Mine of the Company.

Water Supply: For meeting water requirements at Kalta Complex, the management have created a 1,500 m3 impoundment by constructing a weir in the Najkura Nala (which flows near the property), from where about 250 kL of water is pumped every day. However, as this source of water is depleting, two alternatives are under active consideration: (1) Tapping ground water through boreholes and submersible pumps, and/or (ii) Drawing water from the Samaj Nala which

is also a perennial nala. In addition, across the road from the Kalta Mine Office, there is an old Prospecting Camp. This camp has 29 m deep artesian well which gives a continuous flow of water under artesian pressure through a 5 cm dia. Pipe. This water is sufficient to meet the requirement of the residents as well as those of nearby basti.

Other Support Facilities: All the Services and facilities required under the Mine Act (and the regulations, Rules and Bye-laws made there under) have been provided at the Kalta Mine. These include a Vocational Training Centre, Rest Shelters, First Aid Stations, a Canteen, an Explosive Magazines, etc. In addition, a site office and public conveniences are also provided.

Township and Municipal Facilities:

A small township spread over 33.9 ha of land outside the mining lease area of ML - 130 has been developed in the Kalta Valley. It has 163 pucca houses and 102 temporary units (making 265 residential units in all), and has been provided with all municipal facilities. The township has its own marketing centre, in addition to the weekly hatia, a co-operative store is also functioning in the colony. Medical facilities are provided through an 18 bed hospital, staffed with three doctors and 23 para-medical & public health personnel. There are two schools in the township, one high School and one Middle School. For recreation, a Community Centre and a Multi-Purpose Centre have been provided besides a cable T.V network. Public utility services in the township include a bank, a post office, the Orissa State Transport buses. For cultural encouragement, the management patronizes the only cultural group in the area, Bhanja Kala Parisad. As has been mentioned earlier, water requirements of the mine and the township are met through (besides a artesian well in the locality) water pumped from a local perennial Najkura Nala. About 250 KL of water per day is pumped daily. Water for human consumption is supplied after treatment at water treatment plant, through an overhead tank and a network of pipes. Treatment of sewage is through septic tanks provided in every building. 4.6 Soil Classification The soil characteristics of the district show wide variation depending upon their occurrence, physical and chemical properties. The soil of the district sundergarh is broadly grouped into1) Ultisols and 2) Alfisols. 1. Alfisols or Red Soil: The Alfisols, in the district, include red sandy soil and red loamy soil. These soil predominantly occupy high and medium land throughout the Sundergarh district. Alfisols are neutral to slightly acidic in nature (pH varies from 5.5 to 6.9). The characteristic features of red soils are (i) light texture, porous and friable structure, (ii) absence of lime kankar and free carbonates and (iii) soluble salts in small quantity usually not exceeding 0.05%. These are usually deficient in nitrogen, phosphate, organic matter and lime. These soils are suitable for cultivation of paddy and other crops.

2. Ultisols: The ultisols comprises mainly of lateritic soils and red and yellow soil. These soils are mildly acidic in nature and deficient in nitrogen, phosphorous and potassium and organic matters. Soils of the district are generally having average to good fertility status. All common types of crops can be grown in the district. The distribution of different soil types in the district depends much on its physiographic and lithological variations. The soil types in Keonjhar district can be broadly divided into two major groups namely Alfisols and Utisols. A) Alfisols: These soils predominantely occur in Harichandanpur, Hatadhi, Ghasipura, Anandpur, Ghatgaon, Telkoi blocks. This group of soil can be sub divided into Sandy soil, red loamy soil, red gravelly soil and older alluvial soil. These soils are light textured usually devoid of lime concretions, nitrogen, phosphate and organic matter. The pH value varies from 6.5 to 7.3. B) Ultisols: These soils predominantly occur in Champua, Patna, Jhumpura, Keojhar and Sharpada blocks. Essentially these are lateritic, red and yellow soil and red gravelly soil. These soils are poor in nitrogen, phosphate, potassium and organic matter. The pH value varies between 4.5 to 6.0. (Source: - Groundwater Information Booklet of Sundergarh and Keonjhar District, Central Ground Water Board South Eastern Region Bhubaneswar, March, May 2013.) 4.7 RAINFALL & CLIMATE The Sundergarh district have sub-tropical climate characterized by hot and dry summer, cold winter rainfall in monsoon. The winter season extends from November till the end of February, which is followed by summer season from March to the middle of June, and rainy season from middle of June to middle of October. During summer months the maximum temperature raises up to 43 oC and May is the hottest month. December is the coldest month of the year when the average daily temperature drops down to 8 oC. Relative humidity is around 60-70% throughout the year. The highest and lowest monthly mean relative humidity is recorded as 97% in Dec and 26% in April. The Keonjhar district is characterized by tropical to sub tropical climate with hot summer, high and well-distributed rainfall during the monsoon and a cold winter. The summer season lasts from March to May; the rainy season starts in June and continues up to September. October and November constitute the autumn season and winter starts in December. May is the hottest month of the year with a maximum temperature is about 46o C and daily minimum temperature 25 oC. December is the coldest month as the mean daily temperature recorded as 12 oC. Relative humidity is generally high from June to December. In summer season humidity varies from 35- 40%. South- west monsoon is the principal source of rainfall in the district. Average annual rainfall is 1535 mm. About 80% of the total rainfall is received during the period from June to September. On an average there are 79 rainy days in a year.

4.8 Social Infrastructure available: All weather motorable roads exist to the lease area. The area is approachable only through the Kalta Iron Ore Mine; in fact Block „B‟ adjoins the main lease ML-130 along its northern boundary. State highway No. 10, connecting Barbil with NH-23 at Rajamunda, passes through the Kalta Mine which lies at a distance of about 110 km from Rourkela (through Rajamunda) and 47 km from Barbil. Rakshi Railway Station, which is the rail head of Kalta Mine, will be used for dispatching ML-139 ore to the Rourkela Steel Plant which is situated approx 120 km from the leasehold via the Kalta Mine. 5 PLANNING BRIEF 5.1 Planning Concept It is planned to adopt the “OTFM A” open-cast mining method in this ensuing plan period. The height of the individual benches shall be made and maintained at 6m and width of minimum 10 m. 100 mm diameter holes will be drilled with the help of wagon drills to a depth of 6.6 m. with 10% sub-grade drilling at a spacing and burden of 3 m x 2.5 m. The overall bench slope will be maintained at 450. For primary blasting 83 mm, 2.78 kg slurry/ emulsion explosive cartridges will be used. Blasting will be generally carried out once in a week. The blasted boulders will be manually sized and sorted to around 300 mm average size. The sorted boulders will be thereafter stacked for measurement and loaded into trucks of 10t capacity. Hence, “OTFM” opencast method of mining is proposed to be continued. The mine working is proposed to be restricted within the influence zone of section lines. The detail lay out of the proposed quarries and sections are shown in plate -V. Mine approach roads having suitable gradient i.e. 1 in 16 to 1 in 20 are to be developed for smooth and safe transportation of ores and waste material. Steps are to be provided within benches for easy movement of workers. It is proposed to operate the mines on single shift basis. Keeping in view of holidays, stoppage of work due to rain and other un-foreseen circumstances 300 days per year have been considered for effective mining operation. The blasted boulders will be manually sized and sorted to around 300 mm average size. The sorted boulders will be thereafter stacked for measurement and loaded into trucks of 10t capacity. The oversized boulders will be subjected to manual crushing and sizing. The lumps (-40+10mm) and fines (-10mm) will be segregated, which will in turn be transported to the Roxy railway siding at a distance of around 22 km by 20t trucks. Overburden/ Inter-burden will be loaded through 0.9-1.0 cum excavator into 10 t/ 20t dumpers for its disposal in the proposed dump. Rock breakers will be used in case of large size boulders. The O/B to be generated during the course of mining operation shall be stacked separately at the dumping site. As ML 139 and ML 130 of SAIL share common boundary and the boundary is mineralized, the lessee wants to mine out the common boundary for which an application has been made to DGMS for their permission.

5.2 Population Projection Temporary influx of people will be there as the managerial and supervisory staff will be recruited from outside the area. 5.3 Land use Planning At the end of the ensuing plan period a total area of 3.8 hectare is to be degraded under mining. During conceptual period an area of 18.73 hectare will be mined out. As the total area is yet to be explored, no backfilling proposal has been proposed in this plan period.

However, based on outcome of the proposed exploration, suitable planning would be made for reclamation of the quarries. Conceptually, the exhausted quarries will be backfilled using the generated wastes and the backfilled areas will be rehabilitated through plantation. The detailed planning can be made in the next scheme period.

The land use pattern at the conceptual period is as follows:

5.4 Assessment of Infrastructure demand (Physical & Social) On the basis of the preliminary site visit, the infrastructure demand in the village was assessed on the basis of need and priority. Physical Infrastructure The road facility is already available. The same will be continued to use during mining development and operations and the same will be maintained regularly. Public buildings are not present in the core area of mine. Most of the laborers will be engaged from the villages adjacent to lease area. Hence transport facilities for commutation of mine workers are not required. Social Infrastructure An occupational health unit will be constituted and the following measures will be adopted: 1. Periodical Medical Checkup program for all the workers and first-aid box with necessary equipment will be provided. 2. Training for workers regarding occupational hazards and 3. Use of Safety equipment i.e. dusts mask, safety shoes, gloves etc. 5.4 Amenities/Facilities The site services play a vital role in management of mines. The following site services will be provided within Kalta Iron ore mine to facilitate mining operation. i. All statutory services like first aid center, drinking water station, rest shelters, sheds will be provided in close proximity of mines being developed. ii. Electricity/ DG will be provided in camp, office, and mines. iii. There will be an ambulance in the mine which in case of emergency can take the patient to the nearest hospital. iv. There will be water supply system for drinking water from the dug well/ tube well and distributed to camp, colony mines etc v. An office of mines manager will be provided. vi. Barbil Railway Station is about 19 km in NE direction. vii. NH-215 is about 5.5 km in SE direction.

6. PROPOSED INFRASTRUCTURE 6.1 Industrial Area (Processing Area) No infrastructure is proposed. 6.2 Residential Area (Non Processing Area) All the Services and facilities required under the Mine Act (and the regulations, Rules and Bye- laws made there under) have been provided at the Kalta Mine. These include a Vocational Training Centre, Rest Shelters, First Aid Stations, a Canteen, an Explosive Magazines, etc. In addition, a site office and public conveniences are also provided.

6.3 Green Belt Total area of green belt to be developed would be 33% of mine lease and its surrounding area. As the mine lease area is 25.981 ha so plantation would be around 8.573 ha.  Green Belt will be developed around the lease boundary, haul roads and plantation will be done on undisturbed area, safety zone, reclaimed area, dump site, workshop & mine office, etc.  Local species will be planted in consultation with Forest Department.  Local plant species like Mangifera indica, Psidium guajava, Mangifera indica, Psidium guajava etc. will be planted. Year wise proposed plantation details Year Area (m2) Type of saplings No. of saplings Distance between saplings(m x m) 2016-17 1132 Mangifera indica 181 2.5 x 2.5 2017-18 1213 Psidium guajava 194 2.5 x 2.5 2018-19 1105 Mangifera indica 177 2.5 x 2.5 2019-20 1125 Psidium guajava 180 2.5 x 2.5 Total 4575 Psidium guajava 732

The maintenance such as suitable fencing, watering, replacement of dead plants etc. is being taken regularly and activity will continue in future for better survival rate. 6.4 Social Infrastructure

The mining employment will increase the income levels of people living in the vicinity of lease area. In addition, creation of comparatively well paid jobs in the area has generated not only sizeable trade in household supplies (including vegetables, milk, food, textile, etc) but also some household employment. It has also generated demand for tertiary services like transport and repair shops. The infrastructure of the area, like roads, public transport and electricity supply, will also improved after the commencement of upcoming mining operation. The Kalta Mine has a Field Maintenance and Repair Shop for routine jobs. Major repairs are undertaken at neighboring Barsua Mine of the Company. 6.5 Connectivity

7. REHABILITATION AND RESETTLEMENT (R&R) PLAN 7.1 Policy to be Adopted (Central/State) in Respect of the Project Affected Persons Including Home Oustees, Land Oustees and Landless Laborers (Brief outline to be given) There are no public buildings, palaces or monuments inside the Mine lease area. Hence there is no issue of rehabilitation and resettlement of Project affected people. 8 PROJECT SCHEDULE & COST ESTIMATES 8.1 Likely Date of Start of Construction and Likely Date of Completion No construction activities are proposed presently. The mining activity will commence only after receiving environmental clearance and other statutory clearance from the authority. 8.2 Estimated Project Cost Along With Analysis In Terms of Economic Viability of the Project Estimated project cost is Rs.10.08 Crores. The mine will be Eco-Friendly. The necessary funds under Capital and Revenue head shall be provided to cater to the needs of mitigative measures for Environmental Pollution Control, Environmental Monitoring, Plantation, CSR Activities etc.

9.0 ANALYSIS OF PROPOSAL The proposed mine will bring about economic benefits to the state in the form of Royalty. The local people will be benefitted by getting direct and indirect employment opportunities. The iron ore is in high demand at the local market for real estate industry. Mining of Iron ore at near Village Kalta of Sundergarh district will be able to meet the local demand to a great extent. Similarly industries depended upon iron ore will be benefitted by the commencement of mining at the Village Kalta of Sundergarh district. The project will provide livelihood to the poorest section of the society/economically backward population and tribal‟s in the area. It will provide employment to the people residing in the vicinity of mining, directly or indirectly. The mine management will also help nearby villages by providing aid to school, conducting medical and social awareness camps, helping in formation of self-help groups, etc. Thus the project will bring about socio- economic improvement of the area and will prove beneficial to the area.
