1.0 INTRODUCTION
Essel Mining & Industries Ltd. (EMIL), a company of Aditya Birla Group
is operating Koira Iron Mines spreading over an area of 90.143 ha falls
under the jurisdiction of Koira, Nuagaon, Kadodihi & Harischandrapur
villages of Bonai Taluk, Sundergarh District, Odisha
Essel Mining & Industries Ltd. (EMIL) as part of statutory requirement
is monitoring various environmental parameters in an around the Koira
Iron Mines on continuous basis.
EMIL has retained M/s B S Environment Consultants Pvt Ltd. to carry
out the Environmental monitoring in and around the Mine. This report
presents the Half yearly Environmental monitoring data for the period
October’ 2011 – March’ 2012.
1.1 LOCATION OF THE MINE
The Koira Iron Mines is located near Koira, Nuagaon,Kadodihi &
Harischandrapur villages, BONAI Tehsil, Sundergarh district in Orissa.
Fig – 1 shows the Location Map of the mine. The mining lease area is
bounded by North latitude 210 53’ 40” to 210 54’20” and East longitude
850 13’ 20” to 850 14’20” and is covered in the Survey of India toposheet
73 G/1. The average altitude is about 590 m above MSL.
The mining lease is bounded by the leasehold area of M/s O.M.M Ltd.
and M/s S.D.Sharma on the North. The following is immediate vicinity
of the mine in all the four directions
North : The ML of M/s. S. D. Sharma lies on the northern fringes of
lease.
East: To the east of the mining lease site the village of Koira is located.
A small unnamed Nalla runs beside east of the mining lease site
from South to North direction.

South: The southern side of the mining lease site is partially agricultural
Land of Koira Village.
West: Village Nuagaon
Fig – 2 shows the Key plan of the mining lease.
The mining lease falls within the Singhbhum – Keonjhar-Bonai range of
hills roughly aligned from North South and the area is extremely rich in
mineral resources, especially iron ore and manganese.
The mining lease is located 1 km west of Koira Village and Roxy railway
siding is located 28 km in the South-West direction whereas, the
nearest Railway station on Barbil –Tatanagar branch of S.E Railway
Line at 35 km.
The district town of Sundergarh is located 190 km to the North – West
direction accessible by National Highway 215 and 23 and State
Highway No. 10. NH-215 runs about half a Km away from the mine
lease area.
The nearest railway station is located at the town of Barbil, which is 35
km away and is connected to the metropolis of Kolkata by a South-
Eastern railway line.
The site is well connected by metal road with steel cities Jamshedpur
(185 km), Rourkela (100 km) and district town Sundergarh (190 km).
The forests in the immediate vicinity of mining lease are distributed in
the Khajurdihi Reserve Forest to the South, the Toda and Sarkunda
Reserve Forest to the west and south-west, the Karo Reserve Forest to
the north and the Mendharmaruni Reserve Forest the north east. A
patch of dense mixed Sal jungle extends to about 1.5 km to the south-
east of the mining lease covering the Bhabani and the Kalmanga Pahars
(hills).The area falls within the watershed of the Karo nala, which flows
within 1 km to the North –west of the mining lease site.
Fig – 3 shows the 10 km radius (study area) around the mining lease
area.

From the above table it is observed that the Maximum concentration of
Respirable Particulate Matter (PM10) is in the range of 39 µg/m3 - 70µg/m3
and Fine Particulate Matter (PM2.5) is in the range of 14 µg/m3 - 31 µg/m3.
The PM10 and PM2.5 concentrations were found to be well within the limits of
NAAQS. The Maximum concentration of Sulphur Dioxide (SO2), Nitrous Oxide
(NOx) and Carbon Monoxide (CO) are well within the limits of NAAQS.The
