3. Anticipated Impact on Air Quality due to increase in Peak Capacity and Proposed Mitigation Measures The coal production from the mine during the year 2013 – 14 was 6.4 MT (average of 19394 TPD) while OBR produced was 27.64 million m3 (average 83758 m3 / day. OB is being generated. The OB is being dumped internally while produced coal is transported to the Railway Siding at Sheetalpur, 5 kms away by road by 15 te capacity dumpers. The quantum of incremental impact on air quality has been assessed by running the Fugitive Dust Model (FDM) of the USEPA for which the worst scenario has been taken for the year 2016 – 17 with coal output at 12 MTY (36364 TPD) and OB generation at 81.26 Mcum (246242 m3/day). A new railway siding with conveyer belt system has been proposed within leasehold. Construction of railway siding is under process and it is expected to be functional by year 2016- 17, thus eliminating road transportation of coal, thereafter. The model has therefore been used to predict the incremental TSP at designated receptors where the baseline levels of TSP are known for 2 (two) scenarios, viz. Scenario A : Incremental impact for capacity enhancement from 8.0 MTY to 12.0 MTY keeping present road transportation of coal to Sheetalpur railway siding, 5 kms away, which is likely to be continued till 2016 – 17. Scenario B : Incremental impact for capacity enhancement from 8.0 MTY to 12.0 MTY after road transportation is done away with which is likely to be achieved after 2016 – 17 with the commissioning of the proposed railway siding at the mine.

CMPDI Job No. 111274 Observations: On comparing the two scenarios, it can be observed that the quantity of fugitive dust has reduced due to commissioning of proposed Railway Siding and transport of coal by conveyor belt.

The concentration of dust is relatively higher at one receptor, Training Centre which is located very close to mine workings and hence additional mitigation measures will be adopted as discussed below. The concentration of dust at other receptors is likely to remain well within the prescribed limit.

Air Pollution Control Measures Appropriate mitigation measures have been taken to contain the predicted level within prescribed level. These measures (both preventive and suppressive) are enumerated below: Source Category Present Mitigation Measures Additional Mitigation Measures Drilling Operation Wet drilling is being carried out.

CMPDI Job No. 111274 Vibration Study & Control

The peak particle velocity is a good indicator of the probability of damage to a structure. It is expressed in mm/sec. the peak particle velocity at any point depends mainly on the amount of charge exploded, radial distance from the blasting point to the station of observation and the geological conditions.

According to Indian Standard Bulletin No.6922 of 1973 (Reprinted April 1982 on part 4.1.1.1 and 4.1.1.2), in order to provide adequate safety, the peak particle velocity should not exceed the following limits. S/No. Particulars Velocity from Velocity from monitored imperial relation by suitable instrument (mm/sec) (mm/sec) 1 Soil, weathered 50 70 or soft rock 2 Hard Rock 70 100

It has been found that ground vibration is dependent on both particle velocity and frequency. The maximum damage to buildings due to blasting vibration occurs when blast frequency matches the natural frequency range of the buildings and when there is a mismatch between the ground vibration, frequency and natural frequency of buildings, very little energy is transmitted into the structure. The natural frequency of low rise (1-2 storey) residential structures is in a range of 3 to 12 Hz. These low frequencies are most predominant at greater distances from a blast point. High frequencies (about 40 Hz) above the fundamental natural frequencies of residential structure, allow a higher particle velocity limit.

As per the latest study by USBM, the safe blast vibration level (published in RI-8507 of 1988) are as follows: S/No. Type of structure Ground vibration (peak particle velocity mm/sec.)

At low frequency At high frequency (less than 40 Hz) (more than 40 Hz)

2 Other houses, plaster on wood construction 12.50 50 for interior walls.

CMPDI Job No. 111274 To protect the structural damage from blast induced ground vibration, DGMS has recommended the permissible standards of vibration vide DGMS (Tech.) circular no. 7 dated 29.09.97 as below – S/N. Type of Structure Peak particle velocity in mm/sec. Dominant excitation frequency (Hz) <8 Hz 8-25 Hz >25 Hz A Buildings/structures not belonging to owner i Domestic houses/ structures (Kuchha, 5 10 15 Brick, Cement) ii Object of historic importance and 2 5 10 sensitive structures iii Industrial buildings (RCC & Framed 10 20 25 structures) B Buildings belonging to owner with limited span of life i Domestic houses, structures (Kuchha, 10 15 25 Brick, Cement) ii Industrial structures 15 25 50

However, all structures eventually crack because of a variety of environmental stresses including humidity and temperature changes, settlement from consolidation and variations in ground moisture, wind and even water absorption from tree roots. Consequently, there may be no absolute minimum vibration limit. Control Measures

The blasting is scheduled only around future. 12 noon to 2.00 PM. The siren alert system is also practiced for safety purposes.

SOIL QUALITY ANALYSIS

Soil Quality Status at the time of Baseline Data Generation

Soil characteristics, erosion aspects, soil fertility etc., have direct bearing on the environment. Knowledge of soil parameters is essential for the planning and implementation of afforestation. Further, major mining activities affect the soil regime of the surrounding areas directly or indirectly. Hence, it becomes important to study the soil characteristics in the study area. Soil quality sampling locations

Keeping the above aspects in view, three different types of soil samples from agricultural land, barren land and O. B. dump were collected. Soil samples were collected by using auger from three horizons (30, 60 and 90 cm) below ground level and analysed for fertility and engineering parameters as per IS methods. The particulars of sampling locations are given below. Test Results for Sonepur Bazari OCP Date of Sampling- 23/05/2012 Sl.

Observation:

The soil quality in the project area appears to be good and would support plantation after suitable reclamation measures. Soil in the study area is found to be from slightly acidic to slightly basic at some places. Organic content was found high at some places due to coal.

The expansion project will not affect the parameters of soil quality.

Dumping Strategy & Dump Reclamation

It has been estimated that out of a total OB removal of 1037.58 M.cum, it will be possible to accommodate 744.58 M.cum inside the OCP excavation and the balance about 293 M.cum of OB has to be dumped in the three external dumps over an area 344.74 Ha. The total area earmarked for quarrying is about 1505 Ha. Although concurrent backfilling will be done, it will not be possible to backfill the entire quarried out area completely up to ground level, thus leaving a residual void in 504 Ha to a maximum depth of about 20 m. It has also been proposed to merge the external dumps with the internal dump to increase the capacity of external dumps. All the dumps have been proposed to be heightened up to 60 m above ground level. The present external OB dump is 65 Ha and internal dumping has been done in 225.31 Ha of the quarry area. Since these dumps are still largely active, reclamation and plantation could be carried out on 5 ha of external OB dump and 3 Ha of internal dump. Although, this is less than the plantation programme as envisaged in the approved EIA & EMP, the short – fall is likely to be covered up within the next 2 to 3 years. At the end of the mining, 344.74 ha of external OB dump and 1001.07 ha of backfilled area will be reclaimed and extensively planted. The revised plantation programme has been detailed in the section on land reclamation in the addendum EIA & EMP. Topsoil Topsoil is stacked properly with proper slope at earmarked site and is spread over external and internal dumps uniformly before reclamation of dumps. Total top soil removal since the inception of mine is 45 lakh cubic meters. It has been stored properly and will be used for spreading over internal and external OB dumps for reclamation.
