The source of water shall be mine water of Selected Dhori Quarry & from Integrated Water Supply System (IWSS) and no discharge is being done outside the project boundary. Water is also being recycled as much as practically possible and several measures are being undertaken for further augmentation of water resources in project command area.
Present Mine Inflow (Monsoon Season):
Since Selected Dhori GoM is an existing old mine of 2.25 MTPA rated capacity and working in combined Karo group of seams from VI to X and the expansion project of Selected Dhori GoM (Normative capacity: 8.25 MTPA and Peak capacity: 11.0 MTPA) proposes to exploit the same combined Karo group of seams from VI to X with the increase in production rate. All the seams and aquifers of the project has already been exposed and only rate of production has to increase with the same set of technology. Therefore mine inflow (non-monsoon) will remain the same for the future production target i.e. 1,305 m3/day.
Thus the proposed mine inflow (Monsoon+Non-monsoon)= 8346 m3/day.

Brief Details of Violation
Selected Dhori Opencast Project (2.25 MTPA) is an operating coal mine under Dhori Area of Central Coalfields Limited, which was started after obtaining Environmental Clearance vide No. J-11015/4/89-IA.II(M) from MoEFCC on 24.01.92. A proposal for Selected Dhori Group of mines for Normative Capacity 8.25 MTPA & Peak Capacity 11.00 MTPA was given TOR vide letter no J-11015/75/2013-IA.II(M) Dated 25th February, 2014. Public hearing was conducted on 27.08.2016. Meanwhile, the project has exceeded its EC capacity in previous years.

Assessment of Ecological Damage
The objective of the present chapter is to assess the ecological damage with respect to air, water, land and other environmental attributes due to excess production.
16 Impact on Air Environment
The project has achieved production of 6.62 MTPA & 3.97 Mm3 OB in the year 2013- 14. Impact on Air environment can be studied through the three month air quality monitoring data generated in the post monsoon season of 2013-14. The ground level concentrations as per the one season baseline data generated are as given below.
