(a)-(b) : Yes Madam. Coal is washed in coal washeries to reduce ash content so that there is  less  fugitive  emission  in  the  air.  Coal  India  Limited  (CIL)  has  planned  to  set  up  15 washeries in its various subsidiaries to reduce the ash content in the coal.

(c): The  number  of  coal  washeries  currently  in  operation  in  CIL  is  15  with  a  total throughput capacity of 36.80 Mty, out of which 12 are coking coal washeries with capacity of 23.30 Mty, and 3 are Non-coking coal washeries with Capacity 13.50 Mty. The details are being given in the table below :-

The amount of coal above G-10 grade washed in washeries of CIL subsidiaries during the  year 2016-17 from April 2016  till Feb'2017 is 213369.15 tonnes.

(d): CIL  has  planned  to  set  up  15  Coal  washeries  in  the  first  phase  having  a  total capacity of 94.1 Mty, out of which 6 washeries are for Coking Coal with total capacity of 18.6 Mty and the remaining 9 are for Non-coking coal with total capacity 75.5 Mty.

In  addition  to  the  above,  5  more  new  washeries  (1  in  BCCL  &  4  in  CCL)  and  2  deshaling Plants (in BCCL) for coking coal are being envisaged to augment the supply of washed  metallurgical  coal.  Further  5  existing  coking  coal  washeries  (in  BCCL)  are planned  to  be  renovated  to  improve  capacity  utilization.  Overall  details  of  the  27 washeries are furnished in the table below:

(e): Washeries  are  set  up  to  control  the  ash  content  of  coal  to  reduce  air  pollution. However, during various operations in coal washeries, a lot of particulate matters and gaseous pollutants are generated causing an air pollution problem in the area. Hoppers of the crushing units and washery units are fitted with high efficiency bag filters and mist  spray  water  sprinkling  system  installed  and  operated  effectively  at  all  times  of operation  to  check  fugitive  emissions  from  crushing  operations,  transfer  points  of closed belt conveyor systems and transportation roads.

Three-tier green belt is being developed along the washery boundary and along transfer and  loading  points  and  railway  siding  to  mitigate  /  check  dust  pollution.  All  the washeries have been made Zero discharge. The same water is recycled again and again in the main process of the washery.
