10 Steps taken for improving the environmental quality:. Rohini Opencast Project is a new Coal Project of Central Coalfields Limited. It falls in the South-West part of North Karnapura Coalfields and it is situated in Ranchi District of Jharkhand State. For improving different measures different measures are being taken. The following measures have been taken to control Air pollution: i) Regular sprinkling of water on haul roads and other roads. ii) Wetting of ROM Coal before crushing in CHP/FB. iii) Water sprinkling in coal stock is practiced. iv) Plantation on OB Dumps and in other vacant space. v) Blasting is done during congenial atmosphere. To control water pollution from workshop and mine, the following measures have been taken: i) Central sump on dip side act as settling pond. The clean water from the sump is pumped into the river Damodar. A portion of mine water is utilized for dust suppression on haul and transportation road. ii) iii) iv) One oil & grease tap is installed at workshop to arrest the oil & grease. The catch drain have been constructed around the foot of the OB dumps in order to collect surface run off water from the dumps and convey them to the settling ponds. Each house of the colony has been provided with septic tank with soak pit arrangement. The Project planted about 1,95,000 sapling on external & internal OB Dumps and both sides of roadways to minimize the noise level. In the mine, main sump is acting as a settling tank for settlement of sediments/particles. After settlement, maximum clear water is used for dust suppression by mobile sprinklers and fire fighting in Coal stock. In new workshop, workshop effluent to be passed through Oil & grease trap and clear water is further used for washing of HEMM. For domestic effluent, each & every quarter is equipped septic tank arrangement in the colony for treatment of the same.the year-wise plantation is given below: Name of Project Rohini OCP Year of Area in Category of No. of Main species Plantation Ha Land Plants OB dump Acacia, Gamhar, seasham subbabul,karanj, Kathsagwan, Chakundi, Eucalyptus, Ber, Amla, Emli, Babul Bamboo, Total ,05,000 Menzium, etc. 2015, awarded Mansoon
