PART-G Impact of the pollution abatement measure taken on conservation of natural resources and on the cost of production.
Pollution control measures have helped to a great extent in conservation of natural
resources like water, soil, air, flora & fauna. Moreover, plantation has helped in
reducing pollution & also preventing soil erosion form OB dumps.
Environmental expenditure 1. Plantation –11.43 Lakhs, 2. Consent renewal –12.5
Lakhs, 3. Rainwater harvesting- 2 lakhs, 5. Environmental monitoring by CMPDI-
79.5 Lakhs, 6. Environmental monitoring by MPPCB -0.87 Lakhs, 7. Water
sprinkling -50 Lakhs, Total Aprrox. Expenditure - 154.3 lakhs
Production cost increased marginally.
---------------------------------------------------------------------------------------------------------------------
PART-H
Additional measures/investment proposals for environmental protection including abatement of pollution, prevention of pollution.
Environmental monitoring will be done at the cost of Rs lakhs (Approx). Technical & Biological reclamation of OB dumps will be carried out. Recently we have provided rain water harvesting system at project office of DOCM for ground water recharge. Also mine water is being supplied to two ponds of Deohara village near DOCM which not only helps villagers to meet their day to day requirements but also helps to a great extent in ground water recharge. ---------------------------------------------------------------------------------------------------------------------
PART-I Any other particulars for improving the quality of the environment.
Plantation has been done at the mine & OB dumps by MPRVVN Ltd. Which helped in stabilization of dumps and improvement of environment. Mine is distributing free LPG cylinder to employees through co-operative Society. It will reduce the burning of coal for in houses purpose. Celebration of World environment day to increase awareness on environment. Training program for executive at outside of company & also attended work shop organized by MPPCB. ---------------------------------------------------------------------------------------------------------------------
