The mine is working since 1984 and has produced MT of coal and removed million m 3 of OB till This mine has the capacity to increase coal production by 4.0 MTPA without additional land requirement. Purpose of the report This application has been made as per the OM J-15012/30/2004.IA.II (M) dated for grant of prior Environmental Clearance (EC) for increased capacity by 4.0MTY of Khadia OCP to MTPA considering the following points. A B C D E F G H Khadia OCP has got the capability of producing coal by 4.0 MTPA higher than MTPA, with higher utilization of plant & machinery. The total leasehold as per earlier approved EMP is Ha (extra land is not required and the forestry and other clearances have already been obtained). No change in technology is proposed. No change in backfilling & land reclamation programme will take place. Khadia OCP has one of the best land reclamation plans and the same shall continue after including the increased capacity of the mine to MTPA also. The total approved manpower is 1452 (3 shift working), no increase in which is proposed. The grade of coal is grade G-8 (Calorific value in the range of Kcal / Kg) and the linkage of coal is to M/s Anapara B & C STPS of UPRVUNL. The mine-able coal reserves was estimated to be MT and the average stripping ratio is 4.23 m3/t. Approximately Million Tonne of mineable coal reserve is left to be mined as on Due to the increasing demand of coal for the nation, it is requested to consider the proposal for grant of environmental clearance from MOEF for increased capacity of 14.0 MTPA (from MTPA normative capacity to increased capacity of 14.0 MTPA).

7 C. Ambient Air Quality Impact Prediction through Modeling: Except RPM (PM10) level no other parameter will be increased which is a major emission from various opencast mining activities. An ambient air quality impact prediction (AAQIP) for enhanced production of 14.0 Mtpa has been predicted by using FDM model. This AAQIP reveals that, the increase in RPM (PM10) level will be marginal and within permissible limit. The AAQIP details are enclosed as Annexure -II. The predicted and Monitored 24 hourly average PM10 Concentration Levels at Various Receptors ( mtpa) are given below: Predicted and Monitored 24 hourly average PM10 Concentration Levels at Various Receptors ( mtpa) 24 Hours average PM 10 concentration (µg/ m 3 ) Receptor Monitored / Baseline value Change in values without control measures (prediction) Change in values with control measures (prediction) Total concentration without control measures Total concentration with control measures Permissible Limits Auri Village Khadia Substation Khadia Guest House Chilkatand Basti Kohroul Village Noise Level status Noise Level Sites and their rationale: i) Mine Site (KHN1) To assess the noise level in mine site due to mining activities. The noise levels were recorded in the mine where all mining activities are in progress. ii) OB Workshop (KHN2) To assess the noise generated in the OB workshop due to maintenance and mining activities also, noise levels were recorded in the workshop. A-7

8 iii) Coal Workshop (KHN3) To assess the noise generated in the workshop due to maintenance of HEMM and it is nearer to the mine and so the noise levels from mining activities were recorded in the coal workshop. Iv) Colony (KHN4) To assess the noise level in the residential, noise levels were recorded during day as well as night time in the colony Summary of the observations and noise level measurements are given in Table No-3. Water quality status Location of Sampling Stations and their rationale: i) Inlet of ETP (KHW1) CHP generate waste water is tested before treatment at ETP to assess the effluent quality. This location has been selected to monitor the quality of CHP effluent ii) iii) iv) Outlet point of ETP (KHW2) This location has been selected to monitor the discharge quality of treated effluent through ETP. Outlet point of STP (KHW3) This site was selected to assess the quality of effluent discharged from sewage treatment plant into natural stream. Drinking water (IWSS) (KHW4) This site was selected to assess the quality of water being supplied from IWSS to the Project Colony. Water quality data are given in Table No-2. Also, the ground water levels and quality monitoring locations in the project are given in Plate 4. and results are in Table 4. 4 DETAIL OF ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION MEASURES Air Pollution Control Sources of air pollution The main sources of air pollution are identified as- 1) Drilling & blasting in coal & OB benches. 2) Coal & OB transportation inside the mine. 3) Coal crushing & conveying from the mine. 4) Coal handling activities. A-8

Ambient Air Quality Control Measures Air pollution control measures A movable water sprinkling system has been provided to check dust emissions from various parts of mine. (a) 20 KL water tanker : 5 nos. (departmental) b) 6 KL water tanker : 7 nos. (outsourcing) At all transfer points of conveyor system water sprinkling system are available. Vehicles are regularly being maintained to control the emissions. Coal transportation is being done in covered trucks. The haul road is being graded regularly in order to make it smooth. Coal before being loaded into tippers is watered properly to avoid generation of dust in course of transportation. Major coal transport is made through MGR railway system. Dust extractors have been provided and made operative in drills. Arrangement of wet drilling has also been made at Project level. Dust is controlled regularly by spraying water at Haul road, transfer point etc. Persons working in industrial have been provided with protective respiratory device. Regular training is being imparted to inculcate safety and health aspect. Each person working in or about the mine is being examined periodically by Doctor trained in occupational health services. Water Pollution Control Sources of water pollution Likely sources of water pollution from this project along with the type of pollutants are as follows: (i) Sanitary (domestic) waste water : Suspended solids and BOD. (ii) wastewater from workshop : Suspended solids, oil & grease; (iii) Waste water from mine : Suspended solids of coal, clay and oil; (iv) Surface run-off passing through coal stockpiles (v) Storm water from leasehold and built-up A-9 : Suspended solids; : Suspended solids. Effective water pollution control measures shall be taken as necessary keeping the following point. Sufficient safeguards have been taken to make the project eco-friendly from water pollution control point of view.

10 Recycling of wastewater at some sources after appropriate treatment to the extent possible. Conforming to the limits of the General Standards for discharge of environmental pollutants for the quality of the treated effluents. The mitigation measures to be adopted in this project are given below: Water Quality Management: Water pollution control measures Catch drains and siltation ponds of sufficient size have been constructed to arrest the silt and sediment. The clean water so collected is being utilized for watering mine, roads, green belt developments etc. The drains are being regularly de-silted and maintained properly. Sufficient sump capacity has been provided to have adequate retention period to allow proper settling of silt. Sufficient check dam shall be maintained in the toe of dump to arrest silting of sump. The effluent from workshop, CHP and Mine discharge is being treated in existing Effluent Treatment Plant of 1600m 3 /hr (38.4 MLD) capacity. The Project has already constructed a Sewerage Treatment Plant (STP) of 1.5 MLD capacity for treatment of domestic effluent from colony. The STP is in operation and treated effluent is used for horticulture purposes. Also, the buildings are having facilities of septic tank and soak pit. Rain Water Harvesting In order to augment ground water resource, artificial ground water recharge measures have been taken. Further, numerous numbers of hand pumps, wells and ponds have been provided in nearby villages to meet the water requirements of villagers, animals and plants. Additional Water requirement for the proposed MTPA (4.0 MTPA Increased Capacity) of Khadia OCP Due to increase in capacity there will be slight increase in water requirement for industrial (haul road dust suppression).this increase of water requirement will be met by mine water and treated water from ETP. Noise Level Management: The mining operation may cause noise nuisance if adequate precautions are not taken to keep the noise level within limits. Environment standards for coal mines stipulates that noise level in operational/ working zone shall not exceed 85 db(a) Leq. The following measures therefore, have been envisaged to reduce the noise Level to protect the workers from noise hazard and to adhere to the Environmental standards in respect of noise. Use of equipment with arrangements for absorbing the operational noise. A-10

11 Foundations of vibrating equipment to be designed with isolators to prevent vibrations so that the noise level does not exceed 85 db(a) Leq. Controlled blasting is undertaken under supervision of the blasting officer. Proper blast design is prepared to control ground vibration and to arrest fly rocks, air trashes and boulders. Blasting is done with the use of soft tubes. Use of insulated cabins for operators Use of rubber/ polymer liners in chutes and hoppers Use of ear muffs by workers in the zone of high noise source (if any) Plantation of trees around the plant. Routine maintenance of HEMM. Regular maintenance with prompt replacement of worn-out parts. Land Requirement & Management The earlier approved Khadia OCP involved land requirement of 1640 Ha, no increase in land requirement is proposed for increase in coal production. There will be no change in total OB quantity, dump, final dump plan and dumping strategy due to increase inak production from Mtpa to14.00 Mtpa. Modalities for Technical & Biological reclamation will be remain same as mentioned in approved EMP (10.00 Mtpa) of Khadia OCP.

14 i) On Plain nos. ii) on OB Dump nos. Socio-Economic Issues: The project has given a boost to the economy of the by providing primary and secondary employment to local people. The infra-structural facilities provided by the project are benefitting local villagers also. The mine closure activity is likely to significantly reduce the impact of industrial activity on the land apart from increasing the green cover and surface water availability. The standard of living of the local inhabitants has improved significantly due to indirect employment and service opportunities. Resettlement & Rehabilitation of PAPs As per earlier proposals of MTPA of Khadia OCP, 569 PAFs were proposed to be rehabilitated. The rehabilitation & resettlement has been completed. There is no issue of R&R in the present proposal. Corporate Social Responsibility Corporate Social Responsibility (CSR) is taken up at Khadia Project level. Different villages falling in core zone and adjoining s are benefited through CSR activities run at project level. The nature of benefits include maintenance of ponds and community buildings, well digging and renovation, road repair, renovation of schools and construction of boundary wall, medical camps, water supply, skill development for employment generation etc. The expenditure on CSR activities in Khadia Area in last few years is given below: Year Proposed Amount Spent (Rs. Lakh) As per the CIL CSR policy of June-2014, the fund for the CSR should be allocated based on 2% of the average net profit of the company for the three immediate preceding financial years or Rs.2/- per tonne of coal production of previous year whichever is higher. Out of above, 80% would be allocated for CSR activities to be carried out within the radius of 25 Kms of the project site and balance 20% would be allocated for carrying out CSR activities by company in the State to which it belongs. Detail of Last Public Hearing The last public hearings for approval of MTPA project was held on Samudaik Bhawan, Waidhan, Singrauli (MP) by MPSPCB and on at Collectrate Sabhagar, District Headquarters,Lodhi, Sonebhadra (UP) by UPSPCB. Detail of Public Hearing is enclosed as Annexure -V. 5 Analysis of Alternatives Not applicable, as this is an increase in production capacity by 4.0 MTPA of existing opencast mine. 6 Environmental Monitoring Program For effective implementation, a time bound action plan for environmental management including all aspects is being followed by the project. Samples for study of ambient air quality, water quality, ground water level and noise level are collected and tested quarterly at strategic places representing all the categories of location. Refer Plate 2,& 5 for A-14
