SIX MONTHLY PROGRESS REPORT ON THE IMPLEMENTATION OF ENVIRONMENTAL CLEARANCE CONDITIONS BY MoEF (FOR THE PERIOD OCTOBER 13 TO MARCH 14) Name of the Project: - Hingula Open Cast Project. No. & Date of MOEF clearance letter:-j.11015 / 39/96-IA-II, Dated:-January 06, 1997. J.11015 / 136/2007-IA-II (M), Dated:-October 31, 2007. A. SPECIFIC CONDITION: CN DETAILS OF SPECIFIC CONDITIONS No. 1 Tops soil, if any should be stacked with proper slope at earmarked site, should not be kept active, and shall be used for reclamation and development of green belt. 2 OB shall be simultaneously backfilled in the de-coaled area, No new OB dump shall be create for the OB to be generated in the balance life of mine. 3 The embankment constructed along the Singhara Jhor shall be stabilized by vegetation. 4 Monitoring and management of existing reclaimed dump sites should continue until the vegetation becomes self-sustaining. 5 Catch drains and siltation ponds of appropriate size should be constructed to arrest silt and sediment flows from soil and OB dumps. The water so collected should be utilized for watering the mine area, roads, greenbelt dev. ect. The drain should be regularly de-silted and maintained properly. Garland drains and sump capacity should be designed keeping 50% safety margin. Over and above the rainfall Sump capacity should also provided adequate retention period to allow proper settling of silt materials. STATUS OF IMPLEMENTATION OF THE CONDITION Top soil is being stacked separately as per guideline of MoEF and will be used only for reclamation & plantation. No new ext. dump is being created, all OB generated are being backfilled.. Biological reclamation of the dumps is executed through Orissa Forest Development Corporation. Constant monitoring & management of these dumps are being ensured till it become self sustaining. Catch drains and siltation ponds have been provided of appropriate size as per requirement. All the collected water is led into the mine sump, which acts as mine water reservoir. Water for all industrial uses such as watering in the mines area, for dust suppression in road, watering in plantation etc. is met from this reservoir.
6 Dimension of the retaining wall at the toe of the dumps and OB benches within the mine to cheek run-off and siltation should be based on the rainfall data. 7 Crushers at the CHP should be operated with high efficiency bag filters. Water sprinkling system should be provided to check fugitive emissions from crushing operations, conveyor system, haulage roads, transfer points, etc. And fixed type sprinklers are provided all along the conveyors to arrest fugitive emissions. 8 Drills should be wet operated. Roads shall be metal topped and mechanical sweepers shall be regularly deployed to clear the dust off the main approach and mineral transportation roads. Water sprinkling (fixed and mist type, mobile) shall be regularly done along the main haul roads. 9. Mining operations for the expansion project shall not involve drilling, blasting and crushing operations as a result of use of surface miner. 10 The total area brought under afforestation shall be not less than 435.18 ha. which includes backfilled area (201.68ha), OB dumps (17.34ha), along ML boundary (7.43ha), infrastructure and along roads (14km). Safety zone and vacant area (173.75), area around infrastructure (30.58 ha) and area in township outside the lease (4.40 ha) by planting native species in consultation with the local DEO/Agriculture Department. The density of the trees should be around 2500 plants per ha. 11 A progressive Mine Closure Plan shall be implemented and OB generated shall be simultaneously backfilled so as to backfill and reclaim 201.68 ha of de-coaled area and the balance 55.20 ha being converted into a water reservoir shall be protected by peripheral fencing and the upper benches of the reservoir shall be gently sloped and stabilized with plantation. 12 Regular monitoring of ground water level & qualities should be carried out by establishing a network of existing wells and construction of new peizometers, The The retaining wall at the toe of the dump has been construction taking into consideration of rainfall data. CHP is operated with 130 nos. of mister type sprinklers and along with fixed type sprinklers provided all along the conveyor and in CHP premises to arrest the fugitive emission. As around 90% of coal is produced through surface miner. Hence the CHP is not used for crushing. Wet drilling is being done, permanent haul roads/coal transportation roads are already completed with blacktopping 4 nos 28KL mobile water sprinkler and 5 nos 8KL are engaged departmentally and contractually for water spraying in three shifts a day respectively in mines area and coal transportation road. Use of surface miner is always preferred as practicably as possible& utmost care is being taken to do 100% coal production through surface miner. In the last year (2013-14) more than 90% of coal production done though surface miner. Till date total area planted is 30.15 Ha. and total nos. of plantation is 68,392 nos. As per proposed expansion program the existing backfilled area will be re-handled accordingly as per new schedule of backfilling the plantation will be done. For the year 2014-15 total plantation proposed is 9.33 Ha out of which 1.33 Ha in external dump and 4 ha in backfilled area and 4ha along the embankment of diverted nalla. The progressive mine closure plan is being implemented. The total OB generated is being simultaneously backfilled.final plan approved by ministry. Ground water level monitoring is carried out in January, April, August & November.
monitoring for quality should be done four times a year in pre-monsoon (May), monsoon (August), post monsoon (November) and winter (January) season and for quantity in May. Data thus collected should be submitted to the Ministry of Environment & Forests and to the Central Pollution Control Board quarterly with in one month of monitoring. 13. The company shall put up artificial groundwater recharge measures for augmentation of ground water resources. The project authority should meet water requirement of near by village(s) in case the village wells go dry due to dewatering of mine. 14. Sewage treatment plant should be installed in the existing colony.etp should also be provided for workshop and CHP wastewater. Physically. Ground water quality monitoring is done on monthly basis and report is enclosed herewith for reference. The peripheral village ponds are cleaned and deepened before monsoon. Mine sumps, where the entire mine water is collected will also accelerate the recharge of ground water. Water supply to the peripheral villages is made during summer season as per demand and requirement in consultation with the district administrations. STP is not available as no separate colony is being provided for Hingula OCP. ETP - 270 M 3 /per day capacity is existing, which is adequate as per required standard, after treatment the water is being reused for vehicle working. 15. Besides carrying out regular periodic health check up of the workers, 10% of the workers identified from work force engaged in active mining operations shall be subjected to health check up for occupational diseases and hearing impairment, if any, through an agency such as NIOH, Ahmedabad within a period of one year and the result reported to the Ministry and to DGMS. 16. For monitoring land use pattern and for post mining land use, a time series of land use Maps, based on satellite imagery (on a scale of 1:5000) of the core zone and buffer zone from the start of the project until and of mine life shall be prepared once in 3 years (for any one particular season which is consistent in the time series), and the report submitted to MoEF and Regional office at Bhubaneswar. Periodical Medical examination of every worker is done at 5 years interval. Occupational health cell is established. Well equipped dispensary with staff is also established. Workers showing abnormal symptoms are identified and subjected to test and treatment accordingly. Satellite images are being taken regularly by M/s CMPDIL.
