PART - F

PLEASE SPECIFY THE CHARACTERISATION (IN TERMS OF COMPOSITION AND QUANTUM) OF HAZARDOUS AS WELL AS SOLID WASTE AND INDICATE THE DISPOSAL PRACTICE ADOPTED FOR BOTH THESE CATEGORIES OF WASTES.

F. 1 Hazardous Waste:

Hazardous wastes are mainly oily solid waste from HEMM Workshop and used oil from the HEMMs. These wastes comprise mainly oil & grease in characteristics, which is considered as hazardous. During the current financial year 2016-17, about 252.635 KL used oil including emulsified oil has been recovered from oil and grease trap and other sections. In the year 2016-17 300.00 KL of category 5.1 oil waste was disposed through an authorized TSDF.

30 t of Category 5.2 waste (Wastes/ Residues containing oil) was also recovered in the financial year 2016-17.

Used oil generated from different sections and workshop is collected by trolley and drums system and returned to the stores. It is then centrally auctioned through ANTRAS system Pvt. Ltd., Banglore and sold to authorized recycler. Oily solid wastes are being sent to M.P. waste management project, Pithampur, Distt. Dhar (M.P.) for disposal.

The project has obtained the authorisation for generation, storage and disposal of hazardous waste from the Madhya Pradesh Pollution Control Board under Hazardous & Other Wastes (Management & Transboundary Movement) Amendment Rules, 2016.

F.2 Solid Wastes:

One of the solid waste generated from the opencast mine is overburden material including topsoil, which consists of three distinct materials: i) mixture of fine grain sand stone, clay and shale (about 15%). ii) weathered porous grained (ferruginuous) sand stone (about 30%) iii) porous grained white sand stone (about 55%).

During the year, 2016-17, about 53.365 Mm3 of overburden was generated by the project. Dumping of the excavated OB material is being done in earmarked four numbers of internal dump sites and two numbers of external dump sites as per the approved EMP (15 MTY). This dumping is being done in benches of height not exceeding 30 m and ultimate height not exceeding 270 m from lowest coal seam floor level and 90 m from the average ground level in case of internal and external dumps respectively. Thereafter these dumps are being reclaimed technically by levelling with dozer and grader while keeping slope of the dump to be less than 280. Appropriate plant species are grown on the dump slopes to stabilise them and to prevent soil erosion. Till March-2017, 315.00 ha of external and internal OB dump have been reclaimed technically and 304 Ha biologically.

CMPDI


F.3 Top Soil: The mine lease area and its surrounding area is undulating and hilly terrain.

Hence, at Nigahi OCP, top soil is available in patches. The prevalent practice is to reuse the top soil, whatsoever is generated, readily for biological reclamation of OB dumps.

The top soil which need to be stored is being stock-piled on the designated top soil

dump i.e., top soil storage site on the north side of the top of the western internal dump (Plate-III).

The quantity of top soil generated in the previous two financial years is as follows:

Year Quantity of topsoil in m3

2015-16 5,800

2016-17 2,00,000

PART – G

IMPACT OF POLLUTION ABATEMENT MEASURES ON CONSERVATION OF NATURAL RESOURCES AND ON THE COST OF PRODUCTION

G.1 A detailed EIA/EMP was prepared for Environmental Clearance for 15.00 Mtpa Coal production by RI-VI of CMPDI in 2006. In order to prevent any damage to the Environment, several measures were suggested in the Environment management plan to keep the pollution within permissible limits. The following measures are being followed:

Air Pollution Control Measures:

OEM water tankers (two each of 28 KL and 70 KL capacity), converted water tankers (7 nos. of 37 KL capacity) are deployed for water spraying on haul roads and other required areas.

Besides the above mentioned departmental arrangement, the outsourcing management has its own fleet of water tankers for water spraying on haul roads and are tabulated as below:

No. of water tankers

Capacity (KL)

Approximate no. of trips/ day

13 12 110

7 18

1 28

2 15

Water spraying arrangement through nozzles has been done near unloading point

of receiving pit and loading point of SILO.

Vegetation/ Plantation have been carried out over the surface of dumps.

Dust collectors are provided in drills.

Green belts around colony, quarries, OB dumps, and industrial area has been provided.

50000 plants were planted on OB slopes in slope area of 20 Ha in 2016-17. Water Pollution Control Measures:

a) Waste water from Workshop and CHP: It is being treated in two numbers of ETPs of capacities 4.0 MLD and 10.5 MLD constructed for Workshop and CHP effluents respectively. The method of treatment used in these ETPs is chemical treatment i.e. Coagulation and Flocculation by using Alum as the coagulant in the presence of lime and poly-electrolyte.

CMPDI


b) Domestic waste water: It is being treated in a STP of capacity 3.0 MLD. The method of treatment is biological treatment i.e. biological oxidation of waste water by aerobic biomass.

c) Discharged Mine Water: At present mine water is partially treated in three stages. In the first stage sedimentation is carried out at Tri-junction sump, in the second stage it is carried out at Old Bareja Reservoir and in the final stage sedimentation is carried out at New Bareja reservoir. Moreover one ETP is proposed for mine water treatment.

Noise Pollution Control Measures:

The noise values are within permissible limits as per the noise monitoring report. The noise is mainly being produced during:

i) Drilling & blasting operation.

ii) Operation of HEMM like dragline, dumpers, dozers, shovels and other motor vehicle.

iii) Operation of CHP due to crushing, screening, loading and unloading operation.

iv) Workshop operation.

The following measures are being adopted to keep the noise pollution within limits:-

i) Blasting operation are carried out in between 1.00 PM to 2.00 PM during which all workers are evacuated from the mine area.

ii) Routine maintenance of HEMM is done in the project. Operators are provided A/C cabin which acts as a noise insulator.

iii) Operators and workmen are provided earmuffs and earplugs as and when required.

iv) Colony has been constructed at a distance of 4 km approximately from the mine area to minimise the impact of noise due to mining activity. Curtain plantation is done between the mine area and colony which acts as noise barrier.

v) In CHP crusher boxes are enclosed. Gyratory crushers are employed which make minimum noise. At both loading and unloading points, air-conditioned enclosed cabins are provided for work persons employed therein.

G.2 Land Reclamation:

The removal and management of OB from mine has been outlined in Part - F of the report. The project has carried out massive afforestation in the area. Up to March-2017, about 31.29 Lakhs saplings have been planted in Nigahi area. A sum of Rs.4.66 Crores (approx) has been spent on environmental protection in the year 2016-17.

CMPDI


G.3 IMPACT OF POLLUTION CONTROL MEASURES ON COST OF PRODUCTION: As per environmental management plan the cost for environmental protection

measures is Rs. 8.58 per tonne of coal. G.4 Expenditure incurred on Environmental work and abatement of pollution in the

year 2015-2016 and 2016-2017 in Nigahi project are given in Table G-1 and G-2 respectively.

WATER QUALITY MONITORING

Location of sampling sites and their rationale (Refer Plate No-.II)

i) Inlet of W/S- ETP (NW1)

To assess the effluent quality of Workshop before treatment in workshop ETP.

ii) Treated water from W/S- ETP (NW2) To assess the effluent quality of Workshop discharge after treatment in ETP.

iii) Inlet of CHP- ETP (NW3) To assess the CHP effluent quality before treatment in CHP ETP

iv) Treated water from CHP's ETP (NW4) This location has been selected to monitor the discharge quality of CHP ETP after treatment.

v) Treated water from STP (NW5) This site has been selected for asses the quality of treated domestic effluent through STP.

vi) Tap Water of DPS School (NW6) This is the location of the Project for monitoring of Drinking Water.

vii) Hand Pump Water of Temporary Colony (NW7) This location is monitoring for underground water quality of Drinking Water

viii) Overflow from Bareja Siltation pond (NW8) The sampling site was selected to check the water quality of overflow during the monsoon and the seepage from this dam, which should conform to MOEF&CC SCH-VI Standards.

ix) Water near OB dump at east Section (NW10) This location is selected to monitor the surface water quality of mine water sump whose water is used for dust suppression.

x) Hand Pump Water of Amjhar School (NW11) This location is monitoring for underground water quality of Drinking Water.

Methodology of sampling and analysis

Water samples were collected as per standard practice. The effluent samples and Drinking water samples were collected and analysed for four/five parameters on fortnightly basis. The surface water sample and drinking water samples were collected and analysed for all parameters on quarterly basis. Parameters like pH, Temperature and Dissolved Oxygen were analysed on-site while collecting the samples. Thereafter the samples were preserved and analysed at the field laboratory located at RI-VI Office campus, as well as at the Environmental Laboratory at CMPDI (HQ), Ranchi.
