EXECUTIVE SUMMARY

E-1 This Annual Environmental Statement has been prepared as per gazette

notification no.G.S.R. 329 (E) dated 13th March 1992 laid down by Ministry of

Environment and Forest. The Environmental Audit has been subsequently

renamed to “Environmental Statement " vide MOEF gazette notification no.

G.S.R. 386 (E) dated 22nd April 1993.

E-2 Jharkhand Opencast Project of Central Coalfields Limited is located in the West

Bokaro Coalfields of Ramgarh distt. Of Jharkhand State

E-3 Jharkhand Colliery is a working opencast mine of producing medium coking coal

from a number of quarries.

E-4 The Environmental Monitoring was carried out quarterly as per the guidelines of

Ministry of Environment & Forest (MOEF). The Environmental Monitoring

results for four quarter of 2013-14 are appended as Annexure.

E-5 Ambient air quality is monitored to study the level of air pollution. The main air

pollutant is Suspended Particulate Matter (SPM). It is difficult to quantify the

amount of air pollutants generated due to opencast mining. However , the results

show that SPM , SOx , NOx values are generally below permissible limits

prescribed by Ministry of Environment and Forest (MOEF).

E-6 Water is not directly used during mining for coal production. It percolates into the

working area during mining operation. However, water is consumed for other

purposes, mainly for haul road dust suppression and domestic purposes.

E-7 The noise levels recorded are generally below the permissible limits prescribed by

Ministry of Environment and Forest. There is no continuous high level sound.

E-8 Hazardous Waste is not produced either from mining operation or from any

pollution control facility. Solid waste produced from mining activities is

overburden material.

E-9 Regular measures are being taken to control air, water & noise pollutions

discussed in detail in part G, H & I of the Statement Form.


Chapter - 1

1.1 Introduction:

Jharkhand Colliery is a working opencast mine producing medium coking coal from a number of

quarries. Feasibility report was prepared in 1976 to produce 0.2 MTY of coal. Accordingly a semi

- mechanised mine was opened .The HEMMs have already reached their economic life. Also

coking coal demand of CCL has increased. Keeping this in view, a new project report has been

prepared by CMPDI to produce1.0 MTY of coal by opencast mining.

1.2 Location & Communication:

Jharkhand Block is located between latitude 230 46' 53" to 230 48' 29" N and longitude 850 36'

26" to 850 37' 23" E. The Laiyo Block is on the eastern side, Kedla Block on western side, Hurdag

Block on Northern side and Kedla south & Goes Block on Southern side.

Jharkhand Project is connected by 22 km long Charhi to Laiyo road joining NH - 33 at Charhi.

Another approach is through 12 km long all-weather road connecting Gidi Washery to Kedla and

crosses NH-33 near Kuju. The nearest railway station Danea on Gomoh- Barkakana loop line of

Eastern Railway, is 6 km by weather Kutcha road .

1.3 SALIENT FEATURES:

Jharkhand block is located in the north eastern part of West-Bokaro coalfields and lies on the

southern limb of the northern syncline. The total area of the block is 3.5 Sq. km. under different

leasehold.

The total mineable reserve in this sector has been estimated as 21.5 MT and total volume of OB to

be removed has been estimated to be 47.0 Mm³with stripping ratio of 2.19 m³/Te.

The life of the project has been estimated as 25 years. Overall quality of product is W-IV. Kedla

washery is to be fed from this project.

Total estimated land for this project is 323.88 Ha. This includes 68.22 Ha. Of forest land in safety

zone which will not be degraded hence not to be acquired.

1.4 TOPOGRAPHY & DRAINAGE

Chutua nalla flowing from west to east divides the Jharkhand block in two parts. South of chutua

nallah, where the proposed quarry has been identified is gently undulating with occasional

sandstone ridges and mounds. The maximum and minimum elevations are + 374m and + 318 m

above m.s.l. respectively, in south chutua nalla. The area north of Chutuah nalla is more or less flat

with thick alluvium deposits.

Bokaro river flows from west to east at distance of 2 Km. from southern boundary of the block.

Eastern flowing Chutuah nallah, a prominent tributary, joins the Bokaro River at 1.6 Km, east of

Laiyo. Several small nallah traversing the area , joins the Bokaro river & Chutuah nallah.

Chutuah nallah is more or less perennial for the greater part of the year excepting in the hot

summer days.

1.5 EMP STATUS

A comprehensive Environmental management Plan (EMP) for this project was formulated by RI-

III of CMPDIL in Dec`92 and submitted to the Ministry of Environment & Forest (MOEF) . The

EMP is approved by Ministry of Environment & Forest (MOEF) in June `95 subjected to

compensatory afforestation.

reasons

Water i.About 169 lts/day mine effluent discharged

outside.

ii.Workshop 7.0 lts/day

iii.Colony 90.00 lts./day.The analysis results

are given in Annexure

The analysis results reveal that most of the

parameters are below permissible limits prescribed

by MoEF as General Standards for Class 'A' effluent

(Effluent discharged into inland surface water).

Air It is difficult to quantify the amount of air

pollutants. The main air pollutant is

suspended particulate matter (SPM). The air

quality results are appended as Annexure.

Ambient air quality results show that SO2, NOx

values were within prescribed limits.

Noise The high noise in mining area owes its

origin in and around excavation & material

handling sites. There is no continuous sound

frequency of impulsive nature. Ambient

noise quality report is appended as

Annexure.

Noise Quality Report shows the results are within

permissible limits.

PART - F

PLEASE SPECIFY THE CHARACTERISTICS (IN TERMS OF

CONCENTRATION AND QUANTUM) OF HAZARDOUS AS WELL AS SOLID

WASTES AND INDICATE THE DISPOSAL PRACTICE ADOPTED FOR BOTH

THESE CATEGORIES OF WASTES

1. HAZARDOUS WASTES: Hazardous wastes are not being produced either from mining operation or from any pollution

control facilities.

2. SOLID WASTES : During opencast mining, overburden produced as solid wastes temporarily as these materials are

used for land reclamation. During the year 2013-14, 1.27 Million cubic meter of overburden was

generated. The overburden materials are more or less homogeneous comprising mainly shale,

sand, silt and clay, & gravel.

3. DISPOSAL PRACTICE

Presently, the O.B. material is being filled in de-coaled area of quarry and as external dump.

PART – G

IMPACT OF POLLUTION CONTROL MEASURES ON CONSERVATION OF NATURAL RESOURCES

AND CONSEQUENTLY ON COST OF PRODUCTION

In order to carry out mining in an eco-friendly manner, following pollution control measures have

been implemented.

1.0 AIR POLLUTION CONTROL MEASURES :

The following measures have been taken to control air pollution:

(i) Regular sprinkling of water on haul roads and other roads.

(ii) Water sprinkling on coal stock.

(iii) Plantation along the haul road and in other vacant space.

(iv) All necessary precautions will be taken during drilling, blasting, loading & transporting operations.

2.0 WATER POLLUTION CONTROL MEASURES:

The following measures have been taken to control water pollution from the mine:

i. The mine water is allowed to settle in sump before pumping to natural drains. Some of

mine water is also used for haul road dust suppression, in workshop & in fire fighting in

the mine.

ii. The catch drains has been constructed around the foot of the O.B. dumps in order to

collect surface run-off water from the dumps and convey them to the settling ponds.

(iii) An Oil & grease trap and settling ponds are proposed in the workshop to prevent water

pollution.

(iv) Colony & other service building are provided with septic tank & soak pit.

(v) A garland drain is provided around the quarry to collect the surface run-off. This also prevents

storm water to enter in to the quarry area.

(vi) Blasting operation is carried out between 12.30 PM to 3.00 PM.

(vii) Regular maintenance of HEMMs, CHP, and other equipments

viii Use of HEMMs with sound proof cabin.

(ix) Providing green belt around noise generating centers.
