Summary on Environmental Impact Assessment

Production of Barytes mineral in India makes our country Number 3 in ranking. The

metallurgical and mineral industries constitute the bedrock of industrial development as

they provide the basic raw material for most of the industries World production has

increased from 6.0- 6.5Mtpa in the early 2000s to 7.7Mt in 2004 and has increased

sharply since to an estimated 8.3Mt in 2006. India’s contribution in its production lies at

1.2Mt during 2006. Barytes (or barite) is the naturally occurring mineral form of barium

sulphate. Its main properties are its high specific gravity (4.5), very low solubility; it is

non-toxic, and also chemically and physically un-reactive.

More than 80% of the mineral production is from open cast mines and therefore, it

becomes necessary to focus on the overburden quantity along with mineral production in

order to assess the total amount of annual excavation in India’s mining sector. Barytes

ore is the source of primary “BaSO4” for the Paints and Chemical Industries.

Sri Kanaka Durga Tribal Labour Contract Mutually Aided Cooperative Society proposes

to produce Barytes and Dolomite over a land extent of 58.704 Ha. situated in Survey No.

58 of Pocharam village under Garla Mandal in Khammam district, Andhra Pradesh.

A Mining Plan was prepared and submitted, which was duly approved by ‘The Director

of Mines and Geology, Hyderabad’ under Rule 22 (4) of MCR, 1960 in the applicant’s

name as Mr. Palthya Moni, resident of Ratistambam Bazar, Garla Village, Khammam

District, Andhra Pradesh. The mining lease is approved for 58.704 Ha. (145 Ac.) area and

this mining lease approval is valid for a period of 20 years.

In order to fulfill the further necessary requirements for obtaining the Environmental

Clearance for this mining activity, the proponent has carried required Rapid

Environmental Impact Assessment (REIA) study in and around the proposed mine lease

area. This assessment is performed to identify the likely environmental impacts and based

on the findings; an effective environmental management plan will be put in place as per

the EIA Notification 2006 general guidelines and the revised Model TORs outlined for

Mining projects.

The standards set by the Central Pollution Control Board (CPCB) and the State Pollution

Control Board (SPCB) will be met and adhered to.

This study covers an area surrounding the project site with a radial distance of 10 km

from the proposed mining lease area. The baseline monitoring was carried out during the

Summer Season ’09 (period from March to May ’09).

PROJECT LOCATION:

The proposed M/s. Sri Kanaka Durga Tribal Labour Contract Mutually Aided

Cooperative Society is situated in Survey No. 58 of Pocharam village under Garla

Mandal in Khammam district, Andhra Pradesh.

SCOPE OF THE PRESENT STUDY OF REIA :

The study area covers an area of 10 km radius around the proposed project site. The study

includes detailed characterization of various Environmental components such as Air,

Water, noise, Land and Socio-economics with in the study area.

Objectivies of study are

• To assess the existing base line data of Air, Water, Noise, Land and Socio-

economic environment.

• To evaluate the beneficial and adverse impacts of the proposed activity.

• To prepare an Environmental Management plan (EMP) detailing control

technologies and measures to be adopted for minimizing the impacts and

improving the Environmental Quality.

• To predict the incremental levels of pollutants in the study area due to the

proposed project.

• To prepare post project programme for monitoring and regulating Environmental

parameters.

ENVIRONMENTAL SETTINGS:

Meteorological Studies:

Meteorological stations are installed at site to measure the wind speed, wind direction,

temperature and humidity.

Air Environment:

To know the exiting ambient air quality, nine sampling stations with in the study zone are

identified and monitored for pollutants like, suspended particulate matter (SPM), RSPM,

SO2, NOx and CO. For this sampling calibrated high volume air samplers and respirable

dust samplers were used.

The Ambient air quality measured at nine sampling stations with in the study zone

showed the following maximum and minimum concentrations of the pollutants –

S. No. PARAMETER MIN (µg/m3) MAX (µg/m3)

1. SPM 71 128

2. RSPM 24.5 45.8

3. SO2 6.8 12.15

4. NOx 5.14 11.18

5. CO 0.039 (ppm) 0.0498 (ppm)

It may be seen that all the parameters i.e., SPM, RSPM, SO2, NOx and CO are well with

in the range of 24 hr average of National Ambient Air Quality Standards.

Noise Pollution :

The Ambient noise levels monitored with in the study zone show an minimum and

maximum values of 52 – 63.9 dB(A) with Night equivalent values in the range between

39.8 - 45 dB(A).

Water Environment:

Six numbers of water samples (Ground & surface) were collected in the study zone, i.e.,

one sample from surface and five samples from bore wells. All these samples are free

from colour and pollutants. The test results show that all parameters well with in the

permissible limits of drinking water standards.

Land Environment:

Four soil samples were collected and analysed to know the physical and chemical

properties.

Land use:

In the study zone predominantly two crops are under cultivation i.e. paddy and Sugar

cane. The region is predominantly rural and suburban. Total population in this study zone

are less than one lack.

FLORA & FAUNA:

The area is plain and there is no forest around the study area. As the area is agriculture

oriented there is no suitable habitat for any wild life.

SOCIO – ECONOMIC ENVIRONMENT:

The operation of the proposed project could result in elevation of the economic status of

the people surrounding. Proposed project could result in creation of employment which

result in improvement of economic status of the people surrounding. The Management of

M/s. M/s. Sri Kanaka Durga Tribal Labour Contract Mutually Aided Cooperative

Society, has proposed to give preference to local people for recuirtment of personal for

project operation. There fore the impact on socio-economic Environment could be

beneficial.

PROCESS DESCRIPTION:

MINING OPERATION

The mining will be carried out by manual open cast method with the help of jackhammer

drilling and blasting in this area. Based on present demand and the mineral reservesavailable in the area, it is proposed to rise about 2500 T of Barytes per year on an average

from this area. It is expected that the mine will be operated fro 300 days in a year. During

this plan period, the Barytes production will be obtained by excavating one bench of 4.0

m height from the surface of the area by advancing the old pit (OP-1) towards south. To

obtain the full thickness of the Barytes, the host rock (Cherty Dolomite) has to be

removed along with the mineral. The year wise workings are shown on plan and sections

of plate – 4 and the production particulars are given below:

CONCEPTUAL MINING

i) Exploration: In this lease period it is proposed to dig two trenches, four trial

pits and to drill three DTH holes to know the extent of mineral body i.e., Barytes

and Dolomite respectively along with strike & dip directions.

ii) Exploration: The mining will be carried out by open cast method in this area

with the help of jackhammer drilling and blasting and about 5000 tones of Barytes

will be produced per year from this area. The existing pits will be developed

along the strike and dip direction of Barytes over an extent of 24000 m2 in this

lease and about 16400 m2

of the pits area will be reclamated at the end of themining.

iii) Waste management: During this lease period, about 10718 m3 of waste will

generate and this waste will be used for reclamation of the pits over an extent of

16400 m2.

iv) Plantation: In this lease period about 7200 m2 (1200 X 6m) buffer zone will

be planted around the area.

v) Utilization of the area at the end of mining: At the end of the life of the

mine, the Barytes pit will be reclamated and balance pit will be used for rain

water harvesting.

OPEN CAST MINING

i) Mode of workings: The mining will be operated by manual, open cast

method with the help of drilling and blasting. The minerals will be excavated by

forming 2.5 m height benches from surface. For drilling purpose two

jackhammers and a tractor mount compressor is used. Apart from this no

mechanization is required to mine in this area.

ii) Layout of mine working: For the first two years, the Barytes production will

be obtained by excavating two beches of 2.5 m height from southern face of old

pit OP-1 and in balance period the workings will be advanced towards south and

towards north in strike directions as shown plate – 4.

As per Dolomite is concerned, production will be obtained by excavating 1.5 m bench

from southern face towards north.

PRODUCTION OF BARYTES

It is proposed to mine Barytes from first year onwards on south side of pit OP-1 and later

these workings will be advanced towards south and north i.e., along the strike direction

for first five years production (as per plate-4). Since Barytes is associated with Cherty

Dolomite, it is proposed to do mining from both materials together and later the mineral

(Barytes) & waste (Cherty Dolomite) will be separated by manual hand picking.

During the first year, the Barytes production will be obtained by excavating two bench of

2.0 m each on southern side of lod pit OP-1, over a length of 30 m, to a width of 25m and

to a height of 4 m between the RLS of 105-100 and obtained about 5000 tonnes of

Barytes and 3000 cu.m of Cherty Dolomite in the first year.

6



During second year, the two southern side benches of first year wormings will be

advanced towards south to a distance of 30 m and to a width of 25 m and obtained about

7000 tonnes of Barytes and 7000 cu.m of Cherty Dolomite (waste).

During third year, the two southern side benches of second year workings will be

advanced towards south to a distance of 30 m and to a width of 25 m and obtained about

5000 tonnes of Barytes and 7000 cu.m of Cherty Dolomite (waste).

Fourth year, towards northern side two benches of 2.0 m will be advanced towards north

to a distance of 30 m and to a width of 25 m and obtained about 5000 tonnes of Barytes

and 7000 cu.m of Cherty Dolomite (waste).

Fifth year, the Barytes production of 7000 tonnes and the Dolomite waste about 7000

cu.m will be obtained by advancing the two southern benches of fourth year towards

north to a distance of 30 m and to a width of 25 m as shown in plan -4.

PRODUCTION OF DOLOMITE

It is proposed to mine Dolomite (Low silica) situated on West side of the area from south

towards north from 2nd year onwards with 7000 tonnes annually from the grant of lease.

MINE DRAINAGE:

1. Water table: Normally the ground water table is available at a depth of more than

60 m in rainy seasons and 80 m depth in summer from the bore wells that are

available in this region from normal ground level.

2. Encounter and discharge of mine water: There is no chance of groundwater

likely to be encountered in the mine. But the rainwater will accumulate at pit

bottom in rainy seasons and this rain water will be dried up slowly by percolating

through the joins of the base rock.

STACKING OF MINERALS REJECTS AND DISPOSAL OF WASTE

a) Nature of Top Soil/Waste and Mineral Rejects: The proposed mine workings does

not consisting of soil & screen. So there is no separate top soil generation.

7



Dumping site: The overburden/side burden will be stacked adjacent to the working on

southern side of the area over a length of 150 m width of 32 m and to height of 6 m,

where the dump location is shown in plate -4.

b) Configuration & sequence of Build of Dumps: The waste will be stacked adjacent

workings temporarily on southern sided of the area and the waste will be used for

reclamation of the pit from second five years on words. In this plan period, the dumps

will be stabilized by keeping the dump slopes at 450 angle and by constructing retailing

wall on dump slopes. The proposed dump location is shown on plat -4.

ENVIRONMENT MANAGEMENT PLAN

8



Post Construction Phase

Air Pollution Management

The proposed mining activity would result in the increase of SPM concentrations due to

fugitive dust. Frequent water sprinkling in the vicinity would be undertaken and will be

continued as there is possibility for dust generation due to truck mobility. It will be

ensured that both gasoline and diesel powered vehicles are properly maintained to

comply with exhaust emission requirements.

Dust emissions and particulate emissions will be controlled by water spraying through

sprinklers at all the sources of dust formation and corresponding mitigative measures are

elaborated as follows:

Regular water sprinkling at dust emanating sources viz., drilling and

transportation through haulage roads, etc will be carried out.

Periodic maintenance of transport vehicles and equipment will be carried out to

check emission levels.

Overloading of trucks will be avoided and carrying the ore/mineral in covered

trucks will be taken-up to minimize pollution levels.

Greenbelt will be developed that will act as a pollution sink.

WATER POLLUTION MANAGEMENT

Generally water environment would have adverse effects due to mine discharges and

siltation due to storm water. As this is an open cast mining method it will not

generate any wastewater as there is no mineral processing involved. The mining of

dolomite and barytes does not involve any treatment or beneficiation by using water,

expect chipping and sizing to required size. Therefore, the question of disposal of

water will not arise. Moreover, mining activity much above the ground water level

doesn’t lead to any ground water contamination.

POST PROJECT MONITORING PROGRAMME

9



In order to maintain the environmental quality within the standards, regular monitoring of

various environmental components is necessary. The proponent will allocate Rs. 5.0

lakhs annual budget towards environmental protection initiatives.

ENVIRONMENTAL MONITORING

Regular monitoring of various environmental parameters shall be carried out to ascertain

the following points,

Status of air, noise, water, land pollution within the plant and in its vicinity;

Generate data for predictive or corrective purpose in respect of pollution; and

To assess and monitor environmental impacts periodically.

SAFETY AND ENVIRONMENT

• The management firmly believes in the concept of safety and

environmentally sustainable growth. The authorities and staff are very much

concern in Environment issues.

• The management is going to develop scientifically designed green belt around the

premises to mitigate air and noise pollution impacts on the surroundings.

• The management proposed to monitor ambient air as per APPCB guidelines.

• All the employees are provided with personal protective equipment such as

helmets, hand gloves, safety shoes, goggles and apron as per their place of work.

• The management will provide safety training to all employees periodically and

regularly.

CONCLUSION
