The present mine lease forms a cluster of 2 mines with a total mine lease area of

19.083 ha.

11.3 Proposed Method of Mining

Fully mechanized opencast method by developing benches with a height of 6 m in 2

phases of 3m each is proposed, wherein wire saw cutting is adopted to cut the

granite, while blasting is proposed to construct the haulage road and remove over

burden. The separation of blocks from the mother rock will be carried out by

drilling, wedge cutting, blasting, excavation will be done by the machinery.

Transportation will be made by trucks to dispatching points.



11.3.1 Development and Production

It is proposed to initiate mining in the first year from the top most bench of 224

MRL, during second year mining is initiated from the top most bench of 214 MRL,

during third year mining is initiated from the top most bench of 210 MRL, during

fourth year mining is initiated from the top most bench of 205 MRL, during fifth year

mining is initiated from the top most bench of 200 MRL. Total excavation planned is

150000m3/year from which 60000 m3/year of colour granite is recovered. The waste

to be handled during this year is 90000 m3/ year.

11.4 Conceptual Plan

The mining operations will follow Fully mechanized open cast method. The entire

reserves estimated under proved, probable and possible categories are exploitable

except mineral blocked in 7.5 m buffer zone all along lease boundary as per statutory

requirement. The total reserves estimated are 2884090 m3 based on the mine scheme.

Therefore, the targeted capacity of 150000 m3/annum (Colour granite - recovery @

40% - 60000 m3/annum and waste @ 60% - 90000 m3/annum) and the anticipated life

of the mine is considered as 19 years for recovery of colour granite.

11.5 Employment Potential

The manpower requirement is 33 for various skilled, semi-skilled and unskilled jobs

headed by a mine’s manager.

11.6 Site Services

The Site services provided are temporary office, rest rooms, first aid room, blasting

shelters, water for drinking in the mine lease area. Temporary sheds with cement

plastered brick walls and G.I. sheet or grass roofing are constructed for site services.

The workers required shall be sourced from surrounding villages. Drinking water is

obtained from nearby villages through tankers to mining staff and workers. A

tractor mounted tanker is provided for sprinkling of water mainly on village roads

to suppress the dust generated due to vehicular movement. Fencing is also

provided around working area to avoid accidental slippage of men and animals,

while worked out areas are used as reservoir for storage of rain water.



11.7 Water Requirement and Effluent Generation

The total water requirement is 16.6 KLD. Water requirement for the proposed

activity is mainly for maintaining the green belt (3.6 KLD), for sprinkling on the haul

roads (2.3 KLD) to mitigate dust emissions, occasional wet drilling (9.2 KLD) and for

domestic purposes (1.5 KLD). Stagnated water in worked out area is used for

sprinkling, wet drilling and green belt development. The domestic water will be

drawn from Sibilipeddavalasa village. The generation of wastewater is from

domestic source only; it is expected to be approximately 1.2 KLD, which is sent to

septic tank followed by soak pit. The daily water requirement for the cluster of mine

operations would be approximately 27.2 KLD comprising of requirement for water

sprinkling on mine haulage roads etc. It is proposed 4.6 KLD of water is used for

water sprinkling for common Road.

11.8 Baseline Environmental Status

The baseline data for ambient air quality, surface and ground water quality, noise,

and soil quality was collected and analyzed for various parameters to determine the

existing quality and flora and fauna study of the impact area was conducted during

period of March – May 2019. The ambient air quality monitoring results shows that

the values are within the prescribed limits of national ambient air quality standards.

Ground water sample analysis results show that the values are above the limits for

total dissolved solids, total hardness, most of the locations compared to Indian

Standard Drinking Water Specification of IS: 10500-2012. Noise quality parameters in

the study area are within prescribed limits of Ambient Noise Standards. There are

no schedule I flora or fauna within the impact area.

11.8.1 Identification and Quantification of Impacts

The project activities that are likely to cause potential impacts on environment are

mining operations, transport and associated infrastructure. Mining operations

involve development of benches, haul roads, drilling, blasting, wire saw cutting,

excavation, handling and transportation of mineral and waste materials. The likely

effects of these activities are land degradation, fugitive dust generation, noise and

vibration levels, increased run-off during monsoon and human health risks. There



is one more mine adjacent to this lease area with an area of 9.951 ha. The cumulative

impacts due to the cluster are also assessed in addition to the impacts due to this

project.

ISCST3 model was used for air quality impact predictions. The predicted maximum

24 hourly GLC’s for the cluster were used to predict the ground level concentrations,

and the maximum predicted values of PM, PM10 and PM2.5 are 0.47, 0.03 and 0.02

g/m3 respectively and the maximum values are observed at center of mining area

for the cluster including Tandra exports. The cumulative values (baseline and

predicted) are found to be within the prescribed standards of national ambient air

quality.

11.9 Environment Management Plan

The management plan is drawn in consultation with the project proponent, mining

engineer and geologist after evaluating various methods for mitigation and control

of pollution. The environment management plan is drawn to address the impacts

monitored, identified and predicted for the present project and the cluster in which

the present project falls in. The environment management plan addresses the

impacts identified.

11.9.1 Dust Emissions

Dust will be generated during mining, drilling and also during handling and

transportation of the material. Haulage of minerals within lease area will lead to

emissions of fugitive dust in the mining area. It is proposed to provide water

sprinkling in haul roads to reduce the fugitive dust emissions. Tractor mounted

sprinkler will be deployed. Dust generated during occasional drilling and blasting

will be suppressed by covering the drill rods by wet gunny cloth.

11.9.2 Noise Pollution Control

Major noise sources during operation are mine machineries, equipment, occasional

drilling and blasting and vehicular movement. The following measures will be

adopted to reduce noise levels; improved silencers, mufflers and closed noise

generating parts, regular and periodic maintenance of noise generating machinery



including transport vehicles, location of site office and other infrastructures away

from the noise sources. Personal protective equipment like earmuffs, earplugs.

Canal caps will be provided to workers involved in work closer to noise generating

sources. The exposure to noise levels is also mitigated by adopting employee

rotation.

11.9.3 Water Resources and Waste Water Generation

The daily water requirement for the mine operations would be approximately 16.6

KLD comprising of requirement for water sprinkling on mine haulage roads etc.

The other major impact anticipated from mining activity is erosion and

sedimentation, as large area of land is exposed to erosion. The area exposed due to

mining shall be 9.132 ha in this project. It is proposed to provide garland drains

with rip rap at the discharge point to avoid sediment joining streams outside the ML

area. The daily water requirement for the cluster of mine operations would be

approximately 33.2 KLD comprising of requirement for water sprinkling on mine

haulage roads etc. it is proposed to use 4.6 KLD of water for water sprinkling for

common road.

11.9.4 Land Management

Land degradation is one of the major adverse impacts of opencast mining in the

form of excavated voids and also in the form of waste dump of 1.3 ha. During plan

period about 6.872 ha area will be occupied by pit, and plantation will cover 0.075 ha

and roads cover an area of 0.03 ha. Other temporary constructions are dismantled

after completion of mine workings.

11.9.6 Socio-Economic Environment

There are no settlements in the ML area. Hence no rehabilitation and resettlement

(R&R) is required. The mining activity will improve the economic status of the

people surrounding the mine lease area. The proposed project generates

employment to 33 people, and all the semiskilled and unskilled jobs will be provided

to the local villagers. Apart from employment, the state government and village

panchayath will get royalty due to mining.



11.9.7 Green Belt

Greenbelt is proposed as an additional mitigation measure for dust control in

addition to water sprinkling. It is proposed to have dense green belt in and around

the mine site, loading and unloading facilities, and in abandoned mine area during

reclamation process. About 0.075 ha (115 trees) area will be planted during lease

grant year and 600 tress along connecting road. Precautionary measures like regular

watering, providing manure and fencing will be taken up to achieve 90% of survival

rate of plantation.

11.9.8 Transportation

The required truck trips for transporting the mineral from this mine lease shall be in

the order of 50/day. The surrounding area is forming a cluster of mines producing

granite and total number of truck trips generated due to the cluster is 100/day.

Currently the Mine lease area is connected to Duggeru – Makkuva by a cart truck

road. The Duggeru – Makkuva road is a 2-lane road and hence, the dispatch of

trucks shall be staggered in consultation with neighboring mine lease proponents to

avoid traffic congestion.

11.9.9 Occupational Health and Safety Measures

Protective equipment will be provided to the employees such as safety shoes,

helmets and dust masks. Dust masks would be provided for the safety of workers at

site, engaged at dust generation points like drills, loading and unloading points, etc.

Dust masks would prevent inhalation of particulate matter thereby reducing the risk

of lung diseases and other respiratory disorders. Regular health monitoring of

workers will be carried out. The health impact due to dust shall be addressed by

rotation of employees from dust generating jobs after periodic health monitoring.

11.10 Environmental Monitoring Program

The monitoring program consists of collection and analysis of air, soil, noise and

surface and ground water samples. Environmental monitoring shall be conducted

on quarterly basis to assess the pollution level in the ML area and in the surrounding

areas as well. An Environment Management cell shall be established to look after



all the environment related activities. This cell will be headed by the Mines Manger.

The cell is responsible for all the environmental management activities including

environmental monitoring, greenbelt development and to ensure statutory

compliance with the regulatory authorities. The total capital expenditure envisaged

for environmental monitoring is Rs.1.59 lakhs. The total capital expenditure

envisaged for cluster environmental monitoring is Rs.7.44 lakhs.

11.11 Environment management Plan

The management measures mentioned in the previous paragraphs with respect to

air, noise and vibration, water, solid waste, occupational health and greenbelt are

generically, applicable to both the mine leases in the cluster. Additionally, the

following measures shall be adopted to mitigate the cumulative impacts;

Strengthening of common haulage roads, mining activity during day time to reduce

noise and vibration impact, blasting activity to be conducted at designated times

decided on mutual consultation, mineral dispatch on mutual consultation to avoid

traffic congestion, pooling of CER fund to avoid duplication of CER activity,

adoption of water conservation measures and water harvesting measures in

common properties of the surrounding villages after mutual consultation to

compensate the water usage from common properties, plantation along connecting

roads, drainage management and planning to avoid the sediment load and to avoid

over flow of storm water into the connecting drains, mutual support in case of any

emergency. The total capital expenditure envisaged for environmental management

is Rs.8.78 lakhs with annual recurring expenditure of 5.18 lakhs. The total capital

expenditure envisaged for cluster environmental management is Rs.7.44 lakhs with

annual recurring expenditure of 14.62 lakhs.

11.12 Corporate Environment Responsibility (CER)

It is proposed to spend Rs. 1.5 Lakhs in seven years for CER activities like provision

of drinking water facility, solar street lamps, trees plantation. The management will

provide training and awareness on job facilities to unemployed graduates and post

graduates, embroidery and tailoring training to backward and weaker section

women and training to local sports persons.



11.13 Mine Closure Plan

The disturbed land including area disturbed due to excavation, dumping,

construction of haul roads, ramps, structures would be reclaimed before finally

abandoning the mine. Thus, the area shall be fully reclaimed during last five years

of life of the mine. During post mining period all the disturbed areas will be

reclaimed before decommissioning / abandoning the mine. The closure involves

the; back filling the over and side burden, fencing around the pit and greenery

development. The top bench shall be afforested with local grass and plants.

11.14 Conclusion

The environmental impact study identified various mining activities that may result

in change in baseline status, and accordingly the proposed mitigation measures

mentioned in mine plan and the environment management plan were observed to be

sufficient to ensure least impact on the surrounding areas. The residual impact due

to mining is mainly loss of habitat which has to be compensated, loss of biodiversity

which can be offset, and worked out mine pit which has to be reclaimed. The

management assures to adopt extensive plantation in surrounding areas to

compensate habitat and biodiversity loss, thereby reducing the impact to the

maximum extent, while taking responsibility for implementing an effective mine

closure plan.
