Road Metal Mining Plan Lessee: Smt. D. PADMA LATHA (1.04Ac}

PART- B PROGRSSIVE MINE CLOSURE PLAN

1.0 ENVIRONMENTAL BASE LINE INFORMATION

i)Existing Land Use PatternThe lease applied area is located on a small hill. Lease area is barren with sparse

vegetation like shrubs & bushes. The hill is surrounded by agricultural lands are

available.

The local plantation in the surrounding areas of mine is limited to domestic trees

like Neem and Eucalyptus. The lease applied area contains very less quantity of

top soil.

ii) Water RegimeThe lease applied area operations extend up to ground level. The water that is

due to rains settles below the mine area. In most of the cases the quarries do

not operate during rainy seasons. This is due to accumulation of water and not

good for Safety.

iii) Human SettlementsThe nearest village Mydavolu is situated 1.3 km due West of the lease applied

area. Living population of this village is around 4650 (as per 2011 Census).

Agriculture and cattle rearing are important professions of the people living in

the village besides involving themselves in quarrying activity.

iv) Public Buildings, Places & MonumentsNo public buildings, important places and monuments a.l"P'-<:P

Regulation 1961.

v) Sanctuaries and eco-sensitive areasNo Sanctuaries and eco-sensitive areas are seen i

area.

vi) Flora and FaunaThe whole area is occupied by scattered sparse vegetation of thorny trees and

small bushes.

2.0 Environmental Impact Assessment

(a) Landscape changesDuring the next 5 years 1.04 Ac.of the quarry lease applied area will be reduced

by Sm. The applied area quarrying will alter the shape of the land with a large

sliced pit.

(b) - Air Quality in Environment

Air quality will not be disturbed in the lease applied area, as quarrying is very limited. Highest air pollution due to dust is caused during drilling, excavation, loading operations and during transportation. The dust is not siliceous, and is not harmful. The noxious gases will generate due to diesel based vehicles.

However as a precautionary measure the workers of the quarry wear a protective nose mask. The only silver lining in this pollutant's quality is that this ·does not contain respirable size of dust as defined under Mines Act-1952. That isthe reason that there are no cases of any lung diseases to the persons working.

AIR QUALITY

Base Level Allowable Level

SPM = 140µg/m3 360µg/m3

RSPM = 60µg/m3 120µg/m3

SO2 = 40µg/m3 80µg/m3

NO2 = 40µg/m3 80µg/m3

co= 1.0µg/m3 5.0µg/m3

Air quality is good but at quarries it is filled with dust, due to drilling, loading, haulage on the road, etc., But it will be within the permissible limits by adopting the following:

• The dust rising due to drilling will be controlled by c�ov�e=· �;;.__: cloth; 0,rector of"-·

• Dust suppression on haul road with sprin � of wate �t. chemical:Q •"'"'), (!.l\, additives. c:,q, ,i,�:��'- \ �· \�

_ Igneous in origin. This is the reason why the water does not percolate directly into the earth. Rather it tries to travel through the cleave planes or the joints. The site specific reason for low water pollution is that, the floor exposed is impervious whereas the direction perpendicular to the floor is pervious. Thus there will not be any direct contamination.

No water course is passing through the lease applied area. No adverse effect is anticipated on the water regime in the area due to quarrying of Road Metal & Gravel. The standards for water quality is given below.

(e) Vibration Levels

It is proposed to use low explosives and less quantity to minimize the effects so

that the vibration generated will be feeble within 8 Hz.

(f) Water Regime

The lease applied area is on hillock. The usable Road Metal quarry operations

extend up to ground level. The water that is due to rains settles below the

quarry. In most of the cases the quarries do not operate during rainy seasons.

This is due to accumulation of water. The rain water will be pumped out to the

nearby seasonal stream or will be used for dust suppression in the quarry.

(g) Acid Mine Drainage

Not Applicable

(h) Surface subsidence

Not Applicable

(i) Socio Economic Environment

The main occupation of villagers is agriculture, working in quarries and sheep

raring. The commencement of quarrying activity in this area improved the socio

economic status of the local people by creation of employment and paying taxes

to gram panchayat.

(j) Occupation Health and Safety

The lease applied area does not involve any hazardous methods. The quarrying

is simple and open cast mining method. In this, the possibilities of small injuries

are anticipated. The lessee is providing First Aid facilities at quarry site and

temporary Office room.

• Helmets once in three years as needed under Mi

(k) Historical Monuments

No historical monuments are located in and around the lease applied area.
