2.0 Introduction

2.1 General:

Building Stone - Laterite is one of the major materials being used in infrastructural

projects, mainly as an aggregate in concreting. In addition it also finds its applications

in stone masonry constructions, as railway ballast, filler material, water treatment

plants as filter media etc. etc.

Depending on the size of the material, Building Stone - Laterites are being classified

as size stones, coarse aggregate, fine aggregate etc. Even the fine powder, which is the

resultant of crushing of Building Stone - Laterite, finds its usage as finishing coat for

black top roads.

2.2 Present Proposal:

Considering the abundantly available Building Stone - Laterite source and the

growing demand in the market Sri. Harisha, has applied for operating a Building

Stone - Laterite – Laterite Quarry in Revenue land in an area of 1-00 Acre area,

Kannada District, Karnataka. It is proposed to produce an annual production rate

of 18020 Tons/annum (Avg.) with latest and state-of-the-art quarrying facilities.

2.3 Promoter’s Background:

The Building Stone - Laterite Quarrying project will be operated by the Sri. Harisha

who is an experienced entrepreneur from Dakshina Kannada District of Karnataka

State. He is an expert having immense experience, in the fields of Building Stone -

Laterite quarrying and allied business.



3.0 Project Description

3.1 General

Quarrying of Building Stone - Laterite is not very cumbersome unlike other stone

materials. Generally, with simple machines, it can be excavated and can be crushed to

required size and specification, at specialized stone crushers. In some cases, even the

sized stones are cut to the required size, for usage in stone masonry works.

The actual block splitting from the sheet rocks or boulders is mainly done manually or

in some cases by semi- mechanized methods, whereas the other operations such as

removal of overburden, lifting and transporting of cut blocks, etc. are carried out by

mechanized method. The various activities involved in Building Stone - Laterite

quarrying are briefed below:

3.2 Method of Quarrying

The proposed method of quarrying to be practiced at the Building Stone - Laterite

quarry is of "OPEN CAST" method by semi-mechanized way. However, care has to

be taken to make it environmental friendly by constantly adopting suitable mining

techniques. The quarrying will be carried-out by deploying machineries like

Excavators, Air compressors, Jack hammers, tippers etc. The mining techniques being

6.0 Proposed Infrastructure

6.1 General

To carry-out quarrying of Building Stone - Laterite various infrastructural facilities are

required for the main activity as well as for environmental protection & pollution

prevention. The basic infrastructural facilities that are required for the proposed quantity of

quarrying are described below.

6.2 Site Services:

Statutory buildings like office building, rest shelters, first aid room, etc. shall be

constructed in a semi-permanent construction using brick walls and tin sheet roofing.

Drinking water is being provided in well-maintained tank near to the rest shelter. In

addition, there will be proper sanitation facilities, including a septic tank with soak pit, for

the discharge of the sewage from the toilets.

6.3 Facilities for Environmental Management

Generally Building Stone - Laterite quarrying is expected to cause air pollution leading to

breathing problems. Activities like drilling, blasting, excavation and movement of heavy

vehicles generate dust and aggravate air pollution in addition to noise pollution. For

mitigating the adverse impacts of the above, suitable control measures are planned, which

are more detailed in the enclosed Environmental Management Plan.

For activities like drilling, dust suppression etc. water will be required. Also, for meeting

the drinking and sanitary needs of the employees/ workers, water will be required. For the

disposal of the sanitary wastewater (sewage), septic tank with soak pit is constructed at a

suitable place, within close vicinity of the proposed area.

To take care of the occupational health and safety of workers at site, engaged at strategic

locations/dust generation points like loading and unloading points dust masks would be

provided. Dust masks would prevent inhalation of Respirable



Particulate Matter (RPM) thereby reducing the risk of lung diseases and other respiratory

disorders. Regular health monitoring of workers will be carried out.

The solid waste that is likely to be generated from the proposed activity will be mainly from

the excavation process. This will be in the form of flakes, of irregular shape. This will be

collected and broken into pieces and can be sold as aggregates for civil works, because of its

hard nature.

Most of the area is of sheet rock and the present proposed working is confined to sheet rocks.

Less than 4% of materials are being treated as waste in this area. The rejected waste material is

stacked in the Waste Dump as shown in the Mining Plan. A JCB will be used to remove the

over burden from the surface. When the dump reaches optimum height, suitable greenery will

be grown on this dump to stabilize them.

In addition, as a proactive measure, the following activities will be initiated:

The rainwater accumulating in the work area will be collected and will be drained-out

to the downstream properly with guide drains so that it can be used by the downstream

fields for their agriculture and allied purposes.

To avoid soil erosion, rain water entering into the mine pit, carryover of the material

with rain water, suitable garland drains will be provided all along the active mine area.



7.0 Rehabilitation & Resettlement (R & R) Plan

7.1 General

The proposed Building Stone - Laterite quarrying area is located near Badaga Yekkar

Village of Mangalore Taluk & Dakshina Kannada District of Karnataka State. The

proposed site is at about 1.3 Kms from the nearest human habitation i.e. Kondemula &

Badaga Yekkar village. In the core area, there are no houses/ hutments etc. Hence the R &

R Plan for the proposed quarry site is limited to the environmental protection and other

social measures planned as part of the proposed activity.

7.2 Human Settlements

There is no human settlement in the core zone

7.3 Socio-Economic Benefits

Spurt in industrialization and mining activities have invariably brought a drastic change in

the environment including the society connected with region. Mostly remote areas,

urbanization and influence of modern civilization fall within the limits of mine

development.

A natural corollary to this the socio economic aspects of the local inhabitants who have

dwelling this region for generations, get suddenly and probably a radical change,

consequent to their abrupt exposure to the mining.

The local people will get employment opportunities better medical and educational

facilities etc., mainly due to the mining operation from this project. In addition to this the

literacy rate and better living standards shall increase due to the enhanced earning capacity

of villagers.

7.4 Storage and Preservation of Topsoil

There is no soil cover occurring, as the area is exposed with Building Stone - Laterite.

Whenever the topsoil generated, shall be collected and stacked separately for use in

afforestation and road works.



7.5 Reclamation of land

Land restoration or reclamation of the area is very essential in any mining industry. Proper

measures adopted during restoration will control most of the adverse environmental

impacts of mining and also improve the aesthetic beauty of the area. Due to the Mining

activities in this area, the profile of the ground will change due to formation of pits. At the

end of the mining operations, all solid wastes generated will be used in back filling of

quarry pits in order to bring back original contour of the terrain as for as possible. The

separately stacked top soil will be used to spread over on the compacted back filled area in

order to facilitate the re-vegetation process, which in turn controls silt flow towards the

downstream.

7.6 Environmental Aspects:

The environmental aspects associated with the proposed activity along with the suggested

mitigation/ control measures are more clearly elaborated in the Environmental Management

Plan.

7.7 Implementation of EMP & Monitoring Programme

The environmental management plan is detailed on the basis of impact assessment. Control

and mitigation measures for the adverse impacts envisaged.

As the major environmental attributes have been confined to the project area alone,

Implementations of the proposed control measures and monitoring thereof will be

undertaken on the regional basis. The Quarry will ensure the implementation of the

measures within the mine area and carryout efficient monitoring.

In order to implement the measures suggested for mitigating the adverse impacts on the

environment, it is suggested to monitor the environmental parameters regularly.



8.0 Project Schedule & Cost Estimates
