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
Pre-Feasibility Report
Building Stone – Laterite Quarry – HARISHA Page 11
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.
Pre-Feasibility Report

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.
