2.0 INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION 2.1 Identification of Project and Project Proponent

Sri K. Palani Swamy is a private individual. He is in granite business for the last 15 years. The proposed Colour Granite mine is located in Sy. No. 53/2 of Budibanda Village, Ravikamatham Mandal, Visakhapatnam District, Andhra Pradesh.

The owner has contacted the buyers at Visakhapatnam, Chennai and other important trade centers to export Colour granite from this area. At present Italy, Japan, Germany, China and U.S.A are the major importing countries of Granite. Granite has got good demand in the domestic and international market. Granite is being marketed since 15 years and we can expect good market demand will continue for years to come with improved technology. So there will be increased demand in local and international market for the Colour Granite in the years to come.

2.2 Brief Information about the Project

The mining lease area of 1.0 Ha. open cast semi mechanised mining will be followed and it has been proposed to produce approximately 2460 m3/annum of Colour Granite. The nearest habitation Krishnabhualapurm Village is at 1.0 Km due NW from lease area.

2.3 Need for the Project and Its Importance to the Country or Region

The demand for granite increased due to rapid industrialization and growth in infrastructure. So the number of granite producing quarries is increasing in India. Granite is the chief material for the export industries like monuments, flooring slabs, Kitchen articles, sculptures & export. Based on the demand of Granite, the lessee intends to produce the required quantity of Colour Granite for domestic market.

As per EIA notification 2006 the project falls under Category- B, the proponent is submitting the proposal to get Clearance for production capacity of 18,000 Cum/ Annum of granite blocks from DEAC, DEIAA, Andhra Pradesh for the purpose of grant of quarry lease. The demand and supply for the Colour granite is growing which makes a lot of scope for revenue generation. The granite is further processed and supplied to industries after quarrying.

India is amongst the leading exporter countries of stones in the world. The major importers of Indian stones are USA, China, UK, Italy, Belgium, Germany, UAE, Hong Kong, Spain, Taiwan, Netherlands, Canada, Turkey, France, Russia and CIS countries. The growth is continuing and the demand for marble, granite, sandstone and other dimensional stones and stone products is anticipated to grow at around 15% CAGR.

2.4 Employment Generation

Open cast semi mechanized mining method will be used. About total 27 workers are going to be engaged for at least 300 days in a year. It will provide indirect employment to several workers in the area. The occupation of the local inhabitants in surrounding villages of the mine area is Agriculture. The mining activity in this belt will benefit the locals both directly and indirectly. The directly beneficiaries will be those who get employed in the mines as skilled and unskilled workers. The indirect beneficiaries will be those who open small business to sell goods required by the residents whose “per capita” income will be enhanced by the mining activity, and thereby their purchasing power will be increased. In the long run a lot of social goods are expected in the comparatively backward area when the inhabitants will be able to send their children to school.

3.5.1 Regional Geology

The Eastern Ghat Mobile Belt is a high grade terrain along the east coast of India and bounded to the north by the singhbhum crator and to the west by bastar craton, the dharwar craton and Nellore – Khammam schist belt. Nanda and Pati (1989) and Ram Krishnan etc.al. (1988) on the basis of dominant lithological assemblages of Eastern ghat belt. Longitudinally divided into following four (4) zones.

1) Western Charnockite Zone 2) Western Khondalite Zone 3) Central Migmatite Zone 4) Eastern Khondalite Zone

Recent works by Cherty et.al 2001, 2003 helped in identifying leptynites and shear zone in Eastern ghat belt and there by sub divide the EGB to several structural domains viz.

A) Eastern Ghat Boundary Shear Zone B) Sileru Shear Zone C) Koraput – Sonpur Shear Zone D) Nagavalli – Vamshadhara Shear Zone

The area lies between Sileru shear zone in the west and Nagavalli – Vamshadhar Shear zone is identified as Eastern ghat provides with specific lithology, structure and metamorphic grade. The area from Salur in the North – Rajahmundry in the south including Aruku – Paderu in the west and Visakhapatnam – Vizianagaram

comes in Eastern ghat provides area with principle litho unit like Khondalite, Charnockites, leptynite and calc granulite

3.5.2 Local Geology

The Quarry Lease area comprises of massive sheet rock formation. The area forms part of the Archean Metamorphic belt of the Eastern Ghats occupied by Khondalite, Charnockite series of rocks and garnetiferous gneissic granites. The litho units may be classified as Archean complex subject to granulite facies of metamorphism with later quartzo-felspathic injections resulting in migmatisation. The rock types exposed in the mandal are as follows : Archeans - Quartz – Felspathic Gneiss/Granite Gneiss, Quartz-Feldspar-Biotite-

Garnet Gneiss Migmatite with inclusions of Charnockite, Pyroxene Granulite or Enclaves of Khondalite, Hypersthene Gneiss/Granite, Pyroxene Gneiss

The rock types exposed are mainly hypersthene gneisses and charnockite series of rocks from acidic to basic, migmatites, quartzo-felspathic granite gneiss. The rock is melanocratic in colour and equigranular with medium to coarse grain texture.

3.5.3 EXPLORATION As the colour granite deposit is forming a hill, raised 357 m above ground level within the quarry lease area. The cross sections were drawn perpendicular to the slope direction, the cross sectional area of the individual sections are calculated to arrive at sectional area multiplied by the appropriate sectional influence to arrive the volume of rock mass. A conservative recovery of 25% rough blocks is considered in estimation.

3.6 RESERVES

The deposit upto RL 395 m is considered as Proved Reserves. The geological reserves are given in Table - 3 below.

Marketing Area of Final Product/s, Mode of Transport of Raw Material and Finished Product

No raw material will be required in the proposed project. The operation involves the extraction of Colour Granite and it will be transported to the Local market through Lorry’s. The existing roads will be utilized for the transport of Colour Granite from mine site to market.

3.8.1 Use of Mineral

The rough blocks being quarries in the mines will be consumed in the local market & also will be exported. These blocks will be utilized as building material for the foundations in the major irrigation projects.

3.9 Resource Optimization / Recycling and Reuse Not envisaged. 3.10 Availability of Water Its Source, Energy / Power Requirement and Source 3.10.1 Water Requirement


10

Water is required only for drinking purposes, green belt development and dust suppression. The number of working people is around 27. So the total water requirement will be around 5 KLD. Source of water is bore wells.

3.10.2 Power

• Estimated Power: 180 KVA • Source: D.G. set of 180 KVA • Fuel consumption: 300 LPD

s 3.11 Quantity of wastes to be generated (liquid and solid) and scheme for their

management/ disposal

Solid Waste Generation& its Disposal

The granite occurs as surface deposit without soil cover and weathering is limited to the inter-spaces of boulders and joint planes. In this type of extraction the recovery factor is as medium as 25 %, so 75% comes out as waste. During the next Five years about 36,900 Cum of waste material will be generated. This waste will be stacked in the dump yard located in the SW side of the lease area covering an area of 3500 sq.m with a height of 12 m with 450 slope angle. A retaining wall will be constructed around the dump for preventing slanting of boulders.

3.11.1 Liquid Effluent

No liquid effluent will be generated at the mine site.

4.0 SITE ANALYSIS

5. PLANNING BRIEF 5.1 Planning Concept It is proposed to produce total of 3000 Cu.m. per Annum of Colour Granite from the

proposed mining lease. 5.2 Population projection The project will employ mostly workers from nearby villages. About 27 persons will be

employed as workers for this proposed mine. There will not be any increase in population due to the project.

5.3 Land use planning The project is located in 1.00 Hectares of Govt. land. There will be change in land use

as the Colour granite mine will be excavated. An extent of about 16,400 Sq. m area will be sliced down during next Five years to a depth of 35.0 m. from the surface of QL area.

5.4 Assessment of Infrastructure Demand (Physical & Social) On the basis of the preliminary site visit, the infrastructure demand in the villages was

assessed on the basis of need and priority.

5.5 Amenities/Facilities First aid box and drinking water facility will be available at the site. Rest shelter will be

provided at the site. It is proposed to provide the site services like Mines office and other statutory constructions like rest shelter, first aid, work shed and drinking water as required near the quarry lease. Drinking water will be supplied to the workers from the bore well opened in the adjacent quarry site & agricultural fields.

6. PROPOSED INFRASTRUCTURE 6.1 Residential Area (Non Processing Area)

As the local persons will be given employment, no residential area/housing is proposed within the mining lease area.


12

6.2 Water Management

The total water requirement is 5 KLD. There are no chances for changes in quality of surface water or ground water the quarry operations will be carried out on slopes of the rocky terrain. Hence neither the ground water table nor the general surface drainage pattern is affected. No water will be discharged from the quarry.

Following measures shall be taken:

• Garland drain with sedimentation pit will be constructed all along the working pit

and dump to arrest the silt. • It shall be ensured that silt discharged from the mine area will be minimized to

the utmost extent. • It shall be ensured that good quality potable water is provided for drinking

purposes. Good sanitation facilities (toilets with septic tank followed by soak pits) shall be provided and maintained for good hygienic conditions.

• The spillages form fuelling of machinery shall be avoided and in case of any spillage the same shall be handled properly. Likewise the spent lubricating oils etc. shall be safely collected and properly disposed off.

6.3 Sewerage System

Disposal into soak pit constructed. 6.4 Industrial Waste Management

Not applicable. 6.5 Solid Waste management

The granite occurs as surface deposit without soil cover and weathering is limited to the inter-spaces of boulders and joint planes. In this type of extraction the recovery factor is as medium as 25 % so 75% comes out as waste. During the next Five years about 36,900 Cum of waste material will be generated. This waste will be stacked in the dump yard located in the Northern side boundary of the lease area covering an area of 3,500.00 sqm to a height of 12 m with 450 slope angle.

Management of waste material shall include the following:

• Where the defectless and defective bands are distinct in the mine resorting to strip

mining may be helpful in reduction of waste. • Controlled and cushion blasting may be helpful in generation of less blasting waste. • Soil will be used for reclamation of degraded soil area.


13

• Weathered rock if it is sufficiently soft and devoid of rock fragments can be utilized for roads, filling of road side ditches, formation of approach roads to quarries, construction works etc.

• Large and medium sized waste rock can be used as revetment for deep cut stream sections from preventing from soil erosion. The waste generated during the mining will also be used for back filling of the mine pit after completion of mining.

6.6 Socio-economic Environment The occupation of the local inhabitants in surrounding villages of the mine area is

Agriculture and sheep rearing. The mining activity in this belt will benefit the locals both directly and indirectly. The directly beneficiaries will be those who get employed in the mines as skilled and unskilled workers. The indirect beneficiaries will be those who open small business to sell goods required by the residents whose “per capita” income will be enhanced by the mining activity, and thereby their purchasing power will be increased. In the long run a lot of social goods are expected in the comparatively backward area when the inhabitants will be able to send their children to school.

6.7 Occupational Safety & Health Management

• Periodical Medical Examination (PME) of all workers before recruitment and during mining operations.

• Total workers in the mine – 27 • Mine operators will be provided with personal protective equipments (PPEs)

include safety helmets and footwear, in addition to ear, eye, and hand protection devices.

• Dust masks will be provided for workers. • Potable drinking water & shelter for mine workers will be provided.

6.8 Monitoring during Project Phase (active mining) Pollution monitoring program includes periodic analysis of air, noise levels and

groundwater samples. Groundwater samples at representative locations within and nearby the lease area shall be periodically analyzed to detect contamination if any. In the event of any contamination, concerned authorities shall be notified immediately and appropriate corrective measures shall also be initiated. The monitoring shall also help in knowing the effectiveness of abatement measures and also be a guide for further steps to be taken, if required.


14

6.8.1 Monitoring Strategy

The monitoring of various environmental parameters is necessary and is a part of environmental protection measures. Monitoring is as important as that of control of pollution since the efficiency of control measures can only be determined by monitoring. A well-defined environmental monitoring program would be employed with trained and qualified staff to monitor the ambient air quality to check whether the quality of emissions/effluents is maintained within the permissible limits. Environmental attributes should be monitored as given below: • Ambient Air quality • Water quality • Noise levels • Soil characteristics Locations and frequency of monitoring should be as per the guidelines of APPCB.

6.8.2 Ambient Air Monitoring

As per MoEF there is a need to identify 3 ambient air stations at 120o angle keeping the main source in the center. The ground level concentrations of suspended particulate matter, sulphur dioxide and nitrogen oxides in the ambient air within the project boundaries will be monitored at regular intervals.

6.8.3 Noise Monitoring

Noise levels in the workspace environment will be monitored periodically. If any deviation is observed necessary corrective measures will be taken. Monitoring noise levels is essential to assess the efficacy of maintenance of schedules undertaken to reduce noise levels and noise protection measures. A good quality sound pressure level meter is essential for this purpose. This work can be handled by plant authorities themselves or by hiring services of an external agency. Noise surveillance is for the benefit of the workers wellbeing and to keep track of machinery wear and tear.

6.8.4 Water Quality Monitoring

Groundwater near the project site will be routinely tested for its quality. No contamination of groundwater is expected. Groundwater is recommended to be monitored in at least other wells/ bores in the area adjacent to the QL area in the direction of ground water flow to keep surveillance on the groundwater quality.


15

6.8.5 Use of Explosives

Blasting activities that may result in safety impacts are typically related to accidental explosion and poor coordination and communication of blasting activities. The proponent will be using low explosives and silent non explosive demolishing agents will be used to minimize the effects of vibration. Control measures to be taken during blasting are:

• Specific warning devices (e.g. horn signals, flashing lights) and procedures should be implemented before each blasting activity to alert all workers and third parties in the surrounding areas (e.g. the resident population). Warning procedures may be needed to include traffic limitation along local roadways.

• Actively managing blasting activities in terms of loading, priming, and firing explosives, drilling near explosives, misfired shots and disposal.

• Adoption of consistent blasting schedules, minimizing blast- time changes. • Rules and regulations laid down for safe storage and handling of the explosives as

per the explosives Act will be strictly maintained. • Specific personnel training on explosives handling and safety management should

be conducted. • Blasting sites should be checked post-blast by qualified personnel for malfunctions

and unexploded blasting agents, prior to resumption of work. 6.8.6 Machine and Equipment Safety

To prevent and control hazards related to machine and equipment use, measures for the enhancement of visibility should be applied throughout the mine. Specific visibility management practices may include the following:

• Use of reflective markings on structures, traffic junctions, and other areas with a

potential for accidents. • Use of contrast colouring on equipment/machinery, including the provision of

reflective markings to enhance visibility. • Use of moving equipment/machinery equipped with improved operator sight lines. • Installing safety barriers in high-risk locations of internal roads/transport corridors.

Barriers may be constructed with refuse or other materials capable to stopping vehicles

7 REHABILITATION AND RESETTLEMENT (R&R) PLAN

An extent of about 16,400 Sq. m area with 35 m depth will be sliced down during next Five years. The proposal for reclamation of land affected by mining activity will be done at the end of mining lease. No reclamation is proposed in this Five years period


16

because, the mining will be continued to further depths and reclamation will be possible only after completion of mining up to the proposed depths.

Reclamation and rehabilitation of the lands affected by mining will be done by back filling, soil amelioration and afforestation. This will be taken up on need basis before the conclusion of mining operations. The back filling of the mine starts from the Northern end proceeds towards Southern side. Drainage will be developed along the slopes of the hill. Reclamation of the affected land includes back filling, drainage development, spreading and fertilization of soil, leveling and re-vegetation etc. Care will be taken to implement the said factors.

8 PROJECT SCHEDULE & COST ESTIMATES

M/s. G.Mallikarjuna Reddy has allocated total budget for this project is 25 lakhs. Out of which 3.80 Lakhs (Capital Cost) and 2.31 Lakhs (Recurring Cost per annum) for the environmental protection measures.

9 ANALYSIS OF PROPOSAL (FINAL RECOMMENDATIONS)

9.1.1 Financial and Social Benefits with Special Emphasis on the Benefit to the

Local People Including Tribal Population, If Any, In the Area. The project involves extraction of Colour Granite. Although granite is a minor mineral, it is a major contributor in foreign exchange earnings. India is the second largest exporter of raw granite after China and ahead of Brazil and South Africa. This project will also provide employment to local people helping them earn livelihood.
