2. Quarrying
2.1 Proposed method of quarrying: The Ordinary sand is well exposed right on the surface, Quarrying will be continued from the downriver of the block to upriver of the Block 1 in the general direction of the lease. An open cast quarrying by semi mechanized method will be adopted to operate the quarry. Quarrying is planned by semi mechanized operation for extraction of Ordinary sand, screening, stacking etc. keeping the productivity and safety in mind. After screening, the rejection will be back filled in the excavated area. Only at the time of dispatches the JCB/ Loader will be used for loading the dumpers. No drilling is required as material is non compact in nature and easily dig gable.
6 2.2 Year wise production: For production, it is proposed to work from the North-West boundary of the Block and advance towards the South-East boundary.
Details are provided in Quarry plan
2.3 Drilling & Blasting: No Drilling and blasting is proposed in the quarrying process for ordinary sand as the Ordinary sand is course grained and not compacted. It is extracted mechanically by using excavator.
Blasting: A) As the Ordinary sand is course grained and not compacted, it is removed mechanically using excavator no blasting is required.
B) Whether secondary blasting is needed, if so, describe in brief:
Ordinary sand is removed mechanically by using excavator. No drilling and blasting is proposed.
C) Storage of Explosive:
No explosive is used for the purpose of blasting. Blasting is not required.
2.4 Loading: Loading will be done by the using Excavator/JCB/Wheel Loader to the trucks.
2.5 Hauling and Transport: The Ordinary sand extracted by using excavator & is screened by using gravity screens and the saleable product up to 8mm size sand is stacked separately for dispatches by dumpers to the consumer point.
7 2.6 Disposal of waste The nature and quality of top-soil, over burden waste and mineral rejects likely to be removed during the next five years:
There is a no top soil to be produced in the plan period. Only the rejection after screening in the form of oversize pebbles and clay shall be used for back filling in the excavated areas.
There is no such reduction of waste / mineral reject processing possibilities are proposed during plan period.
2.7 Employment potential
In all, there will be about 15 workers. Details are provided in Quarry plan.
3. Baseline Environment
3.1 Land environment In the proposed Mining activity there will not be much impact on the land environment due to the following reasons.
1. There is no removal of vegetation such as plants, bushes in the reach area
2. The proposed sand block area is situated on the surface of river bed. The land is not utilized for any other purposes, as there are no proposals for storage of the mined sand or is there any development involved for the proposed mining of sand.
3. No effluent generation as any further processing of mineral is proposed. Hence no ground water contamination due to the proposed mining activity.
8 4. The depth of mining shall be restricted to 2.66m/water level, whichever is less.
3.2 Water quality The quality of ground water is fairly good. There is no liquid waste discharge from mining activity, which is likely to pollute water.
3.3 Noise and vibrations Since it is small scale quarrying, where there is no drilling and blasting is proposed, there will be no back ground noise levels at the site. The area is away from roads where frequent traffic is encountered. General noise levels are expected to be less than 80 dBA. in the working of the mine.
Vibration levels: Blasting is not adopted in the quarry, Hence no vibration is apprehended in the mine.
3.4 Air Quality In general the SPM, SO2 and Nox concentration in the region may be within the permissible limits, as it is a small scale quarrying.
Control of air quality associated with operational dust:
• Water spraying will be conducted more frequently during hot
Weather and windy conditions.
• Enforcing speed limits on unpaved or untreated roads.
• Appropriate vegetation cover will be established as part of the
concurrent rehabilitation practices at the mine.
• The erection of shade cloth to act as windbreaks.
9 3.5 Climatic conditions The normal annual rainfall in the district based on 30years is 574mm. However, in the last decade (1996-2005) the district received an average annual rainfall of 631.7mm. Further analysis of rainfall data indicate that the there was deficient rainfall in the years 2003, whereas the year 2005 received excess rainfall. The taluks of Hiriyur & Chitradurga faced deficit rainfall in the years of 2002 & 2004 as well, most of the other taluks had deficit rainfall during two successive years 2002 and 2003. Post-monsoon rainfall had failed in the district during 2001 and 2004. During the year 2003 the pre- and post-monsoon season, rainfall had failed. Rainfall is lowest in Hiriyur taluk and highest in Chitradurga taluk Socio- Economic environment.
There are many villages within the buffer zone and they all depend on agriculture and related activities. Since the quarrying is on small scale, no health problems are anticipated as well as safety due to quarrying operations.
3.6 Socio-Economic environment There are many villages within the buffer zone and they all depend on agriculture and related activities. Since the quarrying is on small scale, no health problems are anticipated as well as safety due to quarrying operations.
10 4. Environmental Management Plan
4.1 Introduction The quarry operations in the study area, needs to be intertwined with judicious utilization natural resources within the limits of permissible assimilative capacity. The assimilative capacity of the study area is the maximum amount of pollution load that can be discharged in the environment without affecting the designated use and is governed by dilution, dispersion and removal due to natural physio-chemical and biological processes. The Environmental Management Plan (EMP) is required to ensure sustainable development in the study area.
This chapter covers the genesis of pollution, the principal sources of pollution, the nature of pollution, the proposed measures required for meeting the prevailing statutory requirements of gaseous emissions, wastewater discharge characteristics, noise levels etc. for environmental management purpose in connection with the quarrying and its related activities in the study area.
This section discusses the management plan for mitigation/abatement impacts and enhancement of beneficial impacts due to quarrying. The Environmental Management Plan (EMP) has been designed within the framework of various Indian legislative and regulatory requirements on environmental and socio- economic aspects.
Environmental Management Plan giving the environmental protection measures at quarry to meet the stipulated norms, are as detailed.
11 4.2 Environmental Impact Statement & Control measures
4.2.1 Climate The proposed quarry activities are not likely to contribute to any variation in the climate parameters of the region. The variations observed are on a regional scale and the control factors lie much beyond the small area considered for Quarrying. Hence no management measures are needed and proposed.
4.2.2 Air Environment No pollution is expected due to the quarry operation as the method adopted is Semi Mechanized in a small scale. Therefore, the SPM count in the air will not increase. Blasting is not adopted in the quarry, hence major air pollution is avoided to the maximum.
NOx, SO2 and CO values are expected to be within the permissible limits due to proposed, m quarrying. Effect of quarrying is minimal.
4.2.2.1 Dust Control The main source of dust is from transportation. The dust generated during the vehicular movement will be controlled by spraying water on village roads for which water tanker fitted with sprayer are proposed. Over loading of trucks and consequent spillage on the roads will be avoided. Measures such as covering tarpaulins over the loaded material will prevent spreading of sand from the trucks.
4.2.3 Noise Environment Noise will be produced at the quarry due to movement of tractors only. The noise generated by the quarrying activity is dissipated within a small zone around the quarry. The lease area is not inhabited by any wild life, as there is 12 no forest cover. Hence there will not be any effect on migration or extinction of wild life from the lease area as the noise created by the quarry operation is insignificant so as to cause any impacts. As the process involves only extraction of ordinary sand from the riverbed Semi Mechanized, there is no major noise generation; however the following mitigation measures will be followed to mitigate the noise generation 1. Speed of the vehicles in the village area will be restricted to 25 Km/hr 2. Vehicles with good maintenance will be utilized for sand transportation
4.2.4 Water Environment There will not be any wastewater discharges to water bodies from the mining operations. As proposed sand quarrying will be limited to 2.8m/water level, whichever is less, there will not be any intersection with ground water table. All the stipulations of MoEF for sand mining and guidelines as per the Karnataka Minor Mineral Concession (Amendment) Rules, 2013 will be followed. Hence there will be not be any impact due to the proposed quarrying on the water environment. WATER REQUIREMENT The proposed Mining activity requires 12.4 KLD of water. This includes water for domestic purpose. Water required will be sourced from bore borewells available in surrounding village The depth of mining shall be restricted to 2.8m/water level, whichever is less. Hence there will not be any significant impact on hydrology of the river.
4.2.5 Biological environment: As the area is devoid of any vegetation, surface sand mining is not going to cause any damage to any plant. There are no Turtle or Crocodile breeding grounds in the quarry lease area under consideration. Hence the anticipated negative impacts if
13 any are only minor, temporary and easily reversible. Natural restoration to original condition can occur within about one or five years. Hence it can be safely concluded that the proposed ordinary sand quarrying for five years as per rules is safe with very little negative impact.
4.2.6 Land Restoration/Reclamation The area granted for quarrying of Ordinary sand is purely in the river of Suvarnamukhi, a tributary to River Suvarnamukhi, water flows in this tributary river seasonally during monsoon and its spread over for a period of about 5 months and generally dry during rest of the period. In the buffer zone of 5 kms. major area is covered by Agriculture lands.
There is no such reduction of waste / mineral reject, these mineral rejects like shingle and pebbles at river bed will be dumped back in the worked out areas as a part of reclamation Topsoil Management
4.2.7 Occupational Safety and Health: The workers involved in quarrying and loading of sand will be provided with dust masks. Hence there will be no major occupational health hazards.
.
14 5. Conclusions
The depth of mining shall be restricted to 2.66m/water level, whichever is less. Hydrology of the river will not alter due to the proposed activity. The ground water table in the villages also will not be affected as the maximum proposed depth of quarrying will be limited to 2.66m/water level, whichever is less. All vehicles used for transport will comply with emission norms & noise level norms of the Ministry of Environment & Forests. Vehicles used for transportation of sand will be covered with tarpaulin. The quarrying operations will be in accordance with rules and regulations of Karnataka Minor Mineral Concession (Amendment) Rules, 2013 All environmental rules and regulations will be strictly followed and implemented.

INTRODUCTION Chitradurga District is located 200km NW from Bangalore, bounded by the geographical coordinates North Latitudes 13º 34' 20" to 15º 47' 10" to East Longitudes 76º 01' 30" 77º 01' 35". The District is having a geographic area of 8388.78 sq kms.
BRIEF HISTORY OF THE DISTRICT
Chitradurga district has a hoary past dating back to the pre-historic and legendary times. According to a tradition, it was near the Jatinga Rameshvar hill of this district that Jatayu challenged Ravana when, having abducted Sita, the latter was passing through this part of the country with her on his way to Lanka. According to another, during the period of their exile the Pandava brothers and their mother Kunti stayed for some time near Chitradurga hills. Some of the pot-shreds discovered in the pre-historic sites of the district are stated to be similar to those found in the Indus Valley, Sumer and Crete of the 3rd millennium B.C. Further, the ancient local culture which has been designated as "Roppa Culture" is said to be similar to the campiguin culture of France belonging to the period from 8000 B.C. to 6000 B.C.
Chitradurga features bold rock hills and picturesque valleys, huge towering boulders in unimaginable shapes. It is known as the "stone fortress" (Kallina Kote). The landscape looks much like a mischievous giant's playground, with boulders thrown around, forming silhouettes against the sky. According to a story in the Epic Mahabharatha, a man-eating gaint named Hidimbasura lived on the Chitradurga hill and was a source of terror to everyone around. When the Pandavas came with their mother Kunti in the course of their exile, Bhima had a duel with Hidimba. Hidimba was slain by Bhima and peace returned to the area. Legend has it the boulders were part of the arsenal used during that duel. In fact, the boulders on which major part of the city rests belong to the oldest rock formation in the country.
Y:\Chitradurga\sand\DISTRICT MINERAL SURVEY REPORT.doc 4
Timmana Nayaka a chieften under the Vijayanagar empire rose to the rank of governor of Chitradurga as a reward for his excellence in military achievements, from the Vijayanagara ruler. This was the beginning of the rule of the Nayakas of Chitradurga. His son Obana Nayaka is known by the name Madakari Nayaka 1588 CE. Madakari Nayaka's son Kasturi Rangappa 1602 succeeded him and consolidated the kingdom to rule peacefully. As he had no heirs to succeed him, his adopted son, the apparent heir was enthroned but was killed in few months by the Dalavayis.
Chikkanna Nayaka1676 the brother of Madakari Nayaka II sat on the throne, and his brother succeeded him with the title Madakari Nayaka III in 1686. The unwillingness of Dalawayis to accept Madakari Nayaka III's rule gave an opportunity to one of their distant relatives, Bharamappa Nayaka to ascend the throne in 1689. He is known as dthe greatest of the Nayaka rulers. Somehow, the subjects of Chitradurga did not experience a good reign of the successive rulers as they ruled on the throne for very brief periods. The Hiri Madakari Nayaka IV 1721, Kasturi Rangappa Nayaka II 1748, Madakari Nayaka V 1758 ruled this area but there is not much to mention of their rule.
Chitradurga Fort:-
The old walled Town houses the impressive fort, built on the north eastern base of a cluster of rocky hills, qualifying it to be a Giridurga, or hill fortress. Known as Yelu Suthina Kote, the fort is fortified by seven circular walls, three of which are on the ground and four on the hill. Chitradurga fort is said to have had 19 majestic doors, 38 smaller doors, 35 special entry points and four secret entrances. The fort is entered through four gateways of the outermost wall. The foothills of the fort constitute the main residential area of the town. The Mel Durgas, forts on the hill are embellished with extensive fortifications, ramparts, bastions, batteries, watchtowers and entrances located at strategic points and
Y:\Chitradurga\sand\DISTRICT MINERAL SURVEY REPORT.doc 5 house fourteen temples. Some of the fort’s important landmarks are Thuppada Kola Betta, Hidimbagiri, Zadaa Battery (Flag battery), Kahale Battery (Trumpet battery), Lal Battery (Red battery) and Nellikai Battery (Gooseberry battery). The main entrance to the fort, Kamanbhavi, has carvings of the seven – hooded cobra the legendary twin headed bird, Gandaberunda, the royal swan,Rajhamsa and lotus flowers.

GEOHYDROLOGY AND OCCURANCE OF GROUND WATER.
The above major rock units are Hard, crystalline Rocks, which have been subjected to Tectonic Movements. The process of weathering produces joints primarily by means of Temperature effect on Rock, as well as by Chemical and physical action of Flowing Water. So produced joints by weathering rapidly lies down within the upper 30 to 50mts in most Cases.
The most dense joint sets of the above origin can be observed in the upper portion of the hard rock massifs. These joints may either open filled (mineralized) fill being represented by sandy, clayey material or veins of Quartz.
The character and extent of joint depends upon the composition and hardness of the rocks. Harder rocks are less rapidly disintegrated, hence joint penetrate them down to smaller depths.
In hard rock formation cut by differently oriented and mutually intersecting joints can also be seen. Granites and other crystalline rocks often contain little water. Which extend down to the depths of 30 to 50 meters and very rarely 100mts.
The distribution and migration of ground water in jointed rocks are variable, being dependent upon the Character, origin, and size of the cracks. Joints in hard rock contain both Semi confined and unconfined ground water. Ground water head is commonly produced by the Hydrostatic pressure in intersecting joints, some of which occur in a recharge area at higher altitudes, where the rain water and surface water infiltrate into the ground, in other places, the water pressure in cracks in cracks is related to the pressure of gases ascending from lower zones of the lithosphere. Major fracture zones also
Y:\Chitradurga\sand\DISTRICT MINERAL SURVEY REPORT.doc 10 contain ground water and these acts as good aquifer. Metamorphic rocks are mainly Hornblende Schist and Chlorite Schist and Granite Gneiss.
The prominent water bearing zones are Secondary structures such as pore space, joints and fractures in the different rock types that act as good Aquifers. The depth of weathering zone varies from 10 to 20m. The depth of joint/ fracture zone varies from 20 to 90 m and the isolated fracture and joints may extend down to a depth greater than 90m but less than 120m. Major structural features, are fractures and fissures that occur in the rocks, than these features acts as sub surface reservoir to hold and discharge ample quantity of ground water.
GEOLOGY AND AQUIFER SYSTEM.
The rainfall precipitation is the only source for ground water recharge. The total recharged water will be stored approximately at the following depth in all geological setup. The thickness of the water bearing formation i..e, aquifer as follows.
Maximum water will be stored in weathered / jointed / fractured rock formations, up to a depth of 30m below ground level(bgl) and it accounts approximately to tune of 65%to 75% of the total estimated ground water recharge and 10% to 15% of the ground water will be stored at a depths ranges from the 30 to 60m (bgl) in semi weathered rock formations (Granite, Granite Gneiss, Schist) with joint / fractures, and 5%-10% of the ground water will be stored at a depths ranges from the 60 to 90m (bgl) in hard rocks with fractures and less than 5% of ground water will be stored at a depths ranges 90- 130m(bgl) in hard rock, with isolated fractures.
Review of ground water quality changes.
The objectives of the water quality monitoring net work is to: Establish the Bench mark for different water quality parameters
Y:\Chitradurga\sand\DISTRICT MINERAL SURVEY REPORT.doc 11
Compare the different parameters against the national standards. Detect water quality changes with time Identify potential areas that show rising trend
Detect potential pollution sources
Study the impact of land use and industrialization on ground water quality.
To study the ground water chemistry, ground water quality-monitoring network, has been established at 47 villages. From all the stations Base and Trend water samples are collected and analyzed since many years. It is observed from the analyzed report that Base samples shows higher concentration of the substances or Characteristics like PH, CaCo3, Cl, Fe, TDS, SO4,F and NO3 when compared with Trend samples Characteristic Values. Ti is also noticed that concentration of the substances became low and dispersion will be more in large area in Trend samples. The frequency of monitoring for ground water quality is changed as base line monitoring where as samples are collecting once in a year (one time a year) wells showing abnormal parameters for trend monitoring (2 times a year) where as wells for surveillance monitoring nil.

Mineral Resources of Chitradurga District Chitradurga district is one of the mineral rich district in the state, where many types of minerals. Thin bands and lenses of barytes upto 1 m wide and 200 m long occur in association with the fuchsite quartzite bands of Sargur Group in the Ghattihosahalli and adjacent areas.
Copper, Gold, Silver: A belt of polymetallic sulphide mineralisation with a copper, lead, zinc, antimony, arsenic, gold and silver, has been traced over a strike length of about 40 km, along the eastern part of the schist belt. This mineralised belt designated as the Chitradurga sulphide belt, extends from Chikkahonnanahalli in the north to Yarahalli in the south. Copper mineralisation is prominent in the Belligudda-Ingaldhalu- Kunchiganahalu sector over a strike length of about 5 km. The Ingaldhalu mines is located in this sector. At Ingaldhalu, chalcopyrite with minor pyrite, pyrrhotite, galena and sphalerite occur as disseminations, stringers and fracture fillings in quartz veins occupying narrow shear zones in the meta-basalts. The Belligudda-Ingaldhalu-Kunchiganahallu section has been explored by drilling, jointly by GSI and the Dept. of Mines and Geology, Govt. of Karnataka. On the basis of drilling data and the mine development data, reserves of 2.14 million tonnes with an average copper content of 1.22% are estimated in the mine blocks, northwest and northeast block. The copper ores also carry considerable silver and gold content. INGALDHAL COPPER MINE (CENTRAL BLOCK) : This mine is situated south of Chitradurga. HGML has got Mining Lease (ML No: 2490, Period: 06.03.1993 to 05.03.2013). Mining activities at Ingaldhal Copper Mine were carried out from 1965 to 1994.
Y:\Chitradurga\sand\DISTRICT MINERAL SURVEY REPORT.doc 18
So, Mining work was suspended in 1994. due to world globalization and cause decline in Cu price as well M/s. Hindustan Copper Limited had stopped buying of copper concentrate. It is planned to carry out further detailed exploration by exploratory mining, reclamation. For this statutory works are in progress. GUDDADA RANGAVANA HALLI (G.R.HALLI): Guddadarangavanahalli Gold Deposit is situated 7km North East of Chitradurga and is 15km North West of Chitradurga Gold Unit and is situated on Bangalore-Sholapur National Highway No.13 with a 1.5km mud road takes to the deposit. This is a polymetallic deposit, reopening of the mine is under consideration. It is planned to carry out further detailed exploration by exploratory diamond drilling followed by reclamation and mining. For this statutory works are in progress.
