0.0 INTRODUCTION
1. Samim Khan has been granted mining lease for three (3) years to mine sand from the River Koel, covering an area of 15.00 Ac. i.e. 6.075 Ha.
The right to extract sand from the above mentioned river bed for the specified period has been obtained by the lessee after his successful participation in the bidding process conducted by the State Govt. (Jharkhand) through authorized officials.
The leasehold area comes under Olmunda Mouza (Pat Sarna Ghat) in Gumla District of Jharkhand. As already mentioned the total area for which lease for sand mining has been granted is 15.00 Ac. i.e. 6.075 Ha.
2. Originating from high lands of Palamu district the River Koel enters Gumla district after cris- crossing undulating plateau region of the area. In Olmunda mouza under Sisai police station, the River Koel flows lazily as the terrain over which it passes is almost flat. After crossing the Jharkhand territory the River Koel meets the Vedvyas River in Odessa State.
3. As per the directives of the State Govt. lessee can initiate the process of sand mining after getting approval of the „Mining plan‟ pertaining to the leasehold area and environmental clearance (EC) from the competent and authorized State Govt. Department (S)/ Agencies.
4. „Sand‟ meant for various construction purposes like building construction, roads and bridge etc. has been categorized as „minor‟ mineral and therefore relevant rules, regulations etc. are applicable for mining of river bed sand.
5. Sand is one of the important raw materials required for all types of construction activities. The real estate sector in the region is witnessing impressive growth particularly during last decades. It is expected that not only the real estate sector but the future industrial growth scenario in the state/region are bound to increase the demand for sand. It is impedient therefore that sand as one of the essential raw materials for construction purpose should be available on sustained basis and at affordable cost. At the same time, the local people living near the river should derive economic and social benefits as they also are important stake holders of the entire exercise.
1 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
6. The „Mining Plan‟ for sand mining has to conform to the relevant mining and environmental acts, rules and regulations. These aspects have been given due cognizance while drawing up concept of sand mining in the report including guidelines/ directives issued by the Govt. of Jharkhand.
7. The „Mining Plan‟ preparation is broadly based on;
Maps and data provided by the applicant/ lessee. Site visit, survey by GPS and collection of available data/ information. Prevailing technical norms. Help of standard publication, books, maps etc. along with appropriate assumption wherever thought necessary.
8. Required number of manpower including supervisory have been recommended in the „Mining Plan‟ for properly carrying out safe and techno- economically competent sand mining.

03. GEOLOGY AND RESERVES
03.01 Mechanism of Sand Formation
The River Koel courses through both mild undulations and plain basin. Gumla district is located in the south- western part of the state and display most of the characteristics of Ranchi plateau. Geologically the area comprises of Archean Granite and Gneisses. Dolerite rock in the area can be seen exposed both in the form of sheet rock and batholitic. In general, the mass crust and a little deep of the area consist of alluvial soil.
Deposition of sand on river beds is a continuous process which gets vastly accelerated during monsoon period. Basically, sand particles in different assorted sizes are formed due to various natural processes. The agents responsible for sand formation are:
Breaking down of boulders of various sizes coming in the path of running current of river Collision among rolling stones/ pieces Weathering action of high wind Thermal and frost action Configuration of the river i.e. whether prominently meandering or has comparatively less curvature
Depending on the water current/ velocity, river slope/ hydraulic gradient, traveling distance etc. sand particles get deposited on river beds. Again depending on the intensity of erosional agents, the sizes of sand particles formed will vary from coarse to fine.
In general, the sand deposits are classified in order of sizes as:
Grit Coarse and Fine
The most important factor which contributes to the size of sand particles is the velocity of river water. Lower the velocity, finer is the sand size.

03.02 Geological Features Gumla district is located in the south-western part of the state. The geological set up of the district is part of Ranchi plateau. The northern part of the district has a higher elevation plateau area having an average elevation of around 700m.
The general slope of the district is from north to south. Geologically the area comprises of Archean granite and geneisses. In the uplands considerable thickness of laterite of Pleistone age is found in the granite and gneisses tracts. Alluvium of recent to sub-recent age is found in the river valley.
The part of the river within Olmunda mouza flows through almost flat terrain. The bank formation is of alluvial soil.
The sand formation is comparatively more in thickness in the Koel river particularly in the study area.
03.03 The River Koel originates from Palamu district and the flows through Gumla district (Sisai block) after cris- crossing undulating Plateau region of the area. Its travel through the leasehold and contiguous stretch is almost over flat topography. The river completes its journey by merging with the River Vedavyas in the state of Odisha.
The general features of the river are; The river passes through alluvial soil and weathered sand stone formation. The leasehold part is almost straight except some curved part along southern bank. The depth of river bed varies from 3.4 to 4.0 m.
The sand sizes are predominately of fine textured with occasional coarse particles. Small pebbles occur in scattered manner but mostly seen near the river banks.
Pebbles are both rounded and slightly elongated in shape. The geological plan of the river bed has been shown in plate no. 05

03.04 Exploration
The standard practice of exploring mineral deposits are by driving boreholes after deciding on an exploration plan on drawing board. However in the sand formation/ deposit, the simple method of making hole up to sand bed bottom with the help of either mechanically or manually operated augers will meet the purpose of assessing the deposit potentiality and other characteristics with reasonable confidence level.
Few points from upstream side at random intervals can be chosen as exploration sites. The results available from driving up to sand bed bottom from these sites can be projected to draw section lines at intervals depending upon the spread and shape of the river bed.
In the absence of exploration data available through boring etc, the observation made during site visit and information collected have been taken as exploration details. As per field evidences and details provided by both the lessee and local people, the depth of the sand bed is reported to vary from 3.4 m to 4.0 m. These are more or less in conformity with the projected depth obtained while estimating the sectional areas at selected points.
03.05 Reserve
Estimation of reserves has been done through cross- sectional method of computation.
Based on site visit, physical dimension of the lease area and sand bed characteristics like thickness, granular size etc. section lines have been drawn on the geological plan after deciding on adequacy of number of sectional area. The river bed area coming within the granted leasehold boundary is almost straight barring at some part along south bank. The width of the river bed vary between 149m to 238m within the allotted length of the river bed.
For reserve area estimation few sections have been taken. Sectional areas at each section have been computed. The sections have been nomenclatured as A-A‟, B-B‟, C-C‟, D-D‟, E-E‟, F-F‟ and G-G‟.
9 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
The sectional areas have been placed in two parts. One is the total area and the other is the „Mineable‟ area. The mineable area has been fixed up after leaving one fifth (1/5th) of the river width or 15m width whichever is more and restricting the sand extraction up to 3m of depth from river bed top level.
Both the barrier lines i.e. 1/5th of the width as well as the line indicating the 15m wide barrier have been shown on each plate representing leasehold part on the river bed.
The leaving of safety barrier and restrict the sand mining up to 3m of river bed are statutory requirements.
The section lines taken for area and reserves calculation are A-A‟, B-B‟, C-C‟, D-D‟, E-E‟, F-F‟ and G-G‟. The sectional details have been shown in plate no. 5A.
The total (Geological) reserves (volume) and mineable volume have been estimated by multiplying sectional areas with the length of influence.
The length of influence is the half distance between two consecutive sections.
The estimated volume both total (Geological) and mineable have been indicated in table nos.03.01 and 03.02 respectively.

In both the table nos. 03.01 & 03.02, „A‟ represents sectional area in sq. m whereas „L‟ denoted length of influence in meter.
It can be seen from the table no.03.02 that the total mineable sand volume is in the region of 110403 m3. This can be taken as 108000m3 after allowing for losses etc. If compared with total volume of sand reserves estimated within the allotted part of the river bed i.e. against 222371m3, the mineable reserves works out to around 49.64 percent.
03.06 Anticipated Life of the Mine
Due to steady flow of the river during rainy season sand reserves in river bed almost gets replenished every year. Therefore in the case of sand mining, the life cannot be determined as opposed to mining of other minerals both major and minor mining of which is regarded as a wasting asset.
In the process of sand extraction, some percentage of the mineable sand remains in the river bed which can be termed as mining loss. Spillage of sand during transport within the river bed also contributes to some extent in replacing the mined out sand.
On the basis of the reasons described in the above paragraphs and mainly due to natural sand replacement phenomenon it can be said that near normal replacement is possible if the sand extraction rate is maintained within mineable quantity of sand reserves.

04 MINING
04.01 General
The entire river bed within the leasehold area is available for sand extraction. The first requirement is to locate one or more existing approach road or improve/ develop approach road to have access to the sand mining area. This approach road will be connected by temporary/improvised roads to the sand mining site. The temporary roads are generally constructed by pebbles and boulders available near the site.
Extraction of sand from river bed will be through the manual means.
04.02 Envisaged Production Capacity
The mineable reserve from the river bed has been estimated as 108000 m3. Which means that 480m3/day, the daily extraction rate of sand will be around 480m3/day.
The sand extraction rate has been decided taking in to account the
following features. Estimated mineable reserves. Carrying capacity of the existing roads i.e. infrastructure facilities. Managing various aspects of sand mining operations. Sensitivity towards environment and ecology which is of prime importance.
On the basis of these considerations, the production target has been planned to be 108000m3/year against available mineable reserves of 110403m3. This will allow for adjustment towards mining and handling loss. .
Therefore the production schedule will be as under;
i) Annual production : 108000 m3 ii) Monthly production : 12000 m3 iii) Daily production : 480 m3
12 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
04.03 Sand Mining Methods
The mining methods applicable for river sand is decided taking into considerations certain constrains such as flow of river and disposition of exposed sand bars.
There are various mining methods for mining of sand from river bed. The following two methods of sand gathering are more prevalent in our river sites; i) Manual winning and loading of sand on tipper trucks / trucks/ tractors. ii) Mechanized winning and loading of sand by excavators (shovels/backhoe/pay loaders) on to dumpers/ tipping trucks.
Taking in to consideration the production schedule and disposition of sand mining area it has been decided to adopt manual method of sand extraction and loading for this sand mining project.
Adoption of manual mining method will help the local people to get employment particularly during the non- monsoon period, when there will be not much work related to agricultural activity like field preparation, seeding and sowing.
04.04 Mine Development Strategy
Considering the general characteristics of the river bed like nature of deposit (loose or compact), gradient (Flat, slightly dipping) etc, it will be suitable to mine the sand directly from river bed by manual means.
The excavated sand will be loaded in to trucks and tractors by the miners manually. For the transport vehicles to make access up to sand mining site one or more make shift approaches at suitable location and intervals will be made.
A stretch of river bed from one sides of the river bank boundary will be left intact. It will be one fifth of the width of the river or 15m whichever is more. At each section this distance will be plotted and then all the points will be joined by a line. This has been drawn in the geological plan.
Generally it has been observed that on an average, bulk of water flows over the sand layers in the river during the three months in a year i.e. the
13 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
peak monsoon period. No sand mining operation is possible during those months. Therefore sand gathering process will be the nine (9) months of a year when river bed remains almost dry or with very less flow.
04.05 Mine Operational Regime Working months in a year : Nine (9) Working days in a month : 25 days No. of working shifts per day : One No. of hours per shift per day : 8 hours Available working hour per shift : 6 hours Effective working hour per shift : 5 hours
04.06 Layout of Mine Workings
At first depending upon the length and width of the river bed, the entire leasehold area will be divided into few patches. The patches will be sub- divided in small strips for sand extraction depending on distance between two patches. The area between two sections will serve as one patch.
In the present case because of variation in width and more or less straight shape, the whole of the leasehold has been divided in to seven (7) main parches. The area between two section lines is taken as one patch. The sand volume occurring within these patches will be extracted after dividing it in to 2 to 3 strips as per mining convenience.
Plate no. 6 shows a schematic layout of the proposed sand mine indicating sequence of strip mining operation. Sand will be won along the deposit of exposed sand bars in a strip fashion. Strips will be marked up to the boundary of proposed sand lease area. As mentioned, the sand mining process will be initiated from downstream side of the lease limit and progressively advance towards upstream side lease limit. However, it will not be out of place to mention that sand mining layout can be flexible depending upon site condition, availability of man power and transport facilities. Also, market demand on a particular period may dictate the planning schedule of sand extraction.
14 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
Overall advancement of all the mining activities will be towards upstream side. Simultaneous extraction and loading of sand will take place from
more than one site at a time.
In the course of manual mining, miners will place themselves in midway of the selected strip and sand will be mined from both toe and crest of same bench. The sand bed of 3m can be mined in three stages of 1m high each. After taking one initial mining cut from the boundary of the mining lease area, the sand mining will be carried out in retreating order from the boundary in regular strips towards the upstream side. The process has to be carried out in such a manner that the flow of river channel is not obstructed. Sand mining will be restricted up to the permissible limit from the river bank. The proposed working parameters will be as mentioned below:
Sl. No. Parameters Unit Value 1. Bench Height M 1 2. Working Bench Width M 8 to 10 3. Bench Slope Degree 300- 350
04.07 Method of Working
As already discussed, the process of sand mining will be manual. Both the operations of sand gathering and loading in to transport vehicles will be carried out manually.
After marking the working area in a number of patches and strips which has been spelt out in the previous paragraph, depending upon the production target simultaneous sand extraction and loading from a number of points will be planned. The transport trucks/ tractors will be brought up to the sand strip to be mined. The miners will form a group of 5 to 6 persons at one mining cum loading points. While two persons will excavate sand from sand bed another two will fill the materials in to baskets. Rest one or two of the workers will load the waiting vehicle meant to carry sand from river bed to destination areas.
The implements and facilities to be required for mining and loading will be mainly hand operated shovel (Belcha) and baskets made of iron, apart 15 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
from transport vehicle like trucks/ tractors etc. Some auxiliary facilities like provision of a water sprinkler for dust suppression on the access road will also be needed.
The schematic layout of the mine working has been already discussed in para 04.06 and shown in plate no 6
Cycle of sand mining operation will be: Digging and sand gathering Placing the excavated sand in to basket/ trucks Loading of sand in to transport vehicle from the basket 04.08 Notes on Conceptual Plan for Lease Period
The concept of mining sand from the river bed has been already discussed in preceding paragraphs.
Geologically, the sand formation process is triggered by a number of natural and mechanical agents like disintegration of rocks due to mutual collision, wind velocity, water current, thermal spalling etc and the repetition of these forces on a continuous way, replenishes the sand mined out from the river beds. Therefore the resource from river bed is more or less assured in every year after monsoon.
The same method of mining is followed in each year of the lease period as soon as work re- starts after monsoon break.
It is imperative however to take due consideration after diligent survey/ study the likely impact on environment and ecology of the area due to the process of sand mining activity in the river bed. The activities may have some impact both on terrestrial and aquatic environment.
In the „Mining Plan‟ report based on base line data and mining operations suggested, all possible environmental related factors have been analyzed and wherever required feasible mitigation measures have been suggested.
These have been embodied in the relevant chapter i.e. chapter „Environmental Management Plan‟.
16 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
The total lease area is 15.00 Ac. i.e. 6.075 Ha which will be put in to sand mining purpose every year and at the end of three years‟ lease period, the status of the lease area as regards to total land as well as surface topography, bank level etc. will remain/ be restored as it was before the start of mining of sand.
04.09 Drilling and Blasting
Sand mining operation due to very nature of its physical properties like hardness, size and depositional features preclude the necessity of resorting to drilling and blasting to win sand mass.
04.10 Loading and Transport
As explained in earlier chapter/ paras, the loading of excavated sand will be in to trucks or tractor manually.
A group of five (5) to six (6) persons generally form one unit both for extracting and loading of sand as mentioned earlier.
Depending upon the production target, the numbers of units inter- alia loading points are fixed. Loading and excavation will take place simultaneously from all the selected points or sections. The production target has been pegged at the rate of 480m3 for which the number of units (groups) required will vary from 5 to 6. Considering six (6) persons forming one group, the total manpower required to be deployed for sand extraction, gathering and loading will be around 36. Keeping a provision of 20% as absentees, the total requirement of miners will be in the region of 43 or say 45.
Requirement of transport trucks will be depending on whether the consumers/ consuming units will provide their own transport facilities or not. Usually, it is the consumers who carry the loaded sand by providing their own transport trucks. Alternatively it can be a mixed bag type system in which the lessee will maintain some of transport vehicle and rest will be arranged by the consumers.
Considering all these factors, it is recommended to maintain combination of a numbers of trucks and tractors by the lessee so that supply of sand is
17 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
maintained uninterruptedly and the work force do not idle in the event of non- availability of trucks etc.
As regards to the total requirement of transport facilities it is not possible to estimate very precisely in this case as the hauling distance is not fixed or known. The arrangement should ensure that there is not much break in the sand gathering and loading operation due to non- availability of trucks/ tractors etc.
While one fleet of vehicles will be under loading, another fleet will be moving with loaded sand. At the same time empties will wait on the river bank or near the causeways.
04.11 Drainage
Since the sand mining operations are not under taken during rainy season arrangement for de- working is not warranted. The existing flow path of the river water will not be disturbed during sand extraction process.
04.12 Implements and Transport Facilities
For carrying out sand mining manually the facilities in the form of implements like hand shovels (Belcha) and iron baskets will be required. For transport of sand from river bed both tractor trailer combination and trucks will be deployed.
To aid in sand gathering as a heap, small sized iron plates or pans will be helpful. These will perform the duty of a minor dozer to some extent.
As already mentioned, the transport of sand from river bed will be both through the transport facilities arranged by the end users as well the facilities available with the lessee.
As the distance of transport is not known or fixed and exact division between captive vehicles and transport facilities likely to be arranged by consumers is also will vary therefore the numbers of trucks and tractors to be deployed have been decided on ad hock basis leaving the provision of additional requirement with the consumers.

08. ENVIRONMENT MANAGEMENT PLAN
Environment Management Plan comprise of three aspects:
i) Collection of base line data ii) Environment Impact Assessment Study (EIA) iii) Environmental Management Strategies to ameliorate impact on environment and ecology.
08.01 Base Line Data
08.01.01 Existing Land Use Pattern
The leasehold is river bed from which sand will be extracted for construction purposes.
The whole of 15.00 Ac. (6.075 Ha.) of the leasehold area is thus unutilized terrain. The existing land use can be represented like; Forest land : Nil Govt. vested land (River) : 15.00 Ac i.e. 6.075 ha Private land : Nil
08.01.02 Water Quality
Proposed sand mine is situated in the Koel River. The present use of river water is by local villagers and is in undisturbed condition i.e. in ambient status in and around the proposed leasehold area.
08.01.03 Flora and Fauna
Flora
The area falling around the deposit does not have vegetative cover of worth mentioning. Few trees of different height can be seen at distant locations in adjoining fields.
The area is non- forest land and there is no evidence of rare herbs or medicinal plants and endangered species in the sand mining site. The core zone is devoid of any flora what so ever.
The area within buffer zone is
Agricultural fields Barren land 24 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
Patches with medium height trees Fauna
The River Koel is not of perennial type. The fishes and snakes are usual seasonal aquatic fauna.
08.01.04 Ambient Air Quality
Since, there is no industrial activity in or around the sand mining site, the air quality of the area is expected to be within desirable norms.
08.01.05 Climatic Conditions
The general climatic nature of the Gumla district prevails in the proposed area of mining.
In winter temperature varies from 30 C to 120 C whereas during summer temperature ranges from 300 to 420 C. Month of May is the hottest whereas in the month of December, winter attains its lowest temperatures.
The district receives an annual rainfall of around 1100- 1200mm.
08.01.06 Human Settlements
There is no human settlement within 500m of the core zone area.
08.01.07 Public buildings, places of worship and monuments
There is no public building historical monuments etc. within 500m zone of mine site. The following villages are located within 5 km from the mine lease area: Name of Village Towards Distance Population Olmunda East 1.5km 5000 Sikaria Toli West 2km 700
The river within the leasehold part north- west to south east direction.
08.01.08 Does area (Partly or fully) fall under notified area under water prevention and control of pollution Act 1974
The area does not fall under the Act.
25 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
08.01.09 Socio- Economic Status
The local people mostly depend on agricultural activities which provide engagement for part of the year. Some work as daily wage worker in construction and similar sector.
08.02 Environment Impact Assessment
08.02.01 Relief and Landscape Alteration
The relief of the sand bed to be put under sand mining will loose its natural relief during the period of mining which cover about nine (9) months i.e. the mostly dry period of the year. The river bed will regain its original configuration almost is its natural status during 3-4 months of rainy season when water current from upper reaches of the river will carry sand particles and deposit in on the river bed in the course of its journey downstream.
This particular river bed leasehold is almost flat in topography. Therefore the rate of deposition of sand is very impressive. Even after the extraction of the 3m top layer of the sand, the river bed will be left with 0.4 to 1m of thick sand layers.
The mining activities will not have any impact on landscape as there is no cutting or felling of trees is involved. Also no structure will be dismantled.
08.02.02 Water Regime and Quality
Mining activities will not disturb the existing drainage pattern of the river, Mining activities will be carried out in dry seasons and bed topography will get restored during monsoon days.
Though no water quality analysis report on samples collected from the river is available, the future mining will not interfere with water regime or effect the quality as the process is gradual and limited in nature.
There will be no pumping of water from mine site. No effluent will be generated by sand mining process. Hence, no impact on water quality is envisaged due to mining of sand.
The mining will be restricted maximum up to 3m of sand bed depth and thereby no interference with water level below is visualized. 26 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
08.02.03 Air Pollution
Sand will be mined from river bed. The sand will be in wet condition as the excavation involves up to 3m of depth. Therefore partly wet sand will not generate fugitive dust. During transport through trucks also, the sand will remain moist. Traffic volume being intermittent the emission from vehicular movement will get diluted due to normal air velocity of the
surroundings.
08.02.04 Noise
There will no major mining machineries involved in sand mining and therefore except plying of transport vehicles there will be no source for generating slightly high decibel level.
08.02.05 Socio-Economic
Mining operation will provide direct and indirect employment for local people. Infrastructure like road condition may improve. The local villagers will be helped by arranging periodic health care camps and distributing study materials for their children.
The suggestion of manual sand mining has some socio- economic angle. The sand is being mined from the area where the local people also form important stake holders. Therefore, at least a section of the population will get some alternative means of employment particularly during the period when there will be less agricultural activities.
08.03 ENVIRONMENT MANAGEMENT PLAN
08.03.01 Relief and Landscape Alteration
The original configuration of the area from where sand mining will be carried out will undergo changes gradually and temporarily as the material will be extracted from top to bottom horizons. Moreover, a certain percentage of mineable reserve will remain on the river bed as residual volume of sand.
The original configuration will get almost restored during rainy season. Therefore, the impact on land use is reversible. The area is devoid of vegetation. 27 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
08.03.02 Impact on Water Table and Water Contamination
As already stated, the working of the mine will not disturb water table level till the plan period. Periodic sampling of water will be carried out for analysis.
08.03.03 Dust Suppression To deal with possible fugitive dust particles due to trucks plying over the access road, periodic water spraying will be done. Development of green belt will help in dust suppression also.
08.03.04 Noise Pollution
Mining of sand being manual operation will not be source of noise pollution. It will be seen that transport vehicles are maintained properly so that both noise level and emission of noxious gases remain under control.
Regular sampling for dust generation at selected places as well as survey for noise level will be carried out as per approved sampling plan of Jharkhand State Pollution Control Board (JSPCB). This will apply for water sampling also.
08.03.05 Sampling Plan For regular monitoring of water and air quality as well as noise level survey, monitoring stations within core and buffer zone will be selected as per site condition and work schedule. Two to three stations will be selected on random basis beyond core zone to monitor dust particle concentration and noise level status.
08.03.06 Afforestation
To maintain and improve the ecological status as well as create aesthetically beautiful surrounding, some of the identified areas will be taken up for gradual plantation purpose. The main area available for plantation will be the stretch of river bank.
The length of the plantation stretch cover the leasehold side bank if, the peripheral area of the bank is available for taking up afforestation scheme. This will be firmed up according to site condition. Access roads to the sand mining site can be taken up under road side plantation scheme
28 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
provided required permission is obtained from local bodies i.e. village panchayat and land owners.
A tentative year – wise afforestation programmme will be developed in consultation with local panchayat and district forest officials
The total length of the river bank within the leased out part is varies between 631m and 632m. Two rows of tree saplings will be planted along the stretch. In addition to this, the approach road to the sand mining site will be taken up in the line of avenue plantation. The exact number of saplings to be planted will decided as per site condition and guidance from the forest officials.
The first row of sapling to be planted will be kept at least 5m away from bank boundary. For selecting type of plant species, advice from district forest office can be sought.
To improve soil condition, initial as well as periodic dosing of proper type of fertilizer will be done.
After plantation, proper after care schedule will be followed and withered sapling will be replaced by fresh one which will depend on survival rate of saplings planted. For green belt development, expert advice can be sought from forest department.
08.03.07 Budgetary Provision for Environmental Management
Environmental Management Activities will comprise of green belt development, bank stability management, sampling, analysis of samples and monitoring of environmental parameters status, dust suppression as well as health and safety.
The scope for land reclamation does not exist but bank failure and erosion activities will have to be prevented.
A provision of rupees five lacs will be kept to initiate and maintain the environmental and ecological balance.
The measures to be incorporated for environmental management has been shown in plate no. -7 titled as “Environmental Management Plan”.

The applicant will make available the status of implementation including deviation, if any from mining plan with reasons for such deviation.
09.04 Closure Plan Describe the proposals to be implemented for reclamation and rehabilitation of mined – out land including the manner in which the actual site of the pit will be restored for future use.
As the final closure period approaches, the main areas to be concentrated are:
a). Technical Aspects b). Environmental Aspects and c). Socio- Economic Aspects
a). Technical aspects encompasses:
i) Safety and Security- In the mine closure plan action will be taken to cover all the safety aspects including management of mine inundation/ flooding.
ii) Management of Hydrology and Hydro- geology- The river bed will be left as it was in its original land form so that it continues to remain source of water supply to the neighboring areas.
iii) Closure of Mine Entries- After closure of mining activities, all the approach roads/ temporary improvised approaches to the river bed site will be effectively closed/ the material used for laying temporary cause ways will be removed.
iv) Disposal of Mining Machineries- In this case of manual operation no heavy earth moving machineries (HEMM) is involved.
v) Dismantling of Surface Structures etc.- There will be no surface structure requiring dismantling.
37 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
vi) Service Buildings- This is being mostly a semi- permanent type of set- up, the structures will be dismantled.
vii) Disaster Management and Risk Assessment- This should deal with action plan for high risk accidents like landslides, subsidence, flood, fires, seismic activities, tailing dam failure etc. The capability of lessee to meet such eventualities and the assistance to be required from the local authority should also be described.
Risk factors such as seismic activity, subsidence, flood, fire, tailing dam failure are not anticipated during the proposed three years plan period. However, the occurrence of flash flood due to unseasonal rain cannot be ruled out. Therefore emergency plan for quick evacuation in such situation will be kept ready. River banks will be regularly inspected to check bank failure and erosion.
During rainy seasons after first year of operation the flood level/ water level will be recorded particularly on the days of heavy downpour.
viii) Care and Maintenance during Temporary Discontinuance- In the case of temporary discontinuation or incomplete work due to court order or due to statutory requirements or any other unforeseen circumstances, a plan indicating measures of care, maintenances and monitoring of status of unplanned discontinues mining operation expected to re – open in near future will be provided. This will include status monitoring and maintenance with periodicity and objective.
If due to unforeseen reason, the mine need to be shut down temporarily, then adequate arrangement will be made to protect staff, workers and assets. Notice of temporary discontinuance in prescribed format shall be sent to the state Govt. and other govt. department of central govt.
38 J.P. BHATTACHARYA REG.NO. – RQP/RNC/134/2008/A OLMUNDA SAND MINE (PROPRIETOR- SAMIM KHAN)
b). Environmental Aspects
i) Mined out Land (river bed) and its Final Use- Sand will be mined from the river- bed which will be replenished naturally by the flow of river water and hence there will be no degradation.
ii) Air and Water Quality Management- Air and water pollution control measures will be taken to contain any likely air and water pollution. The effort will be made to maintain ambient air and water quality within the stipulated norms.
These have been dealt in detail in Environmental Management Chapter.
Monitoring of these parameters will be done at least for three months to one year after cessation of mining activities depending upon the total leasehold area, production rate and location of the site.
iii) Waste Management- There will be no generation of waste during sand mining. The sand bed is devoid of any top soil layer.
iv) Management of Sand Bed Topography- The undulations, voids, small dunes created during mining period will be smoothened by deploying manpower but the most of these will get transformed in to its almost original bed topography due to natural processes like river flow movement and surface run-offs. The mining scheme will ensure that the non mineable part of sand reserve is left intact.
v) Land Reclamation and Rehabilitation- No reclamation of land and rehabilitation will be required as this will take place through natural processes.
