3.3 Give review of earlier approved proposal (if any) in respect of exploration, excavation, reclamation etc.

3.3.1(a):Exploration:

Director of Geology & Mining along with TANCEM carried out systematic exploration of the area in the year 1984-85. By exploratory core & Noncore boreholes were drilled covering almost the entire strike length. The drill holes were drilled regular grid pattern.

The geological mapping was done on the topographic plan, which is the base map, prepared on a scale of 1: 4000, with a contour interval of 1 meter. .

Diamond drill holes and Wagon drill holes were placed at closer intervals (i.e.) 400 M and 200M respectively. The bore holes within the lease area were drilled in grid pattern running NE-SW direction. Geological cross sections were prepared, on a scale of 1: 2000, along -the dip direction, joining the diamond drill holes drilled along the grid line (Please refer Plate-3 & 3a).

The details of drilling, sampling and other exploration done in the area of GO MS 624 are given below.

No Details of Exploration Grid interval Remarks Work 01 Diamond drilling (a) No. of holes completed 27 400 Mtrs Location of (b) Metreage 845.75 BH /WDH 02 Wagon drilling are shown (a) No. of holes completed 19 400 Mtrs in the 206 Geological (b) Metreage Plan-Plate- 3 03 Total No. of samples 850 collected The exploration of the area reveals the presence of limestone and associated litho units of varying thickness throughout the area.

During the scheme period 2016-17 to 2020-2021, the exploration proposals has been made in the regular grid and will be put in between the earlier bore holes to know the deposit and further enhancement of reserves. As per the discussions had the company officials, at the present period of scheme of mining the company has proposed the total of 20 nos. coring bore holes from the year 2017-18 to 2020-21 at the rate of 5 bore holes in every proposal period as per the UNFC guidelines.

During scheme mining period, the production was commenced in the year 2016-17 to tune of 260000 tons only. There is no production from this lease due to local social problem by previous land owners and demanding their permanent employment with the company. Due to employment / agitation made by land given people and local villagers to the company, there was no production during the year 2016-17 and at the end of year 2017-18 in the month of February second 2018; the company has started mining operation.

3.3.1C: Exploitation of Mineral:

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 12

M/s Tamilnadu Cements Corporation Ltd.

In the previous approved scheme of mining, the production was projected as 2.60 lakh Tons per annum for five year period from the year 2016-17 to 2020-21.

It may be seen from above that production could not be achieved as per the targeted production of the previous scheme period year 2016-17 and 2017-18, are due to the following reasons

---Cost of Mining & Transportation ---Administrative issues of M/s. TANCEM due to the local social problem by previous land owners and demanding their permanent employment with the company. Due to employment / agitation made by land given people and local villagers to the company, there was no production during the year 2016-17 and at the end of year 2017-18 in the month of February second 2018; the company has started mining operation. .

Cut-off grade

The Mining Lease area is located in the state of Tamil nadu the threshold value and cut off grade of limestone as per circular 3/2010 of IBM (Indian Bureau of Mines) is given below:

Limiting Values CaO% MgO% SiO2 Threshold values 35.00 4.00 18.00 Cut Off Grades 35.00 1.00 18.00

Keeping in view the exploitation of limestone for the manufacture of cement, the process parameters of LSF (Lime Saturation Factor), SM (Silica Modulus) and AM (Alumina Modulus) should also be satisfied from the material being fed to the plant. The expected range of the as above parameters is as follows:

Parameters Range

LSF 0-85 – 1.10 SM 2.20 – 2.80 AM 1.20 – 2.50 From the grade of limestone given above it can be observed that the limestone from this leasehold satisfied all the requisite parameters required for manufacture of cement.

M/s Tamilnadu Cements Corporation Ltd.

As per the norms prescribed by NCBM (National council for Cement and Building Materials) the broad chemical specifications of cement grade ROM limestone are as follows:

CaO%

Acceptable range for manufacture of OPC 44-52

Limiting values taking into consideration Min. 40 type of cements, scope of beneficiation and blending

Thus, limestone with at least 44% CaO is required in the ROM for manufacture of cement and limestone above 40% CaO can be used if beneficiation is provided or higher grade limestone is available which can be blended to upgrade the lower grade limestone upto 44% CaO. The quality of available high grade ore in Anandavadi limestone is of 47.5% CaO content and having less Fe2 O3 & MgO, and this can be blended well with the Kallankurichi deposit limestone materials which are having high Fe2 O3 and less SiO2. The present blending technique and raw mix design is given below. During the enhancement of limestone production and Cement capacity of plant, the blending technique and raw mix design will be modified according to the available grade of limestone and limestone from new mining leases in future.

Grade of Limestone:

The limestone is yellow color fine to medium grain bedded in nature and fossiliferous. The marl is pale yellow and powder in nature overlained by red soil. The purity of limestone is about 70 to 80% TCO3 with little MgCO3. The SiO2 content is ranging from 10-18% in the entire mining area.

The variation in the chemical behavior of this limestone & marl is summarized below

The reservoir will have an enough potential to store water. The water in the reservoir thus located shall improve bore well irrigation.

The undisturbed virgin lease area along the mining lease boundary shall be utilized for agricultural purposes by developing the area with eucalyptus and causurina plants with co ordination of Forest department and TNPL. This work shall be done after the cessation of mining operations.

This aspect has been considered in detail. Accordingly conceptual mining plan is drawn. There is adequate space for dumping waste rock. After the mine reaches the ultimate depth waste stacked in the ear marked location will be spread as top capping in the reclaimed area to improve the growth of vegetation.

The total quantity of top soil black cotton soil material has been stacked all along the mining lease boundary and in the eisting top soil dump location area earmarked in the plated no. 6A to 6C

Proposed Top soil and waste dump configurations are shown in the year wise and developmental plans and sections in plate nos. 6A to 6C.

Stabilization and vegetation of dumps During the previous years of operation, the quantity of topsoil / waste rock dumped is meager and with minimum height of 1 metre to 1.5 metre there will not be possibility for slope instability. Hence the question of vegetation of dumps does not arise. Moreover, the dumped topsoil during mining operation will be removed and used for afforestation purposes.

Measures to control erosion / sedimentation There is no any major nallahs nearby the workings. So there will not be any problem regarding erosion. Moreover there is no major dumps, which may be exposed to erosion, and hence no sedimentation also. If at all the water course filled with sediments, it will be cleared every year after monsoon. Only the surface wafer, which is a source of erosion, is diverted by forming the bunds.

(ii) Water regime

The Nallah is passing across the lease area and flowing from NNE to SW of the lease area. It drains the area and joins the local water body in the south and western portion of the ML area. The Nallah is not perennial. It is dry during the major part of the year but is subject to occasional flash floods.

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 45

M/s Tamilnadu Cements Corporation Ltd.

The ground water table is about 30 to 35 metres below the ground during the summer and it raises during rainy season.

(iii) Flora & Fauna:

Flora: The area adjacent to the mining lease is occupied by vegetation and other species. In the buffer-zone area of five kilometers, we find neem, babul etc., on bunds. Natural vegetation like grasses and wild shrubs grow during the monsoon, which is useful for grazing and in the summer, they dry out. Density of flora will be around 100 trees / hectare.

Fauna: The fauna that is obtained within the buffer zone are common varieties like foxes, jackals, mongoose and rats etc. In the amphibian and reptile category monitor lizard, cobra, viper, krait, chameleons are found. The insects are honey bee, wasp, beetle, termites, bugs, mosquitoes, scorpion, red ants etc.

The fauna found in the area are of common variety and thus no endangered species are found in the study area.

Base line data generation for air, noise level, ground vibration will be discussed in detail after the completion of one season monitoring. Presently the various environmental parameters are discussed based on the available data.

(iv) Quality of air:

Generally the dust level in the air is kept within the limit. The maximum concentration of air pollutants at different- stations during the study indicates that the highest 24 hour concentration of S P.M. was 260.6mg/m3 at TAI Station (Anandavadi village) and well within the CPCB limits .

3 The maximum 24 hour concentration of SO2 was 7.6 mg/m at station TA4 (Sendurai) and is well within the prescribed limits of CPCB (80mg/m3).

3 Similarly the maximum 24 hour concentration of NOX was 16.8 mg/m at station TA2 (Maruvathur) and is well within the prescribed CPCB limits (120 mg/m3).

Hence there will not be any bad impact on Air quality by mining, to the entire life of the mine.

In case of source samples, the SPM level recorded has been a maximum of 1659.6.50 micrograms /m3 near haulage road (source sample) requiring suitable management measures. The CO level in the ambient air samples was found to be below detecting level.

(v) Noise level:

Noise level is kept under check. Adequate measures will be taken up to control the noise level and also to provide appliances to the operators to avoid noise pollution if any.

The maximum and average of this noise levels in the 0 - 3 KM zone are 90 dB(A) and 74 dB(A) respectively. Whereas in 3-8 KM zone the same have been reported to be 71 dB(A) and 52 dB(A) respectively. In the 8-10 KM zone the maximum noise level recorded is 68 dB(A) and the average is 51 dB(A).

Hence there will not be any damage risk for hearing loss, by the mining activities, upto the mine life period.

M/s Tamilnadu Cements Corporation Ltd.

To reduce the noise level efforts will be made by proper maintenance schedule, placement of compressors away from the workers. However, in addition to this, earmuffs are also being provided to the workers to prevent them from the noisy environment.

(vi)Ground vibrations:

Three number of blasts have been conducted at source area from close distances and found that the peak particle velocities were found to be less than 3mm / sec. The readings are taken from the blast site at different distance in the three blasts. During the first blast, around 600 kgs of explosives were blasted with a charge per delay of 202 kgs, the PPV value was measured at a distance of 500m from the blasting site, which showed a value of 1.5 mm/sec. During the second and third blast, the ppv values were measured at a distance of 150m and 75m respectively, in which we recorded a PPV value of 1.5 and 2.9 mm/sec.

Ground vibrations were measured near the mine site at different directions at the time of blasting and readings were found to be very less.All the mining area is isolated, and no residential structures are nearby. Due to ground vibrations while blasting, nearby dwellings will not be affected because of very low particle velocity.

Protective measures for ground vibrations / airblast

Ground vibration is an important consideration, so that public should not be affected. The following measures are taken to minimize ground vibrations and air blast by blasting.

1. A delay interval of 25 milliseconds, between holes is maintained using delay detonators. 2. Individual delays for each hole is used with card relays.

3. We will minimize the use of detonating fuse within the hole and other portions will be covered with drill cuttings and there will not be air blast.

4. Peak particle velocity will be kept very low, by using non-el-system as a special case.

5. For larger blasts, sequential timer will be used in the blasting operations to avoid noise and vibration.

6. Proper spacing and burden is maintained according to the bench heights to control blasting with low particle velocity and low noise.

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 48

M/s Tamilnadu Cements Corporation Ltd.

7. Adequate care is taken to minimize the ground vibration by proper selection and usage of explosive depending upon the strata to be blasted.

However, displacement due to blasting was measured using a vibration meter at a distance of 500 m from the mine and the displacement noticed was only 0.2 micron which is very minimal which will not cause any damage.

MPN Coliform (per 100 ml) values have been observed within limit.

From the above results, the prescribed limit of IS 10500, it is found that ground water of the study area is fit for drinking purposes as alternate source.

There would not be any toxic effluent from mine hence there in no need for any treatment of water from mine.

Control measures to be adopted are

The peripheral bunds will help that soils is not carried away by storm water. Stabilization of bund slope to prevent erosion and this shall be done by providing dense plantation along the bund slopes.

During dewatering operations the pumped out water will be let out in the nearby natural courses.

(viii) Climatic conditions

A meteorological station was set up in all three season to collect micro meteorological data for the area.

The average annual rain fall in this area is about 900 mm. The area receives maximum rainfall during N.E. Monsoon (i.e.) between October to December and precipitation also occur during S.W. monsoon between July and September.

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 50

M/s Tamilnadu Cements Corporation Ltd.

The rains are not generally heavy enough to hamper mining operations for more than one or two days at a time. Ho disastrous floods have been recorded in this area. The maximum temperature in summer months is 40° C. In the winter months (December to February) the minimum ternperature would be about 300 C. Cyclone and storms are rare in this area. The main wind directions are as follows. Winds are mainly from directions between North and North East from November to February. In March winds are mostly from directions North East and South East, to the morning and afternoon they are either Northerly to North Easterly or Southerly to South Easterly. During April to October winds blow mostly from directions between South and South Western in the morning, in the afternoons they are between South West and South East.

The area is well outside the known earthquake belt of the country and no earthquakes or sympathetic shocks have been reported since historical times.

(ix) Human settlements:

The mining lease area is surrounded by few small villages. The main occupation of the people in this part is agriculture. The lands in these areas are very fertile. Besides agriculture there are no major industries. .Rehabilitation Within the Mine lease area, there is no a village or human settlement. Hence there is no question of any evacuation and resettlement of people elsewhere. . Socio Economic Studies It is well known fact, that industrialization will affect directly or indirectly the life styles, social structure and economics of the persons who are living in the region. A study of the existing baseline date on these aspects will help to force the impact of mining in future. For this study the area has been divided into 2 zones namely core and buffer, while the 5KMs belt around the mine lease area constituted the core zone the area up to 10 Kms distance from the periphery of the lease has been considered as buffer zone. Baseline data and socioeconomic environment in the core and buffer zone were combined from the senses. The data covers various constituents such as demo graphs, literacy, employment, land classification, availability of educational, medical and communication facilities etc.

Any mining operation is likely to alter the already existing topography. Scheduled reclamation of the mined out areas will eventually represent a better landscape with even topography, which would be amenable for farming etc. b) Aesthetic Environment and Tourist Spots (if any)

The Mining lease area neither endowed with environmentally aesthetic attributes not is an attractive place for tourists. c) Soil and Land use Pattern

Opencast mechanized mining operations in this area would not cause discernible changes in the soil characteristics since mining operations will not result in any kind of toxic effluents nor would there be any solid waste generation.

The existing land use pattern is mainly cultivation for rotational/seasonal crop harvest. In the M.L. area, most of the area is agricultural land and the remaining part comprises of grazing lands and scrub jungle. Most of the plants are armed with spines and hooks. The prevailing land use pattern in the post-mining period would not altogether get altered. Novel and extensive schemes of afforestation will be implemented so as to minimize the effect of current land use. d) Agriculture

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 53

M/s Tamilnadu Cements Corporation Ltd.

The proposed mining methods will not cause any harm to the agricultural field in the surroundings.

With the commencement of mining operations employment (both direct and indirect) opportunities will inherently force a change in the occupational structure partially. Consequently with increased economic status, modernized agricultural practices would be adopted which will result in not only better crop yield, but also reduce the pressure on particular operation.

Additionally, the wastelands and fallow lands upon mining and suitable reclamation will result in beneficial rehabilitation of the derelict lands. Emphasis will be on restoration of mined out lands to agricultural practices. e) Forest

The Mining lease area does not include any forest area. f) Flora and Fauna

The area under mining lease is not a habitat for wild life or bird sanctuary etc. Therefore mining would not cause any effect on existing flora and fauna. There is no rare/endangered species of flora in the area. Mining operations will not involve any felling of trees etc. as most of the area selected for mine working is devoid of trees/plants etc. There is no wild life sanctuary in the vicinity of mining lease area. So no rare/endangered or wild species is likely to be affected by the mining project.

AIR:

A number of activities have an impact of ambient air quality of the area. These includes industries,

domestic fuel consumption, traffic emission etc. Major pollutants are SPM, Nox and So2. The main

source of air pollutant in SPM is mining activities. The generation of Nox and So2 results obtained are well within the limits prescribed by CPCB for areas meant for industrial use.

Air pollution impact analysis is of prime concern. Dust is a particulate contaminant suspended in the atmosphere. The upper size limit of dust particles is governed by gravitational effects. While the distinction between the respirable and non respirable dust is scientifically valid it is clear that both sizes can impair lung functions when inhaled over a time.

Deployment of diesel powered equipment for mining may produce emissions that are known to be hazardous, viz unburnt hydrocarbons, oxides of nitrogen, particulates, phynols, aldehydes, oxides

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 54

M/s Tamilnadu Cements Corporation Ltd.

of sulphur, trace elements, smoke and hydrocarbons. These pollutants are known to cause respiratory ailments.

Use of protective equipments to reduce the exposure of personnel to excessive concentrations of dust, dust suppressive techniques along haul tracks and drilling sites are practiced to minimize negative impacts.

Ambient air quality Monitoring was carried out for summer season (April, May and June). The parameters selected for analyzing ambient air quality status were Respirable Particulate Matter

(RPM), Suspended Particulate Matter (SPM) Oxides of Nitrogen (Nox), Sulphur diaoxide (SO2). A summary of ambient quality monitoring results for 24 hours average concentration are given below:

Locations Values SPM RPM SO2 NOx µg/m3 µg/m3 µg/m3 µg/m3 Anandavadi Min 67.60 33.740 7.00 6.00 lease site Max 74.20 41.30 12.00 10.00 Mean 71.57 38.98 9.63 8.13

Control Measures for Air Quality / Dust Suppression The main activities for air pollution are drilling, Blasting, loading, unloading, transportation and heavy duty mobile equipments. Suppression measures like water spraying along haul road, roadside plantation to provide canopy of foliage and regular use of water ejecting system to dampen and control the dust during the course of drilling will be undertaken.

The proposed measures to control air quality within the limits are detailed below,

Mobile equipments Dust emanated due to the movement of equipments is generally suppressed by the following ways:

Surfacing of internal roads.

Dust suppression by water sprays Dust generated in the mines will be suppressed by sprinkling water on haul roads with the help of mobile water tanker with sprinkling arrangement. As there is not much of water seepage and accumulation in the pits, permanent pipe line connection for spraying water on haul road for dust suppression cannot be carried out immediately. However your advice & suggestion will be

considered in future.

Rows of trees would be planted ii) WATER ENVIRONMENT:

a) Surface Water:

The ground water table is about 15 to 20 metres below the ground during the summer and it raises during rainy season.

b) Ground Water

Ground water is the main source in this area, apart from rain in the monsoon period. The water table is intersected 15 to 20 meters the surface. The ground water will be collected in the sump for the deposition of solid particles. Once the suspended particles are deposited it will be pumped out for domestic purpose, dust suppression system, gardening and Afforestation purpose. The excess water only will be pumped out to the nalla /closer water bodies – pond after the deposition of solid particles. There are no toxic elements found in the sump water.

The water table is found at a depth of 15metres in rainy season and at 20m in dry season. To cope up with storm water and seepage water, an energy efficient electrical pump of 20H.P capacity will be installed and the discharge will be let-out in the nallah/Pond. Garland drains will be made all along the periphery of dumpsites to prevent the water carrying the wash-offs from the dumps and topsoil yard entering into the mines. The water collected in the garland drains will flow towards a settling tank formed near by the dumpsite. The water will be allowed to settle the wash offs from the dumps in the settling tank and pure & clear water will be utilized for afforestation purposes and for wetting of haul roads to arrest the dust generation. (v) Noise level: Noise level is kept under check. Adequate measures will be taken up to control the noise level and also to provide appliances to the operators to avoid noise pollution if any.

The maximum and average of this noise levels in the 0 - 3 KM zone are 90 dB(A) and 74 dB(A) respectively. Whereas in 3-8 KM zone the same have been reported to be 71 dB(A) and 52 dB(A)

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 56

M/s Tamilnadu Cements Corporation Ltd.

respectively. In the 8-10 KM zone the maximum noise level recorded is 68 dB(A) and the average is 51 dB(A).

Hence there will not be any damage risk for hearing loss, by the mining activities, upto the mine life period.

8.3 Progressive reclamation Plan:

In the preceding chapter, an attempt was made to assess the likely impact on the environment due to various mining activities. This chapter describes the scheme for environmental management, the proposed abatement measures to minimize the likely environmental degradation that may be caused due to the mining operations at proposed Mining Project.

Considering the scale and methodology of mining operations in the project area as discussed earlier, no significant environmental degradation is expected. The micro level eco system and socio economic setup of the villages is likely to improve. Environmental control measures and techniques are discussed below to mitigate any adverse effect owing to the mining activities.

8.3.1. Mined-Out Land:

The total excavated area shall be around 60.685 Ha at the end of mining operations. It is proposed to convert the mined out area as an artificial pond to store rainwater and as well as part of the area will be refilled and subsequently afforested. The area is arid and has a low about 900mm/yr. Therefore the water stored from rainfall could be used as reservoir in the locality helping the neighboring villagers. The reservoir will have an enough potential to store water. The water in the reservoir thus located shall improve bore well irrigation.

The undisturbed virgin lease area along the mining lease boundary shall be utilized for agricultural purposes by developing the area with guava, straw berry, fig fruit plants etc. This work shall be done after the cessation of mining operations.

Justification Artificial Pond to Store Rain Water: The sub-surface of the area is composed of hard rocky strata. So the rainwater is not directly and effectively absorbed into the ground. Since no major water resources / reservoirs / lakes / ponds etc, are present in the area, if we fully reclaim the mined out pits we would completely loose the entire rainwater instead of being harvested in the mined out pits thereby increasing the level of the water table in the area will get increased.

Therefore, by proposing to utilize the mined out pits as water reservoirs, after entire mining operations gets completed, we would be able to serve the following purposes:

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 62

M/s Tamilnadu Cements Corporation Ltd.

1) Sustain the water resources for the drought prone area of local villages. 2) Increase the level of water table in the adjacent area. 3) To meet the drinking water requirement of local villagers. 4) To afforestate the non-mining leases areas (earmarked for afforestation) with the Stored water from these pits.

Therefore, considering the above facts, we propose not to reclaim the mined out pits after entire mining is completed instead we would utilize them as water reservoirs which would be the need of the prevailing hydrological atmosphere in the mining lease area.

8.3.2 Topsoil Management:

During the three year modification period no topsoil will be generated and it will be in meager quantity will be stacked all along the safety barriers of the lease area, and it will be utilized for the afforestation purposes.separately in the 50M safety zone area along the odai. The average thickness of the top soil is varying in thickness 1 to 0.5M in the mining lease area for mining. The upper layer of top soil, which is oxidized and contains organic matter will be stripped and used for spreading over the slopes of the peripheral bund to facilitate revegetation and also for tree plantation over areas beyond the peripheral bund. Excess quantity of top soil remaining will be stacked separately in a dump yard for the above stated purpose. The slopes of the dumpsites

Modifications to the Approved Mining Plan of Anandavadi Limestone Mines (G.O.624, Ext.110.68.5Ha.) 63

M/s Tamilnadu Cements Corporation Ltd.

will be terraced with grasses, legumes etc to arrest soil crossing to a great extent. The soil from this dump yard and shall be rehandle and spread over the backfilled areas, once backfilling of the mines out area commences.

During the modification period to plant about 1500 Nos. of saplings all along the boundary to cover an area of 2.50.0 Ha and the survival rate of plantation is only 80%.
