1.2 Project Profile

Chettinad Cement is operating its Kilapaluvur Cement Plant near Ariyalur since 2009 and the existing production capacity of the Plant is 5.5 MTPA Cement. The Plant operations are in compliance with the conditions/norms stipulated in the Environmental Clearances awarded by the Ministry of Environment and Forests (MoEF) and Consents to Operate granted by Tamil Nadu Pollution Control Board (TNPCB).

Kilapaluvur Cement Plant requires limestone about 5.5 MTPA. Chettinad Cement has 10 Captive Mines in the Ariyalur Region which are supplying/going to supply about 3.305 MTPA limestone. In order to meet the additional limestone demand, Chettinad Cement has to open up the new Mine Blocks in Ariyalur area. Sendurai Limestone Mine is one of the mines to be opened and operated immediately for 0.33 MTPA Limestone & Marl production to cater the Cement Plant.

Chettinad Cement Sendurai Limestone Mine is a fresh Mine over an extent of 21.925 Ha owned by the Company in SF Nos. 110, 151,152,156,157,158,159, etc. in Sendurai Village, Sendurai Taluk, Ariyalur District of Tamil Nadu State (Fig. 1.1).

The Mining Lease (ML) area is located at 1.5 km in the east-northeast from Sendurai and is accessible from Ariyalur-Sendurai-Jeyankondam State Highway (SH) - 139. There is no Forest/Govt. Land involved as the Lease Area is Company owned Patta Land. There is also no Rehabilitation & Resettlement (R&R) issue due to the Proposal. There is no litigation/pending case against the proposal. Project Area does not fall in Critically Polluted Industrial Clusters listed by CPCB. There is no grass land in the ML Area vicinity.

The findings of baseline environmental status of the study area are summarized below : v The collected meteorological data during this season represented the local weather phenomena. v The monitored ambient air quality in the study area was found to be in compliance with the Revised National Ambient Air Quality (NAAQ) 24-hourly Norms of 60 ug PM2.5/m3, 100 ug PM10/m3, 80 ug 3 3 SO2/m and 80 ug NOx/m for Industrial, Residential, Rural and other areas. v Ambient equivalent noise levels (Leq) during day and night times were found to be well within the MoEF Norms. v The water quality of surface waters were found to be in compliance with CPCB Norms. The ground water quality was found to be in compliance with the IS:10500 Norms. v The soil in the study area would very well support vegetation after amending it suitably. v There is no Wild Life Sanctuary or National Park or Biosphere or Hotspots within the study area of 10 km. Domesticated animals and common fauna only exist in the study area. v The area is thinly populated and basic amenities are available almost in all villages.

Thus, there is adequate buffer for the proposed Project in the physical, biological and edaphic environments of the study area.

3.0 Anticipated Environmental Impact and Mitigation Measures

Any Project would create impact on the environment in two distinct phases : v Construction Phase which may be regarded as temporary & short term and v Operation Phase which would have long term effects.

The impacts have been assessed for the Project assuming that the pollution due to the existing industrial activities has already been covered under baseline environmental status and continue to remain same till the operation of the project.

Ensyscon & Amblabs, Chennai-78. Chettinad Cement Corporation Ltd. EC for Sendurai Limestone Mine, Ariyalur-Extent 21.925 Ha-Production 0.33 MTPA

The proposed Mine Project does not involve any Rehabilitation & Resettlement (R&R). Being a mine Project, it does not involve any major establishment or construction also. Thus, various impacts during the Operation Phase have been studied and discussed in the subsequent sections.

3.1 Land Use

Anticipated Impacts : An extent of 21.925 Ha, owned by the Company, will be under Industrial Use. There is no Forest/Govt. Land involved. It is barren site without any trees/plants. No township is proposed.

Top Soil generation from the mine is about 51,188 tons and the OB generation is about 5,11,875 tons. The Top red soil will be removed and used for Green Belt along the periphery, 50 m Safety Zone and for the afforestation in the backfilled area. The Over Burden, yellowish clay, will be stacked temporarily as dump in the area earmarked separately (OB Dump Dimension : 350 x 100 x 9 m).

The total excavated area shall be around 14.1 Ha at the end of mining operations. No reclamation/ rehabilitation plan has been envisaged during this Plan Period. Backfilling will start from the sixth year onwards in the exploited areas. It is proposed to back fill 1.6 Ha and the remaining mined out area (12.5 Ha) will be converted as an artificial pond/reservoir to harvest the rainwater. The Land Use pattern at different stages of mining are given in Table 3.1.

Table : 3.1 Land Use Pattern

At the End of Plan At the End of Mine’s Activities Period, Ha Life, Ha Mining pit 14.100 12.500 Back filled area 0.000 1.600 Waste dump - top soil / OB 2.150 0 Green belt 1.500 7.325 Haul road and allied services 0.500 0.500 Unused land 3.675 0 Total 21.925 21.925

Apart from the change in land use pattern within the Lease area, there will not be any adverse impact on the land use of the surrounding area. The drilling and blasting activities will be associated with ground vibrations.

Mitigating Measures : v Blasting shall be carried out using optimum burden, charge and milli second delay detonators. v Ground vibrations shall be continuously monitored during Blastings using a Minimate Seismograph. v Coco filters shall be used (geo textile matting) at the dump slopes to arrest/control soil erosion.

Ensyscon & Amblabs, Chennai-78. Chettinad Cement Corporation Ltd. EC for Sendurai Limestone Mine, Ariyalur-Extent 21.925 Ha-Production 0.33 MTPA

v Construction/maintenance of garland drains at foot of dump and around mine areas shall be done. Coco filters shall also be used to arrest silt being carried to water bodies/natural drains. v Earthen banks will be provided on non-operating side of dumps to arrest wash-offs. v Saplings will also be planted along the foot and unused slopes to arrest / prevent erosion. v After the mine reaches the ultimate depth, developmental wastes and rejects stacked in the earmarked locations shall be backfilled and the topsoil shall be spread as top capping in the reclaimed areas and afforested. v The balance parts of excavated mine pits shall be converted into a water reservoir. The water reservoir would be used for pisciculture and agricultural activiities for the benefit of nearby villagers. Local Women Self Help Groups & Panchayats would be permitted to maintain and enjoy the benefits.

3.2 Traffic Volume

Anticipated Impacts : The proposed production from this Mine is 0.33 MTPA @ 1100 Tons/day. SH-139 and SH-27 are the transport routes from the mine to Kilapaluvur Cement Plant through Ariyalur Bypass. No village road will be used for the transportation of limestone. The proposed Project near Sendurai is on the State Highway SH-139. The existing traffic volume in the Project vicinity was found to be 831 PCU/day. In the Post-Project Scenario, there will be an addition of 131 vehicles (256 PCU/day) to the existing traffic in the SH-139. However, the net increase (cumulative) will be 194 PCU/day only. The existing 2/4 Lane Highways and Ariyalur Bypass Road are adequate to handle the proposed addition of traffic volume. Adequate parkings are also proposed at the mine. Facilities for drivers (rest room, toilet, etc.) will also be provided.

Mitigating Measures : v Security Guards at the Highway-Mine Road Junction to handle the inward and outward vehicles from the mine to Highway. v Restriction of Truck parking in the Highway. v Green Belt with thick foliage along the haul road. v Restriction of over loading. v Speed restrictions. v Limestone Tippers to be fully covered with Tarpaulin. v Regular and preventive maintenance of transport vehicles. v Compliance to ‘Pollution under Control’ Certification.

3.3 Fugitive Emissions

Anticipated Impacts : The drilling, blasting, loading and transporting activities would generate both fugitive dust emissions and smoke from HEM Machineries/Equipments and Tippers. Quantification of particulate emissions has been carried out by the emission factor technique. Fugitive emissions have been predicted by using standard equations given in “Indian Mine and Engineering Journal” and suggested by USEPA (Emission Factors as referred in AP-42) for mining & allied activities.

Prediction Modelling : Prediction of ground level concentrations (GLC’s) has been made by Industrial Source Complex Short Term (ISCST3) Model for Area Source. The model uses rural dispersion and

Ensyscon & Amblabs, Chennai-78. Chettinad Cement Corporation Ltd. EC for Sendurai Limestone Mine, Ariyalur-Extent 21.925 Ha-Production 0.33 MTPA

regulatory defaults options as per guidelines on air quality models (PROBES/70/1997-1998). The model assumes receptors on flat terrain.

The maximum incremental GLCs for PM at the mine is 16.13 ug/m3. The predicted GLCs are superimposed on the baseline concentrations monitored to arrive at the likely resultant concentrations due to the project. The cumulative concentrations (baseline + incremental) after implementation of the project are given in Table 3.2. Table : 3.2 Predicted GLCs – PM10

Average Incremental Resultant PM10, NAAQ Norm, Available Name of the Location 3 3 3 3 PM10, ug/m PM, ug/m ug/m ug/m Buffer, % A1-ML Area 19.0 16.13 35.13 64.87 A2-Sendurai 36.7 7.92 44.62 55.38 A3-Viluppanakurichi 23.4 0.06 23.46 76.54 A4-Nallampalayam 20.1 0 20.10 79.90 A5-Rayampuram 29.3 0 29.30 70.70 A6-Nallanayagapuram 18.5 6.57 25.07 74.93 100 A7-Periyakurichi 27.5 0 27.50 72.50 A8-Kudikkadu 21.3 0 21.30 78.70 A9-Virakkan 15.5 0 15.50 84.50 A10-Anandavadi 34.3 0 34.30 65.70 A11-Chokkanathapuram 20.9 0.49 21.39 78.61 A12-Tular 25.8 0 25.80 74.20

As per the prediction, Adequate Buffer (55.38-84.50%) for PM10 exists in the Air Environment for the proposed Mine Project. Other pollutants SO2 and NOx emissions due to mining activities will be insignificant.

Mitigating Measures :

Fugitive Dust generation in the mine areas shall be controlled by : v Drilling with dust extractors and use of water jet for dousing the cuttings (wet drilling). v Well designed blasting by effective stemming and use of milli second delay detonators. v Avoiding blasting during high wind periods. v Water sprinkling on the dust generation points, haul roads, etc. v Wetting of haul roads periodically. v Green belt development along the periphery, haul roads, waste dumps, etc. v Avoiding over loading of trailers/tippers. v Covering of trailers/tippers with tarpaulin during transportation. v Periodical maintenance of trucks/trailers. v Periodical check up of vehicles for ‘Emission Under Control’ measures. v Periodical maintenance and replacement of worn out accessories in the mine equipments.

Ensyscon & Amblabs, Chennai-78. Chettinad Cement Corporation Ltd. EC for Sendurai Limestone Mine, Ariyalur-Extent 21.925 Ha-Production 0.33 MTPA

3.4 Noise & Vibration

Anticipated Impacts : The major noise source from the mines is drilling and blasting. The noise levels due to the Mine Equipment’ operations would be maintained at <85 db(A) at a distance of 1.5 m from the sources. In general, noise generated by these sources will be within the limit of 90 dB(A) prescribed by Director General of Mines Safety (DGMS), Dhanbad. The work force will be exposed to <85 dB(A) levels during the 8-hours Shift.

Ambient Noise level at the boundaries would be maintained <55 dB(A) during day times and <45 dB(A) during night times, well within the MoEF Norms for Residential and Rural Areas.

During Blasting, for normal charge, the Peak Particulate Velocity (PPV) will be much lower than 12.5 mm/sec fixed for for Industrial Zones (mines) and the noise levels will be < 90 dB(A).

Mitigating Measures : v Deploying mining equipments shalll be with in-built mechanism for reducing noise. v Provision of silencers to modulate the noise generated by the machines. v Blasting shall be carried out using optimum burden, charge and milli second delay detonators. v Milli second delay detonators shall be used to give sufficient delay between holes so that number of holes blasted at a time is minimized, resulting in reduced noise and vibration. v Ground vibrations shall be continuously monitored during Blastings using a Minimate Seismograph. v For normal charge, the Peak Particulate Velocity (PPV), shall be well with in the limit value of 12.5 mm/sec fixed for mines. v Providing sound proof operator's cabin of equipments. v Provision of ear muffs/ear plugs to the Workers in higher noise zones. v Green Belt with thick foliage along roads and around lease boundary to act as acoustic barriers.

3.5 Water Environment

The water table in the ML area fluctuates from 20 m below ground level (bgl) to 25 m bgl during postmonsoon and pre-monsoon seasons respectively. Since it is proposed to mine ultimately upto a level of 15.5 m bgl, the mine workings will not intersect the water table.

Mine operations require about 20 m3/day fresh water for domestic, dust control and green belt development which will be met out from the borewell at the mine area and mine pit seepage water.

As per PWD GO (Ms) No. 52 dated 02.03.2012, Sendurai Block falls in Safe Category and Central Ground Water Board (CGWB) permits 100 KLD ground water drawl in Safe area for industrial use with out its NOC (CGWA Circular No. 21-4/Guidelines/CGWA/2009-832 dated 14/10/2009).

There is no trade effluent from the Mine. Only, domestic sewage generation will of 2.5 m3/day will be generated which will be biologically treated in a Septic Tank followed by Dispersion Trench.

Ensyscon & Amblabs, Chennai-78. Chettinad Cement Corporation Ltd. EC for Sendurai Limestone Mine, Ariyalur-Extent 21.925 Ha-Production 0.33 MTPA

Proposed Mitigating Measures : v Maintaining a gradient of 1o or 2o on the bench floors (for drainage of water) and construction of water drains to prevent soil erosion and uncontrolled descent of water. v Construction and maintenance of garland drains around mines area with proper gradients to prevent rain water descent into active mine areas. v Earthen banks will be provided on non-operating side of dumps to arrest wash-off. Saplings will also be planted along the foot and unused slopes to arrest / prevent erosion. v Mine Seepage/Drainage : During non-monsoon periods, 25-30 m3/day seepage water will be collected and allowed for the suspended solids settlement in the lowest bench. The mine pit water will be utilized for the mine water demand @ 20 m3/day. v Pit Water Management during the monsoon periods : The Region receives 50% of total rainfall during Northeast Monsoon periods (October-Novemeber months) with 20-25 rainy days. Remaining 50% of rainfall occurs during Southwest Monsoon and Transitional Periods with 30-40 rainy days. In total, 55-65 rainy days are there. The maximum intensity recorded was 35 mm/hr in a day. With that intensity of rainfall, the mine pit (400 x 350 m) may receive about 4,900 m3 water in a day (worst case) which will be pumped out by a pump of 20 HP capacity to the nearby natural drain. v Water Reservoir : In the Conceptual Stage, the total excavated area shall be around 14.1 Ha. It is proposed to back fill 1.6 Ha and the remaining mined out area of 12.5 Ha will be converted as an artificial pond/reservoir to harvest the rainwater. With the normal rainfall of 1200 mm, the mined out pit will store about 1,50,000 cu.m per annum which could be used as a water source for the neighboring villagers.

3.6 Biological Environment

Anticipated impacts : The Mine area is predominantly barren and does not warrant any cutting of trees, clearing bushes, etc. Thus, there will not be any significant impact on the flora-fauna of the area. Due to the proposed mitigating measures of mine pit water, the impact of mining activity on nearby water bodies (fishery resources) and agricultural lands will be minimum or nil. There is no habitat fragmentation or blocking of migratory corridors due to project activities since there is no wild life movement or migratory birds movement.

There is no loss of forest cover due to the Project and hence there is no need of compensatory afforestation. However, to have more green cover, an effective green belt will be developed along the boundaries, haul roads, etc. Afforestation in the reclaimed area will also be undertaken.

There is no rare/endemic/endangered species of flora and fauna surveyed in the mine vicinity or study area and thus, no Conservation Plan is envisaged.

Mitigating Measures : v Green Belt with native species shall be developed all along the boundaries, haul roads, waste dumps, etc. v Stabilization of dumps by coco filters and proper vegetation cover shall be done. v Garland drains shall be provided around the dump to arrest soil erosion. v Afforestation in the reclaimed areas, as proposed, shall be undertaken.
