CHAPTER -1

INTRODUCTION 1.0 GENERAL

Coal is an important infra-structural input and a dominant source of energy in India accounting for 54% of the country’s primary energy needs. The quality of coal plays an important role in environmental aspects during its use especially in power plants. Due to drift origin of Indian coal, ash content is quite high and coal seams have dirt bands of carbonaceous nature. High ash content in coal causes environmental pollution apart from reducing plant efficiency and adding the cost of coal transportation per unit calorific value. Further ash disposal is itself a difficult task with adverse environmental impacts, MoEF Gazette Notification, G.S.R. 02 (E) dated January 02, 2014 on coal supply to power plants located between 500-749 KM, 750-1000 KM shall be supplied with and shall use raw or blended or beneficiated coal with ash content not exceeding 34 % on quarterly average basis w.e.f June 05, 2016 and January 01, 2015 respectively while power plants located beyond 1000 kms from pit head shall be supplied with and use raw or blended or beneficiated coal with ash content not exceeding thirty four percent on quarterly average basis with immediate effect (i.e. Jan 02, 2014). Thus it is imperative that coal is beneficiated before use not only for value addition but also as environmental mitigation measures. A review meeting was taken by Honourable Minister of State (Coal) in January 2007 at CIL (HQ), Kolkata. In the review meeting, Coal India Limited (CIL) decided that all opencast mines with an annual capacity of 2.5 MTY or more, not linked to any pithead power house, should have provision for setting up coal washery with state-of-art technology. These proposed washeries are to be set up on Build, Operate & Maintain (BOM) concept. Keeping in view the above decision, MCL has intended to install 4 nos. of washeries in Ib Valley & Talcher Coalfields. Accordingly, MCL awarded the job for preparation of CR (Conceptual Report) for setting up of Hingula Washery at Talcher Coalfield on Build, Operate & Maintain basis to M/s Central Mine Planning & Design Institute Ltd. (CMPDI) vide letter no. MCL/ HQ/ 3206/ CP&P dtd 19.02.08. Thereafter, in the review meeting with Director (T), CIL held on 08.08.2008 at Kolkata it was discussed and agreed by all concerned present in the meeting that to expedite the works for setting up of coal washeries.

1.1 BRIEF DESCRIPTION OF THE PROJECT

The proposed Hingula coal washery will be located in the lease hold area of Balram OCP of Hingula area of MCL and its capacity shall be 10.0 MTY. The proposed project will receive coal from of Hingula-II expansion OCP of Hingula Area, MCL. The raw coal ash content of Hingula-II expansion OCP is in the range of 38.5 ± 4%. This ash content is proposed to be reduced to 33.5 ± 0.5% after washing in Hingula Washery for use in thermal power stations. It is planned for two product namely clean and reject. Washed coal shall be transported from Hingula washery to the silo (4000t) near railway siding by 2x2000 TPH covered conveyor belts of length 400m. The reject from the washery shall be to be transported from washery to reject site (area 10ha) by

covered conveyor belt of length about 760m. In the 155th meeting of Board of Directors of MCL held on 05.022014, the Board approved the sale of rejects from Hingula washery of MCL either through e-auction or MOU route. This was in line with the 75th meeting of CMDs held on 07.05.2013 wherein it was decided that EOI shall be floated to sell the reject from the proposed washeries. The proposed washery shall be set up on Build, Operate & Maintain (BOM) concept. Build, Operate & Maintain (BOM)” concept refers to the system in which finance for setting up of plant will be made available by CIL/ MCL to the selected bidder as in the case of turnkey basis. The scheme envisages planning, design & engineering, selection of necessary equipment & machinery, procurement, delivery, erection/ installation, testing, successful commissioning of coal washing plant including PGT with two years’ critical spares and all allied activities as well as its subsequent operation & maintenance for supply of washed coal of requisite quality at the designated delivery places and disposal of washery rejects on BOM concept. Freedom of selection of efficient, cost effective and state of art technologies lies with the BOM operator. The BOM operator will be responsible to produce washed power coal with the quality specification laid down by MCL. However, ownership of raw coal fed to the washery & products of washery shall lie with MCL. BOM operator will be paid washing charges as per mutually agreed terms & conditions for operating & maintaining the washery till the entire contract period. The contract period for operation and maintenance for Hingula washery shall be 10 years. The washing of coal will lead to improvement in performance of power plant, reduction in particulate emission, reduction in load on Railway Network and reduction in handling and transportation cost of coal and solid waste.

1.3 BRIEF DESCRIPTION OF NATURE, SIZE, LOCATION OF THE PROJECT

1.3.1 Location of Proposed Washery MCL has identified land adjacent to the proposed Railway siding of APGENCO Washery for construction of Hingula washery and the same is under possession of MCL. The proposed site for washery is within the leasehold area of Balram OCP and in between OB Dump & Railway siding of APGENCO. Initially, land of 30 Ha (600m length & 500m wide) at Balram Opencast Project in Hingula Area was identified by MCL for the proposed washery. From the Surface Plan of Balram Opencast Project in Hingula Area, it is quite evident that a seasonal nallah is flowing through the proposed land. Moreover, a part of OB Dump is also falling under the identified area of proposed land. In light of the above, CMPDI team & MCL authorities jointly decided to ascertain exact area of usable land suitable for setting up of the washery with length & breadth excluding the seasonal nallah & part of the OB dump those were falling under the proposed land. Hence, the proposed site for Hingula Washery was finalized within an area of 17Ha, situated in the lease hold area of Balram OC Extension Project, which falls between latitudes 200 56’02’’ N & 20058’ 28’’ N and longitudes 85002’ 52’’ E & 85006’ 57’’ E.

2.1.6 Technology and Process Description The Washery shall be built with the state-of-the-art technology by Monnet Ispat & Energy Ltd. with the following features in Hingula area of MCL. Washing technology, for the proposed Hingula washery, is based on Heavy Media Separation (HM Cyclone) and the washing circuit is a closed circuit with zero water discharge. The raw coal receiving section has been designed for 2000 TPH (dry) and the washing section for 1700 TPH (dry) as required in the bid documents. However, MCL will supply 10 Mtpa of raw coal on as received basis (arb). The solids material balance has been shown on dry basis for 2000 t of raw coal receiving section and 1700 TPH (dry) for washing section and the corresponding material balance has been done. The washery is mainly divided into three sections viz. i) Pre washing section ii) Washing section and iii) Post washing section.

PRE-WASHING SECTION Raw coal of size (-) 100 mm as assured by MCL in respect of quality and quantity shall be received from Hingula-II expansion OCP through Pipe Conveyors and shall be collected in a surge bunker. Alternatively, in case of emergency, raw coal will also be received into receiving pits through tippers/dumpers by road. There will be two streams of crushing and screening system for bringing down raw coal size from (-) 100 mm into (-) 40 mm. Raw Coal of size (-) 100 mm shall be fed to a primary Vibrating Screens of 40 mm opening size from Surge Bunker by Belt Conveyors. The raw coal from receiving pits will also be fed on to the vibrating screen by means of Belt Conveyors. The overflow fraction of Vibrating Screen i.e. 100-40 mm size coal shall be fed into Double Roll Crusher, stage-l, and shall be crushed down to (-) 40 mm size. Crushers output shall further be screened by secondary Vibrating Check Screen of 40 mm size openings. The overflow fraction of Vibrating Screen i.e. (+) 40 mm size coal shall further be crushed by Double Roll Crushers, stage-2, to get the desired product of (-) 40 mm size and will be mixed with the underflow fractions of primary and secondary Vibrating Screens i.e. (-) 40 mm size coal and further the material shall be discharged either into Raw coal Tube Stacker or into Surge Hoppers by means of Belt Conveyor from where it will be sent to washing section.

WASHING SECTION There will be module of four streams each having 2.5 Mtpa capacity in the washing section. The washing process is segregation of (-) 10 mm unwashed fraction from the feed and washing the 40-10 mm coarse fraction in Heavy Medium Cyclones and blending of unwashed fraction with washed coal produced in H M Cyclone circuit. Crushed coal (-40 mm feed coal) will be fed on to Sizing Screens of (-) 10 mm openings by means of Belt Conveyors (Unit No. C15 & C18) where the (-) 10 mm fraction will be separated and collected by unwashed fraction coal collecting conveyors which will discharge the material on to respective washed coal conveyors. The Sizing Screens overflow fraction i.e. 40 - 10 mm size coal shall be discharged on to Desliming Screens having aperture of 0.5 mm where desliming water shall be applied through sprays from overhead tanks. (-) 0.5 mm coal shall be separated with the


II-4

underflow of the screens and it will be collected in slurry sumps. The overflow of the screens i.e. 40-10 mm size fraction shall be discharged into Heavy Medium Cyclone Feed tanks where heavy medium shall be added with the coal from Heavy Medium Tank. The coal and heavy medium pulp mixture shall be pumped to 1150 mm diameter HM Cyclones. The HM Cyclones will separate the coal into two products viz. washed coal through overflow and rejects through underflow. The products will be de-pulped and rinsed on De-pulping and Rinsing Screens arranged to receive the overflow and underflows of the cyclones. The overflow of the thickening cyclones in magnetite recovery & magnetite preparation section as well as clarified water from overhead tanks shall be used as rinsing water. The recovered pulp shall be collected back into the HM Tank. The rinsing water which contains magnetite shall be collected in Dilute Medium Tanks. The magnetite in the dilute medium will be recovered through Primary wet magnetic separators followed by thickening cyclones and Secondary Wet Magnetic Separators. The recovered magnetite i.e. over dense medium shall be collected in over dense make up medium tanks from where it will be sent to Heavy Medium Tanks as per the system demand. The loss of magnetite shall be replenished by adding fresh powder magnetite. The powder magnetite will be poured in a sump where water will be added. The mixture will be pumped into Dilute Medium Tank and it will be concentrated through the above mentioned wet primary magnetic and secondary magnetic separators. The slurry which is collected in the slurry tanks shall be fed into Classifying Cyclones to recover the coarse material which will report in the underflow of Classifying Cyclones. The underflow of the cyclones shall be discharged onto High Frequency Screens where the coarse material (Washed coal) will be recovered through the overflow of the screens and shaII be discharged on to the Belt Conveyor on which washed coal (40-10 mm) from the D & R screens as well as the untreated coal fraction (-10 mm) resulted from the sizing screens are also discharged. The overflow of the Classifying Cyclones shall be fed into Radial Thickeners where the ultrafine coal particles shall be collected through underflow of the thickeners and shall be sent to Belt Filter Press in the washery for final dewatering. The dewatered slurry in the form of cake shall be discharged onto rejects conveyor on which rejects from D & R screens of the H M Cyclone circuit will also be discharged.

In order to expedite necessary clearances EC/FC for construction of Washery, Advisor (E&F) mentioned that Coal Companies have to mention the use of washery rejects in EMP that either (a) the washery rejects does not contain any polluting material and thereby the rejects can be dumped or (b) Rejects would be sold through e-auction or MoU route as it has some calorific value. MCL, after due consideration to the possibility of utilising rejects in the FBC power plant took a decision that utilizing rejects in the FBC power plant shall not be possible because of non-availability of land and water required for FBC power plant. In the 155th meeting of Board of Directors of MCL held on 05.02.2014, the Board approved the sale of rejects from Hingula washery of MCL either through e-auction or MOU route. This was in line with the 75th meeting of CMDs held on 07.05.2013 wherein it was decided that EOI shall be floated to sell the reject from the proposed washeries. Regarding temporary storage of reject

For temporary storage of Rejects, a piece of land measuring 10 Ha (400 m x 250 m) adjacent to the northern side of the proposed washery has been identified. The reject site of 10 ha is sufficient to accommodate the available reject (@193 TPH) for 6 months. However, rejects shall not be stored at temporary storage site beyond 3 months. BOMO will transport rejects by covered belt conveyor to the temporary storage site, distance of which is about 760 m from the washery site. Height of discharge point of the conveyor shall preferably be kept above 15 m level for effective storage of rejects. The reject will be regularly disposed off to the prospective buyers on appropriate mode with due consideration to all statutory environmental stipulations.

CHAPTER 3

ANALYSIS OF ALTERNATIVES (Technology and Sites)

3.1 INTRODUCTION

The scoping exercise results in need for consideration of alternative technologies on account of predicted environmental impact. Alternatives have been considered for ● Selection of site for the project ● Selection of appropriate Technology for Coal Washing

3.2 SELECTION OF SITE FOR WASHERY

Basic considerations in deciding the location of plant site are listed below in order of its significance.

Nearness to sources of main raw materials.

Availability of sufficient stretch of land with relatively flat terrain.

Availability of necessary infrastructure such as transportation, communication, roads, water, etc.

Convenient rail and road links.

Availability of skilled and unskilled manpower.

The site considered for the proposed washery is in the close proximity to the source of raw coal. The infrastructure and auxiliary facilities are adequately present for the proposed activity. Initially, land of 30 Ha (600m length & 500m wide) at Balram Opencast Project in Hingula Area was identified by MCL for the proposed washery. From the Surface Plan of Balram Opencast Project in Hingula Area, it is quite evident that a seasonal nallah is flowing through the proposed land. Moreover, a part of OB Dump is also falling under the identified area of proposed land. In light of the above, CMPDI team & MCL authorities jointly decided to ascertain exact area of usable land suitable for setting up of the washery with length & breadth excluding the seasonal nallah & part of the OB dump those were falling under the proposed land. Hence, the proposed site for Hingula Washery was finalized within an area of 17Ha, situated in the lease hold area of Balram OC Extension Project, which falls between latitudes 200 56’ 02’’ N & 200 58’28’’ N and longitudes 850 02’ 52’’ E & 850 06’ 57’’ E. An additional land of 10 Ha has been finalized for temporary storage of reject located at a distance of about 760m from the proposed washery site. The proposed site for Hingula Washery was finalized within an area of 17Ha, situated in the lease hold area of Balram OC Extension Project, which falls between latitudes 200 56’ 02’’ N & 200 58’ 28’’ N and longitudes 850 02’ 52’’ E &

850 06’ 57’’ E. The entire land for washery is non-forest, non-agricultural and is non-coal bearing.

The site which has been selected has following features :- (i) This site is barren land and is free from forest, agriculture and human

habitation and a non-coal bearing area. (ii) Land belongs to the proponent. Hence, construction of Project would

not cause any Resettlement – Rehabilitation issue. (iii) The site is located close to the road network in the area. Moreover, a

railway siding is close to the site. (iv) The source of water for the washery shall be Gandhi Sagar/ Mitti

quarry/any other mine sump of Balram OCP (approx. <3 km). 3.3 SELECTION OF APPROPRIATE TECHNOLOGY

A washery is a facility that washes coal of soil and rock, preparing it for transport to market. The steps involved are as follows:

1) Procuring Run-of-mine (ROM) coal to the washery through various means of transport such as trucks, railways or conveyors.

2) Coal handling within the washery site through various alternatives such as (a)

Stockpiles, (b) Stacking and (c) Reclaiming

3) Crushing

4) Screening

5) Gravity separation of the coal from the contaminants. Gravity separation methods make use of the different relative densities of different grades of coal, and the reject material. The various methods used are as follows, which are further detailed in subsequent paragraphs:

a. Jigs b. Dense medium process c. Dense medium baths (DMBs) d. Dense medium cyclones

6) Fine coal methods: Fine coal is cleaned using froth flotation methods. Denver

cells and Jameson cells are the two flotation methods used. Spirals perform a simple, low cost and reasonably efficient separation of fine sized material, based on particle density and size.


III-3

7) Dewatering as follows: a. Dewatering product coal: Water is removed from the product to reduce the

mass, and runoff on the stockpile. Different methods of dewatering exist, including coarse coal centrifuges, screen bowl centrifuges, slurry screens, Dewatering cyclones, Horizontal belt filters.

b. Dewatering tailings (reject): Water is removed from tailings to recycle water. Filters, centrifuges and thickeners are used in this part of the process. The black-water which is produced as a by-product is typically placed in a coal slurry impoundment.

c. Thickeners: Thickeners are used for dewatering slurries of either tailings or product. A thickener is a large circular tank that is used to settle out the solid material from the water in the feed slurry. The separated water is clarified and reused as process water in the CPP.

Gravity separation methods make use of the different relative densities of different grades of coal, and the reject material. Description of Gravity separation methods

I. Jigs

Jigs are a gravity separation method for coarse coal. Different types of jig include:

Baum jig

Under-air jig

II. Dense medium process

Dense medium gravity separation methods use a material such as magnetite to form a medium denser than water to assist in separation. A cyclone is a conical vessel in which coal along with finely ground magnetite (media) is pumped tangentially to a tapered inlet and short cylindrical section followed by a conical section where the separation takes place. The higher sp. Gr. Fraction being subjected to greater centrifugal forces pull away from the central core and descend downwards towards the apex along the wall of cyclone body and pass out as rejects/middlings. The lighter particles are caught in an upward stream and pass out as clean coal through the cyclone overflow outlet via the vortex finder. Fluid on entry commences in the outer regions of the cyclone body. This combined with rotational motion to which it is constrained creates an outer spiral. The existence of a top central outlet and inability for all the fluid to leave at the cone apex outlet, assist the inward migration of some of the fluid from the external moving mass. The amount of inward migration increases as the apex is neared, i.e. the radius decreased and the fluid which flows in this migratory stream, ultimately reverses its vertical velocity direction and flows upward to the


III-4

cyclone over flow outlet, i.e. vortex finder. Since it is at the same time rotating, the result is an inner spiral. The Heavy media cyclone is lined with very high quality ceramic tiles inside with a specially designed helical profile. A cyclone is the heart of the washing unit in a Heavy media washery. It is a nonmoving part and hence requires very low maintenance. However, the pressure at the inlet of the cyclone is a very important factor and it is suggested to maintain a minimum pressure of around Dx9x9.81xdensity/100 (in bars), where D= the inner diameter of the cyclone in mm. it is important to note that the pressure at which pulp (mixture of coal and magnetite) is introduced in the cyclone is the principal means of controlling the forces within the cyclone. With the decrease in pressure more coal shall report to the discard/middlings, thus impairing the efficiency of separation. If due to some reason the cyclone feed pump is not being able to deliver the required pressure at the inlet of the cyclone, feed should immediately be stopped and the pipelines, tank and pump should be properly checked for any jamming and any jamming should be properly cleaned before starting the circuit or the feed.

III. Dense medium baths (DMBs) Different types of DMB include:

Teska bath

Daniels bath

Leebar bath

Tromp shallow bath

Drewboy bath

Barvoys bath

Chance cone

Wemco drum

IV. Dense medium cyclones

A mixture of raw coal and dense medium enters the cyclone at a predetermined flow rate and pressure. A vortex is formed, and the high density reject forced to the outside to the underflow orifice discharge, also called spigot. The cleaned coal goes longitudinally down the axis of the cyclone and leaves the cyclone through the overflow orifice, also called the vortex finder. From the overflow orifice, the coal goes into the overflow chamber, and is discharged to the next stage of the process. Criteria for selection of appropriate technology are among the available technologies for beneficiation / washing of coal. - ● Characteristics of raw coal ● Required quality of product coal ● Maximum yield of product coal ● Reliability of technology


III-5

Chosen Technology The selected process is widely adapted technology i.e. first removing untreated fraction from the crushed raw coal to desired washable size and then treat the other washed fraction using wet process through HM Cyclone System, the medium used being magnetite pulp. It is known fact that all the HM Cyclones plants are performing well and giving good results. The technology provides a closed circuit operation with zero effluent discharge outside the washery. The technology to be used in proposed Hingula washery has been dealt in detail in chapter-2. The flow sheet of Hingula washery is given in figure 3.1.

3.4 DISPOSAL OF WASHERY REJECTS In order to expedite necessary clearances EC/FC for construction of Washery, Advisor (E&F) mentioned that Coal Companies have to mention the use of washery rejects in EMP that either (a) the washery rejects does not contain any polluting material and thereby the rejects can be dumped or (b) Rejects would be sold through e-auction or MoU route as it has some calorific value. For temporary storage of Rejects, a piece of land measuring 10 Ha (400 m x 250 m) adjacent to the northern side of the proposed washery has been identified. BOM Operator will transport rejects by covered belt conveyor to the temporary storage site, distance of which is about 760 m from the washery site. Height of discharge point of the conveyor shall preferably be kept above 15 m level for effective storage of rejects. Rejects shall not be stored at temporary storage site beyond 3 months. The reject will be regularly disposed off to the prospective buyers on appropriate mode with due consideration to all statutory environmental stipulations.

4.2.1.1 Soil Quality

To assess the baseline soil quality, soil samples were collected from identified locations in core & buffer zones using augers at depths 30, 60 and 100 cms. The samples were analyzed for chemical parameters like pH, EC, N, P, K and engineering parameters like textural class, bulk density, liquid limit, field capacity, wilting coefficient and available water storage capacity.

4.2.1.2 Rationale behind selection of sampling stations

Soil characteristics, erosion aspects, soil fertility etc., have direct bearing on the environment. Knowledge of soil parameters is essential for the planning and implementation of afforestation. Further, major mining activities affect the soil regime of the surrounding areas directly or indirectly. Hence, it becomes important to study the soil characteristics. By keeping the above aspects in view, four locations are selected in the core and buffer zone. Locations are selected in such a way that different types of soils for supporting different species of vegetation are covered. The soil quality monitoring stations are furnished below and are shown in Plate 10C and Table 4.2.

4.2.3 Air Environment

To assess the ambient air quality status, monitoring stations were identified on the basis of meteorology in the upwind and downwind direction as well as to represent the cross sectional scenario of the project site. Based on the production activities, the parameters chosen for assessment of air quality are Particulate Matter <10 (PM10), Particulate Matter <2.5 (PM2.5), Sulphur dioxide (SO2), Oxides of Nitrogen (NOx) Corban Monoxide(CO), Ammonia (NH3), Ozone (O3), Benzene (C6H6), Lead (Pb), Benzo-pyrene (BaP), Arsenic(As), Nickel (Ni) and other heavy metals.

Calibrated Respirable Dust sampler (with an average flow of 1.2 - 1.4 m3/min.) were used for monitoring of PM10 and a tapping provided in the hopper of the same sampler was utilized for sampling of SO2, NOx with proper flow controller (1 L/min).The heavy metal like Arsenic, Lead, Nickel, Mercury, Chromium, Selenium, Cobalt, Copper, Zinc and Magnesium were also collected in EPM 2000 filter paper by using High volume sampler. Calibrated APM 550 Fine Particle Sampler (with an average flow of 16.7 LPM) was used for monitoring of PM2.5. A temporary field laboratory for the purpose of calibration of equipments and standardisation of analytical procedures was also established.

4.2.3.1 PM & PM10

Calibrated Respirable Dust Sampler with Whatman’s GF/A micro fibre filter paper was used for the determination of PM & PM10 is a measure of particulate

matter having size <10 microns. The dust particles having size >10 microns is being collected in the cyclone and measured. This along with PM10 value gives

total PM.

4.2.3.2 PM2.5

Calibrated APM 550 Fine Particle Sampler with Whatman’s standard PTFE 47 mm diameter filter media was used for the determination of Fine Particles (PM2.5). PM2.5 is a measure of particulate matter having size <2.5 microns. APM

550 Fine Particle Sampler is based on impactor designs standardized by USEPA for ambient air quality monitoring.

4.2.3.3 SO2 (Modified West & Geake Spectrophotometer method)

Ambient air is bubbled at the rate of 1.0 l/min in an impinger containing a scrubbing solution of Sodium-Tetra ChloroMercurate. The resultant complex is reacted with P-Rosaniline and Formaldehyde to form coloured Para-Rosaniline methyl sulphuric acid. The absorbance of the solution is measured in a Spectrophotometer at a wavelength of 560nm. The SO2 is then calculated from

standard graph.

4.2.3.4 NO2 (Jacob &Hocheiser modified method)

Ambient air is bubbled at the rate of 1.0 l/min in an impinger containing a solution of Sodium Hydroxide and Sodium Arsenate. The resultant Nitrite Ion is reacted with Phosphoric acid, Sulphanilamide and N-ethylene di-amine di-hydro chloride to form a coloured complex. The absorbance is measured in a Spectrophotometer at a wavelength of 540 nm. The concentration of NO2 is then calculated by using standard graph.

4.2.3.5 Ozone

Ambient air is bubbled at the rate of 1.0 l/min in an impinger containing absorbing solution of 1% of KI in 0.1m Phosphate buffer. The released iodine equivalent of the concentration of oxidant present in the air is determined spectrophotometrically by measuring the absorption of triiodine ion at 352 nm. The concentration of O3 is then calculated by using standard graph.

4.2.3.6 Ammonia

Ambient air is bubbled at the rate of 1.0 l/min in an impinger containing absorbing solution of 0.1N H2SO4. The resultant ammonium sulfate reacted phenol and alkaline NaOH to produce indo phenol, a blue dye. The absorbance is measured in a Spectrophotometer at a wavelength of 630 nm. The concentration of NH3 is then calculated by using standard graph.

4.2.3.7 Benzene and Benzo-pyrene

Calibrated Respirable Dust Sampler with EPM2000 micro fibre filter paper was used for the determination. After extraction and sample processing the individual PAH compounds will be determined using capillary gas chromatograph equipped with flame ionization detector.

4.2.3.8 CO

The CO content in ambient air was collected in pulse pumps and determined by non-dispersive infrared (NDIR) spectroscopy.

4.2.3.9 Heavy metals

The heavy metal like Arsenic, Lead, Nickel, Mercury, Chromium, Selenium, Cobalt, Copper, Zinc and Magnesium were also collected in EPM 2000 filter paper by using High volume sampler. The AAS technique makes use of absorption spectrophotometry to assess the concentration of metals in the sample. The method is based on active sampling using PM10 high volume sampler and then sample analysis is done by Atomic absorption spectrophotometer.

4.2.3.10 Location of monitoring stations and observations

The principle objective of the ambient air quality monitoring is to assess the existing levels of air pollutants as well as the regional background concentration in and around the project area. Air pollution forms an important and critical factor to study the environmental issues in the mining areas. Air quality has to be


IV-9

frequently monitored to know the extent of pollution due to mining and allied activities. The ambient air quality monitoring was carried out at ten stations.

The monitoring stations were identified on the basis of meteorology in the upwind and downwind direction as well as to represent the cross sectional scenario of the project site. The monitoring network was designed based on the available meteorological and climatologically norms of predominant wind direction and wind speed of the study region.

The parameters selected for analyzing the air quality status are Particulate Matter <10 & 2.5, Sulphur dioxide (SO2), Nitrogen oxides (NOx) and Heavy Metals. As per the existing norms, air quality monitoring was carried out for the all the parameters under NAAQ standards 2009 for two days in a week for twelve weeks in the season. The location details of ambient air quality monitoring stations are given in the Table - 4.5 and are shown in Plate No 10B.

4.2.3.13 Summary

The ambient air quality monitoring was carried out at 10 location including one location in Core zone. A total of 24 samples for each parameter at each location at regular interval were collected. In general, all the parameters monitored were found to be well within the prescribed limits of CPCB at Core zone. The PM10 values monitored at 6 locations out of 9 locations in buffer zone were found to

be exceeding the limits. The maximum observed value was 115 g/m3 at Jaganath Colony. The PM10 values were also found to be exceeding in the other monitoring locations like Danara village, Malibandha Village, Kumanda Village, Natidi village and Rakas village. These may be due to the fugitive emission from the transportation and other allied mining activates in the buffer area. There are about 5 open cast mines in operation in the study area by MCL. However all other parameters except PM10 were found to be well within the limit.

4.2.4 Water Environment

Water samples were collected and analyzed as per procedures outlined in IS-2488/ IS-3025 / AWWA / APHA. Sterilized bottles were used for collection of water sample for bacteriological analysis, stored in icebox and transported to the laboratory for the analysis. Parameters like pH, Temperature, Dissolved Oxygen, Residual Chlorine, Conductivity, Free Ammonia, Total Hardness, Calcium Hardness and Magnesium Hardness were analyzed in the field while collecting the samples. MPN index of Coli forms are determined in the laboratory as per standard methods. The analyses were carried out as per the BIS & APHA standard methods.


Any adverse impact or pollution consequence of water will have serious effect on the environment. Hence, it becomes important to assess the water quality periodically in the mining area. Thus, to assess the water quality, nine locations are identified and samples (9 Nos.) were collected and analyzed for physico-chemical and heavy metal parameters. Bacterial examination was also carried out to find out the Coliform contamination (if any) at water sources. The water quality assessment has been made from the following monitoring stations and is shown in Table 4.8 and plate No. 10C

4.2.6.4 Conclusion

Under this project, villages have been surveyed in order to focus the living standard, occupational position and the possession of assets of the villagers. Villagers taken under this project still cultivate their land in a traditional pattern and they are dependent mostly upon seasonal rain. The prominent occupations of the villagers are cultivation (agriculture) and non-agriculture workers. Some of the villagers are employed under M.C.L also. Villages have been developed to the extent that Govt. health and primary education facilities are well available there. A vital improvement has also been seen in the living standard of the villagers. Televisions have joined radios in almost every household as a medium of entertainment and communication. Villagers are also enjoying other electrical accessories due

to availability of power supply. People use two wheelers for purpose of travelling. In addition to some kachcha houses, most of other houses are made of concrete. M.C.L runs various projects in order to provide basic facilities like health, water, road and community hall etc. to the villagers. These M.C.L projects have directly or indirectly created various opportunities of employment in the region. A large number of villagers are engaged in such projects. These additional employments have big role in improving the living standards of villagers.

4.2.7 BIOLOGICAL ENVIRONMENT

The basic objectives of the study are to evaluate the status of the flora and fauna of the core zone and the buffer zone with specific reference to the rare or endangered or endemic or threatened (REET) species. Core zone is defined as the area required for the plant and temporary storage for reject while the surrounding areas up to a distance of 10 km from the boundary of the core zone is described as the buffer zone. The study is also designed to evaluate the adverse impacts of the proposed washery and to suggest remedial/mitigation measures in accordance with the objectives as desired by the Ministry of Environment and Forests (MoEF), Government of India.

4.2.7.1 Methodology of Sampling:

Flora and fauna studies were carried out during the month of June-2014, to assess the list of terrestrial plant and animal species that occur in the core zone and the buffer zone up to 10km distance from the core zone. The entire core zone and its buffer zone have been surveyed for enumeration of flora and fauna. Within the core zone, 6 locations of 100m2 each were chosen or phyto-sociological investigation using restricted random sampling techniques. Within the 10km buffer zone, 10 samples of 100m2 each were chosen at random. Analysis of vegetation was done using samples of 100 m x 10 m belt transects for tree species, 10 m x 10 m quadrats for shrubs and 1 m x 1 m quadrats for herbs. Equipment / Instruments deployed: Quadrats

Measuring tapes,

GPS

Camera

Binocular

Plankton net

Storage PP bottles and

Insect sweep nest etc.

4.2.7.2 Rationale behind sampling

As the core and buffer zones were subject to anthropogenic disturbances and other biotic pressures, the original natural vegetation has been modified. The distributions of different species do not follow a normal or


IV-35

random pattern. On the other hand, the pattern of distribution was modified by such practices as denudation, introduction, afforestation etc. In view of the above, restricted random techniques were used. In this process, the number of samples in different formations and communities are proportionate to the total area under that community. In case of vertebrate species, no sampling could be done. Depending on as and when sighted, the species are recorded if found within the delimited project and buffer zones, the animal (fauna) species are listed on secondary data and circumstances evidence besides direct observations. These techniques are accepted in EIA studies as per the EIA Notification of 2006.

4.2.7.3 Status of flora and fauna in the Core zone

4.2.7.3.1 Flora in the core zone

Maximum area of the core zone is barren land and scrubland. During floristic survey in the core zone of Hingula Washery, a total of 34 plant species were recorded out of which 18 herbs, 5 shrubs and 11 species of Trees. There were no rare or endangered or endemic or threatened (REET) plant species in Core zone. List of plant species found in core zone is given in Annexure – 7B

4.2.7.3.2 Fauna in the core zone

The Invertebrates fauna recorded in this core zone were 4 species of Phylum Annelida and 10 species of phylum Arthropoda. Observed Vertebrates were 5 species of Amphibians and 5 species of Reptiles belongs to the schedule IV as per Wildlife Protection Act. Avian fauna recorded in this zone were mostly migratory birds since there were no permanent habitats of them encountered during survey. Seventeen species of avi-fauna were observed belong to schedule IV. There were four species of mammals observed three species belongs to schedule IV, one species status not enlisted. There is no specific migratory route in the core zone.

4.2.7.4 Status of flora in the Buffer zone

The buffer zone is relatively rich in habitat and biodiversity due to forest area, plantation, scrublands, residential, agricultural, sacred groves and avenue/road side plants which enhance diversity of buffer zone. There were 133 species of plants recorded in the buffer zone the entire list given in the different tables among them Trees were 55, Shrubs and Herbs 39.

4.2.7.4.1 Agricultural crops

Crop fields located close to the Danara, Natara, Natadi, TilePasi and Nisha villages were surveyed for enlisting agricultural crops in study area, the buffer zone. Besides the agriculture biodiversity that is of great economic significance is the domesticated diversity of the plant species made by farmers the long farming tradition, soil, topography and rainfall variation have permitted the development of diverse agriculture ecosystems in turn enhance the biodiversity in the buffer zone. Which include 23 species of


IV-36

agriculture crops (Table) viz. Arachis hypogea, Dolichos biflorus, Oriza sativa, Sesamum indicum, Triticum aestivum, Vigna mungo, Vigna Musa acuminate radiate, Zea mays, Achras sapota, Citrus medica. Citrus aurantifolia, Mangifera indica, Psidium guyava, Abelmoschus esculentus, Allium cepa, Capsicum annuum, Caricca papaya, Dolichos lablab, Lycopersicon esculentum, Moringa oleifera, Solanum melongena and Solanum tuberosum. Fruit trees of Mango, Guava, Sapota, custard apple, Casuarinfa and Eucalyptus, Teak and Subabul are the common avenue trees scattered/densely populated in different roadside plantations, scrubland, green belt development and forest areas.

4.2.7.4.2 Commercial crops

In some of the area local people use to grow vegetables to sale in the local market. A part of the vegetables grown by them is also meant for their day –to -day requirements.

4.2.7.4.3 Plantation

Road side plantations are done mostly for shadowing the road net works important species wereArtocarpus intigrifofta, Casia tora, Tamarindus indica, Caesalpinia pulcherima, Moringa oleifera, Psidium guava, Phoenix dactylifera, Ficus bengalensis, Mangifera indica, Micheiia champaka, Dendrocafamus strictus, Borassus flabellifer, Saraca indica, Ficus hispsda, Madhuca indica, Melia azadirachta and Zizyphus jujube, Besides road side plantation, often mixed mango grooves were also noticed close to some of the villages in the study area. One such mango groove path studied was close to Danara. Tree species recorded were Shorea robasta, Madhucha indica and Mangifera indica. In the floor of the grooves the saplings of Holarhena antedysenterica, Dyosterus melanoylon and occasionally Butea monosperma were noticed.

4.2.7.4.4 Natural vegetation / forest type

For the survey of natural vegetation and forest type in the study area the following sites were inspected. 1). Rakas R.F., 2). Kandhaberani and 3). Kandhal R.F., forests are situated in the study area. These three forest areas are located on the plane lands. The dominant plant species observed in this section are Acacia auriculiformis, Bauhinia racemosa, Mangifera indica, Morinda tinctoria, Terminalia arjuna, Terminalia tomentosa, Acacia arabica, Adhatoda vasica, Bauhinia purpurea, Ficus benghalensis, Mimuso pselengii, Pterocarpus marsupium, Terminalia bellerica, Ziyphus jujube, Alstonia scholaris, Buchanania lanzan, Cassia siamea, Michelia champaca, Anogeissus latifolia, Dalbergia paniculata, Ficus glomerata, Polyathia longifolia, Acacia leucophloea, Albizzia chinensis, Gmelina arborea, Sterculi aurens, Zizyphus xyloria, Terminalia chebula, Artocarpus heterophyllus, Syzyzium cumini, Acacia catechu, Adina cordifolia, Anthocephalus cadamba, Bauhinia veriegata, Cereya arborea, Diospyros melanoxylon, Gardenia latifolia, Phoenix sylvestris, Pongamia pinnata, Wrightia tinctoria, Ailanthus exelsa, Mitragyna parviflora, Moringa oleifera, Emblica robusta, Artocarpus heterophyllus, Butea monosperma, Dalbergialatifolia, Ficus religiosa,

The vegetation in the North West section is much thick as compared to the North East section and dominated by thick forest areas. Sampling location selected for the study area is Kumunda. The plant species observed in the forest and non forest area are more or less similar to the North East area. Detailed vegetation analysis of these forest sites revealed that forests are categonzeO as tropical dry deciduous type. All these forests are mostly opsiy canopied due to biotic interference and have Shorea robusta as the dominant species. Other co-dominant species areBuchanania lanzan and Terminalia tomentosa. Thus vegetation of the site can be categorized as Shorea-Buchanania -Terminalia type.

4.2.7.4.5 Aquatic flora

Following aquatic plant species were recorded while inspecting some of the ponds in the core zone.

SI No. Species Local name

1. Ipomoea crassicaulis Amari

5. Nympheanouchalli Lai kain

6 Phytoplanktons

4.2.7.4.6 Endangered/ Endemic species.

During the period of survey in the buffer zone, no endangered or endemic species could be noticed.The vegetation of the buffer zone comprises of

scrubland, forest patch, agriculture field and village as well as roadside trees. In the scrubland Holorrhena antidysenterica is the dominant species. Scrublands are the product of heavy biotic interference. The nature of forest is open canopy, dry deciduous type with Sal as the dominant species. Mahul is the other co-dominant species in the area. There is also agricultural activity particularly rice cultivation. The buffer zone does not contain any endangered or rare plant species.

4.2.7.5 Status of fauna in the Buffer zone

4.2.7.5.1 Amphibians and Reptiles

During field survey species like House lizard (Hemidactylus brooki), Rock gaeko (Hemidactylus maculates), Garden gaeko (Colotes versicolor), Skink (Mabuyabibroni) were observed in different locations of buffer zone. During public consultation it was noted that, some common species of reptiles and amphibians found in these region are Indian Python (Python molurus), Common Indian krait (Dendrelaphisa haetulla), Indian cobra (Naja naja), Russell’s viper (Ophiophogus hannah), Common Indian toad (Bufo melanosticus), Balloon frog (Uperodon globulosus), Paddy field frog


IV-38

(Ranalimnocharis). The list of Reptiles and Amphibians recorded in core and buffer zone of the study area of proposed project site is presented in respective Tables.

4.2.7.5.2 Avifauna

The birds diversity has been estimated in four most important habitat types, i.e. human habitation, agriculture fields, forest area and water bodies. The observations were made based on direct sightings and birdcalls. The core zone of the study area covers village areas and agriculture fields and consists of bushy vegetation which attracts passerine birds. In the north East boundary,Brahmani River is flowing through the study area. This river attracts many bird species including species like Indian pond heron (Ardeola grayii), Cattle egret (Bubucus ibis), Red wattled lapwing (Vanellus indicus), Indian small blue kingfisher (Alcedo attahis), Indian white breasted kingfisher (Halcyon smyrnensis), Indian little ringed plover (Charadriusdubius) etc.

During the survey within villages, several species of birds were observed in the agriculture fields. The most common species observed were Indian spotted dove (Stretopelia chinensis), South Indian black drongo (Dicrurus adsimilis), Indian myna (Acrido therestristis), Indian small green bee eater (Merops orientalis), Indian house crow (Corvus splendens), Indian little brown dove (Stretopelia senegalensis), Large Indian parakeet (Psitta culaeupatria), Rose- ringed parakeet (Psittacu lakrameri), Indian golden oriole (Oriolu soriolus), and Indian house sparrow (Passer domesticus) etc. List of birds observed in core and buffer zone in the study area are presented in respective tables.

4.2.7.5.3 Mammals

During the survey no elephant was seen by the team. But during public consultation the villagers mentioned the presence of elephant herds which were often seen in agriculture fields during winter every year. Elephants visit the following region of the study area in search of food. This area has prominent patches of vegetation and forest area. Thus, the entry of elephants within the area is through specific path. The villages which are mostly affected by the elephant movement are Natri, Banbaspur, Ambapala, Kumunda, Malibandha and Balichandrapur. The probable reason for their movement into human habitation is availability of easy food sources like paddy field, banana plantation etc. which are major crops in this area. The dense patches of forest in this region form ideal places for food and shelter for them. This movement of elephants gives rise to man animal conflicts which emphasizes on the need of habitat conservation for elephants in this region.

4.2.7.6 Conclusion and General Remark

Elephants and Sloth bear are the only migratory mammals in the area coming from distant places during forest fire. However, it is not a common migratory route for wild animals.


IV-39

In the project area, forest area was noticed as fragmented patches due to human habitation pressure in buffer zone. The nature of the forest is open canopied dry deciduous type. At many places, the forest because of biotic interference has been converted to scrubland. Biotic pressure has also affected the natural wild life fauna of the area. The area, as revealed from the survey, does not support any rare and endangered flora and fauna.

4.2.7.7 BROAD OBSERVATION OF THE FLORA & FAUNA STUDY

The report reveals the presence of following wild animals in buffer zones under different Schedules of the Wild life (Protection) Act 1972. All such animals are found in other parts of the State. The area does not have any endangered species. The records of faunal species collected during the survey were based on

both direct and indirect evidences. As per the informal discussions with the local people, the schedule I and II fauna such as Elephas maximus, Melusrus ursinus, and Golden jackel, Canis aureus Juncle cat, Felis chaus, and Phyton, Python molurus were not very frequently seen in the Buffer zone. Thus, during the period of survey in the buffer zone, no endangered or endemic species could be noticed.

Faunal Impacts were assessed in regard to the following issues. Habitat Loss and Wildlife Migration Patterns. No significant habitat loss is anticipated. Potential wildlife crossing zones were not identified by experts of Ecology, Flora and Fauna. There was no residential birds or

wild mammals evidenced by the absence of nests of birds resting or hiding places of mammals. Observed avi-fauna in the core area were common birds. No threatened or endangered floral species are located within the core and buffer zone of the project area. After the detailed flora and fauna study within the buffer zone, it was observed that is no migratory corridor of fauna in the study area. No ecologically sensitive area (National Park / WL Sanctuary Tiger Reserve, etc) lies within the 15km buffer zone. Details of Flora and Fauna data has been enclosed in Annexure-7A & 7B

4.2.8 Solid Waste facility

4.2.8.1 Washery Reject

Major solid waste generated from washery shall be “Washery Rejects”. Total quantity of rejects that shall be generated from the washery is 1.09 MTPA at the rate of 193.0 TPH. The rejects generated from the HM Cyclone circuit as well as the products of Belt Press Filters shall be collected by reject belt conveyor and shall be transported to proposed temporary storage site, a piece of land measuring 10 Ha (400 m x 250 m), adjacent to the northern side of the proposed washery, through covered belt conveyor (01 Nos. and capacity 400 TPH).The reject site of 10 ha, about 760 m from the washery site, is sufficient to temporarily accommodate the available reject (@193 TPH) for 6 months. However, rejects shall not be stored at temporary storage site beyond 3 months. Height

CHAPTER - 5

ANTICIPATED ENVIRONMENTAL IMPACT ASSESSMENT & MITIGATION MEASURES

5.0 GENERAL

The major potential source of environmental contamination from coal washeries includes: washery rejects (solid waste), liquid effluent streams, coal storage and handling (fugitive dust and runoff), and coal transportation (fugitive dust). Coal washery rejects consists of coal and other minerals associated with the coal seam. The main air pollutant from storage, transportation and handling of raw coal and washed coal is fugitive dust. The water pollutants directly associated with the washing of coal are primarily dissolved and suspended solids. The dissolved solids are mostly inorganic in nature.

5.1 LAND ENVIRONMENT

The proposed site has 17 Hectares land for plant and 10 Hectares for temporary storage of rejects. Various installations required for the washery will be suitably located within the area of 17 Ha. The major portion of the land for proposed washery is Barren/scrubland and no nallah/stream passes through the site for proposed washery. Land Use/ Cover Map of Core & Buffer Zones of Hingula Washery Project based on Satellite Data of the Year 2013 is enclosed as Plate no. 8 in the EIA/EMP report. Table 5.1: Existing Land use pattern

V-2

Anticipated Impact

During the construction phase, the adverse impact is due to soil erosion and blanketing of the top soil. Some readily erode due to pumping and digging activities. Temporary hutments, construction activities and poor sanitation facilities will diminish the actual aesthetic value of the area.

Impact due to storage of coal and washery reject. Impact on topography, water drainage and land use. Impact on surface streams. Impact due to project development on the surrounding areas and transportation

of raw materials and finished products Impact on immediate surrounding due to construction of washery.

Mitigation Measures

No land acquisition is involved as land is already in possession of MCL and it is in the lease hold area of Balram OCP in the Hingula Area.

During operation of the plant, the land-use pattern will stabilize and no further

drastic change is expected. Colony, schools, hospitals, recreation centers etc. will be shared by the adjoining coal projects. If needed, fertile soil will be brought from elsewhere over the existing soils for fresh plantation. Land escaping will be undertaken to make the land-form compatible with the surrounding.

Surface run off caused by precipitation may pass through stock-piles and reject dumps causing erosion and degradation in quality of soil. While passing through the stock-piles and reject dumps, it may carry solid suspensions and chemicals. Drainage for surface run-off shall be incorporated at all the required places viz. around the reject storage site, raw coal storage site, along the boundary of the washery.

Since, the major portion of land for proposed washery is barren/scrubland, the Impact on land after construction of washery shall be minimal. No major nallah/stream passes through the site for proposed washery, hence there shall be no major impact on drainage pattern. Topography of the proposed site will change because of the structures which will come up after the commissioning of the plant.

Washery will be designed for zero discharge. During the construction of the Washery the existing Roads/railway sidings will be

used for transport of men and material. New approach roads will be constructed in and around washery site for connecting it to the existing road network of the area for transportation of men and material. During construction of washery, waste generated shall be limited to construction materials, debris etc. which shall either be leveled in the low lying areas within the premises or back filled where ever required in the plant during construction of roads and embankments.

Land for Hingula Washery is in possession of MCL and it is in the lease hold area of Balram OCP. No habitation, major stream, natural vegetation exists within immediate surroundings.

Green belt (15m wide) of area 1.45 Ha will be developed in and around the washery site

5.2 Water Environment

Anticipated impact

Quantity and characteristics of industrial effluent and their impact on the environment

Impact on ground and surface water due to run-off from stockpiles and washery rejects

Impact on surface water bodies due to the discharge of effluent during the heavy rainfall and during periodic cleaning of the system, if any

Impact on ground water and surface water availability due to the project usage Mitigation Measures

The process of the proposed washery is based on closed water circuit system. All the water fed into the system will be collected after use and re-circulated, after treatment, in various units and no effluent will be allowed to escape into the natural drainage system. Moreover, washery circuit envisages dewatering system like belt press filter & High Frequency Screens for efficient recovery of solids from the slurry. The filtrate water from these equipment will be recycled back to the system to ensure closed water system. The underflow of Radial thickener, in case of emergency, may be fed to slime ponds for settling & natural drying and subsequent reclamation of the dried fines. The overflow water of slime ponds will be pumped back for re-use in the process. Thus, the operation of the washery will not cause any pollution to the local source of water.

Provision of surface run-off settling pond shall also be provided. Drainage for surface run-off shall be incorporated at all the required places within the washery and along the washery boundary. These garland drain(s) shall collect and carry the run off to settling pond. Overflow water of the settling pond shall be utilized for plant operation etc. Hence, there will be no impact on groundwater and surface streams.

Washery will be designed for zero discharge. However, in case of emergency underflow from thickener shall be treated in 03 Nos of slime ponds of size 100m x 6m x 2.5 m (each) and treated effluent shall be reused.

Total water demand is 1273 m3/hr out of which 955 m3/hr is recycled water. Make-up water of 150 m3/hr shall be met from Gandhisagar/ Mitti quarry/any other mine sump (of BOCP). Hence, groundwater or surface water shall not be utilized for any industrial use in the washery. Flow diagram showing the details of reuse/recycle to demonstrate the zero discharge operation is given in Figure 2.1 chapter 2.

5.3 Air Environment

Anticipated Impact

The source of air pollution from the coal washery includes from ROM coal transportation, loading and unloading from trucks, handling, grinding, sizing, screening, grinding and intermediate process operations, drying and storage etc.

The impacts on ambient air quality are highlighted in the following paragraphs:


V-4

(a) The ambient air quality is influenced due to the presence of SPM, PM10, PM2.5, SO2 & NOx, which are generated due to various activities like run-of-mine, transportation, loading and unloading from trucks, wagons, handling, grinding, sizing, screening, grinding and intermediate process operations, drying and storage etc. Further, the ambient air quality may be affected marginally to a varying degree due to the mining activities of other nearby mines of MCL. The concentration of pollutants may vary depending upon the various micro-meteorological parameters and the seasons of a year.

(b) As the project area (core zone) of the coal washery is small, the effect on the

climate, rainfall, and temperature shall be negligible.

(c) During the operational phase, activities necessary for washing of coal, its handling and transport are taken up. Such activities having impact on ambient air quality are detailed below:

Water spray arrangements shall be provided at all strategic coal transfer points, enclosures for conveyors etc.

The ambient air quality of the proposed w.r.t. SPM, PM10, PM2.5, SO2& NOx for

the period from 15th March ’14 to 15th June ’14 were within the limits of the prescribed standard except for PM10 values monitored at 6 locations out of 9 locations in buffer zone were found to be exceeding the limits. Suitable mitigation measures as described above shall be taken to make the washery operation eco-friendly, which will result in negligible adverse effect on human being, flora and fauna, soil quality, surface structures and aesthetic value of the surrounding environment.

5.4 Noise Environment

Anticipated Impact

During the construction phase of the washery, the source of noise pollution is expected from machineries used for construction, installation and commissioning of the equipments. During operational phase, noise pollution is expected from following sources of:

(i) Due to operation of the machineries involved in the main process of the plant and DG sets

(ii) Due to noise generated during transportation of materials.

Mitigation Measures The following measures therefore, have been envisaged to reduce the noise level to the minimum and to protect the workers from noise hazard.

Use of equipment with arrangements for absorbing the operational noise. Use of insulated cabins for operators Use of rubber/ polymer liners in chutes and hoppers Use of ear muffs by workers in the zone of high noise source (if any) 15 meter wide green belt around the Washery and service building area (1.45

Ha). Routine preventive maintenance of equipment/HEMM to minimize noise

generation at source. Regular maintenance with prompt replacement of worn-out parts/ liners etc. Operational / work zone – not to exceed 85 db (A) Leq for 8 hours exposure Use of silencer for equipment such as diesel sets and air displacement

equipment Regular monitoring of noise levels at various points.

5.5 Biological Environment

aesthetics.

5.6 Socio-economic Environment

Amenities

The existing amenities in respect of educational, medical, drinking water supply, communication, electric supply and post & telegraph facilities which are presently being utilized by the existing population of the buffer zone is not expected to be strained further due to the reason that further immigration in this area, as on date is not expected. However, any development in the existing facilities can never be ruled out keeping in view the CSR programme of MCL and other rural development progarmmes of State Govt. / Central Govt. Socio Economic Measures No re-settlement and rehabilitation(R&R) is involved in this project. Secondary Employment Opportunities

Coal mining and allied activities dominates the economy of the study area. The Coal Mining and the activities associated with coal mining are the main source of direct and indirect employment and income for the working population of the area. The proposed coal washery project will enhance the direct and indirect employment and add to the total income of the working population of the area.


V-9

Socio-Economic Impact

Within the delineated area of core and buffer zones for this project, it is not expected that any major change in the social structure of the area would take place due to this project, since there is an ongoing project of Balram OCP and the society of buffer zone is in fully stabilised state in the existing mining and industrial environment of the area. Mitigation Measures

During construction of washery, the civil and structural work shall be outsourced by BOM operator to sub-contractors and therefore the manpower will be provided by them (sub-contractor), depending on the work requirement at site. Hence semi-skilled and unskilled labor during construction phase and unskilled labor during operational phases of the project are proposed to be employed from amongst the local population.

Employment opportunity and access to other amenities such as education, health care facilities for local people

11. *Cadmium (ppm) 0.52 0.36 1.37


7.2 Regarding FBC Power Plant

MCL, after due consideration to the possibility of utilizing rejects in the FBC power plant took a decision on utilizing rejects in the FBC power plant. In the 155th meeting of Board of Directors of MCL held on 05.022014, the Board approved the sale of rejects from Hingula washery of MCL either through e-auction or MOU route. This was in line with the 75th meeting of CMDs held on 07.05.2013 wherein it was decided that EOI shall be floated to sell the reject from the proposed washeries.

7.2.1 Regarding temporary storage of reject

For temporary storage of Rejects, a piece of land measuring 10 Ha (400 m x 250 m) adjacent to the northern side of the proposed washery has been identified. The reject site of 10 ha is sufficient to accommodate the available reject (@193 TPH) for 6 months. However, rejects shall not be stored at temporary storage site beyond 3 months. BOMO will transport rejects by covered belt conveyor to the temporary storage site, distance of which is about 760 m from the washery site. Height of discharge point of the conveyor shall preferably be kept above 15 m level for effective storage of rejects.


VII-2

The reject will be regularly disposed off to the prospective buyers on appropriate mode with due consideration to all statutory environmental stipulations.

7.3 Public Consultation

With a view to ascertaining the concern of local affected persons and others who have a plausible stake in environmental impacts of the project / activity a public consultation was conducted at Jagannath colony, post-South Balanda, Talcher, District-Angul. Following course of actions mentioned hereunder is generally followed to have a public consultation:

(1) A proceeding called Public Hearing is conducted in which public

would be directly involved or participate and indirect responses would be received through different modes of communications.

(2) District Magistrate will preside over the Public Hearing process to get public concerns incorporated in the EIA report.

(3) Video-graphs of proceedings would be done and would be enclosed with the application to Expert Committee.

(4) The proceedings will be signed by DM/ADM along with other panel members of the Public Hearing in the same day of hearing.

(5) The proceedings will be displayed in web site and other Govt. offices.

7.4 Risk Assessment 7.4.1 Introduction

Keeping in view the three basic principles i.e. prevention, preparedness (both pro-active and reactive) and mitigation of the effect through rescue, recovery, relief and rehabilitation; a comprehensive blue print of the Risk Management Plan (RMP) has been prepared incorporating the following:

1. Identification and assessment of risks 2. Recommendation of measures to prevent damage to life and

property against such risks. During construction and operation phase of the project, a hazardous situation may arise which ultimately may lead to a risky situation, even a disaster. This disaster may cause loss of life and property. In order to foresee such a situation and anticipate loss of life and property so that they can be minimized or avoided, a risk assessment has been carried out. A brief of the assessment is given below.

7.4.2 Hazard Types

Hazards may be classified broadly into two categories. - Natural Hazards - Manmade Hazards

Natural Hazards

Major causes for natural hazards may be - Earthquake - Flood


VII-3

A. Earthquake: The project is located in zone III as per relevant BIS code.

This zone is located in low risk area for occurrence of earthquake. The washery building and other structures will however be designed with due consideration to the earthquake loading appropriate to this zone as prescribed in BIS code. In addition to incorporating the safety factors at design stage, appropriate earthquake resistant construction techniques will be used.

B. Flood: Likely causes for flooding may be - Flooding by excessive rainfall in the area. - Flooding of site due to flood in Jamunia river. However the washer

will be located on an area 3m above the highest known flood level of the area.

From the above discussion we may conclude that project site is least

hazardous for natural causes. Manmade Causes Manmade causes for hazardous situation may be ● Fire ● Explosion ● Industrial Accidents (A) Fire: There may be several causes for fire, i.e. electrical short circuit,

negligence on part of operators, etc. Appropriate steps will be taken to prevent occurrence of fire in the plant and to control it effectively if at all it occurs. Some of the safeguards and precautions that will be taken are

● Electrical installations will be designed in accordance with

prescribed safety rules to ensure that electrical fire possibility is minimized.

● At the operational stage, all safety rules will be followed. ● Strict quality control for procurement & installation of electrical

installations. ● Display of warning signs in operational area against fire. ● Proper storage of inflammable material like diesel, etc. ● Provision of adequate fire fighting arrangements with a ground

water tank dedicated to fire fighting exclusively. ● Organizing fire fighting drills on regular basis. ● Installation of Portable fire fighters at strategic locations all over the

plant. ● Installation of smoke detectors with Fire Alarm. (B) Explosion: There is no proposal to store any explosive within the

premises. Also no explosive is required for plant operation. (C) Industrial Accidents: Coal washery is regulated under safety rules of

Factories Act. The provisions of the Act relating to the safety would be enforced strictly.


VII-4

(D) Road Accident: Sufficient arrangements for illumination of road including haul roads will be undertaken. Properly planned and designed road crossing will be implemented to prevent vehicular accidents. These are likely to prevent road accidents.

(E) Medical Preparedness: For guarding against accidental hazards the following measures tabulated in Table-7.2 will be taken:

Table-7.2

Sl. No.

Preventive Measures against accidental hazards

1 Emergency Ambulance Service will be kept ready on a 24 hour basis.

2 Doctor and paramedical staff will be made ready during emergency.

3 First Aid Medical facilities will be provided at work place.

The existing and nearby mine has already been provided with a dispensary with qualified doctors in addition to a first aid centre. These will meet the medical emergencies arising out of the accidents.

(F) Other Miscellaneous Measures:

* Proper illumination in the workplaces besides roads will be undertaken.

* Efficient communication system to allow communication link

amongst various work centres to help in avoiding accidents and handling of emergencies.

* Fire alarm and fire fighting system will be provided at project site.

The adoption of preventive measures as enumerated above will ensure

that the operation of this project will be safe as well as environment friendly.

7.5 Organisation

A dedicated organization with sufficient infrastructure would be provided to take care of disasters.

A. Safety Organization: This organization will be responsible for safety

of the plant operations. Head of the safety organization would be reporting to the GM/In-charge of the plant.

B. Disaster Management Organization: There may be occasion when in

spite of all precautions, disasters may occur within the premises. In order to manage such a situation, a separate organization will be created.

(i) Central Control Room: A central control room will be created to

manage the disaster. This will have following facilities.


VII-5

● a public address system to disseminate information to plant operators within the premises.

● the control room will have telephone no. of - Police - Local Administration - Hospital - Fire Station (ii) Floor Level Disaster Management Unit: Floor level units will be

constituted to deal with disaster. (iii) Training programme: Regular training programmes for plant

operators would be organized to make them aware of safety aspects of plant operations & steps to be taken in case of disasters.

(iv) First Aid Centre: For rendering medical aid in case of

occurrence of disaster. (v) Ambulance: An ambulance will be provided for movement of

people needing medical attendance. 7.6 SOCIAL IMPACT ASSESSMENT

The land that has been identified for locating the project is owned by the project proponent & is under its possession. The area is free from any habitation, hence no resettlement & rehabilitation is involved. Also there is no requirement of additional land for development of project infrastructure. Thus, the construction and operation of the project is not likely to cause any adverse impact on social profile of the area. In fact, opening of the project would have positive impact on socio-economic profile that includes. ● Creation of employment opportunity on casual and long-term basis. ● Improvement in physical infrastructure. ● CSR activities will improve social infrastructure in the area. Corporate Social Responsibility carried out for the project/area has been described in section 8.6 of chapter 8.

Medical Facilities There are a number of maternity & child welfare centres and community health centers managed by the State Govt. taking care of the population in the study area. MCL provides the facility of dispensaries at project level and hospitals at Area level and a central hospital exists at company headquarter.

Immunization facilities are also available at every colliery hospital and dispensary. The family planning Camps are held regularly at the hospitals/dispensaries.


VII-6

Every worker is periodically checked up once in every five years and proper record of their health profile including X-ray and laboratory tests are kept.

The importance of such periodical medical examination is to detect and prevent occupational diseases like Pneumoconiosis and Tuberculosis etc.

Preventive measures

The MCL authorities have adopted the following measures to prevent occupational diseases and health hazards.

i) Pre-employment, pre-placement and periodic medical examination

of the employees.

ii) Regular monitoring of working environment and implementation of safety and control measures, to prevent hazards.

iii) Use of protective equipment’s, clothing, helmets, Gas mask, shoes,

etc. iv) Periodical medical examination of every worker is done once in five

years to detect preventable and curable diseases at an early stage.

v) Cases suspected having Pneumoconiosis are examined by a Special Board constituted by the Chief Medical Officer. Established cases are suitably compensated and their job is changed if required.

7.7 Employee Education

Employees will be informed of the need to take precautions and use all protective measures to control fugitive emissions in working environment. They will also be advised of consequences of ignoring these precautions. Employee will be trained in coal handling, and in spill management. Written policies, procedures and measures will be disseminated throughout the different departments of the plant and workers will be trained with regard to their implementation. The employee will be educated about the safety features incorporated by written literature with pictorial and color-coded signs.

7.8 Natural Resources Conservation & Optimization

The rejects from the proposed washery shall be sold to interested consumers through e-auction or MoU route and the reject will be regularly disposed off to the prospective buyers on appropriate mode with due consideration to all statutory environmental stipulations.. The washery is also designed on zero discharge principle for conservation of water resources.

CHAPTER – 8

PROJECT BENEFITS 8.1 Introduction

The project relates to washing of coal to improve its quality so that it can be used for power generation. The construction and operation of the plant will also require development of infrastructure. A brief write-up on proposed development of such physical and social infrastructure is given below.

8.2 Physical Infrastructure (A) Access Road:

A new access road is proposed to connect the project site to existing road network in the area. Presently this road is katcha road. This road will be strengthened, widened and black topped. This road will also provide road access to the area.

(B) Power Network:

Power network will be extended to the project site for the construction & operation of the plant. This network will also facilitate distribution of power in the neighboring area.

8.3 Social Infrastructure The study area in which the project is located is comparatively developed in

terms of social infrastructure including health care facilities, education facilities etc. However the project proponent will develop the social infrastructure in the area under its Corporate Social Responsibility (C.S.R.) activities.

8.4 Employment Potential:

During construction of washery, the civil and structural work shall be

outsourced by BOM operator to sub-contractors and therefore the manpower will be provided by them (sub-contractor), depending on the work requirement at site. Hence semi-skilled and unskilled labor during construction phase and unskilled labor during operational phases of the project are proposed to be employed from amongst the local population. Business opportunity in Secondary & Tertiary sectors will increase.

8.5 Other Benefits: TO POWER PLANTS USING WASHED COAL:






VIII-2







8.6 Corporate Social Responsibility The Mines of Coal India and its subsidiaries are located in different parts of

the country spread in 8 States, and relatively in isolated areas with little contact to the outside society. Mining of coal has profound impact on the people living in and around the areas where the mines are established. The obvious impact of the introduction of any production activity in such areas change the traditional lifestyle of the original inhabitants and indigenous communities and also change the socio-economic profile of the area. Hence, the primary beneficiaries of CSR should be land oustees, PAP and those staying within the radius of 25 Kms of the Project. Poor and needy section of the society living in different parts of India should be second beneficiaries.

In the aforesaid backdrop, policy on Corporate Social Responsibility of CIL is

broadly framed taking into account the following measures: - a) Welfare measures for the community at large including employees and

their families, so as to ensure the poorer section of the Society derived the maximum benefits.

b) It will take care of land less and project affected persons. Proper

rehabilitation of the land oustees/displaced persons based on R&R policy separately formulated and the expenditure on R & R issues would be included in the Project Cost.

c) Contribution to the society at large by way of social and cultural

development, imparting education, training and social awareness, specially with regard to the economically backward class for their development and generation of income to avoid any liability of employment.

d) Protection and safeguard of environment and maintaining ecological

balance.

CHAPTER – 9

ENVIRONMENTAL COST BENEFIT ANALYSIS 9.1 GENERAL As per EIA notification Sept. 2006, the project is a category “A” project

requiring Environmental clearance. In compliance to statutory provisions, the project proponent approached MoEF, with prescribed Form-I and Conceptual Report for obtaining Terms of Reference for Environmental studies. MoEF issued TOR vide letter no. J-11015/67/2013-IA.II(M) dated 31.01.2014. A copy of TOR is enclosed at Annexure-8 of this report.

It may be seen from the TOR, that the scope of environmental studies for the

project does not require environmental cost benefit analysis for the project. Accordingly no environmental cost benefit analysis for the project has been carried out.

CHAPTER – 10

ENVIRONMENTAL MANAGEMENT PLAN 10.1 INTRODUCTION

The activities associated with project construction and project management are likely to have minimum adverse impact on various environmental attributes including air, water, noise, soil, socio-economic profile and bio-environment. To ensure that levels of pollutants do not exceed the limits prescribed by regulatory authorities, following exercise has been taken up.

● Baseline environmental data have been generated to describe the present

environmental quality in the study area. ● Likely impacts on environmental attributes due to project construction &

operation have been assessed using standard method. With above exercise, the anticipated levels of pollutants in environment have

been assessed. Environment pollution mitigation measures have been recommended to

minimize the impact & to limit them within prescribed level. These environmental mitigation measures are able to be implemental throughout the life of the project.

In addition, environmental parameters will be monitored on regular basis to

ensure that level of pollution is within the prescribed level. (The project proponent will submit several statutory reports relating to

project’s environment impact). From the above, it may be seen that environmental management of the

project during the full life will involve planning, design & implementation of several activities. This will require an exclusive budget and a dedicated organization.

10.2 ADMINISTRATIVE & TECHNICAL SETUP FOR ENVIRONMENT

MANAGEMENT

Environmental management of the project would need an exclusive budget for implementation of activities related to environment management of project. Item wise fund requirements are described below.

Water Pollution

The Washery is based on zero discharge system. Total water demand is 1273 m3/hr out of which 955 m3/hr is recycled water. Make-up water of 150 m3/hr shall be met from Gandhisagar/ Mitti quarry/any other mine sump of Balram OCP (BOCP). This includes 45 m3/hr for washery process, 23 m3/hr for Potable water, Sanitation etc. and 70 m3/hr for other industrial use (dust suppression, green belt maintenance etc.). 58 m3/hr water required for potable use, sanitation, spray, sprinkling shall be pre-treated in a water treatment plant of capacity 150 m3/hr. Additional capacity of the treatment plant will be utilized as per future needs. For detailed water balance Fig. no. 2.2 may be referred. Hingula washery, is based on Heavy Media Separation (HM Cyclone) and the washing circuit is a closed circuit with zero water discharge. Typical arrangement of Recirculation system in Hingula washery resulting in a Zero discharge is shown in Fig. 2.1.

11.3.3 Ambient air quality monitoring

Ambient air quality was monitored at 10 locations i.e. one in core zone and the remaining nine in buffer zone. A total of 24 samples (24-hrly) for Particulate Matter <10 (PM10), Particulate Matter <2.5 (PM2.5), Sulphur dioxide (SO2), Oxides of Nitrogen (NOx) Carbon Monoxide(CO), Ammonia (NH3), Ozone (O3), Benzene (C6H6), Lead (Pb), Benzo-pyrene (BaP), Arsenic(As), Nickel (Ni) and other heavy metals were collected.

11.3.4 Water quality monitoring

Representative water samples 9 nos. one in mine effluent, four in surface water and four from ground water i.e. dug well and tube well in buffer zone have been collected, preserved and transported to R&C Environmental Egg. Laboratory, Chennai and analyzed as per standard methods.

11.3.5 Noise levels recording

Noise levels were recorded by using CYGNET Integrated sound level meter (100X) from ten ambient air quality locations during day time and night time at an interval of four hours for one day for three months.

11.3.6 Soil quality monitoring

Soil samples from four locations, one in core zone, three in buffer zone were collected at depths of 30, 60 and 100 cms and analyzed for various physico-chemical and fertility parameters.

11.3.7 Socio-Economic Survey

The sample households have been selected by multistage sampling method. There are total of 41 villages within the 10 km radius and out of that 12 villages were surveyed for the household survey. The corezone is about 17 Hectares in barren/scrubland and no Households were found in core zone area.

11.3.8 BASELINE DATA ANALYSIS AND RESULTS

11.3.8.1 CONCLUSIONS OF BASELINE DATA

The following conclusions are drawn based on the baseline data collected at core and buffer zone area.

The wind velocity readings were ranging from 1.0 – 18.6 m/sec. Predominant wind was from north-east direction. The maximum temperature recorded was

42.0C and the minimum was 24.0 C. The relative humidity ranges from 16% to 93% and 20.3 mm rainfall was recorded during the study period.

In general, all the parameters monitored were found to be well within the prescribed limits of CPCB at Core zone. The PM10 values monitored at 6 locations out of 9 locations in buffer zone were found to be exceeding the limits. These may be due to the fugitive emission from the transportation and other allied mining activates in the buffer area. There are about 5 open cast


XI- 4

mines of MCL in operation in the study area. However, all other parameters except PM10 were found to be well within the limits.

The quality of mine water effluent is good even in untreated form. Further, the ground and surface water quality is also good and is well within the standard norms.

It is found that at day time noise level at 3 locations were slightly exceeding the limits. While comparing with standard norms for acceptable outdoor noise levels, all are other locations are found to be well within the prescribed limits.

The soil quality in the project area appears to be good and would support vegetation after suitable reclamation measures.

The major portion of core zone is about 17 Hectares in barren/scrubland and no household was found in core zone area.

Villages have been developed to the extent that Govt. health and primary education facilities are well available there.

Villagers are also availing power supply. People use two wheelers for purpose of travelling. In addition to some kachcha houses, most of other houses are made of concrete.

Villagers in the study area still cultivate their land in a traditional pattern and they are dependent mostly upon seasonal rain. The main occupations of the villagers are cultivation (agriculture) and non-agriculture work. Some of the villagers are employed under MCL also.

MCL runs various programmes in order to provide basic facilities like health, water, road and community hall etc. to the villagers.

MCL projects have directly or indirectly created various opportunities of employment in the region. A large number of villagers are engaged in such projects. These additional employments have big role in improving the living standards of villagers.

11.4 ANTICIPATED ENVIRONMENTAL IMPACT

The project activities will have impact on environmental attributes. Environmental impacts on following environmental attributes have been assessed.

● Ambient Air Quality ● Ambient Noise Level ● Surface Water Quality ● Topography, water drainage and land use. ● Bio-environment including Flora & Fauna ● Socio-economic environment. ● Storage of coal and washery reject ● Impact on immediate surrounding due to construction of washery 11.5 ENVIRONMENTAL POLLUTION MITIGATION MEASURES

Activities associated with construction and operation of the plant will have negative impact on environmental attributes. In order to minimize the negative impacts, pollution mitigation measures have been recommended. They are briefly mentioned below.

7 Rejects Stock


Dust suppression on the road shall be done by sprinkling of water. Monitoring the condition of transfer chutes and skirt boards and

replacing/repairing shall be done on regular basis during the normal inspection by the concerned persons along with the sectional heads.

Water spraying for dust suppression at temporary storage site for reject shall be done regularly.

Road inside the plant shall be paved to minimize the dust due to vehicle movement.

To minimize the generation of fugitive dust in conveyance of washery products Pipe conveyors/covered belt conveyors shall be used for their transportation.

Green belt (15m wide) of area 1.45 Ha in and around the washery site including around the conveyor, vacant places shall be developed to control dust emission.

Efforts for good housekeeping will minimize dust nuisance within the plant premises.

The crushers/pulverizers of the coal washeries shall be provided with enclosures fitted with suitable air pollution control measures.

Water spray arrangements shall be provided at all strategic coal transfer points, enclosures for conveyors etc.

11.5.2 Water Pollution Mitigation Measures

Sewage generated in service buildings, i.e. rest shelter, canteen, office etc.

would be treated in septic tank. The process of the proposed washery is based on closed water circuit system.

All the water fed into the system will be collected after use and re-circulated, after treatment, in various units and no effluent will be allowed to escape into the natural drainage system. Moreover, washery circuit envisages dewatering system like belt press filter & High Frequency Screens for efficient recovery of solids from the slurry. The filtrate water from these equipment will be recycled back to the system to ensure closed water system. The underflow of Radial


XI- 6

thickener, in case of emergency, may be fed to slime ponds for settling & natural drying and subsequent reclamation of the dried fines. The overflow water of slime ponds will be pumped back for re-use in the process. Thus, the operation of the washery will not cause any pollution to the local source of water.

Provision of surface run-off settling pond shall also be provided. Garland drain(s) around the stockpiles and other process areas shall collect and carry the run off to settling pond. Overflow water of the settling pond shall be utilized for plant operation etc. Hence, there will be no impact on groundwater and surface streams.

Washery will be designed for zero discharge. However, in case of emergency underflow from thickener shall be treated in 03 Nos of slime ponds of size 100m x 6m x 2.5 m (each) and treated effluent shall be reused.

Total water demand is 1273 m3/hr out of which 955 m3/hr is recycled water. Make-up water of 150 m3/hr shall be met from Gandhisagar/Mitti quarry/any other mine sump which are approximately within 3 KM from the washery site. Hence, groundwater or surface water shall not be utilized for any industrial use in the washery.

11.5.3 Noise Pollution Mitigation Measures

The following measures therefore, have been envisaged to reduce the noise level to the minimum and to protect the workers from noise hazard.

Use of equipment with arrangements for absorbing the operational noise. Use of insulated cabins for operators Use of rubber/ polymer liners in chutes and hoppers Use of ear muffs by workers in the zone of high noise source (if any) 15 meter wide green belt around the Washery and service building area (1.45

Ha). Routine preventive maintenance of equipment/HEMM to minimize noise

generation at source. Regular maintenance with prompt replacement of worn-out parts/ liners etc. Operational / work zone – not to exceed 85 db (A) Leq for 8 hours exposure Use of silencer for equipments such as diesel sets and air displacement

equipment Regular monitoring of noise levels at various points.

11.5.4 Bio-Environment Mitigation Measures

Proposed Hingula washery will be located at Balaram Opencast Project in Hingula Area in the Talcher Coalfield of MCL and the land is in possession of MCL. The major portion of total 17 Ha of land required for Hingula washery is barren/scrubland and it does not involve any forest land.

11.5.5 Mitigation Measures for Socio-Economic Profile

During construction of washery, the civil and structural work shall be

outsourced by BOM operator to sub-contractors and therefore the manpower will be provided by them (sub-contractor), depending on the work requirement at site. Hence semi-skilled and unskilled labor during


XI- 7

construction phase and unskilled labor during operational phases of the project are proposed to be employed from amongst the local population.

Employment opportunity and access to other amenities such as education, health care facilities for local people

Socio-economic survey conducted and the analysis to identify areas of corporate contribution to improve quality of life

Project specific CSR initiatives The land is free from human habitation. Thus construction and operation of

plant will not create any R&R issue. However, the project proponent (MCL) will undertake certain socio-economic development schemes under CSR programme.

11.8 ENVIRONMENT MANAGEMENT PLAN

The activities associated with project construction and project management are likely to have minimum adverse impact on various environmental attributes including air, water, noise, soil, socio-economic profile and bio-environment. To ensure that levels of pollutants do not exceed the limits prescribed by regulatory authorities, following exercise has been taken up:

●Baseline environmental data have been generated to describe the

present environmental quality in the study area. ●Likely impacts on environmental attributes due to project construction &

operation have been assessed using standard method.

With above exercise, the anticipated levels of pollutants in environment have been assessed.

Environment pollution mitigation measures have been recommended to minimize the impact & to limit them within prescribed level. These environmental mitigation measures are able to be implemental throughout the life of the project. In addition, environmental parameters will be monitored on regular basis to ensure that level of pollution is within the prescribed level. The project proponent (MCL) will submit several statutory reports relating to project’s environment impact. From the above, it may be seen that environmental management of the project during the full life will involve planning, design & implementation of several activities. This will require an exclusive budget and a dedicated organization.
