DETAILS OF THE PROCESS

Coal from the gantry is crushed in a crusher and conveyed to coal storage bunkers through a system of conveyor belts, crusher and vibrating screens and is fed to the furnace. The coal burns inside the furnace so as to maintain a furnace temperature of 880-900°C.

De-mineralised water from the storage tank is pumped to the boiler with the

aid of boiler feed pump. The boiler feed water through an economizer enters the steam drum, mud drum and water walls where it is heated and converted to saturated steam. The saturated steam is then heated to a temperature of 540°C in the super heaters and carried to common steam header. Hot air from the boiler furnace is drawn by an induced draft fan

through economizer, air heater and ESP and vented out through a chimney of 275 meters height.

The steam from the main steam header at 150 Kg/cm2 and 540°C temperature is taken to the turbo–generators. After rotating the turbine the exhaust steam is condensed in the condensers and the condensed water is pumped to the de-aerator and fed back to the boilers.

Project Cost: The total cost of project is 5045 Crores

RESOURCE REQUIREMENT

Water: The source of cooling water will be from the Banas which is about 40

km from the proposed site. The irrigation department of MP government has granted permission for withdrawing of water for the proposed unit. A


dedicated intake system and pipeline shall be laid for this purpose. Water requirement for 4 x 300 MW units is 4400 m3/hr. Fuel: Indian coal of E / F Grade has been considered as main fuel. Coal shall be transported from Northern Coalfields which are approximately 90 km through rail –N- road mode of transportation. Coal requirement for 4 x 300 MW units considering GCV of 3600 kcal/kg & 85 % PLF is as follows.

? Coal requirement per hour: 706 Tonnes Start-up Fuel

The annual requirement of secondary fuel - LDO/HFO used for cold start up with initial warm up is estimated to be around 12000 KL/annum. It shall be stored in 2 tanks of 500 KL with considering 30 days storage. Land Requirement The land requirement for the project is as follows

Sr. No. Details Area in Acres

1 Land for power plant excluding ash disposal area. 125 2 Land for Green belt development at plant site. 300

3 Land for coal storage yard, Handling and Marshalling Yard and RoW for transport of materials/water

200

4 Land for water reservoir 50 5 Land for Colony & Township and Roads 75 6 Land for Ash Dyke 200 7 Total land required for power plant 950

Infrastructure At present no rail link is existing for the transportation of coal from mines to site. The nearest railway siding is at Bhadhura, which is 4 km away. Company is in the process of obtaining necessary clearance for laying a rail

line to site. Hence infrastructure requirement for transportation for initial period is limited to roads. Apart from this, facilities for unloading, weighing and storage will be established at plant site.

BASELINE ENVIRONMENTAL QUALITY

Methodology of the Study

Keeping in view the nature of activities, the process of power plant and various environmental guidelines, the area covering a radial distance of 10 Km from the centre of the plant site was selected as study area for the


purpose of EIA study. To establish baseline status of air, water, noise, land, biological and socio-economic environment in the study area, extensive field studies were undertaken in and around power plant during the winter season (December 2008 to February 2009)

Climate

The climate of the area is tropical monsoon type with three distinct seasons as hot and dry summer/premonsoon (March -May), monsoon (June-October), and winter (November - February). The climate of the area is dry during the period of November to the beginning of June while during rainy season the atmosphere is very humid. The average annual rainfall varies from 1000-1200 mm, peaks in the months of July and August. May is the hottest month with the mean daily maximum temperature being about 41°C. January is generally the coolest month with mean daily maximum temperature at about 9°C.

Air quality was monitored at eleven numbers of air-quality stations and it was observed that the levels of SPM, RSPM, SO2 and NOx are well within the standards prescribed by CPCB. Average values of pollutants concentrations are given below

Sr. No. Sampling Location Name Average Concentrations of Pollutant in µg/m3 SPM RSPM SO2 NOx 1 Project Site 124 50 6 9 2 Amakholi 118 45 7 12 3 Parasi 123 48 7 10 4 Ser 134 55 8 11 5 Khajuriha 129 49 7 13 6 Nidhpuri 147 60 9 13 7 Bhumka 135 52 7 11 8 Nigri 137 53 10 14 9 Katai 133 50 6 9 10 Chhamrachh 131 47 8 12 11 Bajbal 113 35 8 12

Noise levels were monitored at ten locations within the study area. The day time noise levels at all the sampling locations were observed in the range of 47 to 55 dB(A) except at Parasi (63 dB(A)). The night time noise levels were in the range of 40 to 49 dB(A). The levels were well within the permissible limits for residential areas

Water samples of both surface (5Locations) and ground water (6Locations) sources, were analyzed and compared with IS: 10500 limits. The water from surface water source is found to be fit for drinking purposes.


Biological Environment: The study area mostly comprises of rural area. The area includes few villages comprising of agricultural and barren land where most of the vegetation is aggregated on agricultural bunds and forest area. Common flora and faunal species are found in the study area. No national park, Sanctuary, elephant/tiger reserve, migratory routes falls within the study area

Socio Economic Environment: The study area comprises of 45 villages.

Total population of study area is 48,778 approximately. The nearest human settlement is the village Kamchar, Musmuri and Bhumka. Literacy rate of study area is 48.8%. The percentage of male and female population is 64.93% and 32.68% respectively. The scheduled Caste and Scheduled tribe population is 9.30% and 33.36% of the total population respectively.

Economic conditions of people are moderate to poor. Most of the families are living in kachha house. Toilet facilities are not available in most of the houses in near by villages of project site.

Waste Water Disposal In the Power Plant: The waste water collected from

cooling tower, boilers, ash handling, domestic waste and D.M. plant to the tune of 920 m3/hr is collected in neutralization-cum-settling tank and then to the collection-cum-storage tank from where it is further used for fly ash wetting, dust suppression in coal yard, as fire hydrant and for gardening.

Land Use Pattern: Location around the project sites studied is scarcely

populated except in some clusters and a part of the terrain is agricultural land. Scattered villages like, Musamudi, Bhumka are located within the project area. The land use pattern around 10 Km radial distance of the power plant is given below

Sr. No. Land Use Area

1. Forest 9425 30.0

2. Irrigated Land 5771 18.37

3. Un- irrigated land 8681 27.63

4. Cultivable waste land 2513 8.0

5. Not available for cultivation 5026 16.0

6 Total 31416 100

Soil Quality: The pH of soils was in the range of 6.7 to 7.5. The EC of soils were in the range of 146 to 348 µS/cm. The CEC analysis of the soil samples


were in the range of 10.43 to 15.5 meq/100gm. N, P, K values at all the locations shows that soils are moderate fertile.

Impact Assessment: "Environmental Impact" can be defined as any alteration of environmental conditions or creation of a new set of environmental conditions, adverse or beneficial, caused or induced by the action or set of actions under consideration.

IDENTIFICATION OF IMPACTS

Air Environment:

The prediction of impact of stationary sources on the ambient air quality has been calculated using Oak Ridge Air Quality Index (ORAQI). For calculating the index, baseline data collected were analyzed and maximum concentration was determined for three pollutants viz. SPM, SO2 and NOx. The results on evaluation of Oak Ridge Air Quality Index (ORAQI) show that there is no impact on surrounding area.

Air quality modeling has been done to assess the air quality after project implementation using ISCST3 model. GLC are predicted for SO2 and SPM.

Predicted concentrations at all AAQMS for SO2 and SPM are within the stipulated AAQMS set by MOEF. Hence, ambient air quality will not be degraded after the execution of proposed ultra mega power plant

Water Environment: The total water requirement of the Power Plant with associated facilities will be 4400 m3/hr. The proposed power plant will meet

its process water requirement from Banas river. There will not be any impact on surface or ground water characteristics due to power plant. The surface and ground water characteristics of the samples monitored within the study area are well within the permissible limits.

The treated effluents for discharge would meet the MINAS standards. The quality of the treated wastewater will be suitable for horticulture/irrigation

Land Use: The proposed Power plant is not expected to change the land use, soil characteristics and landscape in the region out side the power plant area.

Noise Environment: The impact of noise generated from the proposed project on its workers is expected to be insignificant except for the employees working near compressors, FD fans, PA fans, ID fan, turbines and Blower. For these sources the workers can be protected using earplugs and


arranging their duties in cycles. The impact of noise generated due to proposed project is insignificant on the human settlements in the area.

Biological Environment: The impact on terrestrials and aquatic ecology due to the proposed the power plant is insignificant. With the green belt development around the plant as suggested in EMP the terrestrial environment of the region will be having positive improvement and will further mitigate fugitive emissions as well as attenuated noise impact.

Ecology: As the study area does not provide habitation to any rare and endangered species of flora and fauna, impact on ecology will be mainly due to removal of green cover. This will be compensated, by the tree plantation programs being implemented by the management of the Power plant.

Socio-Economics: The impact of the project on socio-economic status of the

region would be predominantly positive, if proper implementations of the measures suggested in the EMP are made.

Resettlements and Rehabilitation: Musamudi and Bhumka village are comes under project area of 950 acres. Approximately 66 families will be affected due to proposed project. Detailed rehabilitation and resettlement plan for the same has been prepared. Affected peoples will get adequate compensation as per the RR policy and central government guidelines

Overall Impact: The overall impact of the power plant project is beneficial as the impact on the air, noise, water, land and biological environments are

not very significant and the socio-economic benefits are predominantly positive.

RISK ASSESSMENT & DISASTER MANAGEMENT PLAN: The risk assessment helps one in taking care of probable hazards on account of faulty / defective operations of various plants, machinery, equipment, etc. Such risk

assessment proves helpful in foreseeing the risks involved in various operations to prevent the likely accidents.

As far as the power plant is concerned, it involves risk both in constructional phase and operational phase of the project Hazardous Fuel oils and Chemical Storage Facilities: The power plant operation involves extensive use of various lubricants and limited use of fuel oils. The fuel oils usually used are light diesel oil (LDO), furnace oil (FO), low sulphur heavy stock oil (LSHS) etc. Necessary risk analysis shall very well be done and the storage facilities shall be suitably developed. Storages of acids and alkalies viz.

hydrochloric acid, sulphuric acid, caustic soda, etc. should be designed


properly. Various gases used in power plant should be stored in the suitably designed cylinders and the cylinders are placed in the proper positions.

Occupational Safety: Since the process do not call for release of any

inflammable or toxic substances, it is considered desirable to provide a safe working environment to the operational staff. Suitable casings to all the moving parts will be provided and perfect encasing to the electrical installation will be made to prevent any electrical accident.

Fire protection System: The power plants which are operating on various kinds of fossil-fuels such as coal, oil, gas, etc. are prone to fires. The fires are of various kinds and these need to be quenched by way of resorting to various protection systems. The plant area shall be provided with smoke detection system which could detect any kind of smoke likely to arise on

account of fires.

Protective equipments for working personnel: In order to take care of the working personnel, they would be provided with various protective devices, which shall broadly comprise respirators (face pieces, walls, sweat traps,

head bands, filters, etc.), goggles, rubber gloves, gum shoes, etc

DISASTER MANAGEMENT PLAN: Disaster is an undesirable occurrence of events of such magnitude and nature, which adversely affects production and/or causes damage to environment. Risk assessment forms an integral part of disaster management and any realistic “Disaster Management Plan”

could only occur through a scientific risk assessment studies and involves 1) Requirement of fire extinguisher at all the fire prone sides. 2) Mock drill should be carried out periodically for emergency preparedness. 3) Effective communication systems at all the parts of the plant should be maintained.

Risk Analysis: Risk analysis consists of two parts viz. i) Risk identification and ii) Risk assessment.

Risk Assessment: Risk assessment techniques are:

1) Hazard and Operatability Study (HAZOP) 2) Fault Tree Analysis (FTA) 3) Monte Carlo Simulation 4) Safety Audits 5) Safety Indices 6) Above risk

assessment techniques are discussed in the subsequent paragraphs.

Hazard and Operatability Study (HAZOP) study involves identification of Hazards or operatability problem of the process and envisages possible deviations from normal operating conditions.


PROCEDURE FOR FIRE / GAS LEAKAGE CONTROL: When fire on account of gas leakage is noticed, it is desirable to take following measures:

a) Break the nearest fire-glass.

b) Immediately inform to concerned plant control room.

c) Follow the instructions of control room.

d) Act to control the incident as per the instructions.

e) Reach to the assembly point, located at right angle to be wind direction.

ENVIRONMENTAL MANAGEMENT PLAN: The proposed power plant shall have two significant phases. The first phase shall be the constructional phase, and the second phase i.e. operational phase,

EMP for Constructional phase: The constructional phase comprises various activities which are rather transient in nature and prevail for shorter duration. The following measures are considered desirable:-

Necessary facilities such as sanitation, water supply, rest rooms, etc. shall be provided for the construction staff.

The site excavation, blasting, movement of earthen materials, etc. shall be planned and executed properly to avoid any nuisance / hazard.

The site shall be provided with suitable trenches for draining of the rain water and construction water effectively. The electrical equipments and instruments shall be properly and carefully handled. The fuels such as

petrol, diesel, the lubricating oils, various gases, paints, varnishes, etc. shall be properly stored as per the standard practices.

EMP for Operational phase: Various standard practices have been evolved to manage the power plant operations efficiently to cause least possible concern to the environment.

Coal Handling Scheme: In a typical coal based power plant, the stack emissions are obviously expected to comprise SPM, SO2, NOX. Similarly, the fugitive emissions on account of coal dust and ash particles are very common and rather unavoidable. However, in present power plant

practices, the coal dust emissions are taken care of by way of providing dust suppressing equipments and sprinkling of water everyday.

Ash handling system: The percentage of ash in coal has a bearing on the quantum of ash produced. Fly ash is collected in the closed hoppers; the

total quantity of fly ash generated will be about 318 TPH. Fly ash will be


used for the manufacture of cement and will be transported with the help of bulkers.

Flue gases: The plant shall be provided with electrostatic precipitators having high efficiency (above 99.98%) for collection of the fly ash that would be produced from the process of coal combustion in boiler furnace.

Water Pollution: During operational phase, the likely sources of water pollution and the measures to be taken for their managements are described hereunder

Effluents from water treatment plant: The effluents from cation/anion resins are combined with the filter back wash in the neutralizing pit and by way of giving additional treatment as may be necessary, the effluents are

treated to make them hazard free.

Various drains in the plant area: The storm water (rain water) collected from the open areas is let through the open channels and conveyed to the storm water drain which in turn lets out the water into a suitable low lying area. For this purpose, suitable slope shall be provided to avoid any type of flooding in the power plant. The roof top rainwater harvesting will be done to recharge the underground water.

Noise Pollution: The power plant process involves various machineries and equipments and while in operation, these machineries tend to produce noise, which is rather unavoidable. Efforts are always made to maintain minimal possible noise levels on all these accounts. The endeavours would be aimed at maintaining the noise levels below 85-90 dB(A) or even lesser at a distance of about 1.5 meters from the equipment, using stable foundation for machines and appropriate noise absorbing sheets in control cabins.

Sewage disposal: The disposal of the domestic sewage from the plant would be through the closed drainage system sewage treatment plant.

Biological Environmental Management Plan: Efforts shall be made to avert any adverse impact on flora and fauna in the area of proposed plant or at least to minimise the impact to the possible extent. To this effect, Green belts (30 meter width) shall be suitably developed around the boundary of the power plant with selected locally grown plant species.

Socio-economic Environment: In order to provide employment to the local people, efforts shall be made to employ the work force from the surrounding area. Various social activities to be undertaken by the project shall be confirming to the local needs and these activities shall be planned


in coordination with local representatives of the public, government officials.

IMPACTS ON LAND ENVIRONMENT: To minimize disruption of soil and for conservation of topsoil, the topsoil should be taken out and stacked separately and stockpile it. Topsoil should be utilized for landscaping activity. Other measures, which would be followed to prevent soil erosion and contamination include: 1) Maximize use of organic fertilizer for landscaping and green belt development. 2) Selection of the plant species should be on the basis of their adaptability to the existing geographical conditions and the vegetation composition of the region. 3) The species should be fast growing and providing optimum penetrability. 4) The species should form a dense canopy. 5) Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces.
