EXECUTIVE SUMMARY 1.0 Introduction M/s. Indian Oil Corporation Limited (IOCL) is a government of India enterprise with a Maharatna status, and a Fortune 500 and Forbes 2000 company. Incorporated as Indian Oil Corporation Ltd. on 1st September, 1964 Indian Oil and its subsidiaries accounts for nearly half of India's petroleum products market share, 35% national refining capacity (together with its subsidiary Chennai Petroleum Corporation Ltd., or CPCL), and 71% downstream sector pipelines through capacity. The IOCL Group owns and operates 11 of India's 23 refineries with a combined refining capacity of 80.7 MMTPA (million metric tonnes per annum). IOCL is a premier public sector company in the Oil & Gas Sector and is engaged in the business of refining and retailing of petroleum products including LPG in the country. It is the leading Indian corporate in the Fortune 'Global 500' listing, ranked at the 137th position in the year 2018. IndianOil's network of over 48,000 customer touch-points reaches petroleum products to every nook and corner of the country. These include more than 27,000 petrol & diesel stations, including 7000 Kisan Seva Kendra outlets (KSKs) in the rural markets. Over 10,000 fuel stations across the country are now fully automated. The Corporation has a 65% share of the bulk consumer business, and almost 6650 dedicated pumps are in operation for the convenience of large•volume consumers like the defence services, railways and state transport undertakings, ensuring products and inventory at their doorstep. They are backed for supplies by 125 bulk storage terminals and depots, 110 aviation fuel stations and 91 LPG bottling plants. Indane LPG cooking gas reaches the doorsteps of 12.69 crore households in about 6250 markets through a network of 10,200 distributors. IndianOil’s world-class SERVO lubricants have presence in 27 markets worldwide. Riding on 50 successful years as the market leader, the Aviation Service commands a 61% market share in aviation fuel business. IndianOil is the Supplier of Choice for aviation fuel to the Indian armed forces and over 150 national and international flag carriers, private airlines based in India and abroad.

2.0 Project Description The existing petroleum market of Ullundurpet and surrounding area is being fed from petroleum storage locations existing at Chennai, Trichy and Shankari. The Chennai-Trichy-Madurai Pipeline (CTMPL) of IOCL is already having an intermediate pump station at Asanur, Tamil Nadu. By providing a pipeline Tap of Point (ToP) at Asanur which is at a distance of 220 km from Chennai and 150 km from Shankari, movement of petroleum products by road would be reduced considerably. This would result in considerable saving in consumption of fossil fuel, saving in logistic cost to Govt. exchequer and reduce emission / noise pollution by avoiding movement of petroleum products from far off refinery locations. Details of product wise tankage are given in Table 1.

EIA report for the proposed Petroleum Storage Terminal of storage capacity 80870 m3 of IOCL at Sy No 365/4 (pt) at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State need to be worked out for minimizing the loss of soils, by way of storage of topsoil and then again laying it back after the completion of the construction of terminal. Impacts on ambient air would mainly be due to dust emissions and movement of vehicles. However, these impacts would be short-term in nature. Impacts on ambient air during operational phase would be due to emissions from DG set stacks and vehicles which will be very negligible The detailed environmental management plan has been presented in the main report. IOCL will ensure that all the statutory norms, emissions norms for air, water, and noise shall be maintained during the construction and operation phases and in line with the proposed EMP. 5.0 Environmental Monitoring Programme It is imperative that the IOCL should set up regular monitoring locations to assess the environmental health in the post period. A post study monitoring programme is important as it provides useful information on the following aspects.

 It helps to verify the predictions on environmental impacts presented in this study.

 It helps to indicate warnings of the development of any alarming environmental situations, and thus, provides opportunities for adopting appropriate control measures in advance.

6.0 Additional Studies Hazard Identification and Consequence Assessment Hazards are identified for release of MS, HSD, Bio-Diesel and Ethanol for scenarios of catastrophic rupture of storage tank at proposed site. Consequence analysis of all possible containment scenarios was carried out using DNV Technical Software (PHAST). No domino effect envisaged as all tanks are adequately spaced and heat or pressure wave is limited to dyke area. 7.0 Project Benefits

 The project will improve supply of the HSD, MS blended with Bio-Diesel and Ethanol respectively in Tamil Nadu which is vital for economic growth as well as improving the quality of life.  The project shall provide employment potential under unskilled, semi-skilled and skilled categories. The employment potential shall increase with the start of construction activities, reach a peak during construction phase and then reduce with completion of construction activities. During operation phase also there will be employment opportunities, mainly in service sector, although its magnitude will be much less.

 The direct employment opportunities with IOCL are extremely limited and the opportunities exist mainly with the contractors and sub-contractors. These agencies will be persuaded to provide the jobs to local persons on a preferential basis wherever feasible.

CHAPTER 1. INTRODUCTION

1.1 Introduction of Project & Project Proponent

M/s. Indian Oil Corporation Limited (IOCL) is a government of India enterprise with a Maharatna status, and a Fortune 500 and Forbes 2000 company. Incorporated as Indian Oil Corporation Ltd. on 1st September, 1964 Indian Oil and its subsidiaries accounts for nearly half of India's petroleum products market share, 35% national refining capacity (together with its subsidiary Chennai Petroleum Corporation Ltd., or CPCL), and 71% downstream sector pipelines through capacity. The IOCL Group owns and operates 11 of India's 23 refineries with a combined refining capacity of 80.7 MMTPA (million metric tonnes per annum).

IOCL is a premier public sector company in the Oil & Gas Sector and is engaged in the business of refining and retailing of petroleum products including LPG in the country. It is the leading Indian corporate in the Fortune 'Global 500' listing, ranked at the 137th position in the year 2018. Indian Oil's network of over 48,000 customer touch-points reaches petroleum products to every nook and corner of the country. These include more than 27,000 petrol & diesel stations, including 7000 Kisan Seva Kendra outlets (KSKs) in the rural markets. Over 10,000 fuel stations across the country are now fully automated.

The Corporation has a 65% share of the bulk consumer business, and almost 6650 dedicated pumps are in operation for the convenience of large volume consumers like the defense services, railways and state transport undertakings, ensuring products and inventory at their doorstep. They are backed for supplies by 125 bulk storage terminals and depots, 110 aviation fuel stations and 91 LPG bottling plants.

Indane LPG cooking gas reaches the doorsteps of 12.69 crore households in about 6250 markets through a network of 10,200 distributors. Indian Oil’s world-class SERVO lubricants have presence in 27 markets worldwide. Riding on 50 successful years as the market leader, the Aviation Service commands a 61% market share in aviation fuel business. Indian Oil is the Supplier of Choice for aviation fuel to the Indian armed forces and over 150 national and international flag carriers, private airlines based in India and abroad.

The Existing petroleum market of Ulundurpet and surrounding area is being fed from petroleum storage locations existing at Chennai, Trichy and Shankari. The Chennai-Trichy-Madurai Pipeline (CTMPL) of IOCL is already having an intermediate pump station at Asanur, TN. By providing a pipeline ToP at Asanur which is at a distance of 220 km from Chennai and 150 km from Shankari, movement of petroleum products by road would be reduced considerably. This would result in considerable saving in consumption of fossil fuel, saving in logistic cost to Govt. exchequer and reduce emission / noise pollution by avoiding movement of petroleum products from far off refinery locations.

A drainage system is the pattern formed by the streams, rivers, and lakes in a particular drainage basin. Drainage basins can be described by the order of streams within them. Streams that have no tributaries (or streams flowing into it) are termed first order streams. When the first order streams join together, they become second order steam. Two second order streams join to form third order stream and so on for forth and further orders. However, a stream may have a tributary with a lower order without becoming a higher order stream. Strahler method of ordering was used for giving order to drainage. Drainage map Figure 3.3of a study area shows highest order of drainage as 6th order i.e. Manimuktha River. Gomuki river on West side join to Manimuktha river. Drainage pattern within 10 km radius around project site shows dendritic type of drainage pattern.

3.3.2 Hydrogeology & Geology

Geomorphology and Soil types Geomorphology The residual hills and denudational hills are common in Tirukoilur, and taluks. Structural hills are noticed in the western part of the district. The shallow pediments and buried pediments are common in the central part of the district. Coastal areas are having older and younger flood plains and also beach landforms at places. The ground slope is gentle towards coast. The valley fill near Villupuram is thick, which forms main ground water discharge zone. Lineaments are restricted to parts of Kallakurichi and Sankarapuram areas and productive fractures are noticed in select pockets. The crystalline sedimentary contact fault is having sympathetic fractures in hard rocks but mostly they are dry fractures.

Soils The soils in the district are mostly forest soils and red soil. Alluvial soils are found in eastern side bordering coast. Black soils are confined to low ground in select pockets in . Ground Water Scenario Hydrogeology Villupuram district is underlain by crystalline metamorphic complex in the western part of the district and sedimentary tract in eastern side (Plate-II). The thickness of sediments exceeds 600m near southern part of the district. Groundwater occurs under phreatic and semi–confined conditions in consolidated formations, which comprises weathered and fractured granites, gneisses and charnockites whereas in unconsolidated sedimentary rocks the groundwater occurs in phreatic, semi-confined conditions in Vanur sandstone, Kadapperi kuppam formation and Turuvai limestone. The district is having rocky outcrops in major part of Kallakurichi, Sankarapuram and Tirukoilur taluks. The weathering is highly erratic and the depth of abstraction structures is controlled by the intensity of weathering and fracturing. The depth of wells varies from 6.64 to 17 m bgl and water levels in observation wells tapping shallow aquifers varied from 0.74 to 9.7 m bgl during pre-monsoon (May 2006) and it varies from 0.7 to 4.45 m bgl during post monsoon (January 2007). During pre-monsoon, the depth to water levels in the range of >2 to 5 m bgl in major part of the district, in the range of >5 -10 m bgl in western and southeastern parts of the district and range of 0-2 m bgl were recorded in two isolated pockets.

During post monsoon the depth to water levels range of >2 to 5 m bgl exists in major part of the district, range of 0 - 2 m bgl prevails in central and northeastern parts of the district and range of >5 - 10 m bgl were recorded in two isolated pockets in the southwester and north western parts of the district (fig-2). The depth to piezometric surface ranged from 2.8 to 11.25 m bgl during Pre monsoon and 0.5 to 6.35 m bgl during post monsoon. The ground water is being developed my means of dug wells, bore wells and tube wells. The diameter of the well is in the range of 7 to 10 m and depth of dug wells range from 15 to 18 m bgl depending on the weathered thickness and joints. The dug wells yield up to 1 lps in summer months and few wells remains dry. The yield is adequate for irrigation for one or two crops in monsoon period. The yield of bore wells in favourable locations vary from <1 to 6 lps. The valley fills, intersection of lineaments, particularly,

in the western part along the foot hills of Kalrayan hills are reported to have potential pockets suitable for dug wells and bore wells. The area of contact between crystalline and sedimentary formations has variable yield prospects. The cretaceous formations are very compact and yield prospects are low. The dug wells of 6 m diameter and 10 m bgl depth in sandy tracts give about 3.5 lps. The yield of tube wells in the sedimentary formation ranges from 2.4 to 37 lps. Long-term fluctuation The long –term water level fluctuation for the period of (1998-2007) indicates rise in water level in the range of 0.003 to 0.63 m/year whereas the fall in the water level ranges between 0.014 and 0.31 m /year.

Aquifer Parameters The transmissivity values of fractured aquifers range from < 1 to 141 m2 /day and storativity varies between 2.84x10.5-5 and 8.9x10-3. The transmissivity of sedimentary formation varies from 21 to 748m2 /day and storativity is in the order of 2.75x10-3. Drainage The Ponnaiyar, the Malattar and the Gadilam are the major rivers draining the district. The Ponnaiyar River flows from northwest to east in the district. The Manimukta nadi originates in Kalrayan hills and drains the southern part of the district. The Pambaiyar and the Varaganadhi originate in the uplands of the district and join Bay of Bengal. The Varaganadhi is also known as the Gingee River and drains the parts of Gingee and Vanur taluks of this district. The Malattar and Gadilam rivers also originate in the uplands 2 within the district and flow eastwards to . All the rivers are ephemeral in nature and carry only floodwater during monsoon period. The drainage pattern is mostly parallel to sub parallel and drainage density is very low. There are small reservoirs across rivers namely Gomukha, Vedur and Mahanathur.

3.4 Meteorological Data

The meteorological parameters play a vital role in transport and dispersion of pollutants in the atmosphere. The collection and analysis of meteorological data, therefore, is an essential component of environmental impact assessment studies. The long term and short term impact assessment could be made through utilization and interpretation of meteorological data collected over long and short periods. Since, the meteorological parameters exhibit significant variation in time and space, meaningful interpretation can only be done through a careful analysis of reliable data collected very close to the site.

Ambient air at the monitoring location is sucked through a cyclone. Coarse and non-respirable dust is separated from the air stream by centrifugal forces acting on the solid particles and these particles fall through the cyclone's conical hopper and get collected in the sampling cap placed at the bottom. The fine dust (<10 microns) forming the PM10 passes the cyclone and is retained on the filter paper. A tapping is provided on the suction side of the blower to provide suction for sampling air through a set of impingers for containing absorbing solutions for SO2 and NOx. Samples of gases are drawn at a flow rate of 0.2 liters per minute.

PM10 has been estimated by gravimetric method. Modified West and Gaeke method (IS-5182 part-

II, 1969) has been adopted for estimation of SO2 and Jacobs-Hochheiser method (IS-5182 part-VI,

3.6 Noise Noise in general is sound, which is composed of many frequency components of various loudness distributed over the audible frequency range. The most common and universally accepted scale is the A weighted scale which is measured as dB (A). This is more suitable for audible range of 20 to 20,000 Hz and has been designed to weigh various components of noise according to the response of a human ear. The environmental assessment of noise from the industrial activity, construction activity and vehicular traffic can be undertaken by taking into consideration various factors like potential damage to hearing, physiological responses, and annoyance and general community responses.

3.6.1 Objective The main objective of monitoring of ambient noise levels was to establish the baseline noise levels in different zones. i. e. Residential, Industrial, Commercial and Silence zones, in the surrounding areas and to assess the total noise level in the environment of the study area.

3.6.2 Methodology

 Identification of Sampling Locations A preliminary reconnaissance survey was undertaken to identify the major noise sources in the area. The sampling location in the area was identified considering location of industry, commercial shopping complex activities, residential areas with various traffic activity and sensitive areas like hospital, court, temple and schools also near the railway track for railway noise. The noise monitoring was conducted at eight locations in the study area during monitoring period. 10 sampling locations were selected for the sampling of noise.

 Equivalent sound pressure level (Leq) The sound from noise source often fluctuates widely during a given period of time. Leq is the equivalent continuous sound level, which is equivalent to the same sound energy as the actual fluctuating sound measured in the same time period.

 Instrument used for Monitoring Noise levels were measured using an Integrating sound level meter manufactured by Cygnet (Model No. 2031). It had an indicating mode of Lp and Leq. Keeping the mode in Lp for few minutes and setting the corresponding range and the weighting network in “A” weighing set the sound level meter was run for one hour time and Leq was measured at all locations. There are different types of fields for measuring the ambient noise level, e categorized as free field, near field and far field.

 Free Field The free field is defined as a region where sound wave propagates without obstruction from source to the receiver. In such case, the inverse square law can be applied so that the sound pressure level decreases by 6dB (A) as the distance is doubled.  Near Field The near field is defined as that region close to the source where the inverse square law does not apply. Usually this region is located within a few wavelengths from the source.  Far Field The far field is defined as that region which is at a distance of more than 1-meter from the source.

3.6.3 Method of Monitoring and Parameters Measured

Noise monitoring was carried out continuously for 24-hours with one hour interval. During each hour parameters like L10, L50, L90 and Leq were directly computed by the instrument based on the sound pressure levels. Monitoring was carried out at ‘A’ weighting and in fast response mode.

The important parameters to be measured are Leq, Lday, and Lnight. Leq: Latest noise monitoring equipments have the facility for measurement of Leq directly. However, Leq can also be calculated using the following equation: 2 Leq (hrly) = L50 + (L10 - L90) / 60

L10 (Ten Percentile Exceeding Level) is the level of sound exceeding 10% of the total time of measurement.

L50 (Fifty Percentile Exceeding Level) is the level of sound exceeding 50% of the total time of measurement.

L90 (Ninety Percentile Exceeding Level) is the level of sound exceeding 90% of the total time of measurement.

Lday: This represents Leq of daytime. Lday is calculated as Logarithmic average using the hourly Leq’s for day time hours from 6.00a.m to 10.00p.m

Lnight: This represents Leq of night time. Lnight is calculated as Logarithmic average using the hourly Leq’s for nighttime hours from 10.00p.m to 6.00a.m.

3.7 Water Environment 3.7.1 Ground Water Hydrology Hydro-geologically the weathered and fractured zones of crystalline constitute the predominant hydro-geological units. Groundwater occurs under phreetic condition in the weathered horizons. Highly weathered and jointed granitic gneisses occurring the undulating plains form the potential aquifers in the hard rock terrain. Micaschists and shales having very thick weathered residuum also sometimes form good shallow aquifers to be tapped through dug wells.

In the study area, ground water occurs under semi-confined and confined aquifer conditions. The quality of ground water at project site is saline.

The depth of water table in the study area range varies from 4-5 m below ground level during pre- monsoon period and less than 2-4 m during post-monsoon period.

3.7.2 Selection of Sampling Locations The assessment of present status of water quality within the study area was conducted by collecting water from ground water sources and surface water sources during Monitoring Period. The sampling locations were identified on the basis of their importance. One surface water samples and five ground water samples were collected during monitoring period.

3.9 Ecology and Biodiversity

3.9.1 Introduction

Oil terminal development activities can have a wide range of impacts on biodiversity, both positive and negative. The development is proposed for the construction for isolated storage of petroleum products (Grass-Root Petroleum Storage)& Distribution Terminal of Indian Oil Corporation (IOCL) at Asanur village in Tamil Nadu involves development of Storage tanks. Around 83,009 KL of Petroleum Products will be handled. About 700 M of pipeline shall be laid from existing pipeline station to the new terminal. Pipelines connecting tanks & other plant facilities shall be provided inside the proposed terminal. Study of biological environment is one of the important aspects in Environmental Impact Assessment in view of the need for conservation of environmental quality. Project being capital in nature shall contribute to the socio economic development, strengthening of the facilities in & around Villupuram. Natural flora and fauna are important features of the environment. They are organized into natural communities with mutual dependencies among their members and show various responses and sensitivities to physical abiotic influences. Integrating ecological thinking into the planning process is essential in the context of natural environment’s dramatic deterioration which has a direct consequence on socioeconomic development.

Ecology is the scientific study of the processes influencing the distribution and abundance of organisms and interaction among organisms. With changes in environmental conditions, structure, density and composition of plants, animals also undergo changes.

3.9.2 Objectives of Ecological Monitoring

a) To evaluate the prevailing ecological status of the habitats adjacent to the project site. b) To assess the impact of proposed construction for isolated storage of petroleum products on ecology, flora and fauna. c) To recommend suitable environment management plan to minimize any adverse impact on adjacent area due to the proposed developments. d) To list the plants and animals present in the study area as per the classifications of MOEF

3.9.3 Methodology

The study of flora involved intensive sample survey of vegetation in the project site and other locations applying standard methods. The vegetation present within a defined area is termed as a plant community. This is determined by the nature of the dominant species it contains. By the term dominant species or dominance it is understood that species of plants having same life and growth, forms predominating in an area. Abundance, relative abundance, density and relative density of each species diversity and evenness for each of the Zones were calculated using the numerical data (Ludwig and Reynolds 1988, Lande 1996, Smith and Wilson 1996). The biological environment within the identified area of 10 Km radius has been studied with respect to terrestrial and aquatic habitats. Since animals, unlike plants, are capable of movement from one place to another, the methodology applicable for their study is entirely different. The on- site observations were further supplemented by the information collected from secondary sources and other agencies. Both direct and indirect observation methods were used to survey the fauna. Visual encounter (search) method was employed to record vertebrate species. Additionally survey of relevant literature was also done to consolidate the list of vertebrate fauna distributed inthe area (Smith 1933-43, Ali and Ripley 1983, Daniel 1983, Prater 1993, Murthy and Chandrasekhar 1988). Since birds may be considered as indicators for monitoring and understanding human impacts on ecological systems (Lawton 1996) attempt was made together quantitative data on the group by.

Study Area Area is not protected under international conventions, national or local legislation for their ecological, landscape, cultural or other related value.

Forest Types in Study Area As per Champion &Seth classification, the Tamil Nadu state has 39 forest types which belong to 9 forest type groups tropical wet evergreen, tropical semi evergreen, tropical moist deciduous, littoral &swamp, tropical dry deciduous, tropical thorn, tropical dry evergreen, subtropical broadleaved hill and montane wet forest. Villupuram Forest Division consists of 26 Reserved Forests areas out of which tribal are living in Pitchavaram and Killai Reserved Forest. The main activities of this Division are the Protection and Preservation of the existing Natural Reserved Forests and Wild animals such as Spotted Deer, Antelope, Sloth bear etc., and the development of the degraded forests. This Division is implementing various forests acts to protect the Reserved Forests and Reserved Land. The forests of this division are divided into three regions from the points of view of topography, soil conditions and flora. The coastal regions contain the Casuarina plantations, sand dunes, mangroves and scrub jungle. The whole of Pitchavaram, Pitchavaram extension and Killai Reserved Forests and the Porto Novo and Ariyakosti URL.

Forests. The inland plains region contains the eucalyptus and miscellaneous fuel plantations and the thorny scrub jungles consist of Alwarmalai, Varanjaram, Porasakurichi, Magarur, Kattumailur, Nangur, Krishnapuram, Thottapadi, Kottalamalai, Melpalangur, Mallapuram and Poosapadi Reserved Forests and Pandur, Sirupakkam, Kattayanallur, Kuttakudi. The coastal regions contains sandy areas with sand dunes, tidal swamps scrub jungles.

3.9.4 Ecological Settings of Study Area

Open Scrubs Open scrub is largest land use in study area. The thorny scrub forests found in this part of Tamil Nadu receive very less rainfall and made up of thinly spread thorny forests of Prosopis juliflora which is considered as invasive species. The southern tropical thorn scrub type forests consist of open, low vegetation that is characterized by thorny trees with short trunks and low, branching crowns. The trees in study area attained maximum heights of 4–7 m. Typical grasses of this region include Chrysopogon fulvus, Heteropogon contortus, Eremopogon foveolatus, Aristida setacea and Dactyloctenium species. The plant species that dominate the vegetation in these forests are Acacia sp., Balanites roxburghii, Cordia myxa, Capparis sp, Prosopis sp. Azadirachta indica, Cassia fistula, Diospyros chloroxylon, Carissa carandas and Phoenix sylvestris.

Rivers The study area comprises of Gadilam, Gamukha, Maninukta, Varaha rivers. The district also contains Kaliveli tank. The Sankaraparani River originates on the western slope of Gingee Hill in Villupuram District of the State of Tamil Nadu. It has two sources, one in the Pakkammalai hills and one in the mountains of Melmalayanur. They join near Thenpalai village to form the main river. Sankaraparani is also known as Varahanadi or Gingee River.Pennar, Gadilam, Gomuki, Malattar & Sankaraparani are the five rivers flowing in the District.Gadilam River flows through Thirukoilur Taluk. Malattar River joins Gadilam before flowing into the Bay of Bengal. Pennar River flows through Thirukoilur and Villupuram Taluks Sankaraparani rises in GingeeTaluk and flows through Villupuram Taluk. Gomukhi the main tributary of Manimuktha River joins into Vellar River in Cuddalore District.

General Characteristics of Flora The family Fabaceae ranks first in possessing the largest number of taxa (547), followed by Poaceae (485 taxa), Asteraceae (307 taxa), Rubiaceae (236 taxa) and Orchidaceae (218 taxa). Out of 1788 genera recorded, about 50% are unispecific. Common genus found is Crotalaria, Cyperus, Strobilanthes, Euphorbia, Acacia, Eucalyptus.

General Characteristics of Fauna There has been no conservation of Biological resources and no conscious effort by the district administration to conserve the rare and threatened species of flora and fauna in the district. Wildlife census in Villupuram district indicates that 1460 animals are protected in the forest areas. The capacity to measure the status and any changes therein of animal resources are an elementary requirement for the ecological assessment. Present assessment surrounding project site incorporates approaches of recording faunal evidences and collecting information regarding animal species from respective resources.

Avifauna Diverse groups of birds were observed in the study area. Most dominant groups were thrushes, flycatchers, tits, warblers, babblers, larks and lapwings. Avifauna observed in open scrubs was dominated by Ashy Prinia (Prinia socialis), Drongo, Green Bee-eater (Merops orientalis), Blue Cheeked Bee-eater (Merops persicus), Bushlark (Mirafra erythroptera), Rufous Tailed Lark, Paddy field Pipits (Anthus rufulus) and red wattled lapwing (Vanellus indicus) etc. Other common birds observed at various places were cattle egret (Bubulcus ibis), house sparrow (Passer domesticus), common myna (Acridotheres tristis), streaked weaver bird (Ploceus manyar) and bank myna (Acridotheres ginginianus). These birds were found in close association with man and cattle. It has been observed that the majority of birds recorded in study area are omnivorous in habit preferring insects, worms etc. as the principal food item. This could be attributed to absence or very less diversity of fruit bearing plants in study region.

Endangered species No critically endangered, vulnerable or rare species as specified in IUCN Redlist were observed in study area.

Mammals No mammalian fauna was observed in reserve forest during present survey. However, Villagers around forest confirmed the presence of Indian Fox (Vulpesbengalensis), Wild Hare (Lepusnigricollis) and Grey Mongoose (Herpestes edwardsii). However, following species declared as Schedule I, II and IV as per Wildlife Protection Act, 1972 were recorded.

Reptiles Thorny forests, open scrubs and agricultural lands provide unique habitats for reptiles. The study area sustains wide variety of reptiles such as Spectacled Cobra, Common Krait, Russell's Kukri, Common Indian Monitor lizard, Indian Chameleon, Oriental Garden Lizard, Russell's Viper and various species of skinks and geckos.

Benthic and Fish Ecology in Rivers No benthic and aquatic fauna was observed in Vellary stream.

Diversity Indices Following indices were applied to flora in study area for estimation of ecological status of this area 1. Shannon’s index 2. Margalef’s index 3. Simpson’s index

Shannon’ Index

Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 102 | P a g e

EIA report for the proposed Petroleum Storage Terminal of storage capacity 80870 m3 of IOCL at Sy No 365/4 (pt) at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State

Typically the value of the index ranges from 1.5 (low species richness and evenness) to 3.5 (high species evenness and richness), though values beyond these limits may be encountered. Because the Shannon Index gives a measure of both species numbers and the evenness of their abundance, the resulting figure does not give an absolute description of a sites biodiversity. It is particularly useful when comparing similar ecosystems or habitats, as it can highlight one example being richer or more even than another. There is always the need to inspect the data or use another index to unpack the true reasons for the difference.

Where: where S is the total number of species and pi is the frequency of the ith species. The value Shannon’s index of flora in zone I (2.71) and zone II (2.75) was observed to be almost similar, indicating no difference in floral communities in these two zones. Whereas, Shannon’s index of flora in zone III was observed to be 3.82 indicating very rich diversity in this zone (Table 5). This could be attributed to diverse flora in AzhwarMalai Reserve Forest.

Margalef’s Index It is calculated from the total number of species presentand the abundance or total number of individuals. Margalef Index (D) = S – 1/ log e N Where: S – total number of species, N – total number of individuals The higher the index the greater is the diversity. The value of Margalef’s index for flora was observed to be 6.93, 6.51 and 8.13 in zone I, II and III, respectively.

Simpson’s Index Simpson's Index measures the probability that two individuals randomly selected from a sample will belong to the same species (or some category other than species).

Simpson's Indexλ = ∑ n(n-1)/N(N-1) Where: n – total individuals of each species N – Total individuals of all species With this index, 0 represents infinite diversity and 1, no diversity. That is, the bigger the value of D, the lower the diversity. This is neither intuitive nor logical, so to get over this problem, D is often subtracted from 1 to give: Simpson's Index of Diversity 1 - λ The value of this index also ranges between 0 and 1, but now, the greater the value, the greater the sample diversity. This makes more sense. In this case, the index represents the probability that two individuals randomly selected from a sample will belong to different species. The value of Simpson index for flora was observed to be 0.86, 0.77 and 0.97 in zone I, II and III, respectively.

3.9.5 Ecologically Sensitive Sites

Majority of study area is open scrubs and agricultural area. Open scrub sustained very unique ecology. However, no rare or endangered plant species was observed in scrubs. Similarly no breeding grounds and migration routes of birds or animals were observed. Sites identified as ecologically sensitive are mostly confined to hills. Maximum diversity of flora and avifauna was observed in reserve forests. Following sites are recognized as ecologically sensitive in study area.  AlwarMalai Reserve Forest : 6.7 km from Asanur  Koothakudi reserve Forest – 4.5 Km  Idaikkal Reserve Forest – 6.9 Km  Manimukta River – 2.40 Km  Gomukha River – 3.6 Km  Memattur Main Canal – 5.5 Km

Wildlife Management Plan Wildlife management is considered as an essential factor as it refers to diversity at all levels like genetic, species and community. The implementation of biodiversity conservation strategy is very judicious task, particularly in arid climate as that of study area. The formulation of a biodiversity management and wildlife conservation plan for a developmental Project is one of the steps towards the environment conservation. Human activities like industrialization, agricultural expansion, road construction, and other developmental activities are supposed to be major threats to biodiversity and wildlife, therefore, the most effective and efficient mechanisms for conserving biodiversity is to prevent further destruction of degradation of habitats. Four strategies required for the biodiversity management are in Situ strategy, ex Situ Strategy, reduction of anthropogenic pressure and rehabilitation of endangered species. These strategies will be followed for the proposed plan in this project.

Objectives of Wildlife Management Plan 1. Special efforts for conservation of critical/important plant/animal species, in study area 2. Maintain a sustainable approach between project activities, culture of local villagers and biodiversity conservation 3. Establish inventory for the scheduled species 4. Maintain data on traditional knowledge on medicines from local villagers

5. Prepare Forest Protection/Enhancement Plan In-situ Strategies These strategies are elaborated in detail in biodiversity enhancement plan Ex-situ Strategies The measures like establishment of task force, preparation of people’s biodiversity register, and conservation of scheduled species through ex Situ conservation, awareness programs, and removal of invasive species would also be applicable in this wildlife management plan. In addition, some of the conservation measures are described below.

Incentive for the Surrender of Air Guns Local villagers in study area confirmed the presence of Indian Fox, Grey Mongoose and Wild Hare in AzhwarMalai Reserve Forest. Illegal hunting of Wild Hare for its flesh and fur was observed to be common. However, villagers confirmed that Fox not being hunted as its sighting is very rare. Grey Mongoose is also considered as savior from venomous snakes; hence no threats to Mongoose are envisaged. Hunters with air guns are present in the surrounding of the Project areas. Enforcement of wildlife protection rules is not only the solution to protect the forest resources in study area. However, hunting may be discouraged through providing the attractive incentives for voluntary surrender of air guns. Simultaneously awareness program in the surrounding area would encourage the surrender of air guns. This plan may be strengthen by involving the locals in the Project works. Scheduled avifauna in the study area such as Indian Peafowl and Crested Serpent Eagle are being worshiped religiously. Peafowl is considered as carrier of Lord Karthik while Eagle is considered as carrier of Lord Vishnu. Villagers committed that they consider these birds as very sacred and hunting them is considered as sin. Hence, no threat to scheduled avifauna of study is envisaged. However, conservation of habitats of these birds is very much necessary. Habitats can be conserved through biodiversity enhancement and germ plasm conservation.

Germ Plasm Bank Seed center may be one of the important measures for the conservation of habitats. Objective of germ plasm bank is to preserve the genetic material of species and replenishes the seeds samples when their germination falls below the acceptable level. The seed center is the center of production of seeds of good genetic and physiological quality. Forest officials shall be consulted to further development of the center.

Rehabilitation Strategies Following Wildlife Rehabilitation Plan is proposed for the scheduled fauna. Improvement of vigilance can be achieved through construction of check posts and watch towers. This will reduce illegal hunting. Local villagers shall be engaged for this task. In order to strengthen the working capacity the volunteers of the wildlife management, they must be provided with necessary

Under the reward for informers program it is proposed to engage the villagers who are well acquainted with the area and are resourceful in gathering information for hunting. These people could be hired on a contractual basis.

Veterinary facilities and rescue camps for of wild animals shall be developed. For this purpose it is required to maintain a stock of medicines in addition to setting up of a mobile-rescue-cum- publicity-van. Provision of fire lines within critical areas will protect the forest from accidental fires.

Biodiversity Management Committee (BMC) The monitoring and evaluation of Biodiversity Management and Wildlife Conservation Plan will be carried out by a Biodiversity Management Committee (BMC). The committee will follow the guidelines of National Biodiversity Authority, State Forest Department to implement, monitor and evaluate the Biodiversity Management Plan of the proposed Project. The activities of BMC shall be consulted to the Chief Wildlife Warden/Principal Chief Conservator of Forests.

Occupational structure The occupational structure of the population in the study area has been studied. Total workers are classified on the basis of Industrial category of workers into the following four categories:

1. Cultivators 2. Agricultural Labourers 3. Household Industry Workers 4. Other Workers

Of the total workers category, cultivators (30.06 percent) and agricultural labour (52.86 percent) together constitute 82.92 percent of the total workers. It reflects that agricultural sector has absorbed maximum workforce in the study area. Only 2.19 percent of workers in the study area are engaged in the household industry.

Table 3.25: Distribution of Total (main + marginal) workers by category Total Total Workers Workers Cultivators Agricultural Household Others Labourers Industry Study Area 41,376 12,437 21,872 905 6,162 Villupuram 1,703,249 369,646 832,213 38,237 463,153 Cuddalore 11,69,880 1,65,170 5,39,412 32,027 4,33,271

In the study area, about 14.89 percent workers are engaged as ‘other worker’ category. The type of workers that come under this category of 'Other Worker' include all government servants, municipal employees, teachers, factory workers, plantation workers, those engaged in trade, commerce, business, transport banking, mining, construction, political or social work, priests, entertainment artists, etc. In effect, all those workers other than cultivators or agricultural labourers or household industry workers are 'Other Workers'. Thus it reflects that the opportunities for other workers category are very less in the study area as it is rural in nature.

During the proposed project an addition of ~ 300 trips per day (i.e. 150 trucks per day to and fro) of tank trucks is envisaged. To understand that impact due this addition the following modified scenarios on the access roads is discussed. The Node I is shown in the figure.

3.11.2 Modified Traffic Scenario & Level of Service

150 additional trucks i.e.300 trips assume to enter and exit during peak hrs for the proposed project (worst case scenario). Node I: ~150 trucks of 300 additional volume in PCU will be 3.7x300/9 = 124 per hour during peak hours.

Traffic Flow at Node I Total volume during peak hours in PCUs after completion of the project (V) = 1195+124 = 1319 Capacity of Road as per IRC (C) = 2400 PCU’s/hr Modified Existing Volume/Capacity ratio will be (V/C) = 1319/2400 = 0.55. The level of service of the road will be “C” after the proposed project that is “GOOD”.

The above results indicated that the post project scenarios will contribute to addition in existing traffic, the level of service will continue to be GOOD. Traffic will continue to run smoothly without congestion and no widening of road is anticipated.

CHAPTER 4. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES 4.1 Introduction Identification of impacts and mitigation measures of the same in Environmental Impact Assessment study helps in quantification and evaluation of impacts. During baseline study several impacts can be identified but it is necessary to identify the critical impacts both positive and negative on various components of the environment that are likely due to installation of proposed storage tanks. The environmental impacts can be categorized as either primary or secondary. Primary impacts are the ones that are caused directly due to the project activity on environmental attributes, whereas secondary impacts are indirectly induced.

The construction and operational phase of the project activity comprises various activities, each of which may have either positive or negative impact on some or other environmental attributes. The proposed project activities would impart impact on the environment in two distinct phases:

 During construction phase - Temporary or short term impact  During operation phase - May have long term impact

4.2 Impact Assessment

4.2.1 During Construction Phase Land/Soil Environment  During site preparation the topsoil will be removed from the project site and the approach road, which contains most of the nutrients and organisms that give soil productivity. This will in turn result in minor changes of topsoil structure.  Improper disposal of the excavated earth during installation of storage tanks may cause irreversible negative impacts on land environment  Storage of construction material/chemicals if not done at designated place can cause nuisance and hazards  Accidental spillage of Hazardous chemicals/oil may lead to soil contamination  Improper segregation and disposal of solid waste generated during construction phase by workers dwelling on site

Air Environment  The emission anticipated during construction period will include fugitive dust due to excavation of soil, leveling of soil, use of DG sets, movement of heavy construction equipment’s/vehicles, site clearing and other activities  This type of fugitive dust is expected to result in change in the baseline air quality specifically during the construction phase

EIA report for the proposed Petroleum Storage Terminal of storage capacity 80870 m3 of IOCL at Sy No 365/4 (pt) at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State

 Open burning of solid wastes can cause air pollution Noise Environment The proposed project will lead to emission of noise that may have significant impact on the surrounding communities in terms of increase in noise levels and associated disturbances. Following activities would result in increase in noise level;  Noise generated from operation of pumps and blower  Noise generated from vehicular movement  Noise generated from DG Set  Nuisance to nearby areas due to noise polluting work at night

Identified Impacts on Water Environment  Increased water demand during construction phase for site preparation, dust spraying, construction activities, curing, domestic and other water requirements for labour and staff onsite  Increase in site runoff and sedimentation  Water logging may create unsanitary conditions and mosquito breeding at site

 Domestic sewage will be the only source of water pollution.

 Un-captured run off from the site.

Ecological Environment  Construction may cause minor disturbance to nearby water birds habitat due to noise and vibration.

Socio-Economic Environment  The proposed project does not involve any displacement of inhabitants for the construction of terminal.  Construction phase could lead to creation of employment and procurement opportunities.  A multiplier effect will be felt on the creation of indirect employment through the local community establishing small shops like tea stalls, supply of intermediate raw materials, repair outlets, hardware stores etc.  Self- employment options for individuals possessing vocational or technical training skills like electricians, welders, fitters etc, which are likely to be sourced locally;  There would be influx of workers during construction phase which could lead to pressure on key local infrastructure such as water, healthcare, electricity.  The construction activity could lead to increased nuisance level from air emissions and noise due to transportation of material and equipment as well as labourers.

EIA report for the proposed Petroleum Storage Terminal of storage capacity 80870 m3 of IOCL at Sy No 365/4 (pt) at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State

 The construction activity could also lead to water logging in mud pockets leading to breeding of mosquito and related health impacts.

4.2.2 During Operation Phase Land/Soil Environment  Soil quality may be affected by accidental leakage and spillage of hazardous chemicals/oils  Improper segregation and disposal of solid waste generated during operation of the proposed project

Air Environment  No emission is envisaged during the storage and handling of fuel in storage tank.  No fugitive emission during loading and unloading of oil in and from storage tanks is envisaged.  Impacts on ambient air during operation phase would be due to emissions from operation of DG sets only during power outages.  Further, the air environment may have a little negative impact due to increase in storage capacity which will increase the truck movement for receipt and dispatch of oil.

Noise Environment  Impact of noise due to vehicular traffic  Noise generated due to DG sets

Water Environment  Stress on existing water supply  Generation of waste water  Increased run off from site.

6.3 EMP during Construction Phase

Environmental pollution during construction stage will be limited and for a temporary period during the construction activity. Construction should be planned in such a way that excavated material should be disposed safely. The manpower required for these activities should preferably be employed from nearby villages so that avenues of employment will be open to local people.

Directly or indirectly all the environmental components get affected due to the construction activity. The following environmental protection and enhancement measures are suggested for implementation by the contractor or the authority during the construction as applicable.

6.3.1 Air Environment

During the construction phase, gaseous emissions are expected from the heavy machineries deployed for construction. All other emission sources are intermittent. Though the gaseous emissions are not expected to contribute significantly to the ambient air quality, some generic measures to reduce fugitive and gaseous pollutants emissions during construction phase from point area and line sources shall include the following:  All equipment used during construction should have valid PUC certificate.  The storage and handling of soil, sub-soils, top-soils and materials will be carefully managed to minimize the risk of windblown material and dust  To avoid generation of air borne dust, water sprinkling should do.  There will be no on-site burning of any waste arising from any construction activities  All vehicles delivering construction materials or removing soil will be covered to prevent escape of dust  Engines and exhaust systems of all vehicle and equipment will be maintained so that exhaust emissions do not exceed statutory limits and that all vehicles and equipment are maintained in accordance with manufactures’ manuals. Periodic monitoring of this shall be undertaken to ensure compliance  Exhausts of other equipment used for construction (e.g. generators) will be positioned at a sufficient height to ensure dispersal of exhaust emissions and meet the standards set by CPCB.

6.3.2 Noise Environment

The following environmental management measures are recommended to mitigate adverse impacts on noise environment during construction phase:  Earth movers and construction machinery with low noise levels should be used  Periodic maintenance of construction machinery and transportation vehicles should be undertaken  Onsite workers should be provided with noise protection devices such as ear plugs/ muffs wherever necessary  Periodic monitoring for the noise levels within the project site and along the outside project boundary shall be undertaken to ensure compliance per CPCB set standards

6.3.3 Water Environment

Drinking water requirements during the construction phase by the contractors should be met from proposed bore wells on site. Construction labourers should be provided with adequate quantity of drinking water of potable quality.

Sufficient and appropriate sanitary facilities should be provided in order to maintain hygienic conditions in the camps of construction labourers. The wastes, such as, sanitary wastes should be treated in septic tanks followed by soak pits of appropriate size and technology.

The solid waste generated should be collected and disposed in an appropriate manner either at a landfill site or used as compost for agricultural uses. Area for maintenance of vehicles should be so located that contamination of groundwater by accidental spillage of oil can be prevented.

6.3.4 Land Environment

 On completion of construction works all temporary structures, surplus materials and wastes should be completely removed. Dumping of construction waste on agricultural land should be prohibited and stockpiles should be provided with gentle slopes.  The solid wastes such as paints, lubricants, oil, diesel containers or any other non-biodegradable wastes that have leachable constituents should be disposed to authorized recyclers.  A waste management plan should be prepared or integrated with existing plan before the commissioning, implemented and monitored. In areas, where soil quality for natural vegetation is of critical concern, loosening of soil in such areas will be done to mitigate soil compaction caused due to operation of heavy machinery.

6.3.5 Biological Environment

The region does not have dense vegetation and land use is dominated by agriculture activities. Following environmental management measures are recommended to mitigate adverse impacts on biological environment during construction phase:  Plantation should commence at the time site clearing is being undertaken  Number of trees replanted should be at least two times of trees removed  Native species must be planted

6.3.6 Socio-economic Environment

Given that the project and related developments like construction camps will not be dependent on local resources (power, water), during both construction and operations, the only likely impact on infrastructure would be on the roads, during the construction phase. Considering the high traffic emanating during construction phase an effective traffic management scheme should be developed to avoid congestion on the nearby and local roads. Local persons will get employment during Construction phase.

Suggestions Regarding the Plantation-process Pits measuring approximately 2’x2’x2’ may be dug where the soil is reasonably deep, and, pits measuring approximately 3’x3’x3’ where the soil is shallow or gravelly. Expose the pits to direct sunlight for about 15 days. If the soil at the site is reasonably good, pits may be filled with 80% site-soil + 20% composted cow- dung. About 200 gm Neem-cake and leaf-litter, grass or agricultural residue may be added. If the soil at the site is poor, pits may be filled with 35% site-soil + 35% fertile soil (from an external source) + 30% composted cow-dung. Neem-cake and other organic matter may be added as in the previous instance. Saplings should ideally be planted after the annual rains begin. The saplings would need to be watered once the rains cease. Construction of temporary shelters of locally available materials such as bamboo and grass around the growing saplings is recommended in the summer, to help the plants withstand the hot sun.

Nursery Development Nurseries would be developed with 6 to 8 seedlings per Sq. meter for potted plants. On an average range to 1.5 acres of land is required for nursery development. Nursery saplings would be developed for species such as Annona squamosa, Ficus benghalensis, Ficus religiosa, Albizzia lebbek, Azadirachta indica and Cocos nucifera. Methods like seed sowing and grafting shall be adopted.

Vermiculture Development and Usage Vermicompost is natural organic manure and its chemical composition is much more superior to compost made either in conventional composting pits or by bacterial decomposition. Vermicompost consists of humus, which is the basic building block of fertile soil. It contains all essential macro and micronutrients for plants in readily available form due to which plants are able to easily absorb them. Vermicompost is prepared with the aid of earthworms. Vermicompost pits shall be developed and biodegradable waste from NTPL premises shall be utilized for manure production.

General Guidelines Regarding the Plantation-plan The original topography and vegetation of the site must be retained, that newly-planted saplings may get the benefit of their natural micro-climate and may survive with relatively less inputs. Soil from the site should be used for the plantation, as far as possible, and supplemented with external nutrients only where necessary. Chemical fertilizers or pesticides must be avoided, as they reduce soil-quality and integrity, as also, the food/medicinal value of plants. Locally available leaf-litter, grass-cuttings, agricultural residue, compost or other organic material may be used as supplementary plant-nutrients. Ground-vegetation should be allowed to shed seeds before cutting or mowing it for mulch. This would leave behind a seed-bank to flourish in the next growing-season, providing a natural source of mulch for the following year.

EIA report for the proposed Petroleum Storage Terminal of storage capacity 80870 m3 of IOCL at Sy No 365/4 (pt) at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State

Burning of land must be avoided, as it reduces soil-quality, and harms the ground-vegetation, amphibians, reptiles and ground-nesting birds. Dumping of waste on the soil must be avoided. Non-biodegradable waste must be carefully collected and safely disposed. Biodegradable waste should be collected and processed, that it may be used to enrich the site-soil.Water-saving practices, such as drip-irrigation and mulching, are recommended. Prediction of Enhancement of Biodiversity On successful implementation of EBMP, diversity of region is expected to be increased. Plantation is proposed over 5 ha along the plant periphery. The proposed density of plant will be 4 no/100m2. Planting trees in denser manner will lead to survival competition between individuals and may not serve the purpose of greenbelt development. Hence total number of plants proposed over 5 ha will be 2,000. Overall 13 native tree species have been suggested for plantation. The present scenario of zone I and zone II is summarized in table below.

Table 6.1: Scenario of zone I and zone II Zone I Zone II Margalef Index 6.93 6.51 Shannon Index 2.75 2.71 Simpson Index 0.86 0.77 Evenness 0.66 0.66

The calculation of estimated diversity indices could be drawn as follows. The diversity indices are calculated on per hectare basis. Density of plantation will be 4 plants per 100m2, hence overall density will be 400 plants per hectare. To avoid monoculture formation, following plantation layout is proposed. Diversity indices can be derived from number of trees proposed to be planted.

The given layout represents plantation scheme of one hectare. Each block represents 100m2 area. As described earlier 4 plants are recommended in 100 m2 area. Hence, combinations of species to be planted in each block are given in this table. Based on this layout proposed diversity of greenbelt in future can be calculated. According to suggested plan species composition of each hectare will be as follows. Table 6.2: Suggested Trees & Shrubs Trees Shrubs Acacia nilotica Acacia catechu Alstonia scholaris Acacia pennata Anona squamosa Linn. Calotropis gigantean Azadirachta indica A. Juss. Calotropis procera Barringtonia racemosa Citrus limon Bauhinia variegata Clerodendrum inerme Buchanania lanzan Spreng Duranta repens Caesalpinia pulcherrima Murraya paniculata Cordia dichotoma Nerium indicum Callistemon citrinus Ricinus communis Casuarina equisetifolia Tabernaemontona divaricata Derris indica Thuja occidentalis Drypetes roxburghii Ficus religiosa Mimusopes hexandra Pithecellobtum ducle Peltophorum pterocarpum Zizyphus xylopyra

Prediction of enhancement of bio-diversity after plantation of these plants is explained in following section. Margalef Index of the region will increase to 8.3 in both zones. Shannon Index of the region will increase to 3.82 in both zones. Simpson Index of the region will increase to 0.97 in both zones. Evenness of species will increase to 0.96. Comparative analysis of increase in various indices is given in following figures.

It is expected that IOCL shall incur approximate capital expenditure of about INR 71.47 Crores and an annual recurring expenditure of about INR 2.51 Crores, at current price on environmental management. 6.7 Environmental Monitoring Programme

Introduction Environmental Management is nothing but resource management and environmental planning is just the same as development planning. They are just the other side of the same coin. The resource management and development planning look at the issue from narrow micro-economical point of view while environmental management views the issue from the broader prospective of long term sustained development option, which ensures that the environment is not desecrated. For the effective and consistent functioning of the project, proper environmental monitoring programme should be carried at the Asanur terminal. The programme should include the following:  Environmental Monitoring  Personnel Training  Regular Environmental audits and Correction measures  Documentation–standards operation procedures Environmental Management Plan and other records

Environmental Monitoring Work of monitoring shall be carried out at the locations to assess the environmental health in the post period. A post study monitoring programme is important as it provides useful information on the following aspects.  It helps to verify the predictions on environmental impacts presented in this study.  It helps to indicate warnings of the development of any alarming environmental situations, and thus, provides opportunities for adopting appropriate control measures in advance.

7.2.2 Scope of the Study The scope of the QRA is given below:  Identification of Hazards and Major Loss of Containment (LOC) events.  Calculation of physical effects of accidental scenarios, which includes frequency analysis for incident scenarios leading to hazards to people and facilities (flammable gas, fire, and smoke, explosion overpressure and toxic gas hazards) and consequence analysis for the identified hazards covering impact on people and potential escalation.  Damage limits identification and quantification of the risks and contour mapping on the plant layout.  Risk contour mapping.  Evaluation of risks against risk acceptable limit  Risk reduction measures to prevent incident to control the accident  Hazard mitigation recommendations based on QRA

7.2.3 Quantitative Risk Analysis Methodology An Overview Risk Analysis is proven valuable as a management tool in assessing the overall safety performance of the Chemical Process Industry. Although management systems such as engineering codes, checklists, and reviews by experienced engineers have provided substantial safety assurances, major incidents involving numerous casualties, injuries and significant damage can occur - as illustrated by recent world-scale catastrophes. Risk Analysis techniques provide advanced quantitative means to supplement other hazard identification, analysis, assessment, control and management methods to identify the potential for such incidents and to evaluate control strategies. The underlying basis of Risk Analysis is simple in concept. It offers methods to answer the following four questions: 1. What can go wrong? 2. What are the causes? 3. What are the consequences? 4. How likely is it? This study tries to quantify the risks to rank them accordingly based on their severity and probability. The report should be used to understand the significance of existing control measures and to follow the measures continuously. Wherever possible the additional risk control measures should be adopted to bring down the risk levels. The methodology adopted for the QRA Study has been depicted in the Flow chart given below:

Risk Assessment Procedure

Figure 7.1: Methodology

Hazard identification and risk assessment involves a series of steps as follows: Step 1: Identification of the Hazard Based on consideration of factors such as the physical & chemical properties of the fluids being handled, the arrangement of equipment, operating & maintenance procedures and process conditions, external hazards such as third party interference, extreme environmental conditions, aircraft / helicopter crash should also be considered.

Step 2: Assessment of the Risk Arising from the hazards and consideration of its tolerability to personnel, the facility and the environment, this involves the identification of initiating events, possible accident sequences, and likelihood of occurrence and assessment of the consequences. The acceptability of the estimated risk must then be judged based upon criteria appropriate to the particular situation.

Step 3: Elimination or Reduction of the Risk Where this is deemed to be necessary, this involves identifying opportunities to reduce the likelihood and/or consequence of an accident.

Hazard Identification is a critical step in Risk Analysis. Many aids are available, including experience, engineering codes, checklists, detailed process knowledge, equipment failure experience, hazard index techniques, What-if Analysis, Hazard and Operability (HAZOP) Studies, Failure Mode and Effects Analysis (FMEA), and Preliminary Hazard Analysis (PHA). In this phase all potential incidents are identified and tabulated. Site visit and study of operations and documents like drawings, process write-up etc. are used for hazard identification.

Assessment of Risks The assessment of risks is based on the consequences and likelihood. Consequence Estimation is the methodology used to determine the potential for damage or injury from specific incidents. A single incident (e.g. rupture of a pressurized flammable liquid tank) can have many distinct incident outcomes (e.g. Unconfined Vapour Cloud Explosion (UVCE), flash fire.

Likelihood assessment is the methodology used to estimate the frequency or probability of occurrence of an incident. Estimates may be obtained from historical incident data on failure frequencies or from failure sequence models, such as fault trees and event trees. In this study the historical data developed by software models and those collected by CPR18E – Committee for Prevention of Disasters, Netherlands (Edition: PGS 3, 2005) are used.

Risk Assessment combines the consequences and likelihood of all incident outcomes from all selected incidents to provide a measure of risk. The risks of all selected incidents are individually estimated and summed to give an overall measure of risk. Risk-reduction measures include those to prevent incidents (i.e. reduce the likelihood of occurrence) to control incidents (i.e. limit the extent & duration of a hazardous event) and to mitigate the effects (i.e. reduce the consequences). Preventive measures, such as using inherently safer designs and ensuring asset integrity, should be used wherever practicable. In many cases, the measures to control and mitigate hazards and risks are simple and obvious and involve modifications to conform to standard practice. The general hierarchy of risk reducing measures is: . Prevention (by distance or design) . Detection (e.g. fire & gas, Leak detection) . Control (e.g. emergency shutdown & controlled depressurization) . Mitigation (e.g. firefighting and passive fire protection) . Emergency response (in case safety barriers fail)

7.2.4 Hazard Identification

Identification of Hazards and Release Scenarios A technique commonly used to generate an incident list is to consider potential leaks and major releases from fractures of all process pipelines and vessels. This compilation includes all pipe work and vessels in direct communication, as these may share a significant inventory that cannot be isolated in an emergency. The following data were collected to envisage scenarios:  Composition of materials stored in vessels / flowing through pipeline  Inventory of materials stored in vessels  Flow rate of materials passing through pipelines  Vessels / Pipeline conditions (phase, temperature, pressure)  Connecting piping and piping dimensions. Accidental release of flammable liquids / gases can result in severe consequences. Delayed ignition of flammable gases can result in blast overpressures covering large areas. This may lead to extensive loss of life and property. In contrast, fires have localized consequences. Fires can be put out or contained in most cases; there are few mitigating actions one can take once a flammable gas or a vapour cloud gets released. Major accident hazards arise, therefore, consequent upon the release of flammable gases. Factors For Identification Of Hazards In any installation, main hazard arises due to loss of containment during handling of flammable liquids / gases. To formulate a structured approach to identification of hazards, an understanding of contributory factors is essential. Blast over Pressures Blast Overpressures depend upon the reactivity class of material and the amount of gas between two explosive limits. For example MS once released and not ignited immediately is expected to give rise to a gas cloud. These gases in general have medium reactivity and in case of confinement of the gas cloud, on delayed ignition may result in an explosion and overpressures.

Operating Parameters Potential gas release for the same material depends significantly on the operating conditions. The gases are likely to operate at atmospheric temperature (and hence high pressures). This operating range is enough to release a large amount of gas in case of a leak / rupture, therefore the pipeline leaks and ruptures need to be considered in the risk analysis calculations.

Inventory Inventory Analysis is commonly used in understanding the relative hazards and short listing of release scenarios. Inventory plays an important role in regard to the potential hazard. Larger the inventory of a vessel or a system, larger is the quantity of potential release. A practice commonly used to generate an incident list is to consider potential leaks and major releases from fractures of pipelines and vessels/tanks containing sizable inventories.

Range of Incidents Both the complexity of study and the number of incident outcome cases are affected by the range of initiating events and incidents covered. This not only reflects the inclusion of accidents and / or non-

For instance studies may evaluate one or more of the following: . catastrophic failure of container . large hole (large continuous release) . smaller holes (continuous release) . leaks at fittings or valves (small continuous release) In general, quantitative studies do not include very small continuous releases or short duration small releases if past experience or preliminary consequence modeling shows that such releases do not contribute to the overall risk levels.

7.2.5 Consequence Analysis

General Consequence assessment is conducted to understand the impact of identified scenarios in terms of thermal radiation (Jet fire, Flash Fire, Pool Fire), Explosion (vapor cloud explosion) & toxic dispersion. A range of potential consequences are assessed for each of the release scenarios identified. This step identifies the fatality probability, based on hazard type and caused by each release case, to personnel at a range of distances. The consequence evaluation of accidental release will include the calculation of the following parameters as a minimum:  Source term (Vapor and/or Liquid and/or Two phase discharge rate; release duration, spreading and evaporation)  Fire characteristics (jet fire, pool fire, flash fires);  Dispersion characteristics (flammable clouds);  Explosion characteristics;  Hazardous distances (referred to radiation from fires, UFL, LFL and overpressure levels);

7.2.6 Consequence Analysis Modelling

Discharge Rate The initial rate of release through a leak depends mainly on the pressure inside the equipment, size of the hole and phases of the release (liquid, gas or two – phase). The release rate decreases with time as the equipment depressurizes. The reduction mainly on the inventory and the actions taken to isolate the leak and blow-down the equipment

Dispersion Release of gas into the open air form clouds whose dispersion is governed by the wind, by turbulence around the site, the density of gas and initial momentum of the release in case of flammable materials the sizes of these gas clouds above their lower flammability limit (LFL) are important in determining whether the release will ignite. In the study, the results of dispersion modeling for flammable materials are presented as LFL distance

Consequence Event In this section of the report we describe the probabilities associated with the sequence of occurrences which must take place for the incident scenarios to produce hazardous effects and the modeling of their effects. Considering the present case the outcomes expected are . Flash Fire (FF) . Jet fires . Pool fire . Vapour Cloud Explosion (VCE)

Flash Fire Hydrocarbon vapour released accidentally will spread out in the direction of wind. If it finds an ignition source before being dispersed below lower flammability limit (LFL), a flash fire is likely to occur and the flame will travel back to the source of leak. Any person caught in the fire is likely to suffer fatal burn injury. Therefore, in consequence analysis, the distance of LFL value is usually taken to indicate the area, which may be affected by the flash fire. Flash fire (LFL) events are considered to cause direct harm to the population present within the flammability range of the cloud. Fire escalation from flash fire such that process or storage equipment or building may be affected is considered unlikely.

Jet fires Jet fire occurs when a pressurized release (of a flammable fluid) is ignited by any source. They tend to be localized in effect and are mainly of concern in establishing the potential for domino effects and employee safety zones rather than for community risks. The jet fire model is based on the radiant fraction of total combustion energy, which is assumed to arise from a point slowly along the jet flame path. The jet dispersion model gives the jet flame length.

Pool fires A pool fire is a turbulent diffusion fire burning above a horizontal pool of vaporizing hydrocarbon fuel where the fuel has zero or low initial momentum. Fires in the open will be well ventilated (fuel controlled), but fires within enclosures may become under-ventilated (ventilation-controlled). Pool fires may be static (e.g. where the pool is contained) or 'running' fires.

Vapour Cloud Explosion (VCE) Vapour cloud explosion is the result of flammable materials in the atmosphere, a subsequent dispersion phase, and after some delay an ignition of the vapour cloud. Turbulence is the governing factor in blast generation, which could intensify combustion to the level that will result in an explosion. Obstacles in the path of vapour cloud or when the cloud finds a confined area, as under the bullets, often create turbulence. Insignificant level of confinement will result in a flash fire. The VCE will result in overpressures. It may be noted that VCEs have been responsible for very serious accidents involving severe property damage and loss of lives.

7.2.7 Damage Criteria The damage criteria give the relation between the extents of the physical effects (exposure) and the effect of consequences. For assessing the effects on human beings consequences are expressed in terms of injuries and the effects on equipment / property in terms of monetary loss. This is shown in table 8 The effect of consequences for release of toxic substances or fire can be categorized as . Damage caused by heat radiation on material and people; . Damage caused by explosion on structure and people; . Damage caused by toxic exposure. In Consequence Analysis studies, in principle three types of exposure to hazardous effects are distinguished: 1. Heat radiation due to fires. In this study, the concern is that of Jet fires and flash fires. 2. Explosions 3. Toxic effects, from toxic materials or toxic combustion products. The knowledge about these relations depends strongly on the nature of the exposure. Following are the criteria selected for damage estimation: Heat Radiation: The effect of fire on a human being is in the form of burns. There are three categories of burn such as first degree, second degree and third degree burns. The consequences caused by exposure to heat radiation are a function of: . The radiation energy onto the human body [kW/m2]; . The exposure duration [sec]; . The protection of the skin tissue (clothed or naked body). The limits for 1% of the exposed people to be killed due to heat radiation, and for second-degree burns are given in the table below:

Table 7.3: Effects Due To Incident Radiation Intensity

Incident Type Of Damage Radiation (kW/m2) Sufficient to cause pain within 20 sec. Blistering of skin 4.0 (first degree burns are likely) Minimum energy required for piloted ignition of wood, melting 12.5 plastic tubing’s etc. 37.5 Sufficient to cause damage to process equipment

The actual results would be less severe due to the various assumptions made in the models arising out of the flame geometry, emissivity, angle of incidence, view factor and others. The radiative output of the flame would be dependent upon the fire size, extent of mixing with air and the flame temperature. Some fraction of the radiation is absorbed by carbon dioxide and water vapour in the intervening atmosphere. Finally the incident flux at an observer location would depend upon the radiation view factor, which is a function of the distance from the flame surface, the observer’s orientation and the flame geometry. Assumptions made for the study (As per the guidelines of CPR 18E Purple Book) . The lethality of a jet fire is assumed to be 100% for the people who are caught in the flame. Outside the flame area, the lethality depends on the heat radiation distances. . For the flash fires lethality is taken as 100% for all the people caught outdoors and for 10% who are indoors within the flammable cloud. No fatality has been assumed outside the flash fire area.

Overpressure: Vapour cloud Explosion (VCE) The assessment aims is to determine the impact of overpressure in the event that a flammable gas cloud is ignited. A Vapour cloud Explosion (VCE) results when a flammable vapor is released, its mixture with air will form a flammable vapour cloud. If ignited, the flame speed may accelerate to high velocities and produce significant blast overexposure. The assessment aims is to determine the impact of overpressure in the event that a flammable gas cloud is ignited. The damage effects due to 0.01 bar, 0.1 bar & 0.3 bar are reported in terms of distance from the overpressure source. In case of vapour cloud explosion, two physical effects may occur: . A flash fire over the whole length of the explosive gas cloud; . A blast wave, with typical peak overpressures circular around ignition source. For the blast wave, the lethality criterion is based on: . A peak overpressure of 0.1bar will cause serious damage to 10% of the housing/structures. . Falling fragments will kill one of each eight persons in the destroyed buildings The following damage criteria may be distinguished with respect to the peak overpressures resulting from a blast wave:

0.30 bar Heavy Damage Major damage to plant equipment structure

0.10 bar Moderate Damage Repairable damage to plant equipment & structure

0.03 bar Significant Damage Shattering of glass

Assumptions for the study (As per the guidelines of CPR 18 E Purple Book) . Overpressure more than 0.3 bar corresponds approximately with 50% lethality. . An overpressure above 0.2 bar would result in 10% fatalities. . An overpressure less than 0.1bar would not cause any fatalities to the public. . 100% lethality is assumed for all people who are present within the cloud proper.

7.2.8 Risk Analysis

Risk in general is defined as a measure of potential economic loss or human injury in terms of the probability of the loss or injury occurring and magnitude of the loss or injury if it occurs. Risk thus comprises of two variables; magnitude of consequences and the probability of occurrence. The results of Risk Analysis are often reproduced as Individual and groups risks and are defined as below.

Individual Risk is the probability of death occurring as a result of accidents at a plant, installation or a transport route expressed as a function of the distance from such an activity. It is the frequency at which an individual or an individual within a group may be expected to sustain a given level of harm (typically death) from the realization of specific hazards. Such a risk actually exists only when a person is permanently at that spot (out of doors). The Individual results are based on the occupancy factor for different category of personnel’s at that particular location. Individual Risk = Location Specific Individual risk * Occupancy factor Whereas, Location Specific Individual Risk corresponds to the level of damage at a particular location or area The exposure of an individual is related to:  The likelihood of occurrence of an event involving a release and Ignition of hydrocarbon,  The vulnerability of the person to the event,  The proportion of time the person will be exposed to the event (which is termed ‘occupancy’ in the QRA terminology). The second definition of risk involves the concept of the summation of risk from events involving many fatalities within specific population groups. This definition is focused on the risk to society rather than to a specific individual and is termed 'Societal Risk'. In relation to the process operations we can identify specific groups of people who work on or live close to the installation; for example communities living or working close to the plant.

Probabilities Population Probabilities It is necessary to know the population exposure in order to estimate the consequences and the risk resulting from an incident. The exposed population is often defined using a population density. Population densities are an important part of a QRA for several reasons. The most notable is that the density is typically used to determine the number of people affected by a given incident with a specific hazard area. Sometimes, population data are available in sketchy forms. In the absence of specific population data default categories can be used. The population density can be averaged over the whole area that may be affected or the area can be subdivided into any number of segments with a separate population density for each individual segment.

Failure/Accident Probabilities Event tree analysis A release can result in several possible outcomes or scenarios (fire, explosions, unignited release etc.). This is because the actual outcome depends on other events that may or may not occur following the

EIA report for the proposed Petroleum Storage Terminal of storage capacity 80870 m3 of IOCL at Sy No 365/4 (pt) at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State initial release. Event tree analysis is used to identify potential outcomes of a release and to quantify the risk associated with each of these outcomes.

The above event tree is used for calculating the event frequencies and the probabilities are defined in below: 1. Immediate Ignition Probability Table 7.6: Immediate Ignition Probability Immediate Ignition Probability (for Delayed Ignition Release Rate Low / Medium Reactive Chemicals) Probability < 10 kg/sec 0.02 0.01 10 to 100 kg/sec 0.04 0.05 > 100 kg/sec 0.08 0.1 The above table from Bevi manual & CPR 18E is used for ignition probability. 2. Explosion Probability In the sequence of events, following the ignition of a free gas cloud, an incident occurs demonstrating characteristics of both a flash fire and an explosion. This is modeled as two separate events: as a pure flash fire and a pure explosion. The fraction that is modeled as an explosion, F explosion, is equal to 0.4. The individual risks are calculated based on base event frequency, ignition probability, population density in the area etc. The accident event frequency details for this study are taken from Purple Book (CPR 18E). Table 9 shows the total failure frequency of Pipeline and Storage tank scenarios. For calculating the frequency to be applied for modeling the following factors are taken into consideration. Fire suppression systems The fire protection systems & firefighting facilities which are used to restrict fire, the various factors affecting the fire protection systems as per “Thomas F Barry, Risk Informed Performance Based Fire Protection System – An Alternative to Prescriptive Codes” are:
