quality due to the proposed project are only
during the transportation of the petroleum
products in the tank trucks, which will be the
vehicular emissions (mostly dust) which can be
considered negligible considering that, the
project is proposed to be set up in an industrial
area, and regular water sprinkling will be done to
avoid any negative impact on the environment.

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.

Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 39 | P a g e
Noise Environment:
Noise can be defined as an unwanted sound. A total of 10 locations were identified for ambient noise
monitoring in the study area. The daytime varied from 48.2 dB (A) Leq to 52.7 dB (A) Leq and night
time noise varied of 39.5 dB (A) Leq to 42.8 dB (A) Leq. Both daytime noise and night time noise
was within the limit.
Water Environment:
In order to establish the baseline water quality, 5 ground water and 1 surface water samples were
collected and analyzed in the study area. The analysis result for ground water samples were within
drinking water limit as per IS 10500: 2012. Details of analysis result are given in the EIA report.
Soil Quality:
Soil samples were collected from 5 locations in the study area and analyzed for physico-chemical
characteristics. Soil quality was found to be normal. Details of analysis result are given in the EIA
report.
Land Use/Land Cover of the Study Area:
Land use pattern of the study area covering 10 km radius includes seven classes such as
Waterbody, Agricultural Land, Paddy Field, Vegetation, Open Scrub, Built-up Land and Open
Waste Land.
Biological Environment:
The ecological study of the area has been conducted within 10 km radius of the project site in order
to understand the existing status of flora and fauna to generate baseline information.
Flora : 63 species of Trees,
Fauna: 6 species of mammals, 8 species of Reptiles
Avifauna: 44 species were identified within the Study Area.
Socio-economic Environment:
Analysis of the demographical statistics, based on Primary Census Abstract, 2001 & field survey
reveals that the study area has a total population of 79,771 in the study area. Average scheduled
castes constitute about 44.43 % of the total population of villages in the study area. The study area
has negligible social tribe population. Average literacy rate of the study area in 2011 was 70.97%
to total population. Villages in the study area have fairly good infrastructure facilities.
4.0 Anticipated Environment Impacts and Environment Management Plan
The potential impacts of the Isolated Storage Terminal shall be limited to the project site. There
will be insignificant impact on either air or water quality as no manufacturing process is planned.
Impact on soil quality is induced / short term in nature and can be avoided by applying good
construction practices to reduce the impact, if any, on soils to a great extent. Adequate measures

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 2. PROJECT DESCRIPTION
2.1 Type of the Project
M/s IOCL proposes to set up a new petroleum storage terminal of storage capacity 80870 m3 with
pipeline from CTMPL to terminal. Proposal is classified under Schedule 6(b) & Category ‘B’
according to EIA Notification 2006 & subsequent amendments.
2.2 Need and Justification of the Project
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, Tamil Nadu. 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.
In view of the above requirements, setting up of a Petroleum storage terminal at Asanur,
Villupuram, Tamil Nadu is very much required.
The expected increase in demand of the proposed products moving ahead is as mentioned below
in Table 2.1.

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.
Figure 3.3: Drainage Map of the study area
The project site is located 3.4 km away from the Manimuktha river and does not fall in the flood
basin of the river. Branch Manager,SIDCO Cudallore, vide letter no. 695/B/2015 dated 09/04/2018
and letter no 695/B/2015 dated 02.05.2018 has confirmed that, there has been no incidences of
flood in the area since 2007 (since the SIDCO Industrial Estate has been formed).
Contour Pattern of the Study Area
Contouring is the standard method of representing relief on topographic maps. Contour lines are
lines joining points of equal elevation on the surface of the ground. For a given map the vertical
distance between adjacent contour lines or the contour interval is fixed i.e.25mFigure 3.4Contour

3.3.2 Hydrogeology & Geology
Geomorphology and Soil types
Geomorphology
The residual hills and denudational hills are common in Tirukoilur, Kallakurichi and Gingee
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 Vanur Taluk.
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,

Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 74 | P a g e
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 Cuddalore
district. 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.

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,

gaseous pollutants.
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.

at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 83 | P a g e
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:
Leq (hrly) = L50 + (L10 - L90)2 / 60
Where,

Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 84 | P a g e
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.

3.8 Soil
Soil is generally differentiated into two horizons of minerals and organic constituents of variable
depth, which differ from the parent material below in morphology, physical properties,
constituents, chemical properties, and composition and biological characteristics. The physico-
chemical characteristics of soil have been determined at 4 locations during the monitoring period
with respect to colour, texture, cation exchange capacity, pH, N, P, and K etc. The sampling
locations have been selected to represent the study area.
3.8.1 Selection of sampling Locations
The soil sampling locations were identified primarily based on the local distribution of vegetation
and the agricultural practices. The sampling locations were mainly selected from agricultural field
and project site. The sampling locations are given in Table 3.15 and presented in Figure 3.9.
Table 3.15: Soil Sampling Stations in the Study Area

S2 Koothakudi village 5.44 W
S3 Seevamangalam village 6.13 NW
S4 Edichchithur village 4.65 E
S5 Elangiyanur village 3.33 S
3.8.2 Methodology
The soil samples were collected during monitoring period. The samples collected from the all
locations are homogeneous representative of each location. At random 5 sub locations were
identified at each location and soil was dug from 30 cm below the surface. It was uniformly mixed
before homogenizing the soil samples. The samples were filled in polythene bags, labelled in the
field with number and site name and sent to laboratory for analysis.
3.8.3 Soil Results
The detailed soil results of all the monitoring locations are shown in Table 3.16.

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

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,

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.

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
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
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 103 | P a g e
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

equipment such as a camera, wireless, binoculars and other minor equipment (altimeter, search
lights, sleeping bags, health kits, etc.) that would increase their capability and efficiency.
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.

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

at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 121 | P a g e
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.

at SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 122 | P a g e
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.
Ecological Environment
Leakage of products during transportation or due to leakage of pipeline may cause damage
to small reptiles and terrestrial flora and fauna of the surrounding area
Socio-Economic Environment
Project and associated construction of terminal will eventually lead to permanent job
opportunities in the organized and unorganized sector. There is likely to be increased
demand for security, kitchen help, need for drivers etc.
Development of physical infrastructure due to construction of the Terminal which could
benefit the local population.

4.3 Impact Mitigation Measures
4.3.1 During Construction Phase
Land/Soil Environment
Top soil will be stored carefully and will be used again after construction/installation phase
is over so as to restore the fertility of project site.
Considering the criticality of the storage tanks and the other facilities, land development
by an average of 1.5 m has been proposed which will protect the critical equipment from
any surface runoff from nearby catchment areas.
Bituminous materials /any other chemicals shall not be allowed to leach into the soil
Methods to reuse earth material generated during excavation will be followed
Waste oil generated from D. G. sets will be handed over to authorized recyclers approved
by CPCB
Usage of appropriate monitoring and control facilities for construction equipments
deployed
All hazardous wastes shall be securely stored, under a shed for eventual transportation and
disposal to the authorized TSDF
The solid waste generation due to workers dwelling on the site will be segregated and will
be transported and disposed off to waste disposal facility
All the chemicals used during construction phase will be stored safely and shall have proper
bund wall for the maximum volume of chemicals stored
Air Environment
Checking of vehicles and construction machinery to ensure compliance to Indian Emission
Standards3
Transportation vehicles, DG sets and machineries to be properly and timely maintained
and serviced regularly to control the emission of air pollutants in order to maintain the
emissions of NOX and SOX within the limits established by CPCB
Minimize idling time for vehicles and adequate parking provision and proper traffic
arrangement for smooth traffic flow
Use of good quality fuel and lubricants will be promoted. Moreover, low sulphur content
diesel shall be used as fuel for DG sets to control emission of SO2
Water sprinkling shall be carried out to suppress fugitive dust during earthworks and along
unpaved sections of access roads
Appropriate spill control measures and labeling / handling procedures shall be maintained

Attenuation of pollution/ protection of receptor through strengthening of existing
greenbelt/ green cover
However, the construction activities will be for temporary period and hence, its impact on the
existing ambient air quality as well as vegetation will be reversible. Dust emissions are likely to
be confined within the limited area.
Noise Environment
No noise polluting work in night shifts
Acoustic enclosures for DG Sets per CPCB guidelines
Provision of ear plugs for labour in high noise area
Provision of barricades along the periphery of the site
All contractors and subcontractors involved in the construction phase should comply with

4.4 Impact Matrix
The matrix was designed for the assessment of impacts associated with almost any type of project.
Its method of a checklist that incorporates qualitative information on cause-and-effect relationships
but it is also useful for communicating results.
Matrix method incorporates a list of impacting activities and their likely environmental impacts,
presented in a matrix format. Combining these lists as horizontal and vertical axes in the matrix
allows the identification of cause effect relationships, if any, between specific activities and
impacts. The impact matrix for the actions identified in Table 4.1 along with various
environmental parameters. A rating scale has been devised to give severity of impacts in the
following manner.
A. Beneficial (positive) impact – Long term
B. Low beneficial impact – Short term
C. Strong adverse (negative) impact – Long term
D. Low adverse impact (localized in nature) – Short term

CHAPTER 5. PROJECT BENEFITS
5.1 Project Benefits
The Proposed project will have indirect positive impact on surrounding area which is as mentioned
below:
Terminal will be set up on barren land; hence no displacement of people is required.
Substantial Socio-economic benefits.
Good Techno-commercial viability.
Around the project site semi-skilled and unskilled workmen are expected to be available from local
population in these areas to meet the manpower requirement during construction and Operational
phase.
There will be employment opportunity for local people during construction and operation phase.
Infrastructural facilities will be improved due to the project.
Critical analyses of the existing socio-economic profile of the area indicate that the impact of the
Project is expected to be of varying nature. The following are the impacts predicted.
Secondary employment will be generated thereby benefiting locals.
Thus a significant benefit to the socio-economic environment is likely to be created due to the
project.
5.2 Improvements in the Physical Infrastructure
The project will improve supply position of the High Speed Diesel (HSD), Motor Spirit (MS), Bio-
Diesel and Ethanol in Tamil Nadu state which is vital for economic growth as well as improving the
quality of life. Delivery distance by tankers, which in turn will reduce trucks on the road the vehicular
load on the already strained public roads, thereby reducing the noise pollution as well as air pollution
at local levels and also reduced probability of accidents on the roads due to less movement of tank
trucks.
Establishment of large developmental projects improve the availability of the physical infrastructures
like approach roads, drainage, communication and transportation facilities etc.
5.3 Improvements in the Social Infrastructure
IOCL POL terminal shall take up some community welfare activities under Corporate Social
Responsibility and also improve the social infrastructures like education and health care system etc.
5.4 Employment Potential
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.

contractors during construction phase as well as during operation phase. The Project Proponents will
contribute reasonably as part of their Corporate Social Responsibility (CSR) in and will carry out
various activities in nearby villages.
Moreover, unit has planned to carry out various activities for the up-liftment of poor people, welfare
of women and labors, education of poor students as part of CSR in the nearby villages and therefore ,
during and after proposed project, unit will spent more than that required by statutory norms every
year towards CSR activities. The various CSR activities in accordance with the Corporate planned at
present by the unit is described below;
Plantation along the road side and development of garden/greenbelt on government barren
land/common plots
Education aids and scholarship to poor students
Organize medical camp and providing support for the development and maintenance of the health
facilities
Financial support and assistance for the development and maintenance of the infrastructure
facilities
Participate and contribute in local religious and social programs
Organize various types of training program for the community like training on scientific
agricultural practices, educational training, training for tailoring, embroidery, etc. which ultimately
helpful for income generation
Organize various types of awareness program for the community like awareness on the child labor,
educational promotion etc.
The activities listed above are not limited to and IOCL will plan and perform other activities according
to the need of local community in future. The utilization of this fund in various areas with time bound
action plan will be decided based on the requirement of the local community.

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

SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 146 | P a g e
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.

Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 147 | P a g e
6.3.7 Health and Safety
The movement of heavy equipment should be done with proper precaution to prevent any accidents
on the road. Occupational risk should be minimized at the project site through implementation of
a full proof safety system. Speed limit set for movement of vehicles with 20 km/hr on village roads
to reduce risks of accidents or injuries.
Safety training should be provided to all construction workers on operation of equipment. Security
should also be extended during non-working hours to ensure there is controlled access to the
machinery and equipment.
The contractors should also be vigilant to detect workers showing symptoms of communicable
diseases. All contract labors should be vaccinated. All illness and incidents shall be reported and
recorded.
6.4 EMP during Operation
In order to mitigate the impacts due to proposed project/ facility on various environmental components,
the following environmental management measures are recommended:
6.4.1 Air Environment
Ambient air quality with respect to SPM, RPM, SO2, NOx, H2S, CO and HC monitoring shall be
continued at appropriate locations in the impact zone
To minimize occupational exposure/hazards, the present practice of using personal protective
facilities like helmets, safety (gas) mask/safety dress, shoes etc. be ensured for all workers, engaged
in operation of process units within the facility complex
Stacks of adequate height (CPCB norms) for DG Sets to ensure adequate dispersal of pollutants
will be provided.
Waste oil will not be incinerated and will be sold to MoEF/TNPCB authorized waste oil recyclers
All access roads (internal as well as external) to be used by the project authorities will be paved
(either with Concrete, Paver Blocks or bitumen) to suppress the dust generation along the roads
6.4.2 Noise Environment
Similar measures as proposed in the construction phase for noise making machinery, to ensure
practicably low noise levels within the work environment.
The major areas of concern for noise generation will be adequately addressed by considering it
during procurement of the machinery from vendors, project implementation stage. Further
feedback from the monitored noise levels at sensitive locations will be taken to ensure that the
impact due to high noise levels is practically minimized
Monitor job and location specific noise levels for compliance with HSE regulations by verifying
acceptability of noise levels caused by the project activities and comparison with noise criteria
Conduct periodic audiometric tests for employees working close to high noise levels, such as
compressors, DG sets, etc
Provision of PPE’s will be done and their proper usage will be ensured for eardrum protection of
the workers as well as visitors

Sound proofing/ glass panelling should be provided at critical operating stations/ control rooms,
etc
Monitoring of ambient noise levels should also be carried out regularly both inside the facility area
as well as outside the peripheral greenbelt
6.4.3 Water Environment
Mechanized Oil Water Separator (OWS) System
A holding tank of 200m3 will be provided to receive following streams:
Storm water streams potentially contaminated by oil
Tank Cleaning
Waste Water generated periodically from fire drills and fire fighting in case of accident.
This tank will then be connected to OWS with a capacity of 100 m3/hr. The oil free water should then
be used for green belt development to the extent possible.
Additionally, for domestic sewage, 10 kLD Sewage Treatment Plant will be provided. The treated
sewage will be used for irrigating the green belt.
There will be no disposal of untreated water on land.
6.4.4 Land Environment
Every precaution should be taken to avoid spillage of oils and other petroleum products on soils to
protect groundwater and to avoid any danger to other soil microbial groups which are sensitive to
oil pollution
Oil is a potential hazardous substance present in wastes generated from facility. Special care has
to be taken in all oil removal operations. OWS Sludge will be sent to authorized HWTSDF.
Greenbelt in and around the facility may be strengthened/maintained
A record w.r.t quantity, quality and treatment/management of solid/hazardous waste shall be
maintained at environmental monitoring cell
Solid/ Hazardous Waste Management
Tank bottom sludge is generated while cleaning of oil storage tanks. The cleaning of oil storage
tanks is done once in five years as per practice of Oil Industry.
Total tank bottom sludge thus generated is kept in secured, covered impermeable sludge pit located
within POL terminal at a central place earmarked for the purpose prior to safe disposal through
MoEF&CC/ State PCB approved registered recycler.
Used oil, grease and empty drums shall be disposed of through registered vendors as per Handling
of Waste Material and Transboundary Rules, 2016 and subsequent amendment

6.4.5 Biological Environment
Development of green belt with carefully selected plant species is of prime importance due to their
capacity to reduce noise and air pollution impacts by attenuation/assimilation and for providing food
and habitat for local micro fauna.
6.4.6 Socio-economic Environment
In order to mitigate the impacts likely to arise out of the proposed project and also to maintain good
will of local people, it is necessary to take steps for improving the social environment. Necessary social
welfare measures by the industry shall be useful in gaining public confidence and meet local area
development requirement. The following measures are suggested:
IOCL shall continue to undertake social welfare programs for the betterment of the Quality of Life
of villages around in collaboration with the local bodies
Some basic amenities, viz. education, safe drinking water supply to the nearby villages may be
taken up
Regular medical checkup shall be continued on routine basis in the villages around the facility and
also by providing mobile hospital services
Formal and informal training to provide direct and indirect employment to the affected villagers
due to the project shall be taken up on priority
Focus shall be on literacy program in collaboration with local government and emphasis will be
placed on female literacy. Wherever feasible awareness on improved agricultural practices for
increased utilization of land around will be taken up in collaboration with local government &
panchayat
6.5 Action Plan for Greenbelt Development
6.5.1 Development of Green Belt
The greenbelt development plan aims at overall improvement in the environmental conditions of the
region. The plan is developed with following objectives.
Prevention of land degradation due to activities during construction phase
Enhancing the forest cover for increasing the biodiversity of the region
Providing aesthetic value to the project area
Enhancing the ecological equilibrium of the area
Combating soil erosion
A detailed survey was conducted with respect to existing forest types, vegetation diversity and density
etc. In the project area for development of greenbelt around project components. The greenbelt plan
has been formulated considering the parameters such as climate, soil types etc. Greenbelt around
project location will attenuate dust emission and noise during construction. Layout plan for green belt
development showing 33% of the total plot is shown in Figure 6.2.

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.

SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 152 | P a g e
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.

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.

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.

CHAPTER 7. ADDITIONAL STUDIES
7.1 Public Consultation
According to the provision of notification No.SO 1533 (E) Dated 14-09-2006 and the procedure
prescribed therein the TNPCB conducted the Public Consultation for the proposal of M/s Indian Oil
Corporation Limited for Greenfield Petroleum Storage & Distribution Terminal at Sy No. 354(4) (Pt),
Village: Asanur, Tehsil: Ulunderpet and District: Villupuram, Tamil Nadu. The Public Notice
informing the conducting of the Public Hearing meeting was published on 12.10.2017 in two
Newspapers, viz. “The New Indian Express”, English Daily and “Dinamani”, Tamil Daily. The public
hearing meeting for the above said project was conducted on 16.11.2017 and headed by the District
Revenue Officer, Villupuram District, within the premises of M/s. Indian Oil Corporation Limited,
(Southern Region Pipeline- Pumping Station), Plot No. 107, SIDCO Industrial Estate, Asanur (NH-
38, Near KM Stone 211), Asanur P.O., Ulundurpet Taluk, Villupuram District. Following concerns
were discussed at the Public Hearing and below are the responses to the concerns raised as mentioned
in Table 7.1.

raised
1 Valasai village is around three kilometers from
the proposed IOCL Terminal. This area is the
drain for around 15 lakes and the catchment area
for Valasai Eri is just started from 20 meters from
the proposed IOCL Terminal and having nearly
100 acres catchment area. The construction of
compound wall by IOCL will definitely bypass
the watercourse and the same will be flowing
towards the lake near Valasai where the Asanur
lake drain is also joining in that place. During
heavy rains, the water flows like a river and if the
same is bypassed by compound wall, the entire
water will enter into the lake near Valasai Village
which is around 15 meters down from this
meeting place, where around 4000 people will be
put to severe Hardships in case of any breach in
the lake.
M/s. IOCL authorities reported that
SIDCO had relocated/re-allotted the
land leaving the watercourse area to
ensure the free flow water in the rainy
season. They said that they met the
Superintending Engineer, SIDCO at
Chennai and they have discussed the
issue of drain and they assured that they
will provide a drainage system for free
flow of water to flow towards the lake
and they will take all precautionary
measures for the safety of the village.
2 They also insisted the employment opportunities
to the local people from the above proposed
project.
While responding to the above question
by IOCL, the official of IOCL said that
no direct employment will be offered
and the vacancies for the different post
will be filled either through Press

7.2 Quantitative Risk Assessment (QRA) Study
7.2.1 Introduction
M/s. IOCL intends to conduct Risk Analysis study for the POL Storage terminal proposed to be
constructed at Asanur, Villupuram District in Tamil Nadu to assess the risk associated with loss of
containment of the products proposed to be stored. This scope was awarded to Ultra-Tech
Environmental Consultancy and accordingly risk analysis and quantitative risk assessment study has
been carried out to provide a better understanding of the risk posed to the plant and surrounding
population. The consequences & Risk estimation modeling was conducted using PHASTRISK
(Version 6.7) software developed by DNV GL.

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.

SIDCO Industrial Estate, Asanur Village, Ulundurpet Tehsil, Villupuram District, Tamil Nadu State
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 163 | P a g e
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-

accident-initiated events, but also the size of those events. 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:

Incident
Radiation (kW/m2) Type Of Damage
4.0 Sufficient to cause pain within 20 sec. Blistering of skin
(first degree burns are likely)
12.5 Minimum energy required for piloted ignition of wood, melting
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:

Peak Overpressure Damage Type Description
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
Prepared by ULTRA-TECH Environmental Consultancy and Laboratory 192 | P a g e
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
Release Rate Immediate Ignition Probability (for
Low / Medium Reactive Chemicals)
Delayed Ignition
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:
