3. Description of The Environment

The baseline environmental study comprises of investigation of Air, Water, Soil and

Noise quality parameters and its results are discussed briefly.

3.1 Air and Meteorological Environment

13

To achieve this objective, five ambient air quality stations are proposed within a radius of

10 km from the project site. The frequencies were computed on 00-24hrs corresponding

to study period as shown in subsequent sections. The hourly meteorological data of wind

speed, wind direction, temperature and solar radiation were recorded at the project site.

Parameters such as heavy metals, Gaseous pollutants and particulate matters are

analyzed and monitoring results are within the prescribed limits.

3.2 Noise Environment

The prevailing ambient noise levels at study area were monitored at five locations within

10km radius. The field observations during the study period indicate that the ambient

noise levels in the study area were well within the prescribed standards at all the

different noise zones prescribed by CPCB.

3.3 Water Environment

To assess the quality of water around the project site three sampling locations of surface

water and three locations for ground water were selected within 10km Radius of the site

for Physiochemical parameters, heavy metals, and biological parameters.

3.4 Soil Environment

Soil characteristics such as color, porosity, soil texture, aluminium, chromium, copper,

sodium, chlorides etc. were analyzed at five sampling locations within 10km radius of the

site.

3.5 Ecology

There is no Wild life sanctuaries/ National / Reserved forest within 10 Km radius of the

site and there is no rare/ endangered species in the project study area.

3.6 Socio-Economic Environment

Proposed change of product mix is to be taken up in existing site with some

modifications and there will be no rehabilitation and resettlement.

4. Anticipated Environmental Impacts & Mitigation Measures

14

The methodology adopted for carrying out the Environmental Impact Assessment for the

proposed Project has been based on the Guidelines issued by Ministry of Environment &

Forests (MoEF). An effective environmental impact assessment calls for establishing

sufficient background data on various environmental components through

reconnaissance survey, sampling and available literature sources etc. The proposed

project will have impacts on the environment in two distinct phases. During the

construction phase which may be regarded as temporary or short-term; the other during

the operation stage, which will have long term effects.

A careful examination of each of these activities with respect to the environmental

components establishes a “Cause and Effect” relationship between the activity and

environmental parameters.

The potential Environmental Impacts on Air, water, Soil, Hydrology, Flora and Fauna are

all studied carefully and the necessary mitigation measures were all proposed.

5. Environmental Management Plan

The Environmental Management Plan during construction and operation phase is

discussed to ensure the environmental protection around the project area.

EMP has been prepared addressing the issues like:

Mitigatory measures for abatement of the undesirable impacts caused during the

construction and operation stage.

Details of management plans (Greenbelt development plan, Solid waste

management plan etc.).

Institutional set up identified & recommended for implementation of the EMP.

Post project environmental monitoring programme to be undertaken after

commissioning of the project.

Expenditures for environmental protection measures.

Moreover, the recommendations for Disaster Management Plan, Occupational Health

and Safety Plan, fire and explosion controls, greenbelt development and rain water

15

harvesting system and energy conservation schemes should be considered and

implemented in the project.

6. Risk Assessment

Predicting and evaluating risk to take appropriate preventive measures during the

operation phase.

• The methodology and approach for the studies are based on Indian Standards IS

15656:2006 HAZARD IDENTIFICATION & RISK ANALYSIS – CODE OF PRACTICE.

• Risk analysis tools used in the assessment include PHA – Process Hazard Analysis,

consequence and frequency analyses.

• The onsite storage units consist of underground & above ground tanks. The total

petroleum storage tankage capacity will be 1,17,035 KL.

• As the activities involve flammable materials and are classified as hazardous, risk analysis

studies were conducted to assess the degree of risk.

• The Study has assessed the site for potential to initiate and propagate an unintentional

event or sequence of events that can lead to an incident and / or an emergency situation

within the installation.

• The risk zones will be mainly within the plant site and will not have any effect on the

persons outside the plant.

• The maximum individual risk at manned location in the installation was assessed and

found to range between 10 -10/Yr to 10-11/Yr.

Also, additional safety measures are recommended for the same.

Emergency management plan, policies and principles for safety aspects of the employees

is given which are to be strictly followed by management and employees.

7. Conclusion:

Due to the proposed Oil storage Terminal the impact on environment will be minimum

and can be further reduced by implementing various mitigating measures and regular

monitoring programs.

16

The proposed Oil Storage Terminal will serve as a southern hub and have beneficial

impacts in terms of supply of petroleum products in the region with incidental benefits

like employment opportunities both in the construction stage and operation stage. Also

the modernized installation will facilitate greater level of operating safety.

BPCL has a successful track record of implementing various EMP’s & DMP’s in their

existing recently constructed installations.

Due to the proposed project the socio economic activities will be developed in and

around the project area.

As zero discharge Effluent Treatment Plant is envisaged and the impact on water

environment will be minimum. Various conservatory measures are proposed to be taken

for minimizing water consumption.

Tank bottom sludge Management and its action Plan

Proper disposal method such as Bio-remediation or disposal through authorised vendor

as per directives of TNPCB have been planned to carried out for disposal of solid waste

generated from the periodic cleaning of the tanks (once in 5 years) Hence the project is

recommended by the consultant.

2.16 Green Belt Development Plan

For maintaining the ecological balance, dust control and mitigate noise pollution, greenery is

proposed to be developed to the maximum extent as permitted by the lay out along the proposed

plant boundary and inside the plant. Green belt area will be developed in and around the project

area.

The green lawns and the water-bodies compliment the grace and symmetry of the buildings. The

nature of plantation comprises of trees, lawns, shrubs along the periphery of boundary wall , islands

and pathways.

Extensive plantation and landscaping is proposed to mitigate any impacts during this phase.

Development of a green belt in and around the building area is an effective way to check pollutants

and their dispersion into the surrounding areas. The degree of pollution attenuation by a greenbelt

depends on its height and width, foliage, surface area density, dry deposition velocity of the

pollutants and the average wind speed through the greenbelt.

The objectives of green belt management are:

To create a soothing environment for people to work

To mitigate vehicular emissions and noise pollution

36

To cultivate culture of greenery within and outside the project site.

To maintain landscaping by optimal use of resources

Garden waste is accumulated in a designated area and shall be disposed accordingly.

3 BASELINE ENVIRONMENTAL SCENARIO

3.1 BASELINE DATA

The baseline environmental status with respect to various environmental components like air,

noise, water, land, flora and fauna and socioeconomic, being integral part of an EIA, forms the basis

for predicting/assessing the environmental impacts of the proposed project. Field monitoring at

site was performed for a period of one season from March 2015 to May 2015, representing the

Pre-monsoon season. Various environmental components were monitored and samples were

analyzed.

The Baseline data for Air, Water and soil has been carried out. The monitoring locations are located

within 10 kilometer radius of the site.

3.2 Study Area

Figure 3-1 Proposed Site

Figure 3-2 Site photographs

3.3 LAND USE PLAN

Land use information of an area in the form of map and statistical data are very vital for spatial

analysis, planning, management and utilization of land for agriculture, forestry, urban and

38

industrial planning. The level of spatial classification is classed under 4 categories. They are Level 1

with 1:1 million scale, Level 2 with 1:250,000 scale, Level 3 with 1:50,000 scale and level with

1:25,000 or larger scale. The cost and availability of data and purpose for which the land use

classification is to be taken up is important for taking up the level of classification. In the present

study Level 3 classification is made which is fairly a good classification of urban and industrial

planning. However, level 4 classifications is the ultimate for all kind of planning and management.

Owing to the exorbitant cost and time of obtaining the Satellite Data from the concerned agencies,

the present land use classification has been restricted to level 3

The land use of the study area reflects the socio-economic conditions of the people in addition to

the natural environmental factors. The factors controlling the land use pattern of the area are land

forms, slope, shape of the land, soil, natural resources and natural and man made hazards. In the

hills of the study area there is no dense vegetation. Vegetation consists of thorny bushes and

shrubs. The uncultivable area includes barren and non-cultivable waste.

The crop land occupies 45.47% percentage of the study area followed by Forest Plantation (19.31

%). Agricultural fallow occupies 19.31 % followed by Wetlands of 9.82%.

3.5 BASELINE DATA

3.5.1 AIR ENVIRONMENT

Micro-meteorological factors have direct bearing on the dispersion and dilution of Pollutants/

contaminants discharged into the atmosphere with consequent impact on air environment. It

governs the concentration of pollutants and varies with time and location with respect to their

sources.

3.5.2 SAMPLING LOCATION AND RATIONALE

Micro-meteorological station was installed in the core zone area, with the objective of recording

wind direction and speed, temperature & humidity. The data thus collected from the station will be

representative of the prevailing micro - meteorological aspects of core and buffer zone.

41

Figure 3-4 10 km Radius map

3.5.3 Wind Speed / Direction

Hourly data on wind speed and direction has been analyzed for 16 wind directions.

3.5.4 Methods of Collection of Ambient Air Parameter

The Hi-Volume samplers were placed at height of 2.5 mts above the ground level, free from

obstructions. Samples were collected for various parameters as listed above, at 24 hourly intervals

twice in a week for four weeks, thus totaling to eight days /location in a study period of one month.

The collected samples are shifted to HECS laboratory through standard chain of custody norms and

practices and they are analyzed according to the Standards prescribed by Indian Standards (IS).

3.5.5 Data Inference

3.6 Micro metrology

The study of micro-meteorological conditions of a particular region is of utmost importance to

understand the variations in ambient air quality status. The prevailing micrometeorology at project

site plays a crucial role in transport and dispersion of air pollutants released from the plant. The

persistence of the predominant wind direction and wind speed at the project site will decide the

direction and extent of the air pollution impact zone. The principal variables which affect the air

pollution dispersion and resultant air quality status micrometeorology are horizontal transport and

dispersion (average wind speed and directions), convective transport and vertical mixing

(atmospheric stability) and also topography of the area towards local influences.

For determining the prevailing micro-meteorological conditions during the study period, an

automatic continuous digital weather station was installed at project site. The location is chosen

such that there is no obstruction to the flow of wind and sunlight. The hourly meteorological data

of wind speed, wind direction, temperature and solar radiation were recorded at the project site.

These frequencies were computed on 8 hourly as well as 24 hourly basis and the corresponding

results are used to draw wind rose for 00-08hrs, 08-16 hrs, 16-24 hrs and 00-24hrs corresponding

to study period as shown in subsequent sections. The terrain is flat and elevation varied from 3-6 m

above mean sea level when one travels from coast and landward. The wind rose for the months of

March and April 2015 shows the predominant winds . The wind directions during the study period

are SW-W-WSW and SE. Accordingly, the impact zone will be spread in NE-E-ENE and NW

directions. The average wind speed observed during the study period is 3 m/sec with the

considerable frequency of a wind range of calm to about 22 km/hour. Due to its proximity with the

Bay of Bengal, the ambient temperature at project site ranged between 25-40°C while the relative

humidity range from 49-79% at project site. The meteorological data collected during monitoring is

used for interpretation of baseline status and to simulate the meteorological conditions for

prediction of impacts in modeling studies.

3.7 Noise Environment

The study area consists of 10 km radius from the site which consists of urban, rural and industrial

area. The noise generated due to operation of individual process units at an industrial site cause

significant impacts on the surrounding environment including nearby residential areas. Such

operations fall in the category of continuous primary sources. There are also some secondary noise

sources associated with almost all types of large scale industrial projects, which are mainly vehicles

used for transportation of materials as well as employees and material handling equipment at the

project site. However, such sources could be categorized as intermittent noise sources.

The prevailing ambient noise level at a particular location is nothing but the resultant (total) of all

kinds of noise sources existing at various distances around that location. The ambient noise level at a

location varies continuously depending on the type of surrounding activities. The ambient noise level

generally does not reflect any seasonal variation, however, the wind direction, rain, snow, fog or any

other barrier as well as direction of source play significant role in regulating the noise propagation

and ultimately the intensity of impact.

The current status of noise environment around the existing industries is assessed through

identification of major noise sources, characterization of such noise sources, measurement of

prevailing ambient noise levels in the study area and measurement of noise levels due to vehicular

movements, according to existing land use pattern. The prevailing noise levels in the neighboring

industrial areas shall represent the baseline status for assessment of noise impacts from proposed

developments. The baseline study for noise environment has been carried out through

reconnaissance in the impact zone, identification of representative sampling locations and

monitoring of prevailing noise levels during study period.

3.7.1 Reconnaissance

Reconnaissance survey was conducted to locate the existing noise generating sources and identify

suitable locations to evaluate background noise levels. The project site is located in north coast of

Tamil Nadu in Thiruvallur district. The surrounding impact zone of 10 km radial distance consisting of

the rural, urban and industrial areas is marked. State highways number SH 56 passes by the site.

Category of Area Noise Levels dB (A) eq

Day time* Night time

Residential Area 55 45

Since the project site is located in industrial zone there are many small scale and few large scale

industries which contribute to baseline noise levels. The heavy vehicular traffic on state highway SH

56 contributes significantly to the noise levels in study area. The commercial activities in the

individual villages also influence the background noise levels. The noise levels in surrounding selected

villages, industrial complexes and junction of the state highways were monitored using a precision

noise level meter.

3.7.2 Community noise levels

The community noise is determined by recording the day-night noise level (Ldn). Ldn is defined as the

24 hours equivalent sound level derived with a penalty of 10 dB (A) is added to the measured

instantaneous noise level measured during night time. i.e. from 2200 hrs to 0600 hrs. This is because

the same level of noise during night time is more annoying than day time. Ldn for a given location is

calculated from hourly equivalent sound levels (Leq) using the following equation:



49

Ldn = 10 log [1/24{16(10(Ld/10)) + 8(10(Ln+10)/10))}]

Where, Ld – equivalent noise level during day time (0600 to 2200 hrs)

Ln – equivalent noise level during night time (2200 to 0600 hrs)

3.7.3 Baseline Noise status

The prevailing ambient noise levels along, the sites were monitored at 5 locations. During the study

period day time noise levels varied between50 to 72dB (A) across the sampling stations and night

time noise levels varied from40 to 60 dB (A) across the sampling stations. The details of the

monitoring stations are presented in Table 3-5. The field observations during the study period

indicate that the ambient noise levels in the study area were well within the prescribed standards at

all the different noise zones prescribed by CPCB.

Limits set by CPCB

Industrial Area: Day Time -75 dB (A); Night Time - 70 dB (A)

Commercial: Day Time -65 dB (A); Night Time - 55 dB (A)

Residential Area: Day Time -55 dB (A); Night Time -45 dB (A)

Silence Zone: Day Time -50 dB (A); Night Time - 40 dB (A)

3.8 WATER ENVIRONMENT

The study area has medium sized water courses namely Periyathoppu Lake, Korttalaiyar River etc.

The project site is located 3.16 Km west of the Bay of Bengal. The project site is located in Ennore,

Thiruvallur district.

3.8.1 Hydrogeology:

Hydrogeology in the district is underlain by both porous and fissured formations. . The important

aquifer systems in the district are constituted by

i) unconsolidated & semi-consolidated formations and

ii) weathered, fissured and fractured crystalline rocks.



50

The porous formations in the district include sandstones and clays of Jurassic age (Upper Gondwana),

marine sediments of Cretaceous age, Sandstones of Tertiary age and Recent alluvial formations. As

the Gondwana formations are well-compacted and poorly jointed, the movement of ground water in

these formations is mostly restricted to shallow levels. Ground water occurs under phreatic to semi-

confined conditions in the inter-granular pore spaces in sands and sandstones and the bedding

planes and thin fractures in shales. In the area underlain by Cretaceous sediments, ground water

development is rather poor due to the rugged nature of the terrain and the poor quality of the

formation water. Quaternary formations comprising mainly sands, clays and gravels are confined to

major drainage courses in the district. The maximum thickness of alluvium is 30.0 m. whereas the

average thickness is about 15.0 m. Ground water occurs under phreatic to semi-confined conditions

in these formations and is being developed by means of dug wells and filter points. Alluvium, which

forms a good aquifer system along the Araniyar and Korattalaiyar river bed which is one of the major

sources of water supply to urban areas of Chennai city and also to the industrial units. Ground water

generally occurs under phreatic conditions in the weathered mantle and under semi-confined

conditions in the fissured and fractured zones at deeper levels. The thickness of weathered zone in

the district is in the range of 2 to 12 m. The depth of the wells ranged from 8.00 to 15.00 m bgl. The

yield of large diameter wells tapping the weathered mantle of crystalline rocks ranges from 100 to

500 lpm and are able to sustain pumping for 2 to 6 hours per day. The yield of bore wells drilled

down to a depth of 50 to 60 m ranges from 20 to 400 lpm. The yield of successful bore wells drilled

down to a depth of 150 m bgl during the ground water exploration programme of Central Ground

Water Board ranged from 1.2 to 7.6 lpm.

3.8.2 Reconnaissance

Reconnaissance survey was undertaken to ascertain the location of water bodies viz streams, rivers,

lakes etc. The sampling stations were chosen based on the existing pollution sources near these

water bodies and threat of pollution in the future. The flow in the rivers passing through the study

region are seasonal, high flows occur during monsoon season and low flow occurs during summer

season.

The region receives rainfall predominantly during monsoon season with an average annual rainfall of

about 1211 mm per year. The South west monsoon season is from July – September and North east

monsoon is from October to December. Groundwater is the principal source for domestic and

drinking purposes in almost all villages near the study area. The water samples were collected and

analyzed by standard test methods which are given in table: The prevailing status of water quality

has been assessed during March - May. Three sampling stations for ground water and seven

sampling stations for surface water were selected for the study the details are given the findings of

the water quality monitoring study is summarized in Table 3-8.

3.10 ECOLOGY

3.11.1 Terrestrial Ecology

The study of terrestrial ecology within the study area of 10 km radius has been carried out

through field investigation and satellite imagery data as discussed earlier. The area can be

classified into the following ecological zone.

i. Scrub Eco-system (dry evergreen vegetation)

This type of ecosystem is dominated by Phoenix sylvestris species. Apart from typical scrub jungle

species, a few salt tolerant species were also recorded, probably because of the proximity to the

sea and the estuary.

ii. Tidal Eco-system

The plant growing in this area are salt tolerant as they are covered by the saline water during

high tides. The species like Arthrocnemum indicum, Suaeda Maritima are dominating species in

this ecosystem.

iii. Mangrove Eco-system

This type of ecosystem existed in western bank of the river Korattailar. This is dominated by

Avicinnia marine. Sesuvium Portulacastrum & Suaeda Maritima. These plants are periodically

washed by the tides and as result in some areas quick sands are noticed.

iv Marsh Eco-system

The marshes are essentially fresh water supporting variety of plant. Acacia nilotica and

Azadirachata indica are the common species of the study area.

v. Agro Ecosystem

Rice and banana species of plant are the main species of this ecosystem.



60

vi. Flora

The field investigation and satellite imagery data show, that the study area is a mixture of

agricultural, wasteland and get irrigated by the tanks and tube wells.

The dry tropical vegetation is observed within the study area. The experimental finding of the pre

monsoon season shows the dominance of grasses like Cyanodon followed by Parthenium

hysterophorous, Croton sparsiflorus & Odina odiya and trees like Acacia nilotica, Azadirechta

indica, Anona squamosa, Delonix regia, Ficus benghalensis within the study area.

vii. Fauna

The domestic animals are mainly mammals. The domestic animals present in the study area are

listed in the Table – 3.14.1

viii. Wild Animal

Since the natural forests constitute negligible of the forest area and since they are in isolated

pockets, the wild life does not offer a wide spectrum of species. Wild animals are rarely seen due

to absence of natural dense forest and land occupied by human being. The wild animals like

Nilgai, Jackals, Fox and Rabbit have drastically reduced due to increase in human population and

clearance of wild flora for making residential and commercial land. Other than these, some

reptiles and amphibians can also be seen with a number of bird species.

A list of birds, reptiles, amphibians and rodents based on information gathered from local

inquiries is presented.

3.10.2 Aquatic Ecology

The specific biological species (Fishes, Phytoplankton, Zooplankton etc.) for a particular

environmental conditions are the best indicators of environmental conditions are the best

indicators of environmental quality. Information on the environmental stress due to the impacts

of any industrial activities on the community structure serves as inexpensive and efficient early

warning and control system to check the effectiveness of the measures to prevent damage to a

particular ecosystem.

a. Planktons

Phytoplankton and Zooplankton are indicators of environmental stress. The quality and quality of

such biological species in a particular environmental largely depends on various physicochemical

characteristics of water such as pH, Conductivity, nutrients, BOD, alkalinity etc.,



64

b. Fishes

The fishes/ aquatic fauna of the study area is reported based on the field sampling and confirmed

by the local people and secondary data provided by Thiruvallur district office is listed. The fishes

like Chirocenttrus, Lesser Sardines, Thriossocles, Anchoviella, Flying Fish, Sciaenids, Caranx,

Education:

The literacy has well connected with the growth rate of the economy, birth rate, death rate,

infant mortality rate (IMR). The district has good primary and secondary education infrastructure

in urban and rural areas.



70

The literacy rate is 84% which is higher than same of Tamil nadu (80%) and of India(73%).

The literacy rate has been the major determinant of the rise or fall of the other indicators.

The accessibility of Primary and Upper Primary education is paramount importance for

increasing literacy rate as well as reducing the dropout rate. One of the main reason for the

falling dropout rate due to the distance to the schools is at minimal distance.

The Corporate Social Responsibility

The Corporate Social Responsibility commitments in respect of project area development will

be priority for the villages .

In the context of public sector enterprises Corporate Social Responsibility (CSR) should be viewed

as a way of conducting business, which enables the creation and distribution of wealth for the

betterment of its stakeholders, through the implementation and integration of ethical systems

and sustainable management practices.



74

In the guidelines (Guidelines on Corporate Social Responsibility And Sustainability For Central

Public Sector Enterprises, (F.No.15(13)/2013-DPE(GM) dt 21.10.2014), has emphasized of CSR

and Sustainability is clearly on capacity building, empowerment of communities, inclusive socio-

economic growth, environment protection, promotion of green and energy efficient

technologies, development of backward regions, and upliftment of the marginalised and under-

privileged sections of the society. In their normal business activities, public sector companies

should try to conduct business in a manner that is beneficial to both, business and society. They

are prompted to use social responsibility and sustainability initiatives for business gains as well as

social value creation through adoption of “shared value” approach, wherever possible in their

routine business operations.

The Corporate Social Responsibility commitments in respect of project area development will be

priority for the villages .

1.Education: Providing infrastructure to Primary and Secondary schools by constructing new

building or rehabilitating the existing building, provisions of excellence award to the topppers,

strengthing the labs and libararies.

2. Health- Campaign for Health awareness and sanitation , contributing infrastructure and

equipments to Rural Health centres, Conducting health camp for Vaccination, Eye care, maternal

4 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

4.1 ENVIRONMENTAL IMPACTS

The methodology adopted for carrying out the Environmental Impact Assessment for the proposed

Project has been based on the Guidelines issued by Ministry of Environment & Forests (MoEF & CC).

An effective environmental impact assessment calls for establishing sufficient background data on

various environmental components through reconnaissance survey, sampling and available literature

sources etc. The proposed project will have impacts on the environment in two distinct phases.

During the construction phase which may be regarded as temporary or short-term; the other during

the operation stage, which will have long term effects.

The impact identification of each of the environmental parameters is the first step of assessment. In

order to identify the impact comprehensively, all the activities associated with the proposed project

during the construction as well as operational phase are identified and listed. A careful examination

of each of these activities with respect to the environmental components establishes a “Cause and

Effect” relationship between the activity and environmental parameters.

4.2 Activities during Construction Phase

During the construction phase, the following activities among many are considered to be important

towards creating environmental impacts:

a) Site preparation (fencing, boundary & clearing of site)

b) Excavation, backfilling and leveling

c) Hauling and dumping of earth materials & construction spoils

d) Foundation works

e) Fabrication erection of Steel structures such as, Tanks, Pipelines and Sheds.

f) Construction of internal roads, drains & water supply

g) Painting and finishing



78

h) Clean up operations, landscaping and plantations

The activities can be divided into two categories, viz.

Sub-structural

Super-structural work.

Sub-structural construction work will involve cutting of trenches, excavation, concreting etc. All these

activities will give rise to dust pollution. The super-structural work will involve concrete & masonry

work etc. and will involve construction equipment like cranes, concrete mixers, hoists, welding sets

etc. There may be dust, gaseous and noise pollution from these activities. Concrete and masonry

works involve considerable amount of water, which generally induce certain impact on the local

water source.

Mechanical erection work involves extensive use of mechanical equipment for storage,

transportation, erection and on-site fabrication work. These activities generally produce some air

contaminants and noise pollution. On the other hand electrical work is less polluting- in general. The

main sources of pollution & impacts during construction phase are cutting of few trees, dust

generation, noise generation by construction equipment & traffic, inflow of construction labour,

sediment load in construction water, and generation of solid waste in the form of construction spoils.

4.3 Activities during Operational Phase

During the operation stage, there will not be any significant sources of pollution & impacts. The main

activity during operation is transfer of petroleum products (like MS & HSD) and spillage of such

products at certain intermediate points.

4.4 Impacts during Construction Phase

Project activities during construction phase include laying of pipeline and construction of Oil Storage

Terminal. These activities will result in dust generation, noise generation by construction equipment

& traffic, inflow of construction labour, sediment load in construction water, and generation of solid

waste in the form of construction spoils.



79

Therefore, construction phase activities would have moderate impacts on on-site noise & air quality,

land use and ecology. It could also develop minor impacts on on-site soils, water use and water

quality. The other impacts of construction phase will be small in magnitude as well as temporary in

nature and are expected to wear out gradually once the construction activity is completed.

4.4.1 Impacts on Soil

The level of the entire site area will be raised by filling and suitable garden soil filled in areas where

Green Belt/ Landscaping are proposed.

4.4.2 Mitigation Measures

Plantation & turfing wherever needed in the project site would be undertaken to appease the

chances of soil erosion. Construction materials would be stored in godowns or enclosed spaces.

4.4.3 Impacts on Land Use

Preparatory activities like construction of access roads, temporary offices, quarters and godowns,

storage of construction materials etc. will be confined within the project area. These will not

generally exercise any significant impact except altering the land use pattern of the proposed project

sites. There will be no impact on the adjoining land.


Construction camp for construction personnel to avoid indiscriminate settlement of construction

labourers. The small amount of construction debris will be disposed of in suitable pre-identified

areas/ low lying areas along as per the advice of local bodies. Appropriate dust suppression measures

will be implemented within the project site during construction, material handling.

4.5 Impacts on Hydrology and Water Use

4.5.1 Impacts on Hydrology

No impact on hydrological regime as the project will not obstruct the water flow in rivers & canals

during construction. Drainage pattern of overland water flow of the storage terminal will be changed

according to the existing profile and slope of the land.


The water demand during construction period will be met from the private water suppliers/ Metro

water therefore, not likely to have impacts on other users.



80

Water Quality

4.5.3 Impacts on Water Quality

Wastewater from construction activities would contain suspended impurities. Deterioration of water

quality due to wastewater disposal from the workers camp and sullage generated from construction

sites.


The construction activities would be limited to small area. Proper sanitation and drainage facilities

would be provided at the construction site.

4.6 Air Quality

4.6.1 Impacts on Air Quality

Generation of dust due to excavation, backfilling & hauling operations and transportation.

Deterioration of air quality due to emission from construction machineries and automobile traffic.

4.6.2 Mitigation Measures:

Construction materials would be stored in godowns or enclosed spaces. To reduce fugitive dust

emission at the proposed site due to vehicular movement and material transportation, sprinkling of

water would be undertaken wherever unpaved haul roads pass through habitation. Low emission

construction vehicles and generator sets should be used. Construction machinery should be in good

working condition and engines turned off when not in use.

4.7 Noise Quality

4.7.1 Impacts on Noise

During the construction phase, noise will be generated due to movement of vehicles, and operation

of light & heavy construction machineries including pneumatic tools (bull dozers, scrapers, concrete

mixers, generators, pumps, vibrators, cranes, compressors etc.) that are known to emit sounds with

moderate to high decibel value. Noise generated from sources mentioned above will be intermittent

and of short duration mostly during daytime.

Therefore, no significant impact is anticipated on account of noise generation around the project

site. Moreover, villages/settlements being mostly far away from the site, no significant impact on



81

local people are apprehended, as the noise will generally die down by the time it reaches them.

However, the workers are likely to be exposed to high noise levels that may affect them.

Careful planning of the operation of construction equipment is required during this period so that

minimum disturbances are caused. Construction camp would be located away from the construction

sites and major road traffic.


Impacts of noise on construction workers shall be minimized through adoption of adequate

protective measures in the form of

(a) Use of personal protective equipment (ear plugs, ear muffs, noise helmets etc.),

(b) Education and public awareness, and

(c) Exposure control through the rotation of work assignments in the intense noise (above 90 dBA for

8-hr exposure as per Factories Act) areas.

Low noise construction equipment should be used. It would be ensured that all the equipment used

during construction are properly maintained to keep noise within the permissible limits. Construction

machinery should be in good working condition and engines turned off when not in use.

4.8 Flora & Fauna

4.8.1 Impacts on Flora

Loss of flora due to construction of the proposed Oil Storage Terminal.

4.8.2 Mitigation Measures:

Plantation in the open spaces of the project site is proposed to be implemented under plantation

programme.

4.8.3 Impacts on Fauna:

No impact on fauna during construction as the project site is a barren land.



82

4.8.4 Impacts on Aquatic Life

As the water quality of the surface water bodies is not likely to change due to the construction

activities, no impacts on the aquatic life is expected.

4.9 Impacts on Socio-economics

Impacts on Employment & Trading Opportunities

Substantial construction personnel including skilled, semi-skilled and unskilled labourers will be

employed by various contractors at site during the peak period of construction phase. The

construction materials like stone chips and sand will be procured locally.

4.10 Impacts & Mitigation Measures During Operation Phase

Project activities during operation phase include transfer of petroleum products through the pipeline

under pressurized flow and tap off of such products at certain intermediate points. These activities

will result in enhancement of chemical hazards and socio economic benefits. There will have as such

no other sources of pollution & negative impacts.

Therefore, operation phase activities would have moderate impacts on socioeconomics. It could also

develop minor impacts on noise. The main impacts of operation phase are chemical hazards and

socio-economic benefits and such operational impacts are long term.

4.10.1 Soil

4.10.1.1 Impacts on Soil

Generation of dust in the project area due to soil erosion.

4.10.1.2 Mitigation Measures

The soil conditions of the project site would be allowed to stabilize during this period after the

impacts of the construction phase. The top soil in non-built up areas of the project site would be

restored and such portions of the site would be subjected to plantations which would help in



83

bonding together of the soil, thus increasing its strength. Laying of roads and internal pathways will

reduce top soil erosion.

4.10.2 Water

4.10.1.3 Impacts

Drainage water from the site. Regular water requirement for operation & maintenance. The Effluent

Treatment Plant receives oily water through a separate drain line connecting tank farms, TT Gantry

area, Pump house manifold area etc.

4.10.1.4 Mitigation Measures

Effluent Treatment Plant of capacity 50 KL/HR and Sewage treatment Plant of capacity 6 KLD is

planned for the proposed project. Treated water from ETP will be used for gardening. Appropriate

drainage facilities will be developed within the site including proper disposal to drains. Regular water

requirement would be met from private water suppliers. Adequate water will be stored for fire

fighting in fire water storage tanks.

4.11 OPERATIONAL PHASE IMPACTS

Because of its potential to create long-term impacts, this phase is very important from the

environmental impact point of view. The basic impacts like gaseous emissions, water

consumption/ pollution and solid waste will have the potential to adversely affect air, water

and land / soil in the vicinity of the project site.

AIR ENVIRONMENT

Base line data reveals that ambient air quality in the study area for the Parameters PM2.5,

PM10, SO2, NO2, are well within the permissible Limits as prescribed by the National Ambient

Air Quality Standards (NAAQ’S) for Industrial Area, Residential, Rural & Other area. Stack

Emission of PM, SOx & NOx are attached to DG’s are the source of air pollution.

METEROLOGICAL DATA

The site specific meteorological data for three months from February 2015 to April 2015 were

obtained from onsite metrological station. Other data included for AERMET were daily wind

speed, wind direction, temperature, relative humidity, air pressure, precipitation, and solar



84

radiation recorded during the period. AERMET reformats meteorological data so that it can be

used as input for AERMOD model.

AERMET PROCESS

For the 3 phase AERMET processing of the meteorological data, specifications of the land

use in the area are required to determine the terrain roughness for modelling. The land use

was characterized for in and around the site. The surface characteristics for the site and

surroundings were selected and used to calculate the albedo, Bowen ratio, and surface

roughness parameter. The meteorological data were processed in the AERMET software to

generate wind flow pattern & to generate surface meteorological data and profile

meteorological data in a prescribed format that can be fed to AERMOD for modeling.

AERMOD PROCESS

AERMOD Software Version 7.5.0 was used for air dispersion modelling and is applicable to a

wide range of buoyant or neutrally buoyant emissions up to a range of 50km. In addition to

more straight forward cases, AERMOD is also suitable for complex terrain and urban

dispersion scenarios.

AERMOD is a steady-state plume model. In the stable boundary layer (SBL), it assumes the

concentration distribution to be Gaussian in both the vertical and horizontal. In the

convective boundary layer (CBL), the horizontal distribution is also assumed to be Gaussian,

but the vertical distribution is described with a bi-Gaussian probability density function

(pdf). This behaviour of the concentration distributions in the CBL was demonstrated by

Willis and Deardorff (1981) and Briggs (1993). Additionally, in the CBL, AERMOD treats

“plume lofting,” whereby a portion of plume mass, released from a buoyant source, rises to

and remains near the top of the boundary layer before becoming mixed into the CBL.

AERMOD also tracks any plume mass that penetrates into the elevated stable layer, and

then allows it to re-enter the boundary layer when and if appropriate. For sources in both

the CBL and the SBL AERMOD treats the enhancement of lateral dispersion resulting from

plume meander. The emissions from existing and proposed stacks have been taken as basis

for modeling and are shown below:

5 ENVIRONMENTAL MANAGEMENT PLAN

Environmental Management Plan (EMP) is the key to ensure a safe and clean environment. The EMP

envisages the plans for the proper implementation of mitigation measures to reduce the adverse

impacts arising out of the project activities.

EMP has been prepared addressing the issues like:

Mitigatory measures for abatement of the undesirable impacts caused during the

construction and operation stage.

Details of management plans (Greenbelt development plan, Solid waste management plan

etc.).

Institutional set up identified & recommended for implementation of the EMP.

Post project environmental monitoring programme to be undertaken after commissioning of

the project.

Expenditures for environmental protection measures.

The environmental mitigation measures for construction and operation phases has been given

below:

5.1 Environmental Management Plan During Construction Phase

Environmental impacts during the construction phase can be attributed to the site preparation

activity and the mobilization of workforce. The impacts of the construction phase on the

environment would be basically of transient nature and are expected to wear out gradually on

completion of the construction programme. However, once the construction of the project is

completed and its operations started, these operation stage impacts would overlap the impacts due

to the construction activities.

In order to mitigate such impacts and restrict them within tolerable levels, the following measures

shall be adopted:



90

1. Proper and prior planning of approach and access roads, and appropriate sequencing and

scheduling of all major construction activities.

2. Adoption of appropriate soil conservation programme and its timely implementation in the

proposed project site.

3. Initiation of an appropriate landscape programme including plantation of trees and flowering

plants in and around the project site particularly, at all available spaces which would serve the dual

purpose of controlling fugitive dust and abatement of noise levels in addition to improving the

aesthetics of the area.

4. Water sprinkling in the vulnerable areas to suppress the dust generated during excavation, leveling

and other operations.

5. Use of properly tuned construction machinery & vehicles in good working condition with low noise

& emission and engines turned off when not in use.

6. Control of quality of construction wastewater within the construction site through suitable

drainage system with traps for arresting the sediment load for its proposed disposal into the main

natural drainage system around the site.

7. Implementation of suitable disposal methods of sediment/ construction debris at designated

places to avoid water logging at construction site.

8. Provision of protective gears such as ear mufflers etc. for construction personnel exposed to high

noise levels and locating the temporary labour sheds for housing the construction labourers away

from the construction site.

5.2 Environmental Management Plan During Operation Phase

The following mitigation measures shall be adopted during the operation phase of the project so as

to minimize the impact :

1. Regular monitoring for various components of environment should be undertaken to ensure

effective functioning of pollution control measures as well as to safeguard against any

unforeseen changes in environment.



91

2. Provision of Floating Roof for various Storage Tanks will reduce the emissions of Vapors into

the Atmosphere.

3. The liquid effluents from the project are suitably treated in Effluent Treatment Plant. Sewage

Treatment Plant for treating canteen and sanitary waste water. Excess effluent, if any, would be

let out of the premises, after satisfying the stipulated regulatory standards.

4. It should be ensured that all the pollution control systems are commissioned as a part of main

plant equipment, before the commencement of operation of the project.

5. Noise pollution will be controlled by proper maintenance & acoustic enclosure for pumps,

compressors & DG sets. Personal protective equipment for people working in high noise areas

6. Greenbelt will be maintained properly including replacement of the decayed trees and raising

of seasonal flowering plants.

7. Adequate safety measures complying to the occupational safety manuals to prevent accidents

/ hazards to the workers.

8. Adequate fire fighting system and fire water tanks will be provided at all stations.

9. Adequate safety equipment will be available within the project site.

10. OFC based communication system (including data and voice mail)

11. Adequate protection against stray current and interference will be provided.

5.2.1 Greenbelt Development Plan

The green belt has been recommended as one of the major components of the EMP which will

further enhance the environmental quality through:

1. Mitigation of air pollution problems

2. Attenuation of noise level

3. Maintain the bio diversity of the area and improve aesthetics.



92

For maintaining the ecological balance, dust control and mitigate noise pollution, greenery is

proposed to be developed to the maximum extent as permitted by the lay out along the proposed

plant boundary and inside the plant.Green belt will also be developed in and around the project

area.

The green lawns and the water-bodies compliment the grace and symmetry of the buildings. The

nature of plantation comprises of trees, lawns, shrubs and roads and pathways.

Extensive plantation and landscaping is proposed to mitigate any impacts during this phase.

Development of a green belt in and around the building area is an effective way to check pollutants

and their dispersion into the surrounding areas. The degree of pollution attenuation by a greenbelt

depends on its height and width, foliage, surface area density, dry deposition velocity of the

pollutants and the average wind speed through the greenbelt.

The objectives of green belt management are:

To create a soothing environment for people to work

To mitigate vehicular emissions and noise pollution

To cultivate culture of greenery within and outside the project site.

To maintain landscaping by optimal use of resources

Garden waste is accumulated in a designated area and used in the composting pits.

Therefore, development of green belt is nowadays imperative around industrial complexes.

Adequate plantation programme in and around the project site And the following plants are

suggested:

5.2.2 Development of green belt will include:

1) Plantation along the boundary / periphery and all over the project site for protection against

particulate dispersion and noise dispersion. The peripheral greenbelt will vary in width to suit the

plant design requirement.

2) Plantation along approach road and pathways for protection against noise and vehicular

emissions.



94

The following general guidelines and measures will be adopted:

- The plantation of trees will be initiated with start of the construction stage so that substantial

growth may be achieved when the project is completed. The greenbelt development programme will

be drawn to conform to natural climatic conditions and adaptability of the species.

- Species involved in plantation / afforestation should include indigenous, fast growing and eco-

friendly.

- Proper drainage system and proper plantation techniques should be adopted.

- Plantation should be properly maintained and protected by fencing from grazing and felling. The

plantations would consist of a mixture of carefully chosen locally available species of trees, shrubs

and herbs, preferably evergreen and resistant to pollution.

5.2.3 Solid Waste Management

The sludge from ETP is treated by a process called Bioremediation. Bioremediation involves

detoxifying hazardous substances instead of merely transferring them from one medium to another.

This process is less disruptive and can be carried out at the site which reduces the need of

transporting these toxic materials to separate treatment sites. Solid waste from STP will be used as

manure.

5.3 SOCIO – ECONOMIC ENVIRONMENT

BPCL is committed to the socio – economic up – lift of the people in region and has actively involved

in formulating and implementing proactive measures as part of the corporate social responsibility.

The following activities are carried on by BPCL as a part of Corporate Social Responsibility (CSR).
