Executive Summary
Introduction
Oil and Natural Gas Corporation (ONGC) Ltd., a Government of India Navaratna
Enterprise, is awarded by Government of India an exploration block VN-ONN-2009/3 Son
Valley, Vindhyan Basin in Damoh district of Madhya Pradesh. This block was awarded to
ONGC in the NELP – VIII with 100% equity participation of ONGC. ONGC has signed
production sharing contraction with Govt. of India on 30th June 2010. For the proposed
block, Petroleum Exploration License (PEL) was granted on 12th October 2011for a total
period of 7 years distributed in two phases, phase –I of 4 years and phase –II of 3 years
durations respectively. The committed minimum work program (MWP) for the Phase-I was
280 GLK 2D seismic API which has been overachieved (API 288.81 LKM of 2D seismic
data) as on date. Based on the interpretation of new seismic data and integration with
available G&G data of the block and the contiguous area, a number of prospective locale
were identified in the block. One exploratory location, R-HAT-A, has been released by the
competent authority while 3 other prospective locale are identified in the block which can be
firmed up for release based on the drilling result of R-HAT-A. The entire block falls in
Damoh and Chhatarpur District in the state of Madhya Pradesh. However, lead area as
identified by ONGC team for exploration activities is in Damoh district only.
The exploratory well drilling of hydrocarbons in VN-ONN-2009/3block is included under
activities specified in Schedule (Activity 1b) of the new EIA Notification dated 14th September
2006.It requires Environmental Clearance (EC) from the Ministry of Environment and
Forests (MoEF&CC). The proposed project is new project and there are no ongoing and
previous operations of the proposed project, requiring environmental clearance exist in the
awarded block.
ONGC had submitted Form-1 of the EIA Notification, along with a Draft Terms of Reference
(ToR) for EIA study to MoEF&CC. MoEF&CC has issued approved ToR vide letter No. J-
11011/100/2014-IA II (I) dated 18th July, 2014. SENES India, a NABET accredited EIA
Consultant, has been entrusted by ONGC to undertake an Environmental Impact Assessment
(EIA) study for VN-ONN-2009/3 block.

Project Location
The VN-0NN-2009/3 Block is about 1250 sq. km. it is located in the in two districts of
Madhya Pradesh, namely Damoh and Chhatarpur. The block area is mainly covered with
agricultural land and forest land. Northern part of the block, outside of lead area is
dominated by forest land. However, there is no forest land in lead area identified by ONGC
for exploratory well drilling and other project activities. Major Town of Damoh district is
Hatta town (Tehsil Headquarter) comes in central part of the proposed block. The
geographic location of the VN-ONN-2009/3 Block is included within the Survey of India’s
Topo- Sheet No. 54P/07, 54P/08, 54P/11 and 54P/12.
Well Location
The proposed well sites have been selected in agricultural field. Environmental
considerations viz. location of sensitive ecological habitats, settlements, schools/ hospitals,
water bodies etc. has also taken into account while selecting the locations of wells. Proper
environmental and safety measures will be adopted to minimize footprints on these receptors.
Total 4wells are proposed within the lead area of VN-ONN-2009/3 Block during the plan
period. Out of 4 wells, location of one well “R-HAT-A” has been finalized based on seismic
data while three other locations are tentative.
Project Description and Activities
The objective of the exploratory drilling program is to determine the potential of commercial
hydrocarbon reserves within the block. This activity would involve
Well site preparation, strengthening of access roads,
Well drilling and testing.
Site closure and decommissioning for wells not indicative of potential hydrocarbon
reserves.
The estimated land required per drill site is approximately 3 ha including site required for
construction of approach road, which will be taken on temporary lease, after making
necessary payments against lease and crop compensation. All proposed drill sites are located
away from human habitation. Therefore, displacement will not be required for the project. As
displacement is not required, resettlement and rehabilitation is not hold pertinent for this
project. Additionally, it is to be mentioned that, no rehabilitation and resettlement is required
during construction or strengthening or widening of approach road to reach to drill
site.Drilling waste management for the proposed exploratory drilling will be in accordance
with CPCB and M.P Pollution Control Board (MPPCB) norms.
Project Utilities and Resource Requirements
The power requirements at the site preparation and construction phase for the drill site will
be met by 2 nos of 1215 KVADG Sets. Out of 2 sets of DG one will be kept as standby all the
time for emergency. During the drilling phase, about 8 KLD of High Speed Diesel (HSD) will
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 3 ONGC
be required. Fuel will be supplied onsite by local supplier through mobile tankers. Out of
this, a major part comprising about 85% will be consumed by the rig (also include the DG
sets) and about 15% will be required for the campsite. Fuel in excess approximately 56 KL (7
day’s reserve) will be stored at onsite storage facility as per Petroleum Rules, 2002 in a
paved and bunded area.
Total water requirement/day for the drilling operation including domestic usage is estimated
to be about 25KLD. Out of 25 KLD, 8 KLD is estimated for rig operations 15 KLD in mud
operations, while 2 KLD will be required for domestic usage. The total projected average
consumption of water during the drilling phase of 120 days will be about 3000 KL per well
including domestic purposes. Water will be sourced through the local available sources.
ONGC will take permission from Ground Water Authority regarding abstraction of ground
water for industrial purposes if required.
Waste generation
Drilling mud and cuttings, domestic wastewater, waste oil and kitchen waste will be
generated during drilling activities. Approximately, 200m3/d of drill cutting per well,
approximately 6.4m3/d of drilling wastewater and around 5m3/d of waste drilling mud is
anticipated to be generated during drilling activities. Approximately, 12kg per day of solid
kitchen waste will also be generated from onsite camp facility. Minor quantities of oily rags
and waste oil generation are also anticipated from proposed project activities.
Baseline Environmental Status
To understand the existing physical, biological and socioeconomic environmental situation,
both primary and secondary data was collected. Stakeholder consultations during primary
survey with relevant State Government officials and heads of Gram Panchayats and local
villagers were carried out to obtain secondary information regarding the block. The villagers
of the block were informed of the upcoming project and their opinion on the same was
recorded during the consultation.
Climate and Meteorology
Meteorological data for the study area is collected obtained from the primary monitoring
conducted at Hatta town during Jan-Feb 2015. During the study period the maximum
temperature ranged between 26.2˚C to 37.5˚C and the minimum temperature ranged from
21.2˚C to 28.7˚C.The mean of daily maximum and minimum Relative Humidity (RH) was
recorded as 97% and 19% respectively during the primary monitoring study. The
predominant wind direction was observed to be from South for the study period. The average
wind speed for the study period was 1.3 m/s. The wind in the study period blew at a speed of
0.03m/s to 7.47 m/s
Ambient Air Quality
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 4 ONGC
The ambient air quality is monitored at 8 representative locations of the block. The average
of 24 hourly PM10 at the monitoring locations ranged between 70-107.7μg/m3.At two
locations the PM10 concentrations were observed not to be in compliance to the NAAQS (100
μg/m3). The reason for a slight exceed of PM10 at these places might be the farming activities,
harvesting, movement of cattle’s, vehicles and tractors etc. Average concentrations for PM2.5,
NOx and SO2 concentration in all monitoring stations is found well within NAAQS standards.
Average values for methane hydrocarbons at the sampling stations varied between Below
Detectable Limit (BDL) and 1.1 ppm whereas the concentration of non-methane hydrocarbon
at all sampling location found to be between BDL and 0.4 ppm. Average TVOC concentration
of all the sampling location was found to be Below Detectable Limit.
Ambient Noise Quality
The day time and nighttime equivalent noise levels varied between 50.5 -58.6 dBA and 42.4-
45.3 dBA respectively. The day time equivalent noise levels at Hatta town had the highest
values whereas Motha village had the lowest amongst all stations. The national standard for
noise level in the residential areas during day time is 55 dBA. The night time equivalent noise
levels for all the monitoring stations were found to be in compliance to the night time noise
standards (45 dBA) except at Hatta Town where night time noise level was marginally high
(45.3 dBA) as compared to NAAQS for residential area.
Groundwater Quality
Turbidity values in all sampled water found <1.0 NTU which shows that all the drinking
water sources (mostly tube wells) meet the acceptable limits as per IS 10500:2012. The Total
Dissolved Solids (TDS) values for the potable water samples analyzed varies in the range of
594 mg/l (at Ghurata) 1346 mg/l (at Majhguwan Patol). TDS values at 500 mg/l or below is
considered to be acceptable for drinking being specified under IS 10500:2012 drinking water
standard. Only one sample meets the acceptable limits whereas rest of the samples although
exceeds the acceptable limits but well within the permissible limits.
Iron concentration of potable water samples collected from Ghurata village (0.42 mg/l)
exceeded the acceptable limit i.e. 0.3 mg/l as per drinking water standard. Rests of the
samples were found to be well within the acceptable limits. High iron content recorded in
groundwater from Ghurata village may be probably due to local geological features.
Fluoride contents in the potable water samples were found to be within the permissible limits,
although the sample collected from Hatta town exceeds the acceptable limits.
The monitoring results showed that the concentration of heavy metals (chromium, copper,
zinc, mercury, cadmium. lead, nickel, arsenic etc.) is within acceptable limit as per IS
10500:2012 standards.
Surface Water Quality
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 5 ONGC
The pH of the all analyzed surface water samples found to be slightly alkaline in nature and
varied from 7.24 to 7.42. The dissolved solids content varied between 274 to 344 mg/l while
the electrical conductivity varied from 411µS/cm to 500µS S/cm. The Dissolved oxygen (DO)
values ranging from 3 to 6.1 mg/l indicating moderate to favorable conditions for the growth
and reproduction of normal population of fish and other aquatic organisms in the these water
bodies. As the surface water sources are not used by the locals for drinking purposes and
mostly the river/stream water exclusively is being used for irrigation purposes, the water
quality is compared with the CPCB prescribed water quality criteria- Class- E (Irrigation,
Industrial Cooling and Controlled waste disposal). Class- E does not have any criteria for
DO or BOD. The DO level from all the stations even meets the standard of Class-C
(Drinking water source after conventional treatment and disinfection).
BOD values in all the surface water samples were ranged between 2.8mg/l and 12 mg/l. The
maximum value (12 mg/l) recorded from downstream of Sonar River at Hatta Town. Low
BOD values confirmed the presence of low concentrations of biologically oxidizable organic
matter in the receiving water bodies. However, where the BOD level recorded as 8, 9 and 12
mg/l respectively, could be due to the discharge of domestic wastewater from the nearby
settlements/town and runoff from agricultural fields. The presence of oil and grease content
in all surface water sources was found to be negligible (between <0.5 and 0.62 mg/l). Heavy
metal concentrations such as Mercury (<0.001mg/l in all samples), Lead (<0.005 mg/l in all
samples), Hexavalent Chromium (<0.03 mg/l in all samples), Copper (<0.05 mg/l in all
samples) and Nickel (<0.005 mg/l in all samples) found to be negligible and well below the
WHO guideline values.
Land use
The land-use and land-cover of the Block has been interpreted from the, toposheet of the
area, and subsequently by ground truthing during field surveys. The study area land use
shows that majority of the land within the Block (62.72%) is agricultural land. Rivers and
drains comprise of 2.28 % of the total Block area. Forest areas are near 31.8 % of the total
Block area. However, all the forest area is outside of lead area. Settlements comprise of 1.82
% of the total Block area. Road network including State Highway and other small roads
comprise of 0.05 % of the total Block.
Soil Quality
From the texture point of view, the soil from 4 locations out of 5 sampling locations, are
found to be clayey in nature, having good capacity for adsorption and retention of water and
plant nutrients. Therefore, it is suitable for agriculture and plantation. The soil sampled from
Ghurata village shows that the soil has more silt than clay and the texture of the soil is silty
clayey in nature.
Traffic Survey
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 6 ONGC
Movement of Two & Three wheelers (a total of 453, comprising 42 %) was recorded high in
comparison to other category of vehicles on SH-51.The maximum movement of vehicles was
recorded during 12 p.m. till 6 p.m. Movements of four wheelers (light vehicles) were
recorded higher in numbers (509) with 37% of total vehicular movement on Damoh-Hatta
State Highway (SH-49). The highest number of vehicles was recorded from Light Motor
Vehicles/four wheeler on SH-37 (Hatta Town to Patera Road). The contribution of these
vehicles was 38% with a total number of 405 out of 1076.
Natural hazards
The study area is located in Zone III as shown in the Bureau of Indian Standards (BIS) 2000
seismic zone map for India. Zone III is defined as region which might encounter earthquakes
of intensity VII (MSK).
Floods are common in Damoh and Chhatarpur district because of basin of major rivers such
as Ken and Sonar River. On 5th July 2005, Damoh, Chhatarpur and other districts of north
eastern part of Madhya Pradesh were badly affected by flash floods triggered by heavy rains.
Due to heavy rain, all the major rivers including Ken and Sonar were overflowing. As
reported by the villagers residing near the Kopra River, settlements near the river and
various seasonal drains got affected by water logging. The main causes of flash floods in the
area are:
Obstruction in drainage system due to heavy rainfall
Increase in siltation in riverbeds due to erosion in the catchment areas.
Change of river course because of poor natural drainage system.
Biological Environment
The proposed project site in M.P state lies within the bio-geographic province-6A, Deccan
Peninsula- Central Highlands. The Panna National Park is located 17 km from the proposed
drilling site and Nauradehi Wildlife Sanctuary is located at 42 km from the proposed drilling
site. The other protected areas namely Ken Gharial WLS, Panna (Gangau) WLS and
Veerangna WLS are located at distances of 58 km, 43 km and 54 km respectively.
The forest type of this region is mainly 5A/C3- Southern Tropical Dry Deciduous Forest and
mostly dominated by teak. During the primary survey and as per the working plan of Damoh
Forest Division, the most of the vegetation of these forests are found to be mixed type.
The tree species which were identified from the forest areas such as Sagwan, Saj, Salai,
Seja/Lendia/Senha, Haldu, Shisham, Reunjha, Mahwa, Safed shirish, Babool, Bija sal,
Behera, Palash, Neem, Tendu, Dhaman, Dhawra, Dhobin, Jamun, Arjun, Aam, Imli,
Harshingar, Amaltash, Doodhi, Ber, Kachnar, Kewlar. The shrubs were mostly Adusa, Aak,
Kalabasa, Karounda, Errand, Jhadneri, Van tulsi, Nirgudi, Woodfordia fruticosa Dhabai,
Pawar/chakauda, Besharam, and Lantana etc. The herbs and climbers were recorded from

SENES 7 ONGC
the reserved forest and private forest areas were apamarg, Gokhru, Xanthium Godhru,
Chireta, Bhatkatiya, Gunja, Kiwanch, Bechandi, and Mahul etc. Grass/sedges species such
as Kaans, Kush, Kusul, Khas, Gunher, Jhani, Doob, Phool bahari.
During the primary survey, species such as Common Langur, Rhesus macaque, Jackal,
Common Mongoose were sighted around the forested areas. The herbivores such as Nilgai
were also recorded during this survey. Dialogue with the local villagers and forest officials
had confirmed the presence of striped hyeana, Common India Porcupine, Common Indian
hare, wild boar in these forested areas. Dialogue with the local villagers does confirm the
presence of poisonous, non-poisonous snakes and other reptilian species in this region. These
include the cobra, common Krait, Russell’s viper, monitor lizard.
Socio economic
The proposed project falls under following tehsil- Hatta, Batiyagargh, Patera and Patharia
district- Damoh.Hatta is the biggest Tahsil in Damoh district in the state of Madhya
Pradesh, India. The sex ratio of the district is 910 females per thousand males. With respect
to the study area, the total population of the study area is about 98, 097 out of which 51,568
are males and 46,529 females. Of the study area villages, Batiyagargh has the highest
population (8951) and Manpurahas the lowest (299).
Other than Hatta Town, Batiyagarh is the only village, which has Primary Health Centre
available. Other facilities like maternity and child welfare centers, Nursing home’s and
private medical practitioners are majorly located between 5 kms and 10 kms or more than
10km of a distance from the villages. The drinking water facilities are satisfactory. It has
been found that there are rivers, ponds in the vicinity of the project site and the study area
villages. The villagers avail the well/tank/tube and hand pump water to satisfy their daily
drinking water needs.
Environmental Impact Assessment
The potential impacts of the project on different components of the environment is
systematically identified and evaluated for significance. The main concerns that emerged are:
Impact on air Quality
The operation of DG sets during drilling on site will result in the generation of air pollutants
viz. PM and NOx, which may affect the ambient air quality temporarily. In order to predict
the incremental values of air pollutants and resultant Ground Level Concentrations (GLCs)
at various distances intervals from the source of the above mentioned pollutants, an air
modeling is carried out by using ISC3ST model.
The maximum ground level concentration (GLC) for PM and NOx, due to DG set operations
are 0.15 and 0.03 µg/m3respectively at a distance of 1km in the SE from the centre of the
project site. The maximum GLC of NOx due to flaring operation is 2.62 µg/m3at a distance of
1.5 km SE.
Impact on Noise Quality
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 8 ONGC
The noise generated from drilling rig is considered to be about 95.0 dB (A) at a distance of
10m from the rig location. Noise attenuation equations (without any noise barrier) show that
the normal attenuated noise at any receptor points located at a distance of about 100 m and
200 m from the fence-line of the rig, will be in the range of about 75.0 dB(A) and 68.9 dB(A)
respectively. In the absence of an acoustic barrier, the predicted noise levels were found to
exceed the day time noise standard (55 dB (A)). However, with the introduction of a noise
barrier (5 m in height) at the fence-line will be enough to decrease noise levels near sensitive
receptors at 200m to about 56.9 dB (A). However a detailed noise modelling exercise to look
at option of noise reductions will be conducted at the design stage to determine the barrier
specifications.
Impact on Soil Quality
Stripping of top soil will be affecting the soil fertility of the well sites. Further, sourcing of
borrow material from agricultural fields, improper storage and handling of drill cuttings,
waste, fuel and chemicals may contaminate the soil. Site preparation activities may also
result in increased soil erosion and degrade soil properties. Specific mitigation measures will
be implemented by the proponent to stabilize the top soil, to preserve their fertility
characteristics during site restoration. Further, adequate measures will be taken for storage
and handling of waste, fuel and chemicals to avoid any soil contamination. The impact is,
therefore, considered to be of low significance.
Impact on Surface Water Quality and Hydrology
The surface run off from drilling waste (cuttings and drilling mud) is likely to be polluting
source leading to the pollution of receiving water bodies viz. natural drainage channels,
ponds etc. However, taking into account the provision of onsite drainage system and
sediment control measures to be implemented by the proponent and discharge in compliance
with the CPCB Inland Water Discharge Standards, the impact is considered to be of medium
significance.
Impact on Ground Water Quality
Sourcing of water for proposed project from local ground water resources may have adverse
impact on ground water availability in the area. However, considering the limited water
requirement (25m3/d) for a small duration of drilling period (say 120 days), the impact in
terms of ground water availability will be of low significance. Poor casing and cementing of
wells and improper storage of drill cuttings and mud may contaminate ground water.
Impact on Biological Environment
Impact on local ecology due to proposed exploratory drilling activities is assessed in terms of
loss of flora and fauna, impacts on avifauna, impact on aquatic habitats and loss of
ecological productivity in agricultural fields. The impacts on local ecology will be like
clearing of ground vegetation, disturbance due to noise and light, wastewater discharge, loss
of fertility due to top soil stripping etc. However, the proposed drilling is a temporary activity
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 9 ONGC
and ONGC will adopt necessary mitigation measures to address adverse impacts on
biological environment.
Impact on Socio economic Environment
Proposed project will have positive as well as negative impacts on the local people. The
adverse impact includes temporary loss of land and related livelihood, safety risk due to
project transportation, influx of population. However, ONGC will ensure proper restoration
of temporarily acquired drill sites to avoid any impact on crop productivity.
The project will benefit the people living in neighboring villages by giving preference to them
in relation to direct and indirect employment associated with various project activities and
boosts the local economy.
Risk Assessment
Quantitative Risk Assessment (QRA) considered the systematic analysis and evaluation of
risks related to the exploratory drilling in the acquired block VN-ONN-2009/3. The QRA
involves the identification and evaluation of major risks, prioritizing risks identified based on
their hazard consequences and formulating suitable risk reduction measures in line with As
Low as Reasonably Practicable (ALARP) principle.
Major risks viz. blow out/loss of well control, process leaks/fire, non-process fire and
explosion and their resultant consequences viz. jet fire, pool fire, oil spill have been assessed
and evaluated through a risk matrix generated to combine the risk severity and likelihood
factor. Risk associate with exploratory drilling have been determined semi-quantitatively as
the product of likelihood/probability and severity/consequence by using order of magnitude
data (risk ranking = severity/consequence factor X likelihood/probability factor).
Significance of project related risks are then established through their classification heads
like high, medium, low, very low depending upon risk ranking.
Environmental Management Plan
Site-specific Environment Management Plans (EMP) is developed to prevent and mitigate
significant adverse impacts. Accentuated beneficial impacts will be implemented by ONGC
for the proposed project. Key mitigation measures specific to each management plan are:
(a) Pollution Prevention and Abatement Plan:
All vehicles, equipment’s and machinery used for construction will be subjected to
preventive maintenance as per manufacturer norms.
Test Flaring will be undertaken in accordance with CPCB Guidelines for discharging
of gaseous emissions for Oil and Gas Extraction Industry.
Preventive maintenance of DG sets is to be undertaken as per manufacturers’
schedule to ensure compliance with CPCB specified generator exhaust.
Installing acoustic enclosures and muffler on engine exhaust of DG sets to ensure
compliance with generator noise limits specified by CPCB.

SENES 10 ONGC
Installation and maintenance of effective run-off controls, including silt traps, straw
barriers etc. so as to minimize erosion.
Proper casing and cementing of exploratory well will be done to prevent
contamination of sub-surface aquifers.
(b) Waste Management Plan

Hazardous Waste (Management, Handling and Trans-boundary Movement) Rules,
2000.
(c) Road Safety and Traffic Management Plan
Clear signs, flagmen and signal will be set up in major traffic junctions and near
sensitive receptors and night time movement of vehicles will be restricted.
(d) Occupational Health and Safety Management Plan
All machines to be used in construction will conform to relevant Indian Standards (IS)
codes. These will be kept in good working order and properly maintained.
Contractor workers involved in handling of materials and chemicals will be provided
with proper PPEs.
Workplace must be equipped with fire detectors, alarm systems and fire-fighting
equipment.
Health problems of workers should be taken care of by providing basic health care
facilities.
(f) Cultural Heritage Management
Cultural and archaeologically important areas within the block will be
geographically mapped and communicated to the Contractor.
Consultations will be held with local communities in areas of identified cultural
importance prior to the commencement of operations.
(g) Emergency Response Plan
Drilling rig and related equipment to be used for exploratory drilling will be
conformed to international standards specified for such equipment.
Blow-out preventers and related well control equipment will be installed, operated,
maintained and tested generally in accordance with internationally recognized

SENES 11 ONGC
Appropriate gas and leak detection system will be made available at each drilling
location.
Adequate fire-fighting equipment will be provided in each drilling site
Public Consultation
As ONGC is proposed to do the exploratory drilling at in Luhari village, Patera Tehsil, in
Damoh district of M.P, the Public Hearing had been organized in Damoh only and it was
conducted as per the EIA notification dated 14th September, 2006. The draft EIA report,
along with Executive Summaries in English and Hindi were submitted to Madhya Pradesh
Pollution Control Board (MPPCB) for conducting public hearing. The objective of
conducting public hearing is to disseminate project related information among locals and
understand and address their concerns due to proposed project.
Conclusion
The implementation of proposed drilling activity will confirm the availability of oil and gas in
the area, which can lead to further improvement in infrastructure, employment & business
opportunities in the project area. All possible environmental aspects are adequately
addressed and necessary control measures are included in the EIA report to fulfill statutory
requirement. ONGC will strongly support benefits to the local people and the area as per the
policy framework and commits to take care of all the environmental concerns of the local
people.

1 Introduction
1.1 BACKGROUND
Oil & Natural Gas Corporation (ONGC) Ltd., a Government of India Navaratna Enterprise, is
awarded by Government of India an exploration block VN-ONN-2009/3 Son Valley,
Vindhyan Basin in Damoh and Chhatarpur Districts of Madhya Pradesh. This block was
awarded to ONGC in the NELP – VIII round of bidding. The awarded block has an area of
1250 Km2 and ONGC has 100% participative interest (P.I). Production sharing contract
(PSC) for the block was signed on 30th June 2010 and the license was granted on 12th Oct
2011 for a total period of 7 years distributed in two phases, Phase- I for 4 years (12.10.2011-
11.10.2015) and Phase – II for 3 years (12.10.2015-11.10.2018) respectively.
The committed minimum work program (MWP) for the Phase-I was 280 GLK 2D seismic
API which has been overachieved (API 288.81 LKM of 2D seismic data) as on date. Based
on the interpretation of new seismic data and integration with available G&G data of the
block and the contiguous area, a number of prospective locale were identified in the block.
One exploratory location, R-HAT-A, has been released by the competent authority while 3
other prospective locale are identified in the block which can be firmed up for release based
on the drilling result of R-HAT-A. Drilling of location R-HAT-A during Phase-I (planned for
drilling in 2015-16) will enable to establish the prospectivity of the block as well as entering
into Phase-II. This will be set off against the MWP of three wells in Phase-II of exploration.
Although entire block falls in two districts but lead area identified on the basis of seismic
survey findings comes in Damoh District only. The released well location “R-HAT-A” falls
in Luhari village of Patera Tehsil, Damoh District.
The exploratory well drilling of hydrocarbons in VN-ONN-2009/3block is included under
activities specified in Schedule (Activity 1b) of the new EIA Notification dated 14th
September 2006.It requires Environmental Clearance (EC) from the Ministry of Environment
and Forests (MoEF). The proposed project is new project and there are no ongoing and
previous operations of the proposed project, requiring environmental clearance exist in the
awarded block.
ONGC had submitted Form-1 of the EIA Notification, along with a Draft Terms of Reference
(ToR) for EIA study to MoEF. MoEF has issued approved ToR vide letter No. J-
11011/100/2014-IA II (I) dated 18th July, 2014. Compliance to ToR is presented at Table 1-1
and approved ToR is shown in Annex 1.

SENES 13 ONGC
SENES India, a NABET accredited EIA Consultant, has been entrusted by ONGC to
undertake an Environmental Impact Assessment (EIA) study for VN-ONN-2009/3 Block.
Additionally, in conformance to ONGC’s Environment and Safety Policy, an EIA study will
play an important role in formulating appropriate environmental management response for
the proposed drilling project. In this perspective, SENES India has strived to fulfill the
project objectives delineated in the section below.
1.2 PROJECT JUSTIFICATION
ONGC has endeavored to meet the energy requirements of the country. The rising population
and consequent increases in demands on petroleum has put a lot of pressure on the
government as in spite its best efforts, the country has to import oil from international market.
It is expected that the proposed drilling activity in VN-ONN-2009/3 block will meet the
challenges partially. With a view to meet the growing demand, the initiative for exploration
in relatively less explored areas is envisaged.
1.3 OBJECTIVE OF THE STUDY
The objectives of the EIA study are as follows:
Establish the prevailing baseline environmental and socio-economic condition of the
VN-ONN-2009/3 PEL Block and its surroundings along with the compliance needs
for environmental approvals to carry out exploratory drilling activity;
Assessing environmental and socioeconomic impacts arising out of the proposed
drilling activities;
Assess impacts resulting from the proposed project;
Recommend appropriate preventive and mitigation measures to eliminate or minimize
pollution, environmental & social disturbances during the life-cycle of the project,
ensuring compliance with environmental laws and regulation applicable ;
Integrating mitigative measures with existing ONGC’s environmental action plans
and management systems so that they can be implemented, monitored and suitable
corrective action can be taken in case of deviations;
Identifying and proposing alternative actions in terms of technology and practices that
may help in abating environmental or socio-economic impacts due to the project;
1.4 SCOPE OF THE STUDY
The basic scope for this study involves conducting of an EIA study to understand the
environmental and social impacts of the project and recommend suitable preventive/
mitigative actions through the Environment Management Plan (EMP). The lead area of the
proposed block has been identified by ONGC. Since the entire project activities and well
locations are limited within the lead area only therefore primary monitoring/information was
focused in lead area only. However, secondary information was collected and anlysed for the
entire block. The study isbased on the TOR approved by Ministry of Environment and
Forests (MoEF), Government of India vide letter- No. J-11011/100/2014-IA II (I) dated

been described below:
The Block is rectangular in shape having a dimension of approximately 37km in
length and an average of 34km in width. The northern part of the Block is mainly
occupied with reserved and protected forest while the middle and southern part of the
block is covered by agricultural field mainly.
Terrain in the middle and south part of the block is mostly flat land. A river known as
Sonar River is passing through the block and joins the Ken River outside the block in
north east direction. A number of seasonal drains and tributaries of Sonar River such
as Khopra Nadi and Baink Nadi exist within the block. No large reservoir within the
block was observed during the reconnaissance survey.
Majority of the area in the block is agricultural land. Hatta which is Tehsil
headquarter along with number of villages exist within the block. Agricultural fields
are mostly bi-cropped. Water of Sonar River and its tributaries is being used as source
of irrigation in nearby agricultural field whereas field located away from river and
tributaries uses ground water for irrigation purpose.
National Highways namely NH-34and State Highway SH-51, SH- 49 and SH-37
passes through the Block. All these are important roads connecting block with the
Hatta Tehsil and Damoh district.
The Ecological sensitive area and wildlife sanctuary in the region is Panna national
Park and Noradehi Wildlife Sanctuary however, they are located at an aerial distance
of 45 and 50 kms respectively from the block. There is no notified ecological
sensitive area or wildlife sanctuary exists within the block.
The major settlements within the Block are Hatta, Luhari, Batiya, Sitanagar, Mankora
etc. The Majority of the people living in this region have community based life style.

2.5 PROJECT ACTIVITIES AND SCHEDULE
The lifecycle of project activities for the proposed project has been divided into distinct steps
and each is described in detail in the subsequent sections and will take approximately three
months to complete drilling and testing activity at each well site.
The project lifecycle has been classified into three phases:
Pre-drilling activity
Site selection
Land acquisition
Site access road and drill site construction
Pre-drilling activities, mobilization and Rigging up

2.5.1 Pre-drilling Activity
The pre-drilling phase will involve the following activities:
Site Selection
All the locations selected by ONGC’s were based on seismic data acquisition and
interpretation. Suitable drilling locations were selected based on the physical (terrain and
access) and technical suitability.
Selecting drill site’s environmental considerations is as below:
Away from organized human habitats.
Easy access to area of interest
Away from river and water bodies
Land Acquisition
During the site selection process all the legal requirements will be considered for finalization
of the surface locations. The estimated land required per drill site is approximately 3 ha
including site required for construction of approach road. As the seismic interpretation for R-
HAT-A exploratory well is completed therefore location of this well is finalized and land has
been acquired on the lease for a period of one year. The details of the land taken on the lease
is given below:

SENES 36 ONGC
Rehabilitation and Resettlement
All proposed drill sites are located away from human habitation. Therefore, any displacement
will not be required for the project. As displacement is not required, resettlement and
rehabilitation is not hold pertinent for this project. Additionally, it is to be mentioned that, no
rehabilitation and resettlement is required during construction or strengthening or widening
of approach road to reach to drill site.
Approach Road and Site Construction
Construction of Approach Road
The approach road will be constructed by contractors appointed by ONGC. Since the location
of wells is proposed in agricultural field with very low density of trees, it minimizes the
requirement of tree cutting. Wherever required, culverts and drainage channel will be
maintained during approach road construction.
Drill Site Construction
Approximately 3 hectares will be required for each drill site to facilitate drilling and testing
activity Site preparation will involve all activities required to facilitate the transport and
operation of the drilling rig and associated equipments and machineries. The site preparation
activities would include leveling, filling and consolidation of the site for staging of the
equipment and machinery. Since the well’s sites are proposed in agricultural field, clearing of
vegetation at the drill sites and approach roads is minimized.Reinforced Cement Concrete
(RCC) will be used for the construction of foundation system. For making foundations of the
main rig structure, cast in-situ bored under- reamed piles of specified lengths will also be
used. Site preparation will also involve the following:
Construction of cellar pit 3m X 3m X 3m for installation of well head and BOP
Construction of HDPE lined pit of 3250m3 at well site for temporary storage and
disposal of drill cutting
Construction of HDPE lined water pit of 150m3 capacity
Septic tanks and soak pits to dispose the domestic wastewater at the drill site.
The transport of rig including ancillary equipments and camp facilities to the site is expected
to comprise around 100 trailer loads. Though the rig and related equipments will be directly
brought to site, spares, chemicals and other materials will be received from the warehouse.
Materials will be intermittently supplied from warehouse to the drilling site, during
operations; a provision will be kept for temporary storage of materials at the drilling site
itself.
Rig Mobilization and Rigging up
A rig building process will follow the site preparation activities. This process involves
transport of rig including auxiliary equipment and camp facilities, assembling of various rig
parts and equipment to drill a well. The rig including auxiliary equipment and camp facilities
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 37 ONGC
will comprise of around 100 truck/trailer loads. Once the drilling rig is assembled, thorough
rig inspection will be carried out to check equipment working capability and quality
standards. The rig will have various allied equipment like mud tanks, mud pumps,
compressors, fuel tank, DG sets etc.
Initial Well Construction
Spudding in well is the start of drilling activity. Top-hole section will be drilled to a desired
depth based on well design. After drilling top-hole section, it will be annualated with a pipe
called “Casing”. Casing provides support to hole wall and secures hole section. Other than
that, it isolates problematic hole sections such as loss zones, shale sections, over pressurized
formations etc. After running casing, space between hole wall and “Casing” will be
cemented. This process of drilling and casing the hole section continues until the final well
depth (target) is achieved. Lengths and diameters of each section of the well are determined
prior to drilling and are dependent on the geological conditions through which the well is to
be drilled. Once each section of the well is completed, the drill string is lifted and protective
steel pipe or casing lowered into the well and cemented into place.
2.5.2 Drilling Activity
The exploitation of hydrocarbons requires the construction of a conduit between the surface
and the reservoir. This is achieved by the drilling process. Drilling operations will be carried
out using an electrical type drilling unit for drilling of oil and gas wells consist of a Derrick at
the top of which is mounted a crown block and a hoisting Block with a Hook. This rig will be
suitable for deep drilling up to the desired depth of 2800 m, as planned for the project.
Additionally, there will be other ancillary facilities like Drilling mud system, Effluent
Treatment Plant (ETP), Cuttings disposal, Drill Cementing equipment etc. and utilities to
supply Power (DG sets), water, fuel (HSD) to the drilling process and will be set up as a part
of the project.
Mud System and Cuttings
During drilling operations a fluid known as drilling fluid (or ‘mud’) is pumped through the
drill string down to the drilling bit and returns between the drill pipe–casing annulus up to
surface back into the circulation system after separation of drill cuttings /solids through solids
control equipment. Drilling fluid is essential to the operation and helps in controlling
downhole pressure, lift Soil/rock cuttings to the mud pit, prevent cuttings from settling in the
drill pipe, lubricate, cool and clean the drill bit amongst other functions.
It has been decided that an ecofriendly water-based mud system will be used in all the
proposed wells. Mud used during the operation will flush out formation cuttings from the
well hole. These cuttings will be separated from the drilling mud using a solids-control and
waste management package. Cuttings will then be stored in the HDPE lined pits (of
approximately 600 m3 capacity) and after completion of the drilling activities, cuttings will be
tested for hazardous nature and based on nature of the drill cuttings, final disposal pathway
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 38 ONGC
will be finalized as per CPCB Guidelines. The total amount of cuttings produced during the
entire drilling period is projected to be about 200 m3.
Once the cuttings have been separated, the drilling fluid will be reused or processed after
further treatment in a Chemically Enhanced Dewatering (CED) system designed to remove
suspended solids that are too fine for mechanical separation in solids control package
producing inlet particles called ‘flocs’. The flocs will be removed in the decanting centrifuges
and the resultant sludge disposed off in High Density Polyethylene (HDPE) lined pits. The
cleaned waste water will also be stored in HDPE lined pits and disposed off, after necessary
treatment and testing to meet the CPCB Discharge Guidelines.
The whole process by which the drilling fluid will be reused during drilling operation is
commonly known as a “closed loop system.” This system cuts down on the total water
consumption for the formulation of drilling mud and also saves on the consumption of
chemicals. Figure 2-11 shows the schematic layout of the drilling waste management.
Figure 2-12 shows the drilling fluid circulation system which is designed to enable the
drilling fluid to be recycled and maintained in good condition throughout the operation.
Various components of the drilling mud will be selected carefully to be able to provide
desired properties to the mud. Mud chemicals will be added to the uniform mud system to
adjust the mud properties and ensure fluid loss control/circulation, lubricity, shale inhibition,
pH control and pressure control in the well during drilling.
Additionally, some chemicals will also be stored in the drill site. The storage area will be
paved and bunded and will be provided with a shed.

Cementing Programme
Cementing is a necessary aspect of drilling oil and gas wells. Cement is used to
Secure/support casing strings
Isolate zones for production purposes
Solve various hole problems
Cementing generally utilizes Portland cement (API Class G Oil Well Cement) with various
additives in small quantities as accelerators/retarders, density adjusters, dispersants, fluid loss
additives, anti gas migration additives, etc.
Well Logging
Between the drilling operations for different zones, logging operations are undertaken to
provide information on the potential type and quantities of hydrocarbons present in the target
formations. Technicians employed by a specialist Logging Service will be entrusted with the
job of undertaking well logging. Logging instruments (sensors) will be attached to the bottom
of a wire line and lowered to the bottom of the well. They are then slowly brought back, the
devices reading different data as they pass each formation and recording it on graphs, which
can be interpreted by the geologist, geophysicist and drilling engineer. There are no
emissions to the environment associated with wire line logging operations. The radioactive
source required for well logging operations will be kept in specially designed container.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 41 ONGC
Hydrocarbons in the form of oil and/or gas are flowed during well testing operations. The
excess hydrocarbons are flared out through a burner located in a burn pit. The burn pit is 15
m in length and 8 m in breadth. The depth of the pit is around 4 to 5 m. It is usually located at
a distance of minimum 90 m away from the center of the well. The burn pit is constructed
with concrete and its walls are built from refractory bricks.
Oil produced at the time of well testing operations will be collected in an oil tanker and taken
to the nearest OCS
2.5.3 Well Decommissioning
Well Abandonment
On completion of activities, wells will be either plugged and suspended (if the well
evaluations indicate commercial quantities of hydrocarbons) or killed and permanently
abandoned. In the event of a decision to suspend the well, it will be filled with a brine
solution containing very small quantities of inhibitors to protect the well. The well will be
sealed with cement plugs and wellhead fittings (Blind Flange) left on the surface (Cellar). If
the well is abandoned, it will be sealed with a series of cement plugs, all the wellhead
equipment will be removed leaving the surface clear of any debris and site will be restored.
Site Closure and Decommissioning
After completion of the drilling activity, partial de-mobilisation of the drilling rig and
associated infrastructure will be initiated. As discussed earlier, well testing may be carried
out immediately after the drilling is completed or about 4 months depending on initial
evaluation timing. The complete de-mobilisation of the facilities at site will happen after
well-testing has been completed. This will involve the dismantling of the rig, all associated
equipments and the residential camp, and transporting it out of the project area. It is expected
that demobilization phase will last about 10 days and will involve the trucking away of
materials, equipments and other materials from site to bring it back to original condition. It is
estimated that about 100 truckloads will be transported out of site during this period.
Subsequently, following steps will be typically involved to restore and rehabilitate the area:
The wellhead and all casing string will be cut off to a minimum depth of 3 m (10 ft)
below ground level.
All concrete structures will be broken up, and the debris disposed off as per the
regulatory requirements.
All other waste products, solid and liquid, will be disposed of in accordance with the
requirements of the EIA and will be treated to render them harmless.
All fencing and access gates will be removed.
All pits whose contents will show regulatory compliance for on-site disposal, at the
time of site closure, will be backfilled and closed out as per the legal requirements.
Restoration of unusable portion of the access track, removal of pilings and
Landscaping.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 42 ONGC
Site Restoration
All abandoned drill sites will be restored back to its near original condition. After
decommissioning of site, it will be de-compacted and stored top soil will be overlaying on the
de-compacted site with certain moisture conservation measures for restoration soil nutrient
level naturally.
2.6 UTILITIES & RESOURCE REQUIREMENTS
2.6.1 Power Supply
The power requirements at the site preparation and construction phase for the drill site will be
met by 63KVADG Sets. Although drilling operations will be continuous, power requirement
will vary depending on activities being carried out. It is anticipated that two DG sets with
power rating of 1215 KVA each will be required for drilling purposes. One or Two units will
be in operation at a time depending on the load requirement and one unit will always be in
standby mode.
2.6.2 Water Consumption and Supply
Total water requirement/day for the drilling operation including domestic usage is estimated
to be about 25KLD. Out of 25 KLD, 8 KLD is estimated for rig operations, 15 KLD in mud
operations, while 2 KLD will be required for domestic usage. The total projected average
consumption of water during the drilling phase of 120 days will be about 3000 KL per well
including domestic purposes. Water will be sourced through the local available sources.
ONGC will take permission from Ground Water Authority regarding abstraction of ground
water for industrial purposes if required. The water requirement per well is shown in Table 2-
3.
TABLE 2-3: WATER REQUIREMENT PER WELL
A provision for storage of about 165 KL of water (5 days water requirement during peak
period) will be made on site. Potable water requirement at site will be met through filtered
bore well water and some packaged drinking water.
In addition, a water storage pit of around 1000 KL is proposed to store water for fire water
supply the likely source being ground water. The water balance diagram is provided at
Figure 2-13.

SENES 44 ONGC
2.6.3 Fuel Consumption
Fuel consumed during the drilling phase will mainly be diesel used for various equipment and
vehicles operating to transport goods and supplies to site. It is estimated that about 1 KL
diesel will be required to power the off-road construction equipment and vehicles during site
preparation phase.
During the drilling phase, consumption about 8 KLD of High Speed Diesel (HSD) will be
required. Fuel will be supplied onsite by local supplier through mobile tankers. Out of this, a
major part comprising about 85% will be consumed by the rig (also include the DG sets) and
about 15% will be required for the campsite. Fuel in excess approximately 56 KL (7 day’s
reserve) will be stored at onsite storage facility as per Petroleum Rules, 2002 in a paved and
bunded area.
2.6.4 Accommodation and Campsites
Sometimes it is necessary to provide camp facilities to operations staff, crew and other
contractor personnel. The campsite will provide accommodation to all operational crew and
the contractor personnel. At any point of time, it is anticipated that about 60 personnel per
shift will be housed in the campsite during the well drilling campaign. Toilet facilities will be
built in as part of the accommodation unit. The sewage lines from units will be connected
through a pipeline system to a septic tank and soak pit system constructed as per
requirements of local laws. Food and other organic waste will be subjected to bio-degradation
through organic composting.
2.6.5 Manpower / Employment
During the drilling phase, about 30 people will be working per shift. Total 2 shift of 12 hrs
will be operated during the drilling operations. Considering the two shift and 30 persons per
shift, total 60 persons will be present on the drilling site. This will include technical experts
(including expats), who will be responsible for various drilling related activities and some
local workmen who will be hired from nearby villages for the entire duration of the project.
Technical staff will be housed whenever required in the drilling camps which will be
adequately supported by facilities like kitchen, wash rooms, laundry, etc.
2.7 POLLUTION SOURCES AND CHARACTERIZATION
2.7.1 Noise and Vibrations
Noise will be emitted from drill site during site preparation, drilling and decommissioning
phases. The major noise generating operations from the proposed activity during drilling,
testing are operation of rotary drilling equipment as part of rig, diesel engines for power
generation, mud pumps and operation of vehicles. Noise during the site preparatory phase
will primarily be contributed by heavy construction machinery operating on site and
vehicular sources. Average noise emission ranges for different types of construction
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 45 ONGC
machinery and noise level of drilling rig and its equipment are shown in Table 2-4 and Table
2-5 respectively.
As drilling activity is continuous, part of the noise associated with functioning of the rig and
ancillaries will be generated throughout day and night.

2.7.2 Air Emissions
Air emissions from point sources expected from the proposed drilling activity will be mainly
from combustion of diesel in the diesel engines and power generators which will be operated
to meet power requirement of the drilling rig and the campsite. The principal pollutants will
comprise of Suspended Particulate Matter (SPM), Sulphur and Nitrogen dioxides (SO2 and
NO2) and other hydrocarbons (HC). The quantity of HSD consumed during drilling will be in
order of 8 KL /day/drilling site.
Additionally, the flaring and burning of oil during the testing of the well will also lead to the
release of some pollutants including un-burnt hydrocarbons to the atmosphere. Some fugitive
emissions of dust and air pollutants from vehicular exhaust will also happen during the
project lifecycle, mostly during the construction and decommissioning activities.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 46 ONGC
Additionally, there will be re-entrainment of dust from the approach road leading to the site
mainly during the dry season.
Analysis of natural gas generated contiguous field reveal that, it is mostly methane, ethane
and propane without the presence of hydrogen sulfide.
2.7.3 Liquid wastes
During the drilling operations, drilling wastewater generated (approximately 8 m3 per day) as
a result of rig wash and dewatering of spent mud, effluents from washing of drill cuttings,
floor washings, pump, seal leakages, spillages will comprise of chemical ingredients of
drilling fluid thereby rendering effluent to be polluted. The characteristics of drilling and
wash wastewater will be primarily dependent on type and composition of drilling fluid used
for drilling. As ONGC is proposing the use of water-based drilling mud, the potential for
contamination of such waste water is significantly lower. The drilling wastewater will contain
spent drilling fluid generated as a result of washings. The rig wash water and drilling
wastewater generated is proposed to be collected in a wastewater pit (of capacity 600 m3)
constructed at the drilling site. Domestic waste water generated (about 6.4KLD for the
drilling camp) will be treated through a soak pit/septic tank arrangement.
The quantities of the liquid wastes, their characteristics and anticipated disposal methods are
given in Table 2-6.

2.8 DRILLING HAZARDS
Loss of well control / blow-out, fire, explosion and oil spills are the major potential hazards
associated with drilling for oil and gas. Effective response plans to foreseeable emergencies
will be developed by ONGC and communicated to the project teams. A risk assessment to be
carried out as part of this EIA will also contribute towards identification of hazards, risks and
formulating management plans for emergency response, blowout, oil spills.
2.9 PROJECT COST
Based on ONGC’s previous experience of drilling in the area, cost for drilling 4
wells(including well site construction and site decommissioning) will be approximately INR
160 crores i.e. 40crores for each well. The cost of drilling will depend on the depth of the
well to be drilled.
2.10 HSE POLICY
ONGC is committed to protecting environment, health and safety of the people who may be
affected, directly or indirectly by its operations. The Drilling Management System (DMS)
framework lays down the corporate Health, Safety and Environment Policy for the entire

organization and the range of operations it undertakes as a part of oil and gas exploration.
The overall corporate health environmental safety policy of ONGC may be supplemented by
a local policy document whenever so required. It is understood that ONGC will try to
formulate a local site level policy taking from the parent corporate policy of ONGC to
adequately address the environmental impacts of the proposed drilling projects in VN-ONN-
2009/3 Block through the DMS. The Corporate Environment and Safety Policy of ONGC is

3 Description of the Environment
This chapter describes the existing environmental settings of VN-ONN-2009/3 Block and its
immediate surroundings. This includes physical environment comprising air, water and land
components, biological environment and socio-economic environment. Attributes of the
physical environment like air, water, soil and noise quality in the Block and surrounding area
were assessed primarily through monitoring and analysis of samples collected from the area.
Air, water, soil and noise primary monitoring was conducted by TUV SUD Laboratory (a
NABL certified laboratory). SENES personnel were responsible for selecting the monitoring
stations and supervision of onsite monitoring. Primary monitoring was conducted in winter
season (Jan-March), 2015.
Information on geology, hydrology, prevailing natural hazards like floods, earthquakes etc.
have been collected from literature reviews and authenticated information made available by
government departments. Primary surveys were carried out to understand and record the
biological environment prevailing in the area and the same was verified against published
information and literature. The socioeconomic environment has been studied through
consultations with various stakeholders within the VN-ONN-2009/3 Block. Additionally,
socioeconomic data have been obtained from the Census of India reports.
3.1 STUDY AREA
Area within the lead area identified by ONGC for exploration and other project activities has
been selected to carry out the primary environmental baseline monitoring, while the
secondary information was collected for entire block VN-ONN-2009/3. Since the block is
falling in two districts i.e. Damoh and Chhatarpur therefore secondary information have been
collected and analyzed for both the districts whereas primary data is limited to lead area
within the VN-ONN-2009/3block. While selecting locations for primary monitoring of air,
noise, water, soil and meteorology special emphasis is given to receptors present in lead area
because of operation of proposed project in lead area only. Monitoring stations for air and
noise were selected in proximity to the proposed well sites and access roads. Monitoring
locations for surface water quality was selected based on the macro and micro watershed and
drainage pattern of the area. Soil sample locations were selected based on the landuse-land
cover of the study area. Locations of ecological and social surveys were also selected based
on receptor locations; in addition, special emphasis is given to areas within 1 km radius of the
well sites and access roads.

3.2 PHYSICAL ENVIRONMENT
3.2.1 Climate & Meteorology
Climate and meteorology of a place can play important role in decision making for
implementation of any developmental project. Meteorology (weather and climate) plays a key
role in understanding local air quality as there is an essential relationship between
meteorology and atmospheric dispersion involving the wind speed/direction, stability class
and other factors. The climate of an area is largely defined by its terrain, altitude, range of
temperature variation etc. The VN-ONN-2009/3 Block falls under the humid climate zone.
Like most of north India it has a hot dry summer (April-June) followed by monsoon rains
(July-September) and a cool and relatively dry winter. The annual average rainfall is about
1,331 mm. Extreme temperatures are rare in Madhya Pradesh but still one can experience
every season here like summers with heat waves, winters with cold waves and monsoon with
heavy rainfall.
Seasons
The following are the well-defined seasons of the region:
Hot Dry summer : March-June
Monsoon : July- September
Post-monsoon : October- November
Winter : December- February
Meteorology data from the nearest IMD
station (150 kms from block) in Jabalpur
has been referred for analysis. Based on
the analysis of meteorological data of IMD
station at Jabalpur and data obtained from
the primary monitoring conducted at Hatta
town during Jan-Feb 2015 the temperature
profile, rainfall pattern relative humidity,
wind speed and wind direction of the
region have been discussed below and
shown in detail in Annex 3.
Temperature
Interpretation of IMD Station in Jabalpur
The temperature varies from place to place depending upon the altitude and other factors.
Winter sets on November and continues up to February. The coldest months are December
and January, but the degree of coldness varies from place to place due to variation of altitude.
The hottest months are April, May and June. During summer the maximum temperature goes
as high as 420c and during winter it drops to 100c. The average mean annual temperature of
Jabalpur districts headquarter is 29.60C.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 52 ONGC
Interpretation of Primary Baseline Data
During the study period the maximum temperature ranged between 26.2˚C to 37.5˚C and the
minimum temperature ranged from 21.2˚C to 28.7˚C.
Relative Humidity
Interpretation of Primary Baseline Data
The mean of daily maximum and minimum Relative Humidity (RH) was recorded as 97%
and 19% respectively during the primary monitoring study.
Rainfall
Interpretation of IMD Station in Jabalpur
The rainfall is quite high and is fairly well distributed throughout the year which encourages
growth of vegetation. Variation in rainfall from place to place is common within the Block
due to its varied topography and altitude. Most of the rainfall is received during monsoon.
Rains are received from south-west monsoon, predominantly. North-east monsoon also
contributes to winter season rain during January - February. The south-west monsoon starts
from June and continues up to September.
Interpretation of Primary Baseline Data
A total of 5.5 mm of rainfall was recorded during primary monitoring period. Five rainy days
were recorded. The hourly rainfall varied between 0.5 mm to 3.5 mm.
Wind Speed and Wind Direction
The wind speed and wind direction of an area influences the dispersal of pollutants from a
point and non-point sources. As the proposed drilling and testing activities involve the
operation of both point (DG sets) and non-point pollutant emissions sources, analysis of wind
speed and direction data is considered important for predicting the air quality impacts based
on pollutant dispersion.
Interpretation of IMD Station in Jabalpur
The prevailing winds are usually of low velocity i.e. 1.5-4.5 m/s. Predominant wind direction
is from west followed by south.
Interpretation of Primary Baseline Data
Hourly micro-meteorological data collected during primary monitoring has been analyzed to
generate the wind rose. The predominant wind direction was observed as South for the study
period. The average wind speed for the study period was 1.3 m/s. The wind in the study
period blew at a speed of 0.03m/s to 7.47 m/s. About 43.36% of Calm frequency was
recorded. This period recorded winds mostly between 2.1 to 3.6m/s.

3.2.2 Ambient Air Quality
Primary monitoring of the ambient air quality was undertaken in lead area of the proposed
block to establish existing ambient air quality of the area. Location of the proposed wells,
access routes to the well sites, predominant wind direction etc. are important in selection of
the ambient air quality sampling stations as any gaseous and particulate emissions from the
project activities will disperse based on the wind directions and affect the receptors located at
that end. Thus the analyzed values for the pre project environment can be compared during
and after the project activities.
Ambient air quality monitoring was conducted in winter season (Jan-Mar) of 2015. As per
the ToR eight ambient air quality locations are to be selected and monitored for ambient air
quality. The eight ambient air quality monitoring stations are selected keeping in mind the
pre-dominant wind direction in the area, location of receptors, and accessibility to the
monitoring locations and security concerns of machine and personnel. The number of
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 54 ONGC
monitoring stations and parameters (PM10, SO2, NO2, methane hydrocarbon, non-methane
hydrocarbon, VOC) for monitoring were based on the approved ToR obtained from MoEF.
However, in addition samples for PM 2.5were also analyzed in each monitoring station. The
ambient air quality locations are shown in Figure 3-6. The concentrations of various
pollutants were processed for different statistical parameters like arithmetic mean, minimum
concentration, maximum concentration and percentile values. A summary of ambient air
quality results is presented in Table 3-1 and shown in detail in Annex 4.
Interpretation of Air Quality Results
Particulate Matter (PM 10): The average of 24 hourly PM10 at the monitoring locations ranged
between 70-107.7μg/m3 (Figure 3.2). The 98 percentile PM10 values of the stations ranged
between 88-134μg/m3. The average as well as 98 percentile PM10 concentrations at many
monitoring sites were observed not to be in compliance to the NAAQS (100 μg/m3). The
reason for a slight exceed of PM10 at some places might be the farming activities, movement
of cattles, tractors etc. The statistical results of PM10 levels at the monitoring stations are
presented in Table 3.1.

Particulate Matter (PM2.5): The average of 24 hourly PM 2.5 at the monitoring locations ranged
between 32.5-42 μg/m3 (Figure 3.3). The average and 98% values for PM2.5concentrations
were observed to be in compliance to the NAAQS (60 μg/m3) at all air quality monitoring
locations. Lowest average value was recorded at Luhari while the highest value was recorded at
Hatta town. The statistical results of PM2.5 levels at the monitoring stations have been
represented in Table 3.1.
FIGURE 3-3: AVERAGE PM 2.5 VALUES AT THE MONITORING LOCATIONS
Nitrogen dioxide (NO2): The average NO2 values at the monitoring locations were observed in
the range of 20.6 to 25.9 μg/m3 (Refer Figure 3.4) while the 98 percentile values ranged
between 23.8 and 35.5 μg/m3. The average as well as the 98 percentile values complied with
the NAAQ standard(80 μg/m3) specified for nitrogen dioxide. Low values of NO2 can be
attributed to the primarily low vehicular density and less consumption of petroleum fuel as well
as no industrial activities, within the Block and its immediate surroundings. The concentration
values of nitrogen oxide representative of each sampling station have been provided in Table

Sulfur dioxide (SO2): Average values of sulphur dioxide concentrations ranges between 11.3
and 15.8μg/m3while the 98 percentile values ranged between 14 and 21.1 μg/m3. A lowest
sulphur dioxide concentration was recorded at Chakarda mafi village (AQ 5) and highest in
Hatta town.The concentration of Sulphur dioxide was found well within the NAQQS standards.
Methane and Non- Methane Hydrocarbon: The values for methane hydrocarbons at the
sampling stations varied between 0.1 and 1.1PPM. The methane concentrations were “Below
the Detectable Limits” (BDL) at 3 locations. The Detection Limit (DL) is 0.01 PPM. Values of
non-methane hydrocarbon were varied between 0.05 and 0.4 PPM. The concentrations were
found BDL at 6 locations. The DL limit is 0.01 PPM. Low values non-methane hydrocarbon
can be attributed to the negligible consumption of petroleum fuel and industrial activities within
the Block whereas low concentration of methane hydrocarbon is due to absence of wetland and
paddy cultivation in the area.
Total Volatile Organic Carbon (TVOCs): Values of VOC at all the monitoring stations are
below detectable limit (DL is 5 μg/m3). The concentration values of methane, non-methane
hydrocarbon and Total VOC representative of each sampling station have been also provided

3.2.3 Ambient Noise Quality
The ambient noise monitoring was conducted at 8 locations within the block area. Noise
stations were selected near to the proposed well locations and access roads to understand the
baseline noise levels that could be impacted upon by the proposed drilling activities at the
Block. Sound pressure level (SPL) measurements in dB (A) were recorded for every hour
continuously for 24 hours at 15 minutes interval for the monitoring stations1 and equivalent
noise levels in the form of Leq day and Leq night was computed. The results obtained were
compared with the standard specified in Noise Pollution (Regulation and Control), Rules
2000, (as amended). Detailed Noise monitoring results are shown in Annex 5.
Interpretation of Noise Quality Results
The day time and night time equivalent noise levels varied between 50.5 -58.6 dBA and 42.4-
45.3 dBA respectively. The day time equivalent noise levels at Hatta town had the highest
values whereas Motha village had the lowest amongst all stations. The national standards for
noise level in the residential areas during day time is 55 dBA (Please refer Figure 3-5).The
night time equivalent noise levels for all the monitoring stations were found to be in
compliance to the night time noise standards (45 dBA) prescribed for residential area except
at Hatta Town where night time noise level was marginally high (45.3 dBA).

3.2.4 Topography &Geology
Topography of Block
The VN-ONN-2009/3 block is located in Damoh and Chhatarpur Districts. The region has a
slope towards northwest. Topography the block is mostly flat with slightly undulations in
north region of the block. The elevation ranges from 348 meters to 499 meters towards in the
northern portion of the area. It reduces the elevation around 343 meters towards south east
direction where Vindhyan form escarpments. The area is lies in between the two plateau and
the clearly cut escarpment. The project area lies in the catchment area of river Ken, which
falls in the Ganga Basin. The major drainage within the block consists of Sonar River and its
tributaries such as Kopra River and Baink river. Sonar River is itself tributary of Ken River
and passes through the block. The flow of drainage within the area is towards north east and
north and thedrainage pattern is almost dendritic. (Source: Central Ground Water Board)
Regional Geology
The block is situated in the north western part of the Son Valley, a sub basin of Vindhyan
basin. Vindhyan basin is found by Great Boundary Fault (GBF) to the west to northwest.
Towards its south, this basin is bounded by southwest to north east trending Son Narmada
Lineament. Bundelkhand Massif separates the Vindhyan basin into two structural provinces;
western known as Chambal Valley and eastern known as Son Valley.
Stratigraphy of the area
The entire Vindhyan succession is having maximum thickness of 3 km and comprises mainly
sandstone, shale and limestone is assigned as the Vindhyan Supergroup. This supergroup is
further categorized into four subgroups as given in Table 3-2:

3.2.5 Hydrogeology
The geological formation in the study area represents alluvium and deccan trap formation.
Alluvium formation consists of soft rock whereas deccan trap, lametas and vindhyans
formation indicates presence of hard rock. As mentioned in section 3.2.4, block VN-ONN-
2009/3 comes in vindhyan super group and consists of hard rock with unconfined aquifers.
The aquifer consists of sandstone, shale and limestone. The depth of ground water in the
proposed block varies from 5 to 20 m bgl in pre-monsoon season. During the post monsoon
season ground water level in the study area varies from 2 m -20 m bgl. Ground water level
map of the study area is shown in Figure 3-8 & Figure 3-9 (Source: District Groundwater
Booklet, Chhatarpur District, 2006).
Ground Water Resources
An annual replenishable ground water resource in Chhatarpur District is 948.41MCM. Net annual
ground water draft of the district is 536.10MCM.
3.2.6 Drainage
The study area falls in the catchment of Ken River. However, Ken River does not flow
through the block. Sonar Nadi, a tributary of Ken River flows through the block area.
Drainage system in the block, comprises by Kopra River, Baink River and various seasonal
drains. Kopra River is the nearest drainage channel to the well location R-HAT-C. The major
drainage channel within the block in Damoh district is Sonar River which flows from south
west to north east and drains into the Ken River outside the block area. The drainage map of
the study area is presented in Figure 3-10.

3.2.7 Ground Water Quality
Primary source of potable water in the area is ground water. Hatta town is having piped water
facility which is abstracted from groundwater and stored in overhead tanks for supply. In
addition to that groundwater is also abstracted by dug well and tube well; however, same is
abstracted by a very limited number of dwellers. Primary monitoring of potable water quality
was considered important in order to understand the probable impacts of the proposed project
activities on the water used by the locals for drinking and other purposes. Potential pollution
of subsurface and unconfined aquifers may occur due to improper casing and cementing of
well leading to infiltration or seeping of drilling chemicals or mud into nearby aquifer.
Contamination of aquifers may also occur from disposal of drilling waste and mud in an
open/unpaved pit.
A monitoring network consisting of 5locations for potable water was selected and
representative sampling was carried out at each of the locations (Refer Figure 3-10) and the
detailed results of potable water analysis are presented in Table 3-3.
Ground Water Sampling Points
A total of 5nos. potable water samples collected from settlements within the Block and its
surrounding for analysis. Samples were analyzed for physicochemical and bacteriological
parameters and results compared with IS: 10500 drinking water standards to identify and
interpret any deviation in the statutory limits set for parameters under this standard.
Interpretation of Ground Water Quality Results
Primary monitoring of potable water quality was considered important in order to understand
the probable impacts of the proposed project activities viz. discharge of wastewater to
streamsor leakage of drilling mud and chemicals to the sub surface aquifer water used by the
locals as source for drinking and other purpose. Potential pollution of subsurface and
unconfined aquifers may occur due to improper casing and cementing of well leading to
infiltration or seeping of drilling chemicals or mud into nearby aquifer. The drilling activities
and discharge of wastewater, drilling mud of the drill sites may pollute the source of potable
water used by the locals. Contamination of aquifers may also occur from disposal of drilling
waste and mud in an open/unpaved pit.
A monitoring network consisting of 5 locations for ground water was selected and
representative sampling was carried out at each of the locations (Refer Figure 3-11) and the
detailed results of analysis are presented in Table 3-3.
Ground Water Sampling Points
A total of 5 nos. ground water samples were collected from dug well and deep tube wells.
Samples were taken from Majhguwan Patol, Hatta town, Luhari village, Ghurata village and
Haruda Jamsa village. Samples were analyzed for physicochemical and bacteriological

ONGC
parameters and results compared with IS: 10500 drinking water standards to identify and
interpret any deviation in the statutory limits set for parameters under this standard.
Interpretation of Potable Water Quality Results
Turbidity
Turbidity values in all sampled water found <1.0 NTU which shows that all the drinking
water sources ( mostly tube wells) meet the acceptable limits as per IS:10500.
Chlorides and Total Dissolved Solids
With respect to IS:10500 standards, acceptable limit of chloride is 250 mg/l while the
permissible limit of the said parameter (in absence of alternate source) is 1000 mg/l. At
concentration above 250 mg/l chlorides renders a salty taste to water.
The chloride concentration in the potable water samples of the study area villages have been
found to be well within the acceptable limits ranging from 29.2 mg/l (at GW 4- Ghurata
village) to maximum of 236 mg/l ( at Majhguwan Patol village).
The concentration of total dissolved solids (TDS) in potable water is a measure of its
suitability for domestic use. TDS values at 500 mg/l or below is considered to be acceptable
for drinking being specified under IS:10500 drinking water standard. The TDS values for the
potable water samples analyzed found in the range of 594 mg/l (at GW4 Ghurata) 1346 mg/l
(at GW 1 Majhguwan Patol). TDS concentration in all the sample exceeds the acceptable
limits but well within the permissible limits.
Total Hardness
Hardness of water is considered to be an important parameter in determining the suitability of
water for domestic uses particularly washing. Hardness of water is correlated to the presence
of bivalent metallic ions viz. calcium and magnesium. Total hardness values for the potable
water samples analyzed is in the range of 66 mg/l (at GW 2, Hatta Town) to 740 mg/l
(Majhguwan Patol village) and were found to exceed the acceptable limit at all location
except at Hatta Town. However, value is within the permissible limits at all the locations.
Further as discussed above, the hardness values recorded at each potable water monitoring
station was found to be in correlation with the calcium and magnesium ions analyzed for such
samples. The concentration of calcium and magnesium ions was found to be within
acceptable limits specified for the aforesaid parameters as per IS:10500 standards.
Iron and Fluoride
Iron is considered to be an important potable water parameter since at higher concentration it
interferes with laundering operations and imparts objectionable stains. Iron concentration of
potable water samples collected from Ghurata village (0.42 mg/l) exceeded the acceptable
limit i.e. 0.3 mg/l as per drinking water standard. Rest of the samples were found to be well
within the acceptable limits. High iron content recorded in groundwater from Ghurata village
may be probably due to local geological features. Fluoride contents in the potable water

SENES 70
ONGC
samples were found to be within the permissible limits, although the sample collected from
Hatta town exceeds the acceptable limits.
Heavy Metals:
The monitoring results showed that the concentration of heavy metals (chromium, copper,
zinc, mercury, cadmium. lead, nickel, arsenic etc.) is within acceptable limit as per IS: 10500
standards.
Coliform
Coliform are indicators of contamination from sewage and faecal matter. Coliform were
found to be less than 2 MPN/100 ml in all the samples. Total coliforms comprise bacterial
species of fecal origin as well as other bacterial groups commonly occurring in soil. The
coliforms are indicative of general hygienic quality of the water and potential risk of
infectious diseases from water.
Sources of Total and Fecal Coliform in groundwater can include: (1) Agricultural runoff; (2)
Effluent from septic systems or sewage discharges and (3) Infiltration of domestic or wild
animal fecal matter. Poor maintenance and construction (particularly shallow dug wells) can
also increase the risk of bacteria and other harmful organisms getting into a well water
supply.

3.2.8 Surface water quality
Primary monitoring of surface water quality was given importance during scoping of the EIA
study as the effluent generated during the exploratory and appraisal well drilling operations
are likely to be discharged to nearby surface water bodies/natural drainage channels/rivers
after ensuring that it meets prescribed norms of CPCB.
Surface water samples were collected from five surface water sampling locations. Location of
proposed wells, micro ¯o- water shed as well as surface water channel those are likely
to be impacted from the discharge that may occur from proposed well sites. The well site R-
HAT-C is located within the micro-watershed of Kopra River therefore sample from Kopra
river has also been taken in addition to Sonar River for analysis. Kopra River is tributary of
Sonar River and it merges with the Sonar River near Pipariya village.
Water sampling and analysis2 was done following CPCB standard guidelines for physical,
chemical and bacteriological parameters. The monitoring locations are shown in Figure 3-11.
Surface Water Sampling Points
Surface water samples were collected from all major water channels of the study area i.e.
upstream and downstream of Sonar River , Kopra river near Piparia, Confluence of Sonar and
Kopra at Pipariya and Sonar River at Sitanagar to get an overview of the surface water
quality of the study area. Surface water quality was finally assessed against water quality
criteria as per CPCB guidelines for water resources. Results of surface water samples have
been discussed below.
Interpretation of Surface Water Quality Results
The pH of all analyzed surface water samples found to be slightly alkaline in nature and
varied from 7.24 to 7.42. The temperature of water samples was recorded at the time of
sampling was between 180 and 190 C. The dissolved solids content varied between 274 to 344
mg/l while the electrical conductivity varied from 411-500 μS/cm. from SW3 (downstream of
Sonar River near Hatta town) while rest of the samples were found to be <5 mg/l.
The DO levels exhibited values ranging from 3 to 6.1 mg/l indicating favorable conditions for
the growth and reproduction of normal population of fish and other aquatic organisms in
upstream of Sonar River. As the surface water sources are not used by the locals for drinking
purposes and mostly the river/stream water exclusively is being used for irrigation purposes,
the water quality is compared with the CPCB prescribed water quality criteria- Class- E
(Irrigation, Industrial Cooling, Controlled waste disposal). Class- E does not have any criteria
for DO or BOD. The DO level from all the stations even meet the standard of Class-C (
Drinking water source after conventional treatment and disinfection). The CPCB water
quality criteria for designated best use classes have been shon in Annex 6.

BOD values in all the surface water samples were ranged between 2.8 mg/l and 12 mg/l. The
maximum value (12 mg/l) recorded from SW3 (downstream of Sonar River at Hatta Town).
Sodium Absorption Ratio varied between 0.4and 0.61. Free ammonia content ranged between
<0.5 and 1.6 mg/l., whereas boron contents of all the samples were found to be less than 0.1
mg/l.
The total Coliform was varied between 23 MPN/100 ml to 1600 MPN/100 ml. Although
there is no standard for total coliform for class- E category, but the standard of coliform for
Class-C category water is 5000 MPN/100ml. The presence of oil and grease content in all
surface water sources was found to be negligible (between <0.5 and 0.62 mg/l). Heavy metal
concentrations such as Mercury ( <0.001mg/l in all samples), Lead (<0.005 mg/l in all
samples), Hexavalent Chromium( <0.03 mg/l in all samples), Copper (<0.05 mg/l in all
samples) and Nickel ( <0.005 mg/l in all samples) found to be negligible and well below the
WHO guideline values.
Detailed surface water analysis results have been provided at Table 3-4. After analysis it is
found that surface water is suitable for irrigation purpose.

3.2.9 Land-Use and Land Cover
The land-use and land-cover of the Block has been interpreted from the, toposheet of the
area, and subsequently by ground truthing during field surveys. The study area land use
shows that majority of the land within the Block (62.72%) is agricultural land. Rivers and
drains comprise of 2.28 % of the total Block area. Forest areas are near 31.8 % of the total
Block area. however, all the forest area is outside of lead area. Settlements comprise of 1.82
% of the total Block area. Road network including State Highway and other small roads
comprise of 0.05 % of the total Block.
The percentage distribution land use categories have been shown in Figure 3-12 and the land
use map is presented in Figure 3-13.

3.2.10 Soil Quality
To find out the soil texure and availability of nutrients in the soil, soil samples were collected
from the block area, during winter season. Soil sampling locations along with type of area
and detailed analysis results depicting physico-chemical characteristics of soil in
representative locations within the study area are given in Tables 3-5.
TABLE 3-5 SOIL SAMPLING LOCATIONS
Station Code Sampling Location Type of Area
S -1 Majhguwan Patol Agricultural land
S – 2 Luharil Agricultural land
S – 3 Khachna Naka, Hatta Town Agricultural land
S – 4 Ghurata Agricultural land
S- 5 Hurdua Jamsa Agricultural land
Map showing soil sampling locations within the block is given in Figure 3-11.
Interpretation of soil sample analysis
From the texture point of view, the soil from 4 locations out of 5, are found to be clayey in
nature, having good capacity for adsorption and retention of water and plant nutrients.
Therefore, it is suitable for agriculture and plantation. The soil sampled from Ghurata village
(S-4) shows that the soil has more silt than clay and the texture of the soil is silty clay loam in
nature.
The pH value of the sampled soil was found in between 7.73 and 8.14. It shows that the soil
is alkaline in nature. The pH of soil is directly related to plant growth, because soil acidity or
alkalinity directly affects plant growth. Electrical conductivity is used to estimate the soluble
salt concentration in soil, and is commonly used as a measure of salinity. The EC value for
soil ranges from 258 to 378 micro-siemens/cm. The soil samples revealed moderate available
nitrogen content (111.8 to 406 mg/kg). Heavy metals viz. iron, copper, zinc and manganese
are important soil micronutrients being considered essential for the normal growth of plants.
Deficiencies of micronutrient drastically affect the plant growth and metabolism. Iron varies
from 28801.4 to 41484.5 mg/kg., whereas the concentrations of copper ranges from 27.1 to
33 mg/kg; zinc ranges from 38.6 to 50.3 mg/kg and manganese ranges from 306 to 913.7
mg/kg. The sodium hazard of soil usually is expressed as the Sodium Adsorption Ratio
(SAR). The SAR value in the soil samples range from 1.8 to 3.4. Soil with high levels of
exchangeable sodium may cause dispersion of soil particles leading to the replacement of
major cations (calcium and magnesium) adsorbed on the soil. This could possibly lead to
deterioration of soil structures and water infiltration problems. The detailed soil analysis
results have been provided at Table 3-6.

3.2.12 Natural Hazards
A natural disaster during the life cycle of the
project can have a significant effect on the
functioning of the project in addition to
affecting the local environment in the area and
stressing the availability of resources for the
project. Such disasters also sometimes create
difficulties in access through disruption of
transportation links.
Seismicity & Earthquakes
The study area is located in Zone III as shown in
the Bureau of Indian Standards (BIS) 2000
seismic zone map for India (refer Figure 3-14).
Zone III is defined as region which might
encounter earthquakes of intensity VII (MSK).
Earthquake on 02nd June 1927 in Umaria area was the largest earthquake of in Madhya
Pradesh. The magnitude was recorded as 6.4. it was deep seated event and was felt at
Allahabad in Uttar Pradesh.

Floods &Flash Flood
Floods are common in Damoh and Chhatarpur district because of basin of major rivers such
as Ken and Sonar river. On 5th July 2005, Damoh, Chhatarpur and other districts of north
eastern part of Madhya Pradesh were badly affected by flash floods triggered by heavy rains
[source: infochangedisaster www.infochangeindia.org]. Due to heavy rain, all the major rivers
including Ken and Sonar were overflowing. As reported by the villagers residing near the
Kopra river, settlements near the river and various seasonal drains got affected by water
logging. The main causes of flash floods in the area are:
Obstruction in drainage system due to heavy rainfall
Increase in siltation in riverbeds due to erosion in the catchment areas.
Change of river course because of poor natural drainage system.
Risk of flash flood is associated with heavy rainfall particularly in the monsoon months (from
June to September).
3.3 BIOLOGICAL ENVIRONMENT
The primary objectives of the biological environment study are:
To assess the vegetation types
To identify common flora & fauna in the study area
To find out rare and endangered floral and faunal species
To evaluate wildlife habitat of the area and assess impact of the proposed project on
wildlife & their habitats.
To assess impact of the proposed project on agriculture and domestic livestock.
The ecological survey has been done to establish the baseline biological environment
conditions of the study area (area within the proposed block), which will enable us to identify,
predict and analyze the potential negative impacts on the local ecological condition from the
proposed project. And further, to develop adequate and feasible mitigation measures (via inputs
to project design and layout, working practices, or compensate where appropriate) to keep
residual ecological impacts with acceptable limits, and also to develop ecological monitoring
and audit.
3.3.1 Methodology
Desktop Review and Reconnaissance visit and Primary Survey
A desktop review (forest working plan and other published document etc.) was conducted to
determine the forest area (Toposheet and Satellite imagery), vegetation type (Champion and
Seth, 1962), floral and faunal assemblage in the study area. A site reconnaissance visit and
primary survey was conducted to identify different ecological habitats, sensitive ecological
habitat and also to identify the targeted study area for baseline survey.

SENES 86
ONGC
3.3.2 Habitat assessment
The information of prevailing baseline in project site is important because project related
activities might lead to loss of the ecological resources, if existing.
The proposed project site in M.P state lies within the biogeographic province-6A, Deccan
Peninsula- Central Highlands, (Rodgers, Panwar & Mathur, 2002).The biogeographic
province map is shown in Figure 3-14.
There are total five Reserved Forests (RF) such as Shahpura RF, Bhensdo RF, Sakari RF,
Chopara RF, Karkuhi RF and one Protected Forest (PF) Ghorakuhi P.F located within the
allotted block area (1250 sq km). As it is mentioned earlier that, it is proposed to explore the
oil potential at one location (R-Hat-A) besides other 3 oil well proposed to be drilled. It is
noteworthy, to mention no forest area fall within the 10 km radius of the any of the proposed
drill locations. The distance of all the forested areas is located between 18 to 20 km (aerial
distance) from the proposed drilling site. Nauradehi Wildlife Sanctuary is located at 42 km
from the proposed oil well. The other protected areas namely Ken Gharial WLS, Panna
(Gangau) WLS and Veerangna WLS are located at distances of 58 km, 43 km and 54 km
respectively. The protected map of Madhya Pradesh is shown in Figure 3-15.
FIGURE 3-15 MAP SHOWING BIOGEOGRAPHIC PROVINCES OF INDIA
The overall habitat in Project area is generally degraded. Good quality habitat is confined to a
few patches of the Reserved Forest areas only. The Settlements are located in and around the
Reserved Forests and as a normal practice, dependence on forest produce such as
grass/sedges, fuel wood from these forests are being used by the local villagers. Human

pressure such as cattle grazing, forest fires and fuel wood collection are the major reasons for
the degradation/fragmentation of wildlife habitats in these forest areas. The working plan of
Damoh Forest division has also mentioned on the rampant cattle grazing, forest fire,
dependence of its timber as well as fuel wood by the local villagers as the major reasons for
the degraded/depleted forests.
FIGURE 3-16 MAP SHOWING THE PAS OF MADHYA PRADESH
3.3.3 Terrestrial Ecosystem
Forest types
The forest type of this region is mainly 5A/C3- Southern Tropical Dry Deciduous Forest and
mostly dominated by teak. During the primary survey and as per the working plan of Damoh
Forest Division, the most of the vegetation of these forests are found to be mixed type.
During the floristic survey in and around the project area, efforts were limited to identify the
vascular plants.
Most of the RFs and PF of this block are found to be open mixed type of forests. Sakari RF
was found to be dense mixed and Shahpura and Karkuhi RFs were found to be fairly dense

Non-Forest Vegetation
According to the Forest Survey of India, non-forest area includes all area outside the
traditional/notified reserve and protected area. Trees available in the non-forest area is
classified into eight categories for the purpose of data processing and analysis, which are
farm forest, roadside plantation, village woodlot, block plantation, pond side plantation,
railway side plantation, canal side plantation and others which do not fall in any of the above
categories. Tree species in these sites are mostly planted and few are natural. The proposed
exploration block area exhibits presence of the following type of nonforest vegetation:
Farm Forest
Trees along farm bunds and small patches of homestead land at various villages are noticed.
Few dominant species recorded along the farm bunds are Neem (Azadirachta indica), Sissoo

grass.were recorded in forest areas, wasteland and non-cultivated land. These act as suitable
habitats for avifauna and hideout for small carnivores. The herbaceous and grasses also
attract the cattle of this areas for rampant grazing.
Village Woodlot
Village woodlots are naturally or planted trees on community or private land. Planted trees
recorded in village woodlot are Eucalyptus sp Mango (Mangifera indica), Sissoo (Dalbergia
sissoo), Mahua (Madhua indica), Ficus religiosa ( Pipal), Neem (Azadirachta indica), Bakain
(Melia azaderach), Imli (Tamarinda indica), Bamboo sp etc. These trees provide fruits,
timbers and source of income to locals.
FIGURE 3-17 A VILLAGE WOODLOT
Road side plantation
Trees are noticed along village road and state highway connecting to the site. Thick lustrous
leaves with dense canopy leaning over the road were commonly noticed. These trees provide
foraging, nesting and movement corridor for birds and small mammals. Higher frequency of
Mahua (Madhua indica), Aam (Mangifera indica), Shisham (Dalbergia sissoo), Neem
(Azadirachta indica), Kala sirish (Albizzia lebback), Bakain (Melia azaderach), etc. are
recorded.
3.3.4 Regional ecological resources utilization analysis
The principal crops are Rice, Wheat, Jowar and some varieties of coarse millet. Villagers
mostly depend on surrounding open scattered scrubs and other forested areas to meet their
fuel wood and fodder need. They have also grown multipurpose trees species such as Acacia
nilotica, Acacia leucophloea, Saccharum spontaneum (kaans), Heteropogon contortus
(kusul), Themeda quadrivalvis ( gunher), Aristida setaceae ( jhani), Cynodon dactylon (
doob), Eragrostis sp, Erianthus munja ( munj), Pennisetum hohenackeri ( moya),to meet

fodder for goat and sheep and fuel wood demand. From the grass species such as
Thysanolaena maxima ( phool bahari), Desmostachya bipinnata ( kush), Vetivania
zizanioides ( khas), Arundo donax, Eulaliopsis binate ( sabai), the villagers are getting
maximum benefit from its economic values.
Excessive removal of grasses, sedges, and herbs/shrubs is common in the area. Rampant
gazing and browsing was observed in entire study area The major reason for the rampant
grazing in those areas is the shrinking of pasturelands in the village common lands due to
changed land-use pattern. As far as collection and uses of the medicinal plants are concerned,
the locals do not practice any kind of traditional system of health care.

Fauna
A walk through survey was carried out in the study area to have idea about the faunal
distribution in the project site and its vicinity to the site. Besides, dialogues with the local
villagers and forest officials were also made to know the presence and movement of animals
in the forested areas as well as if at all any animal sneaks into village/settlements in search of
food/prey.
Mammals
During the primary survey, species such as Common Langur, Rhesus macaque, Jackal,
Common Mongoose were sighted around the forested areas. The herbivores such as Nilgai
were also recorded during this survey. Dialogue with the local villagers and forest officials
had confirmed the presence of striped hyeana, Common Indian Porcupine, Common Indian
hare, wild boar in these forested areas.
Avifauna
The mostly common bird species found in the block area are given in Table 3-9. No rare or
endangered bird species is reported to occur in the study area.

Reptiles
Garden lizards and gecko were found within the extensive growth of bushes. Table 3-10
gives list of reptiles recorded from the field survey and secondary information. Although no
information on the reptiles are described in the Forest Working Plan, but dialogue with the
local villagers do confirm the presence of poisonous , non-poisonous snakes and other
reptilian species in this region. These include the cobra, common Krait, Russell’s viper ,
monitor lizard.
The agriculture field in the study area provides an ideal habitat for many snakes and other
reptiles.

3.3.5 Aquatic Ecosystem
Sonar river flows at a distance of 1 km away from the proposed explored oil wells and it is
the only perennial water body in the study area. Sonar river is considered to be the largest
tributary of ken river. Ken has an overall drainage basin of 28,058 km2, out of which
12,620 km2 belong to Sonar River. Ken River is one of the major rivers of
the Bundelkhand region of central India, and flows through two states, Madhya
Pradeshand Uttar Pradesh. It is a tributary of the Yamuna. Sonar River has many tributaries
namely Kopra, Beamra, Bewas, Dehar, Kaith and Baink. Kopra is a seasonal stream also
flows within the oil block as well as near to the proposed oil wells.
Agricultural practices were observed all along the oil block and availability of water from
Sonar and Kopra River provides ample opportunity for the local farming communities to
cultivate varieties of crops.

FIGURE 3-19 RIVER AND FARMING ACTIVITIES ON THE RIVER BANKS
Sonar River Kopra River
Tree species such Ficus religiosa, Ficus benghalensis, Dalbergia sissoo, Syzigium cumini,
Acacia nilotica, and Bamboo etc were recorded in scattered fashion along the banks of Sonar
River. Scrubs/bushes of Saccharum spontaneum (Kaans), Themeda guadrivalvis (Gunher),
Aristida setaceae(Jhani), Erianthus munja (Munj), Thysanolaena maxima ( Phool bahari),
Desmostachya bipinnata (Kush), were noticed along the banks and river bed area.
Availability of water and scrubs/bushes habits are considered to be suitable habitat for small
wild animals and avifauna. Birds species such as Little cormorant, Common King fisher,
Pond Heron, Little Egret, Pied Myna were recorded from the river site. Fishing on Sonar
River is not practiced by the locals and information on fishery resources of Sonar River could
not be established.
Lentic and seasonal water bodies like manmade ponds were noticed near and within villages.
These ponds are rainfed and many of these dry up in summer season. Very few of them are
perennial in nature.
Phytosoiological Analysis
To analyse the phytosociological significance of the study area, the survey was carried
randomly in 4 Reserved Forest areas of the allotted block. The Reserved Forest chosen for
primary survey and analysis were Barikanoria RF, Karkuhi RF, Sakari RF and Chopra RF.
The phyto-sociological analysis was conducted for tree species only.
The major tree species recorded from these forests were Lagerstroemia parviflora, Mitragyna
parviflora, Disopyros melanoxylon, Acacia catechu, Pterocarpus marsupium, Aegle
marmelos, Butea monosperma, Madhuca indica, Holarrhena antidysentrica, Feronia
limonia, Terminalia tomentosa etc.
The vegetational composition from Karkuhi RF was found to be more diverse in comparison
to the other Reserved Forests where primary survey was conducted. To enumerate the
Important Value Index (IVI) of the exclusive tree species recorded from these forest areas,
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 94
ONGC
Relative Frequency; Relative Abundance; Relative Density were calculated. The results from
the analysis from each of the RF are presented in Annexure-11.
From the analysis, it is found that, Lagerstroemia parviflora has the highest IVI index in
Barikanoria RF with 44.38 followed by Acacia catechu 39.72, Feronia limonia 39.08 and
Manduca indica with 23.24. The IVI from Sakari RF enumerated as Lagerstroemia
parviflora 39.77 followed by Acacia catechu with 32.83, Holarrhena antydystentrica 30.01
and Madhuca indica with 29.09. The diversity of Madhuca indica was found to be the
highest in Kankuhi RF and the IVI of Madhuca indica was enumerated as 30.4 followed by
Acacia catechu 23.5 and Lagerstroemia parviflora 21.5.
The IVI of Madhuca indica from Chopra RF was recorded highest with 32.6 followed by
Lagerstroemia parviflora 29.8, Butea monosperma and Acacia catechu with 26 each and
Diospyros melanoxylon with 22.3.
From the analysis it was drawn that Lagerstroemia parviflora, Madhuca indica and Acacia
catechu are the important/valuable tree species of these forest areas.
The Shannon-Wiener Index (H) provides the status of how evenly the species are distributed
as wells as it gives clear picture of the abundance of the species in a particular community.
The higher “H” values states the more diverse communities. From the above analysis from 4
different forest areas, the value of “H” ranges between 2.62 (from Barikanoria RF) to 2.96
(Kankuhi RF) indicating that the diversity of Kankuhi RF has highest values in comparison to
others. Being falling under Southern Tropical Dry Deciduous Forest, these forested areas are
normally well diversified.

3.4 SOCIOECONOMIC ENVIRONMENT
This section discusses the baseline socio-economic environment of the ONGC’s block VN-
ONN-2009/3 located in Damoh and Chhatarpur district of Madhya Pradesh for proposed
exploratory well drilling operations. The following section discusses the methodology used for
the socio-economic assessment. The subsequent sections discuss the baseline profile of the
district and the villages within the proposed block.
3.4.1 Methodology
A socio economic assessment of the positive and negative impacts on the people likely to be
directly and indirectly affected by the project is conducted during the EIA study. The assessment
facilitated an understanding of the needs, demands, preferences, capacities and constraints of the
people in the vicinity of the project operation. It was undertaken primarily to enhance the
understanding of other relevant factors such as social organizations and networks, livelihood
patterns, social infrastructure, needs etc. and thus helped prioritizing ONGC’s commitment
towards the CSR initiatives. Inputs from the social assessment into the design phase facilitated
in:
Tracking potential adverse effects over different time frames and different
phases/activities
Reviewing options to eliminate such negative impacts through design changes or mitigate
them through specific social protection or mitigation measures
Reviewing options to extend or enhance benefits to the population in the vicinity of the
project site.
Focused group discussion with the community was conducted in the villages nearest to the
proposed wells (within a 2 km radius). Further, some more villages have also been visited for the
community discussion. Census 2011 data has been depicted and presented in the section below.
The census and secondary data has been cross checked during field/public consultations.
Primary data mainly through interviews with individuals and communities in the identified
villages (as per the preliminary project boundary) and secondary data such as published and
unpublished reports of the central and state government, information in the public domain was
collected.
3.4.2 General Socioeconomic Profile – based on Secondary data
The area within block has been identified for profiling of socio-economic environment of
villages located in Damoh and partially in Chhatarpur district, Madhya Pradesh. Identification of
the study area is primarily based on reconnaissance surveys, understanding of the project and

Community Consultation
A community consultation was carried out in 12 villages out of the 68 identified study area within
a block, for collecting detailed information about prevailing socio-economic condition in the study
area, demographic features and composition of the population, infrastructure amenities available in
the villages and also to assess awareness, opinion and reaction of the inhabitants about the project.
The key findings observed Community Consultation:
During consultations some key similarities observed in the villages where consultation were
undertaken with the villagers which are a reflection of the overall scenario of the villages within
the affected project area.
Occupation and livelihood is centered on rain fed agriculture and related labour work. Irrigation
facilities are largely not available and few farmers have access to bore wells for irrigation. In
almost all villages people reported out migration from the village seasonally or permanently due to
lack of livelihood. Most of these people return during harvest. Main crops grown are wheat and
Chickpeas (chana), while other crops grown include Pigeon pea/Red Gram (arhar), Red Lentils
(masoor), and Black Gram (udad).
In terms of infrastructure almost all villages reported lack or limitations of basic infrastructure.
Roads were inadequate and not traversable especially during the rainy season. Public transport was
lacking and most interior villages did not have access to bus services as kaccha roads were in bad
condition. Only one road (Damoh-Hatta Road (SH-49) to Itwa Heeralal) connecting villages
Luhara, Shikarpuara, Itwa Hiralal, Kodiya, Russaili and Sojna was in good condition and
constructed recently under the Pradhan Mantri Gramin Sadak Yojana (PMGSY). These villages
also had access to transport services due to the road. Most of the other villages had accessibility
problems especially during the rainy seasons due to the poorly maintained Kaccha roads.
During the visit it was observed that the school buildings in the villages were lacking in basic
amenities and furniture. Due to the cold weather the classes were held out in the sun. Medical
facilities were inadequate and inaccessible due to lack of transport and bad condition of roads.
Sanitation and drinking water were also not accessible to all. Lacks of irrigation facilities have
affected agricultural activities especially during years of low rainfall. The farmers also reported
loss of crops due to unseasonal rains in the past year. During the visit it was observed that fields
were under crops mainly Chickpeas and one patch of coriander.Viral fever, Malaria, Gastro,
tuberculosis and skin diseases are the common diseases prevalent in the study area. Minor
irrigation scheme ongoing in the area, under this scheme govt. grant allocates to the farmers for
making ponds which called “Balram Ponds” as per reported by agriculture department, Hatta.

4 Environmental Impact Assessment
The impact assessment section of the EIA study systematically identifies, characterizes and
evaluates the potential impacts arising out of the project and prioritizes them through a semi-
quantitative system so that they can be effectively addressed by Environment Management
Plans. Potential environmental impacts may arise out of various sequential activities (as
discussed in section 2.6 of this report) to be undertaken as part of proposed exploratory and
appraisal well drilling in VN-ONN-2009/3exploratory block.
4.1 IMPACT ASSESSMENT METHODOLOGY
An environmental impact identification matrix has been developed to present an overview of
possible interactions between project aspects and components of the environment which may
get impacted. The matrix structure takes into account physical, biological and socioeconomic
components of the environment on one axis (X axis) and activities / aspects of the proposed
drilling project on the other side (Y axis). Aspects (based on phases of activities like pre-
drilling activities, drilling, decommissioning and potential accidental events) and impacts on
environmental components that have been taken into consideration were in line with standard
environment management system terminology. Environmental and socioeconomic
components were identified based on reviewing of applicable legislation and baseline
environment, site reconnaissance visits, discussions with stakeholders and SENES’
professional judgment.
Potential environmental and socio-economic impacts that may result from any of the
identified project aspects has been identified in a matrix based on activity-component
interaction and has subsequently been used to develop an impact evaluation matrix that list
evaluation scores based on significance criteria delineated in section 4.1.2.
4.1.1 Impact Criteria and Ranking
Once all project environmental aspects were comprehensively identified for the different
activities of the project, the level of impact that may result from each of the activity-
component interactions has been assessed based on subjective criteria.
For this, three key elements have been taken into consideration based on standard
environmental assessment methodologies:
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 124 ONGC
Severity of Impact: Degree of damage that may be caused to the environmental
components concerned;
Extent of Impact : Geographical spread of impact around project location and
corridors of activities; and
Duration of Impact: Time for which impact lasts taking project lifecycle into account.
These elements have been ranked in three levels viz. 1 (low), 2 (moderate) and 3 (high) based
on the following criteria provided in Table 4-1 below:
Table 4-1: Impact Prediction Criteria

4.1.2 Impact Significance
The significance of impact has been adjudged based on a multiplicative factor of three
element rankings. The Table 4.2 (below) depicts impact significance in a scale of LOW-
MEDIUM-HIGH and will be used for delineation of preventive actions, if any, and
management plans for mitigation of impacts.
Impact significance has been determined taking into account measures which have been
factored in the design and planning phase of the project. Legal issues have been taken into
account, wherever appropriate in the criterion sets, to aid in ONGC’s effort to comply with
all relevant legislation and project HSE requirements. Additionally, the results of quantitative
impact prediction exercise, wherever undertaken, have also been fed into the process.

- Beneficial Impact - ++
To assist in determining and presenting significance of an impact, an impact evaluation
matrix (Table 4.3) has been developed based on the one developed for the impact
identification exercise. In case an environmental component be impacted by more than one
project activity, higher impact significance ranking has been taken as the significance ranking
for subject receptor. Impacts that have been determined to be having high significance
ranking of “>12” are considered significant and hence require examination in terms of
preventive actions and/or additional mitigation to reduce level of the potential impact.
Recommended additional mitigation measures and management plans are presented in
Chapter 6.
The identified impacts are further discussed in detail in the following section with discussion
focusing on impacts of higher significance. This is followed by a point wise outline of
mitigation measures recommended.

4.2 IMPACT ASSESSMENT
This section discusses the impacts of the project activities on the environmental receptors that
stand to get affected by the project. It discusses probable impacts during various phases of the
project lifecycle on the environmental and socioeconomic components. Rankings for every
activity–component interaction is based on the criterion set earlier and resulting
environmental significance with necessary justification that has been recorded below for
every set of impacts and the same has been represented in evaluation matrices. In broader
context, it is however important to remember that operations related to drilling and testing
activities also include positive socioeconomic impacts in terms of increase in local business
opportunities and on a larger perspective, by providing potential energy security at a national
level.
4.2.1 Visual Impacts & Aesthetics
Visual impacts during proposed drilling operations is anticipated from site clearance and well
site preparation, vehicles involved in transportation of raw materials and personnel, material
stockpiles and physical presence and operation of drilling rig and associated facilities.
During drilling site preparation nearly3.0 ha land will be cleared for construction of drill site.
During site construction activity, dust will be generated from transport of construction
material, machinery and personnel, haphazard dumping of construction waste, domestic
waste from labour camp may cause visual and aesthetic impacts. Such impacts likely to be
particularly experienced by communities residing in villages located in the vicinity(viz.
settlements of Hatta Town, Luhari Village, Mankora Village and Manjhguwan Patol Village
etc.) of proposed wells or access routes. Taking into account the temporary nature of site
preparatory activities and necessary mitigation measures to be implemented by the proponent
with respect to the siting of well locations away from human settlements (use of existing
infrastructure etc.) the impact is not considered to be of major significance.
Visual impact due to the operation of drilling rig and presence of base camp is not considered
major given the temporary nature of exploratory activities (about 120 days) .Also with
drilling waste and process waste water is likely to be temporary stored in impervious pits no
visual impact to this regard is envisaged.
The construction of drill pad, drilling of wells will involve continuous day and night
activities, hence lighting at night could be a source of visual discomfort to the residents of
nearby settlements (Hatta Town, Luhari Village, Mankora Village and Manjhguwan Patol
Village). Other than that, light generated from flaring events might also be visually
discomforting at night. However, such activity is likely to be of intermittent in nature, to
occur only during process upset and testing. Reinstatement of well site not indicative of any
commercially exploitable hydrocarbon reserve is also likely to positively contribute to the site
visual aesthetic.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 128 ONGC
Mitigation Measures
All the construction activity will be restricted within the designated site;
Dust nuisance from construction site will be suppressed through periodical water
spraying at disturbance area;
On completion of work all temporary structures, surplus materials and wastes will be
completely removed;
Domestic solid wastes temporarily stored in the collection point within the well site
camps will be transported to designated solid waste disposal sites at Hatta Town at
regular intervals;
Care will be taken to orient the lights downward during the drilling operations to
reduce the effect of residual lighting.
After decommissioning of rig and associated facilities, drill platform will be removed,
pits & garland drains will be filled up, construction material will be removed &
disposed and drill sites will be restored;
Site will be rehabilitated through laying of top soil.

4.2.2 Impacts on Air Quality
Operation of vehicles and construction machinery
Exhaust emission from operation of construction machinery(bulldozers, excavators, backhoe
etc.) is likely to contribute to air pollutant load (primarily particulate matter, NO2,SO2 etc.) in
the ambient air near well site facilities. However, considering localized nature of impacts,
temporary nature of construction along with necessary mitigation measures likely to be
adopted by the proponent (regular maintenance of vehicles and machineries, checking of
vehicular pollutant emission etc.) the impact is considered to be of low significance.

Construction material transport, storage and handling
During construction phase it is estimated that about 500 m3 of borrow material and 1000 m3
of aggregates will be required for construction of 1 well site , road construction/strengthening
and other site preparatory activities. Fugitive emission is therefore anticipated from
transportation, storage and handling of construction material by contractor personnel.
Generation of such fugitive dust is likely to be governed by micro-meteorological conditions
(wind speed and direction) and transportation route condition (degraded in patches).
However, the construction activity, rig mobilization and decommissioning activity is
temporary and limited movement of project vehicles and adopting specific mitigation
measures (viz. spraying of water, management of vehicle loadings, using covered trucks for
transportation etc.) no significant impact is therefore envisaged.

Operation of Diesel Generator (DG) Sets during Drilling Period and test flaring
The proposed project will involve the operation of diesel driven 2 X 1215 kVA generators for
drilling as well as other purposes. The operation of DG sets will therefore result in the
generation of air pollutants viz. PM, SO2 and NOx, thereby affecting the ambient air quality.
As low sulfur HSD will be used emission of SO2 from burning of diesel will be minimized.
The dispersion of these air pollutants may affect the receptors viz. village settlements located
in near vicinity of the well sites (Hatta Town, Luhari Village, Mankora Village and
Manjhguwan Patol Village) only under exceptional combination of meteorological
conditions. However, considering the temporary nature of drilling phase (approx 120 days
including testing), and provision of adequate DG set stack height for effective dispersion of
air pollutants, no significant impact to this regard is envisaged. Additionally, the proponent
also plans to adopt and implement necessary mitigation measures, as discussed in the
subsequent section, to effectively address potential air quality impacts from DG set operation.
In order to predict the Ground Level Concentrations (GLCs) at various distances from the
source, of the above mentioned pollutants, an air modeling exercise ISCST3 has been

Though, ISCST 3 is a refined model, the model run was carried out based on micro-
meteorology to predict air quality impacts for an average 24 hrs period that may be caused by

operation of two 1215KVA DG sets simultaneously and 2) test flaring. Incremental

Table 4-6 shows that the predicted GLC of PM and NO2 are within the National Ambient Air
Quality Standards of 100 μg/m3 and 80 μg/m3 respectively. The maximum ground level
concentration will be at approximately 1.5 km north from the center of the project site.
Considering the temporary nature of drilling phase (approx. 120 days), and provision of
adequate DG set stack height and flare stack height for effective dispersion of air pollutants,
no significant impact to this regard is envisaged. Additionally the proponent also plans to
adopt and implement necessary mitigation measures as discussed in the subsequent section to
effectively address potential air quality impacts from DG set operation and flaring.
The incremental Ground Level Concentration (GLCs) of the pollutants (as discussed above),
do not exhibit any appreciable decrease in air quality. The impact on ambient air quality is
due to operation of DG set is thus considered to be of low significance.

over the freeboard limit and will be covered.
Water spraying will be done on the approach roads to control re-entrained dust during
dry season;
Engines and exhaust systems of all vehicles and equipment used for the project will
be maintained so that exhaust emissions are low and do not breach statutory limits set
for that vehicle/equipment type.
Appropriate stack height for DG sets and flare stack will be utilized
Personnel Protective Equipments (PPEs) like mask will be provided to workers at site.

4.2.3 Impact on Noise Quality
Potential impact on noise quality is anticipated from vehicular movement, operation of
construction machinery, access road strengthening during well site preparation and operation
of drilling rig and ancillary equipment during drilling operation.
Operation of construction machinery/equipment
Operation of heavy machinery/equipment (DG sets, bulldozers, excavators, backhoe etc.) and
vehicular movement during site preparatory and road strengthening/construction activities
may result in the generation of increased noise levels as specified in the Table 2-5. The same
can be used as a reference for calculating probable noise pressure levels arising out of a
number of such equipment.
The noise related disturbance could be experienced by communities residing in proximity of
the construction site and along material transportation routes. The settlements located close to
the proposed wells could face disturbance due to the proposed construction activities.
Considering the construction phase activities to be of temporary nature, limited daily
movement of project vehicles (3-4 nos. vehicle for transportation of personnel and 8-10 nos.
for material transport) and adequate mitigation measures (viz. equipment maintenance,

is considered to be of low significance.

Operation of drilling rig and ancillary equipment
Operational phase noise impacts are anticipated from operation of drilling rig and ancillary
equipment viz. shale shakers, mud pumps and diesel generators. Studies indicated that noise
generated from operation of drilling rig generally varies in the range of 88-103 dB(A). The
average equivalent noise levels of drilling rig and ancillary equipment has been provided in
the Table 2-6 for reference.
Further, considering drilling to be a continuous operation, noise generated from aforesaid
equipment has the potential to cause discomfort to the local communities residing in
proximity (within 250m) of the rig facility. As mentioned in section 2.4.2some settlements is
located within 0.5 km of the proposed well sites in Luhari, Majhguwan Patol, Mankora and
Hatta Town, therefore noise related impacts to the settlements due to drilling is envisaged.
Occupational health and safety impacts viz. Noise Induced Hearing Loss (NIHL) is
anticipated for personnel working continuously in proximity to such noise generating
equipment. However, drilling activities will be undertaken for short duration (approx 120
days for drilling phase) and necessary noise prevention and control measures viz. use of
acoustic barriers, provisions for proper PPEs, regular preventive maintenance of equipment
etc. as practiced by the-proponent to reduce the noise impact on the communities residing in
proximity to the well sites.
Noise Level Prediction
A noise modeling exercise was undertaken based on standard noise attenuation equations to
predict noise levels from drilling rig (and ancillary equipment) near sensitive receptors within
200m in presence of a noise barrier. A noise attenuation plot has been developed considering
natural attenuation by distance with noise level predictions.
The noise generated from drilling rig is considered to be about 95.0 dB(A) at a distance of
10m from the rig location. Noise attenuation equations (without any noise barrier) show that
the normal attenuated noise at any receptor points located at a distance of about 100 m and
200 m from the fence-line of the rig, will be in the range of about 75.0 dB(A) and 68.9 dB(A)
respectively. In the absence of an acoustic barrier, the predicted noise levels were found to
exceed the day time noise standard (55 dB (A)). However, with the introduction of a noise
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 136
ONGC
barrier (5 m in height) at the fence-line will be enough to decrease noise levels near sensitive
receptors at 200m to about 56.9 dB (A). However a detailed noise modelling exercise to look
at option of noise reductions will be conducted at the design stage to determine the barrier
specifications. The noise attenuation plot with and without acoustic barrier is presented in
Figure 4-4.

Mitigation Measures:
Typical mitigation measures for noise will include the following:

mufflers & noise enclosures for DG sets and mud pumps) to reduce noise levels at
source, carrying out proper maintenance and subjecting them to rigid noise control
procedures.
Providing noise barrier at the fence line of the well site facing the sensitive receptors

4.2.4 Potential Impact on Land Use
To construct drill site and approach road, approximately 3 ha land (forest land) per well site
will be required. All the wells are identified in agricultural field only and during the
exploratory drilling phase, temporary impact in terms of change in landuse from agricultural
to industrial use is envisage. However, this land use change will not be permanent and if
potential hydrocarbon is not found then site will be restored to its original or previous
condition.
Mitigation Measures
Restrict project activity and storage of materials within the 3 ha land only
Restore the site to its previous landuse before leaving the site.

4.2.5 Impact on Soil Quality
Potential impact on soil quality is envisaged in the form of loss of soil fertility as a result of
site clearance and top soil stripping during well site preparation and accidental spillage
resulting from storage and handling of mud chemicals. Soil quality impacts so identified have
been assessed and evaluated in the section below.
Stripping of top soil
As discussed in the baseline section 2.1.6 the well sites are located in agricultural field. It
was mentioned in section 3.1.9 that soil in agricultural field is fertile in nature. Potential
impacts on the soil resources will be more pronounced during the site preparation as the
potential changes in the soil structure and degradation of the soil quality as a result of
compaction slope stability is more likely during this stage. These have been discussed in
details in the sections below.
Impacts during site preparation and decommissioning
Site preparation would entail stripping and removal of the topsoil, from the project site. The
top soil contains most of the nutrients and organisms that give soil a living character and
productivity. This is likely to affect the productivity of the land but since the project design
takes into account the preservation of the top soil and its subsequently reuse for topping up of
the rehabilitated land the impacts are likely to be less pronounced. In spite of this however,
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 138
ONGC
the fertility of the soil stands to be affected. The success of the restoration measures would be
crucial for the extent of damages to the topsoil.
Similarly the setting up of the rig and associated machinery will require a strong base.
Compaction of the Soil would be required to take the load of the equipment. This compaction
of the Soil within the boundary of the site would result changes in the Soil structure and may
result in alteration in percolation rates, changes in micro drainage patterns. In this case, the
success of the rehabilitation measures would determine the extent of residual impact to the
Soil structure.
During the site preparation loose Soil or uncovered areas has a high potential for erosion.
Removal of vegetation from slopes would also result in increased erosion potential of those
areas.
In case of commercially non-viable hydrocarbon reserve the activity would be temporary and
proper reinstatement of site will be undertaken. Necessary sediment control measures will be
adopted by the proponent during construction phase to prevent discharge of surface run-off
characterized by increased sediment load. Further specific mitigation measures will be
implemented by the proponent to stabilize the top Soil (referred below) to preserve their
fertility characteristics during site restoration. The impact is therefore considered to be of low
significance.
Mitigation Measures for top Soil stabilization
The top Soil will be stored in mound form.
The height of the mound should not be more than 2m
The slope angle should not be more than 30˚
A jute mat will be overlaid on the mound to contain the erosion of top Soil
A garland drain will be constructed around the mound to contain the runoff of top
Soil.

Storage and disposal of drill cuttings and drilling mud
It is estimated that nearly about 300 m3of drill cuttings and 8 m3/day of drilling wastewater
and 5m3/day waste mud are likely to be generated from each well during drilling operation.
Improper storage and disposal of such process waste on open Soil or unlined areas may

SENES 139
ONGC
therefore lead to the contamination of Soil onsite and abutting land if not properly managed.
With the project design planning taking into account construction of HDPE lined impervious
pit of capacity 600 m3 for temporary storage of drill cuttings and their disposal in accordance
with “CPCB Oil& Extraction Industry Standard – Guidelines for Disposal of Solid Wastes”
no significant impact to this regard is envisaged. Further with the proponent catering to the
use of water based mud the drill cuttings and waste drilling mud generated are likely to be
non-hazardous in nature (however, will be tested to establish its nature) and is not anticipated
to pose any potential threat to the Soil environment. The impact is therefore considered to be
of low significance.

Storage and handling of fuel and chemicals
Contamination of Soil can result from the project activities if certain operations like storage
of chemicals and diesel, spent oil and lubricants are not managed efficiently. Storage of
chemicals and fuels, spent lubricants on unpaved surfaces have potential for contamination of
Soil. However, considering that appropriate spill prevention and control measures to be
implemented (refer below) by the proponent the impact is considered to be of low
significance.
Mitigation Measures:
The following mitigation measures are proposed for reducing impact on Soil quality:
Carrying out adequate restoration of Soil, to the extent possible;
Implementing adequate sediment control measures to prevent discharge of untreated
surface run-off characterized by increased sediment load to abutting agricultural land.
Ensuring proper storage of drill cutting (in impervious HDPE lined pits) and
chemicals (paved and bunded areas) to prevent any potential contamination from
spillage.
Implementing appropriate spill prevention and control measures.
Provision of an oil-water separator at the storm water drainage outlet to prevent
discharge of contaminated run-off.

4.2.6 Impact on Hydrogeology & Ground Water Quality
Potential impacts on groundwater resources that could arise as a result of the proposed
drilling activities include the following:
Ground water extraction
Water to meet domestic requirement of operational workforce, drilling mud preparation and
flushing of holes will be sourced through bore wells within the drill site. It is estimated that
on average 50m3/d of water will be required per well for preparation of drilling mud and cater
to domestic requirements. Taking into account drilling to be a temporary activity (approx 120
days) and both Damoh and Chhatarpur being designated as “safe” for groundwater extraction
by the Central Ground Water Authority impact on ground water resource is considered to be
low.
Mitigation Measures
Abstraction of water from deeper aquifer that is presently not used by local villagers
should be used by ONGC

The other impact on the groundwater resource will be due to the drilling activity. The drilling
will be to a depth of 2800 m. Though, through the data logging service one will be aware of
the depth where the drill will cut through the aquifer zone, an un-quantified sudden huge gush
of water does flow out as the rig cuts across the aquifer zone before cementing and casing is
done. Since, as part of the project activity cementing and casing is done within few hours to
protect the groundwater resource and the project area is demarcated by the Central Ground
Water Board (CGWB) as “safe” which do not suffer from heavy withdrawal of water leading
to rapid fall in the aquifer level the impact significance is envisaged to be low.
Drilling, storage of drill cuttings and waste drilling mud
Possibility of contamination of subsurface and unconfined aquifers may exist if the casing
and cementing of the well is not carried out properly leading to infiltration or seeping of
drilling chemicals or mud into porous aquifer region. The same is also valid for disposal of
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.

drilling waste and mud in an open/unpaved pit. However, with the project proponent catering
to the use of water based mud and storage of drill cuttings and waste drilling mud in an
HDPE lined pit, impact is considered to be of low significance.
Mitigation Measures
Proper engineering controls will be used for drilling and cementing operations
Water based, non-hazardous type of drilling mud will be utilized for drilling operation
Drill cuttings & mud will be stored in HDPE lined pits as per S No. 72 C.1.a Schedule

4.2.7 Impact on Surface Water Quality
Impact on surface water quality of natural drainage channels and community water bodies
may arise from discharge of contaminated surface run-off, sewage and process waste water
generated during various phases of the proposed project.
Surface run-off discharge
As discussed under section 4.2.5, site clearance and stripping of top Soil during site
construction will result in an increase in Soil erosion potential leading to an increased
sediment load in the surface run-off during monsoon. Also, surface run off from drilling
waste (cuttings and drilling mud), hazardous waste (waste oil, used oil etc) and chemical
storage areas may lead to the pollution of receiving water bodies viz. natural drainage
channels etc unless precautionary measures are adopted. As the locals in the area use the
streams (Kopra and Sonar river) as potable water source, any contaminated discharge to the
surface water channels may lead to potential health impacts of the locals. However, taking
into account the provision of onsite drainage system, sediment control measures, provision of
oil water separator will aid discharging of surface run off in compliance with the CPCB
Inland Water Discharge Standards, the impact is considered to be of low significance.

Discharge of drilling mud and process wash water
It is estimated that nearly about 5 m3/day of drilling mud and 8 m3/day process wastewater is
likely to be generated during drilling operation. The drilling waste so generated may be
characterized by the presence of Oil & grease, barites and heavy metal which on discharge to
nearby natural drainage channels and/or rivers may lead to possible surface water
contamination. As mentioned earlier discharge of contaminated water at the streams could
lead to potential health impacts for the locals. However, considering usage of water based
mud for the proposed project, temporarily storage of drilling waste in an HDPE lined pit to
ensure conformance with CPCB Industry Specific Standards for oil Drilling & Gas Extraction
Industry and guidelines provided by the MoEF&CC under the Hazardous Wastes
(Management, Handling & Transboundary Movement) Rules, 2008 the impact is considered
to be of low significance.
Mitigation Measures
Following mitigation measures will be implemented for surface water pollution control:
Proper treatment of all wastewater and produced water and any water discharge from
well site to should comply with CPCB Inland Water Discharge Standards for oil and
Gas Industries
Waste mud to be stored in the cuttings pit
Drainage and sediment control systems at the well site will be efficiently designed
Construction activities viz. stripping, excavation etc during monsoon season will be
restricted to the extent possible.
All chemical and fuel storage areas, process areas will have proper bunds so that
contaminated run-off cannot escape into the storm-water drainage system.
An oil-water separator will be provided at the storm water drainage outlet, to prevent
discharge of contaminated run-off.

4.2.8 Impact on Biological Environment
The potential impacts on ecological habitat of the VN-ONN-2009/3 PEL Block due to
proposed drilling operations are discussed below:
Loss of flora and floral habitat
As mentioned earlier, ONGC is now proposing to start its drilling activities at one location
and extend it to further three potential locations. Although the north part of the block covers a
lot of forested areas, but the proposed potential four oil wells (to be drilled sites) are located
in the abandoned agricultural lands. During the drilling activities, the ground cover mostly
occupied by seasonal grasses/sedges/weeds would be removed. No tree felling is envisaged.
If at all there is any need for tree felling, ONGC shall approach the local forest official and to
get approval for the same.
Impact of Fauna & Faunal Habitat
As the proposed potential oil well locations located in the agricultural lands (although
abandoned), these areas are highly disturbed for most sensitive wildlife. The only faunal
species observed from these areas were a few domestic common birds; Rhesus macaque,
Hanuman langurs, common mongoose, squirrel, garden lizard etc. The sound produced by the
drilling operation consists of loud mechanical noises emitted over a range of frequencies and
intensities. Noise generated from drilling operations and vehicular movement within the drill
site is likely to affect the fauna leading them to move away/migrate from the project activity
areas and its immediate vicinity to safer place/less disturbed places as a normal practice.
Such disturbance may be impacted approximately to a distance of 0.5 km.
The physical presence of drilling rig is also to be felt at night because of the illuminated at
night by lighting arrangements. Other possible sources of illumination will be flaring
conducted for a short period of time during well testing phase. Artificial lighting and well
testing flares may result in the attraction of some wildlife and birds leading to their
disorientation and confusion behaviour.
Construction activities and drilling would take place for a short duration (about 4 months) ,
and the land use pattern of the surrounding areas are similar to the proposed drilled sites.
These faunal species can take refuge in these areas. The level of impact on small mammalian
species (irrespective of their scheduled category as per IWPA) from the construction related
activities can be considered as medium significance although it is short term.
4.2.9 Impact on Socioeconomic Environment
Based on the nature and type of impacts, the assessment has been divided into broad
categories namely (i) Adverse impacts and (ii) Positive impacts.
Adverse Impact
Loss of Livelihood
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 144
ONGC
The proposed well sites will be located at agricultural land and nearest settlement to the well
sites are located more than 100 m away. Approximately, 3 ha land per well will be required
for proposed drilling activity. As the lands is agricultural land therefore loss of livelihood is
envisage. However, considering the short duration and temporary nature of exploratory
drilling, impact would not be of long term. Also, provision of crop compensation and taking
land on lease after discussion with land owners, adverse impact will also be mitigate.
Job Opportunity
Conflicts related to opportunity of jobs may arise as the locals would expect employment
generation for them from the drilling activities.Local villagers would be involvement in the
construction works, however during drilling skilled personnel would be required and
employment opportunities for the locals would be limited. Involvement of outside workers in
proposed activity may possibly create conflict with the local people, as most of the villagers
are small scale cultivators, workers, daily labours or small businessmen. The impact on job
conflict will be low if more unskilled opportunities are given to the locals during the
construction phase thus reducing the medium significance to low.

Disruption on Infrastructure
The width of the approach roadis not wide enough to support the movement of heavy
vehicles to well site location, hence they have to be widened and strengthened. Further, new
approach road need to be constructed at some places such as well site “R-HAT-A” proposed
in Luhari Village. Transportation of drilling rig and associated facilities to drill and
decommissioning of rig and associated structure will increase traffic movement. Increase in
vehicular fleet may cause damage to road infrastructure if not properly maintained. The
strengthening and widening of the existing road will reduce the significance of impact from
medium to low.

Dust and Noise Discomfort
The proposed well sites are located minimum 100 m away from the settlements. Settlements
are also located adjacent to the access roadsto the sites. Inhabitants residing close to access
roads will be affected due to noise and dust generated from heavy vehicular movement during
site preparation, setting up of rig, decommissioning of rig and considering distantly located
settlements from the well sites and short term activity with proper mitigation measures
(construction of pucca approach roads; sprinkling of water in access roads; using noise
barrier at the boundary of the well sites), the significance of the impact will be reduced from

Influx of population is anticipated in all stages of the project cycle particularly during
exploratory drilling. The drill site will involve the operation of about 60 onsite workers
during drilling phase. Interaction between workers with villagers of nearby areas might give
rise to various issues like conflict of workers with the local population, nuisance caused by
workers due to improper sanitation facilities, etc.However, taking into account that majority
of the workforce during construction phase is likely to be sourced from local villages and
adequate sanitation facilities will be provided chances of such conflicts are negligible.

is no designated historical orcultural spots close to the well sites or access roadshence; no
impact in this regard is envisaged .
Employment opportunities
Project will benefit people living in the neighboring villages temporarily by giving preference
to them in relation to direct & indirect employment associated with the various project
activities during exploratory drilling phase. Site preparation phase will involve certain
number of laborers and there is a possibility that local people can be engaged for this
purpose. Drilling process will involve a number of skilled and unskilled workers. Generation
of short time employment opportunities during the project phase would improve the
employment scenario of the area.
However, most jobs will comprise technical involvement. Hence villagers can possibly be
employed only in certain non-technical or casual labor jobs and that too for a limited
duration.
Social Action Plan
Mitigation and or Benefits
For Loss of Livelihood
Instead of land purchase or acquisition lease of land for drilling and subsequently return of
land to the land owner.
During the construction phase there will be both direct and indirect benefits to the local
population. Direct benefits includes hiring or purchase of goods and services during the
construction period includes employment of categories of unskilled labour, purchase of
consumption items, rentals (accommodations /premises, land, vehicles, equipment’s etc.).
Increased people movement due to the project within the locality will increase petty business
opportunities (pan shops, food and beverages shops, cycle repair shops etc) for a short period
of time.
Disruption of Infrastructure
By strengthening and expansion of existing roads conflicts related to deterioration of roads
can be avoided. Further in consideration of the anticipated increase in both vehicular traffic
and labour influx a traffic management plan will be prepared and implemented by the Client
to avoid conflicts out of any accidents and incidents due to increased traffic.
Dust and Noise
Specific mitigation measures will be required to be implemented including construction of
pucca approach roads; sprinkling of water in access roads; using noise barrier at the boundary
of the well sites. Other mechanisms such as stakeholder engagement and grievance redressal
mechanism will also be implemented at site to address any such issues arising out of project
construction and reduce conflicts.
Influx of Population
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 147
ONGC
Labour influx is anticipated at all stages of the project considering the paucity of skilled
labour from the local villages. To reduce conflicts all unskilled and semi skilled labour will
be sourced from local villages. Labour management plan will be formulated and implemented
to avoid and mitigate any such issue arising from influx of labour. The LMP will address and
implement various measure required for waste disposal including waste water.
Health and Safety Issues
All construction work should be undertaken only after fencing off the area. Display boards
should be displayed in the local language Hindi and English to prevent people from entering
the construction area and make them aware of the dangers associated with the construction
activities and machinery on site.
4.2.10 Impact on Occupational Health and Safety
Occupational injuries and ill-health have huge socio-economic implications on individuals,
their families and communities. They also have economic impacts in form of direct and
indirect costs for society as a whole. Major occupational health risks encountered in proposed
drilling activity include noise from drilling activity, operation of heavy vehicles and
machinery, handing of chemicals.
However, the proponent will adopt necessary control measures through implementation of
mitigation measures and provision of proper PPEs to workers operating in aforesaid area to
prevent and/or mitigate adverse health related impacts. Hence any possible occupational
health impact from exposure to such fugitive dust is not likely to be of major significance.

4.2.11 Community Health & Safety:
Community health and safety of inhabitants residing close to the drilling site stands to get
affected from frequent heavy vehicular movement along village access roads and due to noise
from drilling rig operations. Health and safety impact arising from technological emergencies
viz. well blow outs, explosions will be dealt separately in the Quantitative Risk Assessment
(QRA) section. Although the aforesaid activities are temporary in nature it may not adversely

affect community health and safety in the long term. Mitigation measures will be taken as
outlined Sec 6.1.1 A-E to reduce the impacts arising out of project activities and hence
significance will reduce from medium to low significance.
Few mitigation measures would be adopted to protect the community are as follows
Drilling activities should be under proper fencing
Proper hoardings in English and local language should be displayed during
construction and operation phase to prevent people from encroaching the fenced area
or to make them aware of the danger associated with the construction

QRA as a part of integrated risk management process for the proposed project consists of the
following iterative steps:
Identification of hazards
Setting Acceptance Standards for the defined risks
Evaluation of likelihood and consequences and risks of possible events.
Confirmation of arrangements to mitigate the events and respond to the same on occurrence.
Establishment of performance standards
Establishment of continuous monitoring, review and auditing of arrangements
5 Quantitative Risk Assessment
This section on Quantitative Risk Assessment (QRA) aims to provide a systematic analysis of
the major risks that may arise as a result of drilling and testing activities by ONGC in the
VN-ONN-2009/3 PEL Block. The QRA process outlines rational evaluations of the identified
risks based on their significance and provides the outline for appropriate preventive and risk
mitigation measures. Results of the QRA provides valuable inputs into the overall project
planning and the decision making process for effectively addressing the identified risks. This
will ensure that the project risks stay below As Low as Reasonably Practicable (ALARP)
levels at all times during project implementation. In addition, the QRA will also help in
assessing risks arising from potential emergency situations like a blow out and develop a
structured Emergency Response Plan (ERP) to restrict damage to personnel, infrastructure
and the environment.
BOX 5.1: QRA – INTEGRATED RISK MANAGEMENT PROCESS
The risk study for the drilling and testing activities has considered all aspects of operation of
the drilling rig and other associated activities during the drilling phase. Oil spills, loss of well
control / blow-out and process leaks constitute the major potential hazards that may be
associated with the proposed drilling for oil and gas in the VN-ONN-2009/3 PEL Block.
The following section describes objectives, methodology of the risk assessment study and
then presents the assessment for each of the potential risk separately. This includes
identification of major hazards, hazard screening and ranking, frequency and consequence
analysis for major hazards. The hazards have subsequently been quantitatively evaluated
through a criteria based risk evaluation matrix. Risk mitigation measures to reduce significant
risks to acceptable levels have also been recommended as a part of the risk assessment study.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 153 ONGC
5.1 OBJECTIVE OF THE QRA STUDY
The overall objective of this QRA with respect to the proposed project involves identification
and evaluation of major risks, prioritizing risks identified based on their hazard consequences
and formulating suitable risk reduction/mitigation measures in line with the ALARP
principle. Hence in order to ensure effective management of any emergency situations (with
potential individual and societal risks) that may arise during the drilling activities, following
specific objectives need to be achieved.
Identify potential risk scenarios that may arise out of proposed drilling activities like
operation of ancillary facilities and equipment, mud chemicals storage and handling
etc.
Analyze the possible likelihood and frequency of such risk scenarios by reviewing
historical accident related data for oil and gas industries.
Predict the consequences of such potential risk scenarios and if consequences are
high, establish the same by through application of quantitative simulations.
Recommend feasible preventive and risk mitigation measures as well as provide
inputs for drawing up of Emergency Management Plan (EMP) for the project.
5.2 RISK ASSESSMENT METHODOLOGY
The risk assessment process is primarily based on likelihood of occurrence of the risks
identified and their possible hazard consequences particularly being evaluated through
hypothetical accident scenarios. With respect to the proposed project, major risks viz. blow
outs, process leaks and fires, non-process fires etc. have been assessed and evaluated through
a risk matrix generated to combine the risk severity and likelihood factor. Risk associated
with the drilling activities have been determined semi- quantitatively as the product of
likelihood/probability and severity/consequence by using order of magnitude data (risk
ranking = severity/consequence factor X likelihood/probability factor). Significance of such
project related risks was then established through their classification as high, medium, low,
very low depending upon risk ranking.
The risk matrix is a widely accepted as standardized method of quantitative risk assessment
and is preferred over purely quantitative methods, given that its inherent limitations to define
a risk event is certain. Application of this tool has resulted in the prioritization of the potential
risks events for the drilling thus providing the basis for drawing up risk mitigation measures
and leading to formulation of plans for risk and emergency management. The overall
approach is summarized in the Figure 5.1
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 154 ONGC
FIGURE 5-1: RISK ASSESSMENT METHODOLOGY
5.2.1 Hazard Identification
Hazard identification for the purposes of this QRA comprised of a review of the project and
associated activity related information provided by ONGC as part of its Emergency Response
Plan. In addition, guidance provided by knowledge platforms/portals of the upstream oil &
gas industry including oil Industry Safety Directorate (OISD), Directorate General of Mines
Safety (DGMS), OGP, ITOPF and DNV, Norwegian Petroleum Directorate, etc. are used to
identify potential hazards that can arise out of proposed project activities.
Taking into account the applicability of different risk aspects in context of the drilling
operations to be undertaken in the VN-ONN-2009/3 PEL Block, there are three major
categories of hazards that can be associated with proposed project which has been dealt with
in detail. This includes:
Blowouts leading to pool fires/jet fires and Oil spills
Process leaks and fires
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 155 ONGC
Non-process fires / explosions
Well control incident covers a range of events which have the potential of leading to blow-
outs but are generally controlled by necessary technological interventions. Hence, such
incidents are considered of minor consequences and as a result not well documented. Other
possible hazard scenarios like mud chemical spills, falls etc. has also not been considered for
detailed assessment as preliminary evaluation has indicated that the overall risk that may
arise out of them would be low. In addition, it is understood that, causative factors and
mitigation measures for such events can be adequately taken care of through existing safety
management procedures and practices of ONGC.
It must also be noted here that many hazards identified are sometimes interrelated with one
hazard often having the ability to trigger off another hazard through a domino effect. For
example, a large oil spill in most instances is caused by another hazardous incident like a
blowout or process leak. This aspect has been considered while drawing up hazard mitigation
measures and such linkages (between hazards) has also been given due importance for
managing hazards and associated risks in a composite manner through ONGC’s Health,
Safety & Environmental Management System (HSEMS) and through the Emergency
Response Plan, if a contingency situation so arises.
5.2.2 Frequency Analysis
Frequency analysis involves estimating the likelihood of each of the failure cases identified
during the hazard identification stage. The analysis of frequencies of occurrences for the key
hazards that has been listed out is important to assess the likelihood of such hazards to
actually unfold during the lifecycle of the project. The frequency analysis approach for the
proposed project is based primarily on historical accident frequency data, event tree analysis
and judgmental evaluation. Major Oil and gas industry information sources viz. statistical
data, historical records and global industry experience were considered during the frequency
analysis of the major identified risks3.
For QRA for the proposed project, various accident statistics and published Oil industry
databases have been consulted for arriving at probable frequencies of identified hazards.
However, taking into account the absence of representative historical data/statistics with
respect to onshore operations4, relevant offshore accident databases have been considered in
the frequency analysis of identified hazards. The same has been recommended in the “Risk
Assessment Data Directory” published by the International Association of Oil & Gas
Producers (OGP). Key databases/reports referred as part of the QRA study includes
3 It is to be noted that the frequency of occurrences are usually obtained by a combination of component
probabilities derived on basis of reliability data and /or statistical analysis of historical data.
4 Although Alberta Energy & Utilities Board (EUB) maintains a database for onshore incidents for the period
1975-1990 the same has not been considered in the context of the present study as the Alberta wells are believed
to be sour with precaution being taken accordingly to minimize the likelihood of release.

SENES 156 ONGC
Worldwide Offshore Accident Databank (WOAD), Outer Continental Shelf (OCS) Reports,
Norwegian Petroleum Directorate Directives, Offshore Reliability Data (OREDA)
Handbook, HSE Offshore Incident Database, SINTEF Offshore Blowout Database etc.
Based on the range of probabilities arrived at for different potential hazards that may be
encountered during the proposed drilling activities, following criteria for likelihood rankings
have been drawn up as presented in the Table 5-1.
Table 5-1: Frequency Categories and Criteria
Likelihood Ranking Criteria Ranking
(cases/year) Frequency Class
5 >1.0 Frequent
4 >10-1 to <1.0 Probable
3 >10-3 to <10-1 Occasional/Rare
2 >10-5 to <10-3 Not Likely
1 >10-6 to <10-5 Improbable
5.2.3 Consequence Analysis
In parallel to frequency analysis, hazard prediction / consequence analysis exercise assesses
resulting effects in instances when accidents occur and their likely impact on project
personnel, infrastructure and environment. In relation to the proposed project, estimation of
consequences for each possible event has been based either on accident experience,
consequence modeling or professional judgment, as appropriate.
Given the high risk perception associated with blow outs in context of onshore drilling
operation, a detailed analysis of consequences has been undertaken for blow outs taking into
account physical factors and technological interventions. Consequences of such accidental
events on the physical, biological and socio-economic environment have been studied to
evaluate the potential of the identified risks/hazards. In all, the consequence analysis takes
into account the following aspects:
Nature of impact on environment and community;
Occupational health and safety;
Asset and property damage;
Corporate image
Timeline for restoration of environmental and property damage
Restoration cost for environmental and property damage
The following criterion for consequence rankings (Table 5-2) is drawn up in context of the
possible consequences of risk events that may occur during proposed drilling activities:

5.3 RISK ASSESSMENT OF IDENTIFIED PROJECT HAZARDS
As already discussed in the previous section, three major categories risk have identified in
relation to proposed drilling activities. A comprehensive risk assessment study has been
undertaken to assess and evaluate significance of identified risks in terms of severity of
consequences and likelihood of occurrence. Risk assessment study details have been
summarized in the subsequent sections below:
5.3.1 Blow Outs/Loss of Well Control
Blow out is an uncontrolled release of well fluid (primarily hydrocarbons viz. Oil and/or gas
and may also include drilling mud, completion fluid, water etc.) from well bore. Blow outs
are the result of failure to control a kick and regain pressure control and are typically caused
by equipment failure or human error. The possible blow out cause events occurring in
isolation or in combination have been listed below:
Formation fluid entry into well bore
Loss of containment due to malfunction (viz. wire lining)
Well head damage (e.g. by fires, storms, dropped object etc.)
Rig forced off station (e.g. by anchor failure) damaging Blow Out Preventor (BOP) or
wellhead
The most common cause of blow out can be associated with the sudden/unexpected
entry/release of formation fluid into well bore that may arise as a result of the following
events as discussed in the Box 5.2 below.
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 160 ONGC
BOX 5.2: PRIMARY CAUSES OF BLOW OUTS
Shallow gas
In shallow formations there may be pockets of shallow gas. In these instances there is often insufficient
mud density in the well and no BOP is in place. If the hole strikes shallow gas the gas may be released on
the drilling rig very rapidly. Typical geological features which suggest the presence of shallow gas can
then be detected. Historically, striking of shallow gas has been one of the most frequent causes of
blowouts in drilling.
Swabbing
As the drill pipe is pulled upwards during trips out of the hole or upward movement of the drill string, the
pressure in the hole beneath the drill bit is reduced, creating a suction effect. Sufficient drilling mud must
be pumped down-hole to compensate for this effect or well fluids may enter the bore. Swabbing is also a
frequent cause of drilling blowouts.
High formation pressure
Drilling into an unexpected zone of high pressure may allow formation fluids to enter the well before mud
weight can be increased to prevent it.
Insufficient mud weight
The primary method of well control is the use of drilling mud; in correct operation, the hydrostatic
pressure exerted by the mud prevents well fluids from entering the well bore. A high mud weight
provides safety against well fluids in-flows. However, a high mud weight reduces drilling speed,
therefore, mud weight is calculated to establish weight most suitable to safely control anticipated
formation pressures and allows optimum rates of penetration. If the required mud weight is incorrectly
calculated then well fluid may be able to enter the bore.
Lost Circulation
Drilling mud circulation can be lost if mud enters a permeable formation instead of returning to the rig.
This reduces the hydrostatic pressures exerted by the mud throughout the well bore, and may allow well
fluids from another formation to enter the bore.
Gas cut mud
Drilling fluids are denser than well fluids; this density is required to provide the hydrostatic pressure
which prevents well fluids from entering the bore. If well fluids mix with the mud then its density will be
reduced. As mud is circulated back to surface, hydrostatic pressure exerted by the mud column is reduced.
Once gas reaches surface it is released into the atmosphere.

For better understanding, causes of blow outs have been systematically defined in terms of
loss of pressure control (failure of primary barrier), uncontrolled flow of fluid or failure of
secondary barrier (BOP). The blow out incidents resulting from primary and secondary
failures for proposed operations as obtained through comprehensive root cause analysis of the

Thus, underlying blowout causes as discussed in the above table can be primarily attributed
to swabbing as the primary barrier failure which is indicative of insufficient attention given to
trip margin and controlling pipe movement speed. Also, it is evident from the above table that
lack of proper maintenance, operational failures and absence of BOPs as secondary barrier
contributed to majority of blowout incidents (approx 30 nos.) is recorded.
Blowout Frequency Analysis
Blow out frequency estimates is obtained from a combination of incident experience and
associated exposure in a given area over a given period. For the purpose of calculation of
blow out frequency analysis in context of the present study involving drilling operations,
blow out frequencies per well drilled have been considered. However due to the lack of
availability of representative data on onshore blow out incidents relevant offshore accident
database viz. SINTEF Offshore Blowout Database, OGP Risk Assessment Data Directory
(RADD) and Scandpower which have been referred. The blow out frequency per operation as
calculated is based on the SINTEF Offshore. Blowout Database for Oil and gas extraction
industry has been presented in the Figure 5-2 below.

FIGURE 5-2: BLOW OUT FREQUENCIES IN OIL & GAS INDUSTRY
With respect to the proposed project, the blow out occurrence frequency as based on analysis
of historical data6 has been considered to be 7.5 X 10-3 per well drilled. Based on the given
frequency and information provided by ONGC on the proposed project drilling program the
blow out frequency is calculated as follows:
No of wells to be drilled = 4(A)
Blow out frequency for drilling = 7.5 X 10-3 per well drilled (B)
Frequency of blow out occurrence for the proposed project = (A X B) = 4 X 7.5 X 10-3
= 3.00 X 10-2per well drilled
Thus, the blow out frequency for the proposed project is calculated at 3.0 X 10-2per well
drilled i.e. the likelihood of its occurrence is “Occasional/Rare”
Blowout Consequence Analysis
Blow out from a hydrocarbon well may lead to the following possible risk consequences:

Oil slicks resulting from un-ignited oil pools.
Pool fire
A pool fire is a turbulent diffusion fire burning above a pool of vaporizing hydrocarbon fuel
where the fuel vapor has negligible initial momentum. The probability of occurrence of pool
fires for oil and gas exploration is high due to continuous handling of heavy hydrocarbons.
The evaporation of hydrocarbons from a pool forms a cloud of vapor above the pool surface
which, on ignition, leads to generation of pool fire.
For the purpose of consequence modeling for pool fires resulting from blow outs, following
hypothetical scenarios in terms of hydrocarbon (particularly crude Oil) release rates (Table 5-
6) have been considered based on DNV Technica’s FLARE program.
TABLE 5-6: POOL FIRE MODELING SCENARIOS
Scenario Release Rate (kg/s) Release Type
Scenario - I 1 Small
Scenario - II 10 Medium
Scenario – III (Worst Case) 50 Large
The release rates as specified for the aforesaid scenarios have been utilized in the computing
the pool fire diameter utilizing the following equation and input parameters:
D = √4Q/πb
Where D = pool diameter (m)
Q = release rate (kg/s)
b = burning rate (kg/m2s)
The mass burning rate for crude Oil has been considered to be 0.05 kg/m2s
Based on above equation, the pool fire diameter and the steady study burning areas computed
for various release types have been presented in the Table 5-7 below.

The impact zone for long duration fires is conveniently described by thermal radiation
contours and its effects on the people who are exposed to such radiation levels for one minute
(60sec). The thermal radiation threshold values (measured in kilowatts per square meter)
defined for crude Oil pool fire consequence modeling is provided in Table 5-8 below:

radiation intensity of 37.5 kW/m2 is likely to be experienced to a maximum distance of

Jet fire
Jet fires are burning jet of gas or sprays of atomized liquids resulting from gas and
condensate release from high pressure equipment and blow outs. Jet fires may also result in
the release of high pressure liquid containing dissolved gas due to gas flashing off and
turning the liquid into a spray of small droplets. In context of the present study, formation of
jet fires can be attributed by the high pressure release and ignition of natural gas if
encountered during exploration of block hydrocarbon reserves.
Natural gas as recovered from underground deposits primarily contains methane (CH4) as a
flammable component, but it also contains heavier gaseous hydrocarbons such as ethane
(C2H6), propane (C3H8) and butane (C4H10). Other gases such as CO2, nitrogen and hydrogen
sulfide (H2S) are also often present. Methane is typically 70-90 percent, ethane 5-15 percent,
propane and butane, up to 5 percent. Thus, considering higher percentage of methane in
natural gas, the thermo-chemical properties of the same has been utilized in the jet fire blow
out consequence modeling. The following risk scenarios (Table 5-10) have been considered
for jet fire consequence modeling:
TABLE 5-10: JET FIRE MODELING SCENARIOS
Scenario Release Rate (kg/s) Release Type
Scenario - I 1 Small
Scenario - II 5 Medium
Scenario – III (Worst Case) 10 Large
Gas release rates for each scenario have been utilized in the calculating jet fire flame length.
Flame length calculation is done using API RP521 (API 1982) model and is based on the fuel
type
Lf = 0.00326 (Q Hc) 0.41
Where
Lf = flame length (m)
Q = release rate (kg/s)
Hc = heat of combustion (J/kg) i.e. (5.0 X 107 J/kg for methane)
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 166 ONGC
The flame length calculated based on the above equation for jet fire is presented in the Table
5-11 below.

Scenario Release Rate (kg/s) Release Type Flame Length (m)
Scenario - I 1 Small 4.68
Scenario - II 5 Medium 9.04
Scenario – III (Worst Case) 10 Large 12.02
The thermal radiation intensity threshold values and its possible impacts for jet fire is similar
to that considered for pool fire (Refer Table 5-8) The distance to the radiation intensity levels
for risk scenarios have been predicted based on the Chamberlain model calculation. The
following relationships for distance along the flame axis to various thermal radiation levels
have been calculated:
For 5.0 kW/m2; Lf = 19.50 (Q) 0.447
For 12.5 kW/m2; Lf = 16.15 (Q) 0.447
For 37.5 kW/m2; Lf = 13.37 (Q) 0.447
Where Lf = flame length (m)
Q = release rate (kg/s)
Based on equation specified for thermal radiation intensities the distance of flame calculated
for various gas release rates under risk scenarios discussed have been presented in the Table
5-12 below.

As provided in the above table the flame length for the jet fire risk scenarios considered at

16.2 – 45.2m for 12.5 kW/m2 thermal radiation

the source with potential lethal effects likely to be experienced within 8 sec.

Oil Spill
Crude oil spills resulting from blow out may result in the formation of un-ignited pools of
liquid the spreading of which is governed by physical factors viz. wind speed, sea currents
(for offshore spills), release rates and spilled chemical characteristics viz. density. Near to the
source of a continuous release, the spreading is dominated by gravity and limited by internal
forces with thickness generally varying within 10-20 mm. The spill movement is then resisted
by the viscous shear forces which then continue until the spill thickness is about 1.0 mm.
Subsequently, surface tension takes over as the dominant spreading mechanism and it
continues until the thickness has reduced to 0.01 – 0.1 mm which may take about 7-10 days
for a large spill depending on various factors as discussed earlier.
With respect to the QRA study hypothetical release rates of 1.0kg/s, 5.0 kg/s and 10.0 kg/s
for 1 day, 4days and 7days respectively have been considered as the possible risk scenarios
for modeling the spread of oil spill following a blow-out incident. The diameter of the pool in
the first phase of an unignited continuous release is obtained by the following equation:
D = 2 [g X Q/ρL 2π] t3/4
Where
D = pool diameter (m)
g = acceleration due to gravity (m/s2)
Q = release rate (kg/s)
ρL = liquid density (kg/m3) (crude oil density is 790 kg/ m3)
t = time since start of release (s)
The pool fire diameter so calculated for the aforesaid risk scenarios have been presented in
the Table 5-13 below.
TABLE 5-13: POOL DIAMETER FOR OIL SPILL RISK SCENARIOS
Release Type Release Rate (kg/s) Release Time (s) Oil Spill Pool Diameter (m)
Small 1 86400 19.9
Medium 5 259200 226.9
Large 10 432000 665.7
Hence, for a worst case spill scenario involving a crude oil release rate of 10kg/s for a period
of 7 days the pool diameter for an un-ignited continuous release is predicted to be about
665.7 m. The ignition of the oil pool may lead to the formation of pool fires - consequences

of which have been discussed earlier under the risk related to pool fires. Although the un-
ignited pool is not considered to be of major significance, it may gain significance based on
the environmental impacts that may result from it depending on sensitive receptors identified
abutting the proposed project well sites.

Preventive and Mitigation Measures
Blowouts being events which may be catastrophic to any well operation, it is essential to take
up as much a preventive measures as feasible. This includes:
Necessary active barriers (eg. Well-designed Blowout Preventor) be installed to
control or contain a potential blowout.
Weekly blow out drills be carried out to test reliability of BOP and preparedness of
drilling team.
Close monitoring of drilling activity be done to check for signs of increasing pressure,
like from shallow gas formations.
Installation of hydrocarbon detectors.
Periodic monitoring and preventive maintenance be undertaken for primary and
secondary barriers installed for blow out prevention, including third party inspection
& testing
An appropriate Emergency Response Plan be finalized and implemented by ONGC.
Marking of hazardous zone (500 meters) around the well site and monitoring of
human movements in the zone.
Training and capacity building exercises/programs be carried out for onsite drilling
crew on potential risks associated with exploratory drilling and their possible
mitigation measures.
Installation of mass communication and public address equipment.
Good layout of well site and escape routes.
Additionally, ONGC will be adopting and implementing the following Safe Operating
Procedures (SOPs) developed as part of its Onsite Emergency Response Plan to prevent and
address any blow out risks that may result during drilling activities:
Blow Out Control Equipment
Choke lines and Choke Manifold Installation with Surface BOP

5.3.2 Process Leaks/Fires
Process leaks are can be defined as hydrocarbon releases from process equipment (flanges,
valves, pressure vessel etc.) excluding blowouts and are relatively frequent events. In most
cases they are small in nature and can be effectively controlled. However, if this is not
possible, they can trigger events like fire or explosions which may potentially have higher
consequences.
Process Leaks – Frequency Analysis
The frequency of process leaks can be estimated directly from analysis of historical data
obtained from E & P Forum hydrocarbon leak database (E&P forum 1992), World Offshore
Accident Database (WOAD) and OREDA. Although onshore data is available for process
leaks, the information is not considered representative of the actual scenario. Under such
circumstances historical data available on hydrocarbon leaks in the OGP authenticated
offshore accident databases have been considered for purpose of process leak frequency
analysis. Review of HSE hydrocarbon release database indicates that majority of the leaks
(approx 45%) occurred during production with drilling/well operation contributing is only
10%. Range of frequencies for various possible events is presented in the Table 5-14 below.
TABLE 5-14: LEAK FREQUENCIES FOR PROCESS EQUIPMENT
Equipment Type Frequency
(per equipment item year)
Flanges 8.8 X 10-5
Valves 2.3 X 10-4

Pumps, reciprocating, double seal 3.1 X 10-1
Compressors, centrifugal 1.4 X 10-2

Hence, with the proposed project span over a period of 2 years, frequency analysis for the
process leaks from various process equipmentsare calculated as follows (Table 5-15)

Compressors,
centrifugal 1.4 X 10-2 2 2.80 X 10-2 Probable
Compressors,
reciprocating 6.6 X 10-1 2 1.32 Frequent
Thus, as discussed above in most of the cases the frequency of occurrence of process leaks
for the proposed project is either “Not Likely” or “Probable” with hydrocarbon release from
reciprocating pumps and compressor is predicted to be “Frequent”. Further, taking into
account that ONGC plans to undertake periodic monitoring and preventive maintenance of
such process equipment’s occurrence of such process leaks is likely to be less frequent.
Process Leaks – Consequence Analysis
The potential consequences of a hydrocarbon leak from process equipment (flanges, valves,
pressure vessel etc.) will depend, to a large extent on steps that can be taken to control or
mitigate effect. There is considerable chance that a process leak might be ignited (either
immediate or delayed) resulting in a fire or explosion. The following scenarios can occur if a
hydrocarbon leak is ignited:
Jet fires resulting from gas releases ignited early
Pool fires and smoke plumes from ignited oil releases.
The evolution of a fire or explosion scenario as a result of a process leak can follow a
complex chain of events which can be studied in further detail through a fault tree or what-if
analysis. Fires or explosions resulting from ignition of hydrocarbon leaks can cause severe
consequences, if it goes out of control and can damage equipment’s, including the drilling rig
itself and can have severe adverse effect on the surrounding environment
The process leak consequences viz. jet fire and pool fire is likely to arise out of an ignition of
the oil pool/vapour cloud formed. However, the same is dependent on the ignition
probabilities accounted in relevant databases maintaining records of accidental events
occurring over the years with respect to oil and gas industry. Review of the SINTEF
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 171 ONGC
database for major and minor process leaks indicated the following generic ignition
probabilities (Table 5-16).
Table 5-16: Generic Ignition Probabilities
Release Rate Category Release Rate (kg/s) Gas Leak
Probability
Oil Leak
Probability
Minor <1 0.01 0.01
Major 1-50 0.07 0.03
Massive >50 0.30 0.08
Although records review of the Norwegian Oil and gas installations indicated ignition delay
for process leaks whereas the OCB/Technica (1988) revealed that for about 50% of the cases
the ignition was delayed by about 5 minutes or more allowing escape of onsite crew and
drilling personnel.
However, as similar consequences viz. pool fire and jet fires are anticipated from process
leaks as in blow outs, identical risk scenarios have been considered (in terms of oil and gas
release rates) for leak consequence modeling based on professional judgment and analysis of
process leak accident database. Hence, consequence modeling for process leaks/fires will be
similar to that undertaken for well blow outs as discussed in the earlier section (Refer section
5.3.1).

Risk Ranking & Significance = 8 i.e. “Low”
Preventive and Mitigation Measures
The preventive and mitigation measures for process leaks, fires and explosions will be
implemented. Mitigative measures include the following:
Provision for adequate leak and fire detection alarm systems;
Installation of firefighting equipments, portable and fixed.
Potential sources of ignition like welding/hot works, compressors, electrical
equipment, compressors etc. be minimized, as far as practicable;
Proper ventilation be arranged for in hazardous area to allow for inflammable gases to
dissipate, when a release has occurred;
Proper mechanisms like ESDs which can isolate leaks effectively need to be installed,
in high risk process trains.
Effective barriers in the form of blast walls, blast relief panels, etc. be installed to
shield workers from high risk area where explosions may occur.
Strict implementation of permit to work system and hazardous zone classification.
Basic firefighting training to all working on the drilling rig.

Installation of electrical equipment as per the hazardous zone classification.
5.3.3 Non-process fires/explosions
Non-process fires are any fires and explosions that involve material other than hydrocarbons
(e.g. electrical fires, diesel fires, accommodation fires, miscellaneous sources etc.). Most non-
process fires are small incidents which can be managed within the facility using existing
firefighting equipment’s. Such fires have however a higher frequency of occurrence
compared to process fires and explosions as recorded by HSE database and World Offshore
Accident Database (WOAD). Due to the absence of veritable data source recording non-
process fire/explosion incidents for onshore installations the aforesaid databases for upstream
oil and gas sector have been referred in an effort to analyze non-process fire/explosion risks
with respect to the proposed project.
Historically, few fatalities have been reported from non-process fires and most of them have
been successfully managed at the installation level. Based on the WOAD 1996 statistical
report, the average fatality rate for non-process fires is estimated at 10-3 platform year. Again,
these fatalities have already been addressed under risks covered under personal accidents and
need not be considered for fatalities due to non-process fires. However, as they have a higher
probability to occur such incidents may cause inconveniences and come in the way of smooth
operation of the drilling activities. The frequency of occurrence of fires due to possible non-
process accident has listed in the Table 5-17 below:
TABLE 5-17: FREQUENCY OF OCCURRENCE - NON-PROCESS FIRES
Non-Process Accidents Frequency (per year)
Electrical fires 7.0 X 10-2
Diesel fires 9.2 X 10-3
Machinery fires 2.2 X 10-3
Miscellaneous fires 2.1 X 10-3
Source: WOAD
As a result, though the damage potential is low, it is important to take appropriate safeguard
measures to minimize their occurrence. Many of these measures can be implemented through
the stipulation of simple work instructions and procedures.

5.4 DISASTER MANAGEMENT PLAN
5.4.1 Objective
The primary objective of the DMP is to provide a safe, timely, effective and coordinated
response by the onsite Emergency Response Team (ERT), along with the other local and
government agencies/departments to prevent or minimize any major emergencies that may
arise from possible failures/risks viz. blow outs, oil spill, fire & explosion etc. associated with
drilling.
The main objectives of this plan are:
To minimize the risk for human life, environment and common property resources, by
means of an effective and efficient intervention;
Protection of the environment;
Protection of public safety;
To initiate the early and efficient response throughout the utilization of all available
resources.
5.4.2 Purpose
The purpose of the DMP is to effectively manage and control the emergencies occurring
during project operations. This DMP ensures,
Emergency response group is effective & adequate;
Clear roles and responsibilities of key personnel & support groups;
Availability and adequacy of emergency infrastructure & resources; and
Efficient emergency communication
5.4.3 Emergency Classification
Due consideration is given to the severity of potential emergency situation that may arise as a
result of storage tank as discussed in the Quantitative Risk Analysis (QRA) study. Not all
emergency situations call for mobilization of same resources or emergency actions and
therefore, the emergencies are classified into three levels depending on their severity and
potential impact, so that appropriate emergency response procedures can be effectively
implemented by the Emergency/Crisis Management Team. The emergency levels/tiers
defined with respect to this project based on their severity have been discussed in the

operations personnel, who can be called upon 24 hours a day, supported by senior

6.1.3 Flare & Illumination Management Plan
The glare from the flare and illumination not only cause visual impacts but also causes
ecological impacts. These best practices can be adopted for reducing ecological impacts to
animals especially when operating in the migratory birds habitat.
Enclosed Ground Flaring
The elevated flare can be replaced by an enclosed ground flare, such as the enclosed ground
flare. This type of flare eliminates much of the visual impacts of burning produced gas in a
processing facility. Also, the enclosed ground flare will decrease the amount of smoke and
noise compared to the elevated flare
Work Zone Illumination
An oil exploration facility in Maryland has adopted low height (less than 8 m), low-pressure
sodium lamp that are most energy efficient to reduce the ecological impacts (Fure, 2006).
Further, illumination has been provided only in required locations and has placed UV filters
on lamps. Such UV filtered lights have been found to less distractive to migrating birds
(Wiltschko et al. 19938, Poot et al. 20089).
6.1.4 Storm Water Management Plan
Scope
The Storm Water Management Plan (SWMP) refers to the proper management of surface
run-off generated during monsoons for various phases of activities involved in the project.
Purpose
The purpose of Storm Water Management Plan (SWMP) is to ensure prevent and control any
adverse impact of discharge of storm water from the well site and road
widening/strengthening areas to nearby natural drainage channels and community water
bodies. Proper management of storm water runoff will minimize damage to public and
private property, reduce effects of development on land, control stream channel erosion,
pollution and sediment deposition and also reduce local flooding.
Mitigation Measures
Pipe drainages will be provided for diversion roads constructed for the construction of
new bridges and culverts.
Storm water from all longitudinal and cross drainage works will be connected to the
natural drainage courses.

Necessary measures will be undertaken during construction phase to prevent earth and
stone material from blocking cross drainage structures.
Periodic cleaning will be undertaken to cross drainage structures and road drainage
system to maintain uninterrupted storm water flow.
Obstructions that may cause temporary flooding of local drainage channels, during
construction phase will be removed.
Oil traps and oil water separator will be used to separate oil from runoff water
Sediment control measures in the form of silt traps and sedimentation tank will be
provided to treat surface run-off before disposal
6.1.5 Spill Management
A number of chemicals and oil (high speed diesel) will be stored on site, improper handling
or accidents are likely to result in spills which have a potential for contaminating the
environment. Oil would develop and educate the Contractors/personnel working to prevent
such spills and also develop a proper spill response and management plan.
As best practices to avoid/contain any spill oil would ensure:
All chemicals are stored within the designated area. To an extent possible all such
areas would away from drainage channels
The flooring of the area should be impervious (paved or HDPE lining) and bunding to
be provide on all sides of the chemical storage areas
The chemical storage area to be covered to ensure it has the minimum runoff.
All transfers of chemicals to be done with proper care and under the supervision of
the Store supervisor
No oil transfers will occur, unless adequate protection is in place
ONGC’s spill management plan would aim to control the spill to a limited area and take
necessary mitigative actions. The following additional measures will be implemented for spill
management:
Once a spill incident has occurred, identify the chemical involved and check
hazardous property of the chemical from the Material Safety Datasheet (MSDS);
Person wearing required PPE will apply necessary absorbent like saw dust for a liquid
spill to ensure that the spill does not spread over a wide area or reach any surface
water body or drainage channels;
Thereafter, the substance will be properly collected and stored in a separate labeled
container marked “hazardous waste – do not burn”; and dispose in accordance with
Hazardous Waste (Management, Handling & Transboundary Movement) Rules, 2008.

issue of public safety of the villagers, especially children, tea garden workers is an important
concern. During the drilling phase and for the rest of the project activities proper safety
measures will be undertaken both for transportation as well as the other operations. The drill
site would be fenced and gates would be constructed so that the local people are refrained
from straying into the site.
The movement of traffic is also likely to disrupt access conditions of the inhabitants residing
close to the access road. The increase in traffic will have implications on their safety too, as
well as create congestion, potential delays and inconvenience for pedestrians. The mitigative
measures in this regard have been discussed in detail under the Road Safety & Traffic
Management Plan (Section 6.1.5).

During the project tenure there might be some sharing of resources viz. land, water, access
routes etc. by the villagers and the contractor workforce. Prior to the commencement of the
proposed activity, a consultation program will be conducted by ONGC with the target groups
and local authorities. The primary objective of such consultation will be to share with the
concerned villagers/stakeholders the objective of the proposed project associated impacts and
their mitigation. The movement of heavy vehicles and machinery might lead to conditions
like disruption of electric wires and telephone wires in the site area and along transportation
routes. These public utilities will be restored back to normal conditions, at the earliest.
Fencing of the site will lead to in some cases the temporary loss of shortest foot track routes
for the villagers to their agricultural fields. Consultation with villagers will be carried out in
such cases to assist them in finding alternative foot track routes.
Corporate Social Responsibility
From inception of its activities ONGC has taken up various CSR initiatives in and around
ONGC's operational areas for the benefit of the residents as per the CSR Act and Rules,
Govt. of India. ONGC's CSR Vision Statement envisages 2% allocation of its net profit
towards CSR. ONGC also has a CSR Policy. Based on the local area of project, CSR
interventions will be finalized by ONGC. During consultation three key areas for CSR
interventions identified were drinking water, Health and educational services beyond primary
school in some of the villages. ONGC project falls under following villages –Mankora,
Majhguwan Patol, Luhari and Dhauliya kheda nearby Hatta town. During consultation
following needs observed in these villages as given in below
There was lack of health services
Education facility was not adequate like sitting arrangement, electricity, drinking
water, lack of teachers at Mankora Village
Drinking water facilities and irrigation was the main problem in the village, there
were limited
Village approach and entire access road was very poor of Mankora village
Based on the site specific assessments the following activities have been planned under
Enterprise Social Responsibility and Corporate Social Responsibility Programs:
Construction of 2.2 Km pucca road from Damoh-Panna Highway to village
Khajuria via village Luhari. There are four bridges and one culvert which will be
constructed at an approximate cost of Rs.60lakhs. The road will be used by the
villagers also and benefit them in future as well.
Two no of Hand pumps are to be provided in the village Luhari at an approximate
cost of Rs.1.2lakhs, as requested by Gram Sarpanch .
Two nos. of Community Halls (30’x15’) are proposed to be constructed in the
village Luhari at an approximate cost of Rs.8.3lakhs, as requested by Gram Sarpanch
A First Aid Medical kit is proposed to be provided to the in the village Luhari at an
approximate cost of Rs.5000.00, as requested by Gram Sarpanch .

6.1.9 Site Closure Plan
The site closure plan will identify all the activities which would be performed during the
restoration of a well site in case the well is not economically viable and no further use of that
particular well bore is envisaged. Along with the well site the approach road connecting the
well will be restored accordingly. As ONGC would obtain several permission such as tree
cutting (if required), permission from Pollution Control Board and ground water extraction,
the conditions and recommendations mentioned in permission letter would be complied and
consultations with the concerned Govt. Department officials to be made at the time of site
closure and reinstatement.
Chronological inventory of activities which would be performed during the closure of the site
are detailed in this section
The following activities have been considered in the closure plan:
Plugging & Abandonment of well: Close the well head properly to prevent any further
leakage
Decommissioning Phase : Removal of the materials form the site
Waste/mud pit closure and reclamation
Reinstatement Phase: regeneration of the land
Handover Phase : Returning the land to the original owner
Plugging & Abandonment of well
As and when the well will be declared as non productive, plugging of the well will be
performed to close and abandon the well to prevent any leakage of oil or gas.
Decommissioning
The decommissioning phase includes activities dismantling and removal of surface facilities
from the well site and storage in the Material Dumping Area. The activities which are
envisaged during this phase are:
Waste Management: clean up the site and remove all waste materials e.g. HDPE
liners, any waste material etc. The waste will be dumped in the designated area as per
the guidelines of local pollution control board.
Road Restoration: The fill materials should be removed and the site would be
restored.
Waste and mud pit closure and reclamation
Following decommissioning and abandonment of the well site the waste and mud pits will be
subject to closure through onsite burial of solids in accordance with lease and obligations and
with local, state and national regulations. Reclamation of closed pits or any other temporary
EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.
SENES 196 ONGC
retaining pits, including reserve pits, will be carried out within a period of one year from well
closure/abandonment. All such reclamation activities will be carried out based on the climatic
conditions and will be in accordance with Forest Clearance guidelines.
Reinstatement
The reinstatement phase includes all activities for preparation of the Soil for plantation of
trees and agricultural practices at the concerned site.
6.1.10 Training of ONGC Professional
The ONGC professionals would also play an important role in the execution of the work.
They should also be aware of the environmental issues and actions which need to be avoided
to prevent any environmental damage. Pre-drilling environmental awareness and training
sessions would be conducted for the staff to be deployed for the drilling assignment. The
following training sessions could be considered;
Training on Environmental Regulations;
Training on Environmental Monitoring and Quality Checking;
Training on occupational safety management
Training on Industry Best Practices for Environment and Safety
The activities undertaken by these employees would also be constantly reviewed by the
Drilling Manager and Site/Shift Supervisor. Any lapses in adhering to the environment
parameters would be immediately brought to the notice of the ONGC Management and steps
taken to ensure proper training.
The Environmental Management Plan Matrix for the proposed project has been presented in
the Table 6.2.

6.3 ENVIRONMENTAL MONITORING PROGRAM
Monitoring is one of the most important components of a management system. Continuous
monitoring needs to be carried out for regulatory requirements, to monitor the environmental
quality and to determine performance of proposed mitigation measures. Monitoring
indicators have been developed for each of the activity considering the mitigation measures
proposed. Indicators have been developed for ascertaining the environmental quality and
performance of the EMP implementation through Environmental Quality Indicators (EQI’s)
and Environmental Performance Indicators (EPI’s) respectively which focus not only on
quantifying or indexing activity-environment interactions that may potentially impact the
environment but at the same time also help in comparing different components of
environmental quality against previously established baseline values. Monitoring results will
be documented, analyzed and reported internally to Head–HSE of ONGC. Monitoring
requirements have been described in the following Table 6.3. Frequency of monitoring and
responsibility of carrying out the monitoring have also been presented in the table below.

8 Summary & Conclusion
The exploration block VN-ONN-2009/3, which is located in the district of Damoh and
Chhatarpur, is awarded to ONGC through Production Sharing Contract (PSC) for carrying
out onshore exploration in entire block. However, on the basis of seismic survey
interpretation ONGC has identified lead area in Damoh District only. The lead area is devoid
of any forest and ecological sensitive zone. Further, on the basis of seismic survey
interpretation location of exploratory well R-HAT-A has been finalized in Patera Tehsil of
Damoh District. The tentative locations of other 3 exploratory wells are also identified within
lead area. However, these locations would be finalized in later phase of the project after
completion of seismic survey interpretation.
As per provisions of EIA notification 2006, Environmental Clearance is required to obtain
prior to initiate the project. An EIA report is prepared for this exploratory drilling project
based on existing baseline environmental quality data collected for winter season (Jan -Mar)
for the entire block, identification and prediction of significant environmental impacts due to
proposed exploratory drilling process followed by delineation of necessary control measures
are suggested to meet with statutory requirements. The proposed exploratory drilling project
will contribute to economic growth in indirect way and may help in meeting the increasing
demands of oil and gas, if proved economically beneficial for future production.
The proposed project of exploratory drilling intends to make sure whether the allotted oil &
gas license area has the potential for future production of oil and gas in sufficient quantity.
The drilling and associated activities, required to be carried out, will be done in an
environmentally sound manner to the extent possible and will not have any adverse effect on
natural environment of the surrounding area. The analysis indicates all the impacts and risks
predicted from the proposed development to be low to medium magnitude and can be
mitigated with the measures in the formulated management plans.
