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 2011

for a total period of 7 years distributed in two phases, phase –I of 4 years and phase –II

of 3 years durations respectively. At present, seismic data and interpretation for phase –I

is in process and based on interpretation of seismic survey findings in block and

contiguous area, one exploratory location, R-HAT-A in Luhari village, Hatta Tehsil has

been approved for exploration activities. 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-2009/3 block 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.

Regional setting of the Block is shown in Figure 1. 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. The Block location map superimposed on Toposheet is

shown in Figure 2. The accessibility map of this block is shown in Figure 3.

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. The satellite

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 KVA DG Sets. Another 2 sets of DG sets of similar capacity

will be kept as standby all the time for emergency. 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.

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 5m

3/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

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

42.4-44.5 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). Highest night time noise levels were recorded

from Hardua Jamsa village (44.5 dBA).

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 1072 mg/l (at Haruda Jamsa ) 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.

SENES/ESM-D-20525/March 2015 ONGC 10

Surface Water Quality

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 500 µS 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, 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.

EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.

SENES/ESM-D-20525/March 2015 ONGC 11

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 land use map is presented in Figure 5 .

FIGURE 5 : LAND USE LAND COVER MAP OF VN-ONN-2009/3 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

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 (refer Figure 6 ). Zone III is defined as region which

might encounter earthquakes of intensity VII (MSK).

FIGURE 6: SEISMIC ZONE MAP OF INDIA

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

Page 13: 2009/3 Block in Damoh District Madhya Pradesh EXECUTIVE ...

SENES/ESM-D-20525/March 2015 ONGC 13

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, Lantana etc. The herbs and climbers were

recorded from the reserved forest and private forest areas were apamarg, Gokhru,

Xanthium Godhru, Chireta, Bhatkatiya, Gunja, Kiwanch, Bechandi, 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.

SENES/ESM-D-20525/March 2015 ONGC 14

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. It is also headquarters of Hatta. 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 Manpura has 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, NOx, and SO2, 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.

Predicted incremental values for PM10, NOx, SO2, and HC due to DG set operations are

0.25 µg/m3, 1.62µg/m

3, 0.85 µg/m

3 and 0.1 µg/m

3 respectively at a distance of 4km in the

North from the centre of the project site.

Impact on Noise Quality

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

Page 15: 2009/3 Block in Damoh District Madhya Pradesh EXECUTIVE ...

EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.

SENES/ESM-D-20525/March 2015 ONGC 15

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 and ONGC will adopt necessary mitigation measures to address

adverse impacts on biological environment.

EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.

SENES/ESM-D-20525/March 2015 ONGC 16

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.

Page 17: 2009/3 Block in Damoh District Madhya Pradesh EXECUTIVE ...

EIA for Exploratory Drilling in VN-ONN-2009/3 Block, Damoh, M.P.

SENES/ESM-D-20525/March 2015 ONGC 17

Installing acoustic enclosures and muffler on engine exhaust of DG sets to ensure

compliance with generator noise limits specified by CPCB.

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

Use of low toxicity chemicals for preparation of drilling fluid.

Storage of drill cuttings in impervious HDPE lined pits

Wastewater disposal will be done either through solar evaporation or necessary

treatment to comply with CPCB onshore effluent discharge standard for oil and

gas industry.

Hazardous waste (waste and used oil) will be managed in accordance with

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.
