Executive Summary Introduction

ONGC, a Public Sector Undertaking (PSU) of the Government of India, has been instrumental in exploring & developing the rich reserves of hydrocarbons including both crude oil & gas in Assam, that has contributed immensely to the State as well as Country’s oil & gas reserve. ONGC has found high potential oil and gas reserves in the Golaghat and Jorhat districts of Assam. Extending the exploration of these reserves, ONGC proposes drilling in 53 locations in Borholla ML, Mekerong ML, Titabar ML, Golaghat Extn IIA ML, Golaghat Extn IIA (addl) ML, East Lakhibari Extn. ML, Kalyanpur ML located in Jorhat and Golaghat Districts of Assam. These locations will be drilled in non-forest area of each ML and the investment would be approximately Rs 1325 crores in phase wise manner tentatively planned in next few years in these fields. Drilling & development in these locations would augment the production of hydrocarbons in the present scenario of growing demand of oil and gas in the country.

The proposed project is included under activity 1(b)” Offshore and onshore oil and gas exploration, development & production)” specified in Schedule of the EIA Notification dated 14th September 2006 and subsequent amendments & categorized as “A” category project that requires an Environmental Clearance (EC) from the Ministry of Environment, Forests and Climate Change (MoEF&CC). The Terms of Reference (ToR) for the Project have been approved by MoEF&CC vide letter F. No. IA-J-11011/86/2019-IA-II(I) dated 14 Apr 2019.

AECOM India Pvt Ltd., a NABET-QCI accredited firm has been delegated the task of conducting an EIA study and technically assisting ONGC for obtaining environmental clearance from the MoEF&CC. Project Description Block location and Accessibility

The PML Block Borholla ML, Mekerong ML and Titabor ML of Jorhat district; and Golaghat Extn IIA ML, Golaghat Extn IIA (addl) ML, East Lakhibari Extn ML and Kalyanpur ML of Golaghat district. The major roads passing through the PML blocks includes State Highways 32, 33 and 34. Titabor Railway Station is 13 km to the North of Borholla ML. Golaghat, Furkating and Jamguri Railway Stations are 10.16 km (NE), 3.94 km (NE) and 3.08 km (NW) respectively from the East Lakhibari ML. Sarupathar Railway Station is located 2.78 km to the North-Western side of Golaghat Extn IIA (addl) ML . Jorhat Airport is 29.77 km North of Borholla ML Block boundary. Land Requirement

The non-forest PML blocks are located in Jorhat and Golaghat districts of Assam and encompasses within an area of 232.12 sq. km. There would be drilling & development activities in 53 new drilling locations in the seven (7) PML areas, which has been taken on lease. The project proponent does not propose acquisition of permanent land involving residential or built-up area; hence leading to no displacement of people. Therefore, the project does not involve in resettlement and

rehabilitation issues. No forest land would be used for drilling purpose, so forest clearance is not applicable for the proposed project. Pre-Drilling Activity

Before the commencement of the drilling operation, pre-drilling activities involving site selection, land lease, construction/strengthening of approach roads, Construction of drill sites, Rig mobilization and rigging up and Installation of support facilities would be carried out. Drilling operation of Developmental wells Drilling and Testing of well

The drilling process involves construction of a conduit between the surface and the reservoir, for the exploitation of hydrocarbons. The well will be drilled using a standard land rig or a “Mobile Land Rig” with standard water-based drilling fluid treatment system. This rig will be suitable for drilling up to the desired depth of 2200- 3300 meters as planned for the project. The typical configuration of a Drilling Rig is shown in the Figure 6. Drilling is a temporary activity which will continue for about 30-60 days for each well in the block. The rigs are self-contained for all routine jobs. Once the drilling operations are completed, and if sufficient indications of hydrocarbons are noticed while drilling, the well is tested by perforation in the production casing. This normally takes 2-3 days. If the well is found to be a successful hydrocarbon bearing structure, it will be sealed off for future development. Mud system and cuttings

Drilling of wells requires specially formulated muds that creates lubrication and cooling of the drill bit, balances subsurface formation, bring out the drill cuttings from the well bore, have thixotropic property to hold cuttings during non-operations and form thin cake to prevent liquid loss along well bore. Several additives are mixed into the mud system to give the required properties. Water based mud (WBM) will be used to the possible extent. Ingredients of WBM would be Barite, Bentonite, Carboxy Methyl Cellulose Mud Thinner / Conditioner, Resinated Lignite, Non-Weighted Spotting Fluid, Weighted Spotting Fluid, EP Lube, Drilling Detergent, Caustic Soda and Potassium Chloride.

Mud used during the operation will flush out formation cuttings from the well hole. These cuttings will be separated from the drilling mud by thoroughly washing and stored in the HDPE lined pits 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 will be done. The total amount of cuttings produced during the entire drilling period is projected to be about 225 m3. Once the cuttings have been separated, the drilling fluid will be reused or processed after further treatment in a 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 testing and any necessary treatment, to meet the regulatory requirements. The estimated amount of drilling fluid and drilling waste water generated from the whole process would be 700m3 and 15 - 20 m3/day for each well.

Well Testing

Between 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. Logging instruments (sensors) will be attached to the bottom of a wire line and lowered to the bottom of the well. They are slowly brought back, the devices reading different data as they pass each formation and recorded 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 activity. The radioactive source required for well logging activity will be kept in specially designed container. Oil produced during testing activities or during development phases will be stored at the oil pit and will be transferred to the nearest Borholla GGS by oil tankers / pipeline network.

Associated Facilities

There will be other ancillary facilities like drilling mud system, 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.

Well decommissioning On completion of activities, as per the well evaluation, if commercial quantities of hydrocarbons is indicated, then the wells would either be plugged or suspended. In case the quantity of hydrocarbon is not commercially viable the wells will be 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 few wellhead equipment (Blind Flange) left on the surface (Cellar). After the completion of development activities, the well 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. The embanked top soil would be overlain on the de-compacted site with certain moisture conservation measures and seeding of leguminous plant for restoration of soil nutrient level naturally. Utilities and Resource Requirement Water: The total quantity of fresh water required for the project during the site preparation, construction and operation phase is 1000 KLD. During the construction phase, on an average 5 KLD of water would be required for construction of drill pad and 3 KLD for domestic use. The average daily water consumption in the operation phase would be 25 m3/day of which 15m3/day would be used for mud preparation and 10m3/d for domestic purposes (including drinking). Tankers would be deployed from nearby source through contractors. Provision of water storage would be made on-site. Power – The power requirement during the site preparation and construction phase would be met by 3 Nos. of DG Sets (AC-SCR Type) with a diesel consumption of 6 KL/day per well location throughout the project period. The power requirement is for a small period of 8-10 months where, the intensive period lasts only for 45-60 days. It has been anticipated that four (4) nos. DG set unit would be required during the drilling and operation phase.

iii

Labour - It is anticipated that, at any given time, there would be about 30 personnel working on site including technical staff, drilling crew, security staff etc. Project Cost The cost of the proposed project has been estimated would be about INR 1325 Crores. Pollution Sources

Air emissions: Point source air emissions would be generated from DG sets. Fugitive emissions would occur from vehicles involved in the drilling operations, construction activities and from windblown dust from storage and staging areas within the drill site.

Noise & Vibrations: Noise and vibration would be generated due to operation of drilling rig, DG sets and vehicles.

Liquid wastes: There would be generation of 15-20 m3 per day of drilling & wash water and about 2.5 m3 per day of domestic waste water from per well.

Drill cuttings & waste drilling mud: Approximately 225 m3/well of drill cuttings and 700 m3/well of waste drilling mud would be generated. Existing Baseline Environment of the Project Area

Baseline information about the Block was collated by review of other published literature, site surveys, stakeholder interactions and primary monitoring carried out during the period of October 2019 to January 2020 by a NABL Accredited Agency.

Sub-surface Geology The Block is situated in Jorhat and Golaghat district. Geological set-up of both the district is represented by hilly tract and alluvial flood plain of River Brahmaputra. foot hill region is marked by the older terrace deposit. Two terrace surfaces have been identified as the Harmuti and Joyhing surfaces that represent high- and low-level terraces. These terrace deposits are characterised by undulating surface comprising boulders, pebbles of quartzitic and gneissic rocks with fine sand, silt and clay. The alluvial flood plain consists of younger and older alluvial deposits. It represents various sub-features, viz., palaeochannel, swampy/marshy land, river terraces, flood plains, point bars, channel bar and river channel.

Hydrology The Golaghat district is underlain by Quaternary formation followed by Archaean group of rocks. The cumulative thickness of aquifer zones has the tendency to increase towards the north and in the south eastern parts, the thickness reverses considerably. Hydro-geologically, the district is proved to be very potential. Ground water occurs under water table to confined conditions Drainage pattern of Jorhat district is characterized by river Brahmaputra, and its tributaries like south Dhansiri, Bhogdoi and Kakodonga drain the district. The tributaries originate in Naga-Patkai range and flow northward to join the Brahmaputra River, almost at right angles which give rise to subparallel type of drainage.

Hydrogeology and Groundwater Quality The Golaghat district is underlain by Quaternary formation followed by Archaean group of rocks. The cumulative thickness of aquifer zones has the tendency to increase towards the north and in the south eastern parts, the thickness reverses considerably. Hydro-geologically, the district is proved to be very potential. Ground water occurs under water table to confined conditions. Ground water in Jorhat district mainly present in under water table to semi-confined conditions in the near surface conditions and in the deeper horizon, under semi- confined to confined conditions. Depth to water level in the water table zone varies from 0.41 to 3.07 m bgl in the pre-monsoon period and 0.56 to 3.41 m bgl during post-monsoon period. Total of 8 ground water samples have been collected and analysed for parameters as per IS: 10500:2012 standards. Concentrations of various heavy metals like mercury, arsenic, lead, barium, cadmium and selenium were found below detectable limits at all the sampling locations. Presence of Faecal Coliforms has not been observed in any of the water sampled.

Climate and Meteorology The climate of Golaghat and Jorhat District is humid sub-tropical, dominated by the subtropical monsoon which is normally active from April to October with occasional winter showers. At times approach of monsoon is also marked by cyclones in April and May. The plains get flooded. Autumn and winter are dry seasons. The temperature varies from 3°C to 37°C and 04°C to 37°C (October to December) in Golaghat and Jorhat Districts respectively. The yearly rainfall for Golaghat district varied from minimum 1232 mm to maximum 1871 mm with an average rainfall of 1450 mm. The yearly rainfall for Jorhat district varied from minimum 1380 mm to maximum 2112 mm with an average rainfall of 1755 mm

Ambient Air Quality Ambient air quality was monitored at 8 locations (for a period of 3 months – October 2019 to January 2020). The PM10 values of all monitored locations were below were NAAQS value, the P98 values observed would be in the range of - 72.60 – 3 78.00µg/m . The PM2.5, SO2, NOx and NH3, Ni values were in the range of 37.58 – 40.20 µg/m3, 10.32 – 20.48 µg/m3, 11.28 – 23.17 µg/m3 and 0.98 – 1.22 µg/m3 respectively and are well within the National Air Quality Standards (NAAQS). Other parameters namely CO, ozone, ammonia are within NAQS limits. Concentration of other parameters i.e., Arsenic, Lead, HC as methane and Non-methane, Benzo(a)Pyrene (BaP) and VOC were observed to be below detectable limit at all locations

Ambient Noise Levels Noise levels were monitored at 8 locations within the study area. The locations for the noise levels are selected on the basis of sensitive receptors such as health centre, educational centres, market place etc. The day time and night time noise levels were found would be within the permissible standards of 55 and 45 dB respectively during day and night time for rural areas.

Ground Water Quality The pH of water samples ranged from 7.3 to 7.6 and turbidity between 0.24 – 0.72, which is under the permissible limit of 1 NTU. The TDS in the water samples varied from 195 mg/l 335 mg/l, which is in compliance with desirable limit of 500 mg/l. The total alkalinity of the samples varied from 114 - 216 mg/l which is mostly within the

acceptable limit. Total hardness of the samples varied from 104-186 mg/l and was within the desirable limit of 200 mg/l. The concentrations of heavy metals such as Iron, Nickel, Copper, Zinc, Arsenic, chromium, lead was below their corresponding permissible limit. Bacteriological parameters namely E. Coli, Faecal and total coliform were not detected in any of the groundwater samples collected for testing.

Surface Water Quality The pH value ranged between 7.4 to 7.7 and DO concentrations between 7.35 to 7.64, which is higher than the safe criteria of 5 mg/l. The TDS concentrations of all the samples ranged between 34 to 135 mg/l. The BOD and COD ranged between 1.2. to 1.8 mg/l and 7.17 to 12.29 mg/l respectively. The load of total coliform was measured as 17 MPN/100 ml and 120 MPN/100 ml at all the sampling locations. Concentration of Metals like lead (<0.001 mg/l), mercury (<0.001 mg/l), cadmium (<0.001 mg/l), Hexavalent chromium (<0.02 mg/l) were found to be below detection limits for the surface water samples.

Soil Quality The soil sample collected from 7 locations in general indicates slightly acidic to neutral to moderately alkaline nature. The textures of the collected soil samples were found to be sandy loam type to loamy fine sand. The EC values for the soils monitored at the study area range between 99 and 279 µs/cm. The nutrient content of the soil looks satisfactory as per monitored data. Heavy metals such as copper, lead, Nickel and zinc were detectable whereas the concentration of lead and mercury in the soil sample was below detection level in the soil of the study area. However, the monitored values were below the soil remediation intervention values specified in Dutch Soil Remediation Circular. Sodium Absorption Ratio (SAR) - Sodium absorption ratio for the samples varied between 1.7 – 3.0.

Consultation with several group of stake holders, reveal the socio-economic issues like insufficient health care facility nearby, physical infrastructure like road condition and sanitation facilities.

Impact Assessment and Mitigation Measures

Impact on Land use

ONGC would have to take the land for short/long term lease from local panchayat/land owners. In short /long term lease, land will be converted from agricultural land to industrial land. After the completion of the lease period the land will be reinstated. Additionally, necessary measures will be adopted by ONGC through provision of adequate compensation against loss of standing crops. Once the drilling activities are completed, the rig would be dismantled, and the drilled oil will be conveyed through underground pipeline. The procurement of land on lease can lead to moderate impact mainly due to expectations on compensation package. There may be impact on the surrounding land use due to disturbance in the micro drainage pattern of the project area due to construction and drilling activities.

Mitigation Measures • Levelling and grading operations will be undertaken with minimal disturbance to the existing contour, thereby maintaining the general slope of site; • The excavated material from the drill site should be stored (temporarily /permanently) in uncultivated/vacant land and away from any drainage channel. • Provide adequate compensation to landowners against loss of standing crops in accordance to regulatory requirements viz. Petroleum & Mineral Pipelines (PMP) Act, Land Acquisition Act, 1894 (amended in 1984) and Scheduled Tribes and Other Traditional Forest Dwellers Right, 2006.

Impact on Topography & Drainage Potential impact on drainage is primarily anticipated in the form of disruption of natural drainage pattern during site preparation, approach road construction, pipeline construction and well site restoration. These activities may lead to alteration of onsite micro-drainage pattern leading to potential problems of obstruction of natural flow of water. This problem is likely to be further aggravated during the monsoons. Mitigation Measures • Levelling and grading operations will be undertaken with minimal disturbance to the existing contour, thereby maintaining the general slope of site; • Provision of drainage system will be made for surface run-off • Disruption/alteration of micro-watershed drainage pattern will be minimized to the extent possible. • Loss of micro-watershed drainage, if any, is to be compensated through provision of alternate drainage

Impact on Air Quality

Impact There would be impact on the ambient air quality from generation of flue gas containing Sox and NOx from stacks of DG sets & flare stacks and fugitive dusts from construction activities, vehicular movements, material stockyard, etc. he project already embeds control measures like water sprinkling at regular activities, design of DG sets as per statutory requirement and covered storage of materials.

Mitigation Measures • Location of construction materials will be away from nearby worker’s camps; • Proper handling of materials to ensure minimal emission of dust.

vii

To minimise emission from the vehicles, equipment and machinery the following measures would be adopted: • Movement of construction vehicles will be minimised, and minimum speed will be enforced along the access and approach roads; • Black-topping of roads to prevent fugitive emission • All diesel-powered equipment will be regularly maintained, and idling time reduced to minimise emissions; • Low sulphur diesel will be used in diesel powered equipment and best management practices would be adhered to; • Vehicle / equipment air emissions will be controlled by good practice procedures.

Impact on Noise Quality

Potential impact on ambient noise level is anticipated from vehicular movement, operation of construction machinery, access road strengthening during well site preparation and operation of drilling rig, DG sets, pumps and ancillary equipment during drilling operation and early production.

Mitigation Measures • Providing a green buffer at the fence line of the well pad site facing the sensitive receptors to further attenuate the noise propagation beyond the well pad boundary • The DG set would be kept in an acoustic enclosure. • 100 meters buffer area from the boundary of the well pad would be maintained to prevent uncalled disturbances due to noise generations on the sensitive area such as school buildings, primary health center, etc particularly during operation phase. • Periodical monitoring of noise level within 500 mts buffer area around well pad. • Undertaking preventive maintenance of vehicles and machine to reduce noise levels

Impact on surface water quality

Site clearance and stripping of top soil during construction/preparation phase 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. There would also be impact if wastewater generated during construction phase is released without adequate treatment.

Mitigation Measures • Proper treatment of all wastewater and produced water discharges will be made to ensure that they comply with criteria set by the regulatory body (MoEF&CC and SPCB). • Waste mud to be stored in the HDPE lined 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.

viii

• An oil-water separator will be provided at the storm water drainage outlet, to prevent discharge of contaminated run-off. • All chemical and fuel storage areas, process areas will have dykes/bunds around it to prevent escape of contaminated surface run-off into the storm- water drainage system. Impact on ground water quality

Groundwater extraction has not been envisaged for the proposed exploration & development project. However, there would be impact on the groundwater resource due to the drilling activity as there may be contamination in the shallow aquifer, if present near the drill site. Cementing and casing would be done within few hours of drilling. Possibility of contamination of subsurface and unconfined aquifers may happen 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 drilling waste and mud in an open/unpaved pit. However, the toxicity test of the drill cuttings of nearby wells of Assam Arakan-Assam Basin has shown the absence of any hazardous chemicals.

Mitigation Measures Wastewater would be temporarily stored in impervious pits.

Impact on soil quality

Potential impact on soil quality is envisaged in the form of increase in soil erosion and loss of soil fertility resulting from site clearance and top soil stripping during well site preparation. The impact from accidental spillage resulting from storage and handling of mud chemicals is also envisaged.

Mitigation Measures • The top soil will be stored properly; in mound form upto a height of 2m and a slope angle of 30˚ • A jute mat will be over layered 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. • Adopt best practices e.g. use pumps and dispensing nozzle for transfer of fuel, use drip trays etc. • Restricted project activities during monsoon. • Carrying out adequate restoration of soil.

Impact on Roads and Traffic

There would be impact on Roads & traffic due to increased traffic load due to movement of machinery & manpower.

Mitigation Measures • Speed limits would be maintained by vehicles involved in transportation of raw material and drilling rig. • Road safety awareness programs/campaign would be organized in coordination with concerned authorities • Entry of vehicles into the drilling site area is prohibited except for material movement. • Adequate parking would be provided outside the drilling location.

Impact on Terrestrial Ecological environment

The Potential Impacts on the existing floral and faunal diversity may arise due to Vegetation Clearance, Illimitation from Site and Generation of noise.

Mitigation Measures • The working area would always be kept minimum. • For felling of trees prior approval from concerned department would be obtained; • Appropriate shading of lights would be ensured to prevent unwanted scattering. • Plantation of local trees would be undertaken; • Fencing would be done on the camp site to avoid any unfortunate encounter with faunal species. Impact on Aquatic Ecological environment

Potential impact on aquatic floral and faunal diversity is envisaged particularly during Site preparation phase and operation phase. During Monsoon, due to the 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 and rivers unless precautionary measures are adopted.

Mitigation • Proper treatment of all wastewater and produced water and any water discharge from well site would comply with CPCB Discharge Standards for Oil and Gas Industries • Waste mud would be stored in the HDPE lined pit • Drainage and sediment control systems at the well site would be efficiently designed • All chemical and fuel storage areas, process areas would have proper bunds so that contaminated run-off cannot escape into the storm-water drainage system.

Impact on Socio economic environment Influx of population is anticipated in all stages of the project cycle particularly during exploratory drilling. 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. Mitigation • The shortest distance as far as available/feasible would be considered for access road, with additional care to avoid division of land parcels into agriculturally unviable fractions; • The village road identified for accessing proposed project footprints, would be strengthened and widened as per requirement • Appropriate awareness program on grievance redressal mechanism, would be designed and implemented for local community around proposed project footprints;

Occupational Health & Safety Risks The health and safety risks associated with drilling operations may include well kick or blow out, crane failure, fire Hazards and radiation hazard from well logging tool handling and storage.

Mitigation Measures • Blowout preventers would be provided; • Flare pit would be placed at a safe distance from the well head and fuel storage areas; • Fire-fighting measures would be provided. • Periodic onsite surveillance would be conducted so that the workers use the designated PPEs all the time; • Periodic Health surveillance would be conducted of all working personnel • Regular health and safety training would be provided to workers. • Exposure of workers operating near high noise generating sources would be reduced to the extent possible;

Impact on Community Health & Safety Community health and safety of inhabitants residing close to the drilling site is likely to get affected from frequent heavy vehicular movement along village access roads and due to noise from drilling rig operations. The increase in traffic load due to project activities would have implications on their safety too, as well as create congestion, potential delays and inconvenience for pedestrians.

Mitigation Measures • Drilling activities would be under proper fencing • Proper hoardings in English and local language would 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 project activities. • Traffic management plan would be developed and implemented at site. • Proper Onsite & offsite management plan along with Disaster Management Plan (DMP) would be in place to deal with emergencies and contain the impact to minimum extent.

Environment Management and Monitoring Plan

A comprehensive environmental monitoring plan has been developed for the project. Monitoring of ambient air quality, noise levels, soil and groundwater quality, etc. would be carried out by MoEF&CC/NABL/ASPCB recognized laboratories for pre and post drilling operations to assess the effectiveness of the environment management plan and adopt appropriate corrective measures if it found that those are not functioning properly. HSE Policy ONGC is committed to protect the environment as well as health & safety of every individual involved in its operation, and he sustainability of the environment in which it operates. ONGS already has a appropriate environmental management system in line with ISO 14001. ONGC has implemented Integrated HSE management system (QHSE) based on ISO 14001, ISO 9001 and OSHAS 18001 in their existing installation. ONGC would continue to conduct its activities in a professional and effective manner and comply with the legislative requirements and when found non-complaint, would promote creative measures and internal standards for safeguarding of Health, Safety & Environment to a possible extent, for all who may directly or indirectly be affected by any of the activities.

Corporate Environment Responsibility (CER) The company would comply with the Office Memorandum of Government of India dated 1st May 2018 w.r.t. CER and the cost towards CER would be Rs 6.525 crores. EMP Budget The capital cost & recurring expenses for implementation of EMP measures per well would be Rs 15 lakh and Rs 12 lakh respectively.

1. Introduction

India is the third largest consumer of primary energy globally and the demand is expected to double by 2035. India primarily depends on import of petroleum goods for meeting its energy demands and imports about 80% of crude oil demand for the same purpose. As the need of the hour imply, Government of India aims to enhance the indigenous production of oil to reduce the import dependency by 10%. In line with this objective, Oil & Natural gas Company (ONGC) has planned to drill 53 locations in non-forest area in their Mining Lease (ML) Area in Jorhat & Golaghat districts of Assam. 1.1 Identification of the Project & Project proponent ONGC is a Public Sector Undertaking (PSU) of the Government of India, under the administrative control of the Ministry of Petroleum and Natural Gas. It is India's largest oil and gas exploration and Production company with Maharatna Status, contributing around 75 per cent to Indian domestic production with crude oil, natural gas, LPG, NGL, Petrol, HSD etc. as the key products. Along with hydrocarbons, ONGC has expanded its horizon to emerging domains of renewable and other alternative sources of energy. With a market capitalization of over INR 3.5 trillion, it is one of India's most valuable publicly-traded companies. Assam has rich reserves of hydro carbons including both Crude oil and gas. ONGC has been instrumental in exploring & developing these resources that has enormously contributed to the State as well as Country’s oil & gas reserve. ONGC has found high potential oil and gas reserves in the Golaghat and Jorhat districts of Assam. Extending the exploration of these reserves, ONGC proposes drilling in 53 locations in Borholla ML, Mekerong ML, Titabar ML, Golaghat Extn IIA ML, Golaghat Extn IIA (addl) ML, East Lakhibari Extn. ML, Kalyanpur ML that falls within Jorhat and Golaghat District of Assam. These locations will be drilled in non-forest area of each ML and the investment would be approximately Rs 1325 crores in phase wise manner tentatively planned in next few years in these fields. It is expected that drilling of these locations will lead to augmentation in the production of hydrocarbons in the present scenario of growing demand of oil and gas in the country 1.2 Brief Details of The Project The project involves drilling in the non-forest area of Borholla ML, Titabor ML, Mekrang ML, Golaghat Extn IIA (addl) ML, Golaghat Extn IIA ML, East Lakhibari Extn. ML and Kalyanpur ML covering respectively 32.12sq. Km, 10 Sq.Km, 16 Sq. Km, 61 Sq. Km, 24 Sq. Km, 49 Sq. Km and 40 Sq. Km of South Assam Shelf Block in Jorhat and Golaghat districts, Assam as shown below

The envisaged cumulative production in terms of O+OEG in next 15-16 years is in the tune of 1.76 MMt. Total estimated cost of the project is Rs. 1325 Cr. 1.3 Importance of the Project

India is the third largest primary energy consumer globally and the demand is expected to double to 1,516 Mtoe by 2035 from 753.7 Mtoe in 2017. India primarily depends on import of petroleum goods for meeting its energy demands and imports about 80% of crude oil demand for the same purpose. For the last 3 years including the last financial year of 2018-19, the crude oil production hovers around 35 MT. India provisionally imported 207.3 million tonne of crude oil in 2018-19, down from 220.4 million tonne in the previous financial year. In order to bridge the rising demand-supply gap, cut import dependency and gradually defuse the socio-political factors due to external sourcing, it is imperative to boost exploration & appraisal of hydrocarbons, mainly oil & gas. In view of this, ONGC proposes development of oil and gas reserves by development drilling of 53 wells in Golaghat and Jorhat districts of Assam. This project will reduce the dependency of India on import of oil by augmenting the indigenous production and would have immense benefit for the economic scenario of the Country. There would be holistic development in the socio-economic status as well as infrastructure of the region in terms of employment opportunities and improved physical & social infrastructure. 1.4 Objective of the EIA Study The proposed project is included under activity 1(b)” Offshore and onshore oil and gas exploration, development & production)” specified in Schedule of the EIA Notification dated 14th September 2006 and subsequent amendments & categorized as “A” category project that requires an Environmental Clearance (EC) from the Ministry of Environment, Forests and Climate Change (MoEF&CC).

2.6 Pre-Drilling Activity Drilling of 53 development wells is proposed to be in operation in seven (7) non- forest PMLs located in the districts of Jorhat and Golaghat districts. To extract the entrapped hydrocarbon from the reserve, the drilling operation would be carried for a depth of 2200- 3300 m and the estimated drilling period is 2 to 3 months. Before the commencement of the drilling operation, pre-drilling activities are mentioned in this section: • Site Selection • Land Lease • Construction of approach road • Construction of drill sites • Rig mobilization and rigging up • Installation of support facility 2.6.1 Site Selection

The foremost requirement for site selection is the detailed study of the geological and exploratory history of the area under consideration, to determine the potential presence of oil and gas in the region. The proposed development wells have been identified and selected by ONGC, based on the available geological data. After conducting the reconnaissance survey, suitable drilling locations were selected based on the following factors: Geological factors • Terrain type to ensure unhindered flow of rain / flood water and if necessary adequate erosion control measures would be provided; • Ensure natural drainage channels are avoided, or drainage channels rerouted; • Ease of access based on the topographical features. Environmental considerations • Away from dense human habitat; • Easy access road to reach the targeted area. Technical suitability

2.6.2 Land Procurement

The present project proposes 53 new drilling locations comprises of development wells in the seven (7) PML areas, which has earlier been taken on lease (Refer Section 2.1 for tenure of lease for each PML). The project proponent does not propose acquisition of permanent land involving residential or built-up area; hence leading to no displacement of people. Therefore, the project does not involve in resettlement and rehabilitation issues.

2.6.3 Road Construction

Approach roads within the PMLs is required for the movement of personnel, drilling rig and associated equipment and machineries. Besides the construction of new approach roads, existing approach roads would be used as the proposed drilling operation would be undertaken in the existing PMLs areas. The approach road construction work would be carried out in one or all the following stages:

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 25

• The existing approach roads close to the drill sites would be preferably used • Upgradation and strengthening of the existing roads would be undertaken wherever necessary. The existing roads would be developed by widening or if necessitated, the road would be strengthened by addition of base material to increase support and the old culverts, pipes, etc. would be replaced and strengthened. • Construction of new approach roads would be undertaken to connect the existing roads with the drill sites. In case any stream crosses the sites, suitable culverts or bailey bridge construction would be facilitated. During the construction of approach roads, it would be ensured that felling of trees is avoided. Otherwise permission would be taken from concerned department.

2.6.4 Preparation for Drill Site Construction

The development of access to the drill sites will lead to initiation of site preparation activities, facilitating the operation of drilling rig. The sub-activities of the site preparation are discussed in this section. Felling of Tree: In case of felling of trees, permission from the designated authority would be taken. Fencing: The proposed well site would be duly fenced to a height of about 2 m, using chain links and barbed wires, to restrict unlawful entry into the site. Top Soil Scraping: The depth of the top soil of the proposed drill site would be firstly gauged and then the excess depth (0.2 to 0.5 m) and loose top soil would be scraped by using mechanical means like backhoe and subsequently stored in a designated top soil storage site for future use (site reclamation and restoration; or for site filling purposes). Construction of Drilling Platform: Once the top soil removal process has been accomplished with minimum vegetation clearance, initially the drilling site would be elevated to about 2.0 m from the existing ground level, based on local topography and High Flood Level (HFL). The land would be elevated by filling with earth taken from the authorized borrow pits. Elevation will be subsequently be followed by levelling and compaction of the drill site with motor graders or pneumatic tyre rollers or vibratory compactor (depending on the type of soil). Excavation of Pits: Fill material requirement during elevation is mostly met from the excavated material during excavation of pits. Pits will be required for storage of mud, drill cutting, waste water, formation water, etc. A backhoe will be used for all on-site excavation and cutting activities (construction of pits). The following pits to be excavated within the well site are as follows: • Construction of cellar pit for installation of well head and BOP. • Construction of 1 no. impervious HDPE lined pit of dimension 30’ X 33’ X 5’ at well site for temporary storage and disposal of spent drilling mud and cuttings • Construction of 3 nos. impervious HDPE lined waste pit of dimension 30’X 33’X 5’, 38’X 33’X 5’, 23’X 20’X 5’ for temporary storage and disposal of rig wash water. • Construction of 1 no. Oil pit of dimension 3’X 3’ X 4’ to contain the oil which may generated during well testing.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 26

• Construction of septic tanks and soak pits to dispose the domestic wastewater at the drill site.

Construction of Bunds & Storm Water Drains: The soil excavated from the pits would be used to build a raised bund /embankment bordering the periphery of the drill site. Before the bund construction, a storm water drain is constructed, as per the topographic requirement. Oil-water separator and silt-trap would be constructed at one end of the storm water drain. Construction of Drill Pad: A flat rectangular/square drilling pad would be developed at site to facilitate drilling and testing of hydrocarbons. Cast-in-situ Reinforced Cement Concrete (RCC) would be used for the construction of the foundation for a platform facilitating the drill pad and associated heavy equipment or machinery. During the site construction minimum removal of tree cover will take place and the existing trees would be retained to the maximum extent possible. All efforts would be made during the design of the drill pad to prevent felling of any mature trees and to station the rig equipment around them. Typical layout of the drill pad is shown in figure 2-6.

Rig Mobilization and Rigging Up The site preparation process will be followed by the rig building process. This process will involve the transport of rig and auxiliary equipment, assembling of various rig parts and equipment to drill a well. The rig including auxiliary equipment and camp facilities would be transported by trailers. After the drilling rig is assembled, thorough rig inspection would 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. Well spudding marks, the beginning of the drilling process, by removing the rock, dirt and other sedimentary materials with drill bit. The Cellar Pit (top-hole section) will be drilled to a desired depth based on well design. After drilling the Cellar Pit, it will be cased with a pipe and this process is called “Casing”. Casing provides support to hole wall and secures the 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 by oil well cement with some additives like Retarder (R-53) and Friction reducers (FR – 22). Total requirement of the cement would be 100 metric ton/well. Casing details is provided in table 2-1.

Table 2-1. Casing details for vertical/inclined wells Length of the drill hole Hole size Casing size Upto 550 m 17.5 inches 13.37 inches Upto 1950 m 12.25 inches 9.62 inches Upto final depth 8.5 inches 5.5 inches Source: ONGC This process of drilling and casing the hole section continues until the final well depth (2200- 3300m) 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. 2.7 Drilling Operation of Developmental Wells

2.7.1 Drilling and testing of well

The drilling process involves construction of a conduit between the surface and the reservoir, for the exploitation of hydrocarbons. The well will be drilled using a standard land rig or a “Mobile Land Rig” with standard water-based drilling fluid treatment system (Oil based mud would not be used). This rig will be suitable for drilling up to the desired depth of 2200-3300 meters as planned for the project. The typical configuration of a Drilling Rig is shown in the Figure 2-7. Drilling is a temporary activity which will continue for about 40-45 days for each well in the block. The rigs are self-contained for all routine jobs. Once the drilling operations are completed, and if sufficient indications of hydrocarbons are noticed while drilling, the well is tested by perforation in the production casing. This normally takes 2-3 days. If the well is found to be a successful hydrocarbon bearing structure, it will be sealed off for future development, if any.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 29

Figure 2-7: Typical drilling Rig configuration

Additionally, there will be other ancillary facilities like drilling mud system, 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.

2.7.2 Mud system and Cuttings

During drilling process, 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.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 30

Drilling Mud

Drilling of wells requires specially formulated muds which basically comprise inert earth materials like bentonite, barite in water with several additives to give mud weight, fluidity and filter cake characteristics while drilling. The drilling muds have several functions like lubrication and cooling of the drill bit, balancing subsurface formation, bringing out the drill cuttings from the well bore, thixotropic property to hold cuttings during non-operations, formation of thin cake to prevent liquid loss along well bore etc. Several additives are mixed into the mud system to give the required properties. Water based mud will be used to the possible extent in exploratory drilling but use of synthetic based mud may be required due to complexities associated with the geological formations and associated hole stability problems but oil based mud would not be used. The constituents of water-based mud (WBM) are given in Table 2.2. The special additives and their functions in WBM are shown in Table 2.3.

Source: ONGC Drill Cuttings Mud used during the operation will flush out formation cuttings from the well hole. These cuttings will be separated from the drilling mud by thoroughly washing. Cuttings will then be stored in the HDPE lined pits 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 will be finalized by ONGC. The total amount of cuttings produced during the entire drilling period is projected to be about 225 m3 from each well site. Once the cuttings have been separated, the drilling fluid will be reused or processed after further treatment in a 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 testing and any necessary treatment, to meet the regulatory requirements. The estimated amount of drilling fluid and drilling waste water generated from the whole process would be 700m3 and 15 - 20 m3/day for each well. The whole process by which the drilling fluid will be reused during the drilling operation is commonly known as a “closed loop system.” This system is ideal for drilling operations in sensitive environments as it cuts down immensely on the total water consumption for the formulation of drilling mud and also saves on the consumption of chemicals. Figure 2-8 shows the schematic layout of the drilling waste management. Figure 2-9 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.

2.7.3 Well Testing

2.7.4 Transport of Produced Oil / Gas

Oil produced during testing activities or during development phases will be stored at the oil pit and will be transferred to the nearest Borholla GGS by oil tankers / pipeline network. 2.8 Well Decommissioning

2.8.1 Well Abandonment

On completion of activities, as per the well evaluation, if commercial quantities of hydrocarbons is indicated, then the wells would either be plugged or suspended. In case the quantity of hydrocarbon is not commercially viable the wells will be 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 few wellhead equipment (Blind Flange) left on the surface (Cellar). After the completion of development activities, the well 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.

2.8.2 Site Closure and Decommissioning

After completion of the drilling activity, partial de-mobilisation of the drilling rig and associated infrastructure will be initiated if ONGC does not strike oil after drilling at the required depth. As discussed earlier, well testing may be carried out immediately after the drilling is completed or about 3 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 equipment and the residential camp, and transporting it out of the project area. It is expected that demobilization phase will last about 10-15 days and will involve the trucking away of materials, equipment and other materials from site to bring it back to original condition. It is estimated that about 60 truckloads would 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 would be cut off to a minimum depth of 3 m (10 ft) below ground level.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 34

• All concrete structures will be broken up, and the debris would be disposed as per the regulatory requirements. • Drill cuttings and drill mud will be treated as per G.S.R 546 (E) dated 30th August 2005 to render them harmless. • Drilling wastewater including drill cuttings wash water shall be collected in impervious HDPE lined disposal pit, evaporated and treated and shall comply with the S No. 72, Schedule I-Standards for Emission or Discharge of Environmental Pollutants from Offshore Oil and Gas industry. • All other waste products, solid and liquid, would be disposed off in accordance with the requirements of the EIA as specified in later sections and would be treated to render them harmless as per Sl.No.72, Schedule I – Standards for Emission or Discharge of Environmental Pollutants from Oil Drilling Gas Extraction Industries. • All fencing and access gates would be removed. • All pits whose contents would 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.

2.8.3 Site Restoration

After the completion of production activities, all abandoned drill sites would be restored back to its near original condition. After decommissioning of site, it will be de-compacted, and the embanked top soil would be overlain on the de-compacted site with certain moisture conservation measures and seeding of leguminous plant for restoration of soil nutrient level naturally. 2.9 Utilities and Resource Requirements

2.9.1 Power Supply

The power requirement during the site preparation and construction phase would be met by 3 Nos. of DG Sets (AC-SCR Type) with a diesel consumption of 6 KL/day per well location throughout the project period. The power requirement is for a small period of 8-10 months where, the intensive period lasts only for 45-60 days. It has been anticipated that two (2) nos. DG set unit would be required during the drilling and operation phase. Although the drilling operations will be continuous, the power requirement will vary depending on the activities being carried out. One or Two units would be in operation at a time depending on the load requirement and one unit will always be in standby. The exhaust stacks of the DG sets are likely to vent the emissions and only low sulphur (<0.05%) HSD (Euro-III) would be used. The power requirement at different stages of activities is given in Table 2.4.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 35

Table 2-4. Power requirement for Development Wells

Activity Specification of DG Set Site preparation 1 Drilling operations 3 operating and 1 standby Lighting and other power requirement 1 Drill site accommodation 1 Source: ONGC Fuel Consumption, Supply and Storage The fuel consumption would be mainly diesel, used by rig, various equipment, and vehicles operating to transport goods and supplies to the site. During the drilling phase, 6 KLD of Diesel would be required. It is estimated that about 1-1.5 KLD diesel per day would be required to power the off-road construction equipment and vehicles during the site preparation phase. Out of this, a major part, about 85% will be consumed by the rig (including the DG sets) and about 15% will be required for the campsite. Fuel would be supplied onsite by local supplier through mobile tankers. Fuel in excess approximately 42 KL (7 days reserve) would be stored at onsite storage facility as per Petroleum Rules, 2002. The diesel storage area would be paved and would have bund walls and there would be provision of shed. In case the storage exceeds the threshold, limits specified in the Petroleum Rules, 2002, ONGC will comply with the relevant provision of such rules.

2.9.2 Water Requirements

The total quantity of fresh water required for the project during the site preparation, construction and operation phase is 1000 KLD. During the construction phase, on an average 5 KLD of water would be required for construction of drill pad and 3 KLD for domestic use. During the drilling and well testing phase, majority of water requirement would be utilized for preparation of drill mud; and a minor portion of total water is required for domestic use and washing. On an average the daily water consumption in the operation phase would be 25 m3/day of which 15m3/day would be used for mud preparation and 10m3/d for domestic purposes (including drinking). The water requirement per well during the drilling period is tabulated below. The Table 2-5. Water Requirement per Well Site

The water balance diagram showing water requirement for various uses is presented below:

Figure 2-10: Water Balance Diagram

2.9.3 Manpower / Employment

The drilling rig will be operated by approx. 30 persons on the rig at anytime. The manpower would be operating in two shifts with continuous operations on the rig. This would include technical experts (including experts) responsible for various drilling operations and some local workmen would be hired from nearby villages for the entire project duration. Technical staff would be housed in the drilling camp site, which will be adequately supported by facilities like kitchen, wash rooms, laundry, etc.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 37

2.9.4 Chemical Storage

The drilling rig will have normal storage facilities for fuel oil, required chemicals and the necessary tubulars and equipment. The storage places will be clearly marked with safe operating facilities and practices. 2.10 Pollution Sources and Characterization

2.10.1 Noise and vibration

Noise would be emitted from drill site in all the phases of the project life including site preparation, drilling and decommissioning phases. Noise during the site preparatory phase would primarily be contributed by heavy construction machinery operating on site. The major noise generating activities is during drilling, testing and operation of rotary drilling equipment as part of rig, diesel engines for power generation, mud pumps and vehicle movement. As the drilling activity is a continuous process, part of the noise associated with the functioning of the rig and ancillaries would be generated throughout day and night. Average noise emission ranges for different types of construction machineries are provided in Table 2.6 and Table 2.7 provides equivalent noise levels for drilling rig and associated equipment.

2.10.2 Air Emission

Air emission from point sources expected from the development drill site, from combustion of diesel in the diesel engines and in the power generators. The principal pollutants would comprise of Particulate Matter (PM), Sulphur and Nitrogen Dioxides (SO2 and NO2) and other Hydrocarbons (HC). The quantity of diesel consumed during drilling will be in order of 6 KL /day/drilling site. Additionally, the flaring and burning of oil during the testing of well and from GGS 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. Additionally, there will be re-entrainment of dust from the approach road leading to the site mainly during the dry season.

2.10.3 Waste Water Generation, Treatment and Disposal

During the drilling phase the waste water generated due to rig washing and dewatering of spent mud and washing of drill cuttings is 1000 m3 for each well site (approximately 15 – 20 m3/ day). Effluents from, 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 primarily depend on the type and composition of drill 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 (constructed at the drilling site). This effluent generated will be treated, reused and recycled. To ensure that effluent from the project comply with the waste water discharge standards as mentioned in the S No. 72 A (ii) Schedule I Standards for Emission or Discharge of Environmental Pollutants from Onshore Oil Drilling and Gas Extraction Industry of CPCB, a mobile Effluent Treatment Plant will be installed. The plant would be capable of handling 15-20 m3/day of drilling effluents. Domestic waste water generated (about 2.5 m3 per day for the drilling camp) will be treated through a soak pit/septic tank arrangement. Oily sludge would be collected and disposed by bio remediation. The quantity of the liquid wastes, their characteristics and anticipated disposal methods are given in Table 2.8 Table 2-8. Liquid Waste Generated during Drilling and their Disposal

Loss of well control / blow-out, fire, explosion and oil spills are the major potential hazards associated with drilling of oil and gas. Effective response plans to foreseeable emergencies will be developed by ONGC and communicated to the project teams. A risk assessment would be carried out as part of this EIA and would also contribute towards identification of hazards, risks and formulating management plans for emergency response, blowout, oil spills. 2.12 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 would 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 development drilling projects in the non-forest PML blocks through the DMS. The HSE Policy, ONGC is presented in Chapter 9.

3. Baseline of the Environment

This chapter describes the existing baseline environmental settings in study area and its immediate surroundings. This includes the physical environment comprising air, water and land components, the biological environment, and socio-economic environment. Attributes of the physical environment like air, water, soil quality and noise level in the surrounding area were assessed primarily through monitoring and analysis of samples collected from field. Baseline monitoring has been carried out during October to December 2019. Information about topography, geology, hydrology prevailing natural hazards risks like floods, earthquakes etc. have been collected from different available literatures and information from various 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 literatures. The socio-economic environment has been studied through consultations with various stakeholders in the villages within the study area. Additionally, socio-economic data have been obtained from the Census of India 2011 report 3.1 Study area The study area for determination of environmental, biological and social baseline is the entire area encompassing the seven (7) PMLs and 10km radius area from the PML boundaries. The Drilling locations are located mostly in Golaghat district and some locations in Jorhat district of Assam.

The entire study area is covered by SoI Toposheet no G46K/1, G46K/5 and G46 K/9. The hydrocarbon Blocks lie between 26o48’N to 27o00‘N Latitude and 94o10’E to 94o36’E longitude. The study area represents flat to moderately undulating terrain with average ground elevation about 100 amsl. 3.2 Topography

Golaghat District

Physiographically, the district of Golaghat shows a monotonous plain topography towards north and southeast, while the southwestern part of the area represents an undulating topography (Ground Water Information Booklet 2008). The general elevation of the elevated area is around 100 meters amsl and low lying areas show altitude about 80 m amsl (Ground Water Information Booklet 2008). Maximum height of about 128 m above MSL is observed in the southern parts of the district, where it merges with the hills of the Nagaland as well as Karbi-Anglong district of Assam. The slope of the district is towards north east from south.

Jorhat District

The topography of Jorhat district is broadly classified into five types of land forms: a. The flood plain of the Brahmaputra River in the north b. The central upland area covering younger alluvial formations c. The central upland area covering older alluvial formations

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 43

d. The southern undulating hill area running along the Naga-Patkai range covering the piedmont plain e. Structural hills. The elevation of the flood plain area varies from 80 to 90 m, central upland area 95 to 110 m amsl, hills in the southern and eastern parts of the district up to 312 m amsl. The general trend of the hills is NE-SW and at places to N-S. The average elevation is about 100 amsl. The general topography of the area in which the seven (7) PML Blocks are located is plain. The elevation of the area ranges from 16 – 100 m above the mean sea level. Elevation map of the block is presented in Figure 3-1.

3.3 Geology Assam possesses a unique geomorphic environment with plain areas, dissected hills of the South Indian plateau system and with the Himalayas all around its north, north east and east. As per plate tectonics, it is the eastern most projection of the Indian plateau where it is thrusting underneath the Eurasian plate thereby creating a subduction zone geologically (Syed & Bright). Hence the extreme geostatic pressures exerted on the landmass during the creation of the Himalayas have resulted in Assam having large areas of sedimentary deposits leading to formation of huge oil reserves. Geomorphologically, the younger alluvial plain occupies major part of the Borholla ML and small scattered parts are occupied by older alluvial plains. The vast alluvial plains of Brahmaputra valley occupy most of the North Assam including Jorhat, and Golaghat districts. Out of the six agro-climatic zones in Assam, the two districts lie in the Upper Brahmaputra Valley (NAEB). The oil and gas in Upper Assam till 1980s were found in the Barail Group of Upper Eocene to Lower Oligocene age and the Tipam Group of Upper Miocene age. However, during the last decade oil and gas accumulations have been discovered within the Langpar and Lakadong formations of Paleocene to Lower Eocene age. In the Khoraghat and Nambar fields situated in southeastern part of the Dhansiri Valley, oil occurs in the Bokabil Formation (Middle Miocene) which is not developed towards north in the Brahmaputra valley. In the Borholla oil field, oil occurs in fractured granitic basement rock of Precambrian age (DGH India, 2010). The district of Jorhat is bounded by the Naga-Patkai range at the south, Golaghat district on the west and in the south east by the Wokha and Mokokchung districts of Nagaland. The district can be divided into five major parts, viz. flood plain of Brahmaputra river in the north, central upland area consists of younger alluvial formations, central upland area with older alluvial formation, southern undulating hill area adjacent with Naga Patkai range. The area is underlain by unconsolidated alluvial sediments of the Quaternary age, which can be differentiated into i) Older and ii) Younger alluvium. The Older alluvium present at the upland areas with sediments of oxidized and relatively compact nature, while the Younger alluvium occurs along the low-lying tracts of the area along the river courses (Plate II). The southern part of the area, adjacent to the Naga hill range is occupied by surficial blanket of clay, belonging to Younger alluvium and probably has been derived from the adjacent hills which are composed of the rocks of Tertiary age. The altitude of the hills in the southern and eastern parts of the district ranges up to 312 m amsl. The mighty Brahmaputra and its important tributaries like south Dhansiri, Bhogdoi and Kakodonga are the main drainage present in the district. Majuli is situated in the northern part of Jorhat district. Titabor is situated at the southern part of Jorhat district. Geologically the district of Golaghat is underlain by Quaternary formation consisting of younger and older alluvial deposits of various grades of sand, pebbles, cobbles, gravel and clay, followed by Archaean group of rocks. While younger alluvium occurs in major parts in the north of NH-37, that passes in the east-west direction in the district, older alluvial deposits occur mainly towards southern parts of the NH-37. The hard crystalline of Archaean age covers extreme southern boundary of the district

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 46

merging with Karbi-Anglong district. The rock types are granite, granite gneiss and quartzite. 3.4 Hydrogeology

Golaghat District

As per the report of CGWB (2013), Sub-surface geology as evidenced from available data infers that the potential aquifer pertaining to Quaternary formation exist down to the explored depth of 300 m. The cumulative thickness of aquifer zones has the tendency to increase towards the north and in the south-eastern parts, the thickness reverses considerably.

Hydrogeologically, the district of Golaghat has major potential. Ground water occurs under water table to confined conditions. Depth to water level in major parts of the district varies from 2 to 5 m. Depth to water level increases in the extreme southern and southwestern parts close to hills and generally rests within 5 to 7 m. The movement of ground water is from south to north. The water level trend shows that there is gradual rising of water level in the district.

CGWB has constructed 14 exploratory tube wells in the district and it is seen from these wells that three to nine prolific aquifer system exist in the district. Deep tube wells constructed down to maximum depth of 250 m give variable discharge from 26 to 216 m3/hr for draw down within 13 m. Transmissivity and permeability values ranges between 415 to 500 m2/d and 7 to 82 m/day respectively. Hydrogeological map for the Golaghat Extn II A ML, Golaghat Extension II A (addtl) ML, East Lakhibari, Kalyanpur ML and part of Titabor ML and Mekarang MLs are located in the Golaghat district is given in Figure 3-2.

Jorhat District Ground water in Jorhat district is present under water table to semi-confined conditions in the near surface conditions and in the deeper horizon, under semi- confined to confined conditions. Depth to water level in the water table zone varies from 0.41 to 3.07 m bgl in the pre-monsoon period and 0.56 to 3.41 m bgl during post-monsoon period. As per the report of CGWB of Jorhat district, there are about five to six aquifer systems with limited thickness exist within the depth range of 400 m in the vicinity of Brahmaputra River. In the southern region, the aquifer system fades out due to mixing of finer particles of sand and clay and the thickness of the aquifer system decreases. Wide variation in the thickness of aquifer have been observed throughout the district. While in the north eastern and north western parts, the thickness of the aquifer increases along with existence of clear sand beds, the thickness of the clay beds increases southwards i.e. towards Titabar where it attains a maximum thickness of 103 m. Throughout the district, varied thickness of clay beds overlying and underlying the aquifer system exist. Hydrogeological map of Jorhat district is given in Figure 13. CGWB has carried out exploratory drilling in18 wells in Jorhat district, out of which, three wells are abandoned, and thirteen wells are under operation the range of drilling depth varies from 79.72 to 457.30 m bgl with the discharge of 8 to 211.44 m3/ hr. Low duty shallow tube wells have been constructed in the district. The yield of the tube wells varies from 30 to 35 m3/ hr and it irrigates about 3.5 ha. The hydrogeological map of Borholla ML, Titabor Ml and Mekrang ML located in Jorhat district is shown in the Figure 3-3.

3.5 Ground Water Resources As per ground water resource estimation (GEC 1997 Report, i.e. Ground Water Level Fluctuation and Rainfall infiltration factor Method), the net ground water availability in Jorhat district estimated in the year 2009 is 1273.71mcm, existing gross ground water draft 171.09 mcm and the stages of development are 13% only. Future provision for domestic and Industrial use is 34.65 mcm and for Irrigation use is 1093.68mcm. The net ground water availability in Golaghat district estimated in the year 2009 is 1316.24. mcm, existing gross ground water draft 22.43 mcm and the stages of development are 17% only. Future provision for domestic and Industrial use is 31.39 mcm and for Irrigation use is 1087.34 mcm. The stages of ground water development are 13% & 17%, which falls under the safe category and are expected to stay in this category as the long-term water level trend does not show any major change. 3.6 Drainage The drainage pattern of Jorhat district is characterized by Brahmaputra and its tributaries like south Dhansiri, Bhogdoi and Kakodonga. The tributaries originate in Naga-Patkai range and flow northward to join the Brahmaputra River, almost at right angles that gives rise to subparallel type of drainage. These tributaries retain only meager base flow during the dry winter months. The nature of flow of these rivers and streams are highly meandering and abrupt changes in courses of these rivers, possibly due to heavy siltation and epiorogenic movements, cause the flood in the district. The major drainage system of Golaghat district consists of Brahmaputra River and Dhansiri, Galabil, Desoi, Kakodanga Rivers. The River Brahmaputra flowing in east- west direction in the extreme northern parts of the district and its tributaries flowing in north direction, control the entire drainage system of the district. Other rivers have meandering courses with abandoned channels in the form of bils and ox-bow lakes along their courses. Dhansiri River, one of the important tributaries of Brahmaputra River, is a tidal river and are vulnerable to flooding. Drainage map is provided in Figure 3-4 below.

3.7 Vulnerability of the Site Vulnerability of a site is assessed by its potential to be affected by natural hazards. A natural hazard or disaster during the project life cycle has the potential to cause significant adverse impact to its operation as well as to surrounding environmental including its socio-economic scenario of the region. Assam is prone to multi-hazards like floods, earthquake, extreme winds, storms, floods and landslide. Hence, it is crucial to address the vulnerability of the site for assessing the potential consequences and during development of emergency preparedness & disaster management plan.

3.7.1 Seismicity According to the study of Assam state Disaster Management Authority, as per the plate tectonics, Assam is in the eastern most projection of the Indian Plate, where the plate is thrusting underneath the Eurasian Plate creating a subduction zone and the Himalayas. As per the Global Seismic hazard Assessment Program (GSHAP) DATA the entire state of Assam falls in the region of high to very high seismic zone. As per the 2002 Bureau of Indian Standards (BIS) map, this state also falls in Zone V having probability of earthquake with magnitude more than 8 in Richter scale. Historically, parts of this state have experienced seismic activity greater than 6.0, in Richter scale. The State has experienced two major earthquakes in the year 1897 and 1950 with intensities of 8.7 and 8.5 on the Richter scales respectively. The seismic hazard map of the PML blocks is presented in Figure 3-5.

3.7.2 Floods There have been occurrences of flood almost every year in Assam. River Brahmaputra, the main drainage channel of the region, has a total catchment area of 5,80,000 sq km in Tibet, Bhutan, India and Bangladesh. The river flows for length of 918 km in India of which 720 km flows through the plains of Assam. There are about 20 major tributaries of Brahmaputra on its North Bank and about 30 on its South bank. The heavy precipitation is caused by South West Monsoon in the months of May to September. The causes of flood in Jorhat District are due to excessive rainfall in Assam, Arunachal Pradesh & Nagaland and melting of snow at Tibet etc. The rivers collect enormous quantity of silt and raise the levels of the river beds that cannot be contained, thereby overflowing through their catchment area. The main flood prone areas in the district are Jorhat and Titabor sub division. The district of Golaghat district is extremely prone to river bank erosion and flood because of various hydro-meteorological and topographical characteristics of the basin in which it is situated. Dhansiri, the main river of Golaghat district has caused re-current and extensive flooding and bank erosion. Villages under Bokakhat, Dergaon, Khumtai, Golaghat & Morongi that are near to river Brahmaputra & Dhansiri river are especially vulnerable to floods. As per the Vulnerability Atlas of India, BMTPC (2006), about 16.7% of land area is flood prone in Assam, and 12.5% of Jorhat and 36.4% of Golaghat are estimated to be flood prone. The flood hazard map of the seven PMLs is presented in Figure 3-6.

3.7.3 River Bank Erosion Riverbank erosion is a serious issue in Assam that leads to reduction of land mass and eventual washing away of protecting embankments. The major rivers causing erosion are Brahmaputra, Dhansiri, Kakodobga and Ghiladhari. Impacts of riverbank erosion extend to loss of fertile land, loss of people & domestic animals and loss of productive land. Total area eroded from 1954 till date is approximately 386476 Hectares which means that about 7% of the land in the state's 17 riverine districts has been lost due to river erosion in the last 50 years. 3.8 Land use/Land Cover Objectives The terms land cover and land use refer to surface cover on the ground like vegetation, urban infrastructure, waterbody, vacant land, etc and purpose the land serves at that point like agriculture, forest, etc. Identification of land cover establishes the baseline information for activities like thematic mapping and change detection analysis. Land use refers to the purpose the land serves, for example, recreation, wildlife habitat, or agriculture.

Together the phrase Land Use / Land Cover refers to the categorization or classification of human activities and natural elements on the landscape in a specific time frame based on established scientific and statistical methods of analysis of appropriate source materials. The objective of assessing the existing land use/land cover of the area are:

• Establish the prevailing pattern of use of the land area & evaluate the scope for proposed project activities. • Indicate how the establishment of the proposed project will impact the physical & social environment of the area due to alteration of land use/land cover pattern. • Enables to envisage the scenario emerging due to the increase in demand for land with increase in population and the impacts arising due to the interface with various project activities. Land use Pattern in the Study Area It is observed that, major land use pattern of the PMLs is Agricultural land, followed by homestead land and plantation. The details of land use pattern in the study area is given in Table 3.1 and is graphically represented in Table 3.2. The land use pattern maps are shown in the Figures below.

3.9 Climate & Meteorology Climate and meteorology of a region are a significant parameter for assessment of environmental impact of a project during its implementation & operation phases. Meteorology plays a crucial role in understanding the predictive local air quality as there is an essential relationship between meteorology and atmospheric dispersion of gaseous pollutants involving the wind speed, wind direction and solar insolation. The meteorological data of IMD station at North Lakhimpur has been used for interpretation of longer-term temperature profile, relative humidity, wind speed and wind direction in the study area. In addition, monthly rainfall data obtained from Customized Rainfall Information System (CRIS), IMD has also been referred to understand the rainfall pattern of the area. The climate of Golaghat and Jorhat District is humid sub-tropical, dominated by the subtropical monsoon which is normally active from April to October with occasional winter showers. At times approach of monsoon is also marked by cyclones in April and May. The plains get flooded. Autumn and winter are dry seasons. The temperature varies from 3oC to 37oC and 04oC to 37oC (October to December) in Golaghat and Jorhat Districts respectively. The yearly rainfall for Golaghat district varied from minimum 1232 mm to maximum 1871 mm with an average rainfall of 1450 mm. The yearly rainfall for Jorhat district varied from minimum 1380 mm to maximum 2112 mm with an average rainfall of 1755 mm. Micrometeorological Parameters The Micrometeorological parameters were observed to assess the local climatic condition of the study area. Micrometeorological setup was installed at Kherema Gano (Borholla) which is located in the northern part of Titabor ML, sown in figure 3- 16. The micro met monitoring stations were installed at a height of about 10 m above the ground level, ensuring that there were no obstructions to the free flow of winds. The monitoring was conducted for 3 months from mid October 2019 to mid January 2020 and the prevailing meteorological conditions is tabulated below.

3.10 Ambient Air Quality The prevailing ambient air quality was assessed through a scientifically designed ambient air quality- monitoring network. The selection of the monitoring locations was based on the following: (i) meteorological conditions on synoptic basis, primarily wind direction;

(ii) accessibility and availability of infrastructure.

(iii) location of sensitive receptors in the study area

(iv) settlement area

(v) topography of the study area, and

(vi) representatives of likely impact areas,

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 70

The primary criteria of selection of monitoring locations were governed by predominant wind directions obtained from historic meteorological data of the nearest IMD station and physical accessibility of the locations. The ambient air quality monitoring was carried out at eight (8) locations in and around the study area, taking into considerations factors such as predominant up & down wind directions and cross wind direction of the proposed well locations, accessibility of the locations & presence of sensitive receptors in the Block area. The location of the 8 air monitoring locations is given in Table 3-3 below. The monitoring locations are shown in figure 3-17. Table 3-3.

3.11 Ambient Noise Quality The summarized results of noise levels are given in table 3-6. The noise levels are compared with Ambient Air Quality Standards in respect of Noise as per The Noise Pollution (Regulation and Control) Rules, 2000 stipulated for daytime and night time for residential land use. It is seen that the day time and the night time Noise levels (Leq) are within the prescribed limit. The graphical representation of noise level is present in figure 3.22.

Monitoring of noise levels around the study area has been carried out to assess the existing noise levels in the study area. Noise standards have been designed for different types of land use i.e. residential, commercial industrial areas and silence zones as per ‘The Noise Pollution (Regulation and Control) Rules, 2000, Notified by Ministry of Environment and Forests, New Delhi, February 14, 2000’. The ambient noise monitoring was carried out at eight (8) locations during baseline monitoring activity. The details of the noise monitoring locations is given in Table 3-5. Sound pressure level (SPL) measurements in dB (A) were recorded for every hour continuously for 24 hours at 15 minutes interval for the monitoring stations and equivalent noise levels in the form of Leq day and Leq night was computed. The day noise levels have been monitored during 6.00 am to 10.00 pm and night levels during 10.00 pm to 6.00 am at all the locations.

3.12 Ground Water Quality Primary monitoring of ground water quality was considered important in order to assess the baseline scenario of ground water in the study area and to understand the probable impacts of the proposed project activities on the sub surface aquifers. 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. Groundwater Sampling Locations For the purpose of baseline assessment, total 8 locations were identified for groundwater samples covering the study area and were examined for physico-chemical, heavy metals and bacteriological parameters to assess the current status of water quality in the study area during the monitoring period. The groundwater quality is likely would be variable within the Block due to spatial heterogeneity in the aquifer. These locations are spatially distributed across the PMLs and its surrounding areas. The sampling locations were selected to capture both shallow as well as deeper part of aquifer. All ground water samples were collected from bore wells/tube well. The sampling locations re tabulated below and presented in Figure 3-24. The results of GW monitoring is shown in Table 3-8. Photographs of sampling are presented in the next page.

Interpretation of Groundwater Quality Results Physical Parameters The colour of the samples was found <1 hazen units and with agreeable odour. The pH of water samples ranged from 7.3 to 7.6. Turbidity of all the samples found between 0.24 – 0.72, which is under the permissible limit of 1 NTU. The TDS in the water samples varied from 195 mg/l 335 mg/l, which is in compliance with desirable limit of 500 mg/l. Inorganic Parameters The total alkalinity of the samples varied from 114 - 216 mg/l which is within the acceptable limit except at GW3 - Mokrong Tea Garden where it slightly exceeds the acceptable limit. Total hardness of the samples varied from 104-186 mg/l and was within the desirable limit of 200 mg/l. The concentrations of heavy metals such as Iron, Nickel, Copper, Zinc, Arsenic, chromium, lead was below their corresponding permissible limit. Bacteriological Parameters Bacteriological parameters namely E. Coli, Faecal and total coliform were not detected in any of the groundwater samples collected for testing.

Polychlorinated biphenyls were below detection limit in all the location. The groundwater quality was found to be suitable for drinking purposes in almost all the locations as the major indicators like TDS, hardness, bacteriological parameters are within the acceptable limit of Drinking water specification IS 10500:2012, though primary and secondary treatment are preferable before consuming. 3.13 Surface water quality Primary monitoring of surface water quality was given importance during scoping of the EIA study as it is crucial to establish the baseline quality of the existing major watersheds and sub watersheds (comprising the major drainage of the study area) to identify any possible contamination due to any current industrial activities. Surface water quality monitoring location A monitoring network consisting of 7 locations for surface water monitoring was selected. Water sampling and analysis was done following CPCB standard guidelines for physical, chemical and bacteriological parameters. Surface Sampling Location is presented in Figure 3-24 presented earlier. Details of sampling locations and photographs of sampling is presented below.

Table 3-14 Soil Remediation Intervention Values as per Dutch Standards S. No. Parameter Intervention Values (mg/kg dry matter)

1 Zinc 720 2 Arsenic 76 3 Lead 530 4 Cadmium 13 5 Copper 190 6 Mercury (inorganic) 36 7 Nickel 100 Source: Soil Remediation Circular 2009, Minister of Housing, Spatial Planning and Environment, Netherlands. Note: Concentrations are shown for standard soil (10% organic matter and 25% clay)

As per the classification stated above, the following derivation was arrived at from the monitored data. pH pH of the soil samples ranged from 6.1 to 8.3. Hence, the soil could be classified from slightly acidic to neutral to moderately alkaline as per the Standard soil classification presented above

Texture and Electrical Conductivity Texture is an expression to indicate the coarseness or fineness of the soil as determined by the relative proportion of the various sized primary particles in the soil mass. The textures of the collected soil samples were found to be sandy loam type to loamy fine sand. The EC values for the soils monitored at the study area range between 99 and 279 µs/cm. For a productive soil, the electrical conductance (EC) should be < 100000µs/cm.

Macronutrients and Organic Carbon Nutrient status of the soil samples can be determined from the concentration of N, P, K and organic carbon in soil samples. Nitrogen contents in the soil samples ranged between 0.7 – 1.3%, phosphorus content in the soil samples ranged between 69.2 – 175.3 mg/kg and potassium contents ranges between 180.6 - 205.3 ppm. The nutrient content of the soil looks satisfactory.

Metals Heavy metals such as copper, lead, Nickel and zinc were detectable whereas the concentration of lead and mercury in the soil sample was below detection level in the soil of the study area. However the monitored values were below the soil remediation intervention values specified in Dutch Soil Remediation Circular. Sodium Absorption Ratio (SAR) - Sodium absorption ratio for the samples varied between 1.7 – 3.0.

3.15 Traffic Survey Traffic surveys were conducted within the study period in the study area, to analyse the traffic and transport network characteristics. Photographs showing traffic survey is presented below. The main objective of classified traffic volume count is to assess the traffic characteristics in terms of average daily traffic, hourly traffic variation, peak hour traffic, traffic composition and directional distribution. The traffic surveys were conducted continuously for 24 hours, manually on a normal working day and weekend. The survey was done for both way traffic movement and categorized the vehicles as heavy motor vehicles (truck, bus, dumper, tanker and trailer), light motor vehicle (car, jeep, van, matador, tractor, tempo and mini bus), two/three wheelers (scooter, motor cycle, auto, moped) and non-motorized vehicles (bicycle, tricycle). In order to express the intensity of traffic, it would be convenient to express mixed traffic comprising of different vehicle types in terms of passenger car unit (PCU). For this purpose, the PCU factors (IRC 106:1990) have been adopted as stated in Table 3-15

Description T1 T2 T3 T4 T5 T6 T7 PM PM PM AM PM 3.16 Ecological Environment An Ecology and Biodiversity study of Group B (Non-Forest), located in Golaghat and Jorhat districts of Assam, was conducted to recognise the possible impacts on biodiversity owing to drill development and exploratory well. The study was carried out in post-monsoon season during month of January 2020. A Total 8 transects, 30 quadrats and 6 aquatic sampling as well as primary productivity sampling locations were selected based on topography, land use, habitat and vegetation pattern. Faunal species were assessed by transect method by travelling a known distance (1 ± 0.05km) and observed faunal species along the length were noted. Primary data was collected through most of the diurnal period from early morning till late evening. Secondary data was collected from Divisional Forest Office of Jorhat and Golaghat and consultation with local people. Books like Trees and shrubs of India, the book of Indian Trees, Birds of the Indian Sub-continent, Indian Mammals- A field guide, Snakes of India, The Book of Indian reptiles and Amphibians and Freshwater Fish of Peninsular India were also consulted. Field identification has been based on professional experience, and following, standard field guides and identification keys were made use of. Fauna was checked for their IUCN status (International Union for Conservation of Nature, Red List Version 3.1) and their status in the Schedules of Wildlife Protection Act, 1972.

3.16.1 Methodology of the Study Floral Survey Methodology Primary data have been collected at ten sampling sites selected by applying the stratified systematic sampling method. Qualitative and quantitative data was collected at each sampling site, using the standard quadrat methodology. In each terrestrial ecology sampling locations three quadrat were laid i.e. 20m x 20m for trees, 5m x 5m for shrubs and 3m x 3m for herbs and a total of 30 quadrats. Table 3-15 presents details of the sampling sites, including location code, location coordinates, and habitat-profile of each site. The sampling locations are shown in the map presented in Figure 3-32 below.

Faunal species were assessed by transect method by travelling a known distance and observed faunal species along the length were noted. Analysis was done through direct observation or visual encounter techniques. Also, Evaluation of faunal species was also done by using indirect method such as scats, pug marks, prey kills, calls, nests, feathers, skin molts and road-kills. Apart from line transects, vantage point surveys were also conducted along the village ponds for aquatic birds. Eight line transects were laid in the study area. GPS locations of transects laid is given in following table 3.-21 and figure 3-33.

Important value index (IVI) is used to determine the overall importance of each species in the community structure. It is used to identify the dominance of any given species in the study area which helps in getting an overall importance of any given species in the community by statistical analysis. It can be calculated by summing the values of relative frequency, relative density and relative dominance. The IVI of the individual species has been calculated as the following formula

IVI=Relative frequency + Relative density + Relative dominance

The rationale behind the number of transect and quadrats laid was to ensure thorough and proportionate coverage of all the habitat types observed in the study area. Species diversity is the best measure of community structure and it is sensitive to various environmental stresses. General diversity of an area was calculated using the Shannon–Wiener diversity index. This was the index most used to calculate diversity of an area i.e. alpha-diversity. Besides diversity indices like Simpson's dominance index, Pielou's evenness index, and Margalef's richness index were also calculated by using PAST version 3.07. Shannon–Wiener diversity index and Simpson's dominance index both were based on the proportional species abundance in the studied area. However, Shannon–Wiener diversity index was more sensitive to rare species, whereas Simpson's dominance index gave more importance to common species. Pielou's evenness index reflects homogeneity among the species. Margalef's richness index considered both abundance and species richness.

Desktop review and Secondary Data Collection

A desktop review has been carried to identify the forest area, land use pattern, Vegetation type etc. information regarding sensitive ecological habitat such as Biosphere Reserve, National Park, Wild life Sanctuary , Game reserve, Conservation reserve also collected from sources such as Forest Working Plan of Jorhat and Golaghat, different Scientific report published in peer reviewed journals, Government reports. To identify the different classification of different forest types, report from Forest Survey of India (SoFR, 2017) was consulted Stakeholder consultation with forest Department and local villagers was also carried out to gather the relevant information during field survey.

3.16.3 Terrestrial Ecology Flora of the Study Area The floristic baseline was carried out after considering the different habitats present in the study area. Forest types are also identified as per the Champion and Seth Classification, 1967. Forest working Plans of Golaghat and Jorhat District are also consulted during identification of Forest types. Forest Types The Study area are located within the Jorhat and Golaghat district of Assam. Both of the district receives heavy rain fall in the monosson season and moderate to light rainfall rest the year which. This type of rainfall helps to development of forest area. In Golaghat District, 18.91 % of the Geographic area comes under forest cover whereas in Jorhat Dostrict, 19.65 % of geographic area falls in the forest area (SoFR. 2019). The Major forest types which are observed in the study area are Tropical Wet Evergreen forest, Alluvial Semi-Evergreen forest and Moist Mixed Deciduous Forest.

Floristic Species Recorded

A consolidated list of flora species observed in the study area, prepared on the basis of primary survey has been provided in following Table 3-22. and 3-23. Orchids such as Cymbidium aloipholium, Dendrobium aphyllum, Rhynchostylis rhetusa, Aerides rosea, Bulbophyllum sp, Papilionanth teres, Dendrobium densiflirum and Papilionanthe teres were observed in the study area.

Trees

The study area comprises of 44 tree species belonging to 25 families. Diversity of species belonging to Fabaceae family was found to be higher, followed by Arecaceae, Moraceae, Myrtaceae, Meliaceae and Lamiaceae. Most common species were Areca catechu, Mangifera indica, Euclyptus sp., Polyalthia longifolia and Artocarpus intergifolia.

Among trees Mangifera indica (21.18), Artocarpus intergifolia (15.28), Euclyptus sp. (13.77), Areca catachu (13.58) are the dominant species observed in the study area.The floral diversity was found to be medium to high as Shannon’s index value varied from 2.25-2.73. Whereas Simpson’s indices value varied very less (0.89-0.93), that means no single specie was dominant in that project sites. Margalef's richness index varied from 3.51-5.09, that means species richness varied with the change of habitat. Whereas Pielou's evenness index was varied very less (0.91-0.98), that means in project sites all species were evenly distributed. Quadrat wise value of all diversity indices are given in following Table 3-22.

3.16.6 Aquatic Survey Methodology For phytoplankton analysis one litre of water sample has been collected from each collecting point, and 10% Lugols’ Iodine solution mixed instantly on the spot in 100:1 ratio. All collections have been done before 10 am in the morning. Sampling bottles have been kept for about 6hrs and then, the 10-mL precipitation has been collected from the amber bottle. The identification and quantitative analysis of phytoplankton samples have been done by using Leica microscope.

For qualitative and quantitative analysis of zooplankton, the samples have been collected by filtering 50L of water using No. 25 bolting silk cloth plankton-net (with 64µm aperture size and allowing nearly 33% open area). Sample volumes of 100 ml has been maintained for all sample bottles. Zooplankton have been estimated by Lackey – Drop Method (1938). From decanted sample subsamples of 0.2 ml each has been taken in a microscopic grooved slide and then covered by square cover glass of known area. Ten such counts have been averaged and the organisms present in a litre of water.

Phytoplankton The species distribution of the phytoplankton as found after sampling at six sites are summarized in Table 3-36 while Site wise diversity indices are given in 3-37. Six Phytoplankton class were identified from the six sampling points. The highest phytoplankton was observed under Bacillariophyceae class followed by Chlorophyceae and Cyaenophyceae. Due to river flow the number of phytoplankton were encountered very low. Also, Shannon diversity index, Simpson dominance and Margalef index was very low in all sites.

Zooplankton

The species distribution of the zooplankton as found after sampling at six sites are summarized in Table 3-31 while the Site wise different diversity indices are given in Table 3-32. 16 genera of zooplankton under four zooplankton groups were identified from the six sampling points. Rotifers were the dominated species followed by Cladocera. Like phytoplankton, due to river flow the number of zooplankton present in six sampling area were very low. Same as phytoplankton the Shannon diversity index, Simpson dominance and Margalef index was also very low.

3.16.7 Primary Productivity

Primary productivity is a term used to describe the rate at which plants and other photosynthetic organisms produce organic compounds in an ecosystem. There are two aspects of primary productivity:

Gross productivity is the entire photosynthetic production of organic compounds in an ecosystem.

Net productivity is the organic materials that remain after photosynthetic organisms in the ecosystem have used some of these compounds for their cellular energy needs (cellular respiration).

Primary productivity will be calculated using Winkler’s light and dark bottle method. The technique developed by Gaarder and Gran uses variations in the concentration of oxygen under different experimental conditions to infer gross primary production. At all six sites initial dissolve oxygen (DO) was measured and one pair of water filled light and dark bottles were immersed in water for one hours. After that dissolve oxygen (DO) of the dark bottles and light bottles are measured. The photosynthetic quotient (PQ), which is the ratio of moles of oxygen released to moles of C fixed, was taken as 1.2. The primary productivity of river water was very low due to low phytoplankton assemblages as shown in Table 3-40.

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 etc. The assessment attempts to predict and evaluate future impacts of project upon people, their physical and psychological health and well-being, their economic facilities, cultural heritage, lifestyle and other value system and helped in prioritizing ONGC Jorhat Asset’s commitment towards the CER initiatives. Inputs from the social assessment into the design phase facilitated in:

• Tracking potential adverse effects over different time frames and different 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 for the population in the vicinity of the project site.

nature of project operation and understanding the demographic characteristic of the area.

Secondary Data Analysis To evaluate socio-economic environment in the study area, secondary information from the 2011 Census handbook has been referred to and details pertaining to habitations in the study area have been extracted and assessed. Apart from that district level secondary information has also been collected for district statistical hand book, Year 2011.

Stakeholder Consultation

At the beginning of the EIA process, the AECOM team conducted a preliminary identification of probable stakeholders. An inventory of potential stakeholders, including local groups and individuals, local institutions like panchayats which may be directly or indirectly affected by the project or with interest in the development activities of the region was made at preliminary. Consultations with community are a continuous process that was carried in the EIA process and would be continued during the construction and operation phases of the project. Issues like land and resource damage, social disturbance, severance and increased congestion, noise and air pollution, employment opportunities, need for development of basic infrastructure, safe drinking water, sanitation facilities in the villages located in the periphery of the seven (7) PML block areas, have been discussed during the consultations so that they can be adequately addressed through the environment management plans. The consultations also helped in developing preliminary understanding of the requirement of social development initiatives, which are required in the project village and may be undertaken as part of the CER activity.

3.17.3 Socio-Economic profile

Demographic Profile Demographic details are details related to statistical and dynamic aspects of a population. Data related to households, population, sex ratio, caste, literacy rate was obtained from Census, 2011 that is conducted every 10 year since 1872.

Population and Household

Population and households are basis units of demography. A population in statistics can be defined as a discrete group of people that are identical with at least one common characteristic whereas a household is majorly composed of two or more persons who are occupying a single housing unit. Details of the population and households was obtained from District Census, 2011 handbook of Jorhat district

Total number of 108 villages in Golaghat District and 26 villages in Jorhat District are situated in the within and in the close proximity of the seven (7) PML Blocks. According to Census 2011, the household size within 134 villages ranges from 3.97 to 5.96. The average household size is 4.66 which is comparable to the Assam state average of 4.7. Gomariguri (5378) in the Golaghat district and Borholla T.E. (3738) in the Jorhat district show the highest population among the villages in the seven (7)

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 141

PML areas. The lowest population is observed in Bil Gaon (8) and Kechabebejia (275) in the Golaghat and Jorhat districts respectively.

Sex Ratio

The average sex ratio in identified 134 villages is observed to be 970 females per 1000 males (Census 2011). The extremity in the sex ratio is observed in Golaghat district with the lease observed sex ratio is in Phulbari and highest in Mokrong Pathar with 829 and 1361 females per 1000 males. The state of Assam shows a sex ratio of 958 females per 1000 males, according to which the least sex ratio is comparable to the state ratio and the observed highest exceeds the state ratio.

SC/ ST Communities

According to the Census., 2011, SC population, on an average account for 2.55%, with the maximum percentage being observed for Rupkolia (84.08%) in Golaghat district. ST population on an average is 10.81 % and the Bijoupur Baghdhora (97.66 %) shows the highest observed ST population. It was further observed that most of the villages does not have population belonging to the SC / ST Community.

Literacy Rate

Literacy, as defined in Census data, is the ability to read and write with understanding in any language and literacy rate is a key indicator of the level of education prevalent amongst the sample population. It is also considered as one of the key factors of socioeconomic progress. All children of age below 7 years are treated as illiterate. People who are blind and could read in Braille are also treated as literates. The state of Assam has an average literacy rate of 73.18 %. The villages in the close proximity and within the seven (7) PML areas shows an average literacy rate of 79.33 % which is slightly higher than the state average. The least and highest literacy rate is observed at Khutakota (30.31 %) and Sarukachari (99.51 %) respectively, both being located in Golaghat district. The average male literacy rate is 84.93 %, which is higher than the female literacy rate in the identified villages. The observed female literacy rate as per Census, 2011 is 73.61 %.

Occupation and Livelihood

Economic condition of any village can be defined on basis of its work force participation. Work force participation rate is defined as the percentage of total workers (main and marginal) as compared to the total population. Main workers are considered as those workers who have been engaged in any economically productive activity for 183 days or more while marginal workers are those that have worked for less than 183 days in a year. Marginal Workers can be further classified in four broad categories, i.e., cultivators, agricultural labourers, household industry workers and other workers. Work Participation Ratio (WPR) is defined as percentage of total workers including main and marginal workers out of the total population of the study area. The average WPR is the identified village is 50.82 % with main working population being 63.68 %. The marginal working population is 36.32 % with majority of the population being involved in cultivation (18.96%) and 2.64 % being involved in agriculture. Among the various marginal working population, 21.89% of the

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 142

population is involved in household activities and a major 49.18% belongs to other form of marginal workers.

Social Infrastructure Health Facility Health is an important aspect concerned with wellbeing of an individual physically and mentally. Health of the people affects socio-economic condition of a community and is also linked with the environment. The healthcare facility is divided into a three- tier system in rural area, which is given as follows:

1. Sub-centre: The Sub Centre is the most peripheral and first contact point between the primary health care system and the community. The major task sub-centres are assigned are to provide service associated with maternal and child health, nutrition, family welfare, immunization, diarrhoea control and control of various communicable diseases programmes. The primary health sub-centres present within the identifies villages is 12. The number of doctors as per the Census, 2011 is observed to be 33.

2. Primary Health Centre (PHC): PHC is the first point of contact between village community and the medical officers. The Centre was envisaged to provide facilities integrated with curative and preventive health care to the rural population, majorly focusing on various preventive and promotive aspects of health. According to Census, 2011, there are 8 PHCs within the identified villages. The total strength of doctors is 27.

3. Community Health Centres (CHCs): CHCs are maintained by the State government under MNP/ BMS programme. As per norms, a CHC is required to be managed by 4 medical specialists (surgeon, physician, gynaecologist and paediatrician) including 21 paramedical and other required staff. It has 30 in-door beds with one OT, X-ray, labour room and laboratory facilities. It has been observed that no CHCs are located within the identified area.

Education Facility

37% of the villages have access to Govt. pre-primary school (Nursery/ LKG / UKG) while 88.8% villages have a Govt. Primary school. Govt. middle schools and Govt. secondary schools were present in 43.28% and 23.88% of the villages in the study area, as per the Census of India, 2011. Govt. senior secondary schools were present in 5.22% villages. It has been observed that there is no presence of Govt. Colleges in the study area.

Drinking Water

41.7% and 43.28% of the total villages in the study area has access to covered well and uncovered wells respectively. 91% of the villages have access to hand pumps and 74% of the villages in the study area has access to tube well or bore wells.

Sanitation

3.73% of the villages are covered under the Total Sanitation Campaign (TSC). The community toilet complex including a bath is not present in any of the villages located within the study area and Nalani Pothar is the only village having access to the community toilet complex with a bath. The study area is devoid of community waste

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 143

disposal system (house to house collection) and community bio-gas or recycle services.

Electricity

87% of the villages in the study area has access to power supply for domestic use.

Post Offices The study area encompasses 134 villages, out of which 6 villages have post-office services.

Community Consultation

Consultation with the local people was carried out with the objective of finding out about people's views and opinion on issues relating to the project, its operations and also to the peripheral development. In this backdrop, extensive public consultations were conducted during the socio-economic assessment as part of EIA study. Suggestions were also received from participants on managing of project functions so that it does not have any adverse impacts on the community living in the area adjoining the project, better targeting community development programs, ensuring community involvement and cooperation in the operation of the project. The feedback from the continued consultation will facilitate the project in developing strategies to address these issues in consensus with the communities residing around the project. Community consultations in this project are mainly carried out the village located within the study area comprising of the villages within the PML area and within its near proximity of the PML boundary.

Key points of Stakeholder Consultation

Consultation with several group of stake holders, reveal the socio-economic issues, of the targeted villages:

• Most of the villagers facing a problem of drinking water facility. • There is no adequate health care facility nearby. • Road condition is not well maintained. • Most of the villagers has a facility of pucca toilet, but some population are habituated in open defecation. • Some villagers are benefited y ONGC’s CSR programme, during the previous drilling activity.

4. Anticipated Environmental Impact and Mitigation Measures

This chapter presents the identified environmental impacts due to the proposed project and outlines alternatives any mitigation measures for minimizing adverse impacts. 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 affected. The matrix considers physical, biological and socio-economic components of the environment on one axis (X axis) and various project activities on the other side (Y axis). Aspects and impacts on environmental components which would be relevant to the different phases of the project e.g. pre- drilling activities, drilling, early production decommissioning have been addressed in the matrix. Environmental and socio-economic components were identified based on applicable legislations, project specific features, site reconnaissance visits baseline environment monitoring & field survey and discussions with stakeholders.

Potential environmental impacts that may result from any of the identified project activity has been identified in a matrix based on activity-component interaction and is presented in table below. The impacts which has been identified in the matrix have been assessed for its significance based on significance criteria delineated below.

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:

• 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 life-cycle 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:

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 146

Table 4-1 Impact Prediction Criteria Impact Criteria Ranking Elements Severity − Regional impact resulting in long term and/ or medium 3 damage to the natural environment. − Major impact on community and occupational health (e.g. serious injury, loss of life) on account of accidental events viz. well blow-outs and related operational activities. − Permanent Loss of land/livelihood − Local scale impact resulting in short term change and / 2 or damage to the natural environment. − Temporary loss of land, source of livelihood for affected communities − Local scale impact on terrestrial habitat, endangered species, drainage pattern and community resources. − Moderate impact on occupation and community health & well being (e.g. noise, light, odour, dust, injuries to individuals) − Complaints from the public, authorities and possible local media attention. − Limited local scale impact causing temporary loss of 1 some species etc. − Limited impact on human health and well-being (e.g. occasional dust, odour, light, and traffic noise). − Public Perception/Concern Extent − Regional scale impact and including impacts to 3 physical, biological and socio-economic environment of the block − Largely local level impact limited to immediate vicinity of 2 the proposed well sites − Impact not discernible on a local scale and is limited 1 within the boundaries of the drill site Duration − The impact is always likely to occur during the entire 3 project life cycle . − The impact is likely to occur in some phases of project 2 life under normal operating conditions. − The impact is very unlikely to occur at all during project 1 life cycle but may occur in exceptional circumstances.

A positive or beneficial impact that may result from this project has not been ranked and has been depicted in the form of ++.

Impact Significance

The significance of impact has been determined based on a multiplicative factor of three element rankings. Table 4-2 depicts impact significance in a scale of LOW- MEDIUM-HIGH and will be used for suggesting preventive actions, if any, and management plans for mitigation of impacts.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 147

Impact significance has been determined considering measures which have been taken into account in the design & planning phase of the project. Legal issues have been considered, 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.

Table 4-2 Criteria Based Significance of Impacts

Duration of Impact Significance Severity of Impact Extent of Impact (A X B X C) (A) Impact (B) (C) 1 1 1 1 1 1 2 2 Low 1 2 1 2 1 1 2 2 2 1 2 4 1 2 2 4 3 1 2 6 Medium 1 3 2 6 2 2 2 8 3 2 2 12 2 3 2 12 2 2 3 12 3 3 2 18 High 3 2 3 18 2 3 3 18 3 3 3 27 - Beneficial Impact - ++ Positive

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 addition to ranked weights, significance of impacts has been depicted using colour codes for easy understanding. In case an environmental component is impacted by more than one project activity or the activity would impact a sensitive receptor e.g. settlement, school, hospitals, forest etc. a high significance ranking of “>12” has been considered. A second evaluation matrix presents significance of impacts after considering that proposed mitigation measures will be implemented.

The impacts on each of the environmental components and its significance during the different stages of the project have been discussed in detail in the following section. 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 and socio-economic components during various phases of the project lifecycle. 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, testing and early production activities also include positive socio-economic impacts in terms of increase in local business opportunities & employment generation and on a larger perspective, by providing potential energy security at a national level.

4.3 Potential Impact and Mitigation Measures on Visual Environment & Aesthetics The seven concerned PML is an operating oil field, which has a number of development and exploratory wells, as well as existing well locations are also present. In this Block, awareness about drilling activity for exploration/development of oil persists amongst local people. Visual impacts on local people are envisaged during the construction as well as operation phases of the project.

Assessment of Impact

• During site preparation activity, dust will be generated due to the transportation of construction material, machinery and personnel, irregular dumping of construction waste and traffic movement in the site. Visual and aesthetic impacts are likely to be experienced by communities residing in or passing through villages located in the vicinity of exploratory well. However, considering the temporary nature of site preparatory activities and implementation of necessary mitigation measures by the proponent with respect to the siting of well locations (borrow areas, use of existing infrastructure etc.), the impact will be of low significance. The development well pads are present for long term and hence the duration of visual impact will be for a long term.

• Visual impact due to the operation of drilling rig and presence of base camp will not be considered significant given the temporary nature of short or long term exploratory/development activities (about 45-60 days to few years) and provided the well is indicative of any commercial hydrocarbon reserve. The DG sets will be housed in acoustic enclosure, but the size of the DG set in the enclosure along with its stack that is continuously emitting is not aesthetically or visually pleasing.

• The construction of drill pad, drilling of wells, construction of pipeline and decommissioning will involve a continuous day and night process, hence the high power, lighting (halogen) at night may be a source of visual discomfort to the residents of nearby settlements. Other than that light generated from flaring events might also be visually discomforting at night. However, flaring is

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 157

likely to be of intermittent in nature and at ground level, to occur only during process upset and production testing.

Impact assessment:

Severity of Impact 1 Extent of Impact 2 Duration of Impact 2 Impact Significance = 4 (Low)

Mitigation Measure o All the construction activity would be restricted within the designated site and there ae no scattering of construction materials and discarded wastes. o Fugitive emission from construction site will be suppressed through periodical water spraying at disturbance area; o After construction activities are completed, all temporary structures, surplus materials and wastes will be completely removed; o Construction wastes and municipal solid waste would be temporarily stored separately at the sites and transported to the designated disposal site/facility at regular intervals; o Adequate measure would be taken to orient the halogens at the construction facility. Excess lighting should not be used. o After decommissioning of rig and associated facilities, drill sites will be restored to its previous state, at possible extent – drill platform will be removed, pits & garland drains will be filled up, construction material will be buried in the pit; o Site will be rehabilitated by laying of top soil. It is considered that the above mitigation measures would further help to reduce the identified impacts. 4.4 Potential Impact and Mitigation Measures on Land Use

Assessment of Impact

ONGC would have to take the land for short/long term lease from local panchayat/land owners. In short /long term lease, land will be converted from agricultural land to industrial land. After the completion of the lease period the land will be reinstated. Additionally, necessary measures will be adopted by ONGC through provision of adequate compensation against loss of standing crops. Once the drilling activities are completed, the rig would be dismantled and the drilled oil will be conveyed through underground pipeline. package. There may be impact on the surrounding land use due to disturbance in the micro drainage pattern of the project area due to construction and drilling activities.

Severity of Impact 2 Extent of Impact 2 Duration of Impact 2 Impact Significance = 8 (medium)

Mitigation Measure.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 158

• Levelling and grading operations will be undertaken with minimal disturbance to the existing contour, thereby maintaining the general slope of site; • The excavated material from the drill site should be stored (temporarily /permanently) in uncultivated/vacant land and away from any drainage channel. • Provide adequate compensation to landowners against loss of standing crops in accordance to regulatory requirements viz. Petroleum & Mineral Pipelines (PMP) Act, Land Acquisition Act, 1894 (amended in 1984) and Scheduled Tribes and Other Traditional Forest Dwellers Right, 2006. With adoption of these mitigation measures, the impact on land use due to the proposed project would further reduce its significance. 4.5 Potential impact and Mitigation Measures on Topography & Drainage

Impacts during road & site development

Potential impact on drainage is primarily anticipated in the form of disruption of natural drainage pattern during site preparation and approach road construction. Site preparation may involve rising of the land from the ground level which may lead to alteration of onsite micro-drainage pattern leading to potential problems of obstruction of natural flow of water. This problem is likely to be further aggravated due to heavy rainfall experienced in the districts of Jorhat & Golaghat. The access to majority of the drill sites is characterized by paved and unpaved rural roads. Since the PML are already operational, existing access roads are already available. However, site approach road needs to be constructed. Widening and strengthening of existing paved/unpaved road will be required for transportation of drilling rig and heavy equipment to the well site. Widening/ new construction of roads could result in the alteration of drainage unless proper cross drainage structures are provided and may lead to water-logging of adjacent lands. The strengthening of the access road would require some earth works especially at the sharp bends. The existing access road, culverts will not be disturbed. Thus, no change in the micro- drainage pattern along the access roads is expected. Considering the above, the impact is considered of medium significance.

Pipeline Construction

The construction of pipeline for transporting the hydrocarbon to the nearest GGS would lead to soil excavation along the route of pipeline. The construction of pipeline would be as per the topography of the area. This may cause adverse impact on the micro drainage of the area.

Well Site Restoration Site restoration will be initiated for well site not indicative of further commercially exploitable hydrocarbon reserves. Unplanned restoration may lead to the long-term disruption in natural drainage pattern and water logging in neighbouring agricultural land adjoining the site. However, adequate care will be taken by ONGC to restore the site back to its original condition based on the originally existing contours and predominant slope to prevent any such adverse drainage impacts. The impact is

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 159

considered to be of low significance with onsite drainage being dependent on the proper site restoration.

Severity of Impact 1 Extent of Impact 2 Duration of Impact 2 Impact Significance = 4 (Low)

Mitigation Measure

• Levelling and grading operations will be undertaken with minimal disturbance to the existing contour, thereby maintaining the general slope of site; • Provision of drainage system will be made for surface run-off • Disruption/alteration of micro-watershed drainage pattern will be minimized to the extent possible. • Loss of micro-watershed drainage, if any, is to be compensated through provision of alternate drainage

With adoption of these mitigation measures, the impact on topography and drainage would be insignificant. 4.6 Potential Impact and Mitigation Measures on Air Quality

The probable sources of impact on ambient air quality during different phase of the project are listed below.

• Pre-drilling phase, construction of production facilities: o Site development; o Operation of vehicles and construction machinery; o Transportation, storage, handling of construction material, disposal of construction waste; o Operation of DG sets • Drilling phase: o Operation of DG sets; o Emissions from flare stack; o Transport of drilling chemical and manpower etc. o Early production phase and liquid mud plant • Operation of Production facilities o Emission from DG sets o Emission from flare stacks • Construction of Pipeline o Emission of particulates • De-commissioning phase: o Decommissioning of rig and associated facilities; o Transport of de-mobilised rigs and machineries Control measures adopted as a part of Project design are as follows: • Vehicle, equipment and machinery used for drilling would conform to applicable emission norms; • Drilling chemical and materials would be stored in covered areas to prevent fugitive emissions;

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 160

• DG set stacks would have adequate height, as per statutory requirements, would be able to adequately disperse exhaust gases; • Water sprinkling at strategic location at periodic interval, especially during dry season

Assessment of Impact: The potential impact due to above mentioned activities has been discussed in the following section. Fugitive emission from handling of construction material, vehicular transport, pipeline construction, material handling during drilling & decommissioning phase: Fugitive dust emissions due to the proposed project would be principally associated with emissions of dust during the site preparation. The dust generated would be primarily from the handling and transportation of fill material and re- entrainment of dust during movement of the vehicles on unpaved roads. The generation of such fugitive dust is likely would be governed by micro-meteorological conditions (wind speed and direction).

Emissions from Vehicles/Equipment: The pre-drilling, drilling and decommissioning operations would involve movement of diesel operated vehicles and operation of machineries and equipment. Movement of heavy vehicles would be particularly intense during site preparation and decommissioning phases. Gaseous pollutants such as NO2, SO2, are likely would be emitted from operation of vehicles and machineries.

Impacts from Operation of DG sets and Flaring: The proposed project would involve the operation of 3 DG sets, each of capacity 750 KVA. Combustion of fuel in a DG sets typically happens at high temperatures resulting in generation of considerable amounts of NO2. The SO2 concentration in emissions is dependent on the Sulphur content in fuel burnt and particulate matter emitted consists of unburnt carbon particles. The emissions from the DG set would be discharged into the atmosphere through a stack of adequate height. Flaring of gases primarily during the drilling testing phase will contribute to additional air pollution. Flaring involves high temperature oxidation process to burn combustible gases that may be generated from the proposed well sites. The pollutant of concern from flaring would be NOx and SO2. However, ground flaring is generally conducted as per existing practice and it is envisaged that this would be continued.

Severity of Impact 1 Extent of Impact 2 Duration of Impact 2 Impact Significance = 4 (Low)

Potential Impact and Mitigation Measures on Air Quality Prediction of impacts on air environment has been carried out employing mathematical model based on a steady state Gaussian plume dispersion model designed for multiple point sources for short term. In the present case, AERMOD dispersion model based on steady state gaussian plume dispersion, designed for multiple point sources for short term and developed by United States Environmental Protection Agency [USEPA] has been used for simulations from point sources.

Model Input Data

Emission from DG set

The power requirements for the development is met by using diesel generator sets. Six(4W+2 Standby) generators of each 750 kVA are installed at the site. The DG sets are primary contributor to air pollution at the development site. The pollutants emitted by a DG set consists of Particulate Matter (PM), Sulphur-di-oxide (SO2) and Nitrogen Oxides (NOx). Combustion of fuel in a DG set typically happens at high temperatures resulting in generation of considerable amounts of NOx. The SO2 concentration in emissions is dependent on the Sulphur content in fuel burnt and particulate matter consists of unburnt Carbon particles. As the fuel used is low sulphur HSD, lesser amount of SOx emissions are envisaged. For the particular drilling site during development, there will be 3 operating DG sets, as detailed below.

Comments on Predicted Concentrations A perusal of Table 4.5 reveals that the maximum incremental 24 hourly ground level concentrations for PM, SO2, NOx likely to be encountered due to DG sets are 0.56 μg/m3, 0.75 μg/m3, 16.0 μg/m3 occurring at a distance of 0.5 km in WNW direction. The predictions indicate that the PM, SO2 and NOx concentrations are likely to be well within the prescribed limit for residential and rural zone.

Mitigation Measures: Measures proposed to mitigate the effects of air emissions are as follows: • Location of construction materials will be away from nearby worker’s camps; • Proper handling of materials to ensure minimal emission of dust.

To minimise emission from the vehicles, equipment and machinery the following measures would be adopted:

• Movement of construction vehicles will be minimised, and minimum speed will be enforced along the access and approach roads; • All diesel-powered equipment will be regularly maintained, and idling time reduced to minimise emissions; • Low sulphur diesel will be used in diesel powered equipment and best management practices would be adhered to; • Vehicle / equipment air emissions will be controlled by good practice procedures.

4.7 Potential Impact and Mitigation Measures on Noise Quality Potential impact on ambient noise level is anticipated from vehicular movement, operation of construction machinery, access road construction & strengthening during well site preparation and operation of drilling rig and ancillary equipment during drilling operation.

The potential impacts on noise quality may arise out of the following: A- Pre-drilling phase: a. Operation of machineries & equipment; b. Site development/preparation c. Vehicular traffic; d. Operation of DG sets. B- Drilling phase: a. Operation of DG sets and drilling rig b. Operation of machineries & equipment; c. Vehicular traffic. C- Decommissioning phase: a. Demobilization activity b. Vehicular traffic.

Studies indicated that noise generated from operation of drilling rig generally varies in the range of 88-103 dB(A). Other contributors of high noise level at the exploratory well site include shale shakers, mud pumps and diesel generators. The average equivalent noise levels of drilling rig and ancillary equipment is estimated to 96 dBA. 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 500m) of the rig facility. Occupational health and safety impacts viz. Noise Induced Hearing Loss (NIHL) is also anticipated on personnel working close to such noise generating equipment. However, as a part of standard operating practice, necessary noise prevention and control measures viz. use of acoustic barriers, provisions for proper PPEs, regular preventive maintenance of equipment etc. would be implemented. Adequate engineering control on equipment and machinery (like mufflers & noise enclosures

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 167

for DG sets and mud pumps) would be installed to reduce noise levels at source, carrying out proper maintenance and subjecting them to rigid noise control procedures. The drilling period would last up to a period of 45-60 days. The significance of impact would be as follows:

Severity of Impact 2 Extent of Impact 2 Duration of Impact 2 Impact Significance = 8 (medium)

Mitigation Measures: Typical mitigation measures for noise will include the following: • Providing a green buffer at the fence line of the well pad site facing the sensitive receptors to further attenuate the noise propagation beyond the well pad boundary • 100 meters buffer area from the boundary of the well pad would be maintained to prevent uncalled disturbances due to noise generations on the sensitive area such as school buildings, primary health center, etc particularly during operation phase. • Periodical monitoring of noise level within 500 mts buffer area around well pad. • Undertaking preventive maintenance of vehicles and machine to reduce noise levels 4.8 Potential Impact and Mitigation Measures on Surface Water Quality Impact Assessment

Surface run-off discharge Site clearance and stripping of top soil during construction/preparation phase 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. However, there will be provision of onsite drainage system, sediment control measures, provision of oil water separator to aid discharging of surface run off in compliance with the CPCB Inland Water Discharge Standards. Discharge of drilling mud and process wash water Approximately 15-20 m3/day of drilling waste water is likely to be generated per well site during drilling operation. The drilling wash water so generated may be characterized by presence of oil and greases, barites and heavy metal which on discharge to nearby natural drainage channels or rivers may lead to possible surface water contamination. However, ONGC has considered to use water based mud, for the proposed project, temporarily storage of drilling waste in HDPE lined pit and subsequent treatment to ensure conformance with CPCB MINAS standards for Onshore oil and gas drilling and extraction and guidelines provided by MoEF&CC under the Hazardous wastes (Management, Handling and Transboundary movement) Rules, 2008. Severity of Impact 2 Extent of Impact 1 Duration of Impact 2 Impact Significance = 4 (low)

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 168

Mitigation Measures

• Proper treatment of all wastewater and produced water discharges will be made to ensure that they comply with criteria set by the regulatory body (MoEF&CC and SPCB). • Waste mud to be stored in the HDPE lined 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. • An oil-water separator will be provided at the storm water drainage outlet, to prevent discharge of contaminated run-off. • All chemical and fuel storage areas, process areas will have dykes/bunds around it to prevent escape of contaminated surface run-off into the storm-water drainage system.

4.9 Potential Impact and Mitigation Measures on Ground Water Resource Groundwater extraction has not been envisaged for the proposed exploration & development project. However, there would be impact on the groundwater resource due to the drilling activity. The drilling will be to a depth of 2200 – 3300 m. As per the report of CGWB of Jorhat district, there are about five to six aquifer systems with limited thickness exist within the depth range of 400 m. In the southern region, the aquifer system fades out due to mixing of finer particles of sand and clay and the thickness of the aquifer system decreases. Though, through the data logging service, the information about the drilling depth, where the drill will cut through the aquifer zone, would be acquired. Sometimes, during this activity an unquantified quantity of water does flow out as the rig cuts across the aquifer zone before cementing and casing is done. However, cementing and casing would be done within few hours to prevent the same. Possibility of contamination of subsurface and unconfined aquifers may happen 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 drilling waste and mud in an open/unpaved pit. However, the toxicity test of the drill cuttings of nearby wells of Assam Arakan-Assam Basin has shown the absence of any hazardous chemicals.

Severity of Impact 1 Extent of Impact 2 Duration of Impact 2 Impact Significance = 4 (Low)

Mitigation Measure • Wastewater would be temporarily stored in impervious pits. 4.10 Potential Impact and Mitigation Measures on Soil Quality Potential impact on soil quality is envisaged in the form of increase in soil erosion and loss of soil fertility resulting from site clearance and top soil stripping during well

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 169

site preparation. The impact from accidental spillage resulting from storage and handling of mud chemicals is also envisaged.

Source of Impact: Soil quality impacts can result from: D- Pre-drilling Phase: a. Removal of top soil from the land procured; b. Compaction of soil; c. Disposal of construction waste/ MSW in non-designated area; d. Spillage of chemical/oil on open soil; e. Surface runoff from material & waste storage areas and oil spillage area. E- Drilling Phase/Operation of Production facilities: a. Spillage of chemical, spent mud, hazardous waste, etc.; b. Surface runoff from waste storage area and spillage area. F- Decommissioning Phase: a. Disposal of decommissioning waste materials in open soil.

Site clearance and stripping of top soil

Most of the land in the seven PMLs are used for agricultural purpose. Stripping of top soil likely to affect the soil fertility of the well sites. During decommissioning, proper restoration of site will be undertaken by the proponent. Necessary surface run-off control measures will be adopted by the proponent during construction phase to prevent contamination of adjoining lands from discharge of surface run-off characterized by increased sediment load. The top soil will be stored in mound form and preserved in a manner so that its fertility is maintained.

Storage and disposal of drill cuttings

It is estimated that nearly about 225 m3 of drill cuttings is likely to be generated from each well during exploratory and development drilling operation. Improper storage and disposal of process waste on open soil or unlined areas may lead to the contamination of soil onsite and abutting land if not properly managed. As an embedded mitigation measures HDPE lined impervious pits would be constructed at each of the drill sites for temporary storage of drill cuttings and drilling fluid. The disposal of the drill cuttings and the drilling mud would be carried out in accordance with “CPCB Oil & Extraction Industry Standard – Guidelines for Disposal of Solid Wastes. As WBM will be used, drill cuttings and waste drilling mud generated are likely to be non-hazardous in nature and is not anticipated to pose any potential threat to the soil environment. The waste cuttings will be tested and accordingly disposed by ONGC.

Storage and handling of fuel and chemicals

Fuels, lubricants and chemicals used for the drilling operations (especially daily consumption) would be stored at site. In addition, spent lube, and waste oil would also be stored temporarily at site before it is disposed as per the regulatory requirements. Improper storage and handling of the chemicals and fuels spent lubricants can lead to contamination of soil. Accidentally, spillage of chemicals, oil and lubricants, either during transportation or handling, on soil may contribute to soil contamination. It is proposed to have Appropriate Spill prevention kit handy.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 170

Severity of Impact 2 Extent of Impact 2 Duration of Impact 2 Impact Significance = 8 (medium)

Mitigation Measures: The following mitigation measures are proposed for reducing impact on soil quality:

• The top soil will be stored properly; in mound form upto a height of 2m and a slope angle of 30˚ • A jute mat will be over layered 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. • Adopt best practices e.g. use pumps and dispensing nozzle for transfer of fuel, use drip trays etc. • Restricted project activities during monsoon. • Carrying out adequate restoration of soil.

4.11 Potential Impact and Mitigation Measures on Road & Traffic During various phases of projects like construction, drilling, early production and decommissioning various types of vehicle / equipment movement would be involved. The vehicular movement is expected would be more in construction/site preparation phase due to movement of machinery & manpower. ONGC would ensure that traffic management plan is implemented so that proper vehicular movement is done with minimal disturbance to nearby communities. The impacts would be for limited duration. Thus, the impacts are temporary in nature and limited mostly within the drill site.

Severity of Impact 2 Extent of Impact 1 Duration of Impact 2 Impact Significance = 4 (low)

Mitigation Measures

• Speed limits would be maintained by vehicles involved in transportation of raw material and drilling rig. • Road safety awareness programs/campaign would be organized in coordination with concerned authorities • Entry of vehicles into the drilling site area is prohibited except for material movement. • Adequate parking would be provided outside the drilling location. 4.12 Potential Impact and mitigation Measures on Terrestrial Ecological Environment Potential impact on terrestrial Ecological environment is envisaged particularly during Site preparation phase and operation phase.

Source of Impact: The Potential Impacts on the existing floral and faunal diversity may arise due to following activities:

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 171

1. Vegetation Clearance. 2. Illumination from Site. 3. Generation of Noise

Impact Assessment:

Vegetation Clearance It is proposed to carryout drilling of development and exploratory wells in Group B (Non-Forest), is in agricultural fields and settlement area. During primary survey, it has been observed that removal of ground vegetation is required for site preparation. The vegetation observed in the study area is common to these climatological conditions and no endangered floral species is observed in the study area. Further the distribution of vegetation is scattered in nature. Clearance of vegetation for site preparation would not require cutting of any mature trees. It is observed that approximately 9 ha land is required for each drill site and clearance of only shrubs and herbs are required. Therefore, the scale of Impact can be considered as low, extent of impact would be limited within site. The clearance of vegetation would initiate the change in land use. So, overall impacts would be low.

Generation of Noise and Illumination from site It is anticipated that noise would be generated particularly during the construction/site preparation period and various operational activities from the drilling site. It is expected to get attenuated to baseline level of noise within 200-300 m from the proposed drilling locations. During the field visit and as confirmed by the Forest Department of Government of Assam, the nearest WLS i.e. Nambor Wildlife Sanctuary is located 6.87 km away and Hoollongapar Gibbon Sanctuary is located at 22.37km away from the nearest block boundary. Therefore, no activity is planned inside the Wildlife Sanctuary area. At the time of field visit it was observed that total land was agricultural field and settlement area. Thus, the potential impacts on existing wildlife due to generation of noise can be considered as low. The drill site would be illuminated during both construction and operational phase as drilling would be conducted continuously for 24 hrs and thus may cause significant disturbance to local faunal population particularly avifauna.

Severity of Impact 2 Extent of Impact 1 Duration of Impact 2 Impact Significance = 4 (Low)

Mitigation Measures A range of measures would be adopted during construction and drilling phase to mitigate the potential impacts of terrestrial ecology and biodiversity which are described below: • The working area would always be kept minimum. • For felling of trees prior approval from concerned department would be obtained; • Appropriate shading of lights would be ensured to prevent unwanted scattering. • Plantation of local trees would be undertaken; • Fencing would be done on the camp site to avoid any unfortunate encounter with faunal species.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 172

4.13 Potential Impact and mitigation Measures on Aquatic Ecological Environment Potential impact on aquatic floral and faunal diversity is envisaged particularly during Site preparation phase and operation phase. During Monsoon, due to the 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 and rivers unless precautionary measures are adopted. Under block boundary Dayang, Chelcheli, Giladhari, Kakodanga river are present. However, provision of onsite drainage system, sediment control measures, provision of oil water separator would aid discharging of surface run off in compliance with the CPCB Inland Water Discharge Standards, the impact is considered would be of low significance. Severity of Impact 2 Extent of Impact 1 Duration of Impact 2 Impact Significance = 4 (Low)

Mitigation Measures • Proper treatment of all wastewater and produced water and any water discharge from well site would comply with CPCB Discharge Standards for Oil and Gas Industries • Waste mud would be stored in the HDPE lined pit • Drainage and sediment control systems at the well site would be efficiently designed • All chemical and fuel storage areas, process areas would have proper bunds so that contaminated run-off cannot escape into the storm-water drainage system.

4.14 Potential Impact and Mitigation Measures on Socioeconomic Environment The impact on different aspects of the socio-economic environment is discussed as under.

Additional Demand on Infrastructure The width of some of the access and approach roads are not wide enough to support the movement of heavy vehicles to drill site, hence they have would be widened and strengthened. Transportation of drilling rig and associated facilities to drill and decommissioning of rig and associated structure would 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 would reduce the significance of impact from medium to low.

Influx of labour Population

Influx of population is anticipated in all stages of the project cycle particularly during exploratory drilling. The drill site would involve the operation of about 50 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, considering that majority of the workforce during construction phase is likely would be sourced from local villages chances of such conflicts are negligible.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 173

Employment opportunities

Project would benefit people living in the neighbouring villages temporarily by creating opportunity for direct & indirect employment associated with the various project activities. Site preparation phase would involve certain number of laborers and there is a possibility that local people can be engaged for this purpose. Drilling process would involve several skilled and unskilled workers. Generation of short time employment opportunities during the project phase would improve the employment scenario of the area.

Cultural & Heritage Site

Impact on cultural environment may occur due to site preparation, operation of drilling rig and also during vehicular movement with respect to the proposed exploration activities. There are no designated historical or cultural spots close to the well sites or access roads hence; no impact in this regard is envisaged.

Corporate Social Responsibility

ONGC has taken up various CSR initiatives in and around present operational areas for the benefit of the residents as per the CSR Act and Rules, Govt. of India. These activities would be further strengthened, and new initiatives would be taken up as per need assessment when the project becomes fully operational. Mitigation Measures • The shortest distance as far as available/feasible would be considered for access road, with additional care to avoid division of land parcels into agriculturally unviable fractions; • The village road identified for accessing proposed project footprints, would be strengthened and widened as per requirement • Appropriate awareness program on grievance redressal mechanism, would be designed and implemented for local community around proposed project footprints;

Impact Significance = ++ i.e. POSITIVE

4.15 Potential Impact and Mitigation Measures on Occupational Health and Safety Impacts on Occupational health and safety during site preparation/construction and operational phases would be as follows: • Operation of construction machineries/equipment; • Exposure to high noise generation areas. • Operation of rig and machineries,

Major occupational health hazards encountered during the drilling as well as other phases of the project would include noise from drilling activity, operation of heavy vehicles and machinery, handling of chemicals etc. Continuous exposure of workers to high noise levels and fugitive dust and inadequate facilities and unhygienic conditions at such camps may lead to adverse health impacts viz. headache, asthma, allergy, hearing loss etc. Another aspect would be safety risks due to handling of inflammable hydrocarbons and incident of blow-outs.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 174

As a part of embedded control Measures, proper PPEs would be provided to the workers onsite. ONGC would also ensure that the working personnel have provision to adequate sanitation facilities, clean drinking water and other necessities pertaining to health & hygiene. Workers would receive training regarding safe working practices and work permit would be issued appropriately for working under specified condition. It would also be ascertained that a maximum of 10 highly personnel are involved in a production facility per shift.

Severity of Impact 2 Extent of Impact 2 Duration of Impact 2 Impact Significance = 8 (Medium)

Mitigation measures: • Periodic onsite surveillance would be conducted so that the workers use the designated PPEs all the time; • Periodic Health surveillance would be conducted of all working personnel • Regular health and safety training would be provided to workers. • Exposure of workers operating near high noise generating sources would be reduced to the extent possible;

4.16 Potential Impact and mitigation Measures on Community Health & Safety Community health and safety of inhabitants residing close to the drilling site is likely to get affected from frequent heavy vehicular movement along village access roads and due to noise from drilling rig operations. The increase in traffic load due to project activities would have implications on their safety too, as well as create congestion, potential delays and inconvenience for pedestrians. Health and safety impact arising from technological emergencies viz. well blow outs, explosions have been delineated in Chapter 7 of the report.

Severity of Impact 2 Extent of Impact 2 Duration of Impact 2 Impact Significance = 8 (Medium)

Mitigation Measures: • Drilling activities would be under proper fencing • Proper hoardings in English and local language would 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 project activities. • Traffic management plan would be developed and implemented at site. • Proper Onsite & offsite management plan along with Disaster Management Plan (DMP) would be in place to deal with emergencies and contain the impact to minimum extent.

5. Analysis of Alternatives

Consideration of alternatives of a project proposal is a requirement for conducting EIA. Analysis of alternatives of key parameters of the project helps to determine the most suitable method for implementing the project with minimum environmental footprint and optimum socio-economic prospects. The following aspects of the project were considered for alternative analysis:

• Site alternatives (e.g. advantage of proposed site, details of any other sites, if explored, etc) • Input or supply alternatives (e.g. use of raw materials, sourcing, etc) • Technology alternatives (e.g. feasibility of different technologies available and advantage of proposed technology, etc)

After analysis of the various factors the most environmentally compatible alternative is selected. Reference may be made to available technologies, policy objectives, social attitudes, environmental and site constraints, projects economic etc. This section provides an analysis of alternatives in relation to the conception and planning phase of the project. 5.1 No Project Scenario The preliminary consideration in alternative analysis is the ‘No Project Scenario’ which indicates the pros & cons with respect to environmental & socio-economic status of the locality & the region if the proposed development drilling of hydrocarbons and production of hydrocarbon are not conducted in the area.

In such a scenario, there would not be additional stress on the infrastructures & local resources and negative environmental footprint on baseline environmental Aspects viz. air, water, noise levels, soil and ecology of the area. However, there would not be any beneficial impact on socioeconomic status of the area due to generation of direct/ indirect employment opportunities and economic developments due to implementation of the project. At the same time, the no project scenario would also cause continuation of Nation’s dependence on import of crude oil and demand for foreign exchange. 5.2 Alternatives for Project Site The PML is allocated by the Government of India under the revenue sharing contract (RSC). ONGC would be the operator for the PML. Drilling locations will be selected based on geoscientific information of the specific Block site available with MoPNG and alternate sites cannot be considered for the proposed project facilities for the above reasons.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 184

5.3 Alternatives for Well Location The proposed exploratory well site will be identified based on the study and interpretation of the stratigraphy and already available seismic data. Within the identified location the actual well drilling site would be selected based on the following factors: • Located as far as possible from the nearest human habitation or sensitive receptors. • Located at a safe distance from public road. • Ensure natural drainage channels are avoided or drainage channels rerouted along the periphery to ensure unhindered flow of rain / flood water. Wherever necessary adequate erosion control measures would be provided. 5.4 Alternative of Technology The technical and process related alternatives are discussed below:

Use of Water Based and Synthetic Based Mud Drilling mud is used during drilling operation to lubricate and cool drill bits, remove drilled rock (i.e. cuttings) from the bottom of the hole and transport it to the surface and maintain hydrostatic head in the well to counter natural formation pressures. Drilling mud is basically a suspension / mixture of solids suspended in a liquid phase, which is blended with clays, polymers, salts and weighting agents. The main component/ solvent of drilling fluid is water, oil or synthetic and accordingly named oil-based, water-based and synthetic-based muds (OBMs, WBMs, and SBMs). All the three types of muds have certain advantages and disadvantages as discussed below. Table 5-1 Contents of the Report Aspects WBM OBM SBM Least cost 1 2 3 Quantity of waste discharge 3 2 1 Least amount of water 3 2 1 required for preparation Toxicity 1 3 2 Reduced drill time 3 2 1

Note: 1- Preferable, 2 – Less Preferable, 3 – Least Preferable The WBMs is a least cost option and widely used but is not found efficient in high temperature and also for water sensitive substrata, i.e., shales and mud. Both SBM and OBM are more efficient in their use than WBM but possess significant environmental hazards regarding their disposal. OBM are considered toxic due to the use of hydrocarbons as solvents and need a proper disposal through engineered

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 185

land fill. SBM has also issues related to biodegrability when it comes to its disposal and safe to be disposed in lined pits.

Hence, If all the three types of mud are compared for its use, OBM is not considered for its toxicity. SBM is superior in terms of its operation than WBM but considering the environmental point of view, WBM would be used for normal drilling operation by ONGC. 5.5 Conclusion ONGC would ensure that the final selection of well locations is made after due consideration the nearest habitation, proximity to any sensitive receptor and natural drainage and all environmental conditions as mentioned earlier. Also, technology with least environmental footprints would be adopted to the extent possible. Consideration of these alternatives with strict compliance to the Environment Management and Monitoring Plans suggested in the next chapter would ensure minimal adverse impact on the Environment.

6. Environmental Monitoring Programme

Assessment of environmental parameters and status & effectiveness of the Environment Management plan (EMP) is most effectively done through Periodic monitoring of environmental parameters during pre-drilling, drilling and post drilling stages. A properly planned monitoring programme would serve as an indicator for any deterioration in environmental conditions due to operation of the project, enabling taking up suitable mitigatory steps in time to safeguard the environment. Monitoring has equal implication as pollution control in environment management of a Project since the efficiency of control measures can only be determined by monitoring.

An Impact Assessment study is usually carried over short period of time and the data cannot bring out all variations induced by the natural or human activities. Therefore, periodic monitoring programme of the environmental parameters is essential to consider the seasonal variation and changes in the environmental quality due to project operations. 6.1 Objective of Monitoring The objectives of monitoring are to:

• Verify effectiveness of planning decisions; • monitor the efficiency of control devices & other mitigation measures • Measure effectiveness of operational procedures; • Confirm to statutory and corporate compliances

• Identify unexpected changes to provide remedial measure swiftly

6.2 Monitoring Schedule Periodic environmental monitoring schedules are prepared covering various phases of project comprising of proposed exploratory drilling as well as post-drilling phase, when the hydrocarbon is established in the wells and production program is undertaken as well as the Decommissioning/Closure Phase. In order to assess the extent and nature of impacts on environment due to drilling operations, the monitoring on various attributes of environment would be carried out during various phases of drilling as under:

The Environmental Monitoring Program comprising of parameters to be monitored, proposed monitoring location and frequency of monitoring is presented in Table 6.1 below.

7. Additional Studies

Based on the TOR specified by the Ministry of Environment & Forest and Climate Change (MoEF&CC) issued vide letter no. F. No. IA-J-11011/86/2019-IA-II(I) dated 14 Apr 2019 for preparation of EIA/EMP Report for proposed project, the following additional studies, as suggested in EIA Notification, were conducted:

• Risk Assessment Study

• Disaster Management plan

Public Hearing and Consultation would be conducted based on this draft report. The suggestions and issues received during the public hearing would be addressed suitably and incorporated in the Final EIA report, for onward submission to EAC of MoEF&CC for obtaining the Environment Clearance (EC). 7.1 Risk Assessment Risk” is defined as the combination of the expected frequency and consequence of accidents that is caused by a hazard. A risk assessment (RA) is a systematic approach of identifying objects, events or processes that may cause harm or hazard to people, environment and asset or property. After identification of hazards, the severity of the risk is evaluated, and measures are suggested to effectively eliminate or control the hazards. This process of control usually involves monitoring, re- evaluation, and compliance with decisions

RA are crucial as they form an integral part of an occupational health and safety management plan. RA play a vital role in the following aspects:

• Create awareness of hazards and risk. • Identify who may be at risk • Determine whether a control program is required for a particular hazard. • Determine if existing control measures are adequate or if more should be done. • Prevent injuries or illnesses, especially when done at the design or planning stage. • Prioritize hazards and control measures. • Meet legal requirements where applicable.

In the present context, the scope of RA study includes the following:

• Identification of hazards arising in the proposed projects • Identification of potential risk scenarios that may arise from the identified hazards. • Consequence prediction of potential risk scenarios if consequences are high, establish the same by through application of quantitative simulations.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 190

• Recommendation of feasible preventive and risk mitigation measures as well as provide inputs for drawing up of Emergency Response Plan (ERP) for the project.

Hazard Identification includes investigation of all events or processes which could result in possible adverse impacts on people, environment & equipment. On identification of potential incidents of hazards, its risk potential is assessed.

Drilling rig floor is the core area of exploration and development projects and extremely susceptible to accidents. Safety precaution with utmost care is required to be taken during drilling as per the prevailing regulations and practices so that accidents can be avoided. Due to advancement in technology, number of equipment has been developed over a period to cater the need of smooth operation on a rig floor. Various standards are required to be referred to cover the variety of equipment used for safe operation in drilling and it is desirable to use a properly prepared manual for occupational safety while working or drilling over a rig. It may, however, be noted that well testing and production testing of hydrocarbons also require proper analysis of hazards involved in production testing operations and preparation of an appropriate Emergency Control Plan. Hydrocarbon Operations are generally hazardous in nature by virtue of intrinsic chemical properties of hydrocarbons or their temperature or pressure of operation or a combination of them. Fire, Explosion, Hazardous Release or a combination of these are the hazard associated with Hydrocarbon Operations

Risk assessment is measured by the risk potential which is factored by the likelihood of occurrence of an event and its probable Impact.

The likelihood of occurrence is measured using the following relative scale.

Rating Likelihood Description 1 Very Low Highly unlikely to occur. May occur in exceptional situations. 2 Low Most likely will not occur. Infrequent occurrence in past projects. 3 Moderate Possible to occur. 4 High Likely to occur. Has occurred in past projects. 5 Very High Highly likely to occur. Has occurred in past projects and conditions exist for it to occur on this project. The scale of impact is defined as follows:

Rating Impact on People Impact on Asset Impact on Business Schedule

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 191

Rating Impact on People Impact on Asset Impact on Business Schedule 1 No significant impact No impact No change in schedule

2 Physical injury requiring Temporary damage < 1-week delay to first aid to equipment schedule 3 Physical injury leading Significant but 1 - 2 weeks delay to urgent medical aid, other temporary address schedule health impact to equipment 4 Critical injury causing Critical damage to 2 - 4 weeks delay to significant physical injury equipment leading schedule and other health impact o disruption in operation for a time period 5 Irreversible impact on Permanent > 4 weeks delay to human health, death damage to schedule equipment leading to temporary suspension of operation

The level of risk using the likelihood of occurrence & its impact is presented in the matrix below:

Events having major risk need identification and immediate attention for its mitigation, whereas events with moderate risk also need adressal and plan to mitigate its impact. The types of hazardous events along with its risk potential for the proposed projects are presented below. The risk assessment has been done considering the embedded mitigation & management measures.

Consequence Modelling

Consequence models are used to predict the physical behaviour of hazardous incidents. Important inputs to the Consequence analysis calculations include the weather conditions and the damage criteria, both of which are discussed in the following.

Weather Conditions

The weather stability class considered is Class C/D for day time and Class F for Night time. The average wind speed most of the time is 5 m/s for day time and 1.5 m/s at night time. combining this with the before mentioned stability classes,

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 194

consequence modeling is done for both these weather cases. The ambient condition considered in this study is as under:

Average Ambient Temperature = 32˚C Average Humidity = 80 (%)

The six representative weather classes considered to determine the inputs are detailed in the table below:-

Day time conditions Night sky Strength of sunlight Surface wind speed Strong Moderate slight Thin ≤3/8 (m/s) Overcast ≥ Cloudiness

4/8 Cloudiness** <2 A A-B B E F 2-3 A-B B C E F 3-5 B B-C C D E 5-6 C C-D D D D >6 C D D D D

*Applicable to heavy overcast conditions day or night **Degree of Cloudiness = Fraction of sky above horizon covered by clouds. A- Extremely Unstable Conditions B- Moderately Unstable Conditions C- Slightly Unstable Conditions D- Neutral Conditions* E- Slightly Stable Conditions F- Moderately Stable Conditions

In its original form, the Pasquill system contains seven categories (A to F) but joint categories are also common. Categories A (Very Unstable), D (Neutral) and F (Very Stable) are discussed next.

Category A (very unstable) occurs typically on a warm sunny day with light winds and almost cloudless skies when there is a strong solar heating of the ground and the air immediately above the surface. Bubbles of warm air rise from the ground in thermals. The rate of change (decline) of temperature with height (lapse rate) is very high.

Category D (neutral) occurs in cloudy conditions or whenever there is a strong surface wind to cause vigorous mechanical mixing of the lower atmosphere.

Category F (very stable) occurs typically on a clear, calm night when there is a strong cooling of the ground and the lowest layers of the atmosphere by long wave radiation. There is a strong inversion of temperature (i.e. warm air over cold air).

Damage Criteria

Jet Fire

The term jet fire is used to describe the flame produced due to the ignition of a continuous pressurised leakage from the pipe work. Combustion in a jet fire occurs in the form of a strong turbulent diffusion flame that is strongly influenced by the initial momentum of the release. Flame temperatures for typical jet flames vary from 1600°C for laminar diffusion flames to 2000°C for turbulent diffusion flames. The principal hazards from a jet fire are thermal radiation and the potential for significant knock-on effects, such as equipment failure due to impingement of the jet fire.

The consequence caused by exposure to heat radiation is a function of: • The radiation energy onto the human body [kW/m2]; • The exposure duration [sec]; • The protection of the skin tissue (clothed or naked body).

It can be assumed that people would be able to find a cover or a shield against thermal radiation in 20 seconds time. Furthermore, 99% lethality may be assumed for all people suffering from direct contact with flames. The effects due to relatively lesser incident radiation intensity are given below. In the study, the following criteria were used for estimation of heat radiation due to jet fire fatalities: Incident Damage criteria Radiation (kW/m2) 4.0 Will cause pain in 15 to 20 seconds and injury after 30 seconds’ exposure 12.5 ➢ Significant chance of fatality for medium duration exposure. ➢ Thermal stress level high enough to cause structural failure. ➢ Wood ignites after prolonged exposure. 37.5 ➢ Significant chance of fatality for people exposed instantaneously. ➢ Cellulosic material will pilot ignite within one minute’s

exposure Source: OGP

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. In the study, the following criteria were used for estimation of heat radiation due to pool fire fatalities:

Incident Radiation Damage criteria (kW/m2) 4.0 ➢ Escape action within 1 minute ➢ Caused second degree burn within 60 seconds 12.5 ➢ Escape action within few seconds. ➢ Caused second degree burn within 40 seconds. 37.5 ➢ Results in immediate fatality. ➢ Pain threshold is instantaneous leading to second degree burns within 8 sec.

Overpressure effect Overpressure criteria is presented below:

Overpressure level, bar Effect on Assets & human 0.01 – 0.07 Glass damage resulting to cracking and shattering 0.07 – 0.17 Repairable damage to buildings, Chances of effect on human hearing & injuries from flying objects 0.17 – 0.35 Heavy damage to buildings & equipment, serious hearing disabilities & wounds from flying objects, Chances of lethalities

Identification of Major Hazardous Substances The bulk storage in the unit involves the storage of High-speed diesel in the site and the details are as follows: Material Physical State Storage capacity Hazard High speed Diesel Liquid 42 KL Pool fire, explosion (HSD)

HSD would be stored in an atmospheric storage tank, but the placement of the HSD storage unit has not been confirmed yet. So, as per professional judgment of the consultant, the placement of HSD tank and storage capacity of the tank has been decided.

There is a possibility of failure associated with each mechanical component (vessels, pipes, pumps or compressors) etc. These are generic failures and can be caused by such mechanisms as corrosion, vibration or external impact (mechanical or

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 197

overpressure). A small event (such as a leak) may escalate to a bigger event, by itself causing a larger failure. The range of possible releases for a given component covers a wide spectrum, from a pinhole leak up to a catastrophic rupture (of a pipeline) or full-bore rupture (of a pipe). It is both time consuming and unnecessary to consider every part of the range; instead, representative failure cases are generated. For a given component these should represent fully both the range of possible releases and their total frequency. In line with previous similar projects executed and per the standard approach and guidelines, the following typical types of failures are considered for the different isolatable sections: -

Description of section Scenarios HSD storage vessel ➢ Partial release of containment - 20 mm leak ➢ Complete release of containment

For each identified failure case, the appropriate data required to define that case is input into the model. An estimate of the failure frequency is assigned to the failure cases, which is based on the published database in March 2010 of International Association of Oil & Gas Producers (OGP). When the appropriate inputs are defined, the model calculates the source terms of each release, such as the release rate, release velocity & release phase. The results of consequence modelling from various scenario of release from HSD storage vessel is presented below:

For the intensity level of 37.5 kW/m2, maximum downwind distance of impact would be 64.67 in case of complete release of HSD. 7.2 Disaster Management Plan The Offsite & Onsite Disaster Management Plan (DMP) and Emergency Response Plan (ERP) are available for existing facilities in the asset, which would be extended to proposed activities. The scope of the DMP On-site Emergency Preparedness Plan is to evaluate the various types of emergencies that can occur during Drilling and Production activities and to formulate emergency plans, procedures that can be implemented by ONGC in house. In case the impact of the contingency extends beyond ONGC’s capability, the off-site Emergency plan shall be activated simultaneously with the help of District administration.

The following are the main objective of Disaster Management Plan:

• Safeguarding lives both at installations and in neighbourhood. • Containing the incident & bringing it under control. • Minimizing damage to property & environment. • Resuscitation & treatment of causalities. • Evacuating people to safe area. • Identifying persons and to extend necessary welfare assistance to causalities. • Finally, when situation is controlled, efforts are to be made to return to normal or near normal conditions.

─ In coordination with In charge Fire, arrange to take all steps to control emergency situation. ─ Closely monitor the emergency situation and change action plan as per need ─ In case of Major / Serious Emergency arrange to blow all clear siren when the emergency situation is under control.

Key personnel for respective services, depending upon the nature of the emergency shall arrive at the site to take charge of their respective positions such as Logistics Coordinator, Safety (HSE) Coordinator, Fire Coordinator, Finance Coordinator, Medical Coordinator, Communication Coordinator etc.

7.2.4 Emergency Control Room (ECR) at Base office An emergency control room (ECR) will be set up at base office in radio room under the control of Chief Emergency coordinator (CEC). Management decisions and plans will be conveyed from ECR to emergency site by AEC. From Site Control Room (SCR) all developments at emergency site will be communicated to ECR at base.

7.2.5 Responding to an Emergency The procedures for combating emergency situations viz. Blowout at a rig, release of toxic gases in an uncontrolled manner, fire or explosion are defined as emergency procedures. There are written laid out action sequences to be followed while fighting an emergency. 1. A person who detects say a fire, an explosion or a leak of hazardous gas should shout “Fire, Fire, Fire” Help, Emergency as applicable” and communicate the event to the people all around and to Shift I/C by using fire alarm / bell. 2. Should attempt to control or contain the emergency with the available resource if possible. 3. The emergency actions are put into action immediately by the Shift In-charge / Tool Pusher / Rig Manager, who then assumes the role of On Scene Coordinator (OSC). 4. He then accesses the nature of emergency and informs AEC regarding requirement of crisis management team if any to mitigate the emergency. 5. The “Crisis Management Team” arrives at the scene and joins hands with the site crew, other supporting team to further combat the crisis under the guidance of the OSC and AEC. 6. A buddy team is created from the available manpower and kept as standby to the main team.

7.2.6 Emergency Procedures in the Event of Blowout

A blow out situation is a consequence of uncontrolled flow of oil / gas and there is every likelihood of fire being triggered off. To tackle such an emergency situation the flow of action can be divided into following two steps.

Step - I : Action on the spot - On-site. Step - II: Action of Asset in co-ordination with Basin.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 205

The various functions regarding these steps have been elaborated in the form of action flow sequences and kick control procedures. With a view to avoid overlapping of functions, the various actions required to be taken during a blowout have been identified and the personnel responsible for taking actions have been specified. The position of blowout well being different in different cases the exact action plan of work to control the blowout spill / blowout fire and for capping of the well would be finalized by competent authorities of the Asset / Basin / Headquarters.

Functions of On-Scene Coordinator (OSC):

The OSC will take charge of the situation at the rig and follow the standing instruction given below ▪ Evacuate all personnel to safe site. Switch off engines and generators. ▪ Remove and secure all well records. ▪ Avoid and extinguish all naked flames / sparks. ▪ Pull out all inflammable materials i.e. HSD, Petrol, Gas Cylinders, Chemicals etc. from well premises. ▪ Pull out all possible equipment to safe distance. ▪ Start spraying water on well mouth to keep it cool. ▪ Cordon off the area and do not allow entry of any unauthorized person. Allow only the persons directly involved in operations to go near blowout well and maintain record of such persons. ▪ Intimate Emergency Control Room (ECR) at base for deployment of additional manpower, materials, logistics / transport arrangements and technical support if any. ▪ Keep in touch with ECR through Site Control Room (SCR) for update, feedback and instructions from base. ▪ Assign responsibilities to the concerned persons to control the situation. ▪ Evacuate all equipment and materials to safe location if required. ▪ Make record of following information for forwarding to Emergency Control Room (ECR) at base: ─ Well condition. ─ Position of drill string / Tubing string in the well. ─ Last tubing and annulus pressure recorded. ─ Number, Name and Designation of persons at site, measures initiated to meet the ─ situation, details of injury / casualty, if any.

Emergency procedure for Control of Kick

A kick during drilling or work over operations is an event preceding a blowout. A blowout situation is never sudden and almost always follows several indications or pointers. A kick is sudden outflow or upsurge of the drilling mud or work over fluid due to unexpected encountering of a gas zone or high pressure fluids, which throws out the fluids upwards out of the well bore. The kick of the out flowing fluid needs immediate remedial attention lest it assumes a more dangerous form of blowout. The remedial action by the crew and the kick control procedures are elaborated below.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 206

Duty guidelines for Rig operational crew

All operations will be carried out under the control and guidance of the Shift In- charge / Tool Pusher, who then functions as the OSC. When a kick is detected, the Shift In-charge will give a signal and all members of the crew will take up their respective positions. The signals will be in the form of shortsirens in a continuous manner from the driller’s console.

SHIFT Stand on brake and control as necessary. Supervise all activities to INCHARGE control the situation. Ensure functioning of BOP and choke manifold (SIC) lines.

7.2.7 Offsite Emergency Plan The OFF-SITE Emergency Plan for existing processing/production facilities of PML areas in ONGC, Assam Asset is a compilation of various emergency scenarios. It also includes the probable impact on “off the site‟ due to emergency and the action plan to combat / mitigate the consequences of a disaster situation.

7.2.8 Assessment of Hazard leading to Off-Site Emergency The hydrocarbons produced from the seven PML locations in Golaghat & Jorhat districts would be was transported to the nearest Gas Gathering Station (GGS) via pipeline. The equipment at the installation mainly consist of bank of separators, storage tanks and oil dispatch pumps. Fire is the most common hazard in a Crude Oil and Natural Gas processing operations and there are also possibilities of explosion and toxic gas dispersion which can arise due to the severe operating and storage conditions. Any incident of the above nature is likely to cause extensive damage to the plant property and personnel.

Outside the premises of these installations, environmental hazards are likely to occur due to the leakage / bursting of either trunk pipeline or flow lines from wells and flaring of natural gas.

Hazard in Flow Lines: A pipeline connecting one installation to another installation is termed as a trunk line while a pipeline connecting hydrocarbon well to the installation is called as a flow line. The trunk pipeline and almost all the well flow lines pass through the agricultural fields. The trunk and flow lines are sub-surface pipelines and are laid about 1.2 m below the ground level. Due care would be taken during laying of trunk and flow lines. As far as possible laying of pipeline would be avoided in populated area. The main risk in transportation of oil / gas through pipeline is leakage of oil / gas which may result in fire if source of ignition is present.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 209

Once, detected, the emergency procedure will be activated and remedial action will be taken to control the leak, spread of fire etc.

Hazard during transportation by tankers: Initially the oil is transported through road tankers from the development sites to the nearest GGS. There is a chance of oil spill due to overturning or collision of tankers. In this case, a small quantity of crude oil is likely to be spilled. When an emergency arises the nearby police station may be contacted to cordon off the affected area and all sources of ignition are removed to safe distance to avoid fire. Nearby public would be instructed not to light any source of ignition. Efforts should be made to stop the flow of oil into nearby water bodies to avoid water contamination. For this purpose, improvised booms made of bamboo‟s plants etc. may be rigged up to contain the oil and prevent its spreading.

Other than above technical and operational hazards ONGC units also poses disasters due to man-made causes such as Terrorist attack, Bomb threats. The action plan for these scenarios is as below:

a. IED Attack

Primary rule If a suspected device is encountered, it should not be handled, and the area should be secured. Improvised explosive devices are very unstable. They are extremely sensitive to shock, friction, impact, and heat, and may detonate without warning. Even the smallest devices can cause serious injury or death.

Secondary rule • Always assume that there is more than one device present, whether any other bomb or a device has been located. • Package-type IEDs: Institute security procedures in receipt and dispatch section and instruct employees on how to recognize suspicious packages. • Luggage-type IEDs: Train security personnel and employees regarding unattended packages of any type. Never pick up or open any suspicious package or piece of luggage. If an IED is discovered, call the police and do not touch the device. • Vehicle-borne IEDs: Perform a vulnerability/threat assessment for the facility with special attention to this type of explosive delivery mechanism. Consider the use of enhanced security away from your key buildings (such as a vehicle checkpoint) or the use of bullards or barriers to block vehicular access to building entrances.

b. Chemical Attacks A chemical emergency occurs when a hazardous chemical has been released and has the possibility of harming people‟s health. Potentially lethal, chemical agents are difficult to deliver in deadly amounts. If released outdoors, the agents often dissipate rapidly. As such, the most lethal area for a chemical release is inside a confined space, such as a building, public place, or subway system.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 210

Industrial chemicals, while not as lethal, can be just as effective if released in sufficient quantities. Chlorine, ammonia, benzene, and other toxic chemicals are routinely transported through densely populated areas in rail tankers or truck tankers and could be the target of a terrorist attack.

Chemical terrorist attacks will most likely be overt because the effects of most chemical agents are immediate and obvious. Your response will have to be thought out and practiced in advance to be effective.

Evacuation Some types of chemical emergencies will require evacuation from the immediate area. If you are up-wind and in the open, evacuate up-wind and away from the incident. Cover your mouth and nose with a damp cloth. If you have been exposed, you will have to be decontaminated by first responders. Shelter in Place If you are already in down-wind and/or in a multi-story building, you may be instructed to shelter in place or to make that decision on your own. Most likely you will only need to shelter for a few hours. The procedure includes: ─ Go inside as quickly as possible shut and lock all windows and doors; turn off all HVAC equipment and any fans. ─ If you have multiple floors, go as high as practical, three to five floors. (Most chemical agents are heavier than air.) .If you have duct tape, tape over door and window cracks, vents, electrical outlets, and any opening to the outside. ─ Wait for instructions from first responders before leaving. c. Biological Attacks A bio-terrorist attack could happen in any workplace, yet most company personnel know little about potential bio-toxins or bio-pathogens or how to recognize these agents and respond in the event of an attack.

There are several ways a bio-terrorist event may manifest itself. The biological event may result from a covert attack. A covert attack may be unleashed by the receipt of an object, such as a package or piece of mail, accompanied by a warning or threat. Biological agent release also could occur via the ventilation system (HVAC) in a building, where dispersal could take place within a matter of minutes. Because the covert release is not witnessed, the effects of such an event can be widespread and difficult to isolate or recognize. While terror is intended to produce casualties, disruption, and fear, the use of biological agents is particularly injurious.

Biological attacks are delayed events. The sudden appearance of generalized symptoms in victims who present themselves to medical providers may initially disguise the true source of exposure. Only when a trickle of patients turns into a flood or mysterious pathogens quickly make their presence felt does the magnitude of the event reveal itself. The goal of the medical care community (i.e., hospitals, physicians, and other health care providers) is to recognize and diagnose the disease (which frequently may be unfamiliar to most clinicians) and to provide treatment. The goal of public health authorities is to detect and control the outbreak of the illness. Public health officials will focus on identifying and treating exposed persons and preventing the spread of disease. In response to a covert release, it is

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 211

important for ONGC health officials to recognize the signs and symptoms of an emerging disease among employees.

If an overt release is recognized, take immediate action to isolate the exposed employees and/or area of agent dispersion and to remove others from the area of release. Notify local public health authorities immediately and follow their directions. Decontamination may also be warranted in response to an overt release.

d. Radiological Attacks

A radiological weapon or “dirty bomb” is a crude device that combines a conventional explosive with highly radioactive material. When detonated, the blast vaporizes the radioactive material and propels it across a wide area. The main danger from a dirty bomb is the initial blast, which could cause serious injury or property damage. The radioactive materials will likely not be concentrated enough to cause immediate serious illness, except to those very close to the blast site or those who inhale smoke and dust. Dirty bombs are designed to cause tremendous psychological damage by exploiting the public’s fear of radiation. These are not weapons of mass destruction, but weapons of mass disruption aimed at wreaking economic havoc by making target areas uninhabitable for extended periods. There are three basic ways to reduce the exposure:

• Reduce the time near the source of radiation, • Increase the distance from the source of radiation, • Increase the shielding between person and the source of radiation. Shielding is anything that puts distance and mass between person and the radiation source.

Evacuation

If a person is outside, evacuate up-wind from the blast site cover the nose and mouth with a wet cloth to reduce the risk of inhaling radioactive smoke or dust. Once out of the immediate area, seek shelter and wait for instructions from first responders. If individual has been exposed to dust or smoke, follow the decontamination procedure. Shelter in Place If a person is close to the blast and inside a building, stay inside if the building is intact. Move to the basement and turn off all HVAC equipment and fans bringing in outside air it is not necessary to seal doors and windows, but it may be helpful. Wait for instructions from first responders.

7.2.9 Reporting of an Off-Site Emergency The off-site disaster management plan will be put into action in the following situations: a) In case of an Onsite emergency spreads beyond the boundary of installation and causes damage to the life or property outside the boundary. b) In case an emergency originated from outside the premises of the installation/Drilling Rig/Work over Rig which is likely to effect the operations of installation.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 212

The off-site emergency requires mobilization of resources beyond ONGC capabilities such as state emergency services. In case of an off-site emergency, the On-site Chief emergency coordinator (Asset Manager) will report the matter to the District Collector, who is Chairman of District emergency committee. Further, the Chairman will mobilize other members of District Emergency committee as per the organization Chart for an Off-site emergency management presented in the figure below.

Figure 7-2 Offsite Emergency Management flowchart

Communication to Corporate Disaster Management Group (CDMG)

The Chief Emergency coordinator shall immediately inform CMD, Director (HR),- CCEC, Director-concerned and Director-I/C HSE on the situation and his assessment for intervention of Corporate Disaster Management Group (CDMG).

Functions and responsibilities of emergency Committee

When a call is received from On-site Emergency coordinator regarding emergency / disasters, District Collector of district, who is also chairman of the District Emergency committee, will initiate the district level action plan to combat the emergency. Responsibilities of Chairman of District Emergency Committee

i. Take overall responsibility for combating the off-site emergency. Declare an area of 500 m or up to 1.5 Kms as felt appropriate around the site as a “Hazardous Zone”.

7.2.10 Mock Drill for Onsite and Off-Site Emergency Management ONGC may conduct Mock Drill to check the efficacy of Onsite and Off-site Emergency plan for review and updation in association with Government officials. Once in every year this plan will be practiced on field mock exercise involving dramatized scenarios to test the communication system, action plan and response of

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 214

all Key agencies within ONGC and Government officials. Such on field mock exercise will be selected from high risk areas and near real approach of actual firefighting / evacuation operations will be undertaken. An emergency will be alerted through different types of Siren Sound Code example fire, explosion, toxic release etc. Siren codes as per OISD STD 116 reproduced in the table below will be followed.

Emergency Siren Codes Scenario Siren Sound Code Major Fire A waiting siren for 2 minutes. Siren should be sounded 3 times for 30 seconds with an interval of 15 seconds Disaster Same type of siren as in case of Major Fire, but the same will be sounded for 3 minutes with an interval of 2 minutes Gas Leak A wailing sound for 2 minutes, 5 times for 20 seconds at 5 seconds interval Blow-out with Same as “Major Fire”siren Fire Blow-out “Same as “Gas leak” siren without Fire Air raid As per guidelines of Air Defence department of the area All Clear Straight run siren for 2 minutes Test Run Straight run siren for 2 minutes

Note: Sound for Gas situation and blow-out sirens have been devised internally, as it is not mentioned in OISD-116. During mock drill exercise observers would be appointed in key areas to take note of individual responsibilities, response time and lapses. Every mock exercise will be followed by “post – mock-drill meeting” to discuss the findings of observers and shortcomings. The lessons learnt from such exercises will be summarized in the form of a report to improve upon the overall preparedness and will also be used as inputs for updating the plan to the extent necessary. If in any case the exercise cannot be carried out due to operational reasons the same shall be done as the table top exercise to test the communication system, action plan and response of all Key agencies within ONGC and Government officials.

Review of the Plan The off-site emergency plan will be reviewed by ONGC and District Emergency Committee as per requirement and updated accordingly.

7.2.11 Leakage of H2S Gas Hydrogen sulphide is a colourless, flammable, extremely hazardous gas with “rotten egg” smell. Low concentrations of H2S irritate the eyes, nose, throat and respiratory system e.g. burning / tearing of eyes, cough, and shortness of breath. Repeated or prolonged exposures may cause eye inflammation, headache, fatigue, irritability, insomnia, digestive disturbances and weight loss.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 215

The Occupational Safety and Health Act (OSHA Regulations) set a 10 ppm ceiling for an eight hourly continuous exposure (TWA limit), a 15 ppm concentration for Short Term Exposure Limit for 15minutes (STEL) and a Peak Exposure of 50 ppm for 10 minutes

The preventive measures to be taken up in case of presence of H2S in geological formation, appropriate mitigation measure will be taken up: • Stop the source of leakage (i.e. close the well) • Remove victim, if any to fresh air, if breathing, maintain victim at rest & administer oxygen, if available, if person is not breathing, start artificial respiration immediately or start mechanical/ automatic resuscitator. Call ambulance and sent victim to hospital or doctor. • Avoid & extinguish all naked flames • Pull out all inflammable material i.e. HSD, Gas Cylinders, Chemicals etc. from the premises of well / installation. • Pull out all possible equipment to safe distances. • Call for fire tender and start spraying water on the sources of leakage to dissolve H2S in water. • Evacuate personnel in 500 m area from down wind direction. • Warn nearby inhabitants, if required. • Cordon off the area & do not allow entry of any unauthorized person. 7.2.1 Oil Spill Minor Oil Spill

There exists a possibility of Hydrocarbon (gases / oil) getting released due to some unavoidable incidents during the Drill Stem Testing. Spillage may occur from lines, valves and separator or due to tank failure. Once the flow of Oil / Gas from well is stopped, then on-site access for clean-up is possible.

Major Oil Spill

A major spill can arise as a result of an uncontrolled flow from a well i.e. Blowout. Provided that ignition does not take place and the well head is not obstructed the well can be shut in at the wellhead.

7.2.2 Blow Out Contingency Plan The Contingency Plan for Blowout is shown in the figure below.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 216

Figure 7-3 Blowout contingency plan

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 217

8. Project Benefits

The proposed project would establish the potential of hydrocarbons in the Block. The development of the oil Block would result in considerable growth of service sector and would also generate direct/indirect employment and business opportunities in the area. The major benefits of the project include reduction of the oil import bill of the nation as well as reduction of the disparity between oil production and consumption.

The commercial development would also lead to investment in Assam, bringing oil and gas revenues both to the State and to the Central Government. The sustained presence of ONGC in the region would substantially improve the socio-economic conditions of the region. There would be generation of employment opportunity for local people as contract/daily wages in nearby areas. 8.1 Revenue Earning of Central & State Government

The 7 PML areas namely Borholla ML, Titabor ML, Mekrang ML, Golaghat Extn IIA (addl) ML, Golaghat Extn IIA ML, East Lakhibari Extn. ML and Kalyanpur ML covers respectively 32.12 sq. km, 10 sq.km, 16 sq. km, 61 sq. km, 24 sq. km, 49 sq. km and 40 sq. km of South Assam Shelf Block in Jorhat and Golaghat district, Assam. It is planned to generate 53 nos. of locations for hydrocarbon exploration & development as the proposed project. It is expected that drilling of these locations will augment the production of hydrocarbons in the present scenario of growing demand of oil and gas in the country. Due to hydrocarbon discovery and its production, use & sell, the central as well as state government would be benefited through revenue earning and sharing.

8.2 Employment Potential

The employment of local people in primary and secondary sectors of project shall upgrade the prosperity of the region. In case the hydrocarbon is established in the Block, there would be establishment & augmentation in local businesses like hotels, restaurants, transport services, medical facilities, supermarkets, etc that would benefit considerable number of people. Hence, the direct & indirect generation of employment would improve the socio- economic conditions of the area.

8.3 Peripheral Social Development The proposed exploration and development of hydrocarbons would lead to augmentation of existing physical & social infrastructure and development of new infrastructure in the region within the purview of part activities, Corporate Social Responsibility (CSR) and Corporate Environment Responsibility (CER) by ONGC. There would be improvement in the road network, Arranging provisions in schools & education centres, medical centres and other institutions in line with the Need assessment survey in the area.

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 224

Phase Mitigation Measures • Top soil will be stored properly for preservation. • Drip trays would be used during vehicular/equipment maintenance and during refueling operations. Drilling • Fuel and chemical storage areas would be paved and properly bunded. • Spill kits would be made available at all fuel and chemical storage areas. All spills/leaks contained, reported and cleaned up immediately. • Drip pans/trays would be used in areas identified having spillage potential but not limited to drill rig engine; electric generator engine; pumps or other motors; maintenance areas; fuel transfer areas. • Management of drill cuttings, waste drilling mud, waste oil and domestic waste would be made in accordance with “Waste Management Plan” Decommissioning/Site Closure • Decommissioning at the end of project life/drilling would have some adverse impacts in terms of increase in soil erosion and would require adequate mitigation measures to minimize any adverse impacts. The mitigation measures would be similar to those outlined for construction phase activities as discussed earlier.

9.6 Spill/Release Management Plan Potential spill / release scenarios Spill incidents from drilling activities can be classified into three types based on the level of response required. A description of the three types are as follows:

Type 1

A small oil or chemical spill incident which can be responded to and controlled with the existing resources, equipment and resources at the site and without any further escalation. Most of the potential drill stage spill risks are Type 1 spill / release incident as the volumes involved are limited due to the extent of hydrocarbons or chemicals used or stored at site. Such possible incidents are likely to include:

• Diesel spills from refuelling i.e., drill rig ‐ hose leaks, overfilling or connection/disconnection incidents. • The use of liquid chemicals i.e., during drilling the volumes are limited by the storage containers used, drums etc. • Hydraulic oil spill resulting from a split hydraulic hose or failed connector (moderate pressure, low volume lines).

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 225

• Drilling fluid leaks from tanks, pumps or other associated equipment within the closed loop recirculation system.

Type 2

Type 2 spill / release incidents are those that are beyond capability of the immediate resources on‐site to effectively manage and contain, requiring additional external resources to assist with the response to the spill incident. Type 2 spill incidents may require initiation of Emergency operations and would involve calling out the Fire Service (in the event of danger to people) and/or regional resources. For such potential spill incidents, the resources of the local administration or suppliers may be required. Such possible incidents are likely to include:

• Transportation incidents associated with the delivery of diesel or drilling fluids to site i.e., truck rollover or collision from external suppliers (drilling fluids and diesel). • Complete failure of an on‐site drilling fluid (base oil) storage tank(s).

Type 3

Type 3 spill / release incidents are significant spill incidents that escalate from a Type 1 or 2 and exceed the capabilities of the on‐site and local administrative resources to respond, requiring a State /National response. An uncontrollable well blow out scenario would fall into this category.

Spill / Release Response Strategies

Spill / release response strategies for combating spill / release incidents include: • Prevent or reduce further spillage. • Monitoring and evaluation (no active intervention but the spill is under observation). • Mechanical containment and recovery.

• Any combination of the above strategies. A brief explanation of these various response strategies is provided in the following sections.

Prevent or reduce a spill / release incident

One of the first response actions, if safe to do so, is the isolation or prevention of the source of the spill / release to limit any further discharge. Such first response actions can involve an emergency shutdown of the particular equipment, isolation of a valve or line causing the spill or providing some immediate containment to prevent the further spread of a spill / release. Such measures are only a first immediate response prior to a more coordinate effort being planned and undertaken.

Monitoring and Evaluation

ONGC Draft EIA Study for Onshore Development and Production of Oil & Gas for 53 Wells in 7 PML blocks February, 2020 AECOM 226

─ Knowing the position of spillage / release source and having the ability to forecast its movement or direction is an essential component of spill response. Monitoring and evaluation is used to: • Determine the location and movement of the spill / release (if any). • Describe its appearance. • Estimate the size and quantity of the spill / release • Note changes in the appearance and distribution of the spill over time.

• Assess the potential threat to the environment and the resources required to combat the spill / release (more effective and coordinate response)

Mechanical Containment and Recovery Mechanical containment and recovery is the restriction of a spill / release movement through the use of booms or some other form of physical barriers and its subsequent removal using skimmers and other mechanical means. These operations may be required for large spills or spills / release which may impact environmentally sensitive areas. This response option would be used if the spill / release: • Threatens environmental sensitive areas, or • The spill is unlikely would be removed by natural processes.

The feasibility of a containment and recovery response is dependent upon having surface pollution that is capable of being contained and recovered and having suitable conditions for equipment deployment. The spill containment plan has been addressed in line with the recommendation of QRA analysis as prescribed in chapter 7.

Clean‐up

Oil or chemical spills may be allowed to collect or strand on a specific location in order to assist with clean‐up operations. Regardless of land type the spill impacts on, the method of clean‐up is usually labour intensive. Once a spill is controlled in terms of isolating the source, a response to a spill normally changes from an emergency to a project and needs would be managed as such. This may involve earthmoving equipment used to recover the absorbed spill and contaminated soil. Such operations usually involve the collection of significantly greater volumes of material than was originally spilt.

Waste Management

Solid waste due to clean up operation would be collected and treated and disposed in line with the prevalent Hazardous Waste Guidelines. 9.7 Noise Quality Management Plan The noise control plan would be applicable during the phases of construction of well sites, early production system, drilling operations and decommissioning/site closure of well sites. The noise control plan to ensure specific measures to minimize noise levels in the project site as 75 dB(A) per CPCB noise rules. The plan also outlines

10. Conclusion and Recommendation

Oil and Natural Gas Corporation Limited proposes to execute drilling operations in seven (7) Petroleum Mining Lease (PML) Blocks situated in the non-forest areas of Jorhat and Golaghat districts of Assam. ONGC tentatively have planned to generate 53 locations, covering a total area of 232.12 sq. km., spread over Borholla ML (10 locations), Mekerong ML (5 locations), Titabar ML (10 locations), Golaghat Extn IIA ML (7 locations), Golaghat Extn IIA (addl) ML (11 locations), East Lakhibari Extn. ML (5 locations), Kalyanpur ML (5 locations). The envisaged cumulative production in terms of O+OEG in next 15-16 years is in the tune of 1.76 MMt. The environment status of the PML areas and its surrounding have been assessed with respect to air, noise, soil, water, biological and socio-economic environment. The different project activities are identified and evaluated on the basis of primary and secondary data collection through field investigations, environment monitoring and from secondary sources viz. maps, reports, scientific literatures etc. In the pre drilling phase, different construction activities (land clearance, earth work, site grading etc.), movement of vehicles (for transportation of raw materials), operation of generators and other associated project activities will have impact on air, water, soil, flora, fauna and surrounding communities. On the other hand, during operation phase, operation of generators, gas compressors etc; flaring, discharge of wastewater and movement of vehicles will affect the air, noise, soil, ecology and social environment. With respect to occupational health, impacts are anticipated on the health of the employees during operation phase. Personnel working near the noise generating machines, DG sets, flare and hazardous waste storage area are more susceptible to health hazards. However, all these impacts can be overcome with the proposed mitigation measures proposed in Chapter 4 and Chapter 9. The overall impacts from the individual drilling sites is have been assessed to be of moderate to minor in nature when appropriate mitigation measures are would be implemented with proper planning and design. Adequate safety measures would be adopted along with suitable emergency response and disaster management plan to safeguard against all man-made and natural disasters. Environmental monitoring of ambient air quality, noise levels, surface & groundwater etc. would be carried out at regular intervals to monitor and prevent any deterioration of baseline environmental quality due to the proposed project. Overall; this project will bring economic benefits, increase energy security of the country and generate employment opportunities.

Sudin Pal Ecology Expert E Purpose of Consultation: • To study the socio-economic condition of the village • To study various sources of income in the area • To understand the state of infrastructure in the study area • To study the connectivity in the area • To understand gaps in development of the region F Key Points Inferred:

A consultation was conducted with the teachers and administrative staff of Borholla High School. The discussion was focused on the socio-economic condition of the village as well as the physical and social infrastructure. It was found out that majority of the population in engaged in agriculture. Predominantly paddy is cultivated, however vegetables are also grown throughout the year which are sold in local markets. Though Borholla is considerably a larger settlement than the surrounding hamlets, it was told that the scope for trade and business is very limited due to lack of the demand. The education facility is reported to be sufficient with 3 Lower primary schools, 1 middle school, 1 higher secondary school and 1 collage. However, the facilities provided at the schools were not adequate. Most of the houses were reported to have toilets but some still have temporary bamboo toilets. Most of these toilets including the school toilet do not have septic tank and blackwater from the toilets goes to open rainwater drains. The piped water supply is not adequate, and people rely on tube wells. The medical facility available is not sufficient and for any serious illness people go to Tatabari Hospital. The internal roads are broken and not maintained regularly.
