EXECUTIVE SUMMARY

1. INTRODUCTION

Reliance Industries Limited (RIL) has been awarded Coal Bed Methane (CBM) blocks in Sohagpur

East and Sohagpur West located in Shahdol District of Madhya Pradesh by the Government of India.

RIL is in advanced stage of setting up the required infrastructure for production and marketing of the

CBM gas from these allocated blocks. Commercial gas production from these blocks is likely to

commence by the second half of year 2014. The project proponent is Reliance Gas Pipelines Limited

(RGPL), a wholly owned subsidiary of RIL.

As part of this development, RGPL proposes to build and operate 312 km, 18” diameter cross-country

pipeline for monetization of CBM reserves. The pipeline will be laid from Shahdol in MP and hooked

up with GAIL’s existing HVJ Pipeline at Phulpur in Uttar Pradesh. This will enable the distribution of

CBM gas to the customers along the pipeline route and on HVJ pipeline network.

The pipeline route crosses Songhariyal Sanctuary, an “Eco- sensitive Zone” as per the guidelines of

MoEF (Wildlife Division) and hence requires Environmental Clearance. RGPL has engaged Hubert

Enviro Care Systems (P) Ltd., Chennai for carrying out Environment Impact Assessment (EIA) Report

for the project.

RGPL have submitted the application for Environmental Clearance (EC) to the Ministry of Environment

and Forests (MoEF) on 5th December 2012. After the presentation to the Expert Appraisal Committee

(EAC) on 5th March, 2013, MoEF issued Terms of Reference (TOR) for the project on 30

th April, 2013.

This EIA report has been prepared by Hubert Enviro Care Systems (P) Ltd.in compliance with TOR

requirements and as per guidelines of the MOEF EIA Notification of 2006.

The EIA report includes description of the baseline environment, anticipated environmental impacts

with the mitigation measures, an analysis of alternatives, the proposed environmental monitoring

program, risk assessment along with the disaster management plan, project benefits, environmental

management plan and summary of the EIA study.

2. PROJECT DESCRIPTION

Proposed pipeline of 312 km traverses through 235 km in Madhya Pradesh (133 km in Shahdol, 23

km in Sidhi and 79 km in Rewa) and 77 km through Uttar Pradesh (all of which fall in Allahabad

district). The proposed route minimizes overall traverse through forest land and keeps sufficiently

away from eco-sensitive areas in its vicinity namely Sanjay Dubri Sanctuary, Bandhavgarh National

Park and Panpathar Wild Life Sanctuary. Due to Songhariyal Sanctuary’s East-West linear placement,

the pipeline route crosses the sanctuary for an approximate length of 0.9 km across Son River. The

route encounters about 124 km of rocky terrain, a commutative forest land of approximately 29.70 km

length, 3 no. major river crossings namely Ganga, Son and Belan, which will be executed by

Horizontal Direction Drilling (HDD) method. The pipeline also crosses 6 national highways, 6 state

highways and 3 railway crossings. It passes through Gurh hill and Dakrabari hill for a cumulative

length of 3 km. The pipeline traverses through a total of 246 villages in the 4 districts of the two states.

The pipeline route map has been shown in Figure ES 1.



Figure ES 1 Pipeline Route Map



The pipeline shall be designed to transport CBM gas up to 6 million metric standard cubic meters per

day (MMSCMD). The proposed pipeline will be 18” dia, 312 km and having one compressor station

(CS) at Shahdol (point of origin). Mainline valves (MLV) will be installed at an average distance of 30

km along the pipeline as per the code requirements depending upon population density. As per

preliminary assessment, there will be a total of 12 MLVs out of which 6 will be remotely operated from

pipeline operations centre and balance 6 will be locally operated valves. One intermediate

compressor station will also be installed enroute the pipeline. Metering and regulating (M&R) station

will be installed at hookup point with HVJ pipeline at Phulpur. The pipeline configuration and facility

locations will be determined and firmed up based on detail engineering of the project.

The pipeline system shall also comprise of cathodic protection system, supervisory control and data

acquisition (SCADA) system, dedicated optical fibre cable (OFC) based telecommunication system,

leak detection system / pipeline application software, emergency shutdown system, flow

measurement and control instrumentation, fire and gas detection system, fire protection system,

control room, auxiliary buildings and associated facilities. Utilities required for the compressor stations

and for other pipeline facilities like MLVs and M&R station etc. will be suitably provided, for day to day

smooth functioning of the respective facilities. The proposed pipeline is for the purposes of CBM gas

transportation and there is no manufacturing involved. Hence there is no requirement of any raw

materials and its related recycling and re usage.

Figure ES 2 Schematic Diagram of Proposed Pipeline



Land Requirement

To facilitate construction and maintenance of the pipeline, 20 m wide Right of Use (RoU) in land will be

acquired as per the provisions of the Petroleum and Mineral Pipelines (Acquisition of Right of User in

Land) Act, 1962. The pipeline RoU will cover an area of ~561 Ha. The land under RoU will be restored to

near original condition after construction of the pipeline. Based on field survey about 29.70 km of the RoU

is expected to be through Forest Land. Permission for diversion of forest land for pipeline usage shall

comply with the provisions of the Forest (Conservation) Act, 1980 and the Forest (Conservation) Rules,

2003. Separate approvals from concerned authorities will be obtained for laying the pipeline within

government land. Permission will also be obtained from various authorities having jurisdiction for the

purpose of crossing of existing pipelines. A total of about 34 Ha of land will be required for setting up of

facilities such as compressor stations, mainline valve stations and metering and regulating station. All

applicable requirements for such usage shall be complied with.

Water Requirement

Total tentative water requirement during operation phase, which will include domestic, make-up water

(fire water) and green belt development, is estimated to be approximately 240 KLD total for two

compressor stations. Water required for MLVs and M&R during operation phase is estimated to be

approximately 7KLD total, which will be primarily met by providing tube well at respective location. There

will be a one-time requirement of 4,800 m3 of water per section of hydrostatic testing (~ 30 km). This

water will be reused in different test sections to an extent practically feasible.

Manpower Resources

It is estimated that about 2,000 people, including labour, will be deployed as peak work force during

construction. Local manpower resources will be employed during construction phase to the extent they

are found technically suitable. The pipeline operation being highly automated from safety considerations,

the maximum deployment of skilled persons is expected to be of the order of 50. Outsourced work force

for routine maintenance shall be of the order of 85. The total headcount will be spread across various

facilities located along the pipeline route such as CSs, MLVs and M&R.

Material and Machineries

The major construction material required will be pipes and pipe fittings, welding materials and equipment

required for welding, ready mix concrete etc. Different equipment, machinery like cranes, backhoe, truck-

trailers, bulldozers, excavators, dumpers, pumps, DG sets etc. would also be required. During the pipe

installation process across major perennial rivers HDD or an equivalent technique will be used that would

cause minimal interference and / or contamination of the water body. Gas Engine Generators (GEG) shall

be installed at the compressor stations to meet its captive (continuous) power requirement.

Waste management

As the pipeline will be laid underground, excavated soil will be reused for back filling. Top soil will be

reinstated on top layer as original. The primary source of solid wastes will be from construction camps.

During construction, the solid waste generated will be mainly packaging and wrapping material, stubs of

spent welding electrodes, used rags and house-keeping waste from the construction camps. Site

contractors will be responsible for disposal/resale of these wastes, in an environmentally friendly and

acceptable manner. Only domestic type solid waste like paper and cardboard waste may be generated at

the compressor station during operation phase. These will be sorted, sold for recycling or reused as



possible. Canteen / food waste will be suitably managed. Liquid wastes will primarily consist of sewage

pertaining to domestic sanitation wastes from construction camps and at compressor station. The effluent

will be discharged in the local sewer or in soak pit/septic tank in consultation with concerned State

Pollution Control Board (SPCB).

Statutory Approvals

RGPL will obtain statutory clearances and approvals from the authorities having jurisdiction. RGPL will

also obtain Consent for Establishment under Air (Prevention and Control of Pollution) Act, 1981 and

Water (Prevention and Control of pollution) Act, 1974 from the concerned SPCB. Environment Clearance

will be obtained in accordance with Environmental Impact Assessment Notification, 2006 from MoEF.

Since the proposed pipeline traverses for approx. 29.70 km length through the reserve forest area,

permission will be obtained as per Forest (Conservation) Act, 1980. To minimize impact on the forest

area, only a restricted corridor of 15 meter width shall be utilized. Permission under the provision of Wild

Life (Protection) Act, 1972 for laying the pipeline through a 15-m wide strip of 900 m length corridor

across Songhariyal sanctuary shall be obtained from the Wildlife Department. The permissions, as

applicable, from relevant authorities viz. road, rail, water body, foreign pipelines/utilities crossings, CCOE,

Factory Inspector, Electrical Inspector, Fire Safety Inspector etc.will be obtained by RGPL.Separate

approval will be obtained for RoU under Government land. Compensation disbursement after declaration

of RoU acquisition in the Gazette will be undertaken prior to construction activity.

3. DESCRIPTION OF ENVIRONMENT

The data for all environmental components is collected from primary site investigation as well as from

secondary sources. The understanding towards baseline environmental conditions helps in identifying the

possible impact of the project on the environment. Furthermore, the primary data has also been analyzed

from environmental monitoring surveys conducted at selected locations. The baseline data collection was

carried out from the 1st week of March 2013 to 1

st week of June, 2013. Various environmental attributes

that have been considered for formulating the baseline environmental conditions are given under Table

ES 2. The monitoring locations in and around the project route are shown in Table ES 3.

Micrometeorology

A temporary, field meteorological station was established on the roof of Reliance office at Rewa town.

Monitoring of meteorological parameters comprising air temperature, relative humidity, wind speed, wind

direction and rainfall were carried out. The project area during most part of the study period, remained dry

with a dusty wind with speed upto a maximum of 52 km/hr, primarily from West Direction. The relative

humidity remained less than 50% throughout, with the temperature ranging from 12 to 43 0C.

Air Quality

A methodically designed Ambient Air Quality Monitoring (AAQM) network covering 10 sampling locations

was designed. To establish the baseline monitoring status of air environment in the study area during pre-

monsoon season (1st week of March – 1

st week of June, 2013), air quality was monitored as per CPCB

guidelines (twice a week sampling and 24 hr continuous sampling each day). The sampling was done as

per IS standards. A onetime VOC sampling for THC, MHC, NMHC was done in the study season. The

ambient air quality observed along the pipeline route was mostly found to be below the prescribed

standards of CPCB. Relatively higher PM10 values were observed, that can be accounted to the proximity

of the monitoring stations to the roads and to the dusty summer winds in the region



Noise Levels

Ambient noise level measurement monitoring was carried out at 10 locations along the pipeline route.

Noise monitoring was done twice a week in the 10 monitoring locations. The noise levels observed along

the pipeline route were mostly observed to be below the prescribed standards of CPCB. Kaithwal was

found to have higher than prescribed limits due to its presence on the busy state highway.

Water Quality

The baseline water monitoring for water quality has been carried out from 10 ground water sources and 4

surface water sources. Water sampling and analysis were done as per CPCB guidelines and IS

Standards. Ground water samples were collected within 1 km distance from the pipeline route along the

312 km stretch. All the samples were collected from residential areas from the areas adjacent to the 10

air monitoring stations. The water samples from Gudhawa, Patahara and Chak Abdul Karim were

collected from open wells and the rest all sources are from hand pumps. The water samples results for

the collected ground water shows that most of the water samples collected adhered to CPCB and IS

permissible limits for drinking water sources. But sample from Semra was found to have higher Iron

content and those Patahara, Gudhwa and Chak Abdul Karim showed higher turbidity. This turbidity can

be accounted for the fact that these were collected from open wells.Surface water samples were collected

from four locations, which are Ganga River (Near Gharaghanpur), Son River (Near Budwa), Belan River

(Near Kaithwal) and Son Gharial Sanctuary (Near Hatha). The water samples results for the collected

surface water shows that most of the water samples collected adhered to CPCB and IS permissible limits

for drinking water sources. But sample from Ganga near Gharaghanpur was found to have higher Iron

content, Alkaline Ph and high turbidity. This might be due to the influence of effluents and sewages being

let down into the river from nearby Allahabad City.

Land Environment

The proposed pipeline is found to pass through a minimum elevation of 70 m above mean sea level (msl)

at Ganga River, a maximum elevation of 482 m above msl in Shahdol area. The average elevation comes

out to about 290 m above msl. The project is located on Seismic zones II and III, and thus not prone to

earth quakes. The present land use pattern of the study area (i.e. 10 km radius of the pipeline route) has

been assessed based on NRSA published IRS LISS III (1:50,000) data and validated from on field visit

and data collection. The land use analysis show that the area is of predominantly agriculture land (61%)

followed by forest (23%) and barren wastelands (11 %) in the study area.

Soil Quality

To assess the existing soil characteristics, samples were collected from different locations in the study

area. Ten soil samples were collected within 1 km of the pipeline route. The soil in most of the 10

sampled locations was found to be fertile and rich in mineral contents. The major soil type along the route

was found to be silty clay soil covering about 30% of the area.

Biodiversity

The entire stretch covering Madhya Pradesh is inherently rich in biodiversity explaining the presence of

some significant sanctuaries and national parks in and around the area. While the proposed pipeline

route does not cover any reserved forest areas of Uttar Pradesh, it study area includes Son Gharial

sanctuary along with several reserve forest areas. These forests are rich in flora fauna species many of

which are endemic to the region. But the route has been so selected that it falls out of any core area and

most forest areas where the route passes through have been converted into agriculture land by locals.



Socio-Economics

The pipeline passes through Shahdol, Sidhi and Rewa districts of Madhya Pradesh and Allahabad district

of Uttar Pradesh. The socioeconomic status of the route was assessed through primary field survey and

through secondary data collected from the census and other government sources. The socio-economics

of the area was assessed for the employment, education, healthcare and other factors that affect the

quality of life in the region.

4. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITAGATION MEASURES

The environmental impact of a project depends both on the proposed project activities and the existing

environmental settings. The ground level concentrations expected after commissioning of the

compressors were modelled out to be around 34.351 g/m3 of NOx and 158.971 of PM10 for compressor

station 1, and 36.551g/m3 of NOx and 149.371of PM10 for compressor station 2. It was observed that

the NOx and PM10 emission values for the compressor stations are below the CPCB standards. Over all

PM10 values since are higher in the areas, the same is accounted for the overall higher GLC values for

PM10. The resultant noise levels for the operating phase for the compressor stations are modeled to be

between 33 dB (A) to 40 dB (A) at the plant boundary, under normal operations. Thus the noise levels

from the compressor stations taking into account baseline noise levels will be as per CPCB standards.

The identified impacting activities and proposed mitigation measures are given in Table ES 4. The

5. ANALYSIS OF ALTERNATIVES (TECHNOLOGY AND SITE)

Route engineering through a desktop study was undertaken for assessment of possible alternate routes

to finalize optimal pipeline route. Total of 3 possible pipeline routes were identified namely Option -1 (312

km), Option - 2 (300 km) and Option - 3 (315 km).

Possibility of avoiding Forest Land

In selection of the route, all route options have been examined in detail to ascertain the possibility of

avoiding the forest land. It may be noted that the Sohagpur East & West Coal Bed Methane Blocks from

where the pipeline is originating, itself is located within Ghorbe and Mamora Reserved Forest and any

pipeline exiting from this block will have to pass through these RF. In addition, the location of the CBM

Blocks is such that it is surrounded by Panpatha Wildlife Sanctuary and Sanjay Dubari Sanctuary in the

North, Bandavgarh National Part in the Northwest, Guru Ghasidas National Park in the northeast and

Achanakmar Wildlife Sanctuary in the South. In the north, Songhariyal Sanctuary is also present which is

linear and stretches linearly along the border of Rewa and Sidhi district. In addition, there are numerous

reserved forests spread out all around these areas. Maximum care has been taken in the route selection

process to avoid forest areas to the most extent.

Selected Option

Pipeline route Option-1 has been selected for the project after thorough review, analysis and comparison

with alternate routes on following counts and merits:

i. It crosses least of the reserved and protected forest area.

ii. It minimizes traverse through sanctuary.

iii. It crosses minimum number of major rivers.

iv. It has least construction difficulties, faster execution and thereby minimizing the impact during

construction.

v. It completely avoids the buffer zones of major sanctuaries and national parks in the area.

Due to the presence of National Parks, Wildlife Sanctuary, RF all around the CBM blocks, a pipeline route

avoiding the forest land is totally not feasible.

6. ENVIRONMENTAL MONITORING PROGRAM

The monitoring plans for environmental quality assessment during the different phases of the project are

given in Table ES.6. There would be an Environment Monitoring and Management Cell headed by a

7. QUANTATIVE RISK ASSESSMENT

Quantitative Risk Assessment (QRA) study was undertaken for the proposed 18” diameter cross country

underground pipeline for the transfer of natural gas. The pipeline originates at Coal Bed Methane (CBM)

blocks located in Shahdol District in Madhya Pradesh and connects at GAIL’s existing HVJ Pipeline at

Phulpur in Uttar Pradesh.

The aim of QRA study was to identify potential hazards, assess the consequences and frequency of

hazards and evaluate the risk to personnel, property and public. To assess the relative level of risk posed

by the proposed project, a comparison was made with risk criteria that is considered tolerable (ALARP)

for similar operations

The overall approach and methodology employed for the study was based on the guidelines given in IS

15656 : 2006, Indian Standard – Hazard Identification and Risk Analysis – Code of Practice, May 2006,

using PHAST Software/Correlations.



The pipeline system will be provided with state of the art safety systems like cathodic protection system,

SCADA, leak detection system / pipeline application software, Fire and gas detection systems, etc.

The proposed transfer of natural gas was examined for inherent hazards or the potential to result in an

unplanned event or sequence of events at different sections along the pipeline route. Several hazards

that can cause failure of pipelines were identified. These included loss of integrity/ damage due to

interference from third parties, corrosion, accidents, human error, sabotage, etc., during normal operation.

Analysis of past accidents was used to establish the credibility of accident scenarios.

Consequence Analysis

A number of releases of natural gas capable of resulting in fire and/ or overpressure effects along the

pipeline were simulated and quantified using consequence models as per international guidelines. The

pipeline has been assessed for potential for leaks and rupture at various sections. The effects were

simulated and analyzed at Compressor Station 1 and 2, M & R station and between two MLVs as

representative of the pipeline route.

The main observations from the consequence assessment are given below:

A total of thirty scenarios were envisaged at different sections along the pipeline route. Of these

scenarios, the failure cases considering 100 mm dia hole and 20% Cross Sectional Area of pipe

were found to be most significant.

The potential outcomes from the scenarios include jet fire, flash fire and vapour cloud explosion

(VCE). The effects were given in terms of thermal radiation and overpressure levels.

The effect distance of jet fire corresponding to 4 kw/m2, 12.5 kw/m

2 and 37.5 kw/m

2 radiation was

recorded maximum upto 116 m, 107 m and 99.5 m respectively..

Probability Analysis

Probabilistic assessment was carried out using event-tree analysis (ETA) approach for each

consequence scenarios identified. Factors considered in ETA include leak/ rupture frequencies of the

initiating event, failure of protective/ warning devices, instruments, human action, presence of ignition

sources and mitigation system.

Estimation was carried out for two basic types of initiating events viz., leak or rupture of pipeline at

compressor/ M&R Stations and leak/ rupture of pipeline along the pipeline route

Failure data of pipes and failure of instruments and interlocks collated from published industrial data

bases was used to generate the probabilities at each location.

For all considered modes of release, the major consequence is jet fire followed by flash fires and VCEs.

While the probability of jet fire and flash fires are in the range of 10-5

to 10-6

per year, for VCE it is in the

range of 10-7

to 10-8

per year.

Individual Risk (IR) along Pipeline route

The risk of the proposed transfer operations to personnel inside the compressor stations and along the

pipeline route was evaluated. The entire pipeline route was surveyed to locate the areas of habitation/

settlements within the proximity of the pipeline. Over 70 locations with significant number of dwellings

were identified.



Risk evaluation carried out using Individual Risk (IR) approach. Individual risk was obtained from the

pipeline failure probability calculated based on historical data.

The individual risk to personnel was evaluated for three zones along the pipeline route where people are

expected viz., 0-20m, 20-125m and beyond 125m, based on distance measured perpendicular from the

pipeline. Individual Risk was estimated summing up the potential effects of all events along the pipeline

for the three zones and compared with the acceptance criteria (ALARP-As Low As Reasonably

Practicable) adopted for the project

The findings are reported below.

i. For the area >125 m perpendicular to the pipeline, the risk is of the order of 10-6

per year, which

falls in the Negligible Risk region.

ii. For the area between 0 to 20 and 20 to 125 m perpendicular to the pipeline the risk falls in the

range of 10-5

per year, which can be considered as the ALARP region

iii. IR at manned locations ranges between 10-5

to 10-6

per year and falls within the ALARP region. It

is assumed that the workers will be protected with the safety protective system and provided

adequate training.

Societal risk was evaluated along the pipeline route and was found to be in ALARP region.

Findings & Recommendations

The risk from the proposed natural gas transmission pipeline falls within acceptable limits as per the risk

criteria adopted. RGPL to focus on long-term safety measures, impact reduction and leak preventive

strategies, some such measures are mentioned below:

i. Leak Reduction: The risk levels at the compressor station though at ‘Acceptable’ levels, can be reduced further if the number of flanges, valves, interconnections, etc., on the pipe sections is kept to the minimum, thereby reducing the number of leak points.

ii. Protection at manned locations: Within the compressor & metering stations, manned buildings

should be located at appropriate distances to ensure minimum damage in the event of fire or explosion

iii. Protection against ignition: Potential sources of ignition (mobile or fixed) within the flammable

zones are sufficiently eliminated or protected to prevent ignition of flammable gas cloud

iv. Protection against high thermal radiation: The following measures may be considered for

protection from high thermal radiation due to jet fires at the compressor stations.

a) All critical isolation valves (ESD) within the high radiation zones, should be fire-safe.

b) Automated valves/ ESD should be designed for fail safe position in the event of failures of

utilities during emergencies

c) Water sprinklers for mitigation of effects of jet fires should be installed at all critical areas

d) As part of emergency response, remote operated valves should be installed at suitable

intervals to shut off the supply of gas in event of leak.

v. Security & Surveillance: Ground patrolling/survey of the pipeline route should be carried out by

operators with knowledge of local area.



vi. Compressor Station Layout: Sufficient open space and ventilation should be provided at the compressor station to promote quick dispersal of gas leaks.

vii. Pipe thickness data acquisition and analysis: Monitoring of pipe wall thickness data, recording

and follow up will enhance the long term safety of the pipeline. .

viii. Location of building inside the station: Within the compressor and metering stations, a minimum

proximity distance between pipelines and buildings should be maintained to minimize heat radiation effects on buildings and structures

ix. Provision of HSEMS: Long term safe management of cross-country pipelines requires an

effective Health, Safety & Environment Management System (HSEMS) in place.

x. Emergency Management: The worst case scenarios from the risk evaluation should be

considered as the basis for emergency management.

xi. Safety Reports: Safety audits should be conducted and the reports updated at regular intervals.

8. DISASTER MANAGEMENT PLAN

Disaster management plan (DMP) was prepared for the proposed transfer of natural gas from Shahdol in

MP through a proposed 312 km SHPPL cross-country natural gas pipeline project to the tie-in with the

GAIL HVJ Pipeline at Phulpur in UP. The plan was prepared in compliance with the PNGRB regulations.

The plan describes the emergency situation, the organization and line of command, the system and

equipment to be used and duties of the key personnel. Site specific plans prepared based on the risk

analysis undertaken for the proposed operations, which identifies the potential worst-case scenarios that

can develop into an emergency. The plan considered both proposed preventive and mitigation measures.

The plan comprises of two phases, namely proposed preventive measures followed by the emergency

response plan to be deployed should an emergency occur.

Classification of Emergencies

Emergencies at SHPPL have been classified into three different levels based on seriousness and

response required. These levels are

Level 1:. This is an emergency which can be effectively and safely managed and contained within the

site/location with the help of available resources/ equipment and has no impact outside the

compressor station/ site.

Level 2: This is an emergency which cannot be effectively and safely managed and contained within

the site/location with the help of available resources/ equipment and additional support is required

and is having effect beyond the compressor station has no impact outside the compressor station/

site and where external support of mutual aid member or local fire service is required to control the

emergency.

Level 3: This is an emergency with off-site impact which could be catastrophic and is likely to affect

the surrounding public, environment and property outside the compressor station/ facilities. E.g.

Bush/forest fires,

Floods



Earthquake

Sabotage

Act of War

This is to ensure that appropriate emergency response procedures can be effectively implemented by the

emergency response team (ERT) as individual emergency situations call for mobilization of different

resources or emergency actions.

The criteria for classification of various levels of emergencies and associated response along with a

pictorial depiction of the 'decision tree' will be displayed prominently to enable emergency classification.

Classification is based on factors such as type of injury or damage, material loss, requirement of external

assistance for effecting control, impacts of environment and reputation of the company, etc.

The main elements of the plan are summarized as follows:

A. Management Measures for Prevention of Emergencies

The pipeline project will be adopting and implementing risk mitigation measures during both pipeline

construction and operations stage in accordance with relevant PNGRB guidelines and OISD standards to

effectively address any potential emergency situations that may arise as result of release and ignition of

natural gas from pipeline leak or ruptures.

The key aspects of these measures are:

i. Pipeline Design & Material Selection: Design and Material Selection of the proposed natural

gas pipeline has been undertaken in accordance with the provisions of ASME B31.8 and PNGRB

T4S.

ii. Pipeline Safety Devices & Features include an emergency shutdown system to close down all

gas delivery system and to de-energize the electrical facilities, over pressure shut off valves with

alarm, etc. The pipeline will be monitored and controlled from SCADA system and leak detection

software to ensure effective and reliable control, management and supervision of the pipeline. All

remote MLV stations, dispatch & receiving stations will have suitable field signals’ connectivity

with SCADA.

iii. Pipeline Corrosion Control will be provided by a combination of anticorrosion coating and

cathodic protection.

iv. Pipeline Operation & Maintenance: A detailed operation and maintenance procedure for control

system and safety interlocks will be developed for normal operations & shut down/maintenance,

temporary operations, emergency shutdown details and emergency operations. A detailed

periodic preventive maintenance procedure and schedule will be developed for entire pipeline

system considering the recommendations given by the original equipment manufacturer and in

accordance with PNGRB T4S & OISD standards.

v. Fire Protection System & Emergency Response The natural gas pipeline will have fire and

gas detection system equipped with audio visual alarm and gas monitoring system located close

to the potential source of leakage. Appropriate communication system like telephone, walkie-

talkie sets, optical fibre cable based communication system will be provided. A mutual aid

scheme for the fire fighting and emergency rescue operation will be developed involving local

industries, local govt. agencies. Emergency mock drill involving all mutual partners will be

conducted at least once in six months.



B. Emergency Response Plan

Emergency response plan will be developed with the resources available within the company. The

important stages of the response plan are declaration of an emergency, identification of resources &

manpower, ending of an emergency and rehearsal of the plan. Declaration of an emergency would

involve recognizing a leak and reporting to Station in charge of nearest compressor station.

Other features are summarized below:

i. Emergency Response Structure: An emergency response structure will be developed for

effective response to the emergency. The structure defines the main functions of the decision

makers and the individual roles as well. A basic organogram is given in the detailed report.

ii. Roles & Responsibilities of Team: Emergency response team (ERT) to respond to fire,

accidents and technical emergencies will be constituted from operations personnel, who can be

called upon 24 hours a day, supported by senior management field personnel as and when

required. The ERT will receive specific training for their roles and exercised on a regular basis.

The proposed functions of employees that are planned to be deployed will be finalized prior to

commissioning

iii. Operations Control: The pipeline operation will be monitored and controlled through Local

control system and POC in command which will have the provision for emergency shut down or

isolation of Pipeline. Security: Surveillance of the entire pipeline will be held periodically through

ground patrolling. Using operators with knowledge of local area will be deployed for ground

patrolling of the pipeline route.

iv. Medical and First Aid: All arrangements will be made available at SHPPL site offices and camps

for medical and first-aid. First–Aid facility will be provided at compressor stations, master pipeline

operation center/ local control center, MLVs and M&Rs. Adequate first-aid training will be

provided to employees at these locations.

v. Communication: Responsibility for external and internal communication will be assigned at each

station. Dedicated fiber optic cable based communication system will be provided for quick

communication between the control stations, dispatch and delivery station(s) of the pipeline. The

backup system will consist of appropriate combination of fixed telephone lines/data-bandwidth of

the local service provider, mobile phones, VHF sets etc.

vi. Emergency control room: A safe location will be designated as emergency control room (ECR)

within the compressor stations.

vii. Emergency Procedures: SHPPL will evolve easy-to-follow procedures for responding to the

identified situation. The plan will be rehearsed once in three months.

Ending of an emergency: After controlling an emergency, the site ERT Leader will declare as “All Clear”.

The siren will be sounded for 2 minutes to indicate that the Emergency is over.

The basic elements for an effective plan have been included in the development. Prior to the

commissioning of the project, copies of the plan are to be given to the authorities.

9. PROJECT BENEFITS

With implementation of gas pipeline project, entire region along/nearby the pipeline route shall have

access to gas source and ensure uninterrupted supply of energy and thereby help in overall economic

development of these regions. In addition, the following benefits are also envisaged:



The pipeline, during construction and operation phase will generate direct and in-direct

employment as there shall be requirement of unskilled and skilled workers in site activities, supply

of raw material, auxiliary and ancillary works, which would improve the economic status of the

people in area.

The project would help in increasing skills levels of personnel through exposure to site activities

and state of the art technology and corporate social responsibility (CSR) activities taken up by

Reliance.

The benefits of reduction in energy consumption due to pipeline mode of transportation of gas

and reduced transportation losses will get passed to End users and Industries. The pipeline will

transport natural gas which is the cleanest burning fossil fuel and considered an environmental

friendly fuel. The natural gas burns completely and doesn’t leave behind any unpleasant soot,

ash or odors as is the case with other fuels.

Natural gas is non-toxic if inhaled in small amounts. Natural gas is not poisonous or harmful to

humans. It is lighter than air hence in event of leakage it gets dispersed easily. Further it is also

not explosive, if mixture of gas in the air is less than 4 - 5% or more than 15%.

Oil used as fuel need to be stored in tanks and hence is a major source of fire, On the other hand

natural gas can be fed directly to customers through pipelines and thus risk of fire due to storage

is significantly reduced.

Pipeline mode is the safest and reliable mode of transportation. Transit losses are the lowest in

pipeline transportation. Vagaries of nature like floods, storm etc. do not disturb pipeline

operations system. Pipeline being underground, provide no direct contact with the general public

there by reducing its hazardous impact as well as providing better overall security. The pipeline

system can't be easily damaged by weather or affected by weather conditions. The pipeline

connectivity also improves the availability of the highway / railways for transporting other

materials / goods as it helps in eliminating the movement of tankers resulting in de-congestion of

roads and reducing noise and air pollution.

Switching over to natural gas from oil also eliminates the need for an underground storage tank,

thereby eliminating the threat of oil spills, soil contamination and costly environmental clean-up. In

case of above ground storage tank, switching to natural gas eliminates worries about spills or

corrosion of the tank. The implementation of project will help in replacement of furnace oil and

other liquid fuel with Natural Gas and will help in reducing pollution in the regions along pipeline

route.

Supply of additional un-interrupted gas will enhance the power generation capacity in the region

which is expected in-turn to accelerate the economic growth in the region.

Development of industries and power plants will generate direct and in-direct employment in the

area.

Pipeline will be able to feed natural gas to multiple industrial units and thereby helping them in

switching over to cleaner fossil fuel.

Connectivity to city gas network to pipeline from delivery point will reduce the requirement of LPG

cylinders used in households.

10. ENVIRONMENTAL MANAGEMENT PLAN

The Environmental Management Plan (EMP) includes both generic good practice measures and site

specific measures, the implementation of which is aimed at mitigating potential adverse impacts

associated with the proposed activities. EMP describes the measures for minimizing impacts that are



likely to arise during different phases of the project such as pre-construction, construction and operation.

11. SUMMARY AND CONCLUSIONS

Impact due to Pipeline Route Selection

The proposed pipeline route has been so selected out of various options, primarily due to:

Shortest length of the pipeline between source and destination points

Minimum impact to reserved forests and other sensitive areas

Minimum number of major water crossings

Minimum impact to the environment

Avoidance of populated areas/ industrial area

Easy access to the route during construction, operation and maintenance of the pipeline.

Impacts during construction of the Pipeline

Earth work excavation, transport of construction materials, handling, laying and jointing of

pipelines - These activities would cause a general increase in levels of dust and suspended

particulate matter in the ambient air. However, this increase in concentration would be of

temporary nature and localized.

Movement of vehicles for transportation of construction material and diesel generators – These

activities would cause a marginal increase in the levels of oxides of nitrogen, carbon monoxide

and hydrocarbons.

Impact from sediments being washed into the water bodies while the pipeline is laid across them.

The pipeline will not be laid in rainy season, which will avoid adverse impacts on water body.



Drinking water for base camps will be made available through local supply system. The domestic

sewage from the construction camps will be either disposed off into the local sewage system and

if required, will be treated in soak-pits and septic tanks.

Water consumption during hydro-testing of pipeline - Efficient use of water will be made to reuse

test water in different test sections. Water will be tapped from different sources along the pipeline

route, without unduly disturbing its normal users.

At major crossings, Horizontal Directional Drilling (HDD) method will be deployed and will in no

way disturb the natural water flow or cause any pollution to the water body. Hence there will not

be any obstruction/damage to fishing, recreational and navigation activities. The pipeline will be

laid at a minimum depth of 2.5 meter below the scour depth. .

The pipeline will be buried all along its length hence impact on land use pattern will be marginal

and reversible.

Some quantity of earth excavated for pipeline laying will become surplus after installation of the

pipeline and may be required for disposal. However as this excess of earth will be taken to low

lying area for filling purpose, the aesthetics of the pipeline RoU and soil quality will not be

affected.

Possible impacts on the land environment could be due to spent drilling mud (bentonite slurry).

The spent drilling mud will be disposed off as per applicable norms in consultation with

local/regulatory authorities. RGPL will ensure that spent mud material should not be

contaminated before final disposal.

Noise Generation - The major human settlements are at a distance from the pipeline route where

the noise levels due to construction activities are estimated to be around 70-90 dB(A). Such

onetime exposure is not expected to last for more than few weeks and shall not exceed the

stipulated standards.

Selection of the pipeline route has been done in such a way that eco-sensitive areas which may

be affected during the construction of the pipeline are minimised.

Impacts during operation of the Pipeline

No air emissions will be generated during the operation phase except at Compressor stations.

Adequate stack height will be provided for Gas Engines for compressors, Gas Engine Generators

(GEG) and DG sets provided at Compressor stations. Also scrubber will be provided at

compressor station sites to filter particles of size greater than 5 -10 µ. Thus the impact on air

environment during the operation phase will be minimal.

The compressor stations enroute will be kept in a built-in-area that will reduce the noise level to

minimum. The exhaust will be affixed with mufflers to reduce the noise level from the DG sets and

compressors on site. Further, Gas Engines, compressors, Gas Engine Generators and DG Sets

will be provided with proper enclosures. The incremental noise level in the nearest village due to

the proposed operations will be minimal.

There will be no significant impact on ecological environment during the operational phase of the

project.

Natural Gas is a non-toxic gas and the main hazard is asphyxiation due to reduced oxygen levels.

The probability of leakage will be significantly reduced by adoption of appropriate safety

measures.

The probability of leak from a pipeline is remote. Pipeline will be buried minimum 1 m in the

cross-country section and 2.5 meter below the bed level at major crossing.



Post Monitoring Program

The implementation of mitigation measures during construction and operation phases will be

monitored. The monitoring plan would provide for periodic revision, if necessary in light of the

baseline status to indicate progress in project implementation and changing environmental

conditions so as to provide a basis for evaluation of project impacts. The post monitoring program

would include the following:

Approved means of leak detection would be employed as per the provisions of PNGRB T4S.

Regular and adequate surveillance of pipeline particularly at crossing locations and settlements.

Monitoring of pressure, coating conditions and cathodic protection

Conclusion

There will be a beneficial effect from pipeline project that will directly and indirectly boost the living

standards of the people, save foreign exchange and with increase in industrial activities, create

more jobs in the local economy. Thus, it can be concluded on a positive note that after the

implementation of the mitigation measures and EMP, the proposed activities of RGPL will have

negligible impact on environment and will beneficial for the local population.
