Laying of Anjar - Chotila Natural Gas transportation pipeline project with associated facilities from Anjar (Dist. Kutch) to Chotila (Dist. Surendranagar), Gujarat by M/s Gujarat State Petronet Limited
Executive Summary

EXECUTIVE SUMMARY
INTRODUCTION
As a fuel, natural gas competes with a range of alternative products such as coal and lignite as well
as petroleum products such as liquefied petroleum gas, naphtha, high speed diesel, light diesel oil
and fuel oil. However, due to lower fuel operating costs and better combustion characteristics, natural
gas has distinct economic advantages over other sources of energy. In addition, natural gas has
substantial environmental advantages over other energy sources, due to lower emissions.
The development of proposed project is for natural gas transportation within state of Gujarat. The
proposed project is planned to be developed by M/s Gujarat State Petronet Limited (GSPL) India.
M/s GSPL, a Group company of GSPC is one of the leading company in the field of Natural Gas
transmission line. It is in the process of establishing & expanding its pipeline network all over the
Gujarat State to take care of future demand-supply gap of natural gas to fulfill the requirements of
various consumers throughout Gujarat. It is first company in India to transport natural gas on open
access basis and is a Pure Natural Gas Transmission Company.
GSPL is a pioneer in developing energy transportation infrastructure and connecting natural gas
supply basins and LNG terminals to growing markets. The company has developed requisite
expertise and confidence with proven project management competencies.
GSPL proposes to lay a pipeline for the supply of Natural Gas from Anjar to Chotila. The proposed
Anjar to Chotila Pipeline will originate from village Ratanpar-(GSPL's ARPL SV-8 TOP- 8), Taluka-
Sayla & district Surendranagar of Gujarat State . Pipeline stretch will cover a distance of 196.14 km,
and runs through Surendranagar, Morbi & Kutch regions and terminates at GSPL's Dispatch station
at village Rata Talav, Taluk Anjar & district Kutch of Gujarat State.
M/s. Gujarat State Petronet Limited (GSPL) has received the Authorization from PNGRB (Petroleum
and natural Gas regulatory Board) for the transportation of natural gas with a permissible RoU width
along the pipeline route.
PROJECT DESCRIPTION
The proposed underground Natural Gas Pipeline project is of approx. 196.14 KM stretch from Anjar
to Chotila with associated facilities such as Sectionalized valve Stations /Tap-off/Metering
/Receiving/ Dispatch/Intermediate Pigging stations. The Proposed alignment also meets the other
broader requirements of laying criteria of the pipelines. Accordingly, the present pipeline route has
been selected for the transmission of natural gas to various parts of Gujarat.
Cost of Project
The total estimated expenditure for laying of Anjar-Chotila pipeline project is approx. Rs 1058.40 Crores.
Need of Project
The project is required to meet the growing demands of Natural Gas in Gujarat. GSPL proposes to lay
dedicated Natural Gas transportation Pipeline from Anjar (Kutch) to Chotila (Surendranagar ) to supply
Natural Gas in most efficient manner. Pipelines are internationally recognized as the preferred alternative
for transport of fuels from the point of view of safety, economy and relative environmentally friendliness.
The pipeline will help in decongestion of roads, eventually minimizing road accidents and environmental
pollution that are generated by other means of transport.

DESCRIPTION OF THE ENVIRONMENT
AIR ENVIRONMENT
To establish the baseline status of study area, total 30 AAQ monitoring stations were selected, out of
which 21 along main pipeline route & around the SV stations along the pipeline route. In this region,
conventional air pollutants viz. PM10, Sulfur Dioxide (SO2), Oxides of Nitrogen, as well as
Hydrocarbons and Carbon Monoxide (CO), are identified for air quality assessment.
Along Pipeline route
The 24 hourly PM10 concentration varied in the range of 41-68 µg/m3 may be attributed to windblown
soil, unpaved road etc. in rural areas in the study region. The concentrations of SO2 were observed to
be varying in the range of 9-22 µg/m3. Similarly the concentration of NOx varied in the range 11-29
µg/m3 along the pipeline route.
The observed Total VOCs and Total Hydrocarbons concentration at all the locations were found non-
detectable. The observed carbon monoxide concentration at all the locations varied between 0.300-
0.489 mg/m3 which were found to be less than the NAAQS.
The total hydrocarbon concentration at all locations was observed to be non-detectable along the
pipeline route.
Around SV station
The concentration levels of PM10, SO2, NO2, CO were found to be in the range of 40-63 µg/m3, 8-27
µg/m3, 10-28 µg/m3, 0.307-0.475 µg/m3 respectively whereas Total VOCs and total hydrocarbons
were found to be non-detectable.
NOISE ENVIRONMENT
Total thirty (30) locations were identified based on the activities in the village area, traffic areas and
sensitive areas
Along Pipeline Route
Equivalent noise levels, Leq (Day) and Leq (Night) were monitored across the pipeline route. The
equivalent noise levels varied in the range of 57.8-64.8 and 35.8-40.3 dB(A) day and night time
respectively. Vehicular traffic is the major noise sources and contributes mainly to background noise
levels in the study area.
Along SV Stations:
Equivalent noise levels, Leq (Day) and Leq (Night) were monitored around the SV stations and
observed the range of 58.9-66.8 dB(A) and 35.2-40.1 dB(A) during day and night time respectively.
Noise level due to Traffic:
The national highways are passing through this region and having major traffic activities.
Agglomeration and congestion of traffic was observed on main roads and crossing of important
roads, near petrol pumps, market and Industrial areas. During survey period, traffic density at these
junctions was observed to be very high.

WATER ENVIRONMENT
The major drinking water source along the pipeline route is groundwater. Most of the villages are
having public tube wells and hand pumps for domestic use.
Physico-chemical parameters along with biological indicators of pollution have been used for
ascertaining the status of water environment along the pipeline route, and SV stations. In order to
determine the surface and groundwater quality, 2 sampling locations for surface water and 14
sampling locations for groundwater from various tube wells (TW), and bore wells (BW) covering a
total 16 sampling locations in the study area.
Water Quality Assessment
Surface Water Quality:
Surface water samples were collected from Machhu river and sea water near Haripur village. The
analysis results indicate that the pH ranged between 7.61 to 7.41 which are well within the specified
standard of 6.5 to 8.5. The TDS was observed to be 1150-37794 mg/l .The Total hardness recorded
was in the range of 310 to 1570 mg/l as CaCO3 .The nitrate was found to be in the range of 28.96 -
43.48 mg/l. The levels of chloride and sulphate were found to be in the range of 352.80-22688 mg/l
and 82-223.91 mg/l respectively. Heavy metals content (i.e. As, Al, Cd, Cr, Cu, Pb, Fe, Mn, Zn and
Hg) were found to be very low and within specified standards.
The overall surface water quality was found to be highly mineralized with respect to TDS, Hardness,
Chlorides and Sulphates. The nutrient load in terms of nitirate and phosphate was found to be high
whereas, organic load in terms of BOD and COD was found to be less indicating no organic load and
devoid of pollution. The high concentration levels of minerals might be due to creek water ingress the
source in high tide condition.
Groundwater quality
The analysis results of ground water samples indicate that the pH ranged between 7.1 to 8.35 which
are well within the specified standard of 6.5 to 8.5. The TDS was observed to be 203-1588 mg/l which
is within the permissible limit of 2000 mg/l. The Total hardness recorded was in the range of 128 to
582 mg/l as CaCO3 which is also within the permissible limit of 600 mg/l. The nitrate was found to be
in the range of 1.2-39.48 mg/l. The levels of chloride and sulphate were found to be in the range of
34.24-562.59 mg/l and 12.55-58.52 mg/l respectively. The levels of heavy metals content (i.e. As, Al,
Cd, Cr, Cu, Pb, Fe, Mn, Zn and Hg) were found to be within permissible limits.
Overall groundwater quality was found to be highly mineralized with respect to hardness, total
dissolved solids, chloride and sulphate. Nitrate concentration in some of the groundwater was found
to be high due to surface runoff carrying fertilizers used for agriculture purposes. Heavy metals were
found to be within permissible limits except Iron.
LAND ENVIRONMENT

ground truth and interpretation of satellite data. The outcome of the landuse study is presented in EIA
report.
Soil:
Soil was collected at different stretches along the pipeline route and around SV stations. Soil samples were
collected from 15 different locations along pipeline route and SV stations.
Physico-Chemical Characteristics
The texture of the soil was found to be silty clay, sandy clay and loamy sand in nature. Regular
cultivation practices increase the bulk density of soils thus inducing compaction. This results in
reduction in water percolation rate and penetration of root through soils. The bulk density of soils was
found to be 1.08-1.13 g/cc which indicates favorable physical condition for plant growth . The water
holding capacity of soil was in the range of 38.67-46.17%.
Chemical Characteristics
pH of soil in the study area was found to be slightly acidic to alkaline in reaction as pH was in the
range of 6.81-7.84.
The soluble salts were determined from soil extract (1:1), the soluble salts are expressed interns of
electrical conductivity (EC), the EC of the soil sample was in the range of 148.7-269.8 µS/cm. The
important cations present in soil are calcium and magnesium. It was observed that both calcium and
magnesium concentrations were in the range of 197.81-296.66 mg/kg and 80.25-180.54 mg/kg
respectively. Whereas chloride in the range of 160.51-240.48 mg/kg.
Amongst the exchangeable cations, Ca+2 and Mg+2 were found in the range of 96.44-146.47 mg/kg
and 37.11 to 86.92 mg/kg respectively along the pipeline route while sodium and potassium in the
range of 58.27-110.8 mg/lg and 74.88 – 120.7 mg/kg respectively.
Nutrient Status:
Organic matter and organic carbon present in the soil influence its physical and chemical properties
and is responsible for stability of soil aggregates. Organic matter and nitrogen were found in the
range of 2.28-2.88 % and 116.25-182.6 kg/ha. This showed that soil was moderately fertile in organic
and nutrient content.
BIOLOGICAL ENVIRONMENT
Study of biological aspects was made as per topography, land use, vegetation pattern, etc. The
biological survey was carried out by considering ecological sensitive receptors like forested area
(Protected forest and Social forest) in order to study existing status of floral composition and faunal
attributes, similarly biological survey was also carried out on non-forested area (agriculture field,
water reservoir, riverside, on hills, in plain area, village wasteland, block plantation etc. The biological
survey is mainly concerned at selected locations along the pipeline route of 500 m towards left and
right hand sides of proposed pipeline route and traversing area and 5 km periphery at stations.
Considering magnitude of impact and to know the existing status of biological environment at
immediate vicinity at station, 5 Km periphery along station was considered.

Survey along the pipeline route within the wild-Ass Sanctuary Area
Flora:
The natural terrestrial vegetation of the sanctuary and surrounding area area falls under “VI – B
Northern Tropical Forest” Sub type C-I Desert Thorn Forest (Kutch, Saurashtra, Gujarat). The forest
patches falling under this category have mono-dominant Prosopis juliflora and other Acacia spp.,
Euphorbia spp., Zyziphus mauritiana was also observed in these scrubs. The ground cover generally
is of Cassia auriculiformis, Zyziphus nummularis etc.
Permanent vegetation composed of xerophytic and consists of trees and shrubs up to 6m tall or
rarely more. It is characterized by arid vegetation dominated by Acacia spp., Capparis spp., Prosopis
ceneraria, Prosopis chilensis, Calotropis procera, Cassia auriculata, Cordia gharaf, and partly

Azadirechta indica. However, large open areas are extensively covered by the naturalized species
Prosopis juliflora which forms almost impenetrably thickets at the cost of natural vegetation.
Considering the species composition, the vegetation notably grouped under Type 6B/C1 – Desert as
per Champion and Seth (1968). These type of vegetation is closest to the degraded phase.
Hard wooded species like Acacia leucophloea spp. Predominate and peculiar characteristic of the
forest. The dominants vary from 4.5-10m in height and tend to be collected in clumps leaving bare
ground in between. Regeneration by root suckers is common, notably in Prosopis and Capparis.
Climbers are relatively numerous and also usually exhibit xerophytic adaptations. The woody growth
is of all sizes of Prosopis and Capparis from the trees down to the dwarf shrubs with no differentiation
in to storeys. The perennial grasses grow in clumps and tussocks. There is a thin growth of annual
grasses after the rains.
Stunted Acacia leucophloea, Acacia tortilis, A. nilotica, Prosopis cineraria are seen intermixed with
Azadirachta indica, Ziziphus spp. It is mostly invaded by Prosopis juliflora. It is a biotically controlled
community existing in a severely degraded state. Degraded scrub is the dominant vegetation type
throughout the study area. Zizyphus nummularia together with Calotropis procera are dominant
shrubs. Salvadora persica occur scattered in the scrub growth. Tribulus terrestris, Cenchrus ciliaris,
Aristida spp., Achyranthes aspera are dominant.
Fauna:
During survey indirect evidences in the form of dried pellets of wild ass were observed in notified
sanctuary area while direct sightings of wild ass seen near along Anjar – Dharngadhara Highway
near village Rapar which are almost 2.8 km away from the pipeline route. Nilgai and Jackal are very
common inhabitant in the area. The area supports variety of local as well as many migrants avifauna
species.
Salt pans
The proposed natural gas pipeline partly crosses the saltpans. Saltpans are nothing but typical tide
water impounded enclosed system adjacent to creek environment. They are characteristically
exposed to a wide range of environmental stress and perturbation which manifest mainly through
salinity changes. However, saltpans are immature ecosystem as compared with a typical marine
system and harbour a high proportion of opportunistic species. Species diversity is directly linked with
salinity. Hence the higher the salinity, the lower the species diversity and simpler the structure of the
ecosystem.
The abandoned salt pans occupy significantly large area with poor diversity. A few halophytes such
as Suaeda fruticose and Suaeda maritima were found abundant. The other herbaceous species
which grow along the bunds include Aleurops lagopoides, Aerva javanica, etc. These saltpans serve
as feeding grounds for a variety of resident as well as migrant birds.
Medicinal Plants: Wild plants of medicinal value are distributed in the area. Some of the plant
species having medicinal value like Abutilon indicum, Aerua javanica, Aerva lanata, Amaranthus
virides, Ocimum sp., Tribulus terrestris, Suaeda nudiflora, Sida acuta, etc. were quite common in
study area.
Faunal Diversity
Wildlife present on the proposed pipeline project site was identified through a combination of direct
observation and indirect indicators including vocalizations and signs (eg. scat, tracks). Wildlife survey

Maximization of the reuse of hydrotest water to the other section of pipeline.
Major crossing job will be carried out during dry season
Ensuring supply of portable toilet for construction staff.
Preparation of sock pit & septic tank.
Operation Phase
There will be no requirement of water for the pipeline operation along the route. However, marginal
water will be required for domestic use at the SV stations during operational phase. The total water
requirement during operational phase is estimated approx. 20 KLD.
Impact
Domestic waste water.
Mitigation Measure
Preparation of sock pit & septic tank for disposal of sewage.
Installation of rainwater harvesting structures at Stations.
LAND ENVIRONMENT
Construction Phase
Impact
A very marginal quantity of earth excavated for terminals and pipeline lying will become
surplus after installation of the pipeline and may be required for disposal. However, the
aesthetics of the pipeline RoU and soil quality will not be affected.
The pipeline route Anjar-Chotila passes through agriculture land at most of the places. Some
part of the pipeline route passes through the sandy soils with minimal vegetation.
Major land use along the proposed pipeline route is agriculture / barren land thus there will be
very less impact on land-use pattern along the pipeline route. No change in land use pattern
along the pipeline route is envisaged as the land will be restored to its near original condition
and hand over to land owner after laying the pipeline.
Land will be permanently acquired for all stations (surface facilities).
Mitigation Measure
In the adjoining areas soil type is silty, sandy, Loamy, clay followed by sandy loam with
medium percolation. However, every precaution will be taken to avoid spillage on soils during
construction phase to protect groundwater quality and soil microbiology in pipeline route and
SV stations
Construction activities may be carried out within the ROU of pipeline.
Excavated top soil will be segregated and restored back to near to original state after
completion of pipeline laying.

Executive Summary
13
A record with respect to quantity, quality and treatment / management of solid/ hazardous
waste shall be maintained.
Disposing hazardous wastes to authorized vendors as per legal provisions.
Any kind of materials resulting from clearing and grading will not be deposited on temporary or
permanent basis in the approach roads, streams, ditches and any other position which may
hinder the passage and / or natural water drainage.
On completion of construction works, all temporary structures, surplus materials and wastes
will be completely removed from the site to avoid future land use incompatibility. During of
construction, waste on agricultural land will be prohibited.
The pipeline corridor for laying the buried pipeline will be about 20m wide and the total
estimated corridor length is about 196.14 km. This will be obtained on a right of use (RoU)
basis. The land will be restored to near original condition after the pipeline is laid, hence
impact on land use pattern due to laying of pipeline will be marginal and reversible
Standard construction procedures will be implemented to ensure that the impact on surface
drainage pattern and soil erosion is kept minimal. This will necessarily include avoiding
blockage of natural surface drainage and developing appropriate drainage system in areas
where it is unavoidable.
The current topography and land usages of the project area will not be adversely affected due
to limited constructional activities for the project.
Operation Phase
The land on permanent basis is required at SV stations only. The land requirement at each
associated facilities such as Sectionalized valve Stations /Tap-off/Metering /Receiving/
Dispatch/Intermediate Pigging stations is approximately 0.36 Ha. Thus the total area requirement for
11 associated facilities (SV/IP/RT/DT) is 3.96 Ha approximately..
Impact
There is a potential for impact on soil quality due to spills during pigging of pipelines, handling
storage or hazardous waste (used oil) & chemical, if any.
Mitigation Measures
Proper collection, transportation and temporary storage of pigging wastes.
Adequate reuse of used oil.
BIOLOGICAL ENVIRONMENT

ANALYSIS OF ALTERNATIVES
Technology Alternatives
Pipeline laying and transportation of natural gas in an established practice worldwide. Latest
Technology and construction machinery will be used for pipeline construction so that minimum
damage will done to the surroundings. Gas pipeline network will be monitored continuously using
SCADA system.
Alternatives for Project site
The proposed evacuation pipeline route would not pass through any environmentally sensitive aeras,
(except wild ass sanctuary, Hadkiya creek and salt pan crossing), human habitations, archeological
monuments. The major land use along the proposed pipeline is agricultural, national and state
highways. There are no established breeding grounds and migratory routes along the pipeline route.
During Reconnaissance, Route Verification and Validation, a number of development, obstacles,
forest land, villages (dwellings), were noticed which needed to be avoided. Therefore new pipeline
route was aligned keeping in view the about mentioned aspects.
Environment Monitoring Programme
The proposed Anjar-Chotila pipeline runs underground at minimum depth of 1-1.2 m and is controlled
by SCADA system which allow continuous monitoring and rapid closure of valves, therefore there are
very rare chances of leakage and therefore regular monitoring of eleven SV stations will be done to
assess the surrounding environmental quality.
PROJECT BENEFIT
The pipeline, during construction and operation phase will generate direct and in-direct
employment as there will 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.
Proposed Natural gas pipeline developmental project will result in considerable growth of
service sector and will also generate new industrial and business opportunities in the areas
through which it will pass Small and medium scale industries may also be developed as a
consequence.
The proposed Natural gas pipeline will also lead to investment by major industries in Gujarat.
Investment by big industrial players will generate employment for the local population.
Due to easy availability of Natural gas, emissions from the same industrial setups will also be
reduced to a large extent.
Transportation by pipeline is comparatively less expensive than the other modes of transport,
both in the capital and operating costs. If a good network of pipelines is implemented
throughout the country, this will ensure that the pipeline-transported products will be available
to the consumers at a lower cost than alternate modes of transport
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.
Pipelines are internationally recognized as the preferred alternative for transport of
hydrocarbons from the point of view of safety, economy, reliability, and relative
environmentally friendliness.
ENVIRONMENTAL COST BENEFIT ANALYSIS
As a consequence of rapid industrialization in India, fuel needs are increasing at a rapid rate and
supply demand gap is widening. Pipelines are internationally recognized as preferred alternative for
transport of fuels from the point of view of safety, economy and relative environmentally friendliness.
The cost of this project is estimated to be 1058.40 crore including contingency cost to take care of
any inflation and exigencies. These cost estimates are primarily based on cost of piping material,
equipment and facilities, RoU and pipeine laying cost incurred by GSPL for its recently implemented
pipelines and market enquiries on latest prices.
Besides the tangible benefits, the project has got number of intangible benefits like minimum
emissions of the green house gases, no adverse impact on environment, socio-economic benefits to
the local people and the region and enhancement of the fuel/energy for the country. The
establishment of Anjar-Chotila Pipeline, when operated will provide significant supply of fuel to the
consumers.
Health, Safety and Environmental Management System
The objective is to identify any significant HSE risks, particular to this project which cannot be
adequately managed by the normal risk management processes and construction HSE
procedures. Following the one-off overall construction HSE risk assessment, a systematic
assessment of all health, safety and environmental risk shall be carried out during the
planning of all construction activities which will include the following:

1.0 INTRODUCTION
1.1. PROJECT PROPONENT
As a fuel, natural gas competes with a range of alternative products such as coal and lignite as well
as petroleum products such as liquefied petroleum gas, naphtha, high speed diesel, light diesel oil
and fuel oil. However, due to lower fuel operating costs and better combustion characteristics, natural
gas has distinct economic advantages over other sources of energy. In addition, natural gas has
substantial environmental advantages over other energy sources, due to lower emissions.
The development of proposed project is for natural gas transportation within state of Gujarat. The
proposed project is planned to be developed by M/s Gujarat State Petronet Limited (GSPL).
M/s GSPL, a Government of Gujarat undertaking is one of the leading company in the field of Natural
Gas transmission line. It is in the process of expanding its pipeline network all over the Gujarat State
to take care of future demand-supply gap to fulfill the requirements of various consumers throughout
Gujarat. It is first company in India to transport natural gas on open access basis and is a Pure
Natural Gas Transmission Company.
GSPL is a pioneer in developing energy transportation infrastructure and connecting natural gas
supply basins and LNG terminals to growing markets. It is continuously expanding its pipeline
network in Gujarat to reach the demand centers by laying gas pipeline network. The company has
developed requisite expertise and confidence with proven project management competencies.
GSPL is the second largest Natural Gas transportation company in India and presently operating
pipeline network in the state of Gujarat.
1.2. PROJECT BRIEF
In order to facilitate the augmentation of gas supply to various consumers in Gujarat, an analysis of
the infrastructure requirements has been carried out and based on such analysis, it was decided to
create suitable infrastructure facilities like LNG import terminal and creation of network of high-
pressure gas transmission pipelines to facilitate transportation of gas from point of supply to points of
demand related to the consumers/industries (domestic, petrochemicals, power plants and other allied
industries) which will help to increase the economic output of the region and thereby the nation.
Moreover, being a green gas, it is environment friendly and the cost of transportation will be
drastically reduced as compared to other means of transportation and supply to the consumers will
be in cheaper rate.
The project is required as existing pipeline from Varsamedi (Anjar to Chotila) will not meet the total
transportation volume requirement from the GSPC LNG Terminal. GSPL would be the only company
to have pipelines in this section for transportation of natural gas for which M/s Gujarat State Petronet
Limited (GSPL) has received the Authorization from PNGRB (Petroleum and Natural Gas Regulatory
Board) for the development of following project for the transportation of Natural Gas with a
permissible RoU width along the pipeline route (Annexure I).
GSPL proposes to lay a network of Gas Pipeline for the supply of Natural Gas to various consumers
situated at Gujarat state. There are numbers of supporting industries that have been developed in
Anjar, Gandhidham, Kandla & Bhuj region of Kutch district. In order to fulfill the requirement of natural
gas in future, GSPL proposes to lay a pipeline for the supply of Natural Gas from Anjar to Chotila.
The proposed Anjar to Chotila Pipeline will originate from village Ratanpar-(GSPL's ARPL SV-8 TOP-
8), Taluka-Sayla of district-Surendranagar, pipeline stretch will cover a distance of 196.14 km,

There will be 11 surface facilities (SV/IP/RT/DT) along the pipeline route at designated locations for
the proper maintenance of the pressure and flow of natural gas and accordingly distribution. The flow
of the gas through pipeline will be approx. 23.13 MMSCMD. The proposed pipeline will help to create
network in the region for supply to the consumers which will help to increase the economic growth of
the region.
2.2 JUSTIFICATION & NEED OF PROJECT
The project is required to meet the growing demands of Natural Gas in Gujarat. Thus GSPL proposes
to lay dedicated Natural Gas transportation Pipeline from Anjar (Kutch) to Chotila (Surendranagar ) to
supply Natural Gas in most efficient manner. Pipelines are internationally recognized as the preferred
alternative for transport of fuels from the point of view of safety, economy and relative
environmentally friendliness. The pipeline will help in decongestion of roads, eventually minimizing
road accidents and environmental pollution that are generated by other means of transport.
As India has witnessed rapid urban and industrial growth in the past two decades, and with the
country’s current liberalization policy this growth is expected to accelerate and need additional energy
for development. As a consequence of the rapid rate of industrialization in India, fuel needs are
increasing at an equally rapid rate and the supply-demand gap is widening and steps must be taken
to address this issue. Overload transport of fuels by trucks is uneconomical, unsafe, and is a
contributor to environmental degradation in terms of the fuel consumed and pollutants released by
vehicles in transit and by accidents and spillages (common on Indian roads).
Pipelines are internationally recognized as the preferred alternative for transport of fuels from the
point of view of safety, economy and relative environmentally friendliness. The qualities of
underground pipelines that make them desirable from these angles are that they are buried
underground (at minimum depth of 1-1.2 m) and are controlled by SCADA systems.
The road and rail transportation systems, at present, have to share the load of transporting raw
materials and finished products from the supply centers to the demand / consumer centers. Rail
transport is utilized for carrying bulk of the petroleum products throughout the country and the
balance quantity is transported by road. This is stretching the transport sector capacity and hiring the
movement of other essential raw materials and products.
Transportation of gas by underground pipeline is comparatively less expensive than the other modes
of transport both in the capital and operating costs. If a good network of pipelines is implemented
throughout the country, this will ensure that the pipeline transported products will be available to the
consumers at a lower cost than alternate modes of transport.

2.4.2. Phase of Project
2.4.1.1 Construction Phase For Pipeline Laying:
The pipeline construction is proposed to be carried out through deployment of 2 to 3 spreads. The
sequence and methodology of construction of new pipeline is given below:
1. Clearing and Grading - A 20 m wide Right of Use (RoU) area will be cleared off vegetation
and other obstacles such as boulders.
2. Stringing - Pipes are transported to the site on trucks will be offloaded using side booms.
Pipes are then strung adjacent to the trench. Trailers and cranes will be used for maneuvering
of pipes. This activity may be done before or after trenching.
3. Trenching - Trenchers and backhoe type excavators will be used to dig the trench for laying
the pipeline. The topsoil in agricultural areas will be removed and stockpiled for restoration.
The excavated sub-soil will be stockpiled separately for backfill.
4. Bending - Pipes will be bent using a bending machine to the appropriate angle to match the
vertical and horizontal alignment of the trench.
5. Welding - Welding will be done using conventional manual/ semi-automatic welding involving
a crew of welders and fitters.

6. Non-Destructive Inspection - Mechanized Ultrasonic Testing (MUT) is the specified method
to be applied for the execution of NDT. Each field weld will be 100% radiographed to test for
soundness of the weld in compliance with specifications. NDT and its evaluation shall be
performed in accordance with API Standard 1104.
7. Coating - After welding at each weld joint, coating of field joints of bare pipes and the repair of
coating shall be done
8. Lowering - Padding will be provided, wherever required, in the bottom of trench to prevent
damage to the coating.
9. Burial - General burial depth of the pipeline along the route will be with a minimum 1.0 m
cover. Burial cover will be compacted to avoid future erosion by all weathers.
10. Backfilling - The excavated sub-soil will be returned to the trench. The topsoil, which has
been preserved on the side of the ROU, will be spread over the filled up trench. A crown of
soil will be kept on top of the trenched portion to allow for future settlement. Backfilling will be
managed so that damage from sizable rocks is not used or any other materials that may
damage the pipeline.
11. Crossings - The method used for the crossing of waterways and other infrastructure facilities
will vary from place to place depending on the environmental setting and the geo-technical
features of the area.
For the critical river/canal crossings Horizontal Directional Drilling (HDD) will be adopted and
at other places open cut method shall be used based on topography of the crossing by taking
necessary statutory permission
12. Restoration - Restoration of the ROU will be conducted progressively following the
completion of construction work. This will involve removal of foreign materials such as
construction debris and wastes. The ROU will be returned to its original condition by
spreading the topsoil over the areas from where it was stripped, so that agricultural activities
will be restored. Special focus will be given to restoration of side slopes and beds of natural
water body crossings.
13. Pipeline warning markers–In the final stages of construction, warning marker posts will be
erected indicating the location of the pipeline and the crossing of other pipelines, cables and
features. A marker tape will be placed in the trench 500 mm above the pipeline to indicate to
future excavators that a pipeline is below and that they are nearing.
2.4.1.2 Construction Phase For associated facilities
At SV station sites, the construction will be undertaken within the station. The other steps of
construction shall be more or less same as the pipeline given below:
Clearing of the identified location
Modification of the boundary wall wherever required.

2.4.1.3 Operation Phase For Pipeline
The activities involved in the operational phase of the project are as follows:
1. Commissioning of the pipeline: Prior to commissioning of the pipeline, a number of pre-
commissioning operations like cleaning and hydrostatic testing of pipeline, starting of
mechanical and rotating equipments will be carried out. After successful pre-commissioning
activities, the pipeline shall be commissioned for transfer of Natural Gas.
2. Utilities: The water requirement in the stations during the operational phase will be met by
bore wells or outsourced through road tankers.
3. Normal operation: During the normal operation of pipeline, the activities will be mainly
confined to the battery limits of terminals.
4. Infrastructure facilities: Infrastructure facilities to support the anticipated worker population
and the project like municipal facilities, firefighting facilities, sewerage maintenance, power
supply, water supply and maintenance etc, will be provided where ever required.
5. Post construction protection system: The entire pipeline will be protected against external
corrosion by a cathodic protection system. Pipe external coating will be done at the coating
plant before it is transported to site.
6. Inspection of pipeline: Regular inspection of the pipeline shall be carried out as per standard
practices. A SCADA monitoring and control system will be utilized ensuring effective and
reliable control, management and supervision of the pipeline network system. In addition to
SCADA, physical patrolling along the pipeline route will also be carried out by line walkers
daily.
2.4.1.4 Operation Phase For Associated Facilities:
Once the pipeline is commissioned, there will be a regular visit by the operation engineers as per
drawn up schedule to ensure safe operations. Inspection work will be undertaken on a routine basis.
Inspection pigs will be propelled in the pipeline once in two years to check the health and dimension
of the pipeline.
2.4.3. CONSTRUCTION MATERIAL
Carbon steel pipelines of 36’’diameter will be laid for a total length of 196.14 km. Pipe material and
pipe type are API 5L Gr. X-70 PSL-2 and LSAW/HSAW respectively. It will be commissioned as per
PNGRB guidelines. For SV stations construction materials such as MS, sand/ soil, cement, diesel oil
etc. will be procured from local sources.
GSPL will follow the codes and regulations to meet National and International standards.
2.4.4. RESOURCE OPTIMIZATION / RECYCLING AND REUSE ENVISAGED IN THE PROJECT
Resource Optimization / recycling and reuse envisaged in the Project
All the construction and testing equipment used in the project will be put to use in other
similar project once the project is completed.
Water used for hydrostatic testing of pipes during commissioning will be stored and used for
other pipes.

Rain water harvesting and recycled water will be used for sanitary purposes, green belt
development and gardening purposes as practicable.
2.4.5. WATER SOURCE & CONSUMPTION
The source water requirement for pipeline construction is minimum, which will be met through Road
tankers from available sources in the nearby area. However, during operation phase water will be
sourced from bore or dug well inside the SV Stations for domestic purpose and tree plantation
depending upon the requirements.
2.4.5.1. WATER CONSUMPTION
Water consumption will be Max. 50-60 KL/day during Construction period, and during operations it
will be approx. 20 KL/day.
2.4.5.2. WASTEWATER GENERATION
During construction phase the liquid wastes generated from the construction camp will be discharged
through soak pit/septic tank. Similarly the domestic waste generated from the SV stations will also be
sent to septic tank/ soak pit. During construction, the marginal liquid effluent or spoiled / drained
lubricants oil generated at construction camp will be disposed off as per SPCB guidelines.
No waste water on continuous basis from pipeline operations is envisaged. During operation phase
domestic waste water will be generated at Stations and that will be disposed to the septic tank/ soak
pit. The waste water generated during the hydrostatic testing of euipment & pipeline is temporary &
one time activity. The same water will be reused for multiple tests in other sections. The residual
hydrotesting waste water at the end of test will be non-toxic & disposed off suitably.
2.4.6. ELECTRICITY (POWER REQUIREMENT)
Required power for SV / IP / Dispatch / Receiving shall be drawn from nearest local power source of
the state Electricity Boards. Approx. 11 Nos. of DG sets with each have capacity of 50 KVA will be
provided. However, DG sets will be kept as standby at Stations.
2.4.7. SOLID AND HAZARDOUS WASTES
Solid Waste: Marginal amount of solid watse will be generated at the camp site along the pipeline
route, and same will be disposed as per SPCB/CPCB guidelines. Quantity of wastes generated is
expected to be 0.2-0.5 kg/per capita/day during construction activities (plastics, waste papers and
card board, etc). Solid wastes generated will be properly collected, segregated and reused / disposed
off appropriately. On completion of construction works, all temporary structures, surplus materials and
wastes will be completely removed and land will be reinstated to near its original state. Dumping of
construction waste on agricultural land will be prohibited. Only excavation soil will be generated
during construction, which will be reinstated to near original condition after laying the pipeline.
Hazardous waste: generated at the time of construction will be used oil, chemical & lube oil barrel,
batteries, welding electrodes etc and will be disposed as to SPCB authorized recycler/dealer/TSDF
sites.

Hazardous wastes generated during operational activities in the form of spent oil from DG sets,
equipments & pigging waste etc., will be reused as lubricant and drums will be disposed off as per
SPCB/CPCB guidelines.
The detailed estimation of solid waste generation during construction and operation phase is as
follows:
SOLID WASTE GENERATION (Kg/day)
Sr. No. PARTICULARS Workers/Manpower SOLID WASTE GENERATION (Kg/day)
A. PIPELINE ROUTE
Construction Phase 100 100 X 0.5 = 50 Kg/day
B Operation Phase 06 0.5 X 06 = 03 Kg/day
C SV STATION (11 Nos.)
Construction Phase 10 x 11 = 110
(5 Skilled, 3
Unskilled and 2
security)
110 x 0.5 = 55 Kg/day
D Operation Phase 2 x 11 = 22 22 x 0.5 =11 Kg/day
A. Along the pipeline route:
The domestic solid waste generation during construction phase will be 50 Kg/day and during
operation phase it will be 3 Kg/day so the total domestic waste generation 53 Kg/day along pipeline
route
B. In SV station:
The domestic solid waste generation during construction phase will be 55 kg/day and during
operation phase it will be 11 kg/day so the total domestic waste generation will be 66 kg/day.
2.4.8. TRANSPORTATION
It is intended to make maximum use of the existing infrastructure and augment/ strengthen existing
roads, wherever required. Hence no major changes are envisaged due to this buried natural gas
pipeline project.
2.4.9. REHABILITATION AND RESETTLEMENT (R & R) PLAN
(i) Policy to be adopted (Central / State) in respect of the project affected persons
including home ousters, land ousters and landless laborers (a brief outline to be given)

The proposed pipeline will be a buried underground 1.0 to 1.2 and will be laid as per latest additions of
OISD-226 & ASME B 31.5 and other applicable statuary standards and best available technology. It will be
commissioned as per PNGRB guidelines. Due care is taken in selection of pipeline route by avoiding
environmentally sensitive areas, Forests and National Parks, etc. However pipeline passes through
Hadakiya creek and wild Ass Sanctuary which is unavoidable.
