Preface
World bank financed Shanxi Gas Utilization Project consists of 6 subprojects, and 2 of which
are CHP subprojects, namey the Xiyang County CHP Subproject and Baode County CHP
Subproject; 4of which are Urban Gas pipeline network subproject, namely the Changzhi
County Gas Utilization Subproject, Xiangyuan County Gas Utilization Subproject, Tunliu
County Gas Utilization Subproject and Qingxu County Gas Utilization Subproject. Shanxi
Guoxin Energy Development Group Co., Ltd. is the Project loan subject responsible for the
smooth implementation of the project.in the financing, project construction, staffing and other
aspects.
The project entered the implementation phase in 2014. In November 2016, Shanxi Guoxin
Energy Development Group Co., Ltd. applied for interim adjustment to the bank's inspection
team, planning to cancel the phase II projects of Changzhi, Xiangyuan, Tunliu pipeline
network, and increase the Yangcheng county gas utilization project, with Shanxi Guoxin
Zhonghaosheng Natural Gas Co., Ltd.as the main body of construction.
The 3 Gas Utilization Subprojects of Changzhi County, Tunliu County and Xiangyuan
County in the World Bank Financed Shanxi Gas Utilization Project are planning a total of
$16.5 million for World Bank funds, the Feasibility study approved the design and
construction of pipeline length of 222.3 kilometers, with the Changzhi County subproject 52.7
kilometers (25 km in phase I, 27.7 km in phase II), Tunliu County subproject 86.4 kilometers
(40 km, in phase I, 46.4 km in phase II), Xiangyuan County subproject 83.21 kilometers (44
km, in phase I, 39.21 km in phase II). All 3 subprojects are planned to implement in two
phases. At present, the first phase of the world bank project has completed all procurement
bidding, using world bank loans funds of 62.44 million yuan.In recent years, the economic
environment and market environment in Shanxi have changed greatly. The decline of coal
industry, the decrease of resource utilization, the slow development of gas market, and the
relocation of villages and towns have caused insufficient demand for gas market in Changzhi,
Xiangyuan and Tunliu counties.For the rational allocation of world bank funds, to avoid
waste of public resources, Coal Bed Methane (Natural Gas) Co., Ltd proposed to adjusted the
phase II of the world bank project on a comprehensive basis: Cancel the construction of total
of 113 kilometers pipeline of 3 subprojects in Changzhi, Xiangyuan and Tunliu, propose the
Yangcheng County gas utilization project instead.
At present, natural gas use in Yangcheng County has a good foundation, 60 thousand
households and more than 200 industrial and commercial users and the public welfare
institutions use natural gas in the 6 villages and towns of Yangcheng County.
Yangcheng County gas utilization project will build a new urban medium pressure pipeline
network 27.79 kilometers, and upgrade some of the arlier constructed gas facilitiese with
hidden danger. The subproject construction unit is Shanxi Guoxin Zhonghaosheng Natural
Gas Co., Ltd.

1.1 Project Background and Origin
Lying in the heart of the Yellow River basin, Shanxi Province neighbors Hebei Province in
the east with the Taihang Mountain as a natural barrier, faces Shaanxi and Henan Provinces in
the west and south across the Yellow River, and adjoins Inner Mongolia Autonomous Region
in the north with the Great Wall as the boundary. It is named for its location in the west of
Taihang Mountain. The province covers a total area of 156,700km2, with a total population of
36.108 million people. It has 119 counties in 11 prefecture-level cities, including 85 counties,
11 county-level cities and 23 municipal districts.
Shanxi Province’s main energy consumption lies on coal. The coal consumption takes up
more than 98% of the total consumption. As either a major province of resources or a main
province of energy consumption and emission that shoulders arduous energy conservation and
emission reduction tasks, Shanxi Province has an urgent need for changing the energy
consumption structure dominated by coal, and gradually achieving the diversification of
energy consumption. To change the energy consumption structure and realize the leap from
coal to gas, Shanxi vigorously carried out “Building a Gas-fueled Shanxi” project during the
"12th Five-Year (2011 -2015)" period. As of August 2016, Shanxi province " Building a
Gas-fueled Shanxi " project completed a total investment of 25.5 billion yuan, the cumulative
gas supply reached 15.6 billion cubic meters, gasfueled area covering the province's 104
counties (cities, districts), the gasification rate of 52%, far exceeding the national average.
Successful implementation of Building a Gas-fueled Shanxi has played an important role to
complet the state issued emission reduction targets, improve the environmental quality of
Shanxi Province, and promote regional economic development in the "12th Five-Year"
period.
To continue to consolidate the results of the "12th Five-Year " period, the outline of the 13th
Five-Year Plan (2016-2020) for National Economic and Social Development of Shanxi
Province put forward that "Spare no efforts to promote green development.Adhere to the basic
state policy of conserving resources and protecting the environment, adhere to sustainable
development, and vigorously promote the energy revolution". The Outline also proposed to
accelerate the construction of gas pipeline network, and strive to achieve full coverage of the
province's network. By 2020, the total mileage of the provincial pipeline exceeded 15
thousand kilometers".
As the main force and leader in “Building a Gas-fueled Shanxi”, Guoxin Energy spares no
effort in the Project under the context that transformation and comprehensive reform
experimental areas are established in the province.So far, Guoxin Energy has been listed as
one of the 12 key provincial-level pilot enterprises by CPC Shaanxi Provincial Committee
and Shaanxi Provincial Government; the Project of “Building a Gas-fueled Shanxi” also has
been listed as one of the key 30 provincial-levelprojects.

WB Financed SGUP is an important component of “Building a Gas-fueled Shanxi”. Upon
completion, the Project will be conducive to improve the current energy consumption
structure overly dependent on coal in the locality, turn the main energy consumption of
resident and industrial users into clean energy gas and power, enhance the energy utilization
efficiency, promote energy conservation and emission reduction, and improve the
atmospheric environment, public quality of life and health level, and even plays an important
role in the sustainable economic and social development of Shanxi Province.
World Bank Financed Shanxi Gas Utilization Project was planning to built 2 CHP
subprojects,and 4 Gas utilization subprojects. In recent years, the economic environment and
market environment in Shanxi have changed greatly. The decline of coal industry, the
decrease of resource utilization, the slow development of gas market, and the relocation of
villages and towns have caused insufficient demand for gas market in Changzhi, Xiangyuan
and Tunliu counties. The phase II of the three subprojects, Changzhi, Xiangyuan and Tunliu,
no longer have the demand for gasification. For the rational allocation of world bank funds, to
avoid waste of public resources, Guoxin Energy plan to cancel the phase II construction of 3
subprojects, and propose to implement the Yangcheng County gas utilization project.
After acceptance of the EIA commission, in November 26, 2016 we conducted a detailed field
investigation along the pipeline. On the basis of various types of relevant information, such as
revised feasibility study reports, social evaluation reports and resettlement plans, etc.,
reference of the comprehensive environmental impact assessment report of World Bank
Financed Shanxi Gas Utilization Project, and continuous communication with related units,
finally, completed the preparation of this report.

1.2 Objectives of Environmental Impact Assessment
(1) Through environmental impact assessment on the proposed project, we have learned about
the current natural and social environmental quality in the plant area and areas along the gas
pipeline network, determined the regional impact scope and impact degree of project
implementation, and demonstrated the rationality of the site and pipeline route selection plans
from the perspective of environmental protection, so as to provide decision-making basis for
the implementation of the Project.
(2) An analytic demonstration is made on the feasibility and rationality of engineering
contents proposed in the engineering design documents, in order to propose environmental
protection measure plans and suggestions for mitigating and avoiding environmental harms.
Meanwhile, considerations are given to strengthen or improve the plans or suggestions for
positive environmental impacts of the Project, and provide feedback and guidance to
-

engineering design, so as to realize the synchronic development of the project construction
and environmental protection measures, minimize the negative environmental impacts, and
promote the harmonious development of the project construction in terms of economic benefit,
environmental benefit and social benefit.
(3) Efforts are made to assess positive and negative impacts arising from the project
implementation, and encourage residents living along the pipeline to take an active part in the
project demonstration by means of public investigation, public notification on journals and
websites, publicity announcement, telephone consulting and symposium for public
participation, encourage residents living along the pipeline to take an active part in the project
demonstration, so as to make the demonstration process and assessment conclusion more
democratic and scientific, and play a positive role in publicizing environmental protection
laws and regulations and enhancing the public awareness in environmental protection.
1.3 Screening of Environmental Impact Assessment Factors
1.3.1 Identification of Environmental Impact Factors
The project is relatively simple. Their negative environmental impacts are mainly
concentrated in the construction stage. Because there are a smaller number of workers on the
same site in the same period, the construction camp is not required. In the construction stage,
their impacts include construction dust, materials transportation and storage, pipeline welding,
tail gas of oil-fueled machines, and borrowed and discarded earth. The components have
slight negative impacts on ambient air, land vegetation and nearby residents in the
construction stage. Upon completion of the construction stage, these negative impacts will
disappear. Despite such potential risks as explosion and fire disaster in the operation stage, the
subprojects would still have positive environmental impacts as a result of replacing coal with
gas. According to above analysis, a recognition matrix is developed for environmental
impacts of the project. See Table 1-2 for details, and Table 1-3 shows the indentification
results of environmental impact factors of the project

3.2 Construction Plan and Method
This is a natural gas pipeline project, no need for the the gate station, regional regulator
station engineering. The construction site should be cleaned up before pipeline construction;
The excavation of pipeline ditch adoptes single side dump, assembling and welding should be
done on the top of ditch. After the completion of the trench excavation, road crossing, river
crossing and other basic work, in accordance with the construction specifications, the pipeline
will be sent to the site for welding, pressure testing, interface corrosion prevention, and then
lowered down into the pipe trench.
The project adopts directional drilling to cross the ditch due to the stone masonry slope
protection, and adoptes direct excavation to cross the river. Concrete pressure block shall be
added to the pipe section to stabilize the pipe. The buried depth of the pipeline is in the stable
layer of the river bottom; The buried depth of pipe top is about 1m below scouring layer; The
Pipe jacking should be adopted to cross roads.
After the above construction is completed, the pipeline pressure test will be carried out.
The project uses clean water for atmospheric pressure test, and then backfill soil, clean up the
site, restore the landscape, and restore the vegetation.

3.2.2 Construction Methods
During the pipeline laying of the project, the direct excavation method is adopted to lay the
crossing works including river, channel crossing and highway crossing. The construction
methods are stated as follows:
1、Roads Crossing
Roads the pipeline engineering goes across include national roads, provincial roads and rural
roads. The engineering for crossing roads adopt the pipe jacking method. The pipe jacking
method doesn’t destroy the road pavement, or block traffic, with small perturbed surface and
slight environmental impacts. The construction method and machinery of pipe jacking method
are as follows:
(1) Construction method: first of all, set up the pedestal and install hydraulic jack in the
operation pit to penetrate tool pipe or heading machine through the earth to the receiving pit
and lift up them by using the propulsive force of main jack oil tank, pipeline room and relay
room; and then follow the tool pipe or heading machine to jack the prefabricated section of
pipe into the ground and bury the pipe between the two pit.
(2) Construction machinery: head (including small oil jack), oil press, main jack oil tank,
bridge crane (hoisting machine), resistance box and other power-supply units, electric welder,
measuring apparatus, pipe-like track, jacking block and back.
2、Channel Crossing
-
29
The project pipeline goes across the channel once. The pipeline construction adopts the direct
excavation method. As for Zhujiachuan River, Songxi River and Zhanghe River, the crossing
engineering adopts the directional drilling method, which is featured by short construction
period, small site disturbance and slight impacts on surroundings and can ensure the buried
depth of the pipeline. Construction method and machinery of directional drilling are as
follows:
(1) Construction method: first, make use of existing roads to transport equipment to the
construction site, and then conduct the excavation of slurry pond in drill site; meanwhile,
calibrate the position of main equipment with gray lines, and then place main equipment in
correct place at time of equipment access; start the construction of guide hole according to the
requirements of codes and design, and then start the construction of pre-reaming hole and
pipeline back dragging in order; after crossing, put equipment in order, clean the construction
site; after mud sedimentation, conduct clean-water discharge and backfill mud with earth to
restore landscape.
(2) Construction machinery and material: drill and drilling bit, back reamer, drill stem and
other accessory equipment, clay, power generator, blender and water pump.
3、River Crossing
(1) Construction method: The pipeline of the project crosses Huoze River once and Jina river
once, both are seasonal small rivers. Pipeline construction adopts the excavation method when
crossing river, and in the first, dry season shall be selected, rainy season shall be avoided; If
there is water flow in the river during construction, the river should be cleaned first, then one
side should be enclosed for diversion and the other side be excavated. After completion of the
whole construction, the river channel should be cleaned.
(2) Construction machinery
Excvavtors, cutting machine and shovels.
4、General routes
Pipe construction adopts the excavation method, which is featured by simple and direct
construction and low construction cost and has no impacts on revegetation and land
reclamation after earth backfilling. Therefore, general pipe section of the subproject adopts
the excavation method. As for excavation method, the Pipeline trench shall be excavated
according to the plane position and elevation stated in the design. In case of manual
excavation without Groundwater, the reservation value of trench bottom shall be 0.05-0.10m;
in case of mechanical excavation with Groundwater, the reservation value of trench bottom
shall be not less than 0.15m. Conduct manual bottom cleaning to elevation before pipeline
installation, and then start pipeline construction.

(1) Pipe trench backfilling
The pipe trench backfilling shall adopt fine earth to fill the pipe bottom and both sides of the
pipeline first, and then backfill the pipeline to 0.5m above the top of the pipe. The backfilling
soil on both sides of the pipe and 0.5m above the top of pipe shall not include gravel, brick,
litter and other sundries and shall not use frozen soil. The backfilling soil shall be tamped
layer by layer, with the layer thickness of 0.2-0.3m. The backfilling soil on both sides of the
pipe top and 0.5m above the pipe top must be tamped manually. When the height of
backfilling soil exceeds 0.5m of pipe top, small machinery shall be used for tamping. Each
layer of loose soil shall be 0.25-0.4m in thickness.
(2) Construction machinery
Excvavtors, cutting machine and shovels.
3.2.3 Construction Camp
The gas facilities renovation project is located in Yangcheng County, and the construction
workers are all local staff, no need for setting up construction camps. The two pipe network of
the project will be constructed in sections. The design takes 5km as a section, each section has
a construction period of about 50 days, and there will be no more than 8 people during the
peak construction period. Construction camps use the the nearby village rental housing, the
use of local living facilities, set up canteens, the largest number of people eating in the
canteen will be no more than 8. Clean fuel canned liquefied gas should be selected for the
onstruction personnel canteen, coal is strictly prohibited; Workers will produce some
domestic waste, garbage collection barrels will be set, regularly collected and disposed by the
sanitation department; The hand wash water should be spilled to suppress the dust, other
small amount of living water be collected into the bucket, after precipitation, use the upper
clean water to spray the dust and the bottom dregs be dumped into the trash bin. Construction
workers are recruited local personnel, there is no cultural difference. Through the villages
along the pipe network, drinking water is the same as the local villagers, all of which are in
line with the drinking water standard.
