(Part III: Pipeline Project from Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 8 guo huan ping zheng jia zi No.1303 (3) Trying to avoid the town planning area, development area, industrial and mining area as well as cash crops area such as fruit trees area, vegetables area, plastic tents area, etc. and important farm capital construction facilities of the cities and counties along the pipeline. (4) Trying to base on and utilize the existing roads to facilitate pipe transportation, construction and production & maintenance management. 2.3.2 Safety Spacing of Pipes The routes should be selected on the basis of area grade division pursuant to Town Gas Design Code . The routing of pipelines in this project mainly covers Grade I and Grade II areas as well as a small Grade III area. The horizontal clear distance between pipeline and buildings or structures or between neighboring pipelines should strictly comply with the requirements pursuant to GB50028 Town Gas Design Code . 2.3.3 Pipeline Laying In view of the landform, geomorphology, engineering geology, hydrogeology, climatic conditions, etc., the method of ditch excavation and direct laying will be adopted in this project for general locations. The depth of covering earth up the pipe is 1.0-1.2m. The pipeline crosses 1 highway, and the crossing length is 10m. It also crosses 1 river, and the crossing length is 120m. Ditch will be excavated to lay and bury the pipes directly in the river, and the ditch depth is not less than 1.0m from the outer covering layer of the pipe to the eroding line, and it should be guaranteed that the minimum covering earth of the pipeline shall not be less than 2m; if there is no eroding data about the crossed river, it should be guaranteed that the pipeline should be buried not less than 2m below the riverbed earth. The banks on both sides of the river or canal should be protected with the method of rubble slope protection. 2.3.4 Pipeline Crossing Works 2.3.4.1 Crossing River This project crosses Guxian River. The river is basically an ephemeral stream, with a small flow in normal times except the flood season. The pipeline crosses the river once, and the crossing length is 120m.

(Part III: Pipeline Project from Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 9 guo huan ping zheng jia zi No.1303 The form of river diversion by cofferdam and ditch excavation for burying and laying pipes will be adopted at river crossing site. The pipeline will be buried under the stable earth layer of the river bed and bank slope, the depth of pipe covering earth under the stable earth layer is preliminarily defined as not less than 2m. Concrete balancing weight is used to stabilize the pipes in excavation of river-crossing ditch. The balancing weight will be evenly distributed along the whole crossing pipeline. 2.3.4.2 Crossing Highway This project crosses Grade II highway once, and pipe jacking crossing method will be used. The crossing method of ditch excavation and direct burial will be used in crossing township highway. 2.3.4.3 Crossing Other Underground Pipeline and Cable When the pipeline crosses other various types of pipelines, it should cross them from underneath in principle, and the clear distance between them should not be less than 0.3m. When the pipeline crosses various types of cables, it must cross them from underneath, and the clear distance between them should not be less than 0.5m. Protective measures should be taken during construction. 2.3.5 Main Pipes See Table 2-3-1 for the main pipes.

Environmental Impact Assessment and Mitigation Measures 4.1. Environmental Impact Assessment and Mitigation Measures during Construction Period During the project construction period, the component with great impact upon the environment is mainly the laying of gas pipeline; the transportation and stacking of construction materials in the course of construction may also exert certain impact upon the ambient air, the ambient sound and ecological environment. When the construction is completed, its impact will no longer occur, and its impact upon local ecological environment will also be removed gradually. 4.1.1 Analysis of Impact upon Ecological Environmental 4.1.1.1 Analysis of Impact upon Natural Ecology (1) Analysis of Impact upon Ecological Components and Bio-diversity It is learned from survey on the status quo of the eco-environment along the proposed gas pipeline, the bio-communities within the area along the pipeline mainly consist of common species and dispersed species (Bothriochloa ischaemum, green foxtail, salsola, Artemisia lavandulaefolia, Artemisia stolonifera, Artemisia annua, etc.). Of the different periods of gas pipeline construction, the construction period has the greatest impact the eco-environment, but the adverse impact is temporary. This is mainly represented by the obvious damage to the surface vegetation and water system on the construction site during earth surface excavation and dumped waste material along the river, and the temporary sites such as earth taking and dumping sites along the pipeline and the construction site also have the problem of disrupting the eco- environment. (2) Analysis of Impact upon Ecological Pattern Analyzed from the utilization state of the land along the proposed gas pipeline, the assessment area mainly consists of farmland and wasteland. Farmland is the background matrix constituting the structure of the landscape along the pipeline and at the same time determines the basic function and dynamic trend of the landscape. The construction design requires construction of new roads or utilization of the existing roads as access roads for construction; in the road section under construction, Page 12 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 12 guo huan ping zheng jia zi No.1303 farmland water conservancy facilities will also be tied up and agricultural traffic will be affected. Therefore, the construction period has a large impact upon the agro- production pattern, and such impact will be very obvious especially in the directly affected area. In view of this, taking such measures as restoration of vegetation and farmland rehabilitation for temporary land occupation, taking necessary temporary emergency measures for irrigation and agricultural traffic and implementing such measures in the whole process of construction are the essential way of mitigating or avoiding the adverse impact upon the ecological pattern along the pipeline. (3) Analysis of Impact upon Ecosystem Functions The basic function of eco-system is conversion of substance and fixation of energy, specifically represented by production function, regulation function, protection function, etc. of eco-system. The most important production function of the ecosystem in the area along the pipeline is agro-production function. On the condition of taking necessary temporary measures and strengthening management during the construction period, no obvious impact will be exerted on the agricultural pattern and components, i.e., no adverse impact will be exerted on the agro-ecological structure. As the ecological functions are subject to the structure of ecosystem, no obvious adverse impact will be exerted on the agro-production function of the area along the pipeline. The proposed pipeline project will occupy a land area of 0.57hm 2 on a temporary basis, of which, the area of farmland is 0.2hm 2 , and the area of low coverage grassland is 0.37hm 2 . This project will have impact on the wasteland (mainly low coverage grassland) and farmland. The vegetation biomass loss caused by project land occupation is calculated according to the following equation. See Table 4-1-2 for the results of calculation. Closs= å × Si Qi In the equation, C loss – value of total biomass loss, kg; Qi – yielding capacity of the i th species of vegetation organism, kg / mu; Si – land area of the i th species of vegetation occupied, mu. Table 4-1-2: Table of Estimated Vegetation Biomass Loss Caused by Land Page 13 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 13 guo huan ping zheng jia zi No.1303 Occupation of Proposed Project Type of vegetation Covered land area (hm 2 Unit area biomass g/m 2 ·a Amount of loss t Farmland 0.2 650 1.30 L ow coverage grassland 0.37 500 1.85 Total 0.57 — 3.15 It can be seen from the above table that the vegetation biomass loss caused by the land occupation of the proposed project is about 3.15t/a, of which, the biomass loss caused by occupation of farmland and wasteland is 1.30t and 1.85t respectively. The regulation and protection function of the ecosystem in this area is determined by the natural vegetation conditions in this area, and the impact exerted during the construction period is evidently greater than that during the operation period. (4) Analysis of Impact upon Eco-environment along the Pipeline The pipeline of this project has a total length of 1434m. The impact of pipeline construction on the eco-environment is mainly represented by damage to original vegetation, soil perturbation, impact on the habitat of wild animals and soil organisms, etc., caused by temporary land occupation of the project. In the course of construction, efforts should be made to minimize damage to the vegetation surrounding the pipeline, reduce rolling compaction of mechanical transportation and perturbation of a certain degree on the construction site and its surrounding vegetation caused by trampling of construction workers. Proactive and effective measures should be taken to minimize the impact of the project upon the local ecological environment and protect and utilize the original trees and shrubs. The principle of “proper trees at proper places” should be insisted on to conduct vegetation planting and greening project scientifically, select plant species suitable for planting based on the planting conditions and pay attention to collocation of grass, shrub, arbor species and combination of short-, medium- and long-term benefits. Bio-measures and engineering measures should be combined based on local conditions, to make the forestation and greening applicable, cost-cost-effective and attractive and make them play the role of protecting and beautifying the environment. The implementation of the above measures during the different periods of construction along the pipeline can not only eliminate or minimize the adverse impact Page 14 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 14 guo huan ping zheng jia zi No.1303 of project construction upon the eco-environment but also improve the eco- environment of the project area and its surrounding area. (5) Analysis of Impact of Construction Access Road upon Eco-environment The construction access roads of this project, roughly along the existing roads, have a short mileage and their land occupation is little and temporary. After the completion of the project, all the land can be reclaimed, and therefore, the land occupation of construction access roads has a relatively small impact upon agro-production. 4.1.2.1 Analysis of Impact upon Agricultural Ecology [1] Statistics of Land Requisition of the Proposed Project The total land and vegetation area occupied by the pipeline project is 0.57hm 2 , of which, the farmland area is 0.2hm 2 , so project construction has a considerable impact upon the farmland eco-system. [2] Analysis of Impact of Project Land Occupation upon Agricultural Eco- environment The impact of temporary land occupation of this project upon the local agricultural eco-environment is temporary. In view of the actual conditions of agro-production in the area along the pipeline, attention should be paid to the following issues in the process of project construction: (1) The land occupation of the proposed pipeline does not exert much impact upon the agro-production along the pipeline in terms of gross impact upon the affected area, but a good job should still be done in compensation for land requisition and the compensation funds should be made available according to relevant standards. (2) Attention should be paid to rehabilitation of the temporarily occupied production land and efforts should be made to restore such land into farmland, woodland and garden plot based on the characteristics of the surrounding environment to reduce the loss caused by land occupation of the project. (3) The farmland loss is assumed by the individual townships and residents along the pipeline, but such impact upon individual residents or small collectives is temporary. However, this project construction should minimize farmland occupation and reduce impact upon the local agricultural eco-environment. (4) The construction site of the proposed pipeline should be greened in time to compensate for the impact of this project on the local forestry eco-environment.

(Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 15 guo huan ping zheng jia zi No.1303 [3] Economic Loss Estimates of Impact upon Agriculture The impact of construction of the pipeline and the liquification plant upon agro- production can be divided into indirect impact and direct impact. The indirect impact of pipeline construction may play a positive role of promoting economic development, but it is difficult to estimate the degree of its impact; its direct impact may be measured by estimating loss in agro- and forestry production through calculation of reduction in production area. Direct economic loss may be estimated according to the following formula: Economic loss = reduced production area × unit area yield × unit market price = unit market price × reduced production area × total yield / total production area = production area loss rate × total yield × unit market price = production area loss rate × total yield value Agricultural loss caused by land occupation of the pipeline project is temporary and it is proposed to estimate the loss on the basis of 3 years (two-year rehabilitation period and 1-year construction period). The agricultural and forestry economic losses caused by project land occupation is estimated by application of the above direction economic loss estimation formula and on the basis of the land utilization status quo of the assessment area in 2006, statistics of project land occupation and the unit area output value of various types of land in the assessment area. See Table 4-1-3 for the results of estimates. Table 4-1-3: Estimates if Impact upon Rural Economy of the Area along the Pipeline Unit area Yearly economic loss Item Occupied area (hm 2 ) Yearly output value (yuan /mu) (in RMB10,000) Temporary land occupation 0.2 16380 0.33 It can be seen from the estimation results that the economic loss caused by temporary land occupation of the project to the assessment area along the pipeline is about RMB3,300; the economic loss caused by temporary land occupation is about Page 16 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 16 guo huan ping zheng jia zi No.1303 RMB10,000 for three years (1 year for construction and 2 years for reclamation and rehabilitation). 4.1.2 Analysis of Impact upon Ambient Air and Mitigation Measures The impact upon ambient air during the construction period is mainly represented by: impact of construction dust emission and secondary dust emission on the environment; damage by pipe laying to the surface vegetation and farmland along the pipeline and exposure of surface soil, which will cause dust emissions upon wind blowing; secondary dust emissions caused by dust-producing construction materials such as sand, cement and lime if they are piled up at random and without any shield. The construction will increase TSP concentration in the ambient air in partial area. Mitigation measures: such measures as covering and sprinkling and dust damping should be adopted during windy season to reduce dust emissions. 4.1.3 Analysis of Impact upon Water Environment and Mitigation Measures (1) Analysis of Impact of Construction Form on the Water Environment The form of river diversion by cofferdam and ditch excavation for burying and laying pipes will be adopted in the project for crossing river, and the construction work should generally be done in low water season. The pipeline will be buried under the stable earth layer of the river bed and bank slope, the depth of pipe covering earth under the stable earth layer is preliminarily defined as not less than 2m. Concrete balancing weight is used to stabilize the pipes in excavation of river-crossing ditch. The balancing weight will be evenly distributed along the whole crossing pipeline. The river-crossing operation of the pipeline would exert short-term impact upon the water quality of the river and the sediment charge in water would increase; improper disposal of surplus earth and stone work after ditch backfilling may cause silting-up of river channel and soil erosion; the operation of river diversion by cofferdam may exert certain impact upon aquatic organism and may even exert certain impact upon the surrounding environment and cause soil erosion or block the river channel if handled improperly. It is suggested in the EIA that the surplus earth and stone work Page 17 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 17 guo huan ping zheng jia zi No.1303 be handled or piled up properly on suitable sites nearby. As long as management is strengthened and effective water and soil conservancy measures are adopted, the construction will not exert much impact upon the river. In short, proper operation schemes should be adopted in such construction activities as ditch excavation and crossing in the river channel so as to minimize the possible impact upon the surface water environment. The above construction activities may exert certain impact upon SS, PH, and petroleum in the water, but the impact is short- lived and will disappear automatically with the completion of the construction. In addition, the relevant stipulations in Shanxi Provincial River Channel Management Regulations should be implemented strictly. Efforts should be made to avoid damaging the existing hydrotechnical safety facilities such as dyke and violating other requirements. (2) Impact of Construction Materials Transportation and Piling upon the Water Body Environment The dust emissions caused by transportation of construction materials and the fine dust caused by construction will exert certain impact upon the surface water body. In addition, some construction materials such asphalt, oil, chemicals, if they are not kept properly at their piling places and are brought into water body by rain wash, will cause pollution to the water environment. In the construction, therefore, protection and management measures should be strengthened according to the characteristics of different construction materials to minimize their impact upon the water environment. (3) Impact of Domestic Sewage from Camp Buildings upon Water Environment The water pollution sources during the construction period of this project is mainly domestic sewage of construction workers, and the major pollutants in the sewage include BOD, SS and COD. The domestic sewage of construction workers is used for road sprinkling and dust damping; as it has small discharge volume and is not discharged into surface water body, it has very little impact upon the surface water body.

(Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 18 guo huan ping zheng jia zi No.1303 4.1.4 Analysis of Noise Impact and Mitigation Measures The main sources of noise during the construction period include noise of various types of mechanical equipment on the construction site and traffic noise caused by transportation of materials. The construction period of this part of the project is earthwork operation period, and the large scale equipment used mainly includes excavator, crane, etc. As the construction period generally involves outdoor work, the noise produced by these construction machines will exert certain impact upon the ambient sound environment. The noise level of various types of construction equipment during the construction process is between 85-100dB(A). The sound levels of noise source at different distances on the construction site are provided based on comparison with the actual situation of other construction sites. See Table 4-1-4. Table 4-1-4: Noise Level of Main Noise Sources at Different Distances during the Construction Period (unit: dB(A)) Noise level at different distance Cons tructi on perio d Main noise source Sound level at sound source 40m 60m 80m 100m 200m 400m Earth and stone work Bulldozer, excavator and transportation vehicles 92 102 60 72 56 66 54 64 52 62 46 56 40 50 foun datio n Pile driver 112 12 2 80 90 76 86 74 84 72 82 66 76 60 70 Concrete mixer 92 102 60 70 56 66 54 64 52 62 46 56 40 50 Struc ture Concrete vibratory machine 87 97 55 65 51 61 59 69 47 57 41 51 35 45 Instal lation Welder, electric drill, electric hammer and multipurpose carpenter’s plane 77 87 45 51 41 51 39 49 37 47 31 41 25 35 Page 19 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 19 guo huan ping zheng jia zi No.1303 In accordance with the stipulations of Limits on Noise at Boundary of Construction Sites , the noise limit at boundary of the construction site is 70-75dB(A) during daytime and 55dB(A) at night. At the foundation stage, night operation of pile driver is prohibited. It can be seen from the above table that the impact distance is within about 60m during daytime and the impact distance except for pile driver is about 210m at night. Therefore, the boundary of construction site of this project can meet the requirements of noise limit standards at boundary of construction sites. Construction near Jinfeng Section at night would affect the normal rest of residents. Mitigation measures: Construction near Jinfeng Section is prohibited at night. 4.1.5 Analysis of Impact of Solid Wastes upon the Environment and Mitigation Measures The pipeline of this project has a total length of 1434m, and the dumped earthwork of the pipeline project is about 0.2m 3 /m. The waste earthwork produced by the pipeline project is used to fill in the low-lying area around the pipeline and then grass seeds will be planted to restore the vegetation and prevent soil erosion. Domestic garbage will be collected, centralized and transported to Duanshi Town Domestic Garbage Disposal Plant for disposal. 4.2 Analysis of Impact on Environment and Mitigation Measures during Operation Period 4.2.1 Analysis of Impact on Ecological Environment and Mitigation Measures At normal operation state, the area where pipelines are laid is under normal conditions, surface vegetation and farm crops growing are normal, animal corridor cut by the project during construction period is restored as well. According to the data, the first gas transmission pipeline in Northern China has been running for more than 20 years, no unhealthy tendency is discovered about the surface natural ecological environment and agricultural eco-environment in the area with CBM pipelines laid underground, surface vegetation and farm crops growing in the area with pipelines laid underground make no obvious difference from the area without that, which is a proof that pipeline transmission is a clean transmission mode with slightest impact on Page 20 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd. (Part Pipeline Project from the Central Gas Treatment Station to LNG Plant) Coal Industry Taiyuan Design & Research Institute 20 guo huan ping zheng jia zi No.1303 ecological environment and smallest scope of impact. Therefore, it can be considered that pipeline produces no unfavorable influence on ecological environment during the regular gas transmission process. 4.2.2 Analysis of Impact on Water Environment and Mitigation Measures No pollutants such as effluent will be discharged during pipeline operation period. It is a clean transmission mode and produces no impact on water environment. 4.2.3 Analysis of Impact on Ambient Sound and Mitigation Measures No noise will be produced during pipeline operation period and no impact will be exerted upon ambient sound. 4.2.4 Analysis of Impact on Ambient Air and Mitigation Measures No gas emissions will be produced during pipeline operation period and no impact will be exerted on ambient air. 4.2.5 Analysis of Impact of Solid Wastes on Environment and Mitigation Measures No solid wastes will be produced during pipeline operation period and no impact will be exerted on environment. 4.3 Analysis and Assessment of Environmental Impact during Servicing / Maintenance Period The main environmental impact during servicing / maintenance period lies in sludge produced during pigging operation (with ferric oxide as principle component). Ferric oxide is a general industrial solid waste, and the volume of sludge produced in the project is about 2kg, which is to be transported by Environment and Sanitation Page 21 EIA Report of Proposed WB Financing CBM Development and Utilization Demonstration Project of Shanxi Energy CBM Investment Controlling Co., Ltd.
