1.2 Characteristics of This Project Lanzhou–Chongqing Railway goes through, from the north to the south, such three geomorphic units as Loess Plateau, high and medium mountains of the Qinling Mountains and low mountain and hill zone and spans such four climate zones as the arid climate area in the mid-temperate zone of Loess Plateau, sub-humid climate zone of mid-temperate zone, North Asia tropical humid zone in the high and medium mountains in the Qinling Mountains and Middle Asia tropical humid zone in Sichuan Basin. Along Lanzhou-Chongqing Railway, there are many kinds of vegetation. The horizontal and vertical distribution of vegetation is obvious. Roughly, Qinling Mountains is taken as the dividing line. The land erosion area in the drainage area of the Yellow River, in which the railway goes, is big, and the erosion extent is mainly medium, but it is serious or extra serious for some sections. The erosion variety takes the water conservancy erosion as the main and such gravity erosions as mud-stone flow and landslide etc. often occur in the earth and stone and mountain area. The ecological environment along the line sections in the drainage area of the Yangtze River is comparatively better, and, basically no obvious erosion or only light erosion can be seen for soil erosion. Along the line, there are rich resources of wildings as well as cultural relics, which are mainly distributed in the natural reservation zones, the famous scenery spots and historical relics, forest parks, important marshes and the cultural relic protection zones and are greatly affected by the human activities. Ancient Xiaguanying relic, ancient Shannashuzha relic, Yuhe Natural Reserve of Gansu Province, Sichuan Maozhai Natural Reserve, Wetlands Natural Reserve of Jialing River Source, Myxiocyprinus Asiaticus of Natural Reserve, etc.; the target of eco-environmental protection is mainly cultural heritage, the vegetation, rare animal and land resources, etc. along the line. It is the important contents for environment monitoring work to strictly implement the relevant

state laws and regulations, abide by the requirements and replies from the relevant state and local

2 Beijing OASIS Environmental Protection Technology Co., Ltd. Environment Monitoring Report on New Lanzhou-Chongqing Railway Development Project in Year 2011 departments as well as various levels of departments for cultural relics, water conservation, forestry, environmental protection and fishing administration etc. and strictly execute the various measures in the EIA (environmental impact assessment) report during the construction. The big rivers spanned by the railway line are the Yellow River, the Wei River, the Tao River, the Bailong River, the Jialing River, the Fu River and the Qu River etc. Since high roadbeds will be replaced by bridges for this project, there is much bridge construction engineering for the whole line. The land occupation and disposed earth from the sub-grade for non-river-crossing bridges has certain impact on the ecological environment along the line, so has the construction of river-crossing bridges on the water quality and hydro bios of rivers. The total earth and stone workload along this line is large and the volume of disposed earth is far bigger than the volume of taken earth, so it is vitally important to further optimize the allotment of earth and stone cubage, reduce the earth-taking and earth-disposing volumes and occupied land areas, take such preventive measures as land reclamation and afforestation etc. in accordance with the land reclamation program and design for temporary land use and prevent the generation of new land erosion.

1.3 Environment Monitoring The environment monitoring is to supervise and check the implementation status of environment protection measures during the construction period of project on the basis of design and EIA of project, find the existing problems and suggest the solutions. By strengthening process control, the environmental monitoring ensures to carry out "Three-simultaneousness" system strictly. It reflects the dynamic implementation status of environmental protection work on the construction site during the construction activities so as to confirm whether the relevant rules and regulations for environmental protection have been satisfied and whether the requirements from Ministry of Railways and Asian Development Bank have been met. The focuses of environmental monitoring include:  Whether the environmental impacts caused in the construction period are the same as those environmental problems in the EIA report;  Implementation status of environmental protection measures in the EIA report;  Recognize and find the unanticipated environment problems and put forward the solutions; The environmental monitoring of Lanzhou-Chongqing Railway is taken by Beijing OASIS Environmental Protection Technology Co., Ltd. The service range is the main line of Lanzhou-Chongqing Railway from Lanzhou to North Beibei, which is 818.71 Km long in total. The cycle of environment monitoring work is the construction period of the whole line and within the two years after putting into operation after completion. For every half year of the construction period and for every year of the two years after completion, one environmental monitoring report (in both English and Chinese) should be prepared by OASIS Company on the basis of the on-site survey and collected monitored data and submitted to Foreign Capital Center of Ministry of Railways, Lanzhou-Chongqing Railway Co., Ltd., Development Planning Department of the Ministry of Railways and Asian Development Bank. The monitoring report shall include the following contents:  Impacts on the ecological environment imposed by construction of stations, tunnels, bridges and roadbed inside key ecological environmental protection zones such as natural preservation Beijing OASIS Environmental Protection Technology Co., Ltd. 3 Environment Monitoring Report on New Lanzhou-Chongqing Railway Development Project in Year 2011 zones, scenic spots, forest park and ancient cultural relics etc. as well as the recovery and treatment measures;  Impacts of arrangement, protection, reclamation and afforestation measures for the spoil ground on the water and soil conservation facilities, disturbance imposed by construction to vegetation and recovery and treatment measures;  Impacts of tunnel construction on ambient environment and implementation status of protective measures;  Impacts on the surface water body from the bridge construction and the implementation status of preventive measures;  Implementation of preventive measures on subgrade slope and the effects;  Impact and prevention of noise, sewage water, dust and solid waste created in the construction camps, on the pavements, on the temporary engineering sites and in beam construction and storage yards and rail construction bases, and recovery measures of land for temporary use.  Implementation status of various environmental protection measures adopted in the project (including the noise prevention engineering, sewage water treatment and electromagnetism).  Sanitation of construction camps and health propaganda to construction personnel;

Remark

During this investigation, entrance of Hadapu Tunnel, A’wu Inclined Shaft, Xidie Inclined Shaft, and entrance of Zhifang

Tunnel were investigated. All of them used the air-cooled air compressor. The spoil ground at entrance of Hadapu Tunnel firstly built the retaining wall, but the positions of some retaining walls need to be adjusted due to construction of local roads. The domestic garbage tank was built in the camp. After separating, the doemstic garbage is used to fermant for villagers use. The septic tank was built for the toilet which is regularly dug. The environment is clean and tidy. The spoil ground of A’wu Inclined Shaft of Hadapu Tunnel has built retaining wall, and shall pay attention to discarding slag in layers and falling slope; the discarded slag in some sections has overflowed to retaining wall. Pay attention that spoil ground has impact on Investigation Situation neighboring houses, particularly the house safety in rainy season. The drainage ditch on top of Xidie Inclined Shaft Spoil Ground needs to be built and the retaining wall needs to be built for one end of spoil ground.

Total 407 21 204 128 35 5 9556 79 48 181 74 Note: Nanping Tunnel and Hadapu Tunnel respectively have two contractors; but their statistics are only included in one unit.

Each section conducted the serious check for spoil ground in this second half year, redetermined the quantity, location and mileage as per requirements of Lanzhou-Chongqing Railway; according to actual situation, the designed slag amount and land covering of individual spoil ground were adjusted. Up to now, the number of spoil ground under use is 407. In Table 4-19, if 2 contractors jointly excavate the same tunnel, its statistics is only included in one contractor. Left and right line of Xiqinling Tunnel was considered as two tunnels.

4.2.1 Situation of Spoil Ground

4.2.1.1 Basic Data of Spoil Ground

● Proposing of Problems Our compay reconfirmed and calculated the quantity and basic data in environmental protection implementation table reported to us in 2011 by each contractor based on those in their first half year of 2011. Compare the relevant change of spoil ground quantity and basic data reported in June. Have greatly changed the specific name, location, quantity, designed borrowing and discarding quantity and area of land covering in mu, and basic data. The spoil ground is one of the important contents for acceptance of environmental and water protection engineering for Lanzhou-Chongqing Railway; the unclear basic data of spoil grounds will directly affect the supervision and management of Lanzhou-Chongqing Railway in later stage of environmental

Beijing OASIS Environmental Protection Technology Co., Ltd. 71 Environment Monitoring Report on New Lanzhou-Chongqing Railway Development Project in Year 2011 and water protection work, and directly affect the handling of spoil grounds and acceptance of environmental and water protection engineering. ● Measures It is the third year for Lanzhou-Chongqing Railway to construct; the railway construction engineering has been fully conducted and the utilization of spoil ground has been basically developed. During this investigation, we cooperated with Lanzhou-Chongqing Railway Co., Ltd. to conduct the more careful check for the basic data, e.g. each contractor’s used quantity of spoil ground, location of each ground, designed spoil amount and occupied acreage, and examined the utilization and recovery situation of some large-sized spoil grounds at site. The company asks each construction section to report the statistics of borrow pit and spoil ground after unification, careful check and confirming all the basic data to lay basic data statistics carefully for future acceptance. ● Result Through repeated check with each contractor, the basic data of used spoil ground by each contractor has been basically known at present. From Summary Sheet of Main Environmental and Water Protection Engineering for Lanzhou-Chongqing Railway in Table 4-19, the used quantity of spoil grounds along whole line of Lanzhou-Chongqing Railway is 407 up to now. According to designed slag discarding, there are 5 spoil grounds that design to discard slag over (equal to) 100×104m3, 35 spoil grounds between 50×104m3 (excluding) to 100×104m3 (excluding), 128 spoil grounds between 20×104m3 (excluding) to 50×104m3 (including), 225 spoil grounds less than 20×104m3 (including); the total slag discarding is nearly 9556×104m3. ● Residual Problem Table 4-19 basically reflects the present use of spoil ground of Lanzhou-Chongqing Railway engineering; compared with reported data of first half year, the relevant data was supplemented and perfected to some extent. It is known that a few spoil grounds of some bid sections still needs expanding; some spoil grounds have not been used up to now; the data in table of environmental protection implementation situation is incomplete due to non-arrival of design drawing, etc., some short of designed soil discarding and some short of occupied acreage, so Lanzhou-Chongqing Railway Co., Ltd. will continue to check and adjust the basic data of spoil grounds. 4.2.1.2 Field Investigation of Spoil Grounds From this investigation, we stressed to investigate the recovery situation of large-sized spoil grounds for each contractor. During this environment monitoring investigation, we visited 18 contractors of 15 sections along whole line of Lanzhou-Chongqing Railway and checked 23 spoil grounds at site, including: Spoil ground of Dongdu Road Inclined Shaft of Humaling Tunnel, spoil ground at exit of Kezhai Tunnel, spoil ground of Daping Inclined Shaft without rail and that with rail of Muzhailing Tunnel, spoil ground of Nanshuigou Inclined Shaft and spoil ground of Dazhangou Inclined Shaft, spoil ground at entrance of Hadapu Tunnel, spoil ground of A’wu Inclined Shaft and spoil ground of Xidie Inclined Shaft, spoil ground at entrance of Zhifang Tunnel, spoil ground at Tianchiligou Inclined Shaft of Tianchiping Tunnel, spoil ground of Guangpinggou Inclined Shaft, No. 1 and 2 spoil ground at entrance of Luosha Tunnel, spoil ground at entrance of
