Various local environmental protection bureaus along the line take charge of environmental protection supervision and management in areas under their respective jurisdiction. Environment monitoring for Yi-Wan Railway is undertaken by Beijing OASIS Environment Protection Technology Co., Ltd. The construction and supervision units are responsible for daily monitoring and supervision during construction period. The implementation unit and OASIS are responsible to collect monitoring data, and then OASIS shall compile the environment monitoring report and submit it to the MOR and Asian Development Bank. The monitoring unit has, upon the requirements set forth in the monitoring contract, prepared the block diagram of environment monitoring procedures for Yi-Wan Railway (see Figure 3-1).

According to the characteristics of this project and environmental issues often occurring in construction period, the monitoring unit is required to formulate the environmental protection rules in the following aspects: ● The construction and supervision units shall employ full-time (part-time) environmental protection personnel. All full-time (part-time) environmental protection personnel should accept special training on environmental protection, as well as be responsible to supervise and treat with various environmental issues arising in production under their own responsibility, and assist environmental management departments to manage environmental protection. ● Ask various construction units to perform related environmental protection statements in the construction contract. The construction units are also required to work out appropriate environmental protection measures according to environmental protection requirements set forth in the design documents, so as to protect the environment of construction site, as well as to avoid and reduce pollution and ruin of the environment due to inappropriate construction means. Once any event to destroy the environment happens, they should actively take remedies. If they cannot solve such issues by themselves, they should immediately invite appropriate experts and organizations to assist them to solve the problems. ● Ask environmental supervision units to perform daily environmental supervision upon the environmental protection requirements set forth in the construction contract. Once any environmental issues occur in construction, the supervision units should urge the construction units to solve them in time.

3.2 Environmental Management during Construction Period in First Half of 2009

3.2.1 Advanced Flood Arrangement of Yi-Wan Railway Headquarters for 2009 On April 7, 2009, Yi-Wan Railway Headquarters issued the Notice on Careful Flood Arrangement in 2009, the Notice states 6 requirements for carrying out flood responsibility in all-around manner, organizing flood safety examination, clarifying the key points and appointing specific staff for watching, further intensifying the contingency schemes, setting the watching system in flood season and requiring supervisors to conduct self-examination carefully. The Safety & Quality Division of Yi-Wan Railway Headquarter organized the relevant supervisors and constructors to conduct the inspection on the flood arrangement and the safety and quality of the station facilities under construction from May 4 to 15, 2009. The inspection covers 31 bid segments and 8 station facilities under construction, 19 copies of routine inspection records have been filled up in response to the problems found in the inspection, and the inspectors have exchanged opinions with the relevant units on the spot and put forward the requirements for rectification and improvement. The supervision stations are required to urge the rectification and improvement and the recheck. Particularly, there are five tunnels with first-grade risk of sudden mud and water flows in the flood season, the inspectors put forward the specific requirements such as intensifying on-the-spot duty and hydrological observation to prevent against accidents. 3.2.2 Supervision of China Railway 4th Bureau During the Inspection, the company received 3 copies of monthly reports of the supervision station of China Railway 4th Bureau on supervision during February to April 2009 and 7 copies of reports on hydrological supervision on the five key tunnels during the first half year of 2009. In accordance with the monthly supervision reports, the supervisor of China Railway 4th Bureau Station conducts 30 -35 construction segments in each month, watch 100 soil collecting and piling sites, spoil piling sites, bridges, stations and sub-grades, etc. records authentically the state and changes of the construction sites, while appreciating their achievements, the inspectors also indicates the problems that need to be corrected and the possible hidden disasters, and issues the notification on the rectification and improvement for the key problems. The monthly supervision reports submitted to Yi-Wan Railway Headquarters play a significant role for the Headquarters in learning the schedule of environmental and water protection along the entire side in time and timely making decision and supervising the key problems. For example, the environmental supervision project division of China Railway 4th Bureau suggested that the Headquarters “arrange in advance the inspection during the flood season in 2009 before the flood season” in the monthly supervision report submitted in February 2009; On May 12, 2009 or so, there was a strong precipitation along the line between Hubei and Chongqing, and the maximum precipitation around Lichuan reached 120mm, which lead to flood disaster in some areas in Hubei and Chongqing to different extents. To our gratification, the spoil sites along Yi-Wan Railway withstood the challenge of the strong flood without collapse accident due to the concerns and strict requirements of Yi-Wan Railway Headquarters, the routine inspection and urgency of the supervision stations and segments and the long-term efforts of the constructors. 3.2.3 Supervision on Water and Soil Conservation In accordance with the contract, Changjiang Water Resources Commission and Changjiang

4.2 Brief Summary

The construction for Yi-Wan Railway has come to an end. The tunnels, bridges and sub-grades projects relating to the railway have been completed in generally except for Qiyueshan Tunnel, Yesanguan Tunnel, Dazhiping Tunnel, of which, the construction progresses slowly due to their complex geological conditions and remarkable hidden accidents. The follow-up projects have been launched in all-around manner. As Yi-Wan Railway locates within the mountainous area, there are many tunnels and bridges need to be built, those tunnels and bridges account for over 70% of the entire line. The construction for those tunnels and bridges produce a lot of spoil, which will lead to water and soil loss if disposed inappropriately, and the drainage channels will be affected in the flood season. The full renewal and safe shield of the soil collecting/piling sites and the spoil/soil sites are the significant ite4ms in the environment and water protection for Yi-Wan Railway construction. The investigation showed that the constructors attached great importance to the renewal of those spoil sites in the late construction period, the constructors who have completed their construction have centralized personal and material powers and put them in the renewal work of the spoil sites in the late construction period late as required by flood prevention of Yi-Wan Railway Headquarters. The key spoil sites concerned by the letter of ADB and the problems put forward by OASSIS company’s last report have been remarkably improved. The details are as follows:

4.2.1 Spoil Sites between No. 35 Bid and No. 42 bid within Wangzhou Segment of Yi-Wan Line have been Handed over to Local Authorities The construction for Wangzhou segment between No. 35 Bid and No. 42 Bid of Yi-Wan Railway has been completed totally. Since December 12, 2008, the constructors have compiled the related documents on acquirement and preliminary design for 31 spoil sites in detail as required and submitted those documents to the local competent authorities of environmental protection, water conservation and land as well as local railway offices and local development and reform committees for approval, and the project had been jointly examined and inspected by the local competent authorities. Yi-Wan Railway Headquarters has officially handled the handover formalities with the local competent authorities in Wanzhou District in May 2009. Picture 6: Spoil site at the entrance to Tiziyan Tunnel (ladder tunnel) constructed by China Railway 1st Bureau in No. 36 Bid; Picture 7: Spoil site at the entrance to Miaowan Tunnel constructed by China Railway 11th Bureau in Bid 40; Picture 8: Spoil site at the exit of Bieyancao Tunnel constructed by China Railway 20th Bureau in Bid 37 4.2.2. The Situation of Key Spoil Sites On March 6, 2009, we have received a letter from ABD, in which, ADB stated their concerns on

Beijing OASIS Environment Protection Technology Co., Ltd. 57

2009 Interim Environment Monitoring Report of Yichang-Wanzhou Railway the spoil site at the entrance to Yanwan 2# Tunnel, Kongzidong Site and the spoil site at the exit of Qiyueshan Tunnel. We had conducted an investigation on the relevant spoil sites and the construction thereof by combining the problems we put forward in the former reports. The investment covers an examination for all spoil sites of the tunnels that under strict control except for the condition the construction sidewalk was jammed due to raining. The details are as follows: -Spoil site at the entrance of Yanwan No. 2Tunnel The spoil dumped in the site at the entrance to Yanwan No. 2 Tunnel in Bid 5 is about 190,000m3, as the site locates in the valley, the spoil piled reach 50-60m high with steep slopes, and therefore, it is more difficult to renew the site. To accomplish the site renewal in the high-quality manner, China Railway 3rd Bureau employed the high-grade local excavator technicians in Yichang to laminate, descend and level the site, and the drainage ditches have been built on the surface of the area with steep slope in accordance with the design requirement. At present, new land are acquired for the site at the entrance to Yanwan No. 2 Tunnel to reinforce the retaining walls. For the time being, the renewing of the spoil site has been completed in general, and the local competent authority express their satisfaction with the renewing quality of the site and agreed to accept the site. Picture 9: The renewed spoil site at the entrance to Yan Wan No. 2 Tunnel -Spoil site at Kongzidong Tunnel The site is located on a hillside at Langping Town. The site is adjacent to the village roads and residential area, the designed volume of the spoil is 83,000 m3. The retaining walls of the drainage ditches on the hillside at the foot of the spoil pile have been completed and the walls are more than 20m higher than the pile. To ensure the life and safety of the mass in Langping town, Yi-Wan Railway Headquarters has issued the notice of rectification and improvement at the beginning of 2008, asking China Railway 14th Bureau to descend the pile and transport the spoil out. The investigation showed China Railway 14th has earnestly carried out the requirements of the Headquarters and adopted the following measures: -Transport the spoil to Tieluoping Spoil Site. At present, about 2/3 spoil is transported; - Require the designer, Changyang Hydrological Reconnaissance Institute to modify the design (the modified design shall be approved by the Headquarters). At present, the spoil transport is stopped, and the retaining walls are heightened according to the modified design, the remaining spoil is laminated, descended and leveled. Picture 10: Kongzidong Spoil Site is being renewed according to the modified design. - Qiyueshan Tunnel There are 233 m of tunnel unexcavated on the main line of Qiyueshan Tunnel and the 163 m of horizontal guider line left; F11 Fault lasts 210 m at the middle of the tunnel, which accommodates large volume of water inside, with the maximum water pressure of 2.7MPa approx. At present, the fault is the key section of the entire project. The spoil dumping in the site at the entrance to Qiyueshan Tunnel in Bid 32 has been completed;

Beijing OASIS Environment Protection Technology Co., Ltd. 58

2009 Interim Environment Monitoring Report of Yichang-Wanzhou Railway there are anti-skid piles foundation at the site, now the spoil is utilized by the mass, the total spoil at the site has been reduced by 1/3; as there are farms at one side of the site, the spoil site continues to shrink inward and needs to built retaining walls in the end. In accordance with the report issued by Lichuan municipal environmental supervision station on hydrological supervision during January to March, the following information is obtained: Supervision item: PH value, water temperature, COD, BOD, DO, C16+，oils, SS, ammonia and nitrogen, and sulfides. Sampling site: 1# - General drainage port of the tunnel, the drained water is required to reach the Grade-I Standard of Sewage Comprehensive Discharge Standard. 2# - At the position 70 m lower than the general drainage port, and the water is required to the Grade III Standard of Surface Water Environment Quality Standard. 3# - At the position 300m above the general drainage port. Conclusion: All parameters of the samples reach the standards concerned except for SS in the water sampled at 1# position in February and March. Since December 2008, the constructor of Qiyueshan Tunnel in Bid 33 has been changed and China Railway 12th Bureau replaced the 15th Bureau to construct the tunnel, however, the responsibility for renewing the spoil site has not been determined up to now. Therefore, the problems existing in the spoil site at the exit of Qiyunshan Tunnel have not been corrected. We have asked Yi-Wan Railway Headquarters to clarify the responsibility for renewing the site so that the responsible party may be aware the existing problems and solve them in time. - Slurry Pool at Juanqiaohe Bridge The slurry pool of Juanqiaohe Bridge in Bid 33 (at left side of DK22+300), locates in the valley, and it has accommodated about 30,000 m3 of slurry that is generated during the construction for Juanqiaohe Bridge. It occupies 15 mu land and is 3 m deep. Since it was put in use in 2006, the slurry cannot be dried, which became a trap for people and livestock. Yi-Wan Railway Headquarters, China Railway Engineering General Corp. and China Railway 4th Bureau have attached great importance to the pool. During construction, the project headquarters, besides building dams, ditches and retaining walls, have set warning board, wire grid around the slurry pool to prevent against the accidental personal injury during the construction period. For the time being, the construction has been completed, the investigation showed that there is no water accumulated on the surface of the slurry pool, where grows 2m-high plants. The investigators and the Headquarters staff entered in the slurry pool for about 10 m long and found that the area around the slurry pool can withstand the weight of persons. At present, the constructor is handling handover formalities with the local authority, we hereby suggest they do well in the handover handling on the basis that the safety of the central area of the pool is confirmed.

- Spoil site at the first line of Baiyunshan Tunnel There are farms around the spoil site at the first line of Baiyunshan Tunnel in Bid 6, and only part of grade-six retaining wall at the farm side has been completed by the end of 2008. The investigation showed that the retaining walls for the spoil site at the first line of Baiyunshan Tunnel have been completed entirely (refer to Picture 12) - Spoil site of the transverse tunnel of Wuzhaoguan Tunnel The spoil site of the transverse tunnel of Wuzhaoguan Tunnel in Bid 7 occupies 49.6 mu of land and accommodates 190,000 m3 of spoil. The retaining walls, drainage ditches and the spoil site have been renewed in place, but not been covered with soil for virescence or second plowing. (see Picture 13). - Spoil site 1# at the entrance to Baozhen Tunnel The spoil site 1# at the entrance to Baozhen Tunnel is designed to occupy 121.5 mu, and the actual volume of spoil at the site is 788,000 m3. Therefore, it is very difficult to renew the site as it covers a large land and accommodates huge spoil. The secretary of China Railway 14th Bureau who is responsible for environmental protection takes charge of the renewing work and often makes direction and submersion on the spot in person. The investigation showed that the spoil site is renewed with high-quality, and the local farmers have planted wheat on the surface of the site.(See picture 14) - Spoil site of the second line at the entrance to Yesanguan Tunnel The spoil site of the second line at the entrance to Yesanguan Tunnel occupies a land of 65.4 mu and accommodates 430,000 m3 (of which, 280,000 m3 of gravels and sand have been processed). The retaining wall at the entrance to the ditch has been completed, and the wall has been reinforced with the cement framework for the slopes at both sides and planted with grass; and the side wall of the ditch along the village road has been completed, the spoil at the site has been laminated, too; The culvert was specially built for the water drained from the mountain; the surface of the site needs to be further leveled and greened. (Refer to Picture 15). - Wujiawan Spoil Site Wujiawan spoil site in Bid 17 occupies 122mu of land and accommodates 750,000 m3. The spoil site locates in a narrow valley outside of the transverse tunnel, and the retaining walls thereof have been completed. The surface of the site is leveled in general, but the drainage ditch has not been built yet. In short, the spit needs to be further leveled and greened. (See picture 16). The investigation showed that the spoil sites along Yi-Wan Line have been renewed or are being renewed except for those handed over to the local authorities. The renewing work is not very difficult and there is no serious hidden disaster found. The spoil at the area around Qingyangou in Bid 10 has been randomly dumped for years (by many units), but now, such phenomenon has been changed greatly, however, further efforts shall be made to solve the problem.

Picture 20: Part of retaining walls and drainage ditches of the spoil site of the oblique shaft of Jinzishan Tunnel in Bid 28 has been completed but the site is not renewed in place yet. - Spoil site of Malujing Tunnel The spoil sites at the entrances to Baiyunshan Tunnel, Yesanguan Tunnel and Malujing Tunnel have not been investigated on the spot in this investigation due to the raining that led inconvenience to vehicles on the construction sidewalk. However, as far as our knowledge, the spoil site at the entrance to Malujing Tunnel sustained the influence of accidental flood on April 11 and 19, and 300,000 m3 of spoil have been carried in Dukouhe River at the lower reach and 185,000 m3 have been deposited in Changyang ditch and need to be cleared away. As the cleaning workload for the spoil carried in the river-way is very large and difficult, the work stresses shall be focused on such work in the future. 4.2.3. Suggestions The spoil site at the entrance to Yanwan No.2 Tunnel in Bid 5 has been renewed in place generally. Yi-Wan Railway Headquarters and China Railway 3rd Bureau have attached great importance to the site and made great efforts, it is not easy to renew the site to the extent at present. However, as said by the environmental supervision station of China Railway 4th Bureau, the site features steep slopes and a high spoil pile, it is a close watch item to see whether the drainage ditches built at present can be maintained stably in the flood season without broken or sink. The units concerned shall, instead of letting down their guard, continue to observe the trend of the spoil site and make the record where necessary. 4.2.4.

2. Conclusions on Monitoring during January to June 2009 (1) Qiyueshan Tunnel Entrance Segment In accordance of the current monitoring data, the drainage at the entrance to Qiyueshan Tunnel is controlled within the designed range, there is no obvious evidence that indicates the influence of the tunnel drainage to the water volumes of the big and small Yuquan, the plants on the hill grows well and the water level of the monitoring points are stable without sharp decrease or disappear, which show the pressure of the water system is maintained at the higher level, and the tunnel drainage has not cause the disappearing of the water level at the monitoring points due to the huge leakage of the ground water. For the time being, the tunnel is still under construction, and the construction enters to the most difficult stage as there is richest groundwater. The tunnels has been constructed with the technology of curtain grouting and sealing batholite, and the tunnel drainage decreases comparing with that in the past, however, the influence of the tunnel drainage shall be observed continuously. For the time being, there is no serious influence of tunnel construction to the environment found. Exit Segment During the construction in the this season, the technology of curtain grouting and sealing botholite has been adopted for construction of the tunnel, such construction has a remarkable effect of water decreasing, therefore, there is no great fluctuation in the tunnel drainage, according to the analysis on the data of the monitoring points, there is no abnormality happened. Up to now, there is no great influence of tunnel construction to the environment found. As the tunnel is under construction now, it is necessary to make the further monitoring over the influence extent of the tunnel construction to the environment. (2) Wuzhaoguan Tunnel The construction for tunnels along Line I and II have been completed, and the continuity of the ground river has not sustained any damage, the water system is smooth and there is little water loss from the hidden river. For the time being, the drainage of the tunnel is very small and the water drainage and generation are maintained at balance generally. The drained water inside the tunnel sources from the condensed water by air and the water penetrated or leaked from the substrate through the capillary pipe, and the construction for the tunnel produces no influence to the underground river and the water environment around the river. (3) Yesanguan Tunnel Entrance Segment The volume of the drained water within the Bid Segment during construction is stable and much less than the designed volume (accounting for approx. 0.45% of the designed volume), and there is no clear data indicates that the tunnel drainage produces any influence to the ground water, and the supplementation of the atmospheric precipitation for the ground water is much more than the drainage water from the tunnel, in accordance with the current monitoring data, the tunnel

2009 Interim Environment Monitoring Report of Yichang-Wanzhou Railway construction produces no remarkable influence to the environment around. Exit Segment The volume of the water drained through the tunnel during the construction within the bid segment increases much more than that in the last monitoring cycle, which is mainly caused by the great increase in the atmospheric precipitation that effectively mitigate the influence of the tunnel drainage to the ground water. There is no clear data indicates that the tunnel drainage produces any influence to the ground water. The atmospheric precipitation brought a plenty of rainwater in this season, which greatly enhanced the supplementation capacity, although the increase in the tunnel drainage is very big, the increment thereof mainly comes from the atmospheric supplementation that is drained not passing through the ground water system, therefore, the tunnel drainage constitutes no threat to the groundwater resource in this season. (4) Gaoyangzhai Tunnel There is no sudden water or mud flow occurring in this season, and the drainage volume is relatively stable, in addition, there is no remarkable relation between the tunnel drainage and the external monitoring points. For the time being, there is no abnormality in the external environment. The water drained through the tunnel is mainly the leaked or penetrated water and it saw a great decrease comparing with the volume of the drainage water during the excavation and construction for the main body of the tunnel, which show that the second-layer liner has a good effect in water resistance. At present, the drainage water is mainly the leaked or penetrated water drained through the hole of the second-layer liner, and such water is permitted to discharge as it is with small volume and cannot produce any disaster to the environment. (4) Jinzishan Tunnel The routine drainage volume of the tunnel doesn’t reach 300m3/d, and the water drained through the tunnel main comes from the condensed water in the air and a little water penetrated or leaked from the soil, the tunnel construction produces no influence to the environment around.
