1.2 Project characteristics

Lanzhou–Chongqing Railway goes through, from the north to the south, such three geomorphic units as Loess Plateau, high and medium mountains area of the Qinling Mountains and low mountains and hills area in Sichuan Basin 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 Qinling’s high and medium mountains area and mid - subtropical 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 biodiversity in Yangtze River Basin on the south of Qinling Mountains is higher than that in the Yellow River basin.

The land erosion area in the drainage area of the Yellow River basin, in which the railway goes, is big, and the erosion intensity is mainly medium, but it is serious or extra serious for some sections. The erosion is mainly hydraulic erosion 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

3 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 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, and the cultural relic protection zones and are greatly affected by human activities. Emphasized protection targets: Ancient Xiaguanying relic, ancient Shannashuzha relic, Yuhe Natural

Reserve of Gansu Province, Sichuan Maozhai Nature Reserve, Wetlands Natural

Reserve of Jialing River Source, Myxiocyprinus Asiaticus of Natural Reserve, etc.; Ecological environmental protection main targets: cultural heritage, the vegetation, rare animal and land resources, etc. along the line. It is the important 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 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 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 subgrades will be replaced by bridges in 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

4 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 impacts 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 volume of the cubic meter of earth and stone 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 cubic meter of earth and stone, 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 inspect the execution of environmental protection measures during construction of the project on the basis of the design and EIA of this project and to affirm the achievements, find out existing problems and give suggestions on countermeasures. 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 ADB have been met. Key points that attention should be paid to during environment monitoring include:  Whether the environmental impact during construction is consistent with the environmental problem put forward in the EIA report;  The accomplishment of environmental protection measures given in EIA report;  Identify and find out any unexpected environmental problems and put

5 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 forward recommended 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 Beibei

North, 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 being put into operation after completion. For every half year of the construction period and for every year of the two years after completion, one environment 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 Materials Management Department of China Railway Corporation,

Lanzhou-Chongqing Railway Co., Ltd., Development Planning Department of the China Railway and Asian Development Bank.

The monitoring report should contain the following content:

Impacts on the ecological environment imposed by construction of stations, tunnels, bridges and subgrade inside key ecological environmental protection zones such as natural preservation 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 (area) on the water and soil conservation facilities, disturbance imposed by construction to vegetation and recovery and treatment measures;

Restoration measures taken for land for temporary use such as construction

4.1Implementations of protection measures for key environment-sensitive protection objects

I. In the region where the Xiaguanying−Min County section is located, there is one important sensitive protection object: Zhang County Province-level Natural Reserve for Brachymystax Lenoks Tsinlingensis (presently Zhang County National Nature Reserve for Rare Aquatic Lives). Overview of Zhang County National Nature Reserve for Rare Acquatic Lives On February 2, 2005, the People’s Government of Gansu Province approved File Ganzhenghan [2005] No.4 to set up Gansu Zhang County Province-level Natural Reserve for Brachmystax Lenoks Tsinlingensis, which focuses on protecting brachmystax lenoks tsinlingensis (a national Level II protected aquatic wildlife). In March 2010, the Bureau of Zhang County Province-level

Natural Reserve for Brachmystax Lenoks Tsinlingensis submitted the Application for Establishing National Nature Reserve and associated documents to the National Nature Reserve Assessment Committee step by step for setting up Gansu Zhang County National Nature Reserve for Rare Aquatic Wildlife, which was finally approved and, then, in File Guobanfa [2013] No.48, it was approved by the General Office of the State Council to be upgraded as a national nature reserve.

(1) Environment Impact Assessment Stage The EIA Report does not cover relevant content relating to Lanzhou-Chongqing Railway running across Zhang County Province-level Natural Reserve for Brachymystax Lenoks Tsinlingensis (presently Zhang County National Nature Reserve for Rare Aquatic Wildlife). In October 2012, the Bureau of Gansu Zhang County Natural Reserve for Brachymystax Lenoks Tsinlingensis issued the document Zhangqinguanzi [2012] No.3–the Letter on Going through Required Formalities for Construction of Lanzhou−Chongqing Railway in Zhang County Natural Reserve for Brachymystax Lenoks Tsinlingensis as soon as possible to the project undertaker Lanzhou−Chongqing Railway Co., Ltd., requiring that the project undertaker should contact the Aquatic Wildlife Protection Office of Gansu Agriculture Department or the Bureau of Zhang County Natural Reserve for Brachymystax Lenoks Tsinlingensis as soon as possible to verify the railway route, jointly discuss and work out the protect plan and take practicable protection measures. In January 2013, Lanzhou-Chongqing Railway Co., Ltd. entrusted Gansu Fishery and Water Environment Protection Station to work out the Aquatic Life Assessment Report. The Aquatic Life Assessment Report and its reply required the project undertaker to perform associated promises and agreements comprehensively, ascertain and implement various protection measures, strictly ascertain and

20 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 implement relevant vibration and noise reduction measures in the operation period so as to minimize the impacts to be imposed by railway operation on brachymystax lenoks tsinlingensis. It also required that the project undertaker should hold responsible for the ecological compensation funds for natural reserve monitoring, fishery management, artificial domestication center construction, fish fry releasing station and rescue station construction, enrichment and release and so on.

(2) Opinions of competent authority

In the project construction period, Gansu Provincial Agricultural and Pastoral

Department approved the construction of this project by issuing Gannongmuhan

[2016] No.65 Reply of Gansu Provincial Agriculture and Animal Hudbandry

Department to the Report on Assessment of Impacts of Lanzhou-Chongqing

Railway to Zhang County Province-level Natural Reserve for Brachymystax

Lenoks Tsinlingensis (Presently Zhang County National Nature Reserve for Rare

Aquatic Wildlife).

(3) Field Inspection The field inspection shows that Lanzhou-Chongqing Railway actually built 3 bridges (Zhoujiazhuang Tiegouhe Major Bridge (DK151+676), Chichali Medium Bridge (DK152+918) and Hujiawan Tiegouhe Medium Bridge (DK155+949) over Tiegou River and its core branches in Zhang County Province-level Natural Reserve for Brachymystax Lenoks Tsinlingensis (presently Zhang County National Nature Reserve for Rare Aquatic Wildlife). These projects have not set up any piers in water and are not materially running across the Nature Reserve. During the construction, the project undertaker has basically satisfied the requirements set forth in the Environment Impact Assessment Report and its

21 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 reply, reinforced various protection measures, and arranged the ecological compensation funds for natural reserve monitoring, fishery management, artificial domestication center construction, fish fry releasing station and rescue station construction, enrichment and release and so on. For examples, it has strengthened the storage and management of construction materials, arranging them far away from rivers and taking appropriate rainproof and damp-proof measures; it has arranged appropriate centralized storage places for solid wastes, arranging them far away the rivers and in low places, while taking perfect wind-proof, rainproof, fencing and retaining measures.
