1. INTRODUCTION

This is the fourth EMP implementation progress report prepared by Guiyang ADB-loan Project Management Office (GPMO) with assistance from Artelia Consultants, for project “Guiyang Integrated Water Resources Management Project (ADB Loan 2573-PRC)”. The report covers the progress for the period from July to D of 2014.

The “Guiyang Integrated Water Resources Management Project” covers 5 sectors of water resource management, including urban water supply, rural water supply and irrigation, irrigation system rehabilitation, soil and water conservation, and small water storage structure, totally loaned $150 million US dollars from ADB. According to the Environmental provisions in the Project Agreement (June 2010, PAL: PRC 38594):

● For those water supply dam Subprojects, particularly the Yudongxia dam, GMG shall ensure an appropriate classification of EPZ and determine and stipulate related regulations for preserving water quality of the respective reservoir. Such regulations may include land use zoning and control of chemical fertilizers/pesticides use, wastewater discharge and aquaculture development in the EPZ area. To ensure the preservation of the income and livelihood of local communities that may be affected by such regulations, GMG shall ensure that a PES mechanism to maintain the agreed level of water quality by providing sufficient compensation to upstream government and affected communities is established and implemented.

● GMG shall cause each local government and the IAs to construct, operate, maintain, and monitor the Project facilities in strict conformity with: (a) all applicable laws and regulations, including national and local regulations and standards for environmental protection, health, labor, and occupational safety; and (b) ADB’s Environment Policy and the environmental mitigation and monitoring measures detailed in the approved EIAs, IEEs, SEIA, SIEE, and EMP for the Project.

● GMG, through the local level PMOs, shall ensure that the IAs: (a) provide monthly environmental progress reports to the Guiyang PMO, which will prepare and submit to ADB semi-annual environmental reports in a format acceptable to ADB until loan closing. The semi-annual reports will address, among other issues, cumulative impacts of the Project; (b) where required, make an SEIA or SIEE available to the general public at least 120 days before each Subproject is approved; and (c) for each Subproject, carry out public consultations during the early stages of the EIA field work and when the draft EIA is available.

To response to the above requirements of ADB focusing on environment protection and environment management, under the supervision and GPMO and the assistance of ARTELIA Consultants, the subproject IAs have endeavored efforts to implement the corresponding EMPs. Through periodical internal inspections and EPB checks, the environment impacts resulting from project implementation have been closely monitored and controlled so as to guarantee subprojects’ smooth implementation.

Due to the subprojects are numerous and dispersed, to timely clarify subprojects’ environment behaviors and performances, GPMO organized regular site-visits (on a monthly basis), periodical document review, and report collection. During this reporting period, GPMO and ARTELIA Consultants had organized one round of site visit for environment inspection of ongoing subprojects in August 2014, especially focusing on the inspection of construction sites, material storage and spoil area





management, wastewater treatment, noise control, solid waste management and on-site health & safety management. In view of difference of subproject progress, during this reporting period, special attention has also been paid to the impoundment for finished reservoir (Yudongxia Reservoir) and documentation preparation of newly proposed subproject (Hongyan Reservoir) in response to ADB mid-term review.

Based on the information collected, GPMO has developed the EMP implementation progress reports on a semi-annual basis to:

1) Summarize environment management works which has been implemented by GPMO and IAs in the six-month period;

2) Assess the resulted environmental impacts caused by subproject implementation with reference to the conclusions of subproject EIAs, in terms of resulted and anticipated impacts during both construction and operation periods;

3) Evaluate the effectiveness of mitigation measures already undertaken;

4) Review environment monitoring activities and monitoring results; and

5) Identify key environmental issues and forward suggestions for further improvement and EMP updating.

Accordingly, the Semi-annual Environmental Progress Report mainly covers the following chapters and appendices.

2. PROJECT PROGRESS

2.1. PROJECT BACKGROUND

Guizhou Province is one of the poorest provinces in the PRC, with the second lowest rural income after Tibet, and the lowest level of urban income of any province. The capital of the province, Guiyang Municipality (GM), is its political, economic, cultural, technical and service center, and a major transportation hub of southwest PRC. In 2008, GM has an estimated population of 3.6 million, of which about 2.4 million reside in the main urban area, with the remaining 1.2 million in suburban or rural areas. About 574,000 people (16% of the total population) are ethnic minorities who mainly reside in the rural areas. The income differential between the rural and urban population is high, and about 25% of the rural population live on an income of less than CNY1,200 ($158) per capita per year. As the economic hub of the province, GM has a rapidly increasing population and industrial development, and hence increasing demand for water. Servicing this population and related municipal and industrial water demands is causing a severe strain on the existing water supply facilities.

On the other hand, both urban and rural areas of GM are on the mountainous ridge of the watershed boundary between the Yangtze River basin to the north and the Pearl River basin to the south. Annual average precipitation is quite high but large evaporative losses and uneven distribution present particular challenges for capturing and storing water, much of which drains into rivers as quick surface flows through numerous short creeks and streams that run deep in valleys, or through fast-flowing deep aquifers (groundwater rivers) through the limestone layers (karst areas).

The GM urban water supply infrastructure is in poor condition and its rapidly increasing urban population has seriously stretched the existing water supply capacity, resulting in reduced water pressure, and water rationing in dry periods. In the surrounding rural area, shortage of water for potable use and irrigation is perceived as a critical constraint to improving rural incomes and living standards. The current management of the GM water sector is not well integrated. There is vertical fragmentation with different responsibilities between provincial, municipal, and district/county levels and there is also horizontal fragmentation with responsibilities for water sector management split between different government departments.

In recent years, the Government has recognized the need to improve the comprehensive management of water resources, apply approaches consistent with integrated water resources management (IWRM) methodologies, and shift emphasis towards managing demand, including the use of economic mechanisms.

The implementation of “Guiyang Integrated Water Resources Management Project” will contribute solutions to achieve greater coordination and optimization of water supply and demand management activities in line with IWRM principles.

To fund this Project, Guiyang Municipal Government has applied for a loan of $150 million US dollars from ADB’s ordinary capital resources to cover part of the total $439.2million estimated cost. The remaining counterpart funding will come from domestic sources. The ADB loan became effective on 4 January 2011. The loan closing date is 30 June 2016.

In November 2014, a mission from ADB conducted the mid-term reivew for the





project, when 1 core and 49 noncore subprojects have been withdrawn and 2 new noncore subprojects (Hongyan medium-sized reservoir and Hongyan water treatment plant) will be included. Considering the updated project schedule, particularly the schedule for the two new components, the mission and GPMO tentatively agrees to extend the current loan closing date of 30 June 2016 to 30 June 2018, by 2 years. Relevant approval procedure by national authorities and ADB is still ongoing.

2.2. PROJECT SUMMARY

The Project will adopt a sector investment approach with five key infrastructure development activities to be financed.

● Urban Water Supply comprising the establishment of one medium-sized reservoir and two small reservoirs,1 including the construction of dams, water conveyance tunnels, transmission pipelines, four water treatment plants, and the extension of the municipal water distribution networks;

● Rural Water Supply and Irrigation comprising the construction of up to 43 small reservoirs, including about 3 for county water supply, 20 for water supply and irrigation at the township level, and 20 for human and livestock water supply and small irrigation systems. Many of these include investments in water conveyance systems, small township water treatment facilities, and irrigation systems;

● Irrigation System Rehabilitation comprising rehabilitation and upgrading of up to nine irrigation systems covering a total area of 195,447 mu (13,030 hectares [ha]), including installation or repair of intake structures, canals, and aqueducts;

● Soil and Water Conservation comprising farmland restructuring, conversion of sloping farmland to terraces and tree or grass planting, and fruit tree planting, to protect the upper catchments of the water sources (about 800 square kilometers [km2]) from soil and water losses;

● Small Water Storage Structures comprising the provision of up to 105,100 small water storage tanks in rural areas to catch spring water for human consumption, and rainwater for irrigation and livestock consumption.

The project will also address non-structural interventions including institutional development and capacity strengthening, stakeholder participation, water tariff adjustments, and demand-management measures.

Following the sector lending modality, six core subprojects representing the five main types of infrastructure development activities were identified during project preparation. After the midterm review in Nov. 2014, one core subproject is withdrawn. The core subprojects serve as representative models for the design and implementation of similar noncore subprojects to be financed under the Project. The five core subprojects are the Yudongxia reservoir and water treatment subproject for urban water supply, the Jinlong and Liaojiuzai reservoir subprojects for rural water supply and irrigation, the Wudang irrigation rehabilitation subproject, and the Xifeng County small water storage tanks subproject.

1 Ministry of Water Resources. 2000. Standard for Classification and Flood Control of Water Resources and

Hydroelectric Project. Beijing (SL252–2000). A reservoir with a capacity of more than 10 to 100 million m3 is

classified as a medium-sized reservoir and that with a capacity of 0.1 to 10 million m3 is classified as a small

reservoir.

2.3. PROJECT IMPLEMENTATION STATUS

As mentioned above, according to the Aide Memoire of ADB Midterm Review Mission (11-17 November 2014), from the originally planned six core subprojects and sixty non-core subprojects, one core subprojects (Upstream and Midstream of Nanming River Catchment in Huaxi) and 49 non-core subprojects have been or will be withdrawn from the project; However, 2 non-core subprojects (Hongyan medium-sized reservoir and Hongyan water treatment plant) are being proposed.

In particular among the non-core subprojects, the following changes have been made in corresponding sectors:

Reservoir subprojects (urban water supply and rural water supply & irrigation):

39 reservoir sub-projects have been dropped out, and 7 reservoir subprojects

have been kept. Additionally, two new subprojects (Hongyan Reservoir and

Hongyan Water Treatment Plant) are proposed to be added in during the ADB

Mid-term Review;

Irrigation system rehabilitation: 6 irrigation rehabilitation subprojects have been

dropped out, and 1 subprojects (Wengjing and Yangchang) were kept;

Soil & water conservation: The only one core subproject has been withdrawn,

and all the 6 non-core subprojects have been kept;





Small water storage structure: 4 non-core subprojects have been dropped out,

and 2 subprojects have been kept.

The general progress of ongoing subprojects has been summarized in the table below.

Note: 1. The above information is updated based on the latest quarterly report of 2014 (4th of 2014) currently available; 2. The percentages in the brackets indicate the physical progress of civil works for corresponding subprojects under construction; 3. The subprojects in bold refer to the core subprojects identified during project preparation in 2009.

As shown above, Xifeng Small Water Storage Structure Subproject is the only subproject completed. Among the implemented subprojects, the subprojects for irrigation system rehabilitation and soil & water conservation are being implemented phase by phase without major ongoing construction activities. Therefore, the EMP implementation progress report for this reporting period will focus on the seven ongoing reservoir subprojects, namely Yudongxia, Liaojiuzhai, Jiancaogou, Bai’anhe, Jinjiaqing, Jinlong and Maozhulin. Also, special attention will be paid to the two newly proposed components, Hongyan Reservoir and Hongyan Water Treatment Plant Project, particularly on the progress of their EIA documentation preparation in compliance with both national regulations and ADB environmental safeguard guidelines. For the new Hongyan Reservoir subproject, since only preparatory works (land preparatory activities), instead of substantial physical progress, have been implemented which have not yet triggered substantial EMP implementation, no detailed description on the implementation status of environmental management is included in this report.





3. INSTITUTIONAL ARRANGEMENTS AND RESPONSIBILITIES FOR EMP IMPLEMENTATION

Various organizations with different environmental management responsibilities – GPMO, GEPB, Ias, environmental management consultants, contractors, and construction supervision companies – have been involved during project implementation, and have been involved in the implementation of the EMP, as presented in this chapter.

3.1. INSTITUTIONAL STRUCTURE FOR ENVIRONMENT MANAGEMENT

The PMO, contractors, and Ias will each nominate full-time dedicated, trained, and qualified environment specialists to undertake environmental management activities and ensure the effective implementation of the EMP.

To actively respond the requirements in Project Agreement, in terms of institutional arrangement, a vertical framework with 3 levels had been set up for the project environment management:

Level 1: GPMO, which had set up an Environment Management Unit (EMU) since the beginning of the project, with 2 staff (headed by GPMO Director Ms. Meng Jianjian, daily coordinated by full time staff Mr. Yang Yang).

Level 2: Subproject Implementation Agencies (Ias), which had designated 1~2 employees each in charge of EMP implementation, report to GPMO periodically.

Level 3: Contractors/Supervisors and Operators, which had designated 1~2 n full-time staff in charge of daily environment management, report to Ias periodically.

Besides above three levels on environment protection, Guiyang EPB and County EPBs also organize on-site inspection to subprojects, supervise the fulfillment and effectiveness of environment protection measures, and provide comments and recommendations on periodic or random base.

Environmental specialist from ARTELIA Consultants has also been mobilized since November 2012; assisted GPMO in the preparation of the EMP implementation progress report since September 2013.

The following figure summarizes the institutional structure/relationship of various agencies.

3.2. ENVIRONMENT RESPONSIBILITIES

Guiyang EMU, under GPMO, take charge of project administration and coordination, take overall responsibilities for implementing and supervising environment management, environment monitoring, and mitigation works of all subprojects, and report to ADB periodically in accordance with the signed project agreement.

Subproject IAs, carry out detailed management of subproject. From project preparation and engineering design, to civil works construction and project operation, the IAs will be largely responsible for environmental management to ensure that the EMP is carried out effectively and they are also required to report to GPMO and EPB periodically in accordance with the signed project agreement.

Construction Contractors are responsible for implementing mitigation measures during construction, carry out monitoring and control project’s daily environment performance, and, report to IAs periodically.

Construction Supervision Company (CSC), as Supervisors designated by IAs, is responsible for on-site environment management control, supervise the contractors’ environment activities and proper implementation of mitigation measures during project construction.

Operators are responsible for implementing environment protection measures during project operation, carrying out necessary environmental monitoring, supervising in line with environment regulations and standards and reporting to IAs periodically according to the defined subproject EMPs.

Consultants (environmental specialist from ARTELIA) help GPMO to supervise EMP implementation by IAs, prepare required reports for ADB review and approval, and carry out necessary environmental trainings.

EPBs will organize periodically or randomly inspection to both construction sites





(during construction) and operated projects (during operation) to review environmental qualities and environmental management conditions of the implemented subprojects, such as wastewater treatment, solid waste disposal, camp neatness, workers’ healthy situation, and safety situation, and official letters will then be issued to the IAs requesting improvements if any incompliance exists.

The following table summarized the environmental responsibilities of each agency in different phases of the Project.

● Reporting and supervision.

4.2. REVISION OF SUBPROJECT EMPS

In April 2013, the GPMO officers, together with the environmental specialist from Artelia Consultants visited all the sites of ongoing subprojects and the subprojects to be constructed recently, particularly, the reservoir subprojects under construction and to be constructed soon. According to the observations, the EMPs of visited subproject developed during ADB PPTA phase have been generally implemented in the construction activities. However, it is also noticed that, as part of the EMP, the original environmental monitoring plans (required in ADB SEIA and EMP dated August 2006) was not tailored to the existing conditions of project sites in some cases.

Based on key findings of site visit and discussion with different PIUs, with the assistance of environmental specialist, in May 2013, GPMO has proposed the following adjustments of environmental monitoring plans for the ongoing or recently to-be-constructed subprojects for a more practical and efficient operation. All these adjustments have also been reviewed and put into trial implementation by corresponding PIUs since June 2013 to check their applicability.

With ADB’s no-objection as indicated in the Aide Memoire of Review Mission in November 2013 and with the good operationability and satisfactory monitoring





results indicating the environmental compliance of related subprojects (as presented in the following section), the revised environment monitoring requirements have been officially implemented in a strict way since November 2013. Since then, there is no further EMP revision during this reporting period.

For the two new subprojects, the EIA report and EMP of Hongyan Reservoir project is to be finally approved by ADB in early 2015, while the EIA of Hongyan Water Treatment Plant project is still ongoing and corresponding EMP will be available to support the project implementation so that the construction of the water treatment plant will be completed and ready at the end of reservoir impounding.





5. ENVIRONMENTAL COMPLIANCE

5.1. GENERAL COMPLIANCE

China has regarded environmental protection as one of its fundamental policies to guarantee a sustainable development of the nation in the 21st century. China’s existing environmental regulatory regime remains multi sourced (international treaties, national environmental laws, regulations, rules, measures and policies, standards and local legislation) but can essentially be classified into two categories: environmental management legislation and environmental pollution prevention and control legislation.

For construction projects in China, Environment Impact Assessment (EIA) and Environment Check & Acceptance of Project Completion (ECAPC) are two most important regulations to be compliant with. These two regulations are regarded as basic references for project environment protection respectively for construction phase and operation phase.

For GIWRMP, all the implemented subprojects had strictly followed national EIA procedures, completed EIA reports and obtained EPB approval. During subproject bidding process, the EMP requirements for construction period have been included as part of contractual obligations for the contractors. For the only completed subproject, Xifeng Small Water Storage Structure Subproject, the Environment Check & Acceptance of Project Completion (ECAPC) has been implemented and approved by local EPB.

As per the EARP formulated during project preparation in 2009, following the environmental requirements of ADB, all the investments under this project are subject to categorization to determine environmental assessment requirements. If the subprojects are identified as Category A or Category B, either an Environmental Impact Assessment (EIA, for category A) or an Initial Environmental Examination (IEE, for category B) will be required for ADB review and no objection before the subproject implementation.

As detailed in Section 2.3, based on current project progress, this semi-annual environmental report will focus on the EMP implementation of seven reservoir subprojects under construction. According to the results of desk review and site visit, the general EMP compliance of involved subprojects by December 2014 is summarized in the Matrix below. More details are presented in the following sections.

3. Since the pending civil works of Maozhulin subproject was only resumed since late December 2014, there is no practical implementation of EMP for the subproject during this reporting period. 4. The civil works of Liaojiuzhai subproject has been completed in September 2014; therefore, there is no environmental monitoring during this reporting period.

EIA Preparation Progress of Hongyan Reservoir Subproject

Among others, Hongyan Reservoir subproject, the newly added project, has been identified as a Category A subproject for EIA preparation. This means a Chinese EIA and an English SEIA would be required respectively for domestic and ADB approval, covering the examination of the project’s potential impacts, recommendation of environmentally sound project design by comparing all possible alternatives and at least twice of public consultation during EIA preparation. The mitigation measures and monitoring plan proposed in the EIA will be incorporated into the Environmental Management Plan (EMP).

With the support of international environmental consultant, the entrusted domestic EIA consulting team, Guiyang Survey and Design Research Institute under China Hydropower Consulting Group completed Chinese EIA report in late October 2013. Its final revision was approved by the Guiyang Municipal Environmental Protection Bureau on 24 February 2014.

Accordingly, the TA consulting team has developed the SEIA and submitted to ADB for review and information disclosure in June 2014. In consultation with Regional and Sustainable Development Department of ADB, it was agreed that an SEIA report will be prepared and disclosed on ADB’s website, while the domestic EIA report in Chinese will count as the original EIA report. Final comments of ADB on these documents will be provided by ADB before the finalization and disclosure of SEIA on ADB website in early 2015. Considering the 120-day disclosure requirements, the official approval of the SEIA report by ADB is expected in July 2015.

EIA Preparation Progress of Hongyan Water Treatment Plant Subproject

For the Hongyan water treatment plant, no domestic environmental assessment has been completed yet. It was agreed that the PMO will prepare a categorization form, indicatively for a Category B project. The required environmental safeguards documents will an English SIEE report, complimented with an English translation of the domestic EIA report. The SIEE and domestic EIA reports will be prepared in a timely manner so that the construction of the water treatment plant will be completed and ready at the end of reservoir impounding. It is noted that land clearing has started already. Although this is allowed by the Chinese system, the assessment will include the impacts of land and forest clearing, including a review of the necessary domestic approvals (e.g., cutting of trees), and cultural relics (e.g., the site is immediately beside tombstones).

5.2. IMPLEMENTATION OF ENVIRONMENTAL MITIGATION MEASURES FOR CONSTRUCTION PERIOD

The proper implementation of environment impact mitigation measures, which will give direct impacts to the projects’ environmental performance, is always a key issue tracked and supervised by GPMO.

To achieve a better understanding on the practical environment status of each subproject, GPMO, with the support of consultants, organized site-visits, meetings and interviews to subprojects in August and November 2014. During the visits and meetings, the EMP implementation status of each ongoing subproject has been reviewed for continuous improvements.

In general, all the reviewed subproject construction has been implemented together





with the corresponding EMPs and Environmental Management Rules for Project Construction developed during project preparation in 2009. The description specific to each ongoing subproject is presented in the following sections. With the continuous commitments of subproject IAs on the implementation of corrective measures, it is notable that most of the previously detected incompliances have been corrected during this reporting period. The details are presented below.

5.2.1 YUDONGXIA RESERVOIR*2

The construction of Yudongxia Reservoir subproject was started in December 2011. To strengthen environmental management of the subproject, the contracted external environmental supervision team from Guizhou Province Environmental Engineering Evaluation Center has been mobilized since October 2012. Before the formal mobilization, the supervision team has developed a detailed environmental supervision plan based on the subproject EMP, which has been approved by the project owner in Sep. 2012.

During this reporting period, the team has submitted another six monthly environmental supervision reports (No.22~No.27) for the project based on their routine supervision work according to the environmental supervision plan. There are four main civil works contracts implemented for the subproject, namely:

Contract 1: Water diversion system (including steel pipes, power house, water diversion tunnel and so on) and supportive works;

Contract 2: Main dam and auxiliary dam, curtain grouting in head area, access tunnel on left bank, adit in head area, upstream and downstream cofferdam;

Contract 3: Curtain grouting on left bank, temporary road works.

Contract 4: Buildings and structure of water treatment plant, pipelines and high-level tanks

In the last six months, the first three contracts have been generally complemented, including main dam, curtain grouting and water treatment plant; the laying of associated distribution network is still ongoing and mostly done. With impounding, the reservoir storage level has reached the normal storage level of 1075m, while the WTP has been put into commissioning since July 2014 with good results.

The provided environmental supervision reports clearly show that environmental mitigation measures specific to each construction site have been continuously implemented by the contractors during this reporting period based on subproject progress, including:

- Wastewater management (mainly for Contract 4 during this reporting period):

o Domestic wastewater: Dry latrines have been installed in the worker camps,

which (or septic tanks when available) are used for domestic wastewater

treatment with regular cleaning by local farmers;

- Air quality control (mainly for Contract 4 during this reporting period):

o The unpaved access roads are sprinkled with water and swept from time to

time by the contractors;

o Construction equipment and vehicles are regularly and properly maintained;

o It is forbidden to incinerate domestic solid waste within the construction area;

o Open sand and stone dumps are regularly sprinkled with water.

- Noise control (mainly for Contract 4 during this reporting period):

o Speed limit signs has been installed along access roads;

o No horn is allowed within the project site;

o Low-noise and low-vibration construction equipment are selected;

o No construction is allowed at night and between noon and 2pm.

- Solid waste management (mainly for Contract 4 during this reporting period):

o For this reporting period, spoil is mainly from pipeline excavation, which is

dumped along the pipelines for later backfilling;

o Domestic solid waste is collected and regularly cleared.

- Ecology:

o The excavation is implemented by strictly following the design;

o For all the sites, the greening works of excavated side slopes is being

implemented as designed;

o The discharge pipe at subsidiary dam and tailrace of power station is used

for the discharge of ecological flow during impoundment;

o The site and vegetation rehabilitation of closed spoil disposal site and

construction camps is being implemented by respective contractors.

- Health and safety: A dedicated health and safety supervision team under the

contracted construction supervision company has been working on site with

regular inspection for earlier detection of any potential health and safety risk

during construction and to follow up corresponding correction actions. All the

detected health and safety issues have been formally reported and filed, and

active measures have been taken accordingly with following-up inspection.

- Historic site: For the only identified ancient stone bridge (built in early years of

the Republic of China), relevant records (mainly photos) have been taken as per

the original EMP during reservoir clearing.





As observed in the field visit in August 2014, the environmental management of Yudongxia Reservoir subproject site is generally satisfactory with proper mitigation measures taken against construction impacts. In particular, the following observations related to the environmental performance of the subproject has been made:

1) Replantation of ancient trees in reservoir area: As part of reservoir clearing, the replantation plan for affected ancient trees has been partly modified compared with the EIA phase and implemented with the guidance of local forestry department in May 2014 before reservoir impoundment. According to the modified replantation plan, there were totally 15 ancient trees in the project-affected area, in which three have been replanted successfully, four un-flooded ones have been protected in situ, and the other eight have been felled and cleared based on their conditions. The implementation of replantation plan has been validated by forestry professionals from the provincial forestry department and Guizhou University. The site visit in August 2015 showed that two of three replanted had survived and the other one had not yet grown with new branches and leaves. Following-up observations and nursing are required in the coming months.

2) Environmental Mitigation Measures for Resettlement Sites: During the visit, it was understood from the IA that the environmental protection measures for resettlement sites proposed in the original subproject EIA had been implemented or were being implemented. One resettlement site of Mitangjing under construction (serving 17 households) was visited. The resettlement site was completed at the end of 2014. The following environmental mitigation measures were being implemented for the specific resettlement site:

- Water source: A high-level water tank and water supply station with the

treatment capacity of 25m3/d has been constructed for the site on the top of

a nearby hill, which is connected with the site by DN90 water supply pipes.

- Domestic wastewater treatment: To protect the reservoir water quality from

being polluted, a supporting wastewater treatment plant will be built with

domestic fund near the resettlement site.

- Public education on environmental and health protection: A community

square was being constructed near the residential houses, which will

provide a suitable space for public recreation and education on

environmental and health protection.

3) Vegetation rehabilitation of spoil disposal site: The original spoil disposal site near auxiliary dam was visited during the August visit, which has been levelled and compacted with the sowing of grass seeds in June 2014. Due to high gravel content of the site, it was observed that grass growth was not good during the visit. Additional sowing may be necessary.

4) Commissioning of Yudongxia Water Treatment Planta: Yudongxia Water Treatment Plant has been completed and put into commissioning since July 2014. The plant has been fully staffed as scheduled (about 20 managers and operators). The treatment capacity during the August visit was about 10,000t/d. The operational results were generally good with the compliance of all the water quality indicators except slightly high residual chlorine in treated water. The water treatment plant was actively applying for hygiene license for earlier water sale.





5) Approval to be acquired from local environmental protection authority for implemented variation orders: It is understood that several changes have been made during project implementation, for example, addition of power generation system, changes of high-level water tank and distribution pipelines, adjustments of dam height and crest width, etc. According to the national environmental impact assessment regulations, these project changes need to be reported to local environmental protection authorities for approval before the final environmental protection inspection and acceptance for project completion. According to the IA, the environmental protection inspection and acceptance procedure will be implemented for the whole subproject, instead of for Yudongxia Reservoir component and WTP component respectively, which will therefore formally started upon the completion of the whole subproject and the acceptance inspection of associated water and soil conservation works in early 2015. Relevant progress will be updated in the next semi-annual report.

According to the provided monthly environmental supervision reports (No.22-No.27), since Jul. 2014, no rectification notice on environmental incompliance has been issued by environmental supervisor. By the end of December 2014, there is neither environmental conflict/accident nor any environment complains received from local residents related to the subproject.

5.2.2 BAI’ANHE RESERVOIR

As one of the non-core subproject, Bai’anhe Reservoir is still under construction and has been completed by 72% by December 2014. As reported by the project supervisor in the monthly construction supervision reports (dated Jul.-Dec. 2014), applicable environmental mitigation measures have been taken in accordance with the subproject EMP, including the treatment of construction wastewater with settling tank on site before discharge, regular cleaning of construction vehicles and water sprinkling within construction site to reduce flying dust, noise control by using low-noise equipment with regular maintenance, proper collection and disposal of domestic solid waste and close monitoring on the effectiveness of epidemic disease control. It is understood that the operation of rock quarry has been stopped and the spoil disposal site has been properly managed. By the end of December 2014, there is neither environmental conflict/accident nor any environment complains received from local residents during construction. During the reporting period, the subproject IA has been reminded to pay high attention to reservoir clearing, site rehabilitation (in particular, spoil disposal site) and re-vegetation works in the last phase of project construction, which will be the focus of environmental management during next reporting period.

5.2.3 LIAOJIUZHAI RESERVOIR*

The construction of Liaojiuzhai Reservoir subproject (core subproject) was started in March 2013 and main works (including main dam, flood discharge channels and downstream irrigation channels and the upstream flood diversion channels) has been completed in September 2014. It is understood in the Aug visit that, since most of land downstream of the reservoir has been changed from agricultural use to industrial use, the irrigation area targeted by the subproject has been reduced from the original 1700mu to about 100mu and the total length of irrigation channels implemented in the subproject is accordingly reduced to about 800m, which is sufficiently to meet future irrigation needs downstream. The reservoir is now waiting for the raining season for impounding. During this reporting period, the ongoing construction mainly focused on the construction of flood discharge channel and associated irrigation channel. Accordingly proper environmental mitigation measures have been taken against adverse environmental impact. For example, the construction wastewater is intercepted for settling treatment in the reservoir area; no construction works is scheduled at night; in coming spring, grass seeds will be sowed over the dam slope for greening. As confirmed by the results of environmental monitoring (as shown in Section 5.4.3), the environmental mitigation measures taken are sufficient to minimize the project impacts on surrounding environment and residents. By the end of December 2014, there is neither environmental conflict/accident nor any environmental complaints received from local residents.

5.2.4 JIANCAOGOU RESERVOIR

The construction of Jiancaogou Reservoir subproject was started in March 2013, however, little progress has been made until Mar. 2014 due to resettlement issues and conflict between the proposed blasting activities for dam excavation and the presence of nearby railway bridge. With the subproject IA’s coordination on design variation, the construction was restarted in Apr. 2014, and the method of stone excavation was changed from the proposed blasting and normal mechanical excavation to minimize the impacts on ongoing high-speed railway construction nearby. According to the provided monthly construction supervision reports (dated Jul., Aug., Sep. and Dec. 2014), during this reporting period, the dam excavation has been completed in late November 2014, and the concreting and grouting works have been started in December 2014. The foundation excavation of associated WTP has been completed in December 2014. During construction, the following environmental mitigation measures have been taken, including protection of surrounding vegetation during excavation, and the installation of safety fencing and warning signs around the site. Additionally, the following findings have been identified during this reporting period in relation to environmental management of the subproject:

1) A Φ300 water supply pipeline of local water supply company going through the

dam site was noticed to be cut off by project construction during last reporting period. With active coordination of subproject IA, contractor, construction supervisor and relevant local authorities, an emergency action plan has been developed and implemented to address this issue by adding a section of bypass elbow pipe to guarantee the downstream water use.

2) With the completion of excavation at dam site, all the generated spoil at dam site





has been properly disposed at the designated spoil disposal site and partly utilized for road pavement. During the excavation in raining season, the contractor and construction supervisor have closely monitored the upstream the flow rate and site conditions. No barrier lake and flooding risk has ever occurred to the construction site.

3) A path costing RMB 200,000 has been constructed by the subproject IA specially for the villagers living on the hill top near the construction site.

4) As the dam is situated near existing railway bridge and ongoing construction site of high-speed railway project, it is suggested to strength the inspection and monitoring of dam safety during the subproject construction and future operation.

The only environmental complaint during this reporting period was received from nearby villagers in July 2014 in relation to the impacts of excavation noise at night. The subproject IA has taken immediate action to stop all the construction activities at night to address the issue.

5.2.5 JINJIAQING RESERVOIR

The construction of Jinjiaqing Reservoir project was started in March 2013 with slow progress due to the geological conditions found during excavation of diversion tunnel different from design document. By the end of December 2014, the subproject has been completed by 69%. The ongoing construction activities mainly focus on curtain grouting and water-taking tower. Applicable environmental mitigation measures have been taken in accordance with subproject EMP, respectively on wastewater collection and treatment, noise control, solid waste management and vegetation rehabilitation. By the end of December 2014, there is neither environmental conflict/accident nor any environmental complaints received from local residents. However, minor issues were observed during site visit, including the needs to speed up the reservoir clearing, to expand the area for spoil disposal at the Jinjiaqing Reservoir and to improve the workers’ safety arrangements on the site. The following-up information will be provided in the next semi-annual environmental report.

5.2.6 JINLONG RESERVOIR

The construction of Jinlong Reservoir was started in the beginning of 2014, and the physical progress of the subproject is 58% by December 2014. The ongoing construction activities during this reporting period mainly focus on dam site excavation and diversion tunnel. As reported by the project supervisor in the monthly construction supervision reports (Jul.-Dec. 2014), applicable environmental mitigation measures have been taken in accordance with subproject EMP, including treatment of construction wastewater by settling tank on the site, proper scheduling of construction works (no high-noise operation after 10pm) for noise control, disposal of spoil soil at designated spoil area, appropriate collection and disposal of domestic solid waste, safety management of explosive storage and use by professional blasting company and soil erosion control. By the end of December 2014, there is neither environmental conflict/accident nor any environmental complaints received from local residents.

5.2.7 MAOZHULIN RESERVOIR

The construction of Maozhulin Reservoir was started in Dec. 2013, however, the





completed works by December 2014 are only limited to access road, excavation of inlet and outlet and bolting-shortcrete support for diversion tunnel due to slow land acquisition progress and shortage of counterpart fund. During this reporting period, the construction works was suspended during July-November 2014 and was not resumed until Dec. 13th, 2014 with excavation of diversion tunnel. As reported by the subproject IA, with the construction resuming, appropriate environmental mitigation measures have been implemented by the contractor, and the details will be presented in the next semi-annual environmental report. By the end of December 2014, there is neither environmental conflict/accident nor any environmental complaints received from local residents.

5.3. IMPLEMENTATION OF ENVIRONMENTAL MITIGATION MEASURES FOR OPERATION PERIOD

Although none of the subproject has been put into operation so far, preparatory works has started to be implemented during construction as planned in the project design and project EIA report. The specific environmental mitigation measures undertaken for operation period during this reporting period are summarized in the sections below.

5.3.1 IMPLEMENTATION OF SUPPORTIVE ENVIRONMENTAL PROTECTION DESIGN

During subproject construction, the supportive design for environmental benefits has been implemented, including:

Stratified water intake: As per the original EIA report, a stratified water intake (three levels respectively at 1065m, 1050m and 1032m) has been constructed for Yudongxia Subproject to avoid the impacts of too low water temperature on the growth of downstream rice paddy during irrigation.

Supportive environmental protection facilities for WTP: The canteen of the WTP for Yudongxia Subproject has been installed with oil separator and septic tank; wastewater collection tank, sludge filter press workshop, garbage tank and greening belt have been constructed for the WTP.

Guarantee of downstream environmental flow and water use: For all the ongoing subprojects, the designed engineering measures to guarantee downstream environmental flow and water use (irrigation, drinking and fish ponds) have been implemented during construction, as listed in the table below.

5.3.2 RESERVOIR CLEARING

To facilitate the beneficial use of the reservoir after impoundment, the bottom clearing of Yudongxia Reservoir was started in late September/early October 2013 and has been completed by Jul. 2014 before reservoir impoundment, involving three districts/counties in the project area. By December 2014, the storage water level of Yudongxia reservoir has reached normal storage level, 1075m. According to the site visit, the good quality of reservoir water has indicated good practice of implemented reservoir clearing.

FIGURE 7: IMPOUNDMENT OF YUDONGXIA RESERVOIR

Since July 2014, with good project progress, Bai’anhe Subproject has also started reservoir clearing in the reservoir area. It is expected to be completed before reservoir impoundment. Further progress will be updated in the next semi-annual report.

FIGURE 8: RESERVOIR CLEARING OF BAI’ANHE SUBPROJECT IN AUG. 2014

With the coming project completion, it is also necessary to speed up the reservoir clearing of Liaojiuzhai and Jinjiaqing subprojects before their impounding.

5.3.3 UPSTREAM SOURCE PROTECTION

The upstream water source protection has already been considered in the EMPs for all the reservoir subprojects during project preparation. With the completion of





project dam, some subproject, for example, Yudongxia Reservoir, have started the preparation for the implementation of originally proposed mitigation measures for the protection of upstream water resource: to discuss with local authorities to understand relevant plans and arrangements on the establishment of water source protection zone and non-point pollution control in the river basin; to maintain the septic tank near the reservoir for future treatment of domestic wastewater generated by reservoir management staff during operation.

For Bai’anhe Reservoir Subproject, it is noticed that a specific water source protection zoning plan for the subproject was developed in Dec. 2007. As the main drinking water source of Kaiyang County in the near future, local county government has paid high attention to the protection of water source protection for Bai’anhe Reservoir. The above-mentioned “Drinking Water Source Protection Zone Planning for Bai’anhe Reservoir of Kaiyang County” has been updated in June 2008, which follows the original planning for Grade I and Grade II drinking water resource protection zone. The county water resource bureau and county environmental protection bureau will be jointly in charge of its implementation. It is told that Kaiyang County used to propose to develop a culture and education zone within the proposed protection zone; however, the proposal has been withdrawn for the protection of drinking water source. In addition, the associated Bai’anhe water treatment plant financed by local government (with the treatment capacity of 10,000m3/d) has almost been completed, which is expected to be put into use together with the reservoir.

5.3.4 DAM SAFETY REVIEW

Following ADB safeguard policies, for all the ongoing reservoir subprojects (Yudongxia, Bai’anhe, Jijiangqing, Jinlong and so on), the preliminary design documents and/or detailed construction drawings have been reviewed by the designated dam safety panel for GIWRMP before subproject construction. The expert comments on dam safety issues have been provided in formal reports. Necessary supervision and advisory services have been continuously provided by the panel during project implementation in view of specific subproject progress.

5.4. ENVIRONMENTAL MONITORING RESULTS AND THEIR COMPLIANCE

Based on the accepted revisions of environmental monitoring plans for ongoing subprojects (as detailed in Section 4.2), the IAs of relevant subprojects has continued with the cooperation with contracted environmental monitoring institutions to implement routine environmental monitoring during this reporting period. The monitoring reports have been submitted to GPMO and the key conclusions and findings from the monitoring activities have been summarized in this section. The detailed results have been attached to this report as Appendix 4.

5.2.1 YUDONGXIA RESERVOIR*

Following the agreed monitoring plan, the contracted environmental monitoring institution, Changsha Environmental Protection Vocational and Technical College, has implemented monthly environmental monitoring (Jul.-Dec. 2014) during this reporting period, covering the parameters on noise level, air quality and the quality of surface water and drinking water source.

During this reporting period, the monitoring results are generally satisfactory, as listed below:

Drinking water supply: The results are generally compliant with Class III of Surface Water Environmental Quality Standard (GB838-2002) except the indicator of fecal coliform. Since the drinking water at the construction site is





pumped from Yudong River, continuous non-compliance of fecal coliform has been detected; however, the results have indicated an improving trend compared to last semi-annual report.

Surface Water: In comparison with Class II of Surface Water Environmental Quality Standard (GB838-2002), only the non-compliance of TN and NH3-N was detected in both September and December 2014 at the dam site, particularly in December, the dry season. According to local environmental monitoring station, it is more related to the high nitrogen baseline level for surface water in Guizhou Province.

Air quality: Fully compliant with Grade II limit of “Environmental Air Quality Standard” (GB3095-1996).

Noise level: Generally compliant with Grade 2 limit of “Acoustic Environmental Quality Standard”.

5.2.2 BAI’ANHE RESERVOIR

In September and December 2014, according to the revised environmental monitoring plan, the water quality at the project site has been tested, and the current water quality was found to be compliant with Class III requirements of “Surface Water Environmental Quality Standard” (GB3838-2002).

5.2.3 LIAOJIUZHAI RESERVOIR*

Since the subproject has been generally completed in September 2014, no environmental monitoring was implemented during this reporting period. With reservoir impoundment in the near future, the environmental monitoring will then follow the environmental monitoring plan for operational phase.

5.2.4 JIANCAOGOU RESERVOIR

In December 2014, the county environmental monitoring station was entrusted to implement the monitoring of air quality, surface water quality and noise level around the project site. The only two non-compliances detected from the monitoring results are the TSP concentration at dam site due to construction activities and the TN level in sampled surface water considering high TN baseline level for surface water in Guizhou Province.

5.2.5 JINJIAQING RESERVOIR

The environmental monitoring of Jinjiaqing Reservoir Subproject was implemented by local environmental monitoring station in September 2014 on surface water quality. Full compliance has been obtained.

5.2.6 JINLONG RESERVOIR

According to the implementation schedule of environmental monitoring for Jinling Reservoir, the next round of environmental monitoring will be carried out in early 2015, whose results will be included in the next semi-annual environmental report.

5.2.7 MAOZHULIN RESERVOIR

The construction of Maozhulin reservoir subproject was suspended until November 2014. Accordingly, the next round of environmental monitoring will be carried out in early 2015, whose results will be included in the next semi-annual environmental report.





5.5. INSTITUTIONAL STRENGTHENING AND ENVIRONMENTAL TRAINING

In August 2014, the environmental consultant has provided project-specific on-the-job environmental training to the individual IAs, contractors and project supervisors for the ongoing Yudongxia, Liaojiuzhai, Jiancaogou, Jinjiaqing, Bai’anhe and Jinlong subprojects to emphasize their respective duties on daily environment management, including implementation of mitigation measures, environmental monitoring, environmental supervision, site inspection and environmental reporting. The scope of training mainly covers the following documents:

- EMP implementation requirements as per ADB loan agreement and project agreement;

- Subproject EMP approved by ADB;

- Environmental Management Rules for Project Construction;

- Implementation of corrective measures taken against earlier detected environmental incompliances.

For Yudongxia and Bai’anhe subproject, special training has been provided on environmental management during the coming project operation.

5.6. ENVIRONMENTAL REPORTING AND SUPERVISION

As presented above, regular environmental supervision has been implemented during the construction of all the ongoing subprojects under GIWRMP.

Following the loan agreement of GIWRMP, GPMO is required to develop and submit the semi-annual environmental report to ADB for review; accordingly, the subproject IAs are submitting the following environmental reports to GPMO at the required deadline:

- Monthly project supervision report (including required section on implemented environmental management) or Monthly Environmental Supervision Reports (for Yudongxia Reservoir Subproject) in the first week of next month;

- Semi-annual environmental monitoring reports for each ongoing subproject for every six months.

With the assistance of environmental consultant, GPMO has formatted the environmental management section of monthly project supervision reports and the semi-annual environmental monitoring reports for subproject IAs to use since July 2013.

This semi-annual report is developed based on subproject environmental reports and relevant documents collected from the IAs by February 2014, as listed in Appendix 1.





6. EVALUATION OF CUMULATIVE IMPACTS AND IMPLEMENTED MITIGATION MEASURES

Under a sector loan modality, GIWRMP has a large number of small subprojects, involving water storage, dam construction, water supply, irrigation, soil and water conservation, flood control and hydropower, which are expected to have low possibility of significant adverse impacts from any one subproject. However, a large number of subprojects to be undertaken in relatively small geographic area in a relatively short period of time may cause significant cumulative impacts, which have been assessed in a general way in the sector EIA (dated Sep. 2006) in compliance with the ADB Environmental Assessment Guidelines (Manila, 2003).

According to the sector EIA, the cumulative impacts of GIWRMP are only expected with the subprojects’ operation based on the actual operation performance/data of implemented subprojects. So far only one subproject has been completed under GIWRMP, namely, Xifeng Small Water Storage Structure Subproject. It is still too early to analyse the resulted cumulative impacts of the project.

During ADB review mission in Nov. 2013, the PMO and mission agreed that it is too early to discuss the details of such assessment, as (i) almost no subprojects are completed, (ii) many subprojects dropped out, and (iii) the confirmed subprojects are far apart and not linked. As such, the assessment will primarily focus on the experiences gained in the project with the design, implementation, and operation of the facilities. The cumulative impacts will be discussed during subsequent semi-annual reports.

However, to facilitate the evaluation of cumulative impacts from GIWRMP implementation, the environmental consultant has assisted the GPMO to start the work with data collection, which includes, but not limited to, the last available version of local water resource management master plans. Once possible, more analysis will be provided on cumulative impacts and implemented mitigation measures of the project.





7. CONCLUSIONS AND RECOMMENDATIONS

7.1. CONCLUSIONS

For GIWRMP, all the implemented investments had strictly followed national and ADB EIA procedures. The required EIA documents (domestic EIA report and SEIA required by ADB) for the new subproject, Hongyan Reservoir, are currently under preparation in compliance with both national and ADB environmental policies. Based on updated project schedule, the domestic EIA report has been approved by the Guiyang Municipal Environmental Protection Bureau in February 2014, the SEIA is expected to be updated and disclosed in March 2015. Considering the 120-day disclosure requirements, ADB may be able to approve the SEIA report in July 2015. The new Hongyan WTP component is classified as a Category B project, which requires domestic EIA report and an English SIEE report prepared in a timely manner to ensure the project completion at the end of reservoir impounding.

During this reporting period, the seven reservoir subprojects under construction, namely, Yudongxia, Bai’anhe, Liaojiuzhai, Jiancaogou, Jinjiaqing, Jinlong and Maozhulin, have been reviewed in terms of their environmental management performance during construction. General speaking, the construction of all the reviewed subprojects has been implemented together with their corresponding EMPs and Environmental Management Rules for Project Construction developed during project preparation in 2009. In accordance with subproject EMPs, the mitigation measures have been implemented to minimize project impacts in terms of noise control, air quality control, wastewater management, water quality protection, solid waste management and ecological protection for construction phase. No major issue has been detected.

The proper implementation of mitigation measures, which will give direct impact to the projects’ environmental performance, is always a key issue tracked and supervised by GPMO. With the assistance of TA environmental consultants, the GPMO has organized the site visits together with environmental consultant to review EMP implementation status of ongoing subprojects in August 2014. With the assistance of environmental consultant, on-the-job environmental training has been provided to the IAs, contractors and project supervisors for six ongoing subprojects (Yudongxia, Liaojiuzhai, Jiancaogou, Jinjiaqing, Bai’anhe and Jinlong) during this reporting period. The formats and requirements of environmental reporting have also been followed by all the stakeholders.

It is notable that continuous environmental improvements have been achieved during this reporting period. Corresponding correction actions will be followed up in the next semi-annual environmental report.

The monitoring results still show a few cases of environmental non-compliance in terms of air quality, surface water quality and drinking water source quality, and the trend of improvements has been noticed even for the still incompliant monitoring results.

For the subprojects in construction phase, by the end of December 2014, there is neither environmental conflict/accident nor any environment complains received from local residents, except for Jiancaogou subproject. The only environmental complaint during this reporting period was received from the villagers living near construction site of Jiancaogou subproject in July 2014 in relation to the impacts of excavation noise at night, which has been immediately and properly addressed by stopping all the construction activities at night.





7.2. RECOMMENDATIONS

Based on the observations during the reporting period, the following observations and recommendations have been made on environmental management of next phase:

(1) Joint efforts of GPMO and environmental consultant have shown positive impacts on continuous improvements of environmental management on the construction sites in terms of implemented mitigation measures, environmental supervision, environmental monitoring and environmental reporting;

(2) With ongoing progress of subproject construction, the assistance tailored to specific progress of each subproject should be provided by GPMO and environmental consultant, for example, on coming impoundment of Yudongxia, Bai’anhe and Liaojiuzhai subprojects;

(3) It is noticed that there were still some non-compliance of environment monitoring results detected during this reporting period, however, the trend of improvements has been observed in these incompliant results, which indicates the effectiveness of corresponding mitigation measures taken by the IAs and contractors. For further improvements, more targeted mitigation measures are needed;

(4) For two new components confirmed after mid-term review, namely Hongyan reservoir and Hongyan WTP, the environmental safeguard documentation will be developed in compliance with both national and ADB requirements. The environmental consultant will work in close collaboration with domestic EIA institute to get the required documents prepared in a timely manner to facilitate the project implementation.

2. SITE VISIT FINDINGS

2.1. JINLONG RESERVOIR IN XIUWEN COUNTY

On Aug. 25th, 2014, the consultant visited the construction site of Jinlong reservoir in Xiuwen County. According to the site conditions and communication with the subproject IA and contractor, currently the ongoing works still focus on the excavation of side slope and flood ditch. Due to lack of counterpart fund and absence of partial construction drawings, it makes reimbursement of ADB loan and blasting and excavation of tunnel impossible.

Overall Construction Site

Excavation of side slope and flood ditch Excavated entrance to diversion tunnel

Side slope on right bank

The key findings during the site visit of Jinlong subproject mainly include :


1） Considering limitation of acquired land and remaining excavation of about 30,000m3, the expansion of spoil area noticed during last site visit remains an urgent issue. Despite great efforts of the subproject IA, it has been confirmed that further acquisition of downstream land is impossible for the expansion of spoil area. Therefore, in consultation with the design institute, it is initially planned to expand based on existing spoil area, and the retaining wall in the original design will be accordingly displaced outwards. The design institute is now justifiying the capacity of spoil area with such expansion and its impacts on downstream river cross section. The detailed design is still under preparation.

Current status of spoil area Initial plan of spoil area expansion

2） The blasting operation will be used in the coming rock excavation for diversion tunnel. According to the site visit, in the collaboration with local professional blasting company, the contractor has implemented necessary safety management measures on the construction site, for example to post safety notice on blasting operation around the site;


Safety notice on blasting operation around the site

3） The first round of environmental monitoring has been implemented in early June 2014 covering the monitoring of surface water quality, air quality and noise level around the project site. The results are compliant with applicable standards. The subproject IA has submitted the first environmental monitoring report for the subproject to Guiyang PMO.

4） In terms of soil erosion, according to the site conditions, after raining season this year, by strengthening soil conservation measures and related monitoring, the soil erosion on the construction site is under good control. Except the excavated area, there is no significant increase of soil erosion.

Side slope in Mar. 2014 Side slope in Aug. 2014

2.2. LIAOJIUZHAI RESERVOIR IN XIFENG COUNTY

In the morning of Aug. 26th, the environmental specialist visited construction site of Liaojiuzhai Reservoir in Xifeng County. Since the beginning of project construction in March 2013, the main dam, including the spillway, has been generally completed. Currently the dam is completing the grouting, and the upstream spillway is under construction. The office building for the reservoir has completed site preparation. Except the spillway, it is expected that the main works (including the office building) will be completed in two months.

bridge

The key findings during the site visit of Liaojiuzhai subproject mainly include :

1） The site visit found that the main ongoing construction activities was dam grouting. The generated wastewater from grouting is diverted into the upstream reservoir area for settling treatment before being discharged downstream.

Treatment of wastewater from grouting

2） It is understood that the subproject IA plans to sow grass seeds over the slope of dam for greening after the completion of main dam.


3） The upstream flood diversion channel as the water source of Liaojiuzhai Reservoir is being constructed as per the design, which is expected to be completed soon. The completed channel will be sufficient to meet the design water storage demand for the reservoir.

Constructed flood diversion channel Flood diversion channel under construction

4） Since most of the land downstream of the reservoir has been changed from original farmland to industrial land, which has reduced the irrigation area targeted by the subproject from the original 1700mu to 100mu, accordingly, the length of irrigation channel included in the project design is accordingly reduced to about 800m, which has been completed and put into use to deliver required flow rate for downstream farmland irrigation.

Gate house and irrigation channel Constructed irrigation channel

5） With the change of land use downstream, in order to sufficiently utilize the original design reservoir capacity, it is initially planned by the subproject IA to add its function to supply human drinking water. A village water treatment plant will be constructed to supply about 2000 residents of nearby Shiqiao Village, which will be financed by local fund. With the change of reservoir function, the environmental specialist urges the subproject IA to further strengthen the monitoring of reservoir water quality, to meet at least Class III surface water quality requirements. In addition, before reservoir impounding (planned in 2016), the reservoir clearing shall be appropriately implemented to avoid any impact on water quality.


2.3. JIANCAOGOU RESERVOIR IN XIFENG COUNTY

In the afternoon of Aug. 26, the environmental specialist visited the construction site of Jiancaogou Reservoir in Xifeng County. Since the commencement of its construction on Dec. 31st, 2013, after addressing the problems of resettlement and access road to the site and the spoil area, now the dam abutment is under excavation. Since there is high-speed railway project ongoing nearby, the method of rock excavation has changed from blasting to normal mechanical excavation. Currently the site excavation is as follows :

Excavation of right dam abutment Excavation of left dam abutment

Currently the 10000m3/d WTP contract has also started site preparation, which is situated on the top of a hill not far away from the reservoir. The water supply from the reservoir will be pumped once and then sent to the WTP. After treatment, the water will supply the low-lying area covering about 2/3 of the urban area in Xifeng County by gravity.

The key findings from site visit of Jiancaogou Reservoir are as follows:

1） Path for villagers: To solve daily traffic problem for the villagers living on the top of hill affected by subproject construction activities, the subproject IA invested 200,000RMB to construct the path for the villagers to the hilltop.

Constructed path for villagers to hilltop to facilitate the daily traffic of the villagers with the investment from

subproject IA

2） Implemented emergency plan for the cutting off of Φ300 water supply pipe: With the

discussion of subproject IA, contractor, construction supervisor and relevant local authorities, for the section of water supply pipe belonging to the county water supply company which has been cut off by dam site excavation, a bypass elbow pipe has been installed to ensure the downstream water use.

Emergency plan for cutting-off of Φ300 water


supply pipe

3） Disposal of spoil soil: According to the site conditions, there still remains high quantities of excavation for dam abutments and foundation. Now part of spoil soil is used for the pavement of temporary road. The remaining spoil soil is transported to the spoil area behind the hill through the access road. According to the site visit, although the river has been dug through and the concern of barrier lake observed during previous excavation has been addressed, the generated spoil soil has affected the river cross section to some extent. The clearance of spoil soil needs to be accelerated, and the site monitoring needs to be strengthened to avoid any new barrier lake.

River cross section at dam excavation site

4） Dam safety: Since the dam location is close to existing railway bridge, ongoing construction of high-speed railway bridge (see the picture below) and urban area of Xifeng County, it is recommended to strengthen the inspection, assessment and monitoring of dam safety during project construction and operation.

Environment of project site

2.4. YUDONGXIA RESERVOIR

On Aug. 28th, together with the representative of subproject IA, the environmental specialist and environmental supervisor visited the sites of WTP under commissioning, reservoir area with impounding, resettlement site and spoil area for Yudongxia subproject. The key findings from site visit are as follows:


1） Water source works: Currently, the impounding of Yudongxia Reservoir has reached the level of 1071.5m, but part of land acquisition for flooded area of the reservoir still remains to be finished. With its completion, the storage water level will soon reach the design level of 1075m. The power house and metallic structure of the power station have been completed and the supply of main equipment has been completed. Part of associated equipment, such as cables, remains to be purchased and installed. The water flow used for power generation in the original design is now directly discharged downstream. Since it is in rainy season, the current discharge flow rate (including that from flushing sluice and power station) is generally high.

2） WTP: The civil works and equipment installation of the WTP have been completed, with about 10% of water supply pipes remaining to be completed. The WTP has been put into commissioning since July with full staffing of operators (about 20 staffs). The current treatment capacity is about 10,000m3/d. The operation is generally good. The lab of the WTP has put into opeartion staffed with 3 technicians. Nine water samples are analyzed everyday for 21 indicators including turbidity, colority, odor, pH, chloride, CODMn, total hardness and NH3-N. According to a copy of weekly report on monitoring results in August, all the water quality indicators are compliant with standard requirements except slightly high residual chlorine. Now the WTP is actively applying for the hygenie license for early water sale.

3） Rehabilitation of spoil area: The environmental specialist visited the original spoil area near auxilliary dam of Yudongxia Reservoir. According to site conditions, the original spoil area has been compacted, leveled and sowed with grass seeds around June 2014. However, due to low earth content in the spoil area, the current growth of grass is not so good. Replanting may be needed as required.

4） Supporting environmental protection measures for resettlement area: Since it was found that the supporting environmental protection measures proposed for resettlemnt site in the subproject EIA had not yet been implemented during last site visit, the environmental specialist visited a resettlement site of Mitangjing during this visit. The resettlement site is a centralized resettlement site constructed based on the willingness of resettled villagers in Mitangjing, consisting of 17 households of resettled villagers. Currently the site is under construction and is expected to be put into use at the end of the year. According to the requirements of subproject EMP, the subproject IA has laid DN90 water supply pipes for the resettlement site, which connects the constructed high-level water tank and water supply station on the top of nearby hill. The water supply station has the treatment capacity of 25m3/d, which is sufficient to meet the water demand of resettlement site; at the same time, the township government will use domestic fund to construct a nearby wastewater treatment plant for the resettlement site for wastewater treatment of the resettlement site.

5） As part of reservoir clearing, the replantation plan of ancient trees updated based on site conditions has been implemented in May 2014. For totally 15 ancient trees in the project-affected area, based on their growth conditions, three have been replanted, four unflooded ones have been protected in situ, and the other eight were cut off since it was impossible to replant them during reservoir clearing. The replantation and protection was implemented under the guidance of local forestry department. After the implementation of ancient tree disposal plan, the results have been inspected and accepted by forestry specialists from the provincial forestry department and Guizhou University. According to the site visit, two of the three replanted ancient trees have survived and the other one has not yet grown with new leaves and branches.

6） Environmental protection approval procedure for project variation : With project variations during its implementation, for example, the addition of power generation system, change of high-level water tank and water distribution pipes and adjustments of dam height and dam top width, in accordance with the requirements of national EIA law, the above-mentioned project variations need to be approved by local environmental protection authority before the inspection and acceptance of environmental protection for project completion. This issue has been clearly raised by the environmental supervisor in the monthly environmetnal supervision report, which is still waiting for the feedback of subproject IA. During the site visit, the environmental specialist requests the subproject IA to send the feedback to Guiyang PMO to update the progress.

7） Progress of inspection and acceptance of environmental protection for project completion: It is understood that, the water source and WTP components of Yudongxia Reservoir will accept the inspection for project completion as a whole. With the completion of remaining works and based on the special inspection and acceptance of soil conservation, the preparation for the inspection and acceptance of environmental protection for project completion will be carried out, which will be expected at the end of this year or early next year.

2.5. BAI’ANHE RESERVOIR IN KAIYANG COUNTY

On Aug. 29th, the environmental specialist visited the construction site of Bai’anhe Reservoir in Kaiyang County. Currently the main dam only has 50cm to be completed, and the water intake will soon be completed. The access road and some grouting works have not yet been completed. In July 2014, the contractor has started the reservoir clearing and the impounding will be in late Sep. or Oct. The inspection and acceptance of environmental protection for project completion will be done at the end of the year. According to the subproject IA, based on current project progress, the subproject is generally within the original budget.

As the main drinking water source for Kaiyang County in the future, the local government pays high attention to the protection of water source for Bai’anhe Reservoir. Currently Bai’anhe Reservoir has almost been completed, and the local water resource bureau and environmental protection bureau have started to jointly implement the original “Plan of drinking water source protection zone for Bai’anhe reservoir of Kaiyang County” (updated in June 2008). The Grade I and Grade II drinking water protection zones have been defined as per the original plan. In the future, its implementation will under joint administration of the county water resource bureau and environmental protection bureau. Kaiyang County used to propose to construct a culture and education zone within the proposed protection zone; however, the proposal has been withdrawn for the protection of water source. Additionally, to support Bai’anhe reservoir, Bai’anhe WTP financed by local government (with the treatment capacity of 10000 m3/d) has almost been completed, which is expected to be put into use together with the reservoir. At the end of project construction, the environmetnal specialist reminded the subproject IA and the contractor to pay special attention to reservoir clearing, site rehabilitation (in particular, the spoil area) and re-vegetation before reservoir impounding which are the focus of envirionemtnal management in next phase. Additionally, the environmental specialist has also reminded the subproject IA to timely switch into the implementation of EMP for operational phase after impounding, in particular, the monitoring of water quality in various cross sections of the reservoir.

In addition, it is understood that, the construction of Maozhulin reservoir in Kaiyang County has been suspended since Jun. 2014 due to resettlement issue and lack of counterpart fund. Recently, 41million RMB loan from the bank of agriculture is in place, resettlement work is also progressing, and the resuming of construction is expected shortly.
