PREFACE The concentration of sulfur dioxide and dust significantly exceeds the standards

during the heating season in Urumqi, which indicates the coal-smoke pollution. According to the “Urban Heating Plan of Urumqi (2006-2020)”, the Urumqi government proposed a centralized space heating system supplied by Cogeneration of Heat and Power (CHP) plants. The government has initiated Urumqi District Heating Project (UDHP) and applied for the World Bank loan. The CHP includes two components:

Component 1: Shayibake District Heating Network Component (SHN) Component 2: Urumqi CHP Shuimogou District Heating Network (UHN) The two components, which are municipal infrastructure projects, are relatively

simple and not related to major physical works. The environmental impacts of such project are limited. According to relevant requirements of domestic environmental impact assessment (EIA), Environmental Impact Forms were prepared for the two components. The two forms were reviewed and approved in 2008 and 2010 respectively (see Table 0.1-1).

In December 2009, The Xinjiang Environmental Technology Consulting

Center (XETCC) was commissioned by the Project Office of Urumqi Heat Reform and Building Energy Efficiency (HRBEE) International Technological Cooperation (POUITC) to prepare two EIA Reports for the components to submit to the World Bank in light of domestic Technical Guidelines of EIA and requirements on EIA in the World Bank safeguard policies.

Being commissioned, The XETCC collected relevant information and investigated the proposed sites and the circumstances of the two components. The XETCC analyzed the project features, construction specifications, scales, technologies, main pollution factors and potential environmental impacts, and composed the “EIA Report for Component 1 of Urumqi District Heating Project: Shayibake District Heating Network Component” and the “EIA Report for Component 2 of Urumqi District Heating Project: Urumqi CHP Shuimogou District Heating Network”. In addition, an EIA Executive Summary was also prepared. This document is the “EIA Report for Component 1 of Urumqi District Heating Project: Shayibake District Heating Network Component”.

The EIA team would like all those agencies for their support and help, including the Xinjiang Department of Environmental Protection (XDEP), the Urumqi Municipal Construction Commission, the Urumqi Municipal Environmental Protection Bureau (UMEPB), the POUITC, the Urumqi Management Office of Heating Industry, the Urumqi District Heating Company (UDHC), EIA teams of the two component, feasibility study teams of the two components and the World Bank China office.

1. INTRODUCTION

1.1 Background

As Urumqi has been experiencing urban expansion, rapid population growth and economic growth in the past decade, industrialization and urbanization have been promoted. In this context, energy consumption would increase significantly. The energy constrains on economic development and energy related environmental issues would become more evident. The concentration of sulfur dioxide and dust significantly exceeds the standards during the heating season in Urumqi, which indicates a typical coal-smoke pollution. The air pollution directly affects human health, traffic safety and sustainable economic development in Urumqi.

According to the “11th Five Year Plan for National Economic and Social Development of China”, the “Medium and Long Term Special Plan of Energy Conservation of China”, the “Urban Heating Plan of Urumqi (2006-2020)”, the Urumqi government took the resource advantages and environmental features of the city into account and proposed a centralized space heating system supplied by Cogeneration of Heat and Power (CHP) plants. Then, the government decided to initiate the Urumqi District Heating Project (UDHP) and applied for the World Bank loan.

When the centralized heating and CHP are implemented as proposed in this project, the energy efficiency would be enhanced and air pollutant emissions would decreases, so that the ambient air quality could be improved, which would help to reach the goal of moderately prosperous society.

1.2 EIA Overview

1.2.1 Objectives of EIA

In accordance with the “Law of the People's Republic of China on Environmental Impact Assessment”, the “Ordinance on Administration for Environmental Protection of Construction Projects”, “Circular about Strengthening the Management of Environmental Impact Assessment for Construction Projects Funded by the International Financial Organizations” and the World Bank Safeguard Policies as well as the procedures of domestic EIA and the World Bank’s EIA, the EIA team of this project assessed and concluded the positive effects of this project, identified, screened, predicted and analyzed the negative impacts, and proposed practical and effective mitigation measures for those inevitable impacts and environmental management plan. This EIA will be submitted to the World Bank and become one of the bases of their independent evaluation of this project. Meanwhile, this EIA will also be the basis of decision-making and integrated management of the government and the environmental management agency.

1.2.2 EIA Category

In light of the “Circular about Strengthening the Management of Environmental Impact Assessment for Construction Projects Funded by the International Financial Organizations” (HuanJian[1993]No. 324) and requirements on EIA in OP4.01 of the


� �

World Bank Safeguard Policies, assessment factors were identified and screened in this EIA. Shayibake District Heating Network Component (herein after “SHN”) pertains to centralized heating energy efficiency retrofitting project, which refers only to renovation, maintenance and updating. Generally speaking, the period of such project is short. Mature and reliable techniques are often applied to such project. The pollutant emissions are easy to control and the affected area is limited. Therefore, domestic EA category for this project assigned by Urumqi Environmental Protection Bureau (EPB) was EA form, which is simpler than EA report. However, according to updated World Bank requirements, a Category A EIA is required for this project.

1.2.3 Preparation of the EIA Report

Being commissioned, the Xinjiang Environmental Technology Consulting Center (XETCC) collected relevant information and investigated the proposed sites and the circumstances of the SHN. The XETCC analyzed the project features, construction specifications, scales, technologies, main pollution factors and potential environmental impacts, and composed the Terms of References (ToR) for the EIA of this project that had been submitted to the World Bank. Then, the “EIA Report for Component 1 of Urumqi District Heating Project: Shayibake District Heating Network Component” was prepared based on the ToR.

1.3 Assessment Scope, Protection Objectives, Period and Key Issues

3. ENVIRONMENTAL AND SOCIETAL BASELINE

3.1 Natural Environment and Environmental Quality

3.1.1 Overview of Natural Environment

3.1.1.1 Geographical Location Both of the two components of the UDHP are located in Urumqi city. Urumqi is

the capital of Xinjiang Uygur Autonomous Region, the center of Eurasia It lies at E 86°37 33 to E88°58 24 and N42°45 32 to 44°08 00 , at the north foot of the midway Tianshan Mountain and the southern edge of Junggar Basin. The city goes in a line covering 14,206km2 with 302.8km2 built up area. In total, seven districts and one county (Tianshan District, Shayibake District, Xinshi District, Toutunhe District, Shuimogou District, Dabacheng District, Midong District and Urumqi County) are governed under Urumqi.

The Sayhagh District is related to component 1: the SHN. The Shayibake District lies in downtown of Urumqi with the area of 427 km2. It goes from Yamlike Hill in the west to Hetan Road in the east and is bordered by Tianshan District. The Shayibake District goes southerward to Wulabo and is bordered by Urumqi County and goes northward to Xinyi Road and is connected with Xinshi District. The LanXin Railway and South and North Xinjiang Railways pass the urban area. The heating area of this project covers the southern area to Urumqi West Bridge, western area to Hetan Road, eastern area to Yamalike Hill and southern area to the special railway of Hongyanchi Power Plant in Shayibake District as well as eastern area to Hetan Road, southern area of Water Park, northern area to the special railway of Hongyanchi Power Plan and western area to Yanan Road in Tianshan District. The covered area is about 17 km2. 3.1.1.2 Topographical Features

Urumqi City is surrounded by mountains. Most regions are located in mountain-plains with an open alluvial plain in the north. The terrain is higher in the southeast than in the northwest. The height of Urumqi is 680-920m with mean altitude of 800m.

The SHN mainly focuses on Shayibake District. Shayibake District lies in the southwest of Urumqi and its northern part is located in the downtown. It is flat in this district. The southern part lies in suburban and hilly area. The south region is higher than the north. The topographical elevation difference is about 100m. The elevation difference of the SHN is significant due to the topographical features. The heat source lies in the south. Its surface elevation is 1,004.1m. The surface elevation of the furthest user is 855m. The elevation difference is 149m. 3.1.1.3 Water Systems

Five water systems lie in Urumqi. They are Urumqi River water system, Toutun River water system, Ziwopu water system, Dabacheng water system and Dongshan water system. The SHN goes across the Heping Canal.

The Urumqi River is a seasonal river. It starts from the No.1 glacier at the southeast of Shengli Daban of Yilinhabierga Mountain, Tianshan Mountain. This river flows from the south to the north, goes out of the mountain pass and joins nine rivers from Nan Mountain and passes alluvial plain in front of the mountain. It then goes through urban area and the plain in the north and flows into Mengjin Reservoir in Miquan. The total length is 160 km. Its annual runoff is 18.2- 29.06 million m3 with


� ��

catchment area of 924km2. The section of Urumqi River in urban area is called Heping Canal. 3.1.1.4 Climate and Weather

Urumqi lies in the center of Eurasia and far from the sea. It falls within the mid-temperate zone arid continental climate zone. The climate features include: hot summer and cold winter with evident weather changes and large temperature difference between the daytime and nighttime. The precipitation is low in Urumqi and shows a vertical increment while the height increases with high evaporation. There are big differences of precipitation among seasons. Inversion layer can be detected in winter. The prevailing wind direction is northwest, which is significantly affected by Tianshan Mountain. Mountain and valley wind is obvious. Days with calm wind is prevailing in winter. When it is sunny, the wind direction is south in the night, which is mountain wind while north wind blows in the day, which is valley wind. Heavy wind blows when season changes to spring or autumn. The annual frequency of temperature inversion is high in Urumqi due to the terrain. Particularly in heating season, the temperature inversion lasts long and features strong and thick with low mixed layer. In short, the atmospheric diffusion condition is extremely bad combined with dry air, low precipitation and less precipitation days. The air purification ability of Urumqi is weak. Thus, the weather conditions make air pollution serious, particularly during the long weather.

The climate parameters of Urumqi are listed in Table 3.1-1.

3.1.1.5 Soil and Vegetation

The original soil type of Urumqi is grey desert soil, which pertains to alluvial soil plain by the Urumqi River. The soil layer is thick with light salinization. The surface of most areas in the built up region is hardened road and artificial green belt. The soil type of suburban areas is grey desert soil. The vegetation mainly includes low and sparse drought-tolerant plants. The main plants are seriphidium borotalense and nanophyton erinaceum. Salsola, ceratocarpus and other ephemeral plants can also be found. The vegetation cover is about 10%.

The heating pipeline network of the SHN will be laid along the special railway and existing civil roads. Green belts that are 2-3m wide lie at both sides of Yuyuan Road, Saimachang Road, Heilongjiang Road and Qitai Road. The pressure-isolated


� ��

heat exchange station will take use of existing boiler room (Lantian Boiler Room), so no new land acquisition will happen. 3.1.1.6 Animals

Most of the works of the SHN will be carried out in the built up area of the city. Minority parts will be constructed in suburban areas. Types of animals in these areas are simple, with few wild animals. Main animals in these areas are companied by human beings. Most of them are resident birds and breeding birds. The dominant species of birds in suburban areas are sparrows, horned larks and larks. Mammals are rare in this region. Only rodents like house mouse (mus musculus) are often seen. There is no rare or endangered species.

3.1.2 Surface Water Quality

The pipeline of the SHN is proposed to pass across the Heping Canal. In the investigation of water quality, data and information were collected to evaluate the surface water quality baseline of the Heping Canal. The regular monitoring results of the Heping Canal Power Supply section and the Gaojiahu Bridge section provided by the Central Environmental Monitoring Station of Urumqi in August 2009 were cited in this report. Figure 3.1-1 shows the monitoring points.

(1) Monitoring items In light of the environmental situations where the project is located, 22 items for

water quality monitoring were selected, including pH, DO, permanganate value, CODcr, BOD5, NH3-N, volatile phenol, oil pollutant, Hg, Pb, As, Cd, Cr(+6), cyanide, fluoride, sulfide, TP, TN, Zn, Se, Anionic surfactant and fecal coliform.

(2) Assessment standards Category V in the “Environmental Quality Standard for Surface Water”

(GB3838-2002) is based for surface water of the Heping Canal according to its function (agricultural irrigation). The standards are listed in Table 3.1-2.

Figure 3.1-1 Number of Days When the Ambient Air Quality Meets the Standard (2001-

2009) It can be seen in Figure 3.1-1 that the number of days when the ambient air

quality meets the standard significantly increased from 2001 to 2003 since scattered small boilers were replaced by large-scale heating in Urumqi. The number did not change much from 2003 to 2009, which indicates that the effect of centralized heating on improving the ambient air quality of Urumqi become weak. It is necessary to replace existing centralized heating with CHP in order to further improve the ambient air quality.

3.1.3.2 Current Status of Ambient Air Quality in 2009

(1) General situation The general situation of ambient air quality of Urumqi in 2009 is shown in Table

3.1-4. The comparison between air pollutant concentrations during the heating season and non-heating season is presented in Table 3.1-5.

Heating season of 2009

0.159 1.65 0.202 1.02 0.085 0.06

In 2009, the annual average concentration of SO2 is 0.093 mg/m3 which is 0.55

times higher than Grade II in national air quality standard. The annual average concentration of PM10 is 0.14 mg/m3 which is 0.4 times higher than Grade II standard. The annual average concentration of NO2 is 0.0685 mg/m3 which is close to Grade II standard. The coal-fired sources contribute more than 90% of SO2 and 60% of PM10 in Urumqi. It shows a typical coal-smoke pollution.

In the heating season in winter, the emission inventory of SO2 accounts for more than 2/3 of annual total. Given the frequency of calm wind and temperature inversion is higher than 90%, the air pollution shows seasonal changes. The pollution appears light in spring and summer and goes serious in autumn and winter. Extreme pollution sometimes happens in winter. In the heating season in 2009, the concentration of SO2 was as high as 0.180 mg/m3, which is two times higher than Grade II in national air quality standard. The monthly concentration of PM10 was 0.199 mg/m3, which is 0.99 times higher than Grade II in national air quality standard. The heaviest pollution happened in January.

(2) Monitoring results of regular monitoring points in 2009 Only the counterpart works like pipeline network and heat exchange stations will

be constructed in the SHN, but not the heat source plants and boilers. Thus, there will be no issues of pollutant emission in this project. In this context, data and information were collected in this EIA to analyze the ambient air quality. Regular monitoring data by the Central Environmental Monitoring Station of Urumqi was cited as the information of current status in the project region.

This report cites ambient air quality monitoring data of regular monitoring points, including Urumqi Railway Bureau, Monitoring Station and Toll Station from March 21st to 27th, 2009, provided by Urumqi Environmental Monitoring Station, and the monitoring data of six monitoring points, including Government of Shuimogou District, Jianfang Group, Hongqiao Peak balancing Boiler Room, Xuefeng Civil Exploder Company, Xinjiang Center for Disease Control and Prevention (CDC) and Training Center for Civil Servants from December 18th to 24th, 2009, provided by the Central Monitoring Station of Urumqi. The monitoring items are PM10, SO2 and NO2.

Single pollution index is applied to assess the air quality. It was calculated as: Pi = Ci/C0 Where Pi represents single pollution index; Ci represents the monitored

concentration of pollutant (mg/m3); and C0 represents the value of assessment standard (GB3095-96).

The assessment results in Table 3.1-7 show that the concentrations at nine

monitoring points all exceeded the standards. Among others, the concentration of PM10 exceeded the most at every point. The proportion of days when the monitored concentrations was beyond the standard ranges from 28.6% to 100%. The highest concentration of PM10 was 6.69 times higher than the standard. SO2 was the second. The proportion of days when the monitored concentrations was beyond the standard ranges from 14.2% to 85.7%. The highest concentration of SO2 was 0.17 times higher than the standard. The concentrations of NO2 were not beyond the standard. The ambient air quality in the assessment area could not meet the Grade II in the “Ambient Air Quality Standard” during the monitoring period. The primary pollutant is PM10 and the secondary one is SO2, which indicates a typical coal-smoke pollution. The main reason of the excess is the pollutant emissions from coal in winter. In addition, the topographical and meteorological conditions also cause the bad air quality in the heating season.

3.1.3.3 Conclusions

As discussed above, the coal-smoke pollution happens in winter in Urumqi. The monitoring results in the whole city provided by the Central Monitoring Station of Urumqi indicate obvious regional differences of air pollution among areas. The monitored concentrations of pollutants are much higher at the central area of the city (south region, south of Hong Hill) that in the north region of Hong Hill. In terms of period distribution, big differences between the heating season and non-heating season can be detected, particularly for SO2 and PM10. The concentrations of the two items can meet the Grade II standard in non-heating season while they are much higher than the standards in heating season.

3.1.4 Acoustic Environmental Quality

Several measures were implemented in Urumqi in 2009 to supervise traffic noise, noise of city life, construction noise and industrial noise. Industrial noise was required controlled before deadline. Sound barriers were set along key road sections so that the disturbance of traffic noise on residents has been relieved. The control and management of noise from restaurants and noise during the university entrance examination were improved. In 2009, the average equivalent sound level of traffic


� ��

noise was 70.1 dB(A) that is 1.1 dB(A) lower than the last year. The regional average equivalent sound level was 54.9 dB(A) that pertains to “Less Good” Grade.

The main noise sources in the region that the SHN relates to are traffic noise. In order to assess the acoustic environmental baseline in the project region, the Xinjiang Monitoring Station was commissioned in March 2010 to carry out noise monitoring at the boiler rooms related to the SHN, proposed pressure-isolated heat exchange stations and residential areas along the pipeline network.

According to the “Noise Zoning of Urumqi On the Basis of ‘Standard of Environmental Noise of Urban Area’” promulgated by the UMEPB, Category 4a in the “Environmental quality standards for noise” (GB3096-2008) is based for sensitive points like residential areas, schools and hospitals along trunk roads. Most of the heating pipeline network of the SHN will be laid along trunk roads, so Category 4a in the “Environmental quality standards for noise” (GB3096-2008) is based for these areas. Category 2 standards are based for rural areas where the pipelines pass. The pressure-isolated heat exchange station of the SHN will be renovated from Lantian Boiler Room. Category 2 in the “Emission Standard for Industrial Enterprises Noise at Boundary” (GB12348-2008) is based for the station boundary. The monitoring methods were applied as required in the “Environmental quality standards for noise” (GB3096-2008). The monitoring instrument was noise analyzer AWA6218A-1 and calibration instrument was sound level calibrator ND-9.

In light of the project features and potential impacts of the SHN, ten sensitive points along the project, Lantian Boiler Room (that will be renovated to pressure-isolated heat exchange station) and Water Park Substation were selected as monitoring pointes. The monitoring results are shown in Table 3.1-8 and Table 3.1-9.

The gross industrial output value in this district was RMB 11.926 billion Yuan with increase rate of 13.0%. The fixed assert investment was RMB 5.214 billion Yuan with increase rate of 8.2%. The budgetary revenue of local government was RMB 1.035 billion Yuan with increase of 1.07%. Total retail sales of social consumer goods were RMB 12.517 billion Yuan with increase rate of 9.19%. 3.2.2 Energy Structure Coal is the main energy source in Urumqi, accounting for about 90% of total energy use. The consumption of coal in the heating season is more than 4 million ton, accounting for more than 44% of total energy use in winter. The coal consumption per capita is about 3.96 ton, which is ranked first around the cities in China and is 4 times of the national average level. The percentage of coal to final energy consumption decreased 10%, from 55.5% in 1998 to 10.1% in 2004, while the percentage of natural gas increased from 6.6% in 1998 to 10.1% in 2004. Although the proportion of coal


� ��

went down, the total amount of coal use has risen with GDP year by year. The energy consumption and energy mix of Urumqi are presented in Table 3.2-3.

Table 3.2-3 Energy Consumption and Energy Structure of Urumqi Indicator Unit Consumption Proportion (%)

The proportion of natural gas in primary energy of Urumqi use was only 3.7% in 2009. According to the “12th Fiver-year Plan for Energy Consumption Structure of Urumqi” and “Urban Heating Structure Adjustment Plan”, the natural gas heating will account for 33.33% of total heating.

3.3 Current Air Pollution Control and Management

3.3.1 Air Pollution and Its Causes in Urumqi

In Urumqi, the area of thermal- power cogeneration and clean energy heating currently accounts only for 20% of the total area. The rest are supplied through centralized heating or scattered coal-fired heating. Table 3.3-1 shows the current status of heating in urban areas of Urumqi.

Clean energy Total

13. 55.94 8.46 13.83 6.50 97.73

As statistics shows, there are 178 coal-fired boilers in 52 centralized heating

boiler rooms, 790 coal-fired boilers in 369 scattered heating boiler rooms and 9297 scattered small civil coal stoves. There are only 23% of centralized coal-fired boiler rooms, from which the dust emission can meet the air pollutant emission standard. The proportion for SO2 emission is 12%. No desulfurization and dust removal facilities are installed on scattered small boilers. The low efficiency, high energy consumption of boilers and low efficiency of desulfurization facilities causes that the days when air quality can meet the standard accounts for less than 50%. Accordingly, annual average air quality can not meet the standard. Thus, the vital tasks in Urumqi are to manage scattered coal-fired boilers and adjust energy structure. In this context, it becomes an emergent task to develop centralized heating through CHP, so that the efficiency of energy use could be improved; energy saving and pollutant emission reducing could be promoted; and the environmental quality could be improved.

In light of current situations of energy supply and heating in Urumqi, the government proposes to improve centralized heating through CHP, to develop clean energy heating like gas heating and to promote energy saving strategy of heating. The proportion of CHP and clean energy use is proposed to reach 90% until 2015.


� ��

The main reasons of heavy air pollution in Urumqi except the natural geographic conditions are discussed as below.

(1) The primary man-made causes of air pollution in Urumqi are improper

energy structure and high energy consumption The primary causes of air pollution in winter in Urumqi are the coal-based

energy structure and low energy efficiency and waste. Currently, coal accounts for more than 70% of total primary energy consumption in Urumqi. The coal consumption per capita is ranked first among cities in China and is 4 times of national average level. In 2008, total coal consumption was 14.72 million ton, 2/3 of which was used in winter. The energy sources of main pollution sources including power industry, construction materials industry, metallurgical industry and heating industry are coal-based. The high pollutant emissions are due to high energy consumption. The pollutant emission inventory is over the environmental capacity. The coal consumption by sector is listed in Table 3.3-2. The air pollutant emissions are shown by sector in Table 3.3-3.

Table 3.3-3 Air Pollutant Emissions by Sector in Urumqi (2007)


� ��

Table 3.2-2 and Table 3.2-3 explain the improper energy structure of Urumqi.

The natural gas and renewable energy account for less than 5% of total primary energy consumption. The big users of coal are power sector, construction material industry, chemical industry, metallurgical industry and heating sector. The coal consumption in these sectors accounts for 96% of the total use in the city. The pollution emissions from these sectors also accounts for most of the emission inventory of the city. SO2 emission was 1.35 million ton, account for 91.8% of the inventory of Urumqi. NOx emission was account for 73.9% and dust emission accounts for 72.6%. SO2 emission from life sources accounts for 8.1% and dust from life sources accounts for 27.4%.

(2) The air pollution is exacerbated due to the dominant coal-fired heating There are 178 large coal-fired boilers in 47 boiler rooms distributed in the center

of Urumqi city. There is one centralized heat supply station in per area of 2.7 km2 in average. In addition, thousands of civil coal-fired boilers or stoves exist in peri-urban areas. The scattered distribution and fragmented heating mode make the air pollution in heating season in Urumqi is exacerbated.

According to statistics, unadvanced desulfurization facilities are used in most centralized heating boilers. Even no desulfurization facility has been installed in some boilers. Thus, the pollutant emissions can not meet the standards. The concentration of dust emission of only 23% of the boilers can meet the local standard (100mg/m3 for Period I) in the “Emission Standard of Air Pollutants for Coal-fired Boiler” (DB65/2154-2010). The concentration of SO2 emission of only 12% of the boilers can meet the local standard (500mg/m3 for Period I). Since the thermal efficiency and chimney of scattered boilers are low without desulfurization facilities, it is more obvious that the dust and SO2 emissions are beyond the standards. All of these aggravate the air pollution in winter in Urumqi.

At present, the area of CHP accounts for 13.68% of total heating area in Urumqi. The area of clean energy heating like natural gas heating accounts for 6.83%. The area of centralized heating accounts for 72%. The rest are scattered heating with small boilers. The heating structure is improper, because on the one hand, the CHP has developed slowly and can not satisfy the rapid increase of new heating areas, which have to depend on expansion of centralized heating stations and scattered boilers.

the other hand, it is because that part of CHP and scattered boilers within the centralized heating area have not been integrated in the centralized heating network for some reasons.

The Southern District Heating Network Project and Weihuliang Power Plant CHP Project were carried out in 2007. About 150 scattered boilers and 2200 small coal-fired boilers have been replaced by CHP. The annual coal consumption has been reduced 90,000 ton. The annual reductions of SO2, dust and cinder are 1420 ton, 4080 ton and 18,000 ton respectively.

(3) Low direct emission from non-point life sources like scattered boilers and small coal-fired boilers cause severe pollution.

Because there are not proper environmental protection devices in scattered boilers and small coal-fired boilers, the desulfurization efficiency is low and emissions are much over the standards. Their impacts on air pollution in winter in Urumqi are significant and should not be ignored. The results of “The Research of Causes of Air Pollution in Urumqi” conduced by Tsinghua University indicates that in terms of contribution to pollutant concentrations, the non-point life sources and heating boilers less than 20 ton have major effects on concentrations of main pollutants. Low direct emissions from non-point life sources like scattered boilers and small coal-fired boilers contribute about 40% of the concentrations of SO2, PM10 and NOx in heating season. Thus, it is crucial to manage the low non-point sources. In the coming period, an important task of air quality improvement in Urumqi is to integrate scattered small coal-fired boilers into centralized heating network or transform them to gas boilers.

(4) Industrial production lies in low level of the industrial chain. The economic growth is extensive. The situation that air pollutant emissions from industrial sources are beyond the standards is still serious. Emission inventory caused by coal firing is significantly high.

In 2008, the emission inventories of SO2 and dust were 140,000 ton and 63,000 ton respectively. The emissions from industrial sources dominated the inventory, which accounts for 91.9% of SO2 emission and 71% of dust emission. The emission by sector focused on power and thermal production and supply sector, petroleum processing and coking industry and ferrous metal smelting and rolling processing industry. The accumulated equivalent emission load of these sectors reached 85% in 2008.

The key pollution sources in Urumqi contribute much to air pollution. The air pollutant emissions in Urumqi concentrate on nine factories, the equivalent emission load of which accounts for 80-90% of the total equivalent emission load of all key industrial pollution sources. 40% of SO2 emission inventory comes from the power sector.

The industries that promote rapid economic growth in Urumqi are featured as high resource input and consumption and high pollutant emission, including petrochemical, steel, power, coal and building materials industries, etc. Currently, unadvanced technologies are applied in the production of these industries. The production lies in low level of the industrial chain with low added-value. That is why the resource consumption and pollutant emissions per production are much higher than international and domestic advanced levels. In 2007, the energy consumption per


� ��

GDP was 2.54 ton standard coal per 10,000 Yuan RMB in Urumqi, which is 2.2 times of the national average level. The SO2 and dust emission inventories per industrial added-value were 0.054 ton per 10,000 Yuan RMB and 0.025 ton per 10,000 Yuan RMB respectively, which are 2 times of the national average level.

High energy consumption leads to high emission. High emission leads to serious pollution. According to the general survey of pollution sources, more than 80% of dust and SO2 emissions come from industrial factories, which focus on power production plant, large-scale industrial factories and centralized heating factories. SO2 emissions from the top 20 factories (see Table 3.3-3) accounts for 74% of the total emission inventory. Among others, SO2 emissions from Huandian Xinjiang Hongyanchi Power Corporation, Guodian Xinjiang Hongyanchi Power Corporation, Huadian Xinjiang Weihuliang Power Corporation account for 40%. To date, only Huadian Xinjiang Weihuliang Power Corporation and Hongyanchi Power Corporation have installed desulfurization facilities. Guodian Honyanchi Power Co. Ltd. initiated large power generators and reduced small generators. However, there are still 4 small generators running. SO2 emissions from China National Petroleum Corporation Urumqi Branch, Baosteel Group Bayi Iron & Steel Corporation, Shenhua Coal Gangue Power Plant, Tianshan Cement Corporation and XinJiang XinHua Chemical Fertilizers Ltd. accounts for 23%. The contribution of dust emissions from these factories is also high. The pollution prevention and control of many centralized heating corporations like Guanghui Thermal Corporation is weak. 40% of emissions from these factories exceed the standards. SO2 emissions accounts for about 20% of total emission inventory in Urumqi.

(5) The contribution of vehicle emissions to air pollution increases year by year.

Given the rapid urban development and increase of vehicle population, pollutant like NOx emissions keep increasing. The pollution condition for “photochemical smog” exists in some places. The coal-smoke pollution has not yet been managed. If it is added with vehicle emissions, compound pollution may happen. This would have major impacts on ambient air quality in Urumqi. To date, the vehicle population in Urumqi is 280,000 vehicles, which refers to registered ones. About 850,000 vehicles increased in three years from 2006 to 2008, while 70,000 new vehicles were registered in 2009. There are currently more than 100 vehicles registered every day. The annual increase rate of vehicle population is higher than 15%. Table 3.3-4 shows the changes of vehicles in Urumqi from 1997 to 2009.

Table 3.3-4 Changes of Vehicles from 1997�2009 Year Vehicle population (vehicle) Annual increase rate (%) 1997 43865 2000 66588 51.80 2004 126145 89.44 2005 138488 9.78 2006 152411 10.05 2007 177148 16.23 2008 210000 18.54 2009 280000 33.33


� ��

The vehicle emissions in built up areas contribute about 40.1% of NOx and 94.1% of CO in total air pollutants. In recent years, the concentration of NO2 in ambient air keeps rising and exceeds the standard in heating seasons. The annual average concentration of NO2 is close to national standard, which should be paid attention to.

3.3.2 Current Air Pollution Control and Management

According to the First General National Survey of Pollution Sources, the emission inventories of SO2 and dust (including industrial dust) were 140,000 ton and 63,000 ton respectively in 2008. As calculated, the environmental capacity of SO2 and dust of Urumqi is about 67,400 ton per year and 63,000 ton per year respectively. The emission inventories are far over the environmental capacity and have aggravated the air pollution in Urumqi.

In order to control air pollution in winter, a “Leading Committee of Urumqi for Air Pollution Control in Winter” was established. The “Leading Committee” is responsible for annual examination of air pollution prevention and control and task decomposition at each period. They are also responsible for supervising and examining if the air pollution control objectives are reached in each period.

In order to control air pollution caused by coal firing in winter, the implementation of the “Emission Standard of Air Pollutants for Coal-fired Boiler” (DB65/2154-2010) has started since 2010. The emission concentrations of dust and SO2 required in this standard is lower than the requirements in the “Emission Standard of Air Pollutants for Boilers” (GB13271-2001).

Since the “Blue Sky Project” was initiated in 1998, the air quality of Urumqi has significantly improved from traditional heating through scattered coal-fired boilers to centralized heating through large coal-fired boilers, and then to current heating through CHP. There were 262 days when the air quality meets Grade II standard and better than Grade II in 2009, while there were only 149 days in 1998. However, the air pollution in winter is still affected by the energy structure and topographic features. The days when the air quality can meet the standards account for less than 50% in heating seasons in winter. This has become an obstacle to socio-economic development of Urumqi.

The energy consumption structure and mode have changed a lot through a series of key projects and environmental management measures. The use of clean energy needs to be further promoted in the future. The scattered coal-fired boilers in urban areas shall be integrated into the centralized heating network. Large-scale CHP shall be implemented. Air pollution control of key pollution sources shall be strengthened to improve the environmental achievements. Furthermore, industrial distribution and structure needs to be further optimized to control air pollutant emissions inventory. It is proposed to control SO2 emission inventory less than 67,000 ton per year and dust emission inventory less than 40,000 ton per year, in order to achieve air quality objectives.

3.4 Respiratory Disease Status

As reported by the World Health Organization in 1998, Urumqi was ranked the fourth in Global Top 10 polluted cities. In 2004, Urumqi was the fourth city with most serious air pollution among 47 key cities in China. There were 25 days when Grade V air pollution happened in Urumqi in the winter of 2006. It was 10 days in 2009. Seasonal air pollution is obvious in Urumqi, which focuses on heating season in winter. The severe air pollution has affected residents’ health and living level.

Air pollution does much harm to human health. The common harm is respiratory diseases and physiological dysfunction. In addition, people often get sick because mucosal tissues like eyes and noses are irritated. The harm of air pollution to human health is listed in Table 3.4-1.

Table 3.4-1 Harm of Air pollution to Human Health Pollutant Harm to human health

SO2 Causing respiratory diseases, exacerbating cardiovascular disease, and reducing

lung resistance

O3 Reducing lung function and causing airway inflammation, chest tightness, cough

and nausea NOX Irritating the lung and reducing its resistance to infection

Particles Affecting breathing and causing lung tissue damage, cancer, and premature CO Weakening the ability of blood to carry oxygen

According to epidemiological research, air pollution closely relates to the

number of outpatients of respiratory disease and cardiovascular disease as well as the lung cancer mortality. The research indicates the direct relation among the incidence of respiratory disease, air pollution and meteorological conditions. The incidence of respiratory disease increases when serious air pollution happens. Referencing the research conducted by Wang Yan etc. (The Effect of Air Pollution in Urumqi on the Respiratory System Diseases, Journal Of Shenyang Agricultural University(Social Sciences Edition), 2007-10, 9(5), 783-785), the respiratory outpatients of some hospital in Urumqi in years are cited in Table 3.4-2.

2079 1476 1549 1926 1701 1545 1506 1778 1758 1669 2220 2179

As analyzed in the above table, the number of respiratory outpatients shows the following characteristics:

(1) Respiratory disease happens every month but varies significantly among seasons. The number of respiratory outpatients reached the peak in November, December and January. Except for factors like weather change, pressure increase and sudden drop of temperature, air pollution in heating season in winter is the main cause of the increased incidences of respiratory disease in Urumqi.


� ��

(2) Due to urban expansion and increase of urban population, the energy consumption is more intense. Consequently, the intensity of air pollution emission increases, which leads to the significant increase of respiratory patients.

(3) Respiratory outpatients decrease in spring and summer with good air quality.

3.5 Key Environmentally Sensitive and Social Protection Areas

3.5.1 Current Status of Cultural Heritages

In the field investigation, the EIA team identified two mosques in the project area, including West Bridge Mosque and Hetian II Street Shayibake Mosque. The two mosques are general religious sites but not cultural heritage. Local custom needs to be respected when the construction is carried out in this section. The workers need to understand ethnic customs and taboos in order to avoid disturbances on ethnic minorities’ life and culture. 3.5.1.1 West Bridge Mosque The West Bridge Mosque lies close to Youhao South Road. There exists a pavement in the north which is connected to Xibei Road and Youhao South Road. It is about 15m wide and 60m long. The traffic is busy in this area. There are also many pedestrians around. More than 1,000 people visit the mosque on Friday Prayers. There are usually 100-200 visitors. 3.5.1.2 Shayibake Mosque Shayibake Mosque is a Uygur mosque located near Hetian Street. It was built in 1947. There are usually 60-70 visitors. The number of visitors that come to the mosque on Friday is 100-200.

3.5.2 Ecologically Sensitive Areas

4. ENVIRONMENTAL IMPACT ASSESSMENT

4.1 Impact Assessment during the Construction Phase

4.1.1 Ecological Impact Assessment during the Construction Phase

(1) Impact of new land acquisition on ecological environment The pipeline of the SHN will be laid along existing special railway of power

plant and civil roads. Existing boiler room (Lantian Boiler Room) will be taken use as pressure-isolated station. Thus, this project will not lead to new land acquisition. Temporary land acquisition is needed for pipeline laying. The width of the works will be about 10m. Temporary land acquisition of construction is about 3,332 m2. The impacts on vegetation induced by the temporary land acquisition happen in the year of construction. The vegetation can be recovered after the construction.

(2) Impacts on vegetation and woodland The works of the SHN pertains to linear construction. Its impacts on vegetation

are mainly due to pipeline works. The main impacts include tree transplanting and lawn removal.

The natural vegetation is sparse in the project region. Artificial vegetation lies in green belts at both sides of roads and woodland affiliated to organizations along the project. Common trees include white ash tree, ulmaceae, ulmus densa, cloves, torch tree and c.ovata, etc.

Some of the trees along the project will be transplanted. During the process, the vegetation cover ratio will decrease in a period. However, the green belt will be recovered after the construction is completed. Construction dust will affect the plant growth, but the works is limited in this project. Thus, the impact of dust on vegetation during the earthwork excavation is minor and will become weak after the construction is completed. Watering during the construction phase can minimize the impacts of dust in order to protect the plants. In addition, solid waste like residual soil from trench excavation and domestic waste will also have impact on the plants. At the construction sites, the residual soil will inevitably fall on the plants and impede respiration and photosynthesis in leaves.

Additional impacts on the vegetation include damages to the root and skin of remained trees due to incautious human or machinery working. However, such impacts can be controlled.

(3) Impacts on wildlife Among original animals in the project region, the density of rodents is relatively

high. Small rodents are common, e.g. house mouse (mus musculus) and cricetulus. Main birds include sparrows, barn swallows and larks. The construction may destroy their habitats and affect some individuals. However, the impacts on their communities are not major because of the large population and strong ability to adapt to changes of these two kinds of animals.

4.1.2 Acoustic Environment Assessment during the Construction Phase

(1) Noise sources The main noise sources of the SHN during the construction include construction

machinery and transport vehicles. Different machinery will be applied in different stages. In the SHN, excavator will be used for trench excavation; vehicles will transport pipelines during the pipeline laying; welding machines and generators will


� ��

be used for pipeline welding; crane will be utilized for pipeline laying and bulldozer will be used for backfill. All of these works will be carried out in daytime. The machines will be alternately applied and their positions will change as the construction goes on.

In this EIA, references about equipment selected in similar constructions were analyzed. In light of the analogical analysis and field investigation, machines as noise sources that cause noise higher than 85 dB(A) were identified, including excavator, crane, welding machine, bulldozer, concrete mixer, cutting machine and transport vehicles. They are listed in Table 4.2-1.

Table 4.1-1 Noise Intensity of main construction machines Unit: dB A No. Noise source Noise intensity No. Noise source Noise intensity 1 Excavator 92 5 Concrete mixer 95

2 Crane 88 6 Concrete dump

truck 90

3 Welding machine 85 7 Cutting machine 95 4 Bulldozer 90

(2) Noise prediction model When the sound source is much smaller than the prediction distance, the sound

source can be seen as point source. The noise of the sound source attenuates as the distance increases. It is calculated as the following formula:

1

212 r

r20lgLL

Where r1 and r2 are distances to the sound source (m); L1 and L2 represent the

noise levels at the points, the distances of which to the sound source are r1 and r2. (3) Results of noise prediction There are usually several different machines working at the same time in the

sites. Their sound levels will be added. The added-value depends on the type, quantity and distribution of noise sources. Table 4.2-2 shows how the construction noise attenuates as the distance increases.

Table 4.1-2 The Attenuation of Construction Noise Unit: dB A Distance (m) 10 20 40 80 100 200 400 800 1000

Excavator 80 74 68 62 60 54 48 42 40 Crane 76 70 64 58 56 50 44 38 36

Welding machine 73 67 61 55 53 47 41 35 33 Bulldozer 78 72 66 60 58 52 46 40 38

Concrete mixer 83 77 71 65 63 57 51 45 43 Concrete dump truck 78 72 66 60 58 52 46 40 38

Cutting machine 83 77 71 65 63 57 51 45 43 (4) Noise impacts during the construction phase The excavator will be used for a long period during the pipeline construction of

the SHN. The noise intensity of such works is high and lasts long. Other machines, like concrete vibrating rod, concrete mixer, concrete dump truck, cutting machine and bulldozer can be operated intermittently, the noise of which lasts short. Thus, noise of excavators reflects the noise impacts of pipeline works.

This EIA considers the excavators as representative noise sources during the Construction phase. As calculated, the noise level of excavators along the pipeline attenuates as the distance from both sides of the pipeline increases. The noise level ls lower than 54dB(A) at the point 200m away from the sound source. According to the


� ��

field investigation, many residential communities are located less than 200m away from the pipeline of the SHN. The noise sensitive points are listed in Table 3.5-1. The nearest community is about 10m away. It is confirmed that the acoustic environment of these points will be affected by the construction noise. The increases of noise level will be different at different points. It will be over the standard at the residential areas that are close to the pipelines. However, the construction noise is temporary and the noise sources are scattered. In addition, the construction is usually carried out in daytime. Acoustic environment will not be influenced at nights. Therefore, the impacts of construction noise on surrounding residents are not major.

4.1.3 Air Pollution Impact Assessment during the Construction Phase

The air pollution sources of the SHN include construction dust and construction machinery exhaust. The impacts of construction dust are relatively significant. 4.1.3.1 Dust impacts during the construction phase

The construction dust mainly comes from earthwork excavation, stacking, backfill and transportation. The dust generation and its impacts depend on the season, construction management and meteorological factors like wind force, etc. The dust impacts get severe if it is dry and windy.

As analogized, under normal meteorological conditions with while mean wind speed of 2.6m/s, the features of construction dust on site are: the TSP concentration at the construction site is 1.5-2.3 times of that at the control point upwind. The TSP concentration at the point 150m downwind from the dust point in the construction site can reach about 0.49 mg/m3, which is 1.6 times of the air quality standard.

Excavators and transport vehicles are most used during the pipeline construction. The dust due to earthwork excavation and the secondary dust due to transportation along the line will influence the air quality. The dust caused by backfill could also have impacts at the site and increase the TSP concentration. Table 4.1-3 presents the impacts and scope of dust influence of pipeline construction while the wind speed is equal to or higher than 3.5m/s and the relative humidity is equal to or lower than 60%.

Table 4.1-3 Dust Impact and its Scope of Pipeline Construction Distance to the sites m 5 20 30 50 100-150 Dust concentration mg/m3 10.14 2.89 1.15 0.86 0.61

According to relevant research, dust generated by vehicles accounts for 60%

total dust, the dust inventory and the pollution are closely related to mode of transport, road conditions and meteorological conditions, etc. The areas 150-300m away may be affected, in different situations. If watering the road 4-5 times per day during the construction phase, 70% of the dust can be reduced. The radius of area affected by TSP pollution can be reduced to 20-50m. The most used vehicles in this project will be heavy ones transporting pipelines, excavators and cranes, so construction site management should be implemented well to avoid dust pollution. Watering at sites shall be considered. The watering frequency and volume could be determined according to the real case. The construction shall be forbidden when heavy wind blows. 4.1.3.2 Impacts of vehicle exhaust emissions

Construction machinery exhaust emissions refer to exhaust from fuel machinery and transport vehicles. Main pollutants include CO, NOx and hydrocarbons (CnHm), etc. The exhaust emissions are temporally and spatially focused. The concentration is high in a local area. Construction machinery like excavators and heavy trucks, etc. would enter in the construction site. As the Ministry of Transport measured and


� ��

calculated, the CO concentration of heavy truck is 37.23 g/km· vehicle; the NOx concentration is 10.80 g/km· vehicle; and the CnHm concentration is 16.83 g/km· vehicle. The machinery exhaust is unorganized non-point source, which would have negative impacts on the ambient air in the project area. However, such impacts that last not long will disappear while the construction is completed.

4.1.4 Water Environment Impact Assessment during the Construction Phase

(1) Impacts of Pipeline passing the water body Jacked and overhead pipeline of the SHN will be used when it goes through the

Heping Channel. The construction will not have impacts on the water environment. (2) Domestic wastewater Most of the works of this project will be carried out in urban areas. No temporary

living facilities will be set. Local houses would be rented. The domestic wastewater is discharged into the municipal drainage.

(3) Construction and pressure test wastewater During the construction, construction wastewater includes muddy water at the

construction site, water at site, possible leak at nodes where new pipeline connects with old ones and wastewater generated from pressure test. The wastewater mainly contains suspended solid and slurries. The physical and chemical properties of the wastewater are similar with original water. It pertains to clean wastewater and is not harmful to soil environment. There will be about 10000 m3 wastewater generated from pressure test every day, which can be used for greening. The volume of rest wastewater is low as long as existing heating pipeline would not be damaged and water would not leak. The impact of wastewater will have minor impacts on the environment as it naturally evaporates and infiltrates. No vehicle wash place will be set in the SHN. Construction machinery including vehicles will be cleaned in local car wash.

4.1.5 Assessment of Solid Waste during the Construction Phase

Solid wastes generated during the construction phase of the SHN include residual soil, construction waste and domestic waste.

The residual soil is generated from trench excavation and site leveling of pressure-isolated heat exchange station and substations, etc. The residual soil is non-toxic solid waste. The leakage of soil during the transportation and disposal would have impacts on the environment. It would affect city’s visual appearance if the soil storage is not orderly due to vague disposal location.

The construction wastes mainly include heat insulation materials and packaging materials of equipment and disable gray sand, concrete, broken bricks and rubble, building materials and processing waste at pressure-isolated heat exchange station and substations. If the waste could not be disposed in time, it would not only have visual influence, but also generate dust in windy and dry days.

Domestic waste comes from staff living within the construction site. Un-orderly disposal of domestic waste would lead to breeding of mosquitoes and flies, which may make surrounding residents affected by mosquitoes, flies, odor and diseases.

According to the feasibility study of this project, earthwork balance would be implemented well during the construction. The disposal of excavated earthwork will


� ��

be: � being backfilled for heating pipeline and site leveling; � being transported to landfills nearby; � being used in greening.

The construction waste shall be piled at designated sites in light of the requirements of “Administration Measures of Urumqi on Urban Construction Waste” and transported to the operating Urumqi Construction Waste Landfill.

The domestic waste shall be piled at designated sites and transported to the Urumqi Landfill every day. Therefore, the solid waste during the construction phase will not have impact on the environment.

4.1.6 Social Impact Assessment during the Construction Phase

According to the field investigation, the SHN does not relate to resettlement issues. The project region is ethnic minority region. A special team has been commissioned to prepare the ethnic minority program. Thus, major social impacts during the construction phase refer to negative ones on people’s travel and traffic during the pipeline construction. 4.1.6.1 Impacts on Residents’ Travel

The pipeline network of the SHN concentrates on road sections where commercial activities are busy and many residential areas are located. There are many sensitive points along the pipeline network. There are 32 residential areas, four schools and one hospital at the 200m regions away from the heating pipelines. According to questionnaire investigation, the most common way for the residents to travel is taking bus. The less common ways include walking, driving, taking taxi and taking corporations’/institutions’ bus.

As the pipeline of this project will be laid along the roads, the impacts on residents’ travel is comprehensive. The key impacts are on the travels to working. Other travels, like shopping, children going to school and going to the hospital will also be affected. People that often go to the mosque are mainly old men. The affected population is relatively small, but impacts on individuals are significant. However, such inevitable impacts on residents’ life will last short and will stop as the construction is completed. 4.1.6.2 Impacts on Traffic

The pipeline network will pass some busy road sections. For example, the DN1200 L1 pipeline network of the SHN will pass the special railway of Hongyanchi Power Plan when it goes out of the power plant. The pipeline will be laid along the north side of the railway to the west area. When it enters in Shayibake District, the pipeline needs to go 50m across Hetan Express Road. The Hetan Express Road is an important channel going from north to south of Urumqi. The L2 pipeline network will go eastward along Yining Road Changjiang Road Heilongjiang Road Baoshan Road Youhao Road and Qitai Road and then diverge. The two L1 pipelines will converge at Yanerwo Road. In addition, Huanghe Road, Zhujiang Road and Cangfanggou Road are also arterial roads. Some of road sections are narrow where the impacts of pipeline construction may become more significant. Thus, the pipeline works will have major impacts on the traffic along the project. 4.16.3 Impacts on Public Transport

One of the impacts of pipeline construction on the public transport is the loss of passengers. The distance between stops increases, so the income of the Bus Company would decrease. Consequently, staff’s income would be influenced. The other impact is that the passengers would spend more time on the way to bus stops. It is also inconvenient for passengers if the bus stops and routes are changed.


� ��

4.1.6.4 Impacts on coach stations Nianzigou Coach Station and South Suburban Coach Station are two big stations

in Urumqi. The buses travel to the north and south Xinjiang. It is busy in the station and there are many passengers. The pipelines will pass the roads surrounding the coach stations.

Road excavation near coach stations will have two aspects of impacts. First, it will be inconvenient for passengers to enter in or go out of the stations. Second, it is hard to solve the issues about luggage transportation. The direct economic loss would reach 10%. 4.1.6.5 Impacts on Ethical Culture and Cultural Heritages According to the field investigation, two mosques lie in Xibei Road and Hetian II Street along the SHN. These mosques are general religious sites but not cultural heritage. Local culture should be respected during the construction. No cultural heritage was found along the project. However, the project goes through the old Urumqi, it is probable to find underground culture heritage. Thus, the construction should be stopped once culture relics is detected and this should be reported to environmental protection staff at the site. The environmental protection staff is responsible for protecting the site and informing the cultural heritage agencies that will cope with the issue. 4.1.6.6 Impacts on students’ travel Some sections of the pipeline network will go along the roads where students go to school. Some sections will go through the gate of schools. The impacts on schools include: (1) it is inconvenient for students to walk or take bus when they go to and off school; (2) the students would need to spend more time on the way; (3) safety issues would become significant because of traffic jam and un-orderly traffic.

4.2 Impact Assessment during the Operation Phase

4.2.1 Acoustic Environment Assessment during the Operation Phase

Noise sources during the operation phase of the SHN include the pressure-isolated heat exchange station and substations. The pipeline would not cause noise impact. The acoustic wave would attenuate when it goes through the buildings in which the pressure-isolated heat exchange station, substations and peak balancing boilers are set. The acoustic wave would reach the prediction point after noise attenuation by distance, sound barriers and air absorption. The attenuation factors also include rain, snow, fog and temperature gradient, etc. Thus, the real noise attenuation in sound transmission process is higher than the predicted attenuation. That is, the predicted noise level is higher than real value at each prediction point. The acoustic impact is predicted as the following formula:

Where, T represents calculation time for equivalent sound level; N represents the number of outdoor sound sources; and M represents number of equivalent outdoor sound sources.

The noise of the SHN mainly comes from the pressure-isolated heat exchange station and substations. When they are operating, they would have impacts on surrounding environmentally sensitive points. As for Lantian pressure-isolated heat exchange station, circulating water pump and make-up constant pressure pump are main noise sources. The noise is acceptable as long as the following measures are implemented. The measures include reasonable siting and construction of pressure-isolated heat exchange station, selecting low-speed and low-noise circulating water pumps, replacing traditional valve with variable-speed control device and setting damping base for equipment. The sound insulation effects of windows and doors should also be considered. Thus, noise nuisance could be avoided. The noise impact of substations on the environment is minor. The sound level of operating pump and make-up pump is lower than 80dB(A). The noise of substations is calculated as the attenuation of a 80dB(A) sound source. The sound level attenuates to 50dB(A) in an area with radius of 10m due to the wall. The sound level can meet the standard of Category II function zone in the “Emission Standard for Industrial Enterprises Noise at Boundary” (GB12348-2008). As new stations are all located in communities, they can not be built within the area with radius of 40m from sensitive buildings in order to alleviate the impacts of noise and vibration on residential buildings. According to land occupation of the proposed substations, they can satisfy the requirements about the attenuation distances. Thus, the substations will have minor impacts on the acoustic environment.

4.2.2 Assessment of Waste Gas during the Operation Phase

The SHN mainly contains heating pipeline and substation projects. During normal operation, as plate heat exchanger will be applied and hot water will be running in a closed system, no air pollutant will be generated. Thus, impacts of waste gas during the operation phase are not assessed in this EIA.

4.2.3 Assessment of Wastewater during the Operation Phase

Waste water from the substations of the SHN is mainly back wash water of softened water treatment equipment. According to experiences, the discharge volume from each substation ranges from 120 m3 to 180 m3 every year. According to analogical analysis of monitoring data of water discharged from existing urban community with heat exchanger, the concentrations of pollution factors are as following: pH 8.1, SS 44mg/L, BOD5 4.55 mg/L and CODcr 22.5 mg/L. It pertains to clean wastewater. The wastewater, which meets the “Discharge standard for municipal wastewater” (CJ3082-1999), can be discharged into municipal drainage directly and would not cause environmental pollution.

To conclude, wastewater from substations of the SHN can meet discharge standards and will not cause water pollution.


� ��

4.2.4 Assessment of Solid Waste during the Operation Phase

During the operation phase of the SHN, the solid waste is mainly domestic waste of staff in the pressure-isolated heat exchange station and substations. The staffing is 302 persons. If it is calculated as 1.0 kg domestic waste per person every day, about 110.23 ton domestic waste will be discharged every year during the operation phase. Un-orderly disposal of domestic waste will lead to breeding of mosquitoes and flies, which may make surrounding residents affected by flies, odor and diseases.

4.2.5 Environmental Risk Analysis during the Operation Phase

(1) Types of environmental risks According to experiences, the primary accident risk of heating network is

pipeline explosion during the operation. The explosion would lead to leakage of hot water that flows into green belts and makes the plants scalded or burned. Such accident may cause damages to ecological environment. In addition, as large volume of hot water effuses from the underground, it may burn people on the street. This would also waste water resources, pollute water environment, bother people’s travel and affect scenes of the city.

Another risk of heating network comes from checking wells along the pipeline. The wells are normally closed. Seeper and organics inevitably exist in the wells. They may generate toxic and harmful gases like H2S by microorganisms. The concentration would get high due to poor ventilation and long-term accumulation, so the maintenance men may get poisoned.

(2) Causes of accident risks The surface elevation of the Hongyanchi Power Plan is 994.5m while the surface

elevation of the farthest user is 851.5m. The elevation difference between the lowest and highest points is 143m, so the network security with high elevation difference becomes an issue. It is analyzed as below:

� The hydrostatic pressure at the node where the point with high surface elevation switches to the low point is high. Strong resistance to pressure of equipment is required.

� Water hammer may be caused by abnormal operation like pump being suddenly stopped and valve being closed too fast.

(3) Prevention measures According to the above analyses, the emergent measures are proposed as below: a) Once the accident happens, principals of relevant agencies should implement

measures and organize the rescue in light of specified emergency plan. They should also report the accident to relevant local authorities and environmental department. The agencies should get to the accident site once they are informed.

b) The management agency should lead and direct the rescue in light of specified emergency plan. Necessary measures should be carried out to reduce the lost.

c) Heating control valve should be closed once leaking or explosion accident happens. The hot water shall be led to the nearest well cellar so that it would not go into green belts. The pipeline should be repaired immediately. In addition, check and


� ��

maintenance of heating pipeline network should be strengthened to avoid such accident.

d) When it is definitely unable to control the accident, the principals should report to relevant upper departments and ask for backup as soon as possible. Members in the command headquarter must get to the accident site and conduct rescue immediately.

e) As for possible damages of checking wells to maintenance men, they should detect the air in the wells to ensure the security before getting down into the well. At the same time, some people should stay on the ground, who shall rescue the colleague down in the well to prevent casualties once abnormal situation happens.

4.3 Cumulative impacts of the two components

Under the combined heating between the CHP plant and the peak balancing boiler room, the thermal power plant located outside the downtown area will provide stable basic heat load. When the outdoor temperature goes down beyond the capability of the basic load provided by the CHP plant, the peak balancing boiler room located inside the downtown area will be actuated for heating. Thus, the peak balancing boiler room will run a shorter time in the heating season than when the boiler room supplies heat separately. Thereby, the coal consumption and pollutant emissions will be reduced. In addition, the 100m high chimney in the thermal power plant is higher than the 50m high chimney in the boiler room. Advanced techniques and high-efficiency desulfurization and denitration equipment is utilized in the thermal power plant so that the high-efficiency centralized control and high-altitude emissions of air pollutants replaces the low-efficiency scattered control and low-altitude emissions. It is in accordance with national environmental policies. This project could improve air quality, make remarkable environmental benefits, improve the investment environment and promote local economic development.

4.3.1 Emission Reduction after the Implementation of the SHN

implemented, the concentrations of SO2, NO2 and PM10 can be decreased thus can meet Grade II standards in the “Ambient Air Quality Standard” (GB3095-1996) and its revised lists. The ambient air quality of Urumqi will be significantly improved.

4.4 Induced impacts

As a result of the project, some small boilers are to be replaced by the project DH network and will be closed according to the city government’s policy. Some of them will be kept as back-up for emergencies. Most of them will be demolished sooner or later in the future. This constitutes indirect impacts induced by the project.

4.4.1 Closure of Boilers

About 11 centralized boiler houses(having 42 boilers) and 20 smaller boiler rooms (having 45 boilers) will be closed in the SHN, total about 87 boilers., The EA team conducted survey of asbestos in the 11 larger centralized boiler houses (Table 8.2-1) which shows 14 boilers of them contain asbestos. The 45 smaller boilers were built before 2000 thus mostly contain asbestos materials. Therefore, total number of boilers that might contain asbestos is about 59 in the SHN component.

4.4.2 Environmental impacts of boilers dismantlement

Environmental problems caused by boiler dismantlement mainly include: (1) Dust in the construction phase Dust in the construction phase mainly come from the dismantlement of boiler

equipment and chimney. Cleaning and transporting soils and dust on-site would also cause dust pollution.

(2) Wastes from site clean-up Wastes like broken bricks and rubble and old boiler equipment would be

generated in the process of site clean. If they are not disposed in time, visual appearance would be influenced. Dust would be caused in windy and dry days.

(3) Asbestos pollution of small boilers demolition The asbestos is used for temperature insulation outside the boilers and pipelines,

which can enhance the heat efficiency of boilers and reduce heat loss. According to site investigation, asbestos materials are used in boilers that started running before 2000, while they are not utilized in boilers that started running after 2000.

Asbestos is listed in the “National Hazardous Waste Inventory”, the type of

which is HW36. Its code is 900-032-36. Asbestos materials would be unpackaged during the dismantlement of small boilers. The asbestos fibers would be released and float in the air for a long time and might be inhaled by human. Although asbestos is definitely identified as a carcinogen, it would only damage human health when its concentration in the air reaches a significant level. The impact of asbestos is minor as long as it is stored and disposed properly.

5.3.3 Feedbacks from Meetings

5.3.3.1 Affected corporations that need to be integrated into the heating network (1) Issue: the corporations that need to be integrated into the proposed heating

network hoped their employees could be properly arranged. (2) Response: The project owner has proposed several ways to cope with the

corporations that need to be integrated into the proposed heating network, including: (a) big corporation being acquired by the UDHC; (b) merger of state-owned property and the UDHC; (c) boilers that need to be integrated into the proposed heating network being rebuilt to public substations. The ways to arrange employees include: (a) this employees in state-owned corporation and institutions will be arranged by the corporations and institutions themselves. No employee can be left jobless. (b) The UDHC could hire regular staff in the centralized heating corporation that are excellent after the examination. 5.3.3.2 Users in the heating network integration areas

(1) Issue: the main concern of the users in the heating network integration areas is the heating service after the network integration.


� ��

(2) Response: the heating service could be guaranteed by corporation with strong producing and service capacity. The users can enjoy high-quality heating service with moderate price. The state-owned corporation takes more social responsibilities. The heating for low-income groups it is difficult for whom to pay for the heating fees can be guaranteed. The environment of areas where individual-owned buildings are focused can be improved. The quality of residents’ life can also be significantly improved. 5.3.3.3 Citizens traveling during the pipeline construction

(1) Issue: the main concern of citizens that will travel during the construction phase is the possible traffic congestion that may cause nuisance to normal life or work of the residents, organizations, schools and corporations. The schools hoped the construction could be carried out in holidays to reduce impacts on students when they go to or off school. The coach station hoped surrounding constructions might be carried out from April to July before school holidays to avoid traveling peak when college students go back home. Based on their needs, business men in the markets hoped the constructions near the markets could avoid tourism peak from July to September.

(2) Response: The construction period shall be shortened to reduce disturbances. The road would be recovered as soon as possible. In particular, traffic accidents and injuries due to road excavation should be prevented.

5.4 Conclusions of Public Consultation

The EIA team interviewed affected corporations, residents in the project region and the project owner and management agencies of the SHN and got the public’s attitude to, comments on and suggestions to this project. To conclude, the corporation, staff and residents had all known about this project. They were looking forward to it and thinking it was an important approach to improve air quality of Urumqi. Individual life and health would benefit from this project as well, so they could understand the negative impacts on their life and work. They hoped the government and the project owner could concern more about citizens’ interests, shorten construction period, and recover the road as soon as possible. In particular, traffic accidents and injuries due to road excavation should be prevented. Responding to the public consultation, the UDHC composed the bilingual “Convenience Guide of the SHN” (in Chinese and Uygur), which explains issues that needs to be paid attention to during the construction. The guide also informs the residents with traffic management plan, traffic control, by-pass routes, time and positions. The information was announced via media in advance. It aims to minimize negative impacts of the construction through the above measures. Meanwhile, the “Circular about Strengthening the Protective Measures of Disposing Hazardous Materials like Asbestos During the Dismantlement of Boilers” and the booklets titled “The Damage and Disposal of Asbestos” were delivered to the construction units by the POUITC in order to enhance the awareness of construction units and the owners of the boiler rooms.

6. ANALYSIS OF ALTERNATIVES

6.1 Alternatives of “With” and “Without” Project

The analysis of “without” project alternatives is environmental baseline analysis. It analyzes the development trends of regional environment and environmental issues related to the proposed industry if the proposed project would not be carried out. Coal-smoke air pollution appears in Urumqi, particularly in winter. One of the reasons is the special geographic and meteorological conditions. Another reason is high energy consumption of the industries and civil organizations due to backward technology. In addition, low-price coal is consumed with regardless of cost for coal resource is abundant in Urumqi. Many coal-fired pollutants have been discharged in the air. This is the main factor that exacerbates the air pollution. As this project is implemented, about 117,440 ton standard coal can be saved; 9,157 ton SO2, 3,574 ton dust and 325,600 ton CO2 emissions can be reduced every year. This means large volume of air pollutant emissions will be reduced, which will improve the air quality in Urumqi.

The UDHP can gradually reduce pollutant emissions from the boilers and save much energy. It is beneficial for air pollution prevention and energy saving.

6.2 Alternatives of Project Locations

6.2.1 Layout of the pressure-isolated heat exchange station

The key functions of pressure-isolated heat exchange station are: (1) to isolate the exposure of parts of the pipeline and the substations to the

hydrostatic pressure resulted from the land elevation difference; (2) to separate the transmission pipeline network from the transmission/

distribution network and to reduce the pressure of the transmission pipeline network; (3) to reduce the dynamic hydraulic fluctuation in accidents and to prevent the

obstruction from water hammer. Existing Lantian Heat Supply Station will be used as pressure-isolated heat

exchange station, so layout alternatives are not discussed in this report.

6.2.2 Layout of the substations

The substations should be set based on the following principles: (1) Indirect connection would be applied to substations which could make the

operation, adjustment and maintenance convenient. (2) Existing boilers would be utilized as much as possible to reduce the

rebuilding of L2 and L3 network. (3) Small boiler rooms that are close to each other shall be incorporated and

rebuilt to substations. (4) The new substations shall be located at the load center to reduce the length of

L2 network and to save investment and operating cost.


� ��

(5) New substations should not be too large or too small. The scale shall be controlled in the range of 30,000- 200,000 Yuan RMB/m2.

(6) Short-term and long term constructions shall be considered at the same time.

6.2.3 Layout of the heating pipelines

6.2.3.1 Layout principles of heating network

The trunk pipeline of heating network shall be designed based on the following principles.

(1) It should be tried to lay the trunk pipeline through the load center. The pipeline shall be reduced as much as possible while the users are satisfied.

(2) The pipeline shall be laid along the roads so that it is convenient for future construction and maintenance.

(3) The pipeline shall be set at areas where less resettlement is needed to save project investment.

(4) The pipeline shall be laid in flat areas to avoid height fluctuation.

6.2.3.2 Laying of heating pipeline network

The heating pipeline network can be laid in three ways: directly buried, in pipe trenches or overhead.

In the directly buried way, the pipelines are laid underground so they are not exposed to external factors or it rarely get damaged. In the case of leakage, the harm to people and the environment is limited. However, it is difficult to detect the leak point. Although the construction period is short and cost is low, the earthwork volume would be large. The highest temperature of the temperature insulation materials of directly buried pipelines is 135oC.

In pipeline trenches (including pipeline jacking) way, the pipeline network is laid underground, so it is not exposed to external factors or it rarely gets damaged. In the case of leakage, the harm to people and the environment is limited. It is easy to find out and repair the leak point. As it is buried underground, volume of earthwork is large. The construction period is longer and higher cost is needed.

In overhead way, the pipeline network is exposed to external factors and easy to be damaged. In the case of leakage, it is harmful to people and the environment. However, it is easy to check and repair in this way. The pipelines occupy large space and affect the city’s visual appearance. Earthwork excavation is less with longer construction period and lower investment.

Considering the safety of the network operation, the buried network was selected on the basis of the parameters of the heating network, the routing and direction of the network and the city’s visual appearance. As the temperature of water in L1 network is 140� at the first stage and will be raised to 150� at the second stage, the pipeline of L1 heating network from the thermal power plant to the pressure-isolated heat exchange station will be buried in trenches. As the temperature of water in pipeline from thermal power plant to L1 heating network and in L2 network from pressure-isolated heat exchange station to users’ substations is 130�, directly buried way will be mainly applied and the pipeline trenches (including pipeline jacking) will be applied in some sections.


� ��

Special treatment will be made to the pipeline that runs across important road intersections or road sections where it is unsuitable for excavation (e.g., when it runs across riverside rapid roads or railways, etc.). Shallowly buried and excavated way is recommended for the pipelines with radius more than DN1000. Pipeline jacking is recommended for those with radius less than DN1000.

6.3 Alternatives of Technology and Techniques

Through decade efforts on air pollution control in Urumqi, the heating technology has developed from heating by scattered coal-fired boiler rooms to centralized heating by large coal-fired boiler rooms and to centralized heating by CHP. The advantages and disadvantages of these three technologies are discussed in Table 6.3-1.

Table 6.3-1 Comparison of Different Heating Technologies No. Technology Advantage Disadvantage

1

Heating by scattered coal-

fired boiler rooms

Low investment and operation cost; easy management and

maintenance

The boiler rooms are randomly built in urban areas. The pollution sources are scattered with small scale, which is not good for air pollution control. The energy efficiency is the lowest. Pollutant emissions can not meet the

standards.

2

Centralized heating by large coal-fired boiler

rooms

Large-scale boiler room with high energy efficiency;

High techniques can be applied to air pollution control

The boiler rooms are built in urban areas. There are a lot of pipeline

constructions. The pollutant emissions are possible unable to

meet the standards through terminal control of air pollution.

3 Centralized heating by

CHP

Energy efficiency is higher than thermal power plan and heating respectively. The air pollutant emissions per heating area are the lowest. The scale effect makes air pollution control more economic. It is easier to meet the emission standards. The CHP will be built outside the built up areas.

The investment and cost are high. The requirements on management

are strict.

As discussed in the above table, air pollutant emissions could be gradually

reduced by developing centralized heating through CHP. The air pollution could be alleviated and the energy could be saved with low energy consumption. According to the requirements in the “Forbidden Zones and Strict Management Zones of firing high-pollution fuels”, both new and expanded coal-fired boilers are forbidden in the forbidden zones of firing high-pollution fuels since 2010.


� ��

6.4 Alternatives of Heating Fuels

Given the coal-based energy structure of Urumqi, natural gas accounts for only 3.7% of primary energy consumption. The increase rate of gas use is 25%-30% due to the rapid urban development. However, the gap of gas supply in summer and winter are 0.2 million m3 and 1 million m3. The reasons include: (1) gas supply is insufficient; (2) seasonal differences of consumption are obvious; and (3) it is hard for upstream gas supply companies to balance seasonal different demand. In order to guarantee living gas, measures like controlling gas heating in new communities and gas vehicles, and constraining normal production of factories that needs natural gas as input, have to be implemented.

In August 2009, China National Petroleum Corporation emergently initiated Northern Xinjiang Gas Supply Component of the Project of Natural Gas Transmission from West to East China Line 2. This component is proposed to be completed at the end of 2010. It is planned to supply 6.6 billion m3 gas to northern Xinjiang, 3 billion m3 of which will be supplied to Urumqi. The problem about gas gaps in Urumqi could be resolved. It is crucial to optimization of energy structure and environmental protection.

In this EIA, it is assumed that annual supply of 3 billion m3 natural gas from Northern Xinjiang Gas Supply Component of the Project of Natural Gas Transmission from West to East China Line 2 is reliable. In addition, several gas sources are available for Urumqi. And the coal gas project will be implemented. In this context, the gas supply is predicted to reach 5 billion m3 in 2015. The proportion of gas to primary energy consumption will be 11.2%. The rate of gas use of urban residents will be 100%. The gas heating will account for 45%.

Table 6.4-1 and Table6.4-2 present some of the indicators cited from “12th Five

Year Plan of Energy Consumption Structure of Urumqi” and “Urban Heating Structure Adjustment Plan of Urumqi”.

7.5 Reporting Mechanisms

The PMO (POUITC) will be responsible for collecting environmental monitoring reports and environmental supervision reports, and prepare the Monitoring and Evaluation (M&E) report about the EMP implementation to the World Bank every half year.

The contracted environmental monitoring unit/agency will submit the monitoring reports and data to the POUITC in time after the monitoring tasks are completed. The monitoring reports will include the analyses for monitoring data, e.g. if it meets the standards, and the causes why it does not meet the standards, etc.

The “M&E Report for EMP implementation” could include the following: • The implementation of the EMP, e.g. training progress, the implementation of

measures proposed to modify those problems from the previous time and their effectiveness, etc.

• The project progress, e.g. the length of laid pipeline network, etc. • The implementation of environmental protection measures, environmental

monitoring and main monitoring results as well as problems and their causes. • If there is environmental complaint, the contents of complaint, the causes

analyzed, solutions and the public satisfaction will be recorded and included in the report.

• Action plan for the next half year, including measures to correct problems found.

7.6 Closure plan for small boilers

(1) Institutional arrangement for boiler dismantlement According to the “Circular about Approving and Forwarding the

‘Implementation Plan for Urumqi CHP Network Integration’ ” (Wuzhengban [2010] No.127), management organizations of boiler dismantlement are mainly Urumqi’s each district governments and district environmental protection bureaus. Their respective responsibilities include:

• The UMCC is responsible for comprehensive planning of coal-fired boiler

dismantlement within the covering area of each CHP, composing annual program, coordination, supervision and management.

• The district governments are responsible for organizing the implementation of coal-fired boiler dismantlement within their authorized district. They are also responsible for dismantling the boiler rooms and the affiliated equipment.

• District environmental protection bureaus are responsible for sending notices about modification for network integration within a time limit to boiler rooms in the proposed integration area. The notices would order the boiler rooms to carry out boiler dismantlement within a time limit.

Since most of these small boilers are beyond the control of the PMO and UDHC, their demolition will need to be overseen by the third party. According to the domestic


� ��

institutional arrangement in China and that in Urumqi, the municipal government and EPB as well as the concerned district governments and EPBs will be responsible for supervising and monitoring the demolition process to ensure it is conducted in an environmentally sound manner and that any hazardous wastes (such as asbestos) from the demolition are handled and disposed of properly. The PMO has sent an official letter, viz. the “Letter about Proper Disposal of Wastes Generated from Dismantlement of Small Boilers” to the UMCC, which suggested the environmental protection measures be implemented in the process of dismantlement of small boilers and be supervised by the UMEPB.

(2) Environmental impact mitigation measures for boiler dismantlement The measures for proper handling of boiler dismantlement and disposal of wastes

are listed in Table 7.6. For those small boilers owned by the UDHC, UDHC will be responsible for implementing measures in the closure plan when demolishing the boilers and the PMO will supervise. For those small boilers owned by others, the owners will implement the closure plan and the Urumqi governments and the EPBs will be responsible for supervision, as stated in the section above.

7.7 Management plans to address social impacts

The project entity contracted an experienced local social to conduct social analysis to the project area. Through broad participations of project stakeholders, project information dissemination, public consultations, interviews, focus group of discussions, and quantity of data information analysis, the social analysis concluded that there will not be direct impacts to land acquisition and structure demolition caused by Bank supported project and the all communities fully supported the project. The social analysis also prioritized the stakeholders concerns that were identified as indirect impacts, were concentrated on three major issues. These issues were suggested to be minimized or mitigated as the disturbance to city traffic during project civil work, workers in small closure boilers that might be dismantled during the project implementation or later and heating price influence to the vulnerable families. It is important to ensure the success in the project program of small boiler closure and the avoidance of enterprise workers’ income reduction, the avoidance of the influence to vulnerable families, and the enhancement of city traffic management and emergency management (i.e. in the unlikely event of water pipeline break, a cut in electricity during pipeline installation) during project construction period. Based on the informative social analysis, the PMO prepared the stand-alone impact analysis to the vulnerable people and the monitoring plan, the monitoring plan for the workers in the closure boiler stations, traffic management plan, and emergency management plan. 7.7.1 Traffic Management Plan This Bank supported second levels of heating transferring pipeline will be constructed along main city roads with about 55 km in two districts in Urumqi city. The construction period of each section (street block) will take one or one and half of


� ��

month. It is really challengeable to manage the project well and implement the targeted tasks on time. The earthwork could be only carried out in half of a year from April to October since the earthworks are restricted by cold weather in winter season and interrupted by rainy summer season. The project management plan takes mitigation measures to enhance the project management and the earthwork implementation. However, citizens were experienced in the daily traffic facts and had their concerns to the traffic disturbances. In order to manage a better project from different perspectives, the project authority contracted an experienced local social consulting team to conduct the social analysis by participatory approaches in 41 engaged urban communities and prepared a traffic management plan and monitoring plan to the traffic management. The project authority will assign full-time staff to be the executive manager in the field as the head of monitoring team. This team will be grouped in the construction sites by local social specialists, representatives of the communities/schools/mosques/hospitals/ owners of shops/enterprises, local traffic policemen and volunteers in the districts. The sections of the constructed roads will be sealed by fences and notices including the project information, hot-line, supervisors and contractors, will be pasted on. The social specialists will collect the information from daily traffic, citizens complains and report to the project authority and the project leading group consisting of executive Major and Head of municipal traffic management office. A quarterly traffic monitoring report will be sent to the Bank. For emergency manner as the unlikely event of water pipeline break, a cut in electricity during pipeline installation, any citizen could call to the project leading group. The hot line and booklets will be disseminated in each community and pasted on the community information walls. 7.7.2 Monitoring plan for workers affected by small closure boilers The concerns of the workers affected by small boiler disclosure were addressed by the project authority. A monitoring plan was prepared to monitoring the implementation of municipal policy that indicates zero laid-off workers if the factories/enterprises are closed down by reasons. The monitoring teams will be grouped by local social specialist, representatives of the workers in the small boilers and the staff from the project authority. Yearly monitoring will be reported to the Bank and their findings would be reported directly to the project authority even upper to the project leading group. 7.7.3Heating assistance plan to low income families Based on the information analyzed by the local social team, some of the low income families did not pay much attentions to the heating price increase since Urumqi launched a program to support the low income families with the policy of no extra charge to those families for years, but some of the low income families were getting worried to the heating price and the negative change of the municipal policy. The project authority prepared a monitoring plan as heating assistance plan to low income


� ��

families. The monitoring team will consist of local social specialist, the representatives of the communities/low income families and staff from project entity. Yearly monitoring report focusing on no extra charge to those low income families will be sent to the Bank and project entity. Urumqi municipality will afford to the increase of the heating price through municipal budget as it is implemented currently.

8.1.1 Current Status of Heat Sources

Hongyanchi CHP is coal-fired using pulverized boilers for power and steam generation. It is using electrostatic precipitators (ESP) for removal of dust and particulate matters and wet lime scrubbing for flue gas desulfurization. Hongyanchi CHP is expansion of the older plant on the same site. One of the two expanded boiler units has been in operation since September 2010 while the other has not. The on-line monitoring system for the plant shows that flue gas emissions have been compliant with national and local emission standards as well as with the WB/IFC Environmental Health and Safety (EHS) guidelines.

Boilers at Lanzhu and Shiyue boiler houses are coal-fired with some boilers being

fluidized-bed and others being chain boilers. These boilers used to use water scrubbing or fewer stages of ESP for de-dusting and simple alkali for desulfurization. Their stack

emissions could not meet emission standards before retrofit. The progress of the heat sources are shown in Table 8.1-1.

8.1.2 Air Emissions From 2009 to 2010, the air pollutant emissions of the peak balancing boiler did not meet the local standards in the “Emission Standard of Air Pollutants for Coal-fired Boiler” (DB65/2154-2010) of Xinjiang. The emissions were a little higher than the standards. According to the “Notice about Air Pollution Control of Corporations including Xinjiang Xinlian Thermal Co. Ltd. within a Time Limit” (Wuzhengtong[2010]No.29) promulgated on March. 29th 2010, 20 involved corporations needed to control the air pollution within 2010. The boiler room owners should actively organize the controlling tasks. The main air pollutants like SO2 and dust should meet the emission standards (viz. SO2 150 mg/m3 and dust 50mg/m3) through installing electrostatic precipitator, bag precipitator and isolated high-efficiency FGD equipment, etc. The efficiency of electrostatic precipitator should not be lower than 99%. The desulfurization efficiency should not be lower than 80%. Shiyue Boiler Room and Lanzhu Boiler Room are both included in the 20 corporations that needed to control the air pollution and to complete the rectification by the end of 2010.

No. 1, No. 2 and No. 3 boilers in the Shiyue Boiler Room are 29MW chain

boilers. Ceramic multi-tube precipitator and wet FGD equipment were applied. No. 3 boiler in the Lanzhu Boiler Room is a 29MW chain boiler. No. 5 boiler is a 58MW circulating fluidized bed boiler with electrostatic precipitator and wet FGD facilities. The efficiency of dedusting in these two boiler rooms could not satisfy environmental protection indicators of Urumqi. Retrofitting of these boilers is detailed in Table 8.1-2. By the end of 2010, retrofitting of dust precipitator and FGD equipment for all boilers in the two peak load boiler houses has finished.

In China, flue gas on-line monitoring connected to local EPB is installed at the

stack which is usually just one for a CHP or a boiler house. Therefore, monitoring result shows the emission level of the final discharge from the entire plant. Online monitoring data in heating season (November and December, 2010) of related heat sources was collected, see Table 8.1-4, which show Lanzhu and Shiyue boiler house and Hongyanchi CHP can meet all relevant air pollutant emissions standards.

boiler rooms all met the Grade III standards (criteria for discharging into municipal sewage system) in the national “Integrated Wastewater Discharge Standard” (GB8978-1996) of China. 8.1.4 Solid wastes

Main solid wastes of the CHP plant and the peak balancing boiler rooms are slag, fly ash and wastes generated from desulfurization. According to relevant regulations and standards in China, fly ash from coal-fired thermal power plant and boilers are not classified as hazardous wastes, but industrial wastes that can be recycled, e.g. in producing lower grade building material. The solid wastes from SHN heat sources are mainly utilized to produce construction material. The rest is transported to and disposed of together with domestic wastes in municipal landfill. The solid waste volume is listed in Table 8.1-6.

In conclusion, the environmental performance of these heat sources in terms of air emission, water pollution and solid waste management meets relevant environmental requirements in China and of the WB.

8.2 Project activity undertaken in 2010

According to the implementation schedule of the project and Urumqi government’s requirement to speed up the expansion of district heating, part of the project construction activity financed by the counter-part funding had started since April 2010 for both components. The construction has to stop around October 2010 when winter came and can only resume April next year normally.

In order for these activities undertaken during 2010 before the project appraisal to be eligible as part of the project under counter-part funding, a due diligence review is required by the Bank to see if it meets the Bank’s requirements on safeguard. The EA team reviewed both the existing EA documents (domestic EAs prepared by another EA institute and already approved by Urumqi EPB) and their implementation on the ground during 2010 construction season. Findings from the review are presented in the environmental due diligence report of 2010 activities.

The domestic EAs for the entire project were approved by Urumqi EPB before bidding of the construction. Based on domestic EAs, draft EMP was prepared by the EA team according to the Bank’s safeguard requirements early 2010. The draft EMP, mitigation measures from the domestic EAs supported by local engineering code for construction management were distributed together with design documents to the construction companies and the supervisors. Environmental training was also provided to the construction companies and the supervisors by the EA team. The noise and dust were monitored during the construction phase.

The conclusion of the due diligence review is that project activities undertaken in 2010 have met the Bank’s requirements on environmental safeguard. Good practices from the 2010 construction program will be incorporated in the final EMP and continued during project implementation, such as distribution to affected residents a bilingual information booklet (in Chinese and Uyghur, see Annexes for originals) about construction activities, schedule, and alternative routes.

The review also identified some gaps in 2010 activities and made the following major suggestions for improvement to be incorporated in the final EMP and its implementation:

• In light of the features of different construction stages, it is suggested to conduct the supervision at three stages, viz. trench excavation stage, pipeline welding and laying stage and earthwork backfill stage.

• Mitigation measures shall be adjusted in light of different sites. Some measures shall be strengthened according to the features of sites.

• Communication with affected groups could be carried out in various ways to minimize the impacts of this project.

• Horizontal and vertical coordination is needed to ensure that the construction is in order. In this way, adequate information could be obtained.

9. CONCLUSIONS The centralized heating by CHP in the UDHP proposed to replace scattered

heating is in accordance with national industrial and energy polices, the “Urban Heating Plan of Urumqi (2006-2020)” and principles in the “Urban Master Plan of Urumqi”. The pollution control measures are practical and effective. The emissions of all the pollution sources can meet the standards. The emission inventories can satisfy the total amount control indicators promulgated by the UMEPB. After the implementation of the SHN, 117,440 ton standard coal would be saved per year. 9,157 ton SO2, 3,574 ton dust and 325,600 ton CO2 emissions would be reduced per year.

The UHN component mainly includes pipeline network, pressures-isolated heat

exchange station and substation works. The adverse impacts of this project on the environmental are limited.

The key environmental impacts during the construction phase include

construction noise, dust, wastewater and solid waste and domestic wastes caused by the construction of the pressure-isolated heat exchange station and substations, as well as the construction noise and dust and impacts on traffic during the construction of pipeline network. Mitigation measures include properly arranging construction time and technology to control noise, watering to reduce dust and disposing domestic and construction waste in designated sites (see the detailed measures in the EMP).

The key environmental impacts during the operation phase include construction

noise of the pressure-isolated heat exchange station and substations. The mitigation measures include the ones to reduce noise of high-noise equipment to ensure that the noise can meet national and local standards.

After the project is implemented, the construction of new small boilers could be

effectively controlled, the pollutant emissions from which could be reduced. To conclude, in the context that all of the environmental equipment is operated well, this project is environmentally feasible.

ANNEXES

Annex 1

Traffic Management Plan during Implementation of the Project The Plan includes two parts. (1) Relevant preparation before work commencement and (2)

Daily management plan during construction. The Plan is prepared according to Road Traffic

Safety Law of PRC, Safety Production Law of PRC, Technical Specifications for Road

Engineering Construction Safety, etc. Every unit and individual works for the Project and

residents and pedestrian should follow the traffic Management Plan.

1�Plan for Relevant Preparation before Construction 1.1 Working Ideas that Person in Charge should have before Construction

1.1.1 The purpose is safety and providing convenience for people, coordinating all parties to

have good information and minimizing adverse impact of traffic safety to people.

1.1.2 According to the principles of “Safety is first and prevention is basis” and “Safety

should be taken care during production”, safety production should be conducted. Production and

safety should be planned, arranged, checked, summarized and evaluated at the same time.

1.1.3 Person in charge of construction teams will be responsible for construction safety.

1.2 Preparation for approval before construction

1.2.1 Construction teams should provide written application to relevant traffic police and

road policy team for approval before carry out construction. Wrriten application documents

include approved documents by Urumqi Planning Bureau, design drawings about road

traffic(provided by qualified design institute) with seal of Urumqi Traffic Police Team,

construction organization plan (attached with safety facility arrangement map), contract, copy of

supervision work contract, warranty agreement, work checking and acceptance table (attached

with comments of traffic police agency).

1�2.2 Construction teams should actively consult traffic volume and traffic safety from

traffic police, road policy team, affected community, relevant agencies, etc. and prepare traffic

control and safety guarantee measure on the basis of design and technical requirements and

improve construction safety plan.

1.2.3 Before approve by department in charge, approval should be obtained from traffic

administrative department of public security.

1.2.4 Work that occupies one lane with length not more than 50m and can be completed

within one day should be submitted to traffic poly and road policy team for approval 10 days

before construction. Works that occupies carriageways (including emergency lane) and

construction period does not exceed 30 days should be submitted to traffic poly and road policy

team for approval 15 days before construction. For the road needs to be full closed (including

emergency lane) and construction period is over 30 days, application should be made 20 days

earlier and traffic police and road policy team will have site visit to check safety organization plan.

1.2.5 Prepare Emergency Aid Plan during Construction for the Project according to

characteristics of the Project for approval and filing.

1.3 Site visit


��

1.3.1 Using non-motor ways as much as possible (sidewalk, for example) and landscaping

area could be temporarily occupied to avoid affecting traffic. For example, during construction at

North Nanhu Road, measures were used were removing medium strip and lamp post temporarily

and then leveling and paving road surface, dividing the main road by fence and leaving 5 lanes at

west side and occupying 2 lanes at east side for construction. Such measures could mitigate traffic

block efficiently.

1.3.2 Temporarily increase and adjust routes and stops of public bus, distance passenger bus

and tour bus. It should comply with travel requirements of traffic planning, smoothness, and

convenient.

1.3.3 Go to site to learn traffic block time and establish relevant traffic diversity and bypass

solution. For example, North Kunming Road (Suzhou Road-Kexue Yijie section ) and Kexue

Yijie�North Kunmin Road – Tianjing Road section�were full closed for construction, and only emergency vehicles and construction vehicles were allowed to pass. Therefore, plan should

consider to diverse traffic to other roads and built temporary bus stops.

1.3.4 Construction can only be carried out during night at busy sections such as railway

station section. During construction, traffic police should patrol every day to guide traffic. Some

workers can be arranged during day to assist traffic police to guide traffic. Access for traffic

should be planned earlier.

1.3.5 Coordination should be made if there is cross with other project. Eg. There was

crossing construction between water pipeline and heating supply project at Nanhu Road and

which requires very high professional technique. Construction sequence should be well arranged

before construction and professional person should work for restoration to minimize affect to

traffic.

1.3.6 If alignment is difficult for construction, new construction plan should be prepared

soon to avoid construction delay and affecting timely restoration of traffic.

1.3.7 Temporary access should be remained at dense population and business areas to

minimize affect to business.

1.3.8 Construction team should investigate sinking works along alignment to avoid damage

to optical cable, electric cable, road facilities, sewage pipeline, etc.

1.4 Disclosure of implementation plan.

1.4.1 For full closed construction sections, Urumqi Traffic Police Team and Road Policy

Team should disclose to public with both Chinese and Uygur language.

1.4.2 If public bus that route should be adjusted, advertisement should be made 10 days

before to public.

1.4.3 10 days before construction, relevant affected administrative department should be

informed about the details of construction so that they can communicate with businessmen to do

relevant preparation.

1.4.4 10 days before construction, communication should be made with directly affected

schools and tell them the relevant safety measures to be adopted so that school can do some

preparation and carry out safety education to students.

1.4.5 Propaganda should be well done though various media. Construction should be

transparent to let citizens to know the details of construction plan and the affect in advance

through various media in both Chinese and Uygur language. A 24-hour hot line should be set with

duty and record all information and report and feedback. Construction information should be


��

�

disclosed to public through media and bulletin board at construction site. Comments of public

should be reported to relevant authority in time.

1.4.6 Popularize the importance of “Blue Sky” project through various media and main

methods and basic implementation process to let public have knowledge about the Project. Special

attention should be paid to issues that may cause adverse impact and explanation should be made

in advance so that public can do some preparation in advance.

1.4.7 Before construction, information board should be set at beginning and ending places of

site and information as planned construction period, road section, persons in charge (and his/her

telephone number), emergency telephone number and hot line should be disclosed.

1.4.8 Before construction, various propaganda means can be used to hire some volunteers to

assist traffic police. Uniform and tools can be provided to them by Heating Energy Company to

help in guiding traffic nearby school, communication, hospital, or where there is more

population.

1.5 Preparation of different travel plans for different situation

1.5.1 Present policy can be adopted at busy sections ( odd and dual plate numbers) and timing

available for traffic,etc.

1.5.2 When construction involves large community, temporary access or bridges should be

available and effective communication should be made with community so that residents could

have some ideas.

1.5.3 When there are special organs in the project area, such military area, temporary access

should be reserved for petrol according to military security requirements.

1.6 Safety training before construction

1.6.1 Safety organization established at site before construction should have 1%~3% of total

staffs working at site (who are familiar with local situation and language have priority). They will

be responsible for the safety of workers and safety works and preventing accident from happening.

Safety staffs have right to issue orders according to relevant regulations and adopt protection

measures to prevent accident from happening.

1.6.2 Before construction, safety education should be carried out to all workers at least once a

day they should sign their names for checking.

1.6.3 Explosive and flammable materials should be well stored and sufficient fire-fighting

equipments should be equipped. All workers should be familiar with the property and using

methods of the equipments.

1.6.4 Before construction, education on policy on ethnic minorities, knowledge of their

costumes, etc. should be conducted to avoid problems.

1.7 Establishment of construction files.

1.7.1 Establishment of using file for various signs, publicity board, baffle, etc.

2 1 Different Safety Measures for different Conditions

2.1.1 For Full closed road section, warning signs and lamps should be checked all the time

during construction. Starting and ending points should be fully closed to avoid people coming

into the site. Safety patrol should check during break tine to ensure safety.

2.1.2 For half closed road section, width of road should be ensured for traffic safety. Warning

signs should be set 50m ahead of construction site and mention the ways to go. Nigh warning

signs should be luminous with both Chinese and Uygur languages and lightening.

21.3 For the road sections allow for traffic both directions, safety shield should not be

removed for the purpose of construction and traffic safety should be ensured. Construction site

should be cleaned in time to avoid adverse impact by waste materials.

2.2 Special conditions for sensitive areas

2.2.1 For Mosques and accesses where there are more pedestrians, relief road should be set

and safety work should be done well. For example, access connecting South Youhao Road and

Xibei Road is the main road for religious people living nearby to go to Xidaqiao Mosque. It is

suggested to have half lane closed construction and set fence in the middle and no auto is allowed

to ensure safety of pedestrians. Do not on look religious activities during construction.

2.2.2 For schools, construction is better to be implemented during summer vacation. If time

is not available, protection fence should be set and remain pedestrian crossing nearby. Warning

signs should be set and safety management during on and off school time should be strengthened.

Meanwhile, contact with local community to assist management. Road should be restored

immediately after construction completion.

2.2.3 For hospitals, they have many emergency bus (Called 120) and it is specified that they

should park within 500m for emergency call anytime. Therefore, special place should be

remained for hospitals for parking. Temporary access for hospital should be wide enough to

facilitate hospitals’ need.

2.2.4 For military area, it is not allowed to stay in such sensitive area. Any suspicious

situation should be reported to duty of military area in time and construction period should be as

short as possible.

2.2.5 For passenger terminals, construction period is better to be arranged between April and

July so as to avoid holidays and complete before the end of summer vacation. It I better to conduct

full closed construction to accelerate construction speed. For example at Southern Xinjiang

Passenger Terminal, due to busy traffic and frequent traffic block, it is better for full closed

construction and guide traffic to go the other ways. During construction, traffic lights at Water

Park should be stopped. It is because there was heavy traffic during 2009 construction because

traffic lights were not stopped.

2.2.6 Besides reserved accesses, lightening and warning signs during night should be

available and have patrols.

2.3 Implementation rules during construction

2.3.1 Periodical safety coordination meeting should be held to inform relevant laws and

regulations on safety construction.

2.3.2 Warning signs should be set at least 50m ahead of coming vehicles and signs should be

in both Chinese and Uygur languages. During night, it should be no less than 100m with

2.3.15 All construction equipments should be checked periodically and safety inspector

should record and sign. It is not allowed to use any unqualified equipments, facilities, etc. 2.3.16 All construction vehicles and equipments should be painted with unified color.

Construction signs should be hang behind vehicles. Yellow waning lights should be on during driving and operation. All vehicles should go in and out of construction site from specified entrance and exit and not allowed to park outside of construction site. After completion of work, it is necessary to withdraw from construction site in time to avoid adverse impact to traffic. It is not allowed to use illegal vehicles for construction.

2.3.17 Construction period should be well arranged to avoid occupying road or work during

night. In case road should be occupied, lashing light and guiding lights should be set at

construction site.

2.3.18 During construction, necessary speed limit and warning is required during

construction. Various electronically devices should be used to disclose construction information in

time to warn drivers passing by.

2.3.19 During construction, it is better to excavate left side of main road and then right side.

Minimization of cross-section is proposed.

2.3.20 Workers should set and remove safety signs and protection facilities in order.

3�Works after completion of construction 3.4.1 After completion of construction, construction teams should remove barriers on the

road and backfill the site immediately. Construction site should be well leveled to restore to

original one. Hidden safety troubles should be eliminated and traffic should not be opened before

checking and acceptance by traffic police and road policy team.

3.4.2 After construction, redesigned drain well should be at one level and in one line. It

should be considered because it may affect traffic.

4�Measures for temporary situation 4.1 Construction can be conducted as approved date. If completed in advance, approval

agency should be informed. If extension is necessary, application should be made by levels and go

through all procedures.

4.2 Emergency rescue due to damage of bridges, road, facilities or traffic accidents can be

priority under the condition of safety. But report should be made to traffic police and road policy

team within 12 hours. 4.3 In case of Grade I security duty, construction teams should stop the work according to

requirements. 4.4 Work should be stopped in case of bad weather. During temporary stoppage, warning

signs, guiding lights should be increased and other effective temporary remedy measures should be adopted to reduce adverse impact caused by construction to traffic safety.

4.5 In case of injury, call 120 immediately for first aid and report to head quarter soon. 4.6 In case cables are damaged, report should be made to headquarter immediately and
