1.1 Project Background
1.1.1 Relevant policies of Liaoning Province
Liaoning Provincial Government has been supportive of the application for the World Bank loan which will be used for funding the sub-projects. A coordination group for the implementation of LMC3 to use the World Bank loan has been organized by the General Office of Liaoning Provincial People’s Government, which is primarily in charge of examining and determining the master plan, organizing and coordinating the implementation of initiatives to address key problems encountered in the development of policies, and institutions. The group consists of representatives from Liaoning Provincial Government, Financial Department of Liaoning Province, Liaoning Provincial Environmental Protection Bureau, Construction Department of Liaoning Province, Liaoning Provincial Price Bureau, Development and Reform Commission of Liaoning Province, Price Control Administration of Liaoning Province, Department of Audit of Liaoning Province, the Land and Resources Department of Liaoning Province. The Office of Utilizing the Foreign Capital and Urban Construction is in charge of the daily management under the leadership of the coordination group. Table 1-2 Issues concerning heat and gas supply in the various midland cities Citie Projects Name of Project District or local heating situation s Anshan Central Heating Project in the North of 1 A Large number of scattered small boiler rooms with small (Hai Yong’an Road Tiedong District Haicheng capacity, low heating efficiency, serious energy loss and cheng) City environmental pollution, excessive working loads for operators. Heating network Construction of Heating 2 Most of the boiler are running under overload without Fushun Unit Expansion for Fushun Electric meeting heating supply requirements. The number of houses Generation Plant with an indoor temperature ranging from 10 to 14 within the Central Heating Project in Nanfen District service area accounts for 30% of the total. Benxi City 3 Too simple smoke and dust removal equipment, absent of Central Heating Project for Benxi Iron & desulphurization devices, severe environmental pollution; piping Benxi Current Steal Thermal Development Company network out of repair, water loss rate up to 4% 8%; the situation Phase Central Heating Project of Benxi pipelines are elevated over the urban districts in some cities, of heat City which cause passive impact on the landscape.. supply Liao Central Heating Project in Gongchangling 4 the service areas are not reasonably planned, leading to yang District Liaoyang City overlapping of the service area to be serviced by different plants. Central Heating Project in Dashiqiao District Yingkou City Numerous of small heating enterprises with poor Ying Central Heating Network Project in Yingkou management and service. kou Economic Development Zone Huaneng Central Heating Project in North Part of Yingkou Hulu Central Heating Project in Yangjiazhangzi dao Mining Area 1 Natural gas pipelines are not well repaired and maintained for the past 30 years. Particularly after the impressed current cathodic protection system for the pipeline were removed in 1990’, the degradation of the pipelines has be enhanced, which leads to a serious leakage of the gas. In some are, the pipeline can merely transmit the gas under low pressure, which consequently neither meet the requirement of gas transfusion nor reduce the operational cost. 2 There are two wet gas storage tank with the capacity of 20,000 m3 and 50,000 m3 respectively, which were put in use in 1989 and 1995 without any overhaul in the gas source plant. 3 The medium pressure pipeline in Yingkou city has been Current operating for over 10 years, and the mechanical flexible joints situation Ying Rehabilitation and Expansion Project for Gas on some sections have get loose with slight leakage. The of gas kou Facilities of Yingkou City consequence would be disastrous if the gas spreads to the supply building or the sewers. In addition, with the constant expansion of urban area, occupation of the buried pipeline by other structures and buried depth changes can be found everywhere. The valve well on the pipeline, and most of the condense cylinders are damaged to various degree. 4 Besides, Yingkou city is located in Liaohe estuary with low-lying terrain, high acidity and alkalinity and serious chemical and electro-chemical corrosion in some parts. With too limited corrosion proof method, and shortage of electro- chemical countermeasures, auxiliary facilities such as the condense cylinders are being damaged at a rather fast speed, resulting in the increased management cost and safety risks.
1.1.2 Heating and Gas Supply Situation and Problems in Central Cities of Liaoning Province
Cities applying for the loan from the World Bank are Anshan, Fushun, Benxi, Liaoyang, Yingkou and Huludao. At present, problems such as plenty of small boiler houses, poor heating quality and serious environmental pollution, aged gas supply systems without repair exist in all cities. Please refer to the environmental management plans of all sub-projects for details.
1.1.3 EA Category
According to the World Bank’s safeguard policy, Environmental Assessment OP4.01, this project has been classified into Category B, as it has short construction period, mature and reliable technique, controllable pollutants discharge and the confined scale of environmental impact.

3.4 Incidence of Respiratory System Diseases
China is one of the countries that rely on coal as primary energy source, leading to quite serious coal smoke pollution. At present, every city in Liaoning Province suffers from terrible air pollution due to extensive burning of coals. Statistics have shown an increase of respiratory system disease during winter and spring in all the cities, which are resulted from increase of inhaled particles and sulfur dioxide caused by burning of coals in boilers during heating periods.
Inhalation of SO2 will damage the function of respiratory system and aggravate existing respiratory system illness. PM10 also can contaminate lungs of human after being inhaled. Based on the information provided by local hospital which located at Haicheng, Benxi, Dashiqiao, Nanfen, Gongchangling and Yangjiazhangzi, the incidence of respiratory system disease is greater than that in summer. 3.5 Acoustic Environmental Quality and Sensitive Receptors

Environmental Impact Analysis 4.1 Analysis of Positive environmental impact
4.1.1 Ambient air quality improvement
After central heating become available, a large number of small boiler rooms will be closed and no longer be used, so the district air quality of the project cities will be improved to some extent. The numbers of small boiler rooms to be closed are listed in Table 4-1.

As there are no regular monitoring stations established at the three areas such as, Gongchangling, Nanfen and Yangjiazhangzi, it will be unable to collect the routine monitoring data of the air quality within the previous three consecutive years, thus it is very difficult to establish and run the reverse model. We can only adopt the conventional model recommended in the Technical Guideline for EIA issued by SEPA to predict the impact on the local air quality as a result of the demolition of the small boiler rooms
The following is the model used for prediction: zReverse Model " Reverse model" is employed to assess the air quality changes generated by retired boilers; the formula is as follows:
PS=Pbackground + P0 ES/E0
The improvement degree % = P0- PS / P0 ×100 Of which: PS —the concentration of particular air pollutant in the area where small boilers have been demolished, mg/m3; Pbackground — the background concentration the particular air pollutant emitted from other pollution sources within the same area, mg/m3; P0— current concentration of the particular air pollutant within the same area, mg/m3; ES—the emission rate after the boilers have been closed down, kg / h; E0—the present emission rate of the particular air pollutant, kg / h, zGaussian Model The normal mode recommended in “Technical Guidelines for Environmental Impact Assessment " (HJ / T2.2-93) is to be used to predict the air pollutants concentration emitted from a point source along the ground-surface axis. -- The dispersion model of point source in windy days -- Assuming the chimney location on ground as the origin, the concentration of the Q Y 2 +4 ()2 − Henh 2 ()2 + Henh 2 c = exp− ∑ exp. − exp−+ σσπ σ 2 σ 2 σ 2 2 U zy 2 y n −= 4 2 z 2 z pollutant on the ground point in leeward with the coordinate being (X, Y) will be determined by the following formula: zIn the Formula: Q – Emission volume per unit time, mg / s; Y -- The vertical distance in horizontal direction between the prediction point and the average wind direction axis through the exhaust funnel, m; x – The level horizontal diffusion parameter that is perpendicular to the average wind direction, m; y -- Vertical diffusion parameters, m; U -- The average wind speed at the exit of exhaust funnel, m / s. The ground wind shall be assumed as the representative wind speed at various stabilities; H -- Mixed layer thickness, m; He -- Effective height of exhaust funnel, m. zThe diffusion pattern of the point source when slight wind and static wind Assuming the ground position of the exhaust pipe as the location of the origin, the direction of the prevailing wind is along X axis, the concentration CL of any point on ground (X, Y) with the sampling time less than 24 hours shall be calculated by the formula: = 2Q L YXC ),( 3 .G ()2 ηγπ 2 2 02

Other projects are just the heating pipeline network construction. Among these six projects, such as Nanfen, Gongchangling and Yangjiazhangzi have no routine monitoring stations. Therefore, the reverse model is only used to predict the impact on environmental air quality for the boiler room demolition program in the central heating project on the north of Yong’an Road, Tiedong, Haicheng city, Haicheng city and the centralized heating project of Dashiqiao district in Yingkou and Phase Central Heating Project of Benxi City .these results are shown in table 4-2: Table 4-2 Summary of Predicted Air Quality Improvement 3 Projects Pollutants PS mg/m The improvement degree on the atmospheric environmental quality

4.1.1.3 Impact of other projects on atmospheric environmental quality The routine atmospheric monitoring data for three years is not available in such three regions as Nanfen, Gongchangling and Yangjiazhangzi, therefore it is very difficult to use the reverse model. The Gaussian plume model is used, with the source intensity of the boilers to be demolished being inputted into the model as a negative value, and the intensity of the source of the proposed boilers being to be inputted as a positive value, to predict the impact on the local air quality. After the project, as some small boiler rooms are demolished, pollutants concentrations will decrease in the sub-project areas, the predicted decrease of the pollutants concentration is shown in Fig. 4-13~, Fig. 4-18 and table 4-5.

4.1.3 The health condition improvement
At present, due to the coal combustion, various cities in Liaoning province have serious air pollution problems. A survey of respiratory disease records in hospitals indicates that there is an obvious increase in respiratory diseases in winter and spring all over the cities in recent years that is considered primarily due to the increase of particulate matters and sulfur dioxide emitted to the air during the heating period.
Centralized heating project is intended for conserving energy and improving the environment, and also greatly reducing the fine particulates and sulfur dioxide that discharged into the air. Therefore, after the project, as a large number of small boiler rooms are closed, the project area will have an improvement in the local air quality, hence reducing the local residents’ respiratory disease incidence . 4.2 The analysis of adverse environmental impact during construction The adverse environmental impact during the construction phase of the project mainly include the followings: the impact of air-borne dust upon the ambient air quality, the impact generated from the construction machinery, the exhaust gas of transportation vehicles; the impact on ambient environment resulted from the domestic sewage generated by a small number of construction staffs; the impact resulted from the construction noise and construction spoils. 4.2.1 The safety concerns of contractors
A number of contractors will be engaged by the project. Due to the scattered construction site, the relatively poor living and sanitary conditions, the intense laboring and diseases will be easy to spread. In order to ensure the safety of construction, it is necessary to conduct a comprehensive physical examination on the operation staff, and strictly prevent the personnel suffering from contagious diseases from entering the construction site, the medical staff shall also conduct periodic medical examinations, if the disease is found, treatment shall be done in timely manner and the patient shall be transferred out to hospitals, so that epidemics can be prevented from further spreading. As the construction sites are located in urban areas, tap water can be provided in the workers, camps. In addition, the construction site should be provided with medical and health facilities and medical personnel. So the safety and health of the workers can be safeguarded.. 4.2.2 Analysis of the pollution generated by the heat source plant and heat exchange stations
(1) The impact of air-borne dust during construction The air-borne dust during construction phase is mainly caused by the operation of transportation vehicles and construction machines, according to analogical survey data, it can be seen that the impact of the dust resulting from the construction and transport vehicles will impose greater impact upon the area within 30m from the road, and the roadside TSP concentration will be above 10mg/m3.
(2) Waste gas during construction The pollutants from oil-burning machinery and vehicle exhaust pipes mainly include NO2, CO and CmHn, the test results indicate that the concentration of NO2 can be up to 150 g/m3, which my affect an area within 200m from the road.
(3) Waste water during construction The waste water during construction phase is mainly from cement mixing and equipment maintenance in the construction process, and the domestic waste water from workers’ camps. The main pollutants are SS, CODCr. Although the volume of waste water is not too much, it will have an impact on the local water environment in construction area.
(4) Noise during construction Noise during construction is mainly generated from the operation of various machinery and vehicles and bulldozers, excavators, loader, and concrete mixers, etc.
During earth and stone work phase, once at 40m away from the construction site , the noise level exceeds the standard value of 75 dB (A) at daytime, and at 200 m from the site the noise level exceeds 55 dB (A) at nighttime; during the foundation preparation stage, once at 60m from the site the noise level exceeds the standard of 85 dB (A) at daytime, the construction should be prohibited; during the structure construction phase, once at 40m from the site the noise level exceeds 70 dB (A) in daytime, and 200m from the site in night exceeds 55 dB (A), the construction should be prohibited. By contrast and comparison, the noise level in this project will below the respective standard limit. In addition, the transportation vehicles will be a noise source. Under normal circumstances, the transportation vehicles will generate less noise impact at daytime; while in night the transportation vehicle noise would cause important impact on residents. Therefore, the transportation time of vehicles should be carefully scheduled so as to reduce the impact upon the surrounding environment.
(5) Spoil disposal and backfilling in construction project During the project construction phase, the site will be leveled. During the construction phase, spoils will be produced from soil excavation and structure demolition. If the spoils are not disposed of in a proper manner, they will affect the environment in the construction site. Particularly in strong windy and dry days, air-borne dust will occur and impose adverse impact upon the surrounding environment. 4.2.3 Analysis of the pollution generated by heating pipeline network
The impact upon environment generated in the process of heating pipeline network installation and construction. Impacts may vary with different installation methods.
(1) The analysis of atmospheric environment impact The flying dust in construction phase is the major reason causing air pollution in the process of pipeline network construction The air-borne dust is mainly produced in the course of earthwork excavation , stockpiling, materials transporting, structures demolition, backfilling; the exhaust gas emissions from construction machinery, the main pollutants are CO, NO2. When the wind speed is higher than 3.5 m/s, and relative humidity is less than 60%, the strength and scope of the air-borne dust impact is shown in Table 4-8.
Table 4-8 Strength and scope of flying dust impact during construction Distance from the 10 20 30 50 100 construction site (m) Flying dust concentration 10.14 2.89 1.15 0.86 0.61 mg/m3
The flying dust in construction site is generated mainly by the transportation vehicles, which accounts for about 60% of the total and is closely related to the road surface condition and the speed of the vehicle. Under normal circumstances, the flying dust produced at the construction site and the construction roads under the natural wind will affect an area in a radius of 100m from the site.
During the construction phase, sprinkling water on the traffic road surface will significantly reduce flying dust; the dust will be reduced by 80%. The impact of flying dust after sprinkling water in the construction site is shown table 4-9.
Table 4-9 Flying Dust Impact after water spray Distance from the construction site (m) 10 20 30 50 100 The concentration of flying dust after spray 2.01 1.40 0.67 0.27 0.21 water on the road surface(mg/m3)
Table 4-9 shows that sprinkling water upon the construction site and the transportation road can effectively reduce flying dust; the dust concentration at the area 50m from the construction site is 0.27mg/m3, which can meet the environmental standards.
As the pipeline construction period is short and the implementation of such mitigation measures in the process of construction, flying dust during construction will has limited impact upon the surrounding residents. With the end of the construction period, the impact will disappear.
(2) Analysis of the water environmental impact The domestic waste water discharged by the constructors in the construction site of the pipeline network installation is the major water pollution source during construction phase. For different stages of the construction period, the number of constructors will vary; the number generally is about dozens of people but varies from one stage to another. Based on the daily water consumption rate at 50L/ person, and 80% of the water consumed is to be converted to wastewater, the average sewage discharged by per person per day will be 40L/ person. by analogy, the loading of SS is 180mg/ L, CODcr 240 mg/ L, ammonia 25 mg/L. If the above mentioned domestic waste water is discharged directly into waters, the receiving water environment will be degraded; Therefore, sanitary facilities should be provided at sites, and the oil- separating sedimentation basin facilities for sewage treatment should be installed; Due to the short construction period, the wastewater discharge will not have important impact on the environment after the mitigation measures are in place.
(3) The analysis on the solid waste impact The impact mainly comes from the domestic waste generated by the constructors, the construction waste left by construction process, such as packaging bag, building spoils, etc. The domestic waste shall be collected and sent to the landfill for disposal.
The spoils will be collected and stockpiled on a designated site and transported by local sanitation department to a deposit for landfill. All solid waste will be reused on site by careful balance of earth work to the best extent, and thus they will impose small impact upon the environment.
(4) Analysis of the acoustic environmental impact The machinery, mainly including mechanical loaders, road rollers and loading trucks, can produce relatively intense noise during the construction. Major construction equipment noise level is given in table 4-10.
Table 4-10 Noise of Major Construction Mechanical Equipment Construction machine mechanical loaders road rollers loading trucks Noise dB(A) 80 75 78
Construction noise will impose rather greater impact upon the neighborhood community or school close to the proposed heat exchange stations, and the first row of roadside residential buildings along the pipeline.
As the construction period is short, and the operation of construction machinery is temporary, after the construction is completed, the impact on the acoustic environment will disappear. therefore, in the project construction period it has acceptable impact upon the acoustic environment.
(5) Analysis of the traffic impact The impact on traffic during the construction phase is to take place on the pipeline construction sections, which covers three aspects: zbreaking road during the pipeline construction will block the traffic; zthe heaping up of the earthwork and the road excavation will block the traffic; zthe increase of transportation vehicles on the road will increase the vehicle flow.
Pipeline construction has relatively great impact upon road traffic. Although the pipeline will be constructed in several sections, the excavated soils still needs to be stockpiled temporarily, which will cause some impact upon the road traffic along the pipelines. Where the pipelines need to cross a road, the section of the road needs to be closed which will cause significant impact on the traffic on this road. If the pipelines are constructed along the sidewalk, the impact on the pedestrians may be important.
For this project, the amount of materials to be transported is not very great,. In addition, the demand for materials is not concentrated on a particular site. Therefore the impact caused by the increased vehicle flow for this project will not have important impact on the local traffic..
(6) Analysis of the ecological environmental impact The pipeline construction process will have certain degree damage upon the vegetation on both sides of the road, and at the end of construction, we shall restore the vegetation as soon as possible.
(7) Analysis of the pipeline risk Pipeline construction will be conducted on the both sides of the roads. There is municipal pipeline network on both sides of the main road (rain water pipeline network) and the gas pipeline. The main risk to be encountered during construction phase may be the inappropriate construction which results in the damage to the municipal pipeline network, resulting in leakage of rainwater and gas. The ;leaked gas will cause explosions, fires and other accidents.
(8) Among the 11 sub-projects , there are three sub-projects, Central Heating Project in the North of Yong’an Road Tiedong District Haicheng City, Central Heating Project in Yangjiazhangzi Mining Area and Central Heating Project for Benxi Iron & Steal Thermal Development Company, that need to remove asbestos during construction phase. The fiber of asbestos will be released to the air and suspended for a long time. If the asbestos fiber inhaled by the workers, they will accumulate in the lung and lead to pulmonary diseases.
4.3 Analysis of Adverse Impact upon the Environment During the Operation
4.3.1 Ambient air quality
The air pollutants to be emitted from heating plants which burn coals, may mainly include TSP and SO2.

2 The height of stack is designed by the design institute. The air quality forecasting results indicate that the impact of these new boilers on air quality can meet the applicable standards. Thus the height of stack is reasonable.
3 XP dry-wet two-stage combined desulphurization and dedust technology is employed in this project. This technology is an innovation and improvement of conventional lime desulphurization technology by wet method. it was put into use and innovated in industry since 1994. This process involves exhausting flue gas out of a boiler economizer system, then removing dust by means of a dust catcher ( bag dust catcher with a dust removal efficiency over 99.7 ), then introducing the flue gas into a wet thionizer ( desulphurization efficiency over 90 ) by a induced draught fan, and then further removing the fine dust particulates, as well as moisture and fog in the flue gas, finally exhausting to the air through chimneys. Calcium sulfite produced in the process of desulphurization will be oxidized to calcium sulphate at the bottom of thionizer.
The two-stage desulphurization and dedusting process is employed in the process, which involve dust removal by dry method followed by desulphurization, but without settling tank. Corrosion-resistant XP tray device for effective dedusting and desulphurization as well as demister are used. These devices are adaptable to greater variation of loading so as to ensure steady operation of the devices as their structures is rational and the operating range is wide. The deducting rate and desulphurization rate of XP-type desulphurization with a single tray are higher than that with a rotating stream tray, by 5 10 and around 20 respectively.

To mitigate the impact on acoustic quality, various measures are to be adopted as shown in table 4-13 below:
Table 4-13 Summaries of noise control measures Noise source Control measures Boilers Set up shock proofing cushion Establishing muffler and sound insulation cover, and employ hose to connect the Blower and induced fan pipeline air vent Setting up muffler pumps Installing sound insulation cover, and sealing off the pump rooms vehicle operation operate inline with schedule, route, and decrease the whistles Shock absorption, soft hose connection, and install sound insulation devices at the Heat exchange station heat exchange station near to the residential area
Above-mentioned pollution control measures are developed to take such three aspects into consideration as noise source, transmission means and sound-receiving body, so as to ensure that the noise level in plant boundary and neighborhood can meet the standards.
The modes employed by these sub-projects to forecast the impact upon noise environment are as follows: Sound pressure level at the prediction point from an outdoor noise source
Loct®= Loct(r0)-20lg(r/r0)- Loct In the formula: Loct ®, Loct (r0) – the sound pressure level at the site r , r0 away from the sound source, dB; r, r0----the distance from the prediction point to the sound source, m; Loct ----various attenuation value, dB. If the octave band sound power level of the sound source Leve is known, and the sound source can be considered to be located on the ground. Then

The 11 sub-projects are different in the project content, and therefore, the contents on analysis of acoustic environmental impact also vary, which is as shown as follows:

From the above table, it can be seen that the acoustic environmental impact of the rehabilitation and expansion project of gas facilities in Yingkou City and Central Heating Project for Benxi Iron & Steal Thermal Development Company are different from that of other projects.
1 Analysis of equipment noise impact from heat source plant The major noise source of heat source plant is the boiler and various fans and pumps. After the project are put into operation, this operation equipment shall be installed indoor; the following is the prediction of the impact of the equipment in each sub- project upon the acoustic environment on the plant boundary and the surrounding neighborhood:

Table 4-15 shows that after the project, the noise level at plant boundary will increase to somewhat extent, but can still meet the requirement stipulated in the Standard of noise at boundary of industrial enterprises (GB12348-90) Grade II; the noise at the residential area surrounding the plant boundary can satisfy the Class 2 standards stipulated in Standard of environmental noise of urban area (GB-93).
NOTE The noise value at the residential area outside the south plant boundary of Yangjiazhangzi project exceeds the standard, because the value of background exceeded the standard. The noise of this project has no impact on it. (2) Analysis on the Noise Impact from Heat Exchange Stations
Operation of heat exchange stations will produce noise, which will affect the environmental sensitive receptors. Regarding the heat exchange station, the main equipment generating noise is the circulating pump and water replenishment pump. When the heating load in heat exchange station is greater than 3.5MW, three circulating pumps will be installed, with one standby; when heating load of heat exchange station is less than 3.5MW, two circulating pumps will be installed, with one standby; 2 water-replenishment pumps installed, with one standby.
Table 4-16 Analysis of Acoustic Environmental Impact from Heat Exchange Station
Name of project Analysis of acoustic environmental impacts
The results of noise level prediction using the mode recommended in standards of PR China environmental protection industry HJ/T2.4 1995 Technical Guidelines for Environmental Impact Assessment----Sound Environment indicate that , provided that the distance between residential area and heat exchange station is no less than 10m, the Newly-built heat exchange station impact of the operation noise of heat exchange station will be around 40dB (A) after the natural attenuation as the noise travel. Thus the noise level upon residents, and will not result in the noise in residential area exceeding the standard requirement. So, the EIA requires that in the process of heat exchange site selection, we should maintain the distance between heat exchange station and residential buildings to be over 10m, As for these heat exchange stations reconstructed on the basis of original heat exchange Upgrading of station or boiler room, if the distance between heat exchange station and the existing exchange neighborhood can not be maintained longer than 10 meters, the EIA requires that the station or boiler pump in heat exchange station shall install sound insulation cover, so as to ensure room acoustic environment of the residential area can meet the standard.
3) Analysis of acoustic environmental impact of the rehabilitation and expansion project of gas facilities in Yingkou City and the Central Heating Project for Benxi Iron & Steal Thermal Development Company
As the two projects do not involve construction of heat exchange stations and boiler rooms, the environmental impacts are different from others; the analysis on the impact on acoustic environment is as follows:
Table 4-17 Analysis of acoustic environmental impact Name of project Analysis of acoustic environmental impact After this project, the noise level on plant boundary will not be increased, so the current noise level on the plant boundary will be remain intact , which may satisfy the Class II standards requirement of the Noise Standards of Plant Boundary Industrial Enterprises The rehabilitation and (GB12348-90). expansion project of In addition, to mitigate the noise simultaneously released from the pipeline air release gas facilities in valve due to overpressure in the newly-built pressure regulation stations, the project Yingkou City design will increase the diameter of the overpressure pipe and install muffler on it. The newly-built pressure regulation stations are established at the intersection of main roads, after taking the measures, the fourth category standards requirement stipulated in Noise Standards of Urban Regional Environment (GB - 93) can be satisfied. The main noise source of this project include: first-level pump station and relay pumping station in power plants , the initiating pump station of coking heating network and sewage pumping stations and hot water pumping stations in sewage treatment plants.

After this project become operational, a large number of small boilers will be closed, the low and small stacks will be demolished. As a result, the urban air quality, and people’s living conditions will be improved, hence contributing to urban development. At present, all cities in Liaoning province are suffering from severe atmospheric pollution resulting from coal burning. According to the survey, a significant increase of respiratory diseases can be found in all cities in winter and spring, for which the primary reason is coal burning boilers that produce more particles can be inhaled and sulfur dioxide during heating period. Centralized heating project is the basic solution for saving energy, improving environment and decreasing the emission of particles can be inhaled and sulfur dioxide. Therefore, when this project is put into use, with closing down of small boilers, ambient air quality in all regions can be improved and the rate of respiratory diseases can be reduced significantly.
