3Project Overview

3.1 PROJECT BACKGROUND

Currently, within the urban area of Yixian, only 1 building of Jinzhou Guanda

Heating Power Co., Ltd. in the south provides the central heating heat source, 4 placess of

scattered small boiler rooms, and a total of nine hot water boilers with a total capacity of

250.5MW, total heating area of 2,445,300 m2, of which the central heating area is of

2,105,300 m2.The central heating souce Jinzhou Guanda Heating Power Co., Ltd. is

located in Houyang Village, Chengguan Township, Yixian County, which covers an area

of 35,000 m2, currently it has 43 regional heat exchange stations (including a heat

exchanger station within heating source plant), and the heating capacity is 215MW, with

two sets of 70MW (2 × 100t / h), 1 set of 46MW (65t / h), 1 set of 29MW (40t / h), where

one set of 70MW (100t / h) is used as a backup boiler currently, and the existing heating

area is of 2,105,300 m2.

The heating pipes in urban area have quality problems.Most of the pipelines have the

problem of aging and corrosion, the pipeline leakage and blockage have seriously affected

the quality of heating; part of pipe materials are poor, and insulation materials are

damaged, and the quality problems of pipe fittings are getting increasingly serious.Due to

valve leakage, corrosion damage of compensator and the erosion of holders, failures of

heating system happened frequently, which seriously affected the heating quality.The lack

of overall planning and design of the pipe network, unreasonable pipeline laying coupled

with the significant changes occurred in heat load in recent years resulted the serious

disorders in the current pipe network hydraulic conditions and thermal condition. The

network systems of Level II lacks control facilities, which resulted in the uneven heating

and disorders of hydraulic conditions.

According the relevant issues of heating realities, the following issues are analyzed:

① The decentralized heating boiler room has low heating efficiency, big energy

consumption, poor quality and serious pollution.

② With the development of the Yixian County, the current heat source cannot meet

the needs of the heating load development.

Because of the above problems, the construction of heating pipe network expansion

project of centralized heating in Yixia County can save energy, reduce pollution and

improve the local environment.Upon completion of this project, the heating supply of

Yixian County will be undertaken by Jinzhou Guanda Heating Power Co., Ltd., which will

replace the 4 dispersing small boiler rooms in the heating area (five sets of small boilers)

to solve the problems of coal cinder dust produced by boiler room burning, the dust of

heap coal yard and boiler room noise nuisance; after the transformation of some of the

existing regional heat exchange stations, the land occupation can also be reduced.

Construction of this project brings not only economic benefits, but also the greater

environmental and social benefits.

3. Solid Waste

After completion of the project, the labor quota of 52 people will be increased, and

there will be garbage generation with the quantity of 19t/a.

3.5 ALTERNATIVE SOURCE

After the project is completed, five boilers and four small chimneys ( built in 2008 ~

2009 ) of four boiler rooms in Sunny Garden, Xinghua Garden, Happiness Garden and

Vocational High School will be dismantled. The heating areas of the above small boilers

10

are over 0.34 million m3, if central heating via heat plant is conducted, the heating

efficiency will be increased, and thus reduce coal burning of 3596t/a. Therefore, the

reduction of 3596t/a of fuel coal can result to the reduction of emission of sulfur dioxide at

86t/a, nitrogen oxides 55t/a and fume 50t/a.Huge improvement will be rendered to the

quality of the air and environment in Yixian urban area. The land left at the location of the

original small boiler room can be used to build greenbelt of other municipal public

facilities, which can improve the regional environment, and bring a certain degree of

social benefits for the Yixian County as well.The problems of burning coal cinder dust,

waste water, coal storage yard and boiler room noise nuisance resulted from the boiler

room can all be solved. The demolition plan for the small boilers is shown in Table 5-3.

3.6 HEAT PLANT

The central heating souce Jinzhou Guanda Heating Power Co., Ltd. is located in

Houyang Village, Chengguan Township, Yixian County, which covers an area of 35,000

m2, currently it has 43 regional heat exchange stations (including a heat exchanger station

within heating source plant), and the heating capacity is 215MW, with two sets of 70MW

(2 × 100t / h), 1 set of 46MW (65t / h), 1 set of 29MW (40t / h), where one set of 70MW

(100t / h) is used as a backup boiler currently, and the existing heating area is of 2,105,300

m2.For the central heating source projects, Jinzhou Municipal Environmental Protection

Bureau issued the "On the Official Reply of Environmental Impact Statement of Central

Heating Project in JunZhou Guanda Heating Power Limited Company in Yixian County"

(Letter of Environment In Jinzhou [ 2010 ] No. 74 ) in July 2010. The main pollutant

emission indicator and environmental measures of heat plants are as follows:

The 4 boilers in the heat plant share a 65m chimney; ceramic multi-tube dust cleaner

is used, and the dust removal efficiency is 95%; the lime- calcium sulfite method tower

wet desulphurization method is used with the desulphurization efficiency ≥ 90%; dust and

SO2 concentration is controlled by the II standard time limit control in "boiler air pollution

free emission standard"(GB13271-2001) (dust emission concentration 200mg/m3; SO2

900mg/m3), ringelman emittance is less than level I, coal with ash content <25%, sulfur

content of < 0.85% should be used; fully enclosed coal yard should be used, surrounded

wind wall should be used, and top is set with the tent and mist spray system , coal

11

handling system uses a fully enclosed corridor; the waste water produced by boiler river

sewage water treatment chemicals should be used in desulfurization and ash washed up

water, and domestic sewage is treated in Yixian sewage treatment plant after discharged

into septic tank treatment after processing through an urban water supply network; all the

boiler ash produced shall be subject to the comprehensive utilization by Jinzhou Yulian

building Materials Co., Ltd., a subordinate enterprise of Jinzhou Guanda Heating Power

Co., Ltd. ( production of hollow bricks ); temporary ash is stored in yard with seepage and

anti- dust measures; noise equipment must be installed in the plant with damping, isolation

sound, noise reduction measures; coal factory vehicle access is prohibited horning so that

factory noise standards can be reached.

The heat plant passed the acceptance of environmental protection for the completed

construction projects organized by administrative department of environmental protection

in March 2013.Heat plant is set with located gas-line device, and is currently applying for

environmental protection acceptance.According to the completion and acceptance contents

of heat plant environmental monitoring report, the total heat control pollutants allowable

in total plant emissions are: SO2 95.19t/a, dust 104.48t/a; actual emissions: SO2 94.01t/a,

dust 89.89t/a, which are less than total control indicators. Concentration of pollutant

emissions to the atmosphere is: SO2 177mg/m3, dust 169.9mg/m

(GB13271-2001).The concentration of SO2 emission has met the requirements of World

Bank thermal power plants Environmental, Health and Safety Guidelines (EHS), but the

dust emission concentration is higher than the requirements of World Bank thermal power

plants Environmental, Health and Safety Guidelines (EHS).Currently, the ceramic

multi-tube dust cleaner with the collection efficiency of 95 % is used in Guanda Heating

Power Plant; if dust removal system transformation is carried out as per the reference of

12

EHS standards, greater investment and increased operating costs will be rendered though,

and the implementing is much more difficult considered from the economic perspective.

4 Environmental Impact Analysis The negative environmental impacts of the project are summarized in this chapter,

and the information comes mainly from the environmental impact report in this project.

4.1 STATUS OF ENVIRONMENTAL QUALITY

( 1 ) Ambient Air Quality

According to 2012 Annual Report on Environmental Quality of Yixian, Yixian urban

ambient air quality is as follows:

Annual average of sulfur dioxide in Yixian County is 0.033mg/m3, which reached the

Level 2 Standard in "Ambient Air Quality Standard" (GB3095-2012).

Annual average of nitrogen dioxide in Yixian County is 0.064mg/m3, which exceeded

the 0.6 time of Level 2 Standard in "Ambient Air Quality Standard" (GB3095-2012).

Annual average of PM10 in Yixian County is 0.098mg/m3, which exceeded the 0.4

time of Level 2 Standard in "Ambient Air Quality Standard" (GB3095-2012).

The peak concentrations of the above main atmospheric pollutants mainly appear in

winter, which has a certain relation with the scattered small heating boilers within the city,

and the relatively higher nitrogen dioxide in each month throughout the year may be

associated with the increasing of motor vehicle exhaust emissions.

( 2 ) Quality of Acoustic Environment

Sound quality of the environment was measured by Yixian environmental monitoring

stations from 22 July 2013 to 23 on the status of the noise in Yixian; the measurements

was carried out once at day and night respectively, which was 10:00 at daytime, and 22:00

at night. Noise monitoring results are shown in Table 4-1.

Status value of each noise monitoring sites can meet the standards of "Environmental

Quality Standard" (GB3096-2008).

4.2 ENVIRONMENTAL IMPACT ANALYSIS DURING

CONSTRUCTION PERIOD

( 1 ) Atmospheric Environmental Impact Analysis

The dust generated in the construction is a major air pollution environmental problem,

it mainly generated in earthwork excavation, piling, material transport, road demolition,

earthwork backfilling, pavement restoration and during vehicle transport; fuel emissions

produced in the construction machinery, and the main emitted pollutants are CO, NO2.

In the construction site with the wind speed ≥ 3.5m /s and relative humidity ≤ 60%,

the dust impact strength and scope is listed in Table 4-2.

Table 4-2 Impact Degree and Scope of Construction Dust

field distance m 10 20 30 50 100

Dust concentration

in mg/m3

10.14 2.89 1.15 0.86 0.61

Construction site dust is mainly produced by transport vehicles, accounting for 60%

of total dust, and is related to the road surface and the speed of the vehicle; under normal

circumstances, the impact scope of construction site and construction of roads under the

effect of natural wind is within the range of 100m.

During the construction, the road with the vehicle driving should be sprayed with

water to suppress dust, which can reduce dust by 80 %. The dust impact after the

construction site dust suppression sprinkler is shown in Table 4-3.

14

Table 4-3 Dust impact after the construction site dust suppression sprinkler

field distance m 10 20 30 50 100

Dust concentration after

watering in mg/m3

2.01 1.40 0.67 0.27 0.21

Table 4-3 shows that the watering on the construction site and roads for transport can

effectively prevent dust, and the dust concentration in the 50m is of 0.27mg/m3, which can

meet environmental standards.

Due to the shorter construction period, and under the circumstance that the

construction unit took the above measures in the construction process, the impact of

construction dust on surrounding residents is smaller. And with the end of the construction

period, dust impact will disappear.

（2）Water Environmental Impact Analysis

Sewage generated by construction workers on site is the main sources of water

pollution during the construction period of the project. For the different stages of the

construction period, the construction numbers typically ranges from dozens of people; if it

is calculated by 50L / person • d for the daily domestic water consumption of construction

workers, and the amount of sewage generated is calculated as 80% of the total water

consumption, then the average person discharge sewage is 40L / person per day. CODcr

generated by analogy was 240mg / L, BOD5 was of 150mg / L, ammonia was of 25mg / L.

During the peak construction, the project construction site sewage and pollutant emissions

per day are shown in Table 4-4.

If the above domestic sewage is directly discharged, it will pollute the water

environment where the area is; therefore, construction workers should try to take

advantage of nearby health facilities, canteens sewage settling ponds of oil removal and so

on, due to the short construction period, basically no impact will be imposed to water

environment where the area is.

( 3 ) Solid Waste Environmental Impact Analysis

The solid waste generated during the construction period of the project are mainly

15

domestic waste generated by construction workers, and the construction waste generated

during the construction period, such as packaging bags, construction scraps and waste heat

network cables etc.The domestic waste is processed at the urban waste yard after waste

collection. The packaging bags, construction scraps and waste heat recovery network

cables shall be recycled by the construction unit.

In this project, the excavation earthwork is 38×104m

3, and backfill earthwork is

34×104m

3 and the excess earthwork is 4×10

4m

3. Currently, many real estates in Yixian are

under construction, which demands for larger earthwork; and the excavated spoil in this

project will be used as construction fill, which will not be discharged.

The small boiler as a replacement in this project was built in from 2008 to 2009, when

asbestos is no longer used as an insulation material, but the old pipeline was built in the

1990s, as part of it still use the asbestos as the insulation materials, a series of measures

should be taken to prevent an impact on the environment caused by the asbestos removal,

as shown in Table 5-1. When asbestos materials are found in removing small boilers, it

should also process as the disposal method of asbestos in accordance with Table 5-1.

All solid waste generated during the construction period of the project can be

effectively recycled or disposed of, which causes less impact on the environment.

( 4 ) Acoustic Environmental Impact Analysis

During the construction period, the main machinery such as the excavators, rollers

and trucks will produce loud noise. The noise of main construction machinery and

equipment is shown in Table 4-5.

Table 4-5 Noise of main construction machinery and equipment

No. Name of construction equipment average noise level 10m from the equipment

[dB (A)]

1 Excavator 82

2 bulldozer 76

3 cranes 82

4 Road Rollers 82

5 heavy trucks 85

Construction noise impact on the surrounding area acoustic environment should be

evaluated by using the "Construction Site environmental noise emission standard"

16

(GB12523-2011); and the standard value is daytime 70dB (A) and nighttime 55dB (A).

Take the heavy-duty trucks in Table 4-5 for example, which has the highest noise level,

the situation of its reduced operating noise after the distance is increased, as shown in

Table 4-6.

Table 4-6 Attenuation values of Construction Noise with the Distance

Distance (m) 1 10 50 100 150 200 300 400 500

Noise level [dB

(A)] 85 65 51 45 41 39 35 33 31

The noise generated by construction will have a greater impact on the first row of

buildings of residential areas, school, along the road construction pipes which are near the

heat exchange stations. To prevent construction noise impact on residents at nighttime,

construction at nighttime is prohibited at noise sensitive areas of residential areas and

hospitals etc; known from the calculation of the results in Table 4-6, the exceeding area of

daytime construction machinery noise is within 10m. In addition, the construction period

of the project is relatively shorter; the using time of various types of construction

machinery is also shorter. With the end of the construction, the impact on the environment

will disappear, therefore, the impact on the acoustic environment caused during the

construction period of the project is less.

( 5 ) Traffic Impact Analysis

The impact on traffic caused by the project during its construction period is mainly

reflected in the construction part of the pipeline, which is shown in the following three

aspects:

Broken pipeline construction road will hamper traffic;

The excavation of earth piled up and roads will hamper traffic;

The increase of transport vehicles will increase the traffic on the road.

Pipeline construction will cause some impact on road traffic, although the stage

construction methods can be adopted, some earthwork in the construction process still

needed to be temporarily piled up, which will pose impact on traffic along the road of

pipeline construction. When the pipeline pass through the road, the slotting method should

be adopted for non-main road, and it’s easy to make the vehicles on the road blocked,

17

which will pose a greater impact on traffic conditions, but the average construction time of

the pipeline crossing the road is no more than seven days, so the impact of pipeline

construction on traffic should be controlled within 7 days. The pipeline laying in this

project is carried out mainly on the sidewalk with closed construction, and then no vehicle

diversion or obstruction would occur, which would not pose affect on the road traffic.

However, the construction time should be reduced, and the residents should walk

frequently on the road and residential areas as possible to prevent interference of residents

going out. For the impact on the street shops and pedestrians, the temporary access and

exit can be set with the timely public announcement of bypassing, and enclosure should be

set to protect the safety of pedestrians.

The traffic amount in this project is not big, and there’s no centralized transportation,

so little impact will be caused on city traffic.

( 6 ) Ecological Impact Analysis

The designed excavation width of pipeline is 2.5m, and pipeline construction

temporary occupation of land is about 29.5hm2, both are open space and sidewalks along

both roads. The construction process does not destroy the green space, due to the short

construction period, the land occupation is temporary, after the end of construction, the

situation of land occupation will come to an end. All pipes are laid under the ground,

without passing through the sensitive environmental goals such as the scenic spots, nature

reserves and so on.

Among the newly built 27 heat exchange stations (including 10 heat exchange

stations) in this project, 11 of which are proposed to set up in the buildings, and the other

16 heat exchange stations take a land occupation of about 2600m2, and the occupation is

mainly the unused land near the school and the newly built community.

After the completion of the project, the greening and beautification work around heat

exchange station should be done; should the vegetation is destroyed in the construction, it

should be restored to its original appearance after the end of the construction period as

soon as possible.

( 7 ) Pipeline Risk Analysis

Pipeline construction is located in one side of the city trunk roads, and municipal

pipe network are under both sides of the ground (water and drainage network).The main

18

risk factors during the construction period are improper construction, resulting in breakage

of the municipal pipe network and leaks thereafter. Currently, there is no gas pipeline

network in Yixian County, so the construction will not bring the environmental risks of

gas pipeline leakage.

Prior to the construction, the construction program should be confirmed with the

municipal water and sewer pipe network management departments to ensure that the

heating pipe network construction would not affect it.

( 8 ) Impact Analysis of Pipeline Across the River

The pipeline construction project would pass through 3 sections of the artificial river,

in which one is erected along the bridge bottom, and two are adopted with the river

excavation method. Artificial river is the flood control project for the Daling River in

Yixian. The river length is 5080m, at present, the urban section is undergoing the

comprehensive management project, and the river sections through which the project will

pass is currently in the dry state. If the river way is excavated when there is water in the

river, the slurry produced will have an adverse impact on the artificial river water, but also

a certain extent on the river sediment and aquatic organisms in rivers and ecological

environment. At this time, rivers closure should be made to assure no impact would be

rendered to the water. Construction time should be selected in the winter or dry season,

which can reduce the impact of construction on the river and aquatic organisms. In

addition, the construction process time should be minimized in the river.

4.3 ENVIRONMENTAL IMPACT ANALYSIS DURING

OPERATION PERIOD

Acoustic Environmental Impact Analysis

Most of the heat exchange stations drafted to be transformed and newly built in the

project are located in residential areas at noise-sensitive points, and the equipment noise

generated by heat exchange station may have some impact on the surrounding residents.

Noise pollution control measures to be taken in heat exchange stations are listed as

follows:

19

All heat exchange stations are required to select high-quality low-noise equipment,

and the noise source strength of building heat pump station shall not exceed 55dB

(A);

Noise equipment should not be connected with building body;

The damping foundation base should be done, and shock absorbers should be installed

to reduce sound transmission from vibration; pump inlet and outlet should be

connected with a rubber hose; additional concrete base should be set at the bottom of

the heat exchanger unit, and additional damper should be set between the base and the

ground and the walls to eliminate the impact of low frequency sound outside the

structure.

( 1 ) statistics of status quo of the acoustic environment around heat exchange stations

The project includes 17 newly built regional heat exchange stations and 10 building

heat exchange stations at Junyu Huating Community, which is intended to use the location

of existing four demolished boiler rooms to build 2 #, 3 #, 4 # , 17 # region heat exchange

stations.

Noise would be generated in the process of heat exchange stations running, which

would pose impact on the surrounding environment sensitive points within a certain

range.17 regional heat exchange stations and 10 building heat exchange stations of Junyu

Huating Community in this project area are planned to be built in the vicinity of

residential and office buildings, among which, 9 of the building heat exchange stations in

10 of Junyu Huating Community are set in residential buildings, one is in the integrated

building of the community (complex building includes distribution room and property

management office). For these unbuilt heat exchange stations, the EIA shall propose

control requirements concerning the distance and construction form between the heat

exchange stations and noise-sensitive buildings.

( 2 ) Noise Prediction at Heat Exchange Stations

1 ) Statistics of noise emission sources strength

According to heating area and building height of various heat exchanger stations, the

heat exchanger unit types in this project will be divided into three kinds, each heat

exchanger unit noise equipment is: 1, three circulating pumps and one constant pressure

20

water pump station (Newly built 7 #, 16 #); 2, two circulating pumps and one constant

pressure water pump station (Newly built # 1 , # 2, 6 #, 9 #, 10 #, 11 #, 12 #, 13 #, 15 #,

and # 2); 3, one circulating pump and one constant pressure water-make up pump (newly

built 3#, 4#, 5 #, 8 #,14 #, and 17 # )."Cold standby" mode shall be used for both the water

circulating pump and constant pressure water make-up pump for each heat pump station,

that is the water circulating pump and constant pressure water make-up pump of the same

type will be stored in the station respectively as a backup. According to analog data

provided by equipment manufacturers, after taking damping measures, interior noise

source strength when the noise devices are operating is shown in Table 4-7, and the

outdoor noise sources strength is shown in Table 4-8.

3 ) Environmental Protection Measures Taken

To reduce the noise generated by heat exchange station during operation period, all

the noise equipment of circulation pumps and water make-up pumps for 17 newly built

regional heat exchange station of the project are arranged under the ground; according to

23

the analogy analysis, if the noise equipment is arranged under the ground, then the noise

source strength at heat exchange station can be reduced of 25dB (A). In addition, among

10 newly built building heat exchanger stations, one is set up in the complex building

(complex building includes distribution room and property management office) of the

community proposed to be built, heat exchange stations are set up in the position more

than 15m from residential buildings; and the heat exchanger units of the other nine

stations buildings are set up in the first floor of each residential building; according to the

current architectural design, the first floor residential building is the garage or shop to

prevent noise impact on residents; the rock wool board of the internal and external walls

of heat exchange station and the room top will be thickened one time, and

sound-absorbing composite panels of the size 2 × 15mm will be added to the top of the

room and internal walls; sound-absorbing composite panels of the size 1 × 15mm for the

external walls and insulation board of 70mm will be set outside the building with the

installation of soundproof windows and doors, and the sound level at 1m outside the

structure of the outdoor maintenance should be controlled at the level ≤ 35dB (A).。

4 ) Acoustic environmental impact analysis of heat exchange station

Under the condition that the noise source of regional heat exchange station is set

under the ground and noise reduction measures have taken for the 1 # to 9 # building heat

exchange station rooms, and the noise source strength statistics is shown in Table 4-9.

Table 4-9 shows that after the noise equipment is set under the ground, the noise

contribution values at the heat exchange stations to the ambient environmentally sensitive

construction can both meet the daytime and nighttime values Class 1 standard in acoustic

environment; after the measures of thickening of walls and floor slabs, installation of

sound-absorbing materials as well as sound insulation windows and doors for the building

heat exchange station installed in 9 residential buildings, there is basically no impact on

the residents.

Table 4-8 shows that, sound level at 1m of 10 # station outdoor maintenance structure

of the building heat exchanger unit station is 35dB (A). By analogy analysis, if the

distance between the heat exchange station and residential buildings is more than 15m,

and considered from the perspective of vibration, noise etc, the impact on the residents

from the heat exchange stations are smaller.

The detailed environmental protection measures to be taken for the heat exchange

station are listed in Table 5.2.

( 3 ) Conclusion

On the basis of taking the above environmental protection measures of shock

absorption, noise reduction, the heat exchange station in this project would basically pose

25

no impact on the sensitive buildings around the residential buildings during its operation

period.

2. Water Environmental Impact Analysis

9.1.7 Conclusion of Public Participation

EIA is conducted by publishing in the newspaper and website, posting

announcements, and the issuance of public participation questionnaire for public

participation. No feedback was received during the public notice. Among the 50

copies of public participation questionnaire issued, 50 valid questionnaires were

collected, of which 100% public support for the construction of the project.

During the investigation, some of the public comments and suggestions were

collected:

( 1 ) It is hoped that after running the project by the environmental protection

department, supervision and management of the enterprise's environmental protection

operation shall be strengthened to meet environmental requirements.

( 2 ) The construction units shall strengthen the management of the environment,

and set up specialized environmental agencies and personnel for the regular inspection

and maintenance of environmental protection facilities; while they shall often visit the

public around for communication and resolve of newly arisen situations and

problems.

Therefore, EIA requires that building units should, in the preparation process,

placed the work of environmental protection in an important position:

Construction units shall strictly implement the pollution control measures in

the construction period proposed in the report, and reasonably arrange for the

construction site and construction time to minimize the impact on residential

areas during the construction process.

departments shall strengthen the supervision and management of operation of the

enterprise's environmental protection; the construction unit shall strictly enforce

the pollution control measures proposed in the EIA report.

The construction unit shall set up specialized environmental agencies and

51

personnel and conduct the regular inspection and maintenance of heat exchange

stations and pipeline; while frequently visit the relevant public to keep aware of

their views.

It is understood through statistical analysis of questionnaires and visits to

relevant public that the vast majority of the public believe that the implementation of

this project can replace the small boiler within the heating supply area, improve urban

air quality and the quality of urban heating, which should be implemented as soon as

possible.
