4.1.2 Topography, geomorphology, and geology
Wanzhou is located at the eastern folded belt zone in Sichuan Basin, which is composed of
Jurassic sandstone and mudstone layers with unequal thickness, with Yangtze River across
its southern area and Fangdou Mountain at its southeastern comer. This parallel
ridge-valley region contains high mountains with steep hills as well as crossed ravines. In
general, the topography is varied and complicated.
Landslide, dangerous rock, collapse, debris flow, and other unfavorable geological
phenomenon were not found within the scope of this project site. The status of the slopes
along the riversides is stable. The ground bearing stratums are composed of mudstone and
sandstone with a shallow and stable distribution, which is suitable for project construction.
4.1.3 Meteorology
Wanzhou is situated in the region where the semi-tropical climate dominates. The climate
is warm and humid with large amount of precipitation. The annual temperature ranges
from -1.8 ℃ to 42.3 ℃ with an average of 18.1 ℃. The average annual frost-free period is
314.9 days with 30 to 40 fog days. The average annual precipitation is 1191.30 mm (the
highest precipitation was 1577.30 mm in 1993). The precipitation varies largely with
different months, with 70% being distributed in the rainy season from May to September
each year. The highest monthly precipitation was 711.9 mm (Jul 1982); the highest daily
precipitation was 175.00 mm; and the longest continues rainy period was 16 days.
4.1.4 Hydrology
12
The domain within Wanzhou contains abundant surface water resources, while the
groundwater is relatively deficient. The water area is 24.07 km2 and accounts for 10.1% of
the total area.The network of rivers is intricate and most rivers feed into Yangtze River.
The groundwater is in general fissure water or seepage water. According to the
precipitation brought by the subtropical monsoon, a clear trend of runoff adapt to the
precipitation exists. The seasonal distribution of the annual runoff is: 26.7% for spring;
40.2% for summer; 28% for autumn; and 5.1% for winter. Yangtze river travels across
Wanzhou from the southwest to the north through 17 towns and administrative offices with
the total length of 83 km. The average annual flow rate is 12913 m3/s; and the average
annual flow volume is 450 billion m3.
This report uses the monitoring data on Saiwangba Section of Changjiang River from
Wanzhou Environmental Monitoring Station on Sep 2012, which indicates that the index of
pH, COD, BOD5, NH3-N, petroleum, and fecal coliform is less than 1, which meets the
class III standard of Surface Water Quality Standard (GB3838－2002).
4.1.5 Acoustic environment

4.2.3 Transportation
The 3-dimentional traffic network of water, road, and air has been gradually formed. The
length of Wanzhou highway has reached over 1500 km (excluding the village road). The
Wanzhou Yangtze River Bridge and the Yangtze River Second Bridge have been built. The
construction of highway was completed and now only 3 hours are needed from Wanzhou
to Chongqing. The railway from Dazhou to Wanzhou has been constructed and opened for
freight and passenger transport. The special railway line from Hongxigou pier to Wanzhou
railway station has a transport capacity of 2 million t/a, which can connect the railway to
the water carriage once completed. Of molten iron transport can be realized. Wanzhou
Wuqiao airport has been open to air traffic in May 2003. One third of the construction of
the 15-million-ton port has been completed as planned. After the completion of the Three
Gorges project, ton class vessels and fleets can be directed into Wanzhou port. The
expressway from Wanzhou to Kaixian and Yunyang has been built and open for
transportation. With improving transport conditions, a network of convenient water, road
and air transportation will be formed with sound function and rational layout in Wanzhou.
4.2.4 Cultural relics
Wanzhou has many institutions to protect the cultural relics, including 56 first-group
district-level institutions, 20 second-group district-level institutions, 34 third-group
district-level institutions, and 17 forth-group district-level institutions. There is no
institution for cultural relics protection within 500 m of this project.
4.2.5 Urban planning
14
According to the document “A Decision by CPC and the Chongqing People’s Government
to Develop Wanzhou into One of the Second-largest Cities” (CMG [2010]16), Wanzhou is
one of the most important and largest cities to develop in Chongqing’s urban-rural
integration development project, and an important gateway for economic development in
northeastern Chongqing and three gorges reservoir area. It is also a barrier for stability and
ecological safety in the reservoir area.
By 2015, Wanzhou will be the central city in the three gorges reservoir area with an urban
area of 80 km2 and a population over 1 million. The regional GDP will be more than 100
billion and the average GDP per capita will be close to that of the main city. In the next
5-10 years, Wanzhou will see rapid development of urbanization.

5.2 Environmental Impacts and Mitigation Measures
5.2.1 Environmental Impacts and Mitigation Measures in Construction Phase
① Air Pollution
The air pollution during the construction stage will be caused by the air-borne dust
generated from excavation, construction waste and material transportation, leading to
deterioration of air quality. Area affected by fugitive dust is within 150m of downwind
construction site when the wind speed is at 2.0m/s, which concludes the air pollution in
west and north of the project will be comparatively greater but to be eliminated when
project completed.
15
Air pollutant mixed by CO and NOx generated by fuel machine for excavation and fill,
transportation and construction will have minor impact because the fuel machine works
intermittently at night in earthwork excavation stage resulting in little discharge.
Pollution impact to be eliminated when work completed. Liquefied petroleum gas as
green energy to be used by workers has little impact on environment.
② Surface Water
The construction wastewater is mainly generated from domestic waste from works and
wastewater on site. Construction wastewater contains SS, petroleum element generated
by equipment maintenance, cleaning, and concrete curing.
Construction wastewater will be recycled after treatment though grease trap
sedimentation. The domestic wastewater will be collected then discharged into
municipal pipe network in the south of project site. The wastewater impact is
eliminated as work completed.
③ Noise
The primary noise source in construction phase is the operation of equipment, having
negative impact on the sensitive spots around of project site.
④ Solid Waste
Solid waste in construction phase is mainly generated by earth disposal, construction
waste and domestic waste from workers. It will have negative impact on cityscape and
sanitary condition if it’s not removed timely; it even will cause water and soil loss in
rainy day. The solid waste shall be firstly piled by sorting out then removed timely with
preventive measures taken so as to avoid water and soil loss. Construction waste shall
be moved to the designated spoil site, and domestic waste shall be moved to landfill
site.
⑤ Water and Soil loss
Earthwork excavation and ground leveling will loosen land surface to possibly cause
water and soil loss in raining day.
⑥ Transportation
As the construction site will have engineering vehicles access frequently (through
Longyuan Rd in northwest of site, and municipal road in south of site), the vehicles are
required to be washed before leaves, and no earth rock falling out as vehicles travels on
road. Solid waste transportation must follow “Notice on leak-proof transportation of
substances easily spilt in main city” and “Management Regulation on Construction
Waste Removal in Main Area of Chongqing”(No 93 document issued by CMG). These
measures will have effective control of pollution caused by solid waste transportation.

5.2.2 Environmental Impacts in Operation Phase
5.2.2 .1 Air Emission
① Emissions from Boilers
This project plans to set a gas-fired boiler to supply steam for the operating room,
laundry and other clean areas; and a gas vacuum hot water boiler for heating and hot
water.
Both boilers use gas and the combustion emissions should be merged and discharge
from a stack higher than 8 m. The limit for SO2 is 3.2 t/a, and the discharge
concentration should be lower than 51 mg/m3; the limit for NOX (converted to NO2) is
9.3 t/a, and the discharge concentration should be lower than 150 mg/m3; the limit for
dust and fume is 1.5 t/a, and the discharge concentration should be lower than 25
mg/m3, as required by “Air Pollution Emission Standards for Boilers”
((GB13271-2001)).
Since gas is a clean energy, the contaminate concentration is low and has minor
influence on the air.
② Cooking Oil Fume
The cooking oil fume from the canteens will bring negative impacts to the air, thus it is
necessary to purify the oil fume before discharging. Suppose the remove efficiency
reaches 85%, the oil fume concentration will be about 1.0 to 1.8 mg/m3, which meets
the requirement of “Emission Standard of Cooking Fume” (GB18483-2001) and has
minor influence on the air quality.
③ Wastewater Treatment Station Odor
This project plans to build a 450 m3/d wastewater treatment station at the south part,
which may produce odors by methane, ammonia, and hydrogen sulfide.
The assessment requires the station to be enclosed by cover plate with reserved
inlet/outlet. The collected odor should be treated with activated carbon and discharged
through specific pipelines to the green belt. The discharge outlet is 65 m away from the
Wanzhou No.3 People’s Hospital at Baolong, 55 m away from the southeastern
residential building, and 45 m away from the west residential building. The odor
influence will be reduced after the treatment.
18
④ Vehicle Exhaust
The vehicles can produce a certain amount of exhaust, thus it is necessary to set a
double-speed fan in the garage, of which the ventilation rate is no less than 6 times per
hour. The exhaust should be directed to the exhaust shafts and discharged at the roof.
The impact to the air quality is minor.
⑤ Backup Generator Exhaust
A mechanical discharge device is set up in the backup generator room. The exhaust
should be directed to the exhaust shafts (use refractory bricks for thermal insulation)
and discharged at the roof. The impact to the air quality is minor.
5.2.2.2 Surface Water
① Hospital Wastewater
According to the engineering analysis, the flow of the hospital wastewater is about
413.38 m3/d. The major components include: organics, SS, grease, pH, toxic chemicals,
pathogenic bacteria, viruses, and parasitic ovum, etc., thus it must be discharged after
sterilization and treatment.
A municipal pipe network (DN600mm) is set 160 m south from the site. The first phase
capacity of Minjingtan wastewater treatment plant was planned to be 30,000 m3/d,
using A2/O oxidation ditch process ((anaerobic-anoxic-aerobic carrorsel oxidation
ditch). The discharging water can meet the first level class B standard of “Urban
Wastewater Treatment Plant Pollutant Discharge Standard”. This plant was completed
on Jul 2003 and has been under stable operation. The actual capacity is about 10,000
m3/d, and can accept the wastewater of this project. Chongqing Yudong Water CO.
LTD has agreed to accept the wastewater after pretreatment of this project.
This project plans to build a wastewater treatment plant with the capacity of 450m3/d
and the treatment process of primary treatment + disinfection. After treatment, the
hospital wastewater will meet the primary treatment standard of “Water Pollutant
Discharge Standard for Medical Institutions” (GB18466-2005) and be discharged into
the Mingjingtan wastewater treatment plant through the municipal sewage network.
② Special Wastewater
This project adopts digital X-ray fluoroscopy devices. There is no photo development
room and liquid waste containing silver. According to related operation information, no
radioactive liquid waste is produced by the radiology department.
The silver amalgams used by the stomatology department are purchased and sealed in
19
capsules, thus will not generate wastewater containing heavy metals. The silver
mercury residues are stored by ground-glass stoppered flasks for manufacturers
recycling.
The wastewater of clinical laboratory may contain toxic substances such as chromium,
and cyanide with the amount about 0.5 m3/a. The amount of the special wastewater is
small, which is difficult for treatment and cost is high. The project incorporates the
waste water into the medical waste and uses special airtight container to collect the
pollutants for Wanzhou Senhao Pollutant Disposal Limited to dispose.
As long as this project can strengthen the operation and management of wastewater
treatment facilities and the workers’ environmental protection consciousness, and
ensure the reasonable management and control of special wastewater discharge, the
concentration of medical pollutants will be reduced and will not bring negative impacts
to the the Yangtze river.
5.2.2.3 Noise
The major sources of noise are pump house, cooling tower of air condition and fans,
backup generators, and vehicles. The equipment and intensity are listed in Table 5-3.

The noise control measurements for various sources:
① Vehicles
The garage is in the two basement floors, thus the noise can be removed using its
location. The basement sound insulation capacity can reach to over 40 dB(A). After the
insulation, the basement garage sound insulation will not produce very large noises.
The garage on the ground can reduce the traffic noise by setting slow-down and silence
identifications. From these actions the traffic noise can be effectively controlled and
will not have great influence to the outside world.
② Cooling Tower
The noise produced by the cooling tower noise are mainly caused by the fan and
chimney, and the noise is about 80 dB(A). Noise reduction measures include: use a
shock absorber and rubber soft materials to reduce the effects of vibration; install a
20
muffler at the cooling tower inlet/outlet; use an anechoic water cushion and control
water muffler to control the noise; set up sound barriers outside the cooling tower.
③ Pump Room, Fan Room, and Power Room
Pump room, fan room, and power room are at the first level of the basement. From the
insulation of the walls, the noise can be reduced up to 40 dB(A), thus won’t influence
the environment.
5.2.2.4 Solid Waste Impact Analysis
① Medical Waste
The germs in medical waste are tens or even hundreds times more than the ordinary life
trash, and most dangerously, it is infectious.
Before taking the medical wastes, the packages or containers should be carefully
checked to be without damage, leakage, and other problems; it should also be
registered to prevent loss. The cultures for pathogens and bacteria, the specimen and
strains, the virus seed preserving liquid, and other medical wastes must be primarily
treated before transporting to the disposal institutions. The temporary storage facilities
and equipment regular cleaning and disinfection should meet the requirements of
“Hazardous Waste Storage and Pollution Control Standards” (GBl8597-2001) and
“Technical Specification FOR Medical Waste Centralized Disposal”.
The medical waste storage room is located at the south of this project, away from the
medical area, personnel activity area, and living area. The medical waste storage room
is separated from the domestic refuse temporary storage spot. The washing wastewater
of the medical waste storage room can be directly discharged into the wastewater
treatment plant. The medical waste on different floors can be collected by specified
containers and transported through specified channels to the storage room through the
south channel. The channels for waste transport are separated from the patients and
doctors. The medical wastes are collected, transported and disposed by Wanzhou
Senhao Pollutant Disposal Limited.
② Sludge from Wastewater Treatment Plant
This project intends to set up a sludge concentration pool and a disinfection pool. The
sludge that meets the requirements of "Water Pollutant Discharge Standard for Medical
Institution" (GB18466-2005) will be dealt with by Wanzhou Senhao Pollutant Disposal
Limited.
③ Household Refuse
The trash will be collected by class and transported to the municipal landfill sites.
④ Food Waste
The food waster will be dealt with by specified institutions with related certifications.
21
⑤ Special Wastewater
Clinical laboratory wastewater will be temporarily stored by specified airtight container
and sent to Wanzhou Senhao Pollutant Disposal Limited.
⑥ Waste Activated Carbon
The waste activated carbon that has absorbed the odor from the wastewater treatment
plant will be sent to Wanzhou Senhao Pollutant Disposal Limited.
5.2.2.5 Radiation Impact Analysis
According to the analysis, after the completion of the project, the annual effective
additional dose of the hospital radiation workers and the public are far less than the
limits of 6 mSv/a and 0.1 mSv/a, which meet the "Ionizing Radiation Protection and
Radiation Source Safety Standards" (GB18871-2002).
5.2.2.6 Social Impacts during Operation period
The increased traffic volume of current north, west and south municipal road is far
from its full load. The assessment reports show that the impacts to the current north,
west and south municipal road will be very little, and will not result in traffic jam, but
may have some negative impacts on the residents and students’ safety around
Longyuan Rd and the south municipal road. The prevention and control measures are:
Communicate with the management department, set school and hospital
identifications on the municipal road.
Set slow-down and silence identifications at the hospital entrances/exits.
6. ANALYSIS OF ALTERNATIVE PLAN
6.1 With or Without the Project
6.1.1 Without the Project
Three Gorges Reservoir Area is prone to epidemic disease and natural disaster, which leads
to difficult and arduous task of disease prevention and control. Currently the distribution of
medical resource in Wanzhou District is unbalanced. In the area where the head office of
Wanzhou Maternal and Child Hospital is located, the health care resources are concentrated,
which may lead to oversupply of the resources in a small area but insufficient in the whole
district.
If no further expansion of addition to the head office of Wanzhou Maternal and Child Hospital
(i.e. without the project), the current problem as regards medical resource in Wanzhou is to
worsen with ever increasing medical need of local people.
22
6.1.2 With the Project
The proposed project will :
① meet the needs of the Chongqing urban rural integration campaign；
② promote the development of medical health care in Wanzhou;
③ optimize the distribution of medical resources in Wanzhou District；
④ ensure that the public medical service of central cities in Three Gorge Reservoir will
be radiated to surrounding area;
⑤ ensure the health of local people.
The conclusion following the above comparison is that the proposed project will promote
the development of Wanzhou District medical service, ensure the medical service in
regional center be conveyed to surrounding area, improve the urban rural medical system
nd medical service, meet the needs of the people in Three Gorges Reservoir Area by
delivering safe, effective, convenient and local cost basic medical heath care service, and
ensure the health of local people. Therefore, the proposed project is necessary and urgent.
6.2 Site selection/ comparison
Three sites were proposed:
① Parcel C-01-33、C-01-10 included in the “Master Plan for Tiancheng Group I,II
Management Area(Tiangfang, Dongjia) ” located in Maogu Village 8 in Tiancheng
Town;
② Jianfengling of Wuqiao District;
③ Wanquan Community in Shuanghekou;
Based on the nature of the medical service to be delivered, the site condition and
environmental impact, Wanquan Community in Shuanghekou was selected as the best
project site.
6.3 Selection and Comparison of Disinfection Process
6.3 .1 Selection and Comparison of Disinfection Process
The following findings were made after comparison:
① For the method involving ozone generator and ultraviolet, one-off capital investment is
huge and operation management is complicated;
② For the method using bleaching powder concentrate, disinfectant and bleaching
powder, operation cost is too high;
③ For the method using liquid chlorine, the technique is mature and it is very effective,
but it is too dangerous and prone to leakage. In addition the one-off investment is no
less that of Chlorine Dioxide Generator method and toxic substance may be resulted
due to reaction with organics;
④ Sodium hypochlorite generator is bulky and its key components is easy to damage, the
23
electricity and salt consumption is high, and the operation is not convenient.
Currently Wanzhou Maternal and Child Hospital is a Category A of Class II hospital(with 500
hospital beds designed). The target of the proposed project is to upgrade it to a Category A
of Class III hospital(with more than 500 beds) integrating medical treatment and medical
care. The method of Chlorine Dioxide is proposed for disinfection.
6.3 .2 Selection and Comparison of Disinfectant Preparation
① Chlorine Dioxide Generator
Following comparison, NaCl diaphragm electrolysis method will be adopted, but it
must meet the requirement specified in ”Technical Specification of Environmental
Protection Product: electrolysis chlorine dioxide synergistic disinfectant generator”
(HJ/T257-2006).
② Alternative method in case of accident
In case of the breakage of disinfection equipment or other accident, the EIA requires that
all the medical wastewater be collected into the emergency tank, to be treated with
bleaching powder (sodium hypochlorite).
6.4 Comparison and Selection of Wastewater Treatment Process
The proposed site is in the service area of Mingjingtan WWTP and municipal wastewater
pipe has already been connected to the site. The wastewater from the project, which is to
be treated with enhanced primary treatment plus disinfection, will meet the requirement as
regards primary treatment specified in “Discharge standard of water pollutants for medical
organization (GB18466-2005)” , therefore the wastewater treatment proposal is feasible.
7. RESETTLEMENT PLAN
According to the field survey, there are no residential buildings within the project
construction area. The land-use right belongs to Wanzhou District Water Supply Company ,
Wanzhou Renyang Construction Material Shop, Wanzhou District Broadcasting Television
Station and Longbao Branch of Wanzhou District People’s Hospital. The project owner has
completed related land acquisition procedure. The Land Acquisition and Resettlement
Office under Wanzhou District Government will be responsible for the land acquisition and
resettlement. And the clean land will be handed over to Wanzhou Maternal and Child
Hospital. Therefore; there will be no land acquisition and resettlement under this Project.
