1 Project Description

1.1Background of the Project

Yingkou City Gas Company was founded in1986, which is the only pipe-gas public

utility enterprise in Yingkou. The resource of the company is natural gas from Liaohe Oil

Field. It has been transferred to the gas source plant located at Laobian District, Yingkou

City, via a 45-km pipeline from Liaohe Oil Field. After the pressure adjustment, it has

been sent to the whole city. The pipes and gas tanks have been aged after many years’

usage and the gas system is unable to meet the request of the expanding city of Yingkou.

Since then, the city’s gas system needs to be updated; the energy consumption of the

city needs to be optimized in order to assure the city’s demand. The pipelines of the gas

system of Yingkou have been using for many years; the geological condition of the city is

not good enough; the accessory is not enough; the rate of gas loss keeps at high level; and

there are some serious hidden trouble in the system. So Yingkou City Gas Company takes

out this project.

The route of the pipeline and location of Yingkoou Coal Gas Company are described

as figure 1-1.

1.2Name, Location, Nature, and project plan

Name: Reconstruction and Expansion Project for Gas Facilities of Yingkou City

Location: Yingkou City

Loan and the other from self-funded

Construction Plan: September 2008 – November, 2009

1.3Construction Contents of Project

Three contents in this construction project

1. Overhaul of the wet-style storage cabinet of the gas source plant (one is 20,000

m3, the other is 50,000m3) and build a new dry-style storage cabinet (50,000 m3)

2

2. Set up an intelligent gas management system

3. Gas pipeline rehabilitation: rehab of 9km natural gas transmission pipeline

(DN200), upgrading of middle pressure pipeline of 20km (DN200-DN300) and of low

pressure pipeline of 15km (DN200). Rehabilitation of 20 (middle pressure) and installing

of 40 (low pressure) new valves, and build cathodic protection system of about 280 poles.

The details is as followed,

1.3.1 Overhaul and building of storage cabinets in the gas source plant

Overhaul for the wet-style storage cabinet of the gas source plan (one is 20,000 m3,

the other is 50,000m3), including:

Change the rotten steel board;

Amend some of the wall board;

Adjust tower guide pulley;

Stabilize the entrance and exit of the pipes.

Besides, build a new dry style storage cabinet of 50,000 m3 at the free space in the

gas source plan.

1.3.2 The construction of Gas Intelligent Management System

Set up a Control Center with gas intelligent Management System. Transfer the

signals and commands between different units and controlling points via Supervisory

Control And Data Acquisition (SCADA) System; Transfer the signal and commands in

the pressure-adjustment stations and valve of the urban area’s gas system; Transfer the

parameters of the user gap consumption; Load or save the documents such as the

company’s files or original data.

1.3.3 Pipeline system reconstruction

1. Make a 20km-long steel pipe of medium-pressure (0.4MPa) as the main pipe from

Zhuanglin Road to Qinghua Street, which will be made of PE pipe. This pipe will connect

the natural gas distance transferring pipe in Hanhe Bridge. Pressure does not need to be

readjusted in natural gas plants.

3

2. Three pressure adjustment stations will be setup on the new 0.4MPa main pipe,

which locates at Lianmeng Road Cross, Guanghua Road Cross, and Qinghua Road Cross.

The stations will transfer gas to the urban medium-pressure pipe (0.15MP), which will

expand the gas supply area and gas supply ability.

3. Change the pipeline with 9km length, from Liaohe Oil Field Gas Station to the

south bank of Daliaohe River, Tianzhuangtai Town. The part from Liaohe oil field gas

station to Xintun Pressure Adjustment Station Dawa County will be changed to Spiral

submerged arc - welded steel pipe which has been strengthened by 3 layers PE pipe and

the part from Xintun Pressure Adjustment Station Dawa County to the south bank of

Daliaohe River Tianzhuangtai Town will choose PE pipe.

4. Replace the medium or low pressure cast iron pipe and its accessory (such as

valves) with hidden safety trouble. The total length of the pipe is about 15 km.

5. Replace about 30 rotten valves, meanwhile, we will choose valves with distance

controlling in order to cater for the gas intelligent management system.

6. Add up sacrificial anodes cathode protection equipment in the areas of serious

corrosion problem. The total number is about 280 (70 sets).

7. Add up about 40 valves in some key point of the low-pressure pipes and the pipe

entrances or exits in the living areas where accident often happens.

2.2Design Basis

This Environmental Management Plan is designed according to the laws and regulations

of environmental protection in People’s Republic of China; World Bank Safeguard

Operation Policy; related environment protection rules and structured documents in

Yingkou city; the design documents of this project; technical documents on the

construction project’s environmental impact assessment of PRC Environmental

Protection Agency; international environment protocols that signed by China; etc.

3 Pollutant Discharge

3.1 Waste Gas Emission of the Project

No atmospheric pollutant will be produced while the project runs normally. If the

pipe pressure were over the normal, the adjustment stations will activate the safety valve.

Since this program aims to the amendment of medium-low pressure pipe, and automatic

protection unit will be setup, over-pressure problems will seldom appear, so the nature

gas leak will be little.

3

3.2 Waste water

The waste water during the project’s running is mainly the daily domestic waste

water. Since no new workers needed in this project, the water consumption keeps the

same as before.

3.3 Noise source

The noise source of this project is the new gas pressurization machine’s noise (85-

90dB(A)). Besides, if the new pressure adjustment station’s pressure is over the normal

range, the safety valve will be activated, just at the moment the gas released, noise will be

burst out at the maximum of 85 dB(A).

3.4 Solid waste

The solid waste of this project is the 3 new adjustment station’s used filter, which

will be replaced on time. Usually, filter will be changed ever 3 months. The weight of a

filter is about 0.5kg, so the yearly solid waste is about 0.006t/a.

3.5Pullutant reduction by the newer for the replacement of the old

one

The main method of using the new to replace the old in this project is to solve the

over release of smoke and dust from the factory’s boiler and daily waste water. By means

of the update of the boiler’s dust remover and water treatment system, the correct smoke

filter system and waste water treatment system will help the factory reduce pollutant and

reach the limit , so that the amount of pollutant will be reduced. After this method, the

pollutant of Yingkou Coal Gas Company will be as follow table 3-1.

According to the above date, all the areas of Yingkou City’s noise reaches the

standard, the Sound Environment Quality is good.

4.2 Environmental Impact Analysis in Construction Period

4.2.1 Analysis of Ambient Air Impact

The air pollution during this project comes from the following activities: dust

during the pipe channel digging by the bulldozer; dust spread by the basic contraction

of the storage cabinet, vehicles, road digging, and mechanical running; the dust and

splash of the mechanical materials (such as cement, lime, and sands) during the

transportation, and the waste gas from the mechanics, vehicles and generators.

1. Flying Dust Impact Analysis during Construction

Reference by general contraction fields’ data, the daily TSP can be within the

standard in the places, where is 50 m away of the field pipeline

The new storage cabinet will be built in the yard of the gas source plant, and the

nearest residential place in Laobian District is 400m away from the factory. With the

above method, the dust during the cabinet construction will affect the residents little.

2. Exhaust Waste Gas Impact from the Vehicle Analysis during Construction

The amount of waste gas from the vehicle is minor; most of the pipes will be

built near the main traffic line in the urban area, and the gas source plant locates by

the Yingkou-Dalin Road. These roads are quite busy; the additional volume of traffic

flow is not too much. So, the additional air pollution by the vehicles can be ignored.

7

4.2.2 Analysis of the Water Environmental Impact

The waste water during the construction includes the waste water from the

pipeline construction and gas source plant construction.

1. Waste water from the pipeline construction

-waste water for the pipe installation

Most of the pipelines will be installed in the urban area. The possibility to touch

the underground water level is quite low. So the waste water is mainly the cooling

water for the mechanics, and washing water for the transportation, and the waste

water with oil dropped by the mechanics, the total volume of waste water is minor. If

it rains, the water resistant instrument in the construction field can reduce the flow to

take the dust, sands, rubbish, and waste soil away. The waste water fits the standard of

the treatment factory, so it will be sent to the drainage treatment plant for treatment.

So, the minor amount of waste water can be controlled in the limits of the standard by

means of the above methods.

- Waste water while across the pipeline

The main pipe will come across the rivers for 7 times, except the pipe with

bridge installation will be used in the Bohai Street across Qinbai River, the directional

digging methods will be used in the rest places.

During the directional digging methods, a little waste mud and solid waste will

be produced. The main component of the mud is bentonite and a little addition agent,

which are non-poisonous and harmless. But if the mud comes into surface water

directly during the rainy season, it may raise the percent of sands in the nearby rivers,

canals or drainage pipelines; increase the amount of suspended particle in the river

and the turbidity degree. This report requests mud-collecting and disposal pool set up

by the borer, only the supernatant fluid is allowed to be discharge. With the above

methods, the affection to the water quality during the construction can be limited in

the acceptable range and no obvious affection appears in the water environment.

Pipe with bridge installation will be used in the Bohai Street across Qinbai River,

since no ships needed, there will be no affection to the water environment.

2. Waste water in gas source plant during construction

The construction of this plant is a general construction, which waste water is the

8

cooling water for the mechanics, and washing water for the transportation, the

waste water with oil dropped by the mechanics, and domestic waste water

produced by the constructors. This construction area is quite small, waste water

produced by mechanics is not much; most of the waste water is domestic waste

water. The report requests Yingkou Coal Gas Company to install a whole set of

domestic waste water treatment before the cabinet construction, which can

make the domestic waste water fit Grade II of LiaoNing local standard on

discharge of wastewater and exhaust gases (DB12-60-89).

With those methods, the waste water during the construction of the plant can be

controlled in the acceptable range.

4.2.3 Analysis of the Acoustic Environmental Impact

Most of the pipelines located at the main streets or road of Yingkou City, which

will affect the daily life of the citizens. So, nighttime construction is forbidden,

besides, even in the daytime, strict methods will be carry out to reduce the noise

affection to the environment. The project should adopt the method of segmental

construction to reduce the impact the surrounding residential area. the impact is

temporary and acceptable.

The noise in different stage of the construction will be controlled between 85-

100dB (A), the noise source is intermittent during the construction. Since there are not

residential areas or other environmental hot places within 1000 m of the field, and

only daytime construction allowed, there will be no affection to the residential.

4.2.4 Analysis of the Ecological Environmental Impact

This cabinet construction will be built in the existing plant, no new land

occupied.

1. Temporary Land Occupation

Pipelines reconstruction will be done to the original pipe places, no trees will be

felled; new pipes will be done in the pavement’s reserved gas pipe areas of the new

roads; suburbs pipe reconstruction areas are mainly dry lands. Since the construction

will be made from January to April, affection to the plants is little. In the urban area,

9

people and the mechanics dig together, the stage excavation method is adopted in the

cultivatable land and protect the former ecological environment for the landfill with

the bottom soil which is separated from the surface soil when digging. In addition, the

accumulated landslide should be reserve to prevent the ground surface sink and soil

and water loss for the runoff and rainfall. The soil used for the landfill is the deserted

soil and disposal properly in the field. The environmental impact on the ecological

will be reduced with the above methods.

2 River-crossing impact

The river-crossing methods of the project are pipe with bridge installation and

directional digging methods. Since directional digging method will not touch the

water, and pipe with bridge will not use a ship, there will be no affection to the river.

And the affection to the water environment is temporary, so this minor affection will

become less and less, and disappear finally.

4.2.5 Analysis of Solid Environmental Impact

Solid waste during construction includes: waste pipes and valves, domestic waste

produced by the constructors, waste soil during pipe construction, dry-mud during the

digging, and the building waste during the construction of gas source reconstruction.

1. The weight of waste pipes and valves is about 1400t, can be recycled and sold

out, which will not affect the environment.

2. The total amount of domestic waste of the pipe and factory construction is

about 130kg/d, which will be collected by Yingkou Environmental Sanitation

Department, there will be little environmental affection.

3. Most of the pipe working is old pipe update and the digging soil equals to

refilling, the new medium-pressure gas pipe locates at the new road of Zhuanglin

Road and Qinghua Street, the solid waste can be used as the roadbed, the construction

waste can be used to pave the road.

With the above treatments, the solid waste cannot affect the environment

seriously.

4.2.6 Analysis of the Society and Traffic Impact

The range of this project’s pipeline is quite broadly, especially in the main road

10

of the urban area of Yingkou. Since these streets are busy, and many passengers

nearby, the construction field will occupy the non-vehicle roads and pavement, which

will affect the traffic seriously. The noise of it will affect the residential. After the

construction plan has been made, it should be declared to the public in advance, to

minimize the affection of the citizen’s daily life and traffic.

But the pipe construction is step by step, and the affection is temporary and part,

as soon as the construction finishes, the impact will be disappear. By the conversation

with the residence, and get the understanding, the impact to the society and traffic can

be acceptable.

4.3 Analysis of the Environmental Impact in Operation

4.3.1 Analysis of the Ambient Air Impact

This project can not only change the rotten and old gas pipes of Yingkou city,

which will reduce the gas loss, but also will raise the natural gas consumption of the

city, so that change the energy consumption structure, reduce the consumption of coal,

so that the SO2 and dust can be reduced, which will clear the atmosphere of Yingkou

City.

Besides, according the requests of the evaluation, as the building of 50,000 m3

dry-style gas storage cabinet, the 2 old 4 ton steam boils’ dust remover will be

updated. As the engineering analysis, after the update of the dust remover, the smoke

can be limited as lower than 97 mg/m3 which fit the standard. The reduction of smoke

discharge is 12.3t/a, or 80%. It can improve the air condition around the gas source

plant.

4.3.2 Analysis of the waste water impact

As the construction analysis, this project will not increase the waste water

discharge of Yingkou Coal Gas Company, and as the request of this evaluation, the

plant should install a whole set of domestic waste water treatment, which can make

the domestic waste water fit Grade II of LiaoNing local standard on discharge of

11

wastewater and exhaust gases (DB12-60-89). all the pollutants in the waste water will

be lowered. It can improve the water quality of Laobianhe River.

4.3.3 Analysis of Noise Environment Impact

The Noise of the project is the running noise of the new gas compression

machine (85-90dB(A)). The new machine located inside the original machine room,

which can reduce the noise at about 25dB(A), the noise value after the distance decay

to the plant boundary and superimposed the existing boundary noise is as table 4-4.

As table 4-4, the boundary noise of the gas source plant will keep the existed

level and do little impact on the boundary noise and meet the requirement of Standard

for Noise at Boundary of Industrial Enterprises Grade Ⅱ(GB12348-90).

And, the instant noise while the new pressure adjustment station pipe’s pressure

is too high, noise reduction instruments and methods are applied. The new stations

located at the main crossroad with the equipment of the overpressure exhaust pipe

fitting the mufflers meet the requirement of Standard of Environmental Noise of Urban city

Gradeⅳ（GB3096-93）4.3.4 Analysis of Solid Waste Environment Impact

The solid waste of this project is the old filter of the 3 new adjustment stations.

12

The amount is about 0.006t/a. the waste filters are general solid waste, and the amount

is minor, which will be sent to Yingkou Solid Waste Treatment Plant, which will not

affect environment.

the gas source plant and the urban area via underground pipes. The length of the high-

pressure pipe (0.6MPa) is 6 km, middle-pressure pipe is about 51.8km (0.4Mpa:

37.1km, 0.15Mpa: 14.7km). Considering the different danger of the pressures, the

range of the evaluation includes the above middle and high pipeline only.

5.2 Environmental Risk Types

As the techniques of storage and transfer of natural gas have been adopted in this

project, the environmental risk types are are as table 5-2.

5.3 Risk probability and the confirmation of the sources

(1) Storage Unit

The probability of the fire/explosion of the natural gas tank in this project is

4.0×10-7/a, referenced by domestic statistics.

The ordinary banks leak usually occurs at the jointing of the tank and the pipe, or

the valve. Here, we presume that the jointing part of the gas-in pipe/gas-out pipe

break in one of 50,000 m3 tank, and the natural gas leaks, the operators have stopped

the gas leaking within 30 minutes. After calculation, if the gas-in pipe is broken, the

leaking rate of the gas is 0.046kg/s, the amount of leaking gas is 82.8kg; if the gas-out

pipe is broken, the leaking rate is 0.062kg/s, the amount of leaking gas is 111.6kg.

(2) Transportation units

15

After the construction, the length of the high-pressure pipe (0.6MPa) is 6 km,

middle-pressure pipe (0.4Mpa) is 37.1km. We presume that two kinds of pipes are

broken, the leaking part is 60% of the diameter with 20mm perforation. The

calculation result for 30 minutes’ leaking is: for 0.6Mpa pipe, the leaking rate is

2.01kg/s, the amount of leaking gas is 3618kg; for 0.4Mpa pipe, the leaking rate is

1.34kg/s, the amount of leaking gas is 2412kg.

5.4 Consequence Calculation

5.4.1 Consequence calculation for the explosion range after

leaking

1. Diffusion pattern of the natural gas

The calculation of the diffusion pattern of the natural gas should adopt the non-nomal

emission pattern Technical guidelines for environmental impact assessment (HJ/T2.1-

93)

2. The estimation of the range of the flammable explosion

Take longest distance at the lower explosion limit concentration for the natural gas in

the Leeward approaches – 33g/m3, as the longest dangerous radius. In different

meteorological condition, time, and the leeward distance from the incident place. The

result is as table 5-3.

min, the density of the leaking gas cloudy cannot reach the explosion limit if it is

windy or breezy; if the High pressure(0.6MPa ) pipe or Middle pressure(0.4MPa) pipe has

been broken for 30 min, the density of the leaking gas cloudy cannot reach the explosion

limit if it is windy, the leeward explosion distance will be 6m and 5m if it is breezy.

5.4.2 Consequence calculation for the fire explosion after leaking

This part takes TNT equivalent method with over-pressure & stamping criteria

to estimate the impact range of the natural gas cloud. The result is as table 5-4.

and 83m. As the investigation, the closest residential point is 100m away from the

point, so the tank explosion will damage little outside the factory.

When 0.6MPa pipe is broken, then fire causes the explosion, the Fatal Radius, GBH

radius, slight wound radius, and property damage radius are 38m, 56m, 101m, and

116m.

101m.

5.5 Risk Calculation and Assessment

5.5.1The acceptable level of the environmental risk

The environmental incident is quite unstable, so the estimation to the aftermath is

very uncertain.

According to the definition of venture:

During the procedure of the calculation, the following equation is used to

calculate the incidental risk (death/year):

Venture=Half lethal percentage area population * 50% * incident probability * weather

probability

The unit for risk is “death/year”. The level of the common incident can be

divided into max acceptable level and ignorable level. In industry and other activities,

the risk levels are as table 5-5.

Table 5-5 Risk level and the acceptable level

Risk (death/year) Risk level Acceptable level

10-3 Very dangerous, equal to the nature death rate unacceptable

10-4 Medium Must be improved

10-5 As the swimming incident or Gas poisoning

People concern it, and would like to take some preventing methods

10-6 As earthquake or other natural disasters People do not concern on it

10-7～10-8 As the meteorite hurts people No one would like to prevent this kind of incident

Chemical-engineering industry is high-risk. The evaluation takes some

recommendation acceptable level according to different country’s situation, as table 5-

6.

Acceptable Venture(year-1) 8.33×10-5

As table 5-7, the max venture for the project is 3.7×10-6, which is lower than the

acceptable risk 8.33×10-5.

5.6 Risk Control Measure and Emergency Response Plan

5.6.1 Risk Control Measure

This project is going to set up an SCADA management system for the safety

running of the gas pipe and reduce the potential risks. This system will be controlled

by the administration center at the Yingkou Coal Gas Company’s building. Here, the

standard, layout, equipment models, fire control, automatic management, and running

19

management will be analyzed for the risk control.

(1) Design Standard

The standard of the gas pipe and gas source plant are Code for design of urban and

rural gas supply (GB50028-93, version 2002) and Code for fire protection design of the

buildings(GBJ16-87, version 2001). They are the criteria general acceptable in China,

the existing cases have confirmed the security. So the standard of the pipes and

factory is guaranteed.

(2) Layout for the tank and pipes

Dry-type storage tank

A new 50,000 m3 Dry-type storage tank will be set up to the east of the existing

50,000 m3 wet-type storage tank, the safely distance to the around buildings accord

with Code for design of urban and rural gas supply and Code for fire protection design of the

buildings The width and Radius of turn for the road in the raw gas factory cater to the

requests of fire prevention and transportation.

The new 50,000m3 Dry-type storage tank is more than 150m away from the hot

points outside the factory, such as the resident points. According to the estimation, the

tank explosion affects little outside the factory.

Gas Pipeline

The pipeline from Dapingfang Station to Laobian gas source plant is the existing

pipe. This time, only the pipes from Dapingfang Station to Xintun Pressure-

adjustment station and the part which will come across the Daliaohe River will be

replaced. The routine of the pipe is unchanged. The new middle pressure pipe will be

laid along Zhuanglin Road and Qinghua Street; the middle pressure and low pressure

pipe in the urban areas will be replaced without routine change. Because of the need

of gas supply, the working in residential area is unavoidable and the risk will be

prevented during construction and management.

(3) Equipment models

Type of the tanks

20

A new 50,000m3 Dry-type storage tank, and the accessories, such as pressure

adjustment instrument, flow meter, pipes, compressor, and valves. As the reports, all the new

equipments will be in according with Law of the Peoples Republic of China on Bid Invitation

and Bidding: for the high equality and stability.

Height measurement to the 50,000m3 Dry-type storage tank without height alarm

if the height is above the alarm line sound and light alarm will start.

Combustible gas detector will be set up in the factory’s tank valve room, because

the raw gas factory is the explosion prevent Area, Class A.

Emergency amputation valve and safety out-spreading valve will be set up at the

entrance and exit to the tank, when the tank pressure reaches the level, the valve will

be closed automatically, when the pressure is over the safety valve’s point, the safety

valve will be released automatically, so that the tank can run safety.

Types of the pipeline

According to the report, the update part from Dapingfang to Xintun Pressure

Adjustment Station will take Spiral Submerged Arc Welded Steel, the other new or

update part will use PE pipes. For the steel part, 3 layerss PE corruption-preventing

method will be taken, and 100% Inspection will be made. Valves will be set up every

2km.At all the crossing important rivers parts, and middle pressure start points, valves

will be set up in valve wells or directly. The materials for the pipes and valves will be

in accordance with the standard. All the pipes are underground, so that the damage

from traffic incidents can be avoided.

The possible reasons of the other domestic gas pipe incident are pipe’s quality, or

the not-enough protection to the nearby gas pipe during the other underground

construction. So, after the installation, marked alarm signs with the gas company’s

and police telephone must be set along the pipeline.

Besides, leakage inspection and emergent repairing instruments must be set up,

so that the leaking points can be found quickly and exactly, and emergency repairing

will be possible.

(4) fire control,

21

As Code for fire protection design of the buildings, after the new 50,000 m3 Dry-type

storage tank’s construction, the storage ability for the factory will be 1,200,000 m3,

the fire control water is 30L/s(108m3/h). As 3 hours calculation, the total fire control

water is 324m3.

There is a 600 m3 fire hydrant reservoir to the south of the new tank, which fits

the request of the fire controlling. Fire controlling pipes will be set up as a circle, the

diameter is DN150. 3 and fire hydrants will be set up outside the reservior.

The damage of fire in the raw gas factory is quite dangerous, and the fire caused

by gas is difficult to be controlled, so the most effective way for this kind of fire is to

cut the gas. To ensure the safe running of the factory, combustible gas inspectors, fire

controlling system, and mobile fire extinguishers are quite important for the fire

happen. The other fire extinguishment can rely on the local fire station.

(5) Automatic management

Automatic management is quite an important part for the city gas supply. To

ensure the stable running of the natural gas network and reduce the potential risks, a

SCADA management system will be set up for this project. This system is a 3-level

distributed control system, a controlling center will be set up in the Gas company’s

office building, which is a system administrator in charge of data monitoring; the

SCS, High-middle-low pressure adjustment stations and middle-low pressure

adjustment stations are the 2nd level; RTU System in the network, data collection and

system control are the 3rd level. The 3 layers system combined with cable or wireless

network to work as a SCADA System. 3 SCS will be set up independently along the

high pressure pipes: High-middle pressure adjustment station at Lianmeng Road,

Huanghua Road, and Qinghua Road. 30 valves updated in the middle pressure

network will be set up as distance RTU terminations. These automatic management

systems are not only to ensure the gas supply, but to keep the pipes and factory safe.

(6) Operation management

The operation management includes:

22

Safe and fire protection committee: Voluntary fire brigade, gear groups, Rescue crew, and

Public security Crew. Anti-fire drills will be practiced on time, anti fire plans will be constituted

with the guidance of local fire stations.

Rules, such as safety operation regulation, Fire protection responsibility system, post

responsibility system, daily and preventive maintenance system, and the regular System of

examining and assessment for the staff

Staff safety and technique education, all the worker at the production line will pass the exams

first

Technical document management, regular and daily check/fix

Direct line telephones set in important section for the emergency help

Fire alarm, notice the staff and nearby units as soon as the incident happens

Post set at the entrance to the working area. Post with “Smoking and lighting fires strictly

prohibited.” set on the wall to the working areas and in the living area/

Strictly obey the national and gas industry’s rules and regulation for safety

Regular inspect, management, and maintenance to the fire-fighting equipments

Put out the initial fire in time: operate the firefighting pump, water system, and

use powder fire extinguishers to put out the fire promptly

Cut off the electricity as soon as the leaking gas fire in the station’s workshops.

Close all the related equipment, pipes (close the emergency valves at the entrance and

exit), and take effect methods, report it to the local fire station and controlling center.

The above methods are the existing management methods, system, and

organizations in Yingkou Coal Gas Company.

5.6.2 Emergency Response plan

Natural gas is a kind of inflammable and explosive substances. Although strict

risk preventing methods are taken for the storage and transferring, leaking incidents

are still possible. The leaking gas explosion will be possible with the open fire, which

23

will endanger the nearby people and buildings. So as Technical Guidelines for

Environmental Risk Assessment, Accident emergency predetermined plan must be

made for this program.

The Emergency response plan of accidental risk in this project is as table 5-8.
