THE SECOND SEMI‐ANNUAL ENVIRONMENTAL MONITORING REPORT

(FROM JANUARY TO JUNE 2013)

1. Introduction

The railway from Yen Vien station (Hanoi) to Lao Cai province ‐ the border with China

and one branch from Pho Lu to Xuan Giao is an important transportation system for

mountainous northwest. The current railway contains sharp curves and weak bridges

which causes train speed reduction. Besides, the track is lack of maintenance for a long

time; many bridges should be upgraded and replaced as soon as possible.

Asian Development Bank (ADB), Agency Françoise de Development (AFD) and

Direction Generable du Tresor et de la Politique Economique (DGPTE) have assessed

and agreed to provide a loan for upgrading railway Yen Vien ‐ Lao Cai project.

The project objective is upgrading Yen Vien ‐ Lao Cai railway (estimation of 285km

length) in order to improve the transportation capacity and commercial development

in the northern mountainous area. The Project will increase trading profits between

Vietnam and China, especially within the Kunming area.

Beside the positive impacts the project also has negative impacts on the local

environment. Therefore the project environmental management plan is implemented

during the project, in order to:

- Apply appropriate measurement to minimize the negative impacts on environment

complying with the current Vietnam environmental regulations and laws and

environmental policies of international organizations, if necessary;

- Use an appropriate organizational structure in environmental protection throughout

construction period of the Project to ensure that the mitigation measures proposed in

the Environmental Impact Assessment Report or IEE and EMP are effectively

implemented;

- Planning to deal with the environmental emergencies and accidents that may occur

during the implementation of the Project;

- The Environmental Management Plan shall be implemented by the Contractors during

the work execution and shall be monitored by the Engineer and the Employer on daily

basis.

2. Incorporation of Environmental Requirements into Project Contractual

Arrangements

`



4

To implement the requirements of the project environmental plan effectively, the

tasks/work are arranged as follows:

- Supervision consultant and Independent contractors environmental monitoring:

i) Carry out baseline environmental monitoring and monitor implementation

of the environmental management plans, including any required sampling

and testing to ascertain baseline and in‐construction noise pollution, air

quality, water quality and solid waste disposal requirements.

ii) Report on any difficulties in the monthly and quarterly progress reports and

recommend the implementation of amelioration measures to be taken to

reduce adverse impacts.

iii) To monitor the baseline environment in the project area the construction

phase.

iv) Reporting the status of the environment and propose the application of

measures to minimize the impact on the surrounding environment.

- Contractors (including subcontractors):

i) Implementation of environmental monitoring of air, water, solid waste at

the construction site and areas affected:

a. Monitoring number, status, changes in negative impacts’ origin arising

from construction site to environment quality;

b. Subscribe flow/ volume/ frequency and period measurement, sampling

and analysis of pollution parameters, characteristic of the waste arising

from the facility operation (waste water, waste gas and solid waste,

hazardous waste, noise, vibration, and other criteria);

c. Periodic measurement, sampling and analysis of the parameters related

to the negative environmental impacts origin in the area (surface water,

groundwater, air, soil);

d. Monitoring of changes and measure the current status factors (if

relevant): erosion, sliding, falling, landslides, land subsidence; river

bank erosion, stream, lake; sedimentation of rivers, streams, reservoir;

changing the water surface and underground water; and other impacts.

ii) To monitor and inspect food, and sanitary conditions at construction site.

iii) Report on construction activities at the site and the current state of the

environment during the construction process, the comments complained

of the surrounding community.

`

iv) Adjust the construction activities; apply measures to minimize

environmental impact.

3. Scope and Reporting period

Environmental monitoring report for the first six months of year (from January to June

2013) will aggregate the environmental performance of Yen Vien ‐ Lao Cai railway

upgrading projects in general and environmental control activities, the environmental

mitigation measures are applied to the construction bid package. The report reviews

the compliance of environmental activities with EMP and proposes activities in the

future environment in order to control and minimize negative environmental impacts.

4. Methodology

The project environmental monitoring report bases on the following methods:

- Methods listing: Specify the full impacts caused by the project's activities.

- Methods of synthesis compare: Synthesis of data collected, comparing with

environmental standards then assess the current state of environmental quality in

the studied area, forecast evaluate and propose solutions to minimize the project

works environmental impact.

- Field survey method: field sampling, laboratory analysis of samples in accordance

with the provisions of VN standards to determine the environmental quality

parameters (including: air quality survey, noise, water quality, wastewater

composition, ecosystem project area). Field visits and compare with the

regulations on sanitary conditions, labor safety, fire protection, electrical safety...

- Method of assessment: the calculation load of pollutants from the production

activities of the project.

Through inspection, field supervisor can evaluate:

- The sanitation facilities are available or inappropriate;

- Have water supply for drinking and washing.

- In some sub‐contractors the first aid provisions not enough, safety equipment in the

construction site as provisions.

- For spoils disposal site: some only have obtain agreements with land owners

- Well done the specified on safety in the construction process to ensure the safety of

the community

- The required mitigation measures are sufficient or still appropriate considering current

site conditions and on‐going site works.

- A some difficulties in the implementation of measures to minimize the impact on the

environment: (1) due to the construction of most of the small streams, slope, high

water flow rate should be made to reduce the suspended solids difficulty; (2) the

gathering of excess solid waste for disposal is limited by the volume is not large,

transport distances are too far away and difficult; (3) the time to mobilize engineering

supervision is not sufficient to ensure task requirements.

6.2. Environmental Effects Monitoring

6.2.1. Monitoring baseline environmental

Environment monitoring construction stage wasn’t carry out in this 6 months (January

to June 2013).
