I GENERAL INTRODUCTION

According to electric network investigation figures at 8 districts of Ha Noi city found that some of Medium voltage lines and low voltage networks not ensure reliability and safety

in supply electricity needed to be upgraded voltage and fall cable for ensure reliability Although Some of Low voltage networks are still good but go in the garden of private house, too close the private house This will make the operation meet with difficulty in the future Therefore, they have to be adjusted to reduce compensation cost Many actual substations is

construction cause soil erosion?

foundation is not long (maximum about one week) and avoiding to construct in raining seasons and constructing definitively each item, so the erosion is negligible.

Will Project need to open new access

roads?

X Using the current road system to

construct because the route and substation areas are along traffic road

Will Project cause fragmentation of

habitat of flora and fauna?

X

Will Project cause impact on air

quality?

exhaust fumes of traffic means during transportation will be limited by covering, avoid scattering.

Will Project cause accident risks for

workers and community during

construction phase?

- Transporting bulky materials and equipment (pole, transformer), it is

Screening Question Yes No Remarks

easy to cause accident for community

- The workers construct in sloping area are able to be in risk as falling if they are not equipped safety knowledge and labor protection

The mitigation measures for these risks

of workers and community when constructing are presented in part 6

Will Project generate hazardous wastes

including PCBs from the replacement

of transformers?

X In this project, there is replacement of

old suspending transformers These transformers are verified not to include PCBs, so it will not affect environment.

Will Project cause risk to safety and

human health (electric and magnetic

fields, electric shock etc.)?

X - The transmission lines shall be designed and constructed in accordance with applicable standards

of power industry (in accordance with Vietnam applicable technical regulations, electromagnetic field (EMF) < 5 kV/m), wherein impacts from EMF and safety standards and operation safety have to be taken into due account

- Prior to operation, all safety indicators shall be tested and accepted

by the project owner, contractor and operation entity therefore workers shall not be suffering from such EMF impacts.

- In the phase of commissioning, the safety in power use of households of ethinic minorities who use electricity for the first time also needs to be paid attention to minimize the risk of electric shock However, this impact is very little and avoidable if the people are trained well in safe power use

- The mitigation measures in Section VI will also be implemented to minimise safety risks
