Planning by EIA team during the Scoping visit

➢First Phase of EIA: To carry out the scoping so

as to brief the local about the project

➢A 15 days Public Notice Published and Provided

to concern people and the public places like

schools, health posts, municipality offices, youth

clubs, etc.

Public Notification

➢Records of

Public Deed

of Enquiry:

Collected

VISION LUMBINI

Public Consultations➢Public Consultations

Meetings - done

➢ Information on Present

Environmental and

Sociological Condition

were gathered

VISION LUMBINI

Public views were gathered as

➢ People were excited about the project.

➢ People have positive thinking about

the project - from NTNC staff to

municipality personnel; from teachers

to local resident, from health personal

to local politician.

➢ People would like to support the

project.

➢ Project has less issues and less

environmental/social impacts – “so

the project is a go ahead”.
