oustees, land oustees and landless laborers (a brief outline to be given)

There is no habitation on the proposed modernization project activity area. So R & R policy

is not applicable to this project.

There shall not be displacement of any population in project area. Any major activity that

may lead to resettlement of the people is considered as permanent impact. Hence, there is no

permanent impact on this account. The increasing industrial activity will boost the

commercial and economical status of the locality up to some extent.
