    General Introduction

    VAL Alumina Refinery: 1 MMTPA

    Expansion to 6 MMTPA

    Expand the capacity of aluminium smelter by 13.5 LTPA with

    Captive Power Plant of 5 x 135 MW (675 MW) capacity at

    Jharsuguda, Orissa.

    After expansion, the total capacity of smelter will be 16 LTPA and

    1350 MW CPP.

    Estimated cost, including environmental management of Rs. 593

    crores = Rs.6,500 crores

    Justification of the project

    More than 50 % of Indiasbauxite deposits Orissa (2

    BT)

    VAL to use Lanjigarh deposit

    of 75 MT (3.7 Km from

    plant)

    Agreement with Orissa

    Mining Corp. (OMC) for +

    150 MT

    Environmental Clearance isin advanced stage with

    MoEF

    VAL to be made world class

    refinery with best practices

    Category A project Sub-rule(3) of rule 5 of the

    Environmental(Protection)

    No forest land will be

    utilized for the project.

    The additional land will

    be acquired through

    IDCO. The project site is

    mostly barren land.

    One third the area

    would be covered
