There is fresh trouble for Vedanta Resources. The environment ministry has ordered a probe into allegations of encroachment of forest land by its Balco plant in Chhattisgarh. Vedanta has 51% stake in the plant, through its subsidiary Sterlite Industries. The probe was ordered in response to allegations that the Balco plant has occupied forest land. Former Chhattisgarh chief minister Ajit Jogi had flagged the attention of the Union environment ministry to the violations. Balco was a PSU which was sold to Sterlite Industries during the NDA regime.
