He also sought environmental clearances for the Palamuru-Rangareddy Lift Irrigation Scheme and other irrigation projects. Accompanied by Irrigation Minister N Uttam Kumar Reddy, Revanth Reddy called on Union Jal Shakti Minister CR Patil in New Delhi on Wednesday. Separately, Revanth Reddy and Uttam Kumar Reddy urged Union Environment Minister Bhupender Yadav to expedite environmental clearances for the Palamuru-Rangareddy, Gouravelli, Sita Rama Sagar and Dindi projects. They said the State had already spent Rs 36,437 crore on Palamuru-Rangareddy, Rs 3,187 crore on Dindi, Rs 1,835 crore on Sita Rama Sagar and Rs 1,350 crore on Gouravelli. They said delays in clearances had stalled works and increased project costs, and sought immediate approvals in view of a recent Supreme Court verdict.
