MUMBAI: The Maharashtra government-appointed committee to study alternatives to the Metro’s Aarey car shed submitted a draft report to chief secretary Ajoy Mehta on Tuesday. A senior bureaucrat told TOI that the report was “inconclusive”, though it mentioned a “massive cost escalation” as a consequence of shifting the depot.“The government is likely to grant a two-week extension to the panel [led by additional chief secretary (finance) Manoj Saunik] for submitting the final report. After that, CM Uddhav Thackeray will take a call on the Metro 3 depot’s location,” the bureaucrat said.Environment and tourism minister Aaditya Thackeray said the panel’s recommendations “are not binding”. “A final decision will be taken only after studying the report, which has not yet been fully submitted,” he said.The panel studied two more locations, said the bureaucrat TOI spoke to. “It felt that if the depot is shifted from its present location, Aarey, it will result in a massive cost escalation, not to mention a time overrun,” he said.
