The State Environmental Impact Assessment Authority has refused to clear 28 real estate projects, and cancelled its clearance for projects proposed by Mantri Techzone and Coremind Software.
The cancellation orders went out on February 23.
Mantri had got a clearance certificate on February 17, 2012, and Coremind on September 30, 2013.
Mantri had sought clearance for the mixed use development for residential, retail, hotel and office space in Agara and Jakkasandra, Bengaluru South taluk. Coremind wanted to build Sattva Domain, a software technology park, in Agara.
The impact assessment authority has also cancelled clearances granted to 28 other builders, and turned down an application pending since 2014.
The orders are based on the May 2016 National Green Tribunal ruling that a buffer zone of 75 metres be maintained around lakes and wetlands.
The firms and individuals did not comply with the stipulations for revised environmental clearance, according to Ramachandra, member-secretary of the state impact assessment authority.
Ramachandra said the areas proposed for development by Mantri and Coremind fall in the wetland zone of Bellandur lake.
After a fire broke out in the lake on February 16 this year, the NGT took up a suo motu case against the state government, custodians of the lake, and the Karnataka State Pollution Control Board.
The tribunal had directed them to file affidavits within two weeks.
The state government is not happy with the tribunal’s order and will move the Supreme Court to seek a revision of its buffer zone guidelines, sources said.
