The state coastal body has set the ball rolling to appraise buildings in Navi Mumbai that have been built without the requisite coastal clearance.
The Maharashtra Coastal Zone Management Authority (MCZMA) on Tuesday decided that it would seek directions from the Centre on how to proceed against these violations.
HT had reported in June that around 500 buildings in the city and Navi Mumbai did not have the CRZ nod.
With union environment minister Jayanthi Natarajan refusing to regularise the buildings, they could face action under the Environment Protection Act (EPA), 1986.
The Navi Mumbai municipal corporation has been asked to submit details on every such building, following which action will be planned.
"Buildings built before 2002 won't be liable as the MCZMA was set up in that year. Also, we will check if the fault lay with the local planning body or the developers," said an official.
The ministry of environment and forests had issued two orders - in December 2012 and June 2013 - for appraising projects that were constructed without the requisite green clearances.
The December order made it mandatory for authorities to prosecute the developer under section 15 of EPA that lays down penalty of up to Rs1 lakh or imprisonment of up to 5 years or both.
The June order says that stop work notice under Section 5 of the EPA should be applied, , under which power and water supply can be cancelled.
