The state government has a lot of reworking to do if it wants the Navi Mumbai airport plan to see the light of the day.
The proposal has been going back and forth to the Union Environment Ministry, which is yet to give a green signal to the project citing environmental concerns.
The central Expert Appraisal Committee, which has been set up to give environmental clearances for infrastructure projects, in its meeting on September 22 had rapped the City and Industrial Development Corporation (Cidco) saying there is incorrect data and analysis in the air and water quality monitoring data in the report presented.
The committee has also asked Cidco to rework the entire study report the noise pollution measured and figures projected by them.
In September, Hindustan Times had reported that the committee had asked Cidco to reduce the distance between runways and save the diversion of Gadhi river that would have had an impact on nearby Panvel city.
It had also asked for shifting the non-aeronautical component southwards, and moving the 222-hectare Special Economic Zones earmarked in the south of the site to another location.
“We are working on all the issues pointed out by the committee and have conveyed our cooperation for the new airport to get clearance,” said Maharashtra Chief Secretary JP Dange, who has been asked to look into the project.
According to the minutes of the meeting, the committee has suggested that the agency address issues of impact of the peak level of noise created during take-off and landing of aircraft in the vicinity and clearly mention how it will be mitigated.
It also pointed out calculation errors with regards to quality assurance of water and air monitoring data.
The parameters selected for calculating water quality do not include toxic metals, which is mandatory, the committee said. The committee also pointed out several discrepancies in the results for the groundwater monitoring stations and water quality analysis of Gadhi river.
