"It may be delayed for sometime but we are confident to complete the project within 36 months", Mr BVN Rao of GMR Group, which is part of the consortium, told the media here on Wednesday.
The project is expected to be completed by 2006-07. Mr Rao said that the newly released government order has compelled the project to obtain environmental clearances from the Pollution Control Board (PCB) before proceeding further. "We are working with NEERI and other environment agencies to find out proper solutions", Mr Rao said.
Mr Rao feared that if clearances take a long time, the cost of the project may escalate. The estimated cost of project in the first phase will be Rs 1,200 crore.
Originally, the detailed project report (DPR) was prepared by the Tata Economic Consultancy Services (TECS), which had not mentioned the requirement of obtaining the environment clearances for the project.
"However, we understand that the environment clearances are a must due to the new GO and we want to abide by the norm", he added.
As per the GO, the polluting plant or activity is not allowed within the radius of 10 km from the water bodies. In this case Himayatsagar, one of the lakes supplying drinking water to city, is in the vicinity of the airport zone.
