"We have proposed the project at 250 sq km on Cuddalore and Nagapattinam, with Cuddalore as the nucleus," S Ramasundaram, chairman and managing director, Tamil Nadu Industrial Development Corporation (TIDCO) said.
"The PCPIR, which would have units and facilities related to petroleum and petrochemicals, is not like a Special Economic Zone (SEZ). It does not enjoy any special duty concessions and would be declared as a preferred industrial area," he said.
Andhra Pradesh had recently obtained clearance for a similar project in the state.
The proposed PCPIR is expected to generate one lakh employment opportunities. He said the proposal was likely to be taken up for scrutiny this month by the Union Petroleum Ministry.
