The Centre is chalking out guidelines for the Petroleum and Petrochemical Investment Region projects that have got in-principle government approval and are expected to attract huge investments, Minister of State for Industry Ashwani Kumar said in Jalandhar on Monday.

The Centre is actively involved in pushing through the PPCIR projects which would be spread over an area of 200-300 sq km each, Kumar told reporters.

"The PPCIR has received an in-principle approval from the Cabinet. Once the policy is notified, it will lead to mega-investments through the PPP (public-private-partnership) mode in the coastal states," Kumar said, adding that inter-ministerial consultations were on at present and rules are to be framed.

"PPCIR will be replicated in a total of five coastal states, including Orissa, Gujarat, Andhra Pradesh and West Bengal. Indian Oil [Get Quote] will be the anchor tenant in Paradip (Orissa), ONGC [Get Quote] in Vizag (Andhra Pradesh) and Reliance Industries [Get Quote] in Jamnagar (Gujarat)," Kumar said.

Regarding Delhi-Mumbai Industrial Corridor, the minister said the government is committed to complete this project, which is expected to  cost about Rs 4,00,000 crore (Rs 4,000 billion).
