"A Pakistani delegation is planning to visit Iran for which approval of the competent authority has been sought," said an official who declined to be named, nation.com.pk reported.
The gas pipeline project had come under discussion during a visit by the Iranian president to Pakistan last year. Both sides had agreed to discuss the project in the wake of the lifting of international sanctions against Iran.
"It was decided to resolve all outstanding issues, including amendment in the gas sales and purchase agreement to incorporate workable implementation schedule."
Pakistan said it was ready to complete the gas pipeline within 30 months in its territory once the sanctions on Iran were lifted.
The Pakistani government says that it had allocated Rs25 billion ($238.5 million) in the current fiscal year for the development of gas infrastructure across the country, including the gas project.
Islamabad had also requested Iran for amendment in the gas sales and purchase agreement (GSPA) to complete the gas pipeline in an extended period.
Sharing details of the project, the official said an inter-governmental framework declaration was signed between the two countries on May 24, 2009, while GSPA was reached on June 2009.
Subsequently, Pakistan issued sovereign guarantee on May 28, 2010. Project consultant was appointed on April 11, 2011, while the design, feasibility, route survey and other formalities of the project were completed on September 8, 2012.
The 56-inch diameter pipeline will start from South Pars Gas Field in Iran and end at Nawabshah of Pakistan covering a distance of around 1,931 kilometers with 1,150km in Iran and 781km in Pakistan.
The implementation is to be done on the basis of a segmented approach whereby each country will be responsible for construction of pipeline in the respective territory.
Around 750 mcfd gas flow in the pipeline is projected to help generate around 4,000 MW of electricity, along with creating job opportunities for people of Baluchistan and Sindh.
