"We are now working on obtaining the permit, and we expect that this authorization will be received after our talks by end of October," Novak told Russia's Rossiya 24 broadcaster.
The Opal pipeline connects the Nord Stream pipeline with Europe’s gas transportation network. It runs Russian natural gas across Germany to the Czech Republic.
Gazprom previously asked the European Commission to exclude Opal from the Third Energy Package rules, fearing that Russian gas deliveries to Europe via Ukraine may be interrupted. European restrictions permit Russia's Gazprom energy company only 50-55 percent of the pipeline for Russian natural gas to be delivered across Germany to the Czech Republic.
The restrictions are outlined in the European Union’s Third Energy Package which reserves the other half for independent gas suppliers.
