From RT:
“Gazprom is working to depressurize Line B of the Nord Stream 2 pipeline. To do this, the company is pumping the natural gas out of the pipe. This will make it possible to safely inspect the integrity of string B and reduce potential environmental risks from possible gas leaks. If the decision to start gas deliveries via Nord Stream 2 string B is made, natural gas will be pumped into the pipeline after the system integrity is checked and confirmation by supervisory authorities is granted,” the statement says.
I bet theres someone getting chewed out for this.
