The Argentine state oil firm is being sued by a former subsidiary over claims it dismantled the company, which also holds it liable over an environmental damages case issued long before YPF bought the company.
The company paid US$26mn for the distribution subsidiary Cepisa.
A 10-day nationwide strike in May caused disruption to essential services and reduced highway traffic.
Legal uncertainty also damages the participation of other stakeholders in the infrastructure sector, such as insurers.
The mayor ruled out the possibility of taking legal action if the environmental evaluation service approves the controversial project.
