The Improving Interagency Coordination for Pipeline Reviews Act is designed to streamline the review process for natural gas pipeline projects by enhancing coordination among federal and state agencies. The legislation aims to ensure that these agencies work together efficiently and effectively, thereby expediting the approval process for infrastructure projects governed by the Natural Gas Act. A central provision of the Act designates the Federal Energy Regulatory Commission (FERC) as the lead agency for environmental reviews related to natural gas pipeline authorizations.
