Mountain Valley Pipeline, LLC v. Sierra Club, No. 20-1971 (4th Cir. 2021)Annotate this Case
The Fourth Circuit granted MVP's petition for review challenging the Department's denial of MVP's Clean Water Act certification. MVP seeks to build a natural gas pipeline running through North Carolina and its rivers, streams, and wetlands.
The court held that the Department's denial is consistent with the State’s regulations and the Clean Water Act. The court explained that it need not decide which version of the certification regulation to consider because, under the current version of the regulation, the Department's minimization reasoning is consistent with its water quality standards: namely, its riparian buffer rules. Furthermore, the Department properly denied certification, as it found that the temporal adjustment constituted a practical alternative that would better minimize harm to the State's waters. However, the court held that the Department did not adequately explain its decision in light of the administrative record. While the Department's decision adequately explained its concerns with the Mainline Project and the adverse effects of the Southgate Project, the court concluded that it failed to address the hearing officer's minimization findings and explain why it chose to deny certification rather than granting it conditionally. Accordingly, the court vacated the denial and remanded for additional agency explanation. The court remanded for further proceedings.
