Clean Water Act Section 401: Balancing States’ Rights and the Nation’s Need for Energy Infrastructure
Over the past several decades, significant tension has developed between the federal role in overseeing and authorizing certain types of energy infrastructure projects and states’ roles in regulating water quality under the cooperative federalism structure of the Clean Water Act (CWA or the Act). This tension has played itself out in various contexts, but the…

Act or Waive: DC Circuit Construes CWA § 401’s One-Year Deadline for State Action Applications
“According to FERC, it is now commonplace for states to use Section 401 to hold federal licensing hostage.”
These are the words the DC Circuit used in Hoopa Valley Tribe v. Federal Energy Regulatory Commission, No. 14-1271, p. 10 (D.C. Cir., Jan. 25, 2019), to describe the state of play on § 401 certifications affecting hydroelectric facility licensing or re-licensing applications. CWA § 401(a)(1) requires, as a prerequisite for federal permits for activities that may result in a discharge into the navigable waters, that affected states certify that any such discharge will comply with applicable, enumerated provisions of the Clean Water Act. But, if a state fails or refuses to act on a request for certification within “a reasonable period of time (which shall not exceed one year) after receipt of such request,” the statute deems the certification requirements waived.

UPDATE: During Oral Argument, DC Circuit Suggests Waiver Period for State Water Quality Certification May Be Less Than One Year
On Friday, a court ruling provided some clarity regarding the Clean Water Act (CWA) § 401 water quality certification process. As forecasted in our November 1, 2018 blog post (below), the US Court of Appeals for the DC Circuit has ruled that a state waives its CWA § 401 authority when, pursuant to a written agreement, an applicant repeatedly withdraws and resubmits its request for water quality certification in order to restart the one-year waiver clock. Hoopa Valley Tribe v. FERC, No. 14-1271 (D.C. Cir. Jan. 25, 2019). According to the Court’s opinion, this sort of arrangement serves to circumvent the Federal Energy Regulatory Commission’s (FERC) “congressionally granted authority over the licensing, conditioning, and developing of [the] project,” and “if allowed, the withdrawal-and-resubmission scheme could be used to indefinitely delay federal licensing proceedings and undermine FERC’s jurisdiction to regulate such matters.”…

EPA and Corps Release Long-Awaited Proposal to Redefine WOTUS
Last week, EPA and the Corps issued a long-awaited proposal to redefine the “waters of the US” (WOTUS) subject to federal regulation and permitting requirements under the Clean Water Act. The reach of the CWA is notoriously unclear, but knowing which areas on your property are jurisdictional and will require permits is critical to project planning and timelines. If finalized, the proposed rule would replace the Obama administration’s contentious 2015 WOTUS Rule and eliminate the regulatory patchwork that currently exists as the 2015 WOTUS Rule is being implemented in only certain parts of the country.

During Oral Argument, D.C. Circuit Suggests Waiver Period for State Water Quality Certification May Be Less Than One Year
In recent litigation involving the development of interstate natural gas pipelines, one of the key issues has been whether the state has waived its authority under Clean Water Act section 401 by exceeding the one-year time period. In a separate case involving a series of hydroelectric facilities, the waiver period was again directly at issue. On October 1, at oral argument before the D.C. Circuit, the parties addressed whether California and Oregon had waived their water quality certification authority by having the applicant withdraw and resubmit its request for certification over a number of years. Notably, the judges seemed to agree that FERC could make a waiver determination before the end of the one-year time limit and that withdrawing and resubmitting an application may not always restart the clock.

Fifth Circuit Vacates Preliminary Injunction on Appeal, Allowing Bayou Bridge Pipeline to Proceed
As we highlighted in our March 2, 2018, post, the US District Court for the Middle District of Louisiana ordered the $750 million Bayou Bridge pipeline to halt construction within the Atchafalaya Basin when it concluded that the US Army Corps of Engineers’ environmental analysis likely violated the National Environmental Policy Act (NEPA) and the Clean Water Act (CWA) due to the following deficiencies:
- The Corps did not provide sufficient explanation for how the proposed off-site mitigation would compensate for the loss of wetlands impacted by construction; and
- The Corps failed to sufficiently consider and address historical impacts to wetlands from past pipeline projects in the cumulative effects analysis.
Fourth Circuit Extends CWA Liability to Cover a Wholly Past Pipeline Spill
In a decision issued on April 12, 2018, a Fourth Circuit panel held (2-1) that (1) even though a pipeline leak has been repaired and remediation is ongoing under the supervision of the state environmental agency, environmental groups have standing to sue the pipeline owner, and (2) plaintiffs’ allegation that groundwater continues to carry discharged pollutants to jurisdictional waters through a “direct hydrological connection” supports liability under the Clean Water Act.
