Sierra Club v. National Park Service, No. 18-1082 (4th Cir. 2018)Annotate this Case
The Fourth Circuit held that agency decisions that provided necessary approvals for the Atlantic Coast Pipeline (ACP) were arbitrary and capricious. In Case No. 18-1083, petitioners challenged the Incidental Take Statement (ITS) authorizing the pipeline to take five species listed as threatened or endangered. The court held that, although FWS was not required to set a numeric limit, it can only use a habitat surrogate if it demonstrates a causal link between the species and the delineated habitat, shows that setting a numerical limit was not practical, and set a clear standard for determining when incidental take is exceeded. In this case, FWS failed some or all of these requirements for all five challenged species, and thus the agency's take limits were not enforceable.
In Case No. 18-1082, petitioners argued that NPS lacked the authority to grant a right-of-way to a gas pipeline and that doing so violated the statutory mandate that agency decisions not be inconsistent with the Parkway's conservation purpose. The court assumed that NPS had the requisite statutory authority but held that NPS did not explain how the pipeline crossing was not inconsistent with the purposes of the Parkway and the overall National Park System.
