Landowners: Possible Eminent Domain Risk
If you are a landowner near the project in Acadia Parish, Louisiana, Egan Hub may contact you to negotiate an easement but you are not required to agree. If the Commission approves the project, the Natural Gas Act conveys the right of eminent domain to the company, and if you and the company do not reach an agreement the company could initiate condemnation proceedings in court where a judge determines compensation under state law.
Local Groundwater Users May Be Affected
You live near Acadia Parish, Louisiana, the Commission staff identified that groundwater users in the project vicinity could be affected by groundwater extraction needed for leaching the new storage caverns. The scoping notice asks for public comments on impacts to groundwater so the Commission can evaluate and propose ways to avoid or lessen those impacts.
Risk of Surficial Subsidence Near Project
You live near the proposed Egan Cavern Expansion in Acadia Parish, Louisiana: FERC staff identified surficial subsidence due to groundwater and hydrocarbon withdrawal as an issue to study. The scoping process will evaluate whether subsidence could affect land, structures, or other resources and consider alternatives or mitigation.
Construction and Permanent Land Impacts
You live near the Egan facility in Acadia Parish, Louisiana: construction would require 65.4 acres of workspace within the existing 192-acre facility and operation would create 11.4 acres of new permanent impacts on site. Construction of the separate saltwater disposal (SWD) well would require 5.4 acres and create 1.2 acres of new permanent impacts at that site.
