Will groundwater be affected by construction?

The Project is not expected to negatively impact water quality or supply during or after construction. This point was confirmed in FERC’s Draft Environmental Impact Statement, issued in May 2016: “…the project is not likely to significantly affect groundwater resources because the majority of construction would involve shallow, temporary, and localized excavation.”

Williams proposes to implement construction practices to minimize potential impacts on groundwater during construction, which will be detailed in the project Environmental Construction Plan. Additionally, Best Management Practices for erosion and sediment control, as well as equipment refueling and management of incidental use of hazardous materials, will be implemented during construction activities to prevent impacts on water quality.
