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.

Do you avoid all cemeteries and burial grounds?

Williams does not intend to site through or to disturb any cemeteries during the survey process or during pipeline construction. If we are made aware of a cemetery, we will revise the route accordingly to avoid all cemeteries, including (but not only) Euro-American and Native American.  To our knowledge, no background data shows that the current primary route passes through or near any Native American or Euro-American cemeteries, and no information was provided during the open houses to indicate that the route would affect any cemeteries.  Williams and the FERC will consult with Native American Tribes in or near the project to determine locations of cultural significance, including the location of cemeteries and burial grounds. There is a possibility that human remains could be discovered during the archaeology studies, as shallow shovel testing is performed.  However, if human remains are discovered, surveys will stop, the site will be placed back to pre-disturbance condition, and the route will be revised accordingly.

What methodology is used for cultural resource surveys?

In conducting the cultural resources survey for the Atlantic Sunrise Project, Williams is following the Pennsylvania Historical and Museum Commission’s (PHMC) Guidelines for Archaeological Investigations in Pennsylvania (Revised November 2008) and Guidelines for Architectural Investigations in Pennsylvania(2014).  The specific methodology for the cultural resources survey was discussed at an initial consultation meeting with PHMC staff on 1 May 2014.  The PHMC issued concurrence with Transco’s proposed methodology, and the Unanticipated Discovery Plan, in letter correspondence dated 11 June 2014 and email correspondence dated 26 June 2014.

Does the pipeline jeopardize the Tucquan Glen nature preserve?

As a result of feedback Williams has received from stakeholders during the FERC pre-filing process, we have made adjustments to more than 20 percent of the Central Penn Line, including adjusting the route so that it bypasses environmentally sensitive areas such as Tucquan Glen and Shenks Ferry. Although project mapping provided to FERC shows the original route through Tucquan Glen, that route is no longer being pursued. Rather, in future mapping it will be depicted as an alternative – only because it is a route that was evaluated, not because it is a route that we are currently pursuing.
