Filing a Petition To Intervene is the only way to become a party in the case and have legal standing in an appeal. There are two choices if you decide not to file a petition to intervene in the case:
- Provide public input at a public hearing (if one is held) Testimony made upon oath or affirmation at a public input hearing will be considered by the administrative law judge when rendering a decision in the case
- Submit written comments regarding the Application with the Secretary of the Commission which will be placed in the public comment folder of the case and may be reviewed by the Commission. However, written comments are not evidence and will not be considered by the administrative law judge in rendering a decision in the case.

Mid -Atlantic Resiliency Link (MARL) / Gore-Doubs-Goose Creek - 500kV
The Mid -Atlantic Resiliency Link (MARL) and Gore-Doubs-Goose Creek projects are two segments of the same transmission line. The energy is being pulled from multiple West Virginia power plants from the 502 Junction in Pennsylvania to the delivery point - the Goose Creek Substation - in Loudoun County's Data Center Alley. Pennsylvania is only impacted by NextERA's Mid -Atlantic Resiliency Link (MARL) segment. NextERA plans to take a new 200' easement for their portion of the 500kV line through Fayette and Greene Counties in Pennsylvania.
There is no federal backstop for siting this line. If any one of the states denies it the transmission line will not be built.
If you are intervening be sure to include a request for the PSC that if the line is not denied by Pennsylvania, that the approval be contingent on all of the transmission line components - both the Mid -Atlantic Resiliency Link (MARL) and Gore-Doubs-Goose Creek segments - being approved in all other states (West Virginia, Maryland and Virginia).
