PA One Call

All excavators must contact PA One Call at least 3 business days prior to excavation, as required by law.

Pennsylvania One Call System is a non-profit Pennsylvania corporation created to protect the underground facilities before anyone begins to disturb the earth. PA One Call receives requests from excavators, contractors, plumbers, builders, designers, and the general public to find out where underground lines are located. Pennsylvania One Call notifies member underground facility owners of the intent to excavate. The member underground facility owner then marks where their lines are located.

The PUC representative on the Board of Directors of Pennsylvania One Call is the supervisor of the Gas Safety Section.
