Do I have to call if I am digging on my own property?

Yes.  You are required to inform the utilities of any type of work involving the movement of earth with powered equipment.

Who should make the call?

The person who is doing the digging should place the one call notification. If you are a homeowner and you’ve hired an excavator to do the work, the excavator is required by law to call to have lines located (refer to Section 5 of PA Act 287).

How deep must I dig before I am required to call?

What are PA One Call’s hours of operations?

The call center is open 24-hours a day, 7 days a week, every day of the year.

How many days do I have to wait before I can begin digging?

State law requires a three (3) business day notice (does not include state holidays or weekends). A business day begins at 12:00:00 a.m. and ends at 11:59:59 p.m.  This means call on Monday or Tuesday if your digging project starts on the weekend.

What are the state holidays?

State holidays are New Year’s Day, Martin Luther King, Jr. Day, President’s Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veteran’s Day, Thanksgiving Day, Day after Thanksgiving and Christmas Day.

Do I have to mark the site in white?

You are required to mark the site in white unless you give exact site information. Marking the site means you are helping the person locating your lines to know exactly where you are digging. It also may help to get the lines marked in the correct location without any delay in your work schedule.

Who marks the lines?

Each member facility owner is responsible for sending someone to the site to mark their underground lines. Some facility owners send their own employees while others hire professional locating companies to do it. Pennsylvania One Call System does not mark the lines.

What do the colors mean?

PA law follows the Common Ground Alliance Best Practices for Temporary Marking (ANSI standard Z535). White, proposed excavation; Pink, temporary survey markings; Red, electric power lines, cables, conduits and lighting cables; Yellow, gas, oil, steam, petroleum or gaseous materials; Orange, communication, alarm or signal lines, cables or conduits and traffic loops; Blue, potable water; Purple, reclaimed water, irrigation and slurry lines; and, Green, sanitary and storm sewer lines.

Do I have to call every 10 days if I am still working on the site?

If an excavator removes their equipment and vacates a work site for more than two (2) business days, the excavator must notify the one call center again. It is the excavator’s responsibility to maintain the marks. Marks that have been removed, moved or otherwise tampered with are never accurate and prove to be deadly.

What should I do if a utility company does not mark their lines?

You may begin digging after the 3 business days have expired if you exercise due care. But why would you chance it? PA One Call can notify the specific member facility owner again and let them know you are waiting for their immediate response. Remember, facility owners will only mark the lines they actually own. Some facility owners do not mark the service lines because they are owned by the property owner.

What should I do if I smell gas?

If you smell gas, contact 9-1-1 and the local gas company. If you do not know the gas company’s telephone number, call us at 8-1-1. You will need to know the county and municipality you are located in order to report the incident. Review the Pipeline Safety Bulletin for instructions on how to react to a gas leak.
