Frequently asked questions

I called 811 and waited, now what?

Once you are within the legal start dates, check your responses via your method of choice. You should have a "Clear" or "Marked" response from each individual utility. If you have not received a response from a particular utility, call 811 immediately and specify the utility that has not yet responded. Do not assume it is safe to dig because there was no response.

Thank you for your response.

I called 811 and had lines marked, but due to the work the marks are no longer visible. What should I do?

As an excavator, it is your responsibility to preserve the marks that have been placed on the ground. However, sometimes the work does not always allow this to happen. If the marks are no longer visible, dial 811 to have facility owners come back to re-mark their lines.

Thank you for your response.

Do I need to call 811 if I plan to demolish a building?

Yes, you need to call if you plan on doing any demolition work. Demolition can affect underground utilities, especially if there are service lines in the area.

Thank you for your response.

How deep is the gas line?

The depth of the underground utility lines vary from location to location based on a number of factors. There is no way to know the precise depth of a gas line that is buried underground, which is why it is so important to call 811 to have the facility owners come out and mark the lines. Always be sure to expose gas lines by hand digging when working on your project.

Thank you for your response.

Please call us at 1-800-440-6111. We can evaluate your site and determine availability and provide details about the main line extension process.

What should I do if I damage an underground gas line?

If you damage a natural gas line and gas is blowing, leave the area immediately and call 911. Then, call us at 1-800-544-5606. Do NOT try to block the flow of gas. There may be hidden damage that could be worsened by building pressure. Stay clear of the area. Once the area is safe, turn off the equipment and try to eliminate potential ignition sources. The first priority is the protection of life. After 911 has been notified, you may also contact 811.

Thank you for your response.
