After utility lines have been marked, you should always expose them by hand to verify their location before using power equipment near them. If you can't find them, please let us know.

What should I do if I see someone digging without marks?
When you see someone digging without first having their utilities located marked, simply call 811 to speak to a Notification System Representative (NSR). Tell them that you would like to place a No Marks ticket. This ticket will only be accepted through the MISS DIG 811 Notification Center; this cannot be placed online through any of our web programs.
