Answer:
The statement is true
Step-by-step explanation:
The call to 811 allows affected facility operators to locate and mark their underground facilities in the area in which someone needs digging. Call 811 at least a few days before you start any digging project. Whether you are planning to do it yourself or hire a professional, smart digging means calling 811 before each job. But if one has called once and doing digging at the same location then there is no need to call 811 again.
