If your an UG Contractor, you MUST CALL 811 prior to any digging operation. If you want to find the laws for such operations, go to https://Safeexcavator.com The National Excavator Initiative host, CEO and producer Mike Rowe of (dirty jobs fame) will be running public notice awareness of the importance of call before you dig as there are some 7 million miles of UG buried utility infrastructure lines in existence in USA.
