Excavators & Contractors


Excavation equipment is one of the leading causes of damage to pipelines each year.  Hitting a pipeline can result in serious injuries and even fatalities.  Whether you’re working with a shovel or a 4-ton backhoe, you must make damage prevention your number one priority.  

 Call 811 before you dig—it’s your responsibility and it’s the LAW!



Make the Request

In compliance with state law, Call 811 at least three (3) working days before you dig to have underground utilities located and marked near your job site.  


Wait 3 Full Working Days

Assist locators by pre-marking your job site.  Remember locators must be able to access the excavation site.    With Positive Response 360, the locator will update you on the completion status.

step3 Dig Safely

Once lines are marked, dig with care using hand-digging and vacuum-digging tools near underground lines and within the 24-inch tolerance zone on either side of the markings.   Mechanical equipment should not be used to expose underground lines.


 Notify us IMMEDIATELY about Damage or Leaks                                            

Even when pipes are properly marked, accidents can happen.  If you accidently nick or scrape a pipe, damage or cut the wire or marker tape buried near the pipe, or even see minor damage to a pipe - call us at 1-866-201-1001 so we can come out and inspect the area for potential damage.    Do NOT cover a pipeline that may have damage.  Gas can leak and migrate into homes and buildings endangering the safety of others.

If you suspect a gas leak or contact with a natural gas pipe Be aware of work conditions
  • STOP all work
  • Leave the premises immediately and instruct others to stay away
  • Contact YCNGA at 1-866-201-1001
  • Call 911
  • Do not operate any equipment
  • Eliminate any source of ignition
  • Do not operate any pipeline equipment or valves.
During the excavation process, be alert to any of the following conditions that may signal a natural gas leak:
  • Hissing sounds
  • Natural gas odor
  • Blowing dirt
  • Bubbling water


Pipeline Markers


Marker clear

Underground natural gas pipelines are sometimes identified by markers placedat intervals along pipeline rights-of-way. Pipeline markers are important to your safety. While the markers are very helpful for indicating the presence of pipelines in the area, they don't show the exact location, depth, or how many pipelines are in the right-of-way. Don't rely solely on the presence or absence of a pipeline marker.  Markers may not be installed along local distribution lines and local distribution line right-of-ways.  You must still call 811 before beginning any excavation projects.
