Safe Digging begins with you!

pipelinemarkerBefore you begin your excavation, ensure the safety of your personnel and the public by following the checklist below:

  • Learn what the state and federal laws are regarding safe excavation practices.
  • Know what your job requirements are and obtain the proper permits. Show gas and other utility lines on construction plans.
  • Use white paint to identify the proposed excavation site or running line.
  • Call Arizona 811 or go online at least two (2) full working days before excavation, (excluding Saturdays, Sundays, and legal holidays) to have all underground facilities located and marked.
  • Know the markings and the color codes that identify underground utility lines.
  • Observe where utilities are located, by line markers or markings on the ground.  Respect and protect the marks.
  • Have utility lines re-marked if initial markings are destroyed or more than fifteen (15) days old.
  • Train employees on the  proper excavation of natural gas lines and all underground facilities. When excavation approaches gas lines, employees must expose lines by careful probing and hand digging.  Free training for your organization.
  • Train employees on how to identify and report a gas leak/gas emergency.
    • Smell:   An odor, similar to rotten eggs.
    • Hear:    An unusual hissing sound coming from a pipeline, appliance, or natural gas meter.
    • See:    Unusual changes to soil, dead or dying vegetation.

Call 480-644-4277 (GASS) to report damages to City of Mesa gas facilities. 
For damages resulting in the escape of natural gas, call  911 and 480-644-4277 (GASS).

Arizona 811:

Arizona 811 was established by utility owners as a one-call notification system to assist homeowners and excavators in identifying the location of underground utilities to prevent damages to facilities.

Calling 811 could potentially help save lives and protect infrastructure.  Knowing where underground utility lines are buried before each digging project helps protect you from personal injury, expense and penalties. There may be multiple utility lines in the same area at varying depths.  Even simple digging projects can damage utility lines and disrupt vital services to an entire community.  Having underground utilities located can help prevent undesired consequences.

Statewide: 811 or 1-800-STAKE-IT                                     Maricopa County: 811 or 602-263-1100

Arizona's Underground Facilities Law:

State law requires all excavators to first determine whether underground facilities will be encountered and take measures to protect these facilities. A person who violates any provision of this law could be subject to civil penalties in an amount up to $5,000.00 (A.R.S. 40-360.28).

For more information on Arizona's Underground Facilities Law (Article 6.3), visit the Arizona Corporation website.

City of Mesa Requirements:

Right-of-Way Permits
The City of Mesa requires that all excavators obtain a Right-of-way (ROW) Permit prior to any excavation in the ROW. Excavators failing to comply with the conditions noted on the permit can, and will be issued a "stop work" order and will not be permitted to proceed until corrective action is taken.

Blasting Permits
If blasting will be performed on your jobsite within the City of Mesa's natural gas service area (Mesa/Pinal County), contact Mesa Fire at  480-644-2622 or Pinal County at 520-866-6405.  After notification, Energy Resources will review permits and locate all gas pipelines in the proposed blasting area.  A gas leakage survey will be performed at NO CHARGE prior to, and within 24 hours after, any blasting that occurs within 200 feet of any gas pipeline.

Boring Requirements
If boring, follow City of Mesa Bore Requirements (Detail No.18 and 18.1) and call 480-644-5517 or 480-644-3513 to schedule a bore monitor for your jobsite.

Check-n-Wrap Program
If a gas line is exposed during excavation, you are required to notify the City of Mesa immediately at 480-644-2261.  An inspector will come out and visit the worksite to check for damages to the pipe and ensure that the exposed pipe is properly protected with backfill material.  This is a free inspection!

Excess Flow Valves (EFV's)
Be aware that EFV's are installed on new/renewed single family home gas service lines and are designed to limit the flow of gas in the event a line is damaged.  More on EFV's
